In an increasingly aging society, age has become a foundational dimension of social grouping broadly targeted by advertising and governmental policies. However, perception of old age induces mainly strong negative social biases. To characterize their cognitive and perceptual foundations, we modeled the mental representations of faces associated with three age groups (young age, middle age, and old age), in younger and older participants. We then validated the accuracy of each mental representation of age with independent validators. Using statistical image processing, we identified the features of mental representations that predict perceived age. Here, we show that whereas younger people mentally dichotomize aging into two groups, themselves (younger) and others (older), older participants faithfully represent the features of young age, middle age, and old age, with richer representations of all considered ages. Our results demonstrate that, contrary to popular public belief, older minds depict socially relevant information more accurately than their younger counterparts. Copyright © 2014 The Authors.

Stressful life events (SLEs) have been linked to depression, anxiety, and reduced life satisfaction. The inoculation hypothesis of aging suggests older adults may be less vulnerable to poor psychological outcomes following SLEs than working-age adults. The current study compared relationships between SLEs, mood and life satisfaction among older adults (65+), and adults aged 50-64, and investigated whether group identification and loneliness moderate these relationships. A community-based sample of 121 Scottish participants responded to measures of SLEs (modified Social Readjustment Rating Scale), symptoms of depression and anxiety (Hospital Anxiety and Depression Scale), life satisfaction (Life Satisfaction Index A), group identification (Group Identification Scale), and loneliness (UCLA Loneliness Scale). In the 50-64 age group, the number of SLEs was significantly associated with greater symptoms of depression and anxiety, and reduced life satisfaction. Group identification and loneliness did not moderate these relationships. There were no significant relationships in the older adult group. The finding of relationships in working-age, but not older adults, supports the inoculation hypothesis of aging. Further research to better understand changes across the lifespan, and inter-relationships with related variables, would be valuable from both theoretical and clinical perspectives.

Purpose: Breast cancer incidence increases with age and is a major cause of morbidity and mortality in elderly women, but is not well studied in this population. Comorbidities often impact on the management of breast cancer in elderly women. Methods and Materials: From 1979 to 2002, a total of 238 women aged 70 years and older with Stage I or II invasive carcinoma of the breast underwent breast-conservation therapy. Outcomes were compared by age groups and comorbidities. Median age at presentation was 74 years (range, 70-89 years). Age distribution was 122 women (51%) aged 70-74 years, 71 women (30%) agedmore » 75-79 years, and 45 women (19%) aged 80 years or older. Median follow-up was 6.2 years. Results: On outcomes analysis by age groups, 10-year cause-specific survival rates for women aged 70-74, 75-79, and 80 years or older were 74%, 81%, and 82%, respectively (p = 0.87). Intercurrent deaths at 10 years were significantly higher in older patients: 20% in those aged 70-74 years, 36% in those aged 75-79 years, and 53% in those 80 years and older (p = 0.0005). Comorbidities were not significantly more common in the older age groups and did not correlate with cause-specific survival adjusted for age. Higher comorbidity scores were associated with intercurrent death. Conclusions: Older age itself is not a contraindication to standard breast-conservation therapy, including irradiation. Women of any age with low to moderate comorbidity indices should be offered standard breast-conservation treatment if otherwise clinically eligible.« less

Purpose: Lesbian, gay, bisexual, and transgender (LGBT) people are a health disparate population as identified in Healthy People 2020. Yet, there has been limited attention to how LGBT older adults maintain successful aging despite the adversity they face. Utilizing a Resilience Framework, this study investigates the relationship between physical and mental health-related quality of life (QOL) and covariates by age group. Design and Methods: A cross-sectional survey of LGBT adults aged 50 and older (N = 2,560) was conducted by Caring and Aging with Pride: The National Health, Aging, and Sexuality Study via collaborations with 11 sites across the U.S. Linear regression analyses tested specified relationships and moderating effects of age groups (aged 50–64; 65–79; 80 and older). Results: Physical and mental health QOL were negatively associated with discrimination and chronic conditions and positively with social support, social network size, physical and leisure activities, substance nonuse, employment, income, and being male when controlling for age and other covariates. Mental health QOL was also positively associated with positive sense of sexual identity and negatively with sexual identity disclosure. Important differences by age group emerged and for the old–old age group the influence of discrimination was particularly salient. Implications: This is the first study to examine physical and mental health QOL, as an indicator of successful aging, among LGBT older adults. An understanding of the configuration of resources and risks by age group is important for the development of aging and health initiatives tailored for this growing population. PMID:25213483

Ageism, a form of prejudice in which one relates negatively to people due to their age, exists throughout life. However, no attempt has been made to compare ageist attitudes across the life cycle, from young adulthood to old age. Consequently, the current study examined age and gender differences in ageism throughout adulthood. 955 Israeli participants (age range: 18-98 years) were divided into three age-groups: young (18-39), middle-aged (40-67), and old (68-98), and were administered the Fraboni Scale of Ageism. Age and gender differences were examined both for the three groups and for subgroups within the older adult cohort. Multivariate analysis of variance revealed that middle-aged participants were significantly more ageist than younger and older groups. Across all age groups, men exhibited more avoidance and stereotypical attitudes toward older adults than women. Among the old age group, participants aged 81-98 held more ageist stereotypes and reported more avoidance of older adults than those aged 68-73. Within the older adult cohort, gender was a significant predictor for ageist attitudes among those aged 68-73 and 81-98, but not for people aged 74-80. Ageism demonstrates a changing pattern across the life span. While gender differences remain stable, ageist attitudes toward growing old as we age ourselves are constantly changing. In order to gain a better understanding of ageism as a general and global phenomenon, we need to consider the role of such attitudes in different stages of life.

This study examines whether unconscious priming of attitudes towards older age might change the self-efficacy of older employees, and thus modify their performance at work. Three age- and gender-matched groups of 20 participants were primed with positive, negative or no age stereotypes by means of the scrambled sentence task, and were then transferred to a cognitively demanding PC-based mail-sorting task. Participants' accuracy on the latter task was significantly higher in the positively primed group than in the unprimed group, and was significantly lower in the negatively primed group than in the unprimed group, except for one parameter. These findings indicate that the performance of older workers may indeed be modifiable by unconscious priming. Practitioner Summary: This study analyses whether unconscious priming attitudes towards older age might modify work performance. Participants were primed with the scrambled sentence task and then conducted a cognitive mail-sorting task. The findings indicate that the performance of older workers may indeed be modifiable by unconscious negative as well as positive priming.

To investigate whether idiom production was vulnerable to age-related difficulties, we asked forty younger (ages 18-30) and forty older healthy adults (ages 60-85) to produce idiomatic expressions in a story-completion task. Younger adults produced significantly more correct idiom responses (73%) than older adults (60%) did. When older adults generated partially correct responses, they were less likely than younger participants to eventually produce the complete target idiom (Old: 32 % / Young: 70%); first-word cues after initial failure to retrieve an idiom resulted in more correct idioms for older (24%) than younger (15%) participants. Correlations between age and idiom correctness were positive for the Young group, and negative for the Older group, suggesting mastery of familiar idioms continues into adulthood. Within each group, scores on the Boston Naming Test correlated with performance on the idiom task. Findings for retrieving idiomatic expressions are thus similar to those for retrieving lexical items. PMID:21728830

The aim of study was to examine echocardiographic indices of right heart chambers in patients with coronary artery disease in different age groups. On 678 patients aged 38-85 years, who underwent echocardiography, are including with the use of spectral tissue Doppler. Obtained 2 age groups: 1st - patients up to 60 years (n=282) and group 2nd - patients 60 years and older (n=396). In the analysis the obtained results in patients with coronary heart disease in older age groups showed an increase in right ventricular wall thickness, systolic and average pressure in the pulmonary artery. These changes were accompanied by deterioration in left ventricular diastolic function, while the systolic function of the left and right ventricle were independent of age. Thus, the results can be recommended for assessment of right ventricular dysfunction in patients of older age groups.

There is increasing research aimed at addressing whether patients with borderline personality disorder (BPD) may exhibit variations in symptomatology and functioning according to their chronological age. The current study consisted of 169 outpatients diagnosed with BPD, who were divided into four age groups as follows: 16-25 years (n = 41), 26-35 years (n = 43), 36-45 years (n = 45), and 46 and more years (n = 40). Age groups were compared for symptomatology, normal personality traits, psychiatric comorbidities, functioning, and treatment-related features. The younger group had significantly higher levels of physical/verbal aggression and suicide attempts relative to the older group. Conversely, the older group had significantly greater severity of somatization, depression, and anxiety symptoms. In addition, the older group showed significantly greater functional impairment overall and across physical/psychological domains, specifically when compared to the younger group. Overall, these findings may suggest that age-related symptoms should be considered when diagnosing BPD. Also, functional impairments should be the target interventions for older BPD patients.

Against the background of population aging, older peoples dance has attracted attention in research and its health promoting effects and social meanings have been brought to the fore. In this article we focus on the context and power dimensions of dance with an emphasis on the organizing of dance among older adults in terms of social discourses and age relationships. On the basis of qualitative interviews with 33 older dancers and 11 dance providers in Sweden, the study illustrates how dance is organized through social discourses on healthism and on the increasing group of older people as a powerful consumer group. The study highlights that older people and their social dance contexts are marked and subordinated in relation to younger age groups through non-verbal practices such as choreography and temporal codes. In short, dancing among older adults is not only a common health promoting and social activity, but also an arena in which age and age normality are negotiated and constructed.

Sleep disturbances are common among older people (>65 years). Further, long-term use of sedative hypnoticsin older people is associated with morbidity and mortality. However, older people represent a large span of life years, and few studies have included the oldest-old above 85 years. To investigate and compare sleep quality, use of hypnotics and sleeping habits in different age groups of the older population in the Scania region, Sweden and in relation to sociodemographic- and functional status. A cross-sectional population-based study including 2931 people aged 60-93 years from five different municipalities in Scania was performed during 2001-2004. The sample was divided into age groups, young old (60-72 years), old-old (78-84 years) and oldest-old (87-93) years. Data constitutes of sleep related questions, sociodemographic- and functional status from the study 'Good Ageing in Skane'. Descriptive statistics were used to describe sleep quality, hypnotics use and sleeping habitsin relation to sociodemographic- and functional status. The aim was to investigate associations, not the magnitude of associations between variables. In all age groups, those who used hypnotics and were living alone had significantly poorer sleep quality and shortest sleeping time than nonhypnotic users and those who lived together. A significant increase of hypnotics and frequency of use was seen with increasing age. Frequency of napping increased significantly with degree of dependence in all age groups and with increasing age. Insomnia is still a problem and hypnotic use has not improved sleep for a large number of older people. Hypnotics are effective as short-term treatment, however, nonpharmacological interventions and psychological and behavioural therapies should be considered for treating older people with chronic insomnia.

We present an age-stratified prospective assessment of urinary and sexual function of 300 patients after robot-assisted laparoscopic prostatectomy (RALP). Subjective assessment data of continence and potency were collected for different age groups (<50, 50-59, and > or =60 years old) preoperatively, and at 1, 3, 6, and 12 months after RALP. Health-related quality of life questionnaires evaluated return of baseline urinary and sexual function at the same time intervals. The three age groups included 21, 129, and 150 patients (aged <50, 50-59, and >60 years old, respectively). Using Kaplan-Meier curves, younger men achieved subjective continence significantly earlier than older age groups when age groups were compared using a 60-year-old cut-off point (P = 0.02). However, subjective continence was noted to be equal among all age groups after 1 year of follow-up. Time to recovery of subjective potency among age groups shows a significant difference in favor of the younger age group (P = 0.01) Objective urinary function is equal between age groups at all time points, while objective sexual function assessment showed a trend toward better results in the younger age group. Younger men will likely have an earlier return of continence and potency compared to older men after RALP. However, continence outcomes were noted to be equal among age groups after I year of follow-up, while younger men continue to report superior potency outcomes compared to older men over the first postoperative year. Such findings are valuable in counseling older men undergoing this procedure.

The incidence of acute kidney injury (AKI) rises with age and is associated with multiple risk factors. Here, we compared the risk factors for AKI between younger and older incident diabetic patients to examine the trends in risk alteration for individual factors across different age groups. Between 2007 and 2013, we selected all incident type 2 diabetic adults from the Taiwan National Health Insurance registry, stratified based on age: young (< 65 years), old (≥ 65 but < 75 years), and older-old (≥ 75 years). All factors with potential renal influence (e.g., comorbidities, medications, and diagnostics/procedures) were recorded during the study period, with a nested case-controlled approach utilized to identify independent risk factors for AKI in each age group. Totally, 930,709 type 2 diabetic patients were categorized as young (68.7%), old (17.7%), or older-old (13.6%). Older-old patients showed a significantly higher incidence of AKI than the old and the young groups. Cardiovascular morbidities (hypertension, atrial fibrillation, acute coronary syndrome, and cerebrovascular disease) were shown to increase the risk of AKI, although the risk declined with increasing age. Chronic obstructive pulmonary disease and receiving cardiac catheterization elevated the risk of AKI preferentially in the older-old/old and older-old group, respectively, while the administration of angiotensin-converting enzyme/α-blocker and angiotensin receptor blocker/calcium channel blocker reduced the risk of AKI preferentially in the older-old and older-old/old group, respectively. In conclusion, our findings highlight the importance of devising age-specific risk factor panels for AKI in patients with recently diagnosed type 2 diabetes.

Purpose The purpose of the study was to examine the relationships among measures of comprehension and production for stories depicted in wordless pictures books and measures of memory and attention for 2 age groups. Method Sixty cognitively healthy adults participated. They consisted of two groups—young adults (20–29 years of age) and older adults (70–89 years of age). Participants completed cognitive measures and several discourse tasks; these included telling stories depicted in wordless picture books and answering multiple-choice comprehension questions pertaining to the story. Results The 2 groups did not differ significantly for proportion of story propositions conveyed; however, the younger group performed significantly better on the comprehension measure as compared with the older group. Only the older group demonstrated a statistically significant relationship between the story measures. Performance on the production and comprehension measures significantly correlated with performance on the cognitive measures for the older group but not for the younger group. Conclusions The relationship between adults’ comprehension of stimuli used to elicit narrative production samples and their narrative productions differed across the life span, suggesting that discourse processing performance changes in healthy aging. Finally, the study’s findings suggest that memory and attention contribute to older adults’ story processing performance. PMID:21106701

Acute stress disorder in older, middle-aged and younger adults in reaction to the second Lebanon war.

To compare rate of acute stress disorder (ASD) and intensity of acute stress symptoms (ASS) in younger, middle-aged and older Israeli citizens exposed to missile attacks during the second Lebanon war. A telephone survey of a random sample of residents in the northern area of Israel was conducted in July 2006, during the third week of Lebanon war. Respondents were divided into groups aged 18-40, 41-69 and 70+. ASD and ASS were measured by the Acute Stress Interview questionnaire and by war-related exposure variables and demographic data. Exposure variables were similar in the three age groups. Older respondents reported lower intensity of ASS and obtained lower means for each of the symptoms criteria than the young adults, while the middle-aged adults were in between the younger and the older group. ASD criteria were met by 13.2% of the younger, 4.7% of middle-aged and 4.3% of older respondents (p > 0.05), and subsyndromal ASD was found in 20.5%, 14.1% and 4.4% (p < 0.05) respectively. Twenty-two percent of ASS variance was explained by younger age, female gender and higher perceived proximity to missile falling. Older adults reacted to the war situation with lower level of acute stress symptoms. Long-term effects of war on different age groups should be further studied.

All patients greater than 50 years of age (N = 96) admitted with a pre- or postoperative diagnosis of acute appendicitis from 1971 to 1980 were reviewed. A comparative series of 91 patients aged 25 to 50 years was similarly reviewed. Noninflammatory diseases of the appendix and incidental appendectomies were excluded. Detailed study of symptoms, clinical presentation, laboratory evaluation, radiographic evaluation, concomitant diseases, hospital course, surgical findings, complications, and mortality were completed. Comparison of patients aged 25 to 50 to patients older than 50 years revealed a statistically significant increased incidence of perforation in the older group (p less than 0.0001). Sixty-five per cent of the older group showed greater incidence of perforation. Further analysis of this series yields the hypothesis that the increased incidence of perforation is related to a significant decrease in the frequency of classic presentation in the greater-than-50 age group, a significant decrease in frequency of correct admission diagnosis and a significant delay between admission and surgical procedure in the older group. A more rapid pathophysiologic progression of appendicitis with increasing age was noted. A much higher percentage of older patients was undiagnosed until the surgical procedure. In this group, there was a longer duration of symptoms, less frequent classic presentation, and decreased frequency of right lower quadrant guarding and tenderness as compared to patients with correct diagnosis prior to surgery. Complications were much more frequent in older patients and higher still in those with perforation. Analysis of findings by decade of life revealed an anticipated high incidence of perforated appendicitis in patients greater than 50, but also showed a continuation of the high incidence of perforation into the decade 40 to 50. There were three deaths in the entire study group (1.6%) all occurring in the older age group with postoperative sepsis. PMID:4004382

Our primary objective in this study was to quantify whole brain and regional cerebral metabolic rates of glucose (CMRg) in young and older adults in order to determine age-normalized reference CMRg values for healthy older adults with normal cognition for age. Our secondary objectives were to--(i) report a broader range of metabolic and endocrine parameters including body fat composition that could form the basis for the concept of a 'metabolic phenotype' in cognitively normal, older adults, and (ii) to assess whether medications commonly used to control blood lipids, blood pressure or thyroxine affect CMRg values in older adults. Cognition assessed by a battery of tests was normal for age and education in both groups. Compared to the young group (25 years old; n = 34), the older group (72 years old; n = 41) had ~14% lower CMRg (μmol/100 g/min) specifically in the frontal cortex, and 18% lower CMRg in the caudate. Lower grey matter volume and cortical thickness was widespread in the older group. These differences in CMRg, grey matter volume and cortical thickness were present in the absence of any known evidence for prodromal Alzheimer's disease (AD). Percent total body fat was positively correlated with CMRg in many brain regions but only in the older group. Before and after controlling for body fat, HOMA2-IR was significantly positively correlated to CMRg in several brain regions in the older group. These data show that compared to a healthy younger adult, the metabolic phenotype of a cognitively-normal 72 year old person includes similar plasma glucose, insulin, cholesterol, triglycerides and TSH, higher hemoglobin A1c and percent body fat, lower CMRg in the superior frontal cortex and caudate, but the same CMRg in the hippocampus and white matter. Age-normalization of cognitive test results is standard practice and we would suggest that regional CMRg in cognitively healthy older adults should also be age-normalized.

2015-01-01

Learning and memory abilities tend to decline as people age. The current study examines the question of whether a learning situation that emphasises collaborative social interaction might help older persons overcome age-related learning and memory changes and thus perform similarly to younger persons. Younger and Older participants (n = 34 in each group) completed the Barrier Task (BT), a game-like social interaction where partners work together to develop labels for a set of abstract tangrams. Participants were also administered standard clinical neuropsychological measures of memory, on which the Older group showed expected inferiority to the Younger group. On the BT, the Older group performed less well than the Younger group early on, but as the task progressed, the performance of the Older group caught up and became statistically indistinguishable from that of the Younger group. These results can be taken to suggest that a learning milieu characterised by collaborative social interaction can attenuate some of the typical memory disadvantages associated with being older.

Greater Perceived Similarity between Self and Own-Age Others in Older than Young Adults

2017-01-01

As people age, they increasingly incorporate age-stereotypes into their self-view. Based on this evidence we propose that older compared to young adults identify to a greater extent with their own-age group on personality traits, an effect that may be particularly pronounced for positive traits. Two studies tested these hypotheses by examining associations in young and older adults between evaluations of self and own-age others on personality traits that varied on valence. In both studies, young and older participants rated personality trait adjectives on age typicality, valence, and self typicality. Converging results across both studies showed that older compared to young participants were more likely to endorse personality traits as self-typical when those traits were also perceived as more typical for their own-age group, independent of whether age was made salient to participants prior to evaluation. In addition, there was evidence that the association between evaluations of self and own-age others in older participants was greater for more positive personality traits. This age-differential pattern is discussed in the context of increased age salience in aging and its effect on the similarity between evaluations of self and own-age others in older compared to young adults.

In the limited research into suicides in older adults, they have been treated as a homogenous group without distinguishing between different age groups. This study aimed to compare differences in sociodemographic variables, recent life events, and mental and physical illnesses between three age groups within older adults who died by suicide: young-old (65-74 years), middle-old (75-84 years), and oldest old (85 years and over) in Queensland, Australia, during the years 2000-2012 (N = 978). The Queensland Suicide Register was utilized for the analysis. Annual suicide rates were calculated. Odds ratios with 95% confidence intervals and χ 2 tests for trend were calculated to examine differences between the three groups. Suicide rates were increasing with age for males, but not for females. Hanging and firearms were the predominant methods of suicides. However, suffocation by plastic bag and drowning as suicide methods increased with age, in contrast firearms and explosives decreased with age. Overall, psychiatric problems, suicidal behavior, legal and financial stressors, and relationship problems decreased significantly with age, meanwhile physical conditions and bereavement increased with age. Suicide across older adulthood is not a homogenous phenomenon. Our findings showed significant differences in the prevalence of potential risk factors within the three different age groups considered. To prevent suicide in older adults would require targeting specific factors for each subgroup while using holistic and comprehensive approaches.

Ageing and the group-reference effect in memory.

Lee, Hyeon-Nyeon; Rosa, Nicole M; Gutchess, Angela H

2016-07-01

The present study examines age differences in the memory benefits from group-referncing. While prior work establishes that the memory performance of younger and older adults similarly benefits from relating information to the self, this study assessed whether those benefits extend to referencing a meaningful group membership. Young and older adult participants encoded trait words by judging whether each word describes themselves, describes their group membership (selected for each age group), or is familiar. After a retention interval, participants completed a surprise recognition memory test. The results indicate that group-referencing increased recognition memory performance compared to the familiarity judgements for both young and older groups. However, the group-reference benefit is limited, emerging as smaller than the benefit from self-referencing. These results challenge previous findings of equivalent benefits for group-referencing and self-referencing, suggesting that such effects may not prevail under all conditions, including for older adults. The findings also highlight the need to examine the mechanisms of group-referencing that can lead to variability in the group-reference effect.

Satisfaction with life is a complex interplay of older people's perspectives on life achievements. Satisfaction with life, alongside health and functional ability contribute to successful ageing. To explore the impact of increasing age on older people's perceptions of their health, functional ability and life satisfaction. A cross-sectional survey of non-institutionalised older people (65+) was conducted (n = 542). The Short Form-12 Health Survey measured perceived physical and mental health, the Groningen Activity Restriction Scale measured functional ability and the Satisfaction With Life Scale measured life satisfaction. Significant group differences were found; while participants' perceptions of health and function decreased with age, perceptions of life satisfaction increased. Unexpectedly, the youngest groups reported low levels of life satisfaction while the oldest reported very high levels. Further study should consider factors that might influence the perception of health, functional ability and particularly life satisfaction across older age groups.

Nursing students' interest in older people nursing needs to be enhanced, as there is a demand for competent nurses who prefer to work in older people nursing. Educational approaches involving older people are encouraging; they increase positive learning outcomes. The aim of this study was to evaluate the outcomes of the Learning with Older People Programme (LOPP) in terms of nursing students' interest in older people nursing, their attitudes towards older people and their knowledge level about ageing. A quasi-experimental, pre-post-test design with non-equivalent comparison group was used. Two different Finnish nursing schools geographically apart from each other. A nonprobability, convenience sample of nursing students (n=87; n=46 in the intervention group, n=41 in the comparison group) in the middle of their 3.5 year bachelor degree studies and enrolled in compulsory theoretical older people nursing courses participated in the study. Data were collected in 2014 using a structured questionnaire that included background questions, students' interest in older people nursing as a primary outcome measure and their attitudes towards older people and knowledge level about ageing as secondary outcome measures. The data were analysed statistically. In the intervention group, students' interest in older people nursing was significantly higher and their attitudes towards older people were more positive than those of students in the comparison group. There were no significant differences between the groups in terms of the students' knowledge level about ageing. An educational approach involving older people resulted in encouraging outcomes. It is worth considering whether or not older people could be a valuable resource for nursing education. Copyright © 2015 Elsevier Ltd. All rights reserved.

Prospective memory and frontal lobe function.

2016-01-01

The study sought to examine the role of frontal lobe functioning in focal prospective memory (PM) performance and its relation to PM deficit in older adults. PM and working memory (WM) differences were studied in younger aged (n = 21), older aged (n = 20), and frontal injury (n = 14) groups. An event-based focal PM task was employed and three measures of WM were administered. The younger aged group differed from the other two groups in showing significantly higher scores on PM and on one of the WM measures, but there were no differences at a statistically significant level between the older aged group and the frontal injury groups on any of the memory measures. There were, however, some differences in correlations with a WM measure between groups. It is concluded that there are similarities and differences in the deficits in PM between older adults and patients with frontal lobe injury on focal as well as nonfocal PM tasks.

To explore the differences in various tinnitus-related features and psychological aspects between the younger and older adult patients with tinnitus. We retrospectively reviewed the clinical data of the adult patients who visited our tinnitus clinic in 2013 and completed full tinnitus assessment including audiometry, tinnitus matching, standardized tinnitus questionnaires, and psychometric questionnaires. The younger group included patients aged 20-45 years (n=64), and the older group, those older than 65 years (n=76). Clinical features, hearing levels, matched tinnitus pitches and loudness, self-report tinnitus severity scores, Beck depression inventory scores, and stress scores were compared between the groups. Tinnitus duration was longer in the older group (p=0.002). Mean PTAs were 16dB HL in the younger, and 38dB HL in the older groups (p<0.001). Eighty-nine percent of the younger patients had normal hearing, while 82% of the older patients had hearing loss (p<0.001). Matched tinnitus loudness was greater in the older group (64dB HL vs. 36dB HL, p<0.001). All of the self-report tinnitus, depression, and stress scores did not differ between the groups. The older patients seemed to be more receptive to tinnitus. The majority of older tinnitus patients had concomitant hearing loss, and thus hearing rehabilitation should be considered preferentially for tinnitus management in this age group. Subjective tinnitus severity, depressive symptoms, and the stress levels were similar between the younger and older tinnitus patients. Therefore, treatment could be planned based upon the comprehensive understanding of the tinnitus characteristics and psychological aspects in each patient irrespective of age.

Older Australians' views about the impact of ageing on their nutritional practices: findings from a qualitative study.

PubMed

Brownie, Sonya

2013-06-01

To explore older people's views about how getting older has influenced their dietary practices. Focus groups with independently living residents aged 60 years and older in northern NSW, Australia. An inductive approach to thematic analysis was used. Five focus groups (n= 29) were conducted. The majority of participants were women (79%), mean age 73 years. The main findings were that reduced ability to eat large meals; health maintenance and disease management; food messages; food taste and convenience; and living arrangements appear to impact food choices and eating behaviour in this sample. In the presence of reduced and/or modified food intake, older people might benefit from an understanding of the concept of nutrient density in order to help them attain and maintain nutritional adequacy. Lifelong exposure to food messages (sometimes conflicting) resulted in many participants feeling confused about appropriate dietary practices for this age group. © 2012 The Author; Australasian Journal on Ageing © 2012 ACOTA.

Age has been suggested as a negative prognostic factor for hip arthroscopy. The purpose of this study was to compare patient characteristics and outcomes after hip arthroscopy in patients aged 50 years or older with a matched control group of patients aged 30 years or younger at a minimum postoperative follow-up of 2 years. Between September 2008 and March 2010, data were prospectively collected on all patients aged 50 years or older undergoing primary hip arthroscopy. Fifty-two patients met our inclusion and matching criteria, of whom all 52 (100%) were available for follow-up at a minimum of 2 years. This cohort was compared with a matched-pair control group of patients aged 30 years or younger who underwent similar procedures. The mean age of the study group was 54.8 years (range, 50 to 69 years), and that of the control group was 20.3 years (range, 13 to 30 years). The groups were matched at a 1:1 ratio, including 18 male patients (34.6%) and 34 female patients (65.4%) in each group, with a mean follow-up period of 32 months (range, 24 to 54 months). In the younger control group, the score improvement from preoperatively to 2 years' follow-up was 62.9 to 84.2 for the modified Harris Hip Score, 60.5 to 84.2 for the Non-Arthritic Hip Score, 63.1 to 86.5 for the Hip Outcome Score-Activities of Daily Living, and 42.2 to 72.7 for the Hip Outcome Score-Sport-Specific Subscale. In the older study group, the score improvement from preoperatively to 2 years' follow-up was 61.2 to 82.2 for the modified Harris Hip Score, 59.9 to 80.4 for the Non-Arthritic Hip Score, 63.9 to 83 for the Hip Outcome Score-Activities of Daily Living, and 41.2 to 64.6 for the Hip Outcome Score-Sport-Specific Subscale. All improvements in both groups were statistically significant at the 2-year postoperative follow-up (P < .001). There was no significant difference for all patient-reported outcome (PRO) scores at final follow-up between both groups. When we compared the change in PRO scores (Δ) from preoperatively to 2 years postoperatively, there was no significant difference between both groups. The overall survivorship rate was 98.1% for the younger control group and 82.7% for the older study group. Survivors aged 50 years or older show similar improvement to patients aged 30 years or younger in PRO and patient satisfaction scores. The 2-year survivorship rate was 98.1% for the younger control group and 82.7% for the older study group. Therefore we believe that hip arthroscopy should be considered a valid treatment option when treating hip pain in patients aged 50 years or older with a Tönnis arthritic grade of 0 or 1. Older patients should be counseled on the possibility of later conversion to total hip arthroplasty. Future work may include development of a decision-making tool to assess for prognosis to better delineate the indications for hip arthroscopy in the older population.

Good news about the effects of bad old-age stereotypes.

PubMed

Pinquart, Martin

2002-01-01

The study investigates whether the confrontation with negative, age-stereotyped information leads to a deterioration of older adults' self-perceptions as suggested by the labeling theory, or whether older adults protect their self-perceptions against deterioration as suggested by theories of the resilience of the aging self. Self perceptions, as well as peer-perception of other older adults in general were assessed in a pre-post design. In the experimental group, 60 older adults received negative information about competence in old age. The control group of 40 older adults received neutral information. In the experimental condition, the general perceptions of other older adults worsened whereas their self-perception improved. In the control condition, only small changes emerged. Furthermore, the change of self-perceptions varied by the perceived applicability of the negative information for oneself. We conclude that older adults use negative age stereotypes more as a standard of reference for downward comparison rather than integrating them into their self-perceptions.

Cognitive behaviour therapy for generalized anxiety disorder: Is CBT equally efficacious in adults of working age and older adults?

The current meta-analysis compared the efficacy of CBT for GAD between adults of working age and older people. In addition, we conducted a qualitative content analysis of treatment protocols used in studies with older clients to explore potential factors that may enhance treatment outcomes with this particular client group. Applying the inclusion criteria resulted in the identification of 15 studies with 22 comparisons between CBT and control groups (770 patients). When examining overall effect sizes for CBT for GAD between older people and adults of working age there were no statistically significant differences in outcome. However, overall effect size of CBT for GAD was moderate for older people (g=0.55, 95% CI 0.22-0.88) and large for adults of working age (g=0.94, 95% CI 0.52-1.36), suggesting that there is still room for improvement in CBT with older people. The main difference in outcome between CBT for GAD between the two age groups was related to methodological quality in that no older people studies used an intention-to-treat design. The content analysis demonstrated that studies with older clients were conducted according to robust CBT protocols but did not take account of gerontological evidence to make them more age-appropriate.

To analyze which abnormalities in body composition (obesity, sarcopenia or sarcopenic obesity) are related to reduced mobility in older people aged 80 years and older. The sample included 116 subjects aged 80 years and older. The body composition was measured using dual-energy X-ray absorptiometry (DXA) and mobility was assessed by motor tests. The χ2 test was used to analyze the proportion of older people with sarcopenia, obesity and sarcopenic obesity based on sex as well as to indicate an association between obesity, sarcopenia, sarcopenic obesity and mobility. Binary logistic regression, adjusted for the variables (sex and osteoarticular diseases), was used to express the magnitude of these associations. One-way analysis of variance was used to compare the mobility of four groups (Normal, Obesity, Sarcopenia and Sarcopenic Obesity). The Sarcopenia Group had lower performance in the lower limbs strength test and in sum of two tests compared with Obesity and Normal Groups. Older people with sarcopenia had higher chance of reduced mobility (OR: 3.44; 95%CI: 1.12-10.52). Older people aged 80 years and older with sarcopenia have more chance for reduction in mobility.

Spatial-Sequential Working Memory in Younger and Older Adults: Age Predicts Backward Recall Performance within Both Age Groups

Brown, Louise A.

2016-01-01

Working memory is vulnerable to age-related decline, but there is debate regarding the age-sensitivity of different forms of spatial-sequential working memory task, depending on their passive or active nature. The functional architecture of spatial working memory was therefore explored in younger (18–40 years) and older (64–85 years) adults, using passive and active recall tasks. Spatial working memory was assessed using a modified version of the Spatial Span subtest of the Wechsler Memory Scale – Third Edition (WMS-III; Wechsler, 1998). Across both age groups, the effects of interference (control, visual, or spatial), and recall type (forward and backward), were investigated. There was a clear effect of age group, with younger adults demonstrating a larger spatial working memory capacity than the older adults overall. There was also a specific effect of interference, with the spatial interference task (spatial tapping) reliably reducing performance relative to both the control and visual interference (dynamic visual noise) conditions in both age groups and both recall types. This suggests that younger and older adults have similar dependence upon active spatial rehearsal, and that both forward and backward recall require this processing capacity. Linear regression analyses were then carried out within each age group, to assess the predictors of performance in each recall format (forward and backward). Specifically the backward recall task was significantly predicted by age, within both the younger and older adult groups. This finding supports previous literature showing lifespan linear declines in spatial-sequential working memory, and in working memory tasks from other domains, but contrasts with previous evidence that backward spatial span is no more sensitive to aging than forward span. The study suggests that backward spatial span is indeed more processing-intensive than forward span, even when both tasks include a retention period, and that age predicts backward spatial span performance across the adult lifespan, within both younger and older adulthood.

We investigated young-old differences in emotion recognition using music and face stimuli and tested explanatory hypotheses regarding older adults' typically worse emotion recognition. In Experiment 1, young and older adults labeled emotions in an established set of faces, and in classical piano stimuli that we pilot-tested on other young and older adults. Older adults were worse at detecting anger, sadness, fear, and happiness in music. Performance on the music and face emotion tasks was not correlated for either age group. Because musical expressions of fear were not equated for age groups in the pilot study of Experiment 1, we conducted a second experiment in which we created a novel set of music stimuli that included more accessible musical styles, and which we again pilot-tested on young and older adults. In this pilot study, all musical emotions were identified similarly by young and older adults. In Experiment 2, participants also made age estimations in another set of faces to examine whether potential relations between the face and music emotion tasks would be shared with the age estimation task. Older adults did worse in each of the tasks, and had specific difficulty recognizing happy, sad, peaceful, angry, and fearful music clips. Older adults' difficulties in each of the 3 tasks-music emotion, face emotion, and face age-were not correlated with each other. General cognitive decline did not appear to explain our results as increasing age predicted emotion performance even after fluid IQ was controlled for within the older adult group.

This study investigated the influences of knowledge, particularly Internet, Web browser, and search engine knowledge, as well as cognitive abilities on older adult information seeking on the Internet. The emphasis on aspects of cognition was informed by a modeling framework of search engine information-seeking behavior. Participants from two older age groups were recruited: twenty people in a younger-old group (ages 60–70) and twenty people in an older-old group (ages 71–85). Ten younger adults (ages 18–39) served as a comparison group. All participants had at least some Internet search experience. The experimental task consisted of six realistic search problems, all involving information related to health and well-being and which varied in degree of complexity. The results indicated that though necessary, Internet-related knowledge was not sufficient in explaining information-seeking performance, and suggested that a combination of both knowledge and key cognitive abilities is important for successful information seeking. In addition, the cognitive abilities that were found to be critical for task performance depended on the search problem’s complexity. Also, significant differences in task performance between the younger and the two older age groups were found on complex, but not on simple problems. Overall, the results from this study have implications for instructing older adults on Internet information seeking and for the design of Web sites. PMID:20011130

Cultural frames, qualities of life, and the aging self.

We used the Self-Concept Enhancement Tactician (SCENT) model to explore whether older Norwegians and Canadians would tactically self-enhance on qualities considered significant within their cultures in their self-perceptions of aging. Qualities were measured using the WHOQOL-BREF and WHOQOL-OLD. Self-perceptions of aging were measured by the Attitudes to Aging Questionnaire. The study is a secondary analysis of data collected in a larger study; 393 older Norwegians and 202 older Canadians were included. The Norwegian and Canadian group self-enhanced their perceptions of psychosocial loss based on harmonious social relationships and being part of a larger social group. For self-perceptions of physical change, both groups self-enhanced on being self-sufficient and being part of a larger social group. Our findings suggest that Norwegians and Canadians are not highly individualistic people and also provide evidence of a bicultural self-perception of aging. Nurses should consider how cultural and individual perspectives affect the care priorities of older people.

Interactions between stereotype threat, subjective aging, and memory in older adults.

Marquet, Manon; Missotten, Pierre; Dardenne, Benoit; Adam, Stéphane

2017-12-08

This study examined whether the effects of stereotype threat on memory and subjective age were moderated by positive age stereotypes and self-perceptions of aging among older adults. Perceived threat as a mechanism underlying these effects was also explored. Results showed that stereotype threat (high vs. low threat) did not affect the dependent variables. Moreover, self-perceptions of aging did not moderate the effect of stereotype threat on the dependent variables. However, for people with more positive age stereotypes, older people under highthreat perceived more threat than people under low threat. This could be explained by an effect of age stereotypes in the high-threat group: the more positive age stereotypes held by participants, the more they perceived threat, which in turn decreased their memory performance and made them feel mentally older. We hypothesized that age group identity is stronger in people with more positive age stereotypes, which increase perceived threat.

Aging and fear of crime: an experimental approach to an apparent paradox.

PubMed

Ziegler, Raphael; Mitchell, David B

2003-01-01

Many fear of crime studies have revealed an interesting paradox: Although older adults are less likely to be victims, they report a higher fear of crime than younger adults. In this study, we experimentally manipulated vicarious exposure to crime. Younger (ages 18-29) and older adults (ages 61-78) were randomly assigned to view either a vivid video reenactment of a violent crime or a crime report newscast. Subjects in the violent video condition demonstrated significantly higher fear than did control group participants, but this effect was reliable only for younger adults. The older adults appeared to be unfazed by the violent video, and reported significantly less fear than the younger group. This could not be explained away on the basis of age group differences in neighborhood crime rates, victimization experience, or media exposure. Thus, when greater fear of crime is found in older adults, "old age" per se is not the cause.

To assess the retention rate of TNF antagonists in elderly patients suffering from chronic arthropathies and to identify predictive variables of discontinuation by inefficacy or by adverse events (AEs). All patients treated with TNF antagonists in BIOBADASER 2.0, with a diagnosis of either RA or spondyloarthritis (SpA: AS and PsA) were included and classified as <65 (younger) or ≥65 years of age (older) at start of the treatment. Cumulative incidence function for discontinuation (inefficacy or AE) was estimated as being the alternative reason for a competing risk. Competing-risks regression models were used to measure the association between study groups, covariates and reason for discontinuation. A total of 4851 patients were studied; 2957 RA (2291 in the younger group and 666 in the older group) and 1894 SpA (1795 in the younger group and 99 in the older group). Retention curves were statistically differently stratified by age groups, with the SpA younger group having the largest retention rate. Competing-risks regression models showed that in the older group, AEs were the most common reason for discontinuation regardless of the diagnosis of the patient and TNF antagonist molecule, whereas in the younger group, the most common cause of discontinuation was inefficacy. In conclusion, factors predicting discontinuation of TNF antagonists due to AEs are older age and diagnosis of RA. On the other hand, younger age predicts discontinuation due to lack of efficacy.

OLDER ADULTS CATCH UP TO YOUNGER ADULTS ON A LEARNING AND MEMORY TASK THAT INVOLVES COLLABORATIVE SOCIAL INTERACTION

Learning and memory abilities tend to decline as people age. The current study examines the question of whether a learning situation that emphasizes collaborative social interaction might help older persons overcome age-related learning and memory changes and thus perform similarly to younger persons. Younger and Older participants (n = 34 in each group) completed the Barrier Task, a game-like social interaction where partners work together to develop labels for a set of abstract tangrams. Participants were also administered standard clinical neuropsychological measures of memory, on which the Older group showed expected inferiority to the Younger group. On the Barrier Task, the Older group performed less well than the Younger group early on, but as the task progressed, the performance of the Older group caught up and became statistically indistinguishable from that of the Younger group. These results can be taken to suggest that a learning milieu characterized by collaborative social interaction can attenuate some of the typical memory disadvantages associated with being older.

Globally, suicide rates increase with age, being highest in older adults. This study analyzed differences in suicides in older adults (65 years and over) compared to middle-aged adults (35-64 years) in Queensland, Australia, during the years 2000-2012. The Queensland Suicide Register was utilized for the analysis. Annual suicide rates were calculated by gender and age group, and odds ratios with 95% confidence intervals were examined. In Queensland, the average annual rate of suicides for older adults was 15.27 per 100,000 persons compared to 18.77 in middle-aged adults in 2000-2012. There were no significant changes in time trends for older adults in 2002-2012. Suicide methods differed between gender and age groups. Older adults who died by suicide were more likely to be male, widowed, living alone or in a nursing home, and out of the work force. The prevalence of untreated psychiatric conditions, diagnosed psychiatric disorders, and consultations with a mental health professional three months prior to death was lower in older adults than middle-aged adults. Somatic illness, bereavement, and attention to suicide in the media were more common among older adults than middle-age adults. Older females were particularly more likely to pay attention to suicide in the media. Our findings show older adults who died by suicide were more likely to experience somatic illnesses, bereavement, and pay attention to suicide in the media compared to middle aged. Preventing suicide in older adults would therefore require holistic and comprehensive approaches.

To compare the efficacy and safety of canagliflozin, a sodium glucose co-transporter 2 inhibitor developed to treat type 2 diabetes mellitus (T2DM), in individuals younger than 75 and those aged 75 and older. Randomized Phase 3 studies. International study centers. Adults with T2DM. Changes from baseline in glycosylated hemoglobin (HbA1c ), fasting plasma glucose (FPG), blood pressure (BP), and body weight were measured. Efficacy was evaluated using pooled data from six randomized, double-blind, placebo-controlled studies (N = 4,158; n = 3,975 aged <75, n = 183 aged ≥75). Safety was assessed based on adverse event (AE) reports from eight randomized, double-blind, placebo- and active-controlled studies (N = 9,439; n = 8,949 aged <75, n = 490 aged ≥75). Canagliflozin 100 and 300 mg were associated with placebo-subtracted mean reductions in HbA1c in participants younger than 75 (-0.69% and -0.85%, respectively) and aged 75 and older (-0.65% and -0.55%, respectively). Dose-related reductions in FPG, body weight, and BP were seen with canagliflozin 100 and 300 mg in participants in both age groups. Overall AE incidence was 67.1% with canagliflozin 100 mg, 68.6% with canagliflozin 300 mg, and 65.9% with non-canagliflozin (pooled group of comparators in all studies) in participants younger than 75, and 72.4%, 79.1%, and 72.3%, respectively, in those aged 75 and older, with a similar safety profile in both groups. The incidence of volume depletion-related AEs was 2.2%, 3.1%, and 1.4% in participants younger than 75 with canagliflozin 100 and 300 mg and non-canagliflozin, respectively, and 4.9%, 8.7%, and 2.6%, respectively, in those aged 75 and older. Canagliflozin improved glycemic control, body weight, and BP in participants aged 75 and older. The overall incidence of AEs was high across treatment groups in participants aged 75 and older and higher than in those younger than 75. The safety profile of canagliflozin was generally similar in both age groups, with a higher incidence of AEs related to volume depletion observed with canagliflozin in participants aged 75 and older than in those younger than 75. These findings support canagliflozin, starting with the 100-mg dose, as an effective therapeutic option for older adults with T2DM. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

Contextualizing Psychosocial Determinants of Alcohol Use by Age Cohorts of Adults Living With HIV, Ages 50 and Older.

PubMed

Mannes, Zachary L; Burrell, Larry E; Dunne, Eugene M; Hearn, Lauren E; Whitehead, Nicole Ennis

We examined the influence of age on associations between affective states, social support, and alcohol use by age cohorts. We recruited 96 older Black adults living with HIV from the southeastern United States in 2013 and 2014. Participants completed questionnaires assessing demographics, psychological function, and substance use. Hierarchical regression analyses assessed the relationship between psychosocial factors and alcohol use in a 50- to 59-year-old group, and a 60-years-and-older age group. After controlling for covariates, trait anger, state anger, and life stress were positively associated with alcohol consumption in the younger group, while social support was negatively associated with alcohol consumption in the older group. Interventions should target negative affective states in 50- to 59-year-old adults with HIV, and preserve social support for adults with HIV as they age, as such interventions will likely have an impact on these individuals' alcohol consumption and longstanding quality of life.

Aging has long been regarded as one of the most critical factors affecting crash injury outcomes. In South Korea, where the elderly population is projected to reach 35.9% by 2050, the implications of an increasing number of elderly vehicle users on road safety are evident. In this research, the confounding effect of occupant age in a vehicle in terms of seat position and seatbelt use was investigated. In addition, elderly occupants were divided into a younger-old group aged between 65 and 74 years and an older-old group aged 75 years and older in an effort to assess whether the conventional elderly age standard of 65 years should be reconsidered. A multinomial logit framework was adopted to predict two-level injury severity using collision data between 2008 and 2015. Predictor variables included gender, age group, seat position, seatbelt, road type, road slope, road surface, road line, and type of vehicle. Five models, a base model with no interactions and four interaction models which were combinations of age group, seatbelt use and seat position, were devised and evaluated. With no interacting term, age was the most prominent predictor. Elderly occupants were most likely to suffer from severe injury without a seatbelt in all seat positions, and the use of a seatbelt reduced this likelihood the most in the elderly group as well. Front passenger seats had the highest risk to elderly occupants, while the driver seat was statistically insignificant. When the elderly group was divided into the younger-old group and the older-old group, the older-olds were found to be much more vulnerable compared to the younger-olds. In particular, older drivers were five times more likely to suffer a severe injury without a seatbelt. The degree of injury severity of elderly occupants was reduced the most with the use of a seatbelt, demonstrating the importance of using seat restraints. The sharp increase in the risk of injury of the older-old group suggests that the age standard of 65 years as the elderly group with regard to traffic safety may require reconsideration due to the growing number of elderly vehicle users on the road. Our results provide practical evidence with which to formulate new safety policies, including mandatory seatbelt use, driving age limits and insurance pricing.

The shortage of donor organs has led to increasing use of extended criteria donors, including older donors. The upper limit of donor age that produces acceptable outcomes continues to be explored. In liver transplantation, with appropriate selection, graft survival and patient outcomes would be comparable regardless of age. We performed a retrospective analysis of 1,036 adult orthotopic liver transplantations (OLT) from a prospectively maintained database performed between January 1, 2000 and December 31, 2013. The study focus group was liver transplantations performed using grafts from older (older than 60 years) deceased donors. Deceased donor liver transplantations done during the same time period using grafts from younger donors (younger than 60 years) were analyzed for comparison. Both groups were further divided based on recipient age (less than 60 years and 60 years or older). Donor age was the primary variable. Recipient variables included were demographics, indication for transplantation, Model for End-Stage Liver Disease (MELD), graft survival, and patient survival. Operative details and postoperative complications were analyzed. Patient demographics and perioperative details were similar between groups. Patient and graft survival rates were similar in the 4 groups. Rates of rejection (p = 0.07), bile leak (p = 0.17), and hepatic artery thrombosis were comparable across all groups (p = 0.84). Hepatitis C virus recurrence was similar across all groups (p = 0.10). Thirty-one young recipients (less than 60 years) received grafts from donors aged 70 or older. Their survival and other complication rates were comparable to those in the young donor to young recipient group. Comparable outcomes in graft and patient survivals were achieved using older donors (60 years or more), regardless of recipient age, without increased rate of complications.

To evaluate relationships among physician and cancer patient survival estimates, patients' perceived quality of life, care preferences, and outcomes, and how they vary across middle-aged and older patient groups. Subjects were from the Study to Understand Prognoses and Preferences for Risks of Treatments (SUPPORT) prospective cohort studied in five US teaching hospitals (from 1989 to 1994), and included 720 middle-aged (45 to 64 years) and 696 older (> or = 65 years) patients receiving care for advanced cancer. Perspectives were assessed in physician and patient/surrogate interviews; care practices and outcomes were determined from hospital records and the National Death Index. General linear models were used within age groups to obtain adjusted estimates. Although most patients had treatment goals to relieve pain, treatment preferences and care practices were linked only in the older group. For older patients, preference for life-extending treatment was associated with more therapeutic interventions and more documented discussions; cardiopulmonary resuscitation (CPR) preference was linked to more therapeutic interventions and longer survival. For middle-aged patients, better perceived quality of life was associated with preferring CPR. In both groups, patients' higher survival estimates were associated with preferences for life-prolonging treatment and CPR; physicians' higher survival estimates were associated with patients' preferences for CPR, fewer documented treatment limitation discussions about care, and actual 6-month survival. More discussions were associated with readmissions and earlier death. More aggressive care was not related to outcomes. Fewer older patients preferred CPR or life-prolonging treatments. Although older patients' goals for aggressive treatment were related to care, this was not so for middle-aged patients. Aggressive care was not related to prolonged life in either group.

Older medical students' performances at McGill University.

To compare admission data and academic performances of medical students younger and older than 25, and to qualify older students' experiences and perceptions in medical school. The authors reviewed 1988-1991 data for applications to the McGill University Faculty of Medicine. Data included GPAs and MCAT scores, as well as ratings for reference letters, autobiographical statements, and interviews. For those same years, the authors measured students' academic performances in the preclinical and clinical years. The authors compared the data by students' age: "younger" students, aged 17 to 24; and "older" students, aged 25 and above. All enrolled students took the Derogatis Stress Profile, and the older students participated in focus groups. The older applicants had lower GPAs and MCAT scores, but higher interview and reference letter ratings. For older accepted students, basic science course scores were lower than those of younger students, but clinical scores did not differ significantly between the groups. The two groups had similar stress levels, although older students tested lower in driven behavior, relaxation potential, attitude posture, and hostility. In focus groups, the older students spoke of learning style differences, loss of social support, and loss of professional identity. Different scores in admission criteria suggest that McGill uses different standards to select older medical students. Older students admitted under different criteria, however, do just as well as do younger students by their clinical years. A broad-based study of admission criteria and outcomes for the older student population is warranted.

The relationship between aging and practice effects on longitudinal neuropsychological assessments was investigated in middle-aged and older people with schizophrenia and healthy controls. Older people with schizophrenia (n = 107; M age = 56.1) and age-comparable nonpsychiatric controls (n = 107; M age = 57.7) were scheduled to receive annual assessments on a comprehensive battery of neuropsychological tests for an average of 2.5 years (range 11 months to 4 years). Mixed-model analyses were used to separately examine the effects of practice and age on test performance. Number of prior assessments (practice) was associated with significant performance improvement across assessments, whereas older age was associated with significant decline in performance. The groups did not differ significantly in extent of age-related cognitive decline, but a three-way interaction among group, age, and practice was found, such that greater age-related decline in practice effects were found for older people with schizophrenia relative to nonpsychiatric participants. This study did not find any evidence of neurodegenerative age-related decline in neuropsychological abilities in middle-aged and older people with schizophrenia, but older age was associated with diminished ability to benefit from repeated exposure to cognitive tasks in people with schizophrenia. Cognitive impairment in schizophrenia may combine with cognitive decline associated with normal aging to reduce practice effects in older patients. These findings have important implications for the design of studies examining the longitudinal trajectory of cognitive functioning across the life span of people with schizophrenia, as well as clinical trials that attempt to demonstrate cognitive enhancement in these individuals.

To assess smoking prevalence before and after the rise in legal age of sale of cigarettes in England and Wales from age 16 to age 18 in October 2007. A series of monthly cross-sectional household surveys: the 'Smoking Toolkit Study'. England. A total of 53, 322 adults aged 16 and over interviewed between October 2006 and May 2009, 1136 of whom were aged 16 or 17 years. Change in smoking prevalence from pre- to post-legislation, assessed by self-reported smoking status, among the 16-17-year-old group and older adults. The prevalence change following the legislation among those aged 16 and 17 was 7.1 percentage points (denominator=1136) compared with 2.4 percentage points (denominator=52,186) for older adults (odds ratio 1.36, P=0.024, 95% confidence interval=1.04-1.77 for the interaction). There was no difference within older age categories. There was a greater fall in prevalence in 16-17-year-olds following an increase in age of sale than in older age groups. This provides some support to the view that raising the age of sale can, at least in some circumstances, reduce smoking prevalence in younger age groups. © 2010 The Authors.

Destination memory, a memory component allowing the attribution of information to its appropriate receiver (e.g., to whom did I lend my pen?), is compromised in normal aging. The present paper investigated whether older adults might show better memory for older destinations than for younger destinations. This hypothesis is based on empirical research showing better memory for older faces than for younger faces in older adults. Forty-one older adults and 44 younger adults were asked to tell proverbs to older and younger destinations (i.e., coloured faces). On a later recognition test, participants had to decide whether they had previously told some proverb to an older/younger destination or not. Prior to this task, participants reported their frequency of contact with other-age groups. The results showed lower destination memory in older adults than in younger adults. Interestingly, older adults displayed better memory for older than for younger destinations. The opposite pattern was seen in younger adults. The low memory for younger destinations, as observed in older adults, was significantly correlated with limited exposure to younger individuals. These findings suggest that for older adults, the social experience can play a crucial role in the destination memory, at least as far as exposure to other-age groups is concerned.

The 2010 Global Burden of Disease estimates show that 57% of all TB deaths globally occurred among adults older than 50 years of age. Few studies document the TB burden among older adults in Southern Africa. We focused on adults older than 55 years to assess the relative TB burden and associated demographic factors. A cross sectional nationally representative TB prevalence survey conducted of Zambian residents aged 15 years and above from 66 clusters across all the 10 provinces of Zambia. Evaluation included testing for TB as well as an in-depth questionnaire. We compared survey data for those aged 55 and older to those aged 15-54 years. Survey results were also compared with 2013 routinely collected programmatic notification data to generate future hypotheses regarding active and passive case finding. Among older adults with TB, 30/ 54 (55.6%) were male, 3/27 (11.1%) were HIV infected and 35/54 (64.8%) lived in rural areas. TB prevalence was higher in those aged ≥55 (0.7%) than in the 15-54 age group (0.5%). Males had higher rates of TB across both age groups with 0.7% (15-54) and 1.0% (≥55) compared with females 0.4% (15-54) and 0.6% (≥55). In rural areas, the prevalence of TB was significantly higher among older than younger adults (0.7% vs 0.3%), while the HIV infection rate was among TB patients was lower (11.1% vs 30.8%). The prevalence survey detected TB in 54/7484 (0.7%) of older adults compared to 3619/723,000 (0.5%) reported in 2013 programmatic data. High TB rates among older adults in TB endemic areas justify consideration of active TB case finding and prevention strategies.

Previous studies of theory of mind (ToM) in old age have provided mixed results. We predicted that educational level and cognitive processing are two factors influencing the pattern of the aging of ToM. To test this hypothesis, a younger group who received higher education (mean age 20.46 years), an older group with an education level equal to that of the young group (mean age 76.29 years), and an older group with less education (mean age 73.52 years) were recruited. ToM tasks included the following tests: the second-order false-belief task, the faux-pas task, the eyes test, and tests of fundamental aspects of cognitive function that included two background tests (memory span and processing speed) and three subcomponents of executive function (inhibition, updating, and shifting). We found that the younger group and the older group with equally high education outperformed the older group with less education in false-belief and faux-pas tasks. However, there was no significant difference between the two former groups. The three groups of participants performed equivalently in the eyes test as well as in control tasks (false-belief control question, faux-pas control question, faux-pas control story, and Eyes Test control task). The younger group outperformed the other two groups in the cognitive processing tasks. Mediation analyses showed that difficulties in inhibition, memory span, and processing speed mediated the age differences in false-belief reasoning. Also, the variables of inhibition, updating, memory span, and processing speed mediated age-related variance in faux-pas. Discussion focused on the links between ToM aging, educational level, and cognitive processing.

Risk factors for medically unexplained falls may include reduced muscle power, strength and asymmetry in the lower limbs. Conflicting reports exist about strength and there is little information about power and symmetry. Forty-four healthy young people (29.3 +/- 0.6 years), 44 older non-fallers (75.9 +/- 0.6 years), and 34 older fallers (76.4 +/- 0.8 years) were studied. Isometric, concentric and eccentric strength of the knee and ankle muscles and leg extension power were measured bilaterally. The younger group was stronger in all muscles and types of contraction than both older groups (P < 0.02-0.0001). Strength differences between the older groups occasionally reached significance in individual muscles and types of contraction but overall the fallers had 85% of the strength and 79% of the power of the non-fallers (P < 0.001). Young subjects generated more power than both older groups (P < 0.0001) and the fallers generated less than the non-fallers (P = 0.03). Strength symmetry showed an inconsistent age effect in some muscles and some contraction types. This was similar overall in the two older groups. Both older groups had greater asymmetry in power than the young (P < 0.02-0.004). Power asymmetry tended to be greater in the fallers than the non-fallers but this did not reach significance. These data do not support the suggestion that asymmetry of strength and power are associated with either increasing age or fall history. Power output showed clear differences between age groups and fall status and appears to be the most relevant measurement of fall risk and highlights the cumulative effects on function of small changes in strength in individual muscle groups.

We report the bone attenuation of ankle joint measured on computed tomography (CT) and the cause of injury in patients with ankle fractures. The results showed age- and gender-dependent low bone attenuation and low-energy trauma in elderly females, which suggest the osteoporotic features of ankle fractures. This study was performed to investigate the osteoporotic features of ankle fracture in terms of bone attenuation and cause of injury. One hundred ninety-four patients (mean age 51.0 years, standard deviation 15.8 years; 98 males and 96 females) with ankle fracture were included. All patients underwent CT examination, and causes of injury (high/low-energy trauma) were recorded. Mean bone attenuations of the talus, medial malleolus, lateral malleolus, and distal tibial metaphysis were measured on CT images. Patients were divided into younger age (<50 years) and older age (≥50 years) groups, and mean bone attenuation and causes of injury were compared between the two groups in each gender. Proportion of low-energy trauma was higher in the older age group than in the younger age group, but the difference was only significant in female gender (p = 0.011). The older age group showed significantly lower bone attenuation in the talus, medial malleolus, lateral malleolus, and distal tibial metaphysis than the younger age group in both genders. The older age group showed more complex pattern of fractures than the younger age group. With increasing age, bone attenuations tended to decrease and the difference of bone attenuation between the genders tended to increase in the talus, medial malleolus, lateral malleolus, and distal tibial metaphysis. Ankle fracture had features of osteoporotic fracture that is characterized by age- and gender-dependent low bone attenuation. Ankle fracture should not be excluded from the clinical and research interest as well as from the benefit of osteoporosis management.

Objective We examined trends from 1991–2009 in total energy intake and food group intake, and examine whether shifts varied by age or generation. Design Longitudinal time series (1991, 1993, 1997, 2000, 2004, 2006, 2009) Setting Nine provinces in China Participants Older Chinese aged ≥60 years (n=5,068) from the China Health and Nutrition Survey from 1991–2009 Methods Using three 24-hour recalls and a household food inventory collected over three consecutive days, the top twenty food group contributors to total energy intake from 1991–2009 were identified, and the mean kilocalorie (kcal) difference between 1991 and 2009 for each food group was ranked. The top twenty food group contributors to total energy intake from 1991–2009 were identified, and the mean kilocalorie (kcal) difference between 1991 and 2009 for each food group was ranked. Linear regression was used to examine changes in mean calorie intake of food groups between 1991 and 2009, adjusting for age, sex, and region. In addition, we examined changes in the mean kcal per capita intake to examine shifts by age group and generation. Results Mean total energy intake increased significantly among older Chinese adults from 1379 total kilocalories in 1991 to 1463 kilocalories in 2009 (p< 0.001). Most food groups showed a significant increase in intake from 1991 to 2009, with plant oil, wheat buns, and wheat noodles showing the greatest increase. At the same age, more recent generations had more energy intake than earlier generations. An aging effect was observed, with energy intake decreasing with age, although more recent generations showed a smaller decrease in energy intake with aging. Conclusion Older Chinese adults in recent generations show an increase in total calorie intake compared to older Chinese of earlier generations, paired with a less significant decrease in calorie intake as they age. Increased consumption of high-fat, non-staple high-carbohydrate foods such as plant oil and wheat buns suggests that diet quality of older Chinese adults is becoming less healthful in recent years.

Background The aim was to investigate the association between sleep disturbances and cognitive function in younger and older individuals from an ageing population. Methods 3,968 male and 4,821 female white participants, aged 50 years and over, from the English Longitudinal Study of Ageing (ELSA) were studied. Information on sleep quality and quantity as well as both amnestic (memory, ACF) and non-amnestic (non-memory, nACF) function was available at Wave 4 (2008). Analysis of covariance was used to evaluate the relationship between sleep and cognitive function. Results After adjustment for multiple confounders in the younger group (50–64 years) duration of sleep explained 15.2% of the variance in ACF (p = 0.003) and 20.6% of nACF (p = 0.010). In the older group (65+ years) the estimates were 21.3% (p<0.001) and 25.6% (p<0.001), respectively. For sleep quality, there was a statistically significant association between sleep quality and both ACF (p<0.001) and nACF (p<0.001) in the older age group, but not in the younger age group (p = 0.586 and p = 0.373, respectively; interaction between age and sleep quality in the study sample including both age groups: p<0.001 for ACF and p = 0.018 for nACF). Sleep quality explained between 15.1% and 25.5% of the variance in cognition. The interaction with age was independent of duration of sleep. At any level of sleep duration there was a steeper association between sleep quality and ACF in the older than the younger group. Conclusions The associations between sleep disturbances and cognitive function vary between younger and older adults. Prospective studies will determine the temporal relationships between sleep disturbances and changes in cognition in different age groups. PMID:24968354

Trunk repositioning errors are increased in balance-impaired older adults.

Goldberg, Allon; Hernandez, Manuel Enrique; Alexander, Neil B

Controlling the flexing trunk is critical in recovering from a loss of balance and avoiding a fall. To investigate the relationship between trunk control and balance in older adults, we measured trunk repositioning accuracy in young and balance-impaired and unimpaired older adults. Young adults (N = 8, mean age 24.3 years) and two groups of community-dwelling older adults defined by unipedal stance time (UST)-a balance-unimpaired group (UST > 30 seconds, N = 7, mean age 73.9 years) and a balance-impaired group (UST < 5 seconds, N = 8, mean age 79.6 years)-were tested in standing trunk control ability by reproducing a approximately 30 degrees trunk flexion angle under three visual-surface conditions: eyes opened and closed on the floor, and eyes opened on foam. Errors in reproducing the angle were defined as trunk repositioning errors (TREs). Clinical measures related to balance, trunk extensor strength, and self-reported disability were obtained. TREs were significantly greater in the balance-impaired group than in the other groups, even when controlling for trunk extensor strength and body mass. In older adults, there were significant correlations between TREs and three clinical measures of balance and fall risk, UST and maximum step length (-0.65 to -0.75), and Timed Up & Go score (0.55), and between TREs and age (0.63-0.76). In each group TREs were similar under the three visual-surface conditions. Test-retest reliability for TREs was good to excellent (intraclass correlation coefficients > or =0.74). Older balance-impaired adults have larger TREs, and thus poorer trunk control, than do balance-unimpaired older individuals. TREs are reliable and valid measures of underlying balance impairment in older adults, and may eventually prove to be useful in predicting the ability to recover from losses of balance and to avoid falls.

Benefits of having friends in older ages: differential effects of informal social activities on well-being in middle-aged and older adults.

It has been considered a fact that informal social activities promote well-being in old age, irrespective of whether they are performed with friends or family members. Fundamental differences in the relationship quality between family members (obligatory) and friends (voluntary), however, suggest differential effects on well-being. Further, age-related changes in networks suggest age-differential effects of social activities on well-being, as older adults cease emotionally detrimental relationships. Longitudinal representative national survey study with middle-aged (n = 2,830) and older adults (n = 2,032). Age-differential effects of activities with family members and friends on changes in life satisfaction, positive affect (PA), and negative affect (NA) were examined in latent change score models. In the middle-aged group, activities with friends and families increased PA and life satisfaction and were unrelated to NA. In the older age group, family activities increased both PA and NA and were unrelated to changes in life satisfaction, but activities with friends increased PA and life satisfaction and decreased NA. Social activities differentially affect different facets of well-being. These associations change with age. In older adults, the effects of social activities with friends may become more important and may act as a buffer against negative effects of aging.

The increasing number of older adults with blood-related disorders and the introduction of reduced intensity conditioning regimens has led to increases in hematopoietic stem cell (HSC) transplantation among older adults and a corresponding increase in the age of siblings who donate HSCs to these patients. Data regarding the donation-related experiences of older donors is lacking. The Related Donor Safety Study (RDSafe) aimed to examine/compare health-related quality of life (HRQoL) of older versus younger HSC donors. 60 peripheral blood stem cell (PBSC) donors ages 18–60 and 104 PBSC donors age >60 completed validated questionnaires at pre-donation, 4 weeks and 1 year post-donation. Prior to donation, older donors had poorer general physical health (t=−3.27; p=.001) but better mental health (t=2.11; p<.05). There were no age differences in multiple other donation-related factors. At 4 weeks post-donation, there were no group differences in general physical/mental health, but older donors were less likely to report donation-related pain (t=−2.26; p<.05) and concerns (t=−3.38; p=.001). At both 4 weeks and 1 year post-donation, there were no significant differences in the percentage of each age group feeling physically back to normal or in the number of days it took donors to feel completely well. There was no evidence that increasing age within the older donor group was associated with poorer donation-related HRQoL. Taken together, these data support the current practice of HSC donation by sibling donors above age 60, providing no evidence of worsening HRQoL up to one year after donation in individuals up to age 76.

This experiment investigated age differences in electrophysiological correlates of retrieval success in a word-stem cued recall task. Young adults (M+/-SD: 21.4 years+/-1.9) performed this memory task more accurately than older participants (M+/-SD: 65.1 years+/-3.3). Robust event-related brain potential (ERP) old/new effects were identified in both age groups. The main age differences were observed in latency and lateralization of ERP effects. Young adults exhibited a parietal effect that became focused over left parietal electrodes, whereas no asymmetry was observed in older adults. Moreover, ERP effects were more delayed in the older group. Overall, these findings provide some evidence of the reduction of processing speed during aging and suggest that young and older adults may recruit distinct cerebral patterns during episodic cued recall.

Improving the management of asthma in older adults.

PubMed

Carnegie, Elaine; Jones, Angela

Older people with asthma are a discrete patient group that requires specialist nursing skills and knowledge. They have specific and sometimes hidden needs that will affect their quality of life unless these are addressed by caring and competent nurses who have an interest in asthma. It is necessary to focus on both asthma and ageing to help older people achieve good asthma outcomes. This article discusses the complex physical, social and psychological issues affecting people with asthma aged 64 or older, age-related risk factors for poor control, age-related barriers to assessment and treatment, the scope of pharmacological and non-pharmacological approaches, and principal treatment outcomes. Providing high quality services and information will equip older people to manage their asthma more effectively, attain physical and mental wellbeing, and lead to fewer hospitalisations and fatal episodes in this group.

Visual impairment is the second most prevalent disability among older adults (National Center for Health Statistics, 1993), affecting about 2.9 million Americans aged 65 and older (Eye Diseases Prevalence Research Group, 2004). As the population ages, the number of individuals who will experience age-related vision loss will also increase.…

The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) has been extensively evaluated in groups of patients with osteoarthritis, yet not in patients with a femoral neck fracture. This study aimed to determine the reliability, construct validity, and responsiveness of the WOMAC compared with the Short Form-12 (SF-12) and the EuroQol 5D (EQ-5D) questionnaires for the assessment of elderly patients with a femoral neck fracture. Reliability was tested by assessing the Cronbach alpha. Construct validity was determined with the Pearson correlation coefficient. Change scores were calculated from ten weeks to twelve months of follow-up. Standardized response means and floor and ceiling effects were determined. Analyses were performed to compare the results for patients less than eighty years old with those for patients eighty years of age or older. The mean WOMAC total score was 89 points before the fracture in the younger patients and increased from 70 points at ten weeks to 81 points at two years postoperatively. In the older age group, these scores were 86, 75, and 78 points. The mean WOMAC pain scores before the fracture and at ten weeks and two years postoperatively were 92, 76, and 87 points, respectively, in the younger age group and 92, 84, and 93 points in the older age group. Function scores were 89, 68, and 79 points for the younger age group and 84, 71, and 73 points for the older age group. The Cronbach alpha for pain, stiffness, function, and the total scale ranged from 0.83 to 0.98 for the younger age group and from 0.79 to 0.97 for the older age group. Construct validity was good, with 82% and 79% of predefined hypotheses confirmed in the younger and older age groups, respectively. Responsiveness was moderate. No floor effects were found. Moderate to large ceiling effects were found for pain and stiffness scales at ten weeks and twelve months in younger patients (18% to 36%) and in the older age group (38% to 53%). The WOMAC showed good reliability, construct validity, and responsiveness in both age groups of elderly patients with a femoral neck fracture who had been physically and mentally fit before the fracture. The instrument is suitable for use in future clinical studies in these populations. The results are based on two clinical trials. The questionnaires used concern pure, clinically relevant issues (ability to walk, climb stairs, etc.). Moreover, the results can be used for future research comparing clinical outcomes (or treatments) for populations with a femoral neck fracture.

To assess the influence of age as an independent factor determining the prognosis and outcome of patients with acute myocardial infarction (AMI) treated using primary percutaneous coronary intervention (PCI). A retrospective analysis from a dedicated database. A high-volume interventional cardiology center in the Netherlands. Four thousand nine hundred thirty-three consecutive patients with AMI. Baseline characteristics and clinical outcomes after 30 days and 1 year were compared according to age categorized in three groups: younger than 65, 65 to 74, and 75 and older. A more-detailed analysis was performed with six age groups, from younger than 40 to 80 and older. Of the 4,933 consecutive patients with AMI treated with PCI between 1992 and 2004, 643 were aged 75 and older. Multivariate analysis revealed that patients aged 65 to 75 had a greater risk of 1-year mortality than those younger than 65 (adjusted odds ratio (AOR)=1.57, 95% confidence interval (CI)=1.15-2.16) and that those aged 75 and older had a greater risk of 1-year mortality than those younger than 65 (AOR=3.03, 95% CI=2.14-4.29). In this retrospective analysis, older age was independently associated with greater mortality after PCI for AMI. Patients aged 65 and older had a higher risk of mortality than younger patients, and those aged 75 and older had the highest risk of mortality.

The purpose of this study was to investigate the efficacy of intravitreal aflibercept for neovascular age-related macular degeneration (nAMD) in very elderly patients aged 90 years or older at 2 years after treatment initiation. In this multicentre retrospective data analysis from electronic medical record, consecutive treatment-naive patients with nAMD treated with aflibercept with at least 2 years follow-up were stratified into those aged < 90 years (Group I) and an older cohort aged 90 and over (Group II). We compared the visual acuity (EDTRS letters) outcomes at 4 weekly intervals between the two groups over a 2-year period. The mean visual acuity of Group I at presentation was 56.3 ETDRS letters versus 52.8 letters in Group II. Maximal visual acuity was achieved in both the groups by 6 months after initiating treatment (4.7 vs. 4.0 letters gain). By 2 years, the mean visual acuity of the older cohort fell marginally below their baseline visual acuity (0.8 letter loss), while Group I presented +2.1 letters gain. The number of injections given and the retention rate of the older cohort were no different to the rest of the patients. Very old patients with nAMD benefited from aflibercept, but not to the same degree as the younger patients. The study showed that, on an average, the very elderly patients were able to adhere to the intensive anti-VEGF treatment regimens.

Abdominal aortic aneurysm (AAA) is a widening of the aorta below the renal arteries with a diameter equal to or greater than 3 cm. The prevalence of AAA is estimated at 4-8% in men aged 65 years or older and 1-2% among women over 65 years old. Participation in screening programmes has decreased the number of aortic ruptures. All men aged 60 years and older, and women aged 65 years and older living in the rural/urban commune in central Poland were invited to participate in the study. In total 922 persons (61% of the invited population) entered the study. The men were divided into two groups: 60-64 years old, and 65 years and older. Screening abdomen ultrasound was performed and demographic data was collected. Among the 922 examined persons two (1.01%) AAAs were diagnosed in the group of men 60-64 years of age, three (0.82%) AAAs amongst women ≥ 65 years old, and 33 (9.29%) AAAs were found in the group of men aged 65 years and older. A positive relationship between the presence of AAA and smoking (p = 0.0048), age of men (p = 0.0009), and history of myocardial infarction/acute coronary syndrome (MI/ACS) (p = 0.0079) was found. There was no correlation between the frequency of AAA and diabetes mellitus (p = 0.46), hypertension (p = 0.38), and family history of AAA (p = 0.44). The prevalence of AAA in men aged 65 years and older is seemingly larger than in previously conducted studies, while among men 60-64 years of age and women aged ≥ 65 it is similar. Older age, smoking, and a history of MI/ACS were the most important risk factors of AAA occurrence.

Generational Differences in Internalized Transnegativity and Psychological Distress Among Feminine Spectrum Transgender People.

This study examined internalized transnegativity and psychological distress in two age groups of transgender individuals who identified their gender identity on the feminine spectrum (rather than congruent with their male sex assigned at birth). Due to greater visibility and acceptance of gender diversity in the United States, we hypothesized that internalized transnegativity would be lower in the younger compared with the older group, and that the younger generation would, therefore, report lower levels of psychological distress than the older generation. The study sample consisted of trans-feminine individuals (N = 440) who completed a online survey of the U.S. transgender population and comprised a younger group aged 18-24 years (n = 133) and an older group aged 40 years and older (n = 307). Internalized transnegativity was assessed using the Transgender Identity Survey, and psychological distress was assessed with the Brief Symptom Inventory 18. We used regression and mediation analysis to examine differences between the two groups. Contrary to our expectations, the older group reported significantly lower levels of both internalized transnegativity and psychological distress compared with the younger group. Internalized transnegativity partially mediated the relationship between age group and psychological distress. Despite greater visibility of transgender people and increasing acceptance of gender diversity in the United States, the younger trans-feminine individuals reported more psychological distress than the older transfeminine individuals, which was, in part, related to internalized transnegativity. Trans-feminine individuals may benefit from culturally sensitive and clinically competent mental health services to alleviate internalized transnegativity and psychological distress.

Self-referencing enhances recollection in both young and older adults

Processing information in relation to the self enhances subsequent item recognition in both young and older adults, and further, enhances recollection at least in the young. Because older adults experience recollection memory deficits it is unknown whether self-referencing improves recollection in older adults. We examined recollection benefits from self-referential encoding in older and younger adults and further examined the quality and quantity of episodic details facilitated by self-referencing. We further investigated the influence of valence on recollection given prior findings of age group differences in emotional memory (i.e. “positivity effects”). Across 2 experiments, young and older adults processed positive and negative adjectives either for self-relevance or for semantic meaning. We found that self-referencing, relative to semantic encoding, increased recollection memory in both age groups. In Experiment 1, both groups remembered proportionally more negative than positive items when adjectives were processed semantically; however, when adjectives were processed self-referentially, both groups exhibited evidence of better recollection for the positive items, inconsistent with a positivity effect in aging. In Experiment 2, both groups reported more episodic details associated with recollected items, as measured by a memory characteristic questionnaire (MCQ), for the self-reference relative to the semantic condition. Overall, these data suggest that self-referencing leads to detail-rich memory representations reflected in higher rates of recollection across age. PMID:25264018

Therapeutic effects of an indoor gardening programme for older people living in nursing homes.

To explore the activities of daily living and psychological well-being of older people living in nursing homes and also to examine the effectiveness of a gardening programme in enhancing socilaisation and life satisfaction, reducing loneliness and promoting activities of daily living for older people living in nursing homes. Life in nursing homes can mean very limited physical and social activity, leading to further decline in function for many older people. This was a quasi-experimental pre and posttest control group design. Older people from nursing homes were invited to join the eight week indoor gardening programme (experimental group), while older people in other nursing homes were treated as the control group; they received regular care without the eight week indoor gardening programme. There were 26 older people (25 female and one male; mean age 85 years) in the experimental group and 27 (20 female and seven male; mean age 82 years) in the control group. Demographic data including age, gender, educational level and financial situation were collected, in addition to information regarding life satisfaction, loneliness, physical activity and social network situation, before and after the eight week indoor gardening programme for both the experimental and control groups. Also, details of experimental group subjects' experience of the indoor gardening programme were elicited using open-ended questions. There were significant improvements in life satisfaction and social network and a significant decrease in perception of loneliness for older people in the experimental group after the eight week indoor gardening programme, while the activities of daily living were unchanged for both groups after the programme. Given the positive effects of gardening activities, it is suggested that they be promoted more widely among nursing home residents.

Muscle impairment is a common condition in older people and a powerful risk factor for disability and mortality. The aim of this study was to apply the European Working Group on Sarcopenia in Older People criteria to estimate the prevalence and investigate the clinical correlates of sarcopenia, in a sample of Italian community-dwelling older people. Cross-sectional analysis of 730 participants (74% aged 65 years and older) enrolled in the InCHIANTI study. Sarcopenia was defined according to the European Working Group on Sarcopenia in Older People criteria using bioimpedance analysis for muscle mass assessment. Logistic regression analysis was used to identify the factors independently associated with sarcopenia. Sarcopenia defined by the European Working Group on Sarcopenia in Older People criteria increased steeply with age (p < .001), with 31.6% of women and 17.4% of men aged 80 years or older being affected by this condition. Higher education (odds ratio: 0.85; 95% CI: 0.74-0.98), lower insulin-like growth factor I (lowest vs highest tertile, odds ratio: 3.89; 95% CI: 1.03-14.1), and low bioavailable testosterone (odds ratio: 2.67; 95% CI: 1.31-5.44) were independently associated with the likelihood of being sarcopenic. Nutritional intake, physical activity, and level of comorbidity were not associated with sarcopenia. Sarcopenia identified by the European Working Group on Sarcopenia in Older People criteria is a relatively common condition in Italian octogenarians, and its prevalence increases with aging. Correlates of sarcopenia identified in this study might suggest new approaches for prevention and treatment of sarcopenia.

Considering the importance of muscle strength to functional capacity in the elderly, the study investigated the effects of age on isokinetic performance and torque production as a function of muscle length. Eleven younger (24.2 ± 2.9 years) and 16 older men (62.7 ± 2.5 years) were subjected to concentric and eccentric isokinetic knee extension/flexion at 60 and 120° · s(-1) through a functional range of motion. The older group presented lower peak torque (in newton-meters) than the young group for both isokinetic contraction types (age effect, p < 0.001). Peak torque deficits in the older group were near 30 and 29% for concentric and eccentric contraction, respectively. Concentric peak torque was lower at 120° · s(-1) than at 60° · s(-1) for both groups (angular velocity effect, p < 0.001). Eccentric knee extension torque was the only exercise tested that showed an interaction effect between age and muscle length (p < 0.001), which suggested different torque responses to the muscle length between groups. Compared with the young group, the eccentric knee extension torque was 22-56% lower in the older group, with the deficits being lower in the shortened muscle length (22-27%) and higher (33-56%) in the stretched muscle length. In older men, the production of eccentric knee strength seems to be dependent on the muscle length. At more stretched positions, older subjects lose the capacity to generate eccentric knee extension torque. More studies are needed to assess the mechanisms involved in eccentric strength preservation with aging and its relationship with muscle length.

Introducing older people to the theory of gerotranscendence.

PubMed

Wadensten, Barbro

2005-11-01

This paper reports a study whose aims were to introduce the theory of gerotranscendence to a group of older people; to give participants in the group an opportunity to discuss their ageing process; to study how participants described their ageing in relation to the theory; and to gather participants' opinions about discussing their ageing in a group. The theory of gerotranscendence states that human development is a process extending into old age. Guidelines had previously been derived for its practical use in the care of older people, aiming to promote their development towards gerotranscendence. A qualitative descriptive approach was taken, and older people were invited to participate in group sessions at a day centre. At the sessions, participants discussed their ageing, and a video presentation about the theory of gerotranscendence was shown at one of the sessions. They were encouraged to discuss the description of the ageing process presented in the video and to link this to their own experiences of growing old. The discussion in each session was tape-recorded and transcribed verbatim. Data were analysed and categorized using qualitative methods. The data were collected in 2002. All women had an experience of ageing that was in some way in line with the theory's description, and they more or less agreed that this description of ageing was in accordance with their own ageing. They considered that it was interesting and fruitful to discuss ageing in a group. They felt that introduction of the view of ageing offered by the theory of gerotranscendence was beneficial because it gave them a more positive view of ageing which also allowed them to be as they were. It is possible to arrange this type of group activity for older people, resulting in possibilities to use aspects of the theory of gerotranscendence as an intervention in gerontological nursing.

public and patient involvement (PPI) in clinical research is increasingly advocated by funding and regulatory bodies. However, little is known about the views of either academics or members of the public about perceptions of the practical realities of PPI, particularly in relation to ageing research. to survey current levels of PPI in biomedical and clinical research relating to ageing at one institution. To compare and contrast the views of academics and the public about PPI relating to research about ageing. electronic survey of senior academics, postgraduate students and members of a local user group for older people. thirty-three academics (18 principal investigators and 15 PhD students) at a biomedical research institution. Fifty-four members of a local user group for older people. thirty per cent (10/33) of projects described some PPI activity. Older adults were more positive about active involvement in research about ageing than academics. The perceived benefits of and barriers to involvement in research were similar among all groups, although older members of the public were more likely than academics to acknowledge potential barriers to involvement. academics and older people share some perceptions about PPI in ageing research, but members of the public are more optimistic about active involvement. Further correspondence between these groups may help to identify feasible involvement activities for older people and encourage collaborative research about ageing. © The Author 2014.

Positive Perception of Aging and Performance in a Memory Task: Compensating for Stereotype Threat?

Fernández-Ballesteros, Rocío; Bustillos, Antonio; Huici, Carmen

2015-01-01

BACKGROUND/STUDY CONTEXT: The aim of this research is to explore whether segments of seniors might be immune to aging stereotypes of the older adult group. Stereotype threat research indicates that older adults show low memory recall under conditions of stereotype threat. Stereotype internalization theory (Levy, 2009) predicts that a positive perception of aging has favorable effects on the behavior and health of older people. A total of 112 older adult participants (62% women, aged 55 to 78) attending the University Programme for Older Adults were assigned to one of two conditions: stereotype threat condition and positive information condition. A control group was included from participants in the same program (n = 34; 61% women, aged 55 to 78). Individual differences in self-perception of aging were considered as continuous variable. Participants with better self-perception of aging showed better memory performance than those with poorer self-perception of aging in the stereotype threat condition and control condition. However, no differences were found in the positive information condition between participants with high and low self-perception of aging. These results indicate that positive self-perception of aging moderates the effects of stereotype threat, and that positive information promotes better memory performance for those older adults with a poorer self-perception of aging. As expected, individuals with a positive perception of their own aging were less vulnerable to the activation of a negative older adult stereotype in the stereotype threat condition.

In 2011, the UK physical activity guidelines were updated to include recommendations for muscle strengthening and balance & coordination (at least two sessions of relevant activities per week). However, monitoring and policy efforts remain focussed on aerobic activity. This study aimed to assess differences by gender and age in the a) prevalence of muscle strengthening and balance & co-ordination guidelines, and b) participation in guideline-specific activities. The sample for the muscle strengthening analyses was 10,488 adult (16-64 years) and 3857 older adult (≥65 years) 2012-2014 Scottish Health Survey respondents. The balance & co-ordination analyses used only the older adult responses. Differences by gender and (where possible) age in guideline prevalence and activity participation were assessed using logistic regression and t-tests. Thirty-one percent of men and 24 % of women met the muscle strengthening guideline, approximately half that of published figures for aerobic physical activity. Nineteen percent of older men and 12 % of older women met the balance & co-ordination guidelines. The oldest age groups were less likely to meet both guidelines compared to the youngest age groups. Differences by gender were only evident for muscle strengthening: more men met the guidelines than women in all age groups, with the largest difference amongst 16-24 year olds (55 % men compared with 40 % women). Participation in relevant activities differed by gender for both guidelines. 'Workout at gym' was the most popular activity to improve muscle strength for men (18 % participated), while swimming was for women (15 % participated). Golf was the most popular activity to improve balance & co-ordination for older men (11 % participated) and aerobics was for older women (6 % participated). Participation decreased in most muscle strengthening activities for both men and women. One exception was golf, where participation levels were as high amongst older men as in younger age groups, although overall levels were low (3 % of all men). Physical activity policy should aim to increase prevalence of these 'forgotten' guidelines, particularly amongst young women (for muscle strengthening) and older age groups (both guidelines). Gender and age participation differences should be considered when designing population-level interventions.

The present study examined the impact of cognitive reserve in maintaining intact neuropsychological (NP) function among older HIV-positive individuals, a uniquely at-risk subgroup. Participants included 129 individuals classified by HIV serostatus, age group, and NP impairment. A three-way analysis of variance (ANOVA) followed by a series of within-group ANOVA and multiple regression analyses were conducted to investigate the pattern of cognitive reserve (vs. other protective) influence among groups with varying risks of NP impairment. Results indicated a significant age ×HIV status interaction, with older HIV-positive individuals demonstrating higher cognitive reserve than subgroups with less risk for NP compromise (younger age and/or HIV-negative). Results demonstrated higher cognitive reserve specific to NP-intact older HIV-positive individuals. Within this group, the interaction of younger age and higher cognitive reserve independently contributed to cognitive status when controlling for psychiatric, immunological, and psychosocial protective mechanisms, suggesting the importance of cognitive reserve beyond other protective mechanisms in maintaining optimal NP functioning in those individuals most at risk. Alongside younger age, factors contributing to cognitive reserve (i.e., education and estimated premorbid intelligence) may provide substantial benefit for older HIV-positive adults who are at high risk for NP compromise.

OBJECTIVE: to identify the changes which had occurred over the last year in the life of older adults, as well as the values attributed to these changes. METHOD: this is a multicentric, cross-sectional study, of the inquiry type, undertaken in three cities of the Brazilian Northeast, investigating two distinct groups of older adults. RESULTS: among the 236 older adults interviewed, it was observed that 30.0% reported health as the main change in their life course in the last year, this category being the most significant response among the older adults aged between 80 and 84 years old (37.7%). Changes in the family were mentioned by 11.5% of the older adults; death (9.6%) and alterations in routine activities (9.6%). In relation to the value attributed to these changes, it was ascertained that for 64.7% of the older adults aged between 65 and 69 years old, these changes were positive. In the older group, 49.4% of the older adults believe that their changes were related to losses. CONCLUSION: the knowledge of the changes mentioned, the value attributed to these changes, and the self-evaluation of health provide information which assists in formulating actions which are more specific to the real needs of these age groups. They also provide the health professionals with a better understanding of how some experiences are experienced in the life trajectories of these older adults. PMID:25806625

Background There is scarce or no data on prevalence and presentation of acute coronary syndrome (ACS) among women of reproductive age. Furthermore, whether women of reproductive age presenting with ACS have the same risk factors as men and older women is not known. Objective To analyze factors associated with ACS in women of reproductive age in comparison with older women and men of a similar age group. Methodology A total of 9702 cases of acute coronary syndrome over a 3-year period ( 2006–2008) from the National Cardiovascular Disease database were analyzed, with focus on women of reproductive age (20–<40 years), looking into association with ethnicity, comorbid illness, and the ACS stratum. Comparison with older women (40–<60 years; Control 1) and men of similar age group (Control 2) was made and analyzed using Fisher’s exact test and chi-square test when necessary. Results From a total of 9702 cases, 2344 (24.2%) were women. Of these, 45 (1.9%) were women between 20 and <40 years, which is significantly lower than the two controls (older women 30.8%, and men of same age 6.2%, respectively; P < 0.0001). The distribution of ethnicity shows a similar pattern between the study group and the controls, but patients of Indian ethnicity were over-represented when compared with the Malaysian demographics of general population (31.3% versus 7.1%; P < 0.0001). ACS in women of reproductive age was associated with diabetes mellitus in 37.8%, hypertension in 40.0%, and dyslipidemia in 24.4% of cases, similar to men of the same age but significantly lower than the older women (P < 0.0001). Smoking is not a major risk factor in the study group, where only 6.7% ever smoked, similar to older women (6.8%, P = 1.000) and significantly much less compared with men of the same age (84.1%; P < 0.0001). Regarding the ACS stratum, a significantly higher percentage of women in the study group had ST-segment elevation myocardial infarction compared with older women (P = 0.0085) but less than that of men of similar age (P = 0.0187). Conclusion ACS is rare in women of reproductive age. Diabetes, hypertension, and Indian ethnicity were identified as important contributors. PMID:22140324

Support groups for older victims of domestic violence.

PubMed

Wolf, R S

2001-01-01

A 1997 nationwide (US and Canada) search to identify support groups for older victims of domestic violence located 16 sponsored by domestic violence programs and 14 sponsored by aging services. Interviews with group leaders indicated more similarities than differences between the two types of sponsorship in group purpose, leadership, numbers served, content of support group sessions, and success in accomplishing goals. Resistance of elders to participate in a group experience was cited by leaders as a major barrier. Recommendations for future groups include insuring accessibility of meeting site; using a leader and co-leader, at least one of whom is older or familiar with aging issues; allocating resources for recruitment; and seeking a steady source of funding. A policy of collaboration among the state's domestic violence coalition, state unit on aging, adult protective services, and victim assistance program may help in promoting support group development and utilization.

Research from the USA and Great Britain indicates that the number of fatal crashes (as well as the rates of crashes of all levels of injury and property damage) involving older drivers declined between approximately 1997 and 2010 despite increases in the number of older drivers on the road and in their driving exposure. Differing results have been found in Australian research with the number of older driver fatalities having been steady and even slightly increasing between 2004 and 2013. The present study further examined trends in the crash involvement of older drivers in Australia to determine whether their involvement has been increasing or decreasing, and how this compares to trends for younger aged drivers. Crash, injury, population and licensure data were examined by age group for the years 2003-2012. There were increases in the population and licensure of drivers aged 65 years and older, while the total crashes, serious injuries, and fatalities remained steady for drivers aged 65-84 and increased for the oldest group (85+) between 2003 and 2012. Increasing trends were also found for drivers 85 and older for rates of serious or fatal injuries per head of population and per licensed driver. Population and licensure among younger age groups also increased but their crash numbers and crash rates remained steady or declined. The stable or slightly increasing fatal crash involvement of older drivers in Australia contrasts with the declining trends in the USA and Great Britain. Therefore, greater attention should be given to the road safety of older drivers in Australia. Copyright © 2018 Elsevier Ltd. All rights reserved.

Stress and coping among gay men: age and ethnic differences.

PubMed

David, Steven; Knight, Bob G

2008-03-01

Previous studies suggest that perceived stigmatization of sexual minority status, ethnicity, and age are associated with negative mental health outcomes, and other studies suggest that coping styles may influence these outcomes. However, no studies have examined these relationships among gay men of varying ethnicities and age groups. Three hundred eighty-three Black and White, younger, middle-aged, and older adult gay men completed measures of perceived stigmatization, coping style, and mental health outcomes. Black older adult gay men reported significantly higher levels of perceived ageism than the older White group, significantly higher levels of perceived racism than the younger Black group, significantly higher levels of homonegativity than the younger Black and the White groups, and were more likely to use disengaged coping styles than White gay men. However, Black older adult gay men did not experience significantly higher levels of negative mental health outcomes. Results suggest that further research should examine how older Black gay men, who perceive higher levels of stigma while reporting greater use of less effective coping styles, do not appear to be experiencing more negative mental health outcomes as a result.

Social support and hope are considered positive, important contributors to psychological well-being for women with breast cancer and their spouses. Few studies examine the role of age in relation to these variables. The current study compares the relationship between social support, hope and depression among different age groups of women with advanced breast cancer and their healthy spouses. Cross-sectional sample of 150 women with advanced breast cancer and their spouses. Social support, hope, depression and socio-demographic data. Analysis included comparison of these variables between groups of older and younger patients and their spouses. Structural equation modelling (SEM) was used to examine hope as a mediator of the relationship between social support and depression within each group (older and younger patients and spouses). Older patients and spouses reported lower levels of depression than younger ones. SEM showed that social support related directly to depression among younger women and older spouses, while hope was directly related to depression among older women and younger spouses and acted as a mediator between social support and depression. Theoretical, empirical and clinical implications regarding the understanding of the role of age in coping with cancer are discussed.

Supracondylar humerus fractures are the most common operative fractures in children; however, no studies describe the older child with this injury. The purpose of this study was to compare Gartland type III supracondylar humerus fractures in children older than 8 years of age with those in younger children than age 8. We hypothesized that there would be more complications in older children, reflecting a higher-energy injury mechanism. A retrospective chart review of supracondylar humerus fractures managed at a single level I pediatric trauma institution from 2004 to 2007 was performed. Patients with type III fractures were divided into groups based on age at presentation greater or less than 8. Baseline demographics, fracture characteristics, mechanism of injury, operative technique, and complications were analyzed. A consecutive series of 1297 pediatric patients with surgically treated supracondylar humerus fractures was retrospectively reviewed including 873 (67.3%) type III fractures. Of those, 160 (18.3%) patients were older than age 8 at time of injury. Older children were more likely to have fractures from high-energy mechanisms (45.1% vs. 28.7%, P<0.001) and more open fracture (3.8% vs. 1.3%, P=0.0097). There was no difference in preoperative or iatrogenic neuropraxias between groups. There was a shorter delay between presentation and surgery in older children (mean, 217 vs. 451 min, P<0.0001). Three or more pins were used more often in older patients (61.8% in older children vs. 43.6% in younger children, P<0.0001). Major complications including reoperation, loss of fixation, or compartment syndrome were rare in both groups (1.1% in younger group vs. 0.6% in older group, P=1.000). There was a trend toward more pin site infections in older children (3.75% vs. 1.56%, P=0.071). Physical therapy was required nearly 4 times more frequently in older children for management of residual stiffness (20.0% vs. 5.7%, P<0.0001). Children older than 8 years of age have a higher rate of open supracondylar humerus fractures, although nerve injury rates are similar. Surgeons placed more pins for fixation of fractures in older patients and elbow stiffness requiring physical therapy occurred more commonly after surgical intervention. III Retrospective cohort.

The neural systems most susceptible to age-related decline mirror the systems linked to decision making. Yet, the neural processes underlying decision-making disparities among older adults are not well understood. We sought to identify neural response patterns that distinguish 2 groups of older adults who exhibit divergent decision-making patterns. Participants were 31 healthy older adults (ages 59-88, 53% female), defined as advantageous or disadvantageous decision-makers based on Iowa Gambling Task (IGT) performance, who completed an alternate version of the IGT while undergoing functional MRI. The groups were indistinguishable on neuropsychological testing. We contrasted the BOLD signal between groups during 3 phases of the decision-making process: Prechoice (preselection), Prefeedback (postselection), and Feedback (receipt of gains/losses). We further examined whether BOLD signal varied as a function of age in each group. We observed greater activation among the IGT-Disadvantageous relative to -Advantageous older adults in the prefrontal cortex during the early phases of the decision-making process (Prechoice), and in posterior brain regions (e.g., the precuneus) during the later phases (Prefeedback and Feedback). We also found that with increasing age, IGT-Advantageous older adults showed increasing activation in the prefrontal cortex during all phases and increasing activation in the posterior cingulate during earlier phases of the decision process. By contrast, the IGT-Disadvantageous older adults exhibited a reduced or reversed trend. These functional differences may be a consequence of altered reward processing or differing compensatory strategies between IGT-Disadvantageous and -Advantageous older adults. This supports the notion that divergent neurobiological aging trajectories underlie disparate decision-making patterns. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Older driver crash rates in relation to type and quantity of travel.

PubMed

Keall, Michael D; Frith, William J

2004-03-01

It is a well-established phenomenon that, notwithstanding their overall good crash record, older drivers have a higher than average rate of involvement in injury crashes when the rate is calculated by dividing crash numbers by distance driven. It has been hypothesised that at least some of this higher crash rate is an artefact of the different nature of driving undertaken by many older drivers. For example, driving in congested urban environments provides more opportunities for collisions than driving the same distance on a motorway. However, there have been few opportunities to investigate this theory, as relevant data are difficult to acquire. High-quality data from the New Zealand Travel Survey (1997/1998) were combined with crash data to enable a statistical model to estimate the risk of driver groups under various driving conditions characterised by the type of road used, time of day, day of week, and season of year. Despite elevated crash risks per distance driven compared with middle-aged drivers for most road types, older drivers were as safe as any other age group when driving on motorways. Accounting for the fragility of older drivers and their passengers in the risk estimates for other road types, older drivers appeared to have daytime risks comparable to 25-year-olds and night-time risks as low as any other age group. The driving patterns of older drivers (in terms of when and where they drive) were estimated to minimize their risks in comparison with the driving patterns of other age groups. These results are of interest to both policy makers and transportation planners working against the background of inevitable increases in the number of older drivers as the population ages.

Sensitivity of negative subsequent memory and task-negative effects to age and associative memory performance.

2015-07-01

The present fMRI experiment employed associative recognition to investigate the relationships between age and encoding-related negative subsequent memory effects and task-negative effects. Young, middle-aged and older adults (total n=136) were scanned while they made relational judgments on visually presented word pairs. In a later memory test, the participants made associative recognition judgments on studied, rearranged (items studied on different trials) and new pairs. Several regions, mostly localized to the default mode network, demonstrated negative subsequent memory effects in an across age-group analysis. All but one of these regions also demonstrated task-negative effects, although there was no correlation between the size of the respective effects. Whereas negative subsequent memory effects demonstrated a graded attenuation with age, task-negative effects declined markedly between the young and the middle-aged group, but showed no further reduction in the older group. Negative subsequent memory effects did not correlate with memory performance within any age group. By contrast, in the older group only, task-negative effects predicted later memory performance. The findings demonstrate that negative subsequent memory and task-negative effects depend on dissociable neural mechanisms and likely reflect distinct cognitive processes. The relationship between task-negative effects and memory performance in the older group might reflect the sensitivity of these effects to variations in amount of age-related neuropathology.

Increasing measurement accuracy of age-related BOLD signal change: minimizing vascular contributions by resting-state-fluctuation-of-amplitude scaling.

PubMed

Kannurpatti, Sridhar S; Motes, Michael A; Rypma, Bart; Biswal, Bharat B

2011-07-01

In this report we demonstrate a hemodynamic scaling method with resting-state fluctuation of amplitude (RSFA) in healthy adult younger and older subject groups. We show that RSFA correlated with breath hold (BH) responses throughout the brain in groups of younger and older subjects which RSFA and BH performed comparably in accounting for age-related hemodynamic coupling changes, and yielded more veridical estimates of age-related differences in task-related neural activity. BOLD data from younger and older adults performing motor and cognitive tasks were scaled using RSFA and BH related signal changes. Scaling with RSFA and BH reduced the skew of the BOLD response amplitude distribution in each subject and reduced mean BOLD amplitude and variability in both age groups. Statistically significant differences in intrasubject amplitude variation across regions of activated cortex, and intersubject amplitude variation in regions of activated cortex were observed between younger and older subject groups. Intra- and intersubject variability differences were mitigated after scaling. RSFA, though similar to BH in minimizing skew in the unscaled BOLD amplitude distribution, attenuated the neural activity-related BOLD amplitude significantly less than BH. The amplitude and spatial extent of group activation were lower in the older than in the younger group before and after scaling. After accounting for vascular variability differences through scaling, age-related decreases in activation volume were observed during the motor and cognitive tasks. The results suggest that RSFA-scaled data yield age-related neural activity differences during task performance with negligible effects from non-neural (i.e., vascular) sources.

This study describes the fatal crash experiences of older drivers. Data from two U.S. databases (NASS-CDS and FARS) were used. Several crash, vehicle, and occupant characteristics were compared across age groups, including vehicle type, crash direction (PDOF), severity (ΔV), and injured body region. A sub-set of 97 fatally injured drivers was chosen for a detailed case study. The mean travel speed, ΔV, and airbag deployment rate decreased significantly with age (p<0.001 unless noted). Mortality rate increased significantly with age. Older drivers killed were significantly more likely to die of a chest injury (47.3% vs. 24.0% in youngest group) and less likely to die of a head injury (22.0% vs. 47.1% in youngest group). Older drivers were more likely to die at a date after the crash date (“delayed death”), as were males (p=0.003). A 16-year-old driver had a 10.8%–12.0% probability of delayed death, while a 75-year-old had a 20.7%–22.7% probability. For those having a delayed death, the length of the delay increased significantly with age (2.9 days for age 16 vs. 7.9 for age 75). A subjective assessment of the case files indicated that frailty or a pre-existing health condition played a role in 4.3% of the younger drivers’ deaths, but 50.0% of the older group. PMID:16179160

Is There an Age Limit to Lung Transplantation?

2015-08-01

Lung transplantation in patients older than 65 years is increasingly common, but questions remain regarding risk vs benefit and procedure choice. We identified short-term and long-term outcomes in older single-lung transplant (SLT) and bilateral-lung transplant (BLT) recipients. We performed a retrospective review of United Network for Organ Sharing data for patients who underwent lung transplantation between May 2005 and December 2012. Patients were grouped by age, and we calculated short-term and long-term survival rates and compared survival distributions. Of the 11,776 patients who received lung transplants, 9,317 (79%) were aged 12 to 64 years, 1,902 (16%) were 65 to 69, 486 (4%) were 70 to 74, and 71 (1%) were 75 to 79. Short-term survival was similar across all age groups and procedure types except those aged 75 to 79, who had lower short-term survival for BLT. Those aged 12 to 64 had higher 5-year survival for SLT and BLT than all other groups (p < 0.001), and BLT offered a long-term survival advantage over SLT in this group (p < 0.0001). Older age groups trended toward better long-term survival for BLT compared with SLT (65 to 69, p = 0.059; 70 to 74, p = 0.079). Although data were lacking for 5-year survival for those aged 75 to 79, the 3-year survival for BLT in this group was inferior. Lung transplant can be offered to select older patients up to age 74 with acceptable outcomes. SLT may be preferred for elderly patients, but BLT offers acceptable long-term outcomes without significant short-term risk. Patients older than 75 have acceptable short-term outcomes for SLT, but long-term outcomes for SLT and BLT in this group are poor. Copyright © 2015 The Society of Thoracic Surgeons.

Age differences in how consumers behave following exposure to DTC advertising.

PubMed

DeLorme, Denise E; Huh, Jisu; Reid, Leonard N

2006-01-01

This study was conducted to provide additional evidence on how consumers behave following direct-to-consumer (DTC) advertising exposure and to determine if there are differences in ad-prompted acts (drug inquiry and drug requests) between different age groups (i.e., older, mature, and younger adults). The results suggest that younger, mature, and older consumers are all moved to act by DTC drug ads, but that each age group behaves in different ways. Somewhat surprisingly, age was not predictive of ad-prompted behavior. DTC advertising was no more effective at moving older consumers to behave than their younger counterparts. These results suggest that age does not matter that much when it comes to the "moving power" of prescription drug advertising, even though research indicates that older consumers are more vulnerable to the persuasive effects of communication.

Elderly road collision injury outcomes associated with seat positions and seatbelt use in a rapidly aging society—A case study in South Korea

PubMed Central

Noh, Yuna

2017-01-01

Introduction Aging has long been regarded as one of the most critical factors affecting crash injury outcomes. In South Korea, where the elderly population is projected to reach 35.9% by 2050, the implications of an increasing number of elderly vehicle users on road safety are evident. In this research, the confounding effect of occupant age in a vehicle in terms of seat position and seatbelt use was investigated. In addition, elderly occupants were divided into a younger-old group aged between 65 and 74 years and an older-old group aged 75 years and older in an effort to assess whether the conventional elderly age standard of 65 years should be reconsidered. Methods A multinomial logit framework was adopted to predict two-level injury severity using collision data between 2008 and 2015. Predictor variables included gender, age group, seat position, seatbelt, road type, road slope, road surface, road line, and type of vehicle. Five models, a base model with no interactions and four interaction models which were combinations of age group, seatbelt use and seat position, were devised and evaluated. Results With no interacting term, age was the most prominent predictor. Elderly occupants were most likely to suffer from severe injury without a seatbelt in all seat positions, and the use of a seatbelt reduced this likelihood the most in the elderly group as well. Front passenger seats had the highest risk to elderly occupants, while the driver seat was statistically insignificant. When the elderly group was divided into the younger-old group and the older-old group, the older-olds were found to be much more vulnerable compared to the younger-olds. In particular, older drivers were five times more likely to suffer a severe injury without a seatbelt. Conclusions The degree of injury severity of elderly occupants was reduced the most with the use of a seatbelt, demonstrating the importance of using seat restraints. The sharp increase in the risk of injury of the older-old group suggests that the age standard of 65 years as the elderly group with regard to traffic safety may require reconsideration due to the growing number of elderly vehicle users on the road. Our results provide practical evidence with which to formulate new safety policies, including mandatory seatbelt use, driving age limits and insurance pricing. PMID:28800595

Introduction Medical cannabis is increasingly being used for a variety of health conditions as more states implement legislation permitting medical use of cannabis. Little is known about medical cannabis use patterns and motives among adults across the lifespan. Methods The present study examined data collected at a medical cannabis dispensary in San Francisco, California. Participants included 217 medical cannabis patients who were grouped into age-defined cohorts (younger: 18–30, middle-aged: 31–50, and older: 51–72). The age groups were compared on several measures of cannabis use, motives and medical conditions using one-way ANOVAs, chi-square tests and linear regression analyses. Results All three age groups had similar frequency of cannabis use over the past month; however, the quantity of cannabis used and rates of problematic cannabis use were higher among younger users relative to middle-aged and older adults. The association between age and problematic cannabis use was moderated by age of regular use initiation such that earlier age of regular cannabis use onset was associated with more problematic use in the younger users, but not among older users. Middle-aged adults were more likely to report using medical cannabis for insomnia, while older adults were more likely to use medical cannabis for chronic medical problems such as cancer, glaucoma and HIV/AIDS. Younger participants reported cannabis use when bored at a greater rate than middle-aged and older adults. Conclusions Findings suggest that there is an age-related risk for problematic cannabis use among medical cannabis users, such that younger users should be monitored for cannabis use patterns that may lead to deleterious consequences.

Triceps surae muscle-tendon properties in older endurance- and sprint-trained athletes.

Previous studies have shown that aging is associated with alterations in muscle architecture and tendon properties (Morse CI, Thom JM, Birch KM, Narici MV. Acta Physiol Scand 183: 291-298, 2005; Narici MV, Maganaris CN, Reeves ND, Capodaglio P. J Appl Physiol 95: 2229-2234, 2003; Stenroth L, Peltonen J, Cronin NJ, Sipila S, Finni T. J Appl Physiol 113: 1537-1544, 2012). However, the possible influence of different types of regular exercise loading on muscle architecture and tendon properties in older adults is poorly understood. To address this, triceps surae muscle-tendon properties were examined in older male endurance (OE, n = 10, age = 74.0 ± 2.8 yr) and sprint runners (OS, n = 10, age = 74.4 ± 2.8 yr), with an average of 42 yr of regular training experience, and compared with age-matched [older control (OC), n = 33, age = 74.8 ± 3.6 yr] and young untrained controls (YC, n = 18, age = 23.7 ± 2.0 yr). Compared with YC, Achilles tendon cross-sectional area (CSA) was 22% (P = 0.022), 45% (P = 0.001), and 71% (P < 0.001) larger in OC, OE, and OS, respectively. Among older groups, OS had significantly larger tendon CSA compared with OC (P = 0.033). No significant between-group differences were observed in Achilles tendon stiffness. In older groups, Young's modulus was 31-44%, and maximal tendon stress 44-55% lower, than in YC (P ≤ 0.001). OE showed shorter soleus fascicle length than both OC (P < 0.05) and YC (P < 0.05). These data suggest that long-term running does not counteract the previously reported age-related increase in tendon CSA, but, instead, may have an additive effect. The greatest Achilles tendon CSA was observed in OS followed by OE and OC, suggesting that adaptation to running exercise is loading intensity dependent. Achilles tendon stiffness was maintained in older groups, even though all older groups displayed larger tendon CSA and lower tendon Young's modulus. Shorter soleus muscle fascicles in OE runners may be an adaptation to life-long endurance running. Copyright © 2016 the American Physiological Society.

This study examined the effects of age and gender on wideband energy absorbance in adults with normal middle ear function. Forty young adults (14 men, 26 women, aged 20-38 years), 31 middle-aged adults (16 men, 15 women, aged 42-64 years), and 30 older adults (20 men, 10 women, aged 65-82 years) were assessed. Energy absorbance (EA) data were collected at 30 frequencies using a prototype commercial instrument developed by Interacoustics. Results showed that the young adult group had significantly lower EA (between 400 and 560 Hz) than the middle-aged group. However, the middle-aged group showed significantly lower EA (between 2240 and 5040 Hz) than the young adult group. In addition, the older adult group had significantly lower EA than the young adult group (between 2520 and 5040 Hz). No significant difference in EA was found at any frequency between middle-aged and older adults. Across age groups, gender differences were found with men having significantly higher EA values than women at lower frequencies, whereas women had significantly higher EA at higher frequencies. This study provides evidence of the influence of gender and age on EA in adults with normal outer and middle ear function. These findings support the importance of establishing age- and gender-specific EA norms for the adult population.

Genetic and environmental influences on word recognition and spelling deficits as a function of age.

Previous twin studies have suggested a possible developmental dissociation between genetic influences on word recognition and spelling deficits, wherein genetic influence declined across age for word recognition, and increased for spelling recognition. The present study included two measures of word recognition (timed, untimed) and two measures of spelling (recognition, production) in younger and older twins. The heritability estimates for the two word recognition measures were .65 (timed) and .64 (untimed) in the younger group and .65 and .58 respectively in the older group. For spelling, the corresponding estimates were .57 (recognition) and .51 (production) in the younger group and .65 and .67 in the older group. Although these age group differences were not significant, the pattern of decline in heritability across age for reading and increase for spelling conformed to that predicted by the developmental dissociation hypothesis. However, the tests for an interaction between genetic influences on word recognition and spelling deficits as a function of age were not significant.

Background Internet technology can provide a diverse array of online resources for low-income disabled and homebound older adults to manage their health and mental health problems and maintain social connections. Despite many previous studies of older adults’ Internet use, none focused on these most vulnerable older adults. Objective This study examined Internet use patterns, reasons for discontinued use, eHealth literacy, and attitudes toward computer/Internet use among low-income homebound individuals aged 60 and older in comparison to their younger counterparts—homebound adults under age 60. Methods Face-to-face or telephone surveys were conducted with 980 recipients of home-delivered meals in central Texas (78% were age 60 years and older and 22% under age 60). The eHealth Literacy Scale (eHEALS) and the efficacy and interest subscales of the Attitudes Toward Computer/Internet Questionnaire (ATC/IQ) were used to measure the respective constructs. Age groups were compared with chi-square tests and t tests. Correlates of Internet use were analyzed with multinomial logistic regression, and correlates of eHEALS and ATC/IQ scores were analyzed with OLS regression models. Results Only 34% of the under-60 group and 17% of the 60 years and older group currently used the Internet, and 35% and 16% of the respective group members reported discontinuing Internet use due to cost and disability. In addition to being older, never users were more likely to be black (OR 4.41; 95% CI 2.82-6.91, P<.001) or Hispanic (OR 4.69; 95% CI 2.61-8.44, P<.001), and to have lower incomes (OR 0.36; 95% CI 0.27-0.49, P<.001). Discontinued users were also more likely to be black or Hispanic and to have lower incomes. Among both age groups, approximately three-fourths of the current users used the Internet every day or every few days, and their eHEALS scores were negatively associated with age and positively associated with frequency of use. Among the 60 and older group, a depression diagnosis was also negatively associated with eHEALS scores. ATC/IQ efficacy among never users of all ages and among older adults was positively associated with living alone, income, and the number of medical conditions and inversely associated with age, Hispanic ethnicity, and Spanish as the primary language. Although ATC/IQ interest among older adults was also inversely associated with age, it was not associated with Hispanic ethnicity and Spanish as the primary language. Conclusions This study is the first to describe in detail low-income disabled and homebound adults’ and older adults’ Internet use. It shows very low rates of Internet use compared to the US population, either due to lack of exposure to computer/Internet technology; lack of financial resources to obtain computers and technology; or medical conditions, disabilities, and associated pain that restrict use. Recommendations to reduce the digital divide among these individuals are provided. PMID:23639979

The global population is ageing. As ageing is often associated with a decline in health, there is a need to further develop preventative health measures. Physical activity can positively influence older adults' (aged 50 years and older) health. Previous research on the relationship between physical activity and health for older adults has mainly focused on physical activity in general, and not specific types of exercise. Due to the social nature of sport, it may assist in improving physical, mental and social health for older adults. Sport, as a form of physical activity, has not been widely explored as a physical activity opportunity for older adults. This review concurrently explored two research questions: the determinants and the trends of sport participation for community dwelling older adults. Two parallel systematic searches of nine electronic databases were conducted in December 2015 for the two research questions. English language quantitative and qualitative studies that provided specific results for community dwelling older adults' sport participation were included and a quality ratings assessment was undertaken. There were 10,171 studies initially identified for the first research question and 1992 studies for the second research question. This culminated in 18 and 8 studies respectively that met the inclusion criteria. The most frequently mentioned determinants of participation were health and using sport to negotiate the ageing process. The most frequently mentioned trends of sport participation were the effect of historical sport participation on current participation, and sport participation across the lifespan. The main themes for both research questions had contrasting results, for example, participation in sport could improve health, but poor health was also a limitation of sport participation. This review demonstrates that older adults are a heterogeneous age group, and therefore require different strategies than other age groups to successfully participate in sport. It is recommended that the main findings from this review are incorporated into specific strategies to develop age appropriate sporting opportunities for older adults, so that sport can be presented as a viable physical activity option for this age group.

The aim of this study was to generate reference values and t-scores (1.0-2.5 standard deviations below average) for grip strength for healthy young adults and to examine the utility of t-scores from this group for the identification of dynapenia in older adults. Our investigation was a population-based, general community secondary analysis of cross-sectional grip strength data utilizing the NIH Toolbox Assessment norming sample. Participants consisted of community-dwelling adults, with age ranges of 20-40 years (n = 558) and 60-85 years (n = 390). The main outcome measure was grip strength using a Jamar plus dynamometer. Maximum grip strengths were consistent over the 20-40-year age group [men 108.0 (SD 22.6) pounds, women 65.8 (SD 14.6) pounds]. Comparison of older group grip strengths to those of the younger reference group revealed (depending on age strata) that 46.2-87.1% of older men and 50.0-82.4% of older women could be designated as dynapenic on the basis of t-scores. The use of reference value t-scores from younger adults is a promising method for determining dynapenia in older adults. © 2014 Wiley Periodicals, Inc.

To determine whether patient age, the presence of comorbid illness, and the number of prescribed medications influence the duration of a physician visit in an ambulatory care setting. A cross-sectional study of ambulatory care visits made by adults aged 45 and older to primary care physicians. A probability sample of outpatient follow-up visits in the United States using the National Ambulatory Medical Care Survey (NAMCS) 2002 database. Of 28,738 physician visits in the 2002 NAMCS data set, there were 3,819 visits by adults aged 45 and older included in this study for analysis. The primary endpoint was the time that a physician spent with a patient at each visit. Covariates included for analyses were patient characteristics, physician characteristics, visit characteristics, and source of payment. Visit characteristics, including the number of diagnoses and the number of prescribed medications, the major diagnoses, and the therapeutic class of prescribed medications, were compared for different age groups (45-64, 65-74, and > or =75) to determine the complexity of the patient's medical conditions. Endpoint estimates were computed by age group and were also estimated based on study covariates using univariate and multivariate linear regression. The mean time+/-standard deviation spent with a physician was 17.9+/-8.5 minutes. There were no differences in the duration of visits between the age groups before or after adjustment for patient covariates. Patients aged 75 and older had more comorbid illness and were prescribed more medications than patients aged 45 to 64 and 65 to 74 (P<.001). Patients aged 75 and older were also prescribed more medications that require specific monitoring and counseling (warfarin, digoxin, angiotensin-converting enzyme inhibitors, diuretics, and levothyroxine) than were patients in other age groups (P<.001). Hypertension, coronary artery disease, atrial fibrillation, congestive heart failure, cerebrovascular disease, and transient ischemic attack were more common in patients aged 75 and older than in other age groups (P<.001). Despite these differences, there were no differences in unadjusted or adjusted duration of physician visit between the age groups. Although patients aged 75 and older had more medical conditions and were at higher risk for drug-related problems than younger patients, the duration of physician visits was similar across the age groups. These findings suggest that elderly patients may require a multidisciplinary approach to optimize patient care in the ambulatory setting.

The extent to which cultural stereotypes about aging contribute to age differences in memory performance is investigated by comparing younger and older Anglophone Canadians to demographically matched Chinese Canadians, who tend to hold more positive views of aging. Four memory tests were administered. In contrast to B. Levy and E. Langer's (1994) findings, younger adults in both cultural groups outperformed their older comparison group on all memory tests. For 2 tests, which made use of visual stimuli resembling ideographic characters in written Chinese, the older Chinese Canadians approached, but did not reach, the performance achieved by their younger counterparts, as well as outperformed the older Anglophone Canadians. However, on the other two tests, which assess memory for complex figures and abstract designs, no differences were observed between the older Chinese and Anglophone Canadians. Path analysis results suggest that this pattern of findings is not easily attributed to a wholly culturally based account of age differences in memory performance.

Psychophysical estimation of speed discrimination. II. Aging effects

2005-10-01

We studied the effects of aging on a speed discrimination task using a pair of first-order drifting luminance gratings. Two reference speeds of 2 and 8 deg/s were presented at stimulus durations of 500 ms and 1000 ms. The choice of stimulus parameters, etc., was determined in preliminary experiments and described in Part I. Thresholds were estimated using a two-alternative-forced-choice staircase methodology. Data were collected from 16 younger subjects (mean age 24 years) and 17 older subjects (mean age 71 years). Results showed that thresholds for speed discrimination were higher for the older age group. This was especially true at stimulus duration of 500 ms for both slower and faster speeds. This could be attributed to differences in temporal integration of speed with age. Visual acuity and contrast sensitivity were not statistically observed to mediate age differences in the speed discrimination thresholds. Gender differences were observed in the older age group, with older women having higher thresholds.

To clarify the association between preconception fertility status and obstetric outcomes in women aged 40 years and older. Retrospective study by reviewing medical records. Tertiary perinatal center in a university hospital. 330 women aged 40 years and older who delivered a singleton from 2006 to 2010, and 450 women aged 30 to 34 years who delivered at the same facility as controls. None. Incidence of pregnancy-induced hypertension, gestational diabetes mellitus, preterm birth, low birth weight, and mode of delivery assessed based on the mode of conception; spontaneous conception (SC) and in vitro fertilization/intracytoplasmic sperm injection conception (IVF-ICSI). The incidence of pregnancy-induced hypertension was statistically significantly higher in IVF-ICSI group than the SC group. This gap was commonly observed in both the women aged 40 years and older and those in the 30 to 34 age group. No statistically significant difference was observed in the frequency of gestational diabetes mellitus, preterm birth, or low birth weight. As a characteristic of nulliparous women of advanced age, the rate of operative delivery, which includes emergency cesarean section and instrumental delivery, was statistically significantly higher in IVF-ICSI group than in the SC group. Detailed investigation into the medical indications for operative delivery revealed that the difference was attributable to the elevated incidence of labor protraction and arrest. Preconception fertility status can be a predicting factor of the incidence of pregnancy-induced hypertension and labor outcome, especially for women aged 40 years and older.

Quantify the homeostatic and circadian effects on sleepiness and performance of adolescents. Examine age-related changes in homeostatic and circadian regulation of sleepiness and performance by comparing younger and older adolescent groups. Three-week laboratory study including 12 cycles of a 28-h forced desynchrony protocol. Controlled laboratory environment with individual sleep and performance testing rooms and shared common areas. Twenty-seven healthy adolescents including 16 females. Ages ranged from 9.6-15.2 years and participants were split into younger (n = 14 ages 9-12) and older (n = 13 ages 13-15) groups based on median age split of 13.0 years. N/A. Testing occurred every 2 h during scheduled wake periods. Measures included sleep latency during repeated nap opportunities and scores from a computerized neurobehavioral assessment battery including a 10-min psychomotor vigilance task, a digit symbol substitution task, and the Karolinska Sleepiness Scale. Significant main effects of circadian and homeostatic factors were observed, as well as several circadian and homeostatic interaction effects. Age group did not have a significant main effect on sleep and performance data. A significant interaction of circadian phase and age group was found for sleep latency, with younger adolescents showing greater circadian modulation than older teens during the circadian night. Adolescents demonstrated a similar pattern of response to forced desynchrony as reported for adults. Sleepiness and performance were affected by homeostatic and circadian factors, and age group did not interact with homoeostatic and circadian factors for subjective sleepiness and most performance metrics. Younger adolescents had a shorter latency to sleep onset than older during the circadian bin spanning 4 to 8 h after the onset of melatonin secretion. © 2015 Associated Professional Sleep Societies, LLC.

Requirements for the Crash Protection of Older Vehicle Passengers

Morris, Andrew; Welsh, Ruth; Hassan, Ahamedali

2003-01-01

This study compares injury outcomes in vehicle crashes involving different age groups of belted passengers. Two datasets were considered. Firstly, UK national data revealed that younger passengers are much more likely to be involved in crashes per million miles travelled compared to older passengers although older passengers are much more likely to be killed or seriously injured compared to younger passengers. Secondly, in-depth vehicle crash injury data were examined to determine some of the underlying reasons for the enhanced injury risk amongst older passengers. In crashes of approximately equal severity, the older passenger group were significantly more likely to be fatally injured in frontal crashes (p<0.001). However young passengers were as equally likely to be killed in struck-side crashes compared to the older group. The results also showed that older passengers sustained more serious injuries to the chest region in frontal crashes compared with the younger aged group (p<0.0001) and it is this body region that is particularly problematic. When the data were analysed further, it was found that a large proportion of passengers were female and that in the majority of cases, the seat belt was responsible for injury. Since by the year 2030, 1 in 4 persons will be aged over 65 in most OECD countries, the results suggest a need for intervention through vehicle design including in-vehicle crashworthiness systems that take into account reduced tolerance to impact with ageing.

Many studies have demonstrated that aging is associated with declines in skill acquisition. In the current study, we tested whether older adults could acquire general, transferable knowledge about skill learning processes. Older adult participants learned five different motor tasks. Two older adult control groups performed the same number of trials, but learned only one task. The experimental group exhibited faster learning than that seen in the control groups. These data demonstrate that older adults can learn to learn new motor skills. PMID:17602760

The suicide rate has been increasing in Korea, and the country now has the highest rank in the world. This study aimed to present the long-term trends in Korea's suicide rate using Joinpoint analysis and age-period-cohort (APC) modeling. The population and the number of suicides for each five-year age group were obtained from the National Statistical Office for the period 1984-2013 for Koreans aged 10 years and older. We determined the changes in the trends in age-standardized mortality rates using Joinpoint. APC modeling was performed to describe the trends in the suicide rate using the intrinsic estimator method. The age-standardized suicide rate in men rapidly increased from 1989 to 2004, and slightly increased thereafter, whereas the suicide rate in women increased from 1989 to 2009 and then decreased thereafter. Within the same period, the suicide rate was higher among the older age groups than in the younger groups. Within the same birth cohort, the suicide rate of the older groups was also higher than that in the younger groups. Within the same age group, the suicide rate of the younger cohorts was higher than it was in the older cohorts. In the APC modeling, old age, recent period, and having been born before 1924 were associated with higher suicide rates. The accuracy and completeness of the suicide rate data may lead to bias. This study showed an increasing trend in the suicide rates for men and women after 1989. These trends may be mainly attributed to cohort effects. Copyright © 2016 Elsevier B.V. All rights reserved.

2017-01-01

Background and aims: Maximum phonation time (MPT), which is related to respiratory function, is widely used to evaluate maximum vocal capabilities, because its use is non-invasive, quick, and inexpensive. We aimed to examine differences in MPT by age, following recovery phase II cardiac rehabilitation (CR). Methods: This longitudinal observational study assessed 50 consecutive cardiac patients who were divided into the middle-aged group (<65 years, n = 29) and older-aged group (≥65 years, n = 21). MPTs were measured at 1 and 3 months after cardiac surgery, and were compared. Results: The duration of MPT increased more significantly from month 1 to month 3 in the middle-aged group (19.2 ± 7.8 to 27.1 ± 11.6 s, p < 0.001) than in the older-aged group (12.6 ± 3.5 to 17.9 ± 6.0 s, p < 0.001). However, no statistically significant difference occurred in the % change of MPT from 1 month to 3 months after cardiac surgery between the middle-aged group and older-aged group, respectively (41.1% vs. 42.1%). In addition, there were no significant interactions of MPT in the two groups for 1 versus 3 months (F = 1.65, p = 0.20). Conclusion: Following phase II, CR improved MPT for all cardiac surgery patients. PMID:29267218

Older age is considered a poor prognostic factor in acute liver failure (ALF) and may still be considered a relative contraindication for liver transplantation for ALF. We aimed to evaluate the impact of older age, defined as age > or = 60 years, on outcomes in patients with ALF. One thousand one hundred twenty-six consecutive prospective patients from the US Acute Liver Failure Study Group registry were studied. The median age was 38 years (range, 15-81 years). One thousand sixteen patients (90.2%) were younger than 60 years (group 1), and 499 (49.1%) of these had acetaminophen-induced ALF; this rate of acetaminophen-induced ALF was significantly higher than that in patients > or = 60 years (group 2; n = 110; 23.6% with acetaminophen-induced ALF, P < 0.001). The overall survival rate was 72.7% in group 1 and 60.0% in group 2 (not significant) for acetaminophen patients and 67.9% in group 1 and 48.2% in group 2 for non-acetaminophen patients (P < 0.001). The spontaneous survival rate (ie, survival without liver transplantation) was 64.9% in group 1 and 60.0% in group 2 (not significant) for acetaminophen patients and 30.8% in group 1 and 24.7% in group 2 for non-acetaminophen patients (P = 0.27). Age was not a significant predictor of spontaneous survival in multiple logistic regression analyses. Group 2 patients were listed for liver transplantation significantly less than group 1 patients. Age was listed as a contraindication for transplantation in 5 patients. In conclusion, in contrast to previous studies, we have demonstrated a relatively good spontaneous survival rate for older patients with ALF when it is corrected for etiology. However, overall survival was better for younger non-acetaminophen patients. Fewer older patients were listed for transplantation.

Prevalence and Clinical Correlates of Sarcopenia in Community-Dwelling Older People: Application of the EWGSOP Definition and Diagnostic Algorithm

PubMed Central

2014-01-01

Background. Muscle impairment is a common condition in older people and a powerful risk factor for disability and mortality. The aim of this study was to apply the European Working Group on Sarcopenia in Older People criteria to estimate the prevalence and investigate the clinical correlates of sarcopenia, in a sample of Italian community-dwelling older people. Methods. Cross-sectional analysis of 730 participants (74% aged 65 years and older) enrolled in the InCHIANTI study. Sarcopenia was defined according to the European Working Group on Sarcopenia in Older People criteria using bioimpedance analysis for muscle mass assessment. Logistic regression analysis was used to identify the factors independently associated with sarcopenia. Results. Sarcopenia defined by the European Working Group on Sarcopenia in Older People criteria increased steeply with age (p < .001), with 31.6% of women and 17.4% of men aged 80 years or older being affected by this condition. Higher education (odds ratio: 0.85; 95% CI: 0.74–0.98), lower insulin-like growth factor I (lowest vs highest tertile, odds ratio: 3.89; 95% CI: 1.03–14.1), and low bioavailable testosterone (odds ratio: 2.67; 95% CI: 1.31–5.44) were independently associated with the likelihood of being sarcopenic. Nutritional intake, physical activity, and level of comorbidity were not associated with sarcopenia. Conclusions. Sarcopenia identified by the European Working Group on Sarcopenia in Older People criteria is a relatively common condition in Italian octogenarians, and its prevalence increases with aging. Correlates of sarcopenia identified in this study might suggest new approaches for prevention and treatment of sarcopenia. PMID:24085400

THE EFFECT OF PLAUSIBILITY ON SENTENCE COMPREHENSION AMONG OLDER ADULTS AND ITS RELATION TO COGNITIVE FUNCTIONS

2016-01-01

Background/Study Context Older adults show age-related decline in complex-sentence comprehension. This has been attributed to a decrease in cognitive abilities that may support language processing, such as working memory (e.g., Caplan, DeDe, Waters, & Michaud, 2011,Psychology and Aging, 26, 439–450). The authors examined whether older adults have difficulty comprehending semantically implausible sentences and whether specific executive functions contribute to their comprehension performance. Methods Forty-two younger adults (aged 18–35) and 42 older adults (aged 55–75) were tested on two experimental tasks: a multiple negative comprehension task and an information processing battery. Results Both groups, older and younger adults, showed poorer performance for implausible sentences than for plausible sentences; however, no interaction was found between plausibility and age group. A regression analysis revealed that inhibition efficiency, as measured by a task that required resistance to proactive interference, predicted comprehension of implausible sentences in older adults only. Consistent with the compensation hypothesis, the older adults with better inhibition skills showed better comprehension than those with poor inhibition skills. Conclusion The findings suggest that semantic implausibility, along with syntactic complexity, increases linguistic and cognitive processing loads on auditory sentence comprehension. Moreover, the contribution of inhibitory control to the processing of semantic plausibility, particularly among older adults, suggests that the relationship between cognitive ability and language comprehension is strongly influenced by age.

This has been attributed to a decrease in cognitive abilities that may support language processing, such as working memory (e.g., Caplan, DeDe, Waters, & Michaud, 2011,Psychology and Aging, 26, 439-450). The authors examined whether older adults have difficulty comprehending semantically implausible sentences and whether specific executive functions contribute to their comprehension performance. Forty-two younger adults (aged 18-35) and 42 older adults (aged 55-75) were tested on two experimental tasks: a multiple negative comprehension task and an information processing battery. Both groups, older and younger adults, showed poorer performance for implausible sentences than for plausible sentences; however, no interaction was found between plausibility and age group. A regression analysis revealed that inhibition efficiency, as measured by a task that required resistance to proactive interference, predicted comprehension of implausible sentences in older adults only. Consistent with the compensation hypothesis, the older adults with better inhibition skills showed better comprehension than those with poor inhibition skills. The findings suggest that semantic implausibility, along with syntactic complexity, increases linguistic and cognitive processing loads on auditory sentence comprehension. Moreover, the contribution of inhibitory control to the processing of semantic plausibility, particularly among older adults, suggests that the relationship between cognitive ability and language comprehension is strongly influenced by age.

Abstract Age differences in human brain plasticity are assumed, but have not been systematically investigated. In this longitudinal study, we investigated changes in white matter (WM) microstructure in response to memory training relative to passive and active control conditions in 183 young and older adults. We hypothesized that (i) only the training group would show improved memory performance and microstructural alterations, (ii) the young adults would show larger memory improvement and a higher degree of microstructural alterations as compared to the older adults, and (iii) changes in memory performance would relate to microstructural alterations. The results showed that memory improvement was specific to the training group, and that both the young and older participants improved their performance. The young group improved their memory to a larger extent compared to the older group. In the older sample, the training group showed less age‐related decline in WM microstructure compared to the control groups, in areas overlapping the corpus callosum, the cortico‐spinal tract, the cingulum bundle, the superior longitudinal fasciculus, and the anterior thalamic radiation. Less microstructural decline was related to a higher degree of memory improvement. Despite individual adaptation securing sufficient task difficulty, no training‐related group differences in microstructure were found in the young adults. The observed divergence of behavioral and microstructural responses to memory training with age is discussed within a supply‐demand framework. The results demonstrate that plasticity is preserved into older age, and that microstructural alterations may be part of a neurobiological substrate for behavioral improvements in older adults.

To identify attitudes and bias toward aging between Asian and White students and identify factors affecting attitudes toward aging. A cross-sectional sample of 308 students in a nursing program completed the measure of Attitudes Toward Older People and Aging Quiz electronically. There were no differences in positive attitudes and pro-aged bias between Asian and White groups, but Asian students had significantly more negative attitudes and anti-aged bias toward older people than White students. Multiple regression analysis showed ethnicity/race was the strongest variable to explain negative attitudes toward older people. Feeling uneasy about talking to older adults was the most significant factor to explain all attitudinal concepts. Asian students were uneasy about talking with older people and had negative attitudes toward older adults. To become competent in cross-cultural care and communication in nursing, educational strategies to reduce negative attitudes on aging are necessary. © The Author(s) 2014.

AIM: The study aimed to analyse differences in colourimetric parameters L*a*b*, depended on age. MATERIAL AND METHODS: In this study were included 255 subjects with age interval from 20 to 49 years. The subjects were divided into three groups, as follows: in the younger group were 20 to 29 years of age, those in the middle group 30 to 39 years and older group 40 to 49 years. The overall number of analysed teeth in the intercanine sector of the maxilla was 2295. The colour of the teeth was measured using the spectrophotometer VITA Easyshade. RESULTS: The results for differences in the colourimetric parameters in relation with age were tested with Pearson Chi-square (χ2). For χ2 = 572, 87 and df = 124 there was a statistical significant difference between the ages P < 0.001. CONCLUSION: In this study, it was concluded that the parameter L* - Lightness was decreasing when age increased. In the age group, 20 to 29 years L* was 83.2, whereas in the older group of this investigation; 40 to 49 years was 79.4. In the youngest group, the parameter a* was - 0.7, whereas with increasing of age this parameter was -0.5. The values for parameter b* from the youngest to the older group were from 21.7 to 23.9.

traumatic brain injury (TBI) is a significant public health problem. Developed countries report a significant increase of TBI in older adults in the past decades. The objective of this study was to investigate the changes in TBI-related mortality in older Austrians (65 years or older) between 1980 and 2012 (33 years) and to identify possible causes for these changes. data from Statistics Austria on mortality in Austria between 1980 and 2012 were screened and data on TBI-related mortality in adults aged 65 and older were extracted and analysed, based on the diagnostic codes of the International Classification of Diseases, 10th and 9th revision. Mortality rates were calculated for 5-year age groups; standardized mortality rates were calculated for the total. Mechanism of injury was analysed for all events, both sexes and individual age groups. between 1980 and 2012, 16,204 people aged 65 or older died from TBI in Austria; 61% of these were male. Fatal TBI cases and mortality rates increased in the oldest age groups (80 years or older). Half of the fatal TBI cases were caused by falls, 22% by traffic accidents and 17% by suicides. Rate of fall-related fatal TBI increased and rate of traffic accident-related fatal TBI decreased with age. preventive measures introduced in the past decades in the developed countries have contributed to a decrease in traffic injuries. However, falls in the older population are on the rise, mainly due to ageing of the population, throughout the reported period. It is important to take preventive measures to stop the epidemics of fall-related TBIs and fatalities in older adults. © The Author 2014.

Normal aging is associated with both structural changes in many brain regions and functional declines in several cognitive domains with advancing age. Advanced neuroimaging techniques enable explorative analyses of structural alterations that can be used as assessments of such age-related changes. Here we used voxel-based morphometry (VBM) to investigate regional and global brain volume differences among four groups of healthy adults from the IXI Dataset: older females (OF, mean age 68.35 yrs; n=69), older males (OM, 68.43 yrs; n=66), young females (YF, 27.09 yrs; n=71), and young males (YM, 27.91 yrs; n=71), using 3D T1-weighted MRI data. At the global level, we investigated the influence of age and gender on brain volumes using a two-way analysis of variance. With respect to gender, we used the Pearson correlation to investigate global brain volume alterations due to age in the older and young groups. At the regional level, we used a flexible factorial statistical test to compare the means of gray matter (GM) and white matter (WM) volume alterations among the four groups. We observed different patterns in both the global and regional GM and WM alterations in the young and older groups with respect to gender. At the global level, we observed significant influences of age and gender on global brain volumes. At the regional level, the older subjects showed a widespread reduction in GM volume in regions of the frontal, insular, and cingulate cortices compared to the young subjects in both genders. Compared to the young subjects, the older subjects showed a widespread WM decline prominently in the thalamic radiations, in addition to increased WM in pericentral and occipital areas. Knowledge of these observed brain volume differences and changes may contribute to the elucidation of mechanisms underlying aging as well as age-related brain atrophy and disease. PMID:29344423

The objective of this study was to provide a better understanding of the verbal learning and memory (VLM) patterns that might differentiate children with frontal lobe epilepsy (FLE) from children with temporal lobe epilepsy (TLE) and to examine the impact of variables thought to influence outcomes (seizure laterality, age at seizure onset, age at assessment, epilepsy duration, number of antiepileptic drugs). Retrospective analyses were carried out for children with intractable unilateral TLE (n=100) and FLE (n=27) who completed standardized measures of VLM entailing lists of single words or lists of word pairs. Mean intelligent quotients and VLM scores on single words fell within the average range for both groups, whereas scores fell within the low average to borderline range on word pairs. No significant overall differences in VLM were found between the group with TLE and the group with FLE. Older age at assessment and older age at seizure onset were generally associated with better VLM in both groups but were related to better performance in a number of indices in the group with TLE and only fewer intrusions in the group with FLE. The VLM profiles of children with TLE and FLE are generally similar. Older age at assessment and older age at seizure onset have a favorable impact on both groups but are related to better encoding, retrieval, and monitoring processes for the group with TLE and improved memory monitoring (i.e., as indicated by fewer intrusions) in the group with FLE.

Given the increasing number of older people, China has become an aging society. A mobile health service is a type of health informatics that provides personalized healthcare advice to those who require it, especially the older people and the middle-aged. However, few studies consider the adoption of mobile health services with regard to older and middle-aged users. This paper explored a research model based on the value attitude behavior model, theory of planned behavior, and four aging characteristic constructs to investigate how older and middle-aged citizens adopted mobile health services. The hypothesized model was empirically tested using data collected from a survey of 424 residents older than 40 years in China. Structural equation modeling was used to estimate the significance of the path coefficients. The findings revealed that (1) perceived value, attitude, perceived behavior control, and resistance to change can be used to predict intention to use mobile health services for the middle-aged group; (2) perceived value, attitude, perceived behavior control, technology anxiety, and self-actualization need positively affected the behavior intention of older users; and (3) subjective norm and perceived physical condition showed no significant effects on the behavior intention to use mobile health services for the two groups. The theoretical and practical implications and contributions of this study are then discussed. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Despite the accumulated knowledge on moral decision-making in the early stages of development, empirical evidence is still limited in the old-aged adults. The current study contributes to unveil the neural correlates of judgments of moral transgressions as a function of aging, by examining the temporal dynamics of neural activation elicited by intentional and accidental harmful actions in three groups of healthy participants: young adults (18-35), adults (40-55), and older adults (60-75). Older adults were slower and less accurate in rating intentionality, compared to the younger groups. In ERP analysis, the older group showed increased P2 amplitude, which was predicted by poorer performance on neuropsychological tests. Reduced amplitudes were found on critical ERP components to moral cognition (N2 and LPP), namely while processing intentional harmful scenarios. Older adults seem to allocate more attentional resources (P2) to the task, probably to compensate the age-related decline in executive functioning, while younger groups show a pronounced negativity while detecting harm (N2) and increased neural activation to encode the intentions behind the acts (LPP).

[Demography and age-dependency in ophthalmic diseases].

Wolfram, C

2015-01-01

This article explains key terms in demography and describes current and future changes in the composition of the German population. The ratio of older persons is greatly increasing as age groups from higher birth rates are growing older and as the life expectancy continues to rise particularly for older age groups. Ophthalmology is highly affected by these societal changes as eye diseases particularly affect the elderly. The prevalence of blindness and low vision is increasing in the older population even though this increase is being overlapped by a general reduction in the risk of blindness. Up to more than 30% more age-related eye diseases are expected in the population by the year 2030, which will lead to an additional roughly 7.7 million ophthalmic consultations in the population of more than 60 years of age. The healthcare units need to be adjusted to the rising demand for ophthalmic care.

It is recommended to correct intravenous induction doses by up to 50% for patients older than 65 years. The objectives were to determine (a) the degree to which anesthesia providers correct induction doses for age and (b) additionally adjust for American Society of Anesthesiologists physical status (ASA-PS) class (severity of illness) and (c) whether postinduction hypotension is more common among patients aged >65. Retrospective chart review. Academic medical center. A total of 1869 adult patients receiving general anesthesia for GI surgical procedures from February 2013 to January 2014. Patients were divided into 3 age groups (age <65, 65-79, ≥80 years) and then further stratified into ASA-PS class (I/II vs III/IV). Multiple pairwise comparisons were conducted using Welch t tests for continuous variables to determine whether dosing was different for the older groups vs the younger group; separate analyses were performed within and across ASA-PS class. This approach was also used to determine differences in mean arterial pressure change in the older groups vs the younger group, whereas the rates of hypotension among different age groups were compared by Cochran-Armitage trend test. No significant decrease in dosing between age groups was observed for fentanyl and midazolam. For propofol, there was a significantly lower dosing for older patients: 17% for patients aged 65-79 and 29% for those aged >80, which was still in less than the recommendations. An inverse relationship was observed between propofol dosing and ASA-PS class, but no consistent relationship was noted for fentanyl and midazolam. There were a significantly larger drop in mean arterial pressure and a greater likelihood of hypotension following induction in patients aged 65-79 years and >80 years as compared with those aged <65 years. This study shows that the administered dose of anesthetic induction agents is significantly higher than that recommended for patients older than 65 years. This failure to age-adjust dose may contribute to hypotensive episodes. Copyright © 2016 Elsevier Inc. All rights reserved.

Age-related perspectives and emotion processing.

Emotion is processed differently in younger and older adults. Older adults show a positivity effect, whereas younger adults show a negativity effect. Socioemotional selectivity theory suggests that these effects can be elicited in any age group when age-related perspectives are manipulated. To examine this, younger and older adults were oriented to actual and age-contrasting possible selves. Emotion activations were assessed using lexical decision. In line with socioemotional selectivity theory, shifts in emotion orientation varied according to perspective, with both younger and older adults showing a negativity effect when a younger adult perspective was taken and a positivity effect when an older adult perspective was taken. 2013 APA, all rights reserved

This cross-sectional study investigated the age-related differences in dual-task performance both in mobility and cognitive tasks and the additive dual-task costs in a sample of older, middle-aged and young adults. 74 older adults (M = 72.63±5.57 years), 58 middle-aged adults (M = 46.69±4.68 years) and 63 young adults (M = 25.34±3.00 years) participated in the study. Participants performed different mobility and subtraction tasks under both single- and dual-task conditions. Linear regressions, repeated-measures and one-way analyses of covariance were used, The results showed: significant effects of the age on the dual and mobility tasks (p<0.05) and differences among the age-groups in the combined dual-task costs (p<0.05); significant decreases in mobility performance under dual-task conditions in all groups (p<0.05) and a decrease in cognitive performance in the older group (p<0.05). Dual-task activity affected mobility and cognitive performance, especially in older adults who showed a higher dual-task cost, suggesting that dual-tasks activities are affected by the age and consequently also mobility and cognitive tasks are negatively influenced.

We examined the effects of aging on visuo-spatial attention. Participants performed a bi-field visual selective attention task consisting of infrequent target and task-irrelevant novel stimuli randomly embedded among repeated standards in either attended or unattended visual fields. Blood oxygenation level dependent (BOLD) responses to the different classes of stimuli were measured using functional magnetic resonance imaging. The older group had slower reaction times to targets, and committed more false alarms but had comparable detection accuracy to young controls. Attended target and novel stimuli activated comparable widely distributed attention networks, including anterior and posterior association cortex, in both groups. The older group had reduced spatial extent of activation in several regions, including prefrontal, basal ganglia, and visual processing areas. In particular, the anterior cingulate and superior frontal gyrus showed more restricted activation in older compared with young adults across all attentional conditions and stimulus categories. The spatial extent of activations correlated with task performance in both age groups, but the regional pattern of association between hemodynamic responses and behavior differed between the groups. Whereas the young subjects relied on posterior regions, the older subjects engaged frontal areas. The results indicate that aging alters the functioning of neural networks subserving visual attention, and that these changes are related to cognitive performance.

Our study tested the hypothesis that older adults and men use more adaptive emotion regulatory strategies but fewer negative emotion regulatory strategies than younger adults and women. In addition, we tested the hypothesis that rumination acts as a mediator variable for the effect of age and gender on depression scores. Differences in rumination, problem solving, distraction, autobiographical recall and depression were assessed in a group of young adults (18-29 years) compared to a group of older adults (50-76 years). The older group used more problem solving and distraction strategies when in a depressed state than their younger counterparts (ps .06). Ordinary least squares regression analyses with bootstrapping showed that rumination mediated the association between age, gender and depression scores. These results suggest that older adults and men select more adaptive strategies to regulate emotions than young adults and women with rumination acting as a significant mediator variable in the association between age, gender, and depression.

Decreased independence and loss of functional ability are issues regarded as inevitably connected to old age. This ageism may have negative influences on older adults' beliefs about aging, making it difficult for them to focus on their current ability to maintain a good health. It is therefore important to change focus towards promoting Optimal Functionality (OF). OF is a concept putting the older adult's perspective on health and function in focus, however, the concept is still under development. Hence, the aim was to extend the concept of optimal functionality in various groups of older adults. A qualitative study was conducted based on focus group discussions (FGD). In total 6 FGDs were performed, including 37 older adults from three different groups: group 1) senior athletes, group 2) free living older adults, group 3) older adults living in senior living homes. All data was transcribed verbatim and analyzed following the process of deductive content analysis. The principal outcome of the analysis was "to function as optimally as you possibly can", which was perceived as the core of the concept. Further, the concept of OF was described as multifactorial and several new factors could be added to the original model of OF. Additionally the findings of the study support that all three cornerstones comprising OF have to occur simultaneously in order for the older adult to function as optimal as possible. OF is a multifaceted and subjective concept, which should be individually defined by the older adult. This study further makes evident that older adults as a group are heterogeneous in terms of their preferences and views on health and should thus be approached as such in the health care setting. Therefore it is important to promote an individualized approach as a base when caring for older adults.

Our aims were to determine acute myocardial infarction (AMI) incidence and mortality rates, and population and in-hospital case-fatality in the population older than 74 years; variability in clinical characteristics and AMI management of hospitalized patients, and changes in the incidence and mortality rates, case-fatality, and management by age groups from 1996 to 1997 and 2007 to 2008. A population-based AMI registry in Girona (Catalonia, Spain) including individuals with suspected AMI older than 34 years. The incidence rate increased with age from 169 and 28 cases/100 000 per year in the group aged 35 to 64 years to 2306 and 1384 cases/100 000 per year in the group aged 85 to 94 years, in men and women, respectively. Population case-fatality also increased with age, from 19% in the group aged 35 to 64 years to 84% in the group aged 85 to 94 years. A lower population case-fatality was observed in the second period, mainly explained by a lower in-hospital case-fatality. The use of invasive procedures and effective drugs decreased with age but increased in the second period in all ages up to 84 years. Acute myocardial infarction incidence, mortality, and case-fatality increased exponentially with age. There is still a gap in the use of invasive procedures and effective drugs between younger and older patients. Copyright © 2017 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U.

Although the major part of the burden of disease for female breast cancer occurs at older age, less is known about the development and progression in this age group than in women under 60 years of age. As the world population continues to age, the percentage of elderly is increasing in all communities and the incidence of breast cancer will rise accordingly. Improving detection and diagnosis, and a better understanding of the mechanisms that play a role in this age group, will not only improve quality of life in older sufferers but could also contribute to the management of this disease in the adult population as well. Development of breast cancer in the older woman is influenced by many variables that may differ from the risk factors that are involved in younger women. In addition to well-described variables at younger ages such as family history, hormonal exposure, lifestyle factors and pre-existing benign breast disease, in older women age-related changes in breast tissue, biochemistry, inflammatory responses and the immune system, as well as accumulation of DNA damage and spontaneous mutations are suspected to contribute to the complex relationship between ageing and breast cancer. We review the available data on the role of age-related changes and genetic mutations in the development of breast cancer in older women as well as their effects on estrogen metabolism and free oxygen radical inactivation.

The Growth of Older Inmate Populations: How Population Aging Explains Rising Age at Admission.

PubMed

Luallen, Jeremy; Cutler, Christopher

2017-09-01

Older inmates are the fastest growing segment of the prison population; however, the reasons for this are not well understood. One explanation is that the general population is aging, driving prison age distributions to change. For this article, we study the role of population aging in prison growth by investigating how the baby boom phenomenon of post-World War II has contributed to the growth of older inmate populations. We identify the impact of population aging using simulation methods that explain prison growth as the combination of criminal justice processes. Overall, we find evidence that population aging has played a significant role in explaining the growth of older inmate populations, in particular among inmates aged between 50 and 64 years, contributing to as much as half of the observed increase in these groups since 2000. This finding stands in contrast to the notion that population aging has little explanatory power in describing the growth of prison populations and implies that older inmate groups are more sensitive to compositional changes in the general population. We argue that prediction-based modeling of prison growth should more seriously consider the impacts and consequences of demographic shifts among older prisoner populations. © The Author 2015.

The life expectancy of persons with Prader-Willi syndrome (PWS) has increased in recent years. Because of the paucity of reports on older persons with PWS, the natural history, the onset, and type of age-related problems are poorly understood. Twelve persons with a genetically confirmed diagnosis of PWS aged over 50 years are described (4 deletion; 8 mUPD). Data on physical, behavioral, psychiatric, and aging characteristics were collected through semi-structured interviews with the individuals with PWS and their main carers. Cardiovascular diseases, diabetes, dermatological, and orthopedic problems were common physical complaints in older people with PWS. Functioning in activities of daily living, psychological functioning, physical functions, and care dependence were substantially worse in the older age group (50+) compared to the control group (18-49 years). Seven out of eight persons with mUPD had a history of psychiatric illness. Behavioral problems were observed in the older age group. Given the combination of age-related physical morbidity, physical appearance, behavioral and psychiatric problems, and functional decline in our cohort, we hypothesize that premature aging occurs in PWS. The care for older people with PWS requires a lifespan approach that recognizes the presence, progression, and consequences of specific morbidity. Special medical surveillance of people with PWS from 40 years onwards would ensure that intervention and support is offered with respect to specific areas of decline at the earliest possible time.

The increasing number of older adults with blood-related disorders and the introduction of reduced-intensity conditioning regimens has led to increases in hematopoietic stem cell (HSC) transplantation among older adults and a corresponding increase in the age of siblings who donate HSCs to these patients. Data regarding the donation-related experiences of older donors are lacking. The Related Donor Safety Study aimed to examine/compare health-related quality of life (HRQoL) of older versus younger HSC donors. Sixty peripheral blood stem cell (PBSC) donors ages 18 to 60 years and 104 PBSC donors age >60 years completed validated questionnaires before donation and 4 weeks and 1 year after donation. Before donation, older donors had poorer general physical health (t = -3.27; P = .001) but better mental health (t = 2.11; P < .05). There were no age differences in multiple other donation-related factors. At 4 weeks after donation, there were no group differences in general physical/mental health, but older donors were less likely to report donation-related pain (t = -2.26; P < .05) and concerns (t = -3.38; P = .001). At both 4 weeks and 1 year after donation, there were no significant differences in the percentage of each age group feeling physically back to normal or in the number of days it took donors to feel completely well. There was no evidence that increasing age within the older donor group was associated with poorer donation-related HRQoL. Taken together, these data support the current practice of HSC donation by sibling donors above age 60, providing no evidence of worsening HRQoL up to 1 year after donation in individuals up to age 76.

In this report we demonstrate a hemodynamic scaling method with resting-state fluctuation of amplitude (RSFA) in healthy adult younger and older subject groups. We show that RSFA correlated with breath hold (BH) responses throughout the brain in groups of younger and older subjects, that RSFA and BH performed comparably in accounting for age-related hemodynamic coupling changes, and yielded more veridical estimates of age-related differences in task-related neural activity. BOLD data from younger and older adults performing motor and cognitive tasks were scaled using RSFA and BH related signal changes. Scaling with RSFA and BH reduced the skew of the BOLD response amplitude distribution in each subject and reduced mean BOLD amplitude and variability in both age groups. Statistically significant differences in intra-subject amplitude variation across regions of activated cortex, and inter-subject amplitude variation in regions of activated cortex were observed between younger and older subject groups. Intra- and inter-subject variability differences were mitigated after scaling. RSFA, though similar to BH in minimizing skew in the un-scaled BOLD amplitude distribution, attenuated the neural activity related BOLD amplitude significantly less than BH. The amplitude and spatial extent of group activation were lower in the older than in the younger group prior to and after scaling. After accounting for vascular variability differences through scaling, age-related decreases in activation volume were observed during the motor and cognitive tasks. The results suggest that RSFA-scaled data yield age-related neural activity differences during task performance with negligible effects from non-neural (i.e., vascular) sources. PMID:20665721

The aim of the study was to compare electromechanical response times [total reaction time (TRT), pre-motor time (PMT), and electromechanical delay] in the knee muscles in groups of young and older women during release of peak torque (PT). Fifty women (1 group approximately 20 years of age and the other approximately 60 years of age) participated in the study. PT and electromyographic activity were measured for flexors and extensors of the right and left knee in static conditions in response to a visual stimulus. Significantly longer TRTs (P = 0.05) and PMTs (P = 0.05) were found in the group of older women compared with the younger participants. Asymmetry was found between the older and the younger group of women in PT of knee flexors. Significantly longer TRT and PMT phases in the group of older women suggests a longer time for information processing in the central nervous system in older people.

Objective To clarify if older pregnant women were more likely to have adverse perinatal outcomes when compared to women at an ideal age to have a child. Methods The groups were divided according to age groups: under 20 years, ≥20 to <40 years, and ≥40 years. Results During the period from January 1st, 2008, to December 31st, 2008, there were 76 births from patients younger than 20 years and 91 births from patients aged 40 years or over. To form a third group with intermediate age, the data of 92 patients aged 20 to 40 years were obtained, totaling 259 patients. Patients aged 40 or older had a statistically greater number of cesarean sections and less use of forceps or normal deliveries (p<0.001). The use of spinal anesthesia was statistically higher among those aged 40 years or more (p<0.001). The frequency of male newborns was statistically higher in older patients, a group with statistically fewer first pregnancies (p<0.001). The frequency of premature newborns was statistically higher in patients aged 40 years or more (p=0.004). Conclusion It is crucial to give priority to aged women, so that prenatal care will be appropriate, minimizing maternal complications and improving perinatal outcomes in this unique group.

The purpose of this study was to compare the association between anti and pro-oxidant activity, nitrite concentration, and blood pressure (BP) in middle-aged and older women with different levels of estimated training status (TS). The sample consisted of 155 females (50–84 years) who were submitted to a physical examination to evaluate estimated TS through the “Functional Fitness Battery Test,” BP measurements, and plasma blood samples to evaluate pro-oxidant and antioxidant activity and nitrite concentrations. Participants were separated by age into a middle-aged group (<65 years) and an older (≥65 years) group and then subdivided in each group according to TS. Blood biochemistry was similar between groups. On the other hand, protein oxidation was lower in participants with higher TS, independent of age. Older females with higher TS presented higher nitrite concentrations, lower lipoperoxidation, and lower values of BP compared with those with lower TS. Lower GPx activity was observed in participants with higher TS compared with middle-aged with lower TS. Thus, our results suggest that good levels of TS may be associated with lower oxidative stress and higher nitrite concentration and may contribute to maintain normal or reduced blood pressure values.

The effects of aging on the neural correlates of subjective and objective recollection.

High-functioning older adults can exhibit normal recollection when measured subjectively, via "remember" judgments, but not when measured objectively, via source judgments, whereas low-functioning older adults exhibit impairments for both measures. A potential explanation for this is that typical subjective and objective tests of recollection necessitate different processing demands, supported by distinct brain regions, and that deficits in these tests are observed according to the degree of age-related changes in these regions. Here, we used event-related functional magnetic resonance imaging to measure the effects of aging on neural correlates of subjective and objective measures of recollection, in young, high-functioning (Old-High) and low-functioning (Old-Low) older adults. Behaviorally, the Old-High group showed intact subjective ("remember" judgments) but impaired objective recollection (for 1 of 2 spatial or temporal sources), whereas the Old-Low group was impaired on both measures. Imaging data showed changes in parietal subjective recollection effects in the Old-Low group and in lateral frontal objective recollection effects in both older adult groups. Our results highlight the importance of examining performance variability in older adults and suggest that differential effects of aging on brain regions are associated with different patterns of performance on tests of subjective and objective recollection.

Do age and extended culture affect the architecture of the zona pellucida of human oocytes and embryos?

Advanced female age and extended in vitro culture have both been implicated in zona pellucida (ZP) hardening and thickening. This study aimed to determine the influence of (i) the woman's age and (ii) prolonged in vitro culture of embryos on ZP thickness and density using non-invasive polarized light (LC-PolScope) microscopy. ZP thickness and density (measured as retardance) were determined in oocytes, embryos and blastocysts in women undergoing intracytoplasmic sperm injection (ICSI) in two age groups (older, > 38 years; younger, < or = 38 years). A total of 193 oocytes from 29 patients were studied. The younger group contained 100 oocytes and the older group 93 oocytes. The ZP was significantly thicker in metaphase II oocytes in the older group compared with the younger group (mean +/- SD: 24.1 +/- 2.5 microm vs 23.1 +/- 3.3 microm; p = 0.01) but ZP density was equal (2.8 +/- 0.7 nm). By day 2 of culture, embryos from the two groups had similar ZP thickness (22.2 +/- 2.2 microm vs 21.7 +/- 1.6 microm; p = 0.28) and density (2.9 +/- 0.7 nm vs 2.8 +/- 0.8 nm; p = 0.57). For the embryos cultured to blastocyst (older: n = 20; younger: n = 18) ZP thickness was similar in the two groups (19.2 +/- 2.7 microm vs 19.1 +/- 5.0 microm; p = 0.8) but thinner than on day 2. The older group had significantly denser ZP than the younger group (4.2 +/- 0.5 nm vs 3.3 +/- 1.0 nm, p < 0.01). Blastocysts from both groups had significantly denser ZP than their corresponding day 2 embryos (older: 4.2 +/- 0.5 nm vs 2.9 +/- 0.7 nm, p < 0.001; younger: 3.3 +/- 1.0 nm vs 2.8 +/- 0.8 nm, p = 0.013). It is concluded that there is little relationship between ZP thickness and its density as measured by polarized light microscopy. While ZP thickness decreases with extended embryo culturing, the density of the ZP increases. ZP density increases in both age groups with extended culture and, interestingly, more in embryos from older compared with younger women.

This study compared message-framing effects on physical activity (PA) across age and gender groups. Participants included 111 younger and 100 older adults (68% were women), randomly assigned to read gain-framed or loss-framed PA messages in promotion pamphlets, and who wore accelerometers for the following 14 days. Using regression analyses controlling for demographic and health factors, we found significant age-by-gender-by-framing interactions predicting self-report (B = -4.39, p = .01) and accelerometer-assessed PA (B = -2.44, p = .02) during the follow-up period. Gain-framed messages were more effective than loss-framed messages in promoting PA behaviors only among older men. We speculated that the age-related positivity effect, as well as the age and gender differences in issue involvement, explained the group differences in framing. In addition, more time availability and higher self-efficacy among older men might have contributed to the results.

This study investigated the impact of aging on audio-visual speech integration. A syllable identification task was presented in auditory-only, visual-only, and audio-visual congruent and incongruent conditions. Visual cues were either degraded or unmodified. Stimuli were embedded in stationary noise alternating with modulated noise. Fifteen young adults and 15 older adults participated in this study. Results showed that older adults had preserved lipreading abilities when the visual input was clear but not when it was degraded. The impact of aging on audio-visual integration also depended on the quality of the visual cues. In the visual clear condition, the audio-visual gain was similar in both groups and analyses in the framework of the fuzzy-logical model of perception confirmed that older adults did not differ from younger adults in their audio-visual integration abilities. In the visual reduction condition, the audio-visual gain was reduced in the older group, but only when the noise was stationary, suggesting that older participants could compensate for the loss of lipreading abilities by using the auditory information available in the valleys of the noise. The fuzzy-logical model of perception confirmed the significant impact of aging on audio-visual integration by showing an increased weight of audition in the older group.

Asthma affects more than two million Australians, and of growing concern for the Australian health system is asthma in the over 65+ age group. Between 1997 and 2001, 61% of all deaths attributable to asthma occurred in people aged over 65 and mortality in this group remains higher than the rate for all other groups. An investigation of older Australians' perceptions of asthma prevalence and impact was conducted in the Illawarra region of New South Wales. Eight focus groups with the target audience were conducted to explore their attitudes, knowledge and skills with regard to asthma symptoms, prevalence, diagnosis and treatment. Additionally, 12 in-depth interviews were conducted with a broad range of health professionals to ascertain their opinion of the target audience's asthma knowledge and understanding. Results indicate that these older Australians are unaware of the prevalence and severity of asthma in their age group, have limited understanding of symptoms and treatments, and associate the condition with children. Health professionals reported that older people minimise respiratory symptoms as a natural part of ageing. Qualitative analysis using the Health Belief Model, suggests that heightened knowledge and awareness is necessary to bring about voluntary behaviour change in order to reduce asthma mortality and morbidity in the 65+ age group.

Age related testosterone level changes and male andropause syndrome.

Much like the menopause syndrome occurring among older women, a similar condition has been defined among men. Testosterone production increases rapidly at the onset of puberty, then dwindles quickly after age 50 to become 20 to 50% of the peak level by age 80. Many men older than age 50 have experienced frailty syndrome, which includes decrease of libido, easy fatigue, mood disturbance, accelerated osteoporosis, and decreased muscle strength. We investigated serum total testosterone levels and andropause syndrome in men. Serum total testosterone levels were measured in 53 symptomatic men older than age 50 and in 48 men younger than age 40 for a control group. We also analyzed andropause symptoms among the 53 men older than age 50. The mean serum total testosterone level in the symptomatic men older than age 50 (mean: 2.68 +/- 0.51 ng/ml, range: 1.21 to 4.13 ng/ml) was significantly lower than that in the control group (mean: 7.01 +/- 0.82 ng/ml, range: 5.53 ng/ml to 8.14 ng/ml). Male frailty syndrome in these men older than 50 included: decreased libido (91%), lack of energy (89%), erection problems (79%), falling asleep after dinner (77%), memory impairment (77%), loss of pubic hair (70%), sad or grumpy mood changes (68%), decrease in endurance (66%), loss of axillary hair (55%), and deterioration in work performance (51%). The serum total testosterone level showed a decline with aging, especially in the men older than age 50. Low serum testosterone levels were also associated with the symptoms of male andropause syndrome.

Factors important for avoiding back disorders in different age-groups have seldom been compared and studied over time. We therefore set out to study age-related differences in socio-economic and work-related factors associated with the absence of back disorders in a 5-year comparative cohort study using a mailed questionnaire. Two subgroups (aged 25-34 and 54-59 years) derived from a representative sample of the Swedish population were followed at baseline, 1 year and 5 years. Questions were asked about the duration of back pain episodes, relapses, work changes and work satisfaction. A work adaptability, partnership, growth, affection, resolve (APGAR) score was included in the final questionnaire. Multivariate logistic regression was used to identify factors predicting the absence of back disorders. Absence of physically heavy work predicted an absence of back disorders [odds ratio (OR), 2.86; 95% confidence interval (CI), 1.3-6.3] in the older group. In the younger age-group, the absence of stressful work predicted absence of back disorders (OR, 2.0; 95% CI, 1.1-3.6). Thirty-seven per cent of the younger age-group and 43% of the older age-group did not experience any back pain episodes during the study period. The exploratory work APGAR scores indicated that back disorders were only associated with lower work satisfaction in the older group. The analyses point out the importance of avoiding perceived psychological stress in the young and avoiding perceived physically heavy work in the older age-group for avoiding back disorders. The results suggest a need for different programmes at workplaces to avoid back disorders depending on the age of the employees concerned.

Acquisition of numerical knowledge and understanding of numerical information are crucial for coping with the changing demands of our digital society. In this study, we assessed arithmetic learning in older and younger individuals in a training experiment including brain imaging. In particular, we assessed age-related effects of training intensity, prior arithmetic competence, and neuropsychological variables on the acquisition of new arithmetic knowledge and on the transfer to new, unknown problems. Effects were assessed immediately after training and after 3 months. Behavioural results showed higher training effects for younger individuals than for older individuals and significantly better performance after 90 problem repetitions than after 30 repetitions in both age groups. A correlation analysis indicated that older adults with lower memory and executive functions at baseline could profit more from intensive training. Similarly, training effects in the younger group were higher for those individuals who had lower arithmetic competence and executive functions prior to intervention. In younger adults, successful transfer was associated with higher executive functions. Memory and set-shifting emerged as significant predictors of training effects in the older group. For the younger group, prior arithmetic competence was a significant predictor of training effects, while cognitive flexibility was a predictor of transfer effects. After training, a subgroup of participants underwent an MRI assessment. A voxel-based morphometry analysis showed a significant interaction between training effects and grey matter volume of the right middle temporal gyrus extending to the angular gyrus for the younger group relative to the older group. The reverse contrast (older group vs. younger group) did not yield any significant results. These results suggest that improvements in arithmetic competence are supported by temporo-parietal areas in the right hemisphere in younger participants, while learning in older people might be more widespread. Overall, our study indicates that arithmetic learning depends on the training intensity as well as on person-related factors including individual age, arithmetic competence before training, memory, and executive functions. In conclusion, we suggest that major progress can be also achieved by older participants, but that interventions have to take into account individual variables in order to provide maximal benefit.

Previous retrospective studies have shown that physical functioning in older cancer survivors is affected after treatment, yet prospective data are lacking. The aim of this study was to assess change in physical functioning in different age groups of patients with hormone receptor-positive breast cancer who were enrolled in the Tamoxifen Exemestane Adjuvant Multinational (TEAM) phase III trial. Two physical parameters were assessed. Physical functioning was assessed using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire 1 year (T1) and 2 years (T2) after diagnosis. Physical activity was measured in metabolic equivalent of task (MET) hours/week at T1 and T2. Physical activity before diagnosis (T0) was assessed retrospectively at the T1 questionnaire. Patients were divided into three age groups: <60, 60-69, and ≥70 years. Decline in physical functioning was assessed using linear regression analysis. Differences in mean values of physical activity levels were calculated using repeated-measures one-way analysis of variance. A total of 431 patients were included for analysis. In all age groups, physical activity levels at T1 and T2 were significantly lower than prediagnostic physical activity levels (T0) (p < .001 for all age groups). Age ≥70 years was independently associated with decline in physical functioning between T1 and T2 (β = -4.62, 95% confidence interval -8.73 to -0.51, p = .028). Patients aged 70 years or older treated with breast surgery and adjuvant hormonal therapy did not improve between years 1 and 2 after diagnosis to the same extent as did younger patients. Although older patients constitute a large share of the breast cancer population, little is known about the effect and consequences of treatment of breast cancer in this specific age group. This study revealed that, unlike younger patients, older patients do not regain their physical abilities after surgical and adjuvant treatment for breast cancer. In older adults, the effect of treatment on physical functioning and independency could be more relevant than survival outcomes. Clinicians and older patients should be aware of the impact of treatment on physical functioning and prevent older patients from experiencing physical decline, which could lead to institutionalization and loss of independence. There is a need for age-specific guidelines that take into account the heterogeneity of the older population and for evidence-based treatment that focuses not only on cancer-specific outcomes but also on the consequences of treatment for physical and cognitive functioning and quality of life. ©AlphaMed Press.

Evidence-based recommendations for optimal dietary protein intake in older people: a position paper from the PROT-AGE Study Group.

New evidence shows that older adults need more dietary protein than do younger adults to support good health, promote recovery from illness, and maintain functionality. Older people need to make up for age-related changes in protein metabolism, such as high splanchnic extraction and declining anabolic responses to ingested protein. They also need more protein to offset inflammatory and catabolic conditions associated with chronic and acute diseases that occur commonly with aging. With the goal of developing updated, evidence-based recommendations for optimal protein intake by older people, the European Union Geriatric Medicine Society (EUGMS), in cooperation with other scientific organizations, appointed an international study group to review dietary protein needs with aging (PROT-AGE Study Group). To help older people (>65 years) maintain and regain lean body mass and function, the PROT-AGE study group recommends average daily intake at least in the range of 1.0 to 1.2 g protein per kilogram of body weight per day. Both endurance- and resistance-type exercises are recommended at individualized levels that are safe and tolerated, and higher protein intake (ie, ≥ 1.2 g/kg body weight/d) is advised for those who are exercising and otherwise active. Most older adults who have acute or chronic diseases need even more dietary protein (ie, 1.2-1.5 g/kg body weight/d). Older people with severe kidney disease (ie, estimated GFR <30 mL/min/1.73 m(2)), but who are not on dialysis, are an exception to this rule; these individuals may need to limit protein intake. Protein quality, timing of ingestion, and intake of other nutritional supplements may be relevant, but evidence is not yet sufficient to support specific recommendations. Older people are vulnerable to losses in physical function capacity, and such losses predict loss of independence, falls, and even mortality. Thus, future studies aimed at pinpointing optimal protein intake in specific populations of older people need to include measures of physical function.

European societies are rapidly ageing and becoming multicultural. We studied differences in overall and cause-specific mortality between migrants and non-migrants in Belgium specifically focusing on the older population. We performed a mortality follow-up until 2009 of the population aged 50 and over living in Flanders and the Brussels-Capital Region by linking the 2001 census data with the population and mortality registers. Overall mortality differences were analysed via directly age-standardized mortality rates. Cause-specific mortality differences between non-migrants and various western and non-western migrant groups were analysed using Poisson regression models, controlling for age (model 1) and additionally controlling for socio-economic status and urban typology (model 2). At older ages, most migrants had an overall mortality advantage relative to non-migrants, regardless of a lower socio-economic status. Specific migrant groups (e.g. Turkish migrants, French and eastern European male migrants and German female migrants) had an overall mortality disadvantage, which was, at least partially, attributable to a lower socio-economic status. Despite the general overall mortality advantage, migrants experienced higher mortality from infectious diseases, diabetes-related causes, respiratory diseases (western migrants), cardiovascular diseases (non-western female migrants) and lung cancer (western female migrants). Mortality differences between older migrants and non-migrants depend on cause of death, age, sex, migrant origin and socio-economic status. These differences can be related to lifestyle, social networks and health care use. Policies aimed at reducing mortality inequalities between older migrants and non-migrants should address the specific health needs of the various migrant groups, as well as socio-economic disparities. © The Author 2016.

Globally, increasing numbers of HIV-infected children are reaching adolescence due to antiretroviral therapy (ART). We investigated rates of loss-to-follow-up (LTFU) from HIV care services among children as they transition from childhood through adolescence. Individuals aged 5-19 years initiated on ART in a public-sector HIV clinic in Bulawayo, Zimbabwe, between 2005 and 2009 were included in a retrospective cohort study. Participants were categorized into narrow age-bands namely: 5-9 (children), 10-14 (young adolescents) and 15-19 (older adolescents). The effect of age at ART initiation, current age (using a time-updated Lexis expansion) and transitioning from one age group to the next on LTFU was estimated using Poisson regression. Of 2273 participants, 1013, 875 and 385 initiated ART aged 5-9, 10-14 and 15-19 years, respectively. Unlike those starting ART as children, individuals starting ART as young adolescents had higher LTFU rates after moving to the older adolescent age-band (Adjusted rate ratio (ARR) 1.54; 95% CI: 0.94-2.55) and similarly, older adolescents had higher LTFU rates after transitioning to being young adults (ARR 1.79; 95% CI: 1.05-3.07). In older adolescents, the LTFU rate among those who started ART in that age-band was higher compared to the rate among those starting ART at a younger age (ARR = 1.70; 95% CI: 1.05, 2.77). This however did not hold true for other age-groups. Adolescents had higher rates of LTFU compared to other age-groups, with older adolescents at particularly high risk in all analyses. Age-updated analyses that examine movement across narrow age-bands are paramount in understanding how developmental heterogeneity in children affects HIV outcomes.

The prevalence of age-related cognitive decline will increase due to graying of the global population. The goal of the present study was to test whether playing online cognitive training games can improve cognitive control (CC) in healthy older adults. Fifty-four older adults (age 60-77) played five different cognitive training games online for 30 min a day over a period of seven weeks (game group). Another group of 20 older adults (age 61-73) instead answered quiz questions about documentaries online (documentary group). Transfer was assessed by means of a cognitive test battery administered before and after the intervention. The test battery included measures of working memory updating, set shifting, response inhibition, attention, and inductive reasoning. Compared with the documentary group, the game group showed larger improvement of inhibition (Stop-Signal task) and inductive reasoning (Raven-SPM), whereas the documentary group showed more improvement in selective attention (UFoV-3). These effects qualify as transfer effects, because response inhibition, inductive reasoning and selective attention were not targeted by the interventions. However, because seven other indicators of CC did not show benefits of game training and some of those that did suffered from potential baseline differences, the study as a whole provides only modest support for the potential of videogame training to improve CC in healthy older adults.

Rapidly growing research reveals complex yet systematic consequences of collaboration on memory in young adults, but much less is known about this phenomenon in older adults. Young and older adults studied a list of categorized words and took three successive recall tests. Test 1 and 3 were always taken individually, and Test 2 was done either in triads or alone. Despite older adults recalling less overall than young adults, both age groups exhibited similar costs and benefits of collaboration: Collaboration reduced both correct and false recall during collaborative remembering, was associated with more positive beliefs about its value, and produced reminiscence, collective memory, and some forgetting in its cascading effects on postcollaborative recall. We examine the role of retrieval organization in these effects. As environmental support may play a substantial role in healthy aging, the relatively preserved effects of collaboration on memory in older adults hold promise for testing judicious uses of group remembering in aging.

Studies show that as we enter older adulthood (>64years), our ability to mentally represent action in the form of using motor imagery declines. Using a chronometry paradigm to compare the movement duration of imagined and executed movements, we tested young-, middle-aged, and older adults on their ability to perform sequential finger (fine-motor) movements. The task required number recognition and ordering and was presented in three levels of complexity. Results for movement duration indicated no differences between young- and middle-aged adults, however both performed faster than the older group. In regard to the association between imagined and executed actions, correlation analyses indicated that values for all groups were positive and moderate (r's .80,.76,.70). In summary, whereas the older adults were significantly slower in processing actions than their younger counterparts, the ability to mentally represent their actions was similar.

The aim of this study was to determine reference physical performance values in older aging workers. Cross-sectional physical performance measures were collected for 736 manufacturing workers to assess effects of work and nonwork factors on age-related changes in musculoskeletal function and health. Participants underwent surveys and physical testing that included bioelectrical impedance analysis, range-of-motion measures, exercise testing, and dynamic assessment. Physical characteristics, such as blood pressure and body fat percentage, were comparable to published values. Dynamic and range-of-motion measurements differed from published normative results. Women had age-related decreases in cervical extension and lateral rotation. Older men had better spinal flexion than expected. Predicted age-related decline in lower-extremity strength and shoulder strength in women was not seen. Men declined in handgrip, lower-extremity strength, and knee extension strength, but not trunk strength, across age groups. There was no appreciable decline in muscle fatigue at the trunk, shoulder, and knee with aging for either gender, except for the youngest age group of women. Normative values may underestimate physical performance in "healthy" older workers, thereby underappreciating declines in less healthy older workers. Work may be preservative of function for a large group of selected individuals. A "healthy worker effect" may be greater for musculoskeletal disease and function than for heart disease and mortality. Clinicians and researchers studying musculoskeletal function in older workers can use a more specific set of reference values.

Previous research on age-related changes in Theory of Mind (ToM) showed a decline in older adults, particularly pronounced over 75 years of age. Evidence that ToM may be enhanced in healthy aging people has been demonstrated, but no study has focused on the role of age on the effects of ToM training for elderly people. The present study was designed to examine the efficacy of a ToM training on practiced (ToM Strange Stories) and transfer tasks (ToM Animations) in both young and older adults. The study involved 127 older adults belonging to two age groups: young-old (Mage = 64.41; SD = 2.49; range: 60-69 years) and old-old (Mage = 75.66; SD = 4.38; range: 70-85 years), randomly assigned to either a ToM group or a control group condition. All participants took part in two 2-hour testing sessions and four 2-hour training sessions. Results showed that both young-old and old-old adults in the ToM group condition improved their ability to reason on complex-mental states significantly more than participants in the control group condition. This positive effect of the training was evident on practiced and transfer ToM tasks. Crucially, age did not moderate the effect of the ToM training. These findings demonstrate that young-old and old-old adults equally benefit from the ToM training. Implications for the positive effect of the ToM training in old-old adults are discussed.

Religiosity has been shown to be inversely associated with suicidal ideation, but few studies have examined associations by age group. This study aimed to examine the association between religiosity with suicidal ideation by age group. This study used a large nationally representative sample of 260,816 study participants from the National Survey on Drug Use and Health. Religiosity was defined as self-reported importance of religious beliefs and frequency of religious service attendance. The association between religiosity and suicidal ideation was assessed by multivariable logistic regression analysis stratified by age group (18-25, 26-34, 35-49, 50-64, 65 or older). The importance of religious beliefs was inversely associated with suicidal ideation in all age groups. The association was the strongest in people aged 65 or older, followed by people aged 18-25. Religious service attendance was also inversely associated with suicidal ideation in people aged 65 or more when attendance was more than 25 times per year. These findings may be helpful to understand age in relation to the relationship between religiosity and suicidal ideation. Particular attention to religiosity among older adults as a protective factor for suicidal ideation may be helpful in clinical settings. Copyright © 2017. Published by Elsevier B.V.

Active ageing is one of the most important issues taken up by the WHO in regard to ageing societies. "Prolonging Healthy Life Expectance" and "Decreasing the Depression Rate Among Older People" are critical indicators for "2020 Healthy People in Taiwan". This paper conducts a trial run of the program planning and evaluation of mental-social health promotion using focus group research that surveys 29 administrative districts and a depression survey that randomly samples older individuals in Taichung City. We also introduce how we apply local characteristics to develop the 3-level and innovative-action plans to meet the needs of self-identity and social participation for older people. For example, the "Learning Mobile Classroom" program promotes health promotion using activities that are tailored to the lifestyle and culture characteristics of target individuals. Another example is the "Seniors Show", which uses community groups and annual active-ageing shows to promote a positive concept of aging and to promote social participation for older people. Finally, the "Navigator APP of Active Ageing", created using a geographic information system, addresses the resource information needs of older people. This experience in Taichung City uniquely empowers older people, allowing them to take the initiative to make a difference not only for mental-social wellness but also for the hope of life and for graceful ageing.

Audiological data from a population based epidemiological investigation were studied on elderly persons. Specific diagnoses of otological and audiological disorders, which can result in hearing loss, were searched for. A retrospective register study. Three age cohorts, 474 70- and 75-year olds ("younger"), and 252 85-year olds ("older"), were studied. Clinical pure tone and speech audiometry was used. Data from medical files were included. Conductive hearing loss was diagnosed in 6.1% of the "younger" elderly persons, and in 10.3% of the "older" ones. Specific diagnoses (chronic otitis media and otosclerosis) were established in about half of the cases. Sensorineural hearing loss, other than age-related hearing loss and noise induced hearing loss, was diagnosed in 3.4 % and 5.2% respectively. Severely impaired speech recognition, possibly reflecting age-related auditory neuropathy, was found in 0.4% in the "younger" group, and in 10% in the "older" group. Bilateral functional deafness was present in 3.2% of the 85-year-old persons, but was not present in the 70-75-year group. The incidence of probable age-related auditory neuropathy increases considerably from 70-75 to 85 years. There are marked differences between "younger" and "older" elderly persons regarding hearing loss that severely affects oral communication.

Abstract Individuals 65 years of age and over have the highest rates of traumatic brain injury (TBI)-related hospitalizations and deaths, and older adults (defined variably across studies) have particularly poor outcomes after TBI. The factors predicting these outcomes remain poorly understood, and age-specific care guidelines for TBI do not exist. This study provides an overview of TBI in older adults using data from the National Trauma Data Bank (NTDB) gathered between 2007 and 2010, evaluates age group-specific trends in rates of TBI over time using U.S. Census data, and examines whether routinely collected information is able to predict hospital discharge status among older adults with TBI in the NTDB. Results showed a 20–25% increase in trauma center admissions for TBI among the oldest age groups (those >=75 years), relative to the general population, between 2007 and 2010. Older adults (>=65 years) with TBI tended to be white females who have incurred an injury from a fall resulting in a “severe” Abbreviated Injury Scale (AIS) score of the head. Older adults had more in-hospital procedures, such as neuroimaging and neurosurgery, tended to experience longer hospital stays, and were more likely to require continued medical care than younger adults. Older age, injury severity, and hypotension increased the odds of in-hospital death. The public health burden of TBI among older adults will likely increase as the Baby Boom generation ages. Improved primary and secondary prevention of TBI in this cohort is needed. PMID:23962046

A reduction in number and function of endothelial progenitor cells (EPCs) occurs in both physiologic aging and chronic heart failure (CHF). We assessed whether disease and aging have additive effects on EPCs or whether beneficial effects of exercise training are diminished in old age. We randomized 60 patients with stable CHF and 60 referent controls to a training or a control group. To detect possible aging effects we included subjects below 55 (young) and above 65 years (older). Subjects in the training group exercised four times daily at 60% to 70% of VO2max for four weeks under supervision. At baseline and after the intervention the number and function of EPCs were assessed. As compared with young referent controls, older referent controls showed at baseline a reduced EPC number (young: 190 ± 37 CD34/KDR positive cells/ml blood; older: 131 ± 26 CD34/KDR positive cells/ml blood; p < 0.05) and function (young: 230 ± 41 migrated cells/1000 plated cells; older: 185 ± 28 cells/1000 plated cells; p < 0.05). In young and older CHF patients EPC-number (young: 85 ± 21 CD34/KDR positive cells/ml blood; older: 78 ± 20 CD34/KDR positive cells/ml blood) and EPC-function (young: 113 ± 26 cells/1000 plated cells; older: 120 ± 27 cells/1000 plated cells) were impaired. As a result of exercise training, EPC function improved by 24% in older referent controls (p < 0.05), while it remained unchanged in young training referent controls and controls respectively. In young and older patients with CHF four weeks of exercise training resulted in a significant improvement in EPC numbers and EPC function (young: number +66% function +43%; p < 0.05; older: number +69% function +36%; p < 0.05). These results were accompanied by a significant increase in flow mediated dilatation in the training groups of young/older CHF patients and in older referent controls. Four weeks of exercise training are effective in improving EPC number and EPC function in CHF patients. These training effects were not impaired among older patients, emphasizing the potentials of rehabilitation interventions in a patient group where CHF has a high prevalence. © The European Society of Cardiology 2015.

Lower limb mobility disabilities are well understood in older people, but the causes in middle age have attracted little attention. To estimate the prevalence of mobility disabilities among noninstitutionalized adults in England and to compare the disabling symptoms reported by middle-aged and older people. Cross-sectional data from the 2002 English Longitudinal Study of Ageing (ELSA). Mobility disability was identified by level of reported difficulty walking a quarter mile. Eleven thousand two hundred sixteen respondents aged 50 years and older living in private households in 2002. The prevalence of difficulty walking a quarter mile increases sharply with age, but even in the middle-aged (50 to 64 years age-group) 18% (95% confidence interval [CI]: 16% to 19%) of men and 19% (95% CI: 17% to 20%) of women reported some degree of difficulty. Of the 16 main symptoms reported as causing mobility disability in middle age, 2 dominated: pain in the leg or the foot (43%; 95% CI: 40% to 46%) and shortness of breath/dyspnea (21%; 95% CI: 18% to 23%). Fatigue or tiredness, and stability problems were cited by only 5% and 6%, respectively. These proportions were slightly different from those in the 65 to 79-year age group: 40%, 23%, 6%, and 8%, respectively. Mobility (walking) disabilities in the middle-aged are relatively common. The symptoms reported as causes in this age group differ little from those reported by older groups, and are dominated by lower limb pain and shortness of breath. More clinical attention paid to disabling symptoms may lead to disability reductions in later life.

Age differences in the takeover of vehicle control and engagement in non-driving-related activities in simulated driving with conditional automation.

2017-09-01

High-level vehicle automation has been proposed as a valuable means to enhance the mobility of older drivers, as older drivers experience age-related declines in many cognitive functions that are vital for safe driving. Recent research attempted to examine age differences in how engagement in non-driving-related activities impact driving performance, by instructing drivers to engage in mandatory pre-designed activities. While the mandatory engagement method allows a precise control of the timing and mental workload of the non-driving-related activities, it is different from how a driver would naturally engage in these activities. This study allowed younger (age 18-35, mean age=19.9years) and older drivers (age 62-81, mean age=70.4years) to freely decide when and how to engage in voluntarily chosen non-driving-related activities during simulated driving with conditional automation. We coded video recordings of participants' engagement in non-driving-related activities. We examined the effect of age, level of activity-engagement and takeover notification interval on vehicle control performance during the takeover, by comparing between the high and low engagement groups in younger and older drivers, across two takeover notification interval conditions. We found that both younger and older drivers engaged in various non-driving-related activities during the automated driving portion, with distinct preferences on the type of activity for each age group (i.e., while younger drivers mostly used an electronic device, older drivers tended to converse). There were also significant differences between the two age groups and between the two notification intervals on various driving performance measures. Older drivers benefited more than younger drivers from the longer interval in terms of response time to notifications. Voluntary engagement in non-driving-related activities did not impair takeover performance in general, although there was a trend of older drivers who were more engaged in non-driving-related activities braking harder than those with low activity-engagement during the takeover.

To examine differences in factors associated with contraceptive use between younger and older adolescent age groups, which has not previously been well described. Age group-specific analyses were performed on cross-sectional survey data to identify factors associated with any contraceptive use at last sex among younger (14- to 16-year-old) and older (17- to 19-year-old) sexually active African American female adolescents; interaction analyses were used to assess whether these associations differed by age. Adolescent reproductive health clinic in Atlanta, Georgia. Sexually active African American female adolescents 14-19 years of age. No intervention tested; cross-sectional design. Self-reported contraceptive use during most recent vaginal sex with a male partner. The prevalence of contraceptive use at last sex was identical in both groups; however, factors associated with contraceptive use differed according to age. The only factor associated with contraceptive use in both age groups was involvement in decisions about sexual health in the most recent relationship. Associations between factors and contraceptive use significantly differed according to age. History of sexually transmitted infection, age difference with partner, discussion of condoms with partner, and concurrent partners were important factors among younger adolescents; worry about pregnancy and discussion of birth control with partner were important among older adolescents. Factors associated with contraceptive use at last sex differ according to adolescent age; this should be considered when designing counseling and interventions for teens, as well as research.

Simultaneous performances of motor and attention-demanding tasks are common in activities of everyday life. The present cross-sectional study examined the changes and age-related differences on mobility performance with an additional cognitive or motor task, and evaluated the relative dual-task cost (DTC) on the motor performance in young, middle-aged and older women. A total of 30 young (mean age 25.12 ± 3.00 years), 30 middle-aged (mean age 47.82 ± 5.06 years) and 30 older women (mean age 72.74 ± 5.95 years) were recruited. Participants carried out: (i) single task: Timed Up & Go Test; (ii) cognitive dual-task: Timed Up & Go Test while counting backwards by three; (iii) manual dual-task: Timed Up & Go Test while carrying a glass of water. A repeated measures anova with between-factor as age groups and within-factor as tasks was carried out to assess the effect of aging on the performance of mobility tasks. DTC was calculated as ([performance in single-task - performance in dual-task] / performance in single task) × 100%. One-way ancova were carried out to compare the DTC among the three age groups. A significant interaction between age groups and task (F 4,172  = 6.716, P < 0.001, partial η 2  = 0.135) was observed. Specifically, older women showed a worse mobility performance under dual-task condition compared with young and middle-aged groups. Furthermore, DTC differences in cognitive task were observed in older women compared with younger and middle-aged women (F 2,86  = 7.649, P < 0.001, partial η 2  = 0.151), but not in manual task. Dual-task conditions might affect mobility performance differently across the lifespan, and could be particularly challenging in older women.

In 1980 and 1981 Mennonite descendants of a group of Russian immigrants participated in a multidisciplinary study of biological aging. The Mennonites live in Goessel, Kansas, and Henderson, Nebraska. In 1991 the survival status of the participants was documented by each church secretary. Data are available for 1009 individuals, 177 of whom are now deceased. They ranged from 20 to 95 years in age when the data were collected. Biological ages were computed using a stepwise multiple regression procedure based on 38 variables previously identified as being related to survival, with chronological age as the dependent variable. Standardized residuals place participants in either a predicted-younger or a predicted-older group. The independence of the variables biological age and survival status is tested with the chi-square statistic. The significance of biological age differences between surviving and deceased Mennonites is determined by t test values. The two statistics provide consistent results. Predicted age group classification and survival status are related. The group of deceased participants is generally predicted to be older than the group of surviving participants, although neither statistic is significant for all subgroups of Mennonites. In most cases, however, individuals in the predicted-older groups are at a relatively higher risk of dying compared with those in the predicted-younger groups, although the increased risk is not always significant.

Education of health science students in geriatrics is important in order to provide optimal care for the growing number of elderly people because it is the attitudes of health professionals toward the elderly that play the key role in the quality of care provided. Therefore, the aim of this study was to assess the knowledge and attitudes of health care science students towards ageing and care for the elderly. The present cross-sectional study was carried out on a sample of 130 students (medical, nursing and special education and rehabilitation) of the Faculty of Medicine, University of Novi Sad. The students were divided into two groups. The first group (E) included students having been taught geriatrics and nursing older adults and the other group (C) included students who had not been trained in this subject. The authors used Palmore's facts on Ageing Quiz for the knowledge evaluation and Kogan's Attitude toward Older People Scale for the attitude evaluation. The results of Facts on Aging Quiz showed the average level of students' knowledge and statistically significant difference between E and C group. The analysis of Kogan's Attitudes toward Old People Scale showed that both groups had neutral attitudes toward older people. Furthermore, a positive correlation between students' knowledge and attitudes was found. There is increasing evidence on the correlation between education, knowledge and attitudes toward older people which suggests that by acquiring better insights into all aspects of ageing through their education the students develop more positive attitudes and interest in working with older adults.

To examine the effect of regular ongoing exercise lifestyle on mental and physical health in a group of independent community-dwelling Taiwanese older adults over a 2-year period. 197 older adults (mean age 72.5 years; 106 men and 91 women) who were independent in walking, instrumental and basic activities of daily living completed the baseline and a 2-year follow-up assessment. Older adults regularly performing exercises during the 2-year study period were grouped into regular exercise group; otherwise in the irregular exercise group. Baseline and follow-up assessments included a face-to-face interview and a battery of performance tests. The regular exercise group showed significantly less depression (P = 0.03) and tended to regress less on the performance tests (P = 0.025-0.410) across 2 years compared to the irregular exercise group. Regular exercise is important for maintaining or even improving mental and functional health, even for independent community-dwelling older adults. © 2010 The Authors.

Characteristics of older frequent users of Emergency Departments (EDs) are poorly understood. Our aim was to examine the characteristics of the ED frequent attenders (FAs) by age (under 65 and over 65 years). We examined the prevalence of FA attending the ED of an Urban Teaching Hospital in a cross-sectional study between 2009 and 2011. FA was defined as an individual who presented to the ED four or more times over a 12-month period. Randomly selected groups of FA and non-FA from two age groups (under 65 and over 65 years) were then examined to compare the characteristics between older FAs and non-FAs and older FAs and younger FAs. Logistic regression was used to calculate the odds ratio and 95% confidence intervals for 12-month mortality in FA compared with non-FA aged at least 65 years. Overall, 137 150 ED attendances were recorded between 2009 and 2011. A total of 21.6% were aged at least 65 years, 4.4% of whom were FAs, accounting for 18.4% of attendances by patients older than 65 years. There was a bimodal age distribution of FA (mean±SD; under 65 years 40±12.7; and over 65 years 76.9±7.4). Older FAs were five times more likely to present outside normal working hours and 5.5 times more likely to require admission. Cardiovascular emergencies were the most common complaint, in contrast with the younger FA group, where injury and psychosocial conditions dominated. The odds ratio for death at 12 months was 2.07 (95% confidence interval 0.93-4.63; P=0.07), adjusting for age and sex. One-in-five ED patients older than 65 years of age are FAs. Older FAs largely present with complex medical conditions. Enhanced access to expert gerontology assessment should be considered as part of effective intervention strategies for older ED users.

The objective of the present study was to verify how socioeconomic and physical/mental health status would be associated with activity limitations by age and sex among older adults, using nationally representative cross-sectional data in Japan. The present study focused on 8373 older adults aged 65 years or older extracted from the Comprehensive Survey of Living Conditions conducted in 2007 by the Japanese Ministry of Health, Labor and Welfare. Univariate and multiple logistic regression analyses and population-attributable risk were applied to validate the relationships of socioeconomic and physical/mental health status with activity limitations among the total population, and by age groups (young-old or old-old) and sex. Mental health showed the highest odds ratio and population-attributable risk in the total population. In addition, low back pain was associated with activity limitations regardless of age and sex. Other musculoskeletal diseases, such as arthropathy and osteoporosis, were related to activity limitations for women, regardless of age, whereas cardiovascular diseases, including angina pectoris/myocardial infarction and cerebral stroke, were associated with activity limitations for men in any age group. There were no statistically significant correlations between socioeconomic status and activity limitations in any groups. Mental health was the most important factor of activity limitations in Japanese older adults. Furthermore, low back pain regardless of age and sex, other musculoskeletal diseases only for women and cardiovascular diseases mainly for men could also be significant risk factors to activity limitations. Therefore, preventive approaches of activity limitations considering sex differences are important for older adults in Japan. Geriatr Gerontol Int 2015; ●●: ●●-●●. © 2015 Japan Geriatrics Society.

Assessment of unconstrained cerebrovascular reactivity marker for large age-range FMRI studies.

Breath hold (BH), a commonly used task to measure cerebrovascular reactivity (CVR) in fMRI studies varies in outcome among individuals due to subject-physiology and/or BH-inspiration/expiration differences (i.e., performance). In prior age-related fMRI studies, smaller task-related BOLD response variability is observed among younger than older individuals. Also, a linear CVR versus task relationship exists in younger individuals which maybe useful to test the accuracy of CVR responses in older groups. Hence we hypothesized that subject-related physiological and/or BH differences, if present, may compromise CVR versus task linearity in older individuals. To test the hypothesis, empirical BH versus task relationships from motor and cognitive areas were obtained in younger (mean age = 26 years) and older (mean age = 58 years) human subjects. BH versus task linearity was observed only in the younger group, confirming our hypothesis. Further analysis indicated BH responses and its variability to be similar in both younger and older groups, suggesting that BH may not accurately represent CVR in a large age range. Using the resting state fluctuation of amplitude (RSFA) as an unconstrained alternative to BH, subject-wise correspondence between BH and RSFA was tested. Correlation between BH versus RSFA was significant within the motor but was not significant in the cognitive areas in the younger and was completely disrupted in both areas in the older subjects indicating that BH responses are constrained by subject-related physiology and/or performance-related differences. Contrasting BH to task, RSFA-task relationships were independent of age accompanied by age-related increases in CVR variability as measured by RSFA, not observed with BH. Together the results obtained indicate that RSFA accurately represents CVR in any age range avoiding multiple and yet unknown physiologic and task-related pitfalls of BH.

Task Inhibition and Response Inhibition in Older vs. Younger Adults: A Diffusion Model Analysis

2016-01-01

Differences in inhibitory ability between older (64–79 years, N = 24) and younger adults (18–26 years, N = 24) were investigated using a diffusion model analysis. Participants performed a task-switching paradigm that allows assessing n−2 task repetition costs, reflecting inhibitory control on the level of tasks, as well as n−1 response-repetition costs, reflecting inhibitory control on the level of responses. N−2 task repetition costs were of similar size in both age groups. Diffusion model analysis revealed that for both younger and older adults, drift rate parameters were smaller in the inhibition condition relative to the control condition, consistent with the idea that persisting task inhibition slows down response selection. Moreover, there was preliminary evidence for task inhibition effects in threshold separation and non-decision time in the older, but not the younger adults, suggesting that older adults might apply different strategies when dealing with persisting task inhibition. N−1 response-repetition costs in mean RT were larger in older than younger adults, but in mean error rates tended to be larger in younger than older adults. Diffusion-model analysis revealed longer non-decision times in response repetitions than response switches in both age groups, consistent with the idea that motor processes take longer in response repetitions than response switches due to persisting response inhibition of a previously executed response. The data also revealed age-related differences in overall performance: Older adults responded more slowly and more accurately than young adults, which was reflected by a higher threshold separation parameter in diffusion model analysis. Moreover, older adults showed larger non-decision times and higher variability in non-decision time than young adults, possibly reflecting slower and more variable motor processes. In contrast, overall drift rate did not differ between older and younger adults. Taken together, diffusion model analysis revealed differences in overall performance between the age groups, as well as preliminary evidence for age differences in dealing with task inhibition, but no evidence for an inhibitory deficit in older age.

Recurrent shoulder dislocation is infrequent after forty years and presents different injuries than younger patients. To compare injuries and complications after surgery between one group older than forty years of age and another younger group. A review was made o all patients who had undergone arthroscopic surgery due to glenohumeral instability from 1999 until 2011. The mean follow-up was 64 months. The case group consisted of all patients older than 40 years at the time of the surgery (n=21), which was compared with a similar sized control group of randomly selected younger patients (n=27). The mean age in the older group was 54 years (SD 11.86), while it was 26 years (SD 5.80) in the younger group. No differences were founded between both groups in labrum injury, Hill-Sachs injury, and bone Bankart lesion (P>.05). Rotator cuff tears were 7.3 times (95% CI; 2.5-21.6) more frequent in the older group (81%) compared to the younger group (P<.05). However, neurological injuries after dislocation were not more frequent in this group. There was no significant difference between the complications after surgery and the age according to the design (P>.05). Anterior recurrent dislocation after forty years of age is usually associated with rotator cuff tears. Arthroscopic treatment of instability was effective with no more postoperative complications.

The study examined the relationships between social contact types and psychological distress among mid-older adults. Self-completed data from 236,490 Australian adults aged 45+ years. There was a consistent relationship between increased frequency in phone contacts, social visits, and social group contacts and reduced risk of psychological distress adjusted for demographic and health factors. However, stratified analyses by age showed, with one exception, that no significant associations were found between social group contact frequency and risk of psychological distress for those aged 85 years and older. Furthermore, significant interaction terms revealed that women experience a steeper reduction in risk than men at age 65 to 74 years and 75 to 84 years compared with those aged 45 to 64 years. Social contacts have age and gender differential effects on psychological distress of mid-older Australian adults. Interventions addressing social interaction need to be sensitive to gender and age differences.

Transcranial direct current stimulation (tDCS) may be a viable tool to improve motor and cognitive function in advanced age. However, although a number of studies have demonstrated improved cognitive performance in older adults, other studies have failed to show restorative effects. The neural effects of beneficial stimulation response in both age groups is lacking. In the current study, tDCS was administered during simultaneous fMRI in 42 healthy young and older participants. Semantic word generation and motor speech baseline tasks were used to investigate behavioral and neural effects of uni- and bihemispheric motor cortex tDCS in a three-way, crossover, sham tDCS controlled design. Independent components analysis assessed differences in task-related activity between the two age groups and tDCS effects at the network level. We also explored whether laterality of language network organization was effected by tDCS. Behaviorally, both active tDCS conditions significantly improved semantic word retrieval performance in young and older adults and were comparable between groups and stimulation conditions. Network-level tDCS effects were identified in the ventral and dorsal anterior cingulate networks in the combined sample during semantic fluency and motor speech tasks. In addition, a shift toward enhanced left laterality was identified in the older adults for both active stimulation conditions. Thus, tDCS results in common network-level modulations and behavioral improvements for both age groups, with an additional effect of increasing left laterality in older adults.

The number of people in the United States aged 65 years and older is increasing. Older people have a higher risk of dying from cancer; however, recent information about breast and colorectal cancer screening rates among women aged 65 years and older and about sources of health information consulted by these women is limited. We examined data from the Health Information National Trends Survey for women aged 65 years and older who had no personal history of breast or colorectal cancer. Women whose self-reported race and ethnicity was non-Hispanic white, non-Hispanic black, or Hispanic were included in the analysis. The overall response rate for the 2003 survey was 34.5%. Women aged 75 years and older had lower rates of recent mammography (mammogram in previous 2 years) than did women aged 65 to 74 years. In both age groups, rates were especially low for Hispanic women and women with a household income of less than $15,000 per year. Rates of recent colorectal cancer screening (fecal occult blood test in previous year or endoscopy in previous 5 years) were markedly lower for non-Hispanic black women aged 75 years and older than for other women in this age group, and for Hispanic women aged 65 to 74 years than for non-Hispanic women in this age group. Screening rates were lowest for women with an annual household income of less than $15,000, no family history of cancer, no usual health care provider, or 1 or no provider visits in the previous year. Differences were found in the groups' preferred channel for receiving health information. Women who had had a mammogram in the previous 2 years were more likely to pay attention to health information on the radio or in newspapers and magazines than were women who had not received a recent mammogram. Women who had had a recent colorectal cancer screening test were more likely to pay attention to health information in magazines or on the Internet than were those who had not. Personalized print and other publications were the most preferred channel for receiving health information. The results from this analysis suggest that educational materials about routine breast and colorectal cancer screening appropriate for women aged 65 years and older (especially low-income women, Hispanic women, and those aged 65 to 74 years) may be helpful.

Background: Accumulating evidence indicates that cognitive remediation (CR) is effective for improving various cognitive deficits in adult patients with schizophrenia. Although reports of brain plasticity in older adults and the service needs for chronic patients with schizophrenia are increasing, very few randomized controlled trials of CR have been conducted in middle-aged or older inpatients with chronic schizophrenia. We investigated the efficacy of individualized CR on the cognitive impairments of middle-aged or older inpatients with chronic schizophrenia within the context of comprehensive psychiatric rehabilitation (PR) by comparing the results obtained with PR only and treatment as usual (TAU). Method: Fifty-seven middle-aged and older individuals with chronic schizophrenia and mild to moderate cognitive deficits were enrolled. Thirty-eight who were undergoing PR were randomly assigned to CR + PR ( N = 19) or PR-only ( N = 19) groups. Nineteen participants who were undergoing TAU without CR or PR were evaluated pre- and post-treatment. Results: CR was easily provided and well received (drop-out rates = 5.3%) by middle-aged or older psychiatric inpatients. Compared to the PR-Only or TAU patients, patients in the CR + PR group showed greater improvement in executive functioning. Compared to TAU patients, CR + PR and PR-only patients showed greater improvement in logical memory. More patients in the CR + PR group improved clinically significantly in executive functioning and logical memory, compared with the PR-only and TAU patients. Conclusions: These results suggested that CR improved some cognitive deficits in middle-aged or older inpatients with chronic schizophrenia and that it was effective as an adjunctive treatment to the usual PR services provided in inpatient settings.

Attention HIV: older African American women define sexual risk.

McCord, Laneshia R

2014-01-01

Understanding sexual-risk behaviours as defined by a culture presents new challenges for human service professionals. Older African American women constitute the fastest growing group of new cases of HIV in the USA. With heterosexual sex as the primary mode of transmission among this group, there exist minimal programmes that are culture and age-specific in terms of primary and secondary prevention. In an attempt to address this gap in knowledge, this study examined how a group of older African American women defined sexual-risk behaviour. A focus group was conducted with seven women age 45 and older, who were recruited from a community centre. This paper examines the way that sexual-risk behaviour was defined through thematic analysis and conceptualises the locus of sexual risk behaviour as defined by the participants. The major theme of the study was social prescription, how to behave sexually as an ageing adult. Underlying ideas that arose were that unprotected sex occurred out of habit, that impulsivity was associated with risky sex and that older women needed to be aware of warning signs and behaviours of potential mates. Micro- and macro-level implications for human service professionals are discussed.

Tranexamic acid effects in older people are difficult to predict. This study investigated the following research questions: 1) Is tranexamic acid effective in older patients undergoing primary total hip arthroplasty (THA)? and 2) Is there a difference in the effect of tranexamic acid between younger and older patients? This was a 2-phase retrospective matched-pair study of patients who underwent THA in 2007-2013. All procedures were performed by surgeons with at least 10 years' experience as senior consultant. In the first phase, 58 patients aged 65 years or more who received tranexamic acid were matched 1:1 with patients who did not receive tranexamic acid for age, sex, American Society of Anesthesiologists (ASA) classification and body mass index. In the second phase, 58 patients aged 65 years or more who received tranexamic acid were matched 1:1 with patients less than 65 years of age who received tranexamic acid for sex, ASA classification and body mass index. The primary outcome measures were percent maximum decrease in hemoglobin level and estimated blood loss after surgery. In the first phase, patients who received tranexamic acid conserved postoperative hemoglobin by a mean of 10.26 g/L (standard deviation [SD] 9.89 g/L) compared to the control group ( p < 0.001). The mean difference in the estimated perioperative blood loss between the 2 groups was 410 mL (SD 376 mL) ( p < 0.001), which indicated less bleeding in the treatment group. In the second phase, there was no difference between the younger (mean age 55.1 [SD 7.28] yr) and older (mean age 75.6 [SD 6.35] yr) groups in mean lowest postoperative hemoglobin level or percent decrease in hemoglobin level. Tranexamic acid reduced the postoperative decrease in hemoglobin level and blood loss in older patients. Moreover, the significant hemoglobin-sparing effect of tranexamic acid in older patients was similar to that observed in younger patients.

Aging increases the risk of developing impaired glucose tolerance (IGT) and type 2 diabetes. It has been proposed that increased reactive oxygen species (ROS) generation by dysfunctional mitochondria could play a role in the pathogenesis of these metabolic abnormalities. We examined whether aging per se (in subjects with normal glucose tolerance [NGT]) impairs mitochondrial function and how this relates to ROS generation, whether older subjects with IGT have a further worsening of mitochondrial function (lower ATP production and elevated ROS generation), and whether exercise reverses age-related changes in mitochondrial function. Mitochondrial ATP and ROS production were measured in muscle from younger individuals with NGT, older individuals with NGT, and older individuals with IGT. Measurements were performed before and after 16 weeks of aerobic exercise. ATP synthesis was lower in older subjects with NGT and older subjects with IGT versus younger subjects. Notably, mitochondria from older subjects (with NGT and IGT) displayed reduced ROS production versus the younger group. ATP and ROS production were similar between older groups. Exercise increased ATP synthesis in the three groups. Mitochondrial ROS production also increased after training. Proteomic analysis revealed downregulation of several electron transport chain proteins with aging, and this was reversed by exercise. Old mitochondria from subjects with NGT and IGT display mitochondrial dysfunction as manifested by reduced ATP production but not with respect to increased ROS production. When adjusted to age, the development of IGT in elderly individuals does not involve changes in mitochondrial ATP and ROS production. Lastly, exercise reverses the mitochondrial phenotype (proteome and function) of old mitochondria.

Many elderly people complain of disturbed sleep patterns but there is not evidence that the need to sleep decreases with age; it seems rather that the timing and consolidation of sleep change. We tried to find out whether there is a concurrent change in the output of the circadian pacemaker with age. The phase and amplitude of the pacemaker's output were assessed by continuous measurement of the core body temperature during 40 h of sustained wakefulness under constant behavioural and environmental conditions. 27 young men (18-31 years) were compared with 21 older people (65-85 years; 11 men, 10 women); all were healthy and without sleep complaints. The mean amplitude of the endogenous circadian temperature oscillation (ECA) was 40% greater in young men than in the older group. Older men had a lower mean temperature ECA than older women. The minimum of the endogenous phase of the circadian temperature oscillation (ECP) occurred 1 h 52 min earlier in the older than in the young group. Customary bedtimes and waketimes were also earlier in the older group, as was their daily alertness peak. There was a close correlation between habitual waketime and temperature ECP in young men, which may lose precision with age, especially among women. These findings provide evidence for systematic age-related changes in the output of the human circadian pacemaker. We suggest that these changes may underlie the common complaints of sleep disturbance among elderly people. These changes could reflect the observed age-related deterioration of the hypothalamic nuclei that drive mammalian circadian rhythms.

The purpose of this study was to examine the effect of participation in a music-based intergenerational music program on cross-age interactions and cross-age attitudes of elementary-age children and older adults, and older adults' psychosocial well-being. Twenty-one children in the 4th grade volunteered to participate in the experimental (n = 12) or control (n = 9) group. Twenty-six older adults from a retirement living facility also volunteered to participate in the experimental (n = 14) or control (n = 12) group. Ten 30-min music sessions occurred in which participants engaged in singing, structured conversation, moving to music, and instrument playing interventions. Data analysis of cross-age interactions revealed that the interventions "structured conversation" and "moving to music" were more effective in eliciting interaction behaviors than the interventions "singing" and "instrument playing." Standardized measures revealed that children's attitudes towards older adults improved, though not significantly so, after participation in the intergenerational program. Results of biweekly post-session questionnaires revealed a decrease in negative descriptions of older adults and an increase in positive descriptions of older adults--suggesting a more positive view towards aging. Results revealed that older adults' attitudes towards children improved significantly after their participation in the intergenerational program. While standardized measures revealed that older adults did not perceive a significant improvement in their psychosocial well-being, their bi-weekly post-session questionnaires showed they perceived increased feelings of usefulness and other personal benefits from the intergenerational interactions. Suggestions for future research, the utility of varied measurement instruments, and implications for practice are discussed.

Validity of self-reported height, weight, and body mass index: findings from the National Health and Nutrition Examination Survey, 2001-2006.

Our study extends previous studies that have evaluated the level of bias in self-reported height and weight and corresponding body mass index (BMI). Results are evaluated by age, sex, income, race/ethnicity, and BMI classifications. Analyses are based on the National Health and Nutrition Examination Survey (NHANES) from 2001-2006. The sample was 8,208 men and 8,606 women aged 16 years or older. On average, men overreport their height by 1.22 cm (0.48 in) and their weight by 0.30 kg (0.66 lbs), and women overreport their height by 0.68 cm (0.27 in) and underreport their weight by -1.39 kg (-3.06 lbs). Overreporting of height significantly increases with age after age 50 for men and after age 60 for women. Overreporting of weight in men is significant in the age groups 16 to 49 years and 70 years or older. Women significantly underreport their weight in each age group but more so in the age group 16 to 49 years, followed by 50 to 69 years, and then 70 years or older. Men are more likely than women to think their weight is about right if they are at a normal weight or are overweight or obese, but women are more likely to think their weight is about right if they are underweight. Men and women significantly overreport their height, increasingly so at older ages. Men tend to overestimate their weight, but women underreport their weight, more so in younger ages. Corresponding BMI is underestimated, more so for women than for men at each age and increasingly so with older age for both sexes.

We tested the hypothesis that aging is associated with prolonged leg vasodilator kinetics and habitual exercise training in older adults improves these responses relative to untrained older adults. Additionally, we examined the relationship between contraction-induced rapid onset vasodilation (ROV) and vasodilator kinetics. Young (n=10), older untrained (n=13) and older trained (n=14) adults performed single and rhythmic knee-extension contractions at 20% and 40% work-rate maximum (WR max ). Femoral artery diameter and mean blood velocity were measured by Doppler ultrasound. Vascular conductance (VC; ml·min -1 ·mmHg-1) was calculated using blood flow (ml·min -1 ) and mean arterial pressure (mmHg). The primary outcome was the kinetic response (mean response time; MRT), modeled using an exponential model, expressed as the number of duty cycles to change 63% of the steady-state amplitude. There was no age or training related differences in VC MRT between the groups at 20% WR max . Older untrained adults exhibited prolonged VC MRT at 40% WR max relative to young (37{plus minus}16 vs. 24{plus minus}10 duty-cycles; P<0.05) and older trained adults (37{plus minus}16 vs. 23{plus minus}14 duty-cycles; P<0.05). There were no differences in VC MRT between young and older trained adults at 40% WR max (P=0.96). There were no associations between peak ROV and VC MRT at 20% or 40% WR max (r=-0.08 and 0.22; P=0.67 and 0.20, respectively) in the group as a whole. Our data suggest 1) advancing age prolongs leg vasodilator kinetics; 2) habitual exercise training in older adults offsets this age-related prolongation; and 3) contraction-induced ROV is not related to vasodilator kinetics within a group of young and older adults.

Age-related differences in strategy knowledge updating: blocked testing produces greater improvements in metacognitive accuracy for younger than older adults.

Price, Jodi; Hertzog, Christopher; Dunlosky, John

2008-09-01

Age-related differences in updating knowledge about strategy effectiveness after task experience have not been consistently found, perhaps because the magnitude of observed knowledge updating has been rather meager for both age groups. We examined whether creating homogeneous blocks of recall tests based on two strategies used at encoding (imagery and repetition) would enhance people's learning about strategy effects on recall. Younger and older adults demonstrated greater knowledge updating (as measured by questionnaire ratings of strategy effectiveness and by global judgments of performance) with blocked (versus random) testing. The benefit of blocked testing for absolute accuracy of global predictions was smaller for older than younger adults. However, individual differences in correlations of strategy effectiveness ratings and postdictions showed similar upgrades for both age groups. Older adults learn about imagery's superior effectiveness but do not accurately estimate the magnitude of its benefit, even after blocked testing.

Incidence of C-2 fracture is increasing in elderly patients. Patient age also influences decision making in the management of these fractures. There are very limited data on the national trends of incidence, treatment interventions, and resource utilization in patients in different age groups with isolated C-2 fractures. The aim of this study is to investigate the incidence, treatment, complications, length of stay, and hospital charges of isolated C-2 fracture in patients in 3 different age groups by using the Nationwide Inpatient Sample (NIS) database. The data were obtained from NIS from 2002 to 2011. Data on patients with closed fractures of C-2 without spinal cord injury were extracted using ICD-9-CM diagnosis code 805.02. Patients with isolated C-2 fractures were identified by excluding patients with other associated injuries. The cohort was divided into 3 age groups: < 65 years, 65-80 years, and > 80 years. Incidence, treatment characteristics, inpatient/postoperative complications, and hospital charges (mean and total annual charges) were compared between the 3 age groups. A total of 10,336 patients with isolated C-2 fractures were identified. The majority of the patients were in the very elderly age group (> 80 years; 42.3%) followed by 29.7% in the 65- to 80-year age group and 28% in < 65-year age group. From 2002 to 2011, the incidence of hospitalization significantly increased in the 65- to 80-year and > 80-year age groups (p < 0.001). However, the incidence did not change substantially in the < 65-year age group (p = 0.287). Overall, 21% of the patients were treated surgically, and 12.2% of the patients underwent nonoperative interventions (halo and spinal traction). The rate of nonoperative interventions significantly decreased over time in all age groups (p < 0.001). Regardless of treatment given, patients in older age groups had a greater risk of inpatient/postoperative complications, nonroutine discharges, and longer hospitalization. The mean hospital charges were significantly higher in older age groups (p < 0.001). The incidence of hospitalization for isolated C-2 fractures is progressively increasing in older age groups. Simultaneously, there has been a steadily decreasing trend in the preference for nonoperative interventions. Due to more complicated hospital stay, longer hospitalizations, and higher rates of nonroutine discharges, the patients in older age groups seem to have a higher propensity for greater health care resource utilization.

Pain is common in the aging population, particularly among older residents of nursing homes. It has been found that 50% of older people living in the community have been experiencing chronic pain, and the number increased to 80% for older residents of nursing homes. Exercise is an effective non-pharmacological intervention that can reduce pain and improve physical and psychological functions. A quasi-experimental study with a pretest-posttest control group designed was conducted to evaluate the effects of a physical exercise program (PEP) on older residents of nursing homes who have chronic pain. Three-hundred-ninety-six older residents with chronic pain were recruited from 10 nursing homes run by non-governmental organizations in Hong Kong. The average age of the older residents was 85.44 ± 6.29. Five nursing homes were randomized to the experimental group with PEP (n = 225, age = 85.45 ± 6.25); the other five nursing homes were randomized to the control group without the PEP (n = 171, age = 85.44 ± 6.35). PEP was an eight-week training program given by a physiotherapist and nurses once a week. It consisted of warm-up exercises, muscle strengthening, stretching, balancing, and self-administered massage to acupressure points. At the end of each PEP session, pamphlets with pictures illustrating the "exercise of the day" were given to the older residents of nursing homes as a tool to enhance their self-management skills. The control group received no training during the eight weeks. Upon completion of the PEP, the experimental group experienced a significantly greater reduction in pain intensity from 4.19 ± 2.25 (on an 11 point scale) to 2.67 ± 2.08, as compared to the control group (p < .05). In addition, the psychological well-being (happiness, loneliness, life satisfaction, and depression) of the experimental group was significantly improved (p < .05).

It has been observed that subjective age (SA) often trails chronological age, especially in older adults. In a previously published article, we argued that differences in individual's SA is a function of their level of activity on biological, mental, and social dimensions. This article empirically tests this proposition using a newly created Subjective Aging Index (SAI). The SAI is related to SA above the effect of age with differences existing across age groups and sex. The findings contribute to the literature on successful aging strategies with important implications for health care practitioners, marketers, and individuals heading towards older adult years.

In previous phase 1-2 clinical trials involving older adults, a subunit vaccine containing varicella-zoster virus glycoprotein E and the AS01B adjuvant system (called HZ/su) had a clinically acceptable safety profile and elicited a robust immune response. We conducted a randomized, placebo-controlled, phase 3 study in 18 countries to evaluate the efficacy and safety of HZ/su in older adults (≥50 years of age), stratified according to age group (50 to 59, 60 to 69, and ≥70 years). Participants received two intramuscular doses of the vaccine or placebo 2 months apart. The primary objective was to assess the efficacy of the vaccine, as compared with placebo, in reducing the risk of herpes zoster in older adults. A total of 15,411 participants who could be evaluated received either the vaccine (7698 participants) or placebo (7713 participants). During a mean follow-up of 3.2 years, herpes zoster was confirmed in 6 participants in the vaccine group and in 210 participants in the placebo group (incidence rate, 0.3 vs. 9.1 per 1000 person-years) in the modified vaccinated cohort. Overall vaccine efficacy against herpes zoster was 97.2% (95% confidence interval [CI], 93.7 to 99.0; P<0.001). Vaccine efficacy was between 96.6% and 97.9% for all age groups. Solicited reports of injection-site and systemic reactions within 7 days after vaccination were more frequent in the vaccine group. There were solicited or unsolicited reports of grade 3 symptoms in 17.0% of vaccine recipients and 3.2% of placebo recipients. The proportions of participants who had serious adverse events or potential immune-mediated diseases or who died were similar in the two groups. The HZ/su vaccine significantly reduced the risk of herpes zoster in adults who were 50 years of age or older. Vaccine efficacy in adults who were 70 years of age or older was similar to that in the other two age groups. (Funded by GlaxoSmithKline Biologicals; ZOE-50 ClinicalTrials.gov number, NCT01165177.).

We report a longitudinal comprehension study of (long) passive constructions in two native-Spanish child groups differing by age of initial exposure to L2 English (young group: 3;0-4;0; older group: 6;0-7;0), where amount of input, L2 exposure environment, and socioeconomic status are controlled. Data from a forced-choice task show that both…

[How educating students in depression among older people can affect their motivation to work with this population].

Negative representations of ageing are conveyed in our society. We see that people frequently avoid working with older people, due to a lack of motivation. Depressive signs in older people are more frequently associated with normal ageing, rather than a pathology, giving health professionals the feeling that therapeutic efforts are likely to be unproductive. Yet, depression is a major public health problem, particularly among older people. It is a real pathology, affecting 20% of people aged 65 and older. In retirement homes the percentage can be as high as 45%. To study and evaluate how theoretical knowledge about older people and depression affects the motivation of 2nd year psychology students to work with this population. The study involves two groups. One of the groups (experimental group) followed an 8hour course on depression in older people, whereas the other (control group) followed an 8hour course on a different topic. The study was conducted in two parts. First, the two groups answered an initial questionnaire which measured how motivated they were to work with older people and what they knew about depression in older people. Then, after the experimental phase, all of the students answered the same questionnaire a second time. The comparison shows a significant decline in knowledge between T1 and T2 for the control group (P<0.05), and a significant increase in the number of correct answers for the experimental group (P<0.001). Statistical results show that after receiving education in depression, students are more motivated to work with older people. Moreover, we observe that the more knowledge students have in this field, the more motivated they will be to work with older people. Whereas there were no differences in knowledge before the course, we observed that the knowledge of the group who took part in the course about older people improved. Also, the evaluation showed that students who took the course were significantly more knowledgeable. Regarding motivation, our results vary according to the type of motivation. Overall, as regards intrinsic motivation, we observed an increase in motivation, insofar as the students who had followed the course were subsequently more likely to work with older people. Taking part in the course led to a systematic increase in the evaluation of extrinsic motivation. With respect to knowledge, half of the students interviewed think sadness or depression is a natural part of ageing. So, we observe that future health professionals often regard the signs observed in this population, such as sadness, apathy, and depression, as part of normal ageing. The people working with older people do not make the connection to actions and consequently in this action to wrongly thinking they are not in control of the situation. Depression is widely underestimated. Forty percent of cases of depression among older people go undetected. This study highlights the importance of making health professionals and future health professionals more aware of depression among older people. Knowing more about depression in this population can help guide recourse to psychology in gerontology. Copyright © 2016 L’Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.

Context Although numerous risk factors have been established to predict the development of acute coronary syndrome (ACS), the risk factor profile may be different between the younger and older individuals. Aim To analyse the frequency and pattern of atherogenic risk factors and angiographic profiles in age-stratified Gujarati patients with ACS. Materials and Methods ACS patients undergoing coronary angiography at U.N. Mehta Institute of Cardiology and Research, Gujarat, India between January 2008 and December 2012 were classified in to two age groups with 40y as cut-off. Patients were assessed for conventional risk factors (diabetes mellitus, dyslipidaemia, hypertension, smoking, obesity), novel risk factors (high sensitivity C-reactive protein, lipoprotein (a), homocysteine), and angiographic profiles.The statistical difference between two age groups was determined by Student’s t-test for continuous variables and Chi-square or Fisher’s exact test for categorical variables. Results A total of 200 patients, 100 patients ≤40 y of age and 100 patients >40 y of age, were evaluated. Older patients had higher frequency of hypertension (32 vs. 16%, p=0.008), while family history of coronary artery disease was more common among younger patients (19 vs. 9%, p=0.041). The incidence of diabetes, dyslipidaemia, smoking and tobacco chewing did not vary significantly between the two groups. Total cholesterol and low-density lipoprotein cholesterol levels were significantly higher in the younger group (p<0.05). Lipoprotein (a), homocysteine and high-sensitivity C reactive protein levels were comparable between two age groups. Multi-vessel coronary artery disease was more common among older group. The most commonly affected coronary artery was the left anterior descending artery among younger patients (44%) and the left circumflex artery among older patients (38.1%). Conclusion Young patients with ACS had different atherosclerotic risk profile and less extensive coronary artery disease as compared to older counterparts. Emphasis should be given on diagnosis and management of major modifiable risk factors. PMID:26266146

Older voters and the 2010 U.S. election: implications for 2012 and beyond?

To analyze the extent to which Americans aged 65 and older may have voted as an old age-benefits bloc in the 2010 midterm election in response to threats of Medicare rationing. Analysis of age group data from the Edison Research 2010 Election Day exit polls, complemented by data published elsewhere. For the first time in 4 decades, there were signs of an old-age voting bloc in the 2010 election; yet, analysis of the age group data by sex and race/ethnicity reveals notable differences among these subgroups. This new tendency toward old-age bloc voting may well continue in the 2012 election and beyond. If "reforming" Medicare and Social Security persist as policy issues, the votes of older persons may increasingly be affected to a much greater degree than in past elections.

Co-morbid anxiety and depression in older adults is associated with worse physical and mental health outcomes and poorer response to psychological and pharmacological treatments in older adults. However, there is a paucity of research focused on testing the efficacy of the co-morbid treatment of anxiety and depression in older adults using psychological interventions. Accordingly, the primary objective of the current study was to test the effects of a group cognitive behavior therapy (CBT) program in treating co-morbid anxiety and depression in a sample of older age adults. A total of 133 community-dwelling participants aged ⩾60 years (mean age = 67.35, s.d. = 5.44, male = 59) with both an anxiety disorder and unipolar mood disorder, as assessed on the Anxiety Disorder Interview Schedule (ADIS), were randomly allocated to an 11-week CBT group or discussion group. Participants with Mini-Mental State Examination scores <26 were excluded. Participants were assessed pre-treatment, post-treatment and at 6 months follow-up on the ADIS, a brief measure of well-being, Geriatric Anxiety Inventory and Geriatric Depression Scale. Both conditions resulted in significant improvements over time on all diagnostic, symptom and wellbeing measures. Significant group × time interaction effects emerged at post-treatment only for diagnostic severity of the primary disorder, mean severity of all anxiety disorders, mood disorders, and all disorders, and recovery rates on primary disorder. Group CBT produced faster and sustained improvements in anxiety and depression on diagnostic severity and recovery rates compared to an active control in older adults.

To evaluate time trends in surgical resection rates and operative mortality in older adults diagnosed with locoregional pancreatic cancer and to determine the effect of age on surgical resection rates and 2-year survival after surgical resection. Retrospective cohort study using data from the Surveillance, Epidemiology, and End Results (SEER) and linked Medicare claims database (1992-2005). Secondary data analysis of population-based tumor registry and linked claims data. Medicare beneficiaries aged 66 and older diagnosed with locoregional pancreatic cancer (N=9,553), followed from date of diagnosis to time of death or censorship. Percentage of participants undergoing surgical resection, 30-day operative mortality after resection, and 2-year survival according to age group. Surgical resection rates increased significantly, from 20% in 1992 to 29% in 2005, whereas 30-day operative mortality rates decreased from 9% to 5%. After controlling for multiple factors, participants were less likely to be resected with older age. Resection was associated with lower hazard of death, regardless of age, with hazard ratios of 0.46, 0.51, 0.47, 0.43, and 0.35 for resected participants younger than 70, 70 to 74, 75 to 79, 80 to 84, and 85 and older respectively compared with unresected participants younger than 70 (P<.001). With older age, fewer people with pancreatic cancer undergo surgical resection, even after controlling for comorbidity and other factors. This study demonstrated increased resection rates over time in all age groups, along with lower surgical mortality rates. Despite previous reports of greater morbidity and mortality after pancreatic resection in older adults, the benefit of resection does not diminish with older age in selected people. © 2011, Copyright the Authors.

Sebastián, Manuel; Reales, José M; Ballesteros, Soledad

2011-12-01

In this electrophysiological study, we investigated the effects of ageing on recognition memory for three-dimensional (3D) familiar objects presented to touch in a continuous paradigm. To examine changes in event-related potentials (ERPs) and brain oscillations, we recorded the EEGs of healthy groups of young (n=14; mean age=32.3 years) and older adults (n=14; mean age=65.1). Both age groups exhibited similar accuracy and exploration times when making old-new judgments. Young and older participants showed a marginally significant ERP old/new effect widely distributed over the scalp between 550-750 ms. In addition, the elders showed lower amplitude than younger participants within 1200-1500 ms. There were age-related differences in brain oscillations as measured by event-related spectral perturbation (ERSP). Older adults showed greater alpha and beta power reductions than young participants, suggesting the recruitment of additional neural resources. In contrast, the two age groups showed a reliable old/new effect in the theta band that temporarily overlapped the ERP old/new effect. The present results suggest that despite similar behavioral performance, the young and older adults recruited different neural resources to perform a haptic recognition task.

2017-01-01

This cross-sectional study investigated the age-related differences in dual-task performance both in mobility and cognitive tasks and the additive dual-task costs in a sample of older, middle-aged and young adults. 74 older adults (M = 72.63±5.57 years), 58 middle-aged adults (M = 46.69±4.68 years) and 63 young adults (M = 25.34±3.00 years) participated in the study. Participants performed different mobility and subtraction tasks under both single- and dual-task conditions. Linear regressions, repeated-measures and one-way analyses of covariance were used, The results showed: significant effects of the age on the dual and mobility tasks (p<0.05) and differences among the age-groups in the combined dual-task costs (p<0.05); significant decreases in mobility performance under dual-task conditions in all groups (p<0.05) and a decrease in cognitive performance in the older group (p<0.05). Dual-task activity affected mobility and cognitive performance, especially in older adults who showed a higher dual-task cost, suggesting that dual-tasks activities are affected by the age and consequently also mobility and cognitive tasks are negatively influenced.

This study was performed to evaluate occupational and fall injuries presenting to the ED, the risk factors associated with falls among all occupational injuries, and factors affecting prognosis. Data from ED-based Occupational Injury Surveillance System were analysed to investigate the occupational injuries. The 2147 occupational injury subjects were divided into two groups: fall (n = 213, 9.9%) and non-fall (n = 1934, 90.1%). Data including baseline and clinical characteristics were compared between the groups. The mean age was older in the fall group (46 vs 42 years old). The rate of construction site-related injury was 32% in the fall group and only 8% in the non-fall group. Injury occurrence during regular working hours (09.00 hours to 18.00 hours) was 70% in the fall group and 57% in the non-fall group. Injury severity using the Excess Mortality Ratio-adjusted Injury Severity Score (EMR-ISS) was more severe in the fall group than in the non-fall group, and days away from work were longer in the fall group than the non-fall group. Older age, compared with an age <29 years old and presence in a construction area during regular working hours were factors associated with fall injuries. Factors affecting prolonged absence for work were older age, higher EMR-ISS, fall injury and poor workplace environmental conditions. Risk factors associated with fall-related occupational injuries include older age and being at a construction area during regular working hours. Falls among occupational injuries are more severe than other injuries and result in longer work loss. © 2014 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

We aimed to define normative values for novel pressure topography metrics for high-resolution pharyngeal-esophageal manofluorography. The effects of age, gender, and bolus properties were examined. Concurrent high-resolution manometry (HRM) and videofluoroscopy data were collected from 22 younger (aged 21-40) and 22 older (aged 60-80) healthy subjects. Pressure topography was analyzed by correlating pressure domains with videofluoroscopic events. Nine pressure topography metrics of the pharyngeal and proximal esophageal swallow were extracted; four of these were also compared with previously obtained esophageal HRM studies to assess the effects of catheter diameter. Older individuals exhibited more vigorous contractility in the pharynx than did younger subjects with all bolus types, but the greatest values for both groups were with effortful swallow and on that measure the age groups were similar. Upper esophageal sphincter (UES) intrabolus pressure during sphincter opening was also greater in the older subjects. Some gender differences were observed, particularly related to proximal esophageal contractile vigor. Bolus consistency had no consistent effect. Studies using the larger catheter diameter resulted in significantly greater contractile vigor in the UES and proximal esophagus. Older adults exhibited more vigorous pharyngeal contractions than young adults, albeit within a similar range of capacity, perhaps reflecting a compensatory response to other age-related physiological changes. Greater UES intrabolus pressures observed during bolus transit in the older group likely reflect reduced UES compliance with age. Normative data on novel HRM metrics collected in this study can serve as a reference for future clinical studies. © 2016 John Wiley & Sons Ltd.

Motives of Dutch persons aged 50 years and older to accept vaccination: a qualitative study.

Elderly in several European countries are currently being vaccinated against influenza and pneumococcal disease, and various reasons have been put forward to expand these programs. To successfully immunize the older adult population, however, it is crucial for the target group to accept such interventions. This study aims to elucidate the motives of Dutch persons aged ≥ 50 years for accepting vaccination. Thirteen focus groups were composed with persons aged 50 years and older. A semi-structured topic list with open-ended questions was used to guide the focus groups. The transcripts were analyzed according the principles of thematic survey. By an inductive process, the main themes and related subthemes were extracted from the responses. Eight themes were found to play an important role in accepting vaccination: healthy aging; usefulness of vaccination in older age; risk of getting an infectious disease; vaccine characteristics; severity of the disease and its implications; the experiences of previous vaccinations; the influence of healthcare workers and other people; and the need for information. This qualitative study reveals that acceptance of vaccination is not based on a single argument. The most important one appears to be the risk of getting an infectious disease. In that light, vaccination campaigns may emphasize the susceptibility of older adults. It is also advisable to consider the usefulness of vaccination in older age as an overall argument. A tailored approach to offering vaccination may be considered. Further research would be needed to determine the relative importance of the factors identified in this study.

Motivational influences on controlled processing: moderating distractibility in older adults.

PubMed

Germain, Cassandra M; Hess, Thomas M

2007-09-01

Research has suggested that aging is associated with a decline in the efficiency of controlling processing operations. Three studies examined the moderating impact of personal relevance on age differences in one index of such operations: the ability to ignore distracting information. Young (17-26) and older (58-86) adults read a series of passages interspersed with irrelevant, distracting information, with the relevance of the passage content to these two age groups being systematically varied. For both groups, processing was more efficient and comprehension enhanced when passage relevance was high. These effects were particularly strong among older adults, a finding consistent with a growing body of data highlighting the importance of motivational factors in determining age differences in cognitive performance.

Health care in the ageing population is becoming a crucial issue, due to the quality of life. Physical activity, is of primary importance for older adults. This report compared the physical activity in two active older adults population with functionality, quality of life, and depression symptoms. A cross-sectional study was developed with 64 older adults. Physical activity was assessed through the Yale Physical Activity Survey for classification into a less activity (LA) group and a more activity (MA) group. Afterwards, the other health variables were measured through specific questionnaires: the quality of life with the EuroQol (EuroQol five dimensions questionnaire, EQ-5D), functionality with the Berg balance scale (BBS) and depression symptoms with the geriatric depression scale (GDS). There is a statistical significant difference between groups for the BBS (t=2.21; P=0.03, d=0.27). The Pearson correlation analysis shows in LA group a moderate correlation between the BBS and age (r=−0.539; P<0.01) and EQ-5D (r=0.480; P<0.01). Moreover, both groups had a moderate negative correlation between GDS and the the EQ-5D time trade-off (r=−0.543; P=0.02). Active older adults with different amounts of physical activity differ in the BBS. This functional score was higher in the MA group. When observing to quality of life, only the LA group was negatively associated with age while in both groups were associated with depression index. PMID:27419115

It is uncertain how changes in the U.S. Preventive Services Task Force breast cancer screening recommendations (from annual to biennial mammography screening in women aged 50-74 and grading the evidence as insufficient for screening in women aged 75 and older) have affected mammography use among Medicare beneficiaries. Cohort study of 12 million Medicare fee-for-service women aged 65-74 and 75 and older to measure changes in 3-year screening use, 2007-2009 (before) and 2010-2012 (after), defined by two measures-proportion screened and frequency of screening by age, race/ethnicity, and hospital referral region. Fewer women were screened, but with similar frequency after 2009 for both age groups (after vs. before: age 65-74: 60.1% vs. 60.8% screened, 2.1 vs. 2.1 mammograms per screened woman; age 75 and older: 31.7% vs. 33.6% screened, 1.9 vs. 1.9 mammograms per screened woman; all p < 0.05). Black women were the only subgroup with an increase in screening use, and for both age groups (after vs. before: age 65-74: 55.4% vs. 54.0% screened and 2.0 vs. 1.9 mammograms per screened woman; age 75 and older: 28.5% vs. 27.9% screened and 1.8 vs. 1.8 mammograms per screened woman; all p < 0.05). Regional change patterns in screening were more similar between age groups (Pearson correlation r = 0.781 for proportion screened; r = 0.840 for frequency of screening) than between black versus nonblack women (Pearson correlation r = 0.221 for proportion screened; r = 0.212 for frequency of screening). Changes in screening mammography use for Medicare women are not fully aligned with the 2009 recommendations.

To compare ages of mothers and of fathers at delivery in couples who are fertile, subfertile, and subfertile treated with assisted reproductive technology (ART) and to characterize birth outcomes in the ART population according to paternal age. Live birth deliveries in Massachusetts between July, 2004 and December, 2008 were identified from vital records and categorized by maternal fertility status and treatment as ART, subfertile or fertile. The ART births were linked to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) database to obtain cycle-specific treatment data. Parental ages were obtained from birth certificates. Age of mothers and fathers were compared using ANOVA for continuous measures and χ (2) for categories. Risks of prematurity (<37 weeks), low birthweight (<2,500 g), and low birthweight z-score (small for gestatational age, SGA) were modeled using logistic regression by categories of paternal age as adjusted odds ratios and 95 % CI. The study population included 9,092 ART, 6,238 subfertile, and 318,816 fertile deliveries. Paternal ages in the ART and subfertile groups were similar and differed significantly from those of the fertile group. Maternal age in the ART and subfertile groups averaged 5-6 years older than their fertile counterparts and fathers averaged 4-5 years older with twice as many being older than 37. The risks for prematurity, low birthweight and SGA did not increase with increasing paternal age. Fathers in ART- treated and subfertile couples are older than in their fertile counterparts. Older paternal age was not assoicated with increased risk for prematurity, low birthweight, or SGA.

To study age-related differences in neural activation during motor learning, functional magnetic resonance imaging scans were acquired from 25 young (mean 21.5-year old) and 18 older adults (mean 68.6-year old) while performing a bimanual coordination task before (pretest) and after (posttest) a 2-week training intervention on the task. We studied whether task-related brain activity and training-induced brain activation changes differed between age groups, particularly with respect to the hyperactivation typically observed in older adults. Findings revealed that older adults showed lower performance levels than younger adults but similar learning capability. At the cerebral level, the task-related hyperactivation in parietofrontal areas and underactivation in subcortical areas observed in older adults were not differentially modulated by the training intervention. However, brain activity related to task planning and execution decreased from pretest to posttest in temporo-parieto-frontal areas and subcortical areas in both age groups, suggesting similar processes of enhanced activation efficiency with advanced skill level. Furthermore, older adults who displayed higher activity in prefrontal regions at pretest demonstrated larger training-induced performance gains. In conclusion, in spite of prominent age-related brain activation differences during movement planning and execution, the mechanisms of learning-related reduction of brain activation appear to be similar in both groups. Importantly, cerebral activity during early learning can differentially predict the amplitude of the training-induced performance benefit between young and older adults.

2015-01-01

Background No formal definition for the “complex elderly” exists; moreover, these older patients with high levels of multi-morbidity are not readily identified as such at point of hospitalisation, thus missing a valuable opportunity to manage the older patient appropriately within the hospital setting. Objectives To empirically identify the complex elderly patient based on degree of multi-morbidity. Design Retrospective observational study using administrative data. Setting English hospitals during the financial year 2012–13. Subjects All admitted patients aged 65 years and over. Methods By using exploratory analysis (correspondence analysis) we identify multi-morbidity groups based on 20 target conditions whose hospital prevalence was ≥ 1%. Results We examined a total of 2788900 hospital admissions. Multi-morbidity was highly prevalent, 62.8% had 2 or more of the targeted conditions while 4.7% had six or more. Multi-morbidity increased with age from 56% (65-69yr age-groups) up to 67% (80-84yr age-group). The average multi-morbidity was 3.2±1.2 (SD). Correspondence analysis revealed 3 distinct groups of older patients. Group 1 (multi-morbidity ≤2), associated with cancer and/or metastasis; Group 2 (multi-morbidity of 3, 4 or 5), associated with chronic pulmonary disease, lung disease, rheumatism and osteoporosis; finally Group 3 with the highest level of multi-morbidity (≥6) and associated with heart failure, cerebrovascular accident, diabetes, hypertension and myocardial infarction. Conclusions By using widely available hospital administrative data, we propose patients in Groups 2 and 3 to be identified as the complex elderly. Identification of multi-morbidity patterns can help to predict the needs of the older patient and improve resource provision. PMID:26716440

This study examined and compared beliefs about the ability to remember of three groups of adults: 99 young, 97 middle-aged, and 104 older adults. The beliefs were assessed by asking participants to indicate the expected trajectory over the lifespan on a graphic rating scale, the General Beliefs about Memory Instrument (GBMI) (Lineweaver & Hertzog, 1998). The results showed the following. Although all age groups expect a decline in the ability to remember with age with the peak around 20-30 years old, older adults perceive an age-related sharp decline later in life than the other age groups do. All age groups perceive that remembering names is more affected by age than any other memory abilities. The trajectory of age decline in remembering in general coincides with that in remembering trivia. All age groups believe that the ability to remember at the age of 10 is as good as at the age of 40. All age groups responded to the scales based mainly on the abilities based on their experiences.

HIV risk and mental health problems are prevalent among female sex workers (FSWs) in China. The purpose of this research was to study age group differences in HIV risk and mental health problems in this population. In the current study, we divided a sample of 1022 FSWs into three age groups (≤ 20 years, 21-34 years, and ≥ 35 years). Results showed that among the three groups (1) older FSWs (≥ 35 years) were likely to be socioeconomically disadvantaged (e.g., rural residency, little education, employment in low-paying venues, and low monthly income); (2) older FSWs reported the highest rates of inconsistent, ineffective condom use, and sexually transmitted diseases history; (3) younger FSWs (≤ 20 years) reported the highest level of depression, suicidal thoughts and suicide attempts, regular-partner violence, and substance use; (4) all health-related risks except casual-partner violence were more prevalent among older and younger FSWs than among FSWs aged 21-34 years; and (5) age had a significant effect on all health indicators except suicide attempts after controlling for several key demographic factors. These findings indicate the need for intervention efforts to address varying needs among FSWs in different age groups. Specific interventional efforts are needed to reduce older FSWs' exposure to HIV risk; meanwhile, more attention should be given to improve FSWs' mental health status, especially among younger FSWs.

The high incidence of gastric cancer among the octogenarians and nonagenarians (oldest old; age ≥ 80 years) is emerging as an important management issue. Herein, we report both the short-term outcomes and long-term survival results of standard radical gastrectomy in this group of patients. This was a retrospective review of 164 oldest old patients (older group) and 2,258 younger patients (age <80 years; younger group) with gastric cancer who underwent curative resection between January 1994 and December 2006. Clinicopathologic data, long-term survival, and prognostic factors were analyzed. Clinical tumor stage did not differ between the two groups at the time of diagnosis. Higher Charlson comorbidity index scores (≥ 5) were observed in the older group than in the younger group; this was associated with higher postoperative morbidity (P = 0.035) and in-hospital mortality rates (P = 0.015) in the older group. At a median follow-up of 37.8 months, the overall survival rate for the older group was lower than that for the younger group (P < 0.001). However, the cumulative incidence of gastric cancer-related deaths was comparable between the two groups. Nodal involvement and metastatic to retrieved lymph node ratio were the only independent predictors of survival in the older group. Patients in the older group had a higher postoperative morbidity rate but comparable cancer-specific survival. Careful patient selection for gastrectomy is warranted in elderly patients, particularly those with high-grade nodal involvement.

BACKGROUND/STUDY CONTEXT: Older adults have more complex and differentiated views of aging than do younger adults, but less is known about age-related perceptions of Alzheimer's disease. This study investigated age-related perceptions of competence of an older adult labeled as "in good health" (healthy) or "has Alzheimer's disease" (AD), using a person-perception paradigm. It was predicted that older adults would provide more differentiated assessments of the two targets than would younger adults. Younger (n=86; 18-36 years) and older (n=66; 61-95 years) adults rated activities of daily living (ADL), instrumental activities of daily living (IADL), and memory abilities of a female target aged 75 years, described as healthy or with AD. Data on anxiety about aging, knowledge of and experience with aging and AD, knowledge of memory aging, and positive and negative biases toward aging and AD were also collected. Older adults perceived the healthy target as more capable of cognitively effortful activities (e.g., managing finances) and as possessing better memory abilities than the AD target. As predicted, these differences were greater than differences between targets perceived by younger adults. The interaction effect remained significant after statistically controlling for relevant variables, including education and gender. Additionally, exploratory analyses revealed that older adults held less positively biased views of AD than younger adults, but negatively biased views were equivalent between age groups. The results demonstrate that mere labels of "healthy" and "Alzheimer's disease" produce significant and subtle age differences in perceived competencies of older adults, and that biases towards AD vary by age group and valence. Our findings extend the person-perception paradigm to an integrative analysis of aging and AD, are consistent with models of adult development, and complement current research and theory on stereotypes of aging. Future directions for research on perceptions of aging are suggested.

The purpose of this study was to compare the effects of 16-week group exercise program on the physical function (ie, strength, flexibility, and balance) and mental health (ie, self-esteem and depression) of older elderlyl women (>or=75 years old) compared with younger elderly women (<75 years old). Exercise is crucial in maintaining older women's health and well-being. However, because most elders have at least one chronic disease, their physical function declines, so their dependence on others for instrumental daily living activities often increases. Older women typically have multiple barriers to participation in physical activities including higher disability rates. Of the total of 40 older women (older than 65 years) enrolled, 21 were older elders and 16 were younger elders. Lower body strength (using 30-second chair test), flexibility (sit-and-reach test), and static balance (ability to balance on one leg with open and closed eyes) were assessed. Self-esteem (using Rosenberg's Self-esteem Questionnaire) and depressive symptoms (using Yesavage's Geriatric Depression Scale) were assessed. Two-way analysis of variance was used to examine the differences between the 2 age groups. The intervention program was effective in improving body strength, flexibility, static balance, and self-esteem, regardless of age. Furthermore, older elders receiving the intervention program demonstrated greater improvement in self-esteem than younger elders did, although there were intervention effects in both age groups. Elderly women can realize benefits from a group exercise program that can improve their functional ability and self-esteem, both important to cardiovascular health.

To examine the relationship between cognitive function and unsafe driving acts among community-dwelling older adults with cognitive impairments. Participants (n = 160) were older residents of Obu, Japan, aged ≥65 years with cognitive impairments. They regularly drove and were assessed for the number of unsafe driving acts without adequate verification during an on-road test. We also evaluated cognitive function (attention, executive function and processing speed). Other examined variables included demographics, driving characteristics and visual condition. Participants were classified into two groups according to the number of unsafe driving acts as follows: high group (≥4 unsafe driving acts) and low group (≤3 unsafe driving acts). The high group participants were older in age (P < 0.001) and obtained a lower score on the symbol digit substitution task (P = 0.002) than the low group. The number of unsafe driving acts showed modest significant positive correlations with age (r = 0.396, P < 0.001). The symbol digit substitution task score was significantly associated with the number of unsafe driving acts (β = -0.196, P < 0.05) after adjusting for age group. Processing speed was associated with unsafe driving acts that became worse with increasing age. Future study will be required to longitudinally examine the influence of processing speed on traffic accidents for those with cognitive impairments.

Approximately 25% of individuals aged 65 years or older in the United States have diabetes mellitus. Diabetes rates in this age group are higher for Asian American and Pacific Islanders (AA/PI) than for whites. We examined racial/ethnic differences in diabetes-related potentially preventable hospitalizations (DRPH) among people aged 65 years or older for Japanese, Chinese, Filipinos, Native Hawaiians, and whites. Discharge data for hospitalizations in Hawai'i for people aged 65 years or older from December 2006 through December 2010 were compared. Annual rates of DRPH by patient were calculated for each racial/ethnic group by sex. Rate ratios (RRs) were calculated relative to whites. Multivariable models controlling for insurer, comorbidity, diabetes prevalence, age, and residence location provided final adjusted rates and RRs. A total of 1,815 DRPH were seen from 1,515 unique individuals. Unadjusted RRs for DRPH by patient were greater than 1 in all AA/PI study groups compared with whites, but were highest among Native Hawaiians and Filipinos [corrected]. In fully adjusted models accounting for higher diabetes prevalence in AA/PI groups, Native Hawaiian (adjusted rate ratio [aRR] = 1.59), Filipino (aRR = 2.26), and Japanese (aRR = 1.86) men retained significantly higher rates of diabetes-related potentially preventable hospitalizations than whites, as did Filipino women (aRR = 1.61). Native Hawaiian, Filipino, and Japanese men and Filipino women aged 65 years or older have a higher risk than whites for DRPH. Health care providers and public health programs for elderly patients should consider effective programs to reduce potentially preventable hospitalizations among Native Hawaiian, Filipino, and Japanese men and Filipino women aged 65 years or older.

Smokers of all ages can benefit by quitting, but many smokers continue to smoke. Older Greek-Australian smokers, one of the largest ethnic groups in Australia, have higher rates of smoking than other groups of older Australians. This qualitative study aimed to explore older Greek-Australians’ views about socio-cultural influences on their smoking. A snowball sampling technique was used to identify twenty Greek–Australian smokers (12 males and eight females), aged ≥ 50 years. They were recruited through the Greek Orthodox Community Center of South Australia (GOCSA). Qualitative data were collected using semi-structured face-to-face interviews. The audio-taped interviews were translated and transcribed, and then analysed using content analysis. Results suggested that smoking was considered as the “norm” by older Greek-Australian smokers. There were four groups embedded in the participants’ social networks that were reported to be important in relation to either encouraging smoking or, smoking abstinence. These support groups included: family members, friends, the Greek community, and physicians. Smokers’ family members (brothers) and friends were identified as facilitators of smoking whereas non-smoker family members (children and spouses) were reported as providing barriers to smoking. Different approaches were used by supporter groups to assist smokers to quit smoking—both planned and unplanned. Knowledge, planning of social and cultural supports, and addressing barriers to smoking cessation are a important part of health planning for older Greek-Australians. Social norms, including those arising from social interactions, and predisposing traits can influence smoking behaviour. Addressing the specific barriers to smoking cessation of older Greek-Australians is critical to addressing the risk for chronic disease in this group. PMID:25739006

The functional neuroanatomy of finger movements has been characterized with neuroimaging in young adults. However, less is known about the aging motor system. Several studies have contrasted movement-related activity in older versus young adults, but there is inconsistency among their findings. To address this, we conducted an activation likelihood estimation (ALE) meta-analysis on within-group data from older adults and young adults performing regularly paced right-hand finger movement tasks in response to external stimuli. We hypothesized that older adults would show a greater likelihood of activation in right cortical motor areas (i.e., ipsilateral to the side of movement) compared to young adults. ALE maps were examined for conjunction and between-group differences. Older adults showed overlapping likelihoods of activation with young adults in left primary sensorimotor cortex (SM1), bilateral supplementary motor area, bilateral insula, left thalamus, and right anterior cerebellum. Their ALE map differed from that of the young adults in right SM1 (extending into dorsal premotor cortex), right supramarginal gyrus, medial premotor cortex, and right posterior cerebellum. The finding that older adults uniquely use ipsilateral regions for right-hand finger movements and show age-dependent modulations in regions recruited by both age groups provides a foundation by which to understand age-related motor decline and motor disorders.

Lormetazepam, a new benzodiazepine derivative, was tested under double blind conditions in order to find the optimal dosage for different age groups of out-patients. 120 patients suffering from chronic sleep disturbance were included in the study: a younger group (age 20 to 55) and an older group (age 56 to 85 years). Four different doses were given to each age group: 0.5, 1.0, 2.0, and 3.0 mg to the younger group and 0.5, 1.0, 1.5, and 2.0 mg to the older group. A pre-placebo week (i.e. when all patients received placebo) in which baseline data were recorded preceded the two verum weeks, and these were followed by a post-placebo or withdrawal week (again all patients receiving placebo). The level of significance accepted for statistical decisions was alpha = 0.05. No differences in effects between the different doses were observed with regard to sleep pattern variables (sleep latency, sleep duration, frequency of awakenings, sleep quality, occurrence of 'bad' dreams) with the exception of sleep quality which was better in the older group than in the younger group after 0.5 mg in week 2. Considerable differences with regard to hangover feelings the next morning and during the next day (morning feelings, tranquility, alertness, and concentration), comparison of the effects of discontinuing therapy upon the above-mentioned sleep pattern variables and small differences in side effects--which were few--led to the following conclusion: --0.5 mg stood out as the best dose for the older group. --None of the dosages given to the younger group emerged clearly as superior. However, it would seem that the 1 mg dose should be the dose recommended, since fewer unfavourable scores and side effects appeared after this dose.

Age has been reported as an independent prognostic factor for melanoma-specific survival (MSS). We tested the hypothesis that age impacts the host anti-tumor immune response, accounting for age-specific survival outcomes in three unique melanoma patient cohorts. We queried the U.S. population-based Surveillance, Epidemiology, and End Results Program (SEER), the prospective tertiary care hospital-based Interdisciplinary Melanoma Cooperative Group (IMCG) biorepository, and the Cancer Genome Atlas (TCGA) biospecimen database to test the association of patient age at time of melanoma diagnosis with clinicopathologic features and survival outcomes. Age groups were defined as ≤45 (young), 46-65 (intermediate), and >65 (older). Each age group in the IMCG and TCGA cohorts was stratified by tumor infiltrating lymphocyte (TIL) measurements and tested for association with MSS. Differential expression of 594 immunoregulatory genes was assessed in a subset of primary melanomas in the IMCG and TCGA cohorts using an integrative pathway analysis. We analyzed 304, 476 (SEER), 1241 (IMCG), and 292 (TCGA) patients. Increasing age at melanoma diagnosis in both the SEER and IMCG cohorts demonstrated a positive correlation with tumor thickness, ulceration, stage, and mortality, however age in the TCGA cohort did not correlate with mortality. Older age was associated with shorter MSS in all three cohorts. When the young age group in both the IMCG and TCGA cohorts was stratified by TIL status, there were no differences in MSS. However, older IMCG patients with brisk TILs and intermediate aged TCGA patients with high lymphocyte scores (3-6) had improved MSS. Gene expression analysis revealed top pathways (T cell trafficking, communication, and differentiation) and top upstream regulators (CD3, CD28, IFNG, and STAT3) that significantly changed with age in 84 IMCG and 43 TCGA primary melanomas. Older age at time of melanoma diagnosis is associated with shorter MSS, however age's association with clinicopathologic features is dependent upon specific characteristics of the study population. TIL as a read-out of the host immune response may have greater prognostic impact in patients older than age 45. Recognition of age-related factors negatively impacting host immune responses may provide new insights into therapeutic strategies for the elderly.

While much of the research on aging and driving has focused on sensory and motor changes, little is known about older drivers and the actual self-regulation adjustments they employ to continue driving safely. This research looks at how older drivers have made changes to driving patterns and behaviors that have allowed them to continue to drive without compromising their perceived safety, independence, and quality of life. Nine focus groups were held with older men and women aged 58 to 89 years. Some of the major themes that emerged were the following: older adults are very aware of age-related changes to driving; they perceive that self-regulation behaviors change with age; and they view transportation alternatives as limited or nonexistent. Policy implications include developing functional transit programs for older adults and car manufacturer training workshops to educate older adults on the safety features of newly purchased automobiles.

Younger and older adults' beliefs about the experience and expression of emotions across the life span.

Although theorists acknowledge that beliefs about emotions may play a role in age-related emotion behavior, no research has explored these beliefs. This research examined beliefs about the experience and expression of emotions across the life span, especially across the adult years. Younger and older adults rated the extent to which infants, children, adolescents, young adults, middle-aged adults, and older adults were likely to experience and express a range of emotions. Younger and older adults held similar beliefs about the course of emotions across the life span. Moreover, these beliefs differed across emotion categories. In particular, although older adults were believed to experience and express fewer highly charged, negative emotions, they were expected to be more likely to experience and express positive, low arousal emotions, as well as negative, low arousal emotions. The experience and expression of positive, high arousal emotions were seen as more characteristic of very young age groups as opposed to older age groups. These findings beg questions about if and how beliefs about emotion may affect age-related emotion regulation strategies and other everyday emotion-focused behaviors, as well as social reactions to older adults observed experiencing and expressing particular types of emotions. © The Author 2013.

In 2008 the US Preventive Services Task Force recommended against screening men ages 75 and older for prostate cancer. Using Medicare Current Beneficiary Survey Access to Care files and linked claims, we compared trends in prostate-specific antigen (PSA) testing rates between men ages 75 and older and men ages 65–74. We estimate that the revised recommendation led to a 7.9-percentage-point decline in annual PSA testing rates over two years among men ages 75 and older. Although 42 percent of men in this age group continue to receive PSA tests, our results highlight the potential of guidelines with negative recommendations to reduce the use of low-value medical care.

Perceptual restoration of degraded speech is preserved with advancing age.

Cognitive skills, such as processing speed, memory functioning, and the ability to divide attention, are known to diminish with aging. The present study shows that, despite these changes, older adults can successfully compensate for degradations in speech perception. Critically, the older participants of this study were not pre-selected for high performance on cognitive tasks, but only screened for normal hearing. We measured the compensation for speech degradation using phonemic restoration, where intelligibility of degraded speech is enhanced using top-down repair mechanisms. Linguistic knowledge, Gestalt principles of perception, and expectations based on situational and linguistic context are used to effectively fill in the inaudible masked speech portions. A positive compensation effect was previously observed only with young normal hearing people, but not with older hearing-impaired populations, leaving the question whether the lack of compensation was due to aging or due to age-related hearing problems. Older participants in the present study showed poorer intelligibility of degraded speech than the younger group, as expected from previous reports of aging effects. However, in conditions that induce top-down restoration, a robust compensation was observed. Speech perception by the older group was enhanced, and the enhancement effect was similar to that observed with the younger group. This effect was even stronger with slowed-down speech, which gives more time for cognitive processing. Based on previous research, the likely explanations for these observations are that older adults can overcome age-related cognitive deterioration by relying on linguistic skills and vocabulary that they have accumulated over their lifetime. Alternatively, or simultaneously, they may use different cerebral activation patterns or exert more mental effort. This positive finding on top-down restoration skills by the older individuals suggests that new cognitive training methods can teach older adults to effectively use compensatory mechanisms to cope with the complex listening environments of everyday life.

BACKGROUND Lower limb mobility disabilities are well understood in older people, but the causes in middle age have attracted little attention. OBJECTIVES To estimate the prevalence of mobility disabilities among noninstitutionalized adults in England and to compare the disabling symptoms reported by middle-aged and older people. DESIGN Cross-sectional data from the 2002 English Longitudinal Study of Ageing (ELSA). Mobility disability was identified by level of reported difficulty walking a quarter mile. PARTICIPANTS Eleven thousand two hundred sixteen respondents aged 50 years and older living in private households in 2002. RESULTS The prevalence of difficulty walking a quarter mile increases sharply with age, but even in the middle-aged (50 to 64 years age-group) 18% (95% confidence interval [CI]: 16% to 19%) of men and 19% (95% CI: 17% to 20%) of women reported some degree of difficulty. Of the 16 main symptoms reported as causing mobility disability in middle age, 2 dominated: pain in the leg or the foot (43%; 95% CI: 40% to 46%) and shortness of breath/dyspnea (21%; 95% CI: 18% to 23%). Fatigue or tiredness, and stability problems were cited by only 5% and 6%, respectively. These proportions were slightly different from those in the 65 to 79-year age group: 40%, 23%, 6%, and 8%, respectively. CONCLUSIONS Mobility (walking) disabilities in the middle-aged are relatively common. The symptoms reported as causes in this age group differ little from those reported by older groups, and are dominated by lower limb pain and shortness of breath. More clinical attention paid to disabling symptoms may lead to disability reductions in later life. PMID:16970558

We analyze the relationship between age of survival, morbidity, and disability among centenarians (age 100-104 years), semisupercentenarians (age 105-109 years), and supercentenarians (age 110-119 years). One hundred and four supercentenarians, 430 semisupercentenarians, 884 centenarians, 343 nonagenarians, and 436 controls were prospectively followed for an average of 3 years (range 0-13 years). The older the age group, generally, the later the onset of diseases, such as cancer, cardiovascular disease, dementia, and stroke, as well as of cognitive and functional decline. The hazard ratios for these individual diseases became progressively less with older and older age, and the relative period of time spent with disease was lower with increasing age group. We observed a progressive delay in the age of onset of physical and cognitive function impairment, age-related diseases, and overall morbidity with increasing age. As the limit of human life span was effectively approached with supercentenarians, compression of morbidity was generally observed.

2004-12-15

A battery of tasks, i.e. beam walking, open field, tightrope, radial six-arm water maze (RAWM), novel-object recognition and olfactory discrimination, was used to determine whether there was age- and sex-related memory deterioration in Kunming (KM) mice, and whether these tasks are independent or correlated with each other. Two age groups of KM mice were used: a younger group (7-8 months old, 12 males and 11 females) and an older group (17-18 months old, 12 males and 12 females). The results showed that the spatial learning ability and memory in the RAWM were lower in older female KM mice relative to younger female mice and older male mice. Consistent with this, in the novel-object recognition task, a non-spatial cognitive task, older female mice but not older male mice had impairment of short-term memory. In olfactory discrimination, another non-spatial task, the older mice retained this ability. Interestingly, female mice performed better than males, especially in the younger group. The older females exhibited sensorimotor impairment in the tightrope task and low locomotor activity in the open-field task. Moreover, older mice spent a longer time in the peripheral squares of the open-field than younger ones. The non-spatial cognitive performance in the novel-object recognition and olfactory discrimination tasks was related to performance in the open-field, whereas the spatial cognitive performance in the RAWM was not related to performance in any of the three sensorimotor tasks. These results suggest that disturbance of spatial learning and memory, as well as selective impairment of non-spatial learning and memory, existed in older female KM mice.

Traditionally, studies investigating the functional implications of age-related structural brain alterations have focused on higher cognitive processes; by increasing stimulus load, these studies assess behavioral and neurophysiological performance. In order to understand age-related changes in these higher cognitive processes, it is crucial to examine changes in visual and auditory processes that are the gateways to higher cognitive functions. This study provides evidence for age-related functional decline in visual and auditory processing, and regional alterations in functional brain processing, using non-invasive neuroimaging. Using functional magnetic resonance imaging (fMRI), younger (n=11; mean age=31) and older (n=10; mean age=68) adults were imaged while observing flashing checkerboard images (passive visual stimuli) and hearing word lists (passive auditory stimuli) across varying stimuli presentation rates. Younger adults showed greater overall levels of temporal and occipital cortical activation than older adults for both auditory and visual stimuli. The relative change in activity as a function of stimulus presentation rate showed differences between young and older participants. In visual cortex, the older group showed a decrease in fMRI blood oxygen level dependent (BOLD) signal magnitude as stimulus frequency increased, whereas the younger group showed a linear increase. In auditory cortex, the younger group showed a relative increase as a function of word presentation rate, while older participants showed a relatively stable magnitude of fMRI BOLD response across all rates. When analyzing participants across all ages, only the auditory cortical activation showed a continuous, monotonically decreasing BOLD signal magnitude as a function of age. Our preliminary findings show an age-related decline in demand-related, passive early sensory processing. As stimulus demand increases, visual and auditory cortex do not show increases in activity in older compared to younger people. This may negatively impact on the fidelity of information available to higher cognitive processing. Such evidence may inform future studies focused on cognitive decline in aging.

Life-crossroads on stage: integrating life review and drama therapy for older adults.

PubMed

Keisari, Shoshi; Palgi, Yuval

2017-10-01

This paper examines the contribution of a new group of therapeutic interventions for older adults, based on a rudimentary life-review intervention. The intervention includes narrative elements together with drama therapy. The current study examines the influence of this therapeutic intervention on key indicators of mental health and psychological well-being among older adults. Fifty-five people (n = 55), ranging in age from 62 to 93, participated in a before-after study design. The following indices - meaning in life, self-acceptance, relationships with others, depressive symptoms, and experience of successful aging - were compared between an intervention group (n = 27) and a care-as-usual control group (n = 28). Repeated measures analyses of variance showed a significant improvement over time in the experimental group. In addition, results also showed time-group interaction regarding the treatment's effectiveness for self-acceptance, relationships with others, sense of meaning in life, sense of successful aging, and depressive symptoms. Our findings confirm that the new therapeutic intervention, which integrates life-review with drama therapy, increases self-acceptance, relationships with others, sense of meaning in life, and sense of successful aging; in turn, it also decreases depressive symptoms among older adults. The contribution of this research is based on the development of a therapeutic intervention that combines narrative together with drama therapy tools, which can be used in focused and short-term group treatments with the elderly.

The prevalence of age-related cognitive decline will increase due to graying of the global population. The goal of the present study was to test whether playing online cognitive training games can improve cognitive control (CC) in healthy older adults. Fifty-four older adults (age 60–77) played five different cognitive training games online for 30 min a day over a period of seven weeks (game group). Another group of 20 older adults (age 61–73) instead answered quiz questions about documentaries online (documentary group). Transfer was assessed by means of a cognitive test battery administered before and after the intervention. The test battery included measures of working memory updating, set shifting, response inhibition, attention, and inductive reasoning. Compared with the documentary group, the game group showed larger improvement of inhibition (Stop-Signal task) and inductive reasoning (Raven-SPM), whereas the documentary group showed more improvement in selective attention (UFoV-3). These effects qualify as transfer effects, because response inhibition, inductive reasoning and selective attention were not targeted by the interventions. However, because seven other indicators of CC did not show benefits of game training and some of those that did suffered from potential baseline differences, the study as a whole provides only modest support for the potential of videogame training to improve CC in healthy older adults.

Age-related patterns in social networks among European Americans and African Americans: implications for socioemotional selectivity across the life span.

PubMed

Fung, H H; Carstensen, L L; Lang, F R

2001-01-01

Socioemotional selectivity theory contends that as people become increasingly aware of limitations on future time, they are increasingly motivated to be more selective in their choice of social partners, favoring emotionally meaningful relationships over peripheral ones. The theory hypothesizes that because age is negatively associated with time left in life, the social networks of older people contain fewer peripheral social partners than those of their younger counterparts. This study tested the hypothesis among African Americans and European Americans, two ethnic groups whose social structural resources differ. Findings confirm the hypothesis. Across a wide age range (18 to 94 years old) and among both ethnic groups, older people report as many emotionally close social partners but fewer peripheral social partners in their networks as compared to their younger counterparts. Moreover, a greater percentage of very close social partners in social networks is related to lower levels of happiness among the young age group, but not among the older age groups. Implications of findings for adaptive social functioning across the life span are discussed.

To understand how demographic variables and depression symptoms relate to the prevalence of wellness, resilience, and age perception within a sample of community-dwelling older adults. In all, 200 residents across 12 senior housing sites were surveyed. Research questions included the following: (1) Do group differences exist in wellness, resilience, and age perception based on age, sex, race, education, and depression symptoms? (2) Which profile of variables is most strongly associated with self-rated depression among older adults? Multivariate analyses of variance were used to examine group differences. A discriminant analysis demonstrated which variables comprised the profile of individuals who ascribed to depression symptoms. Younger respondents (i.e., age 55-70) had significantly lower levels of wellness (η 2 = .034) and resilience (η 2 = .052). Respondents suffering from depression symptoms had lower levels of wellness (η 2 = .155), resilience (η 2 = .163), and positive age perception (η 2 = .067) and higher rates of negative age perception (η 2 = .052). The discriminant analysis correctly categorized 75.3% of the cases related to depression symptoms, and resilience and certain forms of wellness were most relevant. The current study sheds light into within-group differences in wellness, resilience, and age perception that depend on variables such as age and depression.

Background Antiretroviral therapy has improved survival for HIV-1-infected individuals. The neuroepidemiologic implications of HIV-1 in an aging population are not well known, particularly the prevalence of HIV-associated dementia (HAD). Methods The authors report a baseline cross-sectional analysis of 202 HIV-1-seropositive individuals enrolled into one of two groups of the Hawaii Aging with HIV Cohort: older (50 or more years old, n = 106) and younger (20 to 39 years old, n = 96). Neuropsychological, neurologic, medical, and laboratory data were obtained at enrollment. Participant cognitive status was classified (research case definitions) using American Academy of Neurology (1991) criteria in a consensus conference of physicians and neuropsychologists. Results HAD was more frequent in older (25.2%) compared to younger (13.7%) individuals (p = 0.041) corresponding to an OR of 2.13 (95% CI: 1.02 to 4.44) for the older compared to the younger group. After adjusting for education, race, substance dependence, antiretroviral medication status, viral load, CD4 lymphocyte count, and Beck Depression Inventory score, the odds of having HAD among individuals in the older group was 3.26 (1.32 to 8.07) times that of the younger group. Conclusions Older age is associated with increased HAD in this HIV-1 cohort. Underlying mechanisms are unclear but do not appear related to duration of HIV-1 infection. PMID:15365130

Previous studies documented significant increase in overall survival for metastatic colorectal cancer (CRC) since the late 1990s coinciding with the introduction and dissemination of new treatments. We examined whether this survival increase differed across major racial/ethnic populations and age groups. We identified patients diagnosed with primary metastatic colorectal cancer during 1992-2009 from 13 population-based cancer registries of the National Cancer Institute's Surveillance, Epidemiology, and End Results Program, which cover about 14 % of the US population. The 5-year cause-specific survival rates were calculated using SEER*Stat software. From 1992-1997 to 2004-2009, 5-year cause-specific survival rates increased significantly from 9.8 % (95 % CI 9.2-10.4) to 15.7 % (95 % CI 14.7-16.6) in non-Hispanic whites and from 11.4 % (95 % CI 9.4-13.6) to 17.7 % (95 % CI 15.1-20.5) in non-Hispanic Asians, but not in non-Hispanic blacks [from 8.6 % (95 % CI 7.2-10.1) to 9.8 % (95 % CI 8.1-11.8)] or Hispanics [from 14.0 % (95 % CI 11.8-16.3) to 16.4 % (95 % CI 14.0-19.0)]. By age group, survival rates increased significantly for the 20-64-year age group and 65 years or older age group in non-Hispanic whites, although the improvement in the older non-Hispanic whites was substantially smaller. Rates also increased in non-Hispanic Asians for the 20-64-year age group although marginally nonsignificant. In contrast, survival rates did not show significant increases in both younger and older age groups in non-Hispanic blacks and Hispanics. Non-Hispanic blacks, Hispanics, and older patients diagnosed with metastatic CRC have not equally benefitted from the introduction and dissemination of new treatments.

2010-01-01

Although much has been learned in recent decades about the deterioration of muscular strength, gait adaptations, and sensory degradation among older adults, little is known about how these intrinsic changes affect biomechanical parameters associated with slip-induced fall accidents. In general, the objective of this laboratory study was to investigate the process of initiation, detection, and recovery of inadvertent slips and falls. We examined the initiation of and recovery from foot slips among three age groups utilizing biomechanical parameters, muscle strength, and sensory measurements. Forty-two young, middle-age, and older participants walked around a walking track at a comfortable pace. Slippery floor surfaces were placed on the track over force platforms at random intervals without the participants’ awareness. Results indicated that younger participants slipped as often as the older participants, suggesting that the likelihood of slip initiation is similar across all age groups; however, older individuals’ recovery process was much slower and less effective. The ability to successfully recover from a slip (thus preventing a fall) is believed to be affected by lower extremity muscle strength and sensory degradation among older individuals. Results from this research can help pinpoint possible intervention strategies for improving dynamic equilibrium among older adults. PMID:16553061

2014-01-01

Higher prevalence of multiple illnesses and cognitive impairment among older patients pose a risk of comprehension difficulties, potentially leading to medication errors. Therefore, the objective of this study was to investigate comprehension of discharge instructions among older patients admitted to a Quick Diagnostic Unit (QDU). One hundred and two patients discharged from the QDU answered a questionnaire covering understanding of their hospitalization and discharge plan. Patients' ability to recall discharge instructions and awareness of comprehension deficits, ie, ability to identify the misconceived information, were evaluated by comparing the questionnaires with the discharge letters. The population was divided into an older group (age ≥65 years) and a younger group. The older group (n=40) was less able to recall correct medication instructions when compared to the younger group (54% versus 78%, respectively; P=0.02). In multiple logistic regression analysis, correct recall of medication instructions was 4.2 times higher for the younger group compared to the older group (odds ratio 4.2, 95% confidence interval 1.5-11.9, P=0.007) when adjusted for sex and education. The older patients were less aware of their own comprehension deficits, and in respect to medication instructions awareness decreased 6.1% for each additional year of age (odds ratio 0.939, 95% confidence interval 0.904-0.98, P=0.001) when adjusted for sex and education. Older patients were less able to recall correct medication instructions and less aware of their comprehension deficits after discharge from a QDU. The findings of the present study emphasize the importance of thorough communication and follow-up when treating older patients.

Background. Previous retrospective studies have shown that physical functioning in older cancer survivors is affected after treatment, yet prospective data are lacking. The aim of this study was to assess change in physical functioning in different age groups of patients with hormone receptor-positive breast cancer who were enrolled in the Tamoxifen Exemestane Adjuvant Multinational (TEAM) phase III trial. Methods. Two physical parameters were assessed. Physical functioning was assessed using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire 1 year (T1) and 2 years (T2) after diagnosis. Physical activity was measured in metabolic equivalent of task (MET) hours/week at T1 and T2. Physical activity before diagnosis (T0) was assessed retrospectively at the T1 questionnaire. Patients were divided into three age groups: <60, 60–69, and ≥70 years. Decline in physical functioning was assessed using linear regression analysis. Differences in mean values of physical activity levels were calculated using repeated-measures one-way analysis of variance. Results. A total of 431 patients were included for analysis. In all age groups, physical activity levels at T1 and T2 were significantly lower than prediagnostic physical activity levels (T0) (p < .001 for all age groups). Age ≥70 years was independently associated with decline in physical functioning between T1 and T2 (β = −4.62, 95% confidence interval −8.73 to −0.51, p = .028). Conclusion. Patients aged 70 years or older treated with breast surgery and adjuvant hormonal therapy did not improve between years 1 and 2 after diagnosis to the same extent as did younger patients. Implications for Practice: Although older patients constitute a large share of the breast cancer population, little is known about the effect and consequences of treatment of breast cancer in this specific age group. This study revealed that, unlike younger patients, older patients do not regain their physical abilities after surgical and adjuvant treatment for breast cancer. In older adults, the effect of treatment on physical functioning and independency could be more relevant than survival outcomes. Clinicians and older patients should be aware of the impact of treatment on physical functioning and prevent older patients from experiencing physical decline, which could lead to institutionalization and loss of independence. There is a need for age-specific guidelines that take into account the heterogeneity of the older population and for evidence-based treatment that focuses not only on cancer-specific outcomes but also on the consequences of treatment for physical and cognitive functioning and quality of life.

As of 2012, 810 million people worldwide were older than 60 y, accounting for 11% of the population. That number is expected to rise to 2 billion by 2050 or to 22% of the overall population. As a result, a growing need exists to understand the factors that promote mental and physical health in older populations. The purpose of this study was to develop a healthy aging program for older adults and to measure the changes from baseline to the end of the program in participants' relevant psychosocial outcomes (ie, self-efficacy and morale). The study's healthy aging mind-body intervention (MBI) was adapted from the Relaxation Response Resiliency Program (3RP) at the Benson-Henry Institute for Mind Body Medicine, which incorporates elements from the fields of stress management, cognitive behavioral therapy, and positive psychology. That program was modified with examples and exercises targeted to an older population and evaluated in the current single-arm pilot study. The program took place at the Massachusetts General Hospital (MGH). The 9-wk healthy aging MBI was developed for participants aged 65 y and older. Fifty-one older adults from the surrounding community participated in the study's groups. A new intervention group began the program every 3 mo, with a maximum of 12 individuals per group. For each group, the MBI consisted of weekly 90-min sessions for 9 consecutive wk, directed by a psychologist. The program included sessions that taught participants (1) a variety of methods to elicit the relaxation response (RR), (2) the practice of adaptive coping and cognitions, (3) behaviors necessary to create a healthy lifestyle, and (4) methods of building social support. The research team chose to focus on 2 psychological variables of interest for aging populations: morale and self-efficacy. The study used 2 questionnaires to measure those outcomes, the Philadelphia Geriatric Center Morale Scale (PGCMS), a multidimensional measure of the psychological state of older people, and the Coping Self-efficacy Scale (CSES), a measure that addresses the multiple dimensions of self-efficacy. Data from 5 intervention groups were combined for the current analysis. Forty-six participants enrolled and completed questionnaires. Of those participants, 41 attended at least 7 of the 9 sessions. Significant increases in self-efficacy and morale were observed for program completers. After a highly conservative sensitivity analysis, the change for the measure of self-efficacy remained significant, and the change for the measure of morale trended toward significance. The study's healthy aging program appears to be a feasible intervention for older adults, with the potential to increase levels of self-efficacy and morale in participants. Further research is warranted to determine its effects on other psychosocial outcomes and health care utilization in aging populations.

Vasodilatory responsiveness to adenosine triphosphate in ageing humans.

Endothelium-dependent vasodilatation is reduced with advancing age in humans, as evidenced by blunted vasodilator responsiveness to acetylcholine (ACh). Circulating adenosine triphosphate (ATP) has been implicated in the control of skeletal muscle vascular tone during mismatches in oxygen delivery and demand (e.g. exercise) via binding to purinergic receptors (P2Y) on the endothelium evoking subsequent vasodilatation, and ageing is typically associated with reductions in muscle blood flow under such conditions. Therefore, we tested the hypothesis that ATP-mediated vasodilatation is impaired with age in healthy humans. We measured forearm blood flow (venous occlusion plethysmography) and calculated vascular conductance (FVC) responses to local intra-arterial infusions of ACh, ATP, and sodium nitroprusside (SNP) before and during ascorbic acid (AA) infusion in 13 young and 13 older adults. The peak increase in FVC to ACh was significantly impaired in older compared with young adults (262 ± 71% vs. 618 ± 97%; P < 0.05), and this difference was abolished during AA infusion (510 ± 82% vs. 556 ± 71%; not significant, NS). In contrast, peak FVC responses were not different between older and young adults to either ATP (675 ± 105% vs. 734 ± 126%) or SNP (1116 ± 111% vs. 1138 ± 148%) and AA infusion did not alter these responses in either age group (both NS). In another group of six young and six older adults, we determined whether vasodilator responses to adenosine and ATP were influenced by P1-receptor blockade via aminophylline. The peak FVC responses to adenosine were not different in young (350 ± 65%) versus older adults (360 ± 80%), and aminophylline blunted these responses by ∼50% in both groups. The peak FVC responses to ATP were again not different in young and older adults, and aminophylline did not impact the vasodilatation in either group. Thus, in contrast to the observed impairments in ACh responses, the vasodilatory response to exogenous ATP is not reduced with age in healthy humans. Further, our data also indicate that adenosine mediated vasodilatation is not reduced with age, and that ATP-mediated vasodilatation is independent of P1-receptor stimulation in both young and older adults.

Age differences in vocal emotion perception: on the role of speaker age and listener sex.

Older adults have greater difficulty than younger adults perceiving vocal emotions. To better characterise this effect, we explored its relation to age differences in sensory, cognitive and emotional functioning. Additionally, we examined the role of speaker age and listener sex. Participants (N = 163) aged 19-34 years and 60-85 years categorised neutral sentences spoken by ten younger and ten older speakers with a happy, neutral, sad, or angry voice. Acoustic analyses indicated that expressions from younger and older speakers denoted the intended emotion with similar accuracy. As expected, younger participants outperformed older participants and this effect was statistically mediated by an age-related decline in both optimism and working-memory. Additionally, age differences in emotion perception were larger for younger as compared to older speakers and a better perception of younger as compared to older speakers was greater in younger as compared to older participants. Last, a female perception benefit was less pervasive in the older than the younger group. Together, these findings suggest that the role of age for emotion perception is multi-faceted. It is linked to emotional and cognitive change, to processing biases that benefit young and own-age expressions, and to the different aptitudes of women and men.

Research on the impact of natural disasters on the mental health of older adults finds both vulnerabilities and resilience. We report on the rates of clinically significant depression among older adults (aged ≥60 years) living in areas affected by Hurricane Sandy in 2012 and the factors associated with mental health need. The Sandy Mobilization, Assessment, Referral and Treatment for Mental Health (SMART-MH) program integrates community outreach and needs assessments to identify older adults with mental health and aging service needs. Older adults with significant anxiety or depressive symptoms were offered short-term psychotherapy. Social service referrals were made directly to community agencies. All SMART-MH activities were offered in Spanish, Russian, Mandarin/Cantonese, and English. Across the full sample, 14% of participants screened positive for depression. Hurricane Sandy stressors predicted increased odds of depression, including storm injury, post-storm crime, and the total count of stressors. Outcomes varied significantly by age group, such that all Sandy-related variables remained significant for younger-old adults (aged 60-74 years), whereas only the loss of access to medical care was significant for older-old adults (aged ≥75 years). Storm-affected communities show higher rates of depressive symptoms than seen in the general population, with storm stressors affecting mental health needs differentially by age group.

2015-01-01

Research on aging has shown a significant decline in ToM after 65 years of age. Despite these age-related difficulties, no study has yet investigated the possibility to improve ToM in older adults. To address this gap we tested the efficacy of a conversation-based ToM training with age-appropriate ToM tasks and its transfer effects on metamemory. We examined 72 older adults (Mage=67.61 years, SD=6.39 years) assigned to three training conditions: a ToM training, a physical-conversation training and a social-contact group. All participants took part in two 2-h testing and to two 2-h training sessions. Results showed that after the intervention, older adults in the ToM training group improved their mental states' understanding significantly more than participants in the physical-conversation training and in the social-contact groups. Crucially, the positive effect of the ToM intervention generalized to metamemory knowledge. This is the first study investigating the efficacy of a ToM training and its transfer effect on metacognition in older adults. From a theoretical point of view, it supports the relation between ToM and metamemory. Practical implications of these data are discussed. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Me Time, or We Time? Age Differences in Motivation for Exercise.

Steltenpohl, Crystal N; Shuster, Michael; Peist, Eric; Pham, Amber; Mikels, Joseph A

2018-04-23

Increasing exercise continues to be an important health issue for both older and younger adults. Researchers have suggested several methods for increasing exercise motivation. Socioemotional selectivity theory (SST) posits that people's motivation shift from future-oriented instrumental goals to present-oriented emotionally meaningful goals as we age, which provides insight into how people's motivations for exercise may differ for older versus younger adults. The aim of our study was to examine how exercise motivation differs for older versus younger adults. Older (greater than 59 years old) and younger (aged 18-26 years) adults participated in focus groups. They discussed exercise motivation (or lack thereof), motivators and barriers to exercise, and preferences about when, where, and with whom they exercise. Focus group transcripts were analyzed using direct content analysis and iterative categorization. Consistent with SST, younger adults generally preferred to exercise alone to achieve instrumental fitness goals, whereas older adults preferred to exercise with others. Additionally, older adults tend to consider peripheral others (e.g., strangers, acquaintances), as a positive rather than a negative influence. SST provides a framework for exploring age-related shifts in exercise motivation. Additionally, the positivity effect was reflected in how older adults evaluated the influence of peripheral others. Motivational messages could be tailored to increase health behavior changes by focusing on instrumental exercise goals for younger adults and exercise focused on meaningful relationships for older adults.

Education Inequalities in Health Among Older European Men and Women: The Role of Active Aging.

Arpino, Bruno; Solé-Auró, Aïda

2017-08-01

We assessed whether education inequalities in health among older people can be partially explained by different levels of active aging among educational groups. We applied logistic regression and the Karlson, Holm, & Breen (KHB) decomposition method using the 2010 and 2012 waves of the Survey of Health, Ageing and Retirement in Europe on individuals aged 50+ years ( N = 27,579). Active aging included social participation, paid work, and provision of grandchild care. Health was measured by good self-perceived health, low number of depressive symptoms, and absence of limitations because of health in activities people usually do. We found a positive educational gradient for each of the three health measures. Up to a third of the health gaps between high and low educated were associated with differences in engagement in active aging activities. Policies devoted at stimulating an active participation in society among older people should be particularly focused on lower educated groups.

Does Central Vision Loss Impair Visual Search Performance of Adults More than Children?

In general, young adults with normal vision show the best visual search performance when compared with children and older adults. Through our study, we show that this trend is not observed in individuals with vision impairment. An interaction effect of vision impairment with visual development and aging is observed. Performance in many visual tasks typically shows improvement with age until young adulthood and then declines with aging. Using a visual search task, this study investigated whether a similar age effect on performance is present in people with central vision loss. A total of 98 participants, 37 with normal sight (NS) and 61 with visual impairment (VI) searched for targets in 150 real-world digital images. Search performance was quantified by an integrated measure combining speed and accuracy. Participant ages ranged from 5 to 74 years, visual acuity from -0.14 (20/14.5) to 1.16 logMAR (20/290), and log contrast sensitivity (CS) from 0.48 to 2.0. Data analysis was performed with participants divided into three age groups: children (aged <14 years, n = 25), young adults (aged 14 to 45 years, n = 47), and older adults (aged >45 years, n = 26). Regression (r = 0.7) revealed CS (P < .001) and age (P = .003) were significant predictors of search performance. Performance of VI participants was normalized to the age-matched average performance of the NS group. In the VI group, it was found that children's normalized performance (52%) was better than both young (39%, P = .05) and older (40%, P = .048) adults. Unlike NS participants, young adults in the VI group may not have search ability superior to children with VI, despite having the same level of visual functions (quantified by visual acuity and CS). This could be because of vision impairment limiting the developmental acquisition of the age dividend for peak performance. Older adults in the VI group had the worst performance, indicating an interaction of aging.

The importance of sleep for cognition in young adults is well established, but the role of habitual sleep behavior in cognition across the adult life span remains unknown. We examined the relationship between sleep continuity and total sleep time as assessed with a sleep-detection device, and cognitive performance using a battery of tasks in young (n = 59, mean age = 23.05) and older (n = 53, mean age = 62.68) adults. Across age groups, higher sleep continuity was associated with better cognitive performance. In the younger group, higher sleep continuity was associated with better working memory and inhibitory control. In the older group, higher sleep continuity was associated with better inhibitory control, memory recall, and verbal fluency. Very short and very long total sleep time was associated with poorer working memory and verbal fluency, specifically in the younger group. Total sleep time was not associated with cognitive performance in any domains for the older group. These findings reveal that sleep continuity is important for executive function in both young and older adults, but total sleep time may be more important for cognition in young adults.

A growing number of older adults are undergoing liver transplantation (LT) in the US. In some settings, it is thought that adherence declines with age. This retrospective study examined adherence and clinical outcomes in older versus younger adult LT recipients. Medical records of adult LT recipients from 2009–2012 from a single urban center were reviewed. The medication level variability index (MLVI) was the pre-defined primary outcome, with nonadherence defined as MLVI >2.5. The secondary outcome was incidence of rejection. Outcomes were evaluated starting one year post-LT until 2015. 42/248 patients were ≥65 at transplant. Older adults had significantly better adherence than younger ones (65% ≥65 were adherent vs. 42% younger adults; Chi-Square two-tailed p=0.02). Survival analyses of rejection between age groups censored by time since transplant showed no difference among the four age groups (χ2 = 0.84, p=0.84). Older age was not found to be a risk factor for reduced adherence or graft rejection in patients surviving at least one year post-LT. PMID:28370346

New Zealand as a society is ageing. This translates to an increasing number of people particularly women, over the age of 85 years. Despite many older women living alone, they are often perceived by both society and health professionals as frail and dependent. This qualitative study was designed to explore and describe experiences of older women who lived alone in the community. A qualitative descriptive methodology underpinned the study. A sample of five older women who lived alone in their own homes was interviewed. Data were analysed using a general inductive approach. Three themes emerged which reflected the reality of living by themselves: "active participation", "keeping control", and" healthy living". The information gained from describing the lives of this group of women suggests that many older women are able to live full and successful independent lives in the community. This research provides nursing with a better understanding of the realities for older women who live alone. Finally, this paper will provide nurses with some ideas about how best to support this group of people as they age.

Enhancing the participation of Chinese older women in biobanking efforts is important for precision medicine efforts, as underrepresented groups risk benefiting less than others from medical advancements in individualized therapies. Focusing on a sample of Chinese older women in Chicago's Chinatown, this qualitative study seeks to describe attitudes toward, and barriers and facilitators of, participation in biospecimen research. We conducted six focus groups among Chinese-speaking adult women age 45 and above. Focus groups were transcribed, coded, and analyzed for emergent themes. Forty-seven women participated in focus groups, the majority (66.0%) were age 66 and over and half (50.1%) had less than a high school education. Participants expressed predominantly positive attitudes toward biospecimen research, but also identified multifaceted barriers to participation that included cultural beliefs of the body, perceived physical and privacy risks, as well as perceptions related to aging. Use of minimally invasive biospecimen collection and education to promote awareness of biospecimen research were suggested facilitators to increasing biospecimen research participation. Culturally and linguistically isolated populations like Chinese older women are at risk of exclusion from advancements in precision medicine. Our findings provide cultural insights for tailoring interventions for Chinese older women to increase knowledge, change attitudes, and increase intention and participation in biospecimen research. We also highlight the need for individual, family, and community level interventions to promote healthy aging among Chinese older women. © The Author 2017.

Unintended consequences of cigarette price changes for alcohol drinking behaviors across age groups: evidence from pooled cross sections

PubMed Central

2012-01-01

Background Raising prices through taxation on tobacco and alcohol products is a common strategy to raise revenues and reduce consumption. However, taxation policies are product specific, focusing either on alcohol or tobacco products. Several studies document interactions between the price of cigarettes and general alcohol use and it is important to know whether increased cigarette prices are associated with varying alcohol drinking patterns among different population groups. To inform policymaking, this study investigates the association of state cigarette prices with smoking, and current, binge, and heavy drinking by age group. Methods The 2001-2006 Behavioral Risk Factor Surveillance System surveys (n = 1,323,758) were pooled and analyzed using multiple regression equations to estimate changes in smoking and drinking pattern response to an increase in cigarette price, among adults aged 18 and older. For each outcome, a multiple linear probability model was estimated which incorporated terms interacting state cigarette price with age group. State and year fixed effects were included to control for potential unobserved state-level characteristics that might influence smoking and drinking. Results Increases in state cigarette prices were associated with increases in current drinking among persons aged 65 and older, and binge and heavy drinking among persons aged 21-29. Reductions in smoking were found among persons aged 30-64, drinking among those aged 18-20, and binge drinking among those aged 65 and older. Conclusions Increases in state cigarette prices may increase or decrease smoking and harmful drinking behaviors differentially by age. Adults aged 21-29 and 65 and older are more prone to increased drinking as a result of increased cigarette prices. Researchers, practitioners, advocates, and policymakers should work together to understand and prepare for these unintended consequences of tobacco taxation policy. PMID:22784412

Major changes happened in the last decade in the HIV/AIDS pandemic. The disease is no longer limited to young age. Due to the effectiveness of HAART (Highly Active Anti-Retroviral Therapy) as well as new diagnosis in older age groups, many patients in AIDS centers are above 50 years of age. To determine the prevalence, demographics and clinical characteristics of newly diagnosed HIV/AIDS patients older than 50 years compared to younger newly diagnosed patients. Retrospective single center analysis of the demographics and clinical characterizations of 62 newly diagnosed HIV/AIDS patients over 50 years of age. The average age at diagnosis of the whole cohort was 39+/-16 years. There was a gradual increase in the age at diagnosis over the years, as well as the percent of patients above the age of 50 diagnosed with the disease. In comparison to younger patients, in the older group there were more males compared to females and less patients who acquired the HIV/AIDS in unprotected homosexual sex. Furthermore, CD4 cells counts were lower and viral load leveLs were higher at diagnosis in the older group. Despite good adherence, patients above the age of 50 don't achieve adequate immunological response and many are left with significant immunodeficiency (CD4<200). The prevaLence of patients above the age of 50 Living with HIV/AIDS in Israel is rising. Programs aimed at prevention, education and screening for this unique group are mandatory. An AIDS center should adopt new programs and routines to cope with the increasing number of patients over the age of 50 Living with HIV/AIDS.

Walking economy declines with increasing age, possibly leading to mobility limitation in older adults. Multicomponent fitness training could delay the decline in walking economy. This study aimed to determine the effect of multicomponent fitness training on walking economy in older adults. Participants were untrained adults, age 50 to 83 yr (N = 26, 10 males, age = 63 ± 6 yr, BMI = 25.6 ± 2.1 kg·m, mean ± SD). A control group was also recruited (N = 16, 9 males, age = 66 ± 10 yr, BMI = 25.4 ± 3.0 kg·m), matching the intervention group for age, weight, body composition, and fitness. The intervention group followed a multicomponent fitness program of 1 h, twice per week during 1 yr. The control group did not take part in any physical training. Fat-free mass, walking economy, and maximal oxygen uptake (V˙O2max) were measured in both groups before and after the year. Walking economy was measured with indirect calorimetry as the lowest energy needed to displace 1 kg of body mass for 1 m while walking on a treadmill. The data were compared between the two groups with repeated-measures ANOVA. Thirty-two subjects completed all measurements. There was an interaction between the effects of time and group on V˙O2max (P < 0.05) and walking economy (P < 0.05), whereas fat-free mass did not change significantly (P = 0.06). V˙O2max decreased by 1.8 mL·kg·min in the control group and increased by 1.3 mL·kg·min in the intervention group. The lowest energy needed to walk increased by 0.12 J·kg·m in the control group and decreased in the intervention group by 0.13 J·kg·m. Multicomponent fitness training decreases walking cost in older adults, preserving walking economy. Thus, training programs could delay mobility limitation with increasing age.

OBJECTIVE Aging increases the risk of developing impaired glucose tolerance (IGT) and type 2 diabetes. It has been proposed that increased reactive oxygen species (ROS) generation by dysfunctional mitochondria could play a role in the pathogenesis of these metabolic abnormalities. We examined whether aging per se (in subjects with normal glucose tolerance [NGT]) impairs mitochondrial function and how this relates to ROS generation, whether older subjects with IGT have a further worsening of mitochondrial function (lower ATP production and elevated ROS generation), and whether exercise reverses age-related changes in mitochondrial function. RESEARCH DESIGN AND METHODS Mitochondrial ATP and ROS production were measured in muscle from younger individuals with NGT, older individuals with NGT, and older individuals with IGT. Measurements were performed before and after 16 weeks of aerobic exercise. RESULTS ATP synthesis was lower in older subjects with NGT and older subjects with IGT versus younger subjects. Notably, mitochondria from older subjects (with NGT and IGT) displayed reduced ROS production versus the younger group. ATP and ROS production were similar between older groups. Exercise increased ATP synthesis in the three groups. Mitochondrial ROS production also increased after training. Proteomic analysis revealed downregulation of several electron transport chain proteins with aging, and this was reversed by exercise. CONCLUSIONS Old mitochondria from subjects with NGT and IGT display mitochondrial dysfunction as manifested by reduced ATP production but not with respect to increased ROS production. When adjusted to age, the development of IGT in elderly individuals does not involve changes in mitochondrial ATP and ROS production. Lastly, exercise reverses the mitochondrial phenotype (proteome and function) of old mitochondria. PMID:21677280

Ageing and exercise: building body capital in old age.

Research that provides better understanding of the motivational processes in older age to maintain a healthy and active lifestyle is sought after. We apply theoretical approaches to cultural capital, active and healthy aging health to shed light on the women's experiences in maintaining physical capabilities through an active lifestyle, and thereby facilitating their own inclusion in society. Thus, the aim of this paper is to explore why older home dwelling women over the age of 70 years or more spend time in physical exercise and their experiences about the importance of participating in group exercise for their daily life.This paper reports on a qualitative study based on interviews with 16 older women aged 70 years or more and regularly attending group exercise classes in the community at an established workout center. The data were analyzed the data using an inductive content analysis approach. Three overreaching and interrelated themes emerged from the interviews: "Building body capital for independence", "Building body capital to maintain vitality and being in control" and "Building resources for social interaction". The findings suggest that group exercise is important for building body capital. The group exercise helped the women in building bodily ability to manage everyday life, maintain vitality, being in control, pursue social interaction and live independently. These body resources were important for these older women's experience of the manageability and meaningfulness of daily life. This study has provided insights into older women's understanding and experiences of the challenges of everyday life within a theoretical framework of cultural capital and health. The women acquired cultural health capital, and more specifically body capital, by participating in the group exercise classes. The women's investment in body capital through regular physical activity created resources which facilitated social participation. Therefore professionals need to be aware of this when performing group exercise.

No evidence that 'fast-mapping' benefits novel learning in healthy Older adults.

Much evidence suggests that the Hippocampus is necessary for learning novel associations. Contrary to this, Sharon, Moscovitch, and Gilboa (2011) reported four amnesic patients with Hippocampal damage who maintained the capacity to learn novel object-name associations when trained with a 'fast-mapping' (FM) technique. This technique therefore potentially offers an alternative route for learning novel information in populations experiencing memory problems. We examined this potential in healthy ageing, by comparing 24 Older and 24 Young participants who completed a FM procedure very similar to Sharon et al. (2011). As expected, the Older group showed worse memory than the Young group under standard explicit encoding (EE) instructions. However, the Older group continued to show worse performance under the FM procedure, with no evidence that FM alleviated their memory deficit. Indeed, performance was worse for the FM than EE condition in both groups. Structural MRI scans confirmed reduced Hippocampal grey-matter volume in the Older group, which correlated with memory performance across both groups and both EE/FM conditions. We conclude FM does not help memory problems that occur with normal ageing, and discuss theoretical implications for memory theories. Copyright © 2014 The Authors. Published by Elsevier Ltd..

Adults with Down syndrome (DS) are often physically inactive, which may accelerate the onset of disease and aging symptoms. Eight older persons with DS (aged 54-61), and 10 younger persons with DS (aged 26-35) living in a residential care center were examined. Eighteen age- and gender-matched individuals without DS served as control groups.…

The objective of our study was to compare the microbiota diversity between two different age groups of Western European women. Skin-swab samples were collected directly on the forehead of 34 healthy Western European women: 17 younger (21-31 years old) and 17 older individuals (54-69 years old). Bacterial communities were evaluated using the 16S rRNA gene sequencing. Data revealed a higher alpha-diversity on the skin of older individuals compared to younger ones. Overall microbiota structure was different between the two age groups, as demonstrated by beta-diversity analysis, which also highlighted a high interpersonal variation within older individuals. Furthermore, taxonomic composition analysis showed both an increase of Proteobacteria and a decrease of Actinobacteria on the older skin. At the genus level, older skin exhibited a significant increase in Corynebacterium and a decrease in Propionibacterium relative abundance. Our study revealed a shift in the distribution of skin microbiota during chronological aging in Western European women. Altogether these results could become the basis to develop new approaches aiming to rebalance the skin microbiota, which is modified during the aging process. This article is protected by copyright.

The growing number of older prisoners in state and federal prisons has fostered an important discussion in literature regarding the potential benefits of age-segregated living arrangements for older inmates. This article begins with a brief review of the reasons for America's aging prison population. Thereafter, it uses a multidisciplinary literature review to clarify a 4-point rationale for age-segregated prisons: (a) cost savings via centralized health care for older prisoners; (b) the reduction of civil liabilities for correctional systems that centralize disability services as per requirements of the Americans with Disabilities Act of 1990; (c) the advancement of prisoner safety for older inmates; and (d) the promotion of rehabilitation by advancing treatment opportunities with a group that is most likely to desist from future criminal activity (in part) due to age-related desistance from crime. Conclusions focus on age segregation within the historical context of segregation in prison based on sociodemographic characteristics. PMID:28316366

The number of older adults in the criminal justice system is rapidly increasing. While this population is thought to experience an early onset of aging-related health conditions ("accelerated aging"), studies have not directly compared rates of geriatric conditions in this population to those found in the general population. The aims of this study were to compare the burden of geriatric conditions among older adults in jail to rates found in an age-matched nationally representative sample of community dwelling older adults. This cross sectional study compared 238 older jail inmates age 55 or older to 6871 older adults in the national Health and Retirement Study (HRS). We used an age-adjusted analysis, accounting for the difference in age distributions between the two groups, to compare sociodemographics, chronic conditions, and geriatric conditions (functional, sensory, and mobility impairment). A second age-adjusted analysis compared those in jail to HRS participants in the lowest quintile of wealth. All geriatric conditions were significantly more common in jail-based participants than in HRS participants overall and HRS participants in the lowest quintile of net worth. Jail-based participants (average age of 59) experienced four out of six geriatric conditions at rates similar to those found in HRS participants age 75 or older. Geriatric conditions are prevalent in older adults in jail at significantly younger ages than non-incarcerated older adults suggesting that geriatric assessment and geriatric-focused care are needed for older adults cycling through jail in their 50s and that correctional clinicians require knowledge about geriatric assessment and care.

To provide effective palliative care (PC) to the geriatric population, an understanding of the reasons for consultation, main diagnoses related to referral, and symptom severity in chronic disease states is essential. We compared the baseline characteristics, referral patterns, and symptom severity among older and younger patients referred for inpatient PC consultation. We conducted a retrospective review of 2382 inpatient PC consultations. We excluded "reconsultations" and patients under the age of 18. Patient characteristics (reason for consultation and diagnosis) and symptom severity were compared across three age groups: Younger, <65 years of age; Older, 65-84 years of age; and Oldest, 85 years of age and older. Multivariable logistic regression adjusted for the effects of gender, ethnicity, and diagnostic subset was performed. Most patients referred for inpatient PC consultation were older than the age of 65. Oldest patients were consulted on earlier and more often for "end-of-life care." Oldest adults were less likely to report pain, anxiety, and nausea (adjusted odds ratios [AOR] of 0.25, 0.39, and 0.19, respectively) and more likely to report anorexia than Younger adults (AOR=1.66). There was no clear difference between age groups in reporting of dyspnea and depression. Older adults in need of PC appear to have symptom burdens and consultation referral patterns that are different from those of younger patients. Further research is needed to determine whether these symptom patterns are caused by psychosocial factors, whether these reflect true differences among age groups, and whether symptom measurement instruments should be tailored to patient age.

Jecker, Nancy S

2018-06-01

How should healthcare systems prepare to care for growing numbers and proportions of older people? Older people generally suffer worse health than younger people do. Should societies take steps to reduce age-related health inequalities? Some express concern that doing so would increase age-related inequalities in healthcare. This paper addresses this debate by (1) presenting an argument in support of three principles for distributing scarce resources between age groups; (2) framing these principles of age group justice in terms of life stages; and (3) indicating policy implications that merit further attention in light of rapidly aging societies. © 2017 John Wiley & Sons Ltd.

Marital strain confers risk of cardiovascular disease (CVD), perhaps though cardiovascular reactivity (CVR) to stressful marital interactions. CVR to marital stressors may differ between middle-age and older adults, and types of marital interactions that evoke CVR may also differ across these age groups, as relationship contexts and stressors differ with age. We examined cardiovascular responses to a marital conflict discussion and collaborative problem solving in 300 middle-aged and older married couples. Marital conflict evoked greater increases in blood pressure, cardiac output and cardiac sympathetic activation than did collaboration. Older couples displayed smaller heart rate responses to conflict than did middle-aged couples, but larger blood pressure responses to collaboration–especially older men. These effects were maintained during a post-task recovery period. Women did not display greater CVR than men on any measure or in either interaction context, though they did display greater parasympathetic withdrawal. CVR to marital conflict could contribute to the association of marital strain with CVD for middle-aged and older men and women, but other age-related marital contexts (e.g., collaboration among older couples) may also contribute to this mechanism.

Given that self-perceptions of mental and physical health are important predictors of health outcomes and well-being, particularly among older adults, this study focuses on associations among age, alcohol consumption, and indicators of both self-rated mental health and self-rated physical health in a sample of sexual minority women (SMW). This study uses a community sample of SMW to examine the associations among age, drinking, and self-rated mental and physical health. Heavy drinking among older adult SMW (55+) was less prevalent than among young SMW, ages 18-25 and ages 26-39, but similar to rates reported among SMW ages 40-54. In addition, older SMW reported significantly higher levels of self-rated mental health, compared with SMW in the other age groups, but we found no significant associations between age and self-rated physical health. Across all age groups, moderate drinkers reported better self-rated physical health than alcohol abstainers. Overall, these results suggest that, among SMW, drinking does not decline as sharply with age as it does for heterosexual women in the general population. Given the current and projected increases in the aging population and the risks that heavy drinking presents for morbidity and mortality, interventions aimed at older SMW are needed.

Healthy ageing is a concept that concerns older persons' quality of life and is a key factor in promoting well-being. The older population in Thailand is growing. Isan (a region of north-eastern Thailand) has been reported as having one of the most rapidly increasing older populations in the country. In order to care for and promote the health of older people, healthcare providers should understand how healthy ageing is perceived by this target group. Although healthy ageing has been studied in different contexts as well as perspectives, no studies have previously focused on older persons' experiences of healthy ageing from a lifeworld perspective in Isan-Thai. Therefore, the aim of this study is to describe older persons' qualitatively different conceptions of healthy ageing in Isan-Thai culture. A phenomenographic approach with an epistemological base in lifeworld theory was used to disclose the various ways to conceptualize healthy ageing. Individual, qualitative interviews were conducted with 17 people aged 60 and above who live in Isan-Thai. The findings of this study revealed three categories of descriptions: "being independent in dependence," "being at peace," and "being a valuable person." This study also found family members, friends, healthcare providers, and religion important to healthy ageing in the Isan-Thai culture. Understanding how older people conceptualize healthy ageing is valuable for healthcare providers. They can apply these findings regarding healthy ageing in their fieldwork when caring for older people.

There is a lack of research investigating models of nursing care for older hospitalised patients that address the nursing needs of this group. The objective of this study is to evaluate the efficacy of models of care for acutely older patients tailored to two contexts: an aged care specific ward and a medical ward. This is a repeated measures design. Efficacy of the models was evaluated in terms of: patient and nurses' satisfaction with care provided; increased activities of daily living; reduced unplanned hospital readmissions; and medication knowledge. An aged care specific ward and a medical ward in two Sydney teaching hospitals. There were two groups of patients aged 65 years or older who were admitted to hospital for an acute illness: those admitted prior to model implementation (n=232) and those admitted during model implementation (n=116). Patients with moderate or severe dementia were excluded. The two groups of nurses were the pre-model group (n=90) who were working on the medical and aged care wards for the study prior to model implementation, and the post-model group (n=22), who were the nurses working on the wards during model implementation. Action research was used to develop the models of care in two wards: one for an aged care specific ward and another for a general medical ward where older patients were admitted. The models developed were based on empirical data gathered in an earlier phase of this study. The models were successful in both wards in terms of increasing satisfaction levels in patients and nurses (p<0.001), increasing functional independence as measured by activities of daily living (p<0.01), and increasing medication knowledge (p<0.001). Findings indicate that models of care developed by nurses using an evidence-based action research strategy can enhance both satisfaction and health outcomes in older patients.

Sports can protect dynamic visual acuity from aging: A study with young and older judo and karate martial arts athletes.

A major topic of current research in aging has been to investigate ways to promote healthy aging and neuroplasticity in order to counteract perceptual and cognitive declines. The aim of the present study was to investigate the benefits of intensive, sustained judo and karate martial arts training in young and older athletes and nonathletes of the same age for attenuating age-related dynamic visual acuity (DVA) decline. As a target, we used a moving stimulus similar to a Landolt ring that moved horizontally, vertically, or obliquely across the screen at three possible contrasts and three different speeds. The results indicated that (1) athletes had better DVA than nonathletes; (2) the older adult groups showed a larger oblique effect than the younger groups, regardless of whether or not they practiced a martial art; and (3) age modulated the results of sport under the high-speed condition: The DVA of young karate athletes was superior to that of nonathletes, while both judo and karate older athletes showed better DVA than did sedentary older adults. These findings suggest that in older adults, the practice of a martial art in general, rather than the practice of a particular type of martial art, is the crucial thing. We concluded that the sustained practice of a martial art such as judo or karate attenuates the decline of DVA, suggesting neuroplasticity in the aging human brain.

The proportion of people aged 65 or older is the fastest growing age group worldwide. Older adults in aged care facilities have higher levels of depression, and lower levels of social support and sense of belonging compared with older adults living in the community. Research has begun to assess the effectiveness of interventions to improve the mental health of residents and has found both cognitive and physical benefits of video game playing. The benefits of playing these games in a group may also lead to greater social interaction and decreased loneliness. The current study aims to investigate an intervention program designed to foster relationships among older adults in care based on shared interests. Residents will be assessed on the effectiveness of a 6 week program of playing Wii bowling in comparison to a control group. Participants will be allocated to the intervention (Wii bowling) or the control group based on their place of residence. Participants in the intervention group will be invited to participate in Wii bowling twice weekly, with up to three other residents for a period of 6 weeks. Residents in both conditions will be assessed for depression, social support, sense of belonging, and current self-rated mood at pre-intervention (0 weeks), post-intervention (6 weeks), and at 2-month follow up (14 weeks). Qualitative data on social interaction between group members will also be collected at weeks 1, 3, and 6. Both groups will receive a Wii console after week 6 to establish if residents and staff engage with the Wii without intervention. The Wii provides a user friendly platform for older adults to use video games, and it incorporates both social and competitive aspects in the game play. Existing research has not extensively investigated the social aspects of using this type of technology with older adults. If found to be effective, incorporating Wii games into an activity schedule may benefit the mental health of older adults living in care by establishing an intervention that is fun, economical, and easy to use.

Older adults are underrepresented in medical research for many reasons, including recruitment difficulties. Recruitment of older adults for research studies is often a time-consuming process and can be more challenging when the study involves older adults with unique exposures to traumatic events and from minority groups. The current article provides a brief overview of (a) challenges encountered while recruiting aging women Holocaust survivors for a case control study and (b) strategies used for meeting those challenges. The case group comprised women Holocaust survivors who were recently diagnosed with breast cancer and the control group comprised healthy women from a Holocaust-survivor community in Israel.

Postural control in certain situations depends on functioning of tactile or proprioceptive receptors and their respective dynamic integration. Loss of sensory functioning can lead to increased risk of falls in challenging postural tasks, especially in older adults. Stochastic resonance, a concept describing better function of systems with addition of optimal levels of noise, has shown to be beneficial for balance performance in certain populations and simple postural tasks. In this study, we tested the effects of aging and a tactile stochastic resonance stimulus (TSRS) on balance of adults in a sensory conflict task. Nineteen older (71-84 years of age) and younger participants (22-29 years of age) stood on a force plate for repeated trials of 20 s duration, while foot sole stimulation was either turned on or off, and the visual surrounding was sway-referenced. Balance performance was evaluated by computing an Equilibrium Score (ES) and anterior-posterior sway path length (APPlength). For postural control evaluation, strategy scores and approximate entropy (ApEn) were computed. Repeated-measures ANOVA, Wilcoxon signed-rank tests, and Mann-Whitney U-tests were conducted for statistical analysis. Our results showed that balance performance differed between older and younger adults as indicated by ES (p = 0.01) and APPlength (0.01), and addition of vibration only improved performance in the older group significantly (p = 0.012). Strategy scores differed between both age groups, whereas vibration only affected the older group (p = 0.025). Our results indicate that aging affects specific postural outcomes and that TSRS is beneficial for older adults in a visual sensory conflict task, but more research is needed to investigate the effectiveness in individuals with more severe balance problems, for example, due to neuropathy.

Abstract Introduction: Globally, increasing numbers of HIV-infected children are reaching adolescence due to antiretroviral therapy (ART). We investigated rates of loss-to-follow-up (LTFU) from HIV care services among children as they transition from childhood through adolescence. Methods: Individuals aged 5–19 years initiated on ART in a public-sector HIV clinic in Bulawayo, Zimbabwe, between 2005 and 2009 were included in a retrospective cohort study. Participants were categorized into narrow age-bands namely: 5–9 (children), 10–14 (young adolescents) and 15–19 (older adolescents). The effect of age at ART initiation, current age (using a time-updated Lexis expansion) and transitioning from one age group to the next on LTFU was estimated using Poisson regression. Results: Of 2273 participants, 1013, 875 and 385 initiated ART aged 5–9, 10–14 and 15–19 years, respectively. Unlike those starting ART as children, individuals starting ART as young adolescents had higher LTFU rates after moving to the older adolescent age-band (Adjusted rate ratio (ARR) 1.54; 95% CI: 0.94–2.55) and similarly, older adolescents had higher LTFU rates after transitioning to being young adults (ARR 1.79; 95% CI: 1.05–3.07). In older adolescents, the LTFU rate among those who started ART in that age-band was higher compared to the rate among those starting ART at a younger age (ARR = 1.70; 95% CI: 1.05, 2.77). This however did not hold true for other age-groups. Conclusions: Adolescents had higher rates of LTFU compared to other age-groups, with older adolescents at particularly high risk in all analyses. Age-updated analyses that examine movement across narrow age-bands are paramount in understanding how developmental heterogeneity in children affects HIV outcomes. PMID:28715158

Under most circumstances, the lifetime experience of sexual violence (SV) among girls and young women would likely increase with age. However, the empirical data from a retrospective study may not necessarily conform to this belief. Data from a nationally representative sample of females aged 13-24 years in Malawi in 2013 (n=1029) were analyzed. SV was defined as unwanted touching or attempted, pressured, or physically forced sex. The distribution of four types of SV among victims was compared between younger (13-18 years) and older (19-24 years) age groups. The strength of association between SV exposure and health outcomes was examined by age group. The risk of experiencing SV during their lifetime was three times greater for younger than that for older age females (Hazard ratio=3.32). Among females who had experienced SV, older age females were more likely to report forced or pressured sex (41.2%) as their initial SV experience than younger age females (17.8%). The strength of association between the SV exposure and health outcomes did not differ by age group. The self-report lifetime and childhood victimization to sexual violence may not necessarily higher among older than that among younger females. The current risk of exposure to sexual violence seems to influence the recall of lifetime and childhood victimization to a great extent. In order to make the field aware of this phenomenon, prevalence estimates from all three time frames (lifetime, childhood, and during the past 12 months) should be reported separately by age group.

The risk of liver cancer (LC) is regarded as age dependent. However, the influence of age on its prognosis is controversial. The aim of our study was to compare the long-term survival of younger versus older patients with LC. In this retrospective study, we searched Surveillance, Epidemiology, and End-RESULTS (SEER) population-based data and identified 27,255 patients diagnosed with LC between 1988 and 2003. These patients were categorized into younger (45 years and under) and older age (over 45 years of age) groups. Five-year cancer specific survival data was obtained. Kaplan-Meier methods and multivariable Cox regression models were used to analyze long-term survival outcomes and risk factors. There were significant differences between groups with regards to pathologic grading, histologic type, stage, and tumor size (p < 0.001). The 5-year liver cancer specific survival (LCSS) rates in the younger and older age groups were 14.5% and 8.4%, respectively (p < 0.001 by univariate and multivariate analysis). A stratified analysis of age on cancer survival showed only localized and regional stages to be validated as independent predictors, but not for advanced stages. Compared to older patients, younger patients with LC have a higher LCSS after surgery, despite the poorer biological behavior of this carcinoma.

Ground reaction forces and kinematics in distance running in older-aged men.

The biomechanics of distance running has not been studied before in older-aged runners but may be different than in younger-aged runners because of musculoskeletal degeneration at older age. This study aimed at determining whether the stance phase kinematics and ground reaction forces in running are different between younger- and older-aged men. Lower-extremity kinematics using three-dimensional motion analysis and ground reaction forces (GRF) using a force plate were assessed in 16 older-aged (55-65 yr) and 13 younger-aged (20-35 yr) well-trained male distance runners running at a self-selected (SRS) and a controlled (CRS) speed of 3.3 m.s-1. The older subjects ran at significantly lower self-selected speeds than the younger subjects (mean 3.34 vs 3.77 m.s-1). In both speed conditions, the older runners exhibited significantly more knee flexion at heel strike and significantly less knee flexion and extension range of motion. No age group differences were present in subtalar joint motion. Impact peak force (1.91 vs 1.70 BW) and maximal initial loading rate (107.5 vs 85.5 BW.s-1) were significantly higher in the older runners at the CRS. Maximal peak vertical and anteroposterior forces and impulses were significantly lower in the older runners at the SRS. The biomechanics of running is different between older- and younger-aged runners on several relevant parameters. The larger impact peak force and initial loading rate indicate a loss of shock-absorbing capacity in the older runners. This may increase their susceptibility to lower-extremity overuse injuries. Moreover, it emphasizes the focus on optimizing cushioning properties in the design and prescription of running shoes and suggests that older-aged runners should be cautious with running under conditions of high impact.

Stroop interference and negative priming (NP) suppression in normal aging.

Mayas, J; Fuentes, L J; Ballesteros, S

2012-01-01

Age-related differences in the reduction of Stroop interference were explored by comparing the performance of 18 younger (of mean age: 30.0±3.9 years) and 18 older healthy adults (of mean age: 75±7.2 years) in a color-word Stroop task. The aim of this study was to determine whether a decrease in the efficiency of inhibitory mechanisms associated with aging could account for age-related differences in the ability to suppress a pre-potent response. Participants performed a Stroop task to assess Stroop interference and NP suppression concurrently. Results showed a greater Stroop interference in older than in young adults. On the other hand, the NP effect was only reliable in the younger group, the older group not showing NP suppression. These findings suggest that the slowing hypothesis alone cannot explain this pattern of results and that the age-related differences must also involve an inhibitory breakdown during aging.

2015-12-01

Chronic low back pain (CLBP) is a highly prevalent and disabling musculoskeletal pain condition among older adults. Transcutaneous electrical nerve stimulation (TENS) is commonly used to treat CLBP, however response to TENS in older adults compared with younger adults is untested. In a dose-response study stratified by age, 60 participants with axial CLBP (20 young, 20 middle-aged, 20 older) received four 20-minute sessions of high-frequency high-intensity TENS over a 2- to 3-week period in a laboratory-controlled setting. Experimental measures of pain sensitivity (mechanical pressure pain detection threshold) and central pain excitability (phasic heat temporal summation and heat aftersensations) were assessed before and after TENS. Episodic or immediate axial CLBP relief was assessed after TENS via measures of resting pain, movement-evoked-pain, and self-reported disability. Cumulative or prolonged axial CLBP relief was assessed by comparing daily pain reports across sessions. Independent of age, individuals experienced episodic increase in the pressure pain detection threshold and reduction in aftersensation after TENS application. Similarly, all groups, on average, experienced episodic axial CLBP relief via improved resting pain, movement-evoked pain, and disability report. Under this design, no cumulative effect was observed as daily pain did not improve for any age group across the 4 sessions. However, older adults received higher TENS amplitude across all sessions to achieve TENS responses similar to those in younger adults. These findings suggest that older adults experience similar episodic axial CLBP relief to that of younger individuals after high-frequency, high-intensity TENS when higher dose parameters are used. This study examined age group differences in experimental and axial CLBP response to TENS, delivered under the current recommended parameters of strong, but tolerable amplitude. Older adults had comparable TENS response although at higher TENS amplitude than younger adults, which may have important mechanistic and clinical implications.

Background: The palatal masticatory mucosa is widely used as a donor material in periodontal plastic surgery. The thickness of graft tissue is an important factor for the graft survival. The purpose of this study was to determine the thickness of palatal mucosa by a bone sounding technique. The association of age and gender with the thickness of palatal mucosa was also examined. Materials and Methods: Twenty four healthy subjects had participated in the study. The younger age group of 16-30 years consisted of 12 subjects of 7 females and 5 males, and the older age group of 31-54 years consisted of 12 subjects, of 5 females and 7 males. A bone sounding method using a periodontal probe was done to assess the thickness of palatal mucosa at 15 measurement sites defined according to the gingival margin and palatal line. Mann-Whitney test was used to determine the difference in mucosal thickness between both the groups. Results: The younger age group had thinner mucosa ranged from 2 to 3.1 mm in thickness than the older age group which ranged from 3.2 to 3.7 mm. In the same age group, females had thinner mucosa than males in the same age group. The mean thickness of palatal masticatory mucosa ranged from 2.5 to 3.7 mm. Conclusion: The younger subjects had thinner mucosa than older subjects. The canine and premolar areas appeared to be the most appropriate donor site for grafting procedures. PMID:22628968

Does Age Affect the Relationship Between Pain and Disability? A Descriptive Study in Individuals Suffering From Chronic Low Back Pain.

Previous studies have revealed a weak to moderate relationship between pain and disability in individuals suffering from low back pain (LBP). However, to our knowledge, no studies have evaluated if this relationship is different between young and older adults. The objective of this descriptive, cross-sectional study was to determine whether the relationship between LBP intensity and physical disability is different between young and older adults. Pain intensity (measured with a visual analog scale) and physical disability scores (measured with the Oswestry Disability Index) were collected from the medical files of 164 patients with LBP. Separate Pearson correlation coefficients were calculated between these 2 variables for young (mean age 40 ± 6 years, n = 82) and older (62 ± 9 years, n = 82) individuals and a Fisher r-to-z transformation was used to test for group differences in the strength of the relationship. Linear regression analyses were also performed to determine whether the slope of the association was different between the 2 groups. A significant and positive association was found between pain intensity and disability for both young and older individuals. However, the correlation was stronger in the young group (r = 0.66; P < .01) than in the older group (r = 0.44; P < .01) (Fisher Z = 2.03; P < .05). The linear regression model also revealed that the slope of the relationship was steeper in the young group (P < .05). Although both young and older individuals showed a significant association between pain intensity and disability, the relationship between these 2 variables was more tenuous in older individuals than in young patients. Future research is essential to identify the factors underlying this age-related difference.

As the elderly population in the United States continues to grow, issues related to maintenance of health become increasingly important. Physical activity has positive benefits for healthy aging. Running, a popular form of exercise, is associated with the risk of developing injury, especially in older runners. Initial differences between older and younger runners have been observed, but these were observed without consideration of other differences between groups, such as running mileage. This study aims to compare running mechanics and lower-extremity coordination variability in matched groups of healthy younger and healthy older runners. Three-dimensional kinetics and kinematics were collected while 14 older adults (45-65 yr) and younger adults (18-35 yr) ran overground at 3.5 m·s. Knee, ankle, and hip joint angles and moments were determined. Discrete measures at foot strike (maximum and minimum) were determined and compared between groups. Segment angles during stance were utilized to calculate segment coordination variability between pelvis and thigh, thigh and shank, and shank and foot, using a modified vector coding technique. Knee and ankle joint angles were similar between groups (P > 0.05). Older runners had greater hip range of motion (P = 0.01) and peak hip flexion (P = 0.001) at a more extended hip position than younger runners. Older runners had smaller ankle plantarflexion moment (P = 0.04) and hip rotational moment (P = 0.005) than younger runners. There were no between-group differences in any of the variability measures (P > 0.05). Runners appear to maintain movement patterns and variability during running with increasing age, indicating that running itself may be contributing to maintenance of health among older runners in the current study.

Neurofeedback training improves attention and working memory performance.

The present study aimed to investigate the effectiveness of the frontal-midline theta (fmθ) activity uptraining protocol on attention and working memory performance of older and younger participants. Thirty-two participants were recruited. Participants within each age group were randomly assigned to either the neurofeedback training (fmθ uptraining) group or the sham-neurofeedback training group. There was a significant improvement in orienting scores in the older neurofeedback training group. In addition, there was a significant improvement in conflict scores in both the older and young neurofeedback training groups. However, alerting scores failed to increase. In addition, the fmθ training was found to improve working memory function in the older participants. The results further showed that fmθ training can modulate resting EEG for both neurofeedback groups. Our study demonstrated that fmθ uptraining improved attention and working memory performance and theta activity in the resting state for normal aging adults. In addition, younger participants also benefited from the present protocol in terms of improving their executive function. The current findings contribute to a better understanding of the mechanisms underlying neurofeedback training in cognitive function, and suggest that the fmθ uptraining protocol is an effective intervention program for cognitive aging.

A randomised controlled trial (RCT) was conducted to evaluate a three-hour face-to-face physical activity (PA) intervention in community-dwelling older German adults with four groups: The intervention group (IG) received behaviour change techniques (BCTs) based on the health action process approach plus a views-on-ageing component to increase PA. The second intervention group 'planning' (IGpl) contained the same BCTs, only substituted the views-on-ageing component against an additional planning task. An active control group received the same BCTs, however, targeting volunteering instead of PA. A passive control group (PCG) received no intervention. The RCT comprised 5 time-points over 14 months in N = 310 participants aged 64+. Self-reported as well as accelerometer-assessed PA. Neither PA measure increased in the IG as compared to the other groups at any point in time. Bayes analyses supported these null-effects. A possible explanation for this null-finding in line with a recent meta-analysis is that some self-regulatory BCTs may be ineffective or even negatively associated with PA in interventions for older adults as they are assumed to be less acceptable for older adults. This interpretation was supported by observed reluctance to participate in self-regulatory BCTs in the current study.

Limited data are available regarding the relationship between age and the effect of HMG-CoA reductase inhibitor (statin) treatment. The aim of the present analysis was to evaluate the relationships between age, baseline patient characteristics, and pravastatin treatment with respect to the development of cardiovascular disease (CVD) in the Management of Elevated Cholesterol in the Primary Prevention Group of Adult Japanese (MEGA) study, a large-scale clinical study conducted in Japanese patients with mild or moderate hyperlipidaemia to evaluate the primary preventive effect of pravastatin against coronary heart disease. To compare the prevalence of CVD risk factors, the incidence of CVD in relation to each risk factor, and final values and changes in lipid parameters, the 7832 patients were classified into six age groups: <45, 45-49, 50-54, 55-59, 60-64 and ≥65 years. The relationship between pravastatin (10-20 mg/day) treatment efficacy and aging and the incidence of events in relation to the age groups were compared using the multivariable Cox proportional hazards model. The prevalences of diabetes mellitus and hypertension were higher in older men than in younger men, while the prevalences of smoking and obesity were higher in younger men. However, a similar difference in risk factors was not seen in women. High-density lipoprotein cholesterol was higher in women than in men across all age groups. Triglycerides were higher in younger men than in older men and all groups of women. The mean follow-up levels of total cholesterol and low-density lipoprotein cholesterol were lower in older patients than in younger patients. Pravastatin (10-20 mg/day) reduced the risk of CVD by about 30-40% across all age groups, and there was no difference between men and women. Of particular note in this analysis, CVD risk was markedly reduced in older women compared with younger women (53% vs 30% in women aged ≥65 vs ≥45 years). A similar satisfactory risk reduction for CVD was achieved with low-dose pravastatin in all men and in older women in particular, despite differences in the prevalence of risk factors.

One challenge for gerontology is getting more students interested in aging at an earlier point in their academic career. This study evaluated the impact of an interdisciplinary course on aging designed for first-year undergraduate students. The course aimed to expand students’ appreciation of the personal and professional relevance of aging issues, with the goal of expanding their aging-related curricular and career interests. Main outcome variables of the study included knowledge of older adults and aging, attitudes toward older adults, and anxiety about personal aging. Participants included an intervention group enrolled in the course and a control group not enrolled in the course. Compared to baseline, at the end of the semester students in the class had more knowledge about aging and more positive explicit attitudes toward older adults, but their implicit attitudes toward older adults and anxiety about aging did not change. Control students showed no changes. These findings suggest that objective knowledge of aging and explicit attitudes improve with curricular intervention, but implicit attitudes and anxiety might be more difficult to change. Gerontology education is a complex undertaking whose diverse goals must be clearly articulated in order to guide curricular interventions and incite curiosity among young undergraduate students.

Disparity in disability between native-born non-Hispanic white and foreign-born Asian older adults in the United States: effects of educational attainment and age at immigration.

2011-04-01

It is widely known that educational attainment has considerable influence on the prevalence of disability among native-born non-Hispanic older adults in the US. However, few studies have examined whether educational attainment has a similar effect on disability among foreign-born Asian older adults. If it does not have a similar effect on these adults, why not, and is its effect influenced by the age at which they immigrated to the US? This study addresses these questions by using the 2006 American Community Survey Public Use Microdata Sample (ACS PUMS). Logistic regression analyses reveal that education has differential effects on the two racial groups. Education protects foreign-born Asians less than native-born non-Hispanic whites. In addition, Asian adults who immigrated earlier are less likely to experience disability. Interestingly, the interaction between age at immigration and educational attainment for foreign-born Asian older adults indicates that less educated Asians are more likely to benefit from early immigration. Heterogeneity within the Asian group is also examined. The findings suggest that educational attainment has differential effects not only on the two racial groups but also on the foreign-born Asian group depending on age at immigration.

Bridge employment (scheduled paid work after retirement age) may promote successful aging and continued health, as work can be an important component of daily physical activity. Appropriate work demands for older adults are neither well-established nor well-applied, however, and excessive loading or increased perceptions of discomfort may negate the health benefits of work activity. This study examined work status and musculoskeletal discomfort (MSD) amongst older Albertans. 1044 Albertans aged 55 years and older participating in an organized 'Games' received a research package. Enclosed in the package were an introductory letter, a return envelope, and modified versions of validated questionnaires examining leisure and work activities, activity frequency, and perceptions of musculoskeletal health. 228 respondents were classified into one of three employment trajectory groups: fully retired, fully employed, or bridge employed. Groups differed in age, and both employed groups more frequently reported MSDs in all body areas. Bridge employed reported increased 'occasional' frequency of musculoskeletal injury risk factors, while both groups reported similar overall ratings of work-related exertion. The increased MSDs reported by bridge employed adults may be the result of irregularity of work activity and soft tissue loading. Detailed examination of work demands and musculoskeletal injuries amongst bridge employed adults could help define safer levels for less regular work activity.

Gamma-butyric acid (GABA) dysfunction has been implicated in the pathophysiology of schizophrenia and its cognitive deficits. Proton magnetic resonance spectroscopy (MRS) was used to test the hypothesis that older participants with schizophrenia have lower anterior cingulate GABA levels compared with older control participants. One-hundred forty-five participants completed this study. For detection of GABA, spectra were acquired from the medial frontal/anterior cingulate cortex using a macromolecule-suppressed MEGA-PRESS sequence. Patients were evaluated for psychopathology and all participants completed neuropsychological tests of working memory, processing speed and functional capacity. GABA levels were significantly lower in the older participants with schizophrenia (n=31) compared with the older control (n=37) group (P=0.003) but not between the younger control (n=40) and schizophrenia (n=29) groups (P=0.994). Age strongly predicted GABA levels in the schizophrenia group accounting for 42% of the variance, but the effect of age was less in the control group accounting for 5.7% of the variance. GABA levels were specifically related to working memory but not processing speed performance, functional capacity, or positive or negative symptom severity. This is the largest MRS study of GABA in schizophrenia and the first to examine GABA without macromolecule contamination, a potentially significant issue in previous studies. GABA levels more rapidly declined with advancing age in the schizophrenia compared with the control group. Interventions targeted at halting the decline or increasing GABA levels may improve functional outcomes and quality of life as patients with schizophrenia age.

The aim of this retrospective study was to analyze differences in the initial hemodynamic assessment and its impact on the treatment in patients aged 80 years or older compared to younger patients during the first 6 h after admission to the medical intensive care unit (ICU). We analyzed 615 consecutive patients admitted to the medical ICU of which 124 (20%) were aged 80 years or more. The older group had a significantly higher acute physiology and chronic health evaluation (APACHE II) score, an overall mortality in the ICU and a presence of pre-existing cardiac disease. Both groups did not differ in the presence of shock and shock types on admission. In 57% of older and in 56% of younger patients, transthoracic echocardiography was performed with a higher therapeutic impact in the older patients. Transesophageal echocardiography was performed in 3% of the patients in both groups for specific diagnostic problems. Early reassessment with transthoracic echocardiography was necessary in 5% of the older and in 6% of the younger patients and resulted in a change of the treatment in one third of the patients. Continuous invasive hemodynamic monitoring was used in 11% of the older and in 10% of the younger patients and resulted in a therapeutic change in 71% of the older and in 64% of the younger patients. Patients aged 80 years or older represent 20% of all admissions to the medical ICU. Once admitted the older patients were similarly hemodynamically assessed as the younger ones with a similar impact on the treatment.

The authors evaluated the reliability and validity of a tool for measuring older adults’ decision-making competence (DMC). Two-hundred-five younger adults (25-45 years), 208 young-older adults (65-74 years), and 198 old-older adults (75-97 years) made judgments and decisions related to health, finance, and nutrition. Reliable indices of comprehension, dimension weighting, and cognitive reflection were developed. Unlike previous research, the authors were able to compare old-older with young-older adults’ performance. As hypothesized, old-older adults performed more poorly than young-older adults; both groups of older adults performed more poorly than younger adults. Hierarchical regression analyses showed that a large amount of variance in decision performance across age groups (including mean trends) could be accounted for by social variables, health measures, basic cognitive skills, attitudinal measures, and numeracy. Structural equation modeling revealed significant pathways from three exogenous latent factors (crystallized intelligence, other cognitive abilities, and age) to the endogenous DMC latent factor. Further research is needed to validate the meaning of performance on these tasks for real-life decision making. PMID:20545413

Obesity and a sedentary lifestyle are associated with physical impairments and biologic changes in older adults. Weight loss combined with exercise may reduce inflammation and improve physical functioning in overweight, sedentary, older adults. This study tested whether a weight loss program combined with moderate exercise could improve physical function in obese, older adult women. Participants (N = 34) were generally healthy, obese, older adult women (age range 55-79 years) with mild to moderate physical impairments (ie, functional limitations). Participants were randomly assigned to one of two groups for 24 weeks: (i) weight loss plus exercise (WL+E; n = 17; mean age = 63.7 years [4.5]) or (ii) educational control (n = 17; mean age = 63.7 [6.7]). In the WL+E group, participants attended a group-based weight management session plus three supervised exercise sessions within their community each week. During exercise sessions, participants engaged in brisk walking and lower-body resistance training of moderate intensity. Participants in the educational control group attended monthly health education lectures on topics relevant to older adults. Outcomes were: (i) body weight, (ii) walking speed (assessed by 400-meter walk test), (iii) the Short Physical Performance Battery (SPPB), and (iv) knee extension isokinetic strength. Participants randomized to the WL+E group lost significantly more weight than participants in the educational control group (5.95 [0.992] vs 0.23 [0.99] kg; P < 0.01). Additionally, the walking speed of participants in the WL+E group significantly increased compared with that of the control group (reduction in time on the 400-meter walk test = 44 seconds; P < 0.05). Scores on the SPPB improved in both the intervention and educational control groups from pre- to post-test (P < 0.05), with significant differences between groups (P = 0.02). Knee extension strength was maintained in both groups. Our findings suggest that a lifestyle-based weight loss program consisting of moderate caloric restriction plus moderate exercise can produce significant weight loss and improve physical function while maintaining muscle strength in obese, older adult women with mild to moderate physical impairments.

This study examined age-related differences between young and older adults in the involvement of verbal and visuo-spatial components of working memory (WM) when paths are learned from verbal and visuo-spatial inputs. A sample of 60 young adults (20-30 years old) and 58 older adults (60-75 years old) learned two paths from the person's point of view, one displayed in the form of a video showing the path, the other presenting the path in a verbal description. During the learning phase, participants concurrently performed a verbal task (articulatory suppression, AS group), or a visuo-spatial task (spatial tapping, ST group), or no secondary task (control, C group). After learning each path, participants completed tasks that involved the following: (1) recalling the sequential order and the location of landmarks; and (2) judging spatial sentences as true or false (verification test). The results showed that young adults outperformed older adults in all recall tasks. In both age groups performance in all types of task was worse in the AS and ST groups than in the C group, irrespective of the type of input. Overall, these findings suggest that verbal and visuo-spatial components of WM underpin the processing of environmental information in both young and older adults. The results are discussed in terms of age-related differences and according to the spatial cognition framework. © 2015 The British Psychological Society.

Few previous studies have directly compared crash rates of older and younger novice drivers. To inform discussion about whether Graduated Driver Licensing (GDL) policies that are applied in the US for younger novice drivers should be applied to older novice drivers, we conducted a longitudinal study to examine overall, nighttime, and multiple passenger crash rates over the initial four years of licensure differ for novice drivers licensed at different ages. Using data from the New Jersey Traffic Safety Outcomes (NJ-TSO) data warehouse, we selected all NJ drivers who obtained their initial intermediate driver's license from 2006 through 2014 and had at least one month of follow-up from the date of licensure to study end or death (n=1,034,835). Novice drivers were grouped based on age at licensure: age 17; 18-20; 21-24; and 25 or older. We estimated monthly rates for overall crashes (per 10,000 licensed drivers) as well as: late night crashes (11:01 p.m.-4:59 a.m.); early night crashes (9:00 p.m.-11:00 p.m.); and multiple passenger crashes (two or more passengers). Average monthly rates were calculated for specific relevant time periods and Poisson regression models were used to compare rates: (1) between novice driver groups with the same time since licensure; (2) over the first 48 months of licensure within each novice driver group; and (3) between same-aged 21-year-old drivers with varying lengths of licensure. Although initial (three months post-licensure) overall crash rates of novice NJ drivers age 21 and older were higher than rates of same-aged experienced drivers, they were substantially lower than initial rates for 17- to 20-year-old novice drivers, who are licensed under GDL policies. Moreover, older novice drivers experience much less steep crash reductions over the first year of licensure than younger novice drivers. Nighttime crash rates among the 21- to 24-year old and aged 25 and older novice driver groups were stable over the first year of licensure. For novice drivers under age 21, early night crash rates declined rapidly over the course of licensure, while changes in late night crashes were much smaller. First-year multiple passenger crash rates were highest for drivers licensed at age 18-20, and novice driver groups experienced varying amounts of reduction in multiple passenger crashes over time. Study findings support NJ's current GDL policies for 17- to 20-year-old novice drivers and the potential for added benefits from beginning the nighttime restriction at 9:00 p.m. Conversely, there was a lack of compelling evidence for additional policies for drivers licensed at age 21-24 and no evidence to indicate a need for additional GDL policies for NJ novices aged 25 years and older.

Age Differences in Self-Referencing: Evidence for Common and Distinct Encoding Strategies

2014-01-01

Although engagement of medial prefrontal cortex (MPFC) underlies self-referencing of information for younger and older adults, the region has not consistently been implicated across age groups for the encoding of self-referenced information. We sought to determine whether making judgments about others as well as the self influenced findings in the previous study. During an fMRI session, younger and older adults encoded adjectives using only a self-reference task. For items later remembered compared to those later forgotten, both age groups robustly recruited medial prefrontal cortex, indicating common neural regions support encoding across younger and older adults when participants make only self-reference judgments. Focal age differences emerged in regions related to emotional processing and cognitive control, though these differences are more limited than in tasks in which judgments also are made about others. We conclude that making judgments about another person differently affects the ways that younger and older adults make judgments about the self, with results of a follow-up behavioral study supporting this interpretation.

Aerobic exercise has been suggested to ameliorate aging-related decline in humans. Recently, evidence has indicated chronological aging is associated with decreases in measures of interhemispheric inhibition during unimanual movements, but that such decreases may be mitigated by long-term physical fitness. The present study investigated measures of ipsilateral (right) primary motor cortex activity during right-hand movements using functional magnetic resonance imaging and transcranial magnetic stimulation (TMS). Healthy, right-handed participant groups were comprised of 12 sedentary older adults, 12 physically active older adults, and 12 young adults. Active older adults and younger adults evidenced longer ipsilateral silent periods (iSP) and less positive BOLD of ipsilateral motor cortex (iM1) as compared to sedentary older adults. Across groups, duration of iSP from TMS was inversely correlated with BOLD activity in iM1 during unimanual movement. These findings suggest that increased physical activity may have a role in decreasing aging-related losses of interhemispheric inhibition. PMID:21440574

Aerodigestive tract foreign bodies in the older child and adolescent.

This study was undertaken in order to establish the incidence of aerodigestive tract foreign body accidents among older children and adolescents, and to investigate the circumstances surrounding these events. A review of patients treated over a 5-year period identified 367 children from whom aerodigestive tract foreign bodies were removed. Seventeen percent of these patients were 5 years of age or older. Among these children, 88% aspirated nonfood items, half of which were school supplies; 78% of the group 5 years old and under aspirated food items. Among older children with esophageal foreign bodies, 31% had food impactions, compared with 7% in the younger group; 70% of these children had a history of some anatomic abnormality of the esophagus. These data suggest that older children and adolescents represent a distinct group of patients at risk for foreign body accidents. Pediatricians and parents of children in this age group should discourage the practice of using the oral cavity as a repository for school supplies, and should stress the need for adequate preparation and mastication of food, particularly among children with esophageal abnormalities.

Nursing home residing older adults often experience fear of sickness or death, functional impairment and pain. It is difficult for these older adults to maintain a physically active lifestyle and to keep a positive outlook on life. This study evaluated the changes in quality of life, attitude to aging, assertiveness, physical fitness and body composition of nursing home residing elderly through a 15-week organized resistance training based physical activity program. Inactive older adults living in a state financed nursing home (N.=45) were randomly divided into two intervention groups and a control group. Both intervention groups were assigned to two physical activity sessions a week, but one of these groups also had weekly discussions on health and quality of life (Mental group). Data on anthropometric measures, fitness performance, as well as quality of life and attitudes to aging survey data were collected. Due to low attendance rate 12 subjects were excluded from the analyses. Statistical analysis included Paired Samples t-tests and Repeated Measures Analysis of Variance. Both intervention groups significantly improved their social participation, and their upper- and lower-body strength scores. Also, subjects in the Mental group showed improvement in agility fitness test and certain survey scales. No positive changes were detected in attitude towards aging and body composition measures in any groups. The post-hoc results suggest that Mental group improved significantly more than the Control group. Regular physical activity with discussions on health and quality of life made a more meaningful difference for the older adults living in nursing home than physical activity alone. Due to the fact that all participants were influenced by the program, it is suggested to further explore this area for better understanding of enhanced quality of life.

What Are Friends for? Friendships and Loneliness Over the Lifespan-From 18 to 79 Years.

Preventing and reducing loneliness is crucial to well-being and good health. Social relationships protect people against loneliness. Friendship qualities like intimacy and frequency of contact may vary throughout a person's lifespan. This study explores aspects of friendship and loneliness among people in different age groups: 18 to 29, 30 to 49, 50 to 64, and 65 to 79 years old. Data are from the Norwegian Life Course, Gender and Generations study (N = 14,725). Young people see their friends most often. The proportion of people without confidant friends is higher among older age groups. However, older age groups report higher levels of satisfaction with their contact with friends. Multivariate regression analyses show that the aspiration for contact with friends is more significant to loneliness than actual contact in all age groups. Dissatisfaction with contact with friends is strongly related to loneliness in all age groups. © The Author(s) 2016.

Age differences are not evident in pain-related stoicism and cautiousness in people with cancer pain. Little is known about the factors associated with these pain-related attitudes or age-related patterns in these associations. The present cross-sectional study investigated the biopsychosocial correlates of the attitudes in younger and older patients with advanced cancer. Pain-related stoicism (fortitude, concealment, superiority) and cautiousness (self-doubt, reluctance) were assessed using the Pain Attitudes Questionnaire-Revised (PAQ-R). Participants, 155 younger (younger than 60 years old) and 114 older (60 years old or older) patients with advanced cancer completed the PAQ-R and measures of sociodemographic and medical characteristics, pain intensity, cognitive-affective pain-related responses, physical functioning, psychological distress and well-being, and psychosocial functioning. Backwards regression analyses identified correlates for each PAQ-R factor separately for younger and older patients. Activity engagement was a frequent correlate, but its relationship with concealment was the only association common to both age groups. Younger and older patients exhibited different avoidance-related constructs suggesting relational challenges in the former group (avoidant attachment) and intrapersonal fear in the latter (cognitive avoidance). Medical correlates also showed age differences: younger patients showed symptom-focused correlates, whereas older patients showed aging-related correlates. Findings support a biopsychosocial framework of cancer-pain adaptation incorporating a lifespan-developmental perspective. To our knowledge, this article is the first to identify biopsychosocial correlates of stoic and cautious attitudes toward cancer pain in younger and older patients with advanced cancer. Findings highlight possible age-related motivations for greater pain-related stoicism or cautiousness and can potentially inform interventions addressing challenges in cancer-pain adaptation in advanced cancer.

The divide within: Older active ICT users position themselves against different 'Others'.

2015-12-01

Although research into older people's internet usage patterns is rapidly growing, their understandings of digital technologies, particularly in relation to how these are informed by their understandings of aging and old age, remain unexplored. This is the case because research on older active ICT users tends to regard old age as an empirically interesting part of the life-course as opposed to a theoretically profuse source of information about why and how older people engage with digital technologies. This article explores - through focus group interviews with 30 older adults (aged 66-89) - the ways in which the social position of old age is used by older active ICT users in order to make sense of how and why they engage with these technologies. In this article, positioning theory is used to shed light on how the older people interviewed positioned themselves as 'active older users' in the interviews. The analysis brings to the fore the divide that older people themselves create as they discursively position themselves against different types of ICT users and non-users (young and old) when describing how and why they engage with digital technologies.

Older adults often have problems finding their way in novel environments such as senior living residences and hospitals. The purpose of this study was to examine the types of self-reported search strategies and cues that older adults use to find their way in a virtual maze. Healthy, independently living older adults (n = 129) aged 55-96 were tested in a virtual maze task over a period of 3 days in which they had to repeatedly find their way to a specified goal. They were interviewed about their strategies on days 1 and 3. Content analysis was used to identify the strategies and cues described by the participants in order to find their way. Strategies and cues used were compared among groups. The participants reported the use of multiple spatial and non-spatial strategies, and some of the strategies differed among age groups and over time. The oldest age group was less likely to use strategies such as triangulation and distance strategies. All participants used visual landmarks to find their way, but the use of geometric cues (corners) was used less by the older participants. These findings add to the theoretical understanding of how older adults find their way in complex environments. The understanding of how wayfinding changes with age is essential in order to design more supportive environments. © The Author 2015.

Keep Up the Good Work! Age-Moderated Mediation Model on Intention to Retire

Dordoni, Paola; Van der Heijden, Beatrice; Peters, Pascale; Kraus-Hoogeveen, Sascha; Argentero, Piergiorgio

2017-01-01

In European nations, the aging of the workforce is a major issue which is increasingly addressed both in national and organizational policies in order to sustain older workers' employability and to encourage longer working lives. Particularly older workers' employability can be viewed an important issue as this has the potential to motivate them for their work and change their intention to retire. Based on lifespan development theories and Van der Heijden's ‘employability enhancement model’, this paper develops and tests an age-moderated mediation model (which refers to the processes that we want to test in this model), linking older workers' (55 years old and over) perceptions of job support for learning (job-related factor) and perceptions of negative age stereotypes on productivity (organizational factor), on the one hand, and their intention to retire, on the other hand, via their participation in employability enhancing activities, being the mediator in our model. A total of 2,082 workers aged 55 years and above were included in the analyses. Results revealed that the two proposed relationships between the predictors and intention to retire were mediated by participation in employability enhancing activities, reflecting two mechanisms through which work context affects intention to retire (namely ‘a gain spiral and a loss spiral’). Multi-Group SEM analyses, distinguishing between two age groups (55–60 and 61–65 years old), revealed different paths for the two distinguished groups of older workers. Employability mediated the relationship between perceptions of job support for learning and intention to retire in both age groups, whereas it only mediated the relationship between perceptions of negative age stereotypes and intention to retire in the 55–60 group. From our empirical study, we may conclude that employability is an important factor in the light of older workers' intention to retire. In order to motivate this category of workers to participate in employability enhancing activities and to work longer, negative age stereotypes need to be combated. In addition, creating job support for learning over the lifespan is also an important HR practice to be implemented in nowadays' working life. PMID:29089905

To examine differences in lower-extremity function in cognitive healthy older persons, older persons with mild cognitive impairment (MCI), and older persons with Alzheimer's disease (AD). Descriptive study. University Alzheimer's disease clinical and research program. Older persons (N=66) were studied (mean age, 76.7y); 22 were cognitively normal, 22 were diagnosed with probable MCI, 22 were diagnosed with probable AD. Not applicable. Lower-extremity function was assessed by the four-meter walk test (4MWT), Timed Up & Go (TUG) test, and sit-to-stand (STS) test. Analysis of variance, adjusting for covariates, revealed that performance on the 4MWT was significantly lower in the MCI and AD groups as compared with controls. TUG test performance was worse in the AD group compared with controls. No significant group differences were found for STS performance. These results suggest an association between cognitive impairment and lower-limb function in older persons. Walking speed could be evaluated for its possible utility in screening older persons at risk for cognitive impairment and falls. Copyright 2010 American Congress of Rehabilitation Medicine.

Understanding how vascular and metabolic factors impact on cognitive function is essential to develop efficient therapies to prevent and treat cognitive losses in older age. Cerebral metabolic rate of oxygen (CMRO2), cerebral blood flow (CBF) and venous oxygenation (Yv) comprise key physiologic processes that maintain optimum functioning of neural activity. Changes to these parameters across the lifespan may precede neurodegeneration and contribute to age-related cognitive decline. This study examined differences in blood flow and metabolism between 31 healthy younger (<50 years) and 29 healthy older (>50 years) adults; and investigated whether these parameters contribute to cognitive performance. Participants underwent a cognitive assessment and MRI scan. Grey matter CMRO2 was calculated from measures of CBF (phase contrast MRI), arterial and venous oxygenation (TRUST MRI) to assess group differences in physiological function and the contribution of these parameters to cognition. Performance on memory (p<0.001) and attention tasks (p<0.001) and total CBF were reduced (p<0.05), and Yv trended toward a decrease (p = .06) in the older group, while grey matter CBF and CMRO2 did not differ between the age groups. Attention was negatively associated with CBF when adjusted (p<0.05) in the older adults, but not in the younger group. There was no such relationship with memory. Neither cognitive measure was associated with oxygen metabolism or venous oxygenation in either age group. Findings indicated an age-related imbalance between oxygen delivery, consumption and demand, evidenced by a decreased supply of oxygen with unchanged metabolism resulting in increased oxygen extraction. CBF predicted attention when the age-effect was controlled, suggesting a task- specific CBF- cognition relationship.

Publicly reported hospital risk-standardized mortality rates (RSMRs) for acute myocardial infarction (AMI) are calculated for Medicare beneficiaries. Outcomes for older patients with AMI may not reflect general outcomes. To examine the relationship between hospital 30-day RSMRs for older patients (aged ≥65 years) and those for younger patients (aged 18 to 64 years) and all patients (aged ≥18 years) with AMI. Retrospective cohort study. 986 hospitals in the ACTION (Acute Coronary Treatment and Intervention Outcomes Network) Registry-Get With the Guidelines. Adults hospitalized for AMI from 1 October 2010 to 30 September 2014. Hospital 30-day RSMRs were calculated for older, younger, and all patients using an electronic health record measure of AMI mortality endorsed by the National Quality Forum. Hospitals were ranked by their 30-day RSMRs for these 3 age groups, and agreement in rankings was plotted. The correlation in hospital AMI achievement scores for each age group was also calculated using the Hospital Value-Based Purchasing (HVBP) Program method computed with the electronic health record measure. 267 763 and 276 031 AMI hospitalizations among older and younger patients, respectively, were identified. Median hospital 30-day RSMRs were 9.4%, 3.0%, and 6.2% for older, younger, and all patients, respectively. Most top- and bottom-performing hospitals for older patients were neither top nor bottom performers for younger patients. In contrast, most top and bottom performers for older patients were also top and bottom performers for all patients. Similarly, HVBP achievement scores for older patients correlated weakly with those for younger patients (R = 0.30) and strongly with those for all patients (R = 0.92). Minority of U.S. hospitals. Hospital mortality rankings for older patients with AMI inconsistently reflect rankings for younger patients. Incorporation of younger patients into assessment of hospital outcomes would permit further examination of the presence and effect of age-related quality differences. American College of Cardiology.

Speech comprehension abilities decline with age and with age-related hearing loss, but it is unclear how this decline expresses in terms of central neural mechanisms. The current study examined neural speech processing in a group of older adults (aged 56–77, n = 16, with varying degrees of sensorineural hearing loss), and compared them to a cohort of young adults (aged 22–31, n = 30, self-reported normal hearing). In a functional MRI experiment, listeners heard and repeated back degraded sentences (4-band vocoded, where the temporal envelope of the acoustic signal is preserved, while the spectral information is substantially degraded). Behaviorally, older adults adapted to degraded speech at the same rate as young listeners, although their overall comprehension of degraded speech was lower. Neurally, both older and young adults relied on the left anterior insula for degraded more than clear speech perception. However, anterior insula engagement in older adults was dependent on hearing acuity. Young adults additionally employed the anterior cingulate cortex (ACC). Interestingly, this age group × degradation interaction was driven by a reduced dynamic range in older adults who displayed elevated levels of ACC activity for both degraded and clear speech, consistent with a persistent upregulation in cognitive control irrespective of task difficulty. For correct speech comprehension, older adults relied on the middle frontal gyrus in addition to a core speech comprehension network recruited by younger adults suggestive of a compensatory mechanism. Taken together, the results indicate that older adults increasingly recruit cognitive control networks, even under optimal listening conditions, at the expense of these systems’ dynamic range.

Background Tranexamic acid effects in older people are difficult to predict. This study investigated the following research questions: 1) Is tranexamic acid effective in older patients undergoing primary total hip arthroplasty (THA)? and 2) Is there a difference in the effect of tranexamic acid between younger and older patients? Methods This was a 2-phase retrospective matched-pair study of patients who underwent THA in 2007–2013. All procedures were performed by surgeons with at least 10 years’ experience as senior consultant. In the first phase, 58 patients aged 65 years or more who received tranexamic acid were matched 1:1 with patients who did not receive tranexamic acid for age, sex, American Society of Anesthesiologists (ASA) classification and body mass index. In the second phase, 58 patients aged 65 years or more who received tranexamic acid were matched 1:1 with patients less than 65 years of age who received tranexamic acid for sex, ASA classification and body mass index. The primary outcome measures were percent maximum decrease in hemoglobin level and estimated blood loss after surgery. Results In the first phase, patients who received tranexamic acid conserved postoperative hemoglobin by a mean of 10.26 g/L (standard deviation [SD] 9.89 g/L) compared to the control group (p < 0.001). The mean difference in the estimated perioperative blood loss between the 2 groups was 410 mL (SD 376 mL) (p < 0.001), which indicated less bleeding in the treatment group. In the second phase, there was no difference between the younger (mean age 55.1 [SD 7.28] yr) and older (mean age 75.6 [SD 6.35] yr) groups in mean lowest postoperative hemoglobin level or percent decrease in hemoglobin level. Conclusion Tranexamic acid reduced the postoperative decrease in hemoglobin level and blood loss in older patients. Moreover, the significant hemoglobin-sparing effect of tranexamic acid in older patients was similar to that observed in younger patients. PMID:29806815

This study assessed the effects of balance/strength training on falls risk and posture in older individuals with type 2 diabetes. Sixteen individuals with type 2 diabetes and 21 age-matched control subjects (aged 50-75 years) participated. Postural stability and falls risk was assessed before and after a 6-week exercise program. Diabetic individuals had significantly higher falls risk score compared with control subjects. The diabetic group also exhibited evidence of mild-to-moderate neuropathy, slower reaction times, and increased postural sway. Following exercise, the diabetic group showed significant improvements in leg strength, faster reaction times, decreased sway, and, consequently, reduced falls risk. Older individuals with diabetes had impaired balance, slower reactions, and consequently a higher falls risk than age-matched control subjects. However, all these variables improved after resistance/balance training. Together these results demonstrate that structured exercise has wide-spread positive effects on physiological function for older individuals with type 2 diabetes.

In the eye of the beholder: Can counter-stereotypes change perceptions of older adults' social status?

PubMed

Robertson, Deirdre A; Weiss, David

2017-09-01

Negative age-related stereotypes often entail the perception that older adults have a lower social status than middle-aged adults. We hypothesized that older adults are perceived to have lower social status because they are less likely to be seen in prestigious occupational positions. People tend to infer general assumptions about group characteristics from exemplars. According to this, presenting a stereotype-inconsistent exemplar (i.e., older person in a high-status position) should change perceptions of older adults' social status. Study 1 (60 countries, N = 86,026, 18-99 years) showed that people in countries with an older relative to a younger political leader do not perceive as great a decline in social status from middle-aged to older adults. Study 2 (N = 131; 19-74 years) tested the causal link demonstrating that participants exposed to older exemplars holding a prestigious occupational position were significantly more likely to rate older adults as having a relative higher social status. We discuss implications for future interventions to change negative age-related stereotypes. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Older adult active retirement groups encompass health promotion, social and community psychological potential. However, little is known about the internal dynamics of these groups or their contribution to individual well-being and the community. This paper examines the Third Age Foundation as an example of one such group operating in a rural area in Ireland and explores the various relationships at work internally and externally. Methodology included: structured and semi-structured interviews, focus groups and a postal survey. A substantial contribution to members' well-being and community competence and cohesion was found. Findings are discussed in reference to the importance of individual and community empowerment, sustainability, social entrepreneurship/leadership and the potential of such models to support community-based living in older age.

Background Higher prevalence of multiple illnesses and cognitive impairment among older patients pose a risk of comprehension difficulties, potentially leading to medication errors. Therefore, the objective of this study was to investigate comprehension of discharge instructions among older patients admitted to a Quick Diagnostic Unit (QDU). Methods One hundred and two patients discharged from the QDU answered a questionnaire covering understanding of their hospitalization and discharge plan. Patients’ ability to recall discharge instructions and awareness of comprehension deficits, ie, ability to identify the misconceived information, were evaluated by comparing the questionnaires with the discharge letters. The population was divided into an older group (age ≥65 years) and a younger group. Results The older group (n=40) was less able to recall correct medication instructions when compared to the younger group (54% versus 78%, respectively; P=0.02). In multiple logistic regression analysis, correct recall of medication instructions was 4.2 times higher for the younger group compared to the older group (odds ratio 4.2, 95% confidence interval 1.5–11.9, P=0.007) when adjusted for sex and education. The older patients were less aware of their own comprehension deficits, and in respect to medication instructions awareness decreased 6.1% for each additional year of age (odds ratio 0.939, 95% confidence interval 0.904–0.98, P=0.001) when adjusted for sex and education. Conclusion Older patients were less able to recall correct medication instructions and less aware of their comprehension deficits after discharge from a QDU. The findings of the present study emphasize the importance of thorough communication and follow-up when treating older patients. PMID:24790423

In southeast Alaska the Chugach terrane represents an accretionary complex associated with several arcs active at 200-65 Ma. This lithostratigraphic unit consists of blueschists with Early Jurassic metamorphic ages and uncertain depositional ages; the Jurassic-Cretaceous McHugh Complex; and the Late Cretaceous Valdez Group. Detrital zircon ages from densely sampled transects reveals patterns in the assembly of the complex. Blueschists are almost totally barren of zircon, suggesting protoliths derived from mafic-intermediate volcanic protoliths far from a continental source. There is an age gap between the blueschists and the McHugh complex interpreted to be caused by an episode of tectonic erosion. The McHugh Complex is two separate units that are lithologically and geochronologically distinct. The older McHugh is a melange is dominated by stratally disrupted volcanic rocks, chert, and argillite. The oldest McHugh rocks have maximum depositional ages (MDA) of 177-150 Ma at Seldovia and 157-145 Ma at Turnagain Arm; the lack of older rocks at Turnagain Arm suggests removal of structural section by faulting. The MDAs of the older McHugh rocks do not decrease progressively away from the arc. There is a 45 m.y. gap in MDA between the older McHugh and the Late Cretaceous McHugh rocks. The younger McHugh rocks are dominated by volcanogenic sandstone and coarse conglomerate and MDA decreases from 100 Ma near the boundary with the older McHugh mesomelange to 85 Ma near the Valdez Group. The Valdez Group consists of coherently bedded turbidites with a MDA range of 85-60 Ma that decreases progressively outboard of the arc source. A sample from the Orca Group of the Prince William terrane is lithologically similar to the Valdez Group and there is no gap in MDA between Valdez and Orca Groups. 55 Ma dikes cut the McHugh and Valdez Groups in the western Chugach and Kenai Mountains. The oldest units of the Chugach terrane are the most deformed, with deformation and metamorphism becoming progressively less intense. The older part of the McHugh Complex was likely also subducted deeper than younger units but not beyond greenschist facies. Another period of tectonic erosion was initiated by ridge subduction at ~120 Ma, followed by continuous accretion the younger McHugh complex, the Valdez Group, and continued <60 Ma in the Orca Group.

To characterize the relationship between hydroxymethylglutaryl-CoA reductase inhibitors (statins) and outcomes in older persons with acute myocardial infarction (AMI). Observational study. Acute care hospitals in the United States from April 1998 to June 2001. Medicare patients aged 65 and older with a principal discharge diagnosis of AMI (N=65,020) who did and did not receive a discharge prescription for statins. The primary outcome of interest was all-cause mortality at 3 years after discharge. Of 23,013 patients with AMI assessed, 5,513 (24.0%) were receiving a statin at discharge. Nearly 40% of eligible patients (n=8,452) were aged 80 and older, of whom 1,310 (15.5%) were receiving a statin at discharge. In a multivariable model taking into account demographic, clinical, physician and hospital characteristics, and propensity score, discharge statin therapy was associated with significantly lower 3-year mortality (hazard ratio (HR)=0.89 (95% confidence interval (CI)=0.83-0.96)). In an analysis stratified by age, discharge statins were associated with lower mortality in patients younger than 80 (HR=0.84, 95% CI=0.76-0.92) but not in those aged 80 and older (HR=0.97, 95% CI=0.87-1.09). Statin therapy is associated with lower mortality in older patients with AMI younger than 80 but not in those aged 80 and older, as a group. This finding questions whether statin efficacy data in younger patients can be broadly applied to the very old and indicates the need for further study of this group.

Myofiber type grouping is a histological hallmark of age-related motor unit remodeling. Despite the accepted concept that denervation-reinnervation events lead to myofiber type grouping, the completeness of those conversions remains unknown. Type I myofiber grouping was assessed in vastus lateralis biopsies from Young (26 ± 4 years; n = 27) and Older (66 ± 4 years; n = 91) adults. Grouped and ungrouped type I myofibers were evaluated for phenotypic differences. Higher type I grouping in Older versus Young was driven by more myofibers per group (i.e., larger group size) (P < 0.05). In Older only, grouped type I myofibers displayed larger cross-sectional area, more myonuclei, lower capillary supply, and more sarco(endo)plasmic reticulum calcium ATPase I (SERCA I) expression (P < 0.05) than ungrouped type I myofibers. Grouped type I myofibers retain type II characteristics suggesting that conversion during denervation-reinnervation events is either progressive or incomplete.

With aging, the detrimental effects of stress can impair a person's ability to learn and sustain memory. Humor and its associated mirthful laughter can reduce stress by decreasing the hormone cortisol. Chronic release of cortisol can damage hippocampal neurons, leading to impairment of learning and memory. Objectives • The study intended to examine the effect of watching a humor video on short-term memory in older adults. Design • The research team designed a randomized, controlled trial. The study took place at Loma Linda University in Loma Linda, CA, USA. The study included 30 participants: 20 normal, healthy, older adults-11 males and 9 females-and 10 older adults with type 2 diabetes mellitus (T2DM)-6 males and 4 females. The study included 2 intervention groups of older adults who viewed humorous videos, a healthy group (humor group), aged 69.9 ± 3.7 y, and the diabetic group, aged 67.1 ± 3.8 y. Each participant selected 1 of 2 humorous videos that were 20 min in length, either a Red Skeleton comedy or a montage of America's Funniest Home Videos. The control group, aged 68.7 ± 5.5 y, did not watch a humor video and sat in quiescence. A standardized, neuropsychological, memory-assessment tool, the Rey Auditory Verbal Learning Test (RAVLT), was used to assess the following abilities: (1) learning, (2) recall, and (3) visual recognition. The testing occurred twice, once before (RAVLT1) and once after (RAVLT2) the humorous video for the humor and diabetic groups, and once before (RAVLT1) and once after (RAVLT2) the period of quiescence for the control group. At 5 time points, measurements of salivary cortisol were also obtained. The Kruskal-Wallis test was used to measure significance of the data based on the 3 groups. In the humor, diabetic, and control groups, (1) learning ability improved by 38.5%, 33.4%, and 24.0%, respectively (P = .025); (2) delayed recall improved by 43.6%, 48.1%, and 20.3%, respectively (P = .064); and (3) visual recognition increased by 12.6%, 16.7%, and 8.3%, respectively (P = .321). For levels of salivary cortisol, the research team found significant and borderline decreases for the humor group between baseline and (1) post-RAVLT1 (P = .047), (2) postvideo (P = .046), and (3) post-RAVLT2 (P = .062). The diabetic group showed significant decreases between baseline and (1) post-RAVLT1 (P = .047), (2) postvideo (P = .025), and (3) post-RAVLT2 (P = .034). The study found no significant changes for the control group. The research findings supported potential clinical and rehabilitative benefits for humor that can be applied to whole-person wellness programs for older adults. The cognitive components-learning ability and delayed recall-become more challenging as individuals age and are essential to older adults for providing a high quality of life: mind, body, and spirit. Because older adults can experience age-related memory deficits, complementary, enjoyable, and beneficial humor therapies should be implemented for them.

To study free- and protein-bound cobalamin absorption and the correlation with atrophic gastritis in healthy middle-aged and older subjects. A cross-sectional study. Fifty-two healthy subjects, aged 26 to 87 years, apparently free from conditions known to influence the cobalamin status. Middle-aged subjects were defined as those younger than 65 years of age (median age 57 years) and older subjects as those 65 years and older (median age 75 years). Protein-bound cobalamin absorption was assessed by 48-hour urinary excretion method following oral administration of scrambled egg yolk, labeled in vivo with 57 Co-cobalamin by injecting a hen with 57 Co-cyanocobalamin. The percentage of 57 Co-cobalamin bound to protein was 65%. Free cobalamin absorption was assessed by 48-hour urinary excretion method following oral administration of crystalline 57 Co-cyanocobalamin. Plasma cobalamin, folate and fasting plasma gastrin, and pepsinogen A and C concentrations were determined. The median urinary excretion of egg yolk 57 Co-cobalamin in middle-aged subjects was 12.3% (25th and 75th percentiles 10.5%-14.5%) compared with 11.7% (25th and 75th percentiles 9.8%-13.6%) in older subjects (P = .283). The median urinary excretion after administration of free 57 Co-cobalamin in middle-aged subjects was 25.7% (25th and 75th percentiles 20.6%-30.7%) compared with 27.9% (25th and 75th percentiles 21.4%-34.5%) in older subjects (P = .694). Neither egg yolk nor free 57 Co-cobalamin excretion correlated with age. A ratio of pepsinogen A to pepsinogen C less than 1.6, indicating atrophic gastritis, was found in 13 subjects. Within the atrophic gastritis group, 11 subjects had a pepsinogen A concentration greater than or equal to 17 micrograms/L, indicating mild to moderate atrophic gastritis, and two subjects had a pepsinogen A concentration less than 17 micrograms/L, indicating severe atrophic gastritis or gastric atrophy. All subjects had normal fasting plasma gastrin concentrations. Free and egg yolk 57 Co-cobalamin excretions were not reduced in the atrophic gastritis group when compared with the non-atrophic gastritis group. Median plasma cobalamin concentration was not significantly lower in older subjects (P = .205). Nonetheless, plasma cobalamin concentration correlated negatively with age (r = -.36; P = .008). We demonstrated no significant difference in either free or protein-bound cobalamin absorption between healthy middle-aged and older adults. In addition, no alteration in cobalamin absorption was found in subjects identified as having mild to moderate atrophic gastritis. Therefore, based on our results, the high prevalence of low cobalamin levels in older people cannot be explained by either the aging process or mild to moderate atrophic gastritis.

Crossing a two-way street is a complex task that involves visual, cognitive and motor abilities, all of which are known to decline with ageing. In particular, older pedestrians may experience difficulties when crossing two-way streets because of incorrect gap acceptance choices and impossible or unperceived evasive actions. To understand the overrepresentation of older pedestrians in crash statistics, several experimental studies have sought to identify traffic-related factors as well as those related to the abilities of the individuals themselves. However, none of these studies has required participants to actually walk across an experimental two-way street with curbs, which is a particularly challenging situation for older pedestrians. To fill this research gap, a quasi-experiment was conducted in a simulator including a total of 58 healthy aged participants (25 younger-old [age 60-72] and 33 older-old [age 72-92]) and 25 young adults (aged 18-25 years). Participants carried out a street-crossing task in a simulated two-way traffic environment; curbs were present on both sides of the experimental street. Participants also undertook a battery of tests to assess their visual and cognitive abilities. In addition, during the experiment, the participants' gait parameters were recorded. In line with earlier findings, the older-old group of participants made a higher number of decisions that led to collisions with approaching cars compared with the other groups. The two groups of older participants experienced specific difficulties when vehicles were in the far lane or when they approached rapidly. A regression analysis identified visual acuity, speed of processing (assessed using the UFOV(®) test), and step length as significant predictors of collisions. Our results have implications for understanding the difficulties experienced by older pedestrians and allow to draw up several recommendations for improving their safety.

Emotional Faces in Context: Age Differences in Recognition Accuracy and Scanning Patterns

2014-01-01

While age-related declines in facial expression recognition are well documented, previous research relied mostly on isolated faces devoid of context. We investigated the effects of context on age differences in recognition of facial emotions and in visual scanning patterns of emotional faces. While their eye movements were monitored, younger and older participants viewed facial expressions (i.e., anger, disgust) in contexts that were emotionally congruent, incongruent, or neutral to the facial expression to be identified. Both age groups had highest recognition rates of facial expressions in the congruent context, followed by the neutral context, and recognition rates in the incongruent context were worst. These context effects were more pronounced for older adults. Compared to younger adults, older adults exhibited a greater benefit from congruent contextual information, regardless of facial expression. Context also influenced the pattern of visual scanning characteristics of emotional faces in a similar manner across age groups. In addition, older adults initially attended more to context overall. Our data highlight the importance of considering the role of context in understanding emotion recognition in adulthood. PMID:23163713

The meaning of "aging in place" to older people.

This study illuminates the concept of "aging in place" in terms of functional, symbolic, and emotional attachments and meanings of homes, neighbourhoods, and communities. It investigates how older people understand the meaning of "aging in place," a term widely used in aging policy and research but underexplored with older people themselves. Older people (n = 121), ranging in age from 56 to 92 years, participated in focus groups and interviews in 2 case study communities of similar size in Aotearoa New Zealand, both with high ratings on deprivation indices. The question, "What is the ideal place to grow older?" was explored, including reflections on aging in place. Thematic and narrative analyses on the meaning of aging in place are presented in this paper. Older people want choices about where and how they age in place. "Aging in place" was seen as an advantage in terms of a sense of attachment or connection and feelings of security and familiarity in relation to both homes and communities. Aging in place related to a sense of identity both through independence and autonomy and through caring relationships and roles in the places people live. Aging in place operates in multiple interacting ways, which need to be taken into account in both policy and research. The meanings of aging in place for older people have pragmatic implications beyond internal "feel good" aspects and operate interactively far beyond the "home" or housing.

Irrational ideas. Older vs. younger inpatients.

The relationship to age of irrational beliefs among psychiatric inpatients has not been explored using the rational-emotive model. This study addressed the following two questions: 1) Do older and younger psychiatric inpatients differ in irrational beliefs? 2) Do older depressives differ from older nondepressives in irrational beliefs? Upon admission to a large medical center, 58 younger (less than 45 years old) and 54 older (greater than 55 years old) subjects were assessed on a battery of psychological tests, including the Idea Inventory and the Beck Depression Inventory. Results showed that older and younger inpatients did not differ on irrational beliefs. Results also showed that older and younger groups of depressives did not differ on the irrationality scores. When a correlational analysis was used, depression was related to irrationality within the older group but not within the younger group.

Most studies on juvenile homicide offenders (JHOs) have used small samples and have concentrated on adolescent male offenders. As a result, little is known about the population of female juveniles arrested for murder. This study utilized the Supplementary Homicide Report (SHR) database to investigate age differences between younger (aged 6-12 years) and older (aged 13-17 years) females arrested for murder in the United States from 1976 to 2007. As predicted, six variables used to test seven hypotheses with respect to younger and older female JHOs in single victim incidents were significant (victim age, victim gender, victim offender relationship, murder weapon, offender count, and homicide circumstance). Regression analysis revealed that younger girls were seven times more likely than older girls to kill children aged 0-12 years. Girls aged 6-12 years were five times more likely than their teen counterparts to be involved in conflict-related homicides as opposed to crime-related homicides. Although approximately the same percentages of younger and older girls killed infants under the age of 1, the victims were significantly different for the two offender age groups. This article concludes with a discussion of our findings and directions for future research. Copyright © 2014 John Wiley & Sons, Ltd.

Choice of Hemodialysis Access in Older Adults: A Cost-Effectiveness Analysis.

Although arteriovenous fistulas have been found to be the most cost-effective form of hemodialysis access, the relative benefits of placing an arteriovenous fistula versus an arteriovenous graft seem to be least certain for older adults and when placed preemptively. However, older adults' life expectancy is heterogeneous, and most patients do not undergo permanent access creation until after dialysis initiation. We evaluated cost-effectiveness of arteriovenous fistula placement after dialysis initiation in older adults as a function of age and life expectancy. Using a hypothetical cohort of patients on incident hemodialysis with central venous catheters, we constructed Markov models of three treatment options: ( 1 ) arteriovenous fistula placement, ( 2 ) arteriovenous graft placement, or ( 3 ) continued catheter use. Costs, utilities, and transitional probabilities were derived from existing literature. Probabilistic sensitivity analyses were performed by age group (65-69, 70-74, 75-79, 80-84, and 85-89 years old) and quartile of life expectancy. Costs, quality-adjusted life-months, and incremental cost-effectiveness ratios were evaluated for up to 5 years. The arteriovenous fistula option was cost effective compared with continued catheter use for all age and life expectancy groups, except for 85-89 year olds in the lowest life expectancy quartile. The arteriovenous fistula option was more cost effective than the arteriovenous graft option for all quartiles of life expectancy among the 65- to 69-year-old age group. For older age groups, differences in cost-effectiveness between the strategies were attenuated, and the arteriovenous fistula option tended to only be cost effective in patients with life expectancy >2 years. For groups for which the arteriovenous fistula option was not cost saving, the cost to gain one quality-adjusted life-month ranged from $2294 to $14,042. Among older adults, the cost-effectiveness of an arteriovenous fistula placed within the first month of dialysis diminishes with increasing age and lower life expectancy and is not the most cost-effective option for those with the most limited life expectancy.

2000-08-01

In older adults, clinical measures have been used to assess fall risk based on the ability to maintain stance or to complete a functional task. However, in an impending fall situation, a stepping response is often used when strategies to maintain stance are inadequate. We examined how maximal and rapid stepping performance might differ among healthy young, healthy older, and balance-impaired older adults, and how this stepping performance related to other measures of balance and fall risk. Young (Y; n = 12; mean age, 21 years), unimpaired older (UO; n = 12; mean age, 69 years), and balance-impaired older women IO; n = 10; mean age, 77 years) were tested in their ability to take a maximal step (Maximum Step Length or MSL) and in their ability to take rapid steps in three directions (front, side, and back), termed the Rapid Step Test (RST). Time to complete the RST and stepping errors occurring during the RST were noted. The IO group, compared with the Y and UO groups, demonstrated significantly poorer balance and higher fall risk, based on performance on tasks such as unipedal stance. Mean MSL was significantly higher (by 16%) in the Y than in the UO group and in the UO (by 30%) than in the IO group. Mean RST time was significantly faster in the Y group versus the UO group (by 24%) and in the UO group versus the IO group (by 15%). Mean RST errors tended to be higher in the UO than in the Y group, but were significantly higher only in the UO versus the IO group. Both MSL and RST time correlated strongly (0.5 to 0.8) with other measures of balance and fall risk including unipedal stance, tandem walk, leg strength, and the Activities-Specific Balance Confidence (ABC) scale. We found substantial declines in the ability of both unimpaired and balance-impaired older adults to step maximally and to step rapidly. Stepping performance is closely related to other measures of balance and fall risk and might be considered in future studies as a predictor of falls and fall-related injuries.

The population of adults accessing opioid treatment is growing older, but exact estimates vary widely, and little is known about the characteristics of the aging treatment population. Further, there has been little research regarding the epidemiology, healt h status, and functional impairments in this population. To determine the utilization of opioid treatment services by older adults in New York City. This study used administrative data from New York State licensed drug treatment programs to examine overall age trends and characteristics of older adults in opioid treatment programs in New York City from 1996 to 2012. We found significant increases in utilization of opioid treatment programs by older adults in New York City. By 2012, those aged 50-59 made up the largest age group in opioid treatment programs. Among older adults there were notable shifts in demographic background including gender and ethnicity, and an increase in self-reported impairments. More research is needed to fully understand the specific characteristics and needs of older adults with opioid dependence.

The relation between positive psychological well-being (PPWB) and sexual behaviour is understudied in older adult groups. To examine the relation between PPWB (positive affect and life satisfaction) and sexual behaviour (sexual activity and physical tenderness) in older adults, and whether it is independent from depressive symptoms and uniform across older age groups. Cross-sectional. Community-dwelling adults aged 65 years or older, Rotterdam, The Netherlands. Sexual behaviour, the Cantril Self-Anchoring Striving Scale, the Center for Epidemiological Studies Depression (CES-D) scale and partner status were assessed in 2,373 dementia-free older adults from the Rotterdam Study. For partnered participants, greater positive affect and life satisfaction was associated with more sexual activity and physical tenderness. Although CES-D was negatively associated with sexual behaviour within partnered older adults, there was no association between the negative affect sub-scale and sexual behaviour. The relations were independent of depressive symptoms, physical health and chronic disease status and were observed for both sexes at all older ages. For unpartnered participants, greater life satisfaction and was associated with more physical tenderness. There was low prevalence of sexual behaviour in unpartnered participants, limiting further stratification. Greater PPWB was associated with more sexual behaviour in partnered, community-dwelling older adults. We are the first to demonstrate that sexual behaviour is associated with PPWB, rather than lack of depressive symptoms; and that the association was present at all ages for partnered older adults. Limited conclusions can be drawn for unpartnered older adults as their sexual behaviour was infrequent. © The Author 2016.

Cognitive declines are common in older people and can be a major health issue in an aging world. One type of body-mind exercises, t'ai chi, can be a possible means to help maintaining older adults' cognitive abilities, in addition to beneficial effects of physical exercises. The purpose of this study was to investigate whether t'ai chi practitioners had better attention and memory functions than older people with or without regular exercises. A cross-sectional study examining the relationship between t'ai chi practice and age-, gender- and education-similar older peoples' attention and memory functions. Forty-two (42) community-dwelling elderly subjects, aged 60 or older, recruited from t'ai chi clubs in Hong Kong formed the t'ai chi group. Another 49 elderly having regular exercise habits were recruited from community centers for inclusion in the exercise group. A nonexercise group (normal healthy control) consisting of 44 subjects were also recruited by random selection and through contacting local elderly centers. They were also screened by the Modified Barthel Index, Chinese Mini-mental Status Examination, Geriatric Depression Scale, and evaluated by attention tests (Color Trail Form A-1 and 2) and memory tests (including Rivermead Behavioral Memory Test and The Hong Kong List Learning Test). The main finding was that the three groups differed in attention and memory functions, and the t'ai chi group had demonstrated better performance than the other two groups in most subtests. As a causal relationship cannot be assumed in the present cross-sectional study, future research is required to examine how t'ai chi can improve cognitive function using a randomized control trial as well as determining whether t'ai chi practice can lead to better health status among elderly people.

Background. Health-related quality of life (QOL) is an important outcome for older people who are often on dialysis for life. Little is, however, known about differences in QOL on haemodialysis (HD) and peritoneal dialysis (PD) in older age groups. Randomising patients to either modality to assess outcomes is not feasible. Methods. In this cross-sectional, multi-centred study we conducted QOL assessments (Short Form-12 Mental and Physical Component Summary scales, Hospital Anxiety and Depression Scale and Illness Intrusiveness Ratings Scale) in 140 people (aged 65 years or older) on PD and HD. Results. The groups were similar in age, gender, time on dialysis, ethnicity, Index of Deprivation (based on postcode), dialysis adequacy, cognitive function (Mini-Mental State Exam and Trail-Making Test B), nutritional status (Subjective Global Assessment) and social networks. There was a higher comorbidity score in the HD group. Regression analyses were undertaken to ascertain which variables significantly influence each QOL assessment. All were influenced by symptom count highlighting that the patient’s perception of their symptoms is a critical determinant of their mental and physical well being. Modality was found to be an independent predictor of illness intrusion with greater intrusion felt in those on HD. Conclusions. Overall, in two closely matched demographic groups of older dialysis patients, QOL was similar, if not better, in those on PD. This study strongly supports offering PD to all suitable older people.

Psychomotor slowing has been documented in depression. The digital Clock Drawing Test (dCDT) provides: (i) a novel technique to assess both cognitive and motor aspects of psychomotor speed within the same task and (ii) the potential to uncover subtleties of behavior not previously detected with non-digitized modes of data collection. Using digitized pen technology in 106 participants grouped by Age (younger/older) and Affect (euthymic/unmedicated depressed), we recorded cognitive and motor output by capturing how the clock is drawn rather than focusing on the final product. We divided time to completion (TTC) for Command and Copy conditions of the dCDT into metrics of percent of drawing (%Ink) versus non-drawing (%Think) time. We also obtained composite Z-scores of cognition, including attention/information processing (AIP), to explore associations of %Ink and %Think times to cognitive and motor performance. Despite equivalent TTC, %Ink and %Think Command times (Copy n.s.) were significant (AgeXAffect interaction: p=.03)-younger depressed spent a smaller proportion of time drawing relative to thinking compared to the older depressed group. Command %Think time negatively correlated with AIP in the older depressed group (r=-.46; p=.02). Copy %Think time negatively correlated with AIP in the younger depressed (r=-.47; p=.03) and older euthymic groups (r=-.51; p=.01). The dCDT differentiated aspects of psychomotor slowing in depression regardless of age, while dCDT/cognitive associates for younger adults with depression mimicked patterns of older euthymics.

Abstract Little is known on the relationship between herpes zoster and Parkinson's disease in older people. This study aimed to explore whether herpes zoster could be associated with Parkinson's disease in older people in Taiwan. We conducted a retrospective cohort study using the claim data of the Taiwan National Health Insurance Program. There were 10,296 subjects aged 65 years and older with newly diagnosed herpes zoster as the herpes zoster group and 39,405 randomly selected subjects aged 65 years and older without a diagnosis of herpes zoster as the nonherpes zoster group from 1998 to 2010. Both groups were followed up until subjects received a diagnosis of Parkinson's disease. This follow-up design would explore whether subjects with herpes zoster were at an increased risk of Parkinson's disease. Relative risks were estimated by adjusted hazard ratio (HR) and 95% confidence interval (CI) using the multivariable Cox proportional hazards regression model. The incidence of Parkinson's disease was higher in the herpes zoster group than that in the nonherpes zoster group (4.86 vs 4.00 per 1000 person-years, 95% CI 1.14, 1.29). After adjustment for confounding factors, the multivariable Cox proportional hazards regression model revealed that the adjusted HR of Parkinson's disease was 1.17 for the herpes zoster group (95% CI 1.10, 1.25), compared with the nonherpes zoster group. Older people with herpes zoster confer a slightly increased hazard of developing Parkinson's disease when compared to those without herpes zoster. We think that herpes zoster correlates with increased risk of Parkinson's disease in older people. When older people with herpes zoster seek help, clinicians should pay more attention to the development of the cardinal symptoms of Parkinson's disease. PMID:28207515

In old age, social groups can be a crucial component for health and well-being. In 2009-2010, a follow-up survey was carried out in Florianópolis, Brazil to understand the impact of a variety of programs established since 2002 that were designed to enhance social activities among the older adult population. This study employed two surveys within the population of older adults in Florianópolis. The first survey interviewed a total of 875 older adults in 2002, and the second survey involved 1,705 older adults between 2009 and 2010. By 2010, many new programs were offered in the community and the enrollment of older adults in social programs followed similar trends. "Convivência" groups stood out as extremely popular social groups among this population. This paper discusses some of the potential outcomes associated with participation in "convivência" groups.

Franz, G A

To provide a cigarette price elasticity reference for adult age groups, and to estimate the smoking behaviour changes in US adults in light of unprecedented state excise tax increases on cigarettes during the 1990s. Individual-level data from the Behavioral Risk Factor Surveillance System for 1993-2000 were merged with state-level cigarette price and tax data. Data were analysed for different age groups using a weighted least squares regression framework. The outcome variables measured were whether an individual was a smoker, whether he/she had tried to quit smoking during the previous year, and how many cigarettes were smoked per day among the total population and among active smokers. This study confirmed previous results that younger individuals are more responsive to price changes than older individuals. Although older age groups are less sensitive to price changes, their smoking behaviour changes are still statistically significant. This study found that while older individuals are less responsive to price changes than younger individuals, their behavioural changes due to cigarette price increases should not be ignored.

J Strength Cond Res 31(5): 1290-1296, 2017-The purpose of this study was to quantify the physical demands of representative adolescent rugby union match-play and investigate the difference between playing positions and age groups. Players (n = 112) were classified into 6 groups by playing position (forwards and backs) and age group (U16, U18, and U20). The physical demands were measured using microsensor-based technology and analyzed using magnitude-based inferences to assess practical importance. Backs had a greater relative distance (except U16s) and a greater high-speed running distance per minute than forwards, with the magnitude of difference between the positions becoming larger in older age groups. Forwards had higher values of PlayerLoad (PL) per minute (accumulated accelerations from the 3 axes of movement) and PL slow per minute (accumulated accelerations from the 3 axes of movement where velocity is <2 m·s) than backs at all age groups. Relative distance, low-, and high-speed running per minute all had a trend to be lower in older age groups for both positions. PlayerLoad per minute was greater in U18 than that in U16 and U20 for both positions. PlayerLoad slow per minute was greater for older age groups besides the U18 and U20 comparisons, which were unclear. The contrasts in physical demands experienced by different positions reinforce the need for greater exposure to sprinting and collision-based activity for backs and forwards, respectively. Given PL metrics peak at U18 and locomotor demands seem to be lower in older ages, the demands of representative adolescent rugby union do not seem to be greater at U20 as expected.

To investigate how 3 measures of health literacy correlate with age and the explanatory roles of fluid and crystallised cognitive abilities in these relationships among older adults. Cross-sectional baseline analysis of the 'LitCog' cohort study. 1 academic internal medicine clinic and 5 federally qualified health centres in Chicago, USA. English-speaking adults (n=828) aged 55-74 years, recruited from August 2008 through October 2011. Health literacy was measured by the Test of Functional Health Literacy in Adults (TOFHLA) and the Newest Vital Sign (NVS), both of which assess reading comprehension and numeracy in health contexts, and by the Rapid Estimate of Adult Literacy in Medicine (REALM), which assesses medical vocabulary. Fluid cognitive ability was assessed through the cognitive domains of processing speed, inductive reasoning, and working, prospective and long-term memories, and crystallised cognitive ability through the verbal ability domain. TOFHLA and NVS scores were lower at ages 70-74 years compared with all other age groups (p<0.05 for both tests). The inverse association between age and TOFHLA score was attenuated from β=-0.39 (95% CI -0.55 to -0.22) to β=-0.06 (95% CI -0.20 to 0.08) for ages 70-74 vs 55-59 years when fluid cognitive ability was added to the model (85% attenuation). Similar results were seen with NVS scores (68% attenuation). REALM scores did not differ by age group (p=0.971). Crystallised cognitive ability was stable across age groups, and did not influence the relationships between age and TOFHLA or NVS performance. Health literacy skills show differential patterns of age-related change, which may be explained by cognitive ageing. Researchers should select health literacy tests appropriate for their purposes when assessing the health literacy of older adults. Clinicians should be aware of this issue to ensure that health self-management tasks for older patients have appropriate cognitive and literacy demands. Published by the BMJ Publishing Group Limited.

In two experiments, we investigated the ability of younger and older observers to perceive and discriminate 3-D shape from static and dynamic patterns of binocular disparity. In both experiments, the younger observers' discrimination accuracies were 20% higher than those of the older observers. Despite this quantitative difference, in all other respects the older observers performed similarly to the younger observers. Both age groups were similarly affected by changes in the magnitude of binocular disparity, by reductions in binocular correspondence, and by increases in the speed of stereoscopic motion. In addition, observers in both age groups exhibited an advantage in performance for dynamic stereograms when the patterns of binocular disparity contained significant amounts of correspondence "noise." The process of aging does affect stereopsis, but the effects are quantitative rather than qualitative.

to examine perceived age discrimination in a large representative sample of older adults in England. this cross-sectional study of over 7,500 individuals used data from the fifth wave of the English Longitudinal Study of Ageing (ELSA), a longitudinal cohort study of men and women aged 52 years and older in England. Wave 5 asked respondents about the frequency of five everyday discriminatory situations. Participants who attributed any experiences of discrimination to their age were treated as cases of perceived age discrimination. Multivariable logistic regression analysis was used to estimate the odds ratios of experiencing perceived age discrimination in relation to selected sociodemographic factors. approximately a third (33.3%) of all respondents experienced age discrimination, rising to 36.8% in those aged 65 and over. Perceived age discrimination was associated with older age, higher education, lower levels of household wealth and being retired or not in employment. The correlates of age discrimination across the five discriminatory situations were similar. understanding age discrimination is vital if we are to develop appropriate policies and to target future interventions effectively. These findings highlight the scale of the challenge of age discrimination for older adults in England and illustrate that those groups are particularly vulnerable to this form of discrimination.

Older women are one of the most inactive groups in the population despite being at an age where they are at greater risk of health problems. Knowing what influences these women to exercise regularly may help the development of strategies to assist sedentary women in this age group to become active. This paper reports the findings of a study that explored why a group of older women attending a fitness centre participate in regular exercise activities. The study used a qualitative approach to data collection and analysis. Data were collected using in-depth interviews from ten women over 50 years of age who exercised on a regular basis. The findings revealed four themes relating to the maintenance of general wellbeing: exercise as a socially supportive activity, exercising to maintain wellbeing, exercising to maintain independence, and exercise as liberating. The implications of the findings for nursing education, clinical practice and research are discussed.

Phobias are common in later life, yet treatment research in this population remains scant. The efficacy of exposure therapy, in combination with other Cognitive-Behavioral Therapy (CBT) components, in the treatment of specific phobia with a middle and older aged sample was examined. Sixteen adults aged 45–68 with DSM-IV diagnosis of a specific phobia received a manualized intervention over ten weeks, and were compared with a control group. Results indicated significant time effects in the treatment group for the primary outcome variables of phobic severity and avoidance as well as secondary outcome variables including depression and anxiety. Symptom presence and severity also significantly declined in the treatment group. No significant changes in state anxiety were noted across the treatment period. Such results provide support for the efficacy of exposure combined with CBT treatment for specific phobia in middle to older aged adults. PMID:18044196

Empathy is essential for successful social interactions and relationships. The neural underpinnings of empathy have predominantly been studied in the young adult population, thus little is known about how they evolve across the life span. In the present study, we used functional magnetic resonance imaging to investigate age-related differences in brain activity associated to empathy for positive and negative emotions. Female participants of 3 age groups-adolescents, young, and older adults-underwent an experimental paradigm inducing both first-hand and empathic experience of pleasant and unpleasant touch. Group comparisons and regression analyses revealed that older adults showed lower activation within the anterior insula with respect to young adults, during both empathy conditions. Further analyses provided evidence that years of education, theory of mind ability, gray matter volume, and first-hand affect processing did not account for these effects. These findings indicate that the neural bases of empathy change across different age groups, from adolescence to old age. Different ages and in particular older age seem to significantly influence the way in which we represent and share others' positive and negative emotions. Copyright © 2017 Elsevier Inc.

Population aging and global warming generate important public health risks, as older adults have increased susceptibility to heat stress (SHS). We defined and validated sex-specific screening criteria for SHS during work and leisure activities in hot environments in individuals aged 31-70 years using age, anthropometry, and cardiorespiratory fitness. A total of 123 males and 44 females [44 ± 14 years; 22.9 ± 7.4% body fat; 40.3 ± 8.6 peak oxygen uptake (mlO 2 /kg/min)] participated, separated into the Analysis (n = 111) and Validation (n = 56) groups. Within these groups, participants were categorized into YOUNG (19-30 years; n = 47) and OLDER (31-70 years; n = 120). All participants performed exercise in the heat inside a direct calorimeter. Screening criteria for OLDER participants were defined from the Analysis group and were cross-validated in the Validation group. Results showed that 30% of OLDER individuals in the Analysis group were screened as SHS positive. A total of 274 statistically valid (p < 0.05) criteria were identified suggesting that OLDER participants were at risk for SHS when demonstrating two or more of the following (males/females): age ≥ 53.0/55.8 years; body mass index ≥29.5/25.7 kg/m 2 ; body fat percentage ≥ 28.8/34.9; body surface area ≤2.0/1.7 m 2 ; peak oxygen uptake ≤48.3/41.4 mlO 2 /kg fat free mass/min. In the Validation group, McNemar χ 2 comparisons confirmed acceptable validity for the developed criteria. We conclude that the developed criteria can effectively screen individuals 31-70 years who are at risk for SHS during work and leisure activities in hot environments and can provide simple and effective means to mitigate the public health risks caused by heat exposure.

Utilizing relevance theory, this study investigated the ability of children with Asperger syndrome (AS) and high-functioning autism (HFA) to use context when answering questions and when giving explanations for their correct answers. Three groups participated in this study: younger AS/HFA group (age 7-9, n=16), older AS/HFA group (age 10-12, n=23) and a normally functioning control group (age 7-9, n=23). The results indicated that the younger AS/HFA group did less well when answering contextually demanding questions compared to the control group, and the performance of the older AS/HFA group fell in between the younger AS/HFA group and the control group. Both AS/HFA groups had difficulties explaining their correct answers, suggesting that they are not always aware of how they have derived answers from the context.

Older patients with burn injury have a greater likelihood for discharge to nursing facilities. Recent research indicates that older patients discharged to nursing facilities are two to three times as likely to die within a 3-year period relative to those discharged to home. In light of these poor long-term outcomes, we conducted this study to identify predictors for discharge to independent vs nonindependent living status in older patients hospitalized for burns. We retrospectively reviewed all older adults (age ≥ 55 years) who were prospectively enrolled in a longitudinal multicenter study of outcomes from 1993 to 2011. Patient, injury, and treatment outcomes data were analyzed. Recognizing that transfer to inpatient rehabilitation may have impacted final hospital discharge disposition: we assessed the likelihood of inpatient rehabilitation stay, based on identified predictors of inpatient rehabilitation. We subsequently performed a logistic regression analysis on the clustered, propensity-matched cohort to assess associations of burn and injury characteristics on the primary outcome of final discharge status. A total of 591 patients aged ≥55 years were treated and discharged alive from three participating U.S. burn centers during the study period. Mean burn size was 14.8% (SD 11.2%) and mean age was 66.7 years (SD 9.3 years). Ninety-three patients had an inpatient rehabilitation stay before discharge (15.7%). Significant factors predictive of inpatient rehabilitation included a burn >20% TBSA, mechanical ventilation, older age, range of motion deficits at acute care discharge, and study site. These factors were included in the propensity model. Four hundred seventy-one patients (80%) were discharged to independent living status. By matched propensity analysis, older age was significantly associated with a higher likelihood of discharge to nonindependent living (P < .01 in both the 65-74 age group and the oldest age group when compared with the 55-64 age group). Comorbidity (P < .01) and history of alcohol abuse (P < 0.01) were also predictive patient factors. Furthermore, clinical practice variations among the three study sites also constituted a significant factor in discharge disposition (both P < .01 when compared with the index study site). Older age remains an important risk factor for discharge to nonindependent living status, even after accounting for inpatient rehabilitation stay. This analysis, however, reveals significant variations in discharge disposition practices among the three participating study sites. We believe that these variations among burn centers need to be elucidated to better understand discharge disposition status in older patients with burns.

To investigate differences in sexual risk factors between adolescent girls reporting similar-aged or older sex partners. Adolescent girls are at significant risk of heterosexual-acquired HIV infection and other long-term reproductive health issues. Sexual partner age discordance in teen girls has been correlated with STIs, lack of protection, multiple partners and earlier age of sexual transition. A descriptive study comparing girls currently involved with age-discordant partners to those with similar-aged partners. Two-sample t-test for continuous variables and chi-squared test or Fisher's exact test for categorical variables were used to compare groups. Baseline data from 738 sexually active, urban, adolescent girls aged 15-19 were analysed to determine which behaviours were more likely to occur in girls with older partners. Data were collected as part of a gender-specific HIV-prevention intervention in a randomised controlled trial (RCT) tailored to adolescent girls. Multiple reported sexual risk behaviours were found to significantly differ between the two groups at baseline. Overall, girls with older partners had more episodes of sexual instances (vaginal, anal and oral). Specific sexual risk behaviours were found to be statistically significant between the two groups. Girls with older partners started having sex at earlier ages, had more lifetime sexual partners, higher incidents of STIs and were reluctant to discuss using condoms with their partners. Girls with similar-aged partners were less willing to engage in risky sexual behaviours. Findings from this investigation support data from other studies. Relationships with older male partners place adolescent girls at increased risk of HIV/STIs and unintended pregnancy. Adolescent girls in age-discordant relationships are at risk of immediate and long-term sexual health morbidities. Identifying girls who are at increased risk by asking tailored questions will enable nurses to recommend appropriate diagnostics for this population and provide age-specific counselling. © 2013 John Wiley & Sons Ltd.

Left ventricular assist devices (LVAD) are increasingly used, especially as destination therapy in in older patients. The aim of this study was to evaluate the effect of age on renal function and mortality in the first year after implantation. A retrospective multicenter cohort study was conducted, evaluating all LVAD patients implanted in the 2 participating centers (age ≥18 years). Patients were stratified according to the age groups <45, 45-54, 55-64, and ≥65 years old. Overall, 241 patients were included (mean age 52.4 ± 12.9 years, 76% males, 33% destination therapy). The mean estimated Glomerular Filtration Rate (eGFR) at 1 year was 85, 72, 69, and 49 mL/min per 1.73 m 2 in the age groups <45(n = 65, 27%), 45-54(n = 52, 22%), 55-64(n = 87, 36%), and ≥65 years (n = 37, 15%) p <0.001)), respectively. Older age and lower eGFR at baseline (p <0.01) were independent predictors of worse renal function at 1 year. The 1-year survival post-implantation was 79%,84%, 68%, and 54% for those in the age group <45, 45-54, 55-64 and ≥65 years (Log-rank p = 0.003). Older age, lower eGFR and, INTERMACS class I were independent predictors of 1-year mortality. Furthermore, older patients (age > 60 years) with an impaired renal function (eGFR <55 mL/min per 1.73 m 2 ) had a 5-fold increased hazard ratio for mortality during the first year after implantation (p <0.001). In conclusion, age >60 years is an independent predictor for an impaired renal function and mortality. Older age combined with reduced renal function pre-implantation had a cumulative adverse effect on survival in patients receiving a LVAD. Copyright © 2017 Elsevier Inc. All rights reserved.

HIV/AIDS in Older Women: Unique Challenges, Unmet Needs

Durvasula, Ramani

2014-01-01

As persons living with HIV/AIDS live longer, both the prevalence and incidence of HIV infection in older women is expected to increase, and this review presents a model and review of the extant literature on older women with HIV/AIDS in the United States. Older women are rarely addressed in the discourse about HIV risk and prevention, and their concerns are often missed by risk reduction programs that typically target men and younger adults. Societal biases around aging can compound factors such as stigma and disclosure for older women. Primary care providers are often not recommending routine HIV testing to older women, or addressing the impact of age related physiological changes on risk and sexual health. Many older women may be starting new relationships and the role of relational variables that are specific to this group of women are key in understanding prevention and treatment. Empirical research focused on the needs of older women, and recognition of the diverse composition and needs of this group is needed to inform prevention, intervention and best practices with this population of women.

BACKGROUND Kidney transplantation (KT) is a life-prolonging therapy in certain older end-stage renal disease (ESRD) patients, but concerns regarding peri-transplant morbidity remain. We estimate the relative increase in time spent hospitalized in the year post-KT for older versus younger ESRD patients. METHODS This was a retrospective analysis of 27,247 Medicare-primary KT recipients from 2000–2005 using United States Renal Data System and Organ Procurement and Transplantation Network data. Time spent hospitalized was enumerated in the year pre- and post-KT from Medicare Part A claims. Excess inpatient days were the difference in an individual’s post-KT and pre-KT hospital and skilled nursing facility days, standardized by time spent alive in the year post-KT. RESULTS Median excess inpatient days were similar by age group (9 in recipients ≥65 years vs. 7 in recipients < 65 years); however, the distribution was skewed, such that many more older adults had large increases in inpatient time (8.6% totaled > 120 excess inpatient days vs. 4.2% in younger recipients). Among older recipients, risk factors for poor outcomes included recipient age, donor age, longer dialysis vintage, diabetic nephropathy, and congestive heart failure. Reasons for post-transplant hospitalization were similar by age with the exception of rehabilitation, which was common only in the 65+ age group. Mean inpatient costs were equivalent pre-transplant by age but significantly higher post-transplant among older KT recipients. CONCLUSIONS Post-transplant morbidity may not be so different in the majority of older individuals selected for KT; however, a minority fares much worse. PMID:22932116

Disability Rises Gradually for a Cohort of Older Americans

Brown, Dustin C.; Zajacova, Anna

Objectives: We study changes in average disability over nearly two decades for a large epidemiological cohort of older Americans. As some people exit by mortality, do average disability levels for the living cohort rise rapidly, rise gradually, stay steady, or decline? Method: Data are from the Study of Asset and Health Dynamics Among the Oldest Old (AHEAD) cohort for 1993–2010. Cohort members are aged 70+ in 1993 (mean = 77.5 years), and the survivors are aged 87+ in 2010 (mean = 90.2 years). Personal care disability (activities of daily living), household management disability (instrumental activities of daily living), and physical limitations are studied. We study average disability for the living cohort over time and the disability histories for decedent and survivor groups. Results: Average disability rises gradually over time for the living cohort. Earlier decedent groups have higher average disability than later ones. Near death, disability rises sharply for all decedent groups. Longer surviving groups have less average disability, and slower disability increases, than shorter surviving groups. All results are repeated for younger cohort members (baseline age = 70–79 years), older ones (baseline age = 80+ years), women, and men. Discussion: As a cohort ages, average disability among living members increases gradually, signaling behavioral, psychological, and biological fitness in very old persons. PMID:26968638

The purpose of this study was to perform a cost-benefit analysis of the age one dental visit for privately insured patients. A major insurance company provided claims from various states submitted between 2006-2012. Data provided included numbers of procedures and respective costs from the first visit until age six years. Data was organized into five groups based on age, for which the first D0145/D0150 code was submitted [(1) age younger than one year old; (2) age one or older but younger than two years old; (3) age two or older but younger than three years old; (4) age three or older but younger than four years old; and (5) age four or older but younger than five years old]. The ratio of procedures per child and average costs per child were calculated. Claims for 94,574 children were analyzed; only one percent of these children had their first dental visit by age one. The annual cost for children who had their first dental visit by age one was significantly less than for children who waited until an older age. There is an annual cost benefit in establishing a dental home by age one for privately insured patients.

Intelligibility of emotional speech in younger and older adults.

Dupuis, Kate; Pichora-Fuller, M Kathleen

2014-01-01

Little is known about the influence of vocal emotions on speech understanding. Word recognition accuracy for stimuli spoken to portray seven emotions (anger, disgust, fear, sadness, neutral, happiness, and pleasant surprise) was tested in younger and older listeners. Emotions were presented in either mixed (heterogeneous emotions mixed in a list) or blocked (homogeneous emotion blocked in a list) conditions. Three main hypotheses were tested. First, vocal emotion affects word recognition accuracy; specifically, portrayals of fear enhance word recognition accuracy because listeners orient to threatening information and/or distinctive acoustical cues such as high pitch mean and variation. Second, older listeners recognize words less accurately than younger listeners, but the effects of different emotions on intelligibility are similar across age groups. Third, blocking emotions in list results in better word recognition accuracy, especially for older listeners, and reduces the effect of emotion on intelligibility because as listeners develop expectations about vocal emotion, the allocation of processing resources can shift from emotional to lexical processing. Emotion was the within-subjects variable: all participants heard speech stimuli consisting of a carrier phrase followed by a target word spoken by either a younger or an older talker, with an equal number of stimuli portraying each of seven vocal emotions. The speech was presented in multi-talker babble at signal to noise ratios adjusted for each talker and each listener age group. Listener age (younger, older), condition (mixed, blocked), and talker (younger, older) were the main between-subjects variables. Fifty-six students (Mage= 18.3 years) were recruited from an undergraduate psychology course; 56 older adults (Mage= 72.3 years) were recruited from a volunteer pool. All participants had clinically normal pure-tone audiometric thresholds at frequencies ≤3000 Hz. There were significant main effects of emotion, listener age group, and condition on the accuracy of word recognition in noise. Stimuli spoken in a fearful voice were the most intelligible, while those spoken in a sad voice were the least intelligible. Overall, word recognition accuracy was poorer for older than younger adults, but there was no main effect of talker, and the pattern of the effects of different emotions on intelligibility did not differ significantly across age groups. Acoustical analyses helped elucidate the effect of emotion and some intertalker differences. Finally, all participants performed better when emotions were blocked. For both groups, performance improved over repeated presentations of each emotion in both blocked and mixed conditions. These results are the first to demonstrate a relationship between vocal emotion and word recognition accuracy in noise for younger and older listeners. In particular, the enhancement of intelligibility by emotion is greatest for words spoken to portray fear and presented heterogeneously with other emotions. Fear may have a specialized role in orienting attention to words heard in noise. This finding may be an auditory counterpart to the enhanced detection of threat information in visual displays. The effect of vocal emotion on word recognition accuracy is preserved in older listeners with good audiograms and both age groups benefit from blocking and the repetition of emotions.

To examine changes in cause-specific Years of Life Lost (YLL) by age, race, and sex group in the USA from 1990 to 2014. 60 million death reports from the National Center for Health Statistics (NCHS) were categorized by age group, sex, race, and cause of death. YLL were calculated using age-specific life expectancies. Age groups were: infants <1, children 1-19, adults 20-64, and older adults 65+. Blacks have historically experienced more years of life lost than whites or other racial groups in the USA. In the year 1990 the YLL per 100,000 population was 21,103 for blacks, 14,160 for whites, and 7,417 for others. Between 1990 and 2014 overall YLL in the USA improved by 10%, but with marked variations in the rate of change across age, race, and sex groups. Blacks (all ages, both sexes) showed substantial improvement with a 28% reduction in YLL, compared to whites (all ages, both sexes) who showed a 4% reduction. Among blacks, improvements were seen in all age groups: reductions of 43%, 48%, 28%, and 25% among infants, children, adults, and older adults, respectively. Among whites, reductions of 33%, 44%, and 18% were seen in infants, children, and older adults, but there was a 6% increase in YLL among white adults. YLL increased by 18% in white adult females and declined 1% in white adult males. American Indian/Alaska Native women also had worsening in YLL, with an 8% increase. Asian Pacific Islanders consistently had the lowest YLL across all ages. Whites had a higher proportion of YLL due to overdose; blacks had a higher proportion due to homicide at younger ages and to heart disease at older ages. Race-based disparities in YLL in the USA since 1990 have narrowed considerably, largely as a result of improvements among blacks compared to whites. Adult white and American Indian / Alaskan Native females have experienced worsening YLL, while white males have experienced essentially no change. If recent trajectories continue, adult black/white disparities in YLL will continue to narrow.

When reading, low-level visual properties of text are acquired from central vision during brief fixational pauses, but the effectiveness of these properties may differ in older age. To investigate, a filtering technique displayed the low, medium, or high spatial frequencies of text falling within central vision as young (18-28 years) and older (65+ years) adults read. Reading times for normal text did not differ across age groups, but striking differences in the effectiveness of spatial frequencies were observed. Consequently, even when young and older adults read equally well, the effectiveness of spatial frequencies in central vision differs markedly in older age.

There is a fairly consistent, albeit non-universal body of research documenting cognitive declines after cancer and its treatments. While few of these studies have included those 65 and older, it is logical to expect that older patients are at risk of cognitive decline. In this paper, we use breast cancer as an exemplar disease for inquiry into the intersection of aging and cognitive effects of cancer and its therapies. There are a striking number of common underlying potential biological risks and pathways for the development of cancer, cancer-related cognitive declines, and aging processes, including the development of a frail phenotype. Candidate shared pathways include changes in hormonal milieu, inflammation, oxidative stress, DNA damage and compromised DNA repair, genetic susceptibility, decreased brain blood flow or disruption of the blood-brain barrier, direct neurotoxicity, decreased telomere length, and cell senescence. There are also similar structure and functional changes seen in brain imaging studies of cancer patients and those seen with “normal” aging and Alzheimer’s disease. Disentangling the role of these overlapping processes is difficult since they require aged animal models and large samples of older human subjects. From what we do know, frailty and its low cognitive reserve seem to be a clinically useful marker of risk for cognitive decline after cancer and its treatments. This and other results from this review suggest the value of geriatric assessments to identify older patients at the highest risk of cognitive decline. Further research is needed to understand the interactions between aging, genetic predisposition, lifestyle factors and frailty phenotypes to best identify the sub-groups of older patients at greatest risk for decline and to develop behavioral and pharmacological interventions targeting this group. We recommend that basic science and population trials be developed specifically for older hosts with intermediate endpoints of relevance to this group, including cognitive function and trajectories of frailty. Clinicians and their older patients can advance the field by active encouragement of and participation in research designed to improve the care and outcomes of the growing population of older cancer patients.

The aim of this study was to make a comparison between players in two age groups in an elite male soccer team regarding injury localisation within the muscle-tendon unit, injury size and muscle group in terms of muscle injuries of the lower extremity. Cohort study based on data collected from a Swedish elite male soccer team during the seasons 2007-2012. In total, 145 muscle injuries were included. Injury localisation to the tendon or muscle, the size of haematoma and the affected muscle group were assessed using ultrasound. Age comparison was made between younger players (≤23 years) and older players (>23 years). No difference regarding injury localisation to either the tendon or the muscle, or the size of haematoma between the two age groups was found. However, the older group of players suffered a significantly higher number of injuries to the triceps surae than the younger players (p = 0.012). In a Swedish team of male soccer players at elite level, there was no difference between players 23 years or younger and players older than 23 years, in terms of injury distribution to muscles or tendons. Players older than 23 years sustained more injuries to triceps surae when compared with players 23 years or younger. The clinical relevance is to pay attention to muscle function of triceps surae in older players and to screen those players who may need an injury prevention programme. II.

Among typically developing children, having sibling relationships promotes the development of social skills. This is a retrospective study of the effect of having sibling/s on the severity of the clinical presentation of autism spectrum disorder (ASD). The study included 112 children, 99 males and 15 females, mean age 29.6 ± 9.2 months, diagnosed with ASD. The study population was composed of a group of children with ASD who had older typically developing sibling/s (n = 56) pair-matched for age and cognitive level to a group of children with ASD without sibling/s. Each participant underwent a comprehensive assessment using standardized tests. The group with older sibling/s had less severe observed social deficits (Autism Diagnostic Observation Schedule-Social Affect calibrated severity scales [ADOS-SA-CSS]) and fewer reported non-verbal communication impairments (Autism Diagnostic Interview-Revised [ADI-R]). Regression analyses revealed that, for the ADOS-SA-CSS, higher cognitive level and having older sibling/s were associated with less severe observed social affect deficits. This model explained 32.0 % of the variance. For the ADI-R communication scores, older age, higher cognitive level and having older sibling/s were associated with less severe reported non-verbal communication impairments. This model explained 33.0 % of the variance. The main finding in this study is that a familial factor, specifically having older sibling/s, was associated with better social communication abilities in children with ASD, in addition to age and cognitive ability. Having sibling/s may offer opportunities for the child with ASD to experience social interactions with children and to acquire communication skills.

Functional dysphagia (FD) is characterized by the presence of dysphagia without evidence of mechanical esophageal obstruction, GERD, and histopathology-based esophageal motor disorders. Dysphagia is common in older patients; however, there is a paucity of information regarding the type and frequency of peristaltic abnormalities compared to younger patients. Based on recently validated criteria for classification of weak peristalsis using high-resolution manometry (HRM), we hypothesized that older patients with FD would have more peristaltic defects detected by HRM compared to younger FD patients. A retrospective review of our motility database yielded 65 patients that met inclusion criteria. Patients were divided into two groups based on age (younger: <70 years; older: ≥70 years). Patients were interviewed, completed a quality-of-life questionnaire, and underwent solid-state HRM. The two groups differed in age but in no other demographic characteristics, severity of dysphagia, or quality of life. Dyspeptic symptoms, including nausea (p < 0.001), early satiety (p = 0.01), bloating (p = 0.02), and belching (p = 0.01), were also more prevalent in younger FD patients. Older age was associated with weak peristalsis involving frequent failed peristalsis, small proximal peristaltic defects (2-5 cm), and large proximal peristaltic defects (>5 cm) (p < 0.001). The mean contraction amplitude was also lower in the older group (p < 0.05). These data support the hypothesis that older patients with FD have a higher frequency of peristaltic abnormalities on HRM compared to younger patients. Older age was associated with increased frequency of weak peristalsis with small and large peristaltic defects.

Aged care managers' perceptions of staff preparedness for caring for older survivors of genocide and mass trauma in Australia: How prepared are aged care workers?

2017-03-01

To investigate aged care managers' perceptions of staff preparedness for working with older people who experienced genocide or mass trauma earlier in their lives (referred to in this paper as 'older survivors'). A survey of 60 aged care service managers was conducted (50% response rate). Trauma knowledge and skills scales with Cronbach's alpha scores of 0.74 and 0.90 respectively, were used. Scores across groups were compared using Student's t-tests. Three-quarters of the respondents reported that their agency had provided aged care services for older survivors. The majority of these managers perceived their staff to be moderately informed about trauma-related issues and half rated staff trauma-related skills positively. These ratings were positively associated with trauma-related staff training, service type and service location. Results suggest that, overall, managers perceive a need to improve aged care staff's preparedness for providing care for older survivors. © 2016 AJA Inc.

[Purpose] The purpose of the present study was to examine cognitive function in middle-aged and older adults regularly engaging in synchronized swimming-exercise. [Subjects and Methods] Twenty-three female synchronized swimmers ranging in age from 49 to 85 years were recruited for the present study. The duration of synchronized swimming experience ranged from 1 to 39 years. The control group consisted of 36 age- and gender-matched community-dwelling middle-aged and older adults (age range: 49 to 77 years). Cognitive function was evaluated using the Japanese version of the Montreal Cognitive Assessment (MoCA-J) and compared between the synchronized swimmers and control participants. [Results] No significant differences in mean total MoCA-J scores were observed between the synchronized swimmers and control participants (23.2 ± 3.1 and 22.2 ± 3.6, respectively). Twenty-nine subjects in the control group and 17 in the synchronized swimming group scored below 26 on the MoCA-J, indicative of mild cognitive impairment. Significant differences in delayed recall-but not in visuospatial/executive function, naming, attention, language, abstraction, or orientation-were also observed between the two groups. [Conclusion] The results of the present study suggest that synchronized swimming has beneficial effects on cognitive function, particularly with regard to recent memory.

Medial prefrontal cortex supports source memory for self-referenced materials in young and older adults

PubMed Central

Leshikar, Eric D.; Duarte, Audrey

2013-01-01

Behavioral evidence suggests that young and older adults show a benefit in source memory accuracy when processing materials in reference to the self. In the young, activity within the medial prefrontal cortex supports this source memory benefit at study. This investigation examined whether the same neural regions support this memory benefit in both age groups. Using fMRI, participants were scanned while studying and retrieving pictures of objects paired with one of three scenes (source) under self-reference and other-reference conditions. At the time of study, half of the items were presented once and half twice, allowing us to match behavioral performance between groups. Both groups showed equivalent source accuracy benefit for objects encoded self-referentially. Activity in the left dorsal medial prefrontal cortex supported subsequent source memory in both age groups for the self-referenced relative to the other-referenced items. At the time of test, source accuracy for both self- and other-referenced items was supported by a network of regions including the precuneus in both age groups. At both study and test, little in the way of age-differences emerged, suggesting that when matched on behavioral performance young and older adults engage similar regions in support of source memory when processing materials in reference to the self; however, when performance was not matched, age differences in functional recruitment were prevalent. These results suggest that by capitalizing on preserved processes (self-referential encoding), older adults can show improvement in memory for source details which typically are not well remembered relative to the young.

Aging is associated with a large heterogeneity in the extent of age-related changes in sensory, motor, and cognitive functions. All these functions can influence the performance in complex tasks like car driving. The present study aims to identify potential differences in underlying cognitive processes that may explain inter-individual variability in driving performance. Younger and older participants performed a one-hour monotonous driving task in a driving simulator under varying crosswind conditions, while behavioral and electrophysiological data were recorded. Overall, younger and older drivers showed comparable driving performance (lane keeping). However, there was a large difference in driving lane variability within the older group. Dividing the older group in two subgroups with low vs. high driving lane variability revealed differences between the two groups in electrophysiological correlates of mental workload, consumption of mental resources, and activation and sustaining of attention: Older drivers with high driving lane variability showed higher frontal Alpha and Theta activity than older drivers with low driving lane variability and—with increasing crosswind—a more pronounced decrease in Beta activity. These results suggest differences in driving strategies of older and younger drivers, with the older drivers using either a rather proactive and alert driving strategy (indicated by low driving lane variability and lower Alpha and Beta activity), or a rather reactive strategy (indicated by high driving lane variability and higher Alpha activity).

Older adults are susceptible to adverse effects from opioids, nonsteroidal anti-inflammatory drugs (NSAIDs), and benzodiazepines (BZDs). We investigated factors associated with the administration of elevated doses of these medications of interest to older adults (≥65 years old) in the emergency department (ED). ED records were queried for the administration of medications of interest to older adults at two academic medical center EDs over a 6-month period. Frequency of recommended versus elevated ("High doses" were defined as doses that ranged between 1.5 and 3 times higher than the recommended starting doses; "very high doses" were defined as higher than high doses) starting doses of medications, as determined by geriatric pharmacy/medicine guidelines and expert consensus, was compared by age groups (65-69, 70-74, 75-79, 80-84, and ≥85 years), gender, and hospital. There were 17896 visits representing 11374 unique patients >65 years of age (55.3% men, 44.7% women). A total of 3394 doses of medications of interest including 1678 high doses and 684 very high doses were administered to 1364 different patients. Administration of elevated doses of medications was more common than that of recommended doses. Focusing on opioids and BZDs, the 65-69-year age group was much more likely to receive very high doses (1481 and 412 doses, respectively) than the ≥85-year age groups (relative risk [RR] 5.52, 95% CI 2.56-11.90), mainly reflecting elevated opioid dosing (RR 8.28, 95% CI 3.69-18.57). Men were more likely than women to receive very high doses (RR 1.47, 95% CI 1.26-1.72), primarily due to BZDs (RR 2.12, 95% CI 2.07-2.16). Administration of elevated doses of opioids and BZDs in the older population occurs frequently in the ED, especially to the 65-69-year age group and men. Further attention to potentially unsafe dosing of high-risk medications to older adults in the ED is warranted.

Methodological Challenges in Physical Activity Research with Older Adults

The aging adult population is growing, as well as the incidence of chronic illness among older adults. Physical activity has been demonstrated in the literature to be a beneficial component of self-management for chronic illnesses commonly found in the older adult population. Health sciences research seeks to develop new knowledge, practices, and policies that may benefit older adults’ management of chronic illness and quality of life. However, research with the older adult population, though beneficial, includes potential methodological challenges specific to this age group. This article discusses common methodological issues in research among older adults, with a focus on physical activity intervention studies. Awareness and understanding of these issues may facilitate future development of research studies devoted to the aging adult population, through appropriate modification and tailoring of sampling techniques, intervention development, and data measures and collection.

Objective This study aimed to determine the combined effects of age and HIV infection on the risk of incident neurocognitive disorders. Method A total of 146 neurocognitively normal participants were enrolled at baseline into one of four groups based on age (≤ 40 years and ≥ 50 years) and HIV serostatus resulting in 24 younger HIV−, 27 younger HIV+, 39 older HIV−, and 56 older HIV+ individuals. All participants were administered a standardized clinical neuropsychological battery at baseline and 14.3 ±0.2 months later. Results A logistic regression predicting incident neurocognitive disorders from HIV, age group, and their interaction was significant (χ2[4] = 13.56, p = .009), with a significant main effect of HIV serostatus (χ2[1] = 5.01, p = .025), but no main effect of age or age by HIV interaction (ps > .10). Specifically, 15.7 percent of the HIV+ individuals had an incident neurocognitive disorder as compared to 3.2 percent of the HIV− group (odds ratio = 4.8 [1.2, 32.6]). Among older HIV+ adults, lower baseline cognitive reserve, prospective memory, and verbal fluency each predicted incident neurocognitive disorders at follow-up. Conclusions Independent of age, HIV infection confers a nearly 5-fold risk for developing a neurocognitive disorder over approximately one year. Individuals with lower cognitive reserve and mild weaknesses in higher-order neurocognitive functions may be targeted for closer clinical monitoring and preventative measures. PMID:26367342

Effects of context on the perception of, and incidental memory for, real-world objects have predominantly been investigated in younger individuals, under conditions involving a single static viewpoint. We examined the effects of prior object context and object familiarity on both older and younger adults’ incidental memory for real objects encountered while they traversed a conference room. Recognition memory for context-typical and context-atypical objects was compared with a third group of unfamiliar objects that were not readily named and that had no strongly associated context. Both older and younger adults demonstrated a typicality effect, showing significantly lower 2-alternative-forced-choice recognition of context-typical than context-atypical objects; for these objects, the recognition of older adults either significantly exceeded, or numerically surpassed, that of younger adults. Testing-awareness elevated recognition but did not interact with age or with object type. Older adults showed significantly higher recognition for context-atypical objects than for unfamiliar objects that had no prior strongly associated context. The observation of a typicality effect in both age groups is consistent with preserved semantic schemata processing in aging. The incidental recognition advantage of older over younger adults for the context-typical and context-atypical objects may reflect aging-related differences in goal-related processing, with older adults under comparatively more novel circumstances being more likely to direct their attention to the external environment, or age-related differences in top-down effortful distraction regulation, with older individuals’ attention more readily captured by salient objects in the environment. Older adults’ reduced recognition of unfamiliar objects compared to context-atypical objects may reflect possible age differences in contextually driven expectancy violations. The latter finding underscores the theoretical and methodological value of including a third type of objects–that are comparatively neutral with respect to their contextual associations–to help differentiate between contextual integration effects (for schema-consistent objects) and expectancy violations (for schema-inconsistent objects).

Gaze following is the primary means of establishing joint attention with others and is subject to age-related decline. In addition, young but not older adults experience an own-age bias in gaze following. The current research assessed the effects of subconscious processing on these age-related differences. Participants responded to targets that were either congruent or incongruent with the direction of gaze displayed in supraliminal and subliminal images of young and older faces. These faces displayed either neutral (Study 1) or happy and fearful (Study 2) expressions. In Studies 1 and 2, both age groups demonstrated gaze-directed attention by responding faster to targets that were congruent as opposed to incongruent with gaze-cues. In Study 1, subliminal stimuli did not attenuate the age-related decline in gaze-cuing, but did result in an own-age bias among older participants. In Study 2, gaze-cuing was reduced for older relative to young adults in response to supraliminal stimuli, and this could not be attributed to reduced visual acuity or age group differences in the perceived emotional intensity of the gaze-cue faces. Moreover, there were no age differences in gaze-cuing when responding to subliminal faces that were emotionally arousing. In addition, older adults demonstrated an own-age bias for both conscious and subconscious gaze-cuing when faces expressed happiness but not fear. We discuss growing evidence for age-related preservation of subconscious relative to conscious social perception, as well as an interaction between face age and valence in social perception.

We aimed to see whether primary percutaneous coronary intervention (PCI) benefits for ST-segment elevation myocardial infarction (STEMI) in the aged could be validated. Primary PCI benefits in elderly patients with STEMI remain uncertain. We reviewed 947 consecutive patients treated with primary PCI for STEMI: 331 were aged ≥75 years (older) and 616 <75 years (younger). The older group had higher percentage of renal insufficiency (7.9% vs. 3.1%, P = 0.0010), prior stroke (9.4% vs. 3.9%, P = 0.0006), 30-day mortality rate (7.6% vs. 3.9%, P = 0.015), and cardiac mortality rate (6.6% vs. 3.7%, P = 0.045). Successful reperfusion rates were similarly high in both groups (90.0% and 92.7%, P = 0.16), despite the higher proportion of patients with door-to-balloon time >90 min (15% vs. 8.4%, P = 0.0016) in older patients. Successful compared with unsuccessful PCI significantly decreased 30-day mortality rates in the older group (6.0% vs. 21%, P = 0.0018) and in the younger group (2.8% vs. 18%, P < 0.0001). When reperfusion was successful, cardiac mortality rate in older patients was not significantly greater than in younger patients (5.4% vs. 2.8%, P = 0.057). By multivariate analysis, unsuccessful reperfusion independently predicted 30-day mortality (odds ratio, 4.04; 95% confidence interval, 1.79-9.12; P = 0.0008), whereas age ≥75 years (odds ratio, 1.00; 95% confidence interval, 0.41-2.41; P = 0.99) and door-to-balloon time >90 min (odds ratio, 1.78; 95% confidence interval, 0.76-4.20; P = 0.19) did not. Pre-existing comorbidities characterize older patients developing STEMI. Aggressive PCI in older patients improves prognosis, and short door-to-balloon time is an important parameter conditioning the prognosis. Copyright © 2011 Wiley Periodicals, Inc.

To calculate indices of inequality and inequity in the use of medical services for children, adults, and older adults in Chile from 2000 to 2011. Based on the CASEN survey (2000-2011), the concentration index (CI) was calculated to measure inequality and the horizontal inequity index (HI) was calculated to measure inequity in the use of medical services. Four groups were studied: children under 5, children aged 6-18 years, adults, and older adults. The results indicate higher levels of inequality in the use of specialized physician services in the child groups, and higher levels of inequity in the adult group. In the use of dental services, the greatest inequality and inequity is found among older adults. For visits to emergency services in the last two years for which data are available (2009 and 2011), the adult group shows a higher level of inequality. In terms of levels of inequity and inequality, there are differences among children, adults, and older adults over the years in at least three of the six variables studied.

To examine the relation of age with symptom severity and quality of life (QOL) in patients with fibromyalgia, and to compare physical and mental health of our female patients with those of the US female general population. We studied 978 patients with fibromyalgia from May 1, 2001 through April 30, 2004, and divided them into age groups of young (≤39 years), middle-aged (40-59 years), and older (≥60 years). They completed the Fibromyalgia Impact Questionnaire and the Short Form-36 Health Status Questionnaire (SF-36). Standardized SF-36 physical and mental health summary scores were compared with those of the US female general population of similar age. One-way analysis of variance and post hoc paired t test analyses were performed to detect differences across age groups. Pairwise comparison found young and middle-aged patients having worse fibromyalgia symptoms in all subscales except the anxiety subscale compared with older patients (P≤.01). Similarly, these young and middle-aged patients had worse QOL in the SF-36 mental component summary, as well as SF-36 general health perceptions, vitality, social functioning, and mental health index, compared with older patients (all P<.001). When the QOL of our female patients was compared with that of the US female general population of similar age with standardized SF-36 scores, all age groups had lower QOL in physical, as well as mental, health, with more reduction in physical health, particularly in young patients. Our study shows that symptom severity and QOL differ across age groups in patients with fibromyalgia, with young and middle-aged patients having poorer QOL and worse fibromyalgia symptoms than do older patients. QOL in physical health was reduced more than in mental health, particularly in young patients, compared with the general population.

Age-related differences in goals: testing predictions from selection, optimization, and compensation theory and socioemotional selectivity theory.

PubMed

Penningroth, Suzanna L; Scott, Walter D

2012-01-01

Two prominent theories of lifespan development, socioemotional selectivity theory and selection, optimization, and compensation theory, make similar predictions for differences in the goal representations of younger and older adults. Our purpose was to test whether the goals of younger and older adults differed in ways predicted by these two theories. Older adults and two groups of younger adults (college students and non-students) listed their current goals, which were then coded by independent raters. Observed age group differences in goals generally supported both theories. Specifically, when compared to younger adults, older adults reported more goals focused on maintenance/loss prevention, the present, emotion-focus and generativity, and social selection, and less goals focused on knowledge acquisition and the future. However, contrary to prediction, older adults also showed less goal focusing than younger adults, reporting goals from a broader set of life domains (e.g., health, property/possessions, friendship).

The Red Hat Society: Exploring the role of play, liminality, and communitas in older women's lives.

There is an extensive literature on play. Yet, the role of play in older adults' lives has received limited attention. Strikingly absent is research on play and older women. Missing from the literature is how older women use play as a liminal context for social interaction and communitas. This is odd because by 2030 one in four American women will be over the age of sixty-five. The primary purpose of this study is to explore the roles of play, liminality, and communitas in older women's lives. The focus is the Red Hat Society, a social group for women over age 50 that fosters play and fun. Using qualitative interviews with focus groups and participant observation of a regional Red Hat Society event, the study highlights some of the strengths and weaknesses of current conceptualizations of play, liminality, and communitas.

Group differences in anterior hippocampal volume and in the retrieval of spatial and temporal context memory in healthy young versus older adults.

The ability to retrieve temporal and spatial context information from memory declines with healthy aging. The hippocampus (HC) has been shown to be associated with successful encoding and retrieval of spatio-temporal context, versus item recognition information (Davachi, Mitchell, & Wagner, 2003; Nadel, Samsonovich, Ryan, & Moscovitch, 2000; Ross & Slotnick, 2008). Aging has been linked to volume reduction in the HC (Bouchard, Malykhin, Martin, Hanstock, Emery, Fisher, & Camicioli, 2008; Malykhin, Bouchard, Camicioli, & Coupland, 2008; Raz et al., 2005). As such, age-associated reductions in anterior HC volume may contribute to the context memory deficits observed in older adults. In the current MRI study we investigated whether item recognition, spatial context and temporal context memory performance would be predicted by regional volumes in HC head (HH), body (HB) and tail (HT) volumes, using within group multiple regression analyses in a sample of 19 healthy young (mean age 24.3) and 20 older adults (mean age 67.7). We further examined between age-group differences in the volumes of the same HC sub-regions. Multiple regression analyses revealed that in younger adults both spatial and temporal context retrieval performance was predicted by anterior HC volume. Older age was associated with significant volume reductions in HH and HB, but not HT; and with reduced ability to retrieve spatial and temporal contextual details from episodic memory. However, HC volumes did not predict context retrieval performance in older adults. We conclude that individual differences in anterior, not posterior, HC volumes predict context memory performance in young adults. With age there may be a posterior-to-anterior shift from using HC-related processes, due to HC volume loss, to employing the prefrontal cortex to aid in the performance of cognitively demanding context memory tasks. However, due to concomitant changes in the prefrontal system with age, there are limits to compensation in the aging brain. Crown Copyright © 2010. Published by Elsevier Ltd. All rights reserved.

Older orthopaedic patients' perceptions of individualised care: a comparative survey.

To describe and compare the individualised care perceptions of older orthopaedic patients' and patients of working age. Age has been found to influence perceptions of care and although individualised care is highlighted in the literature, it is seldom studied from an older person's perspective. Descriptive and comparative. Data were collected using the Individualised Care Scale from orthopaedic patients (n = 420, response rate 84%). The participants were divided into two groups: those 65 and over (n = 149) and those under 65 and working (n = 271). Data analysis used descriptive and inferential statistics. Patients expressed a desire for individualised care, and gave relatively good evaluations about the perceived support for their individuality and the realisation of individualised care. Differences in the perceptions of individualised care were found between, but not within, the two groups. The older patients were more positive in their evaluations. There is a need for programmes of individualised care that are age-adjusted. As the older population rises worldwide individualised care becomes more important in the care of older people. These findings provide baseline data for the development of individualised nursing care from the patients' perspective. © 2010 Blackwell Publishing Ltd.

Older Adults with Hoarding Behaviour Aging in Place: Looking to a Collaborative Community-Based Planning Approach for Solutions

This paper reports on and synthesizes new research that examines how a collaborative community response can promote successful aging in place for older adults with hoarding behaviour. Through interviews with older adults with hoarding behaviour, who used a particular community support and a focus group interview with members of the community collaborative that directed supports for this population, our findings suggest that there were valuable outcomes for both groups. These older adults with hoarding behaviour were able to remain in their own homes, their safety was enhanced, their sense of isolation was minimized, empowerment was fostered, and they gained valuable insight into their behaviour. The members of the community collaborative were able to access the expertise of other professionals, maximize their own expertise, and they generated an enhanced understanding of the experience of older adults living with hoarding behaviour in Edmonton. This study is a significant addition to the much too sparse literature about the community planning needs of older adults with hoarding behaviour. It offers knowledge that is integral to theories and principles of better aging in place but attempts to translate this into practice. PMID:22013529

Spatial and temporal processing in healthy aging: implications for perceptions of driving skills.

PubMed

Conlon, Elizabeth; Herkes, Kathleen

2008-07-01

Sensitivity to the attributes of a stimulus (form or motion) and accuracy when detecting rapidly presented stimulus information were measured in older (N = 36) and younger (N = 37) groups. Before and after practice, the older group was significantly less sensitive to global motion (but not to form) and less accurate on a rapid sequencing task when detecting the individual elements presented in long but not short sequences. These effect sizes produced power for the different analyses that ranged between 0.5 and 1.00. The reduced sensitivity found among older individuals to temporal but not spatial stimuli, adds support to previous findings of a selective age-related deficit in temporal processing. Older women were significantly less sensitive than older men, younger men and younger women on the global motion task. Gender effects were evident when, in response to global motion stimuli, complex extraction and integration processes needed to be undertaken rapidly. Significant moderate correlations were found between age, global motion sensitivity and reports of perceptions of other vehicles and road signs when driving. These associations suggest that reduced motion sensitivity may produce functional difficulties for the older adults when judging speeds or estimating gaps in traffic while driving.

Objective To generate reference values and t-scores (1.0 to 2.5 standard deviations below average) for grip strength for healthy young adults and to examine the utility of t-scores from this group for the identification of dynapenia in older adults. Design Secondary analysis of cross-sectional grip strength data from the NIH Toolbox norming sample. Setting Population-based general community sample. Participants Community dwelling adults, between the ages 20 and 40 years (n=558); and 60 to 85 years (n=390) Main Outcomes Measures Grip strength measured with a Jamar plus dynamometer. Results Maximum grip strengths were consistent over the 20–40 year age span. For men they were 108.0 lbs (S.D. 22.6). For women, they were 65.8 lbs (S.D. 14.6) Comparison of older participant grip strengths to those of the younger reference group revealed (depending on age strata) that 46.2–87.1% of older men and 50.0–82.4% of older women could be designated as dynapenic on the basis of t-scores. Conclusion The use of reference value t-scores from younger adults is a promising method for determining dynapenia in older adults. PMID:24729356

Background Previous studies suggest older adults may be differentially susceptible to the acute neurobehavioral effects of moderate alcohol intake. To our knowledge, no studies have addressed acute moderate alcohol effects on the electrophysiological correlates of working memory in younger and older social drinkers. This study characterized alcohol-related effects on frontal theta (FTP) and posterior alpha power (PAP) associated with maintenance of visual information during a working memory task. Methods Older (55–70 years of age; n = 51, 29 women) and younger (25–35 years of age; n = 70, 39 women) community-dwelling moderate drinkers were recruited for this study. Participants were given either placebo or an active dose targeting breath alcohol concentrations (BrACs) of 0.04 or 0.065 g/dL. Following absorption, participants completed a visual working memory task assessing cue recognition following a 9s delay. FTP and PAP were determined via Fourier transformation and subjected to 2 (age group) X 3 (dose) X 2 (repeated: working memory task condition) mixed models analysis. Results In addition to expected age-related reductions in PAP, a significant age group X dose interaction was detected for PAP such that 0.04 g/dL dose level was associated with greater PAP in younger adults but lower PAP in their older counterparts. PAP was lower in older vs younger adults at both active doses. Further mixed models revealed a significant negative association between PAP and working memory efficiency for older adults. No effects of age, dose, or their interaction were noted for FTP. Conclusions Results bolster the small but growing body of evidence that older adults exhibit differential sensitivity to the neurobehavioral effects of moderate alcohol use. Given the theoretical role of PAP in attentional and working memory function, these findings shed light on the attentional mechanisms underlying effects of acute moderate alcohol on working memory efficiency in older adults.

Is Acute Myocardial Infarction Disappearing?

Following a peak in the mid 1960s, there has been a steady decline in coronary heart disease (CHD) mortality in the United States of 2.8%/y to 5.1%/y.1,2 This shift in mortality patterns is most dramatic in the age-adjusted rates. Age adjustment compensates for the transition of CHD in older age groups and the increase in the aged population. The absolute number of total CHD deaths showed little change until recently (Figure 1). Life expectancy of adults dramatically increased, largely as a result of these improved CHD outcomes.3 However, the reduction in mortality was not associated with a decline in hospital morbidity as CHD was pushed into the older age groups.1 Prevalence actually increased with more individuals diagnosed, treated, and surviving.1 CHD hospitalizations for those >65 years of age increased from 1965 to 2000 while declining in younger age groups.1 PMID:20212286

Cognitive impairment, dementia, and personality stability among older adults

There is contrasting evidence on personality stability in advanced age, and limited knowledge on the impact of cognitive impairment and dementia on trait stability. Group- and individual-level longitudinal analyses of the five major dimensions of personality assessed twice over 4-years (N = 9,935) suggest that rank-order stability was progressively lower with advancing age (from rtt = 0.68 for age 50–60 to rtt = 0.58 for age >80 years). Stability was low in the dementia group (rtt = 0.43), and this was not simply due to lower reliability given that internal consistency remained adequate in the dementia group. Among individuals with no cognitive impairment or dementia, there was no association between stability and age (rtt = 0.70 even for age >80). These results suggest that the lower personality stability in older adults is not due to age but cognitive impairment and dementia. PMID:29214858

Age Differences in Consumer Decision Making under Option Framing: From the Motivation Perspective

Option framing effect is the phenomena that participants often accept more options when they are asked to delete undesired options from a full model (subtractive framing) than they do when they are instructed to add desired options to a base model (additive framing). Whether the same effect exists in different age groups is less well known. To explore the roles of age and purchase motivations on the option framing effect for automobiles purchases, this study adopted a 3 (age group: younger, middle-aged, vs. older) × 2 (option framing: additive vs. subtractive) × 2 (focus condition: information vs. emotion) mixed design. To manipulate purchase motivations, participants in the three age groups were instructed to focus on the ratio of utility and price of options (information-focus) or the extent of pleasure induced by the options (emotion-focus) when they made purchase decisions in two framing conditions. The results revealed similar option framing effect across all age groups in the information-focus condition regarding the total price paid for accepted options. In contrast, the framing effect was not found in the emotion-focus condition. In addition, older adults accepted more options and an overall higher price than younger and middle-aged adults in both focus conditions. This difference was more obvious in the emotion-focus condition than in the information-focus condition. Moreover, both the number of accepted options and the total accepted price of the younger group in the information-focus condition were higher than those in the emotion-focus condition, whereas the older and middle-aged groups accepted same number of options and price between two focus conditions. These results imply that purchase motivation is a moderator of the option framing effect and age characteristics linked with motivations must be considered in sales. PMID:27872603

While community-wide interventions to promote physical activity have been encouraged in older adults, evidence of their effectiveness remains limited. We conducted a qualitative study among older adults participating in regular group exercise to understand their perceptions of the physical, mental, and social changes they underwent as a result of the physical activity. We conducted a qualitative study with purposeful sampling to explore the experiences of older adults who participated in regular group exercise as part of a community-wide physical activity intervention. Four focus group interviews were conducted between April and June of 2016 at community halls in Fujisawa City. The participants in the focus group interviews were 26 older adults with a mean age of 74.69 years (range: 66-86). The interviews were analysed using the constant comparative method in the grounded theory approach. We used qualitative research software NVivo10® to track the coding and manage the data. The finding 'regular group exercise contributes to balanced health in older adults' emerged as an overarching theme with seven categories (regular group exercise, functional health, active mind, enjoyment, social connectedness, mutual support, and expanding communities). Although the participants perceived that they were aging physically and cognitively, the regular group exercise helped them to improve or maintain their functional health and enjoy their lives. They felt socially connected and experienced a sense of security in the community through caring for others and supporting each other. As the older adults began to seek value beyond individuals, they gradually expanded their communities beyond geographical and generational boundaries. The participants achieved balanced health in the physical, mental, and social domains through regular group exercise as part of a community-wide physical activity intervention and contributed to expanding communities through social connectedness and mutual support. Health promotion through physical activity is being increasingly emphasized. The study results can help to develop effective physical activity programs for older adults in the community.

Cases of type 1 diabetes mellitus in children aged younger than 6 years in Taiwan has increased in the past 10 years. This retrospective study aimed to review the management experience of such patients in a single center. From January 2004 to June 2015, 52 newly diagnosed diabetic children younger than 6 years who had regular follow-up for > 1 year were enrolled, as well as 94 older diabetic children for comparison. Their medical records were thoroughly reviewed. The most common symptoms and signs were polyuria, polydipsia, dry lips, weight loss, and nocturia. Among the children younger than 6 years, 87% had ketoacidosis upon diagnosis-significantly higher than that of the older age group-and 88% had at least one islet cell autoantibody detected. Their serum C-peptide levels were significantly lower and the frequency of insulin autoantibodies detected was significantly higher compared with the older age group (37% vs. 10%). The remission rate of the young diabetic patients was significantly lower than that of the older age group (40% vs. 59%), but there was no difference in time of onset and duration of remission between the two groups. Autoimmune destruction of pancreatic β-cells is an important cause of type 1 diabetes mellitus in Taiwanese children aged younger than 6 years. These patients usually have a low insulin reserve and severe ketoacidosis upon diagnosis. A high index of suspicion in the presence of classic symptoms of diabetes in young children is important to prevent complications. Copyright © 2016. Published by Elsevier B.V.

Gender differences among older heroin users.

PubMed

Hamilton, Alison B; Grella, Christine E

2009-01-01

This purpose of this study was to explore the following question: Are there gender differences among older individuals with a history of heroin addiction with regard to social and family relationships and health problems? Eight gender-specific focus groups were conducted with 38 (19 women, 19 men) older (50+ years) individuals with long-term histories of heroin dependence. Four groups were conducted in a methadone maintenance (MM) clinic and four groups were derived from the Los Angeles community. Modest gender differences were observed, but mainly in the focus-group dynamics. Women typically described the impact of their addiction on their families, while men typically described their surprise at still being alive. Hepatitis C was the primary health concern in all groups; mental health issues were also discussed. Remarkable gender differences were not apparent in the qualitative experiences of these participants. Instead, we found overriding similarities related to the interactive effects of drug use and aging. Longitudinal studies of this population as they age and interact with the health-care system and other social systems will help to untangle the complicated relationship between aging, drug addiction, gender, and health.

Age-related ventricular-vascular coupling during acute inflammation in humans: Effect of physical activity.

Aging is commonly accompanied by increased arterial and ventricular stiffness (determined by arterial elastance (Ea) and ventricular elastance (Elv)), augmented ventricular-vascular coupling ratios (Ea/Elv) and systemic inflammation. Acute inflammation may impact ventricular-vascular coupling and predispose older adults to cardiovascular events. However, physically active older adults have more compliant large arteries and left ventricles and lower inflammation than sedentary older adults. We hypothesized that acute inflammation would alter Ea, Elv, and Ea/Elv more in older versus younger adults but that higher levels of physical activity would attenuate inflammation-induced changes. End-systolic and central blood pressures were obtained using applanation tonometry before and at 24 and 48 h post-influenza vaccination in 24 older and 38 younger adults. Ultrasonography was used to measure ventricular volumes and other indices of cardiac performance. Physical activity was measured with accelerometry. Ea and Ea/Elv were maintained (p > 0.05), but Elv was reduced (p < 0.05) 24 h post-inflammation. Other indices of systolic performance were reduced in older but not younger adults; diastolic performance was attenuated in both groups 24 h post-inflammation (p < 0.05 for all). Older, but not younger, adults decreased central pressure during inflammation (p < 0.05). When controlled for age, physical activity was not related to the inflammation-induced changes in elastance (p > 0.05) except in the most active group of seniors (p < 0.05). Aging did not affect the elastance responses but did affect central blood pressure and other ventricular systolic responses to acute inflammation. Aging, not physical activity, appears to modulate cardiovascular responses to acute inflammation, except in the most active older adults. © The European Society of Cardiology 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

This study aims at assessing the gap in secondary fracture prevention at a regional general hospital setting in Singapore. Male patients have significantly lower rate of being investigated and treated for osteoporosis than their female counterparts. Vitamin D deficiency is prevalent in our population. Secondary fracture prevention services are not routine in Singapore; we seek to assess the treatment gap that exists in the lack of diagnosis and treatment of osteoporosis in fragility fracture patients. We performed a retrospective analysis of all admissions for fragility fractures between December 2013 and December 2014. Demographic data, rates of BMD performance, serum vitamin D investigation and calcium and vitamin D supplementation as well as antiresorptive initiation 1 year post admission were analysed. There were 125 fragility fractures in patients below 65 and 615 fractures in older patients. There was a slightly higher proportion of males in the younger population, whereas females predominated in the older population. Median vitamin D levels were low in both younger (19.1 μg/L) and older (22.0 μg/L) groups, but supplementation was lower in younger patients (4.8 versus 16.6%, p = 0.003). Rate of BMD performance was lower in younger patients (34.4 versus 64.6%, p < 0.01); there was a significant difference of BMD performance between male and female patients in the younger population (19.1 versus 52.8%, p < 0.01) which was not present in the older age group. Antiresportive initiation was significantly lower in the younger age group versus older (10.4 versus 31.5%, p < 0.01); male patients in the younger and older age groups had significantly lower antiresorptive initiation rate compared to the females. There is a significant treatment gap in diagnosis and treatment of osteoporosis in fragility fracture patients in a regional hospital setting in Singapore. Male osteoporosis remains inadequately investigated and treated in both age groups.

Representational Account of Memory: Insights from Aging and Synesthesia.

The representational account of memory envisages perception and memory to be on a continuum rather than in discretely divided brain systems [Bussey, T. J., & Saksida, L. M. Memory, perception, and the ventral visual-perirhinal-hippocampal stream: Thinking outside of the boxes. Hippocampus, 17, 898-908, 2007]. We tested this account using a novel between-group design with young grapheme-color synesthetes, older adults, and young controls. We investigated how the disparate sensory-perceptual abilities between these groups translated into associative memory performance for visual stimuli that do not induce synesthesia. ROI analyses of the entire ventral visual stream showed that associative retrieval (a pair-associate retrieved in the absence of a visual stimulus) yielded enhanced activity in young and older adults' visual regions relative to synesthetes, whereas associative recognition (deciding whether a visual stimulus was the correct pair-associate) was characterized by enhanced activity in synesthetes' visual regions relative to older adults. Whole-brain analyses at associative retrieval revealed an effect of age in early visual cortex, with older adults showing enhanced activity relative to synesthetes and young adults. At associative recognition, the group effect was reversed: Synesthetes showed significantly enhanced activity relative to young and older adults in early visual regions. The inverted group effects observed between retrieval and recognition indicate that reduced sensitivity in visual cortex (as in aging) comes with increased activity during top-down retrieval and decreased activity during bottom-up recognition, whereas enhanced sensitivity (as in synesthesia) shows the opposite pattern. Our results provide novel evidence for the direct contribution of perceptual mechanisms to visual associative memory based on the examples of synesthesia and aging.

Memory for staged events: Supporting older and younger adults' memory with SenseCam.

Two experiments measured the effect of retrieval support provided by a wearable camera, SenseCam, on older and younger adults' memory for a recently experienced complex staged event. In each experiment, participants completed a series of tasks in groups, and the events were recalled 2 weeks later, after viewing SenseCam images (experimental condition) or thinking about the event (control condition). When IQ and education were matched, young adults recalled more event details than older adults, demonstrating an age-related deficit for novel autobiographical material. Reviewing SenseCam images increased the number of details recalled by older and younger adults, and the effect was similar for both groups. These results suggest that memory can be supported by the use of SenseCam, but the age-related deficit is not eliminated.

Oral-diadochokinetic rates for Hebrew-speaking healthy ageing population: non-word versus real-word repetition.

Oral-diadochokinesis (oral-DDK) tasks are extensively used in the evaluation of motor speech abilities. Currently, validated normative data for older adults (aged 65 years and older) are missing in Hebrew. The effect of task stimuli (non-word versus real-word repetition) is also non-clear in the population of older adult Hebrew speakers. (1) To establish a norm for oral-DDK rate for older adult (aged 65 years and older) Hebrew speakers, and to investigate the possible effect of age and gender on performance rate; and (2) to examine the effects of stimuli (non-word versus real word) on oral-DDK rates. In experiment 1, 88 healthy older Hebrew speakers (60-95 years, 48 females and 40 males) were audio-recorded while performing an oral-DDK task (repetition of /pataka/), and repetition rates (syllables/s) were coded. In experiment 2, the effect of real-word repetition was evaluated. Sixty-eight older Hebrew speakers (aged 66-95 years, 43 females and 25 males) were asked to repeat 'pataka' (non-word) and 'bodeket' (Hebrew real word). Experiment 1: Oral-DDK performance for older adult Hebrew speakers was 5.07 syllables/s (SD = 1.16 syllables/s), across age groups and gender. Comparison of this data with Hebrew norms for younger adults (and equivalent data in English) shows the following gradient of oral-DDK rates: ages 15-45 > 65-74 > 75-86 years. Gender was not a significant factor in our data. Experiment 2: Repetition of real words was faster than that of non-words, by 13.5%. The paper provides normative values for oral-DDK rates for older Hebrew speakers. The data show the large impact of ageing on oro-motor functions. The analysis further indicates that speech and language pathologists should consider separate norms for clients of 65-74 years and those of 75-86 years. Hebrew rates were found to be different from English norms for the oldest group, shedding light on the impact of language on these norms. Finally, the data support using a dual-protocol (real- and non-word repetition) with older adults to improve differential diagnosis of normal and pathological ageing in this task. © 2016 Royal College of Speech and Language Therapists.

We investigated the effect of age and color in a computerized version of the jigsaw-puzzle task. In Experiment 1, young and older adults were presented with puzzles in color and black-and-white line drawings, varying in difficulty from 4 to 9 pieces. Older adults performed the task better with the black-and-white stimuli and younger adults performed better with the color ones. In Experiment 2, new older and young adults identified the same fragmented pictures as fast and accurately as possible. The older group identified the black-and-white stimuli faster than those presented in color, while the younger adults identified both similarly. In Experiment 3A, new older and young groups performed the puzzle task with the same color pictures and their monochrome versions. In Experiment 3B, participants performed a speeded identification task with the two sets. The findings of these experiments showed that older adults have a memory not a perceptual difficulty.

The study identifies differences in age-expectations between older adults from Korean, Chinese, Latino, and African American backgrounds living in the United States. This study uses baseline demographic, age-expectation, social, and health data from 229 racial/ethnic minority seniors in a stroke-prevention intervention trial. Unadjusted regression models and pair-wise comparisons tested for racial/ethnic differences in age-expectations, overall, and across domain subscales (e.g., physical-health expectations). Adjusted regression models tested whether age-expectations differed across racial/ethnic groups after controlling for demographic, social, and health variables. Regression and negative binomial models tested whether age-expectations were consistently associated with health and well-being across racial/ethnic groups. Age-expectations differed by race/ethnicity, overall and for each subscale. African American participants expected the least age-related functional decline and Chinese American participants expected the most decline. Although African American participants expected less decline than Latino participants in unadjusted models, they had comparable expectations adjusting for education. Latino and African American participants consistently expected less decline than Korean and Chinese Americans. Acculturation was not consistently related to age-expectations among immigrant participants over and above ethnicity. Although some previously observed links between expectations and health replicated across racial/ethnic groups, in adjusted models age-expectations were only related to depression for Latino participants. With a growing racial/ethnic minority older population in the United States, it is important to note older adults' age-expectations differ by race/ethnicity. Moreover, expectation-health associations may not always generalize across diverse samples. © The Author 2017. Published by Oxford University Press on behalf of The Gerontological Society of America.

Regular physical activity (PA) plays an important role in improving and maintaining one's health, especially as one ages. Although many older Americans are aware of the benefits of regular PA, the majority do not participate in regular PA that meets recommended guidelines. The purpose of this study was to gain insight into the motivators, barriers, and beliefs regarding PA of independent-living older adults with easy access to fitness facilities. In this qualitative design, focus group interviews were used to explore the individual perceptions of physically active and inactive older adults regarding PA and exercise. Thirty-one older adults, over age 60 participated in focus group discussions regarding PA beliefs and behaviors. Groups were homogenous based on current PA behaviors. Demographic information was collected. Discussions were audiotaped and transcribed verbatim and deidentified. Two researchers independently coded for emergent themes. Interrater reliability was established (κ = 0.89). Peer review was used to further ensure trustworthiness and credibility. No significant differences were noted in age, body mass index, or educational levels between the physically active and inactive groups. Differences in perceptions were noted between the groups regarding the construct of PA, barriers to participation in regular PA, and the components of an ideal PA program. Physically inactive persons had much lower fitness expectations of a physically active older adult, more perceived barriers to regular PA, and required individual tailoring of a PA program if they were going to participate. In addition, inactive persons were intimidated by the fitness facilities and concerned about slowing others down in a group exercise setting. Both groups shared similar motivators to participate in PA, such as maintaining health and socialization; however, inactive persons also described PA as needing to be purposeful and fun. Physically inactive persons perceived themselves to be physically active, as their perception of PA was grounded in a social context. Although both groups shared some barriers to regular PA participation, physically active individuals developed strategies to overcome them. Issues relating to self-efficacy and stages of change need to be explored to address the individual perceptions and needs of inactive older adults if initiation or long-term adherence to a PA program is to be achieved.

Brain-derived neurotrophic factor (BDNF) serum basal levels is not affected by power training in mobility-limited older adults - A randomized controlled trial.

Brain-derived neurotrophic factor (BDNF) is a potential important factor involved in neuroplasticity, and may be a mediator for eliciting adaptations in neuromuscular function and physical function in older individuals following physical training. As power training taxes the neural system to a very high extent, it may be particularly effective in terms of eliciting increases in systemic BDNF levels. We examined the effects of 12weeks of power training on mature BDNF (mBDNF) and total BDNF (tBDNF) in mobility-limited older adults from the Healthy Ageing Network of Competence (HANC) study. We included 47 older men and women: n=22 in the training group (TG: progressive high intensity power training, 2 sessions per week; age 82.7±5.4years, 55% women) and n=25 in the control group (CG: no interventions; age 82.2±4.5years, 76% women). Following overnight fasting, basal serum levels of mBDNF and tBDNF were assessed (human ELISA kits) at baseline and post-intervention. At baseline, mBDNF and tBDNF levels were comparable in the two groups, TG and CG. Post-intervention, no significant within-group or between-group changes were observed in mBDNF or tBDNF. Moreover, when divided into responder tertiles based upon changes in mBDNF and tBDNF (i.e. decliners, maintainers, improvers), respectively, comparable findings were observed for TG and CG. Altogether, basal systemic levels of serum mBDNF and tBDNF are not affected in mobility-limited older adults following 12-weeks of power training, and do not appear to be a major mechanistic factor mediating neuroplasticity in mobility-limited older adults.

Old age-based discrimination is observed as the most tolerated prejudice in society and has also been witnessed in healthcare institutions. The aim of this study is to explore age-based discrimination in healthcare institutions as perceived by seniors and students of Medicine and Nursing. A multi-method study design, by involving a triangulation design. Participants and research context: A purposeful sample of individuals aged 65+ (n = 80) and medical and nursing students (n = 100) in the eastern region of Poland. Ethical considerations: Ethical approval of the research protocol was received from the Ethics Committee at the Medical University of Lublin. 'Old age' was perceived by groups of participants based on three themes: (a) positive, (b) negative and (c) neutral connotations. The negative connotations predominated. The beginning of old age was defined by the metric of age and described by showing the complexity of the ageing process involving subjective, objective and societal aspects. Experience of age discrimination in healthcare institutions was reported by 24 (30%) seniors and witnessed by 47 (47%) students surveyed and for both groups occurred mainly at the hospital level and by physicians. Only 48 students (48%) declared a willingness to work with the older people in the future, and barriers were reported at the personal and professional levels, and also in some visions of older people. The conceptualization of old age as reported by seniors and students mainly carried negative connotations, reflecting the profoundly based stereotypes within society regarding the older people. Seniors have reported being exposed to ageism and have witnessed ageism episodes in HCIs; also, students have faced ageism episodes during their clinical education. There is a need for ethical education within medical and nursing courses to shape positive attitudes towards the older people. A positive vision of ageing should be promoted not only among young people but also among adults and older people to avoid self-stereotyping of older people and seeing old age from negative perspective.

The aim of the study was to assess fatigue, depressive symptoms, and maternal confidence or satisfaction among older primiparae during the first month postpartum. The number of older Japanese primiparae has rapidly increased. Older primiparae are believed to be at high risk for puerperal morbidity. A multicentre prospective cohort study design was used. Data were examined from 2854 Japanese women who participated in a 6-month prospective cohort study conducted between May 2012 and September 2013. The women were classified into 4 groups based on maternal age and parity. All participants completed the Postnatal Accumulated Fatigue Scale, Japanese Edinburgh Postnatal Depression Scale, Postpartum Maternal Confidence Scale, and Postpartum Maternal Satisfaction Scale. Primiparae in all age groups were more severely fatigued and had a higher risk of postpartum depression than multiparous mothers during the first month postpartum. Older primiparae had significantly lower scores on maternal confidence and maternal satisfaction than the other 3 groups at 1 month postpartum. These findings suggest that postpartum nursing should focus on promoting adequate sleep, providing emotional support, and fostering the process of maternal role adaptation among older Japanese primiparae, particularly during the first postpartum month. © 2017 John Wiley & Sons Australia, Ltd.

Aging of the population is a growing problem in all developed societies. The older people need more health and social services, and their life quality in there is getting more and more important. The study aimed at determining the characteristics of non-verbal communication of the older people living in old people's homes (OPH). The sample consisted of 267 residents of the OPH, aged 65-96 years, and 267 caregivers from randomly selected twenty-seven OPH. Three types of non-verbal communication were observed and analysed using univariate and multivariate statistical methods. In face expressions and head movements about 75% older people looked at the eyes of their caregivers, and about 60% were looking around, while laughing or pressing the lips together was rarely noticed. The differences between genders were not statistically significant while statistically significant differences among different age groups was observed in dropping the eyes (p = 0.004) and smiling (0.008). In hand gestures and trunk movements, majority of older people most often moved forwards and clenched fingers, while most rarely they stroked and caressed their caregivers. The differences between genders were statistically significant in leaning on the table (p = 0.001), and changing the position on the chair (0.013). Statistically significant differences among age groups were registered in leaning forwards (p = 0.006) and pointing to the others (p = 0.036). In different modes of speaking and paralinguistic signs almost 75% older people spoke normally, about 70% kept silent, while they rarely quarrelled. The differences between genders were not statistically significant while statistically significant differences among age groups was observed in persuasive speaking (p = 0.007). The present study showed that older people in OPH in Slovenia communicated significantly less frequently with hand gestures and trunk movements than with face expressions and head movements or different modes of speaking and paralinguistic signs. The caregivers should be aware of this and pay a lot of attention to these two groups of non-verbal expressions. Their importance should be constantly emphasized during the educational process of all kinds of health-care professionals as well.

Medical students (MS) may develop ageist attitudes early in their training that may predict their future avoidance of caring for the elderly. This study sought to determine MS' patterns of explicit and implicit anti-aging bias, intent to practice with older people and using the quad model, the role of gender, race, and motivation-based differences. One hundred and three MS completed an online survey that included explicit and implicit measures. Explicit measures revealed a moderately positive perception of older people. Female medical students and those high in internal motivation showed lower anti-aging bias, and both were more likely to intend to practice with older people. Although the implicit measure revealed more negativity toward the elderly than the explicit measures, there were no group differences. However, using the quad model the authors identified gender, race, and motivation-based differences in controlled and automatic processes involved in anti-aging bias.

Changes in Health Perceptions among Older Grandparents Raising Adolescent Grandchildren.

2017-01-01

This research study explores health perceptions before and after becoming a primary caregiver among older grandparents raising adolescent grandchildren. Qualitative, in-depth face-to-face interviews were conducted with grandparents age 40 and older (N = 15) who were raising adolescent grandchildren age 12 and older. Most grandparents were female, had some college education, White/Non-Hispanic, were married, had an average age of 65 years, and reported never attending a grandparent support group. Before assuming the primary caregiver role, older grandparents described their physical health as good, filled with physical activity, and reasonably free of health conditions. After entering the primary caregiving role, older grandparents of adolescents described functional restrictions and visible changes in physical health requiring intensive medical interventions. In terms of mental health, older grandparent caregivers experienced anxiety, worry, depression, sadness, and frustration. These findings highlight the complex caregiving circumstances encountered by older grandparents raising adolescents and the need for health education and policy development to increase comprehensive supportive services targeting this population.

Although food hypersensitivity is a public health concern, its documentation among the elderly is limited. The current study aims to compare the prevalence and characteristics of food hypersensitivity among adolescent women between aged 18-24 with among older women >50 years of age. 660 female university students between the ages of 18 and 24 who volunteered were enrolled as adolescent subjects. 470 women >50 years old who visited the Health Care Centre of Kyoto Katsura Hospital for health check-ups were enrolled as the older subjects. A questionnaire created by ourselves asking the presence of food hypersensitivity, symptoms, causative food, personal or family history of other allergic disorders was distributed. The prevalence of food hypersensitivity was statistically similar between adolescent (8.2%) and older women (8.9%). Among them, only 24.1% of the adolescent women and 26.2% of the older women had been diagnosed by physicians as having food allergy. The main causative foods (fruits, shellfish and fish) and the manifestations relating to food hypersensitivity were almost identical between adolescent and older women. In both adolescent and older women, food hypersensitivity positive group showed significantly higher prevalence of personal or family history of allergic disorders than that in food hypersensitivity negative group. These data indicate that food hypersensitivity in older women should be given more attention because the prevalence of this condition was as common as that in adolescent women.

The aims of the present study were to: 1) gain insight into reasons for working beyond the statutory retirement age from older workers' perspectives, and 2) explore how the domains of the research framework Study on Transitions in Employment, Ability and Motivation (STREAM) can be applied to working beyond retirement age. A qualitative research design included individual interviews (n = 15) and three focus groups (n = 18 participants) conducted with older workers aged 65 years and older continuing in a paid job or self-employment. Interview participants were recruited from an existing STREAM cohort study. Focus group participants were recruited from companies and employment agencies. The data were subjected to thematic analysis. The most important motives for working beyond retirement age were maintaining daily routines and financial benefit. Good health and flexible work arrangements were mentioned as important preconditions. The themes emerging from the categorization of the motives and preconditions corresponded to the domains of health, work characteristics, skills and knowledge, and social and financial factors from the STREAM research framework. However, our analysis revealed one additional theme-purpose in life. This study offers important new insights into the various preconditions and motives that influence working beyond retirement age. In addition, the five domains of the STREAM research framework, including the additional domain of 'purpose in life', seem to be applicable to working beyond retirement age. This knowledge contributes to the development of work-related interventions that enhance older workers' motivation to prolong their working lives.

Age of renal transplants has been related to death, alloimmune response and graft outcome. We reviewed the influence of patient age on transplant outcome in three cohorts of patients transplanted in Spain during the 1990 s. Patient age was categorized into four groups (I, 18-40; II, 41-50; III, 51-60; and IV, > 60 years). Risks factors for acute rejection were evaluated by logistic regression adjusting for transplant centre and transplantation year, while a Cox proportional hazard model was employed for analysing patient and graft survival. Older patients had a higher death rate (I, 3.5%; II, 7.7%; III, 13.2%; and IV, 16.9%; P<0.001), but a lower standardized mortality index (I, 7.6; II, 7.0; III, 5.8; and IV, 4.1; P = 0.0019). Older patients had the lowest risk of acute rejection [odds ratio (OR) 0.79 and 95% confidence interval (CI) 0.66-0.97 for group II; OR 0.75 and 95% CI 0.62-0.91 for group III; OR 0.43 and 95% CI 0.33-0.56 for group IV). Death-censored graft survival was poorer in patients older than 60 years (relative risk 1.40; 95% CI 1.09-1.80), but this result was not explained by any combination of patient age with donor age, delayed graft function or immunosuppression. Patient age is a main determinant of transplant outcome. Although death rate is higher for older patients, standardized mortality was not. Thus, the efforts to reduce mortality should be also implemented in younger patients. Old patients have a low risk of acute rejection but a poorer death-censored graft survival. This last result was not explained by any controlled variable in our study.

Aging is associated with deterioration in health and well-being, but previous research suggests that this can be attenuated by maintaining group memberships and the valued social identities associated with them. In this regard, religious identification may be especially beneficial in helping individuals withstand the challenges of aging, partly because religious identity serves as a basis for a wider social network of other group memberships. This paper aims to examine relationships between religion (identification and group membership) and well-being among older adults. The contribution of having and maintaining multiple group memberships in mediating these relationships is assessed, and also compared to patterns associated with other group memberships (social and exercise). Study 1 (N = 42) surveyed older adults living in residential care homes in Canada, who completed measures of religious identity, other group memberships, and depression. Study 2 (N = 7021) longitudinally assessed older adults in the UK on similar measures, but with the addition of perceived physical health. In Study 1, religious identification was associated with fewer depressive symptoms, and membership in multiple groups mediated that relationship. However, no relationships between social or exercise groups and mental health were evident. Study 2 replicated these patterns, but additionally, maintaining multiple group memberships over time partially mediated the relationship between religious group membership and physical health. Together these findings suggest that religious social networks are an especially valuable source of social capital among older adults, supporting well-being directly and by promoting additional group memberships (including those that are non-religious).

Ageing and autobiographical memory for emotional and neutral events

We investigated age-related effects in recall of emotional and neutral autobiographical memories. Protocols were scored according to episodic and non-episodic detail categories using the Autobiographical Interview. Young adults recalled a greater number of episodic details compared to older adults, whereas older adults recalled more semantic details, replicating previous findings. Both young and older adults’ emotional memories contained more overall detail than neutral ones, with the enhancement from emotion-specific to episodic details, but this did not alter the effect of age group on the pattern of episodic and semantic details. However, the age effect on episodic details was attenuated for neutral autobiographical memories. The findings suggest that age differences for emotional autobiographical recollection might reflect a more general pattern of age-related changes in memory, with impaired recall of episodic components and relative sparing of semantic aspects of autobiographical memory in older adults when compared to young adults.

Views of the self and others at different ages: utility of repertory grid technique in detecting the positivity effect in aging.

PubMed

Williams, Ben D; Harter, Stephanie Lewis

2010-01-01

Socioemotional selectivity theory (Carstensen, 1995) posits a "positivity effect" in older adults, describing an increasing tendency to attend to, process, interpret, and remember events and others in life in a positive fashion as one ages. Drawing on personal construct theory, Viney (1993) observes increasing integration of constructions of self with others across the lifespan. The current study extends assessment of the positivity effect, integrating it with personal construct theory, by use of Repertory Grid (RepGrid) analysis. Consistent with the positivity effect, older adults (ages 54-86) described others more positively on RepGrid measures in comparison to younger adults (ages 18-25). Older adults also described the self as more similar to others and tended to describe the self more positively. The age groups did not differ in measures of psychological distress or well being with the exception of older adults describing more autonomy.

PAHA study: Psychological Active and Healthy Aging: psychological wellbeing, proactive attitude and happiness effects of whole-body vibration versus Multicomponent Training in aged women: study protocol for a randomized controlled trial

PubMed Central

2014-01-01

Background Evidence demonstrates that physical exercise and psychological wellbeing are closely interlinked, particularly in older-aged women. However, research investigating how different forms of exercise influence mental health in older-aged women is underdeveloped. Methods/Design A randomized controlled trial (N = 300) will assess the relative effectiveness of two different exercise programs (whole-body vibration and Multicomponent Training) for improving psychological wellbeing in older-aged women. The following outcomes will be assessed at three time points (that is, pre, post, and follow-up): psychological wellbeing, proactive attitude, quality of life, and happiness. Discussion Results will have important implications for preventing psychological and physiological disease in older-aged women and for managing health-related costs for this population group.

Age and Social Support Seeking: Understanding the Role of Perceived Social Costs to Others.

PubMed

Jiang, Li; Drolet, Aimee; Kim, Heejung S

2018-07-01

We examined age differences in the use of different types of social support and the reasons for these differences. We found that older adults (age 60+) seek explicit social support less compared with young adults (age 18-25), but there is no difference in implicit social support seeking. Concerns about the potential social costs of seeking explicit support mediate the age differences in explicit social support seeking. Whereas young adults view this strategy as conferring more benefits than costs, older adults have a more balanced view of the costs and benefits of explicit social support seeking. Older and young adults do not differ in perceptions of the relative costs versus benefits of implicit social support seeking. Finally, we found older adults benefit more from implicit (vs. explicit) social support emotionally than young adults, which further explains why age groups differ in their use of explicit versus implicit social support.

Older Adults' Online Dating Profiles and Successful Aging.

2016-12-01

This study examined how relevant Rowe and Kahn's three criteria of successful aging were to older adults' self-portrayals in online dating profiles: low probability of disease and disability, high functioning, and active life engagement. In this cross-sectional study, 320 online dating profiles of older adults were randomly selected and coded based on the criteria. Logistic regression analyses determined whether age, gender, and race/ethnicity predicted self-presentation. Few profiles were indicative of successful aging due to the low prevalence of the first two criteria; the third criterion, however, was identified in many profiles. Native Americans were significantly less likely than other ethnic groups to highlight the first two criteria. Younger age predicted presenting the first criterion. Women's presentation of the third criterion remained significantly high with age. The findings suggest that the criteria may be unimportant to older adults when seeking partners, or they may reflect the exclusivity of this construct.

Growth hormone is the major regulator of growth and body composition. Pulsatile GH secretion declines exponentially with age. Testosterone replacement is being increasingly offered to older men with age-related low testosterone. Testosterone administration has been shown to stimulate GH secretion. However, little is known about the effect of testosterone aromatization to estradiol on GH pulsatility and its impact on IGF-1 in older men. This randomized controlled proof-of-concept trial investigated the relative effects of testosterone and estradiol on GH pulsatility and IGF-1 in older men with low testosterone. Thirty-seven men, ≥65years with total testosterone <350ng/dL were randomized to 5g transdermal testosterone gel (TT), 1mg oral aromatase inhibitor (AI) or placebo daily for 12months. Primary outcome was deconvolution and approximate entropy analyses of pulsatile including basal and entropic modes of secretion performed at baseline and 3months. Secondary outcomes included IGF-1 evaluated at baseline, 3 and 6months. At 3months, mean GH and in IGF-1 were similar between the three groups. At 6months, IGF-1 significantly increased by Δ 15.3±10.3ng/ml in the TT-group compared to placebo (P=0.03). Both intervention groups significantly increased GH pulse frequency (TT-group, P=0.04; AI-group, P=0.05) compared to placebo. The GH secretory-burst mode (duration) significantly decreased in the TT-group (P=0.0018) compared to placebo while it remained unchanged in the AI-group (P=0.059). In older men, testosterone increases GH pulse frequency while the aromatization to estradiol is involved in the rise of IGF-1 levels. Copyright © 2017 Elsevier Inc. All rights reserved.

BACKGROUND: In a cross-sectional study examining late effects of pediatric sarcoma therapy, long-term survivors were evaluated on their activities of daily living (ADL) performance. PROCEDURE: Thirty-two persons with Ewing sarcoma family of tumors, rhabdomyosarcoma, and non-rhabdomysarcoma-soft tissue sarcoma enrolled an average of 17 years after treatment. Participants were evaluated using the Assessment of Motor and Process Skills (AMPS) [1], a standardized observational evaluation of ADL task performance. Means and 95% confidence intervals for ADL motor and ADL process ability measures were calculated for four groups: 1) sarcoma survivors, 2) “well” adults matched for age and gender, 3) “well” adults matched for gender that were 10 years older; and 4) “well” adults matched for gender that were 20 years older. RESULTS: ADL motor ability was significantly lower for sarcoma survivors than for the age and gender matched comparison group (p<0.05). There was no significant difference between ADL motor ability of sarcoma survivors and the comparison group 10 years older, but sarcoma survivors had significantly better ADL motor ability (p<0.05) than the oldest comparison group (20 years older). Sarcoma survivors had significantly worse ADL process ability than the age matched group (p<0.05). There was no difference in ADL process ability between the sarcoma survivors and comparison groups that were 10 and 20 years older. CONCLUSIONS: This first report of a clinical evaluation of ADL limitation in pediatric sarcoma survivors treated with intensive multimodal cancer therapy suggests that influences on performance of daily life activities are more common than previously reported.

Conceptual preparation mechanisms such as novel idea generation and selection from amongst competing alternatives are critical for language production and may contribute to age-related language deficits. This study investigated whether older adults show diminished idea generation and selection abilities, compared to younger adults. Twenty younger (18-35 years) and 20 older (60-80 years) adults completed two novel experimental tasks, an idea generation task and a selection task. Older participants were slower than younger participants overall on both tasks. Importantly, this difference was more pronounced for task conditions with greater demands on generation and selection. Older adults were also significantly reduced on a semantic, but not phonemic, word fluency task. Overall, the older group showed evidence of age-related decline specific to idea generation and selection ability. This has implications for the message formulation stage of propositional language decline in normal aging.

The impacts of community social capital on the life satisfaction of older adults in Hong Kong: the moderator role of intergenerational family capital.

This study examined the moderator role of intergenerational family capital on the relationship between community social capital and life satisfaction of older Chinese adults. The data were derived from a quota sampling of 372 older adults aged 60 and above, who were interviewed at four districts in Hong Kong in 2011. Multiple group analysis was employed to examine the proposed model. For the low family capital group, community social capital was found to be a significant predictor of life satisfaction, even when the well-known covariates were controlled. However, the association between community social capital and life satisfaction was statistically non-significant among the high family capital group. The findings highlighted the interplay between community social capital and intergenerational family capital, which supported community social capital replacement theory in understanding the mechanism linking social capital to life satisfaction in older age in a Chinese context. Community social capital can play a compensatory role in maintaining the mental health of older people. It is particularly important for older adults who lack family support and/or suffer from social isolation and loneliness in local communities.

Objective Psychomotor slowing has been documented in depression. The digital Clock Drawing Test (dCDT) provides: i) a novel technique to assess both cognitive and motor aspects of psychomotor speed within the same task and ii) the potential to uncover subtleties of behavior not previously detected with non-digitized modes of data collection. Method Using digitized pen technology in 106 participants grouped by Age (younger/older) and Affect (euthymic/unmedicated depressed), we recorded cognitive and motor output by capturing how the clock is drawn rather than focusing on the final product. We divided time to completion (TTC) for Command and Copy conditions of the dCDT into metrics of percent of drawing (%Ink) versus non-drawing (%Think) time. We also obtained composite z-scores of cognition, including attention/ information processing (AIP), to explore associations of %Ink and %Think times to cognitive and motor performance. Results Despite equivalent TTC, %Ink and %Think Command times (Copy n.s.) were significant (AgeXAffect interaction:p=.03)—younger depressed spent a smaller proportion of time drawing relative to thinking compared to the older depressed group. Command %Think time negatively correlated with AIP in the older depressed group (r=−.46;p=.02). Copy %Think time negatively correlated with AIP in the younger depressed (r=−.47;p=.03) and older euthymic groups (r=−.51;p=.01). Conclusion The dCDT differentiated aspects of psychomotor slowing in depression regardless of age, while dCDT/cognitive associates for younger adults with depression mimicked patterns of older euthymics.

The characteristics of self-referent beliefs about memory change with age. The relationship between beliefs and memory performance of three age groups of Japanese adults was investigated. The beliefs measured by the Personal Beliefs about Memory Instrument (Lineweaver & Hertzog, 1998) differed among the age groups and between sexes. In most scales, the ratings by middle-aged adults were as low as those by older adults, which were lower than those by young adults. Women perceived their memory abilities as lower than men's, with no interaction between age and sex, suggesting the difference remains across the lifespan. For middle-aged adults, the better they performed in cued-recall, free recall, and recognition, the lower they evaluated their memory self-efficacy, while few relationships were found for other groups. Our results suggest that cognitive beliefs change with age and that investigating the beliefs of the middle-aged adults is indispensable to elucidate the transition of beliefs.

2018-01-01

Drawing on job design theories and a conceptual framework of work-related goals and motivation in later adulthood, the aim of this paper is to explore how work-related and individual factors are separately and jointly related to psychological work ability and bridge employment intentions via late job mobility. The cross-sectional study is based on a sample of 171 older Spanish workers aged 45–65 and beyond. We differentiated between groups of older workers in mid career (45–55 years of age) and in their later careers (56 years and beyond). Our results confirm that task characteristics and, secondarily, knowledge characteristics are the most relevant factors in perceptions of psychological work ability among aged workers. Both age groups display a very marked personal mastery trait, which mediates the relationships between job characteristics and both psychological work ability and late job mobility intentions. The paper concludes with a discussion of theoretical and practical implications and suggestions for future research on the issues implied in the psychological adjustment of older workers in their mid and late careers.

Aging Influences the Neural Correlates of Lexical Decision but Not Automatic Semantic Priming

Andersen, Anders H.; Jicha, Greg A.; Smith, Charles D.

2009-01-01

Human behavioral data indicate that older adults are slower to perform lexical decisions (LDs) than young adults but show similar reaction time gains when these decisions are primed semantically. The present study explored the functional neuroanatomic bases of these frequently observed behavioral findings. Young and older groups completed unprimed and primed LD tasks while functional magnetic resonance imaging (fMRI) was recorded, using a fully randomized trial design paralleling those used in behavioral research. Results from the unprimed task found that age-related slowing of LD was associated with decreased activation in perceptual extrastriate regions and increased activation in regions associated with higher level linguistic processes, including prefrontal cortex. In contrast to these age-related changes in brain activation, the older group showed a preserved pattern of fMRI decreases in inferior temporal cortex when LD was primed semantically. These findings provide evidence that older adults’ LD abilities benefit from contexts that reduce the need for frontally mediated strategic processes and capitalize on the continued sensitivity of inferior temporal cortex to automatic semantic processes in aging.

Comparable Rest-related Promotion of Spatial Memory Consolidation in Younger and Older Adults

Craig, Michael; Wolbers, Thomas; Harris, Mathew A.; Hauff, Patrick; Della Sala, Sergio; Dewar, Michaela

2017-01-01

Flexible spatial navigation depends on cognitive mapping, a function that declines with increasing age. In young adults, a brief period of post-navigation rest promotes the consolidation/integration of spatial memories into accurate cognitive maps. We examined (1) whether rest promotes spatial memory consolidation/integration in older adults and (2) whether the magnitude of the rest benefit changes with increasing age. Young and older adults learned a route through a virtual environment, followed by a 10min delay comprising either wakeful rest or a perceptual task, and a subsequent cognitive mapping task, requiring the pointing to landmarks from different locations. Pointing accuracy was lower in the older than younger adults. However, there was a comparable rest-related enhancement in pointing accuracy in the two age groups. Together our findings suggest that (i) the age-related decline in cognitive mapping cannot be explained by increased consolidation interference in older adults, and (ii) as we grow older rest continues to support the consolidation/integration of spatial memories.

Community-acquired lower respiratory tract infections (LRTI) and pneumonia (CAP) are common causes of morbidity and mortality among those aged ≥65 years; a growing population in many countries. Detailed incidence estimates for these infections among older adults in the United Kingdom (UK) are lacking. We used electronic general practice records from the Clinical Practice Research Data link, linked to Hospital Episode Statistics inpatient data, to estimate incidence of community-acquired LRTI and CAP among UK older adults between April 1997-March 2011, by age, sex, region and deprivation quintile. Levels of antibiotic prescribing were also assessed. LRTI incidence increased with fluctuations over time, was higher in men than women aged ≥70 and increased with age from 92.21 episodes/1000 person-years (65-69 years) to 187.91/1000 (85-89 years). CAP incidence increased more markedly with age, from 2.81 to 21.81 episodes/1000 person-years respectively, and was higher among men. For both infection groups, increases over time were attenuated after age-standardisation, indicating that these rises were largely due to population aging. Rates among those in the most deprived quintile were around 70% higher than the least deprived and were generally higher in the North of England. GP antibiotic prescribing rates were high for LRTI but lower for CAP (mostly due to immediate hospitalisation). This is the first study to provide long-term detailed incidence estimates of community-acquired LRTI and CAP in UK older individuals, taking person-time at risk into account. The summary incidence commonly presented for the ≥65 age group considerably underestimates LRTI/CAP rates, particularly among older individuals within this group. Our methodology and findings are likely to be highly relevant to health planners and researchers in other countries with aging populations. PMID:24040394

New technology offers increased opportunities for weight control. However, it is not clear whether older people with less computer training can make use of this tool. Our objective was to examine how members above the age of 65 years performed in an internet-based behavioral weight loss program, compared to younger members. Data from members (n = 23,233) of an internet-based behavioral weight loss program were analyzed. We restricted our study to active participants accessing the weight club, during a 6-month period (n = 4,440). The number of logins, food intake, and weight records were examined. Participants were divided into age tertiles separately for men and women. The oldest tertile was further subdivided into two groups: above and below the age of 65 years. Participants aged 65 or older were more likely to remain active in the weight club for at least 6 months compared to younger age groups. They had the highest frequency of recordings of food intake and current weight. Among women, those older than 65 years had on average the highest percentage of weight loss (5.6 kg, 6.8%). Men above 65 years of age had the highest number of logins, on average 161 times during the 6-month period. Older participants are performing equally well or even better in an internet-based behavioral weight loss program than younger participants. Internet-based programs could be a promising and attractive option for older adults requiring assistance in losing weight. 2009 S. Karger AG, Basel.

The demand for long-term care for older adults has escalated sharply. A good policy dedicated to the welfare of older adults has improved their quality of life. The purpose of this study was to explore the social welfare utilization and needs of older adults and compare their differences among age groups, genders, and functional dependency levels. Three hundred eighty-four stratified, random-sampled Taiwanese community-dwelling older adults were recruited for this survey research. Participants rated their utilization of and needs for the 30 social welfare services provided by the government on a Likert-type scale. The most widely used and needed social welfare services by the older adults were senior monetary stipend and a subsidy for the national health insurance premium. Young-old, male, and functionally independent older adults had more knowledge of the social welfare services than their counterparts. While designing a comprehensive social welfare system, differing needs of different age groups, genders, and functional dependency levels should be taken into consideration.

Older adults display alterations in neural reflections of conflict-related processing. We examined response times (RTs), error rates, and event-related potential (ERP; N2 and P3 components) indices of conflict adaptation (i.e., congruency sequence effects) a cognitive control process wherein previous-trial congruency influences current-trial performance, along with post-error slowing, correct-related negativity (CRN), error-related negativity (ERN) and error positivity (Pe) amplitudes in 65 healthy older adults and 94 healthy younger adults. Older adults showed generalized slowing, had decreased post-error slowing, and committed more errors than younger adults. Both older and younger adults showed conflict adaptation effects; magnitude of conflict adaptation did not differ by age. N2 amplitudes were similar between groups; younger, but not older, adults showed conflict adaptation effects for P3 component amplitudes. CRN and Pe, but not ERN, amplitudes differed between groups. Data support generalized declines in cognitive control processes in older adults without specific deficits in conflict adaptation. Copyright © 2016 Elsevier B.V. All rights reserved.

Chronic low back pain (CLBP) is a highly prevalent and disabling musculoskeletal pain condition among older adults. Transcutaneous electrical nerve stimulation (TENS) is commonly used to treat CLBP, however, TENS response for older adults compared to younger adults is untested. In a dose-response study stratified by age, sixty participants with axial CLBP (20 young, 20 middle-aged, 20 older) received four 20-minute sessions of high frequency, high intensity TENS over a two to three-week period in a laboratory-controlled setting. Experimental measures of pain sensitivity (mechanical pressure pain detection threshold, PPT) and central pain excitability (phasic heat temporal summation, TS; heat aftersensations, AS) were assessed before and after TENS. Episodic or immediate axial CLBP relief was assessed after TENS via measures of resting pain, movement-evoked-pain, and self-reported disability. Cumulative or prolonged axial CLBP relief was assessed by comparing daily pain report across sessions. Independent of age, individuals experienced episodic increase in PPT and reduction in AS following TENS application. Similarly, all groups, on average, experienced episodic axial CLBP relief via improved resting pain, movement-evoked pain, and disability report. Under this design, no cumulative effect was observed as daily pain did not improve for any age group across the four sessions. However, older adults received higher TENS amplitude across all sessions in achieving similar TENS responses to younger adults. These findings suggest that older adults experience similar episodic axial CLBP relief as younger individuals following high frequency, high intensity TENS when higher dosage parameters are used.

Multiple studies have found neurofunctional changes in normal aging in a context of selective attention. Furthermore, many articles report intrahemispheric alteration in functional networks. However, little is known about age-related changes within the Ventral Attention Network (VAN), which underlies selective attention. The aim of this study is to examine age-related changes within the VAN, focusing on connectivity between its regions. Here we report our findings on the analysis of 27 participants' (13 younger and 14 older healthy adults) BOLD signals as well as their performance on a letter-matching task. We identified the VAN independently for both groups using spatial independent component analysis. Three main findings emerged: First, younger adults were faster and more accurate on the task. Second, older adults had greater connectivity among posterior regions (right temporoparietal junction, right superior parietal lobule, right middle temporal gyrus and left cerebellum crus I) than younger adults but lower connectivity among anterior regions (right anterior insula, right medial superior frontal gyrus and right middle frontal gyrus). Older adults also had more connectivity between anterior and posterior regions than younger adults. Finally, correlations between connectivity and response time on the task showed a trend toward connectivity in posterior regions for the older group and in anterior regions for the younger group. Thus, this study shows that intrahemispheric neurofunctional changes in aging also affect the VAN. The results suggest that, in contexts of selective attention, posterior regions increased in importance for older adults, while anterior regions had reduced centrality. Copyright © 2016 Elsevier B.V.

The application of allogeneic hematopoietic cell transplantation (allo-HCT) in non-Hodgkin lymphoma (NHL) patients ≥65 years in the United States is limited by lack of Medicare coverage for this indication. Using the Center for International Blood and Marrow Transplant Research (CIBMTR) database, we report allo-HCT outcomes of NHL patients aged ≥65 years (older cohort; n = 446) compared with a cohort of younger NHL patients aged 55-64 years (n = 1183). We identified 1629 NHL patients undergoing a first reduced-intensity conditioning (RIC) or nonmyeloablative conditioning allo-HCT from 2008 to 2015 in the United States. Cord blood or haploidentical transplants were excluded. The median age was 68 years (range 65-77) for the older cohort vs 60 years (range 55-64) in the younger cohort. The 4-year adjusted probabilities of nonrelapse mortality (NRM), relapse/progression (R/P), progression-free survival (PFS), and overall survival (OS) of the younger and older groups were 24% vs 30% ( P = .03), 41% vs 42% ( P = .82), 37% vs 31% ( P = .03), and 51% vs 46% ( P = .07), respectively. Using multivariate analysis, compared with the younger group, the older cohort was associated with increased NRM, but there was no difference between the 2 cohorts in terms of R/P, PFS, or OS. The most common cause of death was disease relapse in both groups. In NHL patients eligible for allo-HCT, there was no difference in OS between the 2 cohorts. Age alone should not determine allo-HCT eligibility in NHL, and Medicare should expand allo-HCT coverage to older adults.

We used fMRI to assess the neural correlates of autobiographical, semantic, and episodic memory retrieval in healthy young and older adults. Participants were tested with an event-related paradigm in which retrieval demand was the only factor varying between trials. A spatio-temporal partial least square analysis was conducted to identify the main patterns of activity characterizing the groups across conditions. We identified brain regions activated by all three memory conditions relative to a control condition. This pattern was expressed equally in both age groups and replicated previous findings obtained in a separate group of younger adults. We also identified regions whose activity differentiated among the different memory conditions. These patterns of differentiation were expressed less strongly in the older adults than in the young adults, a finding that was further confirmed by a barycentric discriminant analysis. This analysis showed an age-related dedifferentiation in autobiographical and episodic memory tasks but not in the semantic memory task or the control condition. These findings suggest that the activation of a common memory retrieval network is maintained with age, whereas the specific aspects of brain activity that differ with memory content are more vulnerable and less selectively engaged in older adults. Our results provide a potential neural mechanism for the well-known age differences in episodic/autobiographical memory, and preserved semantic memory, observed when older adults are compared with younger adults.

Successful physiological aging and episodic memory: a brain stimulation study.

Functional neuroimaging studies have shown that younger adults tend to asymmetrically recruit specific regions of an hemisphere in an episodic memory task (Hemispheric Encoding Retrieval Asymmetry-HERA model). In older adults, this hemispheric asymmetry is generally reduced as suggested by the Hemispheric Asymmetry Reduction for OLDer Adults-HAROLD-model. Recent works suggest that while low-performing older adults do not show this reduced asymmetry, high-performing older adults counteract age-related neural decline through a plastic reorganization of cerebral networks that results in reduced functional asymmetry. However, the issue of whether high- and low-performing older adults show different degrees of asymmetry and the relevance of this process for counteracting aging have not been clarified. We used transcranial magnetic stimulation (TMS) to transiently interfere with the function of the dorsolateral prefrontal cortex (DLPFC) during encoding or retrieval of associated and non-associated word pairs. A group of healthy older adults was studied during encoding and retrieval of word pairs. The subjects were divided in two subgroups according to their experimental performance (i.e., high- and low-performing). TMS effects on retrieval differed according to the subject's subgroup. In particular, the predominance of left vs. right DLPFC effects during encoding, predicted by the HERA model, was observed only in low-performing older adults, while the asymmetry reduction predicted by the HAROLD model was selectively shown for the high-performing group. The present data confirm that older adults with higher memory performance show less prefrontal asymmetry as an efficient strategy to counteract age-related memory decline.

To examine diary-based, laboratory-based, and actigraphic measures of sleep in a group of healthy older women and men (> or =75 years of age) without sleep/wake complaints and to describe sleep characteristics which may be correlates of health-related quality of life in old age. Cross-sectional, descriptive study. University-based sleep and chronobiology program. None. Sixty-four older adults (30 women, 34 men; mean age 79). We used diary-, actigraphic-, and laboratory-based measures of sleep, health-related quality of life, mental health, social support, and coping strategies. We used two-group t-tests to compare baseline demographic and clinical measures between men and women, followed by ANOVA on selected EEG measures to examine first-night effects as evidence of physiological adaptability. Finally, we examined correlations between measure of sleep and health-related quality of life. We observed that healthy men and women aged 75 and older can experience satisfactory nocturnal sleep quality and daytime alertness, especially as reflected in self-report and diary-based measures. Polysomnography (psg) suggested the presence of a first-night effect, especially in men, consistent with continued normal adaptability in this cohort of healthy older adults. Continuity and depth of sleep in older women were superior to that of men. Diary-based measures of sleep quality (but not psg measures) correlated positively (small to moderate effect sizes) with physical and mental health-related quality of life. Sleep quality and daytime alertness in late life may be more important aspects of successful aging than previously appreciated. Good sleep may be a marker of good functioning across a variety of domains in old age. Our observations suggest the need to study interventions which protect sleep quality in older adults to determine if doing so fosters continued successful aging.

The aim of the study was to investigate the behaviours, cognitive processes and practice activities of 12 English youth professional soccer coaches across 6 different age groups. Systematic observation data were collected using a modified version of the Coach Analysis and Intervention System which provided a detailed analysis of coaching behaviours performed during practice. Interpretive interviews were then triangulated with the behavioural data to identify the cognitive processes underlying the behaviours performed. The behavioural results showed that the coaches of the younger age groups used more instruction and the coaches of the older age groups used more divergent questioning and significantly more total feedback and punitive behaviours. The coaches of the younger age groups used more training form activities than the coaches of the older age groups who used more playing form activities. However, the interviews revealed that instead of the age of athletes' directly affecting the cognitive process of coaches it was in fact the coaches underlying beliefs about coaching, their previous experiences and perceived pressures from the context that determined the behaviours performed.

Older adults with panic disorder and agoraphobia (PDA) are underdiagnosed and undertreated, while studies of cognitive-behavioral therapy (CBT) are lacking. This study compares the effectiveness of CBT for PDA in younger and older adults. A total of 172 patients with PDA (DSM-IV) received manualized CBT. Primary outcome measures were avoidance behavior (Mobility Inventory Avoidance scale) and agoraphobic cognitions (Agoraphobic Cognitions Questionnaire), with values of the younger (18-60 years) and older (≥ 60 years) patients being compared using mixed linear models adjusted for baseline inequalities, and predictive effects of chronological age, age at PDA onset and duration of illness (DOI) being examined using multiple linear regressions. Attrition rates were 2/31 (6%) for the over-60s and 31/141 (22%) for the under-60s group (χ(2) = 3.43, df = 1, P = .06). Patients in both age groups improved on all outcome measures with moderate-to-large effect sizes. Avoidance behavior had improved significantly more in the 60+ group (F = 4.52, df = 1,134, P = .035), with agoraphobic cognitions showing no age-related differences. Baseline severity of agoraphobic avoidance and agoraphobic cognitions were the most salient predictors of outcome (range standardized betas 0.59 through 0.76, all P-values < .001). Apart from a superior reduction of agoraphobic avoidance in the 60+ participants (β = -0.30, P = .037), chronological age was not related to outcome, while in the older patients higher chronological age, late-onset type and short DOI were linked to superior improvement of agoraphobic avoidance. CBT appears feasible for 60+ PDA-patients, yielding outcomes that are similar and sometimes even superior to those obtained in younger patients. © 2014 Wiley Periodicals, Inc.

Introduction Individuals with neurodevelopmental disorders have been observed to show accelerated cognitive aging or even dementia as early as 30 and 40 years of age. Memory deficits are an important component of age-related cognitive loss. Methods In this study, we investigated prospective memory, which is often impaired in aging, in a group of 32 adults with spina bifida meningomyelocele (SBM), including members of the oldest living cohort successfully treated with shunts to divert excess cerebrospinal fluid, ventriculomegaly, and hydrocephalus, who are now around 50 years of age. Seventeen typically developing adults provided a comparison group. Results The SBM and comparison groups differed in the prospective memory total score as well as in both time-based and event-based subscores. Prospective memory was impaired in both older and younger individuals with SBM. However, the percentage of individuals with impaired or poor prospective memory was three times higher in the older SBM group than in the younger SBM group. The results are considered in relation to specific features of the complex brain reorganization in SBM. PMID:20393850

Although engagement of medial prefrontal cortex (MPFC) underlies self-referencing of information for younger and older adults, the region has not consistently been implicated across age groups for the encoding of self-referenced information. We sought to determine whether making judgments about others as well as the self influenced findings in the previous study. During an fMRI session, younger and older adults encoded adjectives using only a self-reference task. For items later remembered compared to those later forgotten, both age groups robustly recruited medial prefrontal cortex, indicating common neural regions support encoding across younger and older adults when participants make only self-reference judgments. Focal age differences emerged in regions related to emotional processing and cognitive control, though these differences are more limited than in tasks in which judgments also are made about others. We conclude that making judgments about another person differently affects the ways that younger and older adults make judgments about the self, with results of a follow-up behavioral study supporting this interpretation.

Objectives. We estimated dementia incidence rates, life expectancies with and without dementia, and percentage of total life expectancy without dementia. Methods. We studied 3605 members of Group Health (Seattle, WA) aged 65 years or older who did not have dementia at enrollment to the Adult Changes in Thought study between 1994 and 2008. We estimated incidence rates of Alzheimer’s disease and dementia, as well as life expectancies with and without dementia, defined as the average number of years one is expected to live with and without dementia, and percentage of total life expectancy without dementia. Results. Dementia incidence increased through ages 85 to 89 years (74.2 cases per 1000 person-years) and 90 years or older (105 cases per 1000 person-years). Life expectancy without dementia and percentage of total life expectancy without dementia decreased with age. Life expectancy with dementia was longer in women and people with at least a college degree. Percentage of total life expectancy without dementia was greater in younger age groups, men, and those with more education. Conclusions. Efforts to delay onset of dementia, if successful, would likely benefit older adults of all ages. PMID:25033130

Age Differences in Emotion Regulation Choice: Older Adults Use Distraction Less Than Younger Adults in High-Intensity Positive Contexts.

Previous research demonstrates that younger and older adults prefer distraction over engagement (reappraisal) when regulating high-intensity negative emotion. Older adults also demonstrate a greater bias for positive over negative information in attention and memory compared with younger adults. In this study, we investigated whether emotion regulation choice preferences may differ as a function of stimulus valence with age. The effect of stimulus intensity on negative and positive emotion regulation strategy preferences was investigated in younger and older men. Participants indicated whether they favored distraction or reappraisal to attenuate emotional reactions to negative and positive images that varied in intensity. Men in both age-groups preferred distraction over reappraisal when regulating high-intensity emotion. As no age-related strategic differences were found in negative emotion regulation preferences, older men chose to distract less from high-intensity positive images than did younger men. Older men demonstrated greater engagement with highly positive emotional contexts than did younger men. Thus, age differences in emotion regulation goals when faced with intense emotional stimuli depend on the valence of the emotional stimuli.

Neural Mechanisms of Reading Facial Emotions in Young and Older Adults

The ability to read and appropriately respond to emotions in others is central for successful social interaction. Young and older adults are better at identifying positive than negative facial expressions and also expressions of young than older faces. Little, however, is known about the neural processes associated with reading different emotions, particularly in faces of different ages, in samples of young and older adults. During fMRI, young and older participants identified expressions in happy, neutral, and angry young and older faces. The results suggest a functional dissociation of ventromedial prefrontal cortex (vmPFC) and dorsomedial prefrontal cortex (dmPFC) in reading facial emotions that is largely comparable in young and older adults: Both age groups showed greater vmPFC activity to happy compared to angry or neutral faces, which was positively correlated with expression identification for happy compared to angry faces. In contrast, both age groups showed greater activity in dmPFC to neutral or angry than happy faces which was negatively correlated with expression identification for neutral compared to happy faces. A similar region of dmPFC showed greater activity for older than young faces, but no brain-behavior correlations. Greater vmPFC activity in the present study may reflect greater affective processing involved in reading happy compared to neutral or angry faces. Greater dmPFC activity may reflect more cognitive control involved in decoding and/or regulating negative emotions associated with neutral or angry than happy, and older than young, faces.

Loneliness is a common experience among older people that is associated with health risks and negative well-being. As a psychological phenomenon, it has typically been defined in Western research literature as the discrepancy between desired and actual interpersonal relations. In our qualitative study in Hong Kong, we offer insight into ageing and loneliness in an urban environment of the non-Western world and propose to reconceptualise loneliness by exploring older people’s experience of alienation at the societal level as an important but often neglected dimension of their loneliness. Thirty-seven community-dwelling, Chinese adults aged 65 and above were interviewed in focus groups and their accounts analysed and interpreted using a phenomenological approach. Findings revealed that focus group participants perceived insufficient care for older people, a growing distance between themselves and society, and their disintegrating identity in society to be primary sources of societal alienation. In response, older people adopted a more passive lifestyle, attributed marginalisation and inequality to old age, and developed negative feelings including unease towards ageing, vulnerability and helplessness, and anger. The emergence of these key components and underlying themes of societal alienation illuminated neglected facets of the psychological phenomenon of loneliness and highlighted new implications for policy, practice, and research from a societal perspective to address older people’s loneliness in urban settings.

Objectives: to examine perceived age discrimination in a large representative sample of older adults in England. Methods: this cross-sectional study of over 7,500 individuals used data from the fifth wave of the English Longitudinal Study of Ageing (ELSA), a longitudinal cohort study of men and women aged 52 years and older in England. Wave 5 asked respondents about the frequency of five everyday discriminatory situations. Participants who attributed any experiences of discrimination to their age were treated as cases of perceived age discrimination. Multivariable logistic regression analysis was used to estimate the odds ratios of experiencing perceived age discrimination in relation to selected sociodemographic factors. Results: approximately a third (33.3%) of all respondents experienced age discrimination, rising to 36.8% in those aged 65 and over. Perceived age discrimination was associated with older age, higher education, lower levels of household wealth and being retired or not in employment. The correlates of age discrimination across the five discriminatory situations were similar. Conclusion: understanding age discrimination is vital if we are to develop appropriate policies and to target future interventions effectively. These findings highlight the scale of the challenge of age discrimination for older adults in England and illustrate that those groups are particularly vulnerable to this form of discrimination.
