    This article reports on gender ratio, age of diagnosis and the duration of assessment procedures in autism spectrum disorder diagnosis in a national study which included all types of clinical services for children and adults. Findings are reported from a retrospective case note analysis undertaken with a representative sample of 150 Scottish children and adults recently diagnosed with autism spectrum disorder. The study reports key findings that the gender ratio in this consecutively referred cohort is lower than anticipated in some age groups and reduces with increasing age. The gender ratio in children, together with the significant difference in the mean age of referral and diagnosis for girls compared to boys, adds evidence of delayed recognition of autism spectrum disorder in younger girls. There was no significant difference in duration of assessment for males and females suggesting that delays in diagnosis of females occur prior to referral for assessment. Implications for practice and research are considered. PMID:26825959

    Background: Non-medical utilization of pre-implantation genetic diagnosis (PGD), like sex selection, is increasing, therefore it is necessary to follow-up the health and outcome of fertilization and newborn's birth followed PGD. The aim of this study was to evaluate the outcome of fertilization after sex selection by PGD and the relation between the age of parents and the outcome of fertilization. Materials and Methods: This was a retrospective descriptive correlative study conducted on 218 couples in Isfahan. Samples were selected through convenience sampling. The rate of chemical and clinical pregnancy and abortion, the frequency of success in achieving the desired sex, and the mean of gestational age and weight of newborns were gathered through reviewing medical files and phone interviews. Data was analyzed using independent t test and Pearson correlation test. Results: The rate of chemical and clinical pregnancy was 30.7% and 30.3% respectively, the rate of abortion was 26.9%, the frequency of success in achieving the desired sex was 100%, and the mean of gestational age and weight of newborns was 3260 (616) kg and 37.7 (2.07) weeks respectively. There was no significant relation between the age of parents and the rate of abortion, the rate of chemical and clinical pregnancy and newborn's gestational weight. But there was a significant relation between the age of men and gestational age of newborns (P = 0.04). Conclusions: PGD method was 100% successful in achieving the desired sex, but relatively high rate of abortion could indicate the effect of PGD on the embryo development process. PMID:26793251

    Demographic aspects of gender differences in aging characteristics for Russian Federation and Saint-Petersburg, the greatest non-metropolitan Russian megalopolis, for the period 1990-2009 have been considered. Differences in the number and proportions of the elderly in the male and female populations, gender gap in life expectancies, gender differences in aging indicators which take account of remaining years of life have been examined. Results of the study demonstrate significant gender differences in aging characteristics. Gender imbalance should be taken into account when elaboration effective demographic, social and economic policies. PMID:25306653

    As a concept in gerontology, gender appears as lists of traits learned through socialization when theorized at all. I argue for a framework that theorizes the intersections of relations of gender inequality with those of age. This framework holds that men and women gain resources and bear responsibilities, in relation to one another, by virtue of mundane categorization into naturalized stratified groups. Current research shows that this approach allows explanation of gender differences, which appear in many reports but which usually go untheorized, as responses to social inequality. I illustrate applications to research and practice in relation to three areas of old age experiences: financial security, spousal care work, and health. Throughout, I discuss implications of focusing on inequality to enhance our abilities to engage in effective research, practice, and policy for older people, women and men alike. For instance, an understanding of the gender division of labor and workplace discrimination makes clear that financial status in later life cannot be reduced to individual choices concerning paid labor or retirement planning. And understanding that people orient their behaviors to gender ideals allows us to see that men and women perform spousal care in similar and different ways that require varied responses from practitioners; it also reveals contexts in which men engage in positive health behaviors. Finally, I argue that gerontologists interested in facilitating favorable outcomes for old people should consider research and practice that would disrupt, not reinforce, the bases of gender inequalities in later life.

    Results from three studies relevant to a model of food cognition based on the evaluative dimensions pleasure, health, and convenience are reported. In the first study, discriminant analyses of the evaluative ratings (n = 248) of 35 meals and snacks yielded significant gender and age differences on the pleasure and health dimensions. Separate factor analyses of the pleasure and health ratings revealed that males and females grouped foods differently on these criteria. The factor analysis of convenience ratings suggested that males and females perceive the meaning of convenience differently. In the second study, 336 college students rated 27 meals on the three evaluative dimensions and also indicated their preferences for each meal. Multiple regression analyses showed that preferences could be significantly predicted, and other results showed that as compared to males, females give higher health, pleasure and convenience ratings to healthy meals. The third study employed a modified free association technique to investigate gender and age differences in the meanings of nine familiar foods. Data from 96 males and females aged 18 to 86 revealed a substantial variety of significant age and gender differences for specific foods. It is suggested that taken together, these results indicate important cognitive and affective sources for gender and age-related food attitudes. PMID:8452376

  9. Age-related eye disease and gender.

    2016-01-01

    Worldwide, the prevalence of moderate to severe visual impairment and blindness is 285 millions, with 65% of visually impaired and 82% of all blind people being 50 years and older. Meta-analyses have shown that two out of three blind people are women, a gender discrepancy that holds true for both developed and developing countries. Cataract accounts for more than half of all blindness globally and gender inequity in access to cataract surgery is the major cause of the higher prevalence of blindness in women. In addition to gender differences in cataract surgical coverage, population-based studies on the prevalence of lens opacities indicate that women have a higher risk of developing cataract. Laboratory as well as epidemiologic studies suggest that estrogen may confer antioxidative protection against cataractogenesis, but the withdrawal effect of estrogen in menopause leads to increased risk of cataract in women. For the other major age-related eye diseases; glaucoma, age-related macular degeneration (AMD) and diabetic retinopathy, data are inconclusive. Due to anatomic factors, angle closure glaucoma is more common in women, whereas the dominating glaucoma type; primary open-angle glaucoma (POAG), is more prevalent in men. Diabetic retinopathy also has a male predominance and vascular/circulatory factors have been implied both in diabetic retinopathy and in POAG. For AMD, data on gender differences are conflicting although some studies indicate increased prevalence of drusen and neovascular AMD in women. To conclude, both biologic and socioeconomic factors must be considered when investigating causes of gender differences in the prevalence of age-related eye disease. PMID:26508081

    The purpose of this study was to investigate the relationships among gender, age, and intellectual development. Random samples of 70 females and 70 males were selected with each sex group equally divided into a low-age and a high-age group. The low-age group ranged in age from 16.25 years to 16.75 years and the high-age group from 16.76 years to 17.25 years. The Piaget tasks selected to measure cognitive development were: Conservation of Volume, Separation of Variables, and Equilibrium in the Balance and Combination of Colorless Chemical Liquids. Data from this research produced these findings: (1) males demonstrate a higher level of intellectual development than females, (2) males mature intellectually earlier than females, (3) the value of the conservation of volume task as a component of a battery of formal tasks depends upon whether the decisions are to be made on the basis of the total-task results or on individual task performance, and (4) there appear to be factors other than age and gender that are related to the development of formal operational reasoning. These investigators hypothesize that experiences is another important factor.

    Preimplantation genetic diagnosis (PGD) of gender selection for non medical reasons has been considered an unethical procedure by several authors and agencies in the Western society on the basis of disrupting the sex ratio, being discriminatory againsts women and disposal of normal embryos of the non desired gender. In this study, the analysis of a large series of PGD procedures for gender selection from a wide geographical area in the United States, shows that in general there is no deviation in preference towards any specific gender except for a preference of males in some ethnic populations of Chinese, Indian and Middle Eastern origin that represent a small percentage of the US population. In cases where only normal embryos of the non-desired gender are available, 45.5% of the couples elect to cancel the transfer, while 54.5% of them are open to have transferred embryos of the non-desired gender, this fact being strongly linked to cultural and ethnical background of the parents. In addition this study adds some evidence to the proposition that in couples with previous children of a given gender there is no biological predisposition towards producing embryos of that same gender. Based on these facts, it seems that objections to gender selection formulated by ethics committees and scientific societies are not well-founded.

    Gender identity disorder, or transsexualism as it is more commonly known, is a highly complex clinical entity. It is an identifiable and incapacitating disease which can be diagnosed and successfully treated by reassignment surgery. The diagnosis of gender identity disorder can be a difficult process. Transsexual patients will have to undergo extensive psychiatric assessment. The authors review the development of nosology of transsexualism. The current classification systems, symptoms and diagnostic features of gender identity disorders are discussed. The article also discusses differential diagnostic features, like intersex states, psychosis, transvestitism, autogynephilia, gynandromorphophilia, and self-amputation. The authors also discuss the problem of comorbidity, as well. PMID:18956626

    The understanding of sociolinguistic variation is growing rapidly, but basic gaps still remain. Whether some languages or dialects are spoken faster or slower than others constitutes such a gap. Speech tempo is interconnected with social, physical and psychological markings of speech. This study examines regional variation in articulation rate and its manifestations across speaker age, gender and speaking situations (reading vs. free conversation). The results of an experimental investigation show that articulation rate differs significantly between two regional varieties of American English examined here. A group of Northern speakers (from Wisconsin) spoke significantly faster than a group of Southern speakers (from North Carolina). With regard to age and gender, young adults read faster than older adults in both regions; in free speech, only Northern young adults spoke faster than older adults. Effects of gender were smaller and less consistent; men generally spoke slightly faster than women. As the body of work on the sociophonetics of American English continues to grow in scope and depth, we argue that it is important to include fundamental phonetic information as part of our catalog of regional differences and patterns of change in American English.

    Using a convenience sample and survey research methods, the authors seek to better understand how perspectives on gender are shaped by individuals' age, level of education and gender. Study participants responded in writing to scenarios and survey questions, revealing their personal views on gender as an identity category and as a marker in the social hierarchy. Analysis indicated that there were differences between male and female views on these dimensions of gender, and that age and educational levels were also influential. While younger respondents from both genders demonstrated flexibility in their definitions of gender and expressed strong support for gender equality, they were noticeably lacking in their knowledge of the historical context of gender relations and did not show the skills required to realise their ideals of gender equality, especially when compared to older respondents of both genders with higher levels of educational attainment.

    Gender differences in autobiographical memory emerge in some data collection paradigms and not others. The present study included an extensive analysis of gender differences in autobiographical narratives. Data were collected from 196 participants, evenly split by gender and by age group (emerging adults, ages 18-29, and young adults, ages 30-40). Each participant reported four narratives, including an event that had occurred in the last 2 years, a high point, a low point, and a self-defining memory. Additionally, all participants completed self-report measures of masculine and feminine gender typicality. The narratives were coded along six dimensions-namely coherence, connectedness, agency, affect, factual elaboration, and interpretive elaboration. The results indicated that females expressed more affect, connection, and factual elaboration than males across all narratives, and that feminine typicality predicted increased connectedness in narratives. Masculine typicality predicted higher agency, lower connectedness, and lower affect, but only for some narratives and not others. These findings support an approach that views autobiographical reminiscing as a feminine-typed activity and that identifies gender differences as being linked to categorical gender, but also to one's feminine gender typicality, whereas the influences of masculine gender typicality were more context-dependent. We suggest that implicit gendered socialization and more explicit gender typicality each contribute to gendered autobiographies. PMID:27068433

    This study investigated the participation and performance trends as well as the age and gender interaction at the Olympic distance 'Zürich Triathlon' (1.5 km swim, 40 km cycle and 10 km run) from 2000 to 2010 in 7,939 total finishers (1,666 females and 6,273 males). Female triathletes aged from 40 to 54 years significantly (P < 0.05) increased their participation while the participation of younger females and males remained stable. Males of 50-54 years of age and females of 45-49 years of age improved their total race time. For elite top five overall triathletes, mean gender differences in swimming, cycling, running and overall race time were 15.2 ± 4.6%, 13.4 ± 2.3%, 17.1 ± 2.5%, and 14.8 ± 1.8%, respectively. For both elite and age group athletes, the gender difference in cycling time was significantly (P <0.001) lower than for swimming and running. The gender difference in overall Olympic distance triathlon performance increased after the age of 35 years, which appeared earlier compared to long distance triathlon as suggested by previous studies. Future investigations should compare gender difference in performance for different endurance events across age to confirm a possible effect of exercise duration on gender difference with advancing age.

    Study Objectives: To examine the impact of gender in narcoleptic patients on timeliness of diagnosis, symptomology, and health and lifestyle impairment Methods: This is a cross-sectional study of 109 consecutive patients (68 women) with newly diagnosed narcolepsy with and without cataplexy, from a University sleep disorders center. Consecutive patients were administered an 8-page questionnaire at the time of their diagnosis regarding sleep habits, medications, and medical conditions, lifestyle impairments, as well as details regarding narcolepsy-related symptoms. Results: Men and women presented with remarkably similar narcolepsy related symptoms, yet women were more likely to be delayed in diagnosis; 85% of men were likely to be diagnosed by 16 years after symptom onset, compared to 28 years in women. More women were likely to remain undiagnosed at any given time point after symptom onset (hazard ratio for diagnosis of men compared to women 1.53; 95% CI 1.01-2.32; p = 0.04). Men and women reported similar degree of subjective sleepiness as measured by the Epworth Sleepiness Scale (mean 16.2 ± 4.5; p = 0.18), though women demonstrated significantly more severe objective sleepiness on multiple sleep latency testing (MSLT) (mean sleep latency in women = 5.4 min (± 4.1), in men 7.4 min (± 3.5); p = 0.03). Despite being more objectively sleepy, women were less likely to report lifestyle impairments in the areas of personal relationships (71% men, 44% women, p = 0.01) and physical activity (36% men, 16% women, p = 0.02), but were also more likely to self-medicate with caffeine (63.4% men, 82.4% women; p = 0.03). Conclusions: Narcolepsy impacts men and women's health and lifestyle differently, and may cause delays diagnosis for women. Citation: Won C; Mahmoudi M; Qin L; Purvis T; Mathur A; Mohsenin V.

    Verbal fluency is a basic function of language that refers to the ability to produce fluent speech. Despite being an essentially linguistic function, its measurements are also used to evaluate executive aspects of verbal behavior. Performance in verbal fluency (VF) tasks varies according to age, education, and cognitive development. Neurodevelopmental disorders that affect the functioning of frontal areas tend to cause lower performance in VF tasks. Despite the relative consensus that has been reached in terms of the use of VF tasks for the diagnosis of dyslexia and attention-deficit/hyperactivity disorder, few studies have considered regional variations in Brazil. The present study sought to provide normative data on VF tasks in children by considering gender, age, education, and geopolitical region of origin with auxiliary purposes in neuropsychological diagnosis of disorders that occur with executive changes The study included 298 participants, 7-10 years of age of both genders, who performed three letter fluency tasks and three category fluency tasks. The data were subjected to correlational and variance analyses, with age and gender as factors. No effect of gender on the children's performance was found. However, significant differences between age groups were observed, with better performance in letter tasks in older children and better performance in letter tasks compared with category tasks. Significant regional differences in performance on the letter VF task were observed. These results reinforce the importance of regional normative data in countries with high regional cultural variations, such as Brazil. PMID:27242598

    Affective computing aims at the detection of users’ mental states, in particular, emotions and dispositions during human-computer interactions. Detection can be achieved by measuring multimodal signals, namely, speech, facial expressions and/or psychobiology. Over the past years, one major approach was to identify the best features for each signal using different classification methods. Although this is of high priority, other subject-specific variables should not be neglected. In our study, we analyzed the effect of gender, age, personality and gender roles on the extracted psychobiological features (derived from skin conductance level, facial electromyography and heart rate variability) as well as the influence on the classification results. In an experimental human-computer interaction, five different affective states with picture material from the International Affective Picture System and ULM pictures were induced. A total of 127 subjects participated in the study. Among all potentially influencing variables (gender has been reported to be influential), age was the only variable that correlated significantly with psychobiological responses. In summary, the conducted classification processes resulted in 20% classification accuracy differences according to age and gender, especially when comparing the neutral condition with four other affective states. We suggest taking age and gender specifically into account for future studies in affective computing, as these may lead to an improvement of emotion recognition accuracy. PMID:26939129

    Clinical initiatives have aimed to reduce the age at ASD diagnosis in the UK. This study investigated whether the median age at diagnosis in childhood has reduced in recent years, and identified the factors associated with earlier diagnosis in the UK. Data on 2134 children with ASD came from two large family databases. Results showed that the age of ASD diagnosis has not decreased. The median age of diagnosis of all ASDs was 55 months. Factors associated with earlier age of diagnosis were autism diagnosis (compared with other ASD), language regression, language delay, lower socioeconomic status, and greater degree of support required. Effective clinical strategies are needed to identify children with characteristics that have in the past delayed ASD diagnosis. PMID:27032954

    Research shows that abuse in adolescence can start early and current literature regarding gender differences in Teen Relationship Violence (TRV) is inconsistent. Age and Gender differences in TRV were examined. Measures assessing TRV and its correlates were completed by 231 teens from 7th, 9th, and 11th grade classes. A 2 (gender) by 3 (grade) multivariate analysis of variance revealed significant effects for grade and gender indicating that 7th graders have lower perpetration and victimization of TRV, less anger control, and fewer positive conflict resolution behaviors than 9th and 11th graders. Furthermore, girls perpetrate more physical and emotional abuse while boys perpetrate more sexual abuse. Results have implications for timing and content of prevention programs addressing dating violence in adolescence. PMID:26989341

    A meta-analysis was conducted on 27 studies addressing gender differences on 31 indices of sleeping behavior of persons 58 years of age and older. All pertinent, original research articles published in the United States in the last decade were included. New findings were compared with summaries from earlier studies to complete a picture of current knowledge. Effect sizes were calculated for 23 variables related to sleep continuity, architecture, and pathology; and effect sizes were averaged across studies. Gender difference effect sizes were small to moderate, with men tending to show more objective changes from the patterns of healthy youthful sleep. Results underscore the importance of health providers having an understanding of gender and age in relation to sleep. Findings suggest the need to protect the lighter, more fragile sleep of the elderly; to encourage regularity in sleep patterns; and to use sleep-inducing medications with caution. PMID:2287853

    Background Lifestyle-related diseases, including diabetes, cardiovascular disease, and some cancers represent the greatest global health threat. Greater insight into health needs and beliefs, using broad community samples, is vital to reduce the burden of chronic disease. This study aimed to investigate gender, age, screening practices, health beliefs, and perceived future health needs for healthy ageing. Methods Random probability sampling using self-completion surveys in 1456 adults residing in Australia. Results Screening behaviors were associated with gender and age. Men and women >51 years were more likely (27%) to have screening health checks than those <50 years (2%). Factors nominated to influence health were lifestyle (92%), relationships (82%), and environment (80%). Women were more likely to nominate preparedness to have an annual health check, willingness to seek advice from their medical practitioner and to attend education sessions. Numerous health fears were associated with ageing, however participants were more likely to have a financial (72%) rather than a health plan (42%). More women and participants >51 years wanted information regarding illness prevention than men or those aged <30 years. Conclusion Age and gender are associated with health related behaviors. Optimal health is perceived as a priority, yet often this perception is not translated into preventative action. These findings will inform future research and policy makers as we strive towards a healthier ageing society and the prevention of chronic disease. PMID:19563685

    Research on marriage in developing countries has been somewhat narrow in scope because of both conceptual and data limitations. While the feminist literature recognizes marriage as a key institutional site for the production and reproduction of gender hierarchies, little is known about the processes through which this relationship operates. This article uses data from the newly collected India Human Development Survey 2005 for 27,365 ever-married women aged 25–49 to explore ways in which different dimensions of gender in Indian society shape the decisions regarding age at marriage. We explore the impact of three dimensions of gender: (1) economic factors, such as availability of wage employment, dowry expectations, and wedding expenses; (2) indicators of familial empowerment, such as women’s role in household decision making and access to and control over resources; and (3) markers of gender performance, such as observance of purdah and male-female separation in the household. Results from hierarchical linear models confirm the importance of markers of gender performance but fail to demonstrate a large role for economic factors and familial empowerment. PMID:20879683

    Orientation in the environment can draw on a variety of cognitive strategies. We asked 634 healthy volunteers to perform a comprehensive battery administered through an internet website (www.gettinglost.ca), testing different orientation strategies in virtual environments to determine the effect of age and gender upon these skills. Older participants (46-67years of age) performed worse than younger participants (18-30 or 31-45years of age) in all orientation skills assessed, including landmark recognition, integration of body-centered information, forming association between landmarks and body turns, and the formation and use of a cognitive map. Among all tests, however, the ability to form cognitive maps resulted to be the significant factor best at predicting the individuals' age group. Gender effects were stable across age and dissociated for task, with males better than females for cognitive map formation and use as well as for path reversal, an orientation task that does not require the processing of visual landmarks during navigation. We conclude that age-related declines in navigation are common across all orientation strategies and confirm gender-specific effects in different spatial domains. PMID:21803342

    Normative data are limited on autonomic function tests, especially beyond age 60 years. We therefore evaluated these tests in a total of 557 normal subjects evenly distributed by age and gender from 10 to 83 years. Heart rate (HR) response to deep breathing fell with increasing age. Valsalva ratio varied with both age and gender. QSART (quantitative sudomotor axon-reflex test) volume was consistently greater in men (approximately double) and progressively declined with age for all three lower extremity sites but not the forearm site. Orthostatic blood pressure reduction was greater with increasing age. HR at rest was significantly higher in women, and the increment with head-up tilt fell with increasing age. For no tests did we find a regression to zero, and some tests seem to level off with increasing age, indicating that diagnosis of autonomic failure was possible to over 80 years of age.

    To identify age and gender differences among teen drivers in fatal crashes, we analyzed FARS data for 14,026crashes during 2007-2009. Compared with female teenagers, crashes of male teenagers were significantly more likely to involve BACs of 0.08% or more (21% vs. 12%), speeding (38% vs. 25%), reckless driving (17% vs. 14%), night driving (41% vs. 36%) and felony crashes (hit-and-run, homicide, or manslaughter) (8% vs. 6%) (all χ(2) p<0.001). Conversely, crashes of female teenagers were more likely to involve right angle ("t-bone") crashes (23% vs. 17%). Some crash characteristics associated with males and known to play a major role in crash causation also are more common in the youngest teenagers; for example, crashes of drivers age 15 or 16 were more likely than crashes of older teens to involve speeding or reckless driving. Crashes of drivers with BACs of 0.08% or higher increased with age in both genders. Some age effects differed by gender: for example, the proportion of crashes of female teens that involved speeding dropped from 38% to 22% between ages 15 and 19, while for males about 38% of crashes at each age involved speeding. The gender and age differences observed in teen drivers suggest opportunities for targeted driver training - for example, simulator training modules specifically tailored for male or female teenagers. Technology-based tools could also be developed to help parents to focus on the reckless driving tendencies of their sons. Insurance companies should consider ways to incentivize young males to drive more responsibly. PMID:23169121

    A biokinetic model for strontium in humans is necessary for quantification of internal doses due to strontium radioisotopes. The ICRP-recommended biokinetic model for strontium has limitation for use in a population study, because it is not gender specific and does not cover all age ranges. The extensive Techa River data set on 90Sr in humans (tens of thousands of measurements) is a unique source of data on long-term strontium retention for men and women of all ages at intake. These, as well as published data, were used for evaluation of age- and gender-specific parameters for a new compartment biokinetic model for strontium (Sr-AGe model). The Sr-AGe model has similar structure as the ICRP model for the alkaline earth elements. The following parameters were mainly reevaluated: gastro-intestinal absorption and parameters related to the processes of bone formation and resorption defining calcium and strontium transfers in skeletal compartments. The Sr-AGe model satisfactorily describes available data sets on strontium retention for different kinds of intake (dietary and intravenous) at different ages (0–80 years old) and demonstrates good agreement with data sets for different ethnic groups. The Sr-AGe model can be used for dose assessment in epidemiological studies of general population exposed to ingested strontium radioisotopes.

  10. Gender, ageing, and injustice: social and political contexts of bioethics.

    2005-05-01

    There has been considerable work in bioethics addressing injustice and gender oppression in the provision of healthcare services, in the interaction between client and healthcare professional, and in allocation of healthcare services within a particular hospital or health service. There remain several sites of continued injustice that can only be addressed adequately from a broader analytical perspective, one that attends to the social and political contexts framing healthcare policy and practice. Feminist bioethicists have a strong track record in providing this kind of analysis. Using current Australian aged care and welfare policy this paper demonstrates some of the ways in which issues of gender, age, and social inequity shape bioethical debate, policy, and practice in the areas of aged care and welfare provision. The author develops an argument that demonstrates the gender injustice underlying health care and welfare policy. This argument recognises the inevitability of human dependency relations, and questions the adequacy of current political theories to address the requirements for full and equal citizenship. The author shows that an adequate analysis of the ethics of aged healthcare depends on sufficient consideration of the social and political context within which healthcare policy is framed and an adequate understanding of human dependency.

    Based on approximately eight years of data collection with the nationwide Computer Registry of All Myopathies and Polyneuropathies (CRAMP) in the Netherlands, recent epidemiologic information for thirty neuromuscular disorders is presented. This overview includes age and gender data for a number of neuromuscular disorders that are either relatively frequently seen in the neuromuscular clinic, or have a particular phenotype. Since 2004, over 20,000 individuals with a neuromuscular disorder were registered in CRAMP; 56% men and 44% women. The number per diagnosis varied from nine persons with Emery-Dreifuss muscular dystrophy to 2057 persons with amyotrophic lateral sclerosis. Proportions of men ranged from 38% with post-polio syndrome to 68% with progressive spinal muscular atrophy, excluding X-chromosome linked disorders. Inclusion body myositis showed the highest median age at diagnosis of 70 years. These data may be helpful in the diagnostic process in clinical practice and trial readiness. PMID:27212207

    Effects of gender on grey matter (GM) volume differences in subcortical structures of the human brain have consistently been reported. Recent research evidence suggests that both gender and brain size influences volume distribution in subcortical areas independently. The goal of this study was to determine the effects of the interplay between brain size, gender and age contributing to volume differences of subcortical GM in the human brain. High-resolution T1-weighted images were acquired from 53 healthy males and 50 age-matched healthy females. Total GM volume was determined using voxel-based morphometry. We used model-based subcortical segmentation analysis to measure the volume of subcortical nuclei. Main effects of gender, brain volume and aging on subcortical structures were examined using multivariate analysis of variance. No significant difference was found in total brain volume between the two genders after correcting for total intracranial volume. Our analysis revealed significantly larger hippocampus volume for females. Additionally, GM volumes of the caudate nucleus, putamen and thalamus displayed a significant age-related decrease in males as compared to females. In contrast to this only the thalamic volume loss proved significant for females. Strikingly, GM volume decreases faster in males than in females emphasizing the interplay between aging and gender on subcortical structures. These findings might have important implications for the interpretation of the effects of unalterable factors (i.e. gender and age) in cross-sectional structural MRI studies. Furthermore, the volume distribution and changes of subcortical structures have been consistently related to several neuropsychiatric disorders (e.g. Parkinson's disease, attention deficit hyperactivity disorder, etc.). Understanding these changes might yield further insight in the course and prognosis of these disorders. PMID:26572143

    The abdominal aorta (AA) is predisposed to development of abdominal aneurysms (AAA), a focal dilatation with fatal consequences if left untreated. The blood flow patterns is thought to play an important role in the development of AAA. The purpose of this work is to investigate the blood flow patterns within a group of healthy volunteers (six females, eight males) aged 23 to 76 years to identify changes and differences related to age and gender. The healthy volunteers were categorized by gender (male/female) and age (below/above 35 years). Subject-specific flow and geometry data were acquired using the research interface on a Profocus ultrasound scanner (B-K Medical, Herlev, Denmark; segmentation of 3D magnetic resonance angiography (Magnetom Trio, Siemens Healthcare, Erlangen, Germany). The largest average diameter was among the elderly males (19.7 (+/- 1.33) mm) and smallest among the young females (12.4 (+/- 0.605) mm). The highest peak systolic velocity was in the young female group (1.02 (+/- 0.336) m/s) and lowest in the elderly male group (0.836 (+/- 0.127) m/s). A geometrical change with age was observed as the AA becomes more bended with age. This also affects the blood flow velocity patterns, which are markedly different from young to elderly. Thus, changes in blood flow patterns in the AA related to age and gender are observed. Further investigations are needed to determine the relation between changes in blood flow patterns and AAA development.

    Adults and children 5, 8, and 11 years of age listened to short excerpts of unfamiliar music that sounded happy, scary, peaceful, or sad. Listeners initially rated how much they liked each excerpt. They subsequently made a forced-choice judgment about the emotion that each excerpt conveyed. Identification accuracy was higher for young girls than for young boys, but both genders reached adult-like levels by age 11. High-arousal emotions (happiness and fear) were better identified than low-arousal emotions (peacefulness and sadness), and this advantage was exaggerated among younger children. Whereas children of all ages preferred excerpts depicting high-arousal emotions, adults favored excerpts depicting positive emotions (happiness and peacefulness). A preference for positive emotions over negative emotions was also evident among females of all ages. As identification accuracy improved, liking for positively valenced music increased among 5- and 8-year-olds but decreased among 11-year-olds. PMID:21530980

    Purpose In certain cancers, MDM2 SNP309 has been associated with early tumor onset in women. In melanoma, incidence rates are higher in women than in men among individuals less than age 40; however, among those older than age 50, melanoma is more frequent in men than in women. To investigate this difference, we examined the association between MDM2 SNP309, age at diagnosis, and gender among melanoma patients. Experimental Design Prospectively enrolled melanoma patients (N=227) were evaluated for MDM2 SNP309 and the related polymorphism, p53 Arg72Pro. DNA was isolated from patient blood samples and genotypes were analyzed by PCR-RFLP. Associations between MDM2 SNP309, p53 Arg72Pro, age at diagnosis, and clinicopathologic features of melanoma were analyzed. Results The median age at diagnosis was 13 years earlier among women with a SNP309 GG genotype (46 years) compared to women with TG+TT genotypes (59 years; p=0.19). Analyses using age dichotomized at each decade indicated that women with a GG genotype had significantly higher risks of being diagnosed with melanoma at ages less than 50 compared to women 50 and older, but not 60 and older. At ages less than 50, women with a GG genotype had a 3.89 times greater chance of being diagnosed compared to women with TG+TT genotypes (p=0.01). Similar observations were not seen among men. Conclusions Our data suggest that MDM2 may play an important role in the development of melanoma in women. The MDM2 SNP309 genotype may help identify women at risk for developing melanoma at a young age. PMID:19318491

    This study investigated the patterns of spirituality, gender, and age in cybergossip practices among Nigerian adolescents. The study utilized a descriptive survey method. Five hundred thirty adolescent students, randomly selected from four major cities in Nigeria, participated in the study. Their age range was 16 to 21. General Spirituality and Gossip Purpose scales were used to collect data from the participants. Data collected were subjected to t test statistics. Findings showed that there is no significant difference in the cybergossiping practices of adolescents based on their levels of spirituality. This reveals that spirituality is not an inhibiting factor in cybergossiping practices among the adolescents. However, there is significant difference between male and female youths in their cybergossiping practices. The results showed that females are more likely than males to be involved in cybergossiping activities. There is also significant difference between early and late adolescents' cybergossiping activities. The implication is that gossip and cybergossip is a natural tendency that involves communicative expression with a pleasure-seeking purpose. It is a habit that excludes no one despite spiritual, gender, or age factors. Therefore, this behavior should be positively directed away from abusive computing and communication. This work is unique because of the need for parents, guardians, and psychologists to design measures to identify and manage various moderating variables in children's computing practices for optimal positive outcomes.

    The authors examined concentrations of lead, cadmium, mercury, manganese, selenium, and chromium in feathers, liver, kidney, heart, and muscle of known-aged laughing gulls (Larus atricilla) that hatched in Barnegat Bay, New Jersey and were collected at John F. Kennedy International Airport, New York 1 to 7 years later. Concentrations differed significantly among tissues, and tissue entered all the regression models explaining the greatest variation in metal levels. Age of bird contributed significantly to the models for lead, cadmium, selenium, and chromium. Although there were significant gender differences in all body measurements except wing length, there were few differences in metal levels. Males had significantly higher lead levels in feathers, and females had significantly higher selenium levels in heart and muscle tissue. For lead, 3-year olds had the highest levels in the heart, liver, and kidney, and levels were lower thereafter. Mercury levels in feathers and heart decreased significantly with age. Cadmium levels increased significantly with age for feathers, heart, liver, and muscle, although there was a slight decrease in the 7-year olds. Selenium levels decreased significantly with age for all tissues. Chromium levels increased with age for liver and heart.

    Long-term marriages (N = 156) varying in spouses' age (40-50 years or 60-70 years) and relative marital satisfaction (satisfied and dissatisfied) were studied. Spouses independently completed demographic, marital, and health questionnaires and then participated in a laboratory-based procedure focused on areas of conflict and sources of pleasure. Findings supported a positive view of older marriages. Compared with middle-aged marriages, older couples evidenced (a) reduced potential for conflict and greater potential for pleasure in several areas (including children), (b) equivalent levels of overall mental and physical health, and (c) lesser gender differences in sources of pleasure. The relation between marital satisfaction and health was stronger for women than for men. In satisfied marriages, wives' and husbands' health was equivalent; in dissatisfied marriages, wives reported more mental and physical health problems than did their husbands. PMID:8323733

    Metabolites of cerebrospinal biogenic amines (dopamine and serotonin)are an important tool in clinical research and diagnosis of children with neurotransmitter disorders. In this article we focused on finding relationships between the concentration of biogenic amine metabolites, age, and gender. We analyzed 148 samples from children with drug resistant seizures of unknown etiology and children with mild stable encephalopathy aged 0-18 years. A normal profile of biogenic amineswas found in 107 children and those children were enrolled to the study group. The CSF samples were analyzed by HPLC with an electrochemical detector. The concentrations of the dopamine and serotonin metabolites homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA), respectively, were high at birth, gradually decreasing afterward until the 18 years of age. Nevertheless, the HVA/5-HIAA ratio did not vary with age, except in the children below 1 year of age. In the youngest group we observed a strong relationship between the HVA/5-HIAA ratio and age (r = 0.69, p < 0.001). There were no statistical differences in the level of both dopamine and serotonin metabolites between boys and girls, although a tread toward lower HVA and 5-HIAA in the boys was noticeable. Significant inter-gender differences in the level of HVA and 5-HIAA were noted only in the age-group of 1-4 years, with 5-HIAA being higher in the girls than boys (p = 0.004). In conclusion, the study revealed that the concentration of biogenic amine metabolites is age and sex dependent. PMID:26453071

    The association between breed, gender and age and cardiovascular disorders in the insured dog population in Japan was investigated, using multiple logistic regression analysis and data from 299,555 dogs insured between April 2010 and March 2011. The overall annual prevalence of cardiovascular disorder diagnosis was 2.1%. Using the Miniature Dachshund as the reference breed, Cavalier King Charles Spaniel had the highest odds of cardiovascular disorder with a ratio of 16.2 (95% confidence interval: 14.4–18.2), followed by Maltese, Pomeranian, Chihuahua and Shih Tzu. Male dogs had increased odds of 1.2 (1.1–1.3). The dogs had increased odds of having cardiovascular disorder by 1.5 times as their age increased by one year. PMID:26460315

    Purpose This cross-sectional report includes ocular component data as a function of age, gender, and ethnicity from the Collaborative Longitudinal Evaluation of Ethnicity and Refractive Error (CLEERE) Study. Methods The ocular components of 4881 school-aged children were examined using cycloplegic autorefraction (refractive error), keratometry (corneal curvature), ultrasonography (axial dimensions), and videophakometry (lens curvature). Results The average age (± SD) was 8.8 ± 2.3 years, and 2458 were girls (50.4%). Sixteen percent were African American, 14.8% were Asian, 22.9% were Hispanic, 11.6% were Native American, and 34.9% were White. More myopic/less hyperopic refractive error was associated with greater age, especially in Asians, less in Whites and African Americans. Corneal power varied slightly with age, with girls showing a greater mean corneal power. Native-American children had greater corneal toricity with a markedly flatter horizontal corneal power. Anterior chambers were deeper with age, and boys had deeper anterior chambers. Native-American children had the shallowest anterior chambers and Whites the deepest. Girls had higher Gullstrand and calculated lens powers than boys. Boys had longer vitreous chambers and axial lengths, and both were deeper with age. Native Americans had the longest vitreous chambers and Whites the shortest. Conclusions Most ocular components showed little clinically meaningful variation by ethnicity. The shallower anterior chambers and deeper vitreous chambers of Native-American children appeared to be offset by flatter corneas. The relatively deeper anterior chamber and shallower vitreous chambers of White children appeared to be offset by steeper corneas. Asian children had more myopic spherical equivalent refractive errors, but for a given refractive error the ocular parameters of Asian children were moderate in value compared to those of other ethnic groups. Asian children may develop longer, myopic eyes more often

    This study aimed to analyze temporal trends by gender and age in Clostridium difficile infection (CDI)-related hospitalization rates in the Autonomous Community of Madrid (Spain) over a 12-year period. A population-based cross-sectional study of all hospital admissions with a CDI diagnosis from 2003 to 2014 was carried out. Annual age-specific hospitalization rates were calculated by gender. All the analyses were performed separately for total hospitalizations and hospitalizations with CDI as the primary diagnosis. Joinpoint regression models were used to analyze time trends. A total of 13,526 hospital discharges were identified (26.8 % with CDI as the primary diagnosis). In both sexes, a gradient in age-specific rates was observed, ranging in 2014 from 5.92 hospitalizations per 100,000 person-years in patients <15 years of age to 378.96 in patients ≥85 years of age. Since 2009, in the age group of 15-44 years, both men and women presented an increasing trend of around 18 %. A significantly increasing trend was detected in women of age 45-84 years, with an estimated annual percentage of change of 7.6 % in the age group of 45-64 years, and rounding with 4.5 % in the age group of 65-84 years. In men of age 45-64 years, the average annual percentage of increase was 4.7 %, and it was 21.1 % between 2010 and 2014 in the age group of 65-74 years. No trends were identified in the 85 years and over age group. Surveillance methods to assess trends by age group should be implemented. Preventive and therapeutic initiatives should remain a priority. PMID:27056555

  6. Gender, ageing & carework in East and Southern Africa: A review

    An estimated 58 million persons aged 60-plus live in sub-Saharan Africa; by 2050 that number will rise sharply to 215 million. Older Africans traditionally get care in their old age from the middle generation. But in East and Southern Africa, HIV has hollowed out that generation, leaving many older persons to provide care for their children’s children without someone to care for him or herself in old age. Simultaneously, the burden of disease among older persons is changing in this region. The result is a growing care deficit. This article examines the existing literature on care for and by older persons in this region, highlighting understudied aspects of older persons’ experiences of ageing and care – including the positive impacts of carework, variation in the region, and the role of resilience and pensions. We advance a conceptual framework of gendered identities – for both men and women – and intergenerational social exchange to help focus and understand the complex interdependent relationships around carework, which are paramount in addressing the needs of older persons in the current care deficit in this region, and the Global South more generally.

    Cardiac pathologies are the major aspect in the treatment strategies for Marfan syndrome (MFS). In this progressive disease, less is known about manifestations and progression of cardiovascular symptoms in children. To define a certain decision regarding therapeutic options, knowledge concerning the onset of cardiovascular findings is essential. From 1998 to 2011, suspected pediatric Marfan patients were subjected to a standardized diagnostic program. Cardiovascular findings were analyzed in terms of age at first clinical manifestation, prevalence and gender differences, morbidity, mortality, and treatment. Marfan syndrome was diagnosed in 82 patients (46 boys; mean age at diagnosis, 9.0 ± 5.7 years). At first presentation, aortic root dilation was found in 56 % of patients, mitral valve prolapse in 31 %, whereas pulmonary artery dilation was detected in 22 % and tricuspid valve prolapse in only 17 % of patients. Aortic (2.5 %) and mitral valve regurgitations (22 %) are significantly correlated with aortic root dilation (p < 0.01) and mitral valve prolapse (p < 0.05) but without relevant progression during childhood. Prophylactic medication was initiated for 42 % of the patients (mean age, 8.0 ± 4.5 years) because of progressive aortic root dilation. Aortic dissection did not appear. Aortic root surgery was needed for 4 % of the patients. Gender-specific differences in cardiovascular findings, progression of disease, or treatment did not appear. Comparable with adults, aortic root dilation is the most frequent cardiovascular finding in children and associated with relevant morbidity, whereas aortic and mitral valve regurgitation are of minor clinical relevance. Manifestation at an early age and slow progression of cardiovascular findings underscore the necessity of repeated echocardiographic examinations for early diagnosis and start of prophylactic treatment.

    Stroke is the second leading cause of death and the most important cause of adult disability worldwide and in Croatia. In the past, stroke was almost exclusively considered to be a disease of the elderly; however, today the age limit has considerably lowered towards younger age. The aim of this study was to determine age and gender impact on stroke patients in a Croatian urban area during one-year survey. The study included all acute stroke patients admitted to our Department in 2004. A compiled stroke questionnaire was fulfilled during hospitalization by medical personnel on the following items: stroke risk factors including lifestyle habits (smoking and alcohol), pre-stroke physical ability evaluation, stroke evolution data, laboratory and computed tomography findings, outcome data and post-stroke disability assessment. Appropriate statistical analysis of numerical and categorical data was performed at the level of p < 0.05. Analysis was performed on 396 patients, 24 of them from the younger adult stroke group. Older stroke patients had worse disability at hospital discharge and women had worse disabilities at both stroke onset and hospital discharge, probably due to older age at stroke onset. Younger patients recovered better, while older patients had to seek secondary medical facilities more often, as expected. The most important in-hospital laboratory findings in young stroke patients were elevated lipid levels, while older patients had elevated serum glucose and C-reactive protein. Stroke onset in younger patients most often presented with sudden onset headache; additionally, onset seizure was observed more frequently than expected. Stroke risk factor analysis showed that women were more prone to hypertension, chronic heart failure and atrial fibrillation, whereas men had carotid disease more frequently, were more often smokers and had higher alcohol intake. Additionally, age analysis showed that heart conditions and smoking were more prevalent among older

    2003-04-01

    Eminent composers in Western European art music continue to be predominantly male and eminence in contemporary pop music is similarly male dominated. One contributing factor may be the continuing under-valuation of women's music. Possible anti-female bias in a contemporary genre was investigated using the Goldberg paradigm to elicit judgments of New Age compositions. Since stronger stereotyping effects occur when information provided about individuals is sparse, fictitious male and female composers were presented either by name only or by name with a brief biography. Evidence for anti-female bias was found in the name-only condition and was stronger when liking for the music was controlled. Other findings were the tendency for females to give higher ratings, and the association of gender differences in liking of the music with ratings of quality in the name-only condition. These results are relevant to the design of formal assessment procedures for musical composition. PMID:12778980

    A questionnaire with 78 questions concerning the situation of ankylosing spondylitis (AS) sufferers in Germany was distributed to a representative 3000 out of the more than 14,000 patient members of the German AS society; 1614 patients (54%) responded. The age distribution of these patients roughly agrees with that expected due to the distribution of the age at diagnosis and the age distribution of the German population. The group of patients more than 65 years old is, however, under-represented. It turned out that at least 28% of the patients responding do not suffer from idiopathic AS but from other spondyloarthritides (spondylitic psoriasis, spondyloarthritis combined with Crohn's disease or ulcerative colitis). The distribution of the age at disease onset agrees well with that published in 1984 by van der Linden et al.: For 4% of the patients, the age at appearance of the first spondylitic symptoms was less than 15 years, for 90% it was 15-40 years and for the remaining 6% more than 40 years. The average age at disease onset was 25.6 years. The spondyloarthritides do not differ significantly in the distribution of the age at the first spondylitic symptoms. The distribution of the age at diagnosis did not differ significantly between male and female patients, in contrast to the findings by van der Linden et al. in 1984. The average age at diagnosis was 34.3 and 35.3 years for male and female patients, respectively. The resulting mean diagnosis delay for male and female patients was 8.4 and 9.8 years, respectively. Whereas the average diagnosis delay was still 15 years for patients with disease onset in the 1950s, it was only 71/2 years for patients with disease onset in 1975-79. It is not yet possible to predict if an average diagnosis delay less than 71/2 years results for patients with a disease onset later than 1980, because the number of further diagnoses to be expected for patients with disease onset in these years is not negligible.

    Intelligent digital signage systems transmit customized advertising and information by analyzing users and customers, unlike existing system that presented advertising in the form of broadcast without regard to type of customers. Currently, development of intelligent digital signage system has been pushed forward vigorously. In this study, we designed a system capable of analyzing gender and age of customers based on image obtained from camera, although there are many different methods for analyzing customers. We conducted age and gender recognition experiments using public database. The age/gender recognition experiments were performed through histogram matching method by extracting Local binary patterns (LBP) features after facial area on input image was normalized. The results of experiment showed that gender recognition rate was as high as approximately 97% on average. Age recognition was conducted based on categorization into 5 age classes. Age recognition rates for women and men were about 67% and 68%, respectively when that conducted separately for different gender.

    Abstract We evaluated whether age- and gender-based colorectal cancer screening is cost-effective. Recent studies in the United States identified age and gender as 2 important variables predicting advanced proximal neoplasia, and that women aged <60 to 70 years were more suited for sigmoidoscopy screening due to their low risk of proximal neoplasia. Yet, quantitative assessment of the incremental benefits, risks, and cost remains to be performed. Primary care screening practice (2008–2015). A Markov modeling was constructed using data from a screening cohort. The following strategies were compared according to the Incremental Cost Effectiveness Ratio (ICER) for 1 life-year saved: flexible sigmoidoscopy (FS) 5 yearly; colonoscopy 10 yearly; FS for each woman at 50- and 55-year old followed by colonoscopy at 60- and 70-year old; FS for each woman at 50-, 55-, 60-, and 65-year old followed by colonoscopy at 70-year old; FS for each woman at 50-, 55-, 60-, 65-, and 70-year old. All male subjects received colonoscopy at 50-, 60-, and 70-year old under strategies 3 to 5. From a hypothetical population of 100,000 asymptomatic subjects, strategy 2 could save the largest number of life-years (4226 vs 2268 to 3841 by other strategies). When compared with no screening, strategy 5 had the lowest ICER (US$42,515), followed by strategy 3 (US$43,517), strategy 2 (US$43,739), strategy 4 (US$47,710), and strategy 1 (US$56,510). Strategy 2 leads to the highest number of bleeding and perforations, and required a prohibitive number of colonoscopy procedures. Strategy 5 remains the most cost-effective when assessed with a wide range of deterministic sensitivity analyses around the base case. From the cost effectiveness analysis, FS for women and colonoscopy for men represent an economically favorable screening strategy. These findings could inform physicians and policy-makers in triaging eligible subjects for risk-based screening, especially in countries with limited colonoscopic

    Uveitis is a vision threatening inflammation of the eye that carries considerable morbidity. It is responsible for 10% of legal blindness in the United States and up to 25% in the developing world. Uveitis in patients more than 60 years of age is less common. The aging body has a changing response of the immune system, which might reflect a different pattern of uveitis in the elderly population. In this paper we review the incidence and patterns of uveitis in the elderly as reported in the literature and discuss changes with time. We also delineate a thorough differential diagnosis of de novo uveitis in the elderly. PMID:26090218

    Most research to date on implicit gender stereotyping has been conducted with one age group – young adults. The mechanisms that underlie the on-line processing of stereotypical information in other age groups have received very little attention. This is the first study to investigate real time processing of gender stereotypes at different age levels. We investigated the activation of gender stereotypes in Italian in four groups of participants: third- and fifth-graders, young and older adults. Participants heard a noun that was stereotypically associated with masculine (preside “headmaster”) or feminine roles (badante “social care worker”), followed by a male (padre “father”) or female kinship term (madre “mother”). The task was to decide if the two words – the role noun and the kinship term – could describe the same person. Across all age groups, participants were significantly faster to respond, and significantly more likely to press ‘yes,’ when the gender of the target was congruent with the stereotypical gender use of the preceding prime. These findings suggest that information about the stereotypical gender associated with a role noun is incorporated into the mental representation of this word and is activated as soon as the word is heard. In addition, our results show differences between male and female participants of the various age groups, and between male- and female-oriented stereotypes, pointing to important gender asymmetries.

    In the present study, we perform an association analysis focusing on the expression changes of 1344 RNA Binding proteins (RBPs) as a function of age and gender in human liver. We identify 88 and 45 RBPs to be significantly associated with age and gender respectively. Experimental verification of several of the predicted associations in mice confirmed our findings. Our results suggest that a small fraction of the gender-associated RBPs (~40%) are expressed higher in males than females. Altogether, these observations show that several of these RBPs are important and conserved regulators in maintaining liver function. Further analysis of the protein interaction network of RBPs associated with age and gender based on the centrality measures like degree, betweenness and closeness revealed that several of these RBPs might be prominent players in aging liver and impart gender specific alterations in gene expression via the formation of protein complexes. Indeed, both age and gender-associated RBPs in liver were found to show significantly higher clustering coefficients and network centrality measures compared to non-associated RBPs. The compendium of RBPs and this study will help us gain insight into the role of post-transcriptional regulatory molecules in aging and gender specific expression of genes. PMID:25824884

  8. ASD in females: are we overstating the gender difference in diagnosis?

    PubMed

    Kreiser, Nicole L; White, Susan W

    2014-03-01

    Autism spectrum disorder (ASD) is predominantly diagnosed in males. In explaining the differential rate of occurrence in males and females, biogenetic models have been proposed and studied, often to the exclusion of potential social or cultural factors that may influence different rates of diagnosis across the genders. In this theoretical paper, we consider sociocultural influences that may contribute to the differential expression of ASD in females and partially explain potential underidentification of ASD in females. Based on our synthesis of the extant literature, we propose that ASD may be underidentified in affected females without co-occurring intellectual impairment, owing to a pattern of subtle yet potentially meaningful gender differences in symptom manifestation (e.g., less unusual stereotyped and repetitive behaviors in females, increased prevalence of internalizing problems in females) and gender inequities in research on the ASD phenotype that potentially contributes to biases in assessment tools and diagnostic practices. We offer recommendations for future research directions on gender differences in ASD, and we suggest implications to inform best practice and policy for the assessment of females with ASD.

    Age-related macular degeneration (AMD) is the most common cause of irreversible visual impairment in older populations in industrialized nations. AMD is a late-onset deterioration of photoreceptors and retinal pigment epithelium in the central retina caused by various environmental and genetic factors. Great strides in our understanding of AMD pathogenesis have been made in the past several decades, which have translated into revolutionary therapeutic agents in recent years. In this review, we describe the clinical and pathologic features of AMD and present an overview of current diagnosis and treatment strategies. PMID:26239130

    Age and gender of an individual, when available, can contribute to identification decisions provided by primary biometrics and help improve matching performance. In this paper, we propose a system which automatically infers age and gender from the fingerprint image. Current approaches for predicting age and gender generally exploit features such as ridge count, and white lines count that are manually extracted. Existing automated approaches have significant limitations in accuracy especially when dealing with data pertaining to elderly females. The model proposed in this paper exploits image quality features synthesized from 40 different frequency bands, and image texture properties captured using the Local Binary Pattern (LBP) and the Local Phase Quantization (LPQ) operators. We evaluate the performance of the proposed approach using fingerprint images collected from 500 users with an optical sensor. The approach achieves prediction accuracy of 89.1% for age and 88.7% for gender.

    Purpose of the Study: The purpose was to investigate the differences in tooth shade value according to age, gender and skin color among a sample of the local population in Bengaluru, India. Methodology: The study comprised 100 subjects belonging to both gender between the age groups of 16 years to 55 years. Tooth shade values of permanent maxillary left or right central incisors were recorded using the Vitapan 3D-Master shade guide. Skin color was matched using the Radiance compact makeup shades as a guide. Results: Chi-square statistical test demonstrated that younger subjects have lighter tooth shade values. No statistically significant differences were recorded in tooth shade value according to gender or skin color. Conclusion: Within the limitations of the current study, it can be concluded that tooth shade value is significantly influenced by age. Gender and skin color appear not to have a significant relation to tooth shade value. PMID:26929500

    Research and theorizing on gender and age differences in self-esteem have played a prominent role in psychology over the past 20 years. However, virtually all empirical research has been undertaken in the United States or other Western industrialized countries, providing a narrow empirical base from which to draw conclusions and develop theory. To broaden the empirical base, the present research uses a large Internet sample (N = 985,937) to provide the first large-scale systematic cross-cultural examination of gender and age differences in self-esteem. Across 48 nations, and consistent with previous research, we found age-related increases in self-esteem from late adolescence to middle adulthood and significant gender gaps, with males consistently reporting higher self-esteem than females. Despite these broad cross-cultural similarities, the cultures differed significantly in the magnitude of gender, age, and Gender × Age effects on self-esteem. These differences were associated with cultural differences in socioeconomic, sociodemographic, gender-equality, and cultural value indicators. Discussion focuses on the theoretical implications of cross-cultural research on self-esteem. (PsycINFO Database Record PMID:26692356

    Cytokines play important roles as regulators of cell functions, and over the last decades a number of cytokine assays have been developed. The aim of the present study was to investigate the effects of age and gender on a large number of cytokines. Plasma samples were collected from 33 healthy blood donors. The samples were analyzed using a multiplex proximity extension assay (PEA) allowing simultaneous measurement of 92 cytokines and four technical controls. Biomarkers with less than 80% quantitative results were excluded leaving 63 cytokines that were analyzed for the effects of gender and age. The plasma level of three of the investigated biomarkers (DNER, MCP-4 and MMP-10) were found to be significantly different for the two genders (adjusted p-value<0.05), and 15 of the biomarkers (CCL11, CCL25, CDCP1, CSF-1, CXCL11, CXCL9, FGF-23, Flt3L, HGF, IL-10RB, MCP-3, MCP-4, MMP-10, OPG, VEGF-A) were significantly associated with age. This study reveals the effects of age and gender on a large number of cytokine assays. CXCL5 and TNFB were significantly higher in females, while the other markers with significant gender-dependent differences were higher in males. For the markers that were significantly associated with age, only CXCL6 was found to decrease with age, while the other biomarkers increased with age. PMID:26080062

    Purpose Diagnosis of Rett syndrome (RTT) is often delayed. We sought to determine type of physician who typically makes the diagnosis of RTT and to identify risk factors for delayed diagnosis. Methods One-thousand eighty-five participants from the multicenter longitudinal RTT natural history study with classic and atypical RTT were recruited from 2006 to 2014. Age of diagnosis, diagnostician, diagnostic criteria, clinical and developmental data were collected. Results Among 919 classic and 166 atypical RTT participants, median diagnosis age was 2.7 years (interquartile range 2.0–4.1) in classic and 3.8 years (interquartile range 2.3–6.9) in atypical RTT. Pediatricians made the diagnosis of classic RTT rarely (5.2%); however, proportion diagnosed by pediatricians increased since 2006. Since the first diagnostic criteria, the age of diagnosis decreased among subspecialists but not pediatricians. Odds of a pediatrician making the diagnosis of classic RTT were higher if a child stopped responding to parental interaction, and lower if they possessed gastro-esophageal reflux, specific stereotypies, lost babbling or the ability to follow commands. Delayed acquisition of basic gross motor skills or finger feeding were associated with younger diagnosis; delayed acquisition of higher level fine motor skills, later onset of supportive features, and normal head circumference were associated with late diagnosis. 33% with microcephaly before 2.5 years were diagnosed after the median age of 2.7 years. Conclusions Age of RTT diagnosis has improved among subspecialists, and pediatricians have made the diagnosis of classic RTT more frequently since 2006. Strategies for educating diagnosticians should incorporate specific risk factors for delayed diagnosis. PMID:25801175

  5. Association of suicide rates for elderly age bands with gender equality.

    A lower sex ratio (male to female) of elderly suicide rates in several Asian countries have been attributed to gender inequality on several parameters. The association of two proxy measures of gender equality (value of the gender empowerment measure and the gender-related development index) and the male to female sex ratio of suicide rates in the age bands 65-74 yr. and 75+ yr. was examined using multiple linear regression. The two proxy measures of gender equality did not account for significant variance in the male to female sex ratio of suicide rates in the age bands 65-74 yr. and 75+ yr. Association of gender equality with the male to female sex ratio of suicide rates requires further clarification in both cross-sectional studies across different countries and longitudinal studies within individual countries for all age bands. Such studies should, in addition to the GEM and the GDI, include other measures of gender equality including sex differences in educational attainment, income, poverty, housing, employment, access to healthcare and social welfare services, and urbanisation.

    Background Poor glycemic control early in the course of type 1 diabetes mellitus (T1DM) increases the risk for microvascular complications. However, predictors of deteriorating control after diagnosis have not been described, making it difficult to identify high-risk patients and proactively provide aggressive interventions. Objective We examined whether diagnostic age, gender, and race were associated with deteriorating glycemic control during the first 5 years after diagnosis. Participants 2218 pediatric patients with T1DM. Methods We conducted a longitudinal cohort study of pediatric patients with T1DM from the Midwest USA, 1993–2009, evaluating within-patient glycated hemoglobin (HbA1c) trajectories constructed from all available HbA1c values within 5 years of diagnosis. Results 52.6% of patients were male; 86.1% were non-Hispanic Caucasian. The mean diagnostic age was 9.0±4.1 years. The mean number of HbA1c values/year/participant was 2.4±0.9. HbA1c trajectories differed markedly across age groups, with older patients experiencing greater deterioration than their younger counterparts (p<0.001). HbA1c trajectories, stratified by age, varied markedly by race (p for race×diagnostic age <0.001). Non-Hispanic African-American patients experienced higher initial HbA1c (8.7% vs 7.6% (71.6 vs 59.6 mmol/mol); p<0.001), and greater deterioration in HbA1c than non-Hispanic Caucasian patients across diagnostic ages (rise of 2.04% vs 0.99% per year (22.3 vs 10.8 mmol/mol/year); p<0.0001). Conclusions Older diagnostic age and black race are major risk factors for deterioration in glycemic control early in the course of T1DM. These findings can inform efforts to explore the reasons behind these differences and develop preventive interventions for high-risk patients. PMID:25452876

    Objectives. We examined sexual orientation differences in adolescent smoking and intersections with race/ethnicity, gender, and age. Methods. We pooled Youth Risk Behavior Survey data collected in 2005 and 2007 from 14 jurisdictions; the analytic sample comprised observations from 13 of those jurisdictions (n = 64 397). We compared smoking behaviors of sexual minorities and heterosexuals on 2 dimensions of sexual orientation: identity (heterosexual, gay–lesbian, bisexual, unsure) and gender of lifetime sexual partners (only opposite sex, only same sex, or both sexes). Multivariable regressions examined whether race/ethnicity, gender, and age modified sexual orientation differences in smoking. Results. Sexual minorities smoked more than heterosexuals. Disparities varied by sexual orientation dimension: they were larger when we compared adolescents by identity rather than gender of sexual partners. In some instances race/ethnicity, gender, and age modified smoking disparities: Black lesbians–gays, Asian American and Pacific Islander lesbians–gays and bisexuals, younger bisexuals, and bisexual girls had greater risk. Conclusions. Sexual orientation, race/ethnicity, gender, and age should be considered in research and practice to better understand and reduce disparities in adolescent smoking. PMID:24825218

    Aim: To evaluate the ability of five clinimetric instruments to discriminate between subjects >60 years of age living at home versus those living in a residency. Methods: Trained nutritionists applied five instruments (cognition/depression/functionality/nutrition/appetite) to 285 subjects with majorities of women (64%), aged <80 years (61%), and home residents (54%). Results: Multivariable regression models were generated for each instrument using age, gender, and residency as independent variables. Age was associated with worsening scores in the five instruments whereas residency showed association in three instruments, and gender in two. Score-age regressions by place of residency showed differences suggesting that Mundet residents had increasingly worse scores with increasing age than home dwellers for cognition, depression, and nutrition. Also, living at home prevented the worsening of depression with increasing age. In contrast, functionality and appetite deteriorated at a similar rate for home and Mundet residents suggesting an inability of these two instruments to discriminate between settings. Score-age regressions by gender suggested that males have less cognitive problems at 60 and 80 years of age but not at 100 years, and better appetite than women at all ages. Conclusion: Increasing age proved to be associated to worsening scores in the five instruments but only three were able to detect differences according to setting. An interesting observation was that living at home appeared to prevent the depression increase with increasing age seen in Mundet residents. PMID:25593910

    Ultra-endurance challenges were once the stuff of legend isolated to the daring few who were driven to take on some of the greatest physical endurance challenges on the planet. With a growing fascination for major physical challenges during the nineteenth century, the end of the Victorian era witnessed probably the greatest ultra-endurance race of all time; Scott and Amundsen's ill-fated race to the South Pole. Ultra-endurance races continued through the twentieth century; however, these events were isolated to the elite few. In the twenty-first century, mass participation ultra-endurance races have grown in popularity. Endurance races once believed to be at the limit of human durability, i.e. marathon running, are now viewed as middle-distance races with the accolade of true endurance going to those willing to travel significantly further in a single effort or over multiple days. The recent series of papers in Extreme Physiology & Medicine highlights the burgeoning research data from mass participation ultra-endurance events. In support of a true 'mass participation' ethos Knetchtle et al. reported age-related changes in Triple and Deca Iron-ultra-triathlon with an upper age of 69 years! Unlike their shorter siblings, the ultra-endurance races appear to present larger gender differences in the region of 20% to 30% across distance and modality. It would appear that these gender differences remain for multi-day events including the 'Marathon des Sables'; however, this gap may be narrower in some events, particularly those that require less load bearing (i.e. swimming and cycling), as evidenced from the 'Ultraman Hawaii' and 'Swiss Cycling Marathon', and shorter (a term I used advisedly!) distances including the Ironman Triathlon where differences are similar to those of sprint and endurance distances i.e. c. 10%. The theme running through this series of papers is a continual rise in participation to the point where major events now require selection races to remain

    We examined the association of gender, ethnicity, age, and education with 60 Rorschach scores using three clinical and nonclinical samples of adults and youths (ns = 640, 249, and 241). As anticipated for our data sets, there were no reliable associations for gender, ethnicity, or adult age. However, in adults years of education was associated with variables indicative of complexity, the articulation of subtlety and nuance, cognitive synthesis, and coping resources. In the clinical sample of youths, increasing age was primarily associated with more conventional perception and less illogical thought processes. Limitations are discussed in conjunction with further research that could address them, along with implications for applied practice. PMID:25059682

    Background/objectives One phenomenon of skin aging is loss of cutaneous elasticity. Measurement of cutaneous resonance running time (CRRT) is a method to assess skin elasticity. Yet, information regarding directional changes of CRRT associated with age, body sites and gender is not yet available. In the present study, we assessed whether changes in CRRT vary with age, body sites and gender in a normal Chinese population. Methods A Reviscometer was used to measure CRRTs in various directions on the left dorsal hand, the forehead and the left canthus of 806 normal Chinese volunteers, aged 2.5-94 years. Results With aging, CRRTs decreased in all directions on the hand, the forehead, and the canthus. A more dramatic reduction of CRRTs on the forehead and the canthus were observed at both the 2–8 and 3–9 o’clock directions. CRRTs in males aged 11– 20 years old were longer than those in females at some directions on all three body sites. Females between 21 and 40 years old showed longer CRRTs than males in some directions of the hand. There were no gender differences in subjects aged 0–10 (except on the canthus) and over 81 years old. Conclusion CRRTs vary with age, body sites and gender. PMID:21039906

    2015-01-01

    In the recent years, short-term heart rate variability (HRV) describing complex variations of beat-to-beat interval series that are mainly controlled by the autonomic nervous system (ANS) has been increasingly analyzed to assess the ANS activity in different diseases and under various conditions. In contrast to long-term HRV analysis, short-term investigations (<30 min) provide a test result almost immediately. Thus, short-term HRV analysis is suitable for ambulatory care, patient monitoring and all those applications where the result is urgently needed. In a previous study, we could show significant variations of 5-min HRV indices according to age in almost all domains (linear and nonlinear) in 1906 healthy subjects from the KORA S4 cohort. Based on the same group of subjects, general gender-related influences on HRV indices are to be determined in this study. Short-term 5-min HRV indices from linear time and frequency domain and from nonlinear methods (compression entropy, detrended fluctuation analysis, traditional and segmented Poincaré plot analysis, irreversibility analysis, symbolic dynamics, correlation and mutual information analysis) were determined from 782 females and 1124 males. First, we examined the gender differences in two age clusters (25–49 years and 50–74 years). Secondly, we investigated the gender-specific development of HRV indices in five age decade categories, namely for ages 25–34, 35–44, 45–54, 55–64 and 65–74 years. In this study, significant modifications of the indices according to gender could be obtained, especially in the frequency domain and correlation analyses. Furthermore, there were significant modifications according to age in nearly all of the domains. The gender differences disappeared within the last two age decades and the age dependencies disappeared in the last decade. To summarize gender and age influences need to be considered when performing HRV studies even if these influences only partly differ. PMID

    OBJECTIVE. Body image and perceived attractiveness were examined, and the impact of age, gender, and body mass index (BMI) was analyzed and discussed from an evolutionary and a sociocultural perspective. METHOD. The population-based sample consisted of 11,468 Finnish men and women aged 18 to 49 years. RESULTS. Both age-related decrease and increase in body satisfaction was detected as well as interactions between age and gender. Some effects were nonlinear. Women were generally less satisfied with their bodies than men. BMI had a stronger influence on women's body image than men's. DISCUSSION. It was proposed that it is insufficient to merely study how age affects general body image because adults might become more satisfied with some aspects of their bodies as a function of age and less satisfied with other aspects. Body satisfaction might also fluctuate during different phases of the adult life, and the patterns possibly differ between men and women. PMID:19897779

    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.

    Introduction: Studies have indicated that elderly anthropometric dimensions will different for each person. To determine whether there are differences in the anthropometric data of Javanese elderly, this study will analyze whether the variables of age, gender, origin, and body mass index (BMI) have been associated with elderly anthropometric dimensions. Age will be divided into elderly and old categories, gender will divide into male and female, origins were divided into Yogyakarta and Central Java, and for BMI only use the normal category. Method: Anthropometric studies were carried out on 45 elderly subjects in Sleman,Yogyakarta. Results and Discussion: The results showed that some elderly anthropometric dimensions were influenced by age, origin, and body mass index but gender doesn't significantly affect the elderly anthropometric dimensions that exist in the area of Sleman. The analysis has provided important aid when designing products that intended to the Javanese elderly Population.

    Over the past century, the population of Korea has aged rapidly as a result of decreasing fertility and mortality. Furthermore, the percentage of the population aged 65 and older is expected to double from 7% to 14% within 18 years, a much shorter doubling period than in most other developed countries. As Korean society ages, interest in healthy and successful ageing has increased. However, although previous studies have examined various determinants of successful ageing, such as socioeconomic status, gender differences have been neglected. This study investigated gender differences as factors in successful ageing among elderly men and women. Successful ageing has been defined as having high levels of physical and social functioning. Physical functioning includes having no difficulties with activities of daily living (ADL) or instrumental activities of daily living (IADL). Social functioning is defined as participation in at least one of the following social activities: paid work, religious gatherings or volunteer service. Data for this study were obtained from a representative sample of 761 community-living individuals aged 65-84 years (340 males, 421 females); the respondents were interviewed face-to-face as part of the third wave of the Hallym Ageing Study (2007). Socioeconomic status appears to have a greater gender-specific effect on physical functioning than on social functioning. Especially for elderly men, a higher monthly individual income was significantly related to a higher level of physical functioning. Among elderly women, a higher level of education was associated with a higher level of physical functioning. In a major metropolis, elderly men had low social functioning and elderly women had low physical functioning. As Korea's population ages, successful ageing has received much attention. This study shows that policies promoting successful ageing must consider gender differences and associated socioeconomic factors. PMID:19703332

    Aim and Objective: To investigate age, sex based on gonial angle, width and breadth of the ramus of the mandible by digital orthopantomograph. Materials and Methods: A total of 200 panoramic radiographic images were selected. The age of the individuals ranged between 4 and 75 years of both the gender - males (113) and females (87) and selected radiographic images were measured using KLONK image measurement software tool with linear, angular measurement. The investigated radiographs were collected from the records of SRM Dental College, Department of Oral Medicine and Radiology. Radiographs with any pathology, facial deformities, if no observation of mental foramen, congenital deformities, magnification, and distortion were excluded. Results: Mean, median, standard deviation, derived to check the first and third quartile, linear regression is used to check age and gender correlation with angle of mandible, height and width of the ramus of mandible. Conclusion: The radiographic method is a simpler and cost-effective method of age identification compared with histological and biochemical methods. Mandible is strongest facial bone after the skull, pelvic bone. It is validatory to predict age and gender by many previous studies. Radiographic and tomographic images have become an essential aid for human identification in forensic dentistry forensic dentists can choose the most appropriate one since the validity of age and gender estimation crucially depends on the method used and its proper application.

  14. Gender Transitions in Later Life: A Queer Perspective on Successful Aging

    PubMed Central

    Fabbre, Vanessa D.

    2015-01-01

    Purpose of the Study: Most understandings of successful aging are developed within a heteronormative cultural framework, leading to a dearth of theoretical and empirical scholarship relevant to lesbian, gay, bisexual, transgender, and queer (LGBTQ) older adults. This study explores the experiences of transgender persons who contemplate or pursue a gender transition in later life in order to develop culturally diverse conceptualizations of health and wellness in older age. Design and Methods: Using the extended case method, in-depth interviews were conducted with male-to-female-identified persons (N = 22) who have seriously contemplated or pursued a gender transition past the age of 50. In addition, 170hr of participant observation was carried out at 3 national transgender conferences generating ethnographic field notes on the topics of aging and gender transitions in later life. Results: Interpretive analyses suggest that many transgender older adults experience challenges to their gender identities that put their emotional and physical well-being at risk. Contemporary queer theory is used to understand these experiences and argue that greater attention to experiences of queer “failure” and negotiating “success on new terms” may be integral aspects of growth and development for transgender older adults. Implications: The Baby Boom generation is aging in a post-Stonewall, LGBTQ civil rights era, yet gerontology’s approach to gender and sexual identity has largely been formulated from a heteronormative perspective. A framework for understanding older transgender persons’ experiences informed by queer theory offers a new orientation for conceptualizing successful aging in the lives of marginalized gender and sexual minorities.

    While stereotypes about gender, race, and age (particularly old age) have been studied independently, few have examined the content of compound stereotypes that consider the intersection of gender, race, and age. Using a within-subjects design, we examined stereotypes as a function of target gender (male, female), race (Black, White), and age across the life span (adolescent, young adult, middle-aged, young-old, and old-old). Participants rated 20 target groups on 10 attributes representative of either an agentic (e.g., ambitious) or communal (e.g., considerate) orientation. Participants were presented only with categorical information (e.g., Black, 85-year-old, males), and ordering of categorical information and target groups was counterbalanced across participants. We hypothesized differential effects of target gender and race as a function of age. Multivariate analyses of variance on each attribute revealed significant main effects that supported traditional stereotype research, but significant interactions revealed a more complicated picture. Overall, results showed that while gender stereotypes about agency and communion generally hold up across the life span, they are more applicable to White than Black targets. Results also supported the notion that we hold unique stereotypes based on multiple social categories rather than simply perceiving one social category as more salient than another, which was best exemplified in the case of Black female targets that were less likely to be perceived in gender stereotypic ways across the life span. We suggest stereotype research needs to shift to accommodate for the complexity and diversity of real people. PMID:26610722

    The escalating use of khat (Catha edulis) in East Africa and Arabia is a major concern for public health. Yet little is known about the impact of khat on behaviour. To that end, there has been no study in the region to assess the extent to which dependence syndrome is associated with khat use in this population. We examined in this study was psychometric properties of the Severity of Dependence Scale-Khat (SDS-khat), gender differences in patterns of khat use and dependence, and the extent to which age moderated the link between gender and khat dependence. Two-hundred and ninety-two khat chewers recruited in two Yemeni cities completed face-to-face interviews asking about demographics and patterns of khat use. Validity of SDS-khat was examined by the principle component analysis and reliability of the scale was tested by the Cronbach's alpha. A series of chi-square tests and analysis of variances (ANOVAs) were conducted to examine gender differences in khat use variables. The results indicated that the mean age of khat chewers was 30.52 years (95% CI: 29.34, 31.70) years, and 52% of them were males. The SDS-khat was found to have two factors with moderate reliability. This pattern was consistent when the analysis was conducted in the entire sample and in each gender. Male khat chewers reported more symptoms related to khat dependence than female chewers. A significant gender by age interaction in SDS-khat levels (p =0.013) revealed a positive association between age and khat dependence in women only. These results provide initial support for the use of SDS-khat in the assessment of khat dependence in Yemen. Gender differences in khat use patterns and dependence observed in this study call the need for more studies carefully examining the role of gender in khat research. PMID:25064835

Survey-weighted unadjusted and adjusted linear regressions were used to obtain mean estimates of age at diagnosis. In the adjusted regression model, ages at diagnosis were 10.5, 8.7, 8.4, and 4.2 years earlier among South Asian, Vietnamese, Filipino, and Korean populations, respectively, as compared to non-Hispanic whites; no significant difference in age at diagnosis was noted for Chinese and Japanese populations. Recommendations for diabetes screening and preventive measures specific to Asian American populations are warranted. PMID:26355827

    This article adopts an intersectional approach to investigate how age, gender, and diversity are represented, silenced, or prioritized in design. Based on a comparative study of design practices of information and communication technologies (ICTs) for young girls and older people, this article describes differences and similarities in the ways in which designers tried to cope with diversity. Ultimately diversity was neglected, and the developers relied on hegemonic views of gender and age, constructed older people and young girls as an "other," and consequently their input was neglected. These views were thus materialized in design and reinforce such views in powerful yet unobtrusive ways. PMID:26918623

    In the mid 1970s, UMTRI investigated the biomechanical properties of the head and neck using 180 "normal" adult subjects selected to fill eighteen subject groups based on age (young, mid-aged, older), gender, and stature (short, medium, and tall by gender). Lateral-view radiographs of the subjects' cervical spines and heads were taken with the subjects seated in a simulated automotive neutral posture, as well as with their necks in full-voluntary flexion and full-voluntary extension. Although the cervical spine and lower head geometry were previously measured manually and documented, new technologies have enabled computer digitization of the scanned x-ray images and a more comprehensive and detailed analysis of the variation in cervical spine and lower head geometry with subject age, stature, and gender. After scanning the radiographic images, 108 skeletal landmarks on the cervical vertebrae and 10 head landmarks were digitized. The resulting database of cervical spine and head geometry was used to study cervical spine curvature, vertebral dimensions, and head/neck orientation as functions of age, gender, and stature. The data were used to characterize neutral posture cervical spine curvatures using two methods: a curvature index and Bézier spline functions. Lateral-view vertebral dimensions were also calculated for each subject, and a cascading series of equations was developed to estimate vertebral size and shape for a selected age, stature, and gender. The orientation of the cervical spine was defined using a neck chord angle, where the neck chord was varied to use different anatomical landmarks and estimates of joint centers for the top and bottom of the neck chord. Results from the study have been incorporated into a MS-Access based software package that allows researchers and modelers to generate cervical spine geometries for occupants of a specified age, gender, and stature. The program allows selection of individual occupants from the database that meet

    Cherubism is a benign bone dysplasia of childhood, exclusively involving maxillary bones and spontaneous resolving after puberty in different grades. Approximately, 280 cases have been reviewed in the literature. It is an autosomal dominant disorder in which the normal bone is replaced by cellular fibrous and immature bone, resulting in painless symmetrical enlargement of the jaws. Diagnosis is based in clinical and radiological findings, confirmed by histology. Treatment is a controversial issue, and it is recommended surgical management as conservative as possible during the rapid growth phases. An aggressive case of cherubism is reported, diagnosed and followed since early childhood until puberty, with progressive involvement of facial bones developing in a disruption of facial contours and occlusion. The patient is treated by several surgical interventions oriented to minimize the aesthetic impact of the disease being as conservative as possible. The highlights of this case are the great proportion of the lesions, the functional and emotional disturbances brought out by these lesions and the difficulty to choose the most appropriate age and form of treatment.

    OBJECTIVE: To investigate the influence of gender and weight/gestational age ratio on the Auditory Brainstem Response (ABR) in preterm (PT) and term (T) newborns. METHODS: 176 newborns were evaluated by ABR; 88 were preterm infants - 44 females (22 small and 22 appropriate for gestational age) and 44 males (22 small and 22 appropriate for gestational age). The preterm infants were compared to 88 term infants - 44 females (22 small and 22 appropriate for gestational age) and 44 males (22 small and 22 appropriate for gestational age). All newborns had bilateral presence of transient otoacoustic emissions and type A tympanometry. RESULTS: No interaural differences were found. ABR response did not differentiate newborns regarding weight/gestational age in males and females. Term newborn females showed statistically shorter absolute latencies (except on wave I) than males. This finding did not occur in preterm infants, who had longer latencies than term newborns, regardless of gender. CONCLUSIONS: Gender and gestational age influence term infants' ABR, with lower responses in females. The weight/gestational age ratio did not influence ABR response in either groups. PMID:24473955

    This study explored the age-related deterioration in stretch-shortening cycle (SSC) muscle power and concurrent force-velocity properties in women and men across the adult life span. A total of 315 participants (women: n = 188; men: n = 127) aged 18-81 years performed maximal countermovement jumps on an instrumented force plate. Maximal SSC leg extension power expressed per kg body mass (Ppeak) was greater in men than in women across the adult age span (P < 0.001); however, this gender difference was progressively reduced with increasing age, because men showed an ∼50% faster rate of decline in SSC power than women (P < 0.001). Velocity at peak power (VPpeak) was greater in men than in women (P < 0.001) but declined at a greater rate in men than in women (P = 0.002). Vertical ground reaction force at peak power (FPpeak) was higher in men than in women in younger adults only (P < 0.001) and the age-related decline was steeper in men than in women (P < 0.001). Men demonstrated a steeper rate of decline in Ppeak than women with progressive aging. This novel finding emerged as a result of greater age-related losses in men for both force and velocity. Consequently, maximal SSC power production was observed to converge between genders when approaching old age. PMID:23551758

    ADHD is known to have neuropsychological correlates, characterized mainly by executive function (EF) deficits. However, most available data are based on studies of boys through age 12. Our goal was to assess whether girls with ADHD express neuropsychological features similar to those found in boys, and whether these impairments are found in both preteen and teen samples. Participants were 101 girls and 103 boys with DSM-III-R ADHD, and 109 comparison girls and 70 boys without ADHD, ages 9 to 17 years. Information on neuropsychological performance was obtained in a standardized manner blind to clinical status. Primary regression analyses controlled for age, socioeconomic status, learning disability, and psychiatric comorbidity. Girls and boys with ADHD were significantly more impaired on some measures of EFs than healthy comparisons but did not differ significantly from each other. With the exception of 1 test score there were no significant Sex x Diagnosis interactions. Moreover, there were no more significant interactions among age, gender, and diagnosis than would be expected by chance. Neuropsychological measures of EFs were comparably impaired in girls compared to boys with ADHD, and these impairments are found at ages 9 to 12 and ages 13 to 17. These findings suggest that executive dysfunctions are correlates of ADHD regardless of gender and age, at least through the late teen years. PMID:15737943

Study 1 consisted of 73 mothers of firstborn term girls and boys queried at 2, 5, and 13 months of age. Study 2 consisted of 335 mothers of infants of different gender, birth order, term status, and SES queried at 6 and 12 months. Consistent positive and negative affectivity factors emerged at all time-points across both studies. Infant temperament proved stable and robust across gender, birth order, term status, and SES. Stability coefficients for temperament factors and scales were medium to large for shorter (<9 months) inter-assessment intervals and small to medium for longer (>10 months) intervals. PMID:25865034

    Although neuropathic pain is increasingly recognized in sickle cell disease (SCD), it is unknown how neuropathic pain drugs are used in children with SCD. Thus, we investigated use of these drugs and hypothesized older age and female gender are associated with increased neuropathic drug use and the use of these drugs is associated with longer length of stay. We analyzed the Pediatric Health Information System (2004-09) including all inpatient visits 0-18 years with any SCD-related (all genotypes) discharge diagnosis. To limit confounding we excluded psychiatric and seizure visits. Antiepileptics, tricyclic antidepressants, and selective serotonin reuptake inhibitors were drugs of interest. Generalized Estimating Equations determined the impact of age and gender on neuropathic drug use and the impact of neuropathic drug use on length of stay. We analyzed 53,557 visits; 2.9% received ≥1 neuropathic drugs. The odds of receiving a neuropathic drug increased significantly with age [Reference group 0-4 yrs: 5-10, OR 5.7; 11-14, OR 12.5; 15-18, OR 22.8; all p<0.0001] and female gender [OR 1.5; p=0.001)]. Neuropathic drug use was associated with longer length of stay [RR 8.3; p<0.0001]. Neuropathic drug use in children with SCD was associated with older age, female gender, and longer length of stay.

    Data showing a remarkable gender difference in life expectancy and mortality, including survival to extreme age, are reviewed starting from clinical and demographic data and stressing the importance of a comprehensive historical perspective and a gene–environment/lifestyle interaction. Gender difference regarding prevalence and incidence of the most important age-related diseases, such as cardiovascular and neurodegenerative diseases, cancer, Type 2 diabetes, disability, autoimmunity and infections, are reviewed and updated with particular attention to the role of the immune system and immunosenescence. On the whole, gender differences appear to be pervasive and still poorly considered and investigated despite their biomedical relevance.

    Data showing a remarkable gender difference in life expectancy and mortality, including survival to extreme age, are reviewed starting from clinical and demographic data and stressing the importance of a comprehensive historical perspective and a gene-environment/lifestyle interaction. Gender difference regarding prevalence and incidence of the most important age-related diseases, such as cardiovascular and neurodegenerative diseases, cancer, Type 2 diabetes, disability, autoimmunity and infections, are reviewed and updated with particular attention to the role of the immune system and immunosenescence. On the whole, gender differences appear to be pervasive and still poorly considered and investigated despite their biomedical relevance. The basic biological mechanisms responsible for gender differences in aging and longevity are quite complex and still poorly understood. The present review focuses on centenarians and their offspring as a model of healthy aging and summarizes available knowledge on three basic biological phenomena, i.e. age-related X chromosome inactivation skewing, gut microbiome changes and maternally inherited mitochondrial DNA genetic variants. In conclusion, an appropriate gender-specific medicine approach is urgently needed and should be systematically pursued in studies on healthy aging, longevity and age-related diseases, in a globalized world characterized by great gender differences which have a high impact on health and diseases.

    Xue, Joel; Farrell, Robert M

    2014-01-01

    It is well known that there are gender differences in 12 lead ECG measurements, some of which can be statistically significant. It is also an accepted practice that we should consider those differences when we interpret ECGs, by either a human overreader or a computerized algorithm. There are some major gender differences in 12 lead ECG measurements based on automatic algorithms, including global measurements such as heart rate, QRS duration, QT interval, and lead-by-lead measurements like QRS amplitude, ST level, etc. The interpretation criteria used in the automatic algorithms can be adapted to the gender differences in the measurements. The analysis of a group of 1339 patients with acute inferior MI showed that for patients under age 60, women had lower ST elevations at the J point in lead II than men (57±91μV vs. 86±117μV, p<0.02). This trend was reversed for patients over age 60 (lead aVF: 102±126μV vs. 84±117μV, p<0.04; lead III: 130±146μV vs. 103±131μV, p<0.007). Therefore, the ST elevation thresholds were set based on available gender and age information, which resulted in 25% relative sensitivity improvement for women under age 60, while maintaining a high specificity of 98%. Similar analyses were done for prolonged QT interval and LVH cases. The paper uses several design examples to demonstrate (1) how to design a gender-specific algorithm, and (2) how to design a robust ECG interpretation algorithm which relies less on absolute threshold-based criteria and is instead more reliant on overall morphology features, which are especially important when gender information is unavailable for automatic analysis.

    2015-06-15

    Highlights: • An effect of gender and age structure on municipal waste generation was presented. • The waste accumulation index is influenced by a number of unemployed women. • Greater share of women in society contributes to greater waste production. • A model describing the analyzed dependences was determined. - Abstract: In this study the effect of gender and age structure on municipal waste generation was investigated. The data from 10-year period, from 2001 to 2010 year, were taken into consideration. The following parameters of gender and age structure were analyzed: men and woman quantity, female to male ratio, number of working, pre-working and post-working age men/women, number of unemployed men/women. The results have showed a strong correlation of annual per capita waste generation rate with number of unemployed women (r = 0.70) and female to male ratio (r = 0.81). This indicates that waste generation rate is more depended on ratio of men and women that on quantitative size of each group. Using the regression analysis a model describing the dependence between female to male ratio, number of unemployed woman and waste quantity was determined. The model explains 70% of waste quantity variation. Obtained results can be used both to improve waste management and to a fuller understanding of gender behavior.

    Viscoelasticity is a sensitive measure of the microstructural constitution of soft biological tissue and is increasingly used as a diagnostic marker, e.g. in staging liver fibrosis or characterizing breast tumors. In this study, multifrequency magnetic resonance elastography was used to investigate the in vivo viscoelasticity of healthy human brain in 55 volunteers (23 females) ranging in age from 18 to 88 years. The application of four vibration frequencies in an acoustic range from 25 to 62.5 Hz revealed for the first time how physiological aging changes the global viscosity and elasticity of the brain. Using the rheological springpot model, viscosity and elasticity are combined in a parameter mu that describes the solid-fluid behavior of the tissue and a parameter alpha related to the tissue's microstructure. It is shown that the healthy adult brain undergoes steady parenchymal 'liquefaction' characterized by a continuous decline in mu of 0.8% per year (P<0.001), whereas alpha remains unchanged. Furthermore, significant sex differences were found with female brains being on average 9% more solid-like than their male counterparts rendering women more than a decade 'younger' than men with respect to brain mechanics (P=0.016). These results set the background for using cerebral multifrequency elastography in diagnosing subtle neurodegenerative processes not detectable by other diagnostic methods. PMID:19281851

    Schlebusch, Lourens; Govender, Romona Devi

    2012-02-01

    The aim of this study was to determine the prevalence of suicidal ideation in patients who were tested for HIV-infection and whether along with their HIV status, age and gender influenced their risk for suicidal ideation. The sample consisted of 189 patients who attended a voluntary HIV counseling and testing clinic (VCT) at a general state hospital in Durban, South Africa. Their mean age at baseline was 34.2 years, with an age range of between 16-79 years. Seropositivity, age and gender were significantly associated with suicidal ideation. The majority of these patients were in the younger age group, and young males had a 1.8 times higher risk for suicidal ideation than females. Although risk factors for seropositive-related suicidal ideation can be complex and multi-factorial, this study identified a young age and male gender as important high risk factors in the sample studied. It is recommended that all, but especially young male HIV-infected patients seen at a VCT clinic be screened for suicidal ideation and that early intervention to prevent subsequent suicides or suicidal attempts be included in pre- and post-test HIV counseling.

    Cognitive skills decline with age. Our ability to keep oriented in our surrounding environment was demonstrated to be influenced by factors like age and gender. Introduction of virtual reality based tasks improved assessment of spatial memory in humans. In this study, spatial orientation was assessed in a virtual memory task in order to determine the effect of aging and gender on navigational skills. Subjects from 45 to 74 years of age were organized in three groups (45-54, 55-64, 65-74 years old). Two levels of difficulty were considered. Results showed that males outperformed females in 65-74 years-old group. In addition to this, females showed a more noticeable poor performance in spatial memory than males, since memory differences appeared between all age groups. On the other hand, 65-74 year-old males showed an impaired performance in comparison with 45-54 year-old group. These results support that spatial memory becomes less accurate as we age and gender is an important factor influencing spatial orientation skills. PMID:26965569

    The goal of the current investigation was to analyze ability emotional intelligence (EI) in a large cross-sectional sample of Spanish adults (N = 12,198; males, 56.56%) aged from 17 to 76 years (M = 37.71, SD = 12.66). Using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), which measures ability EI according to the 4 branches of the Mayer and Salovey EI model. The authors examined effects of gender on ability EI, as well as the linear and quadratic effects of age. Results suggest that gender affects the total ability EI score as well as scores on the 4 EI branches. Ability EI was greater in women than men. Ability EI varied with age according to an inverted-U curve: Younger and older adults scored lower on ability EI than middle-aged adults, except for the branch of understanding emotions. These findings strongly support the idea that both gender and age significantly influence ability EI during aging. (PsycINFO Database Record PMID:27570984

    Urinary tract infections (UTIs) are among the most frequent community-acquired infections worldwide. Escherichia coli is the most common UTI pathogen although underlying host factors such as patients' age and gender may influence prevalence of causative agents. In this study, 61 273 consecutive urine samples received over a 22-month period from outpatients clinics of an urban area of north Italy underwent microbiological culture with subsequent bacterial identification and antimicrobial susceptibility testing of positive samples. A total of 13 820 uropathogens were isolated and their prevalence analyzed according to patient's gender and age group. Overall Escherichia coli accounted for 67.6% of all isolates, followed by Klebsiella pneumoniae (8.8%), Enterococcus faecalis (6.3%), Proteus mirabilis (5.2%), and Pseudomonas aeruginosa (2.5%). Data stratification according to both age and gender showed E. coli isolation rates to be lower in both males aged ≥60 years (52.2%), E. faecalis and P. aeruginosa being more prevalent in this group (11.6% and 7.8%, resp.), as well as in those aged ≤14 years (51.3%) in whom P. mirabilis prevalence was found to be as high as 21.2%. Streptococcus agalactiae overall prevalence was found to be 2.3% although it was shown to occur most frequently in women aged between 15 and 59 years (4.1%). Susceptibility of E. coli to oral antimicrobial agents was demonstrated to be as follows: fosfomycin (72.9%), trimethoprim/sulfamethoxazole (72.9%), ciprofloxacin (76.8%), ampicillin (48.0%), and amoxicillin/clavulanate (77.5%). In conclusion, both patients' age and gender are significant factors in determining UTIs etiology; they can increase accuracy in defining the causative uropathogen as well as providing useful guidance to empiric treatment.

    Increasing numbers of climbers are attempting Mount Everest, the highest mountain on Earth. We compiled interview data and computed the probabilities of summiting and of dying as a function of climber age and gender (2211 climbers, spring season) for the period of 1990-2005. Men and women had similar odds of summiting and of dying. However, climbers older than 40 years have reduced odds of summiting, and those older than 60 years have increased odds of dying, especially when descending from the summit. On Mount Everest, phenotypic selection appears blind to gender but favours young mountaineers. PMID:17698450

    Background Body weight (BW) and age have been shown to affect the dose of levothyroxine (LT4) that results in normalization of serum thyroid-stimulating hormone (TSH) in hypothyroid patients. Our objective was to determine whether gender, menstrual status, and ideal BW (IBW) also affect the LT4 dose required to achieve a serum TSH within the normal range. Methods We retrospectively reviewed the charts of patients being treated for primary hypothyroidism who had TSH values within a normal range. We selected patients aged 18–85 years who were taking LT4 without any confounding medications, and who had no serious chronic conditions. Their LT4 doses, referred to here as LT4 dose requirements, based on both BW and IBW were documented. The relationship between gender, menstrual status, age, serum TSH concentrations, and the degree of overweight on LT4 dose requirements were determined using multivariate analyses. Results Women were significantly more overweight than men (ratio of BW/IBW was 1.35 for women vs. 1.17 for men, p < 0.0001). LT4 requirements based on BW did not differ by gender when age was included in the model. However, when degree of overweight was also included, men required lower LT4 doses than both premenopausal women (1.34 μg/kg vs. 1.51 μg/kg, p = 0.038) and menopausal women (1.34 μg/kg vs. 1.49 μg/kg, p = 0.023). When examining IBW using a model incorporating age, men also required lower LT4 doses than both premenopausal women (1.64 μg/kg vs. 1.92 μg/kg, p = 0.0033) and menopausal women (1.64 μg/kg vs. 1.90 μg/kg, p = 0.0024). Serum TSH concentrations were not significantly different in any of the gender groups. There was no relationship between serum TSH and either age or BW. The initial serum TSH concentration was by design with the normal range, but the concentration within that range was not a significant predictor of the LT4 replacement dose in any of the models. Conclusion In contrast to previous

    The age at which gender dysphoria can be diagnosed with enough certainty to justify medical intervention is controversial. The aim of this article is to explore current literature as it relates to the gender reassignment process and diagnostic indicators supporting an appropriate age for intervention. The timing of diagnosis and treatment of gender dysphoria remains the center of debate between the long-term effects of early intervention versus delay of treatment. Limited research is available on gender dysphoria treatment protocols for children. However, preliminary studies suggest that early intervention improves the quality of life in individuals who are transgender. Ongoing research suggests that it may be possible to confirm gender dysphoria at an earlier age. PMID:24972388

    Data from the Children in the Community Transitions Study were used to examine gender differences in the impact of family contact on the development of finance and romance instrumentality from ages 17 to 27 years. Family contact decreased among both men and women across emerging adulthood, although it decreased more rapidly in men than in women. Both finance and romance instrumentality increased for men and women across emerging adulthood. The growth rate did not differ between men and women in either domain, although men tended to be characterized by higher levels of instrumentality than women. There were noteworthy gender differences in the impact of family contact on the development of instrumentality. At age 17, family contact was negatively associated with instrumentality for both men and women; at age 27, the impact of family contact on instrumentality was less negative for women and was positive for men.

    The purpose of the study was to (a) investigate gender and age differences in physical aggression, verbal aggression, anger, and hostility, and (b) examine the discriminatory power of the Greek version of the Aggression Questionnaire (GAQ) with high school students. The sample of the study consisted of 658 high school students (321 boys and 337 girls), with an age range from 13 to 17 years (M = 15.3, SD = 1.5). The students completed the Aggression Questionnaire adapted to Greek. Regarding gender, the overall correct identification rate in the discriminant analysis showed that 73.3% of the cases were correctly classified. In addition, the results indicated that physical aggression declined with age and that, compared to boys, girls of higher grades apply more indirect forms of aggression, such as anger and hostility. The findings of the study provide important information regarding the expression of aggressive behavior during adolescence. PMID:23262821

    This paper is based on data from focus group discussions and in-depth individual interviews carried out in two slum areas, Korogocho and Viwandani in Nairobi, Kenya. It discusses how the division between domestic sphere and public sphere impacts on survival during, and adaptation to old age. Although this paper adopts some of the tenets of the life course approach, it posits that women's participation in the domestic sphere may sometimes give them a ‘gender advantage’ over men in terms of health and adaptation to old age. The paper also discusses the impact of gender roles on the cultivation of social networks and how these networks in turn impact on health and social adjustment as people grow older. It investigates how older people are adjusting and coping with the new challenges they face as a result of high morbidity and mortality among adults in the reproductive age groups. PMID:19907648

    This study focused on age-related changes in visual short-term memory using visual stimuli that did not allow verbal encoding. Experiment 1 examined the effects of age and the length of the stimulus presentation period on visual short-term memory function. Experiment 2 examined the effects of age, gender, and the length of the stimulus presentation period on visual short-term memory function. The worst memory performance and the largest performance difference between the age groups were observed in the shortest stimulus presentation period conditions. The performance difference between the age groups became smaller as the stimulus presentation period became longer; however, it did not completely disappear. Although gender did not have a significant effect on d' regardless of the presentation period in the young group, a significant gender-based difference was observed for stimulus presentation periods of 500 ms and 1,000 ms in the older group. This study indicates that the decline in visual short-term memory observed in the older group is due to the interaction of several factors. PMID:26745456

    Study Design: Retrospective, 3-year case series. Objective: To investigate the relationship between gender and age and a range variables in patients with nontraumatic spinal cord injury (SCI). Setting: Tertiary medical unit specializing in rehabilitation of patients with nontraumatic SCI. Method: Participants were a consecutive series of 70 adult inpatients with nontraumatic SCI undergoing initial rehabilitation. The variables of interest were demographic characteristics, clinical features, complications, mortality, length of stay (LOS), mobility, bladder and bowel continence, and Functional Independence Measure (FIM) scores. Results: Men were younger than women, but the difference was not statistically significant (median 64 years vs 72.5 years, P =0.2). There was no statistically significant relationship between age or gender and the following: American Spinal Injury Association grade, level of injury, many SCI complications, mortality, LOS, walking ability, bladder management, and fecal continence. The only SCI complication that was related to age was pressure ulcers (<65 years = 20% vs ≥65 years = 50%, P = 0.04). Patients discharged home were more likely to be younger (P = 0.01) and male (P = 0.03). There was a significant negative correlation between patients' age and the discharge Rasch-transformed FIM motor (Spearman's ρ =−0.30, P = 0.015) and cognitive (Spearman's ρ =−0.25, P = 0.04) subscores. There were no significant relationships between gender and FIM subscale scores. Conclusions: Gender and age do not significantly influence most aspects of rehabilitation in patients with nontraumatic SCI. Age alone should not be used as a discriminator of ability to benefit from nontraumatic SCI rehabilitation. PMID:17684888

    2015-01-01

    We compare selected European countries using an economic dependency ratio which emphasizes the role of age-specific levels of production and consumption. Our analysis reveals large differences in the age- and gender-specific level and type of production activities across selected European countries and identifies possible strategies to adjust age-specific economic behaviour to an ageing population. The cross-country differences in economic dependency of children and elderly persons are largely determined by the age at which people enter, respectively exit, the labour market. The ability of the working age population to support children and elderly persons in turn is strongly influenced by the participation of women in paid work. We also provide a measure for the age-specific production and consumption in form of unpaid household work. The inclusion of unpaid household work leads to a decrease of the gender differences in production activities and indicates that the working age population supports children and elderly persons not only through monetary transfers but also through services produced by unpaid work (e.g. childcare, cooking, cleaning…). Given the available data, we cannot distinguish the age profile of consumption by gender and have to assume – in case of unpaid work - that each member of the household consumes the same. Hence, our results have to be regarded as a first approximation only. Our paper aims to argue that a reform of the welfare system needs to take into account not only public transfers but also private transfers, in particular the transfers in form of goods and services produced through unpaid household work.

    Concepts of time are ubiquitous in studies of aging. This article integrates an existential perspective on time with a notion of queer time based on the experiences of older transgender persons who contemplate or pursue a gender transition in later life. Interviews were conducted with male-to-female identified persons aged 50 years or older (N=22), along with participant observation at three national transgender conferences (N=170 hours). Interpretive analyses suggest that an awareness of “time left to live” and a feeling of “time served” play a significant role in later life development and help expand gerontological perspectives on time and queer aging.

    Two modes of inheritance have been proposed in autism spectrum disorder, transmission though pre-existing variants and de novo mutations. Different modes may lead to different symptom expressions in affected individuals. De novo mutations become more likely with advancing paternal age suggesting that paternal age may predict phenotypic differences. To test this possibility we measured IQ, adaptive behavior, and autistic symptoms in 830 probands from simplex families. We conducted multiple linear regression analysis to estimate the predictive value of paternal age, maternal age, and gender on behavioral measures and IQ. We found a differential effect of parental age and sex on repetitive and restricted behaviors. Findings suggest effects of paternal age on phenotypic differences in simplex families with ASD.

    Serum transthyretin (TTR) levels are reduced in familial amyloidotic polyneuropathy (FAP). A single study of patients with senile systemic amyloidosis (SSA) in Sweden found that those individuals also had a significantly lower mean serum TTR concentration than age- and gender-matched controls. To determine if the same phenomenon prevailed in an ethnically more heterogeneous population, we compared the serum TTR levels, as determined by ELISA, in 45 documented SSA patients with congestive heart failure, 20 AL patients with congestive heart failure and population controls. Serum TTR concentrations in the controls were influenced in a statistically significant manner by age, gender and ethnicity. Although it is unlikely that such differences are clinically relevant, they must be considered when assessing the meaning of serum TTR concentrations in any clinically defined population. The serum concentrations in patients with SSA did not differ from age, gender and ethnically matched controls or from a group of AL patients with significant clinical cardiac involvement. We also compared TTR concentrations in 12 African-Americans carrying the TTR V122I allele with those in 826 African-Americans who were homozygous wild type at the TTR locus. The TTR V122I carriers had significantly lower serum TTR concentrations than appropriate controls even though the majority of such individuals had not reached the age of clinical or anatomic risk, i.e. over 60. Thus, as in carriers of other TTR mutations the serum TTR level is lower than normal, despite having a much later appearance of clinical disease. PMID:19065297

    Skin ageing and gender influences on the scalp have been seldom studied. We revisited the changes in the interfollicular scalp. The study was performed on a population of 650 volunteers (300 women and 350 men) for over 7 years. Three age groups were selected in both genders, namely, subjects aged 20-35, 50-60, and 60-70 years. The hair status was further considered according to nonalopecic and alopecic patterns and severity (discrete, moderate, and severe). Biopsies from the parietal area were processed for immunohistochemistry. Stromal cells were distinguished according to the presence of vimentin, Factor XIIIa, CD117, and versican. Blood and lymphatic vessels were highlighted by Ulex europaeus agglutinin-1 and human podoplanin immunoreactivities, respectively. Actinic elastosis was identified by the lysozyme coating of elastic fibres. The epidermis was explored using the CD44 variant 3 and Ki67 immunolabellings. Biplot analyses were performed. Immunohistochemistry revealed a prominent gender effect in young adults. Both Factor XIIIa+ dermal dendrocytes and the microvasculature size decreased with scalp ageing. Alopecia changes mimicked stress-induced premature senescence. PMID:24455724

    The results of previous investigations indicate that age and gender may influence the strength of the human host's immune response to infection of the central nervous system with the larvae of Taenia solium. Most of the relevant research on such neurocysticercosis (NCC) has, however, been conducted on hospital-based samples in developing countries, where differential access to healthcare may bias the study results. Using data from 171 NCC patients participating in a treatment trial, the associations of patient age and gender with the presence of inflammation around NCC cysts (i.e. cysts in the transitional phase) have recently been explored, after controlling for measures of economic and geographical access to healthcare. Data on cysts were collected from computed-tomography or magnetic-resonance images taken at four time-points, from baseline to 12-months post-treatment. The odds of having transitional cysts were evaluated by logistic regression whereas Poisson regression was used to explore the numbers of transitional cysts, with generalised estimating equations (GEE) used to account for the multiple observations over time. After controlling for healthcare access, the odds of having transitional cysts were found to be 1.5-fold higher for the female patients than for the male, although this association was not statistically significant (P = 0.136). In the Poisson model, however, the number of transitional cysts was found to be 1.8-fold higher in the female patients than in the male, and this gender effect was not only statistically significant (P = 0.002) but also constant over time. The association of host age with transitional cysts was more complicated, with significant interaction between age and time. It therefore appears that there are significant gender and age differences in the local immune response to NCC, even after adjusting for differences in healthcare access. PMID:19695154

    Purpose To compare mortality rates from motor vehicle accidents (MVA), homicide, and suicide across countries, age groups, and time. Methods The World Health Organization Mortality Database was used to construct age- and gender-specific rates in 26 countries for individuals aged 15 to 34 years during the period 1955 to 1994. The rates were adjusted for differences among countries in the age-and-gender distributions of their populations. Cause-specific rates were compared by country, 4-year age groups, 8-year time blocks, and male/female ratios. Results The proportion of deaths in 15–34-year-olds owing to MVA, homicide, and suicide increased from 26% to 43% over the 40-year study period. Mortality rates differ by country more than time block, peak at ages 15–29 years, and are higher in males than females. Compared to the United States, 24 countries had lower homicide rates and 23 had lower MVA-death rates. Conclusions Despite declining rates of death from other causes, the rates of adolescent and young adult death from MVA, homicide, and suicide remain high in countries throughout the world. The proportion of deaths attributable to these causes increased steadily during the latter half of the 20th century. Fatal risk behaviors begin to increase during adolescence but do not peak until age 30 years, suggesting that the target population for prevention extends well beyond the teenage years.

    Brain lateralization is a widely studied topic, however there has been little work focused on lateralization of intrinsic networks (regions showing similar patterns of covariation among voxels) in the resting brain. In this study, we evaluate resting state network lateralization in an age and gender-balanced functional magnetic resonance imaging (fMRI) dataset comprising over 600 healthy subjects ranging in age from 12 to 71. After establishing sample-wide network lateralization properties, we continue with an investigation of age and gender effects on network lateralization. All data was gathered on the same scanner and preprocessed using an automated pipeline (Scott et al., 2011). Networks were extracted via group independent component analysis (gICA) (Calhoun, Adali, Pearlson, & Pekar, 2001). Twenty-eight resting state networks discussed in previous (Allen et al., 2011) work were re-analyzed with a focus on lateralization. We calculated homotopic voxelwise measures of laterality in addition to a global lateralization measure, called the laterality cofactor, for each network. As expected, many of the intrinsic brain networks were lateralized. For example, the visual network was strongly right lateralized, auditory network and default mode networks were mostly left lateralized. Attentional and frontal networks included nodes that were left lateralized and other nodes that were right lateralized. Age was strongly related to lateralization in multiple regions including sensorimotor network regions precentral gyrus, postcentral gyrus and supramarginal gyrus; and visual network regions lingual gyrus; attentional network regions inferior parietal lobule, superior parietal lobule and middle temporal gyrus; and frontal network regions including the inferior frontal gyrus. Gender showed significant effects mainly in two regions, including visual and frontal networks. For example, the inferior frontal gyrus was more right lateralized in males.

    The purpose of this study is to examine the impact that gender and age differences have on the communication media selection within the context of small and medium tourism enterprises (SMEs). Media Richness Theory (MRT) was used to assess media preferences in the firms. Using a mail questionnaire, data from 78 firms were collected on seven popular media in use. Historical data of the firms, media characteristics, and other firm-specific factors were included in the analysis. The results indicated that there are substantial gender and age differences in term of communication media selection. This is consistent with MRT and highlights the importance of choosing the appropriate media in SMEs, according with the employee's behaviors, in order to achieve better outcomes and to smooth the path towards good performance in the future.

The most commonly suggested coping strategy was telling someone, especially parents and teachers (70.5%). Surprisingly few of the pupils reported that they would tell a friend (2.6%). Differences in suggested coping strategies were found related to age and gender. Findings are discussed in relation to the Swedish sociocultural context as well as in relation to the implications for prevention strategies against cyberbullying. PMID:25040330

    Parenting practices, age, and gender all influence adolescent delinquency and drug use, but few studies have examined how these factors interact to affect offending. Using data from 18,512 students in Grades 6, 8, 10 and 12, this study found that across grades, parents treated girls and boys differently, but neither sex received preferential treatment for all practices assessed, and younger children reported more positive parenting than older students. Family factors were significantly related to delinquency and drug use for both sexes and for all grades. However, particular parenting practices showed gender and age differences in the degree to which they were related to outcomes, which indicates complexities in parent/child interactions that must be taken into account when investigating the causes of adolescent offending and when planning strategies to prevent the development of problem behaviors.

    Humanitarian aid remains largely driven by anecdote rather than by evidence. The contemporary humanitarian system has significant weaknesses with regard to data collection, analysis, and action at all stages of response to crises involving armed conflict or natural disaster. This paper argues that humanitarian actors can best determine and respond to vulnerabilities and needs if they use sex- and age-disaggregated data (SADD) and gender and generational analyses to help shape their assessments of crises-affected populations. Through case studies, the paper shows how gaps in information on sex and age limit the effectiveness of humanitarian response in all phases of a crisis. The case studies serve to show how proper collection, use, and analysis of SADD enable operational agencies to deliver assistance more effectively and efficiently. The evidence suggests that the employment of SADD and gender and generational analyses assists in saving lives and livelihoods in a crisis. PMID:23905768

    Automated human identification by their walking behavior is a challenge attracting much interest among machine vision researchers. However, practical systems for such identification remain to be developed. In this study, a machine learning approach to understand human behavior based on motion imagery was proposed as the basis for developing pedestrian safety information systems. At the front end, image and video processing was performed to separate foreground from background images. Shape-width was then analyzed using 2D discrete wavelet transformation to extract human motion features. Finally, an adaptive boosting (AdaBoost) algorithm was performed to classify human gender and age into its class. The results demonstrated capability of the proposed systems to classify gender and age highly accurately.

    Handwritten signature is one of the most natural biometrics, the study of human physiological and behavioral patterns. Behavioral biometrics includes signatures that may be different due to its owner gender or age because of intrinsic or extrinsic factors. This paper presents the results of the author's research on age and gender influence on verification factors. The experiments in this research were conducted using a database that contains signatures and their associated metadata. The used algorithm is based on the universal forgery feature idea, where the global classifier is able to classify a signature as a genuine one or, as a forgery, without the actual knowledge of the signature template and its owner. Additionally, the reduction of the dimensionality with the MRMR method is discussed.

    Objective: The research assessed the attitudes and behaviors of pet owners pertaining to online search behavior for pet health information. Methods: A survey was conducted with a random sample of pet owners drawn from two US metropolitan areas and surrounding cities. Participating clinics were chosen randomly, and each participating clinic was asked to distribute 100 surveys to their clients until all surveys were disbursed. Results: Although some perceptions and behaviors surrounding the use of the Internet for pet health information differ based on gender, age, or education level of pet owners, there are many aspects in which there are no differences based on these demographics. Conclusions: Results of the study suggest that closer examination of the common perception that gender, age, or education level has an effect on Internet behavior as it relates to veterinary medicine is required. Recommendations are made pertaining to the growing presence of the Internet and its impact on veterinary medicine. PMID:22879809

    Background: Diffusion-weighted magnetic resonance imaging (DWI) systems are very effective in detecting strokes, and they also have shown significant promise in the detection of fibrosis and cirrhosis of the liver. However, such systems have the disadvantages of poor reproducibility and noise, which can diminish the accuracy of the apparent diffusion coefficients (ADCs) provided by the DWI process. The main aim of this study was to determine the relationship between the age and gender of healthy adults in terms of the ADC values of the spleen measured by DWI. Methods: Sixty-nine subjects selected for this study from people who were referred to the Tabesh Medical Imaging Center in Tabriz, Iran, in 2013. Each subject underwent echo-planar DWI for her or his ADC values of the spleen with b-values of 50, 400, and 800 s/mm2, and the resulting ADC values were evaluated. Results: No significant differences were observed in ADC values of the spleen among the female and male participants or those from various ages (P>0.05). Conclusions: Based on the findings of this study, it was concluded that the effect of age and gender on the spleen’s ADC values can be omitted from the spleen-diagnosis procedure. In other words, the spleen’s ADC values are not related to the age or the gender of healthy adults. PMID:26052412

    The third versions of the guideline for treatment of people with gender identity disorder (GID) of the Japanese Society of Psychiatry and Neurology does not include puberty-delaying hormone therapy. It is recommended that feminizing/masculinizing hormone therapy and genital surgery should not be carried out until 18 year old and 20 year old, respectively. On the other hand, the sixth (2001) and the seventh (2011) versions of the standards of care for the health of transsexual, transgender, and gender nonconforming people of World Professional Association for Transgender Health (WPATH) recommend that transsexual adolescents (Tanner stage 2, [mainly 12-13 years of age]) are treated by the endocrinologists to suppress puberty with gonadotropin-releasing hormone (GnRH) agonists until age 16 years old, after which cross-sex hormones may be given. A questionnairing on 181 people with GID diagnosed in the Okayama University Hospital (Japan) showed that female to male (FTM) transsexuals hoped to begin masculinizing hormone therapy at age of 15.6 +/- 4.0 (mean +/- S.D.) whereas male to female (MTF) transsexuals hoped to begin feminizing hormone therapy as early as age 12.5 +/- 4.0, before presenting secondary sex characters. After confirmation of strong and persistent cross-gender identification, adolescents with GID should be treated with cross-gender hormone or puberty-delaying hormone to prevent developing undesired sex characters. These treatments may prevent transsexual adolescents from attempting suicide, being depressive, and refusing to attend school. Subsequent early breast and genital surgery may help being employed in desired sexuality. PMID:22844815

    The aim of this study was to determine the effects of selection, educational background, age and gender on strength of motivation to attend and pursue medical school. Graduate entry (GE) medical students (having Bachelor's degree in Life Sciences or related field) and Non-Graduate Entry (NGE) medical students (having only completed high school), were asked to fill out the Strength of Motivation for Medical School (SMMS) questionnaire at the start of medical school. The questionnaire measures the willingness of the medical students to pursue medical education even in the face of difficulty and sacrifice. GE students (59.64 ± 7.30) had higher strength of motivation as compared to NGE students (55.26 ± 8.33), so did females (57.05 ± 8.28) as compared to males (54.30 ± 8.08). 7.9% of the variance in the SMMS scores could be explained with the help of a linear regression model with age, gender and educational background/selection as predictor variables. Age was the single largest predictor. Maturity, taking developmental differences between sexes into account, was used as a predictor to correct for differences in the maturation of males and females. Still, the gender differences prevailed, though they were reduced. Pre-entrance educational background and selection also predicted the strength of motivation, but the effect of the two was confounded. Strength of motivation appears to be a dynamic entity, changing primarily with age and maturity and to a small extent with gender and experience. PMID:19774476

    The purpose of this study was to analyze the anthropometric data from MRI images that were obtained from the non-arthritic knees in Asian adults, and to identify the existence of morphologic differences between age groups. This cross-sectional study included knee MR images of 535 patients (273 males, 262 females) taken for the evaluation of soft-tissue injuries, excluding cases with cartilage defect and malalignment. The age, gender, height, and BMI were also assessed. The patients were grouped into three different 20-year age groups (20-39, 40-59, and 60-79). The MRI analysis was performed on the anthropometric parameters of distal femur and posterior tibial slope. Age-related differences were found in femoral width, distance from the distal and posterior cartilage surface to the medial/lateral epicondyle, medial posterior condylar offset (PCO), and posterior condylar angle (PCA) (all P < 0.001), but not in lateral PCO, and medial/lateral tibial slopes. In the analysis of covariance analyses, significant interaction between gender and age groups was found in most parameters, but not in PCA, distance from the posterior cartilage surface to the medial epicondyle, or medial tibial slope. We found anthropometric differences among age groups exist in most of distal femoral parameters, but not in posterior tibial slope. The results of this study can be used by manufacturers to modify prostheses to be suitable for the future Asian elderly population. PMID:26253858

    This work is part of a qualitative socio-cultural investigation with a group of men and women 40 years and older in the maquila export industry in Nogales, Sonora, Mexico. In 1994, as a result of the North American Free Trade Agreement, maquila plants combined traditional intensive work methods with new "just in time" production norms that impacted work and health conditions, particularly in older, or aging, workers. The workers that were interviewed for this study show a reduction in their functional ability to work starting at 40 years of age. Work organization demands, general health conditions, and a decrease in physical abilities brings these 40-year-old workers to prematurely construct an image of themselves as aging workers and to develop coping strategies that vary by gender.

    We investigated how visual experience with faces of a particular race affects subordinate group-level categorizations in Chinese and Israeli participants living in the respective countries. Categorization of faces by race, gender, and age was examined within subjects with participants who had only minimal experience with the other-race faces. As would be predicted by the previously documented other-race advantage effect, both Chinese and Israeli participants classified the race of the face more quickly and more accurately for other-race than for own-race faces. In contrast, the observers' race did not interact with the race of the rated face either for gender or for age categorization. The absence of these interactions suggests that the physiognomic characteristics that determine the gender and age of a face are universal, rather than race specific. Furthermore, these data suggest that determining the race of a face is not imposed as a first step in face processing, preempting the perception of other category-defining physiognomic characteristics.

    We sought to elucidate the associations of 13 items assessing negative perceptions about condom use with gender, age and race in a sample of clinic attendees. Patients from four clinics, in three US cities, were recruited (N = 928). Data were collected using audio-computer-assisted self-interviewing. The primary measure was a 13-item adapted version of the Condom Barriers Scale. Logistic regression and chi-square tests were employed to relate the 13 items to gender, age and race. Gender, race and age all had significant associations with negative perceptions of condoms and their use. A primary finding was a large number of significant differences between men and women, with negative perceptions more common among women than among men. For African Americans, especially women, negative perceptions were more common among older participants than among younger participants. In conclusion, important demographic differences regarding negative perceptions may inform the tailoring of intervention efforts that seek to rectify negative perceptions about condoms and thus promote condom use among individuals at risk for sexually transmitted infections (STIs) in the USA. On the other hand, our findings also suggest that the majority of STI clinic attendees may hold positive perceptions about condoms and their use; maintaining and building upon these positive perceptions via education, counselling, and access is also important.

    The CA-6000 Spine Motion Analyzer was used to measure the lumbar spine's range of motion (ROM). One hundred and four asymptomatic volunteers were examined to obtain normal values for flexion/extension, lateral bending, and axial rotation. A detailed error analysis was conducted to investigate the inter- and intraobserver reliability of the measurement equipment, the differences between passive and active examination, the effects of stretching exercises before examination, and the diurnal changes related to lumbar spine ROM. Subjects were divided into groups by age and gender. Values for each group were compared with respect to age and gender. The measurements were found to be consistent and repeatable. Stretching exercises were observed to increase ROM. Passive examination was recommended to achieve maximum ROM. ROM was observed to increase during the course of the day. A normative database was established showing significantly decreased motion as age increased, but no gender differences were discovered. The validity of the axial rotation values due to fixation difficulties is questioned. PMID:7749901

    In this study the effect of gender and age structure on municipal waste generation was investigated. The data from 10-year period, from 2001 to 2010 year, were taken into consideration. The following parameters of gender and age structure were analyzed: men and woman quantity, female to male ratio, number of working, pre-working and post-working age men/women, number of unemployed men/women. The results have showed a strong correlation of annual per capita waste generation rate with number of unemployed women (r=0.70) and female to male ratio (r=0.81). This indicates that waste generation rate is more depended on ratio of men and women that on quantitative size of each group. Using the regression analysis a model describing the dependence between female to male ratio, number of unemployed woman and waste quantity was determined. The model explains 70% of waste quantity variation. Obtained results can be used both to improve waste management and to a fuller understanding of gender behavior. PMID:25843355

    Individuals with psychosis are more likely than the general community to develop obesity and to die prematurely from heart disease. Interventions to improve cardiovascular outcomes are best targeted at the earliest indicators of risk, at the age they first emerge. We investigated which cardiometabolic risk indicators distinguished those with psychosis from the general population, by age by gender, and whether obesity explained the pattern of observed differences. Data was analyzed from an epidemiologically representative sample of 1,642 Australians with psychosis aged 18–64 years and a national comparator sample of 8,866 controls aged 25–64 years from the general population. Cubic b-splines were used to compare cross sectional age trends by gender for mean waist circumference, body mass index [BMI], blood pressure, fasting blood glucose, triglycerides, LDL, HDL, and total cholesterol in our psychosis and control samples. At age 25 individuals with psychosis had a significantly higher mean BMI, waist circumference, triglycerides, glucose [women only], and diastolic blood pressure and significantly lower HDL-cholesterol than controls. With the exception of triglycerides at age 60+ in men, and glucose in women at various ages, these differences were present at every age. Differences in BMI and waist circumference between samples, although dramatic, could not explain all differences in diastolic blood pressure, HDL-cholesterol or triglycerides but did explain differences in glucose. Psychosis has the hallmarks of insulin resistance by at least age 25. The entire syndrome, not just weight, should be a focus of intervention to reduce mortality from cardiovascular disease.

    OBJECTIVES. This study aimed to quantify the complex dynamics of beat-to-beat sinus rhythm heart rate fluctuations and to determine their differences as a function of gender and age. BACKGROUND. Recently, measures of heart rate variability and the nonlinear "complexity" of heart rate dynamics have been used as indicators of cardiovascular health. Because women have lower cardiovascular risk and greater longevity than men, we postulated that there are important gender-related differences in beat-to-beat heart rate dynamics. METHODS. We analyzed heart rate dynamics during 8-min segments of continuous electrocardiographic recording in healthy young (20 to 39 years old), middle-aged (40 to 64 years old) and elderly (65 to 90 years old) men (n = 40) and women (n = 27) while they performed spontaneous and metronomic (15 breaths/min) breathing. Relatively high (0.15 to 0.40 Hz) and low (0.01 to 0.15 Hz) frequency components of heart rate variability were computed using spectral analysis. The overall "complexity" of each heart rate time series was quantified by its approximate entropy, a measure of regularity derived from nonlinear dynamics ("chaos" theory). RESULTS. Mean heart rate did not differ between the age groups or genders. High frequency heart rate power and the high/low frequency power ratio decreased with age in both men and women (p < 0.05). The high/low frequency power ratio during spontaneous and metronomic breathing was greater in women than men (p < 0.05). Heart rate approximate entropy decreased with age and was higher in women than men (p < 0.05). CONCLUSIONS. High frequency heart rate spectral power (associated with parasympathetic activity) and the overall complexity of heart rate dynamics are higher in women than men. These complementary findings indicate the need to account for gender-as well as age-related differences in heart rate dynamics. Whether these gender differences are related to lower cardiovascular disease risk and greater longevity in

Green space was associated with better mental health, but only in specific age and gender groups, and only in a 3 km, not a 1 km buffer. The moderating effects of age and gender may be explained by whether or not people have the opportunity to make use of their green living environment. PMID:27187428

    Background Prolonged conflict in South Sudan exacerbated gender disparities and inequities. This study assessed differences in attitudes toward gender inequitable norms and practices by sex, age, and education to inform programming. Methods Applying community-based participatory research methodology, 680 adult respondents, selected by quota sampling, were interviewed in seven South Sudanese communities from 2009 to 2011. The verbally administered survey assessed attitudes using the Gender Equitable Men scale. Data were stratified by sex, age, and education. Results Of 680 respondents, 352 were female, 326 were male, and two did not report their sex. The majority of respondents agreed with gender inequitable household roles, but the majority disagreed with gender inequitable practices (i.e. early marriage, forced marriage, and inequitable education of girls). Respondents who reported no education were more likely than those who reported any education to agree with gender inequitable practices (all p<0.03) except for forced marriage (p=0.07), and few significant differences were observed when these responses were stratified by sex and age. Conclusion The study reveals agreement with gender inequitable norms in the household, but an overall disagreement with gender inequitable practices in sampled communities. The findings support that education of both women and men may promote gender equitable norms and practices. PMID:25026024

    A primary societal goal for aging is enabling older people to continue to live well as long as possible. The evidence base around aging well (“healthy,” “active,” and “successful” aging) has been constructed mainly from academic and professional conceptualizations of mortality, morbidity, functioning, and psychological well-being with some attention to lay views. Our study aims to inform action on health promotion to achieve aging well as conceptualized by qualitative research identifying what older Australians themselves value most: continuing to live as long as possible in the community with independence in daily living, and good self-rated health and psychological well-being. Multivariate survival analyses from the Melbourne longitudinal studies on healthy aging program found that important threats to aging well for the total sample over a 12-year period were chronological age, multi-morbidity, low perceived social support, low nutritional score, and being under-weight. For men, threats to aging well were low strain, perceived inadequacy of social activity, and being a current smoker. For women, urinary incontinence, low physical activity and being under-weight were threats to aging well. The findings indicate that healthy lifestyles can assist aging well, and suggest the value of taking gender into account in health promotion strategies. PMID:25072042

    Aim To examine age and gender differences in the prevalence and incidence of child sexual abuse, the level of acquaintance of the child and the perpetrator, and correlations between experiencing family violence and sexual abuse on a nationally representative sample of 11, 13, and 16 years old children. Method A probabilistic stratified cluster sample included 2.62% of the overall population of children aged 11 (n = 1223), 13 (n = 1188), and 16 (n = 1233) from 40 primary and 29 secondary schools. A modified version of ISPCAN Child Abuse Screening Tool – Children's Version was used. Five items referred to child sexual abuse (CSA) for all age groups. Results In Croatia, 10.8% of children experienced some form of sexual abuse (4.8% to 16.5%, depending on the age group) during childhood and 7.7% of children experienced it during the previous year (3.7% to 11.1%, depending on the age group). Gender comparison showed no difference in the prevalence of contact sexual abuse, whereas more girls than boys experienced non-contact sexual abuse. Correlations between sexual abuse and physical and psychological abuse in the family were small, but significant. Conclusion Comparisons with international studies show that Croatia is a country with a low prevalence of CSA. The fact that the majority of perpetrators of sexual abuse are male and female peers indicates the urgent need to address risks of sexual victimization in the health education of children.

    Ecological factors modulate animal immunocompetence and potentially shape the evolution of their immune systems. Not only environmental parameters impact on immunocompetence: Aging is one major cause of variability of immunocompetence between individuals, and sex-specific levels of immunocompetence have also been frequently described. Moreover, a growing core of data put in light that vertically transmitted symbionts can dramatically modulate the immunocompetence of their hosts. In this study, we addressed the influence of gender, age and the feminising endosymbiont Wolbachia (wVulC) on variations in haemocyte density, total PO activity and bacterial load in the haemolymph of the terrestrial isopod Armadillidium vulgare. This host-symbiont system is of particular interest to address this question since: (1) wVulC was previously shown as immunosuppressive in middle-aged females and (2) wVulC influences sex determination. We show that age, gender and Wolbachia modulate together immune parameters in A. vulgare. However, wVulC, which interacts with aging, appears to be the prominent factor interfering with both PO activity and haemocyte density. This interference with immune parameters is not the only aspect of wVulC virulence on its host, as reproduction and survival are also altered. PMID:20676599

    Aims: The study investigated gender differences in drinking patterns and the reasons behind them among men and women in the Russian city of Novosibirsk. Methods: A mixed method, combining quantitative and qualitative data, was conducted based on the Health, Alcohol and Psychosocial factors In Eastern Europe cohort study. The quantitative study included 4268 men and 5094 women aged 45–69 years; of those, 20 men and 24 women completed an in-depth interview. Results: The quantitative data revealed a large gap in drinking patterns in general between genders. Women drank less often and much smaller quantities than that of men. For example, 19% of men, vs. 1% of women, were classified as problem drinkers (two or more positive answers on the CAGE questionnaire). These differences were not explained by socioeconomic factors. Qualitative data have shown that gender roles and a traditional culture around women's and men's drinking were the main reasons for the reported drinking behaviour, whereby women were consistently expected to drink much less than men in terms of preference for strong beverages, drinking frequency and quantity of alcohol consumed. Conclusion: The study confirmed that large differences exist between Russian men's and women's drinking; these differences may be largely explained by gender roles. PMID:21075855

    Flow cytometry is now accepted as an ideal technology to reveal changes in immune cell composition and function. However, it is also an error-prone and variable technology, which makes it difficult to reproduce findings across laboratories. We have recently developed a strategy to standardize whole blood flow cytometry. The performance of our protocols was challenged here by profiling samples from healthy volunteers to reveal age- and gender-dependent differences and to establish a standardized reference cohort for use in clinical trials. Whole blood samples from two different cohorts were analyzed (first cohort: n = 52, second cohort: n = 46, both 20-84 years with equal gender distribution). The second cohort was run as a validation cohort by a different operator. The "ONE Study" panels were applied to analyze expression of >30 different surface markers to enumerate proportional and absolute numbers of >50 leucocyte subsets. Indeed, analysis of the first cohort revealed significant age-dependent changes in subsets e.g. increased activated and differentiated CD4(+) and CD8(+) T cell subsets, acquisition of a memory phenotype for Tregs as well as decreased MDC2 and Marginal Zone B cells. Males and females showed different dynamics in age-dependent T cell activation and differentiation, indicating faster immunosenescence in males. Importantly, although both cohorts consisted of a small sample size, our standardized approach enabled validation of age-dependent changes with the second cohort. Thus, we have proven the utility of our strategy and generated reproducible reference ranges accounting for age- and gender-dependent differences, which are crucial for a better patient monitoring and individualized therapy. © 2016 International Society for Advancement of Cytometry.

    The present study aimed to investigate the moderating roles of gender and age on emotional abuse within intimate relationships. This study included 250 participants with an average age of 27 years. Participants completed the Emotional Abuse Questionnaire (EAQ; Jacobson and Gottman, 1998), whose four subscales are isolation, degradation, sexual abuse, and property damage. Multigroup analysis with two groups, female (n = 141) and male (n = 109), was used to test the moderation effect. Younger men reported experiencing higher levels of emotional abuse, which declined with age. Older females reported experiencing less emotional abuse than older males. Overall, emotional abuse was more common in younger participants. Younger women experienced higher rates of isolation, and women’s overall experience of property damage was higher than that of men and increased with age. Results are interpreted through the Social Exchange and Conflict frameworks. PMID:24364124

    This article presents estimates of personal health care spending by age and gender in selected years during the period 2002-10 and an analysis of the variation in spending among children, working-age adults, and the elderly. Our research found that in this period, aggregate spending on children's health care increased at the slowest rate. However, per capita spending for children grew more rapidly than that for working-age adults and the elderly. Per capita spending for the elderly remained about five times higher than spending for children. Overall, females spent more per capita than males, but the gap had decreased by 2010. The implementation of Medicare Part D, the effects of the recent recession, and the aging of the baby boomers affected the spending trends and distributions during the period of this study.

    OBJECTIVE—The purpose of this study was to examine age of diabetes diagnosis in youth who have a parent with diabetes by diabetes type and whether the parent's diabetes was diagnosed before or after the youth's birth. RESEARCH DESIGN AND METHODS—The cohort comprised SEARCH for Diabetes in Youth Study participants (diabetes diagnosis 2001–2005) with a diabetic parent. SEARCH is a multicenter survey of youth with diabetes diagnosed before age 20 years. RESULTS—Youth with type 2 diabetes were more likely to have a parent with either type 1 or type 2 diabetes (mother 39.3%; father 21.2%) than youth with type 1 diabetes (5.3 and 6.7%, respectively, P < 0.001 for each). Type 2 diabetes was diagnosed 1.68 years earlier among those exposed to diabetes in utero (n = 174) than among those whose mothers’ diabetes was diagnosed later (P = 0.018, controlled for maternal diagnosis age, paternal diabetes, sex, and race/ethnicity). Age at diagnosis of type 1 diabetes for 269 youth with and without in utero exposure did not differ significantly (difference 0.96 year, P = 0.403 after adjustment). Controlled for the father's age of diagnosis, father's diabetes before the child's birth was not associated with age at diagnosis (P = 0.078 for type 1 diabetes; P = 0.140 for type 2 diabetes). CONCLUSIONS—Type 2 diabetes was diagnosed at younger ages among those exposed to hyperglycemia in utero. Among youth with type 1 diabetes, the effect of the intrauterine exposure was not significant when controlled for mother's age of diagnosis. This study helps explain why other studies have found higher age-specific rates of type 2 diabetes among offspring of women with diabetes. PMID:18694977

    Gender and age have been found to affect adults’ audio-visual (AV) speech perception. However, research on adult aging focuses on adults over 60 years, who have an increasing likelihood for cognitive and sensory decline, which may confound positive effects of age-related AV-experience and its interaction with gender. Observed age and gender differences in AV speech perception may also depend on measurement sensitivity and AV task difficulty. Consequently both AV benefit and visual influence were used to measure visual contribution for gender-balanced groups of young (20–30 years) and middle-aged adults (50–60 years) with task difficulty varied using AV syllables from different talkers in alternative auditory backgrounds. Females had better speech-reading performance than males. Whereas no gender differences in AV benefit or visual influence were observed for young adults, visually influenced responses were significantly greater for middle-aged females than middle-aged males. That speech-reading performance did not influence AV benefit may be explained by visual speech extraction and AV integration constituting independent abilities. Contrastingly, the gender difference in visually influenced responses in middle adulthood may reflect an experience-related shift in females’ general AV perceptual strategy. Although young females’ speech-reading proficiency may not readily contribute to greater visual influence, between young and middle-adulthood recurrent confirmation of the contribution of visual cues induced by speech-reading proficiency may gradually shift females AV perceptual strategy toward more visually dominated responses.

    This paper examines gender differentials in survival amongst older people (50+ years) in the Nairobi slums and to the best of our knowledge is the first study of its kind in an urban African setting. The results provide evidence contrary to the expected paradox of poorer self-rated health yet better survival amongst older women. Older women in the Nairobi slums have poorer self-rated health and poorer circumstances across other factors, including disability and socio-economic status. Further, older women in the slums do not have better survival. The conventional female advantage in mortality only becomes apparent after accounting for the cumulative influence of individual characteristics, social networks, health and socio-economic status, suggesting the female advantage in unadjusted old-age mortality does not apply to contexts where women experience significant disadvantage across multiple life domains. This highlights the urgent need to redress the support, status and opportunities available for women across the life course in contexts such as the Nairobi slums. In addition, a greater number of factors differentiate mortality risk amongst men than amongst women, suggesting inequality amongst slum dwelling older men and highlighting the need for gender sensitive interventions which account for the particular needs of both genders in old age.

    The objective of this study was to determine potential post-pubertal gender-specific differences in the contractility of papillary muscles, the electrophysiological properties and Ca2+ transients of freshly dissociated ventricular myocytes from the rat heart. The contractions of rat papillary muscles from 2- to 14-month-old male and female rats were studied under isometric and isotonic conditions (29 °C). While the hearts of young (2–4 months) male and female rats displayed a similar contractile profile, papillary muscles of female rats aged 6 months and older exhibited smaller isometric and isotonic contractions, smaller maximal rates of tension and shortening development and decline (±DT/dt and ±DL/dt) velocities during both the onset and relaxation phases, and shorter contractions than age-matched males. To explore the possible cellular basis accounting for these differences, action potentials and macroscopic currents were recorded from freshly dissociated myocytes using the whole-cell patch clamp technique (35 °C). Action potentials from male and female myocytes of 3- and 9-month-old rats did not vary as a function of age or gender. Consistent with these results, the magnitude (expressed in pA pF−1), voltage-dependence and kinetics of the inward rectifier (IK1), transient outward (Ito) and sustained (IK) K+ currents displayed little, if any dependence on age or gender. L-type Ca2+ current (ICa(L)) measured in caesium-loaded myocytes (35 °C) from male and female rats of 3, 6 and 9 months of age exhibited similar characteristics. In contrast, while Ca2+ transients measured with indo-1 were similar between 3-month-old male and female rat myocytes, Ca2+ transients of 10-month-old female myocytes were significantly reduced and showed a diminished rate of relaxation in comparison with those recorded in male rats of similar age. These results suggest that important gender-related changes in excitation-contraction coupling occur following puberty, probably due

    Total sleep duration has been decreasing among children in the last decades. Short sleep duration (SSD) has been associated with deleterious health consequences, such as excess weight/obesity. Risk factors for SSD have already been studied among school-aged children and adolescents, but inconsistent results have been reported regarding possible gender differences. Studies reporting such relationships are scarce in preschoolers, despite the importance of this period for adopting healthy behaviour. We aimed to investigate factors associated with SSD in 3-year-old boys (n = 546) and girls (n = 482) in a French Mother-Child Cohort (EDEN Study). Children were born between 2003 and 2006 in two French university hospitals. Clinical examinations and parent self-reported questionnaires allowed us to collect sociodemographic (e.g. income, education, family situation, child-minding system), maternal [e.g. body mass index (BMI), parity, depression, breastfeeding duration] and child's characteristics (e.g. gender, birth weight, term, physical activity and TV viewing duration, food consumption, usual sleep time). Sleep duration/24-h period was calculated and SSD was defined as <12 h. Analyses were performed using logistic regression. The mean sleep duration was 12 h 35 ± 56 min, with 91% of the children napping. Patterns of risk factors associated with SSD differed according to gender. In addition to parental presence when falling asleep, short sleep duration was associated strongly positively with high BMI Z-score and TV viewing duration among boys and with familial home child-minding and lower scores on the 'fruits and vegetables' dietary pattern among girls. These results suggest either a patterning of parental behaviours that differs according to gender, or a gender-specific sleep physiology, or both. PMID:26041449

    One of the clinical hallmarks of hereditary cancer susceptibility disorders is a younger-than-usual age at diagnosis. Familial aggregation of testicular germ cell tumor (TGCT) has been reported, but data on whether familial TGCT cases are diagnosed at an earlier age are inconclusive. Here we compared the age at diagnosis of familial TGCT cases with that of population cases in several countries. Familial TGCT is defined as affected individuals from families with >or=2 cases of TGCT. Age at diagnosis of familial cases from the United States, Canada, United Kingdom, Australia and New Zealand, Norway, and Hungary was compared to cases identified in population-based cancer registries from the respective country, using the generalized estimation equation method. Age at diagnosis was statistically significantly younger for familial TGCT cases from North America (P = 0.024), the United Kingdom (P < 0.0001), and Australia and New Zealand (P = 0.0033) compared with population cases. When stratified by histology, the difference in age at diagnosis distribution between familial and population cases was observed for seminoma cases from North America (P = 0.002) and the United Kingdom (P < 0.0001) and non-seminoma cases from the United Kingdom (P = 0.029) and Australia and New Zealand (P = 0.0023). In summary, we found that the age at diagnosis for familial TGCT cases is, on the average, 2-3 years younger than that for the population cases in North America, United Kingdom, and Australia and New Zealand. The younger age at diagnosis might be suggestive of a genetic basis for familial TGCT. PMID:19609727

    Analysis of literature shows that very little data are available on gender differences and age-specific drug use in the treatment of chronic heart failure (CHF). In this work, the character of drug therapy was studied as dependent on the age and sex of patients with CHF under in-hospital observation conditions. Among hospitalized patients with CHF, an important role is played by modern drug therapy. Gender differences were found in respect of therapy with ACE inhibitors, which was used in men more frequently than in women (89 and 78%, respectively, p <0.001). Aldosterone antagonists were used in the treatment of women much less frequently than in men (32.9 and 42%, respectively, p < 0.001). Loop diuretics are more frequently prescribed to men (48 and 40%, respectively, p < 0.001) and thiazide diuretics, to women (38.9 and 27%, respectively, p < 0.001). In older age groups, CHF treatment both in men (p < 0.05) and in women (p < 0.001) is characterized by decreased use of beta-adrenoblockers and increased use of aldosterone antagonists (p < 0.05). In women, older age groups meet increased prescription frequency of ACE inhibitors/ARBs (from 79.1 to 95.3%p < 0.01) and aldosterone antagonists (from 29.3 to 38.2% p < 0.001). PMID:27416677

    Basic data on the resting energy expenditure (REE) of healthy populations are currently rare, especially for developing countries. The aims of the present study were to describe gender- and age-specific REE distributions and to evaluate the relationships among glycolipid metabolism, eating behaviors, and REE in healthy Chinese adults. This cross-sectional survey included 540 subjects (343 women and 197 men, 20-79 years old). REE was measured by indirect calorimetry and expressed as kcal/day/kg total body weight. The data were presented as the means and percentiles for REE and the REE to fat-free mass (FFM) ratio; differences were described by gender and age. Partial correlation analysis was used to analyze the correlations between REE, tertiles of REE/FFM, and glycolipid metabolism and eating behaviors. In this study, we confirmed a decline in REE with age in women (p = 0.000) and men (p = 0.000), and we found that men have a higher REE (p = 0.000) and lower REE/FFM (p = 0.021) than women. Furthermore, we observed no associations among glycolipid metabolism, eating behaviors, and REE in healthy Chinese adults. In conclusion, the results presented here may be useful to clinicians and nutritionists for comparing healthy and ill subjects and identifying changes in REE that are related to aging, malnutrition, and chronic diseases.

    No previous study of Alzheimer's disease has, to our knowledge, assessed the effect of both age at dementia onset and gender on cerebral glucose metabolic patterns. To this end, we used positron emission tomography (fludeoxyglucose F 18 method) to study 24 patients with clinical diagnoses of probable Alzheimer's disease. Comparisons of the 13 patients with early-onset dementia (less than 65 years of age) with the 11 patients with late-onset dementia (greater than 65 years of age) revealed significantly lower left parietal metabolic ratios (left posterior parietal region divided by the hemispheric average) in the early-onset group. The metabolic ratio of posterior parietal cortex divided by the relatively disease-stable average of caudate and thalamus also separated patients with early-onset dementia from those with late-onset dementia, but not men from women. Further comparisons between sexes showed that, in all brain regions studied, the 9 postmenopausal women had higher nonweighted mean metabolic rates than the 15 men from the same age group, with hemispheric sex differences of 9% on the right and 7% on the left. These results demonstrate decreased parietal ratios in early-onset dementia of Alzheimer's disease, independent of a gender effect.

    Using data from the National Survey of Homeless Assistance Providers and Clients (NSHAPC) and an application of Felson's Routine Activities Theory, this paper examines gender and age differences in victimization experiences of a sample of more than 4,200 homeless and near-homeless people, mostly adults. Results suggest that there are no differences in victimization experience by homelessness status and that the negative relationship between age and victimization rates found in the general population is also found in the homeless population. However, the relationship is relatively weak and erratic, suggesting that homeless older adults who are at least 50 years old are at increased risk of becoming victims, a finding consistent with Routine Activities Theory. In addition, similar to research with other populations, younger homeless males are statistically more likely to report being victims of theft and physical assault while females of all ages are more likely to report being victims of sexual assault. However, for older homeless adults, the gender difference in likelihood of victimization disappears. Perhaps because older homeless women are labeled as easy targets, they were equally as likely as men to be victims of physical assault and theft in old age. This is also consistent with Routine Activities Theory. PMID:16611616

    This study had the objective to collect the self and the others perception of elderly men and women about the social roles of gender in the extent of the old age. The empirical material was captured by a workshop of reflection, involving six men and ten women who accept to be on the research. The data was examined by the technical of speech analysis, being based on the gender respect. The discoveries demonstrate that the elderly demand, as for themselves as for the other (of the opposite sex), the exercise of social roles certain by verified standards in the extend of the sexist society, established starting from the made relationships between the public and the private domains, being the masculine associated to the public world, and the feminine, to the house domain.

    Gender-related differences in the association between polymorphism of xenobiotic-metabolising enzymes or non-genetic biomarkers and susceptibility to oxidative stress was assessed in healthy middle-aged Serbian adults, by urinary 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG/creatinine) and total antioxidant status in serum (TAOS). Females were more susceptible to oxidative stress. In both genders, positive predictor of the antioxidative protection was serum triglyceride, while BMI <25 kg/m(2) was associated with oxidative stress. Susceptibility to oxidative stress in males was associated with GSTT1*null allele and increased serum iron, but in females, it was decreased serum bilirubin. Early identification of the risk factors could be important in the prevention of oxidative stress-related diseases. PMID:26754535

    Objective To examine childhood aggression at age 5 in a multiple risk model that includes cocaine exposure, environmental risk, and gender as predictors. Methods Aggression was assessed in 206 children by using multiple methods including teacher report, parent report, child’s response to hypothetical provocations, and child’s observed behavior. Also examined was a composite score that reflected high aggression across contexts. Results Multiple regression analyses indicated that a significant amount of variance in each of the aggression measures and the composite was explained by the predictors. The variables that were independently related differed depending on the outcome. Cocaine exposure, gender, and environmental risk were all related to the composite aggression score. Conclusions Cocaine exposure, being male, and a high-risk environment were all predictive of aggressive behavior at 5 years. It is this group of exposed boys at high environmental risk that is most likely to show continued aggression over time. PMID:15827351

    Background It is generally accepted that smoking starts in adolescence and earlier initiation is associated with more negative health outcomes. Some research suggests that women initiate smoking at later ages and have more negative health outcomes than men. The purpose of this study was to examine gender differences in age of initiation and its association with health. Methods The sample included men (n=8,506) and women (n=8,479) with a history of smoking from the 2001-2002 National Epidemiological Survey of Alcohol Related Conditions. Logistic regression was used to examine gender differences in the effect of late smoking initiation on physical and mental health status after adjusting for covariates. Results At mostly all ages after 16, women exceeded men in rates of smoking initiation (59.8% vs. 50.3%, p<.001). Among late initiators (≥16), women were more likely than men to have hypertension (OR:1.24,CI:1.09-1.41), heart disease (OR:1.20,CI:1.00-1.45), major depressive disorder (OR:2.54,CI:2.22-2.92) and generalized anxiety disorder (OR:2.34,CI:1.84-2.99). Among early initiators (<16), women were more likely than men to have major depressive disorder (OR:2.42,CI:2.11-2.77) and generalized anxiety disorder (OR:2.01,CI:1.59-2.54) but there were no gender differences in the likelihood of having hypertension (OR:1.04,CI:0.89-1.22) and heart disease (OR:1.11,CI:0.90-1.36). Conclusions In late adolescence and adulthood, women exceed men in smoking initiation. Late initiation was associated with more significant physical health risks for women than men. Our findings raise questions about generally accepted notions on the age at which smoking initiation occurs and its association with health.

    Deficits in executive functions occur in up to 93% of patients with Parkinson's disease (PD). Apathy, a reduction of motivation and goal-directed behavior is an important part of the syndrome; affecting both the patients as well as their social environment. Executive functions can be subdivided into three different processes: initiation, shifting and inhibition. We examined the hypotheses, (1) that apathy in patients with Parkinson's disease is only related to initiation and not to shifting and inhibition, and (2) that depression and severity of motor signs correlate with apathy. Fifty-one non-demented patients (19 = female) with PD were evaluated for apathy, depression and executive functions. Executive function variables were summarized with an index variable according to the defined executive processes. Linear regression with stepwise elimination procedure was used to select significant predictors. The significant model (R2 = 0.41; p < 0.01) revealed influences of initiation (b = −0.79; p < 0.01), gender (b = −7.75; p < 0.01), age (b = −0.07; p < 0.05) and an age by gender interaction (b = 0.12; p < 0.01) on apathy in Parkinson's disease. Motor signs, depression and level of education did not influence the relation. These results support an association of apathy and deficits of executive function in PD. Initiation strongly correlates with apathy, whereas depression does not. We conclude, that initiation dysfunction in a patient with Parkinson's disease heralds apathy. Apathy and depression can be dissociated. Additionally, apathy is influenced by age and gender: older age correlates with apathy in men, whereas in women it seems to protect against it.

    Blood is a commonly used biofluid for biomarker discovery. Although blood lipid metabolites are considered to be potential biomarker candidates, their fundamental properties are not well characterized. We aimed to (1) investigate the matrix type (serum vs. plasma) that may be preferable for lipid biomarker exploration, (2) elucidate age- and gender-associated differences in lipid metabolite levels, and (3) examine the stability of lipid metabolites in matrix samples subjected to repeated freeze-thaw cycles. Using liquid chromatography-mass spectrometry, we performed lipidomic analyses for fasting plasma and serum samples for four groups (15 subjects/group) of young and elderly (25–34 and 55–64 years old, respectively) males and females and for an additional aliquot of samples from young males, which were subjected to repeated freeze-thaw cycles. Lysophosphatidylcholine and diacylglycerol levels were higher in serum than in plasma samples, suggesting that the clotting process influences serum lipid metabolite levels. Gender-associated differences highlighted that the levels of many sphingomyelin species were significantly higher in females than in males, irrespective of age and matrix (plasma and serum). Age-associated differences were more prominent in females than in males, and in both matrices, levels of many triacylglycerols were significantly higher in elderly females than in young females. Plasma and serum levels of most lipid metabolites were reduced by freeze-thawing. Our results indicate that plasma is an optimal matrix for exploring lipid biomarkers because it represents the original properties of an individual’s blood sample. In addition, the levels of some blood lipid species of healthy adults showed gender- and age-associated differences; thus, this should be considered during biomarker exploration and its application in diagnostics.

    This study examined the influence of age, gender and race on nitric oxide (NO) release over acupuncture points, meridian without acupoint, and non-meridian regions of the Pericardium (PC) and Bladder (BL) meridian as well as aging on LU meridian in 61 healthy subjects. Biocapture tubes were attached to the skin surface, and total nitrite and nitrate was biocaptured and quantified using chemiluminescence. In elder ages compared to adults, NO levels over the ventral forearm were significantly decreased over LU on radial regions but not altered over PC on medial regions. Conversely, NO content was elevated over BL regions only in overweight/obesity of elder ages. NO levels over PC regions were marginally elevated in overweight/obese males compared to females but did not alter between races. These results suggest a selective reduction of NO release over LU meridian with aging, which is consistent with a progressive decline in lung function and increase in chronic respiratory disease in elder ages. Increased NO levels along the BL meridian in older obese subjects may reflect a modified NO level along somatic-bladder pathway for counteracting bladder dysfunctions with aging. Both of them support somatic-organ connections in the meridian system associated with potential pathophysiological changes with aging. PMID:26621821

    2015-10-01

    Neurofibromatosis type 1 (NF1), is a haploinsufficient and multisystemic disease, caused by inherited or sporadic mutations in the NF1 gene. Its incidence is one in 2,500 to 3,000 individuals, it has an autosomal dominant pattern of inheritance, high clinical variability, complete penetrance and age-dependent complications. Neurofibromin is the product of the NF1 gene and is believed to act as a tumor suppressor since the loss of its function has been associated with benign and malignant tumors in neural crest-derived tissues. Only two correlations between clinical phenotype and mutant alleles in the NF1 gene have been observed. The established criteria for disease diagnosis are very efficient in adults and children older than 3 years of age, but not for children under this age. Mutational analysis is therefore recommended to confirm the disease in young children with a negative family history. A pathogenic mutation in the NF1 should be added to the list of diagnostic criteria. Mutational analysis is also recommended for differential diagnosis and for prenatal or pre-implantation genetic diagnosis, taking into consideration the family history and the type of method to be applied. Molecular studies of this disease using different complimentary molecular techniques and bioinformatics tools have characterized NF1 gene mutations at both the DNA and mRNA levels, increasing the mutational spectrum. Consequently, about 1,289 defects have been reported to date, mainly nonsense/missense mutations, deletions and splice site defects. PMID:26633276

    Objectives: We assessed the association of smoking at diagnosis of inflammatory bowel disease (IBD) on the need for an intestinal resection. Methods: The Health Improvement Network was used to identify an inception cohort of Crohn's disease (n=1519) and ulcerative colitis (n=3600) patients from 1999–2009. Poisson regression explored temporal trends for the proportion of newly diagnosed IBD patients who never smoked before their diagnosis and the risk of surgery within 3 years of diagnosis. Cox proportional hazard models assessed the association between smoking and surgery, and effect modification was explored for age at diagnosis. Results: The rate of never smokers increased by 3% per year for newly diagnosed Crohn's disease patients (incidence rate ratio (IRR) 1.03; 95% confidence interval (CI): 1.02–1.05), but not for ulcerative colitis. The rate of surgery decreased among Crohn's disease patients aged 17–40 years (IRR 0.96; 95% CI: 0.93–0.98), but not for ulcerative colitis. Smoking at diagnosis increased the risk of surgery for Crohn's disease patients diagnosed after the age of 40 (hazard ratio (HR) 2.99; 95% CI: 1.52–5.92), but not for those diagnosed before age 40. Ulcerative colitis patients diagnosed between the ages of 17 and 40 years and who quit smoking before their diagnosis were more likely to undergo a colectomy (ex-smoker vs. never smoker: HR 1.66; 95% CI: 1.04–2.66). The age-specific findings were consistent across sensitivity analyses for Crohn's disease, but not ulcerative colitis. Conclusions: In this study, the association of smoking and surgical resection was dependent on the age at diagnosis of IBD. PMID:27101004

    Background and aim To update our 1996 review on the incidence of subarachnoid haemorrhage (SAH) and assess the relation of incidence with region, age, gender and time period. Methods We searched for studies on the incidence of SAH published until October 2005. The overall incidences with corresponding 95% confidence intervals were calculated. We determined the relationship between the incidence of SAH and determinants by means of univariate Poisson regression. Results We included 51 studies (33 new), describing 58 study populations in 21 countries, observing 45 821 896 person‐years. Incidences per 100 000 person‐years were 22.7 (95% CI 21.9 to 23.5) in Japan, 19.7 (18.1 to 21.3) in Finland, 4.2 (3.1 to 5.7) in South and Central America, and 9.1 (8.8 to 9.5) in the other regions. With age category 45–55 years as the reference, incidence ratios increased from 0.10 (0.08 to 0.14) for age groups younger than 25 years to 1.61 (1.24 to 2.07) for age groups older than 85 years. The incidence in women was 1.24 (1.09 to 1.42) times higher than in men; this gender difference started at age 55 years and increased thereafter. Between 1950 and 2005, the incidence decreased by 0.6% (1.3% decrease to 0.1% increase) per year. Conclusions The overall incidence of SAH is approximately 9 per 100 000 person‐years. Rates are higher in Japan and Finland and increase with age. The preponderance of women starts only in the sixth decade. The decline in incidence of SAH over the past 45 years is relatively moderate compared with that for stroke in general. PMID:17470467

    The hospital is a thermal environment where comfort must be calibrated by taking into account two different groups of people, that is, patients and medical staff. The study involves 30 patients and 19 medical staff with a view to verifying if Predicted Mean Vote (PMV) index can accurately predict thermal sensations of both groups also taking into account any potential effects of age and gender. The methodology adopted is based on the comparison between PMV values (calculated according to ISO 7730 after having collected environmental data and estimated personal parameters) and perceptual judgments (Actual Mean Vote, AMV), expressed by the subjects interviewed. Different statistical analyses show that PMV model finds his best correlation with AMV values in a sample of male medical staff under 65 years of age. It has been observed that gender and age are factors that must be taken into account in the assessment of thermal comfort in the hospital due to very weak correlation between AMV and PMV values.

  6. Population profiling in China by gender and age: implication for HIV incidences

    PubMed Central

    2009-01-01

    Background With the world's largest population, HIV spread in China has been closely watched and widely studied by its government and the international community. One important factor that might contribute to the epidemic is China's numerous surplus of men, due to its imbalanced sex ratio in newborns. However, the sex ratio in the human population is often assumed to be 1:1 in most studies of sexually transmitted diseases (STDs). Here, a mathematical model is proposed to estimate the population size in each gender and within different stages of reproduction and sexual activities. This population profiling by age and gender will assist in more precise prediction of HIV incidences. Method The total population is divided into 6 subgroups by gender and age. A deterministic compartmental model is developed to describe birth, death, age and the interactions among different subgroups, with a focus on the preference for newborn boys and its impact for the sex ratios. Data from 2003 to 2007 is used to estimate model parameters, and simulations predict short-term and long-term population profiles. Results The population of China will go to a descending track around 2030. Despite the possible underestimated number of newborns in the last couple of years, model-based simulations show that there will be about 28 million male individuals in 2055 without female partners during their sexually active stages. Conclusion The birth rate in China must be increased to keep the population viable. But increasing the birth rate without balancing the sex ratio in newborns is problematic, as this will generate a large number of surplus males. Besides other social, economic and psychological issues, the impact of this surplus of males on STD incidences, including HIV infections, must be dealt with as early as possible. PMID:19922693

    The purpose of this cross-sectional study was to explore associations between academic achievement, employment, gender, and age in relation to students' sense of school membership and perception of adults in school. The sample consisted of 102 secondary, alternative school students. Results indicated that students with a more positive perception of school personnel also reported a greater sense of school membership. Male students and older students had a more negative perception of administrators relative to female and younger students. In addition, students who worked tended to report higher grades than students who did not. Study implications are discussed. PMID:19086669

    Background Research is needed to determine the prevalence and variables associated with the diagnosis of flatfoot, and to evaluate the validity of three footprint analysis methods for diagnosing flatfoot, using clinical diagnosis as a benchmark. Methods We conducted a cross-sectional study of a population-based random sample ≥40 years old (n = 1002) in A Coruña, Spain. Anthropometric variables, Charlson’s comorbidity score, and podiatric examination (including measurement of Clarke’s angle, the Chippaux-Smirak index, and the Staheli index) were used for comparison with a clinical diagnosis method using a podoscope. Multivariate regression was performed. Informed patient consent and ethical review approval were obtained. Results Prevalence of flatfoot in the left and right footprint, measured using the podoscope, was 19.0% and 18.9%, respectively. Variables independently associated with flatfoot diagnosis were age (OR 1.07), female gender (OR 3.55) and BMI (OR 1.39). The area under the receiver operating characteristic curve (AUC) showed that Clarke’s angle is highly accurate in predicting flatfoot (AUC 0.94), followed by the Chippaux-Smirak (AUC 0.83) and Staheli (AUC 0.80) indices. Sensitivity values were 89.8% for Clarke’s angle, 94.2% for the Chippaux-Smirak index, and 81.8% for the Staheli index, with respective positive likelihood ratios or 9.7, 2.1, and 2.0. Conclusions Age, gender, and BMI were associated with a flatfoot diagnosis. The indices studied are suitable for diagnosing flatfoot in adults, especially Clarke’s angle, which is highly accurate for flatfoot diagnosis in this population. PMID:25382154

    Aims: To test whether (1) physically demanding work is less frequent for older than younger employees, and whether (2) the association of physically demanding work with decline of physical functioning is stronger for older employees than their younger counterparts. The gender differences in these associations were examined. Methods: Subjects of the study were 40–60 year old employees of the City of Helsinki. Data (n = 5802) were collected with mail questionnaires in 2000 and 2001. Functioning was measured with the Role Limitations due to Physical Health Problems scale of the SF36 health questionnaire. Logistic regression models were used to analyse the data. Results: There was a linear trend of less physically demanding work in older than in younger age groups. This trend was more marked for men than women. Age and physically demanding work were associated with poor functioning. In women the association of physically demanding work with poor functioning tended to be stronger for older than for younger age groups, while the opposite was observed in men. Conclusions: Results suggest that physically demanding work causes more ailments in women of high age than men. It is possible that less men than women are still employed in physically demanding occupations at high age, even though direct evidence of exit from physically demanding work cannot be obtained from cross-sectional data. In these data the physically demanding occupations for men and women were largely different. High physical workload among women working in social and health care is likely to contribute to the gender differences. PMID:15657190

    As the "baby boomers" age, the percentage of the population over sixty-five years of age is increasing rapidly. Chronic disease management is an important component in the care of the elderly. The effects of aging on different organ systems are also pertinent; such as the weakening homeostatic response to injury in the older individuals. Mucosal surfaces have the largest combined surface area in the body and are the site of important host microbe interactions, especially in the gut which is prone to injury, both from local and systemic insult. This susceptibility has been known to increase with age. Therefore it is important to understand the interplay between aging, injury and recovery at the mucosal surface. Sex hormones play an important role in the maintenance of the mucosal barrier function as well as the mucosa associated immune function in both genders. Menopause in women is a defined time period in which major hormonal changes occur such as a decline in systemic estradiol levels. The differential levels of sex hormones contribute to the sexual dimorphism seen in response to injury at the mucosal surface, prior to and following menopause. Thus the effect of sex hormone and aging on mucosal mechanisms in response to injury is an important area of investigation. PMID:24729941

    As males and females with autism spectrum disorder (ASD) experience different symptomology, their needs for vocational rehabilitation (VR) are unique as they transition into adulthood. This study examined the effects of gender differences in VR service predictors on employment outcomes for transition-aged individuals with ASD. A total of 1696 individuals (857 males and 839 females) were analyzed from a sample of RSA-911 data of FY 2011. Hierarchical logistic regression analyses were conducted. Results revealed both gender-independent VR service predictors (with job placement and on-the-job supports more beneficial for both genders) and gender-specific predictors of employment (with counseling and guidance, job search assistance, and other services more beneficial for the male group). This study provides support for individualized gender-specific VR services for people with ASD. PMID:26060047

    Background: Little is known about the variation in exposure to toxic metals by age and gender and other potential modifying factors. We evaluated age and gender differences by measurements of metal/element concentrations in urine in a rural population in Matlab, Bangladesh, in three age groups: 8-12 (N=238), 14-15 (N=107) and 30-88 (N=710) years of age, living in an area with no point sources of metal exposure but where elevated water arsenic concentrations are prevalent. Results: We found marked differences in urine concentrations of metals and trace elements by gender, age, tobacco use, socioeconomic and nutritional status. Besides a clearly elevated urinary arsenic concentration in all age groups (medians 63-85 {mu}g As/L), and despite the low degree of contamination from industries and traffic, the urine concentrations of toxic metals such as cadmium and lead were clearly elevated, especially in children (median 0.31 {mu}g Cd/L and 2.9 {mu}g Pb/L, respectively). In general, women had higher urinary concentrations of toxic metals, especially Cd (median 0.81 {mu}g/L) compared to men (0.66 {mu}g/L) and U (median 10 ng/L in women, compared to 6.4 ng/L in men), while men had higher urinary concentrations of the basic and essential elements Ca (69 mg/L in men, 30-50 years, compared to 52 mg/L in women), Mg (58 mg/L in men compared to 50 mg/L in women), Zn (182 {mu}g/L in men compared to 117 {mu}g/L in women) and Se (9.9 {mu}g/L in men compared to 8.7 {mu}g/L in women). Manganese was consistently higher in females than in males in all age groups, suggesting a biological difference between females and males in Mn metabolism. Increasing socioeconomic status decreased the toxic metal exposure significantly in children and especially in men. Poor iron status was detected in 17% of children, adolescents and women, but only in 6% of men. Also zinc deficiency was more prevalent in females than in males. Conclusions: Women and children seemed to be more at risk for toxic

    Chemical compounds on the cuticle are a rich source of information used during interactions among social insects. Despite the multitude of studies on these substances and their function in ants, wasps, and honeybees, little is known about this subject in stingless bees (Hymenoptera: Apidae, Meliponini). We studied the chemical composition of the cuticle of the stingless bee, Frieseomelitta varia, by gas chromatography-mass spectrometry (GC-MS), to investigate potential chemical variation among castes, gender, age, and reproductive status. We found differences in the cuticular hydrocarbon composition among workers, males, and queens, recording both qualitative and quantitative differences among individuals of different ages and gender. The cuticle of physogastric queens presented a chemical profile that was distinct from all other groups in the analysis, with high relative abundances of alkenes and alkadienes with 27, 29, and 31 carbon atoms. We discuss the possibility that these compounds signal a queen's presence to the colony, thereby initiating all vital worker-queen interactions. PMID:19813058

    The aim of the present paper is to show how the variation of the EEG frontal cortical asymmetry is related to the general appreciation perceived during the observation of TV advertisements, in particular considering the influence of the gender and age on it. In particular, we investigated the influence of the gender on the perception of a car advertisement (Experiment 1) and the influence of the factor age on a chewing gum commercial (Experiment 2). Experiment 1 results showed statistically significant higher approach values for the men group throughout the commercial. Results from Experiment 2 showed significant lower values by older adults for the spot, containing scenes not very enjoyed by them. In both studies, there was no statistical significant difference in the scene relative to the product offering between the experimental populations, suggesting the absence in our study of a bias towards the specific product in the evaluated populations. These evidences state the importance of the creativity in advertising, in order to attract the target population. PMID:27313602

    In developed countries, falls in older people represent a rising problem. As effective prevention should start before the risk becomes evident, an early predictor is needed. Single stance instability would appear as a major risk factor. Aims of the study were to describe single stance stability, its sensory components, and their correlation with age and gender. A random sample of 597 older adults (319 men, 278 women) living at home, aged 65-84, was studied. Stability tests were performed with an electronic postural station. The single stance test showed the impairment of single stance stability in older individuals (75-84 yrs). The significant decline of stability in the older subjects may be explained by the impairment of proprioceptive control together with the decrease in compensatory visual stabilization and emergency responses. Younger subjects (65-74 yrs) exhibited better, but still inadequate, proprioceptive control with compensatory visual stabilization. Gender differences appeared in older subjects: women were significantly less stable than men. The measurement of the sensory components of single stance stability could aid in the early detection of a decay in antigravity movements many years before the risk of falling becomes evident. Adequate proprioceptive control could mitigate the effects of all other risks of falling. PMID:23984068

    Keratinocytes account for 95% of all cells of the epidermis, the stratified squamous epithelium forming the outer layer of the skin, in which a significant number of skin diseases takes root. Immortalized keratinocyte cell lines are often used as research model systems providing standardized, reproducible, and homogenous biological material. Apart from that, primary human keratinocytes are frequently used for medical studies because the skin provides an important route for drug administration and is readily accessible for biopsies. However, comparability of these cell systems is not known. Cell lines may undergo phenotypic shifts and may differ from the in vivo situation in important aspects. Primary cells, on the other hand, may vary in biological functions depending on gender and age of the donor and localization of the biopsy specimen. Here we employed metabolic labeling in combination with quantitative mass spectrometry-based proteomics to assess A431 and HaCaT cell lines for their suitability as model systems. Compared with cell lines, comprehensive profiling of the primary human keratinocyte proteome with respect to gender, age, and skin localization identified an unexpected high proteomic consistency. The data were analyzed by an improved ontology enrichment analysis workflow designed for the study of global proteomics experiments. It enables a quick, comprehensive and unbiased overview of altered biological phenomena and links experimental data to literature. We guide through our workflow, point out its advantages compared with other methods and apply it to visualize differences of cell lines compared with primary human keratinocytes. PMID:23722187

    Ethnocentrism on the part of health care workers has been documented in the literature and has led to misdiagnosis, mistreatment and undertreatment of culturally diverse individuals worldwide. Aversive Insidious Racism and Ingroup Favoritism theories were used as the guiding framework for this study. Two hundred and sixty-eight female nurses from a large, urban, multi-service hospital in the United States were surveyed to identify those psychosocial variables (age, gender and culture status of the client) which enhanced and/or inhibited their predicted reactions with clients and which have the power to contribute to unethical decision making and less than ethical client care. The findings of this study, which is the first to examine nurses' predicted self and colleague reactions to multiple client variables concurrently, demonstrated that Client Gender as a main effect was not significant in itself when examining self and colleague predictions. Client Age as a main effect was significant for self predictions, p < 0.006, and for colleague predictions, p < 0.000. Client Culture as a main effect was significant for self predictions, p < 0.001 and for colleague predictions, p < 0.001. Many two-way and three-way interaction effects were significant. Subjects consistently predicted more favorable self reactions than colleague reactions, supporting Aversive Insidious Racism theory. Study findings did not consistently support Ingroup Favoritism theory. Subjects did not predict most favorable reactions with Caucasian female clients. PMID:8655268

    Background It is well established that the incidence, prevalence and presentation of mental disorders differ by gender, ethnicity and age, and there is evidence that there is also differential representation in mental health research by these characteristics. The aim of this paper is to a) review the current literature on the nature of barriers to participation in mental health research, with particular reference to gender, age and ethnicity; b) review the evidence on the effectiveness of strategies used to overcome these barriers. Method Studies published up to December 2008 were identified using MEDLINE, PsycINFO and EMBASE using relevant mesh headings and keywords. Results Forty-nine papers were identified. There was evidence of a wide range of barriers including transportation difficulties, distrust and suspicion of researchers, and the stigma attached to mental illness. Strategies to overcome these barriers included the use of bilingual staff, assistance with travel, avoiding the use of stigmatising language in marketing material and a focus on education about the disorder under investigation. There were very few evaluations of such strategies, but there was evidence that ethnically matching recruiters to potential participants did not improve recruitment rates. Educational strategies were helpful and increased recruitment. Conclusion Mental health researchers should consider including caregivers in recruitment procedures where possible, provide clear descriptions of study aims and describe the representativeness of their sample when reporting study results. Studies that systematically investigate strategies to overcome barriers to recruitment are needed. PMID:21126334

    Aim. We assessed obesity, sex, menopause, and gender differences on hypertension in a Hakka-majority Taiwanese sample. Methods. 9621 subjects aged 20 and over participated in this community-based study. Trained nurses collected blood pressure (BP) measurements and anthropometric indices, including weight, height, hip circumference (HC), waist circumference (WC), body mass index (BMI), waist to height ratio (WHtR), and waist to hip ratio (WHR). Results. Levels of systolic and diastolic BP significantly increased at a dose-dependent relationship based on four anthropometric indices (BMI, WC, WHR, and WHtR); the slopes for SBP and DBP differed. After controlling for other covariates using multivariate logistic regression, we found the adjusted odds ratios (OR) of hypertension to be significantly related to the four anthropometric indices. Notably, the effect of obesity on the ORs for hypertension was considerably higher in premenopausal women, but we found no such phenomenon among men. BMI, WC, WHR, and WHtR had significant linear associations with BP. Conclusion. Obesity indices are significantly correlated with the risk of hypertension across gender and age, with BMI having the highest relative potency. The effect of obesity on the risk of hypertension is especially high in premenopausal women, implying a relationship between hormones and hypertension. PMID:25436143

    Aims To determine the prevalence and usage patterns of prescription drugs according to patients' age and gender, and to identify their relative importance in the prescription costs, in primary health care within the Catalan Health Institute. Methods This was a cross-sectional study using computerized pharmacy dispensing records for 5 474 274 members registered, during 2002. Twenty age-gender categories were established. Use of a drug group was defined as filling at least one prescription. The variables studied were age, gender, number of prescriptions and net cost. The prevalence of use, the number of prescriptions and cost issued to each age category were reported. Results The overall prevalence of drug use was 74.53% (women 80.93%, men 67.84%). This was higher in the group of 0–4 year-olds, and in the ≥ 55 year-olds. Age (P < 0.001) produced a statistically more significant effect than gender (P < 0.05). The most used therapeutic groups were analgesics, nonsteroidal anti-inflammatory drugs, antiulcer drugs, anxiolytics, expectorants and mucolytics. The number of prescriptions and costs per patient rose with age and showed great variation in the use of these groups for patients in different age groups. The risk of prescription in women was 23% higher than in men (RR 1.23, 95% CI 1.11, 1.37, P < 0.001). Conclusions The majority of subjects were exposed to one or more drugs. The variability in the number of prescriptions and in the prescribing cost per patient between the different age groups suggests that adjustments should be made for age in practitioners' prescription evaluation processes in primary health care in Catalonia. What is already known about this subject Knowledge of prescription patterns in primary health care is an important tool in rational drug therapy.Age and gender are the principal determining factors of cost variability between medical practices, due to drug prescriptions.Age and gender are the principal determining factors of cost

    The aim of this study is to analyse the influence of performance level, age and gender on pacing during a 100-km ultramarathon. Results of a 100-km race incorporating the World Masters Championships were used to identify differences in relative speeds in each 10-km segment between participants finishing in the first, second, third and fourth quartiles of overall positions (Groups 1, 2, 3 and 4, respectively). Similar analyses were performed between the top and bottom 50% of finishers in each age category, as well as within male and female categories. Pacing varied between athletes achieving different absolute performance levels. Group 1 ran at significantly lower relative speeds than all other groups in the first three 10-km segments (all P < 0.01), and significantly higher relative speeds than Group 4 in the 6th and 10th (both P < 0.01), and Group 2 in the 8th (P = 0.04). Group 4 displayed significantly higher relative speeds than Group 2 and 3 in the first three segments (all P < 0.01). Overall strategies remained consistent across age categories, although a similar phenomenon was observed within each category whereby 'top' competitors displayed lower relative speeds than 'bottom' competitors in the early stages, but higher relative speeds in the later stages. Females showed lower relative starting speeds and higher finishing speeds than males. 'Top' and 'bottom' finishing males displayed differing strategies, but this was not the case within females. Although pacing remained consistent across age categories, it differed with level of performance within each, possibly suggesting strategies are anchored on direct competitors. Strategy differs between genders and differs depending on performance level achieved in males but not females. PMID:26034882

    Measurement of bone turnover in conditions such as osteoporosis has been limited by the need for invasive iliac bone biopsy to reliably determine parameters of bone metabolism. Recent advances in the area of serum and urinary markers of bone metabolism have raised the possibility for noninvasive measurements; however, little nonhuman primate data exist for these parameters. The purpose of this experiment was to define the normal range and variability of several of the newer noninvasive bone markers which are currently under investigation in humans. The primary intent was to determine age and gender variability, as well as provide some normative data for future experiments in nonhuman primates. Twenty-four rhesus macaques were divided into equal groups of male and female according to the following age groupings: 3 years, 5-10 years, 15-20 years, and > 25 years. Urine was collected three times daily for a four-day period and measured for several markers of bone turnoverm including pyridinoline (PYD), deoxypyrodinoline (DPD), hydroxyproline, and creatinine. Bone mineral density measurements of the lumbar spine were performed at the beginning and end of the study period. Serum was also obtained at the time of bone densitometry for measurement of osteocalcin levels by radioimmunoassay. There were no significant differences in bone mineral density, urine PYD, or urine DPD based on gender. Bone density was lowest in the youngest animals, peaked in the 15-20-year group, but again decreased in the oldest animals. The osteocalcin, PYD, and DPD levels followed an inversely related pattern to bone density. The most important result was the relative age insensitivity of the ratio of PYD:DPD in monkeys up to age 20 years. Since bone density changes take months or years to become measurable and iliac biopsies are invasive, the PYD/DPD marker ratio may have important implications for rapid noninvasive measurement of the effects of potential treatments for osteoporosis in the non

    Much research has examined gender and age effects on compensation, concluding that a wage gap exists favoring men and negative stereotypes against older workers persist. Although the effect of an employee's gender or age has been widely studied, little work has examined the impact of the demographic characteristics of a focal employee's immediate referent groups (e.g., subordinates, peers, or supervisors) on pay. The effect of the gender and age composition of a focal manager's subordinates, peers, and supervisor on the manager's compensation levels was investigated in a sample of 2,178 managers across a wide range of organizations and functional areas. After controlling for a number of human capital variables, results indicated that not only does a wage gap favoring men exist, but also managerial pay is lower when managers' referent groups are largely female, when subordinates are outside the prime age group, and when peers and supervisors are younger.

    We aimed to investigate the effects of age and gender on the profile of exhaled volatile organic compounds. We evaluated 68 healthy adult never-smokers, comparing them by age and by gender. Exhaled breath samples were analyzed by an electronic nose (e-nose), resulting in "breathprints". Principal component analysis and canonical discriminant analysis showed that older subjects (≥ 50 years of age) could not be distinguished from younger subjects on the basis of their breathprints, as well as that the breathprints of males could not distinguished from those of females (cross-validated accuracy, 60.3% and 57.4%, respectively).Therefore, age and gender do not seem to affect the overall profile of exhaled volatile organic compounds measured by an e-nose.

    Purpose : To evaluate the normal distribution of exophthalmometric values in Turkish adult population and the effect of age, gender, refractive status and axial length on globe position. Methods : One hundred and twenty-two males and 114 healthy females with age ranging from 18 to 87 years were included in the study. The study population was recruited from patients presenting to our institution for routine refractive examination. Hertel exophthalmometer was used to measure the degree of ocular protrusion. Effect of age, refractive error, interpupillary distance, and axial length on globe position was detected with linear regression analyses. Results : The mean Hertel exophthalmometric size was 15.7+2.6 mm (range; 11 to 21 mm). The mean value for males was 16.1±2.6 mm (range; 11 to 21 mm), and for females 15.5±2.6 mm (range; 11 to 20 mm). The mean distance between the lateral rims of the orbit was 102 + 5.1 mm (range; 88 to 111mm). The mean exophthalmometric values were not statistically different in males and females. Age and mean spherical equivalents were negatively correlated with exophthalmometric measurements. Axial length was positively correlated with exophthalmometric measurements. Conclusion : The exophthalmometric measurement of the eye is affected by the age, spherical equivalent and the axial length. Standard normative values of the Hertel exophthalmometric measurements should be reevaluated with larger samples. PMID:26089994

    2010-01-01

    This contribution is a reply to Dr. Månsdotter's comments on our discussion paper 'Health and well-being in old age: the pertinence of a gender mainstreaming approach in research' published in Gerontology [Gerontology 2010 (in press)]. Even though the comments are interesting and comprehensible, they cannot be left unanswered, this primarily because they are based on weak empirical evidence. (1) It is broadly uncontested that gender is not static. However, the conclusion that the more egalitarian division of parental duties can be viewed as an indicator for reduction of the gender gap in longevity and health is highly speculative. There is not enough empirical evidence to substantiate this position. (2) The 'caring hypothesis' proposed by Månsdotter, which holds that caring fathers develop less risky lifestyles and increased worries, is a possible, but not a sufficient explanation for gender convergence of physical and psychological health in future generations. Such a convergence seems to be heavily co-determined by the changing lifestyles of women. (3) From a lifespan developmental perspective, androgyny does not mean gender equality, but a necessary openness of an individual for the positive traits of the opposing gender role, an essential trait for successful ageing. (4) Månsdotter's doubts concerning the implementation of gender mainstreaming in gerontological research and practice because of society's limited resources are not comprehensible. Exactly because economical resources are limited, and exactly because men and women have different resources and disadvantages due to their specific bio-psycho-social realities, the most efficient way of dealing with the gender gaps in health is with a differentialapproach. (5) The concluding recommendation of Månsdotter for more openness as a scientific position regarding the impact of gender roles on human health and well-being stands in contrast to her claim for normative standpoints and prioritization of either

    An accurate projection for ambulance demand is essential to enable better resource planning for the future that strives to either maintain current levels of services or reconsider future standards and expectations. More than 2 million cases of emergency room attendance in 2008 were obtained from the Hong Kong Hospital Authority to project the demand for its ambulance services in 2036. The projection of ambulance demand in 2036 was computed in consideration of changes in the age-gender structure between 2008 and 2036. The quadratic relation between average daily temperature and daily ambulance demand in 2036 was further explored by including and excluding age-gender demographic changes. Without accounting for changes in the age-gender structure, the 2036 ambulance demand for age groups of 65 and above were consistently underestimated (by 38%-65%), whereas those of younger age groups were overestimated (by 6%-37%). Moreover, changes in the 2008 to 2036 age-gender structure also shift upward and emphasize relationships between average daily temperature and daily ambulance demand at both ends of the quadratic U-shaped curve. Our study reveals a potential societal implication of ageing population on the demand for ambulance services. PMID:23070758

    The ethmoidal foramens are located on the medial wall of the orbit and are key reference points for intraoperative orientation. Detailed knowledge of the anatomy, bony landmarks and morphometric characteristics of the medial wall of the orbit is essential for various surgical procedures. The aim of this study was to determine the morphometric variations in the medial wall of the orbit and establish significant variations regarding age and gender. A total of 110 orbits were analyzed and subdivided by age (over or under 40 years) and gender. The distances of the medial wall of the orbit between the anterior lacrimal crest, the ethmoidal foramen, the optic canal and the interforamina were determined. Safe surgical areas were sought. Statistical tests were used to determine the differences between groups. In men, there is a safe surgical area proximal to the anterior and posterior ethmoidal foramen. In women, this area is in the posterior third of the medial wall of the orbit between the posterior ethmoidal foramen and the optic canal. Regarding variation according to age, the results of this study suggested that the anteroposterior diameter of the medial wall increases with age. This study showed that the anteroposterior total length of the medial orbit wall is similar between genders of similar age, increases with age, and has significant variations in the distances between the various structures that make up the medial orbit wall with regard to gender and age.

    Background. Understanding the physiological, chemical, and biophysical characteristics of the skin helps us to arrange a proper approach to the management of skin diseases. Objective. The aim of this study was to measure 6 biophysical characteristics of normal skin (sebum content, hydration, transepidermal water loss (TEWL), erythema index, melanin index, and elasticity) in a normal population and assess the effect of sex, age, and body location on them. Methods. Fifty healthy volunteers in 5 age groups (5 males and females in each) were enrolled in this study. A multifunctional skin physiology monitor (Courage & Khazaka electronic GmbH, Germany) was used to measure skin sebum content, hydration, TEWL, erythema index, melanin index, and elasticity in 8 different locations of the body. Results. There were significant differences between the hydration, melanin index, and elasticity of different age groups. Regarding the locations, forehead had the highest melanin index, where as palm had the lowest value. The mean values of erythema index and melanin index and TEWL were significantly higher in males and anatomic location was a significant independent factor for all of 6 measured parameters. Conclusion. Several biophysical properties of the skin vary among different gender, age groups, and body locations. PMID:22536139

    Background Given the established links between young age at first intercourse (AFI), number of sex partners, high-risk human papillomavirus infection, and squamous cell cervical cancer (SCC), we hypothesized that women diagnosed with SCC at younger ages would be more likely to report young AFI than women diagnosed later in life. Methods We performed a population-based investigation among invasive SCC cases who were diagnosed between 1986 and 2004, were 22 to 53 years old, and lived in the metropolitan Seattle-Puget Sound region (n=333). Using multivariate linear regression, we estimated coefficients and 95% confidence intervals (CI) to assess the association between age at SCC diagnosis and AFI (<15, 15–18, ≥19) and number of sex partners before age 20 (0, 1, 2–4, 5–14, 15+), accounting for birth year and other factors. Interactions were assessed using the likelihood ratio test. Results The interval between AFI and SCC diagnosis ranged from 4 to 35 years. In a multivariate model, compared to SCC cases reporting AFI≥19, the mean age of diagnosis was 3.1 years younger for SCC cases reporting AFI<15 (CI: −5.8, −0.5) and 2.6 years younger for SCC cases reporting AFI 15–18 years (CI: −4.6, −0.6). Although number of sex partners before age 20 was associated with age at SCC diagnosis in a crude analysis, the association was not independent of AFI. However, in the AFI≥19 and AFI<15 groups, differences in effect were seen by number of sex partners before age 20 (p for interaction=0.08), with the association remaining strong and significant only in the AFI<15 group that had 2 or more partners before age 20 (coefficient: −4.2, CI: −6.3, −2.1). Conclusion Among younger and middle-aged women with SCC, early age of diagnosis was associated with early AFI, though the effect appeared to be modified by number of sex partners before age 20.

    This study examined whether gender moderated the association between age cohort and the cognitive, reflective, and compassionate dimensions of wisdom, using an Iranian sample of 439 adults from three age cohorts: young (18-34), middle-aged (35-54), and older (55 and above). Results indicated that the interaction effect between gender and age cohort was significant for three-dimensional wisdom and all three wisdom dimensions. Compared with younger women and older men, older women tended to have less education and to score lower on the cognitive wisdom dimension, but they had similar average scores as older men on the compassionate wisdom dimension. Overall, the association between age and wisdom was only positive for men, due mainly to the positive relation between age and the reflective and compassionate wisdom dimensions for men after adjusting for education. The results are interpreted with reference to generation gaps, socialization of men versus women, and life experiences and opportunities. PMID:26610721

    The effects of age and gender on sleep EEG power spectral density were assessed in a group of 100 subjects aged 20 to 60 years. We propose a new statistical strategy (mixed-model using fixed-knot regression splines) to analyze quantitative EEG measures. The effect of gender varied according to frequency, but no interactions emerged between age and gender, suggesting that the aging process does not differentially influence men and women. Women had higher power density than men in delta, theta, low alpha, and high spindle frequency range. The effect of age varied according to frequency and across the night. The decrease in power with age was not restricted to slow-wave activity, but also included theta and sigma activity. With increasing age, the attenuation over the night in power density between 1.25 and 8.00 Hz diminished, and the rise in power between 12.25 and 14.00 Hz across the night decreased. Increasing age was associated with higher power in the beta range. These results suggest that increasing age may be related to an attenuation of homeostatic sleep pressure and to an increase in cortical activation during sleep.

    Gender Identity Disorder (GID) is classified as a mental illness and included in the DSM-IV and ICD-1O. It will also be included in the DSM-V. The psychiatric diagnosis, in spite of some apparent advantages, has significant psychological and social adverse implications. This paper discusses some of the main epistemological reasons to consider gender variance as a mental disorder. It will also evaluate whether reasons of other kinds (pragmatic, rather than epistemological) may justify the inclusion of gender variance amongst mental illnesses. PMID:22397088

    We present a case of a 46-year-old transgender male who, during his female-to-male transition, presented with a pituitary apoplexy at the emergency department of a general hospital in the Netherlands. During admission, it turned out that he also suffered from acromegaly due to a growth hormone secreting pituitary adenoma for which he was successfully treated at our university hospital. Previously, his complaints typical of acromegaly were dismissed as attributable to the gender transition. Without the apoplexy, the disease probably would have remained masked by the history of transgenderism for a much longer period of time. It is, therefore, essential to keep looking for additional explanations for new pathology and complaints that cannot typically be attributed to the gender transition in these patients. PMID:24867179

    Bilingualism has been reported to delay the age of retrospective report of first symptom in dementia. This study determined if the age of clinically diagnosed Alzheimer's disease and vascular dementia occurred later for bilingual than monolingual, immigrant and U.S. born, Hispanic Americans. It involved a secondary analysis of the subset of 81 bi/monolingual dementia cases identified at yearly follow-up (1998 through 2008) using neuropsychological test results and objective diagnostic criteria from the Sacramento Area Latino Study on Aging that involved a random sampling of community dwelling Hispanic Americans (N = 1789). Age of dementia diagnosis was analyzed in a 2 × 2 (bi/monolingualism × immigrant/U.S. born) ANOVA that space revealed both main effects and the interaction were non-significant. Mean age of dementia diagnosis was descriptively (but not significantly) higher in the monolingual (M = 81.10 years) than the bilingual (M = 79.31) group. Overall, bilingual dementia cases were significantly better educated than monolinguals, but U.S. born bilinguals and monolinguals did not differ significantly in education. Delays in dementia symptomatology pertaining to bilingualism are less likely to be found in studies: (a) that use age of clinical diagnosis vs. retrospective report of first dementia symptom as the dependent variable; and (b) involve clinical cases derived from community samples rather than referrals to specialist memory clinics.

    Although data for the total number of international migrant flows is now available, no global dataset concerning demographic characteristics, such as the age and gender composition of migrant flows exists. This paper reports on the methods used to generate the CDM-IM dataset of age and gender specific profiles of bilateral net (not gross) migrant flows. We employ raw data from the United Nations Global Migration Database and estimate net migrant flows by age and gender between two time points around the year 2000, accounting for various demographic processes (fertility, mortality). The dataset contains information on 3,713 net migrant flows. Validation analyses against existing data sets and the historical, geopolitical context demonstrate that the CDM-IM dataset is of reasonably high quality. PMID:26692590

    We compared incidence rates of self-reported HIV-related symptoms and illnesses, verified clinical manifestations and findings on physical examination between female and male injecting drug users (IDU) stratified by HIV serostatus in the Amsterdam cohort study on the natural history of HIV infection. HIV-positive female IDU (n = 100) reported a higher frequency of several symptoms and illnesses than male IDU (n = 139). Symptoms were reported more chronically by women compared to men, while clinical manifestations were reported by a greater proportion of women affected by these illnesses compared to men. In HIV-negative IDU (163 women and 232 men) the incidence rates were lower compared to HIV-positives, and a similar gender effect on reported symptoms and illnesses was found. Adjusting for biological, behavioral, demographic and study related variables did not change the gender effect on clinical manifestations substantially. We conclude that the gender effect among HIV-positive IDU was not caused by a differential impact of HIV infection on the incidence of the studied clinical manifestations among female and male IDU, but reflects a higher morbidity of female IDU compared to male IDU.

    Cryptosporidiosis is a worldwide gastrointestinal disease caused by the protozoan Cryptosporidium parasite. It has a broad range of seasonal and age-related prevalence. We aimed to study the molecular prevalence and seasonality of Cryptosporidium over a period of 1 year in a cohort of Egyptian diarrhoeic patients. Stool samples were collected from 865 diarrhoeic patients attending outpatient clinics of Cairo University hospitals, from all age groups over a 12-month period, examined microscopically for faecal Cryptosporidium oocysts by the acid-fast staining method and for copro-DNA detection using nested polymerase chain reaction (nPCR) assays. PCR-positive samples were characterised molecularly by nPCR-restriction fragment length polymorphism (RFLP) to determine Cryptosporidium genotypes. Cryptosporidium copro-DNA was detected in 19.5% of the collected samples throughout the year, with a major peak in summer (August) and a small rise in spring (April). Infection was mainly C. hominis (95.8%) followed by C. parvum (3.0%), affecting all age groups, with predominance in the pre-school age group, and decrease with age. There were statistically significant associations between the detection of Cryptosporidium and season, diarrhoea, patient age and drinking water, while gender, contact with animals and presence of mucus in stool showed no association. Cryptosporidium in diarrhoeic Egyptians was of distinct endemicity, with the bi-model mostly influenced by population dynamics, with a clear high prevalence in pre-school children and predominating anthroponotic (C. hominis) transmission throughout the year. The obtained results highlight Cryptosporidium as a water contaminant and an important cause of health problems in Egypt, necessitating further studies of the risk factors. PMID:26440040

    2015-01-01

    Our ability to differentiate between simple facial expressions of emotion develops between infancy and early adulthood, yet few studies have explored the developmental trajectory of emotion recognition using a single methodology across a wide age-range. We investigated the development of emotion recognition abilities through childhood and adolescence, testing the hypothesis that children’s ability to recognize simple emotions is modulated by chronological age, pubertal stage and gender. In order to establish norms, we assessed 478 children aged 6–16 years, using the Ekman-Friesen Pictures of Facial Affect. We then modeled these cross-sectional data in terms of competence in accurate recognition of the six emotions studied, when the positive correlation between emotion recognition and IQ was controlled. Significant linear trends were seen in children’s ability to recognize facial expressions of happiness, surprise, fear, and disgust; there was improvement with increasing age. In contrast, for sad and angry expressions there is little or no change in accuracy over the age range 6–16 years; near-adult levels of competence are established by middle-childhood. In a sampled subset, pubertal status influenced the ability to recognize facial expressions of disgust and anger; there was an increase in competence from mid to late puberty, which occurred independently of age.

    Our ability to differentiate between simple facial expressions of emotion develops between infancy and early adulthood, yet few studies have explored the developmental trajectory of emotion recognition using a single methodology across a wide age-range. We investigated the development of emotion recognition abilities through childhood and adolescence, testing the hypothesis that children's ability to recognize simple emotions is modulated by chronological age, pubertal stage and gender. In order to establish norms, we assessed 478 children aged 6-16 years, using the Ekman-Friesen Pictures of Facial Affect. We then modeled these cross-sectional data in terms of competence in accurate recognition of the six emotions studied, when the positive correlation between emotion recognition and IQ was controlled. Significant linear trends were seen in children's ability to recognize facial expressions of happiness, surprise, fear, and disgust; there was improvement with increasing age. In contrast, for sad and angry expressions there is little or no change in accuracy over the age range 6-16 years; near-adult levels of competence are established by middle-childhood. In a sampled subset, pubertal status influenced the ability to recognize facial expressions of disgust and anger; there was an increase in competence from mid to late puberty, which occurred independently of age. A small female advantage was found in the recognition of some facial expressions. The normative data provided in this study will aid clinicians and researchers in assessing the emotion recognition abilities of children and will facilitate the identification of abnormalities in a skill that is often impaired in neurodevelopmental disorders. If emotion recognition abilities are a good model with which to understand adolescent development, then these results could have implications for the education, mental health provision and legal treatment of teenagers.

    International statistical data show that compared to men, women are underprivileged in personal resources, such as education and income, physical health and function, and in psychological characteristics, all of which are expressed in lower levels of subjective wellbeing (SWB). Literature shows that SWB is evaluated by numerous scales, which refer to various aspects of SWB. The purpose of this paper is threefold: a) to demonstrate the worldwide phenomenon of gender difference; b) to present a relatively new and unique indicator of wellbeing that is especially appropriate for older adults--the Will-to-Live (WTL), and a scale to evaluate it; c) to examine whether in old age, women differ from men in the strength of their wish to continue living. Results of a series of studies on older persons using the WTL scale indicate that the WTL is a multifaceted generalized indicator of wellbeing that systematically depicts the existing gender differences, indicating that women rank lower on SWB, and have a lower commitment to life than men. The WTL also predicts mortality among women, and is explained by different factors among men and women. As a measure, the WTL is a simple, parsimonious, easy to use tool, and well accepted by older people. Due to its diagnostic and prognostic values, as well as its good psychometric features, the WTL is recommended for practical use in monitoring changes in wellbeing, and evaluating effectiveness of intervention programs directed towards improving the wellbeing of older adults.

    Analysis of variations in normal gait has received considerable attention over the last years. However, most such analyses are carried out on one explanatory variable at a time, and adjustments for other possibly influencing factors are often done using ad hoc methods. As a result, it can be difficult to know whether observed effects are actually a result of the variable under study. We wanted to simultaneously statistically test the effect of gender, age and walking speed on gait in a normal population, while also properly adjusting for the possibly confounding effects of body height and weight. Since point-by-point analysis does not take into account the time dependency in the data, we turned to functional data analysis (FDA). In FDA the whole gait curve is represented not by a set of points, but by a mathematical function spanning the whole gait cycle. We performed several multiple functional regression analyses, and the results indicate that walking speed is the main factor influencing gait in the reference material at our motion analysis laboratory. This effect is also largely unaffected by the presence of other variables in the model. A gender effect was also apparent in several planes and joints, but this effect was often more outspoken in the multiple than in the univariate regression analyses, highlighting the importance of adjusting for confounders like body height and weight.

    Background Doctor–patient communication is a key driver of overall satisfaction with primary care. Patients from minority ethnic backgrounds consistently report more negative experiences of doctor–patient communication. However, it is currently unknown whether these ethnic differences are concentrated in one gender or in particular age groups. Aim To determine how reported GP–patient communication varies between patients from different ethnic groups, stratified by age and gender. Design and setting Analysis of data from the English GP Patient Survey from 2012–2013 and 2013–2014, including 1 599 801 responders. Method A composite score was created for doctor–patient communication from five survey items concerned with interpersonal aspects of care. Mixed-effect linear regression models were used to estimate age- and gender-specific differences between white British patients and patients of the same age and gender from each other ethnic group. Results There was strong evidence (P<0.001 for age by gender by ethnicity three-way interaction term) that the effect of ethnicity on reported GP–patient communication varied by both age and gender. The difference in scores between white British and other responders on doctor–patient communication items was largest for older, female Pakistani and Bangladeshi responders, and for younger responders who described their ethnicity as ‘Any other white’. Conclusion The identification of groups with particularly marked differences in experience of GP–patient communication — older, female, Asian patients and younger ‘Any other white’ patients — underlines the need for a renewed focus on quality of care for these groups.

    Age-related effects are often included as covariates in the analytical model for genome-wide association analysis of quantitative traits reflecting human health. Nevertheless, previous studies have hardly examined the effects of age on the proportion of variation explained by single nucleotide polymorphisms (PVSNP) in these traits. In this study, the PVSNP estimates of body mass index (BMI), waist-to-hip ratio, pulse pressure, high-density lipoprotein cholesterol level, triglyceride level (TG), low-density lipoprotein cholesterol level, and glucose level were obtained from Korean consortium metadata partitioned by gender or by age. Restricted maximum likelihood estimates of the PVSNP were obtained in a mixed model framework. Previous studies using pedigree data suggested possible differential heritability of certain traits with regard to gender, which we observed in our current study (BMI and TG; P < 0.05). However, the PVSNP analysis based on age revealed that, with respect to every trait tested, individuals aged 40 to 49 exhibited significantly lower PVSNP estimates than individuals aged 50 to 59 or 60 to 69 (P < 0.05). The consistent heterogeneous PVSNP with respect to age may be due to degenerated genetic functions in individuals between the ages of 50 and 69. Our results suggest the genetic mechanism of age- and gender-dependent PVSNP of quantitative traits related to human health should be further examined. PMID:25701395

    Frequent upper body bending is associated with low back pain (LBP). The complex flexion movement, combining lumbar and pelvic motion, is known as "lumbopelvic rhythm" and can be quantified by dividing the change in the lumbar spine curvature by the change in pelvic orientation during flexion movement (L/P ratio). This parameter is clinically essential for LBP prevention, for diagnostic procedures and therapy; however, the effects of age and gender, in detail, are unknown. The Epionics SPINE system, utilizing strain-gauge technology and acceleration sensors, was used to assess lumbar lordosis and sacrum orientation during standing and lumbar angle and sacrum orientation during maximal upper body flexion in 309 asymptomatic subjects (age: 20-75 yrs; ♂: 134; ♀: 175). The effects of age and gender on these characteristics as well as on the resultant range of flexion (RoF) and lumbopelvic rhythm were investigated. Aging significantly reduced lumbar lordosis by 8.2° and sacrum orientation by 6.6° during standing in all subjects. With aging, the lumbar RoF decreased by 7.7°, whereas the pelvic RoF compensated for this effect and increased by 7.0°. The L/P ratio decreased from 0.80 to 0.65 with age; however, this decrease was only significant in men. Gender affected sacrum orientation in standing and in flexion as well as the L/P ratio. This study demonstrated the effects of age and gender on lordosis, sacrum orientation and lumbopelvic rhythm. These findings are of importance for the individual prevention of LBP, and provide a baseline for differentiating symptomatic from asymptomatic age- and gender-matched subjects. PMID:26294355

    The primary objective of this study was to evaluate the effect of age, gender, and the use of probiotics with standard treatment regimen on Helicobacter pylori eradication. Based on endoscopic findings and clinical presentation, selected patients were treated with standard triple therapy (omeprazole, clarithromycin, and amoxicillin). Those who failed were offered a repeat treatment with omeprazole, metronidazole, and amoxicillin. After the publications of the possible advantages of probiotic treatment on H pylori eradication, the probiotic agent “Probiotica Forte” was routinely added to the treatment. Eradication was noted for 94/130 patients (72%) and for 128/197 patients (65%) with or without probiotic agent, respectively (P = .23). For second-line treatment eradication was noted in 33/46 (72%) and in 9/20 (45%) with or without probiotic agent, respectively (P = .053). The addition of probiotics may improve eradication success especially in addition to second-line treatment. PMID:27335981

    Large-scale representative surveys of 8th-, 10th-, and 12th-grade students in the United States show high self-esteem scores for all groups. African-American students score highest, Whites score slightly higher than Hispanics, and Asian Americans score lowest. Males score slightly higher than females. Multivariate controls for grades and college plans actually heighten these race/ethnic/gender differences. A truncated scoring method, designed to counter race/ethnic differences in extreme response style, reduced but did not eliminate the subgroup differences. Age differences in self-esteem are modest, with 12th graders reporting the highest scores. The findings are highly consistent across 18 annual surveys from 1991 through 2008, and self-esteem scores show little overall change during that period. PMID:22279425

    Population aging is a key public health issue facing many nations, and is particularly pronounced in many Asian countries. At the same time, attitudes toward filial obligation are also rapidly changing, with a decreasing sense that children are responsible for caring for elderly parents. This investigation blends the family versus nonfamily mode of social organization framework with a life course perspective to provide insight into the processes of ideational change regarding filial responsibility, highlighting the influence of education and international travel. Using data from a longitudinal study in Nepal—the Chitwan Valley Family Study—results demonstrate that education and international travel are associated with a decrease in attitudes toward filial obligation. However, findings further reveal that the impact of education and international travel vary both across the life course and by gender. PMID:25866415

    Introduction Grocery vouchers that specifically target foods associated with reduced cardiovascular disease (CVD) risk result in increased consumption of those foods. In regions with disproportionately high CVD rates, there is little research concerning the impact of vouchers on purchases of risk-reducing foods when there are no restrictions placed on grocery voucher redemption. Since many food assistance programs place few restrictions on type of foods that can be purchased, identifying demographic factors associated with purchasing habits is a prerequisite to promoting healthy eating. The purpose of this study was to determine the associations of age, gender, education and income level with purchasing of healthful foods through the use of a grocery voucher in a rural food desert (poverty rate of ≥20% and ≥33% of residents living >16 km from a large grocery store) with high rates of chronic disease. Methods The effectiveness of an intervention that included a media campaign, a $5 grocery voucher, local heart healthy food branding and a grocery store event was tested. Brief nutritional articles were published in both local newspapers during four consecutive weeks. These articles explained the physiological actions of healthy foods and listed a health-promoting recipe. During the fourth week of the media campaign, a voucher for a $5 grocery gift card redeemable at one of either community grocery stores was also printed in both local newspapers. In each store, foods that are known to be associated with a reduced risk of CVD were marked with a blue logo. Participants (N=311) completed a questionnaire that assessed demographics and usual servings of fruits, vegetables and grains. Participants received a $5 grocery card and a list of labelled foods. Returned grocery receipts were stapled to the questionnaires to analyse the relationship between demographics and food choices. Results Participants who bought at least one labelled food item were older (M=48.5, SD=14

    The current study analyzed the 1999 and 2001 waves of the Nihon University Japanese Longitudinal Study of Aging. Two measures of social integration were associated with lower risks of being physically disabled or depressed at Wave 1 and with a lower risk of progressing into deeper levels of physical disability and depression by Wave 2. Ceteris paribus, compared to elderly urbanites, elderly ruralites had a much higher risk of being physically disabled but much lower odds of being depressed. And compared to elderly men, elderly women had similar risks of being physically disabled but much higher odds of being depressed. Suggestions are made on how future research on longevity in Japan, the world’s most longevous nation, can explore the links among social integration, place, gender, and the postponement of mortality.

    A diary-like instrument to measure lifestyle regularity (the 'Social Rhythm Metric'-SRM) was given to 96 subjects (48 women, 48 men), 39 of whom repeated the study after at least one year, with additional objective measures of rest/activity. Lifestyle regularity as measured by the SRM related to age, morningness, subjective sleep quality and time-of-day variations in alertness, but not to gender, extroversion or neuroticism. Statistically significant test-retest correlations of about 0.4 emerged for SRM scores over the 12-30 month delay. Diary-based estimates of bedtime and waketime appeared fairly reliable. In a further study of healthy young men, 4 high SRM scorers ('regular') had a deeper nocturnal body temperature trough than 5 low SRM scorers ('irregular'), suggesting a better functioning circadian system in the 'regular' group.

    Background In Sweden, the smoking prevalence has declined. In 2007, it was among the lowest in the industrialized world. A steady increase in the use of Swedish oral moist snuff, snus, has occurred in parallel. This development is neither solicited by authorities nor the medical establishment, but rather has occurred along with increased awareness of the dangers of smoking, and has been promoted by product development and marketing of snus. Objective To evaluate time trends in patterns of tobacco use in northern Sweden during 1990–2007. Design Cross-sectional (99,381 subjects) and longitudinal (26,867 subjects) data from the Västerbotten Intervention Programme (VIP) 1990–2007 were analyzed. All adults in Västerbotten County are invited to a VIP health examination at ages 40, 50, and 60 years, and until 1995 also 30 years. Smoking and use of snus were evaluated by gender, age and educational groups. Intermittent smoking was categorized as smoking. Results From the period 1990–1995 to the period 2002–2007, smoking prevalence decreased from 26 to 16% among men and from 27 to 18% among women. The differences in prevalence increased between educational groups. The decline in smoking was less and the increase of snus use was greater among those with basic education. The use of snus among basic-educated 40-year-olds reached 35% among men and 14% among women during 2002–2007. Dual smoking and snus use increased among men and women with basic education. Smoking without snus use was more prevalent among women. Gender differences in total smoking prevalence (smoking only plus dual use) were small in all age groups, but increased among those with basic education reaching 7.3% during 2002–2007, with women being more frequent smokers. Smoking prevalences were similar among never, former and current snus users. Among the 30,000 former smokers, 38% of men and 64% of women had never used snus. Longitudinal data showed a decline in total tobacco use from baseline until

    In the adult dog, kidney length has been reported as 2.98 ± 0.44 times the length of L2 on ventrodorsal views and 2.79 ± 0.46 times the length of L2 on lateral radiographs. Our aim was to test the hypothesis that the suggested maximum normal left kidney size is too high, and to evaluate the effect of breed type, gender, weight and age of the dog on kidney size. Abdominal radiographs of 200 dogs with no evidence of concurrent disease that might have an effect on renal size were included in the study. The mean ratio of kidney length to the second lumbar vertebra length was similar to previous reports. For the right lateral view it measured 2.98 ± 0.60 and for the ventrodorsal view 3.02 ± 0.66. Significant differences of this ratio between skull type were present, especially between brachycephalic and dolichocephalic dogs. On the right lateral view brachycephalic dogs had the highest median LK/L2 ratio of 3.1 (3.20 ± 0.40), whereas for dolichocephalic dogs it was 2.8 (2.82 ± 0.50), and for mesaticephalic dogs it was 2.97 (3.01 ± 0.6). A ratio >3.5 was found only in mesaticephalic dogs on the ventrodorsal view. There was a significant difference in the LK/L2 ratio between small (≤10kg) and large breed dogs (>30kg) where small dogs had a significantly higher LK/L2 ratio. There was no statistically significant relation between this ratio and age or gender. The previously reported ratios for kidney size seem valid, but because skull type has an impact on the LK/L2 ratio, a single normal ratio should not be used for all dogs. PMID:22537277

    The effects of month of birth (MOB) on life expectancy of a German subpopulation was investigated. Data from people who died in North Rhine Westphalia in the years 1984 (n=188,515) and 1999 (n=188,850) were analyzed. For comparative purposes, all deaths that occurred at an age of <50 years were excluded (1984: 8.4%; 1999: 6.2%). In general, individuals born in May through July had the lowest age at death (1984: 75.27±0.09 years; 1999: 77.58±0.09 years), while those born between October and December had the highest (1984: 75.98±0.08 years; 1999: 78.35±0.09 years), supporting earlier findings. The observed amplitudes (differences between highest and lowest values) were more pronounced in men than in women. When comparing these data of MOB effects on life expectancy with earlier findings in Australia, Austria, Denmark, Ukraine, and the USA, it is evident that a negative correlation exists between the average age at death and the MOB amplitudes. Separate analyses by gender, possible for the data from Germany, the Ukraine, and the USA, revealed a significant negative correlation for men, but not for women. A new hypothesis is therefore presented describing an influence of life quality, as reflected by average life expectancy, on the extent of MOB effects; for example, seasonally variable sensitivities during pregnancy/early childhood.

    The ability to attribute different mental states to distinct individuals, or Theory of Mind (ToM), is widely believed to be developed mostly during preschool years. How different factors such as gender, number of siblings, or coarse personality traits affect this development is not entirely agreed upon. Here, we introduce a computerized version of the scaled ToM suite of tasks introduced by Wellman and Liu (2004), which allows us to meaningfully test ToM development on children 6 to 8-years old. We find that kids this age are still not entirely proficient in all ToM tasks, and continue to show a progression of performance with age. By testing this new age range, too, we are able to observe a significant advantage of girls over boys in ToM performance. Other factors such as number of siblings, birth order, and coarse personality traits show no significant relation with the ToM task results. Finally, we introduce a novel way to quantify the scaling property of the suite involving a sequence of set inclusions on one hand and a comparison between specially tailored sets of logistic models on the other. These measures confirm the validity of the scale in the 6- to 8-years old range. PMID:23785326

    The goal of this paper is to determine concentrations of seven selected perfluoroalkylated substances (PFASs): perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorohexane sulfonic acid (PFHxS), perfluorononanoic acid (PFNA), perfluorodecanoic acid (PFDA), perfluoroundecanoic acid (PFUnDA), perfluorododecanoic acid (PFDoDA) in the blood serum of men and women of reproductive age from the central region of Poland. The relation between sex of tested subjects and the levels of compounds in blood serum of humans will also be considered and analysed as an element of the risk assessment. The study was made on the blood serum samples collected from 253 women and 176 men of reproductive age between 20 and 44 years from Warsaw and surrounding areas. Higher concentrations of five (PFOS, PFOA, PFNA, PFDA, PFUnDA) from among seven selected PFASs were observed in men in comparison to women from the same populations. Only the concentrations of PFHxS and PFDoDA were slightly higher in women than in men. These differences were statistically significant in all cases, except for PFUnDA. The hypothesis that the concentrations of said compounds increase with age of the test subjects, regardless of gender has not been confirmed. PMID:26100734

    The dramatic rise in the number of refugees entering Germany means that age estimation for juveniles and young adults whose age is unclear but relevant to legal and official procedures has become more important than ever. Until now, whether and to what extent the combination of methods recommended by the Study Group on Forensic Age Diagnostics has resulted in a reduction of the range of scatter of the summarized age diagnosis has been unclear. Hand skeletal age, third molar mineralization stage and ossification stage of the medial clavicular epiphyses were determined for 307 individuals aged between 10 and 29 at time of death on whom autopsies were performed at the Institutes of Legal Medicine in Berlin, Frankfurt am Main and Hamburg between 2001 and 2011. To measure the range of scatter, linear regression analysis was used to calculate the standard error of estimate for each of the above methods individually and in combination. It was found that combining the above methods led to a reduction in the range of scatter. Due to various limitations of the study, the statistical parameters determined cannot, however, be used for age estimation practice. PMID:26934764

    Aim of the study Gleason score stratification according to age at diagnosis has been retrospectively evaluated in 1028 men with biopsy-proven prostate cancer (PCa). Material and methods From January 2006 to December 2014, 2435 Caucasian men aged between 37 and 92 years underwent transperineal prostate biopsy for suspicion of PCa. The indications were as follows: abnormal digital rectal examination (DRE), PSA values > 10 ng/ml or between 4.1–10 or 2.6–4 ng/ml, with free/total PSA < 25% and < 20%, respectively. Results In 1028 (42.2%) patients with median PSA of 9.6 ng/ml a PCa was found (median age 62.3 years; range: 42–92 years); 757 (73.7%) vs. 271 (26.3%) men had a T1c vs. T2 clinical stage, respectively. Median Gleason score was 7 (range: 6–10). The Gleason score progressively increased with the age of the patients at diagnosis, and a significantly correlation between Gleason score ≥ 8 and men older than 80 years was demonstrated (p = 0.0001). Conclusions The detection rate of aggressiveness of PCa progressively increased with the age at diagnosis; Gleason score ≥ 8 was more frequently diagnosed in men older than 80 years with PSA values > 10 ng/ml (about 80% of the cases) and abnormal DRE (about 60% of the cases).

    2015-01-01

    ABSTRACT The purpose of the study is to examine healthy eating habits of the population of Serbia through three dimensions: knowledge, problems, and feelings as well as to determine whether there are any differences between genders and among different age-groups. The research instrument was an Eating Habits Questionnaire (EHQ) which consisted of 35 items. There were 382 respondents involved in the study. The reliability and factor structure of the questionnaire were verified by using factor analysis. The results of MANOVA showed that there is a significant difference in the habits concerning healthy eating between men and women [F (3,378)=4.26, p=0.006; Wilks’ Lambda=0.97]. When the results for the dependent variables (knowledge, problems, and feelings) were considered separately, it was determined that there is no significant difference between men and women, which confirms the results of the t-test. The effect of age on the three dimensions of healthy eating habits was examined within three age-groups, by using ANOVA. The results showed that knowledge about healthy eating increases with age [F (2,379)=6.14, p=0.002] as well as positive feelings which occur as a result of healthy eating [F (2,379)=3.66, p=0.027]. Unlike ANOVA, MANOVA showed difference among the age-groups only when it came to the ‘knowledge’ variable. This study is important as it shows the current state of awareness on healthy eating habits in the researched populace and may be the basis for further research in this field in Serbia.

    ICD-11 (the eleventh edition of the World Health Organization International Statistical Classification of Diseases and Related Health Problems) is due for approval in 2018. For transgender health care, the most important proposals for ICD-11 are as follows: (1) the five ICD-10 diagnoses (most notably Transsexualism and Gender Identity Disorder of Childhood) currently in Chapter 5 (Mental and Behavioural Disorders) will be replaced by two Gender Incongruence diagnoses, one of Adolescence and Adulthood and the other of Childhood (GIC), and (2) these two diagnoses will be located in a new chapter provisionally named Conditions Related to Sexual Health. Debate on the GIC proposal has focused on whether there should be a diagnosis for young children exploring their identity and has drawn on a number of arguments for and against the proposal. The World Professional Association for Transgender Health conducted a survey to examine members' views concerning the GIC proposal, as well as an alternative framework employing non-pathologizing Z Codes. The survey was completed by 241 (32.6 %) out of 740 members. Findings indicated an even split among members regarding the GIC proposal (51.0 % [n = 123] opposing and 47.7 % [n = 115] supporting the proposal). However, non-US members were overall opposed to the proposal (63.9 % [n = 46] opposing, 36.1 % [n = 26] supporting). Across the sample as a whole, and among those expressing a view about Z Codes, there was substantial support for their use in healthcare provision for children with gender issues (35.7 % [n = 86] of the sample supporting vs. 8.3 % [n = 20] rejecting).

    Objective The length of anterior-posterior commissure (AC-PC) in racial groups, age, gender of patients with deep brain stimulation (DBS) and pallidotomy were investigated. Methods From January 1996 to December 2003, 211 patients were treated with DBS and pallidotomy. There were 160 (76%) Caucasians, 35 (17%) Hispanics, 12 (5%) Asians and 4 Blacks (2%). There were 88 males and 52 females in DBS-surgery group and 44 males, 27 females in pallidotomy group. Mean age was 58 year-old. There were 19 males and 19 females and mean age was 54.7 years in the control group. Measurements were made on MRI and @Target software. Results The average AC-PC distance was 24.89 mm (range 32 to 19), which increased with aging until 75 years old in Caucasian and also increased with aging in Hispanic, but the AC-PC distance peaked at 45 years old in Hispanic. The order of AC-PC distance were 25.2±2 mm in Caucasian, 24.6±2.24 mm in Asian, 24.53 mm in Black, 23.6±1.98 mm in Hispanic. The average AC-PC distance in all groups was 24.22 mm in female who was mean age of 56.35, 25.28 mm in male who was mean age of 60.19 and 24.5±2 mm in control group that was excluded because of the difference of thickness of slice. According to multiple regression analysis, the AC-PC distance was significantly correlated with age, race, and gender. Conclusion The AC-PC distance is significantly correlated with age, gender, and race. The atlas of functional stereotaxis would be depended on the variation of indivisual brain that can influenced by aging, gender, and race. PMID:19096609

    Obesity is a main global health issue and an outstanding cause of morbidity and mortality predisposing to type 2 diabetes (T2DM) and cardiovascular diseases. Huge research efforts focused on gene expression, cellular signalling and metabolism in obesity have improved our understanding of these disorders; nevertheless, to bridge the gap between the regulation of gene expression and changes in signalling/metabolism, protein levels must be assessed. We have extensively analysed visceral adipose tissue from age-, T2DM- and gender-matched obese patients using high-throughput proteomics and systems biology methods to identify new biomarkers for the onset of T2DM in obesity, as well as to gain insight into the influence of aging and gender in these disorders. About 250 proteins showed significant abundance differences in the age, T2DM and gender comparisons. In diabetic patients, remarkable gender-specific hallmarks were discovered regarding redox status, immune response and adipose tissue accumulation. Both aging and T2DM processes were associated with mitochondrial remodelling, albeit through well-differentiated proteome changes. Systems biology analysis highlighted mitochondrial proteins that could play a key role in the age-dependent pathophysiology of T2DM. Our findings could serve as a framework for future research in Translational Medicine directed at improving the quality of life of obese patients. PMID:27160966

    Dietary patterns are linked to obesity, but the gender difference in the association between dietary patterns and obesity remains unclear. We explored this gender difference in a middle-aged and elderly populations in Shanghai. Residents (n = 2046; aged ≥45 years; 968 men and 1078 women) who participated in the Shanghai Food Consumption Survey were studied. Factor analysis of data from four periods of 24-h dietary recalls (across 2012–2014) identified dietary patterns. Height, body weight, and waist circumference were measured to calculate the body mass index. A log binominal model examined the association between dietary patterns and obesity, stratified by gender. Four dietary patterns were identified for both genders: rice staple, wheat staple, snacks, and prudent patterns. The rice staple pattern was associated positively with abdominal obesity in men (prevalence ratio (PR) = 1.358; 95% confidence interval (CI) 1.132–1.639; p = 0.001), but was associated negatively with general obesity in women (PR = 0.745; 95% CI: 0.673–0.807; p = 0.031). Men in the highest quartile of the wheat staple pattern had significantly greater risk of central obesity (PR = 1.331; 95% CI: 1.094–1.627; p = 0.005). There may be gender differences in the association between dietary patterns and obesity in middle-aged and elderly populations in Shanghai, China. PMID:27455322

    OBJECTIVE: To study the health-seeking behaviour of elderly members (aged > 60 years) of households in rural Bangladesh, to ascertain how their behaviour differs from that of younger people (aged 20-59 years) living in the same household and to explore the determinants of health-seeking behaviour. METHODS: Structured interviews were conducted to elicit information on the health-seeking behaviour of household members aged > 20 years. Respondents were asked about major illnesses occurring within 15 days prior to the interview. The sample consisted of 966 households that had at least one resident who was aged > 60 (32% of 3031 households). FINDINGS: We found no major differences in health-seeking behaviour between elderly people and younger adults. On average about 35% (405/1169) of those who reported having been ill during the previous 15 days in both age groups chose self-care/self-treatment; for both age groups the most commonly consulted type of provider was a paraprofessional such as a village doctor, a medical assistant or a community health worker. A household's poverty status emerged as a major determinant of health-seeking behaviour. The odds ratio (OR) that individuals from poor households would seek treatment from unqualified allopathic practitioners was 0.6 (95% confidence interval (CI) = 0.40-0.78); the odds ratio that individuals from poor households would seek treatment from qualified allopathic practitioners was 0.7 (95% CI = 0.60-0.95). For self-care or self-treatment it was 1.8 (95% CI = 1.43-2.36). Patients' level of education affected whether they avoided self-care/self-treatment and drugstore salespeople (who are usually unlicensed and untrained but who diagnose illnesses and sell medicine) and instead chose a formal allopathic practitioner (OR = 1.5; 95% CI = 1.15-1.96). When a household's poverty status was controlled for, there were no differences in age or gender in terms of health-care expenditure. CONCLUSION: We found that socioeconomic

    This study explored how women's and men's gendered experiences from childhood to old age have shaped their vulnerability in relation to HIV both in terms of their individual risk of HIV and their access to and experiences of HIV services. It was a small scale-scale study conducted in urban and rural sites in Uganda between October 2011 and March 2012. The study used qualitative methods: in-depth interviews (with 31 participants) and focus group discussions (FGDs) with older women (2) and men (2) in urban and rural sites and 7 key informant interviews (KIIs) with stakeholders from government and non-government agencies working on HIV issues. Women's position, the cultural management of sex and gender and contextual stigma related to HIV and to old age inter-relate to produce particular areas of vulnerability to the HIV epidemic among older women and men. Women report the compounding factor of gender-based violence marking many of their sexual relationships throughout their lives, including in older age. Both women and men report extremely fragile livelihoods in their old age. Older people are exposed to HIV through multiple and intersecting drivers of risk and represent an often neglected population within health systems. Research and interventions need to go beyond only conceptualising older people as 'carers' to better address their gendered vulnerabilities to HIV in relation to all aspects of policy and programming.

    Introduction Female gender is a known risk factor for early and late mortality after coronary artery bypass graft surgery (CABG). Higher age of women at operation may influence outcome, since age per se is also an important risk factor. The purpose of our study was to analyze possible gender differences in outcome after isolated CABG in different age groups to delineate the impact of female gender and age. Methods All patients over 60 years of age undergoing isolated CABG at our department during 2001 and 2011 were included and categorized by age into sexagenarians (2266, 16.6% women), septuagenarians (2332, 25.4% women) and octogenarians (374, 32% women) and assessed by gender for 30-day and 180-day mortality. Results Thirty-day mortality was significantly higher in women only amongst septuagenarians (7.1 vs. 4.7%, p = 0.033). Same differences apply for 180-day mortality (12.3 vs. 8.2%, p = 0.033) and estimated one-year survival (81.6 ± 4.2 vs. 86.9 ± 2.2%, p = 0.001). Predictive factors for 30-day mortality of septuagenarian were logistic EuroSCORE (ES) (p = 0.003), perioperative myocardial infarction (MI) (p<0.001), pneumonia (p<0.001), abnormal LV-function (p<0.04) and use of LIMA graft (p<0.001), but not female gender. However, female gender was found to be an independent predictor for 180-day mortality (HR 1.632, p = 0.001) in addition to ES, use of LIMA graft, perioperative MI, pneumonia and abnormal LV function (HR 1.013, p = 0.004; HR 0.523, p<0.001; HR 2.710, p<0.001; HR 3.238, p<0.001; HR 2.013, p<0.001). Conclusion Women have a higher observed probability of early death after CABG in septuagenarians. However, female gender was not found to be an independent risk factor for 30-day, but for 180-day survival. Therefore, reduction of high impact risk factors such as perioperative MI and enhancement of LIMA use should be future goals. In view of our findings, decision for surgical revascularization should not be based on gender. PMID:26845158

    Brain volume and thickness abnormalities have been reported in first-episode psychosis (FEP). However, it is unclear if and how they are modulated by brain developmental stage (and, therefore, by age at FEP as a proxy). This is a multicenter cross-sectional case-control brain magnetic resonance imaging (MRI) study. Patients with FEP (n = 196), 65.3% males, with a wide age at FEP span (12-35 y), and healthy controls (HC) (n = 157), matched for age, sex, and handedness, were scanned at 6 sites. Gray matter volume and thickness measurements were generated for several brain regions using FreeSurfer software. The nonlinear relationship between age at scan (a proxy for age at FEP in patients) and volume and thickness measurements was explored in patients with schizophrenia spectrum disorders (SSD), affective psychoses (AFP), and HC. Earlier SSD cases (ie, FEP before 15-20 y) showed significant volume and thickness deficits in frontal lobe, volume deficits in temporal lobe, and volume enlargements in ventricular system and basal ganglia. First-episode AFP patients had smaller cingulate cortex volume and thicker temporal cortex only at early age at FEP (before 18-20 y). The AFP group also had age-constant (12-35-y age span) volume enlargements in the frontal and parietal lobe. Our study suggests that age at first episode modulates the structural brain abnormalities found in FEP patients in a nonlinear and diagnosis-dependent manner. Future MRI studies should take these results into account when interpreting samples with different ages at onset and diagnosis. PMID:26371339

    Dexterous manipulation depends on using the fingertips to stabilize unstable objects. The Strength–Dexterity paradigm consists of asking subjects to compress a slender and compliant spring prone to buckling. The maximal level of compression [requiring low fingertip forces <300 grams force (gf)] quantifies the neural control capability to dynamically regulate fingertip force vectors and motions for a dynamic manipulation task. We found that finger dexterity is significantly affected by age (p = 0.017) and gender (p = 0.021) in 147 healthy individuals (66F, 81M, 20–88 years). We then measured finger dexterity in 42 hands of patients following treatment for osteoarthritis of the base of the thumb (CMC OA, 33F, 65.8 ± 9.7 years), and 31 hands from patients being treated for Parkinson’s disease (PD, 6F, 10M, 67.68 ± 8.5 years). Importantly, we found no differences in finger compression force among patients or controls. However, we did find stronger age-related declines in performance in the patients with PD (slope −2.7 gf/year, p = 0.002) than in those with CMC OA (slope −1.4 gf/year, p = 0.015), than in controls (slope −0.86 gf/year). In addition, the temporal variability of forces during spring compression shows clearly different dynamics in the clinical populations compared to the controls (p < 0.001). Lastly, we compared dexterity across extremities. We found stronger age (p = 0.005) and gender (p = 0.002) effects of leg compression force in 188 healthy subjects who compressed a larger spring with the foot of an isolated leg (73F, 115M, 14–92 years). In 81 subjects who performed the tests with all four limbs separately, we found finger and leg compression force to be significantly correlated (females ρ = 0.529, p = 0.004; males ρ = 0.403, p = 0.003; 28F, 53M, 20–85 years), but surprisingly found no differences between dominant and non-dominant limbs.

    The relationship between thyroid-stimulating hormone (TSH) and hyperlipidemia is still a topic of debate. We aimed to explore the impact of gender and age on the association between serum TSH and lipid profile in a large cohort of Chinese.This cross-sectional study enrolled 13,915 participants (8565 male, 5350 female), who self-reported as healthy without any known previous diseases. Clinical data including anthropometric measurements, thyroid function, and other serum parameters were collected. The associations between TSH and hyperlipidemia of males and females were analyzed separately after dividing TSH and age into subgroups. Odds ratio for hyperlipidemia was calculated by binary logistic regression models.Young males had significantly higher prevalence of hypercholesterolemia, hypertriglyceridemia, and high serum low-density lipoprotein-cholesterol than females, yet after menopause, females had higher prevalence than males. TSH was positively associated with hyperlipidemia independent of thyroid hormones. Males showed more reduced risks of hyperlipidemia in low TSH concentrations, while females demonstrated more enhanced risks of hyperlipidemia in high TSH concentrations. For instance, if TSH was lower than 0.3 μIU/mL, the risks of developing hypercholesterolemia and hypertriglyceridemia in males were only 0.198 (P < 0.01) and 0.425 (P < 0.05) of the reference TSH risks (between 2.0 and 3.0 μIU/mL), while in females the risks were 0.553 (P < 0.05) and 0.642 (P > 0.05), respectively. If TSH was higher than 4.0 μIU/mL, women displayed significantly higher risks of developing hypertriglyceridemia than the reference TSH risks (P < 0.05), yet, men did not demonstrate such significances.Our results showed thyroid hormone independent positive associations between serum TSH and lipids, which were substantially influenced by gender and age. Males demonstrated more protective effects of low TSH against hyperlipidemia, while females showed

  8. Queensland general practitioners' applications of the "mature minor" principle: the role of patient age and gender.

    Most Australian jurisdictions do not have legislation that stipulates an age by which a minor can make their own medical treatment decisions. Instead, they rely on Gillick v West Norfolk and Wisbech Area Health Authority [1986] AC 112, an English common law decision that recommends individual assessments of "maturity". This study explores how medical practitioners in the State of Queensland understand and apply this legal authority when faced with a young person wishing to make a contentious medical treatment decision. Almost 200 doctors made decisions about a hypothetical patient's competence and confidentiality, and detailed their reasoning in an open-ended format. The data indicate that the vagaries of existing legal criteria allow for a range of philosophical perspectives and idiosyncratic heuristics to play a role in assessment practices, and that particular combinations of patient age and gender made these cognitive shortcuts more likely to occur. A notable proportion of such processes are not consistent with legal guidelines, and this has implications for general practitioners' vulnerability to litigation as well as young patients' treatment trajectories.

    To investigate effects of visual experience versus preprogrammed mechanisms on visual development, we used multiple regression analysis to determine the extent to which a variety of variables (that differ in the extent to which they are tied to visual experience) predict luminance and chromatic (red/green) contrast sensitivity (CS), which are mediated by the magnocellular (M) and parvocellular (P) subcortical pathways, respectively. Our variables included gestational length (GL), birth weight (BW), gender, postnatal age (PNA), and birth order (BO). Two-month-olds (n = 60) and 6-month-olds (n = 122) were tested. Results revealed that (1) at 2 months, infants with longer GL have higher luminance CS; (2) at both ages, CS significantly increases over a ~21-day range of PNA, but this effect is stronger in 2- than 6-month-olds and stronger for chromatic than luminance CS; (3) at 2 months, boys have higher luminance CS than girls; and (4) at 2 months, firstborn infants have higher CS, while at 6 months, non-firstborn infants have higher CS. The results for PNA/GL are consistent with the possibility that P pathway development is more influenced by variables tied to visual experience (PNA), while M pathway development is more influenced by variables unrelated to visual experience (GL). Other variables, including prenatal environment, are also discussed. PMID:19810800

    This research examines relationships between different forms of aerobic exercise (swim, walk, jog, dance) and two measures of health: subjective health and psychological well-being. We hypothesize that the relationship between aerobic exercise and subjective health/well-being will be notably stronger for older than younger persons and females than males. This prediction is based on Homans' exchange theory of investments and rewards. Since social norms concerning aerobic exercise are likely to be weaker among older (than younger) persons and among women than men, older persons and women who do exercise are making special investments and should expect greater rewards (good health). The concept of 'exercise norms' implies social comparisons with others. Accordingly, age comparative data were analyzed to see if older persons who exercise see themselves as more active than their age peers than do younger persons. Data come from a national probability sample of 3025 adults (National Survey of Personal Health Practices and Consequences). As predicted, exercise was much more strongly related to subjective health and well-being among older than younger respondents. In the main, the gender hypothesis was not supported. PMID:8771638

    2015-01-01

    Objectives. This paper tests whether differences by gender and by educational attainment in contact with friends and family and in support expected from friends and family narrow or widen in late middle age. Methods. The data are drawn from about 4,800 members of the Wisconsin Longitudinal Survey who answered questions about their frequency of contact with social ties and expectations of 3 kinds of help in both 1993, when they were in their early 50s, and again in 2004. Results. Using lagged dependent variable models, we find that between their 50s and 60s women’s network advantages over men and college graduates’ network advantages over high school graduates in frequency of social contact widened. The same was roughly true as well for expectations of social support, although here the divergences depended partly on the type of the support: Women gained relative to men in “talk” support and in help from nonkin if ill, but lost ground in financial support. The college-educated gained ground in all sorts of support from nonkin. Discussion. These results reinforce concern that late middle age is a period when men and the less educated become yet more disadvantaged in social support, making attention to connectedness yet more critical.

    Leptin is involved in the regulation of food intake and energy expenditure, and therefore, is central to adipositysensing pathway. We examined the relationship of the leptin G-2548A polymorphism with obesity and obesityrelated anthropometric and metabolic parameters in a total of 394 (239 obese and 155 non-obese) subjects between 5 and 45 years of age. Body weight, height, waist circumference (WC), hip circumference (HC) and blood pressure (BP) were measured. Body mass index (BMI) and waist-to-hip ratio (WHR) were calculated. Levels of fasting blood glucose (FBG), insulin, leptin and leptin receptor were determined, and homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. Genotyping was carried out by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The LEP G-2548A polymorphism showed association with obesity in children and adolescents (less than or equal to 18 years of age) but not in adults. However, analysis by gender stratification revealed association with obesity in girls only. In addition, G-2548A polymorphism showed association with BMI, WC, HC, fasting blood glucose and serum leptin levels. This suggests that G-2548A polymorphism may influence the susceptibility to metabolic disturbances and obesity at an early life. Further investigation with a larger sample size is required to validate the effect of LEP G-2548A polymorphism in obese Pakistani girls. PMID:26333398

  13. Bad Marriage, Broken Heart? Age and Gender Differences in the Link between Marital Quality and Cardiovascular Risks among Older Adults

    2015-01-01

    Working from a life course perspective, we develop hypotheses about age and gender differences in the link between marital quality and cardiovascular risk and test them using data from the first two waves of the National Social Life, Health, and Aging Project. The analytic sample includes 459 married women and 739 married men (aged 57–85 in the first wave) who were interviewed in both waves. We apply Heckman-type corrections for selection bias due to mortality and marriage. Cardiovascular risk is measured as hypertension, rapid heart rate, C-reactive protein, and general cardiovascular events. Results suggest that changes in marital quality and cardiovascular risk are more closely related for older married people than for their younger counterparts; and that the link between marital quality and cardiovascular risk is more pronounced among women than among men at older ages. These findings fit with the gendered life course perspective and cumulative disadvantage framework. PMID:25413802

    2014-01-10

    Objective: The aim was to examine associations of age and gender with ADHD subtypes and subsequently to examine associations of age, gender, and subtypes with comorbid psychiatric disorders. Method: Odds ratios were calculated and logistic regression performed using information from a clinical sample of 155 ADHD adults referred to a Danish specialized ADHD unit from 2010 to 2011. Results: A majority of men (65%) was found in the sample. Most patients were subtyped ADHD combined (78%), followed by ADHD inattentive (18%), and ADHD hyperactive-impulsive (4%). No significant differences were found in gender and age across subtypes. Current comorbid disorders were found in 57% of the ADHD patients. Significantly more comorbidity was found in the ADHD combined type and in patients ≥25 years. Significantly more men had substance use disorders and significantly more women had personality disorders. Conclusion: When assessing adult ADHD patients' age, gender, subtype, and related comorbid symptom profiles should be taken into account. (J. of Att. Dis. XXXX; XX(X) XX-XX). PMID:24412968

    2015-01-01

    Objective: The aim of this study is to use diffusion-weighted MRI to assess the apparent diffusion coefficient (ADC) values in head, body and tail sections of the pancreas in healthy subjects and the relationships between these values and age, gender and body mass index (BMI) of these cases. Methods: This study was conducted on 82 participants who were referred to the Tabesh Medical Imaging Center, Tabriz, Islamic Republic of Iran, during 2013. Echo-planar diffusion-weighted imaging of the pancreas was carried out with b-values of 50, 400 and 800 s mm−2, and ADC values were assessed for the head, body and tail sections of the pancreas. Results: The ADC values for the head, body and tail sections of the pancreas in female participants were significantly greater than those in male subjects (p < 0.05). ADC values for these parts among subjects with different BMI differed significantly (p < 0.05). Regarding age, there were no statistically meaningful differences among the ADC values for the three parts (p > 0.05). Conclusion: Gender and BMI effect the ADC values of the three sections of the pancreas. Thus, knowledge of the basic values based on gender and BMI can improve diagnostics. Having looked at age factor, it seems that the ADC values were not significantly different. Advances in knowledge: According to the results pancreatic ADC values appear to be influenced by gender and BMI but not by age. PMID:25471056

    Vitamin E (VitE) only prevented cardiovascular diseases in some patients and the mechanisms remain unknown. VitE levels can be affected by aging and gender. We hypothesize that age and gender can influence VitE’s cardioprotective effect. Mice were divided into 4 groups according to age and gender, and each group of mice were divided into a control group and a VitE group. The mice were administered water or VitE for 21 days; Afterward, the cardiac function and myocardial infarct size and cardiomyocyte apoptosis were measured after myocardial ischemia reperfusion(MI/R). VitE may significantly improved cardiac function in young male mice and aged female mice by enhancing ERK1/2 activity and reducing JNK activity. Enhanced expression of HSP90 and Bcl-2 were also seen in young male mice. No changes in cardiac function and cardiac proteins were detected in aged male mice and VitE was even liked to exert a reverse effect in cardiac function in young mice by enhancing JNK activity and reducing Bcl-2 expression. Those effects were in accordance with the changes of myocardial infarction size and cardiomyocyte apoptosis in each group of mice. VitE may reduce MI/R injury by inhibiting cardiomyocyte apoptosis in young male mice and aged female mice but not in aged male mice. VitE was possibly harmful for young female mice, shown as increased cardiomyocyte apoptosis after MI/R. Thus, we speculated that the efficacy of VitE in cardiac protection was associated with age and gender. PMID:26331272

    Background: Neurocognitive tests are routinely used to assess cognitive domains in the adolescents for assessing cognitive deficits and for therapeutic interventions. Now they are being used to assess their mental abilities in athletics too. Aim: To study the effect of age and gender differences on routinely used common paper and pencil neuro-cognitive tests in adolescents and present the trends of normative data of Indian adolescent population. Settings and Design: Present study was conducted as a joint collaboration between Department of Physiology and Jawahar Navodaya school, Puducherry, India. Materials and Methods: Four hundred and thirty nine adolescents in the age group of 12 to 17 y (M = 250, F= 189) were selected in the present study after meeting the inclusion and exclusion criteria. Subjects were administered commonly used paper and pencil neuropsychological tests in the following order: Two Target Letter Cancellation test, Trail Making test A and B, Ruff Figural Fluency test (RFFT). Statistical Analysis: We divided the students based on their age into six groups - from age 12–17. Neurocognitive parameters were compared between these age groups using one-way-ANOVA with Bonferroni post-hoc test. Only the p-values for one, two and three year difference were considered. The same analysis was repeated for each gender separately. We compared males and females from the entire sample using unpaired t test. We then repeated the same test to compare males and females in each age group separately. Pearsons correlation was done to find correlation between the neurocognitive test parameters using the entire sample size. Then the correlation was done again after adjusting for age. All the statistical analysis was done using Statistical package for social sciences (SPSS) version 19. Results: Year wise normative data has been presented for all the age groups from 12 y onwards to 17 y. The results showed a consistent improvement in performance on the tested neuro

    Objectives. To examine gender disparities in cognitive functioning in India and the extent to which education explains this disparity in later life. Methods. This study uses baseline interviews of a prospective cohort study of 1,451 community-residing adults 45 years of age or older in four geographically diverse states of India (Karnataka, Kerala, Punjab, Rajasthan). Data collected during home visits includes cognitive performance tests, and rich sociodemographic, health, and psychosocial variables. The cognitive performance tests include episodic memory, numeracy, and a modified version of the Mini-Mental State Examination. Results. We find gender disparity in cognitive function in India, and this disparity is greater in the north than the south. We also find that gender disparities in educational attainment, health, and social and economic activity explain the female cognitive disadvantage in later life. Discussion. We report significant gender disparities in cognitive functioning among older Indian adults, which differ from gender disparities in cognition encountered in developed countries. Our models controlling for education, health status, and social and economic activity explain the disparity in southern India but not the region-specific disparity in the northern India. North Indian women may face additional sources of stress associated with discrimination against women that contribute to persistent disadvantages in cognitive functioning at older ages.

    The effects of age and gender on electroencephalographic (EEG) activity during a short-term memory task were assessed in a group of 40 healthy participants aged 22-63 years. Multi-channel EEG was recorded in 20 younger (mean = 24.65-year-old, 10 male) and 20 middle-aged participants (mean = 46.40-year-old, 10 male) during performance of a Sternberg task. EEG power and coherence measures were analyzed in different frequency bands. Significant interactions emerged between age and gender in memory performance and concomitant EEG parameters, suggesting that the aging process differentially influences men and women. Middle-aged women showed a lower short-term memory performance compared to young women, which was accompanied by decreasing delta and theta power and increasing brain connectivity with age in women. In contrast, men showed no age-related decline in short-term memory performance and no changes in EEG parameters. These results provide first evidence of age-related alterations in EEG activity underlying memory processes, which were already evident in the middle years of life in women but not in men.

    Purpose/Objectives To determine the effect that age at diagnosis has on fear of breast cancer recurrence and to identify the predictors of fear of recurrence using self-efficacy as a mediator. Design Cross-sectional survey. Setting Two university cancer centers and one cooperative group in the midwestern United States. Sample 1,128 long-term survivors. Methods Survivors were eligible if they were aged 18–45 years (younger group) or 55–70 years (older group) at cancer diagnosis, had received chemotherapy, and were three to eight years postdiagnosis. Fear of recurrence was compared between younger and older groups. Multiple regression analyses were used to test variables’ prediction of fear of recurrence and breast cancer survivor self-efficacy, as well as breast cancer survivor self-efficacy mediation effects. Main Research Variables Fear of recurrence, breast cancer survivor self-efficacy, and age at diagnosis. Findings Survivors diagnosed at a younger age had significantly higher fear of recurrence, as well as health, role, womanhood, death, and parenting worries. Perceived risk of recurrence, trait anxiety, and breast cancer reminders explained significant variance in fear of recurrence and breast cancer survivor self-efficacy. Breast cancer survivor self-efficacy partially mediated the effects of variables on fear of recurrence. Conclusions The findings suggest that breast cancer survivor self-efficacy may have a protective effect for survivors who are younger at diagnosis and have higher perceived risk of recurrence, higher trait anxiety, and more breast cancer reminders. Oncology nurses already use the skills required to support self-efficacy. Additional research is needed to define and test breast cancer survivor self-efficacy interventions. Implications for Nursing Oncology nurses are in a key role to assess fear of recurrence and provide self-efficacy interventions to reduce it in breast cancer survivors.

    Reference values for standing lumbar curvature (SLC) obtained via noninvasive methods are not well established in persons without current low back pain. The effect of gender is considered to have a significant effect on SLC with women having more lumbar lordosis than men. The effect of age and degree of obesity are not considered to have a statistically significant effect on SLC. The purpose of this study was to test the assumption that measurements of SLC in healthy adults obtained by a flexible curve will differ between genders, whereas the SLC will not differ across categories of age and body mass index (BMI). Two hundred thirty-five volunteers (119 men and 116 women) whose ages ranged between 20 and 79 years participated in the study. Subjects were almost exclusively White and from the Midwest. Measurements of the SLC were obtained by a flexible curve. The curve's shape was transferred to poster board, and the value of SLC was quantified by a previously described technique. A three-way analysis of variance (alpha = 0.05) was used to examine the main effects of gender, age, and BMI on SLC. The effect of gender (F1,199 = 21.4, p < 0.0001) and the effect of age (F5,199 = 2.8, p < 0.017) were statistically significant. The effect of BMI (F2,199 = 1.8, p = 0.176) was not significant. Women (mean, 49.5 degrees +/-10.7 degrees ) demonstrated about 6.5 degrees more SLC than their male (mean, 43.0 degrees +/-10.7 degrees ) counterparts. For age, the only significant difference was between the 20 to 29- and 50 to 59-year-old age categories. This study provides physical therapists with typical values of SLC in men and women without current low back pain. PMID:17118891

This questionnaire covers three domains of eating behaviour ('cognitive restraint', 'disinhibition' and 'hunger') as well as common problems (e.g. craving for sweets). So far, there is a lack of normative data of the FEV especially for the middle-aged and older population. Aim of this study therefore was to provide age- and gender-specific norms of the FEV for the general population aged 40-79 years. We studied 3144 participants of the ongoing large community-based Leipzig Research Center for Civilization Diseases (LIFE) Health Care Study. We provided age- (four age groups: 40-49, 50-59, 60-69, and 70-79 years) and gender-specific percentile ranks and T-scores for the three domains of the FEV as well as age- and gender-specific frequencies of the common problems in eating behaviour. Females scored significantly higher than males in all three domains of the FEV (p < 0.001). Older individuals showed significantly higher mean scores than the younger ones in the domain of cognitive restraint, but lower mean scores in disinhibition and hunger (p < 0.001). 45.1% of the males and 69.9% of the females reported specific problems in eating. The main problem in both genders was craving for sweets (38.6%). Eating in response to stress was mostly reported in younger individuals. The present study offers current normative data for the FEV in the middle-aged and older general population that can be applied in clinical and non-clinical settings. Information on eating behaviour can be helpful in understanding body weight modulation, and thus, may help to improve interventive and preventive programmes for overweight, obesity, and eating disorders.

    Background Previous analyses reported age- and gender-related differences in the provision of cardiac care. The objective of the study was to compare circadian disparities in the delivery of primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) according to the patient’s age and gender. Methods We investigated patients included into the Acute Myocardial Infarction in Switzerland (AMIS) registry presenting to one of 11 centers in Switzerland providing primary PCI around the clock, and stratified patients according to gender and age. Findings A total of 4723 patients presented with AMI between 2005 and 2010; 1319 (28%) were women and 2172 (54%) were ≥65 years of age. More than 90% of patients <65 years of age underwent primary PCI without differences between gender. Elderly patients and particularly women were at increased risk of being withheld primary PCI (males adj. HR 4.91, 95% CI 3.93–6.13; females adj. HR 9.31, 95% CI 7.37–11.75) as compared to males <65 years of age. An increased risk of a delay in door-to-balloon time >90 minutes was found in elderly males (adj HR 1.66 (95% CI 1.40–1.95), p<0.001) and females (adj HR 1.57 (95% CI 1.27–1.93), p<0.001), as well as in females <65 years (adj HR 1.47 (95% CI 1.13–1.91), p = 0.004) as compared to males <65 years of age, with significant differences in circadian patterns during on- and off-duty hours. Conclusions In a cohort of patients with AMI in Switzerland, we observed discrimination of elderly patients and females in the circadian provision of primary PCI. PMID:26352574

    We surveyed 395 Korean middle-aged women and examined how their perceptions of family relationships, gender-role attitudes, and self-esteem were associated with Hwa-Byung (HB; Korean anger syndrome). Our regression analyses revealed that participants who reported worse family relationship problems experienced more HB symptoms. Having profeminist, egalitarian attitudes toward women's gender roles was also associated with more HB symptoms. Self-esteem was not significantly associated with HB. Based on the results, we suggest that what is crucial to understanding HB is not how women evaluate themselves, but rather the level of stress caused by family relationship problems and their perception of women's roles.

    Longing can be defined as a secondary emotion, as a blend of the primary emotions of love and sadness. There are several possible dimensions and aspects of longing (O. Holm, 1999). Both age and gender differences are well documented in earlier research on other emotions. In the present investigation, 122 girls and 120 boys, ages 9, 12, and 15 years, in compulsory school in Sweden, answered a questionnaire about dimensions and aspects of their own longing. The results showed both age and gender differences. Girls, especially in the 15-year-old group, experienced longing significantly more than boys. The results were interpreted as generally in accordance with what is known from earlier research on other emotions. PMID:11728061

    Marital status is a robust predictor of health outcomes in Western populations. However, data from Asian cultures remain sparse, and some studies suggest marked gender differences in the health benefits of marriage among Asian populations. We investigated the influence of marital status on depressive symptoms in older adult Koreans. Data were obtained from a sample of adults aged 45 to 85 years (4016 men, 5003 women) who participated in the 2006 cross-sectional baseline survey of the Korean Longitudinal Study of Ageing. Depressive symptoms were measured by the 10-item Center for Epidemiological Studies-Depression scale. A multiple regression model was used to examine the association between marital status and depressive symptoms, controlling for socioeconomic status, living arrangement, disability, and number of chronic diseases. In women aged 75 to 85 years, no significant differences were found between women who were married versus those who were widowed, divorced, or separated with regard to depressive symptoms. These findings were driven by increasing depressive symptoms among married women with age. Whereas divorced and widowed men in the sample reported higher rates of depressive symptoms than did married men, the difference between married vs. widowed/divorced women converged as they aged. This pattern of depressive symptoms by gender and life stage may reflect the distinctive influence of the Asian context on relations between men and women, such as traditional gender roles and patriarchal norms for older generation.

    Background In recent years, there was an increased interest in investigating the gender difference in performance and the age of peak performance in ultra-endurance performances such as ultra-triathlon, ultra-running, and ultra-swimming, but not in ultra-cycling. The aim of the present study was to analyze the gender difference in ultra-cycling performance and the age of peak ultra-cycling performance in the 720-km ‘Swiss Cycling Marathon’, the largest European qualifier for the ‘Race Across America’. Methods Changes in the cycling speed and age of 985 finishers including 38 women and 947 men competing in the Swiss Cycling Marathon from 2001 to 2012 covering a distance of 720 km with a change of altitude of 4,993 m were analyzed using linear regression. Results The gender difference in performance was 13.6% for the fastest cyclists ever, 13.9% ± 0.5% for the three fastest cyclists ever and 19.1% ± 3.7% for the ten fastest cyclists ever. The gender difference in performance for the annual top three women and men decreased from 35.0% ± 9.5% in 2001 to 20.4% ± 7.7% in 2012 (r2 = 0.72, p = 0.01). The annual top three women improved cycling speed from 20.3 ± 3.1 km h−1 in 2003 to 24.8 ± 2.4 km h−1 in 2012 (r2 = 0.79, p < 0.01). The cycling speed of the annual top three men remained unchanged at 30.2 ± 0.6 km h−1 (p > 0.05). The age of peak performance for the ten fastest finishers ever was 35.9 ± 9.6 years for men and 38.7 ± 7.8 years for women, respectively (p = 0.47). Conclusions The gender difference in ultra-cycling performance decreased over the 2001 to 2012 period in the 720-km Swiss Cycling Marathon for the annual top three cyclists and reached approximately 14%. Both women and men achieved peak performance at the age of approximately 36 to 39 years. Women might close the gender gap in ultra-endurance cycling in longer cycling distances. Future studies need to investigate the gender difference in performance in the Race Across America, the

    DSM-5 has lifted the age criterion in the definition of separation anxiety disorder thereby overturning the long-standing convention of restricting the diagnosis to childhood. Previously, adults with separation anxiety symptoms were assigned to other conventional categories such as panic disorder, agoraphobia or generalized anxiety disorder. Over the past two decades, an evolving body of research has identified separation anxiety disorder in adulthood, with 20-40% of adult psychiatric outpatients being assigned that diagnosis. In the US, the lifetime prevalence of the disorder in adulthood is 6.6%. The removal of the age restriction on diagnosis has important implications for clinical practice. Whereas parents (particularly mothers) of children with separation anxiety disorder commonly attracted the diagnosis of agoraphobia, the latter are more likely now to be diagnosed with the adult form of separation anxiety disorder, focusing attention on the importance of intervening with both members of the dyad to overcome mutual reinforcement of symptoms. In addition, adults with separation anxiety disorder have been found to manifest high levels of disability and they tend to show a poor response to conventional psychological and pharmacological treatments. There is an urgent need therefore to devise novel psychological and pharmacological interventions for the adult form of the disorder. The reformulation of separation anxiety disorder in DSM-5 therefore requires a paradigm shift in which clinicians are alerted to identifying and treating the condition in all age groups. Research across countries is needed to examine the new formulation of separation anxiety disorder amongst populations of diverse ethnic and cultural backgrounds. PMID:25453710

    According to the valence asymmetry hypothesis, the left/right asymmetry of PFC activity is correlated with specific emotional responses to mental stress and personality traits. In a previous study we measured spontaneous oscillation of oxy-Hb concentrations in the bilateral PFC at rest in normal adults employing two-channel portable NIRS and computed the laterality index at rest (LIR). We investigated the Pearson correlation coefficient between the LIR and anxiety levels evaluated by the State-Trait Anxiety Inventory (STAI) test. We found that subjects with right-dominant activity at rest showed higher STAI scores, while those with left dominant oxy-Hb changes at rest showed lower STAI scores such that the Pearson correlation coefficient between LIR and STAI was positive. This study performed Bootstrap analysis on the data and showed the following statistics of the target correlation coefficient: mean=0.4925 and lower confidence limit=0.177 with confidence level 0.05. Using the KS-test, we demonstrated that the correlation did not depend on age, whereas it did depend on gender. PMID:26782223

    We analyzed 700 million words, phrases, and topic instances collected from the Facebook messages of 75,000 volunteers, who also took standard personality tests, and found striking variations in language with personality, gender, and age. In our open-vocabulary technique, the data itself drives a comprehensive exploration of language that distinguishes people, finding connections that are not captured with traditional closed-vocabulary word-category analyses. Our analyses shed new light on psychosocial processes yielding results that are face valid (e.g., subjects living in high elevations talk about the mountains), tie in with other research (e.g., neurotic people disproportionately use the phrase ‘sick of’ and the word ‘depressed’), suggest new hypotheses (e.g., an active life implies emotional stability), and give detailed insights (males use the possessive ‘my’ when mentioning their ‘wife’ or ‘girlfriend’ more often than females use ‘my’ with ‘husband’ or 'boyfriend’). To date, this represents the largest study, by an order of magnitude, of language and personality. PMID:24086296

    Background: Numerous studies show higher cough reflex sensitivity (CRS) and cough outcomes in children compared to adults and in females compared to males. Despite close link that exists between cough and environment the potential influence of environmental air pollution on age- and gender -related differences in cough has not been studied yet. Purpose: The purpose of our study was to analyse whether the effects of exposure to environmental tobacco smoke (ETS) from parental smoking and PM10 from living in urban area are implied in age- and gender-related differences in cough outcomes of healthy, non-asthmatic children. Assessment of CRS using capsaicin and incidence of dry and wet cough was performed in 290 children (mean age 13.3 ± 2.6 years (138 females/152 males). Results: CRS was significantly higher in girls exposed to ETS [22.3 μmol/l (9.8–50.2 μmol/l)] compared to not exposed girls [79.9 μmol/l (56.4–112.2 μmol/l), p = 0.02] as well as compared to exposed boys [121.4 μmol/l (58.2–253.1 μmol/l), p = 0.01]. Incidence of dry cough lasting more than 3 weeks was significantly higher in exposed compared to not exposed girls. CRS was significantly higher in school-aged girls living in urban area [22.0 μmol/l (10.6–45.6 μmol/l)] compared to school-aged girls living in rural area [215.9 μmol/l (87.3–533.4 μmol/l); p = 0.003], as well as compared to teenage girls living in urban area [108.8 μmol/l (68.7–172.9 μmol/l); p = 0.007]. No CRS differences were found between urban and rural boys when controlled for age group. No CRS differences were found between school-aged and teenage boys when controlled for living area. Conclusions: Our results have shown that the effect of ETS on CRS was gender specific, linked to female gender and the effect of PM10 on CRS was both gender and age specific, related to female gender and school-age. We suggest that age and gender related differences in incidence of cough and CRS might be, at least partially

    2012-01-01

    Background General practitioners often care for patients with several concurrent chronic medical conditions (multimorbidity). Recent data suggest that multimorbidity might be observed more often than isolated diseases in primary care. We explored the age- and gender-related prevalence of multimorbidity and compared these estimates to the prevalence estimates of other common specific diseases found in Swiss primary care. Methods We analyzed data from the Swiss FIRE (Family Medicine ICPC Research using Electronic Medical Record) project database, representing a total of 509,656 primary care encounters in 98,152 adult patients between January 1, 2009 and July 31, 2011. For each encounter, medical problems were encoded using the second version of the International Classification of primary Care (ICPC-2). We defined chronic health conditions using 147 pre-specified ICPC-2 codes and defined multimorbidity as 1) two or more chronic health conditions from different ICPC-2 rubrics, 2) two or more chronic health conditions from different ICPC-2 chapters, and 3) two or more medical specialties involved in patient care. We compared the prevalence estimates of multimorbidity defined by the three methodologies with the prevalence estimates of common diseases encountered in primary care. Results Overall, the prevalence estimates of multimorbidity were similar for the three different definitions (15% [95%CI 11-18%], 13% [95%CI 10-16%], and 14% [95%CI 11-17%], respectively), and were higher than the prevalence estimates of any specific chronic health condition (hypertension, uncomplicated 9% [95%CI 7-11%], back syndrome with and without radiating pain 6% [95%CI 5-7%], non-insulin dependent diabetes mellitus 3% [95%CI 3-4%]), and degenerative joint disease 3% [95%CI 2%-4%]). The prevalence estimates of multimorbidity rose more than 20-fold with age, from 2% (95%CI 1-2%) in those aged 20–29 years, to 38% (95%CI 31-44%) in those aged 80 or more years.

    Ozone (O3) is a respiratory irritant that leads to airway inflammation and pulmonary dysfunction. Animal studies show that neonates are more sensitive to O3 inhalation than adults, and children represent a potentially susceptible population. This latter notion is not well established, and biological mechanisms underlying a predisposition to pollution-induced pulmonary effects are unknown. We examined age and strain as interactive factors affecting differential pulmonary responses to inhaled O3. Male and female adult mice (15 weeks old) and neonates (15–16 days old) from eight genetically diverse inbred strains were exposed to 0.8 ppm O3 for 5 h. Pulmonary injury and lung inflammation were quantified as total protein concentration and total polymorphonuclear neutrophil (PMN) number in lavage fluid recovered 24-h postexposure. Dose-response and time-course curves were generated using SJL/J pups, and 18O lung burden dose was assessed in additional mice. Interstrain differences in response to O3 were seen in neonatal mice: Balb/cJ and SJL/J being most sensitive and A/J and 129x1/SvJ most resistant. The PMN response to O3 was greater in neonates than in adults, specifically for SJL/J and C3H/HeJ strains, independent of dose. Small gender differences were also observed in adult mice. Variation in protein concentrations and PMN counts between adults and pups were strain dependent, suggesting that genetic determinants do play a role in age-related sensitivity to O3. Further research will help to determine what genetic factors contribute to these heightened responses, and to quantify the relative contribution of genes vs. environment in O3-induced health effects.

    Objectives To study the characteristics of cardiovascular risk factors in regard to age (before and after 60) and gender. Many reports refer to the higher prevalence of cardiovascular risk factors among the younger type 2 diabetics in comparison with the older population. Methods The study included 462 randomly recruited type 2 diabetic subjects (above and below 60 years) attending Al-Zahrawi Private Hospital in Mosul City-Iraq, during the period from June to August 2011. They were analyzed in regard to age, duration of diabetes, smoking, socioeconomic status, anthropometric indices, blood pressure, fasting plasma glucose, glycated hemoglobin A1c and serum lipids. Data were analyzed using chi-square and unpaired Z test. Results Duration of diabetes, diastolic blood pressure, glycated hemoglobin A1c, fasting plasma glucose, serum lipids, number of hypercholesterolemic patients, number of patients having unfavorable total cholesterol/HDL ratio (≥5) and positive family history of coronary heart disease were all significantly higher in the younger diabetics. In addition, younger diabetic females were distinguished by a larger number of hypertensive patients, higher level of systolic blood pressure, higher means of body mass index, total cholesterol and LDL, and larger number of patients having low HDL-C (<1 mmol/L). The younger diabetic males were distinct by a larger number of smokers, number of smoked cigarettes/day, and longer duration of smoking. All parameters ranged between p<0.05 and p<0.005. Conclusion Cardiovascular risk factors were significantly higher among younger type 2 diabetics (<60 years), particularly females. PMID:23074547

    This study explored preschool age and gender differences in help-seeking within the theoretical framework of scaffolded problem-solving and self-regulation (Bruner, 1986; Rogoff, 1990; Vygotsky, 1978; 1986). Within-subject analyses tracked changes in help-seeking among 62 preschoolers (34 boys, 28 girls, mean age 4.22 years) solving a challenging puzzle with an adult. The goal was to document whether age and gender interact with fluctuating difficulty to affect children's spontaneous help-seeking. ANOVAs indicated that girls used more help-seeking during difficult segments of the task, despite performance equal to the boys. This pattern was strongest among older girls, who outperformed all other children and used the most help-seeking. Partial correlations, controlling for solving time, indicated that age predicted children's help-seeking during the most difficult segments of the task, but only among girls. Gender differences in social-linguistic maturation and cognitive development are discussed within the framework of Vygotskian theory and related educational practice. PMID:22217160

    Background. Dyslipidemia contribute to the excess of coronary heart disease (CHD) risk observed in women with type 2 diabetes (T2DM). Low density lipoprotein-cholesterol (LDL-C) is the major target for CHD prevention, and T2DM women seem to reach LDL-C targets less frequently than men. Aim. To explore age- and gender-related differences in LDL-C management in a large sample of outpatients with T2DM. Results. Overall, 415.294 patients (45.3% women) from 236 diabetes centers in Italy were included. Women were older and more obese, with longer diabetes duration, higher total-cholesterol, LDL-C, and HDL-C serum levels compared to men (P < 0.0001). Lipid profile was monitored in ~75% of subjects, women being monitored less frequently than men, irrespective of age. More women did not reach the LDL-C target as compared to men, particularly in the subgroup treated with lipid-lowering medications. The between-genders gap in reaching LDL-C targets increased with age and diabetes duration, favouring men in all groups. Conclusions. LDL-C management is worst in women with T2DM, who are monitored and reach targets less frequently than T2DM men. Similarly to men, they do not receive medications despite high LDL-C. These gender discrepancies increase with age and diabetes duration, exposing older women to higher CHD risk. PMID:25873960

    Stressful life events have been associated with child and adolescent maladjustment, including elevated levels of aggression and anxiety (Attar et al. in J Clin Child Psychol 23:391-400, 1994; Fox et al. in J Adolesc 33:43-54, 2010). However, gender specific outcomes associated with stressful life events among elementary school-age youth are less known. Accordingly, the current study examined the role of gender in the associations between stressful life events and anxiety and proactive and reactive aggression. Participants included 294 elementary school-age children (M = 8.71, SD = 1.17, 50.7 % male). Regression analyses indicated that stressful life events were positively associated with anxiety and reactive, but not proactive, aggression. There were no gender differences with regard to the associations with anxiety symptoms or proactive aggression. However, gender moderated the association between stressful life events and reactive aggression, such that stressful life events were only positively associated with reactive aggression for boys. Future directions and implications of this research are presented. PMID:26429570

    The purpose of this study was to examine the dimensional structure and measurement invariance of Bryant's Index of Empathy for Children and Adolescents (IECA) (Bryant, 1982) across gender in a representative sample of primary school-aged children in Spain. The sample consisted of 2,050 children (50.80% girls), with a mean age of 9.80 years (SD = 1.24), recruited from 27 primary schools. Exploratory and confirmatory factor analyses were conducted. The model that presented the best fit indices was Lasa, Holgado, Carrasco, and del Barrio's (2008) three-factor model: Understanding Feelings, Feelings of Sadness, and Tearful Reaction. The levels of internal consistency for the subscales ranged from .76 to .83. In addition, the results partially support the measurement invariance of the IECA across gender. When the latent means of the empathy dimensions were compared across gender, statistically significant differences were found. These results coincide with those found in the literature showing the multidimensionality of the IECA. Specifically, the findings support its three-factor structure and its invariance across gender, making it a very useful instrument for exploring the expression of empathy in primary school children.

  9. Age and gender differences in disabling foot pain using different definitions of the manchester foot pain and disability index

    PubMed Central

    2011-01-01

    Background The Manchester Foot Pain and Disability Index (MFPDI) has been used to determine the prevalence of disabling foot pain in several studies, however there is some debate as to which case definition is most appropriate. The objective of this study was to explore age and gender differences in the proportion of people with disabling foot pain using three different case definitions of the MFPDI and for each individual MFPDI item. Methods A random sample of 223 participants aged 27 to 90 years (88 males and 135 females) from the North West Adelaide Health Study, who reported having pain, aching or stiffness in either of their feet on most days in the last month, completed the MFPDI by telephone interview. The proportion of people with disabling foot pain was determined using three definitions: (i) Definition A-at least one of the 17 items documented on at least some days in the last month; (ii) Definition B-at least one of the 17 items documented on most/every day(s) in the last month, and; (iii) Definition C-at least one of the ten functional limitation items documented on most/every day(s) in the last month. Cross-tabulations and chi-squared statistics were used to explore differences in responses to the MFPDI items according to age and gender. Results The proportion of people with disabling foot pain according to each definition was as follows: Definition A (100%), Definition B (95.1%) and Definition C (77.6%). Definition C was most sensitive to age and gender differences. Exploration of individual MFPDI items indicated that age significantly affected both the pain intensity and functional limitation items, with younger people more likely to report their foot pain being worse in the morning, and older people more likely to report functional limitations. Although gender did not influence responses to the personal appearance items, women were more likely report functional limitations than men. Conclusions Definition C of the MFPDI is more sensitive to age and

    Background The effects of age, body mass index (BMI) and gender on motor vehicle crash (MVC) injuries are not well understood and current prevention efforts do not effectively address variability in occupant characteristics. Objectives 1) Characterize the effects of age, BMI and gender on serious-to-fatal MVC injury 2) Identify the crash modes and body regions where the effects of occupant characteristics onthe numbers of occupants with injuryis largest, and thereby aid in prioritizing the need forhuman surrogates that the represent different types of occupant characteristics and adaptive restraint systems that consider these characteristics. Methods Multivariate logistic regression was used to model the effects of occupant characteristics (age, BMI, gender), vehicle and crash characteristics on serious-to-fatal injuries (AIS 3+) by body region and crash mode using the 2000-2010 National Automotive Sampling System (NASS-CDS) dataset. Logistic regression models were applied to weighted crash data to estimate the change in the number of annual injured occupants with AIS 3+ injury that would occur if occupant characteristics were limited to their 5th percentiles (age ≤ 17 years old, BMI ≤ 19 kg/m2) or male gender. Results Limiting age was associated with a decrease inthe total number of occupants with head [8,396, 95% CI 6,871-9,070] and thorax injuries [17,961, 95% CI 15,960 – 18,859] across all crash modes, decreased occupants with spine [3,843, 95% CI 3,065 – 4,242] and upper extremity [3,578, 95% CI 1,402 – 4,439] injuries in frontal and rollover crashes and decreased abdominal [1,368, 95% CI 1,062 – 1,417] and lower extremity [4,584, 95% CI 4,012 – 4,995] injuries in frontal impacts. The age effect was modulated by gender with older females morelikely to have thorax and upper extremity injuries than older males. Limiting BMI was associated with 2,069 [95% CI 1,107 – 2,775] fewer thorax injuries in nearside crashes, and 5,304 [95% CI 4,279 – 5

  11. Compulsive buying--a growing concern? An examination of gender, age, and endorsement of materialistic values as predictors.

    PubMed

    Dittmar, Helga

    2005-11-01

    Compulsive buying is an understudied, but growing, dysfunctional consumer behaviour with harmful psychological and financial consequences. Clinical perspectives treat it as a psychiatric disorder, whereas recent proposals emphasize the increasing endorsement of materialistic values as a cause of uncontrolled buying (e.g. Dittmar, 2004b; Kasser & Kanner, 2004). The present research aims to improve understanding of compulsive buying through examining gender, age, and endorsement of materialistic values as key predictors in three UK questionnaire studies, which sampled individuals who had contacted a self-help organization and residentially matched 'controls' (N = 330), consumer panelists from a multinational corporation (N = 250), and 16- to 18-year-old adolescents (N = 195). The results confirmed previously documented gender differences, and showed that younger people are more prone to compulsive buying. The central findings were that materialistic value endorsement emerged as the strongest predictor of individuals' compulsive buying, and that it significantly mediated the observed age differences.

    Aim: The aim was to develop a high-performance computer-aided diagnosis (CAD) system with image processing and pattern recognition in diagnosing pancreatic cancer by using endosonography images. Materials and Methods: On the images, regions of interest (ROI) of three groups of patients (<40, 40-60 and >60) were extracted by experts; features were obtained from images using three different techniques and were trained separately for each age group with an Artificial Neural Network (ANN) to diagnose cancer. The study was conducted on endosonography images of 202 patients with pancreatic cancer and 130 noncancer patients. Results: 122 features were identified from the 332 endosonography images obtained in the study, and the 20 most appropriate features were selected by using the relief method. Images classified under three age groups (in years; <40, 40-60 and >60) were tested via 200 random tests and the following ratios were obtained in the classification: accuracy: 92%, 88.5%, and 91.7%, respectively; sensitivity: 87.5%, 85.7%, and 93.3%, respectively; and specificity: 94.1%, 91.7%, and 88.9%, respectively. When all the age groups were assessed together, the following values were obtained: accuracy: 87.5%, sensitivity: 83.3%, and specificity: 93.3%. Conclusions: It was observed that the CAD system developed in the study performed better in diagnosing pancreatic cancer images based on classification by patient age compared to diagnosis without classification. Therefore, it is imperative to take patient age into consideration to ensure higher performance. PMID:27080608

    2011-01-01

    Background. Age-specific incidence rates for breast cancer in low-risk and high-risk ethnic populations differ by age at which the incidence maximum is reached: around 50 years in low-risk populations and over 60 years in high-risk populations. The interpretation of these differences remains unsettled, one line primarily referring to biological differences, the second one to cohort effects of rapidly increasing rates in young populations, and the third one to incomplete registration of cancer in the elderly. Methods. The nationwide Family-Cancer Database was used to analyze standardized incidence ratios (SIRs) and age at diagnosis of breast cancer in female immigrants to Sweden by their region of origin compared with women native to Sweden matched on birth year and other relevant factors. Results. We showed first that the SIRs for breast cancer were lower in many immigrant groups compared with natives of Sweden; women from Turkey had the lowest SIR of 0.45, followed by those from Chile (0.54) and Southeast Asia (0.57). Women from nine regions showed an earlier mean age at diagnosis than their matched Swedish controls, the largest differences being 5.5 years for women from Turkey, 5.1 years for those from Asian Arab and “Other African” countries, 4.3 years for those from Iran, and 4.0 years for those from Iraq. Conclusions. The results show that in many immigrant groups, the diagnostic age is earlier (<50 years) than in natives of Sweden (>50 years), suggesting that true biological factors underlie the differences. These factors may explain much of the international variation in breast cancer incidence. Identifying these factors should advance understanding of breast cancer etiology and prevention.

    The aim of the present study was to evaluate accuracy of transabdominal ultrasonography for pregnancy diagnosis, determination of fetal number and estimation of gestational age in ewes. A total of 1068 ewes from 8 different flocks (Swiss White Alpine n = 379, Swiss Black-Brown Mountain n = 189, Oxford-type n = 164, Ostfriesian n = 154, Texel n = 104, Lacaune x Osfriesian crossbred n = 78) was investigated using an Ovi-Scan™ ultrasound scanner with a 3.5 MHz 170° mechanical axial probe (BCF Technology Ltd., BelIshill, Great Britain). Scanning was performed transabdominally at the right inguinal region in ewes restrained in standing position. Sonographic findings were compared with lambing data recorded by the farmers. Included in the analysis were all ewes that, at the time of examination, were not pregnant and those that were pregnant between 26 and 110 days with a known lambing date and number of lambs born (n = 882). The sensitivity of pregnancy diagnosis was 97.8% and the specificity 97.6% (overall accuracy 97.8%, n = 853). Sensitivity and specificity for discrimination between single and multiple pregnancies was 95.8% and 90.5% (overall accuracy 93.9%, n = 752), respectively, when multiples were defined as positive. Discrimination between twins and triplets reached a sensitivity of 86.0% and a specificity of 99.5% (overall accuracy 98.0%, n = 458) when triplets were defined as positive. Considering a gestation period of 150 days, the mean deviation of the estimated to the effective day of gestation at examination was 5.6 ± 5.0 days (n = 781). The correlation between estimated and true gestational age was very high (r=0.936, P<0.0001). In conclusion, a highly accurate and efficient diagnosis of pregnancy with reliable estimation of fetal number and age is possible using an Ovi-Scan™ ultrasound scanner by an experienced examiner.

    Femoroacetabular impingement (FAI) syndrome is a frequent cause of pain and in recent years considered to be a precursor of premature hip osteoarthritis. The structural abnormalities which characterize FAI syndrome, such as the cam-type deformity, are associated with morphological alterations that may lead to hip osteoarthritis. The aim of this study was to determine the prevalence and topographic and morphometric features of the cam deformity in a series of 326 femur specimens obtained from a Mexican population, as well as changes in prevalence in relation to age and gender. The specimens were subdivided into groups according to gender and age. A standardized photograph of the proximal femur of each specimen was taken, and the photograph was used to determine the alpha angle using a computer program; the location of the lesion was determined by quadrant and the morphometric characteristics were determined by direct observation. The overall prevalence of cam deformities in the femur specimens was 29.8 % (97/326), with a prevalence by gender of 35.2 % (64/182) in men and 22.9 % (33/144) in women. The mean alpha angle was 54.6° ± 8.5° in all of the osteological specimens and 65.6° ± 7.5° in those specimens exhibiting a cam deformity. Cam deformities were found topographically in the anterior-superior quadrant of the femoral head-neck junction in 86.6 % (84/97) of the femurs. Deformities were found in 28.2 % of the right femurs and 31.3 % of the left femurs. The prevalence of cam deformity was higher in the femur specimens of young men and in those of middle-aged and older women. There were no significant differences in this deformity in relation to the alpha angle according to age and gender. PMID:26573638

    Alterations in DNA methylation have been proposed to create a field cancerization state in the colon, where molecular alterations that predispose cells to transformation occur in histologically normal tissue. However, our understanding of the role of DNA methylation in field cancerization is limited by an incomplete characterization of the methylation state of the normal colon. In order to determine the colon’s normal methylation state, we extracted DNA from normal colon biopsies from the rectum, sigmoid, transverse, and ascending colon and assessed the methylation status of the DNA by pyrosequencing candidate loci as well as with HumanMethylation450 arrays. We found that methylation levels of repetitive elements LINE-1 and SAT-α showed minimal variability throughout the colon in contrast to other loci. Promoter methylation of EVL was highest in the rectum and progressively lower in the proximal segments, whereas ESR1 methylation was higher in older individuals. Genome-wide methylation analysis of normal DNA revealed 8388, 82, and 93 differentially methylated loci that distinguished right from left colon, males from females, and older vs. younger individuals, respectively. Although variability in methylation between biopsies and among different colon segments was minimal for repetitive elements, analyses of specific cancer-related genes as well as a genome-wide methylation analysis demonstrated differential methylation based on colon location, individual age, and gender. These studies advance our knowledge regarding the variation of DNA methylation in the normal colon, a prerequisite for future studies aimed at understanding methylation differences indicative of a colon field effect.

    In the same way that many aspects of gender cannot be understood aside from their relationship to race, class, culture, nationality and/or sexuality, the interactions between gender and aging constitute an interesting field for academic research, without which we cannot gain full insight into the complex and multi-faceted nature of gender studies. Although the American writer and Columbia professor Carolyn Gold Heilbrun (1926-2003) is more widely known for her best-selling mystery novels, published under the pseudonym of Amanda Cross, she also authored remarkable pieces of non-fiction in which she asserted her long-standing commitment to feminism, while she also challenged established notions on women and aging and advocated for a reassessment of those negative views. To my mind, the Kate Fansler novels became an instrument to reach a massive audience of female readers who might not have read her non-fiction, but who were perhaps finding it difficult to reach fulfillment as women under patriarchy, especially upon reaching middle age. Taking her essays in feminism and literary criticism as a basis and her later fiction as substantiation to my argument, this paper will try to reveal the ways in which Heilbrun's seemingly more superficial and much more commercial mystery novels as Amanda Cross were used a catalyst that informed her feminist principles while vindicating the need to rethink about issues concerning literary representations of mature women and cultural stereotypes about motherhood.

    Non-motor symptoms in Parkinson's disease (PD) have been often described at different stages of the disease but they are poorly understood. We observed specific phenotypes related to these symptoms in mice lacking the PD-associated GPR37/PAEL receptor. GPR37 is an orphan G-protein-coupled receptor highly expressed in the mammalian central nervous system. It is a substrate of parkin and it is involved in the pathogenesis of PD. GPR37 interacts with the dopamine transporter (DAT), modulating nigro-striatal dopaminergic signaling and behavioral responses to amphetamine and cocaine. GPR37 knockout (KO) mice are resistant to MPTP and exhibit several motor behavioral abnormalities related to altered dopaminergic system function. To evaluate non-motor behavioral domains, adult and aged, male and female GPR37 KO mice and their wild-type (WT) littermates were analyzed in a series of cross-sectional studies. Aged GPR37 KO female mice showed mild improvements in olfactory function, while anxiety and depression-like behaviors appeared to be significantly increased. A reduction of the startle response to acoustic stimuli was observed only in adult GPR37 KO mice of both genders. Furthermore, HPLC analysis of major neurotransmitter levels revealed gender differences in the striatum, hippocampus and olfactory bulb of mutant mice. The absence of GPR37 receptor could have a neuroprotective effect in an age and gender-dependent manner, and the study of this receptor could be valuable in the search for novel therapeutic targets.

    Background: To analyse time trends in self-rated health in older people by gender and age and examine disability in the time trends of self-rated health. Methods: The data used come from the Spanish National Health Surveys conducted in 2001, 2003, 2006 and 2011–12. Samples of adults aged 16 yr and older were selected. Multivariate logistic regression was used to assess the association between age, gender, socio-economic status, marital status, disability and self-rated health across period study. Results: Women exhibited lower (higher) prevalence of good self-rated health (disability) compared to men. The multivariate analysis for time trends found that good self-rated health increased from 2001 to 2012. Overall, variables associated with a lower likelihood of good self-rated health were: being married or living with a partner, lower educational level, and disability. Conclusion: Trends of good self-rated health differ by gender according to socio-demographic factors and the prevalence of disability. PMID:27141490

    Objective. This study aimed to investigate the impact of subject age, gender, and arch length on dentists' attitudes towards unrestored shortened dental arches. Materials and Methods. 93 Syrian dentists were interviewed and presented with 24 scenarios for male and female subjects of different ages and shortened dental arches of varying length. Participants were asked to indicate on a standardized visual analogue scale how they would value the health of the mouth if the posterior space was left unrestored. Results. A value of 0.0 represented the worst possible health state for a mouth and 1.0 represented the best. The highest mean value (0.73) was assigned to a shortened dental arch with missing second molar teeth in the mouth of a 70-year-old subject. A 35-year-old female subject with an extremely shortened dental arch (all molar and premolar teeth are missing) attracted the lowest mean value (0.26). The statistical analysis indicated a significant decrease in the value placed on unrestored shortened dental arches as the number of remaining teeth decreased (p < 0.008). While subject gender had almost no impact on dentists' attitudes towards shortened dental arches, the scenarios for the older shortened dental arch subjects attracted significantly higher values compared to the scenarios for the younger subjects (p < 0.017). Conclusion. Subject age and arch length affect dentists' attitudes towards shortened dental arches, but subject gender does not. PMID:26265916

    Objective: The main objective of the study was morphometric evaluation of the frontal sinus in relation to age and gender and to establish its forensic importance and application. Materials and Method: The study group consisted of 200 subjects (100 males and 100 females) in the age groups 14-20 years, 21-30 years, 31-45 years, 45 years and above. Posteroanterior (PA) cephalogram radiographs were taken using standardized technique. The processed films were traced and frontal sinus pattern was established as per Yoshino's classification system. Results: The mean values for length, width, and area of the frontal sinus were found to be higher in males as compared to females and area of frontal sinuses increase with age except in males who were 45 years and above. The left width, left area, and bilateral asymmetry in relation to gender was found to be statistically significant. Conclusion: The morphologic evaluation of frontal sinus is a useful technique to determine gender and seems promising in personal identification. PMID:27051227

    Background Total sedentary time varies across population groups with important health consequences. Patterns of sedentary time accumulation may vary and have differential health risks. The purpose of this study is to describe sedentary patterns of older adults living in retirement communities and illustrate gender and age differences in those patterns. Methods Baseline accelerometer data from 307 men and women (mean age = 84±6 years) who wore ActiGraph GT3X+ accelerometers for ≥ 4 days as part of a physical activity intervention were classified into bouts of sedentary time (<100 counts per minute). Linear mixed models were used to account for intra-person and site-level clustering. Daily and hourly summaries were examined in mutually non-exclusive bouts of sedentary time that were 1+, 5+, 10+, 20+, 30+, 40+, 50+, 60+, 90+ and 120+ minutes in duration. Variations by time of day, age and gender were explored. Results Men accumulated more sedentary time than women in 1+, 5+, 10+, 20+, 30+, 40+, 50+ and 60+ minute bouts; the largest gender-differences were observed in 10+ and 20+ minute bouts. Age was positively associated with sedentary time, but only in bouts of 10+, 20+, 30+, and 40+ minutes. Women had more daily 1+ minute sedentary bouts than men (71.8 vs. 65.2), indicating they break up sedentary time more often. For men and women, a greater proportion of time was spent being sedentary during later hours of the day than earlier. Gender differences in intra-day sedentary time were observed during morning hours with women accumulating less sedentary time overall and having more 1+ minute bouts. Conclusions Patterns identified using bouts of sedentary time revealed gender and age differences in the way in which sedentary time was accumulated by older adults in retirement communities. Awareness of these patterns can help interventionists better target sedentary time and may aid in the identification of health risks associated with sedentary behavior. Future studies

    Background Bone formation marker procollagen I N-terminal peptide (PINP) and resorption marker C-terminal telopeptide of type I collagen (β-CTX) are useful biomarkers for differential diagnosis and therapeutic evaluation of osteoporosis, but reference values are required. Methods The multi-center, cross-sectional Chinese Bone Turnover Marker Study included 3800 healthy volunteers in 5 Chinese cities. Serum PINP, β-CTX, parathyroid hormone (PTH) and 25OHD levels were measured by chemiluminescence assay. Lumbar spine and proximal femur BMD were measured by dual-energy X-ray absorptiometry. Serum PINP and β-CTX levels were assessed by age, gender, weight, recruitment latitude, levels of PTH and 25OHD. Results Subjects (n = 1436, M∶F, 500∶936; mean age 50.6±19.6 years) exhibited non-normally distributed PINP and β-CTX peaking between 15–19 years, gradually declining throughout adulthood, elevating within 10 years of postmenopause, and then declining by age 70. In women between the age of 30 and menopause, median PINP and β-CTX levels were 40.42 (95% CI: 17.10–102.15) and 0.26 (95% CI: 0.08–0.72) ng/mL, respectively. β-CTX and PINP were positively linearly correlated (r = 0.599, P<0.001). β-CTX correlated positively (r = 0.054 and 0.093) and PINP correlated negatively (r = −0.012 and −0.053) with 25OHD and PTH (P<0.05). Conclusions We established Chinese reference ranges for PINP and CTX. Chinese individuals exhibited high serum PINP and β-CTX levels between 15 and 19 years of age and at menopause, which gradually declined after 70 years of age. PMID:25117452

Subjects and Methods Subjects were part of the CALEX-family study and comprised 235 young women, 121 premenopausal women, 124 postmenopausal women, and 168 men. Body composition was assessed using DXA, as was areal bone mineral density (aBMD) of spine, femur and whole body. In addition, pQCT was used to determine bone properties at tibial midshaft and distal radius. Fasting serum serotonin concentration was assessed using a competitive enzyme-linked immunosorbent assay. Results Serum serotonin declined with advancing age both in females and males (all p<0.01). Serotonin was negatively correlated with weight, BMI, lean and fat mass in women (r = −0.22 to −0.39, all p<0.001), but positively with height and lean mass in men (all p<0.01). In the premenopausal women, serotonin was negatively correlated with lumbar spine aBMD (r = −0.23, p<0.05) but the statistical significance disappeared after adjustment for weight. Conversely, in postmenopausal women, serotonin was positively correlated with whole body and femur aBMD, as well as with distal radius bone mineral content and volumetric BMD (r = 0.20 to 0.30, all p<0.05), and these associations remained significant after adjustment for weight. In men, no significant associations were found between serotonin and bone traits. Conclusion Serum serotonin is positively associated with bone traits in postmenopausal women, but not in premenopausal women or men. This partially supports the idea of circulating serotonin playing a role in the regulation of bone metabolism, but also indicates the importance of gender and age specific factors. PMID:25279460

  6. Circulating Cathelicidin Concentrations in a Cohort of Healthy Children: Influence of Age, Body Composition, Gender and Vitamin D Status

    PubMed Central

    2016-01-01

    Cathelicidin is an antimicrobial peptide whose circulating levels are related to vitamin D status in adults. This study sought to determine if circulating cathelicidin concentrations in healthy children are related to the age of the child, body composition and vitamin D status at birth and at the time of the study visit. Blood samples were obtained during yearly visits from 133 children, ages 2–7, whose mothers had participated in a pregnancy vitamin D supplementation RCT. Radioimmunoassay and ELISA were performed to analyze 25(OH)D and cathelicidin, respectively. Statistical analyses compared cathelicidin concentrations with concentrations of 25(OH)D at various time points (maternal levels throughout pregnancy, at birth, and child’s current level); and with race/ethnicity, age, gender, BMI, percent fat, and frequency of infections using Student’s t-test, χ2, Wilcoxon ranked-sum analysis, and multivariate regression. The cohort’s median cathelicidin concentration was 28.1 ng/mL (range: 5.6–3368.6) and did not correlate with 25(OH)D, but was positively correlated with advancing age (ρ = 0.236 & p = 0.005, respectively). Forty patients evaluated at two visits showed an increase of 24.0 ng/mL in cathelicidin from the first visit to the next (p<0.0001). Increased age and male gender were correlated with increased cathelicidin when controlling for race/ethnicity, percent fat, and child’s current 25(OH)D concentration (p = 0.028 & p = 0.047, respectively). This study demonstrated that as children age, the concentration of cathelicidin increases. Furthermore, male gender was significantly associated with increased cathelicidin concentrations. The lack of association between vitamin D status and cathelicidin in this study may be due to the narrow range in observed 25(OH)D values and warrants additional studies for further observation.

    Muscle mass is particularly relevant to follow during aging, owing to its link with physical performance and autonomy. The objectives of this work were to assess muscle volume (MV) and intramuscular fat (IMF) for all the muscles of the thigh in a large population of young and elderly healthy individuals using magnetic resonance imaging (MRI) to test the effect of gender and age on MV and IMF and to determine the best representative slice for the estimation of MV and IMF. The study enrolled 105 healthy young (range 20-30 years) and older (range 70-80 years) subjects. MRI scans were acquired along the femur length using a three-dimension three-point Dixon proton density-weighted gradient echo sequence. MV and IMF were estimated from all the slices. The effects of age and gender on MV and IMF were assessed. Predictive equations for MV and IMF were established using a single slice at various femur levels for each muscle in order to reduce the analysis process. MV was decreased with aging in both genders, particularly in the quadriceps femoris. IMF was largely increased with aging in men and, to a lesser extent, in women. Percentages of MV decrease and IMF increase with aging varied according to the muscle. Predictive equations to predict MV and IMF from single slices are provided and were validated. This study is the first one to provide muscle volume and intramuscular fat infiltration in all the muscles of the thigh in a large population of young and elderly healthy subjects. PMID:26040416

    Objective: We report on the incidence and the gender, age and ethnic distribution of sarcomas diagnosed between 1980 and 2008 in the multi-ethnic Republic of Suriname. Methods: Total and average yearly number of cases, crude rates, as well as relevant population data were derived from the records of the Pathologic Anatomy Laboratory and the General Bureau of Statistics, respectively, and stratified according to gender, age groups 0–19, 20–49 and 50+ years, and the largest ethnic groups (Hindustani, Creole, Javanese and Maroons). Results: Between 1980 and 2008, 258 sarcomas were diagnosed in Suriname, ie at a frequency of nine per year and an annual rate of two per 100 000. Overall, there was 0.9 male per female, two to four cases per year in each age group, and one to three patients in each ethnic group. Soft-tissue sarcomas comprised approximately 80% of overall cases, with a male/female ratio that was approximately 0.5; almost 90% of patients were older than 20 years; more than one-third was Creole. Leiomyosarcoma, fibrosarcoma and liposarcoma were most frequently encountered (90 cases), particularly above 20 years of age, while leiomyosarcomas seemed, additionally, more common in women and Creoles or Maroons. The most numerous bone tumours were primitive neuroectodermal tumour/Ewing tumour and osteosarcoma (37 cases). They were more common in males, the youngest age group, and Hindustanis and Creoles. Conclusions: The incidence of sarcomas in Suriname, and their gender, age and ethnic distribution in general, seemed comparable with international data. The main exception might be leiomyosarcoma which might have a predilection for Afro-Surinamese. PMID:25303244

    Gender dysphoria (GD), a term that denotes persistent discomfort with one's biologic sex or assigned gender, replaced the diagnosis of gender identity disorder in the Diagnostic and Statistical Manual of Mental Disorders in 2013. Subtypes of GD in adults, defined by sexual orientation and age of onset, have been described; these display different developmental trajectories and prognoses. Prevalence studies conclude that fewer than 1 in 10,000 adult natal males and 1 in 30,000 adult natal females experience GD, but such estimates vary widely. GD in adults is associated with an elevated prevalence of comorbid psychopathology, especially mood disorders, anxiety disorders, and suicidality. Causal mechanisms in GD are incompletely understood, but genetic, neurodevelopmental, and psychosocial factors probably all contribute. Treatment of GD in adults, although largely standardized, is likely to evolve in response to the increasing diversity of persons seeking treatment, demands for greater client autonomy, and improved understanding of the benefits and limitations of current treatment modalities.

    Psychological stress due to social isolation is known to cause abnormal feeding behaviors, but the influences of gender and aging on subchronic stress-induced changes in feeding behaviors are unknown. Thus, we examined the changes in body weight, food intake, and orexigenic ghrelin-related factors during 2 weeks of isolation stress in young and aged mice. Food intake increased significantly in young mice in the isolation group compared with the group-housed control throughout the experimental period. This isolation-induced increase in food intake was not observed in aged mice. In young mice, there were no significant differences in body weight between the isolated group and group-housed control up to 2 weeks. However, aged male mice exhibited significant weight loss at 2 weeks and a similar tendency was observed in aged female mice. Young male mice, but not female mice, had significantly increased (2.2-fold) plasma acylated ghrelin levels after 1 week of isolation compared with the group-housed control. A significant but lower increase (1.3-fold) was also observed in aged male mice. Hypothalamic preproghrelin gene expression decreased significantly with isolation in young male mice, whereas it increased significantly in female mice. The expression levels of NPY and AGRP in the hypothalamus, which are transmitted by elevated peripheral ghrelin signals, increased significantly in isolated young male mice, whereas the AGRP expression levels decreased significantly in young female mice. Isolation caused no significant differences in the expression levels of these genes in aged mice. In isolation, young female mice exhibited markedly increased dark- and light-phase locomotor activities compared with male mice, whereas male and female aged mice exhibited no obvious increases in activity immediately after the dark phase started. We conclude that the gender-specific homeostatic regulatory mechanisms required to maintain body weight operated during subchronic psychological

    This study examined the associations between children's and adolescents' autistic-like social deficits and school and social adjustment as well as the moderating roles of age and gender in these associations. The sample consisted of 1321 students (48.7% boys) in Grade 1 to Grade 8 from northern Taiwan. Children's and adolescents' autistic-like social deficits were assessed using the Social Responsiveness Scale (SRS), and their school and social adjustment (i.e., academic performance, negative attitudes toward schoolwork/teachers/classmates, behavioral problems at schools, negative peer relationships, and problems with peers) were assessed using the Social Adjustment Inventory for Children and Adolescents (SAICA). Both measures were completed by the mothers of the participants. Results from the linear mixed models demonstrated that autistic-like social deficits were associated with poor academic performance, negative attitudes toward schoolwork, teachers, and classmates, behavioral problems at schools, negative peer relationships, and problematic peer interactions. Moreover, gender and/or age moderated the associations between autistic-like social deficits and school and social adjustment problems. For example, autistic-like social deficits were more strongly related to negative school attitude, school social problems, and negative peer relationships in boys than in girls. Further, autistic-like social deficits were more strongly related to problems with peers in older girls than in older boys or younger children (regardless of gender). In conclusion, the present study suggests that autistic-like social deficits may place children and adolescents at increased risk for social and school maladjustment and that the extent of maladjustment may vary with the child's age and gender and the domains of adjustment under discussion.

    Coronary artery disease (CAD) is the most common cause of death for both men and women. However, over the years, emergency physicians, cardiologists, and other health care practitioners have observed varying outcomes in men and women with symptomatic CAD. Women in general are 10 to 15 years older than men when they develop CAD, but suffer worse postinfarction outcomes compared to age-matched men. This article was developed by the cardiovascular workgroup at the 2014 Academic Emergency Medicine (AEM) consensus conference to identify sex- and gender-specific gaps in the key themes and research questions related to emergency cardiac ischemia care. The workgroup had diverse stakeholder representation from emergency medicine, cardiology, critical care, nursing, emergency medical services, patients, and major policy-makers in government, academia, and patient care. We implemented the nominal group technique to identify and prioritize themes and research questions using electronic mail, monthly conference calls, in-person meetings, and Web-based surveys between June 2013 and May 2014. Through three rounds of nomination and refinement, followed by an in-person meeting on May 13, 2014, we achieved consensus on five priority themes and 30 research questions. The overarching themes were as follows: 1) the full spectrum of sex-specific risk as well as presentation of cardiac ischemia may not be captured by our standard definition of CAD and needs to incorporate other forms of ischemic heart disease (IHD); 2) diagnosis is further challenged by sex/gender differences in presentation and variable sensitivity of cardiac biomarkers, imaging, and risk scores; 3) sex-specific pathophysiology of cardiac ischemia extends beyond conventional obstructive CAD to include other causes such as microvascular dysfunction, takotsubo, and coronary artery dissection, better recognized as IHD; 4) treatment and prognosis are influenced by sex-specific variations in biology, as well as patient

    The purpose of this study was to assess middle-aged Japanese workers for possible gender differences in the risk factors associated with depressive symptoms and suicidal ideation. 5,878 workers (40-60 yr of age) (3,631 males and 2,247 females) were recruited from randomly selected companies in northern Japan. Demographic and lifestyle factors, suicidal ideation rate, and the data for the Brief Job Stress Questionnaire (BJSQ) and the Center for Epidemiologic Studies for Depression scale (CES-D) were obtained from the self-report questionnaires. After adjusting for possible confounding variables, marital status, absent of stress reduction technique and low job compatibility were significant independent risk factors for suicidal ideation among males. In females, marital status, feeling of insufficient sleep and absence of stress reduction techniques were significant independent risk factors after adjusting for all variables. Under the same adjustments, temporary employment also showed a protective effect against female suicidal ideation. In conclusion, our results suggest that factors related to suicidal ideation differed by gender. Different approaches for each gender might be useful in the development of suicide prevention programs. However, interpretation of work-related effects, such as temporary employment, interpersonal conflict and transportation industry, was hampered by lack of data concerning personal income, working hours and organizational commitment. Additional studies are needed to examine the longitudinal relationships between the risk factors associated with suicidal ideation and depressive symptoms. PMID:23268835

    Objectives To determine whether access to rapid access chest pain clinics of people with recent onset symptoms is equitable by age, socioeconomic status, ethnicity and gender, according to need. Design Retrospective cohort study with ecological analysis. Setting Patients referred from primary care to five rapid access chest pain clinics in secondary care, across England. Participants Of 8647 patients aged ≥35 years referred to chest pain clinics with new-onset stable chest pain but no known cardiac history, 7570 with documented census ward codes, age, gender and ethnicity comprised the study group. Patients excluded were those with missing date of birth, gender or ethnicity (n=782) and those with missing census ward codes (n=295). Outcome measures Effects of age, gender, ethnicity and socioeconomic status on clinic attendance were calculated as attendance rate ratios, with number of attendances as the outcome and resident population-years as the exposure in each stratum, using Poisson regression. Attendance rate ratios were then compared with coronary heart disease (CHD) mortality ratios to determine whether attendance was equitable according to need. Results Adjusted attendance rate ratios for patients aged >65 years were similar to younger patients (1.1, 95% CI 1.05 to 1.16), despite population CHD mortality rate ratios nearly 15 times higher in the older age group. Women had lower attendance rate ratios (0.81, 95% CI 0.77 to 0.84) and also lower population CHD mortality rate ratios compared with men. South Asians had higher attendance rates (1.67, 95% CI 1.57 to 1.77) compared with whites and had a higher standardised CHD mortality ratio of 1.46 (95% CI 1.41 to 1.51). Although univariable analysis showed that the most deprived patients (quintile 5) had an attendance rate twice that of less deprived quintiles, the adjusted analysis showed their attendance to be 13% lower (0.87, 95% CI 0.81 to 0.94) despite a higher population CHD mortality rate.

    The exploratory study presented here examines children's ability to recognize another person's need-of-help. This social perception process necessarily precedes the decision to actively help others. Fifty-eight children aged between 5 and 13 completed three experimental paradigms. They were asked to look at black-and-white drawings and to indicate which ones showed somebody in need of help. A control task requiring children to differentiate between pictures of humans and birds measured general categorization abilities. This experimental design enabled us to consider confounding effects of children's developmental status and motivation and to distinguish them from specific need-of-help recognition abilities. As gender and age have been shown to influence social perception as well as helping behavior, we explored whether these factors also have an impact on need-of-help recognition. Children's response accuracies and response times (RTs) were analyzed. We observed clearly higher accuracy rates for younger girls compared to younger boys specifically in the need-of-help recognition tasks. For boys, an age-related performance improvement was found. Younger girls performed at a similarly high level as older girls and boys. No gender differences were observed for children aged over nine. This report provides first evidence that the developmental trajectory of children's ability to recognize another person's need-of-help differs for girls and boys. PMID:24578698

    Objective To investigate correlates of eating disorder psychopathology in adolescent males and females with type 1 diabetes. Method A total of 105 adolescents with type 1 diabetes (42% males), aged 12–20 years, were recruited from the Norwegian Childhood Diabetes Registry in this population-based study. All participants were interviewed with the Child Eating Disorder Examination. Additionally, the Brief Illness Perception Questionnaire, the Adolescent Coping Orientation for Problem Experiences and the Beliefs about Medicines Questionnaire were administered to assess health-related functioning. Clinical data were obtained from the Norwegian Childhood Diabetes Registry. Results Significant gender differences were demonstrated in the pattern of correlates of eating disorder pathology. Among females, eating disorder psychopathology was significantly associated with body mass index adjusted for age and gender, age, insulin restriction, coping, illness perceptions, and perceptions of insulin concern. In a regression model, age, illness perceptions, and insulin restriction remained significantly associated with eating disorder psychopathology, explaining 48% of the variance. None of the variables were associated with eating disorder psychopathology among males. Discussion Greater clinical awareness of illness perceptions, attitudes toward insulin, and insulin restriction may potentially decrease the risk of developing eating disorders among female adolescents with type 1 diabetes, and the subsequent increased morbidity and mortality associated with comorbid type 1 diabetes and eating disorders.

    2011-01-01

    Since the 1990s, several studies involving French centenarians have shown a gender paradox in old age. Even if women are more numerous in old age and live longer than men, men are in better physical and cognitive health, are higher functioning, and have superior vision. If better health should lead to a longer life, why are men not living longer than women? This paper proposes a hypothesis based on the differences in the generational habitus between men and women who were born at the beginning of the 20th century. The concept of generational habitus combines the generation theory of Mannheim with the habitus concept of Bourdieu based on the observation that there exists a way of being, thinking, and doing for each generation. We hypothesized that this habitus still influences many gender-linked behaviours in old age. Men, as “oaks,” seem able to delay the afflictions of old age until a breaking point, while women, as “reeds,” seem able to survive despite an accumulation of health deficits. PMID:22175018

    Background Studies of non-cutaneous and cutaneous malignancies support the hypothesis that poor risk-perception status contributes to health disparity. Objective We evaluated skin cancer risk perceptions across race and other demographic markers using the Health Information National Trends Survey (HINTS) and compared them to discover differences in perception that may contribute to the disparities in skin cancer diagnosis and treatment. Methods Respondents with no prior history of skin cancer were randomly selected to answer questions assessing perceived risk and knowledge of preventive strategies of skin cancer. Logistic regression was performed to identify associations between perceptions of skin cancer and demographic variables including self-described race, age, sex, education, income, and health insurance status. Results Blacks, the elderly, and people with less education perceived themselves as at lower risk of developing skin cancer. They, along with Hispanics, were also more likely to believe that one cannot lower their skin cancer risk and that there are so many different recommendations on how to prevent skin cancer that it makes it difficult to know which ones to follow. Lower education also correlated with greater reluctance to have a skin exam. Limitations HINTS is a cross-sectional instrument, thus it only provides a snapshot of skin cancer perceptions. Conclusion Uncertainty and altered perceptions are more common in the skin cancer risk perceptions of ethnic minorities, the elderly, and those with less education. These are the same groups that are subject to disparities in skin cancer outcomes. Educational programs directed at these demographic groups may help to reduce the skin cancer-related health disparities. PMID:21875760

    2014-01-01

    Bronchiolitis is the most common reason for admission to hospital in the first year of life. There is tremendous variation in the clinical management of this condition across Canada and around the world, including significant use of unnecessary tests and ineffective therapies. This statement pertains to generally healthy children ≤2 years of age with bronchiolitis. The diagnosis of bronchiolitis is based primarily on the history of illness and physical examination findings. Laboratory investigations are generally unhelpful. Bronchiolitis is a self-limiting disease, usually managed with supportive care at home. Groups at high risk for severe disease are described and guidelines for admission to hospital are presented. Evidence for the efficacy of various therapies is discussed and recommendations are made for management. Monitoring requirements and discharge readiness from hospital are also discussed.

A validated 12-item Bem Sex Role Inventory (BSRI) was used to classify participants in gender roles (Masculine, Feminine, Androgynous, and Undifferentiated) using research site medians of femininity and masculinity as cut-off points. Poisson regressions were fitted to estimate the prevalence ratios (PR) of depression for each gender role compared to the masculine role, adjusting for sex, sufficiency of income, education, marital status, self-rated health, and chronic conditions. Results Among men, 31.2% were androgynous, 26% were masculine, 14.4% were feminine, and 28.4% were undifferentiated; among women, the corresponding percentages were 32.7%, 14.9%, 27%, and 25.4%. Both in men and in women, depressive symptoms (CES-D≥16) were more prevalent in those endorsing the undifferentiated type, compared to masculine, feminine or androgynous groups. However, after adjusting for potential confounders, compared to the masculine group only those endorsing the androgynous role were 28% less likely to suffer from depression: PR of 0.72 (95% CI: 0.55–0.93). In fully adjusted models, prevalence rates of depression were not different from masculine participants in the two other gender groups of feminine and undifferentiated. Conclusions Androgynous roles were associated with lower rates of depression in older adults, independently of being a man or a woman. PMID:26771828

    The adult human brain shrinks slowly with age, but the regional specificity and tissue class specificity of this loss is unclear. Subjects (n=122) were healthy aged participants in a longitudinal cohort who undergo periodic standardized cognitive and clinical examination. Multi-spectral segmentation of magnetic resonance images into grey matter (GM), white matter (WM) and CSF was performed on cross-sectional image data using a custom template and calculated prior probability maps. Global differences were evaluated by fitting a regression model for absolute and normalized subject GM, WM, and CSF values. Global and regional patterns of GM, WM and CSF differences were assessed using optimized voxel-based morphometry (VBM). GM volume decreased with age at a rate of 2.4 cm(3)/year (-0.18%/year); CSF increased by 2.5 cm(3)/year (0.20%/year). Regression analyses showed no significant decrease in WM volume, but a focal WM decrease with age was detected in the anterior corpus callosum using VBM. Diffuse reductions of GM volume were seen with age in the frontal, parietal, and temporal cortex, cerebellum and basal ganglia. Relative regional differences in cortical GM volume with age occurred in the frontal, parietal and temporal lobes, but not in medial temporal lobe or in posterior cingulate. We did not observe significant gender effects. These findings establish a baseline for comparison with pathologic changes in human brain volume between ages 58 and 95 years. PMID:16774798

    Objective: Multiple studies worldwide have supported the predictive validity of self-rated health (SRH) with regard to disability and mortality among elderly people. Although SRH is an important study topic providing clues to enhance a person’s quality of life, there is currently insufficient data on age- and gender-specific differences among factors associated with SRH in Japan, particularly in rural areas. The present study examined the factors associated with SRH of a segment of Japan’s rural population by age- and gender-specific analysis. Methods: We used data from a cohort study of all users who underwent an annual health checkup at a public clinic in a rural area. The study subjects were 155 male and 169 female users from June 2009 to August 2010 who agreed to participate in this study. We divided the study subjects into 4 categories as follows: men aged less than 65, women aged less than 65, men aged 65 and over, and women aged 65 and over. The subjects who responded positively to the SRH-related questions were defined as the high SRH group, and those who responded negatively were defined as the low SRH group. We then compared the data between the high and the low groups in each category. Results: In all four categories, there were statistically significant differences in regular hospital or clinic attendance between the high and low SRH groups. In all four categories, there were no significant differences in eating or exercise habits between the two SRH groups. Conclusion: Because regular hospital or clinic attendance by a subject is indicative of the presence of chronic health problems, it is natural for the subject’s perception of their own health to be negative. However, rural physicians should provide patients with emotional and psychological support to deal with any health-related concerns positively. PMID:25648990

    Age-related Macular Degeneration (AMD) is one of the major causes of vision loss and blindness in ageing population. Currently, there is no cure for AMD, however early detection and subsequent treatment may prevent the severe vision loss or slow the progression of the disease. AMD can be classified into two types: dry and wet AMDs. The people with macular degeneration are mostly affected by dry AMD. Early symptoms of AMD are formation of drusen and yellow pigmentation. These lesions are identified by manual inspection of fundus images by the ophthalmologists. It is a time consuming, tiresome process, and hence an automated diagnosis of AMD screening tool can aid clinicians in their diagnosis significantly. This study proposes an automated dry AMD detection system using various entropies (Shannon, Kapur, Renyi and Yager), Higher Order Spectra (HOS) bispectra features, Fractional Dimension (FD), and Gabor wavelet features extracted from greyscale fundus images. The features are ranked using t-test, Kullback-Lieber Divergence (KLD), Chernoff Bound and Bhattacharyya Distance (CBBD), Receiver Operating Characteristics (ROC) curve-based and Wilcoxon ranking methods in order to select optimum features and classified into normal and AMD classes using Naive Bayes (NB), k-Nearest Neighbour (k-NN), Probabilistic Neural Network (PNN), Decision Tree (DT) and Support Vector Machine (SVM) classifiers. The performance of the proposed system is evaluated using private (Kasturba Medical Hospital, Manipal, India), Automated Retinal Image Analysis (ARIA) and STructured Analysis of the Retina (STARE) datasets. The proposed system yielded the highest average classification accuracies of 90.19%, 95.07% and 95% with 42, 54 and 38 optimal ranked features using SVM classifier for private, ARIA and STARE datasets respectively. This automated AMD detection system can be used for mass fundus image screening and aid clinicians by making better use of their expertise on selected images that

    Complete blood counts and blood biochemical analyses are laboratory tests that allow the monitoring of physiological condition, nutrition, and health in free-living or captive wild animals. When interpreting these tests, it is essential to compare the results with reference ranges that are suitable for the species. Few studies have been conducted on the hematological and biochemical characteristics of Tayassu tajacu, particularly for animals raised in the Amazon biome. The objectives of this study were to evaluate the influence of age and gender on the hematological and biochemical profiles of captive T. tajacu, and to establish reference intervals for these parameters. Complete blood counts and biochemical analyses were performed using manual methods and semi-automatic equipment, respectively. There were significant differences in relation to age in hematocrit and hemoglobin levels, and mean cell volumes, in captive T. tajacu. No basophils were observed, and the neutrophil:lymphocyte ratio was less than 1. Levels of total protein, urea, phosphorus, and alkaline phosphatase were significantly affected by age (P < 0.05). Gender did not affect any of the results. The hematological and biochemical parameters for this species were determined, and may be used as reference ranges for captive T. tajacu. PMID:26634461

    Carnosine is found in high concentrations in skeletal muscles, where it is involved in several physiological functions. The muscle carnosine content measured within a population can vary by a factor 4. The aim of this study was to further characterize suggested determinants of the muscle carnosine content (diet, gender and age) and to identify new determinants (plasma carnosinase activity and testosterone). We investigated a group of 149 healthy subjects, which consisted of 94 men (12 vegetarians) and 55 women. Muscle carnosine was quantified in M. soleus, gastrocnemius and tibialis anterior using magnetic resonance proton spectroscopy and blood samples were collected to determine CNDP1 genotype, plasma carnosinase activity and testosterone concentrations. Compared to women, men have 36, 28 and 82% higher carnosine concentrations in M. soleus, gastrocnemius and tibialis anterior muscle, respectively, whereas circulating testosterone concentrations were unrelated to muscle carnosine levels in healthy men. The carnosine content of the M. soleus is negatively related to the subjects' age. Vegetarians have a lower carnosine content of 26% in gastrocnemius compared to omnivores. In contrast, there is no difference in muscle carnosine content between omnivores with a high or low ingestion of β-alanine. Muscle carnosine levels are not related to the polymorphism of the CNDP1 gene or to the enzymatic activity of the plasma carnosinase. In conclusion, neither CNDP1 genotype nor the normal variation in circulating testosterone levels affects the muscular carnosine content, whereas vegetarianism, female gender and increasing age are the factors associated with reduced muscle carnosine stores.

    Purpose: Comparing radiation therapy utilization rates (RTUR) to those predicted by best evidence is a useful measure of the equity and accessibility of service delivery. In this study the RTUR for melanoma was established for British Columbia, Canada, and compared with the rate suggested by the evidence. Demographic variables, specifically age, gender, and geography that influenced the RTUR were examined with a view to identifying methods of improving underutilization. Methods and Materials: The RTUR in the management of malignant melanoma was taken from British Columbia Cancer registry data for 1986 to 1998. Variations in utilization based on age, gender, health authority, stage of disease, and referral patterns were analyzed. Results: An RTUR of 11% was identified. This was consistent over time. Referral rates decreased between 1986 and 1998. RT is used mostly for later stage disease. Males were more likely to receive RT than females, related to later stage of disease in men. Referral rates decreased, but RTUR for referred cases increased, in health authorities that did not have a cancer center. Conclusions: Use of RT is influenced by age and by stage of disease. Overall RTUR in British Columbia is lower than suggested by best evidence. Referral patterns are influenced by geography. RTUR was higher in males, consistent with a different pattern of disease in males compared with females.

    Attention deficit/hyperactivity disorder (ADHD) is one of the most common psychiatric disorders in childhood and adolescence. Rating the severity of psychopathology and symptom load is essential in daily clinical practice and in research. The parent and teacher ADHD-Rating Scale (ADHD-RS) includes inattention and hyperactivity/impulsivity subscales and is one of the most frequently used scales in treatment evaluation of children with ADHD. An extended version, mADHD-RS, also includes an oppositional defiant disorder subscale. The partial credit Rasch model, which is based on item response theory, was used to test the psychometric properties of this scale in a sample of 566 Danish school children between 6 and 16 years of age. The results indicated that parents and teachers had different frames of reference when rating symptoms in the mADHD-RS. There was support for the unidimensionality of the three subscales when parent and teacher ratings were analyzed independently. Nonetheless, evidence for differential item functioning was found across gender and age for specific items within each of the subscales. The findings expand existing psychometric information about the mADHD-RS and support its use as a valid and reliable measure of symptom severity when used in age- and gender-stratified materials.

    A single early prostate-specific antigen (PSA) level has been correlated with a higher likelihood of prostate cancer diagnosis and death in younger men. PSA testing in older men has been considered of limited utility. We evaluated prostate cancer death in relation to age and PSA level immediately prior to prostate cancer diagnosis. Using the Veterans Affairs database, we identified 230,081 men aged 50–89 years diagnosed with prostate cancer and at least one prior PSA test between 1999 and 2009. Prostate cancer-specific death over time was calculated for patients stratified by age group (e.g., 50–59 years, through 80–89 years) and PSA range at diagnosis (10 ranges) using Kaplan–Meier methods. Risk of 10-year prostate cancer mortality across age and PSA was compared using log-rank tests with a Bonferroni adjustment for multiple testing. 10.5% of men diagnosed with prostate cancer died of cancer during the 10-year study period (mean follow-up = 3.7 years). Higher PSA values prior to diagnosis predict a higher risk of death in all age groups (p < 0.0001). Within the same PSA range, older age groups are at increased risk for death from prostate cancer (p < 0.0001). For PSA of 7–10 ng/mL, cancer-specific death, 10 years after diagnosis, increased from 7% for age 50–59 years to 51% for age 80–89 years. Men older than 70 years are more likely to die of prostate cancer at any PSA level than younger men, suggesting prostate cancer remains a significant problem among older men (even those aged 80+) and deserves additional study.

    In magnetic resonance imaging based brain morphometry, Gaussian smoothing is often applied to increase the signal-to-noise ratio and to increase the detection power of statistical parametric maps. However, most existing studies used a single smoothing filter without adequately justifying their choices. In this article, we want to determine the extent for which performing a morphometry analysis using multiple smoothing filters, namely conducting a scale space search, improves or decreases the detection power. We first compared scale space search with single-filter analysis through a simulated population study. The multiple comparisons in our four-dimensional scale space searches were corrected for using a unified P-value approach. Our results illustrate that, compared with a single-filter analysis, a scale space search analysis can properly capture the variations in analysis results caused by variations in smoothing, and more importantly, it can obviously increase the sensitivity for detecting brain morphometric changes. We also show that the cost of an increased critical threshold for conducting a scale space search is very small. In the second experiment, we investigated age and gender effects on cortical volume, thickness, and surface area in 104 normal subjects using scale space search. The obtained results provide a perspective of scale space theory on the morphological changes with age and gender. These results suggest that, in exploratory studies of aging, gender, and disease, conducting a scale space search is essential, if we are to produce a complete description of the structural changes or abnormalities associated with these dimensions.

    Incremental exercise testing is frequently used as a tool for evaluating determinants of endurance performance. The available reference values for the peak oxygen uptake (VO2peak), % of VO2peak, running speed at the lactate threshold (vLT), running economy (RE), and maximal running speed (vpeak) for different age, gender, and disciplines are not sufficient for the elite athletic population. The key variables of 491 young athletes (age range 12-21 years; 250 males, 241 females) assessed during a running step test protocol (2.4 m s(-1); increase 0.4 m s(-1) 5 min(-1)) were analysed in five subgroups, which were related to combat-, team-, endurance-, sprint- and power-, and racquet-related disciplines. Compared with female athletes, male athletes achieved a higher vpeak (P = 0.004). The body mass, lean body mass, height, abs. VO2peak (ml min(-1)), rel. VO2peak (ml kg(-1) min(-1)), rel. VO2peak (ml min(-1) kg(-0.75)), and RE were higher in the male participants compared with the females (P < 0.01). The % of VO2 at vLT was lower in the males compared with the females (P < 0.01). No differences between gender were detected for the vLT (P = 0.17) and % of VO2 at vLT (P = 0.42). This study is one of the first to provide a broad spectrum of data to classify nearly 500 elite athletes aged 12-21 years of both gender and different disciplines. PMID:26413450

    Broilers that are susceptible to pulmonary hypertension syndrome (PHS, ascites) have an elevated pulmonary arterial pressure (PAP) when compared with PHS-resistant broilers. Two distinctly different syndromes, pulmonary arterial hypertension (PAH) and pulmonary venous hypertension (PVH), both are associated with increases in PAP. Pulmonary arterial hypertension occurs when the right ventricle must elevate the PAP to overcome increased resistance to flow through restrictive pulmonary arterioles upstream from the pulmonary capillaries. In contrast, PVH is commonly caused by increased downstream (post-capillary) resistance. The sites of resistance to pulmonary blood flow are deduced by making contemporaneous measurements of the PAP and the wedge pressure (WP), and calculating the trans-pulmonary pressure gradient (TPG = PAP-WP). We obtained PAP and WP values from 8, 12, 16, 20 and 24 wk old anesthetized male and female broilers from a PHS-susceptible line. Pressures were recorded as a catheter was advanced through a wing vein to the pulmonary artery and onward until the WP was obtained. In addition to gender and age comparisons of vascular pressure gradients, the data also were pooled to obtain three cohorts for broilers having the lowest PAP values (n = 52; range: 12 to 22.9 mmHg), intermediate PAP values (n = 63; range: 23 to 32.9 mmHg), and highest PAP values (n = 62; range: 33 to 62 mmHg) independent of age or gender. Within each of the age, gender and PAP cohort comparisons, broilers with elevated PAP consistently exhibited the hemodynamic characteristics of PAH (elevated PAP and TPG combined with a normal WP) and not PVH (elevated PAP and WP combined with a normal or reduced TPG). Susceptibility to PHS can be attributed primarily to pulmonary arterial hypertension associated with increased pre-capillary (arteriole) resistance. PMID:20709965

    Background Elderly patients are at particular risk for bacteremia and sepsis. Atypical presentation may complicate the diagnosis. We studied patients with bacteremia, in order to assess possible age-related effects on the clinical presentation and course of severe infections. Methods We reviewed the records of 680 patients hospitalized between 1994 and 2004. All patients were diagnosed with bacteremia, 450 caused by Escherichia coli and 230 by Streptococcus pneumoniae. Descriptive analyses were performed for three age groups (< 65 years, 65–84 years, ≥ 85 years). In multivariate analyses age was dichotomized (< 65, ≥ 65 years). Symptoms were categorized into atypical or typical. Prognostic sensitivity of CRP and SIRS in identifying early organ failure was studied at different cut-off values. Outcome variables were organ failure within one day after admission and in-hospital mortality. Results The higher age-groups more often presented atypical symptoms (p <0.001), decline in general health (p=0.029), and higher in-hospital mortality (p<0.001). The prognostic sensitivity of CRP did not differ between age groups, but in those ≥ 85 years the prognostic sensitivity of two SIRS criteria was lower than that of three criteria. Classical symptoms were protective for early organ failure (OR 0.67, 95% CI 0.45-0.99), and risk factors included; age ≥ 65 years (OR 1.65, 95% CI 1.09-2.49), comorbid illnesses (OR 1.19, 95% CI 1.02-1.40 per diagnosis), decline in general health (OR 2.28, 95% CI 1.58-3.27), tachycardia (OR 1.50, 95% CI 1.02-2.20), tachypnea (OR 3.86, 95% CI 2.64-5.66), and leukopenia (OR 4.16, 95% CI 1.59-10.91). Fever was protective for in-hospital mortality (OR 0.46, 95% CI 0.24-0.89), and risk factors included; age ≥ 65 years (OR 15.02, 95% CI 3.68-61.29), ≥ 1 comorbid illness (OR 2.61, 95% CI 1.11-6.14), bacteremia caused by S. pneumoniae (OR 2.79, 95% CI 1.43-5.46), leukopenia (OR 4.62, 95% CI 1.88-11.37), and number of early

    The objectives of this study were to examine (1) whether the onset of sexually transmitted infections (STI) through age 30 differed for youths who received a social developmental intervention during elementary grades compared to those in the control condition; (2) potential social-developmental mediators of this intervention; and (3) the extent to which these results differed by ethnicity. A nonrandomized controlled trial followed participants to age 30, 18 years after the intervention ended. Three intervention conditions were compared: a full-intervention group, assigned to intervention in grades 1 through 6; a late intervention group, assigned to intervention in grades 5 and 6 only; and a no-treatment control group. Eighteen public elementary schools serving diverse neighborhoods including high-crime neighborhoods of Seattle are the setting of the study. Six hundred eight participants in three intervention conditions were interviewed from age 10 through 30. Interventions include teacher training in classroom instruction and management, child social and emotional skill development, and parent workshops. Outcome is the cumulative onset of participant report of STI diagnosis. Adolescent family environment, bonding to school, antisocial peer affiliation, early sex initiation, alcohol use, cigarette use, and marijuana use were tested as potential intervention mechanisms. Complementary log-log survival analysis found significantly lower odds of STI onset for the full-intervention compared to the control condition. The lowering of STI onset risk was significantly greater for African Americans and Asian Americans compared to European Americans. Family environment, school bonding, and delayed initiation of sexual behavior mediated the relationship between treatment and STI hazard. A universal intervention for urban elementary school children, focused on classroom management and instruction, children's social competence, and parenting practices may reduce the onset of STI

    Objectives To examine the relationships between physical function and gender-stereotyped traits and whether these relationships are modified by sex or social context. Methods A total of 1995 community-dwelling older adults from the International Mobility in Aging Study (IMIAS) aged 65 to 74 years were recruited in Natal (Brazil), Manizales (Colombia), Tirana (Albania), Kingston (Ontario, Canada), and Saint-Hyacinthe (Quebec, Canada). We performed a cross-sectional analysis. Study outcomes were mobility disability, defined as having difficulty in walking 400 meters without assistance or climbing a flight of stairs without resting, and low physical performance, defined as a score < 8 on the Short Physical Performance Battery. The 12-item Bem Sex Role Inventory (BSRI) was used to classify participants into four gender roles (Masculine, Feminine, Androgynous, and Undifferentiated) using site-specific medians of femininity and masculinity as cut-off points. Poisson regression models were used to estimate prevalence rate ratios (PRR) of mobility disability and poor physical performance according to gender roles. Results In models adjusted for sex, marital status, education, income, and research site, when comparing to the androgynous role, we found higher prevalence of mobility disability and poor physical performance among participants endorsing the feminine role (PRR = 1.20, 95% confidence interval (CI) 1.03–1.39 and PRR = 1.37, CI 1.01–1.88, respectively) or the undifferentiated role (PRR = 1.23, 95% CI 1.07–1.42 and PRR = 1.58, CI 1.18–2.12, respectively). Participants classified as masculine did not differ from androgynous participants in prevalence rates of mobility disability or low physical performance. None of the multiplicative interactions by sex and research site were significant. Conclusion Feminine and undifferentiated gender roles are independent risk factors for mobility disability and low physical performance in older adults. Longitudinal

    2015-01-01

    The aim of this study was to analyse the effects of age and gender (and their interaction) on a stretch shortening cycle solicited during a hopping task. For this aim, 147 girls and 148 boys aged 11 to 20 years, who were enrolled in middle school or secondary school with no experience in sport activity, or training less than three times per week, performed 3×5 hops in place. Leg-stiffness, jump-height and reactive-strength indices were assessed using an accelerometer (Myotest). The participants were selected in order to form five age groups: 11 12, 13-14, 15-16, 17-18 and 19-20 years. Regression analysis between force and centre of mass displacement revealed spring-mass behaviour for all groups (r2=.73-.89), meaning that beginning at the age of 11 years, children are able to perform complex inter-muscular coordination of the lower limbs, revealing efficient neural control early in childhood. Leg stiffness increased from 24.7 ± 10.6 kN · m−1 at 11-12 years to 44.1 ± 14 kN · m−1 in boys, with a small increase until 16 years (+17%) and a large increase between 17 and 20 years (+32.7%). In girls, leg stiffness increased from 26.6 ± 9 kN · m−1 at 11-12 years to 39.4 ± 10.9 kN · m−1 at 19-20 years, with a curious decrease in leg stiffness at 17-18 years, probably due to an increase in the percentage of fat at this age (25%). While no gender effect was found, the reactive-strength index revealed that, from 15-16 years onward, boys were better able to produce high levels of force in a shorter time than girls. The age of 15-16 years is a threshold of maturity and gender differentiation, where the boys investigated are more efficient in the stretch shortening cycle. PMID:26985131

    Objective To elucidate the associations between polypharmacy and age- and gender-specific risks of admission for fall-related fractures. Design Nested case–control study. Setting This analysis was randomly selected from all elderly beneficiaries in 2007–2008, and represents some 30% of the whole older insurers using Taiwan's National Health Insurance Research Database. Participants We identified 5933 cases newly admitted for fall-related fractures during 2007–2008, and 29 665 random controls free from fracture. Primary and secondary outcome measures Polypharmacy was defined as the use of fall-related drugs of four or more categories of medications and prescribed related to fall within a 1-year period. Logistic regression models were employed to estimate the ORs and related 95% CIs. The interaction of polypharmacy with age and sex was assessed separately. Results Compared with those who consumed no category of medication, older people who consumed 1, 2, 3 and ≥4 categories of medications were all at significantly increased odds of developing fall-related fractures, with a significant dose–gradient pattern (β=0.7953; p for trend <0.0001). There were significant interactions between polypharmacy and age, but no significant interactions between polypharmacy and gender. The dose–gradient relationship between number of medications category and risk of fall-related fractures was more obvious in women than in men (β=0.1962 vs β=0.1873). Additionally, it was most evident in older people aged 75–84 years (β=0.2338). Conclusions This population-based study in Taiwan confirms the link between polypharmacy and increased risk of fall-related fractures in older people; and highlights that elderly women and older people aged 75–84 years will be the targeted participants for further prevention from fall-related fractures caused by polypharmacy.

    This paper uses recent data from the Wisconsin Longitudinal Study (N = 5,220) to explore gender differences in the extent to which adults in their 50s and 60s provide informal help to their adult children, elderly parents and friends We find that both men and women report very high levels of helping kin and nonkin alike, though women do more to assist elderly parents and women provide much more emotional support to others than do men. Men provide more assistance than do women with "housework, yard work and repairs." As they retire from the workforce, married men become significantly more involved in the care of their grandchildren, virtually eliminating any gender difference by the time they are in their 60s.

    Background. Recent clinical studies have shown that, in some degenerative retinal diseases, like age-related macular degeneration (AMD), the sensitivity of the rods decreases more rapidly than the sensitivity of the cones. The aim of this study was to evaluate if there is a correlation between the presence of hard drusen at the macular level and the rod damage responsible for the reduction in scotopic retinal sensitivity in subjects at risk for AMD. Methods. The authors selected 24 subjects (14 men and 10 women) with an average age of 67.25 ± 5.7 years. Macular hard drusen were present in 50% of the subjects at the fundus oculi exam. The researchers evaluated the retinal sensitivity to light in mesopic and scotopic conditions of each subject with an MP-1 scotopic microperimeter (MP-1S). Results. In subjects with hard drusen in the fundus oculi examination, there was a statistically significant reduction in scotopic retinal sensitivity, while the mesopic retinal sensitivity was not compromised. Conclusion. This study revealed how the presence of hard drusen at the macular level is associated with a reduction in scotopic retinal sensitivity compared to a control group of healthy subjects. Retinal functionality in a scotopic setting examined with MP-1S could be useful in early diagnosis of AMD. PMID:25548774

    Many older adults face challenges that prevent them from accomplishing common daily activities such as moving around, home maintenance, and leisure activities. There is still a need to examine and understand how environmental factors impact daily participation across gender. This study sought to make a qualitative comparison of gender differences regarding environmental barriers to participation in daily occupations from the perspectives of older adults who live alone in Puerto Rico. Twenty-six Hispanic older adults, 70 years or older participated in this study. We used a descriptive qualitative research design in which researchers administered an in-depth interview to each participant. The results elucidated that women were more likely than men to experience restricted participation due to lack of accessibility of the built environment and transportation systems. The findings could help with the development of tailored, occupation-based, preventive interventions that address gender specific environmental barriers and promote greater participation among both women and men. Further research is required to explore whether these environmental barriers to occupational participation remain consistent across living situations, socioeconomic status and ethnicity.

    It is well established that older drivers' fragility is an important factor associated with higher levels of fatal crash involvement for older drivers. There has been less research on age-related fragility with respect to the sort of minor injuries that are more common in injury crashes. This study estimates a quantity that is related to injury fragility: the probability that a driver or a passenger of that driver will be injured in crashes involving two cars. The effects of other factors apart from drivers' fragility are included in this measure, including the fragility of the passengers, the crashworthiness of cars driven, seatbelt use by the occupants, and characteristics of crashes (including configuration and impact speed). The car occupant injury liability estimates appropriately includes these factors to adjust risk curves by age, gender, and speed limit accounting for overrepresentation in crashes associated with fragility and these other factors.

    This study investigated how target sex, target age, and expressive ambiguity influence emotion perception. Undergraduate participants (N = 192) watched morphed video clips of eight child and eight adult facial expressions shifting from neutral to either sadness or anger. Participants were asked to stop the video clip when they first saw an emotion appear (perceptual sensitivity) and were asked to identify the emotion that they saw (accuracy). Results indicate that female participants identified sad expressions sooner in female targets than in male targets. Participants were also more accurate identifying angry facial expressions by male children than by female children. Findings are discussed in terms of the effects of ambiguity, gender, and age on the perception of emotional expressions. PMID:25154116

    Using the frameworks of the life course perspective and continuity theory, this study focuses on the association among working people between gender and specific leisure activities, social interests and individuals' preferred retirement age. The study is based on the first wave of the Norwegian Life Course, Aging and Generation (NorLAG) study, concentrating on workers 40-61 years old, thinking about retirement (n=2339). Results indicate that some leisure activities and interests are associated with preferences for early retirement, while other activities and interests are associated with preferences for later retirement. Different leisure activities and interests are related to men's and women's retirement preferences. Single women prefer to retire later than married women. Findings suggest that leisure activities and social interests have different relevance for men's and women's preferences for leaving the labor force. Women active in voluntary work prefer later retirement, while men engaged in fishing and hunting prefer early retirement. PMID:23350345

    Cav2.1 Ca2+ channels (P/Q-type), which participate in various key roles in the central nervous systems by mediating calcium influx, are extensively spliced. One of its alternatively-spliced exon is 37, which forms part of the EF hand. The expression of exon 37a (EFa form), but not exon 37b (EFb form), confers the channel an activity-dependent enhancement of channel opening known as Ca2+-dependent facilitation (CDF). In this study, we analyzed the trend of EF hand splice variant distributions in mouse, rat and human brain tissues. We observed a developmental switch in rodents, as well as an age and gender bias in human brain tissues, suggestive of a possible role of these EF hand splice variants in neurophysiological specialization. A parallel study performed on rodent brains showed that the data drawn from human and rodent tissues may not necessarily correlate in the process of aging. PMID:17291689

    This cross-sectional study investigated self-esteem in relation to age, gender, ethnicity, and risk behaviors among a sample of nonmainstream students. Participants were 149 students in the 6th to 12th grades from two nonmainstream schools (one charter and one alternative school). Self-esteem and youth risk behaviors were determined by using a modified version of the Rosenberg Self-Esteem Scale (Rosenberg, 1965) and the National Alternative High School Youth Risk Behavior Survey (Grunbaum et al., 1999), respectively. Results indicated that nonmainstream students with high self-esteem were more likely to engage in their first sexual experience and to begin marijuana use later in life. African American students reported having their first sexual experience at an older age, but having more sexual partners than did Latino students. The implications of these findings are discussed.

    This study was conducted to investigate the clinical data of two cases of canine sialolithiasis and to analyze 29 cases identified in the Veterinary Medical Database by year of admission, breed, gender, and age. Medical records from the University of Missouri Veterinary Medical Teaching Hospital were reviewed and two dogs diagnosed with sialolithiasis (calcium oxalate) were identified between 1990 and 2010. The two dogs had cervical or pharyngeal sialocele and were successfully treated by sialolith removal and concurrent sialoadenectomy. Signalments of dogs with sialolithiasis between 1964 and 2010 were collected from the Veterinary Medical Database and evaluated. Several breeds of dogs were represented and the 10 to <15 yr old age group was shown to have significant association with sialolithiasis. Sialolithiasis is a rare veterinary condition. In this study, older dogs were at higher risk. In dogs, concurrent sialocele was common and good outcome could be expected after surgical removal of sialoliths with concurrent sialoadenectomy.

    Controversies concerning the association between obesity and acute myocardial infarction (AMI) are still ongoing in Japan. We investigated the association between obesity defined by body mass index of 25 kg/m(2) or higher and AMI by a case-control study using data from 1199 AMI cases and 4056 apparently healthy controls. The analysis was performed in age- and sex-matched samples of 621 case-control pairs younger than 80 years and in crude samples aged 40-79 years divided into 10-year age groups. Prevalence of obesity, diabetes, current smoking, hypertension, and hypercholesterolemia were compared between cases and controls, and a multivariable odds ratio (OR) of AMI was calculated for each risk factor in various age groups. The OR (95 % confidence interval (CI)) of AMI for obesity was 1.63 (1.23-2.17), P = 0.0008 in men younger than 80 years; 2.65 (1.41-5.00), P = 0.0025 in women younger than 80 years; 2.23 (1.46-3.41), P = 0.0002 in men aged 59 years or younger; 1.34 (0.90-2.01), P = 0.1510 in men aged 60-79 years; and 2.98 (1.56-5.71), P = 0.0010 in women aged 60-79 years using paired samples. The OR (95 % CI) of AMI for obesity was 4.92 (2.53-9.58), P < 0.0001 in men aged 40-49 years; 1.54 (1.07-2.21), P = 0.0197 in men aged 50-59 years; 1.07 (0.69-1.66), P = 0.7717 in men aged 60-69 years; 2.24 (1.20-4.20), P = 0.0118 in men aged 70-79 years; 2.48 (1.12-5.48), P = 0.0245 in women aged 60-69 years; and 3.05 (1.46-6.37), P = 0.0029 in women aged 70-79 years using crude samples. The association between obesity and AMI was age- and gender-dependent in a Japanese population. PMID:22975714

    This study focused on the influence of gender, age and emotion regulation on coping strategies among university students in Botswana. Sixty-four males and 64 females, ranging in age from 18 to 29 years completed the Difficulty in Emotion Regulation Scale and the Coping Strategy Inventory. Female students used wishful thinking and problem-focused disengagement more than male students; however, there were no other significant gender differences in coping strategies. Older students were more likely to use problem-solving, cognitive restructuring and express emotion coping strategies. In addition, problems in emotion regulation significantly predicted problem-and emotion-focused engagement, problem- and emotion-focused disengagement and coping strategies. There was a unique finding that non-acceptance of emotional responses, a type of emotion suppression, was positively correlated with problem solving, cognitive restructuring, expressing emotion, social support, problem avoidance and wishful thinking coping strategies. Cultural context and implications for student well-being and university support are discussed. PMID:24910491

    The human hyoid bone supports the base of the tongue and is involved in breathing, chewing, and swallowing as well as in the muscle movements associated with articulation. Accordingly it plays an important bone for a human to live. It is a very interesting organ also in multiple special area, including anatomy, mastication, swallowing, articulation, and also forensic medicine. In the morphological study of the human hyoid bone, there is a comparative anthropological research early in 1900, whereas the metrological research has been little reported later. We first used MDCT, and recorded each organic hyoid locus with a three-dimensional image for three-dimensional morphometry of gender differences, age-related changes, and the morphologic characters of the hyoid bone, and compared them with the results of our predecessors. By measuring the volume of the human hyoid bone, we identified gender difference at high rates, and estimated a certain level of ages based on the ossification at the junction area of the hyoid body and greater horns observed. Our results can be applied in the forensic medicine. By examining 600 cases, atypical horseshoes-shapes were found and the existence of the hyoid bone protrusion was demonstrated at high rates.

    We tested the null hypotheses that neither age, gender nor muscle pre-cocontraction state affect the latencies of changes in upper extremity kinematics or elbow muscle activity following an impulsive force to the hand. Thirty eight healthy young and older adult volunteers lay prone on an apparatus with shoulders flexed 75 degrees and arms slightly flexed. The non-dominant hand was subjected to three trials of impulsive loading with arm muscles precontracted to 25, 50 or 75% of maximum pre-cocontraction levels. Limb kinematic data and upper extremity electromyographic (EMG) activity were acquired. The results showed that pre-cocontraction muscle level (p < 0.001) and gender (p < 0.05 for wrist and shoulder) affected joint displacement onset times and age affected EMG onset times (p < 0.05). The peak applied force (F1) occurred a mean (± SD) 27 (± 2) msec after impact. The latencies for the wrist, elbow and shoulder displacements were 21 ± 3 msec, 29 ± 5 msec and 34 ± 7 msec, respectively. Because the latencies for elbow flexion and lateral triceps EMG were 23 ± 5 msec and 84 ± 8 msec, respectively, muscle pre-activation rather than stretch reflexes prevent arm buckling under impulsive end loads.

    This study compared flow-mediated dilatation (FMD), peripheral artery tonometry (PAT), and serum nitric oxide (NO) measures of endothelial function in patients with peripheral artery disease (PAD) against age/gender matched controls. 25 patients (mean age: 72.4 years, M : F 18 : 7) with established PAD and an age/gender matched group of 25 healthy controls (mean age: 72.4 years, M : F 18 : 7) were studied. Endothelial function was measured using the % FMD, reactive hyperemia index (RHI) using PAT and serum NO (μmol). Difference for each method between PAD and control patients and correlation between the methods were investigated. FMD and RHI were lower in patients with PAD (median FMD for PAD = 2.16% versus control = 3.77%, p = 0.034 and median RHI in PAD = 1.64 versus control = 1.92, p = 0.005). NO levels were not significantly different between the groups (PAD median = 7.70 μmol, control median = 13.05 μmol, p = 0.662). These results were obtained in elderly patients and cannot be extrapolated to younger individuals. FMD and PAT both demonstrated a lower hyperaemic response in patients with PAD; however, FMD results in PAD patients were unequivocally reduced whereas half the PAD patients had RHI values above the established threshold for endothelial dysfunction. This suggests that FMD is a more appropriate method for the measurement of NO-mediated endothelial function. PMID:26942010

    Objective The purpose of this study was to (1) describe the distribution of Chlamydia trachomatis (CT) and Human Immunodeficiency Virus (HIV) cases across gender and age groups in Libreville (Gabon); (2) examine Gabonese Sexually Transmitted Infections (STIs)-related risk behaviour. Methods The sampled population was people attending the “Laboratoire National de Santé Plublique”. Between 2007 and 2011, 14 667 and 9 542 people respectively, were tested for CT and HIV infections. 1 854 of them were tested for both infections. We calculated CT and HIV rates across gender and age groups. Also analysed was the groups' contribution to the general CT and HIV epidemiology. STIs-related risk behaviours were assessed in 224 men and 795 women (between July 2011 and March 2013) who agreed and answered a questionnaire including questions on their marital status, number of sex partners, sexual practices, history of STIs, sex frequency and condom use. Results Data showed a 24% dropped in the CT infection rate between 2007 and 2010, followed by a 14% increase in 2011. The HIV infection rates for the same period were between 15% and 16%. The risk of a CT-positive subject getting HIV is about 0.71 times the risk of a CT-negative subject. Young adult aged between 18 and 35 years old represented 65.2% of people who had STIs. 80% of women and 66% of men confessed to an inconsistent use of condoms. 11.6% of women and 48% of men declared having multiple sex partners. 61% of questioned women and 67% of men declared knowing their HIV status. Conclusions In this Gabonese setting, the population-aged from18 to 35 years is the most affected by STIs. Other matters of concern are the inconsistent use of protection and sex with non-spousal or non-life partners. PMID:24594663

    A cross-sectional sample of 3136 scalp hair drawn from 392 individuals aged 10 to 60 years and belonging to the Bania (n = 201) and Brahmin (n = 191) caste groups of Punjab State of India were examined for diameters of hair shaft and medulla, scale count, medulla type, hair index, medullary index and scale-count index, employing standard procedures. The mean hair shaft diameter, medullary diameter, incidence of medullation and scale-count index was higher in males, while the mean scale count was higher in females. However, with a few exceptions, the gender differences were not statistically significant (p < 0.05). The Brahmins showed significantly (p < 0.05) higher mean values of hair shaft diameter and scale count than the Banias. The mean scale-count index was higher among the Banias. The fragmentary medulla was the most common medullary type among the Banias, while the continuous medulla was the most frequent type of medulla among the Brahmins. The frequency of medullation was significantly more among the Banias. On the average, the hair shaft diameter and diameter of medulla increased up to 30 years. Some age variations in medullation were noticed in both the caste groups. No clear age trend was noticeable in the scale count. By and large, the mean hair shaft diameter of the Banias was less than that of other populations. The mean hair shaft diameter of the Brahmin males was greater than that of the Banias, the Onges, and the Bengalees. The Brahmin females showed greater mean hair shaft diameter than that of the Banias, the Australian Aborigines, the Juangs and the Onges. Human scalp hair shows some age, gender and population variations in micro-morphological variables which have the potential of being useful for anthropological and forensic investigations.

    This study employs an intra-national and cross-national, prospective and longitudinal design to examine age, gender, region, and country variation in group mean-level continuity and individual-differences stability of emotional availability in child-mother dyads. Altogether, 220 Argentine, Italian, and U.S. American metropolitan and rural residence mothers and their daughters and sons were observed at home when children were 5 and 20 months of age. Similar patterns of continuity and discontinuity of emotional availability from 5 to 20 months were observed across regions and countries, but not between genders. Stability of emotional availability from 5 to 20 months was moderate and similar across genders, regions, and countries. Universal and gender-specific developmental processes in child-mother emotional availability as revealed in intra- and cross-national study are discussed. PMID:20824179

    There is growing evidence that cognitive and motor functions are interrelated and may rely on the development of the same cortical and subcortical neural structures. However, no study to date has examined the relationships between brain volume, cognitive ability, and motor ability in typically developing children. The NIH MRI Study of Normal Brain Development consists of a large, longitudinal database of structural MRI and performance measures from a battery of neuropsychological assessments from typically developing children. This dataset provides a unique opportunity to examine relationships between the brain and cognitive-motor abilities. A secondary analysis was conducted on data from 172 children between the ages of 6 to 13 years with up to 2 measurement occasions (initial testing and 2-year follow-up). Linear mixed effects modeling was employed to account for age and gender effects on the development of specific cortical and subcortical volumes as well as behavioral performance measures of interest. Above and beyond the effects of age and gender, significant relationships were found between general cognitive ability (IQ) and the volume of subcortical brain structures (cerebellum and caudate) as well as spatial working memory and the putamen. In addition, IQ was found to be related to global and frontal gray matter volume as well as parietal gray and white matter. At the behavioral level, general cognitive ability was also found to be related to visuomotor ability (pegboard) and executive function (spatial working memory). These results support the notion that cognition and motor skills may be fundamentally interrelated at both the levels of behavior and brain structure. PMID:21078402

    We established age- and gender-specific reference ranges for the 36 routine complete blood cell (CBC) and 57 cell population data (CPD) items in the Sysmex XN-2000 (Sysmex, Japan). In total, 280 peripheral blood samples were obtained from an equal number of healthy adults. Values for 36 routine items and 57 CPD items were obtained for each sample, and the results were categorized into six subgroups (N>39 in each subgroup) according to patient age (20-40, 41-60, and >60 yr) and gender (male and female), and compared with respect to age and gender differences. The majority of data items (22 of 36 routine CBC items and 44 of 57 CPD items) exhibited significant differences (P≤0.05) in their results with respect to age or gender, and several red cell-, lymphocyte-, and platelet-related data tended to decrease in women or older adults. These results provide a basis for establishing age- and gender-specific reference ranges for routine and CPD items in Sysmex XN-2000. Furthermore, these reference ranges could be used to determine clinical significance for new items of Sysmex XN-2000 in further studies. PMID:26915613

    Statement of the Problem Treatment with salivary substitutes and stimulation of salivary flow by either mechanical or pharmacologic methods has side effects and only provides symptomatic relief but no long-lasting results. Purpose To assess the effectiveness of extraoral transcutaneous electric nerve stimulation (TENS) as a mean of stimulating salivary function in healthy adult subjects; as well as to determine the gender and age-dependent changes in salivary flow rates of unstimulated and stimulated parotid saliva. Materials and Method Hundred patients were divided into two groups; Group I aged 20-40 and Group II aged ≥ 60 years. The TENS electrode pads were externally placed on the skin overlying the parotid glands. Unstimulated and stimulated parotid saliva was collected for 5 minutes each by using standardized collection techniques. Results Eighty seven of 100 subjects demonstrated increased salivary flow when stimulated via the TENS unit. Ten experienced no increase and 3 experienced a decrease. The mean unstimulated salivary flow rate was 0.01872 ml/min in Group I and 0.0088 ml/min in Group II. The mean stimulated salivary flow rate was 0.03084 ml/min (SD= 0.01248) in Group I, and 0.01556 ml/min (SD 0.0101) in Group II. After stimulation, the amount of salivary flow increased significantly in both groups (p< 0.001). Statistical comparison of the two groups revealed them to be significantly different (p< 0.001), with Group I producing more saliva. Gender-wise, no statistically significant difference was seen among the subjects in Group I (p = 0.148), and those in Group II (p= 0.448). Out of 12 subjects with 0 baseline flows, 7 continued to have no flow. Five subjects observed side effects, although minimal and transient. Conclusion The TENS unit was effective in increasing parotid gland salivary flow in healthy subjects. There was age-related but no gender-related variability in parotid salivary flow rate.

    Purpose: To determine the effect of prostate cancer therapy (surgery or external beam irradiation, or both or none) on the actuarial incidence of subsequent bladder cancer. Methods and Materials: The Surveillance, Epidemiology, and End Results registry from 1973 to 2005 was analyzed. Treatment was stratified as radiotherapy, surgery, both surgery and adjuvant radiation, and neither modality. Brachytherapy was excluded. Results: In all, 555,337 prostate carcinoma patients were identified; 124,141 patients were irradiated; 235,341 patients were treated surgically; 32,744 patients had both surgery and radiation; and 163,111 patients received neither modality. Bladder cancers were diagnosed in: 1,836 (1.48%) men who were irradiated (mean age, 69.4 years), 2,753 (1.09%) men who were treated surgically (mean age, 66.9 years); 683 (2.09%) men who received both modalities (mean age, 67.4 years), and 1,603 (0.98%) men who were treated with neither modality (mean age, 71.8 years). In each treatment cohort, Kaplan-Meier analyses showed that increasing age (by decade) was a significant predictor of developing bladder cancer (p < 0.0001). Incidence of bladder cancer was significantly different for either radiation or surgery alone versus no treatment, radiation versus surgery alone, and both surgery and radiation versus either modality alone (p < 0.0001). On multivariate analysis, age and irradiation were highly significant predictors of being diagnosed with bladder cancer. Conclusions: Following prostate cancer, increasing age and irradiation were highly significant predictors of being diagnosed with bladder cancer. While use of radiation increased the risk of bladder cancer compared to surgery alone or no treatment, the overall incidence of subsequent bladder cancer remained low. Routine bladder cancer surveillance is not warranted.

    This study examined two instruments measuring gender dysphoria within the multicenter study of the European Network for the Investigation of Gender Incongruence (ENIGI). The Utrecht Gender Dysphoria Scale (UGDS) and the Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults (GIDYQ-AA) were examined for their definitions of gender dysphoria and their psychometric properties, and evaluated for their congruence in assessing the construct. The sample of 318 participants consisted of 178 male-to-females (MtF) and 140 female-to-males (FtM) who were recruited from the four ENIGI gender clinics. Both instruments were significantly correlated in the group of MtFs. For the FtM group, there was a trend in the same direction but smaller. Gender dysphoria was found to be defined differently in the two instruments, which led to slightly different findings regarding the subgroups. The UGDS detected a difference between the subgroups of early and late onset of gender identity disorder in the group of MtFs, whereas the GIDYQ-AA did not. For the FtM group, no significant effect of age of onset was found. Therefore, both instruments seem to capture not only similar but also different aspects of gender dysphoria. The UGDS focusses on bodily aspects, gender identity, and gender role, while the GIDYQ-AA addresses subjective, somatic, social, and sociolegal aspects. For future research, consistency in theory and definition of gender dysphoria is needed and should be in line with the DSM-5 diagnosis of gender dysphoria in adolescents and adults. PMID:26883025

    Based on cross-sectional data from the 2008 National Study of the Changing Workforce, this study investigates relationships between gender, age, and work-family conflict across 6 family life stages. Participants were 690 married/partnered employees who worked 35 or more hours a week. Results indicated a small but negative relationship between age and work-family conflict. Work-family conflict was also associated with family stage, with the least amount of conflict occurring during the empty nest stage and the most occurring when the youngest child in the home was 5 years of age or younger. Gender differences were also observed. Specifically, men reported more work interference with family than did women when the youngest child in the home was a teen. Women overall reported more family interference with work than did men. Results concerning age and gender revealed a different pattern demonstrating that family stage is not simply a proxy for age. Age had a main effect on work-to-family conflict that was monotonic in nature and on family to-work conflict that was linear in nature. In conclusion, the results indicate gender, age, and family stage each uniquely relate to work-family conflict. PMID:24885688

    Despite the importance of early detection to signal lifesaving treatment initiation for HIV+ infants, early infant diagnosis (EID) services have received considerably less attention than other aspects of prevention of mother to child transmission care. This study draws on baseline data from an on-going cluster randomized study of an intervention to improve EID services at six government hospitals across Kenya. Two logistic regressions examined potential predictors of "on time" (infant ≤6 weeks of age) vs. "late" (≥7 weeks) and "on time" versus "very late" (≥12 weeks) EID engagement among 756 mother-infant pairs. A quarter of the infants failed to get "on time" testing. Predictors of "on time" testing included being informed about EID by providers when pregnant, perceiving less HIV stigma, and mother's level of education. Predictors of "very late" testing (≥12 weeks of age) included not being informed about EID by providers when pregnant and living farther from services. Findings highlight the importance of ensuring that health care providers actively and repeatedly inform HIV+ mothers of the availability of EID services, reduce stigma by frequently communicating judgment free support, and assisting mothers in early planning for accessing EID services. Extra care should be focused on engaging mothers with less formal education who are at increased risk for seeking "late" EID testing. This study offers clear targets for improving services so that all HIV-exposed infants can be properly engaged in EID services, thus increasing the potential for the best possible outcomes for this vulnerable population.

    The association between timing of complementary food introduction and age at diagnosis of type 1 diabetes was investigated among 1077 children in the SEARCH for Diabetes in Youth study. Age at diagnosis was 5-month earlier for children introduced to sugar-sweetened beverages (SSB) in the first 12 months of life compared to those who were not (9.0 ± 0.2 vs. 9.5 ± 0.1; p=0.02), independent of HLA-risk status. Analyses stratified by HLA-risk status found that children with a high risk HLA genotype had an earlier age at diagnosis if they were introduced to fruit juice in the first year of life (mean age of diagnosis=9.3 ± 0.1, 9.1 ± 0.1 and 9.6 ± 0.2 for introduction at ≤ 6 months, between 7 and 11 months, and ≤12 months, respectively; p=0.04). Introduction of SSB in the first year of life may accelerate onset of type 1 diabetes independent of HLA-risk status. PMID:25117987

Age at diagnosis was 5 months earlier for children introduced to sugar-sweetened beverages (SSB) in the first 12 months of life compared with those who were not (9.0±0.2 vs 9.5±0.1; P=0.02) independent of human leukocyte antigen (HLA) risk status. Analyses stratified by HLA risk status found that children with a high-risk HLA genotype had an earlier age at diagnosis if they were introduced to fruit juice in the first year of life (mean age at diagnosis=9.3±0.1, 9.1±0.1 and 9.6±0.2 for introduction at ⩽6 months, between 7 and 11 months and ⩾12 months, respectively; P=0.04). Introduction of SSB in the first year of life may accelerate the onset of type 1 diabetes independent of HLA risk status. PMID:25117987

    Two modes of inheritance have been proposed in autism spectrum disorder, transmission though pre-existing variants and de novo mutations. Different modes may lead to different symptom expressions in affected individuals. De novo mutations become more likely with advancing paternal age suggesting that paternal age may predict phenotypic…
