There has been increasing interest in the impact of information and communication technologies, such as the computer and Internet, on physical and mental health status, but relatively little is known about the health effects of using cell phones. This study investigates how cell phone usage is associated with levels of depressive symptoms among Japanese men and women aged 65 years and older. We focus on social relationships, particularly intergenerational relationships between older parents and adult children, as a possible mediator in the association of cell phone use with late-life depressive symptoms. We therefore hypothesize that using cell phones contributes to the psychological well-being of older adults primarily through encouraging social relationships. We used 4 waves of data from the Nihon University Japanese Longitudinal Study of Aging (2001-2009) to analyze the impact of cell phone use on depressive symptoms. RESULTS are based on ordinary least squares regression analyses. Although the use of cell phones was related to lower levels of depressive symptoms among elderly Japanese people, controlling for sociodemographic characteristics and physical health conditions wiped out the effects for men. In contrast, the protective effects of using cell phones persisted among women, even net of all controls. Moreover, the impact of using cell phones was not explained by filial relationship measures, suggesting that cell phone use influences the mental health of older women independently of social engagement. Among the many advantages brought about by recent technological developments, cell phones appear to be an important contributor to the psychological well-being of Japanese elders. Researchers and policy makers should prioritize access to new technologies for older adults. © 2014 S. Karger AG, Basel.

The elderly are known to have an inadequate immune response to influenza vaccine. Mekabu fucoidan (MF), a sulfated polysaccharide extracted from seaweed, was previously shown to have an immunomodulatory effect. We therefore investigated antibody production after influenza vaccination in elderly Japanese men and women with and without oral MF intake. A randomized, placebo-controlled, double-blind study was conducted with 70 volunteers >60 y of age. They were randomly assigned to 1 of 2 groups, consuming either MF (300 mg/d) or placebo for 4 wk, and then given a trivalent seasonal influenza vaccine. Serum was sampled at 5 and 20 wk after vaccination to measure the hemagglutination inhibition titer and natural killer cell activity. The MF group had higher antibody titers against all 3 strains contained in the seasonal influenza virus vaccine than the placebo group. Titers against the B/Brisbane/60/2008 (B) strain increased substantially more in the MF group than in the placebo group over the product consumption period. The immune response against B antigen met the European Union Licensure criteria regarding the geometric mean titer ratio in the MF group (2.4), but not in the placebo group (1.7). In the MF group, natural killer cell activity tended to increase from baseline 9 wk after MF intake (P = 0.08). However, in the placebo group no substantial increase was noted at 9 wk, and the activity decreased substantially from 9 to 24 wk. In the immunocompromised elderly, MF intake increased antibody production after vaccination, possibly preventing influenza epidemics. PMID:24005608

Bacterial Pneumonia in Elderly Japanese Populations

Bacterial pneumonia is one of the most important infectious diseases in terms of incidence, effect on quality of life, mortality, and impact on society. Pneumonia was the third leading cause of death in Japan in 2011. In 2016, 119 650 Japanese people died of pneumonia, 96% of whom were aged 65 years and above. The symptoms of pneumonia in elderly people are often atypical. Aspiration pneumonia is seen more frequently than in young people because of swallowing dysfunction in the elderly. The mortality rate is also higher in the elderly than in young people. In Japan, the population is aging at an unprecedented rate, and pneumonia in the elderly will be increasingly important in medicine and medical economics in the future. To manage pneumonia in the elderly, it is important to accurately evaluate its severity, administer appropriate antibiotic treatment, and implement effective preventive measures. PMID:29434484

Elder Care, Multiple Role Involvement, and Well-Being Among Middle-Aged Men and Women in Japan.

Japan's population is aging at an unprecedented rate. Combined with the tradition of family responsibility for elder care, this rapid population aging has resulted in middle-aged Japanese people being much more likely today than in past decades to face the responsibility of caring for their elderly parents alongside their other major roles. Using nationally representative Japanese data, this study assessed the individual and combined implications of caregiving and other role involvements for the well-being of middle-aged men and women. Some evidence was found for deleterious psychological consequences of the caregiver role. However, in contrast to expectations, the interaction between the roles of caregiver and worker was positively associated with well-being among both men and women. The results suggest the importance of middle-aged adults being able to keep working when they have to care for their aging parents. Another important finding was significant gender differences in the psychological consequences of holding multiple family- and work-related roles and in combining these with the caregiver role. Further analysis showed that the spousal role was also negatively associated with depressive symptoms and positively associated with satisfaction for men but not for women. Gender differences in the findings appear to reflect the significant gender asymmetry in role experiences in Japan.

The purposes of this study were to identify 1) the feasibility of a novel exercise protocol (elderly Japanese male version of high-intensity interval aerobic training: EJ-HIAT) and 2) its preliminary data (%V̇O 2peak , rating of perceived exertion) in comparison with traditional moderate-intensity continuous aerobic training (MICT). Twenty-one sedentary elderly men, aged 60-69 years, performed two exercise protocols: EJ-HIAT, consisting of 3 sets of 2-3-min cycling at 75-85%V̇O 2peak with 1-2-min active rests at 50%V̇O 2peak between sets, and MICT, consisting of 40-min cycling at 65%V̇O 2peak . The completion rate, defined as the rate of participants who 1) did not demand withdrawal, 2) were not interrupted by the tester, and 3) did not change the workload during either exercise protocol, of EJ-HIAT was similar to that of MICT (EJ-HIAT: 100%, MICT: 95.2%). Maximal perceived exertion ratings assessed by Borg scale were also similar between EJ-HIAT and MICT. However, objectively measured maximal intensity assessed by %V̇O 2peak was higher for EJ-HIAT than for MICT (EJ-HIAT: 86.0 ± 5.6%, MICT: 67.1 ± 6.4%). These results suggested that EJ-HIAT has good feasibility and perceived exertion similar to MICT despite having higher objectively measured intensity than MICT. An intervention aimed as identifying the effects of EJ-HIAT on exercise tolerance should be performed in the future. UMIN000021185 (February 26, 2016).

The forced oscillation technique (FOT) can measure respiratory system resistance and reactance under tidal volume respiration. MostGraph is a device that incorporates the FOT and enables the immediate, three-dimensional visualization of resistance and reactance parameters. The aim of this study was to establish MostGraph reference values for middle-aged and elderly Japanese individuals. From 2004 to 2006, 3253 subjects living in Takahata, Yamagata underwent spirometry. Of these, 872 again underwent spirometry in 2011, and 784 (368 men, ages 46-89 years; 416 women, ages 47-90 years) underwent FOT examinations using MostGraph-01. In this study population, 19.0% of the men and 91.5% of the women were life-long never smokers. Abnormal spirometric findings were observed in 30.2% of the men and 14.6% of the women. Although the respiratory system resistance and reactance parameters obtained using MostGraph were not distributed normally, normal distribution was achieved via natural logarithm (R5, R20, Fres, and ALX), square root (R5-R20), or exponential (X5) transformation. Furthermore, the transformed values were converted back to the actual values after determining the values representing one and two standard deviations from the mean. Respiratory system resistance and reactance reference values were determined using MostGraph in middle-aged and elderly Japanese individuals who participated in annual health checkups.

Serum adiponectin levels are associated with frailty and cardiovascular diseases. Longitudinal changes in adiponectin levels might enhance our understanding of age-related conditions and diseases. This prospective observational study aimed to: (1) elucidate age-related changes in high-molecular-weight (HMW) adiponectin levels; and (2) identify variables predictive of elevated HMW adiponectin levels and the association with well-known adiponectin single-nucleotide polymorphisms (SNPs) in healthy, elderly Japanese participants. Healthy elderly volunteers (n = 196; 55 men and 141 women; median age 72.0 years; range 69.0-75.0 years) underwent anthropometric and physical function measurements, as well as laboratory tests at baseline and the 5-year follow-up. HMW adiponectin levels were significantly higher in women than in men (8.4, 5.3-11.9 vs. 5.7, 3.1-9.0 μg/mL; p < 0.001) at baseline and decreased significantly at follow-up in women (7.7, 4.8-11.2 μg/mL; p < 0.001), but not in men. In the multiple regression analysis, high-density lipoprotein cholesterol levels and body weight were independent predictors of HMW adiponectin levels. The rate of change in HMW adiponectin levels was inversely correlated with the rates of change in body weight, body mass index, and knee leg extension strengths, and positively correlated with rates of change in high-density lipoprotein cholesterol and one-leg standing time. There were no significant differences in HMW adiponectin levels among SNPs. Decreasing HMW adiponectin levels might lead to an increased risk of cardiovascular diseases in elderly women. HMW adiponectin levels significantly decreased over a 5-year period in community-dwelling elderly Japanese women.

[Psychodynamic hypothesis about suicidality in elderly men].

PubMed

Lindner, Reinhard

2010-08-01

Old men are overrepresented in the whole of all suicides. In contrast, only very few elderly men find their way to specialised treatment facilities. Elderly accept psychotherapy more rarely than younger persons. Therefore presentations on the psychodynamics of suicidality in old men are rare and mostly casuistical. By means of a stepwise reconstructable qualitative case comparison of five randomly chosen elderly suicidal men with ideal types of suicidal (younger) men concerning biography, suicidal symptoms and transference, psychodynamic hypothesis of suicidality in elderly men are developed. All patients came into psychotherapy in a specialised academic out-patient clinic for psychodynamic treatment of acute and chronic suicidality. The five elderly suicidal men predominantly were living in long-term, conflictuous sexual relationships and also had ambivalent relationships to their children. Suicidality in old age refers to lifelong existing intrapsychic conflicts, concerning (male) identity, self-esteem and a core conflict between fusion and separation wishes. The body gets a central role in suicidal experiences, being a defensive instance modified by age and/or physical illness, which brings up to consciousness aggressive and envious impulses, but also feelings of emptiness and insecurity, which have to be warded off again by projection into the body. In transference relationships there are on the one hand the regular transference, on the other hand an age specific turned around transference, with their counter transference reactions. The chosen methodological approach serves the systematic finding of hypotheses with a higher degree in evidence than hypotheses generated from single case studies.

This paper presents an ergonomic garment design for elderly Turkish men. The purpose of this study was to determine elderly men's demands, needs and problems in regard to clothing and to design an ergonomic garment in the light of this knowledge. The sample consisted of 120 elderly men living in Ankara, the capital city of Turkey, and its province. A questionnaire was prepared and given to these people in order to determine their clothing demands and needs. It was established that most of our subjects need functional garments. An ergonomic garment has been designed using the obtained data. It was found that the design of clothing for the elderly requires attention to bodily changes from aging in order to facilitate and raise the quality of life. Specific suggestions are made to elderly people and to the ready-to-wear sector.

Background The number of studies that use objective and quantitative methods to evaluate facial skin aging in elderly people is extremely limited, especially in Japan. Therefore, in this cross-sectional study we attempted to characterize the condition of facial skin (hyperpigmentation, pores, texture, and wrinkling) in Japanese adults aged 65 years or older by using objective and quantitative imaging methods. In addition, we aimed to identify lifestyle factors significantly associated with these visible signs of aging. Methods The study subjects were 802 community-dwelling Japanese men and women aged at least 65 years and living in the town of Kurabuchi (Takasaki City, Gunma Prefecture, Japan), a mountain community with a population of approximately 4800. The facial skin condition of subjects was assessed quantitatively using a standardized facial imaging system and subsequent computer image analysis. Lifestyle information was collected using a structured questionnaire. The association between skin condition and lifestyle factors was examined using multivariable regression analysis. Results Among women, the mean values for facial texture, hyperpigmentation, and pores were generally lower than those among age-matched men. There was no significant difference between sexes in the severity of facial wrinkling. Older age was associated with worse skin condition among women only. After adjusting for age, smoking status and topical sun protection were significantly associated with skin condition among both men and women. Conclusions Our study revealed significant differences between sexes in the severity of hyperpigmentation, texture, and pores, but not wrinkling. Smoking status and topical sun protection were significantly associated with signs of visible skin aging in this study population. PMID:19700917

This paper assesses the suicide of elderly men in Brazil. The text is based on studies of gender and masculinity and emphasizes the sense of "hegemonic masculinity" within the logic of patriarchalism that, in the case of suicide, is expressed in the loss of employment as an existential reference and as a loss of honor. The study includes 40 cases of men over 60 who committed suicide between 2007 and 2010 in ten districts of the country. Using the psychosocial autopsy technique, data were collected and analyzed from their history and lifestyle; evaluation of the background to the act; the impact on their families; lethality of the method; proximity to sources of support; previous attempts; mental status which preceded the act; reaction of families and communities. Although many factors are associated with self-inflicted death in this social group, the influence of a hegemonic masculinity culture in the predominance of suicides among elderly men compared with elderly women is undeniable. It is essential to give special attention to men at the moment of transition from working life to retirement, loss or important family members, and when they are diagnosed with chronic and degenerative diseases that cause disabilities, loss of autonomy or sexual impotence.

Cheilitis glandularis (CG) is a rare disorder characterized by swelling of the lip with hyperplasia of the labial salivary glands. CG is most frequently encountered in the lower lip, in middle-aged to older Caucasian men; however Asian cases were rarely reported. In this paper we present two cases of CG in Asian-Japanese men. One was a 23-year-old male with CG of the superficial suppurative type. The other was a 54-year-old male with deep suppurative type. We also reviewed the Japanese cases of CG in the literature and discussed about clinical feature of Japanese CG. PMID:21991474

Gender differences of social interactions and their effects on subjective well-being among Japanese elders.

Gender differences of social interactions and their effects on subjective well-being among Japanese elders over three years were examined. Repeated measurements of 498 elders over a three-year survey interval were obtained from a baseline mail survey and two- and three-year follow-up surveys. Outcomes were analyzed using Hierarchical Linear Modeling. Male elders were more likely to have a spouse and work at paid jobs, while female elders were likely to have more frequent contacts with their child/children and more interactions with friends. As the elders aged over three years, life satisfaction decreased, while depression did not show any significant overall trend. There were no beneficial effects of social interactions on change in well-being, although social participation, interaction with friends, and conversation with spouse were beneficially related to baseline levels of both depressive tendency and life satisfaction. Among female elders only, the number of children had beneficial effects on life satisfaction. There are modest gender differences of the impact of social interactions on the well-being of Japanese elders, and the number of children seems to be more important as potential sources of support for female rather than male elders. Spousal conversation and non-obligatory social interaction such as unpaid social activities and friendship seem to be important for both male and female elders in Japan. These findings suggest that social relations among Japanese elders may be moving away from more gender dependent patterns seen in the past.

Explanations for the low prevalence of atherosclerosis in Japan versus United States are often confounded with genetic variation. To help remove such confounding, coronary artery calcification (CAC), a marker of subclinical atherosclerosis, was compared between Japanese men in Japan and Japanese men in Hawaii. Findings are based on risk factor and CAC measurements that were made from 2001 to 2005 in 311 men in Japan and 300 men in Hawaii. Men were aged 40 to 50 years and without cardiovascular disease. After age-adjustment, there was a 3-fold excess in the odds of prevalent CAC scores ≥10 in Hawaii versus Japan (relative odds [RO] = 3.2; 95% confidence interval [CI] = 2.1,4.9). While men in Hawaii had a generally poorer risk factor profile, men in Japan were 4-times more likely to smoke cigarettes (49.5 vs. 12.7%, p<0.001). In spite of marked risk factor differences between the samples, none of the risk factors provided an explanation for the low amounts of CAC in Japan. After risk factor adjustment, the RO of CAC scores ≥10 in Hawaii versus Japan was 4.0 (95% CI = 2.2,7.4). Further studies are needed to identify factors that offer protection against atherosclerosis in Japanese men in Japan. PMID:17728270

A decline in physical activity has been shown to be associated with metabolic syndrome (MetS), leading to cardiovascular events. However, this is difficult to manage well in the elderly with multiple atherosclerotic risk factors. In this study, we investigated the correlation between physical activity and clinical parameters in the presence and absence of MetS in Japanese elderly subjects with type 2 diabetes mellitus (T2DM). In addition, we determined which factor, calorie intake or physical activity, mainly contributes to the prevalence of MetS. Cross-sectional analysis of 846 consecutive Japanese elderly (408 men and 438 women, mean age 68.7 years) was carried out at the time of enrolment (2000-2002) in the Japanese Elderly Diabetes Intervention Trial. Their level of physical activity was evaluated using the Baecke questionnaire, consisting of three components: work, sports and leisure. Total activity score (TAS) as the sum of each activity score was divided into four quartiles (Q1 to Q4). After adjustment for age and sex, there was a positive association of TAS with high-density lipoprotein cholesterol, although no significant correlation between other lipid parameters and TAS was found. In addition, fasting plasma glucose, insulin level and physical measurements, such as waist circumference, waist/hip ratio and body mass index, were inversely associated with TAS. Although no correlation between TAS and cognitive function Mini-Mental State Examination was found, TAS was positively associated with instrumental ADL and negatively associated with geriatric depression score (GDS), suggesting that a decline in physical activity in the elderly is associated with depressed mood rather than a decline of cognitive function. Total calorie intake appeared to increase according to TAS; however, this did not reach statistical significance. In a subanalysis comparing the presence and absence of MetS, the TAS grade in the MetS group was significantly lower than that in the

This subgroup analysis of STELLA-LONG TERM interim data explored the long-term safety and efficacy of ipragliflozin in non-elderly vs. elderly Japanese type 2 diabetes mellitus (T2DM) patients. STELLA-LONG TERM is an ongoing 3-year prospective surveillance study of Japanese T2DM patients receiving ipragliflozin 50 mg once daily. In this subgroup analysis, patient characteristics, laboratory variables, and adverse drug reactions (ADRs) were compared between non-elderly (<65 years) and elderly (≥65 years) patients. Non-elderly patients had significantly higher body mass index and low-density lipoprotein cholesterol than elderly patients (P < 0.001). The proportion of patients with hemoglobin A1c (HbA1c) <8.0% was significantly higher among elderly patients (P < 0.001). HbA1c, fasting plasma glucose, and body weight significantly decreased from baseline to 3 and 12 months in both groups (all P < 0.05 vs. baseline). The ADR incidence was 10.83% vs. 10.42% in non-elderly and elderly patients. The incidence of skin complications was 0.98% vs. 1.65% and that of renal disorder was 0.47% vs. 0.95% in non-elderly and elderly patients (both P = 0.003). Ipragliflozin was effective in non-elderly and elderly Japanese T2DM patients in a real-world clinical setting. The incidence of renal disorder and skin complications was significantly higher in elderly vs. non-elderly patients.

A decline in hypothalamic-pituitary-gonadal (HPG) axis function is often seen in elderly men, and dysthymic disorder is common. Symptoms of both HPG axis hypofunction and dysthymic disorder include dysphoria, fatigue, and low libido. The authors compared total testosterone levels in three groups of elderly men. Total testosterone levels were measured in subjects who met DSM-IV criteria for major depressive disorder (N=13) or dysthymic disorder (N=32) and a comparison group (N=175) who had participated in an epidemiological study of male aging and had scored below the median on the Center for Epidemiologic Studies Depression Scale, a well-validated, self-report depression symptom inventory. There were no differences among the three groups in measured demographic variables, including age and weight. Median testosterone levels varied for those with dysthymic disorder (295 ng/dl), major depressive disorder (425 ng/dl), and no depression (423 ng/dl). A test for differences in central tendency showed a statistically significant difference among the three groups. Post hoc pairwise comparisons revealed statistically significant differences between those with dysthymic disorder and those with major depressive disorder and no depression. Total testosterone levels were lower in elderly men with dysthymic disorder than in men with major depressive disorder and men without depressive symptoms. Dysthymic disorder in elderly men may be related to HPG axis hypofunction.

Sexual function and practice in elderly men of lower socioeconomic status.

Normal aging plus certain prevalent diseases are believed to render many elderly men impotent. Recent studies have suggested that educated middle-class and upper-class elderly men continue sexual activity, despite erectile dysfunction, by employing alternative practices such as mutual masturbation and oral sex. Few elderly men of lower socioeconomic background have been included in these studies, however. Using physician-administered interviews, 87 men attending an urban Veterans Administration geriatric clinic were studied to determine (1) the prevalence of erectile dysfunction, and (2) the sexual practices and attitudes of this group. Of the 87 men, 28% reported complete loss of erectile function, while 31% had frequent difficulties achieving vaginal intromission. Unlike economically advantaged groups, only 29% used mutual masturbation and 16% used oral sex. Attitudes toward these practices were negative. With one exception, men unable to perform coitus ceased all heterosexual activities.

Kosberg, Jordan I

2014-01-01

From research findings and practice experiences, it is concluded that abuse of older men is especially invisible and underreported, compared to abuse of older women. It is proposed that attention should be directed not to gender, but to those conditions in different countries and cultures leading to abuse of both older men and women, including (but not limited to) economic problems, few alternatives to family care of the elderly, violence, changing characteristics of the family, ageism, and sexism. Advocates for the prevention of elder abuse should work together in combating, reducing, and eliminating the problem of elder abuse of both older men and older women.

[Purpose] To compare the toe flexor, hand grip and knee extensor strengths of young and elderly men, and to examine the association between toe flexor strength and physical activity or inactivity levels. [Subjects and Methods] Young (n=155, 18-23 years) and elderly (n=60, 65-88 years) men participated in this study. Toe flexor, hand grip, and knee extensor strength were measured. Physical activity (time spent standing/walking per day) and inactivity (time spent sitting per day) were assessed using a self-administered questionnaire. [Results] Toe flexor, hand grip, and knee extensor strength of the elderly men were significantly lower than those of the young men. Standing/walking and sitting times of the elderly men were lower than those of the young men. Toe flexor strength correlated with hand grip and knee extensor strength in both groups. In elderly men, toe flexor strength correlated with standing/walking time. In comparison to the young men's mean values, toe flexor strength was significantly lower than knee extensor and hand grip strength in the elderly group. [Conclusion] The results suggest that age-related reduction in toe flexor strength is greater than those of hand grip and knee extensor strengths. An early loss of toe flexor strength is likely associated with reduced physical activity in elderly men.

The prevalence of and the risk factors for abnormal anal cytology among Japanese men who have sex with men (MSM) who have human immunodeficiency virus (HIV) infection have not been fully investigated up to now. We conducted a nested case-control study of 81 HIV-infected Japanese MSM treated with antiretroviral therapy at a sexuality minority affirmative clinic between April 2010 and March 2011. Results showed that 41 (50.6%) of the 81 had normal anal cytology, 13 (16.0%) atypical squamous cells, 24 (29.6%) low-grade squamous intraepithelial lesions, and 3 (3.7%) high-grade squamous intraepithelial lesions. No carcinoma cases were seen. Multivariate analysis showed abnormal anal cytology to be associated with a history of genital condyloma (OR 4.19, p = .021). We concluded that abnormal anal cytology was common among HIV-infected Japanese MSM. Effective screening and management should be planned for precancerous anal lesions.

In Japan, there are no valid and reliable physical activity questionnaires for elderly people. In this study, we translated the Physical Activity Scale for the Elderly (PASE) into Japanese and assessed its validity and reliability. Three hundred and twenty-five healthy and elderly subjects over 65 years were enrolled. Concurrent validity was evaluated by Spearman's rank correlation coefficient between PASE scores and an accelerometer (waking steps and energy expenditure), a physical activity questionnaire for adults in general (the Japan Arteriosclerosis Longitudinal Study Physical Activity Questionnaire, JALSPAQ), grip strength, mid-thigh muscle area per bodyweight, static valance and bodyfat percentage. Reliability was evaluated by the test-retest method over a period of 3-4 weeks. The mean PASE score in this study was 114.9. The PASE score was significantly correlated with walking steps (rho = 0.17, P = 0.014), energy expenditure (rho = 0.16, P = 0.024), activity measured with the JALSPAQ (rho = 0.48, P < 0.001), mid-thigh muscle area per bodyweight (rho = 0.15, P = 0.006) and static balance (rho = 0.19, P = 0.001). The proportion of consistency in the response between the first and second surveys was adequately high. The intraclass correlation coefficient for the PASE score was 0.65. The Japanese version of PASE was shown to have acceptable validity and reliability. The PASE is useful to measure the physical activity of elderly people in Japan.

Although age-related decline in the useful field of view (UFOV) is well recognized as a risk factor for at-fault crash involvement in elderly drivers, there is still room to study its applicability to elderly Japanese drivers. In the current study, we thus examined the relationship between UFOV and at-fault crash history in an elderly Japanese population. We also explored whether potential factors that create awareness of reduced driving fitness could be a trigger for the self-regulation of driving in elderly drivers. We measured UFOV and at-fault crash history from 151 community-dwelling Japanese aged 60 years or older, and compared UFOV of at-fault crash-free and crash-involved drivers. We also measured self-evaluated driving style using a questionnaire. UFOV in crash-involved drivers was significantly lower than that in crash-free drivers. No significant difference was found in self-evaluated driving style between crash-free and crash-involved drivers. In addition, there was no significant association between UFOV and self-evaluated driving style. The present study showed that UFOV is a good predictor of at-fault crash risk in elderly Japanese drivers. Furthermore, our data imply that it might be difficult for elderly drivers to adopt appropriate driving strategies commensurate with their current driving competence. © 2014 Japan Geriatrics Society.

It is well known that a decline in physical activity is associated with lifestyle-related diseases including cardiovascular (CV) events. However, little is known about the association between physical activity and CV events in elderly patients, because recent accumulating reports have mainly dealt with middle-aged populations. In this study, we investigated the correlation between physical activity and CV events in Japanese elderly patients with type 2 diabetes mellitus (T2DM). A total of 938 Japanese elderly patients with T2DM (447 men and 491 women, mean age 71.9 years) enrolled (2000-2002) in the Japanese Elderly Diabetes Intervention Trial (J-EDIT) were used in this study. Physical activity consisting of three components, work, sports and leisure-time, of their lifestyle was evaluated using the Baecke questionnaire at baseline. Total activity score (TAS) as a sum of each activity score was divided into four quartiles (Q1 to Q4). During a follow-up period of 65.2 months, 165 events and 71 deaths in total occurred. Higher TAS grade was associated with reduced risk of all events (hazard ratios: 0.82, 0.77 and 0.54 in Q2, Q3 and Q4, respectively) with statistical significance. Even after multivariate adjustment for covariates, higher TAS grade was a strong predictor of all events, and the prediction by TAS of cerebrovascular events was more effective than that of cardiac events. In contrast, all-cause mortality gradually decreased according to TAS grade; however, no statistical significance was found. Among the four grades of TAS, no significant change in several parameters, such as profiles of lipid and glucose metabolism, blood pressure, physical measurements, cognitive function and depression scale, was found throughout the follow-up period, suggesting that the higher level of physical activity itself was associated with the risk reduction of primary events. Lower physical activity is a strong and independent predictor of all CV events in the elderly with T2DM

[Purpose] To compare the toe flexor, hand grip and knee extensor strengths of young and elderly men, and to examine the association between toe flexor strength and physical activity or inactivity levels. [Subjects and Methods] Young (n=155, 18–23 years) and elderly (n=60, 65–88 years) men participated in this study. Toe flexor, hand grip, and knee extensor strength were measured. Physical activity (time spent standing/walking per day) and inactivity (time spent sitting per day) were assessed using a self-administered questionnaire. [Results] Toe flexor, hand grip, and knee extensor strength of the elderly men were significantly lower than those of the young men. Standing/walking and sitting times of the elderly men were lower than those of the young men. Toe flexor strength correlated with hand grip and knee extensor strength in both groups. In elderly men, toe flexor strength correlated with standing/walking time. In comparison to the young men’s mean values, toe flexor strength was significantly lower than knee extensor and hand grip strength in the elderly group. [Conclusion] The results suggest that age-related reduction in toe flexor strength is greater than those of hand grip and knee extensor strengths. An early loss of toe flexor strength is likely associated with reduced physical activity in elderly men. PMID:27313353

Analyze the influence of sarcopenia in bone health of elderly men. This cross-sectional study evaluated 198 men aged over 60 years. Body composition was measured by dual energy X-ray absorptiometry. The BMD was measured at the femoral neck, total hip, lumbar spine and 33% radius. The diagnosis of abnormal BMD was defined for men who presented densitometric diagnosis of osteopenia or osteoporosis defined by T-score of femoral neck, total hip and lumbar spine. The pre-sarcopenia and sarcopenia were defined according to the European Working Group on Sarcopenia in Older People. The group diagnosed with normal BMD, compared to the group of abnormal BMD, have significantly higher body weight, body mass index, grip strength, lean mass, fat mass, and relative appendicular skeletal muscle mass (RASM). However, after multiple linear regression analysis, we found that only the RASM, lean mass, and handgrip strength in the dominant hand influenced the variability of the BMD after adjustment for age and weight. Regression analyzes showed a positive association between greater appendicular lean mass and a smaller number of elderly patients with abnormal BMD diagnostic. The regression analyzes showed that elderly men diagnosed with pre-sarcopenia and sarcopenia had more abnormal BMD than non-sarcopenic elderly men. We concluded that pre-sarcopenia and sarcopenia were associated with abnormal BMD. The lean mass, compared to fat mass, has a greater positive influence on the BMD of elderly men. This result suggests the importance of the increase in lean mass for the bone health of elderly men.

This cross-sectional study aimed to determine ethnic and environmental influences on the relationship between BMI and percentage body fat, using a sample of 144 Japanese and 140 Australian-Caucasian men living in Australia, and eighty-eight Japanese men living in Japan. Body composition was assessed by anthropometry using standard international methods (International Society for the Advancement of Kinanthropometry protocol). Body density was predicted using Durnin and Womersley's (1974) equation, and percentage body fat was calculated from Siri's (1961) equation. Significant (P<0.05) ethnic differences in stature, body mass and BMI were observed between Japanese and Australian men, but no ethnic differences were observed in their percentage body fat and height-corrected sum of skinfold thicknesses. No differences were found in the BMI-percentage body fat relationship between the Japanese subjects living in Australia and in Japan. Significant (P<0.05) ethnic differences in the BMI-percentage body fat relationship observed from a comparison between pooled Japanese men (aged 18-40 years, BMI range 16.6-32.8 kg/m2) and Australians (aged 18-39 years, BMI range 16.1-31.4 kg/m2) suggest that Japanese men are likely to have a greater percentage body fat than Australian men at any given BMI value. From the analyses, the Japanese men were estimated to have an equivalent amount of body fat to the Australian men at BMI values that were about 1.5 units lower than those of the Australians (23.5 kg/m2 and 28.2 kg/m2, respectively). It was concluded that Japanese men have greater body fat deposition than Australian-Caucasians at the same BMI value. Japanese men may therefore require lower BMI cut-off points to identify obese individuals compared with Australian-Caucasian men.

Study of immigrant populations may contribute to a better understanding of the epidemiology of diseases associated with the aging process. We examined the prevalence of cardiovascular risk factors, including apolipoprotein E (ApoE) polymorphism, in elderly subjects who were born in Japan, migrated to South Brazil and have lived in that region for over 40 years, versus a group of elderly, locally born Brazilians living in the same region. These Japanese subjects came to Brazil after World War II (1950-1960) from several Japanese cities, mainly Nagasaki, Kumamoto and Hokkaido. Among 1007 subjects genotyped for ApoE polymorphism, we selected 540 elderly subjects (>60 years old), consisting of 270 Japanese-Brazilians and 270 Brazilians of European ancestry from Rio Grande do Sul State (Gaucha population). The Japanese-Brazilian group had significantly lower prevalences of obesity, type 2 diabetes mellitus, dyslipidemia, and metabolic syndrome than did the Gaucho population group. ApoE polymorphism frequencies were similar in the two groups. The differences in cardiovascular risk factors observed in the two populations cannot be explained by ApoE polymorphism; they could be related to conservation of Japanese lifestyle habits, such as diet.

At the same level of BMI, white people have less visceral adipose tissue (VAT) and are less susceptible to developing type 2 diabetes than Japanese people. No previous population-based studies have compared insulin resistance and insulin secretion between these two races in a standardised manner that accounts for VAT. We compared HOMA-IR, HOMA of beta cell function (HOMA-β%) and disposition index (DI) in US white men and Japanese men in Japan. We conducted a population-based, cross-sectional study, comprising 298 white men and 294 Japanese men aged 40-49 years without diabetes. Insulin, glucose, VAT and other measurements were performed at the University of Pittsburgh. We used ANCOVA to compare geometric means of HOMA-IR, HOMA-β% and DI, adjusting for VAT and other covariates. White men had higher HOMA-IR, HOMA-β% and DI than Japanese men, and the difference remained significant (p < 0.01) after adjusting for VAT (geometric mean [95% CI]): 3.1 (2.9, 3.2) vs 2.5 (2.4, 2.6), 130.8 (124.6, 137.3) vs 86.7 (82.5, 91.0), and 42.4 (41.0, 44.0) vs 34.8 (33.6, 36.0), respectively. Moreover, HOMA-IR, HOMA-β% and DI were significantly higher in white men even after further adjustment for BMI, impaired fasting glucose and other risk factors. The higher VAT-adjusted DI in white men than Japanese men may partly explain lower susceptibility of white people than Japanese people to developing type 2 diabetes. The results, however, should be interpreted with caution because the assessment of insulin indices was made using fasting samples and adjustment was not made for baseline glucose tolerance. Further studies using formal methods to evaluate insulin indices are warranted.

The present study examined whether the three major functions of autobiographical memory observed in Western societies (i.e., directing-behaviour, social-bonding and self-continuity) also exist in an East Asian society. Two self-report measures were used to assess the autobiographical memory functions of Japanese men and women. Japanese young adults (N = 451, ages 17-28 years) first completed the original Thinking About Life Experiences (TALE) Questionnaire. They subsequently received three TALE items that represented memory functions and attempted to recall a specific instance of memory recall for each item. Confirmatory factor analyses on the TALE showed that the three functions were replicated in the current sample. However, Japanese participants reported lower levels of all three functions than American participants in a previous study. We also explored whether there was an effect of gender in this Japanese sample. Women reported higher levels of the self-continuity and social-bonding functions than men. Finally, participants recalled more specific instances of memory recall for the TALE items that had received higher ratings on the TALE, suggesting that the findings on the first measure were supported by the second measure. Results are discussed in relation to the functional approach to autobiographical memory in a cross-cultural context.

Group involvement and self-rated health among the Japanese elderly: an examination of bonding and bridging social capital

PubMed Central

2013-01-01

Background To date, only a small amount of research on bonding/bridging social capital has separately examined their effects on health though they have been thought to have differential effects on health outcomes. By using a large population-based sample of elderly Japanese people, we sought to investigate the association between bonding and bridging social capital and self-rated health for men and women separately. Methods In August 2010, questionnaires were sent to all residents aged ≥65 years in three municipalities in Okayama prefecture (n = 21232), and 13929 questionnaires were returned (response rate: 65.6%). Social capital was measured from survey responses to questions on participation in six different types of groups: a) the elderly club or sports/hobby/culture circle; b) alumni association; c) political campaign club; d) citizen’s group or environmental preservation activity; e) community association; and f) religious organization. Participant perception of group homogeneity (gender, age, and previous occupation) was used to divide social capital into bonding or bridging. Odds ratios (ORs) and 95% confidence intervals (CIs) for poor self-rated health were calculated. Results A total of 11146 subjects (4441 men and 6705 women) were available for the analysis. Among men, bonding and bridging social capital were inversely associated with poor self-rated health (high bonding social capital; OR: 0.55, 95% CI: 0.31–0.99; high bridging social capital; OR: 0.62, 95% CI: 0.48–0.81) after adjusting for age, educational attainment, smoking status, frequency of alcohol consumption, overweight, living arrangements, and type-D personality. The beneficial effect among women was more likely limited to bonding social capital (high bonding social capital; OR: 0.34, 95% CI: 0.12–1.00), and the association between bridging social capital and self-rated health was less clear (high bridging social capital; OR: 0.69, 95% CI: 0.44–1.07).

The present study aimed to determine the association of sarcopenia, defined by muscle mass, muscle strength and physical performance, with functional disability from a 2-year cohort study of community-dwelling elderly Japanese people. Participants were 743 community-dwelling elderly Japanese people aged 65 years or older. We used bioelectrical impedance analysis (BIA) to measure muscle mass, grip strength to measure muscle strength, and usual walking speed to measure physical performance in a baseline study. Functional disability was defined using an activities of daily living (ADL) scale and instrumental activities of daily living (IADL) scale at baseline and during follow-up examinations 2 years later. Logistic regression analysis, adjusted for age and body mass index, was used to examine the association between sarcopenia and the occurrence of functional disability. In the present study, 7.8% of men and 10.2% of women were classified as having sarcopenia. Among sarcopenia patients in the baseline study, 36.8% of men and 18.8% of women became dependent in ADL at 2-year follow up. From the logistic regression analysis adjusted by age and body mass index, sarcopenia was significantly associated with the occurrences of physical disability compared with normal subjects in both men and women. Sarcopenia, defined by muscle mass, muscle strength and physical performance, was associated with functional decline over a 2-year period in elderly Japanese. Interventions to prevent sarcopenia are very important to prevent functional decline among elderly individuals. © 2013 Japan Geriatrics Society.

The purpose of this study was to compare the effects of exercise habituation (3-32 years, mean 13.2 years) on physical vitality among five different groups. One hundred and two independent, community-dwelling elderly Japanese men, aged 64.6 +/- 6.6 years, were recruited as subjects. The vital age test battery consisted of various coronary heart disease risk factors and physical fitness elements. The results of analysis of variance revealed that vital age as an index of physical vitality was youngest in joggers (47.9 yr, N=18), intermediate in trekkers (55.8 yr, N=20) and walkers (59.1 yr, N=18), and oldest (69.6 yr, N=20) in patients with ischemic heart disease (IHD). The difference between chronological age and vital age was approximately 15 years (p<0.05) in joggers, and 8 years (p<0.05) in trekkers and walkers. The vital age of sedentary persons (N=26) was only 1.9 years (NS) younger than their chronological age, which was similar to the difference (vital age of 64.1 +/- 8.5 yr vs chronological age of 65.7 +/- 5.4 yr) previously observed in similarly aged exercising IHD patients. These results indicate that exercise habituation significantly affects the overall health status of most individuals, irrespective of mode of exercise. Among the three modes of exercise, jogging may be most beneficial. Furthermore, regularly exercising coronary patients may have physical vitality similar to that of sedentary men.

To investigate the potential benefits of testosterone administration to elderly men (>65 years) with late-onset hypogonadism (LOH) in comparison with younger men and to assess the safety of testosterone administration to elderly men. A total of 561 hypogonadal men from two registry studies were divided into age groups of ≤65 years (group Y, n=450; range, 32-65 years) and >65 years (group O, n=111; range, 66-84 years). Following an initial 6-week interval, all men were treated with 3-month injections of parenteral testosterone undecanoate for up to 6 years. Over the 6 years, there was a progressive decrease of body weight and waist circumference. Beneficial effects on lipids and other metabolic factors and on psychological and sexual functioning progressed over the first 24 to 42 months and were sustained. Rather than a deterioration, there was an improvement of urinary parameters. Prostate volume and prostate-specific antigen increased moderately. Hematocrit levels increased but remained within safe margins. The benefits of restoring serum testosterone in men with LOH were not significantly different between men older than 65 years of age and younger men. There were no indications that side effects were more severe in elderly men. The effects on prostate and urinary function and hematocrit were within safe margins. Age itself need not be a contraindication to testosterone treatment of elderly men with LOH.

Diabetic nephropathy is a serious complication in patients with type 2 diabetes. The aim of this study was to explore the factors associated with the progression of this complication in elderly patients with type 2 diabetes. This retrospective study of a subgroup of patients registered with the Japanese Elderly Diabetes Intervention Trial included 621 Japanese patients with type 2 diabetes mellitus (age ≥ 65 years, 346 with normoalbuminuria, 190 with microalbuminuria and 85 with overt proteinuria). Multivariate Cox proportional hazard regression model with a backward stepwise procedure was applied to select factors with significant effects on worsening of nephropathy stage and the doubling of serum creatinine. During the follow up (median 52 months), 21% of patients progressed from normoalbuminuria and microalbuminuria to a worse nephropathy stage. Aging, female sex and high-density lipoprotein cholesterol were identified as independent and significant factors that worsen nephropathy stage. Also, 6.1% of patients showed doubling of serum creatinine during follow up. A positive history of cardiovascular disease, hyperuricemia and conventional therapy were identified as significant factors involved in the doubling of serum creatinine. The cumulative incidence of the doubling of serum creatinine was significantly lower in the intensive therapy group than the conventional therapy group (P = 0.016), although that of progression of nephropathy stage was similar in the two groups. We identified several factors associated with the progression of diabetic nephropathy in elderly patients with type 2 diabetes. The results suggest that multiple risk factor intervention seems important in preventing deterioration of renal dysfunction. © 2012 Japan Geriatrics Society.

To investigate the relationship between diet and prostate cancer (CaP) among native Japanese (NJ) and second-generation or third-generation Japanese-American (J-A) men--focusing on the effects of animal fat and soy on prostatic tissues. The subjects were 50 Japanese men undergoing radical prostatectomy, 25 NJ living in Nagoya, Japan and 25 U.S.-born J-A men, living in Los Angeles, California. A priori, the NJ men were believed to be a low-fat, high-soy group and the J-A men, a high-fat, low-soy group. The studies included postoperative measurements of diet (Block questionnaire), body fat (bioimpedance), blood, urine, and prostatic biomarkers in malignant and adjacent normal tissue, using a tissue microarray made from the original paraffin blocks. The NJ and J-A men were similar in age (65 to 70 years old; P <0.05), prostate-specific antigen level (7.1 to 8.6 ng/mL), prostate volume (35 to 38 cm3), and Gleason score (5.6 to 6.6), but their body composition differed. J-A men had more body fat (24% versus 19%), higher serum triglyceride levels (245 versus 106 mg/dL), lower estradiol levels (27 versus 31 ng/mL), and much lower urinary soy-metabolite levels (1:3) than NJ men (P <0.02). In both NJ and J-A groups, expression of numerous tissue biomarkers separated normal from CaP tissue, including markers for apoptosis (Bcl-2, caspase-3), growth factor receptors (epidermal growth factor receptor), racemase, 5-lipoxygenase, kinase inhibition (p27), and cell proliferation (Ki-67; all P <0.02). Furthermore, within both normal and CaP tissues, caspase-3 and 5-lipoxygenase were expressed more in NJ than in J-A men (P <0.01). Nuclear morphometry showed that the chromatin in each of the four groups (normal versus CaP, NJ versus J-A) was different (area under the curve 85% to 94%, P <0.01), despite fundamental genetic homogeneity. NJ and J-A men, products of similar genetics but differing environments, were shown to have differences in body composition that could influence Ca

The incidence of coronary heart disease in the United States has declined, and prevalences of several coronary disease risk factors have become comparable to those in Japan. Therefore, the burden of coronary atherosclerosis may be closer among younger persons in the 2 countries. We aimed to compare prevalences of coronary atherosclerosis, measured with coronary artery calcium scores, between men in the 2 countries by age group (45–54, 55–64, or 65–74 years). We used community-based samples of Caucasian men in the United States (2000–2002; n = 1,067) and Japanese men in Japan (2006–2008; n = 832) aged 45–74 years, stratifying them into groups with 0, 1, 2, or ≥3 of the following risk factors: current smoking, overweight, diabetes, dyslipidemia, and hypertension. We calculated adjusted odds ratios of US Caucasian men's having Agatston scores of ≥10, ≥100, and ≥400 with reference to Japanese men. Overall, the odds of Caucasian men having each Agatston cutoff point were greater. The ethnic difference, however, became smaller in younger age groups. For example, adjusted odds ratios for Caucasian men's having an Agatston score of ≥100 were 2.05, 2.43, and 3.86 among those aged 45–54, 55–64, and 65–74 years, respectively. Caucasian men in the United States had a higher burden of coronary atherosclerosis than Japanese men, but the ethnic difference was smaller in younger age groups. PMID:25125689

Differing lifestyle, nutritional, and genetic factors may lead to a differing stiffness index (SI) determined by quantitative ultrasound in elderly men and women. The purpose of this study was to determine SI and the gender-specific factors associated with low SI in a Korean elderly cohort. This was a cross-sectional descriptive study identifying the gender-specific factors related to SI in 252 men and women aged 65 years and greater from local senior centers in Seoul, Korea between January and February 2009. The mean SI of elderly men was significantly higher than that of the women's. A multiple regression analysis reveals that age, nutritional status, and physical activity were predictive factors of lower SI in men, whereas age, alcohol consumption, educational level, and genetic polymorphism were predictive factors for elderly women. Low SI was common in both elderly men and women. We found gender differences in factors linked to low SI. In multiple regression analysis, nutritional status and physical activity were more important factors in men, whereas alcohol consumption, educational level, and genetic polymorphism were significant factors predicting low SI in women. Gender-specific modifiable risk factors associated with low SI should be considered when developing osteoporosis prevention programs for the elderly. Copyright © 2015. Published by Elsevier B.V.

Sarcopenia is a syndrome characterized by loss of skeletal muscle mass and function (strength and physical performance) with a risk of adverse outcomes. Asian criteria have been decided recently by the Asia Working Group for Sarcopenia (AWGS) . AWGS defined sarcopenia as low skeletal muscle mass plus low muscle strength and/or low physical performance based on the previous reports. AWGS recommend cutoff values for muscle mass (7.0 kg/m(2) for men and 5.4 kg/m(2) for women by using dual X-ray absorptiometry, and 7.0 kg/m(2) for men and 5.7 kg/m(2) for women by using bioelectrical impedance analysis) , handgrip strength (<26 kg for men and <18 kg for women) , and usual gait speed (<0.8 m/s) . The prevalence of sarcopenia in Japanese elderly men and women diagnosed using Asian criteria was 9.6% and 7.7%, respectively. The estimated number of prevalent cases of sarcopenia in Japanese elderly men and women was approximately 1.3 million and 1.4 million, respectively.

To determine the incidence of adverse drug reactions (ADRs) associated with ipragliflozin in elderly Japanese patients with type 2 diabetes mellitus. We report interim results of a postmarketing surveillance survey. Japanese physicians recorded ADRs in elderly patients (≥ 65 years old) who were first prescribed with ipragliflozin within 3 months of its launch (April 2014). Incidence of ADRs within 1 year of starting treatment with ipragliflozin. 898 ADRs occurred in 721/7,170 patients (10.06%). Skin complication-, volume depletion-, genital infection-, polyuria/pollakiuria-, urinary tract infection-, and hypoglycemia-related ADRs occurred in 2.23%, 1.90%, 1.45%, 1.32%, 0.77%, and 0.32%, respectively. ADRs were classified as serious in 44 (0.61%) patients. Half of the ADRs occurred within 30 days of starting treatment. There were no cases of Stevens-Johnson syndrome or toxic epidermal necrolysis. Most (92.1%) of the ADRs resolved or improved. Glycated hemoglobin, fasting blood glucose, body weight, and systolic blood pressure decreased by 0.6% (baseline 7.8%), 22.7 mg/dL (baseline 163.0 mg/dL), 2.3 kg (baseline 67.4 kg), and 3.1 mmHg (baseline 133.2 mmHg), respectively, from baseline to treatment discontinuation/last visit. Ipragliflozin is well tolerated and reduced surrogate endpoints in elderly Japanese patients with type 2 diabetes mellitus. Clinicaltrials.gov identifier: NCT02297620.

The effects of the prolonged elevation of nonesterified fatty acid (NEFA) levels on insulin secretion have been controversial and thought to be sex-specific. To investigate the association between a westernized lifestyle and the effects of NEFA on insulin secretion in Japanese men, we examined 67 nondiabetic Japanese-American men and 220 nondiabetic native Japanese men who underwent a 75-g oral glucose tolerance test (OGTT). Most Japanese Americans we surveyed are genetically identical to Japanese living in Japan, but their lifestyle is more westernized. Sets of multiple regression analyses were performed to evaluate the relationship between the sum of the immunoreactive insulin (IRI) levels during the OGTT ((Sigma)IRI) and clinical parameters. Japanese Americans had higher levels of fasting IRI, (Sigma)IRI, and a higher insulin resistance index (homeostasis model assessment for insulin resistance [HOMA-IR]) than native Japanese, whereas there were no significant differences in fasting NEFA and triglyceride levels. A multiple regression analysis adjusted for age, fasting triglycerides, and body mass index (BMI) demonstrated that the fasting NEFA level was an independent determinant of the (Sigma)IRI only in Japanese-American men ( P = .001), but not in native Japanese men ( P = .054). Even when HOMA-IR was included in models instead of BMI, the NEFA level was a significant variable of (Sigma)IRI only in Japanese Americans ( P < .001), and not in native Japanese ( P = .098). In addition, a multiple regression analysis adjusted for age, fasting triglycerides, and BMI demonstrated that the fasting NEFA level was the only independent determinant of (Sigma)C-peptide in Japanese-American men ( P = .041). In conclusion, NEFA seems to be associated with insulin secretion independent of obesity or HOMA-IR. A westernized lifestyle may increase the effects of serum fasting NEFA levels on total insulin secretion after a glucose load in Japanese men.

Use of vitamin supplements and the association with personal characteristics were investigated among 4,654 American men of Japanese ancestry in Hawaii. A total of 58 percent of the subjects who were ages 68 to 90 took vitamin supplements. Among supplement users, multivitamins were most commonly used (77 percent), followed by vitamin C (53 percent), E (43 percent), and A (10 percent). Ninety-two percent of users took at least seven pills per week when all types of pills were combined. Vitamin supplement users were more educated, more physically active, more likely to be married, and less obese than nonusers. They also slept less, smoked less, and drank less alcohol and caffeine. They took more analgesics and stomach medication and had fewer days of hospitalization in the previous 10 years compared with nonusers. Except for physical activity, use of stomach medicines, and hospitalization, the other characteristics were also positively correlated with the amount of vitamin pill intake. These findings indicate that vitamin supplement users have different health patterns compared with nonusers. PMID:1454984

The purpose of this study was to investigate the association between sarcopenia and mild cognitive impairment (MCI) in elderly patients with diabetes using the Japanese version of the simple 5-item questionnaire (SARC-F-J). Cross-sectional study. Community hospital in Japan. Subjects were people with diabetes aged 65 years and older being treated on an outpatient basis at the Ise Red Cross Hospital. We used the Japanese version of the self-administered cognitive test Test Your Memory (TYM-J) to measure MCI and the self-administered questionnaire SARC-F-J, consisting of 5 items, to evaluate sarcopenia. We conducted a multiple logistic regression analysis with MCI as the dependent variable and sarcopenia as the explanatory variable to calculate the odds ratio of sarcopenia in association with MCI. A total of 250 cases (150 men and 100 women) were included in our study. The prevalence of sarcopenia in this sample was 19.5% and that of MCI was 40.3%. The adjusted odds ratio of sarcopenia in association with MCI was 2.96 (95% confidence interval, 1.09-7.70, P = .032). A statistically significant association was found between sarcopenia and MCI in an assessment of elderly patients with diabetes using the SARC-F-J.

To determine the relationship between body mass index and prostate cancer risk at biopsy in Japanese men, and to compared the risk with that of Caucasian men. We retrospectively evaluated 3966 men with prostate-specific antigen levels from 2.5 to 19.9 ng/mL who underwent an initial extended prostate biopsy. Using logistic regression, odds ratios of each body mass index category for risk of prostate cancer and high-grade disease (Gleason score ≥4 + 3) were estimated after controlling for age, prostate-specific antigen, %free prostate-specific antigen, prostate volume, digital rectal examination findings, family history of prostate cancer and the number of biopsy cores. Patients were divided into six categories according to their body mass index (kg/m(2) ) as follows: <21.0, 21.0-22.9, 23.0-24.9, 25.0-26.9, 27.0-29.9 and ≥30.0. A significant positive association was observed between body mass index and prostate cancer risk at biopsy, with an increased risk observed in men whose body mass index was ≥27.0 compared with the reference group. A significantly increased risk starting at body mass index ≥25.0 was found in high-grade disease. In contrast to our results, there has been no reported increase in the risk of prostate cancer at biopsy in Caucasians within the overweight range (body mass index of 25.0-29.9 based on World Health Organization classification). Japanese men within the overweight body mass index range who have an elevated prostate-specific antigen level also have a significant risk of harboring prostate cancer, especially high-grade disease. Overweight Japanese might be at greater prostate cancer risk at biopsy than overweight Caucasians. © 2012 The Japanese Urological Association.

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

Coronary heart disease (CHD) incidence and mortality remain very low in Japan despite major dietary changes and increases in CHD risk factors that should have resulted in substantial increase in CHD rates (Japanese paradox). Primary genetic effects are unlikely, given the substantial increase in CHD in migrant Japanese to the U.S. For men aged 40–49, levels of total cholesterol and blood pressure have been similar in Japan and the U.S. throughout their lifetime. The authors tested the hypothesis that levels of subclinical atherosclerosis, coronary artery calcification and intima-media thickness of the carotid artery (IMT), in men aged 40–49 are similar in Japan and the U.S. The authors conducted a population-based study of 493 randomly-selected men: 250 men in Kusatsu, Shiga, Japan, and 243 white men in Allegheny County, Pennsylvania, U.S. in 2002–2005. The Japanese had a less favorable profile of many risk factors than the whites. Prevalence ratio for the presence of coronary calcium score ≥10 in the Japanese compared to the whites was 0.52 (95% CI, 0.35, 0.76). Mean (SE) IMT was significantly lower in the Japanese (0.616 (0.005) versus 0.672 (0.005) mm, p<0.01). Both associations remained significant after adjusting for risk factors. The findings warrant further investigations. PMID:17244636

To research the demographic and clinical profiles of elderly Japanese emigrants, who arrived in Brazil before World War II, in order to give them appropriate psychogeriatric care. Elderly Japanese immigrants aged 65 years and over, belonging to the Miyagi Association in the São Paulo Metropolitan Area, were targeted. They emigrated from Miyagi Prefecture to Brazil and are now living in the area. We were able to interview 166 respondents. All data were gathered using standardized interview methods covering (a) free interview about the immigration history, (b) demographics, and (c) physical status. Through the free interview, we found their immigration histories, which affected their clinical profiles. The mean age and educational level were 77.5 years and 6.3 years, respectively. Sixty per cent of them immigrated when they were younger than 14. Ninety-four per cent of them still keep Japanese nationality. Fifty-seven per cent of them usually use Japanese, while 10% of them use Portuguese. Although their emigration histories were hard, 76% of them perceived their health as being excellent or relatively good. The percentages of subjects with histories of disease were hypertension, 52.5%; cardiac disease, 20.8%; diabetes mellitus, 24.2%; and hyperlipidemia, 25.0%, which were affected by the Brazilian environment. The elderly Japanese who emigrated to Brazil before World War II have a unique historical and demographic background. Their clinical profiles cannot be fully understood without knowing their histories. They definitely need high quality international psychogeriatric care. Copyright 2001 John Wiley & Sons, Ltd.

How accurate are self-reported height, weight, and BMI among community-dwelling elderly Japanese?: Evidence from a national population-based study.

The aims of this study are to investigate the accuracy of self-reported height, weight, and derived BMI of community-dwelling Japanese aged 70 and older, and to assess the concordance between report-based and measurement-based BMI categories. We compared self-reported height and weight with physical measurements from data from a nationally representative sample (n = 1634). Self-reported values were strongly correlated with measured values (Pearson's r: 0.92 and 0.89 for men and women, respectively, for height; 0.96 for both sexes for weight; 0.93 and 0.91 for men and women, respectively, for BMI). The differences in mean values were small. On average, height was overreported by 0.93 cm (SD = 2.48) for men and 1.23 cm (SD = 2.84) for women. Weight was underreported by 1.08 kg (SD = 2.55) for men and 0.88 kg (SD = 2.45) for women. BMI was underestimated by 0.68 kg/m(2) (SD = 1.16) for men and 0.79 kg/m(2) (SD = 1.49) for women. As age increases, height overreporting increased, particularly among women, but weight underreporting decreased for women. BMI underestimation increased for both sexes. Weighted kappa values showed a reasonably high concordance at 0.715 and 0.670 for men and women, respectively (P < 0.0001). Overweight (BMI 25.0 to 29.9) and obesity (BMI ≥ 30) prevalence rates were underestimated, with better specificity (range: 94.4-100%) than sensitivity (range: 59.3-65.1%). The accuracy of self-reported height and weight is reasonably high among elderly Japanese, suggesting that the information can be used in epidemiological surveys. However, caution should be exercised for the oldest age group (age 85+), as the accuracy declined. © 2011 Japan Geriatrics Society.

To investigate the relationship between sex hormones and metabolic syndrome (MS), as well as its components in elderly men. 1 505 elderly men (≥60 years old, mean age 75.4±9.7 years old) who participated in a routine health screening examination in PLA general hospital from May to June in 2012 were enrolled in this cross-sectional study. Serum lipids, glucose and sex hormones were measured along with body height, weight and blood pressure. Free testosterone (FT) and bioavailable testosterone (BT) were calculated. The correlation of serum sex hormones with the presence of MS and its components were analyzed. The prevalence of MS was 21.7% (326/1 505) in this study. Elderly men with MS had lower levels of sex hormone-binding globulin (SHBG), total testosterone (TT), FT and BT than those without MS. The levels of SHBG, TT, FT and BT were significantly lower in the overweight/obesity group, hyperglycemia group and dyslipidemia group than those in the respective control groups (P<0.05). Logistic regression analysis showed that the SHBG level was an independent risk factor for MS in elderly men(OR=0.977, 95%CI: 0.964-0.989, P<0.001), while the levels of TT, FT and BT were not associated with MS. The prevalence of MS gradually increased with decreasing of SHBG values (P<0.001). When comparing subjects in the lowest and highest quartile of SHBG, the former group demonstrated a 2.13-fold increase in the odds ratio for MS after adjusting for age, smoking, drinking and other sex hormone indices. In elderly men, lower SHBG level, not TT, FT or BT may be an independent predictor for the prevalence of MS, in which the mechanism requires further studies.

The experiences of elderly South Asian (SA) men who have immigrated to Canada provide unique insights to men's health and illness behaviors and beliefs. In this article, we describe the connections between masculinity, culture, and health among a cohort of 14 SA immigrant men. The findings indicated that participants' health behaviors were closely aligned to those of western men. However, a fine-grained analysis revealed how complex cultural connections informed and influenced many men's health behaviors and beliefs. Based on the study findings, recommendations for the future design of healthcare services targeted to SA men are made.

Prostate cancer of transition zone origin or anterior location has been recognized as infrequent, smaller in size and indolent, whereas, our previous report showed that transition zone/anterior cancer was frequently experienced in Japanese men. The current study was conducted to show clinicopathological characteristics of transition zone/anterior cancer. A total of 201 radical prostatectomy specimens were categorized as cancer of anterior or posterior prostate where more than two thirds of the tumor existed in the specific area. Clinicopathological characteristics including Gleason score, pathological stage, lymph node metastasis, extraprostatic extension, surgical incision into the prostate (shown as pT2+), and surgical margin status were compared between anterior and posterior cases. Cases were divided as 83, 73, and 45 of anterior, posterior cancer, and no dominance, respectively. Anterior cancers included significant numbers of high grade tumors (13/83 cases: 15.7%), which was less than posterior cancers (28.8%: 21/73). The cases in pT2+ were significantly more frequent in anterior cases than posterior ones (22.9% vs. 4.1%). No seminal vesicle invasion was shown in anterior cases. Thus, although anterior cancers are less aggressive than posterior cancers, a significant numbers of clinically important cancers were located in the anterior portion in Japanese men. © 2017 Japanese Society of Pathology and John Wiley & Sons Australia, Ltd.

Background Visceral obesity is positively related to insulin resistance. The nature of the relationship between waist circumference and insulin resistance has not been known in Japanese populations. This study examined the relationship between waist circumference and insulin resistance and evaluated the optimal cutoff point for waist circumference in relation to insulin resistance in middle-aged Japanese men. Methods Study subjects included 4800 Japanese men aged 39 to 60 years. Insulin resistance was evaluated by the homeostasis model assessment of insulin resistance (HOMA-IR). The relationship of waist circumference with HOMA-IR was assessed by use of adjusted means of HOMA-IR and odds ratios of elevated HOMA-IR defined as the highest quintile (≥2.00). Receiver operating characteristics (ROC) curve analysis using Youden index and the area under curve (AUC) was employed to determine optimal cutoffs of waist circumference in relation to HOMA-IR. Results Adjusted geometric means of HOMA-IR and prevalence odds of elevated HOMA-IR were progressively higher with increasing levels of waist circumference. In the ROC curve analysis, the highest value of Youden index was obtained for a cutoff point of 85 cm in waist circumference across different values of HOMA-IR. Multiple logistic regression analysis also indicated that the AUC was consistently the largest for a waist circumference of 85 cm. Conclusion Waist circumference is linearly related to insulin resistance, and 85 cm in waist circumference is an optimal cutoff in predicting insulin resistance in middle-aged Japanese men.

Type 2 diabetes increases the risk of disability. The purpose of this study was to clarify the explanatory factors for disability in Japanese diabetic elderly. The 6-year decline in physical disability and functional limitations was investigated among 317 elderly people with type 2 diabetes recruited in a large-scale prospective study of the Japanese Elderly Diabetes Intervention Trial. Information about diabetes, blood examinations and complications was obtained, and basic activities of daily living (ADL) and instrumental ADL (IADL) were assessed by total score of the Barthel index and the Tokyo Metropolitan Institute of Gerontology Index of Competence, respectively. After 6 years of follow up, 13.6% of patients had developed a new ADL disability and 38.3% had developed a new functional impairment. In the 65-74 years age group, basic ADL decreased only in males, whereas females became functionally impaired. In the 75-84 years age group, basic and IADL decreased in both males and females. Older age and metabolic syndrome were prognostic for impairment of basic ADL, whereas baseline IADL problems, lower cognitive function, physical inactivity and insulin therapy were significant predictors of a future decline in the IADL. This study identified several factors predicting the future decline of basic ADL and IADL in diabetic elderly patients, and provided a conceptual framework that might help to clarify the pathways leading to disability. Because the specific causes of each functional problem are modifiable, comprehensive treatment and care are needed to allow Japanese diabetic elderly patients to have more favorable living conditions. © 2012 Japan Geriatrics Society.

In this study we aimed to evaluate the frequency of cerumen impaction in Japanese elderly and clarify the associations between cerumen, cognitive function, and hearing impairment. The subjects enrolleded in this study were participants in the National Institute for Longevity Sciences, Longitudinal Study of Aging (NILS-LSA). The data of 792 community-dwelling participants aged 60 to 88 years old were collected. All had taken the Mini-Mental State Examination (MMSE) and had undergone pure tone audiometry (PTA) assessment and video recording of an otoscopic examination. We then analyzed associations between the incidence of the cerumen impaction of better-hearing ear, hearing level and MMSE scores using a general linear model. Cerumen impaction of the better-hearing ear was observed in 10.7% of all participants. In participants with an MMSE score of less than 24, the frequency of cerumen impaction was 23.3%. Cerumen was significant associated with poorer hearing after adjustment for sex and age (p=0.0001). Cerumen impaction also showed a significant association with a low MMSE score after adjustment for sex, age, hearing level and education (p=0.02). The frequency of cerumen impaction in Japanese elderly was estimated to be approximately 10%. The existence of cerumen impaction was associated with poorer hearing level and lower MMSE score.

Diet is considered an important factor for bone health, but is composed of a wide variety of foods containing complex combinations of nutrients. Therefore we investigated the relationship between dietary patterns and fall-related fractures in the elderly. We designed a population-based prospective survey of 1178 elderly people in Japan in 2002. Dietary intake was assessed with a 75-item food frequency questionnaire (FFQ), from which dietary patterns were created by factor analysis from 27 food groups. The frequency of fall-related fracture was investigated based on insurance claim records from 2002 until 2006. The relationship between the incidence of fall-related fracture and modifiable factors, including dietary patterns, were examined. The Cox proportional hazards regression model was used to examine the relationships between dietary patterns and incidence of fall-related fracture with adjustment for age, gender, Body Mass Index (BMI) and energy intake. Among 877 participants who agreed to a 4 year follow-up, 28 suffered from a fall-related fracture. Three dietary patterns were identified: mainly vegetable, mainly meat and mainly traditional Japanese. The moderately confirmed (see statistical methods) groups with a Meat pattern showed a reduced risk of fall-related fracture (Hazard ratio = 0.36, 95% CI = 0.13 - 0.94) after adjustment for age, gender, BMI and energy intake. The Vegetable pattern showed a significant risk increase (Hazard ratio = 2.67, 95% CI = 1.03 - 6.90) after adjustment for age, gender and BMI. The Traditional Japanese pattern had no relationship to the risk of fall-related fracture. The results of this study have the potential to reduce fall-related fracture risk in elderly Japanese. The results should be interpreted in light of the overall low meat intake of the Japanese population.

Coronary heart disease incidence and mortality remain very low in Japan despite major dietary changes and increases in risk factors that should have resulted in a substantial increase in coronary heart disease rates (Japanese paradox). Primary genetic effects are unlikely, given the substantial increase in coronary heart disease in Japanese migrating to the United States. For men aged 40-49 years, levels of total cholesterol and blood pressure have been similar in Japan and the United States throughout their lifetimes. The authors tested the hypothesis that levels of subclinical atherosclerosis, coronary artery calcification, and intima-media thickness of the carotid artery in men aged 40-49 years are similar in Japan and the United States. They conducted a population-based study of 493 randomly selected men: 250 in Kusatsu City, Shiga, Japan, and 243 White men in Allegheny County, Pennsylvania, in 2002-2005. Compared with the Whites, the Japanese had a less favorable profile regarding many risk factors. The prevalence ratio for the presence of a coronary calcium score of > or =10 for the Japanese compared with the Whites was 0.52 (95% confidence interval: 0.35, 0.76). Mean intima-media thickness was significantly lower in the Japanese (0.616 mm (standard error, 0.005) vs. 0.672 (standard error, 0.005) mm, p < 0.01). Both associations remained significant after adjusting for risk factors. The findings warrant further investigations.

The purpose of this study was to evaluate whether the Telephone Interview for Cognitive Status in Japanese (TICS-J) is accepted among community-dwelling elderly, to examine the correlations among gender, age or the duration of education and the TICS-J, as well as to grasp the subjects with probable cognitive impairment. A total of 12,059 community-dwelling elderly were invited to join the cognitive screening by the TICS-J, among which 3,482 responded, of these we were actually able to measure 2,620 and found out the educational back ground of the 2,431. They counted 1,186 men (age 72.3+/-5.7 (mean+/-SD) years old, duration of education 11.4+/-2.9 years) and 1,245 women (72.4+/-5.8, 10.3+/-2.2). The TICS-J was administered according to the TICS manual. The TICS-J consisted of orientation concerning name, time and place, counting backward from 20 to 1, remembering a word list, 7 serial subtractions, naming of verbal descriptions, repetition, recent memory, praxis and opposites. The subjects were divided into two groups by the duration of education (less than 11 years, or 11 years or more), or four groups by age (65-69, 70-74, 75-79 and 80 years old or more). There were no significant differences of total TICS-J scores between men and women, 34.3+/-3.5 and 34.4+/-3.6, respectively. The mean total score of the high education group (35.3+/-3.0) was significantly higher than that of the low education group (33.3+/-3.8). Moreover, the averages of the total scores decreased according to age increase. The number of the subjects who showed the total TICS-J scores below the cut-off point of 33 was 564 (23.2%). There was no difference between men and women with the average total score of the TICS-J, however, there were correlations between ages and extent of education and their average total scores. The TICS-J is useful to assess the cognitive function of the community-dwelling elderly.

The prognosis of super-elderly patients (age≥85 years) who undergo bradycardia pacemaker (PM) implantation remains unknown. We retrospectively enrolled 868 patients (men 49.0%, 76.6±10.6 years) who could walk unassisted and whose expected life expectancy was more than 1 year, receiving their first bradycardia PM implantation between January 1, 2006, and June 30, 2013. Clinical outcomes were compared between super-elderly patients (n=201, mean age 88.6±3.2 years) and younger patients (n=667, 73.0±9.3 years). At the end of a median 1285-day follow-up, 128 patients (14.7%) died, of which 54 were cardiac deaths (42.2%). Mortality rates were similar between the groups (16.4% vs. 14.2%, log-rank p=0.56) and across different indications for implantation (atrio-ventricular conduction disturbance or sick sinus syndrome, p=0.59), initial rhythms (sinus rhythm or persistent atrial fibrillation, p=0.62), pacing modes (dual chamber pacing or VVI pacing, p=0.26), and ventricular lead positions (septum or apex, p=0.52). On Cox proportional hazard model analysis, hypertension [hazard ratio (HR)=1.74, 95% confidence interval (CI)=1.19-2.54, p=0.004], diabetes mellitus (HR=2.18, 95% CI=1.51-3.14, p<0.001), history of myocardial infarction (HR=3.59, 95% CI=2.49-5.16, p<0.001), and history of stroke (HR=2.26, 95% CI=1.51-3.37, p<0.001) were independent predictors for mortality. The mortality rate of super-elderly patients who had no critical illnesses and were healthy enough to walk unassisted at the time of PM implantation was not inferior to that of younger patients. Prognosis was determined by comorbidities, but not by age, PM indication, initial rhythm, pacing leads, or mode. Copyright © 2016 Japanese College of Cardiology. Published by Elsevier Ltd.

Abstract The aim of this study was to investigate the osteoporosis prevalence and the risks of postmenopausal women and elderly men in Gansu province. This cross-sectional study involved 3359 postmenopausal women and 3205 elderly males who were randomly selected from 7 areas in Gansu province. Areal bone mineral density (BMD) (g/cm2) was measured at the distal one-third radius of the nonstressed forearm using dual-energy X-ray absorptiometry (DXA: Osteometer MediTech). Factors related to osteoporosis were analyzed. The prevalence of osteoporosis in the entire study population was 9.65% for postmenopausal women and 8.08% for elderly males by WHO criteria, while the rate of osteopenia were 27.09% for postmenopausal women and 26.68% for elderly males. Risk of osteoporosis was significantly associated with age, menopause age, duration of menopause, body mass index (BMI), educational level, and alcohol consumption in postmenopausal women. In elderly men, age, BMI, current smoking, alcohol consumption, physical activity, and sun exposure were associated with osteoporosis. The bone turnover markers osteocalcin (OC) and C-terminal cross-linked telopeptides of type I collagen (β-CTX) were inversely correlated with BMD in both genders; serum P and 25(OH)D found no significant correlation with BMD. Serum Ca showed a positive effect on BMD in elderly men only. The osteoporosis prevalence of postmenopausal women and the men aged over 60 years in Gansu province is presented. Risk of osteoporosis was significantly associated with age, menopause age, year since menopause, BMI, and educational level in postmenopausal women. In elderly men, age, BMI, and current smoking were associated with osteoporosis. This study also found that higher OC and β-CTX level were associated with lower BMD. Poor 25(OH)D, Ca, P status were not associated with an increased risk of low BMD. PMID:29068999

Andropausal and depressive symptoms are common in aging males and may be associated with hormone deficiency. We investigated the severity of andropausal and depressive symptoms, as well as their hormonal determinants, in 196 middle-aged and elderly men (age range: 40-80 years) with prediabetes (PD) and in 184 healthy peers. PD was diagnosed according to the definition of the American Diabetes Association. The severity of andropausal and depressive symptoms was assessed using the Aging Males' Symptoms Rating Scale and the Self-Rating Depression Scale. Total testosterone (TT), calculated free testosterone (cFT), dehydroepiandrosterone sulfate (DHEAS), and insulin-like growth factor 1 (IGF-1) were measured. The prevalence of andropausal syndrome in men with PD was significantly higher than that in healthy men (35% vs 11%, respectively). In men with PD aged 40-59 years, the severity of sexual, psychological, and all andropausal symptoms was greater than in healthy peers, while in elderly men (60-80 years), only the severity of psychological symptoms was greater than in healthy peers. The severity of depressive symptoms in the middle-aged men with PD was greater than in healthy peers, while the severity of depressive symptoms in elderly men with PD and healthy peers was similar. The higher prevalence of andropausal symptoms was independently associated with cFT and IGF-1 in middle-aged men and with TT and DHEAS in elderly men with PD. The more severe depression symptoms were associated with low TT and DHEAS in middle-aged men and with low cFT and DHEAS in elderly men with PD. In conclusion, the prevalence of andropausal symptoms, especially psychological, was higher in prediabetic patients as compared to healthy men, while the severity of depressive symptoms was higher only in middle-aged men with PD. Hormonal determinants of andropausal and depressive symptoms are different in middle-aged and elderly patients, but endocrine tests are necessary in all men with PD.

Activity patterns of elderly men and women.

The activity patterns of elderly men and women (greater than 60 years) were examined by diaries, ECG taperecorders, and electro-chemical integrators. Although the subjects thought that they were active relative to others of their age, both activity measurements and initial assessments of fitness indicated an inactive life style. At different periods of the day, the heart rate averaged 70-90 beats per minute, and the physical training threshold was rarely approached. During the week, the women engaged in 90 min. more physical activity than the men. However, at the weekend the men added an average of 100 min. of physical activity, whereas the women carried out 30 min. less physical work. Introduction of a 1-hour physical activity class four times per week increased the average daily energy expenditure by 150-200 kCal, to 2500 kCal in the men and 2200 kCal in the women. The added activity was sufficient to augment aerobic power, to induce favorable changes in body composition and to initiate change in other areas of life style, including a diminished use of the car.

Knowledge about factors influencing physical activity behavior is needed in order to tailor physical activity interventions to the individual. The aim of this study was to explore and describe the perceived reasons, barriers, and incentives to increased physical activity, as well as preferable activities, among elderly men in Sweden. In total, 150 men aged 50-86 years responded to a Web-based questionnaire. Men who reported that they exercised sometimes or often received questions about reasons for physical activity (n=104), while men who reported that they never or seldom exercised received questions about barriers (n=46). The most frequent perceived reason for being physically active was health (82%), followed by enjoyment (45%), and a desire to lose/maintain weight (27%). Lack of interest/motivation was identified as the primary perceived barrier (17%). Incentives for increasing the level of activity included becoming more motivated and having a training partner. Walking was the most preferred activity. Enjoyment and maintaining a good health were important reasons for engaging in physical activity among Swedish elderly men.

Identifying subjects at high risk of weight gain according to consumption of food groups is important for individualizing nutritional education, but prospective studies of this issue have been few. We determined whether intake of specific food groups could predict future weight gain. We evaluated data from health checkups on 1236 Japanese men aged 28 to 87 years in 2005 and 2006. Dietary intake was assessed by a 24-h dietary recall at baseline. Weight change was measured after 1 year. Weight increased in 44.7% (n = 553) of participants. Multivariate regression analysis involving many food groups showed a significant association between sugar intake and weight gain after adjustment for age, body mass index (BMI), total energy intake, alcohol, smoking and regular physical exercise (β = 0.22, P = 0.04). The effect of intake of 'fats and oils' was significant when adjusted for age and BMI, however, it became insignificant after adjustment for age, BMI and total energy intake. Intake of sugar, which was evaluated as a food group, was predictive of subsequent weight gain among Japanese men, even after adjustment for many confounders. This corroborates the evidence so far concerning the links between sugar intake and weight gain. Further long-term research is required to give robust recommendation to the public. © 2014 The Authors. Clinical Obesity © 2014 International Association for the Study of Obesity.

Apixaban, one of the non-vitamin K antagonist oral anticoagulants, was reported to be effective and safe in stroke prevention in patients with atrial fibrillation (AF) based on the global randomized clinical trial, but data are limited on the efficacy and safety of apixaban in Japanese elderly patients. The J-ELD AF Registry is a large-scale, contemporary observational study, continuously and prospectively registering elderly Japanese patients with AF aged 75 years or older who are currently taking apixaban or the elderly who are to receive apixaban in daily clinical practice, and accumulating the outcomes during one-year follow-up period. In addition to standard baseline characteristics, prothrombin time and anti-Xa activity will be measured to investigate the biomarker characteristics. The primary efficacy endpoints will be stroke and systemic embolism, and the primary safety endpoint will be major bleeding requiring hospitalization. The secondary endpoints in this study will be all-cause death, cardiovascular death, acute myocardial infarction, and the composite of stroke/systemic embolism, cardiovascular death, and acute myocardial infarction. As a primary analysis, the primary/secondary endpoints in the enrolled patients will be totalized for the entire group, and the incidence of events will be described by age, CHADS 2 score, HAS-BLED score, and apixaban dose (5 or 2.5mg bid). The factors that independently predict the incidence of the primary/secondary endpoints will be searched for by Cox regression. The relationship between the biomarkers and the primary/secondary endpoints will also be examined in an explorative manner. This study will provide important information on the efficacy and safety of apixaban in elderly Japanese patients aged 75 years or older, and those of low-dose administration of apixaban (2.5mg bid) for which many of the Japanese elderly are indicated.

Data were derived from the National Institute for Longevity Sciences-Longitudinal Study of Aging. Subjects comprised 403 men and 373 women aged 60-81 years at baseline who participated in the follow-up study at least once. Bean, soy product and soy isoflavone intake was assessed using a 3-day dietary record at baseline. Cognitive function was assessed by the Mini-Mental State Examination (MMSE). MMSE scores of ≤23 were used to define cognitive impairment. The relationship between bean, soy product and soy isoflavone intake and cognitive impairment was assessed using a generalized estimating equation. Multivariate-adjusted odds ratios (95% confidence intervals) for cognitive impairment with a 1 s.d. increase in total bean, total soybean and total soy isoflavone intakes were 0.48 (0.28-0.81; p = 0.006), 0.51 (0.32-0.83; p = 0.007), and 0.55 (0.32-0.93; p = 0.026), respectively, in women. Total soybean and soy isoflavone intake might decrease the risk of cognitive impairment in elderly Japanese women.

Despite the fact that simultaneous performance of resistance and aerobic exercises (i.e., concurrent exercise) has become a standard exercise prescription for the elderly, no information is available on its effects on post-exercise hypotension (PEH) in elderly men with hypertension. To compare the effects of different types of exercise on PEH in elderly men with hypertension. Twenty elderly men with essential hypertension participated in three crossover interventions, in random order, and on separate days: a non-exercise control session at seated rest, aerobic exercise performed for 45min, and 45min of concurrent resistance and aerobic exercise consisted of 4 sets of 8 repetitions at 70% 1RM of resistance exercise followed by aerobic exercise on treadmill. After each session, blood pressure (BP) was measured continuously for 1h in the laboratory and for 24h under ambulatory conditions. During the first hour in laboratory, diastolic BP was lower after aerobic (-5mmHg) and concurrent exercise (-6mmHg) in comparison with Control. Day-time diastolic BP was significantly lower after aerobic exercise (-7mmHg) when compared to the control. No significant differences were found among the three experimental sessions for night-time and 24-hour diastolic BP, as well as day-time, night-time and 24-hour systolic BP. Concurrent exercise produced acute PEH similar to aerobic exercise but such effect did not last as long as aerobic exercise in elderly patients with essential hypertension.

Spoken bilingualism may be associated with cognitive reserve. Mastering a complicated written language may be associated with additional reserve. We sought to determine if midlife use of spoken and written Japanese was associated with lower rates of late life cognitive decline. Participants were second-generation Japanese-American men from the Hawaiian island of Oahu, born 1900-1919, free of dementia in 1991, and categorized based on midlife self-reported use of spoken and written Japanese (total n included in primary analysis = 2,520). Cognitive functioning was measured with the Cognitive Abilities Screening Instrument scored using item response theory. We used mixed effects models, controlling for age, income, education, smoking status, apolipoprotein E e4 alleles, and number of study visits. Rates of cognitive decline were not related to use of spoken or written Japanese. This finding was consistent across numerous sensitivity analyses. We did not find evidence to support the hypothesis that multilingualism is associated with cognitive reserve.

This study aimed to determine the association between sarcopenia, defined by muscle mass, muscle strength, and physical performance, and higher-level functional capacity in community-dwelling Japanese elderly people. Subjects were 1158 elderly, community-dwelling Japanese people aged 65 or older. We used bioelectrical impedance analysis to measure muscle mass, grip strength to measure muscle strength, and usual walking speed to measure physical performance. Sarcopenia was characterized by low muscle mass, plus low muscle strength or low physical performance. Subjects without low muscle mass, low muscle strength, and low physical performance were classified as "normal." Examination of higher-level functional capacity was performed using the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC). The TMIG-IC is a 13-item questionnaire completed by the subject; it contains five questions on self-maintenance and four questions each on intellectual activity and social role. Sarcopenia was identified in 11.3% and 10.7% of men and women, respectively. The percentage of disability for instrumental activities of daily living (IADL) was 39.0% in men with sarcopenia and 30.6% in women with sarcopenia. After adjustment for age, in men, sarcopenia was significantly associated with IADL disability compared with intermediate and normal subjects. In women, sarcopenia was significantly associated with every subscale of the TMIG-IC disability compared with intermediate and normal subjects. This study revealed that sarcopenia, defined by muscle mass, muscle strength, and physical performance, had a significant association with disability in higher-level functional capacity in elderly Japanese subjects. Interventions to prevent sarcopenia may prevent higher-level functional disability among elderly people. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

To examine the relationship between depression and various components of body composition, including fat and muscle, in elderly Koreans. A cross-sectional sample of a longitudinal cohort from the Ansan Geriatric (AGE) Study. Elderly people living in urban area (Ansan City, South Korea). Eight hundred thirty-six participants (378 male, 458 female) aged 60 and older were recruited from April 2006 to January 2008. Depressive symptoms were examined using the Korean version of the 30-item Geriatric Depression Scale (KGDS). Participants taking antidepressant medications or with a KGDS score of 14 or greater were classified as having depression. Abdominal visceral fat area (VFA) and subcutaneous fat area were assessed using single-slice computed tomography, and appendicular skeletal muscle mass (ASM) and percentage body fat (%BF) were determined using whole-body dual-energy X-ray absorptiometry. Elderly men with depression had a lower ASM than those without depression (P = .01) after adjusting for age, body weight, and height. In men, the risk of depression was lower with higher body mass index (BMI) (odds ratio (OR) per 1-standard deviation (SD) increase = 0.70, 95% confidence interval (CI) = 0.51-0.96) after adjusting for all confounding variables and higher ASM (OR per 1-SD increase = 0.49; 95% CI = 0.29-0.85) after controlling for age, height, and weight. Similarly, depression was negatively associated with BMI in women (OR per 1-SD increase = 0.73; 95% CI = 0.56-0.95). Waist circumference, %BF, and VFA were not consistently associated with depression in men or women. Depression in elderly Koreans is associated with low body mass and sarcopenia, especially in men. © 2011, Copyright the Authors Journal compilation © 2011, The American Geriatrics Society.

This study aimed to develop and cross-validate prediction equations for estimating appendicular skeletal muscle mass (ASM) and to examine the relationship between sarcopenia defined by the prediction equations and risk factors for cardiovascular diseases (CVD) or osteoporosis in Japanese men and women. Subjects were healthy men and women aged 20-90 years, who were randomly allocated to the following two groups: the development group (D group; 257 men, 913 women) and the cross-validation group (V group; 119 men, 112 women). To develop prediction equations, stepwise multiple regression analyses were performed on data obtained from the D group, using ASM measured by dual-energy X-ray absorptiometry (DXA) as a dependent variable and five easily obtainable measures (age, height, weight, waist circumference, and handgrip strength) as independent variables. When the prediction equations for ASM estimation were applied to the V group, a significant correlation was found between DXA-measured ASM and predicted ASM in both men and women (R 2  = 0.81 and R 2  = 0.72). Our prediction equations had higher R 2 values compared to previously developed equations (R 2  = 0.75-0.59 and R 2  = 0.69-0.40) in both men and women. Moreover, sarcopenia defined by predicted ASM was related to risk factors for osteoporosis and CVD, as well as sarcopenia defined by DXA-measured ASM. In this study, novel prediction equations were developed and cross-validated in Japanese men and women. Our analyses validated the clinical significance of these prediction equations and showed that previously reported equations were not applicable in a Japanese population.

To determine whether presence of ikigai as a positive psychological factor is associated with decreased risks for all-cause and cause-specific mortality among middle-aged and elderly Japanese men and women. From 1988 to 1990, a total of 30,155 men and 43,117 women aged 40 to 79 years completed a lifestyle questionnaire including a question about ikigai. Mortality follow-up was available for a mean of 12.5 years and was classified as having occurred in the first 5 years or the subsequent follow-up period. Associations between ikigai and all-cause and cause-specific mortality were assessed using a Cox's regression model. Multivariate hazard ratios (HRs) were adjusted for age, body mass index, drinking and smoking status, physical activity, sleep duration, education, occupation, marital status, perceived mental stress, and medical history. During the follow-up period, 10,021 deaths were recorded. Men and women with ikigai had decreased risks of mortality from all causes in the long-term follow-up period; multivariate HRs (95% confidence intervals, CIs) were 0.85 (0.80-0.90) for men and 0.93 (0.86-1.00) for women. The risk of cardiovascular mortality was reduced in men with ikigai; the multivariate HR (95% CI) was 0.86 (0.76-0.97). Furthermore, men and women with ikigai had a decreased risk for mortality from external causes; multivariate HRs (95% CIs) were 0.74 (0.59-0.93) for men and 0.67 (0.51-0.88) for women. The findings suggest that a positive psychological factor such as ikigai is associated with longevity among Japanese people.

Erythroid abnormalities including anemia and polycythemia are often observed in the general clinical setting. Because recent studies reported that adiponectin negatively affects hematopoiesis, we performed a prospective observational study to assess the relationship between anemia and adiponectin, as well as other parameters, in 1029 Japanese subjects (477 men and 552 women) 40 years of age and older. Body measurements, blood tests, and nutrition intake studies were performed at baseline, and 5 to 7 years later (follow-up). Hemoglobin (Hb) and hematocrit (Hct) levels in men with high serum adiponectin levels were lower at follow-up than at baseline. Multiple regression analysis showed that age, body mass index, adiponectin, and glutamic-pyruvic transaminase were significantly associated with erythroid-related variables (red blood cells, Hb, and Hct) in both men and women (P <0.05). In a logistic regression analysis, adiponectin, fasting blood glucose, and β-natriuretic peptide were significant risk factors for anemia in men, and blood urea nitrogen and amylase were significant risk factors in women. Physical features and nutrient intake were not risk factors for anemia. Our study demonstrates, both clinically and epidemiologically, that a high serum adiponectin level decreases the amounts of erythroid-related variables and is a risk factor for anemia in Japanese men.

The Japanese Food Guide Spinning Top was developed by the Japanese Ministry of Health, Labor, and Welfare and the Ministry of Agriculture, Forestry, and Fishery to promote healthful diets. Adherence to the Japanese Food Guide Spinning Top was evaluated in terms of future mortality in a prospective cohort study. A prospective cohort study among men and women in a general Japanese population. The cohort consisted of 13,355 men and 15,724 women residing in Takayama, Japan, in 1992. At baseline, a food frequency questionnaire was administered, and adherence to the food guide was measured based on consuming the recommended number of servings of grains, vegetables, fish and meat, milk, and fruits, as well as total daily energy intake and energy from snacks and alcoholic beverages. Higher scores indicated better adherence to the recommendations on a scale of 0 to 70. Based on data obtained from the Office of the National Vital Statistics, deaths occurring among members of the cohort were prospectively noted from 1992 to 1999. To assess the magnitude of association of adherence scores with subsequent mortality, a Cox proportional hazard model was applied to estimate hazard ratios (HRs) with 95% confidence intervals (CIs). Among women, the adherence score was significantly associated with a lower risk of mortality from all causes (comparing highest and lowest quartiles of the score, HR 0.78, 95% CI 0.65 to 0.94, P for trend 0.01) in a multivariate analysis; noncardiovascular, noncancer causes (HR 0.69, 95% CI 0.50 to 0.96, P for trend 0.04) and cardiovascular disease (HR 0.76, 95% CI 0.56 to 1.04, P for trend0.05). No statistically significant association was observed between the adherence score and mortality among men. The results suggest that diets based on the food guide have the benefit of reducing future mortality in women.

Little is known regarding occupation and industry differences in relation to suicide risk. This study examined differences in suicide risk among Japanese men of working age (25-59 years) during 2010. We analysed the Japanese government's 2010 national survey data regarding occupation and industry-specific death rates. Poisson regression models were formulated for each occupation and industry to estimate the relative risk of death by suicide. Potential interactions between age and occupation/industry were also examined. Suicide incidence was highest among workers in the fields of agriculture and mining. When compared with referent groups (sales for occupation and wholesale and retail for industry), the age-adjusted relative risk of suicide was highest for administrative and managerial workers (Incident Relative Risk [IRR]: 3.91, 95% Confidence Interval [95%CI]: 3.16-4.85), service industries (IRR: 3.63, 95%CI: 2.93-4.51) and agriculture (IRR: 3.53, 95%CI: 2.84-4.38) occupations, and for mining (IRR: 23.9, 95%CI: 19.4-29.4), fisheries (IRR: 6.26, 95%CI: 5.03-7.80), electricity and gas (IRR: 5.86, 95%CI: 4.71-7.30) and agricultural industries (IRR: 4.73, 95%CI: 3.78-5.91). Bias resulting from misclassification of deceased individuals' occupation or industry was a potential limitation of this study. Furthermore, detailed information regarding occupation-related factors, such as employment status, had not been recorded in the initial survey. These findings help elucidate Japanese occupations and industries with a higher suicide risk, most likely due to economic changes or workplace factors relating to stress and depression.

Adiponectin is an adipocyte-specific protein that plays a role in obesity, insulin resistant, lipid metabolism, and anti-inflammation. Hypoadiponectinemia may be associated with a higher risk for type 2 diabetes and cardiovascular disease. Some studies suggest that adiponectin levels are modulated by lifestyle factors, but little is known about the associations between lifestyle factors and plasma adiponectin levels in Japanese people. We therefore investigated the associations between lifestyle factors and plasma adiponectin levels in general Japanese men. The subjects were 202 Japanese male workers who participated in an annual health check. They provided details about anthropometrical data, blood collection, their use of prescribed medication, and the clinical history of their families. They also completed a self-administered questionnaire about their lifestyles. Subjects with plasma adiponectin levels below 4.0 microg/ml had significantly lower levels of HDL cholesterol and higher levels of BMI, SBP, DBP, total cholesterol, FBG, and platelets than did subjects with higher adiponectin levels. In multiple logistic regression after multiple adjustment, a plasma adiponectin level below 4.0 microg/ml was significantly associated with smoking (odds ratio [OR] = 2.08, 95% confidence interval [CI] = 1.01-4.30), a daily diet rich in deep-yellow vegetables (OR = 0.25, 95% CI= 0.07-0.91), frequent eating out (OR = 2.45, 95% CI = 1.19-5.08), and physical exercise two or more times a week (OR = 0.21, 95% CI = 0.06-0.74). Our findings show that adiponectin levels in general Japanese men are independently related to smoking, dietary factors, and physical exercise. We think that lifestyle habits might independently modulate adiponectin levels and that adiponectin might be the useful biomarker helping people to avoid developing type 2 diabetes and cardiovascular disease by modifying their lifestyles.

Pain assessment in non-communicative patients relies primarily on observation scales. The DOLOPLUS-2 is a behavioral pain assessment scale for the elderly with impaired verbal communication. It rates five somatic items, two psychomotor items, and three psychosocial items as indicators of pain. The aims of the present study were to develop a Japanese version of the DOLOPLUS-2 and to apply it to elderly patients with Alzheimer's disease (AD). The translated instrument was evaluated with reference to Japanese patients with AD experiencing pain during post-surgery rehabilitation for hip fractures and who were unable to use any self-reported pain measures. After translation and back-translation, 21 registered nurses tested 'Version 1' of the pain assessment scale on three patients. The ratings of the nurses and researcher were compared and the number of matching scores determined. Semistructured interviews were conducted with the nurses and patient case studies were recorded. The results of the interviews provided the basis for the development of 'Version 2' of the scale, which was then tested with six patients and 31 nurses using the same procedures as for the testing of Version 1. The intraclass correlation coefficient for inter-rater reliability for the Version 2 administrators was 0.90 (P < 0.001), with a 95% confidence interval of 0.88-0.92; the degree of agreement by items (0.67-0.90) was excellent. Nurses' comments for Version 1 revealed that it was 'difficult to use' and that 'some Japanese expressions and explanations needed improvement'. In contrast, the nurses' comments on Version 2 indicated that there were no problems. Analysis of patient case studies in Version 2 indicated that pain scores were high only when the patients clearly would have had pain, such as when they started with full weight bearing. On the basis of these results, we developed a final version of the Japanese DOLOPLUS-2. The findings of the present study suggest that Version 2 of the

Background There has been considerable interest in Japanese society in the problem of work-related stress leading to depressive symptoms, and an increasing number of primary houseworkers maintain paid employment. The purpose of this study was to examine the differential impact of multiple roles associated with psychological distress among Japanese workers. Methods We studied 722 men and women aged 18–83 years in a cross-sectional study. The K10 questionnaire was used to examine psychological distress. Results The proportion of participants with psychological distress was higher in women (17.8%) compared with men (11.5%). Having three roles significantly decreased the risk of psychological distress [women: odds ratio (OR), 0.37-fold; men: OR, 0.41] compared with only one role. In working married women, there was significantly less psychological distress (OR, 0.27), and those with childrearing or caregiving responsibilities for elderly parents had significantly less psychological distress (OR, 0.38) than those with only an employment role. Similarly, working married men who had childrearing or caregiving responsibilities for elderly parents had significantly less psychological distress (OR, 0.41) than those who had only an employment role. Conclusion The present study demonstrated that participants who had only an employment role had an increased risk of psychological distress. The degree of psychological distress was not determined solely by the number of roles. It is important to have balance between work and family life to reduce role conflict and/or role submersion, which in turn may reduce the risk of psychological distress. PMID:26106510

We investigated whether the single nucleotide polymorphism rs174547 (T/C) of the fatty acid desaturase-1 gene, FADS1, is associated with changes in erythrocyte membrane and plasma phospholipid (PL) long-chain polyunsaturated fatty acid (LCPUFA) composition in elderly Japanese participants (n=124; 65 years or older; self-feeding and oral intake). The rs174547 C-allele carriers had significantly lower arachidonic acid (ARA; n-6 PUFA) and higher linoleic acid (LA, n-6 PUFA precursor) levels in erythrocyte membrane and plasma PL (15% and 6% ARA reduction, respectively, per C-allele), suggesting a low LA to ARA conversion rate in erythrocyte membrane and plasma PL of C-allele carriers. α-linolenic acid (n-3 PUFA precursor) levels were higher in the plasma PL of C-allele carriers, whereas levels of the n-3 LCPUFAs eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA) were unchanged in erythrocyte membrane and plasma PL. Thus, rs174547 genotypes were significantly associated with different ARA compositions of the blood of elderly Japanese. Copyright © 2015 Elsevier Ltd. All rights reserved.

To evaluate long-term, multiple risk factor intervention on physical, psychological and mental prognosis, and development of complications and cardiovascular disease in elderly type 2 diabetes patients. Our randomized, controlled, multicenter, prospective intervention trial included 1173 elderly type 2 diabetes patients who were enrolled from 39 Japanese institutions and randomized to an intensive or conservative treatment group. Glycemic control, dyslipidemia, hypertension, obesity, diabetic complications and atherosclerotic disease were measured annually. Instrumental activity of daily living, cognitive impairment, depressive symptoms and diabetes burden were assessed at baseline and 3 years. There was no significant difference in clinical or cognitive parameters at baseline between the two groups. The prevalence of low activities of daily living, depressive symptoms and cognitive impairment was 13%, 28% and 4%, respectively, and was similar in the two groups. A small, but significant difference in HbA1c between the two groups was observed at 1 year after the start of intervention (7.9% vs 8.1%, P < 0.05), although this significant difference was not observed after the second year. With the exception of coronary revascularization, there was no significant difference in fatal or non-fatal events between the two groups. Composite events were also similar in the two groups. This study showed no significant differences in fatal or non-fatal events between intensive and conventional treatment. The present study might clarify whether treatment of risk factors influences function and quality of life in elderly diabetic patients. © 2012 Japan Geriatrics Society.

Occupation- and industry-based risks for stroke and ischemic heart disease may vary among Japanese working-aged men. We examined the differences in mortality rates between stroke and ischemic heart disease by occupation and industry among employed Japanese men aged 25-59 years. In 2010, we obtained occupation- and industry-specific vital statistics data from the Japanese Ministry of Health, Labour, and Welfare dataset. We analyzed data for Japanese men who were aged 25-59 years in 2010, grouped in 5-year age intervals. We estimated the mortality rates of stroke and ischemic heart disease in each age group for occupation and industry categories as defined in the national census. We did not have detailed individual-level variables. We used the number of employees in 2010 as the denominator and the number of events as the numerator, assuming a Poisson distribution. We conducted separate regression models to estimate the incident relative risk for stroke and ischemic heart disease for each category compared with the reference categories "sales" (occupation) and "wholesale and retail" (industry). When compared with the reference groups, we found that occupations and industries with a relatively higher risk of stroke and ischemic heart disease were: service, administrative and managerial, agriculture and fisheries, construction and mining, electricity and gas, transport, and professional and engineering. This suggests there are occupation- and industry-based mortality risk differences of stroke and ischemic heart disease for Japanese working-aged men. These differences in risk might be explained to factors associated with specific occupations or industries, such as lifestyles or work styles, which should be explored in further research. The mortality risk differences of stroke and ischemic heart disease shown in the present study may reflect an excessive risk of Karoshi (death from overwork).

Sex- and age-related differences in mid-thigh composition and muscle quality remain unclear. The present study aimed to clarify these differences using computed tomography in middle-aged and elderly Japanese. A total of 2310 participants (age 40-89 years), who were randomly selected from the local residents, underwent computed tomography examination of the right mid-thigh. Thigh circumference and cross-sectional areas of the thigh, muscle, quadriceps, non-quadriceps, fat, and bone were measured. Knee extension strength and muscle quality index (knee extension strength/quadriceps cross-sectional area) were also assessed. Sex- and age-related differences in these indices were analyzed. The thigh cross-sectional area in men and women decreased by 0.6% and 0.5%/year, respectively, because of a decrease in muscle cross-sectional area (men 75.2%, women 40.6%), fat cross-sectional area (men 24.4%, women 59.6%) and bone cross-sectional area (men 0.5%, women -0.2%). Muscle cross-sectional area in men and women decreased by 0.6% and 0.4%/year, respectively, because of a decrease in quadriceps cross-sectional area (men 65.6%, women 81.6%) and non-quadriceps cross-sectional area (men 34.4%, women 18.4%). Muscle quality in men and women decreased by 0.4% and 0.3%/year, respectively. Thigh cross-sectional area decreased with age mainly because of a decrease in muscle cross-sectional area in men and fat cross-sectional area in women. The rate of decrease in muscle cross-sectional area was 1.5-fold higher in men than in women. Muscle cross-sectional area decreased with age mainly because of a decrease in quadriceps cross-sectional area, especially in women. Decrease in muscle quality with age was similar in both sexes. © 2014 Japan Geriatrics Society.

We previously showed the prevalence of dementia in the town of Tajiri (Miyagi Prefecture, Japan), and found it to be 8.0%. The first population-based study on dementia in Brazil (Catanduva) disclosed the prevalence as being 7.1%. To evaluate the effects of environment on development of dementia, elderly Japanese immigrants living in Brazil were examined. Brazil is the country with the largest number of Japanese immigrants. All immigrants aged 65 years and over from Miyagi Prefecture, living in the four cities of the São Paulo Metropolitan area were targeted (n = 192). We were able to examine 166 subjects (86.5%). The diagnosis of dementia was based on the DSM-IV with the severity assessed by the CDR (clinical dementia rating) scales. The cognitive ability screening instrument (CASI) was used for neuropsychological assessment. Thirteen subjects were diagnosed with dementia, CDR 1-3, the prevalence being 7.8%. Older subjects suffered more from dementia, and, paradoxically, the more highly educated subjects also suffered more. All the CASI items, except for long-term memory and visual construction, significantly deteriorated in the CDR 0.5 group compared with the CDR 0 group. The prevalence of dementia was not thought to be affected by environmental factors. A paradoxically higher rate of dementia in the more educated subjects was probably due to the historical problems of the immigrants. Intact CASI item long-term memory in the CDR 0.5 group indicated that suspected dementia patients could maintain this function. This is the first epidemiological study on dementia in elderly Japanese immigrants in Brazil. Copyright 2001 John Wiley & Sons, Ltd.

This study assessed the association between sarcopenia (using the definition of the European Working Group on Sarcopenia in Older People) and fall in the past year among community-dwelling Japanese elderly. Subjects were 1110 community-dwelling Japanese aged 65 or older. We used bioelectrical impedance analysis (BIA) to measure muscle mass, grip strength to measure muscle strength, and usual walking speed to measure physical performance in a baseline study. "Sarcopenia" was characterized by low muscle mass and low muscle strength or low physical performance. "Presarcopenia" was characterized only by low muscle mass. Subjects who did not have any of these deficiencies were classified as "normal." We then administered a questionnaire assessing age, sex, household status, chronic illness, lifestyle-related habits, and fall. This study showed the prevalence of fall was 16.9% and 21.3% in men and women, respectively, while that of sarcopenia was 13.4% and 14.9% in men and women, respectively. In men and women, the prevalence of sarcopenia was higher among those who had fallen. A logistic regression analysis using age, body fat, current drinker status, and physical inactivity for men, and age, body fat, smoking, and diabetes for women as covariate variables revealed that sarcopenia was significantly associated with a history of fall. The odds ratio for fall in the sarcopenia group relative to the normal group was 4.42 (95%CI 2.08-9.39) in men and 2.34 (95%CI 1.39-3.94) in women. This study revealed sarcopenia to be associated with falling in elderly Japanese. Sarcopenia prevention interventions may help prevent falls among elderly individuals.

To investigate the real-world safety of ipragliflozin in elderly Japanese patients with type 2 diabetes mellitus (T2DM). Japanese patients (≥65 years old) who were first prescribed ipragliflozin within 3 months after its launch in April 2014 were registered in this post-marketing surveillance (PMS). Final data collection was in July 2015. Survey items included demographics, treatments, adverse drug reactions (ADRs), vital signs, and laboratory variables. The PMS included 8505 patients (4181 males/4324 females). The mean age and diabetes duration were 72.3 years and 10.6 years, respectively. In 84.3% of patients, ipragliflozin was prescribed at 50 mg/day, which was continued unchanged. Overall, 16.91% of patients experienced 1880 ADRs, and 165 ADRs were classified as serious in 127 patients (1.49%). ADRs of special interest included skin complications, volume depletion, polyuria/pollakiuria, genital infection, urinary tract infection, renal disorders, hypoglycemia, cerebrovascular disease, cardiovascular disease, malignant tumor, fracture, and ketone body-related events. This 1-year PMS revealed probable ADRs in elderly Japanese patients with T2DM prescribed ipragliflozin in real-world settings, with no new safety concerns. The risk factors for ADRs varied but could be rationalized. The results should help physicians to identify possible treatment-emergent ADRs in ipragliflozin-treated patients.

Genetic polymorphisms and sex differences are suggested to affect muscle fiber composition; however, no study has investigated the effects of genetic polymorphisms on muscle fiber composition with respect to sex differences. Therefore, the present study examined the effects of genetic polymorphisms on muscle fiber composition with respect to sex differences in the Japanese population. The present study included 211 healthy Japanese individuals (102 men and 109 women). Muscle biopsies were obtained from the vastus lateralis to determine the proportion of myosin heavy chain (MHC) isoforms (MHC-I, MHC-IIa, and MHC-IIx). Moreover, we analyzed polymorphisms in α-actinin-3 gene ( ACTN3; rs1815739 ), angiotensin-converting enzyme gene ( ACE; rs4341 ), hypoxia-inducible factor 1 α gene ( rs11549465 ), vascular endothelial growth factor receptor 2 gene ( rs1870377 ), and angiotensin II receptor, type 2 gene ( rs11091046 ), by TaqMan single-nucleotide polymorphism genotyping assays. The proportion of MHC-I was 9.8% lower in men than in women, whereas the proportion of MHC-IIa and MHC-IIx was higher in men than in women (5.0 and 4.6%, respectively). Men with the ACTN3 RR + RX genotype had a 4.8% higher proportion of MHC-IIx than those with the ACTN3 XX genotype. Moreover, men with the ACE ID + DD genotype had a 4.7% higher proportion of MHC-I than those with the ACE II genotype. Furthermore, a combined genotype of ACTN3 R577X and ACE insertion/deletion (I/D) was significantly correlated with the proportion of MHC-I ( r = -0.23) and MHC-IIx ( r = 0.27) in men. In contrast, no significant correlation was observed between the examined polymorphisms and muscle fiber composition in women. These results suggest that the ACTN3 R577X and ACE I/D polymorphisms independently affect the proportion of human skeletal muscle fibers MHC-I and MHC-IIx in men but not in women. NEW & NOTEWORTHY In men, the RR + RX genotype of the α-actinin-3 gene ( ACTN3) R577X polymorphism was

Purpose To identify factors related to total mortality in older Japanese men in Japan and Hawaii. Methods Baseline data were collected from 1980 to 1982 in 1,379 men in Hawaii and 954 men in Japan. Ages ranged from 61 to 81 years with mortality follow-up over a 19 year period. Results Compared to Japan, men in Hawaii had a 2-fold excess of diabetes and a 4-fold excess of prevalent coronary heart disease (p<0.001). Total cholesterol and body mass index were also higher in Hawaii (p<0.001). In contrast, men in Japan had higher systolic blood pressure and were nearly 3-times more likely to smoke cigarettes (p<0.001). Although each cohort had elements of a poor risk factor profile, there was a 1.4-fold excess in the risk of death in Japan (49.4 vs. 36.2/1,000 person-years, p<0.001). While mortality was similar after risk factor adjustment, only blood pressure and cigarette smoking accounted for the higher risk of death in Japan. Conclusions Cigarette smoking and hypertension explain much of the excess mortality in Japan versus Hawaii. In this comparison of genetically similar cohorts, evidence further suggests that Japanese in Japan are equally susceptible to develop the same adverse risk factor conditions that exist in Hawaii.

To evaluate the utility of the Mini-Nutritional Assessment (MNA) in assessing nutritional, physical and psychosocial functions in community-living elderly individuals. A cross-sectional study of elderly individuals investigated in August 2007 and August-September 2008. Nutritional status was assessed using serum biomarkers, anthropometric measurements and the MNA. Physical function was assessed by measuring grip strength and both usual and maximum walking speeds. The Geriatric Depression Scale (GDS) was used to measure the individual's depressive state. Elder-care facilities in Tokyo, Japan. Community-living elderly individuals aged ≥65 years (n 130). The MNA evaluation classified twenty-seven (20·8 %) individuals as being at risk for malnutrition (MNA score ≤23·5); these at-risk individuals included a high proportion of the elderly aged ≥75 years. MNA scores correlated with nutritional biomarkers (total protein, albumin, cholinesterase, Hb) and anthropometric measurements (triceps skinfold, subscapular skinfold, mid-arm muscle area) and exhibited a strong correlation with grip strength and GDS score. Multivariate analysis revealed that grip strength, GDS score, marital status and maximum walking speed are strong predictors of MNA score. The MNA is considerably useful in providing a comprehensive assessment of nutritional status in elderly, community-living Japanese. However, larger-scale epidemiological studies are needed to determine the utility and the appropriate cut-off point of the MNA as a screen for risk of malnutrition.

It is unclear whether light physical activity is beneficially associated with insulin resistance, similar to moderate and/or vigorous physical activity. This cross-sectional study was performed to determine the relationship between the amount of light physical activity, as determined with a triaxial accelerometer, and insulin resistance. A total of 807 healthy men and women participated in this study. Physical activity was measured using a triaxial accelerometer worn for 28 days and summarized as light intensity (1.1-2.9 METs) or moderate to vigorous intensity (≥ 3.0 METs). Insulin resistance was evaluated by HOMA_R (FPG [mg/dL] × IRI [μU/mL]/405). The daily time spent in light physical activity was inversely associated with HOMA_R (r = -0.173, P < 0.05). After adjustment for confounders, the association between light physical activity and HOMA_R remained statistically significant (β = -0.119, P < .05). Light physical activity remained significantly associated with HOMA_R following further adjustment for moderate to vigorous intensity activity (β = -0.125, P < .05). Similar results were observed when light physical activity was modeled as quartiles, especially in elderly women. These cross-sectional data suggest that light-intensity physical activity is beneficially associated with insulin resistance in elderly Japanese women.

Physiological changes in thyroid hormone concentrations might be related to changes in the overall physical function in the elderly. We determined to what extent thyroid hormone concentrations are related to physical function and mortality in elderly men. A longitudinal population study (the Zoetermeer study) was conducted. Mortality was registered in the subsequent 4 yr. Four hundred three independently and ambulatory living men (aged 73-94 yr) participated. The study examined the association between serum thyroid hormones and parameters of physical function as well as the association with mortality. TSH, free T4 (FT4) total T4, T3, rT3, and T4-binding globulin were measured. Physical function was estimated by the number of problems in activities of daily living, a measure of physical performance score (PPS), leg extensor strength and grip strength, bone density, and body composition. Serum rT3 increased significantly with age and the presence of disease. Sixty-three men met the biochemical criteria for the low T3 syndrome (decreased serum T3 and increased serum rT3). This was associated with a lower PPS, independent of disease. Furthermore, higher serum FT4 (within the normal range of healthy adults) and rT3 (above the normal range of healthy adults) were related with a lower grip strength and PPS, independent of age and disease. Isolated low T3 was associated with a better PPS and a higher lean body mass. Low FT4 was related to a decreased risk of 4-yr mortality. In a population of independently living elderly men, higher FT4 and rT3 concentrations are associated with a lower physical function. High serum rT3 may result from a decreased peripheral metabolism of thyroid hormones due to the aging process itself and/or disease and may reflect a catabolic state. Low serum FT4 is associated with a better 4-yr survival; this may reflect an adaptive mechanism to prevent excessive catabolism.

To determine differences in physical activity level and functional fitness between young elderly (60-69 years) and old elderly (70-80 years) people with the hypothesis that an age-related decline would be found. A total of 1288 participants' level of physical activity was evaluated using the International Physical Activity Questionnaire: 594 were male (mean ± standard deviation: body height 175.62 ± 9.78 cm; body weight 82.26 ± 31.33 kg) and 694 female (mean ± standard deviation: body height 165.17 ± 23.12 cm; body weight 69.74 ± 12.44 kg). Functional fitness was also estimated using the Senior Fitness Test: back scratch, chair sit and reach, 8-foot up and go, chair stand up for 30 seconds, arm curl, and 2-minute step test. Significant differences (P < 0.05) were found for all Senior Fitness tests between young elderly (60-69 years) and old elderly (70-80) men. Similar results were found for the women, except no significant differences were found for the chair sit and reach and the 2-minute step test. From the viewpoint of energy consumption estimated by the International Physical Activity Questionnaire, moderate physical activity is dominant. In addition, with aging, among men and women older than 60 years, the value of the Metabolic Equivalent of Task in total physical activity significantly reduces (P < 0.05). This study found that the reduction in physical activity level and functional fitness was equal for both men and women and was due to the aging process. These differences between young and old elderly people were due to the reduction of muscle strength in both upper and lower limbs and changes in body-fat percentage, flexibility, agility, and endurance.

Low bone density as assessed by calcaneal ultrasound has been associated with mortality in elderly men and women. We examined the relationship between bone density measured at the hip and all cause and cardiovascular mortality in elderly men. Men aged 65-76 years from the general community were recruited from general practices in Cambridge between 1991 and 1995. At baseline survey, data collection included health questionnaires, measures of anthropometry and cardiovascular risk factors, as well as bone mineral density (BMD) measured using dual energy X-ray absorptiometry. All men have been followed up for vital status up to December 1999. BMD was significantly inversely related to mortality from all causes and cardiovascular disease, with decreasing rates with increasing bone density quartile, and an approximate halving of risk between the bottom and top quartile (p < 0.002, test for trend all causes and p < 0.025, test for trend for cardiovascular deaths). In multivariate analyses using the Cox proportional hazards model, an increase of 1 standard deviation (0.144 g/cm2) in total hip bone density was significantly associated with an age-adjusted 0.77 relative risk (95% CI 0.66-0.91) for all-cause mortality and 0.76 relative risk (95% CI 0.62-0.93) for cardiovascular disease mortality. The association remained significant after adjusting for age, body mass index, cigarette smoking status, serum cholesterol, systolic blood pressure, past history of heart attack, stroke or cancer and other lifestyle factors which included use of alcohol, physical activity and general health status. Low bone density at the hip is thus a strong and independent predictor of all-cause and cardiovascular mortality in older men.

The Sertoli cells of the testes secrete anti-Müllerian hormone (Müllerian inhibiting Substance, AMH) and inhibin B (InhB). AMH triggers the degeneration of the uterine precursor in male embryos, whereas InhB is part of the gonadal-pituitary axis for the regulation of sperm production in adults. However, both hormones are also putative regulators of homeostasis, and age-related changes in these hormones may therefore be important to the health status of elderly men. The levels of AMH in elderly men are unknown, with limited information being available about age-related changes in InhB. We have therefore used ELISAs to measure Sertoli cell hormone levels in 3 cohorts of community-dwelling men in New Zealand. In total, 615 men were examined, 493 of which were aged 65 or older. Serum AMH and InhB levels inversely correlated with age in men older than 50 years (p<0.001) but not in the younger men. A minority of elderly men had undetectable levels of AMH and InhB. The variation in hormone levels between similarly aged men increased with the age of men. AMH and InhB partially correlated with each other as expected (r = 0.48, p<0.001). However, the ratio of the two Sertoli hormones varied significantly between men, with this variation increasing with age. Elderly men selected for the absence of cardiovascular disease had AMH levels similar to those of young men whereas their InhB levels did not differ from aged-matched controls. These data suggests that Sertoli cell number and function changes with age, but with the extent and nature of the changes varying between men. PMID:23940675

Background In Japan, the incidence of kidney stones has increased markedly in recent decades. Major causes of kidney stones remain unclear, and limited data are available on the relationship between overweight/obesity and the incidence of kidney stones. We therefore evaluated body mass index (BMI) and the incidence of kidney stones in Japanese men. Methods Of the workers at a gas company, 5984 males aged 20–40 years underwent a medical examination in 1985 (baseline). This study includes 4074 of the men, who were free of kidney stones at baseline and underwent a second medical examination performed between April 2004 and March 2005. BMI was calculated from measured height and weight in 1985, and men were categorized into tertiles. The development of kidney stones during follow-up was based on self-reports from questionnaires at the second medical examination. Results The average duration of follow-up was 19 years, with 258 participants developing kidney stones during this period. Using the lowest BMI (1st tertile) group as a reference, the hazard ratios (95% confidence intervals [CIs]) for the 2nd and 3rd BMI tertiles were: 1.26 (95% CI, 0.92–1.73) and 1.44 (95% CI, 1.06–1.96), respectively (P for trend = 0.019). After additionally adjusting for potential confounders, such as age, systolic blood pressure, cardiorespiratory fitness, cigarette smoking, and alcohol consumption, the hazard ratios were 1.28 (95% CI, 0.93–1.76) and 1.41 (95% CI, 1.02–1.97), respectively (P for trend = 0.041). Conclusions These results suggest that increased BMI is a risk factor for kidney stones in Japanese men. PMID:26616396

In the adult, subclinical hyperthyroidism (Shyper) may alter skeletal muscle mass and strength. However, whether these effects are present in elderly subjects is not known. We explored the relationship between mild hyperthyroidism and physical function in a population-based sample of older persons. In a cross-sectional analysis, calf muscle cross-sectional area (CMA), handgrip strength, nerve conduction velocity (NCV), and Short Physical Performance Battery (SPPB) scores were compared between 364 euthyroid (Eut) and 28 Shyper men as well as between 502 Eut and 39 Shyper women. In a longitudinal analysis, we evaluated the relationship between baseline plasma TSH, FT3 and FT4 and the 3-year change in SPPB score in 304 men and 409 women who were euthyroid at enrolment. At the cross-sectional analysis, Shyper men, but not women, had a significantly (p = 0.02) lower SPPB score than Eut controls, although with comparable CMA, grip strength and NCV, and were more likely to have poor physical performance (odds ratio = 2.97, p < 0.05). Longitudinal analysis showed that in Eut men higher baseline FT4 was significantly (p = 0.02) predictive of a lower SPPB score at the 3-year follow-up. Even a modest thyroid hormone excess is associated with a reduced physical function in elderly men.

Studies of iron overload in humans and animals suggest that brain iron concentrations may be related in a regionally specific way to body iron status. However, few quantitative studies have investigated the associations between peripheral and regional brain iron in a normal elderly cohort. To examine these relationships, we used MRI to measure the proton transverse relaxation rate (R(2)) in 13 gray and white matter brain regions in 18 elderly men (average age, 75.5 years) with normal cognition. Brain R(2) values were compared with liver iron concentrations measured using the FerriScan MRI technique and serum iron indices. R(2) values in high-iron gray matter regions were significantly correlated (positively) with liver iron concentrations (globus pallidus, ventral pallidum) and serum transferrin saturation (caudate nucleus, globus pallidus, putamen) measured concurrently with brain R(2), and with serum iron concentrations (caudate nucleus, globus pallidus) measured three years before the current study. Our results suggest that iron levels in specific gray matter brain regions are influenced by systemic iron status in elderly men.

The aim of this study was to determine the relationship between reduced muscle mass (sarcopenia) and areal bone mineral density (BMD(a)) in middle-aged and elderly community-dwelling European men. Men with sarcopenia had significantly lower BMD(a) and were more likely to have osteoporosis compared with men without sarcopenia. In men, the relationship between reduced muscle mass (sarcopenia) and BMD(a) is unclear. This study aimed to determine this relationship in middle-aged and elderly community-dwelling men. Men aged 40-79 years from the Manchester (UK) and Leuven (Belgium) cohorts of the European Male Ageing Study were invited to attend for assessment including dual-energy X-ray absorptiometry, from which appendicular lean mass (aLM), fat mass (FM) and whole-body, spine and hip BMD(a) were determined. Relative appendicular skeletal muscle mass (RASM) was calculated as aLM/height². Muscle strength was assessed in subjects from Leuven. Sarcopenia was defined by RASM at <7.26 kg/m² and by the recent definition of the European Working Group on Sarcopenia in Older People (RASM at <7.26 kg/m(2) plus low muscle function). Linear regression was used to determine the associations between aLM, FM, muscle strength and BMD(a) and logistic regression to determine the association between sarcopenia and osteoporosis. Six hundred seventy-nine men with a mean age of 59.6 (SD = 10.7), contributed data to the analysis; 11.9 % were sarcopenic by the conventional definition. After adjustment for age and centre, aLM, RASM and FM were positively associated with BMD(a). Men with RASM at <7.26 kg/m² had significantly lower BMD(a) compared with those with RASM at ≥7.26 kg/m(2). In a multivariable model, aLM was most consistently associated with BMD(a). Men with sarcopenia were more likely to have osteoporosis compared with those with normal RASM (odds ratio = 3.0; 95 % CI = 1.6-5.8). Sarcopenia is associated with low BMD(a) and osteoporosis in middle-aged and

Although previous studies have analyzed the relationship between renal function and coronary artery calcification (CAC) in pre-dialysis and dialysis patients, limited studies have discussed the relationship between renal function and CAC in Chinese elderly men without obvious damage of renal function. The present study was designed to explore the relationship between renal function and CAC in Chinese elderly men without obvious damage of renal function. This cross-sectional study was carried out in 105 male participants older than 60 years with glomerular filtration rate (GFR) ≥ 45 ml/min/1.73 m 2 . CAC was detected by high-definition computerized tomography (HDCT), which is a highly sensitive technique for detecting the CAC and provides the most accurate CAC scores up to date. Age was 72 ± 8.4 years on average and ranged from 60 to 89 years. Simple correlation analysis indicated that all kinds of CAC scores including the Agatston, volume and mass scores inversely correlated with GFR values (p < 0.05 for all). In multivariate linear regression analysis, GFR values were independently associated with all these CAC scores (p < 0.05 for all). Renal function had an independent relationship with CAC detected by HDCT in Chinese elderly men, demonstrating that the relationship between renal function and CAC started at the early stage of renal function decline.

Human papillomavirus (HPV) infection is known to cause anal condyloma acuminatum (CA) and squamous cell carcinoma. Men who have sex with men (MSM) with HIV infection are frequently co-infected with HPV, especially high risk HPV (HR-HPV) that causes anal squamous cell carcinoma. However, there are few reports of HPV genotype studies in anal lesion of Japanese men. We tried to estimate the distribution of HPV genotypes in anal CA tissue specimens from the Japanese men to elucidate the risk of anal cancer. A total of 62 patients who had anal CA surgically excised were enrolled. They included 27 HIV-positive MSM, 18 HIV-negative MSM, 1 HIV-positive man who have sex with women (MSW), and 16 HIV-negative MSW. HPV genotypes in anal CA tissue were determined by the polymerase chain reaction technique with reverse line blot hybridization. HR-HPV was detected in 45.2% of the CA tissue specimens and high grade squamous intraepithelial lesion (HSIL) was observed in 15.3%. Moreover, the prevalence of HR-HPV in the HIV-positive MSM (70.4%) was higher than the HIV-negative MSM (33.3%, p = .0311) or the HIV-negative MSW (18.8%, p = .0016). The conditional logistic regression analysis suggested HIV positivity as the primary risk factor for the HR-HPV infection in CA. In addition, HSIL was detected in higher frequency in CA tissues from HIV-positive MSM (25.9%) than HIV-negative MSW (0.0%, p = .0346). HR-HPV and HSIL were frequently detected in anal CA tissues from Japanese MSM patients with HIV infection, suggesting the necessity of surveillance for this population.

We compared differences in intelligence and memory function between normal elderly Japanese subjects with more years of education and those with fewer years of education. We also investigated clinical and neuropsychological factors that are strongly correlated with memory function. There were 118 normal elderly subjects who underwent the Mini-Mental State Examination, Wechsler Adult Intelligence Scale, 3rd edition (WAIS-III), and Wechsler Memory Scale Revised. Subjects with at least 13 years of education were categorized as the H group, and those with 12 years of education or less were categorized as the L group. Age and Mini-Mental State Examination scores were not significantly different between the two groups. On the WAIS-III, there were significant differences between the two groups in Verbal IQ and Full Scale IQ. On the Wechsler Memory Scale Revised, there were significant differences between the two groups in Visual Memory, General Memory, and Delayed Recall. Correlation coefficients between memory function and the other factors demonstrated significant but weak correlations between years of education and General Memory (R = 0.22) and between years of education and Delayed Recall (R = 0.20). Strong correlations were found between Verbal IQ and Verbal Memory (R = 0.45), between Verbal IQ and General Memory (R = 0.49), between Full Scale IQ and General Memory (R = 0.50) and between Full Scale IQ and Delayed Recall (R = 0.48). In normal elderly Japanese subjects, years of education weakly correlated with memory function while Verbal IQ, Full Scale IQ and Verbal Comprehension on WAIS-III had stronger correlations with memory function. Verbal IQ and Verbal Comprehension on WAIS-III were found to be insusceptible to the cognitive decline characteristic of Alzheimer's disease or amnestic mild cognitive impairment. Therefore, verbal intelligence, as measured by Verbal IQ and Verbal Comprehension, may be the most useful factor for inferring premorbid memory function

To evaluate the association of low-density lipoprotein, high-density lipoprotein and non-high-density lipoprotein cholesterol with the risk of stroke, diabetes-related vascular events and mortality in elderly diabetes patients. This study was carried out as a post-hoc landmark analysis of a randomized, controlled, multicenter, prospective intervention trial. We included 1173 elderly type 2 diabetes patients (aged ≥ 65 years) from 39 Japanese institutions who were enrolled in the Japanese elderly diabetes intervention trial study and who could be followed up for 1 year. A landmark survival analysis was carried out in which follow up was set to start 1 year after the initial time of entry. During 6 years of follow up, there were 38 cardiovascular events, 50 strokes, 21 diabetes-related deaths and 113 diabetes-related events. High low-density lipoprotein cholesterol was associated with incident cardiovascular events, and high glycated hemoglobin was associated with strokes. After adjustment for possible covariables, non-high-density lipoprotein cholesterol showed a significant association with increased risk of stroke, diabetes-related mortality and total events. The adjusted hazard ratios (95% confidence intervals) of non-high-density lipoprotein cholesterol were 1.010 (1.001-1.018, P = 0.029) for stroke, 1.019 (1.007-1.031, P < 0.001) for diabetes-related death and 1.008 (1.002-1.014; P < 0.001) for total diabetes-related events. Higher non-high-density lipoprotein cholesterol was associated with an increased risk of stroke, diabetes-related mortality and total events in elderly diabetes patients. © 2012 Japan Geriatrics Society.

Introduction In the adult, subclinical hyperthyroidism (Shyper) may alter skeletal muscle mass and strength. However, whether these effects are present in elderly subjects is not known. We explored the relationship between mild hyperthyroidism and physical function in a population-based sample of older persons. Methods In a cross-sectional analysis, calf muscle cross-sectional area (CMA), handgrip strength, nerve conduction velocity (NCV), and Short Physical Performance Battery (SPPB) scores were compared between 364 euthyroid (Eut) and 28 Shyper men as well as between 502 Eut and 39 Shyper women. In a longitudinal analysis, we evaluated the relationship between baseline plasma TSH, FT3 and FT4 and the 3-year change in SPPB score in 304 men and 409 women who were euthyroid at enrolment. Results At the cross-sectional analysis, Shyper men, but not women, had a significantly (p = 0.02) lower SPPB score than Eut controls, although with comparable CMA, grip strength and NCV, and were more likely to have poor physical performance (odds ratio = 2.97, p< 0.05). Longitudinal analysis showed that in Eut men higher baseline FT4 was significantly (p=0.02) predictive of a lower SPPB score at the 3-year follow-up. Conclusion Even a modest thyroid hormone excess is associated with a reduced physical function in elderly men. PMID:21875391

Higher levels of serum uric acid are associated with an increased risk of cardiovascular diseases, which may be confounded by comorbidities. We investigated the effects of serum uric acid on the risk of hypertension in Japanese men at a worksite. We evaluated a total of 2335 Japanese male workers without hypertension who ranged in age from 18 to 64 years at a worksite in 2009. These men were followed for 6 years from 2009 to 2015. During the follow-up period, 380 individuals developed hypertension. The odds ratio for the incident hypertension was estimated according to quartiles of serum uric acid levels of 5.1 or less, 5.2-5.8, 5.9-6.6, and at least 6.7 mg/dl. The multivariable-adjusted risk of incident hypertension was significantly higher in the highest serum uric acid quartile than in the lowest: odds ratio 1.00 (reference) for the lowest quartile, 1.34 (0.91-1.97) for the second quartile, 1.42 (0.97-2.06) for the third quartile, and 1.65 (1.14-2.40) for the highest quartile. In stratified analyses, the association between serum uric acid and incident hypertension was significant in the patients of aged below 45 years and without comorbidities, namely diabetes and low levels of high-density lipoprotein-cholesterol. Serum uric acid levels were associated with the future incidence of hypertension, and the association was observed in the younger individuals, those without diabetes, and those with preserved high-density lipoprotein cholesterol levels in a worksite population of Japanese men.

Pulse wave velocity (PWV) is a simple and valid clinical method for assessing arterial stiffness. Coronary artery calcification (CAC) is an intermediate stage in the process leading to overt cardiovascular disease (CVD) and an established determinant of coronary artery disease. This study aimed to examine the association between PWV and CAC in a population-based sample of Japanese men. This is a cross-sectional study of 986 randomly selected men aged 40-79 years from Shiga, Japan. CVD-free participants were examined from 2006 to 2008. Brachial-ankle PWV (baPWV) was measured using an automatic waveform analyzer. CAC was assessed using computed tomography. Agatston scores ≥ 10 were defined as the presence of CAC. Prevalence of CAC progressively increased with rising levels of baPWV: 20.6%, 41.7%, 56.3%, and 66.7% across baPWV quartiles ＜ 1378, 1378-1563, 1564-1849, and ＞ 1849 cm/s (P ＜ 0.001 for trend). Associations remained significant after adjusting for age and other factors, including body mass index, systolic blood pressure, pulse rate, total and high-density lipoprotein cholesterol, hemoglobin A1c, drinking, smoking and exercise status, and the use of medication to treat hypertension, dyslipidemia and diabetes (P=0.042 for trend). The optimal cutoff level of baPWV to detect CAC was 1612 cm/s using receiver operating characteristic curve analysis. Arterial stiffness as defined by an elevated baPWV is associated with an increased prevalence of CAC in a general population-based setting among Japanese men.

The aims are to examine whether changes in body weight (dBW) are associated with changes in cardiovascular risk factors in Japanese men without abdominal obesity (waist circumference (WC) < 85 cm) and which anthropometric index, dBW or changes in WC (dWC), is more strongly associated with changes in cardiovascular risk factors in men without abdominal obesity. It is a retrospective study in 692 Japanese men without abdominal obesity who took annual health screening tests consecutively over one year. Standardized linear regression coefficients (SRCs) of dBW and dWC were calculated for changes in systolic blood pressure (dSBP), diastolic blood pressure (dDBP), fasting plasma glucose (dFPG), triglycerides (dTG), HDL cholesterol (dHDL), and high-sensitivity C-reactive protein (dCRP). The SRCs of dBW for dFPG and dHDL were significant in all men and in men with each risk factor corresponding to the component of metabolic syndrome (MetS). The SRCs of dWC for dTG and dCRP were significant in all men but not in men with each risk factor corresponding to the MetS component. In conclusions, dBW were significantly associated with dFPG and dHDL in Japanese men without abdominal obesity. Therefore, abdominal obesity should not be considered as a necessary component of MetS in Japanese men. dBW may be more useful than dWC as a marker of changes in cardiovascular risk factors in lifestyle intervention programs.

In 1997 we examined the prevalence of dementia among the Japanese elderly immigrants living in the São Paulo metropolitan area (n=166). Herein, we followed up on these subjects for causes of death and dementia incidence. We were able to contact 108 subjects: 54 were already dead. The most common cause of death was cardiac disease. For dementia, 31.6% of the dead subjects were found to have developed dementia before they died, and 20.8 % of the living subjects were demented. As for the baseline the clinical dementia rating (CDR), 20.8 % of CDR 0 and 50.0 % of CDR 0.5 subjects developed dementia in the dead group; whereas in the living group, 23.9 % of CDR 0 and 52.6 % of CDR 0.5 developed dementia. As a whole, the incidence was 34.2 ‰ per 1000 person-years. Cardiac disease as the most common cause of death was probably due to the higher prevalence of diabetes mellitus. Compared with the previous study, the lower incidence of dementia from the CDR 0.5 group may have been due to a higher mortality rate. This is the first study on the incidence of dementia in elderly Japanese immigrants in Brazil. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

A population-based cohort of 444 elderly men (mean ± SD age 80.2 ± 3.5 years) was investigated. Bone microstructure was measured by high-resolution peripheral quantitative computed tomography, areal BMD by dual-energy X-ray absorptiometry and serum 25-hydroxyvitamin D and parathyroid hormone levels by immunoassay. Mean cortical porosity at the distal tibia was 14.7% higher (12.5 ± 4.3% vs. 10.9 ± 4.1%, P < 0.05) whilst cortical volumetric BMD, area, trabecular bone volume fraction and femoral neck areal BMD were lower in men in the lowest quartile of vitamin D levels compared to the highest. In men with vitamin D deficiency (<25 nmol L -1 ) or insufficiency [25-49 nmol L -1 , in combination with an elevated serum level of parathyroid hormone (>6.8 pmol L -1 )], cortical porosity was 17.2% higher than in vitamin D-sufficient men (P < 0.01). A linear regression model including age, weight, height, daily calcium intake, physical activity, smoking vitamin D supplementation and parathyroid hormone showed that 25-hydroxyvitamin D independently predicted cortical porosity (standardized β = -0.110, R 2 = 1.1%, P = 0.024), area (β = 0.123, R 2 = 1.4%, P = 0.007) and cortical volumetric BMD (β = 0.125, R 2 = 1.4%, P = 0.007) of the tibia as well as areal BMD of the femoral neck (β = 0.102, R 2 = 0.9%, P = 0.04). Serum vitamin D is associated with cortical porosity, area and density, indicating that bone fragility as a result of low vitamin D could be due to changes in cortical bone microstructure and geometry. © 2016 The Authors.

Background The prevalence of low testosterone levels in men increases with age, as does the prevalence of decreased mobility, sexual function, self-perceived vitality, cognitive abilities, bone mineral density, and glucose tolerance, and of increased anemia and coronary artery disease. Similar changes occur in men who have low serum testosterone concentrations due to known pituitary or testicular disease, and testosterone treatment improves the abnormalities. Prior studies of the effect of testosterone treatment in elderly men, however, have produced equivocal results. Purpose To describe a coordinated set of clinical trials designed to avoid the pitfalls of prior studies and determine definitively if testosterone treatment of elderly men with low testosterone is efficacious in improving symptoms and objective measures of age-associated conditions. Methods We present the scientific and clinical rationale for the decisions made in the design of this trial. Results We designed The Testosterone Trials as a coordinated set of seven trials to determine if testosterone treatment of elderly men with low serum testosterone concentrations and also symptoms and objective evidence of impaired mobility and/or diminished libido and/or reduced vitality would be efficacious in improving mobility (Physical Function Trial), sexual function (Sexual Function Trial), fatigue (Vitality Trial), cognitive function (Cognitive Function Trial), hemoglobin (Anemia Trial), bone density (Bone Trial), and coronary artery plaque volume (Cardiovascular Trial). The scientific advantages of this coordination were common eligibility criteria, treatment and monitoring and the ability to pool safety data. The logistical advantages were a single steering committee, data coordinating center and data safety monitoring board (DSMB), the same clinical trial sites, and the possibility of men participating in multiple trials. The major consideration in subject selection was setting the eligibility criterion

In this cross-sectional study based on Korean elderly men and women, heavy alcohol intake for men was related to low whole-body BMD and light alcohol intake for women was associated with high whole-body, lumbar, and total femur BMD. Alcohol is a risk factor of osteoporosis but previous studies on its effect on bone health has been controversial. The aim of this study was to evaluate the association between alcohol intake and bone mineral density in Korean elderly men and women. Based on the Fourth and Fifth Korean National Health and Nutrition Examination Surveys (KNHANES), 2657 men and 2080 women 50 to 79 years of age were included. Bone mineral density (BMD) was measured using dual energy X-ray absorptiometry (DXA). Alcohol consumption was determined by self-administered questionnaires and classified into four groups according to sex: non-drinkers (0 g/day), light drinking (1-19 g/day men, 1-9 g/day women), moderate drinking (20-39 g/day men, 10-29 g/day women), and heavy drinking (≥ 40 g/day men, ≥ 20 g/day women). The adjusted mean values calculated by linear regression analysis for BMD were determined according to the amount of alcohol consumed. Light drinkers had the highest whole-body BMD for both men (mean 1.164, SD 0.047-1.281) and women (mean 1.046, SD 0.912-1.180). Among men, mean whole-body BMD for heavy drinkers was significantly lower than that among light drinkers (P = 0.031). Among women, BMD for light drinkers was significantly higher in the whole body, lumbar, and total femur than that for non-drinkers (P < 0.001, P = 0.026, P = 0.040, respectively). Heavy alcohol intake may be associated with lower BMD in men while light alcohol intake may associate with higher BMD among women. Future longitudinal studies investigating the effect of alcohol consumption on bone mineral density are needed to validate the findings of this study.

Japan has been experiencing low fertility for many years. In this study, I investigated the relationship between gender role attitudes and fertility intentions among Japanese single men and women of reproductive ages. Utilizing the Longitudinal Survey of Adults in the 21st Century data, 8944 men and 7924 women aged 20-34 years with single, childless status were analyzed. Gender role attitudes were assessed by participants' preferences for the division of labor between a man and a woman: income earning, housework, and childcare. Those who preferred men to earn income and women to perform housework and childcare were considered to have traditional attitudes, whereas those who preferred women and men to share these responsibilities were considered to have egalitarian attitudes. Outcomes were fertility intentions measured by a desire to have children and ideal number of children. Logistic regression analyses were conducted. Egalitarian attitudes about income earning and housework were associated with low fertility intentions (a lesser desire for children) compared to traditional attitudes: adjusted odds ratios were 1.56 [1.36, 1.80] for men and 1.47 [1.26, 1.72] for women with income earning. Men's preference for sharing childcare responsibility was associated with high fertility intentions. Japanese society has not shifted away from the traditional division of labor despite the increase in female labor force participation. Low fertility intentions among Japanese men and women with egalitarian attitudes suggest that institutional support for balancing work and family may be necessary to improve the low fertility trend.

Chowdhary, U

1989-06-01

70 interested elderly (65 yr. and over) men and women participated in an investigation of older consumers' apparel-shopping behavior and satisfactions and dissatisfactions with available clothing and facilities. Analysis showed that the participants considered shopping ease, wide variety, and label/brand as some of the important factors while shopping for clothes. The respondents were satisfied with good selection, closeness of the mall, and reasonable sales. However, their dissatisfactions ranged from service to fit and size, youthful styles, and abundance of imported clothing. In-store displays, mail order catalogs, and window shopping were the most commonly used sources of apparel information. Several implications of the findings were discussed and suggestions for further research were made.

The risk of prostate cancer-specific mortality (PCSM) in healthy elderly men may depend on extent of treatment. The authors of this report compared the use of brachytherapy alone with combined brachytherapy, external-beam radiation to the prostate and seminal vesicles, and androgen-suppression therapy (CMT) in this population. The study cohort comprised 764 men aged > or = 65 years with high-risk prostate cancer (T3 or T4N0M0, prostate-specific antigen >20 ng/mL, and/or Gleason score 8-10) who received either brachytherapy alone (n = 206) or CMT (n = 558) at the Chicago Prostate Cancer Center or at a 21st Century Oncology facility. Men either had no history of myocardial infarction (MI) or had a history of MI treated with a stent or surgical intervention. Fine and Gray regression analysis was used to identify the factors associated with PCSM. The median patient age was 73 years (interquartile range, 70-77 years). After a median follow-up of 4.9 years, 25 men died of prostate cancer. After adjusting for age and prostate cancer prognostic factors, the risk of PCSM was significantly less (adjusted hazard ratio, 0.29; 95% confidence interval, 0.12-0.68; P = .004) for men who received CMT than for men who received brachytherapy alone. Other factors that were associated significantly with an increased risk of PCSM included a Gleason score of 8 to 10 (P = .017). Elderly men who had high-risk prostate cancer without cardiovascular disease or with surgically corrected cardiovascular disease had a lower risk of PCSM when they received CMT than when they received brachytherapy alone. These results support aggressive locoregional treatment in healthy elderly men with high-risk prostate cancer. (c) 2010 American Cancer Society.

Objective The serum level of LOX-1 ligand containing ApoB (LAB) may reflect atherogenicity better than LDL cholesterol (LDLC), total LDL particles and usual measurement of oxidized LDL. The association between LAB and intima-media thickness (IMT) of carotid artery was investigated by ultrasound in US and Japan men. Methods Participants were 297 US Caucasian and 310 Japanese men, aged 40 to 49 years without past history of cardiovascular disease. Serum LAB levels were measured by ELISAs with recombinant LOX-1 and monoclonal anti–apolipoprotein B antibody. Results Serum LAB levels [median (interquartile range), μg/L] were 1,321 (936, 1730) in US Caucasians and 940 (688, 1259) in Japanese. For Caucasian men, average IMT was higher in higher LAB quartile, which was 0.653, 0.667, 0.688, and 0.702 mm, respectively (p for trend= 0.02). Linear regression analysis showed serum LAB was significantly associated with IMT after adjustment for LDLC or total LDL particles in addition to other traditional or novel risk factors for atherosclerosis such as C-reactive protein. However, there was no significant relationship between LAB and IMT in Japanese men. Conclusion Serum LAB, a new candidate biomarker for residual risk, was associated with an increased carotid IMT in US Caucasian men independently of various risk factors; however, ethnic difference should be clarified in the future.

Background Male pattern baldness (MPB), an observable trait, has been reported to be associated with various diseases, such as prostate cancer and cardiovascular disease. Oral sulfur-containing gases have also been suggested to be useful as markers of systemic health condition. However, there are no known reports regarding the associations among MPB, and oral sulfur-containing gases, and systemic health conditions in males. Methods We studied 170 male subjects aged either 60 or 65 years old. The degree of MPB was assessed using the Norwood-Hamilton Baldness scale. Oral sulfur-containing gases were measured using a compact-designed device. All subjects completed physical and laboratory blood examinations, a face-to-face medical questionnaire, and an oral examination. Results There were significant differences between the levels of CH3SCH3 and baldness patterns, independent of age. When we analyzed whether the association was linked to systemic health condition, a strong significant association was observed between the level of CH3SCH3 and severe MPB in subjects with gastrointestinal diseases, hypertension, and hypercholesterolemia. Conclusion These results suggest that MPB is associated with the level of CH3SCH3, a sulfur-containing gas that causes oral malodor, in elderly Japanese males. Further, the association was intensified by the existence of gastrointestinal tract and metabolic disorders. PMID:19284665

Background Cigarette smoking is a risk factor of coronary heart disease (CHD). Vascular calcification such as coronary artery calcium (CAC) and aortic calcium (AC) is associated with CHD. We hypothesized that cigarette smoking is associated with coronary artery and aortic calcifications in Japanese and Koreans with high smoking prevalence. Methods Random samples from populations of 313 Japanese and 302 Korean men aged 40 to 49 were examined for calcification of the coronary artery and aorta using electron beam computed tomography. Coronary artery calcium (CAC) and aortic calcium (AC) were quantified using the Agatston score. We examined the associations of cigarette smoking with CAC and AC after adjusting for conventional risk factors and alcohol consumption. Current and past smokers were combined and categorized into two groups using median pack-years as a cutoff point in each of Japanese and Koreans. The never smoker group was used as a reference for the multiple logistic regression analyses. Results The odds ratios of CAC (score ≥10) for smokers with higher pack-years were 2.9 in Japanese (P<0.05) and 1.3 in Koreans (non-significant) compared to never smokers. The odds ratios of AC (score ≥100) for smokers with higher pack-years were 10.4 in Japanese (P<0.05) and 3.6 in Koreans (P<0.05). Conclusion Cigarette smoking with higher pack-years is significantly associated with CAC and AC in Japanese men, while cigarette smoking with higher pack-years is significantly associated with AC but not significantly with CAC in Korean men.

We examined the relationship among the serum omega-3 and omega-6 fatty acid (O3FA and O6FA) levels, serum C-reactive protein (CRP) levels, and arterial stiffness/wave reflection (AS/WR) in healthy Japanese men. In 2206 Japanese healthy men, parameters related to the AS/WR (i.e., brachial-ankle pulse wave velocity and radial arterial pulse wave analysis) were measured. No significant inverse relationships were observed between the serum O3FA levels and the AS/WR-related parameters. Adjusted values of the AS/WR-related parameters and serum CRP levels were higher in the subjects with serum O6FA levels in the highest tertile than in those with serum O6FA levels in the lowest tertile. In healthy Japanese men with known high dietary intakes of O3FAs, the serum O3FA levels may not reflect the pathophysiological abnormalities related to AS/WR. Increased serum O6FA levels appeared to be independently associated with the unfavorable conditions related to AS/WR and inflammation. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Training induced adaptations in characteristics of postural reflexes in elderly men.

The aging neuromuscular system is affected by structural and functional changes which lead to a general slowing down of neuromuscular performance and an increased risk of falling. The impact of heavy resistance (HR) training in the elderly on maximum voluntary contraction (MVC) and rate of force development (RFD) has been investigated in the past. However, the influence of sensorimotor (SENSO) training and HR training on the ability to compensate for gait perturbations has not yet been investigated in the elderly. Therefore, the purpose of the study was to examine the impact of HR and SENSO training in elderly men on unexpected treadmill perturbations. Functional reflex activity was recorded by means of surface EMG in 40 male subjects (>60 years) before and after 13 weeks of HR and SENSO training and in another 20 male subjects (>60 years), which served as a CONTROL-group. SENSO training resulted in a decrease in onset latency, an enhanced reflex activity in the prime mover as well as a decrease in maximal angular velocity of the ankle joint complex during the perturbation impulses. No significant changes were observed in the HR- and in the CONTROL-group. The results clearly indicate that SENSO training has an impact on spinal motor control mechanisms in the elderly. Training induced improvements in perception and procession of afferent information could be a possible reason for the increase in reflex contraction. Due to these adaptive processes, SENSO training could be a well-suited method for fall preventive programs in elderly people.

Background The independent and combined associations of muscle strength and obesity on the prevalence of type 2 diabetes in Japanese men remain unclear. Methods Hand grip strength was cross-sectionally evaluated between 2011 and 2013 to assess muscle strength in 5039 male workers aged 40 to 64 years. Weight and height were measured, and overweight/obesity was defined as a body mass index ≥25 kg/m2. The prevalence of type 2 diabetes, defined as fasting plasma glucose ≥126 mg/dL and/or hemoglobin A1c ≥6.5% and/or self-reported physician-diagnosed diabetes, was evaluated. Odds ratios (OR) and 95% confidence intervals (95% CI) for the prevalence of type 2 diabetes were obtained using a logistic regression model. Results In total, 611 participants had type 2 diabetes, and 1763 participants were overweight/obese. After adjustment for covariates, we found an inverse association between muscle strength and the prevalence of type 2 diabetes (P for trend <0.01). In addition, when the analyses were stratified by obesity status, the multivariable-adjusted OR per 2-standard-deviation increase in muscle strength was 0.64 (95% CI, 0.49–0.83) in the overweight/obese group, compared to a weaker relationship in the normal-weight group (OR 0.79 per 2-standard-deviation increase; 95% CI, 0.60–1.06). Conclusions Dynapenia, an age-related decrease in muscle strength, is associated with increased prevalence of type 2 diabetes, and this relationship is stronger in overweight/obese middle-aged Japanese men than in normal-weight men.

Background Impaired renal function has been linked to cognitive impairment. We assessed mid-life proteinuria and late-life cognitive function in elderly Asian males. Methods The Honolulu Heart Program is a prospective study that began in 1965 with 8,006 Japanese-American men ages 45–68 years. Mid-life proteinuria was detected by urine dipstick in 1971–74. The Honolulu-Asia Aging Study began 20 years later, with cognitive assessment by the Cognitive Abilities Screening Instrument (CASI) in 3,734 men. Standard criteria were used to classify 8-year incident dementia and subtypes. RESULTS The age-adjusted incidence of dementia increased significantly from 13.8, to 22.8, to 39.7 per 1,000 person years follow-up, among those with no, trace and positive mid-life proteinuria, p=0.004. Using linear regression adjusting for age, education, APOEε4, stroke, hypertension, systolic blood pressure, diabetes, fasting blood glucose, physical activity and baseline CASI, those with positive proteinuria had significantly higher annual change in CASI over 8 years follow-up (−1.24, p=0.02), reference=no proteinuria. Multivariate Cox regression found positive proteinuria had a significant association with incident all-cause dementia (RR=2.66, 95%CI=1.09–6.53, p=0.03), but no significant associations with incident Alzheimer’s disease or vascular dementia. CONCLUSION Mid-life proteinuria was an independent predictor for late-life incident all-cause dementia and cognitive decline over 8 years. PMID:25626635

The Cognitive Abilities Screening Instrument (CASI) was designed for use in cross-cultural studies of Japanese and Japanese-American elderly in Japan and the U.S.A. The measurement equivalence in Japanese and English had not been confirmed in prior studies. We analyzed the 40 CASI items for differential item functioning (DIF) related to test language, as well as self-reported proficiency with written Japanese, age, and educational attainment in two large epidemiologic studies of Japanese-American elderly: the Kame Project (n=1708) and the Honolulu-Asia Aging Study (HAAS; n = 3148). DIF was present if the demographic groups differed in the probability of success on an item, after controlling for their underlying cognitive functioning ability. While seven CASI items had DIF related to language of testing in Kame (registration of one item; recall of one item; similes; judgment; repeating a phrase; reading and performing a command; and following a three-step instruction), the impact of DIF on participants' scores was minimal. Mean scores for Japanese and English speakers in Kame changed by <0.1 SD after accounting for DIF related to test language. In HAAS, insufficient numbers of participants were tested in Japanese to assess DIF related to test language. In both studies, DIF related to written Japanese proficiency, age, and educational attainment had minimal impact. To the extent that DIF could be assessed, the CASI appeared to meet the goal of measuring cognitive function equivalently in Japanese and English. Stratified data collection would be needed to confirm this conclusion. DIF assessment should be used in other studies with multiple language groups to confirm that measures function equivalently or, if not, form scores that account for DIF.

In order to compare the physiological and the subjective responses to low relative humidity of elderly and young men, we measured saccharin clearance time (SCT), frequency of blinking, hydration state of the skin, transepidermal water loss (TEWL), sebum level recovery and skin temperatures as physiological responses. We asked subjects to evaluate thermal, dryness and comfort sensations as subjective responses using a rating scale. Eight non-smoking healthy male students (21.7+/-0.8 yr) and eight non-smoking healthy elderly men (71.1+/-4.1 yr) were selected. The pre-room conditions were maintained at an air temperature (Ta) of 25 degrees C and a relative humidity (RH) of 50%. The test-room conditions were adjusted to provide 25 degrees C Ta and RH levels of 10%, 30% and 50%. RH had no effect on the activity of the sebaceous gland or change of mean skin temperature. SCT of the elderly group under 10% RH was significantly longer than that of the young group. In particular, considering the SCT change, the nasal mucous membrane seems to be affected more in the elderly than in the young in low RH. Under 30% RH, the eyes and skin become dry, and under 10% RH the nasal mucous membrane becomes dry as well as the eyes and skin. These findings suggested that to avoid dryness of the eyes and skin, it is necessary to maintain greater than 30% RH, and to avoid dryness of the nasal mucous membrane, it is necessary to maintain greater than 10% RH. On the thermal sensation of the legs, at the lower humidity level, the elderly group felt cooler than the young group. On the dry sensation of the eyes and throat, the young group felt drier than the elderly group at the lower humidity levels. From the above results, the elderly group had difficulty in feeling dryness in the nasal mucous membrane despite being easily affected by low humidity. On the other hand, the young group felt the change of humidity sensitively despite not being severely affected by low humidity. Ocular mucosa and

Air displacement plethysmography with the BOD-POD is a new densitometry technique, and has been found to be an accurate method to measure body composition. The aim of this study was to assess body composition in a group of free living healthy subjects 60 years of age or older from a rural area of Northwest Mexico, and to evaluate body composition by anthropometry and bioelectrical impedance (BIA) using equations reported for other elderly populations. Body composition was evaluated in 21 women and 26 men with the BOD-POD, by anthropometry, and BIA and compared to different equations using the Bland- Altman procedure. Body fat in elderly women and men was 42.7 and 30.2 % respectively. In women, Segal's equation using BIA 1, based on standing height, showed no significant differences with the BOD-POD. There was satisfactory agreement between Segal's equation and BOD-POD. In men similar results was found with Deurenberg's equation using B1A 2 based on recumbent length. Segal's and Deurenberg's equations were accurate and precise for the estimation of body fat in the elderly of this study. The use of these equations could improve the estimation of body composition for similar elderly subjects. Further studies are recommended with a larger size samples to include elderly subjects from other Latin American countries.

Sarcopenia might be associated with bone fragility in elderly individuals. This study aimed to investigate the prevalence of sarcopenia and its association with fragility fracture sites in elderly Chinese patients. Patients (322 men and 435 women) aged 65-94 years and with a history of fragility fractures in the ankle, wrist, vertebrae or hip, and healthy men (n = 1263) and women (n = 1057) aged 65-92 years without a history of fractures were enrolled. Whole-body dual energy X-ray absorptiometry was used to analyze skeletal muscle mass index (SMI), fat mass and bone mineral density. Sarcopenia was defined as SMI less than two standard deviations below the mean of a young reference group. Sarcopenia occurrence varied with fracture location. Sarcopenia was more common in females with vertebral and hip fractures and in men with hip and ankle fractures than in the non-fracture group). Sarcopenia was significantly more prevalent in men with wrist, hip and ankle fractures than in women. SMI was correlated with BMD in different fracture groups. Logistic regression analyses revealed that lower SMI was associated with an increased risk of hip fracture both in men and women and ankle fracture in men. Sarcopenia may be an independent risk factor for hip and ankle fractures in men, and for hip fractures in women.

No previous study has satisfactorily clarified the nature of sleep in elderly bedridden people with disorders of consciousness (DOC). The objective of the present study was to clarify the sleep states of 10 elderly bedridden patients with DOC in a Japanese hospital to facilitate provision of evidence-based nursing care and appropriate adjustment of patients' environments. Nocturnal polysomnography recordings were analyzed according to the standard scoring criteria, and the patients' sleep stages and quality were investigated. Of the 10 patients, 9 showed slow wave sleep (SWS), 4 showed very high values for sleep efficiency (96-100%), and in 3 of these patients, the percentage of SWS was ≥ 20%. Furthermore, three of these four patients had 200 or more changes in sleep stage. Although the mechanism is unknown, the amount of SWS combined with the value of sleep efficiency suggests that the quality of sleep is poor in elderly bedridden patients with DOC. Further study is needed to determine better indicators of good sleep in this population. © The Author(s) 2014.

This study examines the acculturation effects on metabolic syndrome (MetS), and its related factors, among immigrant Japanese-Brazilian men in Japan. Quantitative and qualitative approaches were utilized. In the quantitative study (n = 149), multiple logistic regression analyses estimated the impact of length of residence and arrival age on MetS. For the qualitative study, five focus group discussions were conducted with participants (n = 26) from the quantitative study sample. The oldest arrival age group was more likely to have MetS (OR, 95% CI 4.41, 1.09-17.78) after adjusting for covariates; whereas, length of residence had no association with MetS. The oldest arrival age group, with shorter residence period, was also associated with increased MetS prevalence. Qualitative results identified participants' Brazilian dietary habits as being potential risk factors for MetS. Japanese-Brazilian immigrant men with older arrival age in Japan were more likely to suffer from MetS, especially shortly after arrival.

An 81-year-old Japanese man presented with constitutional symptoms and anemia and was diagnosed with giant cell arteritis (GCA) and myelodysplastic syndrome (MDS) simultaneously. His symptoms and anemia improved promptly with steroids; however, the MDS rapidly progressed to overt leukemia. While MDS patients are at an increased risk of autoimmune diseases, an association with GCA has rarely been reported. This case illustrates the importance of considering GCA as a cause of anemia in elderly patients if MDS is already diagnosed, even in countries where the prevalence of GCA is very low. The simultaneous development of GCA and MDS suggests a common pathogenetic link between these two diseases.

Background The objective of this study was to retrospectively review oncological outcomes in patients with stage I testicular germ cell tumor (GCT). Patients and Methods This study included 265 consecutive Japanese men undergoing orchiectomy for stage I testicular GCT, and a retrospective review of their records was performed. Results Of these 265 patients, 192 and 73 were pathologically classified with seminoma and nonseminoma, respectively. Prophylactic radiation and chemotherapy were performed in 62 patients with seminoma and 6 with nonseminoma, respectively. Disease recurrence occurred in 12 seminoma patients, of whom 11 had not received prophylactic radiation therapy; however, all 12 achieved a complete response to bleomycin, etoposide and cisplatin therapy. Of the nonseminoma patients, 19 experienced disease recurrence and were then treated with bleomycin, etoposide and cisplatin followed additionally by the surgical resection of residual tumors and salvage chemotherapy in 7 and 4, respectively. There was no cancer-specific death in the 265 patients, and 5-year recurrence-free survival rates in patients with seminoma and nonseminoma were 92.6 and 72.8%, respectively. Furthermore, following factors appeared to be significantly associated with recurrence-free survival in these patients: age, T classification, microvascular invasion and adjuvant therapy for those with seminoma, and microvascular invasion for those with nonseminoma. Conclusions Despite a generally favorable prognosis in Japanese men with stage I testicular GCT, intensive follow-up or prophylactic therapy should be considered for men with possible risk factors of disease recurrence.

Saudi demographic composition has changed because of increased life expectancy and decreased fertility rates. Little data are available about health conditions among older adults in Saudi Arabia, who are expected to represent 20% of the population by 2050. The study aim was to assess the prevalence and risk factors for chronic conditions among older Saudi men. The sample pertained to 400 men (age ≥55 years) from Buraidah, Al-Qassim. Research assistants recruited participants in all the mosques from the randomly selected neighborhoods (16 of 95). They administered a structured questionnaire that assessed self-reported disease history (heart disease, hypertension, diabetes, asthma, gastric/peptic ulcer, and cancer), and medication use; participants' height, weight, blood pressure, and random blood glucose (glucometer) were measured. Multinomial logistic regressions were employed to assess correlates of number of chronic diseases. The mean and standard deviation for age and body mass index (BMI) were 63.0 ± 7.5 years and 28.9 ± 4.8 (kg/m 2 ), respectively. 78% (77.8%) were overweight or obese, 35.0% were employed, 54.5% walked daily, 9.3% were current smokers, and 85.0% belonged to the middle class. The prevalence of hypertension, diabetes, heart disease, asthma, ulcer, and cancer were: 71.3% 27.3%, 16.4%, 9.7%, 8.9%, and 2.0%, respectively. Of the participants, 31.0% had one, 34.5% had two or more, and 34.5% did not have any chronic diseases. The likelihood of chronic diseases increased with increased age, higher BMI, and current smoking. The chronic disease prevalence among the Saudi elderly men is substantial.

To investigate the rates of attempted suicide and its association with psychological distress, experiences of bullying and verbal harassment, and demographic characteristics among Japanese homosexual, bisexual or other men questioning their sexual orientation. A cross-sectional design using Japanese participants recruited through the internet. Of the 1025 respondents, 154 (15%) of the men reported a history of attempted suicide, 716 (70%) showed high levels of anxiety and 133 (13%) showed high levels of depression. 851 (83%) experienced school bullying and 615 (60%) were verbally harassed because of being perceived by others as homosexual. Independent correlates of attempted suicide were psychological distress, history of being verbally harassed, history of sex with a woman, history of meeting a male through the internet, disclosing sexual orientation to six or more friends and not having a university degree. Mental health services and prevention programmes are needed to deal with the psychological consequences of social stigma for Japanese men who are homosexual, bisexual or questioning their sexual orientation.

Low skeletal muscle mass is associated with poor structural parameters of bone and impaired balance in elderly men--the MINOS study.

In 796 men, 50-85 years of age, decreased relative skeletal muscle mass index was associated with narrower bones, thinner cortices, and a consequent decreased bending strength (lower section modulus), as well as with impaired balance and an increased risk of falls. In men, appendicular skeletal muscle mass (ASM) is correlated positively with BMC and areal BMD (aBMD). In elderly men, low muscle mass and strength (sarcopenia) is associated with difficulties in daily living activities. The aim of this study was to evaluate if ASM is correlated with bone size, mechanical properties of bones, balance, and risk of falls in elderly men. This study used 796 men, 50-85 years of age, belonging to the MINOS cohort. Lifestyle factors were evaluated by standardized questionnaires. Estimates of mechanical bone properties were derived from aBMD measured by DXA. ASM was estimated by DXA. The relative skeletal muscle mass index (RASM) was calculated as ASM/(body height)(2.3). After adjustment for age, body size, tobacco smoking, professional physical activity, and 17beta-estradiol concentration, RASM was correlated positively with BMC, aBMD, external diameter, and cortical thickness (r = 0.17-0.34, p < 0.0001) but not with volumetric BMD. Consequently, RASM was correlated with section modulus (r = 0.29-0.39, p < 0.0001). Men in the lowest quartile of RASM had section modulus of femoral neck and distal radius lower by 12-18% in comparison with men in the highest quartile of RASM. In contrast, bone width was not correlated with fat mass, reflecting the load of body weight (except for L(3)), which suggests that the muscular strain may exert a direct stimulatory effect on periosteal apposition. After adjustment for confounding variables, a decrease in RASM was associated with increased risk of falls and of inability to accomplish clinical tests of muscle strength, static balance, and dynamic balance (odds ratio per 1 SD decrease in RASM, 1.31-2.23; p < 0.05-0.001). In elderly men

Rapid population aging in Japan has led to rising demands for informal care giving. Traditionally, care giving for aging parents has fallen disproportionately on the shoulders of women living in multigenerational households. However, rising labor force participation by Japanese women, declining marriage and fertility rates, and women's changing expectations have combined to produce unprecedented strains on traditional multigenerational households where care giving to elders traditionally takes place. In this paper, we explored gender-specific relationships between family structure, stress and worries, and health behaviors, using linked data from two national surveys conducted in Japan: the 1995 Comprehensive Survey of the Living Conditions of People on Health and Welfare, and the 1995 National Nutrition Survey. We found that women in multigenerational households reported more care-giving worries, and also less future health and financial worries. Living with parents was associated with protective health behaviors (less smoking, less heavy drinking), but also more sedentary behavior among women, while men in "sandwich" families (i.e., living with both parents and children) reported heavier smoking. The association of family structure and health behavior was not mediated by worries. Living alone was associated with worse health for women. These findings suggest gender-specific patterns of worries and health behaviors that reflect both the health-protecting and health-damaging effects of living in multigenerational households.

The literature shows that there are important differences between women and men in the underlying mechanisms of transmission of HIV infection and AIDS, as well as in the social and economic consequences of HIV/AIDS. These stem from sexual behaviour and socially constructed 'gender' differences between women and men in roles and responsibilities. Despite the fact that numerous gender-related sociocultural factors influence HIV/AIDS protective behaviours, little gender specificity is included in HIV prevention among the elderly. In order to close this gap, this study explored gender-related perceptions of risk of HIV infection among elderly men and women of Ga-Rankuwa in Gauteng Province, South Africa. This qualitative study used purposive sampling to conduct three focus group interviews with 22 women and 10 men who were above 60 years of age. Findings revealed that both genders blame each other for the spreading of HIV/AIDS. Male participants displayed the tendency to have multiple partners, whereas females accepted that males are promiscuous. Mixed perceptions about disclosure of HIV status were found. Condom use was a challenge, as men did not know how to introduce it with their wives, and some female participants indicated that men are resistant to using condoms. The elderly men also believed that women will have sex in exchange for money. It is concluded that there is a need for substantial behaviour change among both elderly males and females, which should address gender power relations. More in-depth and extensive research in this area is recommended.

Supplementation studies have suggested a role of n-3 polyunsaturated fatty acids (PUFAs) in homocysteine metabolism, but the evidence is limited and inconsistent among studies that measured blood levels of n-3 and n-6 PUFAs. We examined the association between blood levels of PUFAs and homocysteine in Japanese men and women. The subjects were 496 employees (290 men and 206 women) of 2 municipal offices in Japan. Fatty acid composition in serum phospholipids and cholesterol ester (CE) was measured using gas-liquid chromatography. Multiple regression was used to calculate means of homocysteine concentrations according to PUFA tertile with adjustment for potential confounders. Serum homocysteine concentration decreased with increasing levels of total n-3 PUFA, eicosapentaenoic acid and docosahexaenoic acid (DHA) in serum phospholipids and CE with adjustment for age, sex and workplace. However, only DHA in serum phospholipids remained statistically significant after additional adjustment for other potential confounders including serum folate (P-trend = 0.04). N-6 PUFAs were not significantly associated with homocysteine concentrations. Higher proportion of DHA in serum phospholipids may be associated with lower homocysteine concentrations in Japanese men and women.

Health-related quality of life (HRQL) is an important measure of health outcome in working and healthy populations. Here, we investigated the impact of effort-reward imbalance (ERI), a representative work-stress model, on HRQL of Japanese working men. The study targeted 1,096 employees from a manufacturing plant in Japan. To assess HRQL and ERI, participants were surveyed using the Japanese version of the Short-Form 8 Health Survey (SF-8) and effort-reward imbalance model. Of the 1,096 employees, 1,057 provided valid responses to the questionnaire. For physical summary scores, the adjusted effort-reward imbalance odds ratios of middle vs. bottom and top vs. bottom tertiles were 0.24 (95% confidence interval, 0.08-0.70) and 0.09 (95% confidence interval, 0.03-0.28), respectively. For mental summary scores, ratios were 0.21 (95% confidence interval, 0.07-0.63) and 0.07 (95% confidence interval, 0.02-0.25), respectively. These findings demonstrate that effort-reward imbalance is independently associated with HRQL among Japanese employees.

The objective of this study was to characterise the status of health-related quality of life (HRQOL) in Japanese men with late-onset hypogonadism (LOH) treated with testosterone replacement therapy (TRT). HRQOL in 69 consecutive Japanese men with LOH undergoing TRT for at least 6 months was prospectively evaluated before and 6 months after the initiation of TRT using the Medical Outcomes Study 8-Item Short-Form Health Survey (SF-8). All eight-scale scores except for bodily pain (BP) in the 69 patients at 6 months after the introduction of TRT significantly improved compared with those before TRT; however, all scale scores except for BP in the 69 patients were significantly inferior to those in age-matched Japanese controls irrespective of the timing of SF-8. Multivariate analyses of several parameters revealed that both age and Aging Male Symptom (AMS) score had an independent impact on mental health (MH), despite the lack of an independent association between any score and the remaining factors examined. TRT appeared to significantly improve the status of HRQOL in men with LOH; however, even after the introduction of TRT, HRQOL associated with MH remained significantly impaired in elderly men and/or those with a high AMS score. © 2015 Blackwell Verlag GmbH.

Background and aim Senile prostatic enlargement due to benign prostatic hyperplasia (BPH) is a common problem among older men, and is responsible for considerable disability. This study was conducted to determine the prevalence and determinants of the clinically diagnosed prostatic enlargement among elderly men in Arar, Northern Saudi Arabia. Methods This cross-sectional study was carried out on all consented elderly males attending the outpatient clinic of the urology department of Arar Central Hospital from February 2017 to July 30, 2017. Each participant underwent a general examination and digital per rectal to detect general chronic diseases, obesity and prostatic enlargement. Data were analyzed by SPSS version 16, using descriptive statistics and Chi-squared test. Results Among 81 elderly male participants in the study, 19.8% had clinically diagnosed senile prostatic enlargement (SPE) and 3.7% had prostatic tumors. There was significant relation between SPE and age as 6.2% of cases were 60–69 years, 43.8% were 70–79 years and 44.0% were 80 years or more (p<0.05). There was also significant relation between SPE and obesity as 62.5% of cases were obese and 37.5% were non obese (p<0.05). There was no significant relation with marital status, smoking or diabetes mellitus (p<0.05). Conclusion Senile prostatic enlargement is one of the significant important issues in public health in Arar city, Northern Saudi Arabia. The prevalence of this condition reaches 19.3%, thereby placing even greater burden on the quality of life of the elderly and on the health system in the region. PMID:29038720

We prospectively examined the association between coffee consumption and the risk of developing colorectal cancer in a large population-based cohort study (the JPHC Study) of Japanese men and women. Data were analyzed from a population-based cohort of 96,162 subjects (46,023 men and 50,139 women). A total of 1,163 incident colorectal cancers were identified during the follow-up period, including 763 cases of colon cancer and 400 of rectal cancer. We observed a significant inverse association between coffee consumption and the risk of developing invasive colon cancer among women. Compared with those who almost never consumed coffee, women who regularly consumed 3 or more cups of coffee per day had a RR of 0.44 (95% CI = 0.19-1.04; p for trend = 0.04) after adjustment for potential confounding factors. However, no significant association was found for rectal cancer in women. In men, no significant decrease was observed in any colorectal cancer site. Further, additional analyses on the association of green tea consumption with colorectal cancer risk found no significant association in men or women. These findings suggest that coffee consumption may lower the risk of colon cancer among Japanese women. (c) 2007 Wiley-Liss, Inc.

The present study aimed to examine whether nutrient intakes predicted cognitive decline among elderly patients with diabetes mellitus. This study evaluated data from a 6-year prospective follow up of 237 elderly patients (aged ≥65 years) with diabetes mellitus, and the associations of baseline nutrient intakes with cognitive decline. Cognitive decline was defined as a ≥2-point decrease in the Mini-Mental State Examination (MMSE) score. Intakes of food and nutrients were assessed using a validated food frequency questionnaire, and were compared between patients with cognitive decline and intact cognition. Analysis of covariance and logistic regression analysis were used to compare the changes in the MMSE score during the follow up among intake tertile groups for each nutrient. Compared with men with intact cognition, the men with cognitive decline had lower baseline intakes of calcium, vitamin A, vitamin B 2 , pantothenate, soluble fiber, green vegetables and milk. However, no significant associations between cognitive decline and nutrient intakes were observed among women. After adjusting for age, body mass index, glycated hemoglobin levels, history of severe hypoglycemia, previous stroke and baseline MMSE score, we found that cognitive decline was significantly associated with low intakes of carotene, vitamin B 2 , pantothenate, calcium and green vegetables. Multiple logistic regression analysis showed that intakes of nutrients and green vegetables predicted cognitive decline after adjusting for age, body mass index, glycated hemoglobin levels, baseline MMSE score, and incident stroke during the follow up. These findings suggest that sufficient intakes of carotene, vitamin B 2 , pantothenate, calcium and vegetables could help prevent cognitive decline among elderly men with diabetes mellitus.

Depression is a common geriatric psychiatric disorder increasing with age among elderly people (≥ 75 years old), especially those with medical comorbidities. They have higher suicide rates than younger men, but these are paid less attention. Elderly men (n=141) who were newly admitted residents of the Veterans' Home in Tainan, Taiwan from 2004 to 2006 were recruited and screened for major depression. Specialist physicians obtained past histories of medical illnesses through chart reviews, interview, and health examinations. Fifty-nine of the 141 elderly people had major depression and participated in this study. Thirty-nine men in the group with vascular comorbidities (VC), and 20 in the group without (NVC) vascular comorbidities were compared. The VC group had more time-orientation impairment, greater psychomotor retardation, and diminished concentration/decision-making than did the NVC group. Psychomotor retardation and other cognitive function impairments (e.g., concentration and decision-making) are characteristic manifestations among patients with major depression and vascular comorbidity compared with those without vascular comorbidity.

To examine potential associations between socioeconomic factors and self-rated health among a national sample of Japanese men aged 50-59 years between 2005 and 2010, including the 2008 global financial crisis. Prospective cohort study. Randomly selected 2515 census areas from a total of 1.8 million census areas in Japan. This study utilised data from a national, longitudinal survey conducted by the Ministry of Health, Labour and Welfare. Starting in 2005, 16,738 Japanese men aged 50-59 years were recruited and sent a questionnaire each year. We analysed data for the 6-year period (2005-2010) from participants who had worked for over 20 years in the same industry (n=9727). We focused on worsening self-rated health status by occupation, education and employment contract. Working in the manufacturing industry was associated with worsening self-rated health scores when compared to those working in management (HR=1.19; 95% CI 1.04 to 1.37). A relationship between education level and worsening self-rated health was also identified as follows: junior high school (HR=1.49; 95% CI 1.31 to 1.69), high school (HR=1.29; 95% CI 1.17 to 1.42), and vocational college (HR=1.25; 95% CI 1.07 to 1.46), when compared with those holding university-level qualifications. Precarious employment (HR=1.17; 95% CI 1.00 to 1.37) was also associated with worsening self-rated health status in the current study. This study suggests that working in manufacturing for more than 20 years and having lower education levels may have a significant impact on the self-rated health of middle-aged Japanese men. This may reflect a progressive decline in Japanese working conditions following the global financial crisis and/or the impact of lower socioeconomic status.

Recent evidence has shown that type 2 diabetes mellitus (T2DM) in the elderly is a risk factor for cognitive dysfunction or dementia. However, the precise mechanisms have not yet been elucidated. In the current study, we attempted to elucidate the association of clinical indices and diabetic complications at baseline with cognitive declines after 6-year follow up in type 2 diabetic elderly. The subjects were 261 participants who were administered the Mini-Mental State Examination (MMSE) at baseline and after 6 years, at the end of the observation period. The cognitive decline was determined as a 5-point or greater decline in MMSE scores during the observation period. Logistic regression analysis to find the factors associated with cognitive decline, adjusted for age and sex, were carried out, and factors with P-values of less than 0.2 were included in four models of multiple logistic regression analysis. We found that the existence of diabetic nephropathy, higher systolic blood pressure and higher serum triglycerides (or lower high-density lipoprotein cholesterol) at baseline were significantly associated with cognitive declines after 6 years in Japanese elderly diabetics in all four models. The comorbidity of diabetic nephropathy, hypertension and hypertriglyceridemia at baseline were associated with more than 5-point declines in MMSE. Elucidation of the underlying mechanisms of this association is warranted. © 2012 Japan Geriatrics Society.

A key public health approach to promote independent living and avoid nursing home placement is ensuring that elders can obtain adequate informal support from family and friends, as well as formal support from community services. This study aims to describe the use of informal and formal support among community-dwelling Nikkei elders living alone, and explore perceived barriers hindering their use of such support. We conducted English and Japanese semi-structured, open-ended interviews in Chicagoland with a convenience sample of 34 Nikkei elders age 60+ who were functionally independent and living alone; 9 family/friends; and 10 local service providers. According to participants, for informal support, Nikkei elders relied mainly on: family for homemaking and health management; partners for emotional and emergency support; friends for emotional and transportation support; and neighbors for emergency assistance. Perceived barriers to informal support included elders' attitudinal impediments (feeling burdensome, reciprocating support, self-reliance), family-related interpersonal circumstances (poor communication, distance, intergenerational differences); and friendship/neighbor-related interpersonal situations (difficulty making friends, relocation, health decline/death). For formal support, Nikkei elders primarily used adult day care/cultural programs for socializing and learning and in-home care for personal/homemaking assistance and companionship. Barriers to formal support included attitudinal impediments (stoicism, privacy, frugality); perception of care (incompatibility with services, poor opinions of in-home care quality); and accessibility (geographical distance, lack of transportation). In summary, this study provides important preliminary insights for future community strategies that will target resources and training for support networks of Nikkei elders living alone to maximize their likelihood to age in place independently.

Nocturia is common among patients with type 2 diabetes mellitus, but limited evidence regarding the association between body mass index (BMI) and nocturia exists among such patients. The aim of the present study, therefore, was to evaluate the association between BMI and nocturia among Japanese patients with type 2 diabetes mellitus. Study participants were 809 Japanese patients with type 2 diabetes mellitus. Study participants were considered to have nocturia if they answered "two or more" to the question: "How many times do you typically wake up to urinate from sleeping at night until waking in the morning?" We used the following two outcomes: (i) moderate nocturia was defined as ≥2 voids per night; and (ii) severe nocturia was defined as ≥3 voids per night. Participants were categorized into four groups according to their BMI: (i) BMI <18.5; (ii) 18.5 ≤ BMI < 25; (iii) 25 ≤ BMI < 30; and (iv) BMI ≥30. Multiple logistical regression analysis for nocturia in relation to BMI was used, with the category of 18.5 ≤ BMI < 25 as the reference. Obesity (BMI ≥30) was independently positively associated with severe nocturia among elderly patients (age ≥65 years) with type 2 diabetes mellitus, but not among young and middle-aged patients: the adjusted OR was 2.96 (95% CI 1.10-7.83). BMI was not associated with moderate nocturia in all patients. In Japanese elderly patients with type 2 diabetes mellitus, obesity was independently positively associated with severe nocturia.

The objective of this study was to examine the association of plasma estradiol and testosterone with risk for dementia in elderly men. Within the population based Three-City study, including 3650 men age 65 years and older, a case-cohort design was set up after 4-years of follow-up. Baseline plasma levels of total 17-β estradiol (Total-E2), total testosterone (total-T) and bioavailable testosterone (bio-T) were measured for all cases of incident dementia (n=105) and for a random sample of the cohort (n=413). Cox regression models were used to estimate multivariate steroid sex hormone-associated hazard ratios (HR) and 95% confidence intervals of dementia. There was a reverse J-shaped relationship between total-T and risk for dementia (P=.007). Compared with the median tertile, the HRs associated with total-T in the lower and upper tertile were increased (HR, 2.33; P=.026; HR, 1.9, P=.126; respectively). Low bio-T was associated with a greater risk for dementia (HR for one standard deviation of decreasing log(bio-T), 1.29; 95% confidence interval, 1.03-1.62). An interaction was found between bio-T and age (P<.0001), and bio-T and education (P=.044). Risk for dementia associated with low bio-T was greater in older men (80 years or older) than in younger men (younger than 80 years; HR, 3.11; P=.011 vs. HR, 1.07, P=.715, respectively) and in men with high level of education compared with those with low level of education (HR, 2.32; P=.0002 vs. HR, 0.95; P=.790, respectively). No significant association was found between Total-E2 and dementia. Low levels of testosterone are associated with a risk for dementia in elderly men. The association between low bio-T and dementia may be more relevant to men 80 years or older and men with a high level of education. Copyright © 2014 The Alzheimer's Association.

There is increasing evidence suggesting that shift work involving night work may increase cancer risk. We examined the association between working rotating shifts and the risk of death from biliary tract cancer among Japanese men who participated in the Japan Collaborative Cohort Study. Of the 46,395 men recruited, 22,224 men aged 40-65 at baseline (1988-1990) who reported working full-time or were self-employed were included in the present analysis. The study subjects were followed through December 31, 2009. Information regarding occupation and lifestyle factors was collected using a self-administered questionnaire. Cox proportional hazard models were used to estimate the hazard ratio (HR) and 95 % confidence interval (CI) for the risk of death from biliary tract cancer in relation to shift work. During a mean 17-year follow-up, we observed 94 biliary tract cancer deaths, including 23 deaths from gallbladder cancer and 71 deaths from extrahepatic bile duct cancer. Overall, shift work was associated with a statistically non-significant increase in the risk of biliary tract cancer, with an HR of 1.50 (95 % CI: 0.81-2.77), among rotating shift workers. When the analysis was limited to extrahepatic bile duct cancer, a significant association appeared, with a multivariable-adjusted HR of 1.93 (95 % CI: 1.00-3.72) for rotating shift workers. Our data indicate that shift work may be associated with increased risk of death from extrahepatic bile duct cancer in this cohort of Japanese men. The association with gallbladder cancer remains unclear because of the small number of deaths.

Effect of aromatase inhibition on bone metabolism in elderly hypogonadal men.

Both estrogens and androgens play important roles in skeletal development and maintenance in men. The relative importance of estrogens and androgens in male bone metabolism, however, remains undefined. Anastrozole is an oral aromatase inhibitor that decreases estrogen production and increases androgen production in men. Currently, anastrozole is being investigated as a potential agent for the treatment of hypogonadism in aging men. Because anastrozole lowers estrogen levels and raises androgen levels, its effect on bone metabolism is difficult to predict. To assess the effects of anastrozole on bone turnover, we randomized 37 elderly (ages 62-74) mildly hypogonadal men (serum testosterone <350 ng/dl) to receive either anastrozole 1 mg daily (n=12), anastrozole 1 mg twice weekly (n=11), or daily placebo (n=14) for 12 weeks. Serum gonadal steroid levels, serum and urine biochemical markers of bone turnover, serum osteoprotegerin, and total body bone mineral density were measured at baseline and week 12. Mean serum levels of total and bioavailable testosterone increased substantially in both treated groups. Specifically, mean +/- SD bioavailable testosterone levels increased from 99+/-31 ng/dl to 207+/-65 ng/dl in the group receiving 1 mg of anastrozole daily and from 115+/-37 ng/dl to 178+/-55 ng/dl in the subjects receiving 1 mg of anastrozole twice weekly ( p <0.001 vs placebo for both groups). Serum estradiol levels decreased modestly in both treated groups (from 26+/-8 pg/ml to 17+/-6 pg/ml in the daily treatment group and from 27+/-8 pg/ml to 17+/-5 pg/ml in the twice-weekly treatment group, p <0.001 vs placebo for both groups). Despite these hormonal changes, no increases in biochemical markers of bone resorption were observed. Specifically, mean serum N-telopeptide and urinary deoxypyridinoline concentrations remained stable in both treated groups over the 12-week treatment period. Similarly, serum biochemical markers of bone formation (osteocalcin and amino

After retirement, elderly men and women allocate more time to housework activities, compared to working-age adults. Nonetheless, sleep constitutes the lengthiest time use activity among the elderly, but there has not been any study on the associations between time spent on housework activities, sleep duration and self-reported health among the older population. This study not only examined individual associations between self-reported health and both housework activities and sleep duration, but it also explored self-reported health by the interaction effect between housework activities and sleep duration separately for men and women. Pooled data from the Multinational Time Use Study (MTUS) on 15,333 men and 20,907 women from Germany, Italy, Spain, UK, France, the Netherlands and the US were analysed. Multiple binary logistic regression models were used to examine the associations between three broad categories of housework activities ((1) cooking, cleaning and shopping, (2) gardening and maintenance; (3) childcare) and health. We further investigated the extent to which total housework hours and sleep duration were associated with self-reported health for men and women separately. We found a positive association between time devoted to housework activities, total housework and health status among elderly men and women. Compared to those who spent 1 to 3 h on total productive housework, elderly people who spent >3 to 6 h/day had higher odds of reporting good health (OR = 1.25; 95% CI = 1.14-1.37 among men and OR = 1.10; 95% CI = 1.01-1.20 among women). Both short (<7 h) and long (>8 h) sleep duration were negatively associated with health for both genders. However, the interactive associations between total productive housework, sleep duration, and self-reported health varied among men and women. Among women, long hours of housework combined with either short or long sleep was negatively associated with health. Although time allocation to

ST segment depression (STDE) has been found to be associated with cardiovascular disease in the elderly. Studies of the relation of ambulatory STDE to cognitive function in elderly persons aged 80 years or above is lacking. Objective: To study the association between STDE and cognition. Design and participants: A cross-sectional cohort study of 88 81-year-old men from the population study “Men born in 1914” investigated in an outpatient research clinic. Measurements included ambulatory 24-hour electrocardiogram (ECG) monitoring and a cognitive test battery of six tests. Proportion of lower cognitive function was calculated for each test in relation to STDE during the day and at night-time. Results: Fifty-eight percent of the men had STDE and a higher proportion with low visuospatial cognitive function was found among those with STDE compared to the others (84% vs 59%; p = 0.014). A significant trend was noted for subjects without STDE compared to STDE night-time less than 60 minutes and night-time more than 60 minutes for spatial and verbal cognitive functions (p = 0.022). No trends were noted for STDE daytime. Maximal STDE during night showed similar association to spatial function (Benton Visual Retention test, r = −0.26; p = 0.028). Even when seven subjects with a history of stroke were excluded, the occurrence of STDE was associated to lower visuospatial cognitive function compared to those without STDE (87% vs 57%; p = 0.004). Conclusion: ST segment depression on ECG is common among elderly men and might be a vascular risk factor for cognitive deterioration. PMID:20360898

It has been hypothesized that working beyond retirement age may have a protective effect on various aspects of well-being in the elderly. This paper aims to examine the relationship between employment status of elderly Singaporeans and indicators of well-being. As part of the Well-being of the Singapore Elderly study, data relating to sociodemographics, social networks, medical history, physical activity, cognitive function, and disability were collected from 2534 participants aged 60 years and older. Participants included full-time workers (n = 483), part-time workers (n = 205), the unemployed (n = 32), homemakers (n = 808), and retirees (n = 1006). The data were analyzed by multiple logistic regression. Likelihood of being employed decreased with age, and employment was higher among men. Paid workers had significantly higher levels of physical activity, more extensive social networks, better cognitive function, less disability, and lower risk of dementia than retirees and homemakers. Paid workers had significantly lower chronic disease burden than retirees and rated their health to be better than retirees and the unemployed. These findings show that meaningful employment is associated with better psychological and physiological well-being among the elderly, highlighting the importance of studying likely protective effects of employment and creating employment opportunities for elderly Singaporeans. © 2016 The Authors.

I examine the attitudinal ambivalence created by conflicting social expectations regarding parent-child devotion, filial obligation and family membership, and gender norms in a national population of Japanese adults. I ask: in a context of rapidly changing family and elder care norms, how do different beliefs and attitudes overlap and conflict and how are they related to elder care preferences? I analyze data from the 2006 Japanese General Social Survey and use Latent Class Analysis to identify latent groups in the population defined by their beliefs and examine the relationship between class membership and elder care preferences. I found variation in the population with respect to the measured beliefs as well as a relationship between patterns of beliefs and choice of elder caregiver. I found conflicting expectations regarding elder care responsibility in one latent class and this class also expressed elder care preferences that conflict with at least some of their strongly held beliefs.

In this study, we examined the relationship between sarcopenic obesity (SO) and nutrition status, according to sex in Korean adults who were 60 years or older. Body composition was categorized as SO, sarcopenic nonobesity, nonsarcopenic obesity, and nonsarcopenic nonobesity. Obesity was defined by body mass index. Sarcopenia was defined as an appendicular skeletal muscle mass divided by weight (Wt) of less than 1 SD below the sex-specific mean for young adults. Subjects included 1433 subjects (658 men and 775 women) who were 60 years or older and who participated in the fifth Korea National Health and Nutritional Examination Survey 2010. Sarcopenic obesity was more prevalent in women (31.3%) than in men (19.6%). Individuals with SO had significantly higher fasting insulin, homeostasis model assessment of insulin resistance (male: 3.2 ± 1.4, female: 3.4 ± 2.1), and triglycerides (male: 167.3 ± 90.6 mg/dL, female: 160.7 ± 85.0 mg/dL). High-density lipoprotein was under the normal criteria (50 mg/dL) in women. Intake of nutrients associated with muscle loss (protein, vitamin D, calcium, and vitamin C) was significantly different among the male but not the female groups. Although protein intake was normal, calcium and vitamin D intakes were insufficient in all groups. In conclusion, body composition changes were related to nutrient intakes in elderly (60 years or older) men but not elderly women. Women had a higher prevalence of SO than did men, suggesting that early nutritional intervention in elderly women may help them address age-associated body composition changes.

Aim: There are few data regarding associations between sleep duration and subclinical atherosclerosis in Japan. The aim of this study was to evaluate associations of self-reported sleep duration with calcification in the coronary arteries (CAC) and carotid intima media thickness (IMT) in Japanese men. Methods: This was a cross-sectional survey of 1093 randomly selected men from Kusatsu City, Japan. Average sleep duration on weekdays was estimated through questionnaire; CAC by computed tomography; and carotid IMT by ultrasonography. Results: The prevalence of CAC was 50.0% for participants with sleep duration < 5.5 h, 43.9% with 5.5–6.4 h, 50.0% with 6.5–7.4 h, 49.3% with 7.5–8.4 h, and 62.5% with ≥ 8.5 h. In univariate analysis, participants with sleep duration ≥ 8.5 h had significantly higher prevalence of CAC than those with 6.5–7.4 h (p = 0.043). After adjustment for age and other risk factors, however, the association was not significant (p = 0.776). The average IMT was 0.85 mm for participants with sleep duration < 5.5 h, 0.83 mm with 5.5–6.4 h, 0.85 mm with 6.5–7.4 h, 0.88 mm with 7.5–8.4 h, and 0.90 mm with ≥ 8.5 h. None of the differences in IMT observed in crude or multivariable-adjusted analyses was significant (all p > 0.1). Conclusion: Self-reported sleep duration was not associated with increased CAC or carotid IMT in a general population of Japanese men. PMID:28747590

Research has demonstrated a relationship between social support, cognitive function, and depression among older adults, yet fewer studies have explored this association with Japanese American elders. This study aims to examine depression and describe its relationship with social support, cognitive function, and socioeconomic condition among Japanese American elders. A cross-sectional study of 205 Japanese American elders was conducted in Honolulu and Los Angeles County. A hierarchical regression model was used with depression as a dependent variable and with independent variables such as social support, cognitive function, and socioeconomic status. The study found that social support and cognitive function were significantly associated with depression for Japanese American elders. Also age and education were significantly associated with depression. Based on the findings, the study indicates the importance of developing preventive strategies to reduce the depression issue using culturally tailored programs to the study population.

To assess whether nutritional status based on the Nutrition Screening Initiative Checklist is useful for predicting functional capacity decline in community-dwelling Japanese elderly. This two-year observational cohort study included 536 community-dwelling Japanese (65 years and older at baseline) who were independent in both activities and instrumental activities of daily living. Demographic attributes, chronic illness, lifestyle-related habits, nutritional status, functional capacity, and anthropometric measurements were assessed, with decline in functional capacity used as the outcome measure. Subjects were classified into three groups as follows based on the Nutrition Screening Initiative Checklist: low (59.5%), moderate (23.7%), and high (16.8%) nutritional risk. Significant differences were found between nutritional status and the following four baseline variables: age, hypertension, cerebrovascular diseases, and current smoking. However, no significant differences were evident between nutritional status and sex, body mass index, diabetes, drinking habit, or exercise habit. Logistic regression analysis adjusted for age, sex, body mass index, hypertension, cerebrovascular diseases and smoking habit showed that the high nutritional risk group was significantly associated with a decline in both activities of daily living (odds ratio: 4.96; 95% confidence interval (CI): 1.59-15.50) and instrumental activities of daily living (OR: 2.58; 95% CI: 1.31-5.06) compared with the low nutritional risk group. Poor nutritional status based on the Nutrition Screening Initiative Checklist was associated with a decline in functional capacity over a 2-year period in community-dwelling Japanese elderly. These results suggest that the Nutrition Screening Initiative Checklist is a suitable tool for predicting functional capacity decline in community-dwelling elderly.

A retrospective study was performed to evaluate the outcome of alendronate treatment for 7 years among Japanese men with osteoporosis or osteopenia and clinical risk factors for fractures. Thirty-five Japanese men with osteoporosis or osteopenia and clinical risk factors for fractures (mean age at baseline 58.2 years) who had been treated with alendronate for over 7 years in our outpatient clinic were analyzed. The lumbar spine or total hip bone mineral density (BMD) was measured using dual energy X-ray absorptiometry; the urinary levels of cross-linked N-terminal telopeptides of type I collagen (NTX) and the serum levels of alkaline phosphatase (ALP) were monitored; the incidence of fractures during the 7-year treatment period was then assessed. The urinary NTX and serum ALP levels decreased (-46.1% at 3 months and -21.1% at 7 years, respectively) and the lumbar spine and total hip BMD increased (+14.2 and +10.1% at 7 years, respectively), compared with the baseline values. Four patients (11.4%) experienced vertebral fractures, and one patient (2.9%) experienced a nonvertebral fracture. No serious adverse events were observed, including osteonecrosis of the jaw or atypical femoral fractures. These results suggested that alendronate suppressed bone turnover and increased the lumbar spine and total hip BMD from the baseline values over the course of the 7-year treatment period without causing any severe adverse events in Japanese men with osteoporosis or osteopenia and clinical risk factors for fractures.

There is a high incidence of hip fractures in patients with Parkinson disease (PD). Bone mineral density (BMD) is decreased in patients with PD, correlating with the immobilization-induced bone resorption and hypovitaminosis D with compensatory hyperparathyroidism. To evaluate the effectiveness of risedronate, an inhibitor of bone resorption, on osteoporosis and the risk of hip fractures in elderly men with PD. This was a 2-year, randomized, double-blind, placebo-controlled trial. In a prospective study of patients with PD, 121 patients received a daily dose of 2.5 mg risedronate and vitamin D2 1,000 IU for 2 years, and the remaining 121 received placebo and vitamin D2 1,000 IU. Incidence of hip fractures was compared between the two groups. Nine patients sustained hip fractures in the placebo group, and three hip fractures occurred in the risedronate group. The relative risk of a hip fracture in the risedronate group vs the placebo group was 0.33 (95% CI, 0.09 to 1.20). BMD increased by 2.2% in the risedronate group and decreased by 2.9% in the placebo group (p < 0.0001). Urinary deoxypyridinoline, a bone resorption marker, decreased by 46.7% in the risedronate group and by 33.0% in the placebo group. Treatment with risedronate and vitamin D2 increases bone mineral density in elderly men with Parkinson disease and reduces the risk of hip fractures.

Aging is known to be associated with increased risk of lipid disorders related to the development of type 2 diabetes. Recent evidence revealed that change of lipid molecule species in blood is associated with the risk of type 2 diabetes. However, changes in lipid molecular species induced by aging are still unknown. We assessed the effects of age on the serum levels of lipid molecular species as determined by lipidomics analysis. Serum samples were collected from ten elderly men (71.7 ± 0.5 years old) and women (70.2 ± 1.0 years old), ten young men (23.9 ± 0.4 years old), and women (23.9 ± 0.7 years old). Serum levels of lipid molecular species were determined by liquid chromatography mass spectrometry-based lipidomics analysis. Our mass spectrometry analysis revealed increases in the levels of multiple triacylglycerol molecular species in the serum of elderly men and women. Moreover, serum levels of total ester-linked phosphatidylcholine (PC) and phosphatidylethanolamine (PE) were increased by aging. In contrast, serum levels of specific ether-linked PC and PE molecular species were lower in elderly individuals than in young individuals. Our finding indicates that specific lipid molecular species, such as ether- and ester- linked phospholipids, may be selectively altered by aging.

We recently reported that Japanese had higher liver fat at a lower level of BMI compared with non-Hispanic whites (NHW). We hypothesize that ethnic difference in fat storage capacity contributes to this ethnic difference in liver fat. To examine this, we assessed liver fat among 244 Japanese-American aged 40-49, using regional computed-tomography images, along with metabolic variables. Despite the similar BMI between Japanese-Americans and NHW men, Japanese-Americans had more liver fat (liver to spleen attenuation ratio: 1.03 ± 0.22 for Japanese-Americans, and 1.07 ± 0.15 for NHW men; p < 0.05) and tended to have a greater disposition for fatty liver with an increase in BMI than NHW, indicating a clear difference between the two groups. In addition, liver fat is less in Japanese-Americans compared with Japanese men (1.03 ± 0.22 vs. 1.01 ± 0.16; p < 0.05), despite of a much higher BMI. These ethnic differences support the hypothesis that higher fat storage capacity indeed seems to be associated with less liver fat. In all the groups, liver fat content strongly correlated with triglycerides, homeostasis model assessment-insulin resistance, and C-reactive protein (CRP). Nevertheless, these metabolic variables were worse in Japanese-Americans, despite of less liver fat, compared with Japanese. Moreover, CRP levels were least among Japanese with highest liver fat, and highest among NHW men with least liver fat, despite of a strong positive association between CRP and fatty liver within each population. Fat content in the liver is intermediate for Japanese-Americans compared with Japanese and NHW men, which supports the hypothesis of less fat storage capacity among Japanese, closely linked to ethnic difference in predisposition to fatty liver. © 2011 Asian Oceanian Association for the Study of Obesity.

Decreased circulating tryptophan (Trp) levels are frequently observed in elderly patients with neurodegenerative disease including Alzheimer's disease. Trp may serve as a potential biomarker for monitoring disease risk in elderly people. We aimed to investigate the association between low plasma Trp levels and olfactory function, which is known to predict age-related diseases including dementia in elderly people. A total of 144 healthy elderly Japanese community (≥ 65 years old) dwellers from the Health, Aging and Nutritional Improvement study (HANI study) were the subjects of our analysis. Low Trp levels were classified using the lower limit values of the reference interval according to a previous report. Olfactory function was assessed using a card-type test called Open Essence, which includes 12 odour items that are familiar to Japanese people. The elderly subjects with low circulating Trp levels were compared to a control group with normal plasma Trp levels. We conducted the analyses using 144 people aged 65 years or older (mean age 73.7 ± 5.5 years; 36.1% men). The subjects showed normal serum albumin levels (4.4 ± 0.2 g/dL) and no daily living disabilities. Low plasma Trp levels (low Trp group) were found in 11.1% of the study population. The low Trp group showed a significantly lower correct-answer rate for the items india ink, perfume, curry and sweaty smelling socks than control group (P < 0.05). There was also a significant association between low Trp levels and low olfactory ability, after adjusting for age and sex. Lower plasma Trp levels were associated with a decrease in olfactory function in functionally competent older individuals. Because olfactory dysfunction predicts age-related diseases, low plasma Trp levels may represent a clinical sign of disease risk in elderly people.

Objective: Participation in social activities is associated with physical and psychological health in the community-dwelling elderly population. We examined the two factors of social relations and community health resources, associated with higher self-rated health levels in the community-dwelling elderly. Methods: A total of 145 community-dwelling elderly people ≥ 65 years old from two neighborhood associations in Nagasaki City were recruited for this study, representing 85% of the officially registered ≥ 65-year-old population in the target area. Face-to-face interviews using a structured questionnaire were conducted by trained interviewers in August 2009, with questions related to sociodemographic characteristics, social relationships, and self-rated health (SRH). Community health resources (type and walking distance from home) were evaluated by one of the authors as a community assessment. Results: Seventy-eight community-dwelling elderly people (25 men and 53 women) participated in the study. Elderly people who reported going out every day were more likely to show higher SRH scores (excellent/good) than those going out less often (OR: 3.7; 95% confidence interval [CI]: 1.0, 14.2; P = 0.056). The numbers of interactions with friends in higher and lower SRH groups were 6.5 ± 8.4 (mean ± standard deviation) and 2.4 ± 1.1 ( P = 0.01, Mann-Whitney U test), respectively. The numbers of relatives talking on the phone in higher and lower SRH groups were 2.9 ± 1.3 and 2.2 ± 1.2 ( P = 0.031, Mann-Whitney U test), respectively. Meeting scores with friends in higher and lower SRH groups were 7.8 ± 5.8 and 4.5 ± 3.6 ( P = 0.068), respectively. The scores of community health resources among higher and lower SRH groups were 21.2 ± 1.5 and 20.9 ± 1.4 ( P = 0.547), respectively. The scores of community association/activities in higher and lower SRH groups were 3.9 ± 1.0 and 3.6 ± 0.9 ( P = 0.227), respectively. Conclusion: This study indicated the importance

Impaired endothelial function is observed with aging and in those with low cardiorespiratory fitness (V̇o 2peak ). Improvements in endothelial function with exercise training are somewhat dependent on the intensity of exercise. While the acute stimulus for this improvement is not completely understood, it may, in part, be due to the flow-mediated dilation (FMD) response to acute exercise. We examined the hypothesis that exercise intensity alters the brachial (systemic) FMD response in elderly men and is modulated by V̇o 2peak Forty-seven elderly men were stratified into lower (V̇o 2peak = 24.3 ± 2.9 ml·kg -1 ·min -1 ; n = 27) and higher fit groups (V̇o 2peak = 35.4 ± 5.5 ml·kg -1 ·min -1 ; n = 20) after a test of cycling peak power output (PPO). In randomized order, participants undertook moderate-intensity continuous exercise (MICE; 40% PPO) or high-intensity interval cycling exercise (HIIE; 70% PPO) or no-exercise control. Brachial FMD was assessed at rest and 10 and 60 min after exercise. FMD increased after MICE in both groups {increase of 0.86% [95% confidence interval (CI), 0.17-1.56], P = 0.01} and normalized after 60 min. In the lower fit group, FMD was reduced after HIIE [reduction of 0.85% (95% CI, 0.12-1.58), P = 0.02] and remained decreased at 60 min. In the higher fit group, FMD was unchanged immediately after HIIE and increased after 60 min [increase of 1.52% (95% CI, 0.41-2.62), P < 0.01, which was correlated with V̇o 2peak , r = 0.41; P < 0.01]. In the no-exercise control, FMD was reduced in both groups after 60 min ( P = 0.05). Exercise intensity alters the acute FMD response in elderly men and V̇o 2peak modulates the FMD response following HIIE but not MICE. The sustained decrease in FMD in the lower fit group following HIIE may represent a signal for vascular adaptation or endothelial fatigue. NEW & NOTEWORTHY This study is the first to show that moderate-intensity continuous cycling exercise increased flow-mediated dilation (FMD

Background Common variants on human chromosome 8q24, rs1447295 (C/A) and rs6983267 (T/G), have been recently linked to the prevalence of prostate cancer in European and American populations. Here, we evaluated whether the single-nucleotide polymorphisms rs1447295 and rs6983267 were associated with the risk of sporadic prostate cancer as well as latent prostate cancer in a native Japanese population. Results We analyzed genomic DNA samples from 391 sporadic prostate cancer patients, 323 controls who had died from causes unrelated to cancer and 112 Japanese men who were diagnosed as having latent prostate cancer based on autopsy results. The polymorphisms were determined by allelic discrimination using a fluorescent-based TaqMan assay. The A allele of rs1447295 was significantly associated with the risk of sporadic prostate cancer (p = 0.04; age-adjusted OR, 1.34), while the G allele of rs6983267 showed a trend towards being a high-risk allele (p = 0.06; age-adjusted OR, 1.27). No significant difference between these two polymorphisms and the risk of latent prostate cancer was observed in the present Japanese population. Conclusion Known variants on human chromosome 8q24 may be risk factors for sporadic prostate cancer in native Japanese men. PMID:19602258

Background Previous studies have shown that a diet with a high-glycemic index is associated with good sleep quality. Therefore, we investigated the association of sleep quality with the intake of 3 common starchy foods with different glycemic indexes–rice, bread, and noodles–as well as the dietary glycemic index in a Japanese population. Methods The participants were 1,848 men and women between 20 and 60 years of age. Rice, bread, and noodle consumption was evaluated using a self-administered diet history questionnaire. Sleep quality was evaluated by using the Japanese version of the Pittsburgh Sleep Quality Index, and a global score >5.5 was considered to indicate poor sleep. Results Multivariate-adjusted odds ratios (95% confidence intervals) for poor sleep across the quintiles of rice consumption were 1.00 (reference), 0.68 (0.49–0.93), 0.61 (0.43–0.85), 0.59 (0.42–0.85), and 0.54 (0.37–0.81) (p for trend = 0.015); those for the quintiles of noodle consumption were 1.00 (reference), 1.25 (0.90–1.74), 1.05 (0.75–1.47), 1.31 (0.94–1.82), and 1.82 (1.31–2.51) (p for trend = 0.002). Bread intake was not associated with sleep quality. A higher dietary glycemic index was significantly associated with a lower risk of poor sleep (p for trend = 0.020). Conclusion A high dietary glycemic index and high rice consumption are significantly associated with good sleep in Japanese men and women, whereas bread intake is not associated with sleep quality and noodle consumption is associated with poor sleep. The different associations of these starchy foods with sleep quality might be attributable to the different glycemic index of each food. PMID:25127476

Sexuality in the elderly is still a social taboo. A commitment by medical practices to address the topic of sexuality in later life is essential, given that the sexual health is part of the quality of life. Identification of barriers and discourse of effects in the physician's behavior when dealing with the sexuality of older people. Review and discussion of interdisciplinary literature and social discourse. Compilation of expert opinions. Although the introduction of phosphodiesterase 5 inhibitors led to a removal of taboos concerning erectile dysfunction, the sexuality of older men became narrowed to physiological aspects. The elderly still complain that consultations concerning their sexuality receives too little attention in medical practice. Problems are boundaries of shame and disregard of the sexuality of elderly. Sexuality in old age will have to become more prominent in medical practices, due to demographic changes and changing self-images of the elderly. The social role of physicians enables straightforward discussions about sexuality. Taking a sexual history and choosing an active approach proved to be practicable to discuss sexual problems with older people.

In this study of Japanese men and women, we determine reference values for sarcopenia and test the hypothesis that sarcopenia is associated with risk factors for cardiovascular disease, independent of waist circumference. A total of 1,488 Japanese men and women aged 18-85 years participated in this study. Appendicular muscle mass (AMM) was measured by dual-energy X-ray absorptiometry. Reference values for classes 1 and 2 sarcopenia (skeletal muscle index: AMM/height2, kg m-2) in each sex were defined as values one and two standard deviations below the sex-specific means of reference values obtained in this study from young adults aged 18-40 years. The reference values for class 1 and class 2 sarcopenia were 7.77 and 6.87 kg m-2 in men and 6.12 and 5.46 kg m-2 in women. In subjects both with class 1 and class 2 sarcopenia, body mass index and % body fat were significantly lower than in normal subjects. Despite whole-blood glycohaemoglobin A1c in men with class 1 sarcopenia was significantly higher than in normal subjects, and brachial-ankle pulse wave velocity in women both with class 1 and class 2 sarcopenia were significantly higher than in normal subjects, using one-way ANCOVA with adjustment for the covariate of waist circumference. Although sarcopenia is associated with thin body mass, it is associated with more glycation of serum proteins in men and with greater arterial stiffness in women, independent of waist circumference.

The association between the oxidative status and metabolic syndrome (MetS) should be studied in various populations with various oxidative stress-related markers. The aim of this cross-sectional study was to investigate the association between oxidative status, as assessed by the reactive oxygen metabolites (d-ROMs) test, and MetS in asymptomatic Japanese men, in relation to age. The serum d-ROMs levels were measured in cardiovascular disease-free, non-smoking, non-medicated males (n = 140), who were divided into groups as follows: Group 1, < 60 years (n = 75, mean age 46 ± 9 [SD] years), and Group 2, ≥ 60 years (n = 65, mean 68 ± 6 years). The MetS was determined by the NCEP-ATP recommendations with minor modifications for a Japanese population. There was no significant difference in the d-ROMs levels between the subjects with and without MetS in Group 2 (≥ 60 years), but the subjects with MetS (n = 38, 324 ± 59 U. Curr.) exhibited significantly higher d-ROMs levels than those without MetS (n = 37, 290 ± 49 U. Curr., P < 0.01) in Group 1 (< 60 years). These differences did not change even after adjustments for basic confounders. These results suggest that oxidative status, as assessed by the d-ROMs, can be enhanced among asymptomatic younger, but not older, Japanese males with MetS. Further studies are required to establish the observed associations. Oxidative stress; Reactive oxygen species; D-ROMs; Obesity; Metabolic syndrome.

To test the hypothesis that elderly persons who feel ikigai (a sense of life worth living) have a lower risk of incident functional disability than those who do not. Recent studies have suggested that ikigai impacts on mortality. However, its impact upon disability is unknown. The aim of the present study was to investigate the association between ikigai and incident functional disability among elderly persons. We conducted a prospective cohort study of 830 Japanese elderly persons aged ≥70 years as a comprehensive geriatric assessment in 2003. Information on ikigai was collected by self-reported questionnaire. Data on functional disability were retrieved from the public Long-term Care Insurance database in which participants were followed up for 11 years. Hazard ratios (HRs) and 95% confidence intervals (CIs) for incidence of functional disability were calculated for three groups delineated according to the presence of ikigai (“no”, “uncertain” or “yes”) using the Cox proportional hazards regression model. The 11-year incidence of functional disability was 53.3% (442 cases). As compared with the “no” group, the multiple-adjusted HR (95% CI) of incident functional disability was 0.61 (0.36–1.02) for the “uncertain” group and 0.50 (0.30–0.84) for the “yes” group. A stronger degree of ikigai is significantly associated with a lower risk of incident functional disability. Copyright © 2017 Elsevier Inc. All rights reserved.

Aging leads to low functional capacity and this can be reversed by safe and adequate exercise prescription. The aim of this study was to identify the anaerobic threshold (AT) obtained from the V-slope method as well as visual inspection of oxyhemoglobin ( O2Hb) and deoxyhemoglobin (HHb) curves and compare findings with the heteroscedastic (HS) method applied to carbon dioxide production ( CO2), heart rate (HR), and HHb data in healthy elderly men. A secondary aim was to assess the degree of agreement between methods for AT determination. Fourteen healthy men (61.4±6.3 years) underwent cardiopulmonary exercise testing (CPX) on a cycle ergometer until physical exhaustion. Biological signals collected during CPX included: ventilatory and metabolic variables; spectroscopy quasi-infrared rays - NIRS; and HR through a cardio-frequency meter. We observed temporal equivalence and similar values of power (W), absolute oxygen consumption (O2 - mL/min), relative O2 ( mL.Kg - 1.min -1), and HR at AT by the detection methods performed. In addition, by the Bland-Altman plot, HR confirmed good agreement between the methods with biases between -1.3 and 3.5 beats per minute. (i) all detection methods were sensitive in identifying AT, including the HS applied to HR and (ii) the methods showed a good correlation in the identification of AT. Thus, these results support HR as valid and readily available parameter in determining AT in healthy elderly men.

In the current recommendations for energy intake of different countries as well as in the international WHO recommendations for energy intake it is assumed that the elderly are less physically active than young adults. Therefore, the aim of the present study was to compare physical activity patterns and physical activity level (PAL) of young and elderly subjects. In 178 female (age 67.8+/-5.7 y, BMI 26.4+/-3.7 kg/m(2)) and 107 male (age 66.9+/-5.1 y, BMI 26.3+/-3.1 kg/m(2)) participants of the longitudinal study on nutrition and health status in an aging population of Giessen, Germany as well as in a young age group consisting of 154 women (age 24.8+/-3.0 y, BMI 21.0+/-2.2 kg/m(2)) and 68 men (age 26.8+/-3.4 y, BMI 23.3+/-2.4 kg/m(2)) different activities like occupational work, housework, gardening, walking and sports were assessed by a questionnaire. Energy expenditure of the different activities was calculated using multipliers for resting metabolic rate (RMR) according to the WHO. The same multipliers were used for young and elderly subjects. RMR was measured by indirect calorimetry after an overnight fast. PAL of the subjects was calculated as total energy expenditure divided by RMR. Young adults did more occupational work and performed more sports than elderly subjects. In contrast elderly women did more housework in comparison to young women, and elderly men walked more than young men. Both elderly women and men did more gardening than young women and men. In elderly women, PAL was significantly higher in comparison to young women, whereas PAL of young and elderly men did not differ significantly. The results indicate that despite different activity patterns, the young-old do not necessarily show a lower PAL than young subjects.

To comparatively investigate whether dynapenia and sarcopenia, as defined by the Asian Working Group for Sarcopenia (AWGS), are associated with fear of falling in elderly patients with diabetes. The subjects were outpatients with diabetes who were at least 65 years of age when they visited our hospital. Sarcopenia was evaluated based on the AWGS definition. The cutoff values for the appendicular skeletal mass index (multi-frequency bioelectrical impedance method), grip strength, and walking speed were, respectively, 7.0 kg/m 2 for men and 5.7 kg/m 2 for women, 26 kg for men and 18 kg for women, and ≤0.8 m/s for both men and women. Those with grip strength of less than or equal to the cutoff value were considered to have dynapenia. Fear of falling was assessed by a self-administered questionnaire survey with the Fall Efficacy Scale (FES) Japanese version. A multiple regression analysis was conducted using the FES score as a dependent variable and dynapenia or sarcopenia and moderators as explanatory variables. A total of 202 patients (male, n=127; female, n=75) were analyzed in this study. The FES scores of the patients with and without sarcopenia did not differ to a statistically significant extent in either male or female patients. The multiple regression analysis revealed a statistically significant association between dynapenia and the FES score in men (P=0.028). In elderly outpatients with diabetes, no association was found between sarcopenia and the fear of falling in either men or women. In contrast, a statistically significant association was found between dynapenia and fear of falling in men. This suggests the importance paying attention to the fear of falling when examining elderly male diabetes patients with dynapenia.

Sarcopenia is a major determinant of frailty, disability and mortality in the elderly. Whether low-grade inflammation, insulin resistance and vitamin D are independently associated with sarcopenia remains unclear. In our study, sarcopenia was defined as an appendicular skeletal muscle mass divided by height squared (ASM/Ht 2 ) that was <2 SD below the normal means for young adults. Insulin resistance was estimated using the homeostasis model assessment of insulin resistance (HOMA-IR) index [(insulin (IU/mL) × fasting glucose (mg/dL)/18)/22.5]. Data of white blood cell counts and serum 25-hydroxyvitamin D (25-(OH)D) levels were collected in the second and third year (2008-2009) of Fourth Korean National Health and Nutrition Examination Survey (KNHANES IV). The results showed that the prevalence of sarcopenia in Korean elderly men aged more than 65 years was 11.2%. ASM/Ht 2 were positively associated with vitamin D levels, but negatively associated with white blood cell counts and HOMA-IR by multiple regression analysis. After adjustment for covariables, sarcopenia was associated with the highest quartile of WBC counts (OR = 2.93, 95% CI = 1.21-7.14) and the highest quartile of serum vitamin D levels (OR = 0.38, 95% CI = 0.15-0.95). In conclusion, the study findings suggest that higher WBC counts and lower vitamin D levels are independently associated with the presence of sarcopenia in community-dwelling elderly men. They also provide a basis for further studies of the complex immune-endocrine network in sarcopenia.

Japan has experienced pronounced population aging, and now has the highest proportion of elderly adults in the world. Yet few projections of Japan's future demography go beyond estimating population by age and sex to forecast the complex evolution of the health and functioning of the future elderly. This study estimates a new state-transition microsimulation model - the Japanese Future Elderly Model (FEM) - for Japan. We use the model to forecast disability and health for Japan's future elderly. Our simulation suggests that by 2040, over 27 percent of Japan's elderly will exhibit 3 or more limitations in IADLs and social functioning; almost one in 4 will experience difficulties with 3 or more ADLs; and approximately one in 5 will suffer limitations in cognitive or intellectual functioning. Since the majority of the increase in disability arises from the aging of the Japanese population, prevention efforts that reduce age-specific morbidity can help reduce the burden of disability but may have only a limited impact on reducing the overall prevalence of disability among Japanese elderly. While both age and morbidity contribute to a predicted increase in disability burden among elderly Japanese in the future, our simulation results suggest that the impact of population aging exceeds the effect of age-specific morbidity on increasing disability in Japan's future.

The relationship of the levels of cariogenic bacterial species with periodontal status and decayed root surfaces was investigated in elderly Japanese subjects. Three hundred and sixty-eight individuals (each 75 years old) were examined for periodontal status (pocket depth, attachment loss), root surface caries and salivary levels of mutans streptococci (MS) and lactobacilli (LB). Values >4 mm of attachment loss (rAL4) and for average attachment loss (aAL) of sites measured were significantly higher in subjects with LB than those without. Multiple regression analysis also showed a correlation between aAL and rAL4 values with the presence of LB (aAL p = 0.003; rAL4 p = 0.002). Further, multiple regression analysis of interacting factors regarding decayed root surfaces showed that LB carriers had a greater incidence of decayed root surface caries (p = 0.003), while MS and LB levels were correlated to the number of decayed root surfaces (LB p = 0.010; MS p = 0.026). Our results indicate that considerable attachment loss elevates the possibility of having LB, thus increasing the risk of root surface caries. It was also found that LB and MS measurements may be useful indicators of decayed root surfaces in elderly individuals with attachment loss.

It is important to promote self-efficacy for exercise for developing exercise habit. The purpose of this study was to investigate factors influenced by self-efficacy for exercise among community-dwelling elderly men in urban areas. The subjects were 69 elderly men (mean age of 74.2±2.0 SD) who had given approval for participation in the study. We examined the following factors: family situation, history of falls, frequency of going out, stage model of a change, self-efficacy for exercise, fall efficacy scale (FES), geriatric depression scale (GDS), subjective health, functional ability and motor function (5 m walking time, chair stand test-5times). Analysis of variance was used to assess a stage model of a change differences in self-efficacy for exercise and other measures. Correlation analysis and multiple regression analysis were performed to determine the relationships between self-efficacy for exercise and other measures. We found that self-efficacy of exercise, FES, GDS (p<0.01) and CST (p<0.05) vary depending on the stage model of change. Self-efficacy for exercise was found to correlate with psychological factors and functional ability (|r|=0.47-0.67). Multiple regression analysis revealed that the independent factors related to self-efficacy for exercise were FES and GDS. FES and GDS were found to be significant and independent predictors of self-efficacy for exercise in community-dwelling elderly men in urban areas. We should consider not only the approach based on behavioral science but also mental support for depression and fear of falling to promote exercise self-efficacy.

This study examined the factors that allow elderly individuals to stay at home continuously by considering the roles of the family caregiver, the use of services and characteristics of the elderly individual. We analyzed 432 elderly individuals living at home with family. The outcome was that participants remained at home continuously over a 24-month period. The participants were stratified into two care-needs levels, and then multiple logistic regression analyses were carried out to examine relationships between staying at home and the Japanese version of the Zarit Burden Interview (J-ZBI), public Long-term Care Insurance (LTCI) service use, family caregivers' characteristics and elderly peoples' characteristics. Low scores on the J-ZBI were related to outcome in both care-needs subgroups (low care-needs subgroup: OR 2.11; 95% CI 1.31-3.43, high care-needs subgroup: OR 5.03; 95% CI 1.04-31.1). Regarding LTCI services, the use of home-visit nursing (HN) service was related to staying at home continuously in the high care-needs group (OR 37.39; 95% CI 3.31-879.1). Alleviation of caregiver' burden was essential for continuous stay at home of elderly people regardless of care-needs levels. Also, the HN service was founded as the relevant LTCI service factor for staying at home continuously. The HN service use might affect the outcome when we consider the causal relationship. Therefore, the policy for the promotion of HN service use will be important to achieve the ultimate goal of LTCI, which is to allow elderly people to live in their communities for as long as possible. © 2012 Japan Geriatrics Society.

It is unclear whether osteoporosis itself is a main risk factor for delayed wound healing after tooth extraction in humans. In this study, we evaluated the association between experience of delayed wound healing after last tooth extraction and self-reported kyphosis, with the possibility of having vertebral fractures, in Japanese patients. Among the 1,504 patients who responded to the structured questionnaire survey, 518 patients (134 men and 384 women) aged 55–97 years finally participated in this study. Patients who self-reported mild-moderate kyphosis were more likely to have problematic delayed wound healing after last tooth extraction than those who reported severe kyphosis (odds ratio [OR] 4.98; 95% confidence interval [CI], 1.86–13.38 and OR 2.30; 95% CI, 0.52–10.22, respectively) (p for trend = 0.005). Japanese patients with vertebral fractures may have a higher risk of having problematic delayed wound healing after tooth extraction. PMID:27848958

Introduction. Hypertension and cigarette smoking are dominant risk factors for cardiovascular disease in Japan while in westernized countries, broader effects encompass obesity, diabetes, and hypercholesterolemia. This paper examines whether different associations also appear important in the manifestation of activities of daily living (ADL) in older Japanese men in Hawaii and Japan. Methods. Measures of ADL (feeding, toileting, dressing, bathing, and walking around the house) were assessed from 1995 to 1999 in 1,893 men in Hawaii and 543 men in Japan. Concomitant risk factors were measured from 1990 to 1993. Results. In Hawaii, diabetes increased the odds of ≥1 ADL impairment nearly 1.5-fold (P = .020). A similar association was absent in Japan. In contrast, the odds of an ADL impairment in Japan was increased more than 5-fold in the presence of stroke (P < .001). The association in Hawaii was significantly weaker (P = .007). In both cohorts, past alcohol use was associated with a greater likelihood of ADL impairment. Conclusion. In this comparison of genetically similar samples, findings suggest that different strengths in risk factor associations with cardiovascular disease in Japan and westernized countries may also include different strengths in associations with impaired ADL.

Floorball training consists of intense repeated exercise and may offer a motivating and social stimulating team activity in elderly individuals. However, the effect of floorball training in elderly adults on physiological adaptations important for health is not known. Thus, this study examined the effect of floorball training on blood lipids, muscle strength, body composition, and functional capacity of men aged 65-76 years. Thirty-nine recreational active men were randomized into a floorball group (FG; n = 22) or petanque group (PG; n = 17), in which training was performed 1 h twice a week for 12 weeks. In FG and PG, average heart rate (HR) during training was 80% and 57%, respectively, of maximal HR. In FG, plasma low-density lipoprotein (LDL) cholesterol and triglycerides were 11% and 8% lower (P < 0.05), respectively. Insulin resistance determined by homeostatic model assessment (HOMA-IR) was reduced (P < 0.05) by 18%. HR during submaximal cycling was 5% lower (P < 0.05), and maximal voluntary contraction force was 8% higher (P < 0.05). Total and visceral fat content was lowered (P < 0.05) by 5% and 14%, respectively, HR at rest was 8% lower (P < 0.05) and performance in four different functional capacity tests were better (P < 0.05) after compared to before the training period. No changes were observed in PG. In conclusion, 12 weeks of floorball training resulted in a number of favorable effects important for health and functional capacity, suggesting that floorball training can be used as a health-promoting activity in elderly men. © 2016 John Wiley & Sons A/S.

Oral health-related quality of life (OHRQoL) is being increasingly used in epidemiologic studies of dentistry. However, patient-reported OHRQoL does not always coincide with clinical measures. Previous studies have shown a relationship between OHRQoL and personality, but did not concomitantly investigate oral function. We aimed to examine the association among personality traits, oral function, and OHRQoL using a large sample of community-dwelling Japanese elderly. The participants (n = 938; age, 69-71 years) were drawn from a complete enumeration of an urban area and a rural area of both the Tokyo metropolitan area and Hyogo Prefecture. The self-perceived impact of OHRQoL was measured using the Geriatric Oral Health Assessment Index (GOHAI). The oral status and socioeconomic characteristics were recorded in each participant, and personality traits (neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness) were assessed with the NEO-five-factor inventory. Multiple linear regression analysis was performed to examine the relationships between OHRQoL and other factors, with p < 0.05 considered to be statistically significant. Neuroticism was negatively associated with the GOHAI score in bivariate analyses (Spearman rank-order correlation coefficient (rs )= -0.20), whereas extraversion was positively associated (rs = 0.17). In the regression analyses, neuroticism (standardized partial regression coefficient (β) = -0.179) and extraversion (β=0.094) were significantly associated with the GOHAI scores independently of the number of teeth, maximal occlusal force, and financial status. Personality traits are associated with OHRQoL independently of objective measures of oral health status in community-dwelling elderly Japanese. This study showed personality traits are associated with OHRQoL independently of dental status and oral function in old Japanese people. As elderly patients undergo increasingly complex dental treatments, there is a

Japan has experienced pronounced population aging, and now has the highest proportion of elderly adults in the world. Yet few projections of Japan’s future demography go beyond estimating population by age and sex to forecast the complex evolution of the health and functioning of the future elderly. This study estimates a new state-transition microsimulation model – the Japanese Future Elderly Model (FEM) – for Japan. We use the model to forecast disability and health for Japan’s future elderly. Our simulation suggests that by 2040, over 27 percent of Japan’s elderly will exhibit 3 or more limitations in IADLs and social functioning; almost one in 4 will experience difficulties with 3 or more ADLs; and approximately one in 5 will suffer limitations in cognitive or intellectual functioning. Since the majority of the increase in disability arises from the aging of the Japanese population, prevention efforts that reduce age-specific morbidity can help reduce the burden of disability but may have only a limited impact on reducing the overall prevalence of disability among Japanese elderly. While both age and morbidity contribute to a predicted increase in disability burden among elderly Japanese in the future, our simulation results suggest that the impact of population aging exceeds the effect of age-specific morbidity on increasing disability in Japan’s future.

Penile carcinoma is a rare disease, accordingly there are few studies on molecular changes, and these results also vary greatly. A total of 26 penile squamous cell carcinomas in Japanese men were studied with respect to HPV, p53 alterations, and methylation of gene promoter region. HPV-DNA was detected in three of 26 patients (11.5%). Overexpression of p53 was observed in 13 of 26 patients (50%), and p53 gene mutations were detected in four of 26 patients (15.4%). The frequency of methylation was as follows: DAPK, 26.9% (7/26); FHIT, 88.4% (23/26); MGMT, 19.2% (5/26); p14, 3.8% (1/26); p16, 23.1% (6/26); RAR-beta, 23.1% (6/26); RASSF1A, 11.5% (3/26); and RUNX3, 42.3% (11/26). As for correlation between HPV and p53 alterations, and methylation status, mutations of the p53 gene were detected only in HPV-negative patients, and methylation was more frequently found in HPV-negative than in HPV-positive patients. The present results suggest that the majority of penile squamous cell carcinomas in Japanese men are unrelated to HPV, and gene alterations accumulate more frequently in HPV-unrelated penile carcinomas.

To identify metabolites showing changes in serum levels among Japanese male with diabetes. We performed metabolite profiling by coupling capillary electrophoresis with electrospray ionization time-of-flight mass spectrometry using fasting serum samples from Japanese male subjects with diabetes (n=17), impaired glucose tolerance (IGT; n=5) and normal glucose tolerance (NGT; n=14). Other than the expected differences in characteristics related to abnormal glucose metabolism, the percent body fat was significantly different among subjects with diabetes, IGT and NGT (27.3±6.2, 22.2±4.5 and 19.2±6.0%, respectively, p=0.0022). Therefore, percent body fat was considered as a possible confounding factor in subsequent analyses. Of 560 metabolites detected using our platform, the levels of 74 metabolites were quantified in all of the serum samples. Significant differences between diabetes and NGT were observed for 24 metabolites. The top-ranked metabolite was glycerol-3-phophate (glycerophosphate), which was significantly higher in subjects with diabetes than in those with NGT, even after Bonferroni correction for multiple testing (11.7±3.6 vs. 6.4±1.9 µM, respectively; corrected p=0.0222). Stepwise multiple regression analyses revealed that serum glycerophosphate levels were significantly correlated with 2-h plasma glucose after a 75-g oral glucose tolerance test (r=0.553, p=0.0005), independently of other characteristics, including FPG and HbA1c. Serum glycerophosphate levels were found to be elevated in Japanese men with diabetes, and correlated with 2-h PG, independent of FPG and HbA1c. Namely, serum glycerophosphate level at fasting condition can be a marker for predicting glucose intolerance. These results warrant further studies to evaluate the relevance of glycerophosphate in the pathophysiology of diabetes.

Background In Japan, more than 60% of employees are reported to suffer from anxiety and stress. Consequently, Japanese society has begun to address such important issues as psychogenic disability and job-related suicide. Furthermore, given the aging of society and the surge in the number of elderly people requiring care, it is necessary to adequately and proactively support employees who care for their elderly relatives. The purpose of the present study was to investigate caregiver burden in caring for elderly relatives and work-related stress factors associated with mental health among employees. Methods We studied 722 men and women aged 18–83 years in a cross-sectional study. The K10 questionnaire was used to examine mental health status. Results The proportion of participants with a high K10 score was 15% (n = 106). Having little conversation with their supervisor and/or coworkers significantly increased the risk of depression [odds ratio (OR) 1.8], as did high job overload (OR 2.7) and job dissatisfaction (OR 3.8), compared with employees who frequently conversed with their supervisor and/or coworkers. Caring for elderly relatives as a prominent characteristic of an employee was a significant risk factor for depression (OR 2.1). Conclusion The present study demonstrated that employees who were caring for elderly relatives were significantly associated with an increased risk of depression. To prevent depressive disorders, it may be important to focus on reducing the work-caregiving role conflict, as well as enhancing employees' job control and better rewarding their efforts in the workplace.

To analyze whether sex hormone levels predict the incidence of type2 diabetes among elderly Finnish men. This was a prospective population-based study, with a 9-year follow up period. The study population in the municipality of Lieto, Finland, consisted of elderly (age ≥64 years) men free of type 2 diabetes at baseline in 1998-1999 (n = 430). Body mass index and cardiovascular disease-adjusted hazard ratios and their 95% confidence intervals for type 2 diabetes predicted by testosterone, free testosterone, sex hormone-binding globulin, luteinizing hormone, and testosterone/luteinizing hormone were estimated. A total of 30 new cases of type 2 diabetes developed during the follow-up period. After adjustment, only higher levels of testosterone (hazard ratio for one-unit increase 0.93, 95% confidence interval 0.87-0.99, P = 0.020) and free testosterone (hazard ratio for 10-unit increase 0.96, 95% confidence interval 0.91-1.00, P = 0.044) were associated with a lower risk of incident type 2 diabetes during the follow up. These associations (0.94, 95% confidence interval 0.87-1.00, P = 0.050 and 0.95, 95% confidence interval 0.90-1.00, P = 0.035, respectively) persisted even after additional adjustment of sex hormone-binding globulin. Higher levels of testosterone and free testosterone independently predicted a reduced risk of type 2 diabetes in the elderly men. © 2014 Japan Geriatrics Society.

Orthostatic hypotension (OH) occurs when mechanisms regulating blood pressure (BP) levels after standing-up are altered. It is unclear how prevalence and risk factors for OH are different between sexes. We aimed to investigate sex differences in prevalence and risk factors for OH elderly individuals. We included 882 participants from Maracaibo Aging Study. OH was a sustained reduction of ≥20 mm Hg in systolic BP, ≥10 mm Hg in diastolic BP, or both, after 3 minutes of changing positions from supine to standing. Multivariable logistic regression models were used to examine the relationships among risk factors for OH in men and women considering interaction sex-term and stratified by sex. The mean age was 66.7 ± 8.5 years, being similar by sex. Women and men 55-74 years had similar prevalence of OH+ (18.5% vs. 20.9%, respectively). After 75 years, the proportion of women with OH+ was lower than men (11% vs. 30%, respectively). Hypertension, specifically systolic BP ≥140 mm Hg, and high pulse pressure (PP) were related with OH+ accounted by interaction sex-term, while diastolic BP ≥90 mm Hg, antihypertensive treatment, body mass index (BMI), diabetes mellitus and age were not. Systolic BP ≥140 mm Hg increases the risk of OH only among women, while BMI showed an inverse association in both sexes. Although the prevalence of OH is similar in both sexes, there are different risk factors associated by sex. Systolic BP ≥140 mm Hg was associated with increased risk of OH only with women while BMI was a protective factor for OH in men and women.

Elder abuse is a pervasive phenomenon around the world with devastating effects on the victims. Although it is not a new phenomenon, interest in examining elder abuse is relatively new. This paper aims to provide an overview of the aetiological theories and measures of elder abuse. The paper briefly reviews theories to explain causes of elder abuse and then discusses the most commonly used measures of elder abuse. Based on the reviewed theories, it can be concluded that elder abuse is a multifactorial problem that may affect elderly people from different backgrounds and involve a wide variety of potential perpetrators, including caregivers, adult children, and partners. The review of existing measurement instruments notes that many different screening and assessment instruments have been developed to identify elders who are at risk for or are victims of abuse. However, there is a real need for more measurements of elder abuse, as the current instruments are limited in scope. © 2013 The Authors. Psychogeriatrics © 2013 Japanese Psychogeriatric Society.

This study aimed to examine the acute effects of straight-leg raise (SLR) static stretching on passive stiffness and postural balance in healthy, elderly men. An additional aim of this study was to examine the relationships between stiffness and balance at baseline (prior to stretching) and the relationships between the stretch-induced changes in these variables. Eleven elderly men (age = 69 ± 6 years; height = 177 ± 7 cm; mass = 83 ± 13 kg) underwent postural balance and passive stiffness assessments before and after: 1) a stretching treatment consisting of four, 15-s SLR static stretches performed by the primary investigator and 2) a control treatment consisting of no static stretching. Passive stiffness was calculated from the slopes of the initial (phase 1) and final (phase 2) portions of the angle-torque curve. Unilateral postural balance was assessed on the right leg using a commercially designed balance testing device, which provides a measurement of static stability based on the overall stability index (OSI). The slope coefficients and OSI values decreased from pre- to post-treatment for the stretching intervention (P = 0.015 and 0.018, respectively); however, there were no changes for the control (P = 0.654 and 0.920). For the stretching intervention, a significant positive relationship was observed between OSI and the slope coefficient of phase 1 at baseline (r = 0.619; P = 0.042). A significant positive relationship was also observed between the stretched-induced changes in OSI and the slope coefficient of phase 1 (r = 0.731; P = 0.011). No relationship was observed between OSI and the slope coefficient of phase 2 at baseline (r = 0.262; P = 0.437) nor was there a relationship between the changes in these variables (r = 0.419; P = 0.200). A short, practical bout of SLR static stretching may be an effective intervention for reducing passive stiffness and improving postural balance in healthy, elderly men.

To assess the effect of dietary patterns on all deaths and diabetes-related deaths in the Japanese Elderly Diabetes Intervention Trial (J-EDIT). We investigated relationships between that of overall mortality and dietary pattern, and diabetes-related deaths and dietary pattern as observed among 912 registered cases of the J-EDIT study, which is a prospective follow-up study of elderly Japanese type 2 diabetic patients. Factor analysis with the factor number 3 led to deriving three dietary patterns (healthy type, snack type and greasy type). The relationship between these patterns and overall mortality or diabetes-related death was investigated. Although not statistically significant, there was a lower tendency of overall mortality and diabetes-related deaths for the healthy type dietary pattern. When the tendencies of overall mortality were analyzed for "young-old," who are younger than 75 years-of age, and "old-old" of over 75 years-of-age, the mortality rate for the greasy type and healthy type dietary patterns were nearly the same and higher than the snack type dietary pattern in young-old. In contrast, in old-old, a higher mortality rate was reported for the greasy type dietary pattern and a lower mortality rate was reported for the healthy type dietary pattern. The hazard ratio by Cox regression analysis for greasy type to healthy type in old-old was 3.03 (P = 0.04, CI 1.07-8.57). Furthermore, in old-old, as vegetable consumption increased, the lower the tendency foroverall mortality, and the more fish that was consumed, the overall mortality significantly decreased (P = 0.020) in the tertile. The greasy type dietary pattern with an increased amount of sugar, fat and meat led to poor life prognosis for elderly Japanese type 2 diabetic patients. The healthy type dietary pattern rich in vegetable and fish, which is similar to the Mediterranean diet and Dietary Approach to Stop Hypertension diet, was suggested to improve life prognosis. © 2012 Japan Geriatrics

Primary androgen deprivation therapy (pADT) is commonly used to treat elderly men diagnosed with localized prostate cancer (CaP), despite the lack of evidence supporting its use. To examine the effect of pADT on mortality and to assess contemporary trends of pADT use in elderly men with CaP. Men older than 65 yr residing in Surveillance, Epidemiology, and End Results (SEER) registry areas diagnosed with localized or locally advanced CaP between 1992 and 2009 and not receiving definitive therapy. Propensity score (PS)-weighted Cox proportional hazards models were used to estimate the effect of pADT use on overall survival among patients receiving pADT. The interaction between comorbidity-adjusted life expectancy (LE) and pADT use was assessed within the Cox and PS-weighted models. Contemporary (2004-2009) trends for pADT use were analyzed by linear regression. The primary cohort included 46 376 men, of whom 17 873 received pADT (39%). Patients with >10 yr LE had lower pADT utilization rates than patients with short LE. Between 2004 and 2009, the use of pADT in men with localized CaP decreased by 14% (from 36% to 22%). Relative to observation, pADT was associated with a survival disadvantage, with a hazard ratio for all-cause mortality of 1.37 (95% confidence interval 1.20-1.56). Limitations included biases not accounted for by the PS-weighted model, changes in CaP staging over the study period, the absence of prostate-specific antigen (PSA) data prior to 2004, and the limits of retrospective analysis to demonstrate causality. The use of pADT in elderly men with localized CaP has decreased over time. For men forgoing primary definitive therapy, the use of pADT is not associated with a survival benefit compared to observation, and denies men an opportunity for cure with definitive therapy. The deleterious effect of pADT is most pronounced in men with prolonged LE. In this report, we assessed the effect of primary androgen deprivation (pADT) on prostate cancer

Cross-sectional associations between lifestyle and serum lipid levels were examined in 1591 Japanese male office workers aged 35 to 59 years in Osaka, Japan. From multiple linear regression analyses, significant correlates with low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and Log triglyceride levels and the ratio of LDL cholesterol to HDL cholesterol were, in the order of relative importance: BMI, alcohol intake (negative) and age for LDL cholesterol level; BMI (negative), cigarette smoking (negative), alcohol intake, consideration for nutritional balance, hours of brisk walking, hours of walking at an ordinary pace and physical exercise for HDL cholesterol level; BMI, cigarette smoking, consideration for nutritional balance (negative), hours of work (negative), alcohol intake and coffee drinking (negative) for Log triglyceride level; and BMI, alcohol intake (negative), cigarette smoking, consideration for nutritional balance (negative), age, hours of brisk walking (negative) and the frequency of snack intake between meals for the ratio of LDL cholesterol to HDL cholesterol. Our data suggest that obesity, cigarette smoking and snack intake between meals are atherogenic whereas alcohol consumption, consideration for nutritional balance and walking long hours, especially at a brisk pace, are anti-atherogenic in middle-aged Japanese men.

The objective was to describe influences of sex hormones on the male voice in an elderly cohort. Sixty-three elderly males were recruited to undergo assessment of voice parameters, stroboscopy, voice-related questionnaires, a blood draw, and an ultrasound examination of the laryngeal skeleton. The group was divided into men with normal hormonal status and men with lowered levels of sex hormones, called hypogonades. Depending on the level of androgens, voice parameters did not differ. In subjects with decreased levels of estrogens, a significant increase in mean fundamental frequency, as well as changes of highest and lowest frequency plus a shift of the frequency range could be detected. We could detect significant changes of voice parameters depending on status of estrogens in elderly males. Androgens appear to have no impact on the elderly male voice. To our knowledge, this is the first prospective study that correlates sex hormones with voice parameters in elderly men. (c) 2010 The Voice Foundation. Published by Mosby, Inc. All rights reserved.

Human aging is accompanied by a decrease in growth hormone secretion and serum IGF-1 levels. Also, loss of muscle mass, strength and impairment of physical performance, ending in a state of frailty, are seen in elderly. We aimed to investigate whether handgrip strength, physical performance and recurrent falls are related to serum IGF-1 levels in community dwelling elderly. Observational cohort study (cross-sectional and prospective). We studied the association between IGF-1 and handgrip strength, physical performance and falls in participants of the Longitudinal Aging Study Amsterdam. 1292 participants were included (633 men, 659 women). Serum IGF-1 levels were divided into quartiles (IGF-1-Q1 to IGF-1-Q4). Data on falls were collected prospectively for a period of three years. All analyses were stratified for age and physical activity and adjusted for relevant confounders. Men with a low physical activity score in IGF-1-Q1 and IGF-1-Q2 of the younger age group had a lower handgrip strength compared to IGF-1-Q4. In younger more active males in IGF-1-Q2 physical performance was worse. Recurrent fallers were less prevalent in older, low active males with low IGF-1 levels. In females, recurrent fallers were more prevalent in older, more active females in IGF-1-Q2. IGF-1 quartile may predict changes in handgrip strength and physical performance in men and women. Our results indicate that lower IGF-1 levels are associated with lower handgrip strength and worse physical performance, but less recurrent fallers especially in men. Associations were often more robust in IGF-1-Q2. Future studies on this topic are desirable.

Considerable attention has been paid to the association between type 2 diabetes mellitus (T2DM) and cognitive dysfunction in the elderly. T2DM is often comorbid with several other metabolic disturbances, including hypertension and dyslipidemia. These comorbid diseases might be associated with cognitive impairment. Many clinical indices should be included as variables for the association with cognitive decline. In the current study, we tried to identify the associated factors with cognitive decline during a 6-year period in elderly T2DM considering the changes in the clinical indices during the follow-up period. The subjects in the present study were 63 Japanese Elderly Interventional Trial participants who were administered the Mini-Mental State Examination at baseline, at the third year, and at the end of the 6-year follow-up period. We applied the pooled logistic analysis method to consider the changes in clinical indices during the observation period and tried to identify the factors associated with cognitive decline during the 6 years in elderly type 2 diabetics using repeated measured data for glycated hemoglobin A1c, blood pressure and serum lipids. In the current study, low high-density lipoprotein-cholesterol and higher diastolic blood pressure were significantly associated with cognitive decline by pooled logistic analysis in the 6-year observation of older diabetic subjects. Higher glycated hemoglobin A1c had a tendency toward association with cognitive decline. The results suggest that comprehensive management of diabetes, including dyslipidemia and hypertension, might contribute to the prevention of declines in cognitive function in older diabetic patients. © 2012 Japan Geriatrics Society.

The present analysis was restricted to 22,224 men who were 40-65 years of age at baseline (1988-1990) and who reported working full time or were self-employed in the JACC Study. The subjects were followed through 31 December 2009. Information on occupation and lifestyle factors was collected using a self-administered questionnaire. The Cox proportional hazards model was used to estimate the relative risk (RR) and 95% confidence interval (CI) for the risk of death from pancreatic cancer in relation to shift work. During the follow-up period, 127 pancreatic cancer deaths were observed. Overall, we found no statistically significant increase in the risk of death from pancreatic cancer associated with rotating shift work. As compared to day-shift workers, the RRs were 0.83 (95% CI 0.43-1.60) for rotating shift workers and 0.61 (95% CI 0.22-1.60) for fixed night-shift workers, after adjustment for potential confounding factors. The multivariable-adjusted RR was 1.34 (95% CI 0.66-2.75) among rotating shift workers in the analysis restricted to men who reported working full time at baseline. Our data did not support the hypothesis that shift work is significantly associated with the risk of death from pancreatic cancer in this cohort of Japanese men.

This study investigated cardiorespiratory responses and rating of perceived exertion (RPE) during prolonged walking and running exercise performed at the walk-run transition speed (WRTS) in untrained healthy elderly men. 20 volunteers (mean±SE, age: 68.4±1.2 yrs; height: 170.0±0.02 cm; body mass: 74.7±2.3 kg) performed the following bouts of exercise: a) maximal cardiopulmonary exercise test (CPET); b) specific protocol to detect WRTS; and c) two 30-min walking and running bouts at WRTS. Expired gases were collected during exercise bouts via the Ultima CardiO 2 metabolic analyzer. Compared to walking, running at the WRTS resulted in higher oxygen uptake (>0.27 L·min -1 ), pulmonary ventilation (>7.7 L·min -1 ), carbon dioxide output (>0.23 L·min -1 ), heart rate (>15 beats·min -1 ), oxygen pulse (>0.88 15 mL·beats -1 ), energy expenditure (>27 kcal) and cost of oxygen transport (>43 mL·kg -1 ·km -1 ·bout -1 ). The increase of overall and local RPEs with exercise duration was similar across locomotion modes (P<0.001). In all participants, %HRR and %VO 2 R throughout walking and running bouts were around or above the gas exchange threshold. In conclusion, elderly men exhibited higher cardiorespiratory responses during 30-min bouts of running than walking at WRTS. Nevertheless, walking corresponded to relative metabolic intensities compatible with preservation or improvement of cardiorespiratory fitness and should be preferable over running at WRTS in the untrained elderly characterized by poor fitness and reduced exercise tolerance. © Georg Thieme Verlag KG Stuttgart · New York.

It has been suggested that physical or social activity is associated with fewer sleep disturbances among elderly people. Women report more sleep disturbances than men, which could indicate a variation in activity patterns between the genders. The aim of this study was to investigate associations between sleep disturbances and leisure activities in men and women (n = 945) aged ≥60 years in a Swedish population. Sleep disturbances were measured using eight dichotomous questions and seventeen variables, covering a wide range of leisure activities. Few leisure activities were found to be associated with sleep disturbances and their importance decreased when the models were adjusted for confounders and gender interactions. After clustering the leisure activities and investigating individual activities, sociointellectual activities were shown to be significant for sleep. However, following adjustment for confounders and gender interactions, home maintenance was the only activity significant for sleep. Being a female increased the effect of home maintenance. Besides those leisure activities, poor/fair self-rated health (OR 7.50, CI: 4.27–11.81) and being female (OR 4.86, CI: 2.75–8.61) were found to have the highest association with poor sleep. Leisure activities pursued by elderly people should focus on activities of a sociointellectual nature, especially among women, to promote sleep. PMID:24575303

Studies from Western countries suggest that smokers tend to display greater abdominal obesity than non-smokers, despite showing lower weight. Whether this holds true in a leaner population requires clarification. Using indices of abdominal obesity including visceral adipose tissue, we examined whether lifetime cigarette smoking is associated with unfavorable fat distribution among Japanese men. From 2006 to 2008, we conducted a cross-sectional investigation of a community-based sample of Japanese men at 40-64 years old, free of cardiovascular diseases and cancer. Areas of abdominal visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) were calculated using computed tomography. We divided participants into four groups: never-smokers; and tertiles of pack-years of smoking among ever-smokers. Using multivariable linear regression, we calculated adjusted means of obesity indices (VAT, SAT, VAT-SAT ratio [VSR], and waist-hip ratio [WHR]) for each group, and mean differences between consecutive groups. We analyzed 513 men (median age, 58.2 years; current smokers, 40.1%). Two-thirds showed body mass index (BMI) < 25 kg/m(2) (median, 23.5 kg/m(2)). Overall, greater lifetime smoking group was associated with greater WHR and VSR. On average, one higher smoking group was associated with 0.005 higher WHR (95% CI, 0.001-0.008; P = 0.005) and 0.041 greater VSR (95% CI, 0.009-0.073; P = 0.012) after adjustment for potential confounders, including BMI. In this sample of relatively lean Japanese men, greater lifetime smoking was associated with a metabolically more adverse fat distribution. Although smoking is commonly associated with lower BMI, minimizing the amount of lifetime smoking should be advocated.

A population-based radiographic study with longitudinal follow-up. To develop a quantitative index for lumbar disc space narrowing (DSN) evaluation in elderly subjects; to determine how DSN in the elderly is influenced by osteoporosis and sex. There is paucity of research on quantitative classification of lumbar DSN based on disc areal morphometry. With the database of Osteoporotic Fractures in Men (Hong Kong) and Osteoporotic Fractures in Women (Hong Kong) Studies and those who attended the year-4 follow-up (n = 1519 for men and n = 1546 for women), data of 491 women and 592 men were randomly selected. The anterior, middle, and posterior heights; anteroposterior diameter; and area of intervertebral discs (T4T5 to L4L5) were measured on lateral radiographs. Disc area index for lumbar spine (DAIL, disc area divided by the mean of the sum of square of the adjacent upper and lower vertebrae mid-height anterior-posterior diameter) was developed and compared with semiquantitative DSN expert grading. DAIL correlated with semiquantitative grading, with sensitivity and specificity varying from 87.3% to 96.8% for grade 1 DSN (<30% reduction in disc height), and 92.9% to 100% for grade 3 DSN (>60% reduction in disc height). The thoracolumbar disc area loss among men and women during 4-years' follow-up period varied between 1.32% and 3.56%, and it was greater for women (mean: 2.44%) than for men (mean: 1.90%, P = 0.044). Majority of lumbar DSN progressions during 72 to 76 years old were progression from normal disc space to grade 1 DSN. Osteoporosis was associated with greater disc area decrease, both for thoracic and lumbar discs. Lumbar DSN can be quantified using DAIL. In elderly Chinese, intervertebral disc narrowing over a 4-year period was greater in women than men, and associated with the presence of osteoporosis. 3.

We carried out a cross-sectional study investigating the association between health-related quality of life (HRQOL) and voice, as evaluated by an acoustic analysis, in elderly residents of a nursing home. The HRQOL of 61 elderly nursing home residents (mean age: 82.1±8.3 years) was assessed via the SF-8 Health Survey questionnaire, Japanese version (SF-8). The subjects' voices were recorded and analyzed by a voice assessment software program, which calculated the pitch period perturbation quotient (PPQ), amplitude perturbation quotient (APQ), and noise-to-harmonic ratio (NHR). Subjects who scored under the 25th percentile on general health (GH), vitality (VT), or physical summary (PCS) in the SF-8 showed significantly higher PPQ, APQ, and NHR scores in comparison to their counterparts (p<0.05). After adjustment for age, lower GH scores were found to be associated with higher PPQ, APQ, and NHR scores; lower VT scores were associated with higher APQ and NHR scores; and lower PCS scores were associated with higher APQ and NHR scores (p<0.05). The results of the acoustic analysis indicated that voice was associated with HRQOL in the elderly nursing home residents of the present study. Among the acoustic parameters that were analyzed, PPQ, APQ, and NHR may be an influential factor that can be used to assess HRQOL, independently of the effects of age, in elderly individuals.

Low testosterone has been associated with hip fracture in men in some studies. However, data on other hormonal parameters and fracture outcome in men is minimal. This study examined the association between free testosterone (free T) estradiol (E2), sex hormone-binding globulin (SHBG), 25-hydroxyvitamin D [25(OH)D], parathyroid hormone (PTH), insulin-like growth factor I (IGF-I), and fracture in 437 elderly community-dwelling men. Age, height, weight, quadriceps strength, femoral neck bone mineral density (FN BMD), and fracture data (1989-1997) also were obtained. Fractures were classified as major (hip, pelvis, proximal tibia, multiple rib, vertebral, and proximal humerus) or minor (remaining distal upper and lower limb fractures). Fifty-four subjects had a fracture (24 major and 30 minor). There was no association between minor fractures and any hormonal parameter. Risk of major fracture was increased 2-fold for each SD increase in age, decrease in weight and height, and increase in SHBG, and risk of major fracture was increased 3-fold for each SD decrease in quadriceps strength, FN BMD, and 25(OH)D (univariate logistic regression). Independent predictors of major fracture were FN BMD, 2.7 (1.5-4.7; odds ratio [OR]) and 95% confidence interval [CI]); 25(OH)D, 2.8 (1.5-5.3); and SHBG, 1.7 (1.2-2.4). An abnormal value for three factors resulted in a 30-fold increase in risk but only affected 2% of the population. It is not immediately apparent how 25(OH)D and SHBG, largely independently of BMD, may contribute to fracture risk. They may be markers for biological age or health status not measured by methods that are more traditional and as such may be useful in identifying those at high risk of fracture.

Leptin, the adipocyte-secreted protein product of the ob gene, has been strongly linked to obesity and is believed to play a role in the regulation of the reproductive system. This study examines the potential influence of lifestyle and dietary factors, as well as of other hormones, on serum levels of leptin. The authors studied a population of 48 healthy elderly Greek men. Sera from these men were analyzed for leptin, several steroid hormones, sex hormone-binding globulin, and insulin-like growth factor 1. The authors also utilized data from food frequency questionnaires and information on demographic, anthropometric, and lifestyle (cigarette smoking, alcohol and coffee drinking) factors. Using linear regression modeling, serum leptin levels were inversely associated with testosterone and positively associated with estradiol and dehydroepiandrosterone sulfate, after adjustment for the other hormones and body mass index (BMI). Leptin levels in men with a BMI >30 kg/m2 were 170% higher than in men with a BMI <27 kg/m2 (95% CI 63- 346%). Height was also positively associated with leptin, independent of BMI. No notable relationships were observed between leptin, on the one hand, and smoking, alcohol drinking, coffee drinking, or total energy intake, on the other. When total energy intake was separated into its three major components (carbohydrate, fat, and protein), it appeared that fat intake may have an isocalorically differential effect on serum leptin levels; one marginal quintile increase in fat intake corresponded to an 11% increase in leptin (95% CI 0-24%). Serum levels of leptin may be influenced by other endocrine factors, especially testosterone and estradiol, and may be positively associated with excess fat intake independently of obesity.

The role of plasma estradiol in the accumulation of intra-abdominal fat (IAF) in men is uncertain. Cross-sectional studies using imaging of IAF have shown either a positive or no association. In contrast, a randomised controlled trial using an aromatase inhibitor to suppress estradiol production found an association between oestrogen deficiency and short-term IAF accumulation. No longitudinal study has been conducted to examine the relationship between plasma estradiol concentration and the change in IAF area measured using direct imaging. This is a longitudinal observational study in community-dwelling Japanese-American men (n=215, mean age 52 years, BMI 25.4kg/m 2 ). IAF and subcutaneous fat areas were assessed using computerized tomography (CT) at baseline, 5 and 10 years. Baseline plasma estradiol concentrations were measured using liquid chromatography-tandem mass spectrometry. Univariate analysis found no association between baseline estradiol concentration and baseline IAF, or 5- or 10-year changes in IAF area (r=-0.05 for both time points, p=0.45 and p=0.43, respectively). Multivariate linear regression analysis of the change in IAF area by baseline estradiol concentration adjusted for age, baseline IAF area, and weight change found no association with either the 5- or 10-year IAF area change (p=0.52 and p=0.55, respectively). Plasma estradiol concentration was not associated with baseline IAF nor with change in IAF area over 5 or 10 years based on serial CT scans in community-dwelling Japanese-American men. These results do not support a role for oestrogen deficiency in IAF accumulation in men. Copyright © 2015 Asia Oceania Association for the Study of Obesity. All rights reserved.

Background Depression is a common mental disorder. Several studies suggest that lifestyle and health status are associated with depression. However, only a few large-scale longitudinal studies have been conducted on this topic. Methods The subjects were middle-aged and elderly Japanese adults between the ages of 40 and 69 years. A total of 9,650 respondents completed questionnaires for the baseline survey and participated in the second wave of the survey, which was conducted 7 years later. We excluded those who complained of depressive symptoms in the baseline survey and analyzed data for the remaining 9,201 individuals. In the second-wave survey, the DSM-12D was used to determine depression. We examined the risks associated with health status and lifestyle factors in the baseline survey using a logistic regression model. Results An age-adjusted analysis showed an increased risk of depression in those who had poor perceived health and chronic diseases in both sexes. In men, those who were physically inactive also had an increased risk of depression. In women, the analysis also showed an increased risk of depression those with a BMI of 25 or more, in those sleeping 9 hours a day or more and who were current smokers. A multivariate analysis showed that increased risks of depression still existed in men who had chronic diseases and who were physically inactive, and in women who had poor perceived health and who had a BMI of 25 or more. Conclusions These results suggest that lifestyle and health status are risk factors for depression. Having a chronic disease and physical inactivity were distinctive risk factors for depression in men. On the other hand, poor perceived health and a BMI of 25 or more were distinctive risk factors for depression in women. Preventive measures for depression must therefore take gender into account.

Investigations of human papillomavirus (HPV) in the glans penis are scarce, especially with regard to its natural history. To elucidate HPV prevalence among Japanese men attending urological clinics, 798 adult participants were recruited consecutively and stratified into groups by age based on 10-year intervals. The overall HPV prevalence among the participants was 24.8%, with 15.5% positive for high-risk HPV and 9.3% infected with other HPVs. The HPV positivity rate was sustained in those over 80 years of age at nearly the same level as those in the younger age groups. We also determined the age at last sexual intercourse of 15 HPV-positive participants in the 80+ years age group. In addition, six participants positive for HPV were re-examined for HPV and all showed nearly the same HPV types as those identified in their first examinations. The difference between the age at the first test and the age of last intercourse was 8.3 ± 6.2 years. Except for the elderly group who reported sexual intercourse within the previous year, the duration was 10.0 ± 5.1 years. Our data suggest an HPV persistence of at least eight years. Further investigation is necessary to elucidate the long-term persistence of HPV infection in the glans penis.

Yellow tongue coating is one of the clinical signs for diabetes mellitus according to traditional East Asian medicine. Few reports have been available on the association between yellow tongue coating and the prevalence of type 2 diabetes in the general population. We examined that association among population samples of non-smoking men and women. The study subjects were Japanese non-smoking men (n = 315) and women (n = 654) aged 30-79 years who resided in Toon city and participated in the Toon Health Study from July 2011 through November 2014. Tongue coating was assessed by a nationally licensed acupuncturist and classified into three categories of white (normal), light yellow, and yellow. We performed an oral glucose tolerance test to confirm the presence of diabetes mellitus and prediabetes. The associations between yellow tongue coating and the prevalence of diabetes mellitus and prediabetes were examined using multivariable logistic regression analyses, adjusting for age, sex, body mass index, drinking status, and physical activity. The multivariable odds ratios of diabetes mellitus were 1.39 (95% confidence interval [CI], 0.72-2.67) for light yellow tongue coating and 2.23 (95% CI, 1.16-4.30) for yellow tongue coating compared with white tongue coating. The respective multivariable odds ratios of prediabetes were 1.13 (95% CI, 0.80-1.61) and 1.43 (95% CI, 0.96-2.12). Yellow tongue coating was associated with higher prevalence of diabetes mellitus and tended to be associated with that of prediabetes among Japanese non-smoking men and women.

We aimed to investigate the association between reduced lung function and cerebral small vessel diseases via cranial magnetic resonance imaging (MRI) in the cross-sectional study of the general Japanese population. We recruited participants aged ≥40 years from the general population of a single city in Japan. We clarified the comorbidities and treatments, smoking habits, second-hand smoke exposure, current alcohol consumption, education level, exercise habits, and occupation. The pulmonary function test was performed to assess the forced expiratory volume in 1 second (FEV 1 ) % predicted and forced vital capacity (FVC) % predicted values. Cranial MRI was performed to evaluate the white matter lesions (WMLs) and lacunar infarcts. We examined the association of the WMLs and lacunar infarcts with a 1-standard deviation (SD) lower in the FEV 1 % predicted and FVC % predicted, on the basis of the smoking status. A total of 473 men were examined. The association of WMLs and lacunar infarcts with the spirometry-based indices were significant only in never smokers. The association between lung function impairment and cerebral small vessel disease did not change after further adjusting for second-hand smoke exposure. In a community-based sample of Japanese men, we found an association between reduced lung function and WMLs and lacunar infarcts in never smokers.

Minoxidil is efficacious in inducing hair growth in patients with androgenetic alopecia by inducing hair follicles to undergo transition from the early to late anagen phase. Although the efficacy of 1% topical minoxidil has been confirmed in Japan, no controlled study of 5% topical minoxidil has been conducted using male Japanese subjects. The objective of this trial was to verify the superiority in clinical efficacy of 5% topical minoxidil to 1% topical minoxidil in a double-blind controlled study with male, Japanese androgenetic alopecia patients as the subjects. The trial included 300 Japanese male patients aged 20 years or older with androgenetic alopecia who were administered either 5% topical minoxidil (n = 150) or 1% topical minoxidil (n = 150) for 24 weeks. The mean change from the baseline in non-vellus hair/cm(2), the primary efficacy variable, was 26.4 (n = 142) in the 5% topical minoxidil group and 21.2 (n = 144) in the 1% topical minoxidil group at 16 weeks, the main time point for the evaluation. The difference between the groups was significant (P = 0.020). The incidence of adverse events was 8.7% (13/150) in the 5% group and 5.3% (8/150) in the 1% group, with no significant difference between the groups (chi(2)-test: P = 0.258). Our findings confirmed the superiority of 5% topical minoxidil to 1% topical minoxidil in treating Japanese men with androgenetic alopecia.

Background Hypertension is developed easily in Asian adults with normal body mass index (BMI) (~23 kg/m2), compared with other ethnicities with similar BMI. This study tested the hypothesis that slightly increased BMI at young age is a risk factor for future hypertension in Japanese men by historical cohort study. Methods The study participants were 636 male alumni of the physical education school. They had available data on their physical examination at college age and follow-up investigation between 2007 and 2011. The participants were categorized into six categories: BMI at college age of <20.0 kg/m2, 20.0–21.0kg/m2, 21.0–22.0kg/m2, 22.0–23.0kg/m2, 23.0–24.0kg/m2, and ≥24.0kg/m2, and the incidence of hypertension was compared. Results This study covered 27-year follow-up period (interquartile range: IQR: 23–31) which included 17,059 person-years of observation. Subjects were 22 (22–22) years old at graduated college, and 49 (45–53) years old at first follow-up investigation. During the period, 120 men developed hypertension. The prevalence rates of hypertension for lowest to highest BMI categories were 9.4%, 14.6%, 16.1%, 17.5%, 30.3%, and 29.3%, respectively (p<0.001 for trend), and their hazard ratios were 1.00 (reference), 1.80 (95%CI: 0.65–4.94), 2.17 (0.83–5.64), 2.29 (0.89–5.92), 3.60 (1.37–9.47) and 4.72 (1.78–12.48), respectively (p<0.001 for trend). This trend was similar after adjustment for age, year of graduation, smoking, current exercise status and current dietary intake. Conclusion Slightly increased BMI at young age is a risk factor for future hypertension in Japanese men. PMID:29324821

Lipid accumulation product (LAP) is a new continuous marker of lipid overaccumulation that predicts cardiovascular risk. The aim of this study was to determine the cutoff value for LAP and evaluate its usefulness. Using a database of results of health checkup examinations for 10,170 Japanese workers (35-40 years of age) conducted at their workplaces, the cutoff value for a high LAP was calculated by analyzing receiver-operating characteristic (ROC) curves for the relationships of LAP with hyperglycemia and diabetes. The cutoff value for LAP was 21.1 for women and 37.2 for men. The values were similar when calculated by analyzing the ROC curves for the relationships with hyperglycemia and diabetes. Using these cutoff values, the prevalence of a high LAP was calculated to be 23.7% in women and 28.8% in men. The odds ratio for diabetes in the subjects with vs. those without a high LAP, calculated after adjusting for age, smoking, alcohol consumption and regular exercise, was 19.09 (95% CI: 6.57-55.50) in women and 7.40 (95% CI: 5.10-10.75) in men. High odds ratios for hypertension (10.66 [95% CI: 7.77-14.63] in women and 7.31 [95% CI: 6.20-8.62] in men) were also obtained in the subjects with vs. those without a high LAP. Cutoff values for a high LAP in women and men were determined, and high odds ratios for diabetes and hypertension were obtained using the cutoff values for LAP. Further studies are needed to elucidate whether the proposed cutoff values are applicable to people of other ages, races and ethnicities.

To examine the prevalence of herniation pits (HPs) and to evaluate differences in radiographic features related to femoroacetabular impingement-a hip disorder with abnormal abutment between the acetabulum and femur-between hips with and without HPs in a convenience sample of Japanese patients. We reviewed 1,178 hips on each side (695 men, 483 women; mean age, 58.2 years) using computed tomographic images. The radiological assessments of hip morphology were performed by measuring the lateral center edge angle, acetabular index, acetabular version, alpha angle, and femoral head-neck offset. HPs were defined as the round or oval cystic lesions surrounded by sclerotic bone located below the anterior femoral neck cortex. Intraclass and interclass reproducibility of all radiographic measurements was acceptable (ICC: 0.71-0.98). The prevalence of HPs was 13.9 % in all subjects and was significantly higher in men (18.1 %) than in women (7.8 %; p < 0.001). HPs were larger in male (p < 0.001) and elderly subjects (p < 0.005). In subjects with HPs, the alpha angle was larger and femoral head-neck offset and offset ratio were smaller in the cohort overall and in men. Logistic regression analysis revealed the association between radiological cam-type FAI and HPs in all subjects (odds ratio: 1.86, p < 0.001). We revealed the prevalence of HPs and showed it has a predilection for men in this Japanese cohort. Femoral head asphericity or small head-neck offset was more common in subjects with HPs than those without HPs.

Gender disparity in health and diseases is increasingly being recognised. Therefore, it was decided to investigate gender differences in the elderly subjects (60+years) from a community-based study. The study was undertaken to evaluate the oral health status and treatment needs of urban and rural elderly and to study the impact of socio-demographic variables on them. An urban area in South Delhi and its adjoining four villages was selected. A modified WHO-Oral Health Survey proforma and Rup-Nagpal's scale were used to record oral health and socio-demographic data respectively. In addition, diet pattern (vegetarian/non-vegetarian) and body mass index (BMI) were also recorded. Chi square test and p values were calculated for each of the studied parameters. There were significant differences for socio-economic status, literacy level, marital and family status between elderly men and women (p<0.0001). A higher percentage of elderly women were vegetarian and overweight than elderly men (p<0.01). However, there were few differences found in the prevalence of dental caries, periodontal diseases and edentulousness between male and female elderly (p>0.01). The only difference found was in the evidence of previous dental treatment received. Elderly men had a higher percentage of filled teeth and denture wear compared to elderly women (p<0.01). Women's oral health is significantly influenced by social, economic and psychological factors.

IXIARO® is a Vero cell-derived, inactivated Japanese encephalitis (JE) vaccine licensed mainly in western countries for children and adults traveling to JE endemic areas. Limited immunogenicity and safety data in elderly travelers have been available. To evaluate safety and immunogenicity of IXIARO in elderly subjects. Open-label, single arm, multi-centered study. Two-hundred subjects with good general health, including adequately controlled chronic conditions, received two doses of IXIARO®, 28days apart. Protective levels of antibodies were tested 42days after the second dose. Systemic and local adverse events (AEs) were solicited for 7days after each dose, unsolicited AEs were collected up to day 70 and in a phone call at month 7. Subjects were aged 64-83years (median 69.0years). Nineteen percent of subjects had serious or medically attended AEs up to Day 70 (primary endpoint), none of them causally linked to IXIARO. Solicited local AEs were reported by 33.5% (most common: local tenderness) and solicited systemic AEs by 27% (most common: headache) of subjects. The seroprotection rate was 65% with a geometric mean titre (GMT) of 37. Subjects with tick borne encephalitis (TBE) vaccinations in the past 5years (N=29) had a SCR of 90% and GMT of 65. IXIARO is generally well tolerated in the elderly, and the safety profile is largely comparable with younger adults. SCR and GMT are lower compared to younger adults, but SCR is in the range reported in elderly for other vaccines e.g. against TBE, hepatitis-A virus (HAV)/hepatitis-B virus (HBV), influenza. The differences in SCR and GMT from younger to elderly adults were in the range of other vaccines. Duration of protection is uncertain in older persons, therefore a booster dose (third dose) should be considered before any further exposure to JE virus. Copyright © 2016. Published by Elsevier Ltd.

Orthostatic intolerance and falls differ between sexes and change with age. However, it remains unclear what role cerebral autoregulation may play in this response. This study was designed to determine whether cerebral autoregulation, assessed using transcranial Doppler ultrasound, is more effective in elderly females than in males. We used transcranial Doppler ultrasound to evaluate cerebral autoregulation in 544 (236 male) subjects older than age 70 years recruited as part of the MOBILIZE Boston study. The MOBILIZE Boston study is a prospective cohort study of a unique set of risk factors for falls in seniors in the Boston area. We assessed CO2 reactivity and transfer function gain, phase, and coherence during 5 minutes of quiet sitting and autoregulatory index during sit-to-stand tests. Male subjects had significantly lower CO2 reactivity (males, 1.10 ± 0.03; females, 1.32 ± 0.43 (cm/s)/%CO2; P<0.001) and autoregulatory indices (males, 4.41 ± 2.44; female, 5.32 ± 2.47; P<0.001), higher transfer function gain (males, 1.34 ± 0.49; females, 1.19 ± 0.43; P=0.002), and lower phase (males, 42.7 ± 23.6; females, 49.4 ± 24.9; P=0.002) in the autoregulatory band, implying less effective cerebral autoregulation. However, reduced autoregulation in males was not below the normal range, indicating autoregulation was intact but less effective. Female subjects were better able to maintain cerebral flow velocities during postural changes and demonstrated better cerebral autoregulation. The mechanisms of sex-based differences in autoregulation remain unclear but may partially explain the higher rates of orthostatic hypotension-related hospitalizations in elderly men.

Japanese social security systems and institutions for the elderly, as well as the general attitude toward elderly care services among the Japanese population, have been undergoing a dramatic change. By examining the association between institutional trust, which is a representative element of social capital, and anxiety regarding receiving elderly care, we can uncover clues toward building a more robust social security system for the elderly. This study examines the relationship between institutional trust, in the national social security and municipal healthcare systems for the elderly, and anxiety with respect to receiving elderly care among the general Japanese population. A cross-sectional survey was conducted using a self-administered questionnaire that was returned by mail in January and February 2005. The target population was 4735 community residents aged 20-75 years, who lived in the city of Koka, Shiga, Japan. A total of 2264 questionnaires were included in the analysis. A binominal logistic regression analysis showed that responses of 'trust' [odds ratio (OR): 2.09, 95% confidence interval (95% CI): 1.01-4.30] and 'strongly trust' (OR: 3.80, 95% CI: 1.55-9.31) for the national system were associated with not having anxiety regarding elderly care, compared with the reference category of feeling strongly distrust. However, trust in the municipal system showed no association with this anxiety. These results indicate the importance of developing strategies to increase a common trust in the national care services for the elderly to reduce the anxiety people feel regarding whether they will be able to receive elderly care when required.

Lifestyle-related chronic diseases such as cancer and cardiovascular disease are the greatest public health concerns. Evidence shows Japanese immigrants to a westernized environment have higher incidence of lifestyle-related diseases. However, little is known about lifestyle characteristics related to chronic diseases for Japanese in a westernized environment. This study is examining the gap in lifestyle by comparing the lifestyle prevalence for Japanese in the US with the Japanese National Data (the National Health and Nutrition Survey in Japan, J-NHANS) as well as the Japan National Health Promotion in the twenty-first Century (HJ21) goals. Japanese adults were surveyed in Pittsburgh, USA, regarding their lifestyle (e.g., diet, exercise, smoking, stress, alcohol, and oral hygiene). The prevalence was compared with J-NHANS and HJ21 goals. Ninety-three responded (response rate; 97.9%). Japanese men (n = 38) and women (n = 55) in Pittsburgh smoke less than Japanese in Japan (P < 0.001 for both genders). Japanese in Pittsburgh perform less physical activity in daily life and have lower prevalence of walking more than 1 h per day (P < 0.001 for both genders). Japanese women in Pittsburgh have significantly higher prevalence of stress than in Japan (P = 0.004). Japanese men in Pittsburgh do not reach HJ21 goal in weight management, BMI, use of medicine or alcohol to sleep, and sleep quality. Japanese women in Pittsburgh do not reach HJ21 goal in weight management and sleep quality. In conclusion, healthy lifestyle promotion including exercise and physical activity intervention for Japanese living in a westernized environment is warranted.

Alcoholic ketosis and ketoacidosis are metabolic abnormalities often diagnosed in alcoholics in emergency departments. We attempted to identify determinants or factors associated with alcoholic ketosis. The subjects of this cross-sectional survey were 1588 Japanese alcoholic men (≥40 years) who came to an addiction center within 14 days of their last drink. The results of the dipstick urinalyses revealed a prevalence of ketosis of 34.0% (±, 21.5%; +, 8.9%; and 2+/3+; 3.6%) in the alcoholics. Higher urine ketone levels were associated with higher serum total bilirubin, aspartate transaminase (AST), alanine transaminase and gamma-glutamyl transpeptidase levels. A multivariate analysis by the proportional odds model showed that the odds ratio (95% confidence interval) for an increase in ketosis by one category was 0.94 (0.84-1.06) per 10-year increase in age, 0.93 (0.89-0.97) per 1-day increase in interval since the last drink, 1.78 (1.41-2.26) in the presence of slow-metabolizing alcohol dehydrogenase-1B (ADH1B*1/*1), 1.61 (1.10-2.36) and 1.30 (1.03-1.65) when the beverage of choice was whiskey and shochu, respectively (distilled no-carbohydrate beverages vs. the other beverages), 2.05 (1.27-3.32) in the presence of hypoglycemia <80 mg/dl, 0.91 (0.88-0.94) per 1-kg/m(2) increase in body mass index (BMI), 1.09 (1.00-1.18) per +10 cigarettes smoked, and 2.78 (2.05-3.75) when the serum total bilirubin level was ≥2.0 mg/dl, and 1.97 (1.47-2.66) when the serum AST level was ≥200 IU/l. Ketosis was a very common complication and frequently accompanied by alcoholic liver injury in our Japanese male alcoholic population, in which ADH1B*1/*1 genotype, consumption of whiskey or shochu, hypoglycemia, lower BMI and smoking were significant determinants of the development of ketosis. © The Author 2014.

To investigate the association between nutritional evaluation indices (body mass index, albumin, and weight loss) and sarcopenia severity among community-dwelling elderly people in Japan. The subjects consisted of 758 community-dwelling elderly people ≥65 years of age, categorized into two groups by based on Operation of long life medical care system (medical care system for elderly in the latter stage of life), the cut-off value for age used was 75. The outcome measures were basic characteristics, anthropometric measures, physical function, and blood biochemistry (five assessments). The appendicular skeletal muscle mass was calculated via a bioelectrical impedance analysis. The subjects were categorized into three groups by the body mass index (BMI) [BMI 3 group]. The cut-off value for albumin used was 3.8 g/dL [A1b 2 group]. Weight loss was assessed using item 11 on the Kihon check list: "Have you experienced more than 2-3 kg weight loss over the past 6 months? Yes=1, No=0." [weight loss 2 group]. Sarcopenia was defined based on the European Working Group on Sarcopenia in Older People definition, using the Asian Working Group for Sarcopenia cut-off values. All subjects were then categorized into four groups based on their sarcopenia status: non-sarcopenic (non-), pre-sarcopenic (pre-), sarcopenic (sarco-), or severely sarcopenic (severe-) [sarco4 group]. The prevalence of sarcopenia and severe sarcopenia in men was 5.6% (n=18) and 1.2% (n=4), respectively, and in women was 7.8% (n=34) and 1.6% (n=7), respectively. The analysis showed that, among the people (>75 years of age) with normal BMI (18.5-25.0), 10.4%-15.6% were in the Sarco group. Further, among women over 75 years of age with BMI >25.0, 5.7% (n=2) were in the Sarco group. There was a significant association between weight loss and sarcopenia severity in older men. No significant association between albumin levels and sarcopenia severity was observed. 80.0% of weight-loss was presented in above BMI 18

The supplementation with vitamin D and calcium has been recommended for elderly, specifically those with increased risk of fractures older than 65 years. This study aims to assess the cost-effectiveness of vitamin D and calcium supplementation in elderly women and men with osteoporosis and therefore to assess if this recommendation is justified in terms of cost-effectiveness. A validated model for economic evaluations in osteoporosis was used to estimate the cost per quality-adjusted life-year (QALY) gained of vitamin D/calcium supplementation compared with no treatment. The model was populated with cost and epidemiological data from a Belgian health-care perspective. Analyses were conducted in women and men with a diagnosis of osteoporosis (i.e. bone mineral density T-score ≤-2.5). A literature search was conducted to describe the efficacy of vitamin D and calcium in terms of fracture risk reduction. The cost per QALY gained of vitamin D/calcium supplementation was estimated at €40 578 and €23 477 in women and men aged 60 years, respectively. These values decreased to €7912 and €10 250 at the age of 70 years and vitamin D and calcium supplementation was cost-saving at the age of 80 years, meaning that treatment cost was less than the costs of treating osteoporotic fractures of the no-treatment group. This study suggests that vitamin D and calcium supplementation is cost-effective for women and men with osteoporosis aged over 60 years. From an economic perspective, vitamin D and calcium should therefore be administrated in these populations including those also taking other osteoporotic treatments. © The Author 2014.

Few studies have examined Japanese with regard to the achievement rates for target blood pressure levels, or the relationship between these rates and healthy lifestyle characteristics in patients with hypertension as defined by the newly established hypertension management guidelines (JSH2014). The aim of this study was to elucidate achievement rates and examine healthy lifestyle characteristics associated with achievement status among Japanese. This cross-sectional study, conducted in January-December 2012, examined blood pressure control and healthy lifestyle characteristics in 8,001 Japanese workers with hypertension (mean age, 57.0 years; 78.8% were men) who participated in a workplace health checkup. Data were collected from workplace medical checkup records and participants' self-administered questionnaires. We divided into 5 groups [G1; young, middle-aged, and early-phase elderly patients (65-74 years old) without diabetes mellitus or chronic kidney disease (CKD) (<140/90 mmHg), G2; late-phase elderly patients (≥75 years old) without diabetes mellitus or CKD (<150/90 mmHg), G3; diabetic patients (<130/80 mmHg), G4; patients with CKD (<130/80 mmHg), and G5; patients with cerebrovascular and/or coronary artery diseases (<140/90 mmHg)] according to JSH2014. And then, achievement rates were calculated in each group. Multivariate analysis identified healthy lifestyle characteristics associated with "therapeutic failure" of target blood pressure. Target blood pressures were achieved by 60.2% of young, middle-aged, and early-phase elderly patients (G1), 71.4% of late-phase elderly patients (G2), 30.5% of diabetic patients (G3), 33.4% of those with chronic kidney disease (G4), and 66.0% of those with cerebrovascular and/or coronary artery diseases (G5). A body mass index of 18.5-24.9 and non-daily alcohol consumption were protective factors, and adequate sleep was found to contribute to therapeutic success. We found low achievement rates for treatment goals among

Only a few population-based prospective studies have examined the association between alcohol consumption and abdominal aortic aneurysm, and the results are inconsistent. Moreover, no evidence exists for aortic dissection. We examined the effect of alcohol consumption on risk of mortality from aortic diseases. A total of 34,720 men from the Japan Collaborative Cohort study, aged 40-79 years, without history of cardiovascular disease and cancer at baseline 1988 and 1990 were followed up until the end of 2009 for their mortality and its underlying cause. Hazard ratios of mortality from aortic diseases were estimated according to alcohol consumption categories of never-drinkers, ex-drinkers, regular drinkers of ≤30 g, and >30 g ethanol per day. During the median 17.9-year follow-up period, 45 men died of aortic dissection and 41 men died of abdominal aortic aneurysm. Light to moderate drinkers of ≤30 g ethanol per day had lower risk of mortality from total aortic disease and aortic dissection compared to never-drinkers. The respective multivariable hazard ratios (95% confidence intervals) were 0.46 (0.28-0.76) for total aortic disease and 0.16 (0.05-0.50) for aortic dissection. Heavy drinkers of >30 g ethanol per day did not have reduced risk of mortality from total aortic disease, albeit had risk variation between aortic dissection and abdominal aortic aneurysm. Light to moderate alcohol consumption was associated with reduced mortality from aortic disease among Japanese men. Copyright © 2017. Published by Elsevier B.V.

Body weight change (gain or loss) and fluctuation have been associated with an increased risk of cardiovascular disease and death from all causes. In this study, to determinate the effects of weight change and fluctuation on coronary risk factors (CRF) in Japanese, 242 middle-aged men aged 35-58 years, white-collar workers in Tokyo, were followed for 6-years (1990-1995). Height body weight, systolic (SBP) and diastolic (DBP) blood pressure, total cholesterol (TC), high (HDL-C) and low (LDL-C) density lipoprotein cholesterol, triglyceride (TG), and fasting plasma glucose (FPG) were measured each year at an annual health check-up. Over the 6 time periods, body mass index (BMI: body weight (kg) divided by the squared of the height (m)) mean was calculated as a value for the variable BMI level of each subject (BMImean). Direction and magnitude of the change in a subject's BMI was determined by regression of 6 BMI value on time for each individual slope (BMIslope). BMI fluctuation was defined as the root mean square error (BMIRMSE) of a regression line fitted to each individual's BMI value over time. The slopes of the 7 CRF were calculated using each regression equation over time. The CRF slopes were most strongly related to the baseline value of each risk factor, BMImean and BMIslope. BMIRMSE was not related to CRF slopes. In this population, BMI fluctuation had little impact on CRF compared with BMIslope and BMImean. This study results indicate that weight gain and loss has a much greater effect on CRF than does weight fluctuation in Japanese middle-aged men.

Although factors associated with falls might differ between men and women, no large-scale studies were conducted to examine the sex difference of risk factors for falls in Japanese elderly. The purpose of this study was to examine fall risk factors and sex differences among community-dwelling elderly individuals using a complete survey of the geriatric population in Kameoka city. A self-administered questionnaire survey was conducted with 18,231 community-dwelling elderly individuals aged 65 years or over in Kameoka city, Kyoto Prefecture, between July and August 2011, excluding people who were publicly certified with a long-term care need of grade 3 or higher. The questionnaire was individually distributed and collected via mail. Out of 12,159 responders (recovery rate of 72.2%), we analyzed the data of 12,054 elderly individuals who were not certified as having long-term care needs. The questionnaire was composed of basic attributes, a simple screening test for fall risk, the Kihon Check List with 25 items, and the Tokyo Metropolitan Institute of Gerontology (TMIG) index of competence with 13 items. These items were grouped into nine factors: motor function, malnutrition, oral function, houseboundness, forgetfulness, depression, Instrumental Activity of Daily Living (IADL), intellectual activities, and social role. Of all the respondents, 20.8% experienced falls within the last year, and 26.6% were classified as having high fall risk. Fall risk increased with age in both sexes, and risk in all age groups was higher for women than for men. All factors were significantly associated with fall risk in both sexes. After controlling for these factors, a significant relationship was found between fall risk and motor function, malnutrition, oral function, forgetfulness, depression, and IADL in men and motor function, oral function, forgetfulness, depression, and IADL in women. The deterioration of motor function was associated with three-times-higher risk than non

The aim of the present study was to verify if there is sex difference in the associations among handgrip strength, peak expiratory flow (PEF) and timed up and go (TUG) test results. The sample included 288 consecutive elderly men (n=93) and women (n=195). Functional capacity was measured using the TUG test, and muscle strength was measured based on handgrip. Moreover, as a measure of current health status, PEF was evaluated. Linear regression procedures were performed to analyze the relationships between handgrip and both PEF and TUG test results, with adjustment for confounders, and to identify the possible mediating role of PEF in the association between handgrip strength and TUG test results. In men, handgrip strength was associated with both PEF and TUG performance (p<0.01). After adjustment for PEF, the relationship between handgrip strength and TUG performance remained significant. In women, handgrip strength was also associated with both PEF and TUG performance (p<0.01). However, after adjustment for PEF, the relationship between handgrip strength and TUG performance was no longer significant. Mobility in the elderly is sex dependent. In particular, PEF mediates the relationship between handgrip strength and TUG performance in women, but not in men.

As 90% of fractures are caused by falls, and as fractures are more common in elderly women than in elderly men, a better understanding of potential sex differences in fall rates and underlying mechanisms is needed. The purpose of this study was to determine whether women are more prone than men to falling, and to evaluate whether the risk of falling is associated with variations in gait patterns. The cohort for this prospective observational study consisted of 1390 community-dwelling men and women aged 70 years, examined in a health survey between July 2012 and November 2014. Gait patterns were measured using a computerized walkway system during normal-speed, fast-speed, and dual-task trials. Triaxial accelerometers were used to collect objective data on physical activity, and self-reported fall data were collected by telephone 6 and 12 months after examination. Incident low-energy falls were defined as unexpected events in which participants came to rest on the ground. During the follow-up period, 148 study participants (88 women, 60 men; P = .01) reported falls. After adjusting for multiple confounders, including objective measures of physical activity, socioeconomic factors, cardiovascular disease, and cognitive function, the odds ratio for falling in women was 1.49 (95% confidence interval [CI] 1.02-2.19). Variations in gait pattern were significantly (20%-40%) increased in fallers compared with nonfallers during the dual-task trial for step width, step length, stride length, step time, stance time, stride velocity, and single support time (all P < .05). Furthermore, women showed 15% to 35% increased variability in all of these gait parameters during the dual-task trial compared with men (all P < .01). In the present cohort, 70-year-old women were at greater risk of falls compared with their male counterparts. This increased risk was associated with increased variation in gait pattern during dual-task activities, and may contribute to women's greater

Effects of high altitude on arterial stiffness and neuro-cardio-pulmonary function were studied. Blood pressure (BP) and heart rate (HR) were measured in a sitting position on resting Ladakhis, living at an altitude of 3250-4647 m (Phey village, 3250 m: 17 men and 55 women; Chumathang village, 4193 m: 29 men and 47 women; Sumdo village, 4540 m: 38 men and 57 women; and Korzok village, 4647 m: 84 men and 70 women). The neuro-cardio-pulmonary function, including the Kohs block design test, the Up and Go, the Functional Reach and the Button tests, was examined in 40 elderly subjects (19 men and 21 women, mean age: 74.7 +/- 3.3 years) in Leh, Ladakh (altitude: 3524 m), for comparison with 324 elderly citizens (97 men and 227 women, mean age: 80.7 +/- 4.7 years) of Tosa, Japan (altitude: 250 m). Cardio-Ankle Vascular Index (CAVI) was measured as the heart-ankle pulse wave velocity (PWV) in these subjects using a VaSera CAVI instrument (Fukuda Denshi, Tokyo). SpO(2) decreased while Hb and diastolic BP increased with increasing altitude. At higher altitude, residents were younger and leaner. Women in Leh vs. Tosa had a poorer cognitive function, estimated by the Kohs block design test (3.7 +/- 3.6 vs. 16.4 +/- 9.6 points, P < 0.0001) and poorer ADL functions (Functional Reach: 13.7 +/- 7.0 cm vs. 25.3 +/- 8.7 cm, P < 0.0001; Button test: 22.5 +/- 4.8 vs. 14.8 +/- 5.7 s, P < 0.0001). Time estimation was shorter at high altitude (60-s estimation with counting: 41.1% shorter in men and 23.0% shorter in women). A higher voltage of the QRS complex was observed in the ECG of Leh residents, but two times measurement of CAVI showed no statistically significant differences between Leh and Tosa (two times of CAVI measures; 9.49 vs. 10.01 m/s and 9.41 vs. 10.05 m/s, respectively), suggesting that most residents succeed to adapt sufficiently to the high-altitude environment. However, correlation of CAVI with age shows several cases who show an extreme increase in CAVI. Thus, for the

Non-fasting triglycerides were reported to have a greater impact on risk of ischemic cardiovascular events than fasting triglycerides. However, evidence from Asia, where the prevalence of dyslipidemia is generally lower, has been limited. We used 1975-1986 baseline surveys to investigate cohort data of 10,659 (4264 men and 6395 women) residents aged 40-69 years, initially free from ischemic heart disease and stroke, in four Japanese communities. Serum triglyceride concentrations at baseline were obtained for 2424 fasting (≥8 h after meal) and 8235 non-fasting (<8 h after meal) participants. During the 22-year follow-up, 284 (165 men and 119 women) developed ischemic heart disease and 666 (349 men and 317 women) ischemic stroke. After adjustment for age, sex and known cardiovascular risk factors, multivariable hazard ratios (95%CI) of ischemic cardiovascular disease (ischemic heart disease and ischemic stroke) for the highest versus lowest quartiles of triglycerides were 1.71 (1.14-2.59), P for trend = 0.013, for fasting participants and 1.60 (1.25-2.05), P for trend <0.001, for non-fasting participants. The positive associations did not differ between fasting and non-fasting men, while they were strong for non-fasting women. They were stronger for ischemic heart disease than for ischemic stroke. After further adjustment for HDL-cholesterol, these associations were slightly attenuated, but remained statistically significant. Non-fasting as well as fasting triglycerides are predictive of risk of ischemic cardiovascular disease for Japanese men, as are non-fasting triglycerides for women. Copyright © 2014.

Maruyama, Yoshiaki

2009-11-01

Vascular and cardiac aging is rapidly progressing among the Japanese population. A close relation exists between the artery and cardiac performance (arterial-cardiac interaction), but the relationships between age and these parameters have not been well examined. The aim of this study was to elucidate the changes of arterial-cardiac interaction with aging, using pulse wave velocity (PWV) as an indicator of atherosclerosis. The subjects comprised 595 adult men (mean age, 58.8 +/- 12.2 years) without any history of cardiovascular disease. After correlating PWV, cardiac structure, cardiac function, and blood pressure to age, subjects were divided into five age groups to compare changes in these parameters. Pulse wave velocity exhibited a strong positive correlation with age (r = 0.461, P < 0.01) and increased significantly over 55 years old, and left atrial dimension, relative wall thickness, systolic blood pressure, and pulse pressure correlated positively with age and increased similarly. Left ventricular volume correlated negatively with age and decreased similarly. These parameters significantly correlated with PWV. Aortic diameter (AoD) positively and EA ratio (E/A) negatively exhibited a correlation with age and revealed earlier change before PWV increase. Aortic diameter increased significantly over 45 years old and stayed flat, but E/A decreased linearly from the early period. Diastolic blood pressure (DBP) increased in the early period and decreased over 75 years of age. Agerelated atherosclerotic close arterial-cardiac interaction exists between the vessels and cardiac performance, but AoD, E/A, and DBP change in early age independent of atherosclerosis.

We investigated the efficacy of desmopressin in elderly patients with nocturnal polyuria (NP) to evaluate its effects on sleep quality. Patients with NP (defined as the nighttime urine production >33% of total 24-hour urine volume determined from a frequency-volume chart) were recruited. Desmopressin (0.2 mg) was treated orally at bedtime for 12 weeks. The participants completed the Medical Outcomes Study (MOS) Sleep Scale. The mean patient age was 62.7 ± 13.0 (range 42-78 years). The mean symptom duration was 42.2 ± 39.7 months. The number of nocturia episodes (from 3.49 ± 1.83 to 2.03 ± 1.35, p = 0.01), nocturnal urine volume (p = 0.01), NP index (p = 0.01), and nocturia index (p = 0.01) decreased significantly after treatment with desmopressin. Among the MOS Sleep Scale categories, hours slept/night (p = 0.042), shortness of breath (p = 0.019), and adequacy of sleep (p = 0.001) changed significantly with a decrease in the number of nocturia episodes. Adverse events were mild. Desmopressin is an effective treatment for NP and improved sleep quality in elderly men. © 2016 S. Karger AG, Basel.

Exercise training guidelines for the elderly.

PubMed

Evans, W J

1999-01-01

The capacity of older men and women to adapt to increased levels of physical activity is preserved, even in the most elderly. Aerobic exercise results in improvements in functional capacity and reduced risk of developing Type II diabetes in the elderly. High-intensity resistance training (above 60% of the one repetition maximum) has been demonstrated to cause large increases in strength in the elderly. In addition, resistance training result in significant increases in muscle size in elderly men and women. Resistance training has also been shown to significantly increase energy requirements and insulin action of the elderly. We have recently demonstrated that resistance training has a positive effect on multiple risk factors for osteoporotic fracture in previously sedentary postmenopausal women. Because the sedentary lifestyle of a long-term care facility may exacerbate losses of muscle function, we have applied this same training program to frail, institutionalized elderly men and women. In a population of 100 nursing home residents, a randomly assigned high-intensity strength-training program resulted in significant gains in strength and functional status. In addition, spontaneous activity, measured by activity monitors, increased significantly in those participating in the exercise program whereas there was no change in the sedentary control group. Before the strength training intervention, the relationship of whole body potassium and leg strength was seen to be relatively weak (r2 = 0.29, P < 0.001), indicating that in the very old, muscle mass is an important but not the only determining factor of functional status. Thus, exercise may minimize or reverse the syndrome of physical frailty, which is so prevalent among the most elderly. Because of their low functional status and high incidence of chronic disease, there is no segment of the population that can benefit more from exercise than the elderly.

Disability and handicap among elderly Singaporeans.

Singapore's elderly population has been growing rapidly and is expected to constitute more than 25 percent of the total population by the year 2030. The ageing process brings with it a host of health problems. Here the question arises--Are the increasing years of life going to create a high proportion of sick and disabled elderly people, or a rich human resource of healthy senior citizens? Since more women are living longer than men, who would face a higher risk of disability and handicap? These questions are yet to be answered in Singapore. This paper seeks answers to these questions. The study is based on a sample survey of 1209 elderly Singaporeans living in Kampong Glam, Kreta Ayer and Bukit Merah parliamentary constituencies which have some of the highest proportions of the aged population. The results revealed that more than half of the aged had a disability and the rate of disability was significantly higher among the women as compared to the men. More than one-third of the elderly had a handicap and the rate of handicap among the women was twice as much as that among the men. Severity of handicap was directly correlated with age.

The effect of aspirin in primary prevention of stroke is controversial among clinical trials conducted in Western countries, and no data are available for Asian populations with a high risk of intracranial hemorrhage. The objective of this study was to evaluate the effect of aspirin on the risk of stroke and intracranial hemorrhage in the Japanese Primary Prevention Project (JPPP). A total of 14 464 patients (age, 60-85 years) with hypertension, dyslipidemia, and diabetes mellitus participated and were randomized into 2 treatment groups: 100 mg of aspirin or no aspirin. The median follow-up period was 5.02 years. The cumulative rate of fatal or nonfatal stroke was similar for the aspirin (2.068%; 95% confidence interval [CI], 1.750-2.443) and no aspirin (2.299%; 95% CI, 1.963-2.692) groups at 5 years; the estimated hazard ratio was 0.927 (95% CI, 0.741-1.160; P=0.509). Aspirin nonsignificantly reduced the risk of ischemic stroke or transient ischemic attack (hazard ratio, 0.783; 95% CI, 0.606-1.012; P=0.061) and nonsignificantly increased the risk of intracranial hemorrhage (hazard ratio, 1.463; 95% CI; 0.956-2.237; P=0.078). A Cox regression adjusted by the risk factors for all stroke, which were age >70 years, smoking, and diabetes mellitus, supported the above result. Aspirin did not show any net benefit for the primary prevention of stroke in elderly Japanese patients with risk factors for stroke, whereas age >70 years, smoking, and diabetes mellitus were risk factors for stroke regardless of aspirin treatment.

The 15D is a self-administered questionnaire for assessment of health-related quality of life, which contains 15 questions with 5 response options each. This study was conducted to evaluate the reliability and validity of the Japanese 15D. The subjects were 430 community-dwelling elderly people. Each item of the 15D was scored on a 5-point Likert scale, with level 1 being the best, score 1. Reliability was assessed by determination of the internal consistency and test-retest reliability. Criterion-based validity was assessed using the Japanese version of the Nottingham Health Profile (NHP) and Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG index). Acceptability was assessed by inquiring about the time required to complete the questionnaire and the burden felt in responding to it. The answers of 423 individuals who responded to all items were analyzed. The median time required to complete the questionnaire was 5.0 minutes, and the proportion of subjects who indicated that the questionnaire was easy to complete was 98.3%. The Cronbach's alpha coefficients for all 15 items in the 2 surveys were 0.793 and 0.792, respectively. The intraclass correlation coefficients for the 15 items ranged from 0.44 to 0.72. In the relationship between the 15D and the NHP, the correlation coefficients between the corresponding domains were higher than those between non-corresponding domains. The prevalence of disability in higher-level functional capacity was higher in the "level 2 to 5" group than in the "level 1" group. The Japanese version of the 15D showed sufficient internal consistency and moderate repeatability. Because of the short time required to complete the Japanese 15D and the significant relationships between the scores on the 15D and the NHP, and between the 15D and higher-level functional capacity, the acceptability and validity of the Japanese 15D were considered to be sufficient.

Objective: The objective of this study was to verify the recognition of dangers and obstacles within a house in the elderly when walking based on analyses of gaze point fixation. Materials and Methods: The rate of recognizing indoor dangers was compared among 30 elderly, 14 middle-aged and 11 young individuals using the Eye Mark Recorder. Results: 1) All of the elderly, middle-aged and young individuals showed a high recognition rate of 100% or near 100% when ascending outdoor steps but a low rate of recognizing obstacles placed on the steps. They showed a recognition rate of about 60% when descending steps from residential premises to the street. The rate of recognizing middle steps in the elderly was significantly lower than that in younger and middle-aged individuals. Regarding recognition indoors, when ascending stairs, all of the elderly, middle-aged and young individuals showed a high recognition rate of nearly 100%. When descending stairs, they showed a recognition rate of 70-90%. However, although the recognition rate in the elderly was lower than in younger and middle-aged individuals, no significant difference was observed. 2) When moving indoors, all of the elderly, middle-aged and young individuals showed a recognition rate of 70%-80%. The recognition rate was high regarding obstacles such as floors, televisions and chests of drawers but low for obstacles in the bathroom and steps on the path. The rate of recognizing steps of doorsills forming the division between a Japanese-style room and corridor as well as obstacles in a Japanese-style room was low, and the rate in the elderly was low, being 40% or less. Conclusion: The rate of recognizing steps of doorsills as well as obstacles in a Japanese-style room was lower in the elderly in comparison with middle-aged or young individuals. PMID:25648876

As the number of dual-earner couples in Japan has increased, work-life balance has become important. This study aimed to examine the factors that contribute to work-family conflict. The participants included 3,594 (2,332 men and 1,262 women) civil servants aged 20-59 working for local government on the west coast of Japan. Logistic regression analysis was used to evaluate whether work, family, or lifestyle characteristics were associated with work-family conflict. For men, family-to-work conflict was associated with being elderly, having low-grade employment, working long hours, raising children, and sleeping shorter hours. For women, being married and raising children were strong determinants of family-to-work conflict, and being middle-aged, working long hours, and sleeping shorter hours were also associated with this type of conflict. Regarding work-to-family conflict, working long hours was the strongest determinant of conflict in both sexes. In men, being elderly, living with family, eating dinner late, and sleeping shorter hours were also associated with work-to-family conflict. In women, having high-grade employment, being married, raising children, and eating dinner late were associated with work-to-family conflict. This study showed that working long hours was the primary determinant of work-to-family conflict in both sexes and that being married and raising children were strong factors of family-to-work conflict in women only. Sex differences may reflect divergence of the social and domestic roles of men and women in Japanese society. To improve the work-life balance, general and sex-specific health policies may be required.

Although a foot care program for long-term care prevention has been launched in Japan, few studies have examined its effectiveness. The purpose of the present investigation was to examine the association of foot problems with fall experience and fear of falling among Japanese community-dwelling elderly people. The participants were 10,581 community-dwelling elderly people (75.2 +/- 5.6 years) and the study design was cross-sectional using a questionnaire. Self-reported tinea pedis, skin problems (inflammation, swelling, or discoloration), nail problems (thickening or deformities), impairment (in function or blood flow), regular foot care, and wearing of appropriate shoes were selected as parameters of foot problems and their care. Logistic regression analysis was conducted to examine whether these were related to fall experience (in the past 1 year) and fear of falling adjusted for age, the Tokyo Metropolitan institute of gerontology index of competence, medical conditions, and lower limb functions. Forty-six percents of males and 39.0% of females reported at least one foot problem. After adjusting for covariates, tinea pedis (male: adjusted odds ratio = 1.37[95% confidence interval= 1.15-1.63], female: 1.29[1.08-1.53]), skin problems (male: 1.66[1.32-2.101, female: 1.37[1.13-1.66]), nail problems (male: 1.72[1.45-2.051, female: 1.48[1.26-1.74]), and functional impairment (male: 2.42[1.91-3.05], female: 1.66[1.36-2.04]) were significantly associated with fall experience. Also, each problem was negatively associated with fear of falling (tinea pedis[male: 1.37 [1.15-1.62], female: 1.25[1.07-1.47

The decline in BMI among Japanese women after World War II.

2015-07-01

The body mass index (BMI) of the Japanese is significantly lower than is found in other high-income countries. Moreover, the average BMI of Japanese women is lower than that of Japanese men, and the age-specific BMI of Japanese women has decreased over time. The average BMI of Japanese women at age 25 decreased from 21.8 in 1948 to 20.4 in 2010 whereas that of men increased from 21.4 to 22.3 over the same period. We examine the long-term BMI trend in Japan by combining several historical data sources spanning eleven decades, from 1901 to 2012, to determine not only when but also how the BMI decline among women began: whether its inception was period-specific or cohort-specific. Our nonparametric regression analysis generated five findings. First, the BMI of Japanese women peaked with the 1930s birth cohort. This means that the trend is cohort-specific. Second, the BMI of men outpaced that of women in the next cohort. Third, the BMI of Japanese children, boys and girls alike, increased steadily throughout the 20th century. Fourth, the gender difference in the BMI trend is due to a gender difference in the weight trend, not the height trend. Fifth, these BMI trends are observed in urban and rural populations alike. We conclude that the BMI decline among Japanese women began with those who were in their late teens shortly after World War II. Copyright © 2015 Elsevier B.V. All rights reserved.

In our previous studies, we found both gender differences among care recipients and predictors that influenced outcomes after discharge from a ward for demented elderly. Here, we investigate predictors that influence the length of stay for each sex. We studied the data of 390 patients with dementia who were hospitalized in a ward for demented elderly between 1 April 2000 and 31 March 2008, and treated until 31 March 2009. The patients were divided into groups classified by gender. We analyzed the gender differences of characteristics and evaluated the predictors that influenced the length of stay in the ward for demented elderly using Cox's proportional hazards model. A model using the initial scores of the Revised Hasegawa Dementia Scale (HDS-R), Assessment Scale for Symptoms of Dementia (ASSD) and Nishimura's activity of daily living scale (N-ADL), which were examined on admission, was named Model 1. In Model 1, we checked the effect of each patient's characteristics, except for complications and destinations, on their length of stay. Model 2 used the final scores of HDS-R, ASSD and N-ADL including complications and destinations. There was a clear gender difference in the length of stay. The length of stay of women was longer than that of men. It was difficult to predict the length of stay in Model 1. Age was the only predictor in women and no predictor was identified in men. In Model 2, complications and the final HDS-R and N-ADL scores were predictors of the length of stay in men. Age, complications and destinations were predictors of the length of stay in women. It was observed that there were gender differences among predictors of the length of stay. However, it was difficult to predict the length of stay on admission. Retrospectively, the length of stay was determined by physical and psychological conditions, not by the social variables in men. In women, it was supposed that the caregiver's wish to give care at home reduced the length of stay. Besides

The clinical significance of coronary artery calcification (CAC) is not fully determined in general East Asian populations where background coronary heart disease (CHD) is less common than in USA/Western countries. We cross-sectionally assessed the association between CAC and estimated CHD risk as well as each major risk factor in general Japanese men. Participants were 996 randomly selected Japanese men aged 40-79 y, free of stroke, myocardial infarction, or revascularization. We examined an independent relationship between each risk factor used in prediction models and CAC score ≥100 by logistic regression. We then divided the participants into quintiles of estimated CHD risk per prediction model to calculate odds ratio of having CAC score ≥100. Receiver operating characteristic curve and c-index were used to examine discriminative ability of prevalent CAC for each prediction model. Age, smoking status, and systolic blood pressure were significantly associated with CAC score ≥100 in the multivariable analysis. The odds of having CAC score ≥100 were higher for those in higher quintiles in all prediction models (p-values for trend across quintiles ＜0.0001 for all models). All prediction models showed fair and similar discriminative abilities to detect CAC score ≥100, with similar c-statistics (around 0.70). In a community-based sample of Japanese men free of CHD and stroke, CAC score ≥100 was significantly associated with higher estimated CHD risk by prediction models. This finding supports the potential utility of CAC as a biomarker for CHD in a general Japanese male population.

Equol, a metabolite of the dietary isoflavone daidzein, is produced by the action of gut bacteria in some individuals who are termed as equol-producers. It is proposed to have stronger atheroprotective properties than dietary isoflavones. We examined a cross-sectional association of dietary isoflavones and equol-producer status with coronary artery calcification (CAC), a biomarker of coronary atherosclerosis, among men in Japan. A population-based sample of 272 Japanese men aged 40-49 years recruited from 2004 to 2007 was examined for serum isoflavones, serum equol, CAC and other factors. Equol-producers were classified as individuals having a serum level of equol >83 nm. The presence of CAC was defined as a coronary Ca score ≥10 Agatston units. The associations of dietary isoflavones and equol-producers with CAC were analysed using multiple logistic regression. The median of dietary isoflavones, equol and CAC were 512·7 (interquartile range (IQR) 194·1, 1170·0), 9·1 (IQR 0·10, 33·1) and 0·0 (IQR 0·0, 1·0) nm, respectively. Prevalence of CAC and equol-producers was 9·6 and 16·0 %, respectively. Dietary isoflavones were not significantly associated with CAC. After multivariable adjustment, the OR for the presence of CAC in equol-producers compared with equol non-producers was 0·10 (95 % CI 0·01, 0·90, P<0·04). Equol-producers had significantly lower CAC than equol non-producers, but there was no significant association between dietary isoflavones and CAC, suggesting that equol may be a key factor for atheroprotective properties of isoflavones in Japanese men. This finding must be confirmed in larger studies or clinical trials of equol that is now available as a dietary supplement.

We conducted analyses of repeated-measures data to examine whether pressure wave reflection acts additively or synergistically with arterial stiffness in the pathogenesis of hypertension. In 3172 middle-aged (42±9 years) healthy Japanese men without hypertension at the study baseline, systolic and diastolic blood pressures, brachial-ankle pulse wave velocity, and radial augmentation index were measured annually during a 9-year study period. Of these, 474 participants (15%) developed hypertension by the end of the study period. Binary logistic regression analysis demonstrated significant individual odds ratios for both baseline brachial-ankle pulse wave velocity and radial augmentation index for the development of hypertension. The rate of onset of hypertension during the study period was highest in the participant group with high values for both brachial-ankle pulse wave velocity and radial augmentation index at study baseline (262 of 965 participants: 27%). The generalized estimating equation analysis revealed that both radial augmentation index (estimate=0.06, SE=0.03, P =0.05) and brachial-ankle pulse wave velocity (estimate=0.07×10 -1 , SE=0.02×10 -1 , P <0.01) showed significant longitudinal association with new onset of hypertension, with no significant interaction. In Japanese men, abnormal wave reflection and increased arterial stiffness may be additively associated with the risk of new onset of hypertension. Abnormal wave reflection and elevated central blood pressure may be longitudinally associated with increase in arterial stiffness, and this longitudinal association may be a mechanism underlying the additive effect of these 2 variables on the risk of new onset of hypertension. © 2018 The Authors.

Effects of high altitude on arterial stiffness and neuro-cardio-pulmonary function were studied. Blood pressure (BP) and heart rate (HR) were measured in a sitting position on resting Ladakhis, living at an altitude of 3250–4647 m (Phey village, 3250 m: 17 men and 55 women; Chumathang village, 4193 m: 29 men and 47 women; Sumdo village, 4540 m: 38 men and 57 women; and Korzok village, 4647 m: 84 men and 70 women). The neuro-cardio-pulmonary function, including the Kohs block design test, the Up and Go, the Functional Reach and the Button tests, was examined in 40 elderly subjects (19 men and 21 women, mean age: 74.7 ± 3.3 years) in Leh, Ladakh (altitude: 3524 m), for comparison with 324 elderly citizens (97 men and 227 women, mean age: 80.7 ± 4.7 years) of Tosa, Japan (altitude: 250 m). Cardio-Ankle Vascular Index (CAVI) was measured as the heart-ankle pulse wave velocity (PWV) in these subjects using a VaSera CAVI instrument (Fukuda Denshi, Tokyo). SpO2 decreased while Hb and diastolic BP increased with increasing altitude. At higher altitude, residents were younger and leaner. Women in Leh vs. Tosa had a poorer cognitive function, estimated by the Kohs block design test (3.7 ± 3.6 vs. 16.4 ± 9.6 points, P < 0.0001) and poorer ADL functions (Functional Reach: 13.7 ± 7.0 cm vs. 25.3 ± 8.7 cm, P < 0.0001; Button test: 22.5 ± 4.8 vs. 14.8 ± 5.7 s, P < 0.0001). Time estimation was shorter at high altitude (60-s estimation with counting: 41.1% shorter in men and 23.0% shorter in women). A higher voltage of the QRS complex was observed in the ECG of Leh residents, but two times measurement of CAVI showed no statistically significant differences between Leh and Tosa (two times of CAVI measures; 9.49 vs. 10.01 rn/s and 9.41 vs. 10.05 m/s, respectively), suggesting that most residents succeed to adapt sufficiently to the high-altitude environment. However, correlation of CAVI with age shows several cases who show an extreme increase in CAVI. Thus, for the

Data on the association between vitamin D status and osteoporotic fracture in Asians are sparse. We conducted a 6-year cohort study of 773 community-dwelling elderly Japanese women and found that serum 25-hydroxyvitamin D (25(OH)D) ≥ 71 nmol/L was associated with a reduced risk of osteoporotic limb and vertebral fractures. Data on the association between vitamin D status and osteoporotic fracture in Asians are sparse. This study aimed to clarify the association between vitamin D and other markers of nutritional status with the incidence of fracture in elderly Japanese women. We conducted a cohort study with a 6-year follow-up of 773 community-dwelling women aged 69 years and older. The 6-year follow-up ended in 2009. We assessed serum 25-hydroxyvitamin D, undercarboxylated osteocalcin (an index of vitamin K status), and calcium intake. The primary outcome was incident limb and vertebral fractures. Covariates were forearm bone mineral density (BMD), age, body mass index, osteoporosis treatment, and physical activity. The mean serum 25(OH)D concentration was 60.0 nmol/L. Thirty-seven limb fractures and 14 vertebral fractures occurred in 4,392 person-years. Lower forearm BMD was significantly associated with increased incident fracture (P = 0.0242). The adjusted hazard ratios (HR) of fracture for the first quartile (<47.7 nmol/L) and the third quartile (59.2-70.9 nmol/L) of serum 25(OH)D, compared to the fourth quartile (≥71.0 nmol/L), were 2.82 (95% confidence interval (CI), 1.09-7.34) and 2.82 (95%CI, 1.09-7.27), respectively. The pooled adjusted HR was 0.42 (95%CI, 0.18-0.99) when the incidence in the fourth quartile (≥71.0 nmol/L) was compared to the other three quartiles combined (<71.0 nmol/L). Vitamin K status and calcium intake were not associated with incident fracture. Sufficient vitamin D status, i.e., serum 25(OH)D ≥ 71 nmol/L, is associated with low limb and vertebral fracture risk in community-dwelling elderly women.

This study aimed at determining the factors associated with sarcopenia, defined as low muscle mass and strength and low physical performance, in community-dwelling elderly subjects in Japan. The subjects included 1,074 elderly, community-dwelling Japanese people aged 65 years or older. We measured appendicular muscle mass (AMM) by bioelectrical impedance analysis, grip strength, and usual walking speed. A low muscle mass was defined by the AMM index (AMI, weight [kg]/height [m(2)] as >2 standard deviations below the mean AMI for normal young subjects. The lowest quartile for grip strength and usual walking speed were classified as low muscle strength and low physical performance, respectively. "Sarcopenia" was characterized by a low muscle mass, combined with either a low muscle strength or low physical performance. Subjects without low muscle mass or strength and low physical performance were classified as "normal." Subjects were classified as being "intermediate" if they were neither "sarcopenic" nor "normal." Items in the questionnaire included residential status, past medical history, admission during the past year, smoking and drinking habits, leisure-time physical activity, health status, depression, masticatory ability, and dietary variety score. Sarcopenia was identified in 13.7% of men and 15.5% of women. Among men, a large proportion of subjects with sarcopenia had poor masticatory ability and a low dietary variety score compared with normal or intermediate subjects. Among women, a large proportion of the subjects with sarcopenia lived alone, had poor exercise habits, considered themselves to be unhealthy, and had poor masticatory ability compared with normal or intermediate subjects. A multiple logistic regression analysis showed that age and dietary variety in men and age and masticatory ability in women were associated with sarcopenia. The present study carried out in Japan showed that sarcopenia, assessed by muscle mass, muscle strength, and physical

Background Habitual coffee consumption has been reported to lower blood pressure in the Japanese population. The NADH dehydrogenase subunit-2 237 leucine/methionine (ND2-237 Leu/Met) polymorphism is associated with longevity and modifies the effects of alcohol consumption on blood pressure in the Japanese population. The objective of this study was to determine whether this polymorphism also modifies the effects of coffee consumption on blood pressure or the risk of hypertension in middle-aged Japanese men. Methods A total of 398 men (mean age ± standard deviation, 53.8 ± 7.8 years) were selected from among individuals visiting the hospital for regular medical check-ups. Hypertension was defined as a systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or antihypertensive drug treatment. Polymerase chain reaction-restriction fragment length polymorphism using the restriction enzyme AluI was performed to determine ND2-237 Leu/Met genotype. Results In subjects with ND2-237Leu, coffee consumption was significantly and negatively associated with diastolic blood pressure (P = 0.007). The odds ratio (OR) for hypertension was significantly lower in subjects with ND2-237Leu who consumed 2 or 3 cups of coffee per day than in those who consumed less than 1 cup of coffee per day (OR, 0.517; 95% confidence interval [CI], 0.276 to 0.968; P = 0.039). After adjustment, the OR remained significant (OR = 0.399; 95% CI, 0.184 to 0.869; P = 0.020). Moreover, after adjustment, the OR was significantly lower in subjects with ND2-237Leu who consumed more than 4 cups of coffee per day than in those who consumed less than 1 cup of coffee per day (OR, 0.246; 95% CI, 0.062 to 0.975; P = 0.046). However, the association between ND2-237Met genotype and hypertension did not depend on coffee consumption. Conclusions The present results suggest that the ND2-237 Leu/Met polymorphism modulates the effects of coffee consumption on hypertension risk in middle-aged Japanese

With ageing, there is a greater risk of dehydration. This study investigated the diuretic effect of alcoholic beverages varying in alcohol concentration in elderly men. Three alcoholic beverages (beer (AB), wine (AW), and spirits (S)) and their non-alcoholic counterparts (non-alcoholic beer (NAB), non-alcoholic wine (NAW), and water (W)) were tested in a diet-controlled randomized crossover trial. For the alcoholic beverages, alcohol intake equaled a moderate amount of 30 g. An equal volume of beverage was given for the non-alcoholic counterpart. After consumption, the urine output was collected every hour for 4 h and the total 24 h urine output was measured. AW and S resulted in a higher cumulative urine output compared to NAW and W during the first 4 h (effect size: 0.25 mL p < 0.003, effect size: 0.18 mL, p < 0.001, respectively), but not after the 24h urine collection ( p > 0.40, p > 0.10). AB and NAB did not differ at any time point (effect size: -0.02 mL p > 0.70). For urine osmolality, and the sodium and potassium concentration, the findings were in line. In conclusion, only moderate amounts of stronger alcoholic beverages, such as wine and spirits, resulted in a short and small diuretic effect in elderly men.

Physical activity is suggested to play a key role in the prevention of several chronic diseases. However, data on the association between physical activity and multimorbidity are lacking. Using data from 1007 men and women aged 65-94 years who participated in the population-based KORA (Cooperative Health Research in the Region of Augsburg)-Age project conducted in Augsburg/Germany and two adjacent counties in 2008/09, 13 chronic conditions were identified, and physical activity scores were calculated based on the self-reported physical activity scale for the elderly (PASE). Multivariable sex-specific logistic regression was applied to determine the association of the continuous physical activity score with multimorbidity (≥ 2 out of 13 diseases). Physical activity (mean PASE score±SD) was higher in men (125.1 ± 59.2) than in women (112.2 ± 49.2). Among men, the odds ratio (OR) for multimorbidity was 0.73 (95% CI: 0.60-0.90) for a 1 standard deviation increase of the PASE score. No significant results could be observed for women (OR: 1.05; 95% CI: 0.83-1.33). We demonstrated an inverse association between physical activity and multimorbidity among men. Further prospective studies have to confirm the temporality of effects. Copyright © 2013 Elsevier Inc. All rights reserved.

We prospectively examined associations between intakes of antioxidants (vitamins C, vitamin E, and carotene) and cognitive function and decline among elderly men and women of the Cache County Study on Memory and Aging in Utah. In 1995, 3831 residents 65 years of age or older completed a baseline survey that included a food frequency questionnaire and cognitive assessment. Cognitive function was assessed using an adapted version of the Modified Mini-Mental State examination (3MS) at baseline and at three subsequent follow-up interviews spanning approximately 7 years. Multivariable-mixed models were used to estimate antioxidant nutrient effects on average 3MS score over time. Increasing quartiles of vitamin C intake alone and combined with vitamin E were associated with higher baseline average 3MS scores (p-trend = 0.013 and 0.02 respectively); this association appeared stronger for food sources compared to supplement or food and supplement sources combined. Study participants with lower levels of intake of vitamin C, vitamin E and carotene had a greater acceleration of the rate of 3MS decline over time compared to those with higher levels of intake. High antioxidant intake from food and supplement sources of vitamin C, vitamin E, and carotene may delay cognitive decline in the elderly.

Quantitative ultrasound (QUS) is a relatively easy, reliable, and safe method for bone status assessment, but reference data for Asian males remain scarce. Our study aimed to determine the values for one QUS parameter, the speed of sound (SOS) at the calcaneus, in Malaysian Chinese men and to determine the association between the SOS and several demographic characteristics, such as age, weight, height, and body mass index. Three hundred forty-eight Malaysian Chinese men aged 40 yr and older were recruited, and their calcaneal QUS value was determined using the CM-200 densitometer (Furuno Electric, Nishinomiya City, Japan). The results indicated a significant correlation between SOS and age, and multiple stepwise regression analysis indicated that age and height were important predictors of SOS. A significant reduction in SOS value was observed when men 60 yr and older were compared with men aged 40-49 yr. Compared with the reference data for Japanese males, Chinese men in Malaysia showed higher SOS values across all the age groups studied. In conclusion, there is an age-related decrease in SOS values in Malaysian Chinese men, and the SOS values established in this study can be used as a reference for future studies.

Androgenetic alopecia (AGA) is the most common type of baldness in men. The balding process is associated with the gradual miniaturization of hair follicles and successive hair loss. However, the relative contributions of hair density and diameter to AGA are still unclear. Hair density and hair diameter were investigated in Japanese men with or without AGA to elucidate the importance of these factors in the balding process. Male Japanese subjects with or without AGA (n = 369) were included in this study. Hair appearance at the vertex was evaluated by comparison with a series of standard photographs. Hair density was measured using a phototrichogram-based videomicroscopy technique, and hair diameter was assessed by comparison with a series of calibrated threads on the phototrichogram image. All subjects with AGA were ≥ 25 years of age. The mean percentage of thick hairs (> 80 μm) in all subjects with AGA was significantly lower than that in subjects without AGA aged ≥ 25 years (P < 0·01), but the mean percentage of vellus hairs (< 40 μm) in subjects with AGA was significantly higher (P < 0·001). By contrast, the mean density of the hair in all patients with AGA did not significantly differ from the density of those without AGA aged ≥ 25 years. However, the mean density of the hair in subjects without AGA aged < 25 years was significantly higher than that of both subjects without AGA aged ≥ 25 years (P < 0·001) and all subjects with AGA. Hair loss in men with AGA results mainly from the miniaturization of hair follicles rather than the loss of hair (shedding), at least for individuals who are ≥ 25 years of age and present with AGA. © 2014 British Association of Dermatologists.

To investigate the effects of green tea plus vitamin E in addition to exercise on body composition and metabolic and antioxidant parameters in healthy elderly individuals. Interventional randomized controlled prospective trial. For 12 weeks, 22 elderly men and women (age: 71.1 ± 1.2 years; body mass index: 28.3 ± 0.5 kg/m(2) [mean ± SE]) undertook 30 minutes of moderately intense walking 6 d/wk. They were randomly assigned to ingest either green tea plus vitamin E (GTVE; 3 cups and 400 IU, respectively; n = 11) or placebo (n = 11). Data on anthropometrics, fasting insulin and glucose levels, physical fitness, dietary intake, safety parameters, and biomarkers of oxidation status were recorded and analyzed at the start and end of the study. Though dietary intake was unchanged, improved exercise capacity was followed by a significant reduction in body weight and fasting insulin levels in all participants. Additional consumption of GTVE resulted in a twofold increase in serum vitamin E (from 20.4 to 40.6 μmol/L, p < 0.001) and a decrease of men's and women's waist circumferences (from 100.8 and 95.7 to 96.9 and 85.0 cm, p < 0.05 and p < 0.01, respectively) and fasting glucose levels (from 5.30 to 4.98 mmol/L, p < 0.01). Plasma protein carbonyls dropped (from 0.93 to 0.77 nmol/mg protein, p < 0.05), whereas erythrocyte catalase activities increased (from 26.7 to 29.7 U/g hemoglobin, p < 0.05) in the GTVE group only. Oral peroxidase activities were increased in both groups. A daily dose of GTVE in healthy elderly men and women may improve exercise-induced benefits in body composition and glucose tolerance and may also lower oxidative burden.

Receptor for advanced glycation end products (RAGE) activation by its ligands is implicated in obesity-related metabolic disease and accelerated atherothrombosis. Circulating soluble (sRAGE) and/or endogenous secretory RAGE (esRAGE) may counteract the detrimental effects of RAGE. This study aimed at determining the relationship between circulating RAGE and metabolic syndrome (MetS) incidence among Japanese adult men. This 2-year longitudinal study included 426 Japanese men aged 30-83 years who had no MetS at baseline. Serum esRAGE and sRAGE were assayed by ELISA at baseline. Incident metabolic syndrome, defined according to the Asian cutoff based on the 2009 criteria of the American Heart Association Scientific Statements, was evaluated after the 2-year follow-up. During the follow-up period, 55 participants (12.9%) had newly diagnosed MetS. In the multiple logistic models comparing MetS risk in the lowest with that in the highest tertile of baseline esRAGE, a high serum esRAGE level was found to be significantly associated with a low risk of MetS [odds ratios (95% confidence interval), 0.37 (0.14-0.95); P for trend = 0.038] after adjusting for lifestyle and sociodemographic factors, serum high-sensitivity C-reactive protein level, estimated glomerular filtration rate, and MetS components at baseline. Although sRAGE and esRAGE were strongly correlated (r(s) = 0.88), the sRAGE level was not associated with MetS incidence. A high circulating esRAGE level, but not sRAGE level, was associated with a low MetS incidence among Japanese adult men.

Although the important role of social support in mental health is acknowledged, no prospective study has yet examined the relation of social support to suicide. Here, we investigated the association between social support and suicide in a cohort of Japanese men and women. A total of 26,672 men and 29,865 women aged 40-69 years enrolled in the Japan Public Health Center-based prospective study in 1993-1994 completed a self-administered questionnaire which included four items of social support, and were followed for death through December 2005. Hazard ratios (HRs) and 95% confidence intervals (95% CI) of suicidal death by social support index were estimated using a Cox proportional hazards regression model. A total of 180 suicidal deaths were recorded during an average of 12 years' follow-up. Men and women with the highest level of social support had a significantly decreased risk of suicide, with HRs (95% CI) for the highest versus lowest social support group of 0.56 (0.33-0.94) and 0.38 (0.16-0.89) in men and women, respectively. Esteem support and having four or more friends were associated with a lower risk of suicide in women [0.32 (0.13-0.77)] and in both sexes [men: 0.56 (0.36-0.88); women: 0.65 (0.32-1.30)], respectively, whereas confident support was not. These findings suggest that social support may be important for suicide prevention. Avoiding social isolation may decrease the incidence of suicide in men and women, and esteem support can provide additional benefit for women. Copyright © 2011 Elsevier Ltd. All rights reserved.

The tribal population of Telangana, India, lives in remote and difficult conditions. This study was carried out to find out estimate, the prevalence and progression of disability in elderly population among tribals of Khammam District, Telangana state, India. A population based cross sectional survey was conducted in villages of Tribal Sub Plan area. Elderly people who are 60 years or older were chosen with a two stage sampling procedure: (1) probability proportion to size was used to select clusters and (2) in each selected cluster households were selected by systematic random sampling. The participants were interviewed with the 36 item Telugu version of the World Health Organization Disability Assessment Schedule (WHODAS 2.0) questionnaire. Socio- demographic information, behavioral measurements, health and social benefit indicators were also assessed. Descriptive analytical methods were used for prevalence estimation and logistic regression was used to examine the associations of progressive age over disability among elderly. A total of 506 elderly people from 1349 households in 20 villages across 31mandals of Khammam were interviewed. Majority of elderly population among tribals were illiterate (men 88.94%; women 99.33%), used tobacco (men 81.25%; women 57.72%), consumed alcohol (men 80.77%; women 47.32%) and were hypertensive (men 53.85%; women 63.42%). The prevalence of disability was higher in women. Maximum disability in the interviewed elderly population was seen in domains of performing house hold activities, and mobility. In comparison with men, women expressed more disability for majority of domains. As age progressed, the disability for self-care domain increased to a maximum of 2.6 times in men and 6.6 times in women and for mobility domain increased to a maximum of 9.7 times in men and 7.2 times in women. Although present disability modifying mobility Assistive Devices (AD) can help elderly in overcoming disability, these are primarily designed for

Although nonesterified fatty acids (NEFAs) are essential as energy substrate for the myocardium, an excess of circulating NEFAs can be harmful. This study aimed to assess plausible relationships between serum NEFA and mortality due to cardiovascular disease (CVD) in individuals with CKD. This was a prospective cohort study from the third examination cycle of the Uppsala Longitudinal Study of Adult Men, a population-based survey of 1221 elderly men aged 70-71 years residing in Uppsala, Sweden. Data collection took place during 1991-1995. All participants had measures of kidney function; this study investigated 623 (51.7%) of these patients with manifest CKD (defined as either eGFR<60 ml/min per 1.73 m(2) or urine albumin excretion rate ≥20 µg/min). Follow-up for mortality was done from examination date until death or December 31, 2007. After a median follow-up of 14 years (interquartile range, 8-16.8), associations of NEFAs with mortality (related to all causes, CVD, ischemic heart disease [IHD], or acute myocardial infarction) were ascertained. The median serum NEFA was 14.1 mg/dl (interquartile range, 11.3-17.8). No association was found with measures of kidney function. Diabetes and serum triglycerides were the only multivariate correlates of NEFA. During follow-up, 453 participants died, of which 209 deaths were due to CVD, including 88 IHD deaths, with 41 attributed to acute myocardial infarction (AMI). In fully adjusted covariates, serum NEFA was an independent risk factor for all-cause mortality (hazard ratio [HR] per log2 increase, 1.22; 95% confidence interval [95% CI], 1.00 to 1.48) and CVD-related death (HR, 1.51; 95% CI, 1.15 to 1.99), including both IHD (HR, 1.51; 95% CI, 1.00 to 2.32) and AMI mortality (HR, 2.08; 95% CI, 1.09 to 3.98). Elevated serum NEFA associated with CVD mortality, and particularly with mortality due to AMI, in a homogeneous population of older men with moderate CKD.

Both in vivo and in vitro studies have indicated that edible mushrooms may have preventive effects against cognitive impairment. However, few cohort studies have yet examined the relationship between mushroom consumption and incident dementia. We examined the relationship between mushroom consumption and incident dementia in a population of elderly Japanese subjects. Prospective cohort study. Ohsaki Cohort 2006 Study. 13,230 individuals aged ≥65 years living in Ohsaki City, northeastern Japan. Daily mushroom consumption, other lifestyle factors, and dementia incidence. The 5.7 years incidence of dementia was 8.7%. In comparison with participants who consumed mushrooms <1 time/wk, the multi-adjusted HRs (95% CI) for incident dementia among those did so 1-2 times/week and ≥3 times/week were 0.95 (0.81, 1.10) and 0.81 (0.69, 0.95), respectively (P-trend <.01). The inverse association persisted after excluding participants whose dementia event occurred in the first 2 years of follow-up and whose baseline cognitive function was lower. The inverse association did not differ statistically in terms of vegetable consumption (P-interaction = .10). This cohort study suggests that frequent mushroom consumption is significantly associated with a lower risk of incident dementia, even after adjustment for possible confounding factors. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

To evaluate the association between alcohol consumption and the risk for type 2 diabetes (DM) in Japanese. We searched the MEDLINE data base with the key words 'alcohol intake' (or 'alcohol consumption') and 'Japanese' cross-linked with 'diabetes mellitus' (or 'impaired glucose tolerance'). The reports we sought were restricted to prospective cohort studies, randomized controlled trials, meta-analyses and systematic reviews. Computerized and hand searches were conducted in June 2007. Seven prospective cohort studies were adopted. We previously reported that in lean Japanese men (BMI < or =22.0 kg/m2), moderate to heavy alcohol intake is a risk factor for diabetes. One study found heavy alcohol intake to be associated with an increased risk in low-BMI men while moderate alcohol intake was associated with a reduced risk in higher-BMI men. Another study suggested daily alcohol consumption to be a risk factor in low-BMI participants, while being protective in middle-BMI participants. Yet another study demonstrated a U-shaped association between alcohol consumption and the risk of diabetes in men. Three other studies, which did not divide the subjects in terms of BMI values, indicated alcohol intake to be an increased risk for diabetes, two being in men and one being in women, respectively. For a large number of Japanese men who have relatively low BMI, alcohol intake is an established risk factor for diabetes.

The rare hepatitis B virus (HBV) genotype G (HBV/G) coinfects HIV-1-positive individuals along with HBV/A and generates recombinants. However, the circulation of HBV A/G recombinants remains poorly understood. This molecular epidemiologic study examined HBV A/G recombinants in Japanese HIV-1-positive men who have sex with men (MSM). Initially, blood specimens submitted for confirmatory tests of HIV infection in Osaka and Tokyo, Japan, from 2006 to 2013 were examined for HIV-1, and HIV-1-positive specimens were screened for HBV. Among 817 specimens from HIV-1-positive individuals, HBsAg was detected in 59 specimens; of these, HBV/Ae (alternatively A2), a subgenotype of HBV/A prevalent in Europe and North America, was identified in 70.2%, HBV/C in 17.5%, and HBV/G in 10.5%, and HBV/E in 1.8% according to the core gene sequence. The full-length genome analysis of HBV was performed on HBV/G-positive specimens because some HBV A/G recombinants were historically overlooked by genotyping based on a partial genome analysis. It revealed that five of the specimens contained novel Ae/G recombinants, the core gene of which had a high sequence similarity to HBV/G. Detailed analyses showed that novel recombinants were coinfected with HBV/Ae in a recombinant-dominant fashion. No major drug-resistant mutations were found in the newly identified HBV Ae/G recombinants. Some of the individuals asymptomatically coinfected with HIV/HBV suffered mild liver injury. This study demonstrated that novel Ae/G HBV recombinants were identified in Japanese HIV-1-positive MSM. The pathogenicity of novel HBV Ae/G recombinants should be examined in a future longitudinal study. Surveillance of such viruses in HIV-1-positive individuals should be emphasized.

This study investigated the psychometric properties of the Japanese version of the WHOQOL-BREF among 10,693 community-based married Japanese men and women (4376 couples) who were either expecting or raising a child. Analyses of item-response distributions, internal consistency, criterion validity, and discriminant validity indicated that the scale had acceptable reliability and performed well in preliminary tests of validity. Furthermore, dyadic confirmatory factor analysis revealed that the theoretical factor structure was valid and similar across partners, suggesting that men and women define and value quality of life in a similar way.

Objective This study examined the associations of body flexibility with carotid arterial remodelling, including intima–media thickness (IMT) and plaque formation in middle-aged men. Methods The subjects of this cross-sectional study included 1354 Japanese men aged 35–59 years without histories of stroke or cardiac diseases. The arm extensibility test, which can estimate flexibility of the upper extremity (composed of shoulder external rotation and forearm supination), and the sit-and-reach test were performed. Common carotid IMT and plaque formation (≥1.1 mm) were estimated by ultrasound. Results The proportion of subjects who fully completed the arm extensibility test was 55.0%, and who had plaques in the common carotid artery was 37.8%. IMT was associated with poor arm extensibility (β=–0.073, 95% CI –0.02224 to –0.00041, P=0.004), while plaque formation was associated with poor sit-and-reach (OR 0.98579, 95% CI 0.97257 to 0.99919, P=0.038) after adjustment by all covariates. Conclusions This study demonstrated that poor upper extremity and trunk flexibility were associated with characteristics of early onset of atherosclerosis. Furthermore, these associations were independent of covariates such as age, blood pressure, blood lipids glucose levels and abdominal fat accumulation, handgrip strength and lifestyle, including sleeping, drinking, exercise and smoking habits. Poor flexibility may reflect subclinical atherosclerosis in middle-aged men. PMID:29306892

To examine dose/response relationships between habitual physical activity and bone health in the elderly. Longitudinal. Community of Nakanojo. Community-living Japanese aged 65 to 84 (212 men, 284 women). Daily 24-h pedometer/accelerometer data were collected continuously for 5 years. A quantitative calcaneal osteosonic index (OSI) was determined annually. Year-end OSI values were higher in those with greater daily step counts and especially a greater duration of activity >3 metabolic equivalents (METs). However, after controlling for baseline OSI, age and body mass, final OSI values were not significantly greater in the fourth than in the third activity quartile, where men and women, respectively, took means of 7,700 and 7,500 steps/day and/or exercised at an intensity >3 METs for means of 19 and 17 min/day. A multivariate-adjusted proportional hazards model predicted that the OSI values of men and women were, respectively, 2.6 (1.4-4.4) and 3.3 (2.1-5.2) and/or 2.8 (1.5-5.6) and 3.9 (2.4-6.7) times more likely to drop below the OSI fracture threshold over 5 years in the two lowest activity quartiles (<7,000 and <6,900 steps/day and/or <18 and <17 min/day at >3 METs) than in the highest quartile (>9,100 and >8,800 steps/day and/or >30 and >25 min/day at >3 METs). After adjustment for potential confounders, the calcaneal health of seniors is associated with both the daily step count and the duration of activity at an intensity >3 METs. The bone health is optimal in elderly people who take at least 7,000-8,000 steps/day and/or spend at least 15-20 min/day at an intensity >3 METs. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

Although studies in white populations have reported the beneficial effects of intakes of fruit and vegetables (F&V) on bone mass, limited data are available in Asians, especially among the elderly population. We examined the association of F&V intakes and bone mineral status in Chinese elderly adults and explored the potential mechanisms. The study was a population-based cross-sectional study among 4000 Hong Kong Chinese men and women aged 65 years and older. Habitual F&V intakes were ascertained from a validated food frequency questionnaire. Bone mineral measurements of the whole body, hip, lumber spine, and femoral neck were made by dual-energy X-ray absorptiometry. Information on demographic, health, and lifestyles factors was obtained by standardized questionnaire. Relations between F&V intakes and bone mass at various sites were assessed by regression models. Whole-body and femoral neck bone mineral density and content were significantly and positively associated with fruit intake in both men and women, even when adjustment for a range of potential confounders was made. A daily increase of 100 g/kcal total fruit intake was associated with 4.5% and 6.4% increase of BMD at whole body, and 3.9% and 4.8% increase at the femoral neck in men and women, respectively. No significant association was found between vegetable intake and bone mass. The adjustment for vitamin C intake, but not dietary acid load, attenuated the association between fruit intake and bone mass. Greater fruit intake was independently associated with better bone mineral status among Chinese elderly men and women. The association is probably modified by dietary vitamin C.

Recently, aging has been shown to be associated with sarcopenic obesity (SO), of which decreased muscle mass and increased fat mass are features. Sarcopenia and obesity alone are known to be associated with abnormal lipid metabolism. However, it remains unclear whether SO has greater adverse effects on dyslipidemia than on sarcopenia or obesity alone. We aimed to investigate the association between SO and dyslipidemia in elderly Koreans. This study was based on data collected during the 2008-2010 Korea National Health and Nutrition Examination Survey. We included 1,466 men and 2,017 women aged 65 years and over. Sarcopenia was indicated in participants with height- or weight-adjusted appendicular skeletal muscle that was 1 standard deviation below the sex-specific mean for the young reference group, and obesity was defined as a body mass index ≥ 25 kg/m(2). Dyslipidemia was defined according to the National Cholesterol Education Program-Adult Treatment Panel III. After adjusting for confounding factors, the SO group had a higher risk for dyslipidemia [odds ratio (OR) 2.82 (95 % confidence interval 1.76-4.51)] than the obese group [2.12 (1.11-4.07)] and sarcopenic group [1.46 (1.01-2.11)] (p < 0.001) only in men. Furthermore, the SO group in men had the highest OR for hypercholesterolemia, hypertriglyceridemia, hypo-high-density lipoprotein cholesterolemia, hyper-low-density lipoprotein cholesterolemia, and a high ratio of triglyceride to high-density lipoprotein cholesterol even after further adjustments. In Korean elderly men, SO was associated with an increased risk for dyslipidemia compared with sarcopenia or obesity alone.

The relationship of the gastrointestinal microbiome to health and disease is of major research interest, including the effects of the gut microbiota on age related conditions. Here we report on the outcome of a project to collect stool samples on a large number of community dwelling elderly men using the OMNIgene-GUT stool/feces collection kit (OMR-200, DNA Genotek, Ottawa, Canada). Among 1,328 men who were eligible for stool collection, 982 (74%) agreed to participate and 951 submitted samples. The collection process was reported to be acceptable, almost all samples obtained were adequate, the process of sample handling by mail was uniformly successful. The DNA obtained provided excellent results in microbiome analyses, yielding an abundance of species and a diversity of taxa as would be predicted. Our results suggest that population studies of older participants involving remote stool sample collection are feasible. These approaches would allow large scale research projects of the association of the gut microbiota with important clinical outcomes.

Epidemiological longitudinal investigations of the association between not eating three meals regularly and changes in BMI and weight are scarce. The aim of this study was to investigate whether or not regularly eating three meals was associated with changes in BMI and weight in young Japanese men and women. Study participants were 1241 men and 897 women aged 19.0±1.2 and 18.8±0.8years, respectively, who underwent health checkups at a university in Japan in 2001 as the baseline and subsequently in 2003. Weight and height were measured at baseline and 2years later. Whether an individual ate three meals regularly was determined by a self-report questionnaire in 2001. During the 2-year follow-up, the BMI gain was 0.347 for men and 0.067 for women. In the logistic regression analysis, for men, eating three meals irregularly was significantly associated with a 4% BMI gain (OR 1.60, CI 1.11-2.30), 6% BMI gain (OR 1.72, CI 1.12-2.63), 4kg weight gain (OR 2.01, CI 1.29-3.13), 6kg weight gain (OR 1.86, CI 1.02-3.37), and incidence of obesity (BMI ≧ 25)(OR 2.96, CI 1.22-7.17). For women, eating three meals irregularly was significantly associated with a 4% BMI loss (OR 1.99, CI 1.01-3.94), 6% BMI loss (OR 2.79, CI 1.29-6.03), 4kg weight loss (OR 3.85, CI 1.62-9.12), 6kg weight loss (OR 7.65, CI 2.06-28.46), and the incidence of underweight (OR 3.95, CI 1.32-11.89). The current results suggested that eating three meals irregularly was associated with subsequent BMI and weight gains for men and subsequent BMI and weight losses for women; both groups were around 20years of age. Self-reported eating behavior in this study might be used to screen and evaluate young Japanese men and women at high risk for changes in BMI and weight in a practical clinical setting.

Musculoskeletal diseases, especially osteoarthritis (OA) and osteoporosis (OP), impair activities of daily life (ADL) and quality of life (QOL) in the elderly. Although preventive strategies for these diseases are urgently required in an aging society, epidemiological data on these diseases are scant. To clarify the prevalence of knee osteoarthritis (KOA), lumbar spondylosis (LS), and osteoporosis (OP) in Japan, and estimate the number of people with these diseases, we started a large-scale population-based cohort study entitled research on osteoarthritis/osteoporosis against disability (ROAD) in 2005. This study involved the collection of clinical information from three cohorts composed of participants located in urban, mountainous, and coastal areas. KOA and LS were radiographically defined as a grade of > or =2 by the Kellgren-Lawrence scale; OP was defined by the criteria of the Japanese Society for Bone and Mineral Research. The 3,040 participants in total were divided into six groups based on their age: < or =39, 40-49, 50-59, 60-69, 70-79, and > or =80 years. The prevalence of KOA in the age groups < or =39, 40-49, 50-59, 60-69, 70-79, and > or =80 years 0, 9.1, 24.3, 35.2, 48.2, and 51.6%, respectively, in men, and the prevalence in women of the same age groups was 3.2, 11.4, 30.3, 57.1, 71.9, and 80.7%, respectively. With respect to the age groups, the prevalence of LS was 14.3, 45.5, 72.9, 74.6, 85.3, and 90.1% in men, and 9.7, 28.6, 41.7, 55.4, 75.1, and 78.2% in women, respectively. Data of the prevalence of OP at the lumbar spine and femoral neck were also obtained. The estimated number of patients with KOA, LS, and L2-L4 and femoral neck OP in Japan was approximately 25, 38, 6.4, and 11 million, respectively. In summary, we estimated the prevalence of OA and OP, and the number of people affected with these diseases in Japan. The ROAD study will elucidate epidemiological evidence concerning determinants of bone and joint disease.

Green tea is known to have various health benefits for humans. However, the effect of green tea consumption on cognitive dysfunction remains to be clinically verified. We conducted a clinical study to investigate the effects of green tea consumption on cognitive dysfunction. Twelve elderly nursing home residents with cognitive dysfunction (Mini-Mental State Examination Japanese version (MMSE-J) score: <28) participated in the study (2 men, 10 women; mean age, 88 years). The participants consumed green tea powder 2 g/day for 3 months. After three months of green tea consumption, the participants' MMSE-J scores were significantly improved (before, 15.3 ± 7.7; after, 17.0 ± 8.2; p = 0.03). This result suggests that green tea consumption may be effective in improving cognitive function or reducing the progression of cognitive dysfunction; however, long-term large-scale controlled studies are needed to further clarify the effect.

Cross-sectional studies have shown age-related increases in blood docosahexaenoic and eicosapentaenoic acid and decreases in arachidonic acid. We describe serum docosahexaenoic, eicosapentaenoic, and arachidonic acid concentrations over 13 years (1997-2012) across four study waves and serum fatty acid composition over 4 years (2006-2012) between two study waves according to age groups by sex in the same subjects. We included 443 men and 435 women aged 40-79 years at baseline. Serum arachidonic acid concentrations increased in all sex and age groups over 13 years, and eicosapentaenoic or docosahexaenoic acid concentrations increased in males and females who were younger and middle-aged at baseline. Only serum arachidonic acid composition increased over 4 years in men and women who were 40-69 years at baseline, even after adjustment for arachidonic acid intake. These findings suggest a secular increase trend in serum arachidonic acid levels over 13 years among randomly selected community-dwelling middle-aged and elderly Japanese.

This study examined the effects of 6-month nutrition education programs for community-dwelling elderly. This study enrolled 50 community-dwelling elderly who regularly visit outpatient clinics. The programs had three goals: salt reduction, increase in dietary fiber, and adequate protein intake. Since it would be difficult for elderly to achieve all goals concurrently, a single goal was chosen by participants themselves. Anthropometric measurements, blood sampling, and assessment of dietary intake were performed at baseline, 3 months, and 6 months. The nutrition education program for salt reduction was well accepted by the participants and the amount of daily salt intake showed median value of 9.6 g at baseline, 8.0 g at 3 months and 8.1 g at 6 months (P = 0.005). The amount of dietary fiber intake only slightly increased after taking the nutrition program (median value of 13.4 g at baseline, 15.3 g at 3 months and 15.5 g at 6 months; P = 0.695), because of difficulties in introducing new food options to the diet. After taking the adequate protein intake program, participants showed small decreases in protein (a modification from 1.24 g/kg IBW to 1.20 g/kg IBW) and salt intake (8.2 to 7.3 g) at 3 months, but the effects were not sustained at 6 months. This nutrition education program focusing on a single nutrient may serve as a strategy to successfully reduce salt intake and improve systolic blood pressure control in community-dwelling elderly individuals who regularly visit outpatient clinics. In our view, dietary and lifestyle habits should be taken into account as much as possible in nutrition education for elderly individuals.

We examined occupational and industrial differences in lung, gastric, and colorectal cancer risk among Japanese men of working age (25-64 years) using the 2010 Japanese national survey data for occupation and industry-specific death rates. Poisson regression models were used to estimate the age-adjusted incident rate ratios by lung, gastric, and colorectal cancers, with manufacturing used as the referent occupation or industry. Unemployed Japanese men and those in manufacturing had an 8-11-fold increased risk of lung, gastric and colorectal cancer. The highest mortality rates for lung and colorectal cancer by occupation were "administrative and managerial" (by occupation) and "mining" (by industry). For gastric cancer, the highest mortality rate was "agriculture" (by occupation) and "mining" (by industry). By occupation; Japanese men in service occupations, those in administrative and managerial positions, those in agriculture, forestry and fisheries, and those in professional and engineering categories had higher relative mortality risks for lung, gastric, and colorectal cancers. By industry; mining, electricity and gas, fisheries, and agriculture and forestry had the higher mortality risks for those cancers. Unemployed men had higher mortality rates than men in any occupation and industry for all three cancers. Overall, this study suggests that for Japanese men, occupations and industries may be a key social determinant of health.

The dominant congenital disorders Apert syndrome, achondroplasia and multiple endocrine neoplasia–caused by specific missense mutations in the FGFR2, FGFR3 and RET proteins respectively–represent classical examples of paternal age-effect mutation, a class that arises at particularly high frequencies in the sperm of older men. Previous analyses of DNA from randomly selected cadaveric testes showed that the levels of the corresponding FGFR2, FGFR3 and RET mutations exhibit very uneven spatial distributions, with localised hotspots surrounded by large mutation-negative areas. These studies imply that normal testes are mosaic for clusters of mutant cells: these clusters are predicted to have altered growth and signalling properties leading to their clonal expansion (selfish spermatogonial selection), but DNA extraction eliminates the possibility to study such processes at a tissue level. Using a panel of antibodies optimised for the detection of spermatocytic seminoma, a rare tumour of spermatogonial origin, we demonstrate that putative clonal events are frequent within normal testes of elderly men (mean age: 73.3 yrs) and can be classed into two broad categories. We found numerous small (less than 200 cells) cellular aggregations with distinct immunohistochemical characteristics, localised to a portion of the seminiferous tubule, which are of uncertain significance. However more infrequently we identified additional regions where entire seminiferous tubules had a circumferentially altered immunohistochemical appearance that extended through multiple serial sections that were physically contiguous (up to 1 mm in length), and exhibited enhanced staining for antibodies both to FGFR3 and a marker of downstream signal activation, pAKT. These findings support the concept that populations of spermatogonia in individual seminiferous tubules in the testes of older men are clonal mosaics with regard to their signalling properties and activation, thus fulfilling one of the

A 12-year-old boy with photosensitivity since 3 years of age presented with small concavities on both cheeks, the nasal root and the dorsal surface of both hands. According to the clinical features, erythropoietic protoporphyria (EPP) was suspected. Urine and blood samples were tested for porphyrin derivatives, which revealed a markedly elevated level of erythrocyte protoporphyrin (EP) and a diagnosis of EPP was made. The patient's mother had no photosensitivity, however, lesions appearing slightly as small scars were found on the dorsum of her right hand; his elder sister and father showed no rash. The EP levels were elevated in samples from his mother and mildly elevated in those from his elder sister and father. To obtain a definitive diagnosis, genetic analyses were performed using samples from all family members, which revealed no mutations in the ferrochelatase-encoding gene (FECH), which is responsible for EPP. Instead, a pathological mutation of the 5-aminolevulinic acid synthase-encoding gene (ALAS2) was identified in samples from the patient, his mother and his elder sister, confirming a definitive diagnosis of X-linked dominant protoporphyria (XLDPP). This is the first Japanese family reported to have XLDPP, demonstrating evidence of the condition in Japan. In addition, because XLDPP is very similar to EPP in its clinical aspects and laboratory findings, a genetic analysis is required for the differential diagnosis. © 2015 Japanese Dermatological Association.

Examining the sociodemographic determinants of psychological distress is important in identifying specific subgroups in need of further intervention. However, there are few studies focusing on older populations and on the role of gender or location of residence. To try to clarify characteristics of a population at high risk for mental illness, we examined the sociodemographic determinants of psychological distress in older adults living in three different locations. A mail survey was used to collect data on levels of psychological distress and sociodemographic characteristics from a population-based sample of 1894 older adults who lived in Bunkyo (urban setting), Fuchu (suburban setting) and Oyama (rural setting) in Japan (aged 65-74 years, 51.3% men). Psychological distress level was measured based on Kessler's six-item psychological distress scale (K6) and dichotomized into two groups with a cut-off score of 5 (0-4 or 5-24). Multiple logistic regression analyses were used to examine the associations between sociodemographic factors, specifically gender and location of residence, and psychological distress levels. The variables of older age, living in Bunkyo, living in Oyama and living alone were significantly associated with high psychological distress. Although these associations were observed in men, no associations were observed in women. Location-specific analyses showed significant associations between sociodemographic and psychological distress among men living in Oyama, but not among those in Bunkyo or Fuchu. Sociodemographic factors were significantly correlated with psychological distress, particularly among older men in rural areas. Characteristics of a population at high risk for mental illness may vary based on gender and location of residence. Health promotion initiatives for older adults may be more effective if they take these demographic factors into account. © 2013 The Authors. Psychogeriatrics © 2013 Japanese Psychogeriatric Society.

The subjects of this cross-sectional study included 1354 Japanese men aged 35-59 years without histories of stroke or cardiac diseases. The arm extensibility test, which can estimate flexibility of the upper extremity (composed of shoulder external rotation and forearm supination), and the sit-and-reach test were performed. Common carotid IMT and plaque formation (≥1.1 mm) were estimated by ultrasound. The proportion of subjects who fully completed the arm extensibility test was 55.0%, and who had plaques in the common carotid artery was 37.8%. IMT was associated with poor arm extensibility (β=-0.073, 95% CI -0.02224 to - 0.00041, P=0.004), while plaque formation was associated with poor sit-and-reach (OR 0.98579, 95% CI 0.97257 to 0.99919, P=0.038) after adjustment by all covariates. This study demonstrated that poor upper extremity and trunk flexibility were associated with characteristics of early onset of atherosclerosis. Furthermore, these associations were independent of covariates such as age, blood pressure, blood lipids glucose levels and abdominal fat accumulation, handgrip strength and lifestyle, including sleeping, drinking, exercise and smoking habits. Poor flexibility may reflect subclinical atherosclerosis in middle-aged men. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

Background and objectives Although nonesterified fatty acids (NEFAs) are essential as energy substrate for the myocardium, an excess of circulating NEFAs can be harmful. This study aimed to assess plausible relationships between serum NEFA and mortality due to cardiovascular disease (CVD) in individuals with CKD. Design, setting, participants, & measurements This was a prospective cohort study from the third examination cycle of the Uppsala Longitudinal Study of Adult Men, a population-based survey of 1221 elderly men aged 70–71 years residing in Uppsala, Sweden. Data collection took place during 1991–1995. All participants had measures of kidney function; this study investigated 623 (51.7%) of these patients with manifest CKD (defined as either eGFR<60 ml/min per 1.73 m2 or urine albumin excretion rate ≥20 µg/min). Follow-up for mortality was done from examination date until death or December 31, 2007. After a median follow-up of 14 years (interquartile range, 8–16.8), associations of NEFAs with mortality (related to all causes, CVD, ischemic heart disease [IHD], or acute myocardial infarction) were ascertained. Results The median serum NEFA was 14.1 mg/dl (interquartile range, 11.3–17.8). No association was found with measures of kidney function. Diabetes and serum triglycerides were the only multivariate correlates of NEFA. During follow-up, 453 participants died, of which 209 deaths were due to CVD, including 88 IHD deaths, with 41 attributed to acute myocardial infarction (AMI). In fully adjusted covariates, serum NEFA was an independent risk factor for all-cause mortality (hazard ratio [HR] per log2 increase, 1.22; 95% confidence interval [95% CI], 1.00 to 1.48) and CVD-related death (HR, 1.51; 95% CI, 1.15 to 1.99), including both IHD (HR, 1.51; 95% CI, 1.00 to 2.32) and AMI mortality (HR, 2.08; 95% CI, 1.09 to 3.98). Conclusions Elevated serum NEFA associated with CVD mortality, and particularly with mortality due to AMI, in a homogeneous

Metformin is a biguanaide antidiabetic drug used worldwide, and its effectiveness and benefits have already been established. However, the safety of high doses of metformin in Japanese patients, especially in elderly patients with a decreased renal function, remains unclear. Among the side effects of metformin, lactate acidosis is the most problematic due to a high mortality rate. Therefore, we assessed plasma lactate levels in metformin-treated patients to identify independent risk factors for hyperlactemia. 290 outpatients receiving various doses of metformin at our hospital were enrolled between March and July 2014. Serum electrolytes, Cre (creatinine), BUN (blood urea nitrogen), UA (uric acid), HbA1c (hemoglobin A1c), and lactate levels were investigated. Lactate levels did not significantly differ between the elderly (≥75 years) and non-elderly (<75 years) groups. Patients in the elderly group had a significantly lower daily metformin dose and estimated glomerular filtration rate (eGFR), compared with the non-elderly group (both p<0.005). Between with and without hyperlactemia groups, no significant differences were observed in either Cre or age. On the other hand, patients with hyperlactemia had a significantly higher dose of metformin than those without hyperlactemia (p<0.05). In this study, we found that old age and mildly impaired kidney function were not associated with increased lactate levels, and that a higher dose of metformin may be an independent risk factor for elevated lactate levels in Japanese patients.

Billing and Sherman proposed the antimicrobial hypothesis to explain the worldwide spice use pattern. The present study explored whether two antimicrobial ingredients (i.e. spices and vinegar) are used in ways consistent with the antimicrobial hypothesis. Four specific predictions were tested: meat-based recipes would call for more spices/vinegar than vegetable-based recipes; summer recipes would call for more spices/vinegar than winter recipes; recipes in hotter regions would call for more spices/vinegar; and recipes including unheated ingredients would call for more spices/vinegar. Spice/vinegar use patterns were compiled from two types of traditional Japanese cookbooks. Dataset I included recipes provided by elderly Japanese housewives. Dataset II included recipes provided by experts in traditional Japanese foods. The analyses of Dataset I revealed that the vinegar use pattern conformed to the predictions. In contrast, analyses of Dataset II generally supported the predictions in terms of spices, but not vinegar.

Socioeconomic inequalities in morbidity among the elderly; a European overview.

There is some evidence on socioeconomic inequality in morbidity among elderly people, but this evidence remains fragmentary. This study aims to give a comprehensive overview of educational and income inequalities in morbidity among the elderly of eleven European countries. Data from the first wave of 1994 of the European Community Household Panel were used. The study population comprised a total of 14,107 men and 17,243 women, divided into three age groups: 60-69, 70-79 and 80+. Three health indicators were used: self-assessed health, cut down in daily activities due to a physical or mental problem, and long-term disability. The results indicate that socioeconomic inequalities in morbidity by education and income exist among the elderly in Europe, in all the countries in this study and all age groups, including the oldest old. Inequalities decline with age among women, but not always among men. Greece, Ireland, Italy and The Netherlands most often show large inequalities among men, and Greece, Ireland and Spain do so among women. To conclude, inequalities in morbidity decrease with age, but a substantive part persists in old age. To improve the health of elderly people it is important that the material, social and cultural resources of the elderly are improved.

The main purpose of this study is to analyze the effect of a 12-day balneotherapy programme on pain, mood state, sleep, and depression in older adults. In this study, 52 elderly adults from different areas of Spain participated in a social hydrotherapy programme created by the government's Institute for Elderly and Social Services, known as IMSERSO; participants included 23 men (age, 69.74 ± 5.19 years) and 29 women (age, 70.31 ± 6.76 years). Pain was analyzed using the visual analogue scale. Mood was assessed using the Profile of Mood Status. Sleep was assessed using the Oviedo Sleep Questionnaire. Depression was assessed using the Geriatric Depression Scale. The balneotherapy programme was undertaken at Balneario San Andrés (Jaén, Spain). The water at Balneario San Andrés, according to the Handbook of Spanish Mineral Water, is a hypothermic (≥20°C) hard water of medium mineralization, with bicarbonate, sulfate, sodium, and magnesium as the dominant ions. Balneotherapy produced significant improvements (P < 0.05) for all variables (pain, mood state, sleep, and depression) in the total sample. A differential effect was found between the sexes regarding pain improvement, with men, but not women, having significantly improvement (P < 0.01) after treatment. With regard to improving mood, sex differences were also shown, with women, but not men, significantly improved (P < 0.05) in both depression and fatigue. In conclusion, a 12-day balneotherapy programme has a positive effect on pain, mood, sleep quality, and depression in healthy older people. © 2014 The Authors.

Objective To examine the association between adherence to the Japanese Food Guide Spinning Top and total and cause specific mortality. Design Large scale population based prospective cohort study in Japan with follow-up for a median of 15 years. Setting 11 public health centre areas across Japan. Participants 36 624 men and 42 970 women aged 45-75 who had no history of cancer, stroke, ischaemic heart disease, or chronic liver disease. Main outcome measures Deaths and causes of death identified with the residential registry and death certificates. Results Higher scores on the food guide (better adherence) were associated with lower total mortality; the multivariable adjusted hazard ratios (95% confidence interval) of total mortality for the lowest through highest scores were 1.00, 0.92 (0.87 to 0.97), 0.88 (0.83 to 0.93), and 0.85 (0.79 to 0.91) (P<0.001 for trend) and the multivariable adjusted hazard ratio associated with a 10 point increase in food guide scores was 0.93 (0.91 to 0.95; P<0.001 for trend). This score was inversely associated with mortality from cardiovascular disease (hazard ratio associated with a 10 point increase 0.93, 0.89 to 0.98; P=0.005 for trend) and particularly from cerebrovascular disease (0.89, 0.82 to 0.95; P=0.002 for trend). There was some evidence, though not significant, of an inverse association for cancer mortality (0.96, 0.93 to 1.00; P=0.053 for trend). Conclusion Closer adherence to Japanese dietary guidelines was associated with a lower risk of total mortality and mortality from cardiovascular disease, particularly from cerebrovascular disease, in Japanese adults.

An understanding of the trends in regard to coronary risk factors and electrocardiogram (ECG) findings has an important role in public health. We investigated the trends in coronary risk factors and main ECG findings in 1977, 1989, 1999, and 2009 in the Japanese cohort of the Seven Countries Study, in Tanushimaru, a typical farming town on Kyushu Island. A total of 1397 subjects (231 in 1977, 332 in 1989, 389 in 1999, and 445 in 2009) were enrolled in this study, and all of them were males aged over 65 years. In coronary risk factors, total cholesterol levels, diastolic blood pressure, body mass index, and uric acid significantly increased during these 3 decades. The prevalence of smokers markedly decreased from 56.7% in 1977 to 16.8% in 2009. ECG changes during 3 decades were wider QRS interval, increased prevalence of major abnormality, reduced heart rate, shortened PR interval and corrected QT, and decreased prevalence of left ventricular hypertrophy. Age, smoking habits, major and minor abnormalities in ECG were associated with mortality in 1977-1987. Age, total cholesterol levels (inversely) and corrected QT were associated with mortality in 1989-1999. Age, smoking habits, heart rate, and systolic blood pressure were associated with mortality in 1999-2009. Predictors of mortality have changed with the times. Coronary risk factors such as smoking, increased heart rate, and elevated blood pressure have been recently associated with mortalities in elderly male Japanese general population.

The aim of this study was to identify the prevalence of homebound elderly (defined as people whose daily activities were limited to their home) and factors related to it among 300 community elderly residents aged 60 and over in Yamagata city. In 1995, the baseline survey was performed and the follow-up survey was conducted one year later. Subjects were divided into two groups according to the extent of their daily activities: the non-homebound group (defined as people whose daily activities extended into their community) and the homebound group. The main results were as follows; 1. The prevalence of homebound elderly was 7.7% in 1995. 2. Chi-square test or t test was performed to examine the relationship between homebound and various factors. Significant factors were age, history of hypertension, history of mental disease, incompetence of ADLs (walking, eating, toileting, bathing, dressing), interpersonal dependency, subjective health, 'ikigai' (meaningfulness of life), life style (cooking, cleaning, reading newspaper or magazine, watching TV, exercise, associate with friend) and TMIG (Tokyo Metropolitan Institute of Gerontology) index of competence. The present study reveals that daily activities in community elderly residents is related to not only physical factors but also psychosocial factors. Using the significant variables in univariate analysis, multiple logistic regression analysis controlling for age was performed. Significant factors for homebound were incompetence of ADLs (walking, toileting), subjective health and TMIG index of competence. 3. Three out of 214 non-homebound elderly persons in 1995 changed to homebound in 1996.

Elderly Immigrants' Labor Supply Response to Supplemental Security Income.

PubMed

Kaushal, Neeraj

2010-01-01

This paper examined how the 1996 Personal Responsibility and Work Opportunity Reconciliation Act, which banned Supplemental Security Income to the majority of elderly immigrants, affected their employment, retirement, and family incomes. The policy was found to be associated with a 3.5 percentage point (9.5 percent) increase in the employment and a 3.8 percentage point (7 percent) decrease in the retirement of foreign-born elderly men. Partly as a result of their employment response, SSI ineligibility and the consequent decline in SSI receipt did not have any statistically significant effects on the family incomes of elderly foreign-born men. Noncitizen elderly women, on the other hand, did not experience any increase in employment, and those without family support suffered a 10 to 17 percent decline in income. These findings suggest that access to SSI did not create work disincentives for noncitizen elderly women and that SSI restrictions have imposed financial hardship on those without any family support, many of whom perhaps cannot effectively increase their employment.

We examined occupational and industrial differences in lung, gastric, and colorectal cancer risk among Japanese men of working age (25–64 years) using the 2010 Japanese national survey data for occupation and industry-specific death rates. Poisson regression models were used to estimate the age-adjusted incident rate ratios by lung, gastric, and colorectal cancers, with manufacturing used as the referent occupation or industry. Unemployed Japanese men and those in manufacturing had an 8–11-fold increased risk of lung, gastric and colorectal cancer. The highest mortality rates for lung and colorectal cancer by occupation were “administrative and managerial” (by occupation) and “mining” (by industry). For gastric cancer, the highest mortality rate was “agriculture” (by occupation) and “mining” (by industry). By occupation; Japanese men in service occupations, those in administrative and managerial positions, those in agriculture, forestry and fisheries, and those in professional and engineering categories had higher relative mortality risks for lung, gastric, and colorectal cancers. By industry; mining, electricity and gas, fisheries, and agriculture and forestry had the higher mortality risks for those cancers. Unemployed men had higher mortality rates than men in any occupation and industry for all three cancers. Overall, this study suggests that for Japanese men, occupations and industries may be a key social determinant of health. PMID:28230191

To evaluate the safety and efficacy of low-dose desmopressin in elderly men with and without nocturnal polyuria (NP) in real-life practice. Patients with lower urinary tract symptoms (LUTS)/ benign prostate hyperplasia (BPH) who were≧ 65 years old with refractory nocturia were enrolled in this study. We retrospectively analysed elderly men treated with adding desmopressin to current medications for nocturia according to category of the baseline nocturnal urine volume. The 48-h frequency volume chart (FVC), International Prostate Symptom Score (IPSS) and quality of life (QoL) were initially assessed and re-evaluated 12 weeks later. Serum sodium level was checked 1 week, 4 weeks, and 12 weeks after initiation of desmopressin therapy or suspected hyponatremia event. The mean change in numbers of nocturnal voids was evaluated for efficacy of treatment. A total of 136 patients were included with 55 in non-NP group and 81 in NP group. Hypertension was more common in NP group in regard of comorbidities. During treatment period, there were significant reductions of nocturnal voids from 4.22 ± 1.38 to 2.31 ± 0.98 (p < 0.001) in non-NP group and from 4.52 ± 1.23 to 2.07 ± 0.89 (p < 0.001) in NP group. The reduction in nocturnal voids was more significant in NP group (2.44 ± 1.15 vs. 1.91 ± 1.48, p = 0.003). The mean decrease in serum sodium levels were 3.89 ± 1.22 mmol/l (p < 0.001) in non-NP group and 4.69 ± 3.5 mmol/l (p < 0.001) in NP group at the extreme value. Long-term treatment with low-dose desmopressin is safe and effective for nocturia with or without NP in elderly patients with LUTS/BPH during real-life practice. Patients should be well informed about the disease and are closely followed. © 2016 John Wiley & Sons Ltd.

There is a high prevalence of suicide among elderly Chinese, and particularly among elderly Chinese women in Mainland China with a prevalence of 19.6 per hundred thousand. Since Chinese individuals may much more highly value education, a cognitive-behavioral package originated by Ricardo Munoz, Ph.D. was adapted for Chinese American subjects. The material was videotaped in eight sessions, approximately 25 minutes in length, to be shown to community subjects who were at least 40 years and over. In addition, a videotape of muscular relaxation techniques was made. A manual written in Chinese about the content of each class, was given to each subject when he/she attended. The experimental group showed significant improvement in the scores in the Hamilton Depression Scale, including the Somatic Subscale in the Hamilton Anxiety Scale. There was no significant improvement in the control group on any of the measures. Thus the study suggests the efficacy of psychoeducational classes in reducing symptoms of depression in non-patient community elderly. Other studies are being conducted among Korean Americans and Japanese Americans in the United States, and also in the Orient among Japanese elderly.

This study was conducted to compare the degree of depression between men and women and to identify factors influencing their depression. Participants in this cross-sectional descriptive study were 263 persons over 65 years old (men: 103, women: 160). Data were collected through face to face interviews using questionnaires and were done in two urban areas in 2010. Research instruments utilized in this study were SGDS, MMSE-K, SRH, FILE, sleep pattern scale, family and friend support scale, and social support scale. Multivariate regression analysis was performed to identify factors influencing depression in elders. The proportions of participants with depression were significantly different between men and women (52.4% vs. 67.5%). Regression model for depression in elderly men significantly accounted for 54%; disease stress (32%), economic stress (10%), perceived health status (4%), and family support, educational level, age, and hypertension. Regression model for depression in elderly women significantly accounted for 47%; disease stress (25%), perceived social loneliness (8%), friend support (5%), family stress (4%), and sleep satisfaction, and family support. Results demonstrate that depression is an important health problem for elders, and show gender differences for factors influencing depression. These results could be used in the developing depression prevention programs.

Mitochondrial DNA 5178 cytosine/adenine (Mt5178 C/A) polymorphism reportedly modulates the effects of coffee consumption on the risk of hypertension, dyslipidemia and abnormal glucose tolerance. The objective of this analysis was to investigate whether Mt5178 C/A polymorphism modifies the effects of coffee consumption on erythrocytic parameters in male Japanese health check-up examinees. A total of 436 men (mean age ± standard deviation, 54.1 ± 7.8 years) were selected from among individuals visiting the hospital for regular medical check-ups. After Mt5178 C/A genotyping, an exploratory cross-sectional analysis assessing the joint effects of Mt5178 C/A polymorphism and coffee consumption on red blood cell counts, hematocrit and hemoglobin was conducted. For Mt5178C genotypic men, after adjustment for age, body mass index, alcohol consumption, habitual smoking and green tea consumption, coffee consumption significantly decreased red blood cell counts (P for trend = 0.022) and hemoglobin (P for trend = 0.035). The risk of anemia, defined as hemoglobin of <14 g/dL, after the aforementioned adjustment, appeared to depend on coffee consumption (P for trend = 0.078), and the adjusted odds ratio for anemia was significantly higher in men who consumed ≥4 cups of coffee per day than in those who consumed <1 cup per day (odds ratio = 3.771, 95% confidence interval: 1.088 to 13.06, P = 0.036). For Mt5178A genotypic men, coffee consumption possibly reduced the risk of anemia (P for trend = 0.049). However, after the aforementioned adjustment, the statistical significance disappeared (P for trend = 0.137). This exploratory cross-sectional analysis suggests that Mt5178 C/A polymorphism modulates the effects of coffee consumption on erythrocytic parameters and the risk of anemia in male Japanese health check-up examinees.

It is unknown whether high-dose angiotensin II receptor blocker therapy or angiotensin II receptor blocker + calcium channel blocker combination therapy is better in elderly hypertensive patients with high cardiovascular risk. The objective of the study was to compare the efficacy of these treatments in elderly, high-risk Japanese hypertensive patients. The OlmeSartan and Calcium Antagonists Randomized (OSCAR) study was a multicenter, prospective, randomized, open-label, blinded-end point study of 1164 hypertensive patients aged 65 to 84 years with type 2 diabetes or cardiovascular disease. Patients with uncontrolled hypertension during treatment with olmesartan 20 mg/d were randomly assigned to receive 40 mg/d olmesartan (high-dose angiotensin II receptor blocker) or a calcium channel blocker + 20 mg/d olmesartan (angiotensin II receptor blocker + calcium channel blocker). The primary end point was a composite of cardiovascular events and noncardiovascular death. During a 3-year follow-up, blood pressure was significantly lower in the angiotensin II receptor blocker + calcium channel blocker group than in the high-dose angiotensin II receptor blocker group. Mean blood pressure at 36 months was 135.0/74.3 mm Hg in the high-dose angiotensin II receptor blocker group and 132.6/72.6 mm Hg in the angiotensin II receptor blocker + calcium channel blocker group. More primary end points occurred in the high-dose angiotensin II receptor blocker group than in the angiotensin II receptor blocker + calcium channel blocker group (58 vs 48 events, hazard ratio [HR], 1.31, 95% confidence interval, 0.89-1.92; P=.17). In patients with cardiovascular disease at baseline, more primary events occurred in the high-dose angiotensin II receptor blocker group (HR, 1.63, P=.03); in contrast, fewer events were observed in the subgroup without cardiovascular disease (HR, 0.52, P=.14). This treatment-by-subgroup interaction was significant (P=.02). The angiotensin II receptor blocker and

Occupational gender stereotypes: is the ratio of women to men a powerful determinant?

PubMed

Adachi, Tomoko

2013-04-01

Gendered division of occupational choices still exists in contemporary Japanese society. Women are underrepresented in traditionally male-dominated fields, while few men occupy positions in traditionally female-dominated areas. The purpose of the present study was to examine occupational gender stereotypes and its relation to the female-to-male ratio of jobholders. Participants were 540 Japanese (262 women, 278 men) who participated in an Internet survey. The results showed that the female-to-male ratio of jobholders was a strong predictor of gender stereotyping. That is to say, contemporary Japanese recognized male-dominated occupations as typically masculine and female-dominated ones as typically feminine. Gender comparisons revealed that men rated female-dominated occupations as more feminine in nature than did women, while women rated male-dominated occupations as more masculine than did men. Future implications for career interventions focusing on occupational gender stereotypes were also discussed.

The proportion of elderly in the population is increasing due to a falling birth rate and increased life expectancy, and suicide rates increase with age. Trends in elderly suicide rates over a 24-year period, 1979 to 2002, were examined. Differences in suicide rates between elderly men and women and between the age-bands 65 to 74 years and 75+ years were examined. Data was ascertained from the WHO website. Suicide rates for men and women for the age-bands 65 to 74 years and 75+ years declined over the 24-year study period. Suicide rates were higher in men than women for both the age bands. In men, suicide rates were higher in the 75+ age-band than in the 65 to 74 years age-band. Various national initiatives may have contributed to the decline in suicide rates. The challenge will be to sustain the decline, given that the population is ageing and suicide rates generally increase with age.

Golimumab has been proven as an effective treatment for rheumatoid arthritis in clinical trials. However, there is a scarcity of data regarding its use in elderly patients in a real-world setting. This study aims to evaluate the safety, effectiveness, and treatment persistence of golimumab in elderly Japanese patients (≥ 75 years) with rheumatoid arthritis. This study was a post hoc analysis of post-marketing surveillance data on 5137 Japanese patients with active rheumatoid arthritis who received golimumab for 24 weeks. The study population was divided into two age groups (younger: < 75 years and elderly: ≥ 75 years), and the safety, effectiveness, and treatment persistence of golimumab were assessed. Also, the reasons for discontinuing golimumab treatment were analyzed by multi-logistic regression. During golimumab treatment over 24 weeks, younger and elderly groups exhibited comparable improvement of disease activity as measured by EULAR response criteria with similar overall rates of adverse events. However, the survival curve of golimumab for elderly patients was significantly different from that for younger patients due largely to the discontinuation at 4 weeks. The most common reason for discontinuation in elderly patients was patient choice, while it was disease progression in younger patients. Analysis of elderly patients who discontinued treatment by their own decision identified EULAR good response as a factor associated with continuation of golimumab treatment whereas no predictive factor associated with discontinuation was identified. The safety and effectiveness of golimumab treatment in elderly Japanese patients aged 75 years or older were comparable to those in younger patients in real-world clinical practice. Analysis of the survival curves suggested that continuous use of golimumab might further improve clinical benefit of golimumab in elderly patients, underpinning the importance of effective communication between physicians and

Erectile dysfunction (ED) is a major complication after radical prostatectomy (RP); however, debate continues regarding the efficacy of penile rehabilitation in the recovery of the postoperative erectile function (EF). This study included a total of 103 consecutive sexually active Japanese men with localized prostate cancer undergoing nerve-sparing RP, and analyzed the postoperative EF, focusing on the significance of penile rehabilitation. In this series, 24 and 79 patients underwent bilateral and unilateral nerve-sparing RPs, respectively, and 10 or 20 mg of vardenafil was administered to 35 patients at least once weekly, who agreed to undergo penile rehabilitation. Twelve months after RP, 48 (46.6%) of the 103 patients were judged to have recovered EF sufficient for sexual intercourse without any assistance. The proportion of patients who recovered EF in those undergoing penile rehabilitation (60.0%) was significantly greater than that in those without penile rehabilitation (38.2%). Of several parameters examined, the preoperative International Index of Erectile Function-5 (IIEF-5) score and nerve-sparing procedure were significantly associated with the postoperative EF recovery rates in patients with and without management by penile rehabilitation, respectively. Furthermore, univariate analysis identified the preoperative IIEF-5 score, nerve-sparing procedure and penile rehabilitation as significant predictors of EF recovery, among which the preoperative IIEF-5 score and nerve-sparing procedure appeared to be independently associated with EF recovery. Considering these findings, despite the lack of independent significance, penile rehabilitation with low-dose vardenafil could exert a beneficial effect on EF recovery in Japanese men following nerve-sparing RP.

Sodium-glucose co-transporter 2 inhibitors are a promising treatment for type 2 diabetes mellitus, but are associated with concerns about specific adverse drug reactions. We carried out a 1-year post-marketing surveillance of tofogliflozin, a novel agent in this class, in Japanese elderly patients with type 2 diabetes mellitus and here report the results of a 12-week interim analysis, focusing on adverse drug reactions of special interest. The present prospective observational study included all type 2 diabetes mellitus patients aged ≥65 years who started tofogliflozin during the first 3 months after its launch. Data on demographic and baseline characteristics, clinical course and adverse events were collected. Of 1,535 patients registered, 1,506 patients whose electronic case report forms were collected and who had at least one follow-up visit were included in the safety analysis at 12 weeks. A total of 178 of 1,506 patients (11.82%) had at least one adverse drug reaction to tofogliflozin. The incidence of adverse drug reactions of special interest (polyuria/pollakiuria, volume depletion-related events, urinary tract infection, genital infection, skin disorders and hypoglycemia) was 2.19, 2.32, 1.33, 1.13, 1.46 and 0.73%, respectively. No new safety concerns were identified. Among those evaluable for clinical effectiveness, the mean (standard deviation) glycated hemoglobin decreased from 7.65% (1.35%) at baseline to 7.25% (1.16%) at 12 weeks by 0.39% (0.94%; P < 0.0001). This interim analysis characterized the safety profile of tofogliflozin in Japanese elderly patients with type 2 diabetes mellitus during the early post-marketing period. © 2016 The Authors.

The purpose of this study was to compare the most important life events reported by U.S. and Japanese centenarians. This study included a population-based sample of 239 U.S. centenarians from the Georgia Centenarian Study and 304 Japanese centenarians from the Tokyo Centenarian Study. Two open-ended life events questions were categorized and grouped into different life event domains. Several cross-tabulations were computed to investigate culture and gender differences in most important life event domains. Next, four configural frequency analyses were conducted using Neuroticism, Extraversion, and the first most often mentioned life event domain for each sample (i.e., marriage and historical life events). Results suggest that events related to marriage were the most frequent important event domains mentioned by U.S. centenarians. The Japanese sample was more likely to report historical events. Men from the U.S. were more likely to report events related to work and retirement compared to U.S. women, and U.S. women reported events related to family as the most important life events when compared to U.S. men. Japanese women considered events related to marriage, death and grief as the most important life events when compared to Japanese men. In addition, Japanese men reported events related to work and retirement as the most important life events. A cross-cultural difference was found in life events: U.S. centenarians were more likely to mention positive experiences related to marriage and children, whereas Japanese centenarians reported mostly negative and traumatic experiences such as historical, death/grief, and work/retirement events.

OBJECTIVE To elucidate the association between vital capacity and the presence of selected metabolic diseases in middle-aged Japanese men. METHODS A cross-sectional analysis of the associations among forced vital capacity (FVC), static vital capacity as a percentage of that predicted (%VC) and the presence of metabolic diseases was performed. RESULTS In a univariate linear regression analysis, FVC and %VC were inversely associated with poor vegetable intake, cigarette smoking and body mass index, but not with physical activity or ethanol consumption. In a logistic regression analysis adjusted for lifestyle factors, body mass index and age, the odds ratios for the presence of metabolic disease per 0.54 L (1 SD) decrease in FVC were 1.24 (95% CI 1.03 to 1.50) for type II diabetes, 1.21 (95% CI 1.02 to 1.42) for hypertension, 1.34 (95% CI 1.11 to 1.63) for hypertriglyceridemia, 1.23 (95% CI 1.03 to 1.46) for high gamma-glutamyl transferase levels and 1.63 (95% CI 1.10 to 2.41) for an episode of cardiovascular disease. FVC did not correlate with hyperhomocysteinemia, hypercholesterolemia or high white blood cell count. Similar results were also obtained for the association between %VC and metabolic diseases. CONCLUSIONS A decrease in FVC or %VC was associated with the presence of some metabolic diseases. The association may partly explain the reported association between low FVC and cardiovascular disease. PMID:16550264

Background: The Pravastatin Anti-atherosclerosis Trial in the Elderly (PATE) found that the prevalence of cardiovascular events (CVEs) was significantly lower with standard-dose (10–20 mg/d) pravastatin treatment compared with low-dose (5 mg/d) pravastatin treatment in elderly (aged ⩾ 60 years) Japanese patients with hypercholesterolemia. Small differences in on-treatment total cholesterol and low-density lipoprotein cholesterol (LDL-C) levels between the 2 dose groups in the PATE study were associated with significant differences in CVE prevalence. However, the reasons for these differences have not been determined. How sex and age differences influence the effectiveness of pravastatin also remains unclear. Objectives: The aims of this study were to determine the relationship between reduction in LDL-C level and CVE risk reduction in the PATE study and to assess the effects of sex and age on the effectiveness of pravastatin treatment (assessed using CVE risk reduction). Methods: In this post hoc analysis, Cox regression analysis was performed to study the relationship between on-treatment (pravastatin 5–20 mg/d) LDL-C level and CVE risk reduction using age, sex, smoking status, presence of diabetes mellitus and/or hypertension, history of cardiovascular disease (CVD), and high-density lipoprotein cholesterol level as adjustment factors. To explore risk reduction due to unspecified mechanisms other than LDLrC reduction, an estimated Kaplan-Meier curve from the Cox regression analysis was calculated and compared with the empirical (observed) Kaplan-Meier curve. Results: A total of 665 patients (527 women, 138 men; mean [SD] age, 72.8 [5.7] years) were enrolled in PATE and were followed up for a mean of 3.9 years (range, 3–5 years). Of those patients, 50 men and 173 women were ⩾75 years of age. Data from 619 patients were included in the present analysis.

This study aims to investigate the association of long-term weight-change slopes, weight fluctuation and the risk of type 2 diabetes mellitus (T2DM) in middle-aged Japanese men and women. A total of 4234 participants of Aichi Workers' Cohort Study who were aged 35-66 years and free of diabetes in 2002 were followed through 2014. Past body weights at the ages of 20, 25, 30, 40 years, and 5 years before baseline as well as measured body weight at baseline were regressed on the ages. Slope and root-mean-square-error of the regression line were obtained and used to represent the weight changes and the weight fluctuation, respectively. The associations of the weight-change slopes and the weight fluctuation with incident T2DM were estimated by Cox proportional hazards models. During the median follow-up of 12.2 years, 400 incident cases of T2DM were documented. After adjustment for baseline overweight and other lifestyle covariates, the weight-change slopes were significantly associated with higher incidence of T2DM (hazard ratio (HR): 1.80, 95% confident interval (CI): 1.17-2.77 for men; and HR: 2.78, 95% CI: 1.07-7.23 for women), while the weight fluctuation was not (HR: 1.08, 95% CI: 1.00-1.18 for men and HR: 1.02, 95% CI: 0.84-1.25 for women). Regardless of the presence of overweight, the long-term weight-change slopes were significantly associated with the increased risk of T2DM; however, the weight fluctuation was not associated with the risk of T2DM in middle-aged Japanese men and women.

Eating behaviour depends partly on food preference, which may be determined by different types of emotions. Among the emotions generated by food, disgust and pleasure are common and can lead to increased and reduced food consumption. We tested the hypothesis that (1) elderly men and women felt different emotions towards food, and (2) low energy intake is related to negative emotions towards food. In February 2004, a convenience sample of elderly participants was recruited locally by telephone. Food intake of 52 elderly people, aged 63-80 years, was monitored throughout each day for one week and made it possible to assign the elderly people to two groups (low and high energy intake from food consumption data). One month later, each of them assessed their likes or dislikes towards 30 food pictures (vegetables, cheeses, fruits, starchy foods, sweets, meat, fish, offal and eggs) using 19 emotional words (eight words with a positive valence: 'to like', 'thrilled', 'satisfaction', 'surprise', 'serene', 'amused', 'pride', 'interest', and 11 other words with a negative valence: 'disgust', 'indifference', 'guilt', 'uneasiness', 'nostalgia', 'impatience', 'doubt', 'frustration', 'embarrassment', 'disappointment' and 'lassitude'. The emotional intensities experienced with the different pictures were analysed by ANOVA for each group (men and women, small and big eaters). There were differences in likes and dislikes between men and women. Both guilty and liking scores towards food were generally higher in women than in men. Small eaters felt more doubt, unease, disappointment and indifference towards food than big eaters. In conclusion, the report of low food intake was related to more negative emotions towards foods that might be associated with the willingness to restrict food intake or to undernutrition.

Background The cognitive reserve hypothesis would predict that use of written Japanese should confer protection against dementia because of the complexity of its ideograms compared with written English. We sought to test this hypothesis in analyses from a longitudinal study of Japanese-American men. Methods Participants were second-generation Japanese-American men (Nisei) on the island of Oahu, Hawaii, who were seen in 1965 and in subsequent examinations to detect dementia beginning in 1991-1993. Use of spoken and written Japanese was self-reported in 1965 (Analyses 1 and 2), and mid-life use of written Japanese and written English was self-reported in 1994-1996 (Analysis 3). We analyzed prevalent dementia outcomes in 1991-1993 (Analysis 1, n=3,139) using logistic regression, and incident dementia outcomes in 1994-2002 (Analysis 2, n=2,299) and in 1997-2002 (Analysis 3, n=1,655) using Cox proportional hazards regression. Dementia outcomes included all-cause dementia, probable and possible Alzheimer disease, and probable vascular dementia. We adjusted models for probable and possible confounders. Results Participants who reported proficiency with written Japanese were older and had lower incomes. For Analysis 1, there were 154 prevalent cases of dementia, 74 of Alzheimer disease, and 43 of vascular dementia; for Analysis 2, 236 incident cases of dementia, 138 of Alzheimer disease, and 45 of vascular dementia; and for Analysis 3, 125 incident cases of dementia, 80 of Alzheimer disease, and 20 of vascular dementia. There was no relationship in adjusted models between self-reported proficiency with written Japanese and any dementia outcomes. Conclusions Proficiency with written Japanese does not appear to be protective for dementia. PMID:19593152

Why are women slimmer than men in developed countries?

Women have a lower BMI than men in developed countries, yet the opposite is true in developing countries. We call this the gender BMI puzzle and investigate its underlying cause. We begin by studying time trends in Japan, where, consistent with the cross-country puzzle, the BMI of adult women has steadily decreased since the 1950s, whereas the BMI of adult men has steadily increased. We study how changes in energy intake and energy expenditure account for the over-time gender BMI puzzle using the Japanese National Nutrition Survey from 1975 to 2010, which provides nurse-measured height and weight and nutritionist-assisted food records. Because long-term data on energy expenditure do not exist, we calculate energy expenditure using a steady-state body weight model. We then conduct cross-country regression analysis to corroborate what we learn from the Japanese data. We find that both energy intake and energy expenditure have significantly decreased for Japanese adult men and women and that a larger reduction in energy expenditure among men than women accounts for the increasing male-to-female BMI gap. Trends in BMI and energy expenditure vary greatly by occupation, suggesting that a relatively large decrease in physical activity in the workplace among men underlies the gender BMI puzzle. The cross-country analysis supports the generalizability of the findings beyond the Japanese data. Furthermore, the analysis suggests the increasing male-to-female BMI gap is driven not only by a reduction in the energy requirements of physically demanding work but also by weakening occupational gender segregation. No support is found for other explanations, such as increasing female labor force participation, greater female susceptibility to malnutrition in utero, and gender inequality in nutrition in early life.

The study aimed to identify the felt common health problems, utilisation of health services and unmet needs of urban and rural elderly people of Bhaktapur district, Nepal. It was a cross sectional population study of people aged 60 years or more where 204 respondents were interviewed in 2009. The common felt problems were pain and swelling of joints (65.7%), indigestion (63.7%), excessive tiredness (38.2%) and hypertension (35.8%). Pain and swelling of joints (72.5%) and back pain (40.4%) were higher in rural elderly population whereas indigestion (67.6%) and hypertension (37.85%) were higher in urban population. Pain and swelling of joints (66.7%) and indigestion (69.6%) were higher in males, and hypertension (50.0%), back pain (38.2%) and chronic bronchitis/asthma (39.2%) were higher in females. The unmet needs varied between different health problems. In general women had more unmet needs than men, where 80 unmet needs were identified for the 102 men compared with 105 for the 102 women, and these unmet needs increased dramatically with age. This approach yields new insights into the health care needs of the elderly and will be helpful to health care planners.

The purpose of this study was to determine lifestyle factors in the elderly that affected longevity, using a population-based prospective study. The participants were 440 men and 625 women aged 60 to 74 living in a rural Japanese community. The baseline data such as age, sex, present illness, walking hours per day, sleeping hours per day, alcohol consumption, a history of smoking, and "ikigai" (meaningfulness of life) were collected in July 1990. During 90 months of follow-up from July 1990 to December 31 1997, there were 123 deaths. By Cox's multivariate hazard model adjusted age, sex, and medical histories, walking > or = 1 hour/day (HR = 0.63, 95% CI 0.44-0.91) and an "ikigai" (HR = 0.66, 95% CI 0.44-0.99) lowered the risk for all-cause mortality independently. In regard to hours of sleep, the cumulative survival curve showed that 7 hours/day was the border and sleeping > or = 7 hours/day lowered the risk (HR = 0.49 95% CI 0.33-0.74). Based on the findings in this study, walking > or = 1 hour/day, sleeping > or = 7 hours/day, and "ikigai" are important factors for longevity in the elderly.

Background: Little is known about the effects of overall dietary pattern on lead concentration. Objective: We examined the association of overall dietary patterns, derived from a semiquantitative food frequency questionnaire, with bone and blood lead concentrations. Methods: These longitudinal analyses included mostly non-Hispanic white, middle-aged-to-elderly men from the Veterans Affairs Normative Aging Study. Long-term lead exposures were measured as tibia and patella lead concentrations by using K-shell-X-ray fluorescence. Short-term lead exposures were measured as blood lead concentrations by using graphite furnace atomic absorption spectroscopy. Dietary pattern scores were derived by using factor analysis. Linear mixed-effects models were utilized to predict blood lead concentrations among 983 men, aged 44-92 y at baseline, with a total of 3273 observations (during 1987-2008). We constructed linear regression models to determine the relations between dietary patterns and bone lead concentrations among 649 participants with an age range of 49-93 y. Results: Two major dietary patterns were identified: a prudent dietary pattern, characterized by high intakes of fruit, legumes, vegetables, whole grains, poultry, and seafood; and a Western dietary pattern, characterized by high intakes of processed meat, red meat, refined grains, high-fat dairy products, French fries, butter, and eggs. After adjusting for age, smoking status, body mass index, total energy intake, education, occupation, neighborhood-based education and income level, men in the highest tertile of the Western pattern score (compared with the lowest) had 0.91 μg/dL (95% CI: 0.41, 1.42 μg/dL) higher blood lead, 5.96 μg/g (95% CI: 1.76, 10.16 μg/g) higher patella lead, and 3.83 μg/g (95% CI: 0.97, 6.70 μg/g) higher tibia lead. No significant association was detected with the prudent dietary pattern in the adjusted model. Conclusions: These findings suggest that the Western diet is associated with

Polychlorinated biphenyls (PCB)/polychlorinated dibenzofurans (PCDF) are known to affect central nervous functioning. In recent studies, elderly patients who have been exposed to these have been noted to have psychological deficits. There is little known about which test is sensitive to neurotoxins in cognitive evaluation. The objective of the present study was to compare the significance between selective psychological tests in cognitive assessment in PCB-laden elderly. A retrospective PCB/PCDF exposed cohort was observed. Exposed elderly aged ≥ 60 years and registered in Central Health Administration were enrolled, and similar age- and sex-matched subjects served as non-exposed controls. The Mini-Mental State Examination (MMSE) and Attention and Digit Span (ADS) were tested in both groups. Student's t-test, χ(2) -test and linear regression models were used for statistical analysis.  A total of 165 exposed patients and 151 controls were analyzed. The exposed group included 49% men, a mean age of 69.3 ± 6.4 years and an education level of 4.0 ± 3.9 years. The controls included 52% men, a mean age of 69.9 ± 5.5 years and an education level of 4.5 ± 3.2 years. There was no statistical difference in MMSE before and after adjusting for the confounding variables of age, sex and education (P= 0.16 vs P= 0.12). However, ADS-forward and ADS-total scores showed a significant decline in the exposed subjects (P= 0.0001 vs P= 0.001). Using a linear regression among stratified PCB and cognitive functioning (≤30 ppb; 31-89; ≥90), a dose effect was found at the medium (31-89 ppb) and high exposure (≧90 ppb) levels. Our observations showed attention and short-term memory were impaired in PCB-laden elderly patients. Higher exposure level showed lower cognitive functioning in ADS. The MMSE was insensitive to neurotoxins. The present study shows that the selective test has a decisive role in toxic-related cognitive assessments. © 2010 The Authors. Psychogeriatrics �

The study examined the subjective life experiences of elderly first-generation Korean women living in Japan and investigated their adjustment to the local Japanese community. The study group comprised 14 elderly Korean women residents at a Korean-oriented, insurance-based, day services center in midwestern Japan. They were interviewed in depth, and the data were analyzed using the modified grounded theory approach. The study designated the core category as "conservation of ethnic identity" and identified five subcategories: (a) loneliness, (b) returning to one's homeland culture, (c) physical decline as a result of aging, (d) family ties, and (e) a place where one belongs. The results elucidated that although the participants had adapted to Japanese culture, they were strongly influenced by the memories of their hometowns and wished to return to their homeland. The study suggests that elderly immigrants need day care support that provides an environment where they can enjoy their culture.

There are few studies on anthropometry and nutritional status in large and representative samples of elderly populations in Chile and South America. We describe age and sex differences in weight, height, body mass index, knee height, waist circumference, midarm circumference, triceps skinfold thickness, arm muscle area, and calf circumference in Chilean elderly subjects. This was a population-based, cross-sectional study. A total of 1220 elderly persons (819 women and 411 men; age range, 60-99 y) were recruited in the city of Santiago (Chile) through a probabilistic sampling procedure carried out from October to December 1999. Men were significantly heavier and taller than women in all age groups, whereas body mass index values were significantly higher in women than in men. All anthropometric variables showed a decrease in average values with aging in men and women. The apparent negative slopes for the decline in average values of body weight with aging was of greater magnitude in women than in men (-0.42 kg/y and -0.54 kg/y in male and female subjects, respectively). However, significant age x sex interaction was detected only for triceps skinfold thickness. In women, quadratic terms for age provided a significantly better fit than did the simple linear model for the association between age and weight, body mass index, waist circumference, triceps skinfold thickness, calf circumference, or midarm circumference. These observations indicated that body weight changes associated with aging might be more severe in Chilean women than in men, probably determining a differential pattern of lean and fat mass loss.

During the periods of seasonal flu in 2003 and 2004, it was found that about 45 percent of elderly people in Japan had been inoculated with influenza vaccines. Comparatively, however, the proportion of inoculation with pneumococcal vaccine was only 0.1 percent. Taking into account such incongruent proportions, this study assesses health and economic benefits of vaccination strategies for both influenza and pneumonia particularly for the elderly population in Japan. To accomplish this objective, a cost-effectiveness analysis was conducted with the use of the Monte Carlo simulation based on the data from medical literature as well as from the public organizations, wherein three strategic patterns were delineated and compared (i) no vaccination (ii) influenza vaccine only, and (iii) combined influenza with pneumococcal vaccines. The cost for one year of life saved by each strategy was compared with the scenario of no vaccinations. It was found that for 100,000 elderly people over 65 years of age in Japan, the cost-effectiveness ratio of influenza-only vaccination was 516,332 Japanese yen per one year of life saved, while the combined vaccinations of influenza with pneumococcal was 459,874 Japanese yen for the same benefit. The incremental cost-effectiveness ratio of the strategies (iii) versus (ii) was 426,698 Japanese yen per one year of life saved for 100,000 people. Consequently it was indicated that the combined vaccinations would be more cost-effective than the vaccination for influenza only.

Previously, we found significantly higher serum leptin in Japanese-Americans in Hawaii than Japanese in Japan. We investigated whether differences in dietary and other lifestyle factors explain higher serum leptin concentrations in Japanese living a Western lifestyle in Hawaii compared with Japanese in Japan. Serum leptin and nutrient intakes were examined by standardized methods in men and women ages 40-59 years from two population samples, one Japanese-American in Hawaii (88 men, 94 women), the other Japanese in central Japan (123 men, 111 women). Multiple linear regression models were used to assess role of dietary and other lifestyle traits in accounting for serum leptin difference between Hawaii and Japan. Mean leptin was significantly higher in Hawaii than Japan (7.2 ± 6.8 vs 3.7 ± 2.3 ng/ml in men, P < 0.0001; 12.8 ± 6.6 vs 8.5 ± 5.0 in women <0.0001). In men, higher BMI in Hawaii explained over 90% of the difference in serum leptin; in women, only 47%. In multiple linear regression analyses in women, further adjustment for physical activity and dietary factors--alcohol, dietary fiber, iron--produced a further reduction in the coefficient for the difference, total reduction 70.7%; P-value for the Hawaii-Japan difference became 0.126. The significantly higher mean leptin concentration in Hawaii than Japan may be attributable largely to differences in BMI. Differences in nutrient intake in the two samples were associated with only modest relationship to the leptin difference. Copyright © 2010 Elsevier B.V. All rights reserved.

Adequate protein intake is crucial to maintain muscle protein content in elderly subjects, but quality of dietary proteins should be considered. The aim was to determine whether soluble milk protein offers an original strategy to increase muscle anabolism in elderly subjects via a synergistic effect of fast-digesting proteins together with a unique essential AA content. We investigated the effect of a 10-day adequate-protein (AP) or high-protein (HP) diet together with the protein source as caseins (CAS) or soluble milk proteins (PRO) on specific muscle protein fractional synthesis rates (FSRs) in healthy elderly men (71.8 ± 2.4 yr, n = 31). The isotopic study consisted of two periods of 4 h each: a post-absorptive and a postprandial period. The fed state was defined by consumption of either 15 g or 30 g of PRO or CAS, given fractionally every 20 min for 4 h. Soluble milk proteins are produced using a membrane process directly from pasteurized milk. Specific muscle protein FSRs were measured during both postabsorptive and postprandial period using a continuous infusion of l-[1-(13)C]leucine. FSR of sarcoplasmic muscle proteins and actin did not increase significantly in the postprandial state compared to postabsorptive state, whereas myosin FSR rate was increased by feeding whatever the protein source in HP groups (0.024 ± 0.005 vs 0.053 ± 0.011% h(-1), P < 0.05 and 0.026 ± 0.004 vs 0.050 ± 0.005% h(-1), P < 0.004 for PRO HP and CAS HP) but only with the PRO meal in the AP groups (0.031 ± 0.003 vs 0.062 ± 0.009% h(-1), P < 0.03 for PRO AP). Mitochondrial muscle protein FSR was also increased by feeding, irrespective of the protein quantity, but only in PRO meal groups (P < 0.02). Fast-digesting soluble milk proteins improved postprandial muscle protein synthesis, especially mitochondrial muscle proteins and myosin fractional synthesis rates, in elderly subjects.

Erectile dysfunction in the elderly: epidemiology, etiology and approaches to treatment.

Seftel, Allen D

2003-06-01

Erectile dysfunction is experienced at least some of the time by most men who have reached 45 years of age, and it is projected to affect 322 million men worldwide by 2025. The prevalence of erectile dysfunction is high in men of all ages and increases greatly in the elderly. This paper reviews the epidemiology of erectile dysfunction with an emphasis on the experience of older men, normal age related changes in the structure and function of the penis that may contribute to increased risk with age, how the accumulation of risk factors with age may contribute to the high prevalence of the disease in older men, and established and emerging therapies. The normal aging process and age related risk factor accumulation contribute to the increased prevalence of erectile dysfunction in the elderly. Remarkable progress has been made in the treatment of erectile dysfunction. At present inhibition of phosphodiesterase 5 with oral agents such as sildenafil would appear to be the initial treatment of choice. These drugs have been shown to be safe and effective, and sildenafil has demonstrated efficacy in patients with many of the comorbidities observed in older men with erectile dysfunction. New treatments, in particular transfection with genes for key mediators of erectile function that are known to be down-regulated in elderly men, also hold promise. Further research into the neural, vascular and molecular mechanisms involved in penile erection will lead to the development of even safer, more effective and more convenient therapies for men with erectile dysfunction.

This cohort study investigated the association between sugar-sweetened beverage (SSB) and diet soda consumption and the incidence of type 2 diabetes in Japanese men. The participants were 2,037 employees of a factory in Japan. We measured consumption of SSB and diet soda using a self-administered diet history questionnaire. The incidence of diabetes was determined in annual medical examinations over a 7-year period. Hazard ratios (HRs) with 95 % confidence intervals (CIs) for diabetes were estimated after adjusting for age, body mass index, family history, and dietary and other lifestyle factors. During the study, 170 participants developed diabetes. The crude incidence rates (/1,000 person-years) across participants who were rare/never SSB consumers, <1 serving/week, ≥ 1 serving/week and <1 serving/day, and ≥ 1 serving/day were 15.5, 12.7, 14.9, and 17.4, respectively. The multivariate-adjusted HR compared to rare/never SSB consumers was 1.35 (95 % CI 0.80-2.27) for participants who consumed ≥ 1 serving/day SSB. Diet soda consumption was significantly associated with the incident risk of diabetes (P for trend = 0.013), and multivariate-adjusted HRs compared to rare/never diet soda consumers were 1.05 (0.62-1.78) and 1.70 (1.13-2.55), respectively, for participants who consumed <1 serving/week and ≥ 1 serving/week. Consumption of diet soda was significantly associated with an increased risk for diabetes in Japanese men. Diet soda is not always effective at preventing type 2 diabetes even though it is a zero-calorie drink.

Despite the increasing evidence linking aspects of the social environment to a range of health outcomes, important questions remain concerning the precise mechanisms or pathways through which social circumstances exert their influence. Biological pathways are one important area of current research interest. Using data from the Social Environment and Biomarkers of Aging Study (SEBAS) in Taiwan, we examined relationships between social environment characteristics and an index of cumulative biological dysregulation ("allostatic load," AL) in near elderly (NE) (aged 54-70) and elderly Taiwanese (aged 71+). Longitudinal data on levels of social integration and extent of social support were used to predict cumulative AL at the final survey year. Linear regression analyses revealed that among the NE, presence of a spouse between 1996 and 2000 was associated with lower AL in 2000 among men, but not women. Among the elderly, ties with close friends and/or neighbors were found to be significantly related to lower AL for both men and women. Perceived qualities of these social relationships did not show consistent associations with AL. This relatively modest set of significant relationships stands in contrast to somewhat stronger patterns of findings from studies in Western societies. Cross-cultural differences between Western societies and an East Asian society such as Taiwan raise the intriguing possibility that contextual, normative influences on social experience affect the patterns of association between features of these social worlds and the physiological substrates of health.

Because few Japanese questionnaires assess the elderly's appetite, there is an urgent need to develop an appetite questionnaire with verified reliability, validity, and reproducibility. We translated and back-translated the Council on Nutrition Appetite Questionnaire (CNAQ), which has eight items, into Japanese (CNAQ-J), as well as the Simplified Nutritional Appetite Questionnaire (SNAQ-J), which includes four CNAQ-J-derived items. Using structural equation modeling, we examined the CNAQ-J structure based on data of 649 Japanese elderly people in 2013, including individuals having a certain degree of cognitive impairment, and we developed the SNAQ for the Japanese elderly (SNAQ-JE) according to an exploratory factor analysis. Confirmatory factor analyses on the appetite questionnaires were conducted to probe fitting to the model. We computed Cronbach's α coefficients and criterion-referenced/-related validity figures examining associations of the three appetite battery scores with body mass index (BMI) values and with nutrition-related questionnaire values. Test-retest reproducibility of appetite tools was scrutinized over an approximately 2-week interval. An exploratory factor analysis demonstrated that the CNAQ-J was constructed of one factor (appetite), yielding the SNAQ-JE, which includes four questions derived from the CNAQ-J. The three appetite instruments showed almost equivalent fitting to the model and reproducibility. The CNAQ-J and SNAQ-JE demonstrated satisfactory reliability and significant criterion-referenced/-related validity values, including BMIs, but the SNAQ-J included a low factor-loading item, exhibited less satisfactory reliability and had a non-significant relationship to BMI. The CNAQ-J and SNAQ-JE may be applied to assess the appetite of Japanese elderly, including persons with some cognitive impairment. Copyright © 2017 The Authors.

Purpose: To identify clinical factors associated with prostate cancer-specific mortality (PCSM), adjusting for comorbidity, in elderly men with intermediate-risk prostate cancer treated with brachytherapy alone or in conjunction with external beam radiation therapy. Methods and Materials: The study cohort comprised 1,978 men of median age 71 (interquartile range, 66-75) years with intermediate-risk disease (Gleason score 7, prostate-specific antigen (PSA) 20 ng/mL or less, tumor category T2c or less). Fine and Gray's multivariable competing risks regression was used to assess whether prevalent cardiovascular disease (CVD), age, treatment, year of brachytherapy, PSA level, or tumor category was associated with the risk ofmore » PCSM. Results: After a median follow-up of 3.2 (interquartile range, 1.7-5.4) years, the presence of CVD was significantly associated with a decreased risk of PCSM (adjusted hazard ratio, 0.20; 95% CI 0.04-0.99; p = 0.05), whereas an increasing PSA level was significantly associated with an increased risk of PCSM (adjusted hazard ratio 1.14; 95% CI 1.02-1.27; p = 0.02). In the absence of CVD, cumulative incidence estimates of PCSM were higher (p = 0.03) in men with PSA levels above as compared with the median PSA level (7.3 ng/mL) or less; however, in the setting of CVD there was no difference (p = 0.27) in these estimates stratified by the median PSA level (6.9 ng/mL). Conclusions: In elderly men with intermediate-risk prostate cancer, CVD status is a negative predictor of PCSM and affects the prognostic capacity of pretreatment PSA level. These observations support the potential utility of prerandomization stratification by comorbidity to more accurately assess prognostic factors and treatment effects within this population.« less

We investigated the associations between abnormal glucose tolerance and cognitive impairment in elderly subjects, taking into account some other known determinants of cognitive function. The study population consisted of community-living northern Finnish subjects aged 70 y or over (n=379, of whom were 141 men). Thirty-one percent of the men and women (n=43 for the men and n=75 for the women) scored 23 or less in the Mini Mental State Examination. A low level of basic education and high age were the most powerful predictors of impaired cognition. When adjusted for age, gender, educational level, presence of cardiovascular disease (or hypertension), use of alcohol, number of depressive symptoms and poor vision, abnormal glucose tolerance (including IGT) was also weakly associated with impaired cognitive function among these elderly subjects.

Background Knowledge of factors associated with the course of lower urinary tract symptoms (LUTS) before treatment is needed to inform preventive interventions. In a prospective study of elderly men untreated for LUTS, we identified factors associated with symptom progression and remission. Methods In community dwelling U.S. men age ≥ 65 years, the American Urological Association Symptom Index (AUA-SI) was repeated four times, once at baseline (2000–2002) and then every two years thereafter. Analyses included 1740 men with all four AUA-SI assessments, who remained free from diagnosed prostate cancer, and who reported no treatment for LUTS or benign prostatic hyperplasia (BPH) during follow-up that averaged 6.9 (±0.4) years. LUTS change was determined with group-based trajectory modeling of the repeated AUA-SI measures. Multivariable logistic regression was then used to determine the baseline factors associated with progressing compared to stable trajectories, and with remitting compared to progressing trajectories. Lifestyle, body mass index (BMI) (kg/m2), mobility, mental health (Short-Form 12), medical history, and prescription medications were considered for selection. Odds ratios (OR) and 95% confidence intervals (CI) were estimated for variables in each model. Results We identified 10 AUA-SI trajectories: four stable (1 277 men, 73%), three progressing (345 men, 20%), two remitting (98 men, 6%), and one mixed (20 men, 1%). Men in progressing compared to stable trajectories were more likely to have mobility limitations (OR=2.0, 95% CI: 1.0–3.8), poor mental health (OR=1.9, 95% CI: 1.1–3.4), BMI ≥ 25.0 kg/m2 (OR=1.7, 95% CI: 1.0–2.8), hypertension (OR=1.5, 95% CI: 1.0–2.4), and back pain (OR=1.5, 95% CI: 1.0–2.4). Men in remitting compared to progressing trajectories more often used central nervous system medications (OR=2.3, 95% CI: 1.1–4.9) and less often had a history of problem drinking (OR=0.4. 95% CI: 0.2–0.9).

The proportion of elderly in the population is increasing due to increased life expectancy and falling birth rate, and suicide rates increase with age. This study examined the following in England and Wales: (i) recent trends in the elderly suicide rate; (ii) recent trends in method-specific elderly suicide rate; (iii) the relationship between elderly population size and elderly suicide rate in recent years; and (iv) the sex difference in overall and method-specific elderly suicide rate. Data on the various suicide variables were ascertained from the annually published mortality data for years 1985 to 1996. The main findings of this study were: (i) there is a trend towards decline in the overall pure and combined suicide rates for elderly men and women over the 12 year study period; (ii) the main contributors to this decline are suicides due to poisoning by solid and liquid substances (E950), hanging, strangulation and suffocation (E953), drowning (E954), firearms and explosives (E955), and jumping from high places (E957); (iii) the overall pure and combined suicide rates and that for most categories of suicide was higher in men compared to women; and (iv) suicide rates decreased with an increase in the elderly population size. Suicide rates can decline due to a number of reasons. The challenge now is to ensure further decline in suicide rates to meet the Our Healthier Nations target.

Adenosine is an effective treatment for androgenetic alopecia (AGA) in Japanese men and women. Adenosine exerts its effects by significantly increasing the proportion of thick hair. In this study, we assessed the clinical outcome of adenosine treatment for 6 months in 38 Caucasian men. The change in proportion of thick hair (≥60 μm) compared with baseline in the adenosine group was significantly higher than that in the placebo group (P < 0.0001). The change in vellus hair proportion (<40 μm) was significantly lower in the adenosine group than that in the placebo group (P = 0.0154). The change in hair density compared with baseline of the adenosine group was also significantly higher compared with that of the placebo group (P = 0.0470). No adverse effects due to treatment were noted during this study by dermatological evaluation. Adenosine is effective in increasing the proportion of thick hair in Caucasian men with AGA as well as in Japanese men and women. © 2015 Japanese Dermatological Association.

Socioeconomic inequalities as social determinants of health are important issues in public health and health promotion. However, the association between socioeconomic status and eating behaviors has been investigated poorly in Japanese adults. To fill this gap, the present study examines the association of eating behaviors with household income and education. The sample comprised 3,137 Japanese adults (1,580 men and 1,557 women) aged 30 to 59 years who responded to an Internet-based cross-sectional survey in 2014. Data on the following eating behaviors were collected via self-report: "taking care of one's diet for health," "eating vegetables," "frequency of eating breakfast," "frequency of family breakfasts," "frequency of family dinners," "using the information on nutrition labels," and "conversations with family or friends during meals." Self-reported data on socioeconomic status (household income and education) and demographic variables (gender, age, district of residence, marital status, residence status, and employment status) were also collected. The associations between eating behaviors and household income or education were tested using binomial logistic regression analysis with eating behaviors as dependent variables and household income and education as independent variables. A trend P -value was calculated for three categories of household income (less than 3,000,000 JPY, 3,000,000-7,000,000 JPY, and over 7,000,000 JPY) and education (junior high/high school, 2-year college, and 4-year college/graduate school). Higher household income and education were significantly associated with higher rates of eating vegetables, using the information on nutrition labels, and conversation with family or friends during meals in Japanese men and women. Higher household incomes were significantly associated with lower rates of frequency of family breakfasts in Japanese men and lower rates of frequency of family dinners in Japanese men and women.

To describe the dietary intake of free-living, non-institutionalised, elderly people of Palma de Mallorca, and to evaluate their nutritional status and risk of undernutrition. Anthropometric and dietary survey (3-day food record), and risk of undernutrition (MNA-SF) were assessed in 230 (89 men and 141 women) free-living elderly people (average age 72.7 +/- 5.9 years) in Palma de Mallorca. Prevalence of undernutrition (1% in men and 5% in women), overweight (56% in men and 39% in women) and obesity (17% in men and 21% in women) were found. Mean daily energy intake (+/- SD) was 5.7 +/- 1.5 MJ in men and 5.3 +/- 1.3 MJ among women. The contribution of macronutrients to the total energy intake was different from the Recommended Intake for the elderly, since it was too derived from proteins, fats, SFA and sugars, but in only small amounts was derived from complex carbohydrates. Animal protein intake was two-thirds the total protein intake. Dietary fibre was low. Cholesterol/SFA ratio showed dietary risk of atherogenic potential. High percentages of elderly persons showed inadequate intake of calcium, magnesium, zinc, folic acid, vitamin D, and vitamin E. An increase in dietary complex carbohydrate and fibre, a decrease in fats, especially SFA, and a balanced intake of animal/vegetable proteins and fats are recommended. Dietary supplementation, especially with calcium, vitamin C and E, and occasionally vitamin D, may be useful to improve nutritional and health status of free-living elderly people in Palma de Mallorca.

Objective: This study aims to investigate the association of long-term weight-change slopes, weight fluctuation and the risk of type 2 diabetes mellitus (T2DM) in middle-aged Japanese men and women. Methods: A total of 4234 participants of Aichi Workers' Cohort Study who were aged 35–66 years and free of diabetes in 2002 were followed through 2014. Past body weights at the ages of 20, 25, 30, 40 years, and 5 years before baseline as well as measured body weight at baseline were regressed on the ages. Slope and root-mean-square-error of the regression line were obtained and used to represent the weight changes and the weight fluctuation, respectively. The associations of the weight-change slopes and the weight fluctuation with incident T2DM were estimated by Cox proportional hazards models. Results: During the median follow-up of 12.2 years, 400 incident cases of T2DM were documented. After adjustment for baseline overweight and other lifestyle covariates, the weight-change slopes were significantly associated with higher incidence of T2DM (hazard ratio (HR): 1.80, 95% confident interval (CI): 1.17–2.77 for men; and HR: 2.78, 95% CI: 1.07–7.23 for women), while the weight fluctuation was not (HR: 1.08, 95% CI: 1.00–1.18 for men and HR: 1.02, 95% CI: 0.84–1.25 for women). Conclusions: Regardless of the presence of overweight, the long-term weight-change slopes were significantly associated with the increased risk of T2DM; however, the weight fluctuation was not associated with the risk of T2DM in middle-aged Japanese men and women.

Neighbourhood green space, physical function and participation in physical activities among elderly men: the Caerphilly Prospective study

PubMed Central

2014-01-01

Background The built environment in which older people live plays an important role in promoting or inhibiting physical activity. Most work on this complex relationship between physical activity and the environment has excluded people with reduced physical function or ignored the difference between groups with different levels of physical function. This study aims to explore the role of neighbourhood green space in determining levels of participation in physical activity among elderly men with different levels of lower extremity physical function. Method Using data collected from the Caerphilly Prospective Study (CaPS) and green space data collected from high resolution Landmap true colour aerial photography, we first investigated the effect of the quantity of neighbourhood green space and the variation in neighbourhood vegetation on participation in physical activity for 1,010 men aged 66 and over in Caerphilly county borough, Wales, UK. Second, we explored whether neighbourhood green space affects groups with different levels of lower extremity physical function in different ways. Results Increasing percentage of green space within a 400 meters radius buffer around the home was significantly associated with more participation in physical activity after adjusting for lower extremity physical function, psychological distress, general health, car ownership, age group, marital status, social class, education level and other environmental factors (OR = 1.21, 95% CI 1.05, 1.41). A statistically significant interaction between the variation in neighbourhood vegetation and lower extremity physical function was observed (OR = 1.92, 95% CI 1.12, 3.28).

The built environment in which older people live plays an important role in promoting or inhibiting physical activity. Most work on this complex relationship between physical activity and the environment has excluded people with reduced physical function or ignored the difference between groups with different levels of physical function. This study aims to explore the role of neighbourhood green space in determining levels of participation in physical activity among elderly men with different levels of lower extremity physical function. Using data collected from the Caerphilly Prospective Study (CaPS) and green space data collected from high resolution Landmap true colour aerial photography, we first investigated the effect of the quantity of neighbourhood green space and the variation in neighbourhood vegetation on participation in physical activity for 1,010 men aged 66 and over in Caerphilly county borough, Wales, UK. Second, we explored whether neighbourhood green space affects groups with different levels of lower extremity physical function in different ways. Increasing percentage of green space within a 400 meters radius buffer around the home was significantly associated with more participation in physical activity after adjusting for lower extremity physical function, psychological distress, general health, car ownership, age group, marital status, social class, education level and other environmental factors (OR = 1.21, 95% CI 1.05, 1.41). A statistically significant interaction between the variation in neighbourhood vegetation and lower extremity physical function was observed (OR = 1.92, 95% CI 1.12, 3.28). Elderly men living in neighbourhoods with more green space have higher levels of participation in regular physical activity. The association between variation in neighbourhood vegetation and regular physical activity varied according to lower extremity physical function.

Pneumonia is a major cause of morbidity and mortality in elderly people, especially in those with chronic medical conditions such as chronic heart and lung diseases. We prospectively examined the effect of influenza and pneumococcal vaccinations on the rate of hospitalization for and complications of pneumonia, all respiratory tract conditions and mortality in elderly bedridden patients and found that both febrile days and pneumonia cases decreased. Thus, these results show that it is valuable to vaccinate for influenza elderly people even if they are confined to bed. Furthermore, the tuberculin skin test is an easy method to check the cell-mediated immunity in the elderly people. In the tuberculin skin test, all Japanese over 65 years old should have positive status. A negative result indicates depressed cell-mediated immunity. We undertook a trial to vaccinate tuberculin negative elderly people with BCG vaccine and found that the risk of pneumonia is decreased to a similar degree to that in subjects with positive tuberculin test results. We conclude that vaccination might be an effective strategy for the prevention of pneumonia in elderly people with limited activities of daily living.

Weight reduction improves glycemic control in obese men with glycated hemoglobin (HbA1c) of 5.6-6.4%, suggesting that it can prevent the development of diabetes in these patients. The aim of the present study was to quantify the amount of weight reduction necessary for minimization of diabetes risk in Japanese men with visceral fat accumulation. The study participants were 482 men with an estimated visceral fat area of ≥100 cm(2), HbA1c of 5.6-6.4%, fasting plasma glucose (FPG) of <126 mg/dL or casual plasma glucose <200 mg/dL. They were divided into two groups based on weight change at the end of the 3-year follow-up period (weight gain and weight loss groups). The weight loss group was classified into quartile subgroups (lowest group, 0 to <1.2%: second lowest group, ≥1.2 to <2.5%: second highest group, ≥2.5 to <4.3%: highest group, ≥4.3% weight loss). The development of diabetes at the end-point represented a rise in HbA1c to ≥6.5% or FPG ≥126 mg/dL, or casual plasma glucose ≥200 mg/dL. The cumulative incidence of diabetes at the end of the 3-year follow-up period was 16.2% in the weight gain group and 10.1% in the weight loss group (P not significant). The incidence of diabetes was significantly lower in the highest weight loss group (3.1%), but not in the second highest, the second lowest and the lowest weight loss groups (9.7, 10.1 and 18.3%), compared with the weight gain group. Minimization of the risk of diabetes in Japanese men with visceral fat accumulation requires a minimum of 4-5% weight loss in those with HbA1c of 5.6-6.4%.

There is an inverse association between educational level and body composition; however this association has strongly focused in young and adults population. The aim of this study was to analyze the educational levels attained in overweight and obesity Spanish elderly and to investigate if there was a correlation between having a low educational level and the risk of having overweight, central obesity or excess fat mass during the aging process. A representative sample of 2706 elderly (629 men and 2077 women; mean age of 72.1 ± 5.3 years) from Spain were assessed in the elderly EXERNET multi-center study between 2008 and 2009. Body composition was assessed in all subjects by bioelectrical impedance. ANCOVA was used to compare the averages between the groups. Logistic regression was used to calculate the association between educational level and the risk of having overweight, central fat or obesity. We observed significances between waist circumference and educational level in both sex (men 96.6 cm, women 86.3 cm); (p less than 0.05 and p less than 0.01, respective). There is an inverse association between the academic level, fat mass (29.5 kg) and percentage of body fat (40.8%) in women (p less than 0.05, p less than 0.01, respectively). No differences were observed in men. low educational level increases the possibility of having overweight or obesity in women and to have an increased waist circumference in both sexes.

The aim of this study was to investigate the relationship between plasma ghrelin levels and sarcopenia in elderly people. Cross-sectional study. Health consortium medical centers in the Maresme region, Barcelona (Spain). Two groups of subjects: persons ≥70 years (elderly group) and persons 25-65 years (young adults). Sarcopenia, diagnosed according to the EWGSOP definition, fasting and postprandial plasma ghrelin levels, body composition, hand grip, Barthel score, and frailty using Fried criteria. Fifty-five elderly subjects and 33 young adults were recruited. In both age groups, mean ghrelin levels were significantly higher in women than in men. However, mean ghrelin levels were similar in elderly and young men (716 vs. 752 pg mL-1, P = 0.763) as well as in elderly and young women (859 vs. 995 pg mL-1, P = 0.190). In the elderly group, subjects with sarcopenia showed significantly lower ghrelin levels than those without sarcopenia (650 vs. 899 pg mL-1, P = 0.036), but these differences disappeared when stratifying by gender. Elderly subjects without sarcopenia had the same ghrelin levels as young adults (899.3 vs. 899.6 pg mL-1). In young women, ghrelin levels correlated with fat free mass (rs = 0.58, P = 0.007) and muscular mass (rs = 0.54, P = 0.015) but these correlations were not observed in men nor in elderly women. This cross-sectional study does not allow a definitive conclusion about the relationship between ghrelin levels and sarcopenia. Further large prospective studies are needed to test this hypothesis.

Paying for the health and social care of the elderly.

The aging population of Japan is causing serious concern among social policymakers. The most urgent issue is to find a way to pay for the health and social care of the frail elderly. After universal coverage of pension and health insurance was achieved, but just before the economic growth rate was considerably slowed, in part, because of the oil crisis, the Japanese government more than doubled pension benefits and made medical care for the elderly free. Since the early 1980s, the government has tried hard to cut and control these benefits, only with moderate success. With a consumption tax rate of only 5%, rather than the proposed 7%, the government is now considering establishing a new health and social care insurance scheme for the elderly to finance the increasing cost of their care.

We examined the effects of the administration of docosahexaenoic acid (DHA)-enriched meals on cognitive function in the oldest elderly with cognitive impairment, such as dementia, living in nursing homes, and on the improvement in caregiver burden at aging agencies. Participants in elderly care facilities and nursing homes (n = 75; 88.5 ± 0.6 years) were randomized in active and placebo groups. The active group had family-style meals containing an additional 1720 mg of docosahexaenoic acid per day for 12 months. At baseline, and after 6 and 12 months of intervention, cognitive function was assessed using Hasegawa's Dementia Scale-Revised and the Mini-Mental State Examination; mental health condition was assessed with the Apathy scale and the Zung Self-Rating Depression Scale; caregiver burden was evaluated using Zarit Burden Interview scores; and participants' serum biochemical factors were measured. The participants were suggested to have dementia. After 12 months, the mean change in Mini-Mental State Examination subitem "Registration" score from baseline to month 12 showed a tendency to be greater in the active group than that in the placebo group. Mean changes in the Apathy scale from baseline to month 12 were less, and the changes in the Zung Self-Rating Depression Scale and the total Zarit Burden Interview scores showed a tendency to be lower in the active group than in the placebo group, respectively. These results suggest that docosahexaenoic acid-enriched meals protect against age-related cognitive decline, and also improve apathy and caregiver burden for the oldest-elderly Japanese with cognitive impairment, such as dementia.

Although high or low (no) meat consumption was associated with elevated or reduced mortality from cardiovascular disease, respectively, few studies have investigated the association between moderate meat consumption and cardiovascular disease. We aimed to evaluate the associations between moderate meat consumption and cardiovascular disease mortality. We conducted a prospective cohort study of 51,683 Japanese (20,466 men and 31,217 women) aged 40-79 years living in all of Japan (The Japan Collaborative Cohort Study; JACC Study). Consumptions of meat (beef, pork, poultry, liver and processed meat) were assessed via a food frequency questionnaire administrated at baseline survey. Hazard ratios (HRs) of mortality from cardiovascular disease were estimated from Cox proportional hazards regression models according to quintiles of meat consumption after adjustment for potential confounding variables. During 820,076 person-years of follow-up, we documented 2685 deaths due to total cardiovascular disease including 537 ischemic heart diseases and 1209 strokes. The multivariable HRs (95% confidence interval) for the highest versus lowest quintiles of meat consumption (77.6 versus 10.4 g/day) among men were 0.66 (0.45-0.97) for ischemic heart disease, 1.10 (0.84-1.43) for stroke and 1.00 (0.84-1.20) for total cardiovascular disease. The corresponding HRs (59.9 versus 7.5 g/day) among women were 1.22 (0.81-1.83), 0.91 (0.70-1.19) and 1.07 (0.90-1.28). The associations were similar when the consumptions of red meat, poultry, processed meat and liver were examined separately. Moderate meat consumption, up to ~100 g/day, was not associated with increased mortality from ischemic heart disease, stroke or total cardiovascular disease among either gender.

Daily life activity and the risk of developing hypertension in middle-aged Japanese men.

Although previous studies suggest that physical activity may reduce the risk of hypertension, the role of daily life activity in the development of hypertension remains unclear. The study population included 2548 Japanese male office workers aged 35 to 59 years, who were without hypertension (systolic blood pressure [SBP] <140 mm Hg, diastolic blood pressure [DBP] <90 mm Hg, and no medication for hypertension) and had no history of cardiovascular disease. Daily life energy expenditure was estimated by a 1-day activity record during an ordinary weekday at study entry. Blood pressures were measured at periodic annual health examinations over 7 successive years. After controlling for potential predictors of hypertension (age, family history of hypertension, alcohol consumption, cigarette smoking, regular physical exercise at entry, and change in body mass index during the follow-up period), mean SBP and DBP in each follow-up year decreased as daily life energy expenditure increased. With additional adjustment for SBP at entry, the relative risk of hypertension (SBP > or =140 mm Hg and/or DBP > or =90 mm Hg or medication for hypertension) across quartiles of daily life energy expenditure (lowest to highest) were 1.00, 0.84, 0.75, and 0.54 (P<.001 for trend). Analyses by presence or absence of a risk factor demonstrated that the risk of hypertension was inversely related to daily life energy expenditure in men at either low or high risk of hypertension. Daily life energy expenditure was also associated with reduced risk of hypertension for subjects in all 3 categories of normotension: low normal, normal, and high normal. Increased daily life activity is effective for the prevention of hypertension, and this benefit applies to men at either low or high risk of hypertension.

Elderly Koreans who consider suicide: Role of healthcare use and financial status.

This study investigated associations between the use of healthcare services and financial status and suicidal ideation (SI) in the past year among elderly people. Additionally, this study explored gender differences in such associations. Cross-sectional data of 1743 elderly people aged 65 years and above, who participated in the 2009 Korea National Health and Nutrition Examination Survey, were analyzed. The results showed that lack of preventive care and failure to obtain necessary healthcare services during the last 12 months had a significant effect on SI, especially among elderly women. Low financial status (i.e., receipt of National Basic Livelihood Security (NBLS) assistance) was significantly associated with SI among elderly men. The findings of this study emphasize the need for community-based suicide intervention services, especially for elderly men who receive NBLS and elderly women who do not undergo medical checkups and fail to obtain necessary medical services. Multiple intervention approaches, including the provision of community-based geriatric psychiatric services, improved social support, links with general hospital services, and local monitoring programs, are likely to be useful.

Beliefs in the paranormal were rated stronger in younger as compared to elderly adults by Emmons and Sobal in 1981, and sex correlates of paranormal beliefs appeared to be stronger in women than in men by Irwin in 1994. This research studied possible linkages between age and sex with a comparative analysis between results of Vitulli and Luper's 1998 survey among undergraduate students and data from elderly men (M = 72 yr., SD = 9.2, n = 21) and women (M = 69.3 yr., SD = 7.7, n = 55). Crawford and Christensen's 1995 12-item Extrasensory Perception Survey was administered to elderly persons living in apartment complexes and private homes, participating in activities in a recreation center, or attending a continuing-education seminar. A 2 x 2 multivariate analysis of variance from responses on the 12-item survey showed that undergraduate men and elderly women had the highest ratings on paranormal beliefs. The self-selecting characteristics of a segment of the elderly sample led to a post hoc univariate analysis of variance by partitioning that sample into those who were attending a continuing-education seminar versus all other elderly persons. Summated ratings (total scores) for this survey showed main effects for these subsamples and for sex. Sex and age differences were discussed in the context of the hypothesis of social marginality.

Somatotyping is an effective technique for the study of anthropometric variations and body composition in elderly subjects, even though it has not often been used in this field. The present study was conducted on a sample of 280 healthy Sardinians (134 men and 146 women) of age 60-89 years, subdivided into three age classes (60-69 years; 70-79 years; and 80-89 years). Somatotypes were computed according to Carter and Heath (Somatotyping-Development and Applications. Cambridge, England: Cambridge University Press; 1990). The results show a dominance of the endo- and mesomorphic components in the elderly subjects, with less development of ectomorphy than in younger individuals. In a comparison with other populations, our sample shows strong development of endomorphy and especially of mesomorphy, while ectomorphy values are generally low. Age-related variations are significant in both sexes and consist in a progressive reduction of the endomorphic component, particularly in the 80-89-year class (endomorphy in the three age classes: 6.4, 6.1, and 5.3 in men; 8.1, 7.8, and 6.8 in women). The mesomorphic component is characterized by stability (age variations: 6.4, 6.4, and 5.9 in men; 6.3, 6.4, and 6.3 in women) and the ectomorphic component by a slight increase (age variations: 0.5, 0.6, and 0.8 in men; 0.4, 0.3, and 0.5 in women). Sex differences are significant and especially large for the endomorphic component, with generally higher values in women. The sexual dimorphism tends to decrease with age. The results are discussed with regard to the biology of aging, with emphasis on the potential application of somatotype to studies of the elderly population. Copyright 2005 Wiley-Liss, Inc

Findings of past studies on the effect of drinking patterns on diabetes risk have been inconsistent. We aimed to investigate the role of drinking frequency and usual quantity consumed in the development of type 2 diabetes. Enrolled were 1650 Japanese men without diabetes (diabetes: fasting plasma glucose ≥7.0 mmol/L, glycated hemoglobin ≥6.5%, or self-reported clinician-diagnosed diabetes). Average alcohol consumption and 12 combinations of frequency and usual quantity per drinking occasion were assessed at the baseline examination. The absolute risk and HR for the development of diabetes were calculated. During a mean follow-up period of 10.2 y, 216 individuals developed diabetes. Lifetime abstainers (n = 153) had a relatively low incidence of diabetes (9.1/1000 person-years), similar to moderate consumers (99-160 g ethanol/wk; 9.0/1000 person-years). Increasingly higher quantities of alcohol usually consumed per occasion increased the risk of diabetes regardless of drinking frequency. The lowest incidence rate of diabetes (8.5/1000 person-years) was associated with the consumption of <1 drink (<23 g ethanol) per occasion over ≥6 times/wk. Binge drinking (≥3 drinks per occasion) significantly increased the risk of future diabetes regardless of frequency (HR: 1.79; 95% CI: 1.17, 2.74) compared with <1 drink per occasion. Among current drinkers, a drinking pattern of <1 drink per occasion regularly over 6 times within a week was associated with the lowest risk of developing diabetes. Usual quantity per drinking occasion was a more important determinant than was weekly drinking frequency in the association between alcohol consumption and risk of diabetes in Japanese men.

The link between long working hours and health has been extensively studied for decades. Despite global concern regarding metabolic syndrome, however, no studies to date have solely evaluated the relationship between long working hours and that syndrome. We therefore examined the association between long working hours and metabolic syndrome in a cross-sectional study. Between May and October 2009, we collected data from annual health checkups and questionnaires from employees at a manufacturing company in Shizuoka, Japan. Questionnaires were returned by 1,601 workers (response rate: 96.2%; 1,314 men, 287 women). After exclusions, including women because of a lack of overtime work, the analysis was performed for 933 men. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) for metabolic syndrome. Further, we conducted a stratified analysis by age-group (<40 years vs. ≥ 40 years). Metabolic syndrome was identified in 110 workers (11.8%). We observed a positive association between working hours and metabolic syndrome after adjusting for age, occupation, shift work, smoking status, frequency of alcohol consumption, and cohabiting status. Compared with subjects who worked 7-8 h/day, multivariate ORs for metabolic syndrome were 1.66 (95% CI, 0.91-3.01), 1.48 (95% CI, 0.75-2.90), and 2.32 (95% CI, 1.04-5.16) for those working 8-9 h/day, 9-10 h/day, and >10 h/day, respectively. Similar patterns were obtained when we excluded shift workers from the analysis. In age-stratified analysis, the corresponding ORs among workers aged ≥ 40 years were 2.02 (95% CI, 1.04-3.90), 1.21 (95% CI, 0.53-2.77), and 3.14 (95% CI, 1.24-7.95). In contrast, no clear association was found among workers aged <40 years. The present study suggests that 10 h/day may be a trigger level of working hours for increased risk of metabolic syndrome among Japanese male workers.

Dietary intakes of betaine and choline may reduce the risk of cardiovascular disease; however, epidemiologic evidence is limited. Seafood is a rich source of betaine and is a popular traditional food in Japan. We examined the associations of betaine and choline intakes with cardiovascular disease mortality in a population-based cohort study in Japan. Study subjects were 13,355 male and 15,724 female residents of Takayama City, Japan, who were aged ≥35 y and enrolled in 1992. Their diets were assessed by a validated food frequency questionnaire. Deaths from coronary heart disease and stroke were identified from death certificates over 16 y. Multivariable-adjusted HRs were computed by using Cox regression models. During follow-up, we documented 308 deaths from coronary heart disease and 676 deaths from stroke (393 from ischemic and 153 from hemorrhagic strokes). Compared with the lowest quartile, the second, third, and highest quartiles of betaine intake were significantly associated with a decreased risk of mortality from coronary heart disease in men after controlling for covariates. The HRs were 0.58 (95% CI: 0.36, 0.93), 0.62 (95% CI: 0.39, 0.998), and 0.60 (95% CI: 0.37, 0.97), respectively. The trend was not statistically significant (P = 0.08). There was no significant association between betaine intake and the risk of mortality from ischemic stroke. In women, betaine intake was unrelated risk of mortality from coronary heart disease and stroke (P = 0.32 and 0.73, respectively, for interaction by sex). There was no significant association between choline intake and cardiovascular disease mortality risk in men or women. Overall, we found no clear evidence of significant associations between choline and betaine intakes and cardiovascular disease mortality risk in Japanese men and women. © 2015 American Society for Nutrition.

The serum level of LOX-1 ligand containing ApoB (LAB) may reflect atherogenicity better than usual lipid parameters; however, the relationship between LAB and carotid intima-media thickness (IMT) was not clear even in Asian populations. A total of 992 community-dwelling Japanese men, aged 40 to 79 years, were enrolled in the present study. Serum LAB levels were measured by enzyme-linked immunosorbent assays (ELISAs) with recombinant LOX-1 and monoclonal anti-apolipoprotein B antibody. Serum LAB levels (median [interquartile range], μg cs/L) were 5341 μg cs/L (4093-7125). The mean average IMT of the common carotid artery was highest in the fourth LAB quartile (842 μm) compared with the first quartile (797 μm) after adjustment for age, high-density lipoprotein cholesterol, triglyceride, body mass index, hypertension, diabetes, high sensitivity C-reactive protein, smoking, and alcohol drinking. However, this statistically significant difference was lost after further adjustment for total cholesterol (TC). After stratification using the combination of median LAB and hypercholesterolemia (serum TC ≥ 6.21 mmol/L and/or lipid-lowering medication), the adjusted mean average IMT (standard error) in the high LAB/hypercholesterolemia group was 886 μm (12.7), 856 μm (16.7) in the low LAB/hypercholesterolemia group, and 833 μm (8.4) in the low LAB/normal cholesterol group (P = .004). After further adjustment for TC, mean average IMT in the high LAB group was significantly higher than that measured in the low LAB group in hypercholesterolemic participants not taking lipid-lowering medication. Serum LAB was associated with an increased carotid IMT in Japanese men, especially those with hypercholesterolemia. Copyright © 2016 National Lipid Association. Published by Elsevier Inc.

Objective While living overseas in another culture, retirees need to adapt to a new environment but often this causes difficulties, particularly among those elderly who require healthcare services. This study examines factors affecting healthcare service utilisation among Japanese retirees in Malaysia. Design We conducted 6 focus group discussions with Japanese retirees and interviewed 8 relevant medical services providers in-depth. Guided by the Andersen Healthcare Utilisation Model, we managed and analysed the data, using QSR NVivo 10 software and the directed content analysis method. Setting We interviewed participants at Japan Clubs and their offices. Participants 30 Japanese retirees who live in Kuala Lumpur and Ipoh, and 8 medical services providers. Results We identified health beliefs, medical symptoms and health insurance as the 3 most important themes, respectively, representing the 3 dimensions within the Andersen Healthcare Utilisation Model. Additionally, language barriers, voluntary health repatriation to Japan and psychological support were unique themes that influence healthcare service utilisation among Japanese retirees. Conclusions The healthcare service utilisation among Japanese retirees in Malaysia could be partially explained by the Andersen Healthcare Utilisation Model, together with some factors that were unique findings to this study. Healthcare service utilisation among Japanese retirees in Malaysia could be improved by alleviating negative health beliefs through awareness programmes for Japanese retirees about the healthcare systems and cultural aspects of medical care in Malaysia.

Inconsistent results have been found in prior studies investigating the accuracy of self-reported waist circumference, and no study has investigated the validity of self-reported waist circumference among Japanese individuals. This study used the diagnostic standard of metabolic syndrome to assess the accuracy of individual's self-reported height, weight and waist circumference in a Japanese sample. Study participants included 7,443 Japanese men and women aged 35-79 years. They participated in a cohort study's baseline survey between 2007 and 2011. Participants' height, weight and waist circumference were measured, and their body mass index was calculated. Self-reported values were collected through a questionnaire before the examination. Strong correlations between measured and self-reported values for height, weight and body mass index were detected. The correlation was lowest for waist circumference (men, 0.87; women, 0.73). Men significantly overestimated their waist circumference (mean difference, 0.8 cm), whereas women significantly underestimated theirs (mean difference, 5.1 cm). The sensitivity of self-reported waist circumference using the cut-off value of metabolic syndrome was 0.83 for men and 0.57 for women. Due to systematic and random errors, the accuracy of self-reported waist circumference was low. Therefore, waist circumference should be measured without relying on self-reported values, particularly in the case of women.

Background Metabolic syndrome has become a major worldwide public health problem. We examined the relationship between coffee consumption and the prevalence of metabolic syndrome among Japanese civil servants. Methods The study participants were 3284 employees (2335 men and 948 women) aged 20 to 65 years. Using data from their 2008 health checkup records, we analyzed the relationship between coffee consumption and the prevalence of metabolic syndrome. Metabolic syndrome was defined according to the Japanese criteria. Results Metabolic syndrome was diagnosed in 374 of the 2335 men (16.0%) and 32 of the 948 women (3.4%). In univariate and multiple logistic regression analyses, the odds ratios (ORs) among men for the presence of metabolic syndrome were 0.79 (95% CI: 0.56–1.03) and 0.61 (0.39–0.95), respectively, among moderate (≥4 cups of coffee per day) coffee drinkers as compared with non-coffee drinkers. Among all components of metabolic syndrome, high blood pressure and high triglyceride level were inversely associated with moderate coffee consumption in men, after adjusting for age, body mass index, smoking status, drinking status, and exercise. However, in women, moderate coffee consumption was not significantly associated with the prevalence of metabolic syndrome or its components. Conclusions Moderate coffee consumption was significantly associated with lower prevalence of metabolic syndrome in Japanese male civil servants. PMID:22343325

The Thinking About Life Experiences (TALE) Scale (Bluck & Alea, 2011) has three subscales that assess the self, social, and directive functions of autobiographical memory. This study constructs a Japanese version of the TALE Scale and examines its reliability and validity. Fifteen items that assess the three functions of autobiographical memory were translated into Japanese. We conducted an online investigation with 600 men and women between 20-59 years of age. In Study 1, exploratory and confirmatory factor analysis identified that the three-factor structure of the Japanese version of the TALE Scale was the same as the original TALE Scale. Sufficient internal consistency of the scale was found, and the construct validity of the scale was supported by correlation analysis. Study 2 confirmed that the test-retest reliabilities of the three subscales were sufficient. Thus, this Japanese version of the TALE Scale is useful to assess autobiographical memory functions in Japan.

Aims/Introduction Weight reduction improves glycemic control in obese men with glycated hemoglobin (HbA1c) of 5.6–6.4%, suggesting that it can prevent the development of diabetes in these patients. The aim of the present study was to quantify the amount of weight reduction necessary for minimization of diabetes risk in Japanese men with visceral fat accumulation. Materials and Methods The study participants were 482 men with an estimated visceral fat area of ≥100 cm2, HbA1c of 5.6–6.4%, fasting plasma glucose (FPG) of <126 mg/dL or casual plasma glucose <200 mg/dL. They were divided into two groups based on weight change at the end of the 3-year follow-up period (weight gain and weight loss groups). The weight loss group was classified into quartile subgroups (lowest group, 0 to <1.2%: second lowest group, ≥1.2 to <2.5%: second highest group, ≥2.5 to <4.3%: highest group, ≥4.3% weight loss). The development of diabetes at the end-point represented a rise in HbA1c to ≥6.5% or FPG ≥126 mg/dL, or casual plasma glucose ≥200 mg/dL. Results The cumulative incidence of diabetes at the end of the 3-year follow-up period was 16.2% in the weight gain group and 10.1% in the weight loss group (P not significant). The incidence of diabetes was significantly lower in the highest weight loss group (3.1%), but not in the second highest, the second lowest and the lowest weight loss groups (9.7, 10.1 and 18.3%), compared with the weight gain group. Conclusions Minimization of the risk of diabetes in Japanese men with visceral fat accumulation requires a minimum of 4–5% weight loss in those with HbA1c of 5.6–6.4%. PMID:26417413

Japanese-American (J-A) men who have immigrated to the U.S.A. and acquired the Western lifestyle usually have more invasive prostate cancer (PCa) than native Japanese (NJ) living in Japan. The specific reasons for these differences remain unknown. The objective of this study was to examine immunostainings of cathepsin B (CB) and its endogenous inhibitor stefin A (SA) in tissue microarray (TMA) and radical prostatectomy (RP) tissue sections in the hope of obtaining insights into the invasiveness of PCa in Japanese patients. TMA and RP sections were evaluated in 50 men (25 NJ and 25 J-A) for CB and SA reaction products. The CB and SA immunostainings were imaged directly from microscope slides to a computer using a high performance charge coupled device (CCD) digital camera, quantified using Metamorph software, analyzed using the two-sample t-test, and confirmed by multiple regression analysis. The CB and SA proteins were localized in the carcinomatous glands and isolated cancer cells in the TMA and RP sections. The Gleason scores and pre-surgery serum total prostate-specific antigen (PSA) levels did not differ significantly in the NJ and J-A patients (p = 0.14, p = 0.16, respectively). The Chi-square analysis of clinical stage versus place of birth showed that the NJ patients had significantly more T2a and T2b clinical stages than the J-A patients who had more advanced T2c and T3a stages (p = 0.003). The CB and SA immunostainings and their ratios in Gleason score 6 tumors did not show any difference, but the CB:SA ratios in score > or = 7 tumors approached significance levels. The overall matching of specimens according to the Gleason grade/score, pre-RP serum total PSA levels, clinical stage and age prior to evaluation of immunostainings greatly minimizes subjectivity associated with the evaluation of markers in this ethnic sub-population of PCa patients. CB and SA immunostaining is similar in Japanese patients who have organ-confined and moderately

The effects of 12-weeks of HMB ingestion and resistance training (RT) on abdominal adiposity were examined in 48 men (66-78 yrs). All participants were randomly assigned to 1 of 4 groups: no-training placebo (NT-PL), HMB only (NT-HMB), RT with PL (RT-PL), or HMB with RT (RT-HMB). DXA was used to estimate abdominal fat mass (AFM) by placing the region of interest over the L1-L4 region of the spine. Outcomes were assessed by ANCOVA, with Bonferroni-corrected pairwise comparisons. Baseline AFM values were used as the covariate. The ANCOVA indicated a significant difference (p = 0.013) between group means for the adjusted posttest AFM values (mean (kg) ± SE: NT-PL = 2.59 ± 0.06; NT-HMB = 2.59 ± 0.61; RT-PL = 2.59 ± 0.62; RT-HMB = 2.34 ± 0.61). The pairwise comparisons indicated that AFM following the intervention period in the RT-HMB group was significantly less than NT-PL (p = 0.013), NT-HMB (p = 0.011), and RT-PL (p = 0.010). These data suggested that HMB in combination with 12 weeks of RT decreased AFM in elderly men. Copyright © 2015. Published by Elsevier Inc.

Many reports have shown that vegetable intake is effective in inhibiting the onset and progression of diabetes mellitus, although the amount of vegetable intake required to be effective remains as unclear. The present study therefore aimed to clarify the relationship between the amount of vegetable intake and glycated hemoglobin A1c (HbA1c) and other metabolic parameters using male Japanese type 2 diabetic patients aged 65 years or older as subjects. Participants were 417 male type 2 diabetic patients aged 65 years or older enrolled in the Japanese Elderly Diabetes Intervention Trial. Dietary intakes were measured by using the Food Frequency Questionnaires method. The patients were divided into five groups by their daily total vegetable intake (A1: ~100 g, A2: 100~150 g, A3: 150~200 g, A4: 200~300 g, A5: 300 g~), and compared HbA1c and other metabolic parameters. Furthermore, the relationship between daily green vegetable intake and HbA1c and other metabolic parameters were examined among five groups divided by quintile methods. There were significant decreases in HbA1c, triglycerides and waist circumference with an increase of total vegetable intake. A significant decrease of HbA1c levels was observed in patients with a daily total vegetable intake of 150 g or more. Furthermore, there was a significant decrease of serum triglyceride levels in patients with a total vegetable intake of 200 g or more. HbA1c levels showed a decreasing tendency with the increase of green vegetable intake, and HbA1c levels in the Q1 group (green vegetable intake: less than 40 g) was significantly higher than those in the other four groups (anovaP = 0.025). In addition, there were significant decreases of body mass index, triglyceride levels and waist circumference with the increase of green vegetable intake. Triglyceride levels decreased significantly from the Q3 group (green vegetable intake: 70 g or more) to the Q5 group (green vegetable intake: 130 g or more; anovaP = 0.016). In the

Saito, M

1999-10-01

To investigate color and number preferences in Japan, 586 university undergraduates (239 men and 347 women; M age = 20.9 yr.) were asked to name a color (Question 1), to name their preferred color (Question 2), and to name their preferred number between zero and nine (Question 3). The results showed that Japanese students chose blue (33.5%) or red (26.0%) when asked to name a color but that red was not chosen as frequently as blue as a preferred color (red: 11.1%, blue: 37.1%). Sex differences were found on both Questions 1 and 2 by chi-squared test. Black was chosen more by men, while pink was selected more by women. 22.5% subjects also selected the number seven, supporting Simon's observation of the "blue-seven phenomenon." The reasons given for the choice showed that seven was "a lucky number" and "represented happiness" among Japanese students. Four colors (blue, red, white, and black) accounted for 76.8% and 65.1% of responses to Questions 1 and 2, respectively, and odd numbers 68.4% for Question 3.

To determine the relationship between denture wearing and nutritional status in the elderly with dementia. There could be a correlation between nutrition, oral health, dietary habits, patients' satisfaction, and their socio-economic status in the elderly, and the relationship between compromised oral status and nutritional status in the elderly with dementia. A 2-year follow-up study of 63 elderly Japanese women with and without dentures from a nursing home was undertaken to investigate their oral, physical and mental, and nutritional status. Each item for 2006 and 2008 in this study showed no significant difference between 2006 and 2008, except the calories/day. The elderly with dementia without complete dentures during the 2 years of the study only significantly decreased the mean of the calories/day. The calories/day of the elderly with dementia without dentures decreased after 2 years. Denture wearing for the elderly with dementia could be necessary to maintain a satisfactory intake of calories. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

Numerous studies have reported the association of cardiovascular risk factors with pulmonary embolism (PE), but the association of dietary factors, especially fish intake, with the risk of PE has not been fully established.Methods and Results:Using a prospective design, we studied the risk of PE mortality in relation to fish intake in 90,791 community-dwelling men and women in Japan aged 40-79 years. The hazard ratios (HRs) and 95% confidence intervals (CIs) for PE death were estimated using the Cox proportional hazards model. Compared with participants in the lowest fresh fish intake group (<1 time/month), the HRs (95% CIs) for PE death for those in the other intake groups were 0.35 (0.08-1.59) for 1-2 times/month, 0.19 (0.05-0.69) for 1-2 times/week, 0.20 (0.06-0.74) for 3-4 times/week, and 0.18 (0.05-0.66) for fish intake every day. In addition to these findings, compared with the participants in the lowest 10% of ω3 polyunsaturated fatty acid intake, those in the other groups had a 60-76% lower risk of PE death. Fresh fish intake, even 1-2 times/week, is associated with a lower risk of death from PE among Japanese men and women.

Background Anthropometric evaluation is an essential feature of geriatric nutritional evaluation for determining malnutrition, being overweight, obesity, muscular mass loss, fat mass gain and adipose tissue redistribution. Anthropometric indicators are used to evaluate the prognosis of chronic and acute diseases, and to guide medical intervention in the elderly. We evaluated anthropometric measurements and nutritional status as they relate to age and gender in healthy elderly people. Methods The study analyzed data from the national survey "Health needs and health service use by older-than-60-year-old beneficiaries of the Mexican Institute of Social Security (IMSS)". The present study included only individuals who reported no chronic disease in the last 20 years and had no hospital admission in the two months prior to the survey. Anthropometric measurements included weight, height, body mass index (BMI), body circumference (arm, waist, hip and calf), waist to hip ratio (WHR), elbow amplitude and knee-heel length. Results Application of the inclusion criteria resulted in a study population elderly of 1,968, representing 12.2% of the original number in the national survey in urban areas beneficiaries of the IMSS. The study population comprised 870 women and 1,098 men, with a mean age of 68.6 years. The average weights were 62.7 kg for women and 70.3 kg for men (p < 0.05), and the mean heights were 1.52 m for women and 1.63 m for men (p < 0.05). Age related changes in anthropometric values were identified. BMI values indicated that 62.3% of the population was overweight, and 73.6% of women and 16.5% of men had high fat tissue distribution. Conclusion Our findings suggest that applying the BMI thresholds that identify being overweight in the general adult population may lead to an overestimation in the number of overweight elderly Similar problems appear to exist when assessing waist circumference and WHR values. Prospective studies are required to determine the

To assess the relationship of weekly walking distance to percentiles of adiposity in elders (age {ge} 75 years), seniors (55 {le} age <75 years), middle-age men (35 {le} age <55 years), and younger men (18 {le} age <35 years old). Cross-sectional analyses of baseline questionnaires from 7,082 male participants of the National Walkers Health Study. The walkers BMIs were inversely and significantly associated with walking distance (kg/m{sup 2} per km/wk) in elders (slope {+-} SE: -0.032 {+-} 0.008), seniors (-0.045 {+-} 0.005), and middle-aged men (-0.037 {+-} 0.007), as were their waist circumferences (-0.091 {+-} 0.025, -0.045 {+-} 0.005, andmore » -0.091 {+-} 0.015 cm per km/wk, respectively), and these slopes remained significant when adjusted statistically for reported weekly servings of meat, fish, fruit, and alcohol. The declines in BMI associated with walking distance were greater at the higher than lower percentiles of the BMI distribution. Specifically, compared to the decline at the 10th BMI percentile, the decline in BMI at the 90th percentile was 5.1-fold greater in elders, 5.9-fold greater in seniors, and 6.7-fold greater in middle-age men. The declines in waist circumference associated with walking distance were also greater among men with broader waistlines. Exercise-induced weight loss (or self-selection) causes an inverse relationship between adiposity and walking distance in men 35 and older that is substantially greater among fatter men.« less

This study aims to evaluate whether the pattern of socioeconomic inequalities in physical and mental functioning as measured by the Short Form 36 (SF-36) differs among employees in Britain, Finland, and Japan and whether work characteristics contribute to some of the health inequalities. The participants were 7340 (5122 men and 2218 women) British employees, 2297 (1638 men and 659 women) Japanese employees, and 8164 (1649 men and 6515 women) Finnish employees. All the participants were civil servants aged 40–60 years. Both male and female low grade employees had poor physical functioning in all cohorts. British and Japanese male low grade employees tended to have poor mental functioning but the associations were significant only for Japanese men. No consistent employment-grade differences in mental functioning were observed among British and Japanese women. Among Finnish men and women, high grade employees had poor mental functioning. In all cohorts, high grade employees had high control, high demands and long work hours. The grade differences in poor physical functioning and disadvantaged work characteristics among non-manual workers were somewhat smaller in the Finnish cohort than in the British and Japanese cohorts. Low control, high demands, and both short and long work hours were associated with poor functioning. When work characteristics were adjusted for, the socioeconomic differences in poor functioning were mildly attenuated in men, but the differences increased slightly in women. This study reconfirms the generally observed pattern of socioeconomic inequalities in health for physical functioning but not for mental functioning. The role of work characteristics in the relationship between socioeconomic status and health differed between men and women but was modest overall. We suggest that these differences in the pattern and magnitude of grade differences in work characteristics and health among the 3 cohorts may be attributable to the different welfare
