男性更年期障害(Late-Onset Hypogonadism:LOH)は,加齢やストレスによるテストステロン低下が原因で,倦怠感や性欲低下,不眠などの身体的・心理的・性的症状を引き起こす。生活習慣や心理社会的要因が症状の発症や悪化に関連していると言われているが,本邦での疫序研究は十分ではない。我々は,日本人男性1,500名を対象に更年期症状の影響要因を調査するコホート研究等を展開する研究プロジェクトを立ち上げた。2024年9月のベースライン調査では,約80%がLOHを認知していたが,その内容を理解している者は17%にとどまり,症状自覚者の医療機関受診者割合は重度の者でさえ18%にとどまった。この結果,LOHに関する情報普及や受診行動を促進する支援の必要性を示している。本研究は,LOH予防や進行抑制に役立つエビデンスを提供し,男性の健康寿命延伸と生活の質向上を目指している。(著者抄録)

AIM: Maintaining ≥20 teeth is a public health goal worldwide. Healthy aging, which includes psychological and social well-being, as well as physical indicators, has attracted a great deal of attention with the progression of aging societies. However, no studies have examined the association between the number of remaining teeth and healthy aging. This study aimed to investigate the association between the number of remaining teeth and healthy aging. METHODS: This community-based longitudinal cohort study included 8300 Japanese people aged ≥65 years who were free of disability and depression in the baseline survey in 2006. The participants were categorized into four groups according to the number of remaining teeth at baseline: 0-9, 10-19, 20-24 and ≥25. The primary outcome was healthy aging (defined as meeting all four of the following criteria: free of disability, free of depression, high health-related quality of life and high life satisfaction), as assessed by a questionnaire survey carried out in 2017. Multiple logistic regression was used to calculate the corresponding odds ratios and 95% confidence intervals. RESULTS: During about 11 years of follow-up, 621 (7.5%) participants attained healthy aging. Participants with ≥20 remaining teeth showed a higher healthy aging rate. Compared with participants with 0-9 teeth, the multivariate-adjusted odds ratios (95% confidence intervals) for 10-19, 20-24 and ≥25 teeth were 0.98 (0.77-1.26), 1.28 (1.01-1.63) and 1.59 (1.24-2.03), respectively. CONCLUSIONS: These findings suggest that maintaining ≥20 teeth was associated with healthy aging. Geriatr Gerontol Int 2021; ••: ••-••.

Journals of Gerontology - Series A Biological Sciences and Medical Sciences ( Journals of Gerontology - Series A Biological Sciences and Medical Sciences ) 77 ( 1 ) 106 - 113 2022年01月

BACKGROUND: Our study examined the association between social participation and healthy aging using a community-based cohort study among Japanese elderly. METHODS: This prospective study was conducted in Ohsaki City, Japan, and included 7,226 subjects aged ≥65 years at the baseline survey in 2006. We obtained information on frequency of participation in three types of community activities (i.e. neighborhood activities, hobbies, and volunteer activities) at baseline. Exposure was measured by the number of types of community activities participated in and subjects were categorized into four groups (i.e. none, one type, two types, and three types). The primary outcome was healthy aging as assessed by a questionnaire survey conducted in 2017, and was defined as meeting the following four criteria: free of disability, free of depression, high health-related quality of life, and high life satisfaction. We used multiple logistic regression models to calculate the corresponding odds ratios (ORs) and 95% confidence intervals (95%CIs). RESULTS: During 11 years of follow-up, 574 (7.9%) subjects attained healthy aging. Compared with subjects not participating in any activity, the multivariable-adjusted ORs (95%CIs) were 1.90 (1.40, 2.59) for those participating in one type, 2.49 (1.84, 3.38) for two types, and 3.06 (2.30, 4.07) for three types (P for trend <.0001). Furthermore, for each type of community activity, a higher frequency of participation was related to higher probability of healthy aging. CONCLUSIONS: Our study suggests that social participation is associated with the promotion of healthy aging, and that the benefits were observed across different types of community activities.

BACKGROUND: We previously reported that psychological distress was associated with an increased risk of functional disability. However, the mechanism of the association remains unclear. Our aim was to estimate the mediating effect of lifestyle and bodily pain on the association among elderly survivors after the Great East Japan Earthquake. METHODS: The study population comprised 1037 residents aged ≥ 65 years. The baseline surveys (exposure and mediators) were conducted in 2011. We classified participants into three categories according to their Kessler 6 score (low: 0-9, moderate: 10-12, and high: 13-24) and defined functional disability as certification for long-term care insurance in Japan. The Cox proportional hazards model was used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) for incident functional disability according to Kessler 6 categories and explored the mediating effects of lifestyle and bodily pain on the association. RESULTS: During approximately 8 years of follow-up, we documented 271 incident cases of functional disability. Compared with those in the low distress group, the multivariate adjusted HR for incident functional disability was 1.95 (95% CI 1.21-3.13) for those in the high distress group. Time spent walking, going out, and bodily pain significantly mediated the association between psychological distress and incident functional disability by 10.2%, 10.5%, and 10.3% for the high distress group, respectively. LIMITATIONS: We did not consider unmeasured confounders and use of appropriate medication. CONCLUSIONS: The evaluation and treatment of bodily pain as well as promotion of active lifestyle would be important for preventing disability among disaster survivors.

Little is known about psychological distress and its associated factors during the COVID-19 pandemic among nursing students, especially during the initial spread. The present study aimed to investigate the prevalence of psychological distress among Japanese nursing students after the first semester of 2020 with shifted classes and practice online. Furthermore, we examined whether factors such as health issues and resilience were associated with psychological distress. The data were obtained from a cross-sectional, self-administered questionnaire survey at a Japanese nursing college from September to November 2020 (n = 289). We collected data such as sociodemographic variables, medical history, insomnia, and resilience (Bidimensional Resilience Scale). Psychological distress was measured using the K6 scale (scores ≥ 5). The prevalence of psychological distress was 58.5%. The multivariate Poisson regression analysis found a negative association between innate resilience factors, and positive associations between medical history, insomnia, and psychological distress. The present study showed that more than half of the study participants experienced high levels of psychological distress. Our results suggest the importance of monitoring mental health among nursing students, focusing not only on health issues, but also personality components such as innate resilience during the prolonged COVID-19 pandemic.

OBJECTIVE: The aim of this study was to investigate the effect of a financial incentive on the number of daily walking steps among community-dwelling adults in Japan. STUDY DESIGN: Two-arm, parallel-group randomised controlled trial. SETTING/PARTICIPANTS: We recruited physically inactive community-dwelling adults from Sendai city, Japan. Eligible participants were randomly allocated to an intervention or a wait list control group. Pedometers were used to assess the mean number of daily steps in three periods: baseline (weeks 1-3), intervention (weeks 4-6) and follow-up (weeks 7-9). INTERVENTION: The intervention group was offered a financial incentive (shopping points) to meet the target number of increased daily steps in the intervention period. MAIN OUTCOME MEASURES: The primary outcome was an increase in the mean number of daily steps in the intervention and follow-up periods compared with baseline. RESULTS: Seventy-two participants (69.4% women; mean age, 61.2±16.2 years; mean number of daily steps at baseline, 6364±2804) were randomised to the intervention (n=36) and control groups (n=36). During the intervention period, the increase in mean daily steps was significantly higher in the intervention group (1650, 95% CI=1182 to 2119) than in the control group (514, 95% CI=136 to 891; p<0.001). However, the difference between groups was not significant at follow-up after the incentives were removed (p=0.311). In addition, compared with controls, a significantly higher proportion of participants in the intervention group showed an increase in mean daily steps of ≥1000 (69.4% vs 30.6%, respectively; OR=5.17, 95% CI=1.89 to 14.08). There were no adverse effects from the intervention. CONCLUSIONS: The present results suggest that financial incentives are effective in promoting short-term increases in physical activity.

OBJECTIVE: Personality traits have been associated with an increased risk of cardiovascular disease (CVD) mortality as well as life-style-related cardiovascular risk factors. However, the mediating effects of life-style behaviors in the association between personality factors and CVD mortality remain insufficiently understood. The aim of the present study was to examine the mediating effect of life-style behaviors on the association between personality traits and CVD mortality. METHODS: We conducted a prospective cohort study of 29,766 Japanese adults aged 40 to 64 years at the baseline and followed them up for 20.8 years from 1990 to 2011. Personality was measured using the Japanese version of the Eysenck Personality Questionnaire - Revised Short Form in 1990. We estimated the multivariable hazard ratio and 95% confidence interval for CVD mortality using Cox proportional hazards models, and explored the mediating effects of life-style behaviors (smoking, drinking, body mass index, and time spent walking) on the association between personality traits and CVD mortality. RESULTS: We documented 1033 deaths due to CVD during 562,446 person-years of follow-up. Psychoticism represents tough-mindedness, aggressiveness, coldness, a lack of deliberateness, and egocentricity. After adjusting for confounding variables, higher psychoticism was associated with CVD mortality (base model hazard ratio = 1.36, 95% confidence interval = 1.14-1.61, p trend < .001). All the life-style behaviors together mediated this association by 19.2%, with smoking having the greatest effect at 15.7%. For the other personality traits, no significant associations with CVD mortality were found. CONCLUSION: The present study demonstrated that life-style behaviors, especially smoking, partially mediate the association between psychoticism and CVD mortality.

<p>With population aging, an increasing attention has been paid to quality of life rather than mere longevity. Now, it is urgently needed to clarify predictors of well-being in later life, i.e., “successful aging (SA).” The aim of this study is to investigate whether the number of remaining teeth impacts on maintenance of SA among Japanese older people. The present study was conducted in Tsurugaya district, a suburban area of Sendai, in northern Japan, and included older people aged ≥ 70 years who had met the criteria for SA at a 2003 baseline survey. At the baseline survey, dentists obtained data for the number of remaining teeth. We obtained information about Long-term Care Insurance certification, including the dates of incident functional disability and death between 2003 and 2012. Data pertaining to health-related quality of life (HRQOL) were collected at the 2003 baseline survey and the 2012 follow-up survey. Maintenance of SA was defined in terms of survival, disability-free status and high HRQOL in both 2003 and 2012. Among 450 participants, 108 (24.0%) were considered to have maintained a state of SA. When participants were classified into three groups according to previous studies, in comparison with participants who retained 0-9 teeth, the multivariate prevalence ratios (95% confidence intervals) were 1.39 (0.81-2.36) for those who retained 10-19 teeth and 1.58 (1.002-2.50) for those who retained ≥ 20 teeth (p trend = 0.046). The present results suggest that retaining ≥ 20 teeth is associated with maintenance of SA among Japanese older people.</p>
