    BACKGROUND: Second-hand smoke exposure has been associated with poor mental health. However, among Japanese adults, little is known about the association between second-hand smoking and depressive symptoms. We examined this association in a cross-sectional study among a Japanese general adult population sample. METHODS: Japanese adults were recruited from the Japan Multi-Institutional Collaborative Cohort Study in the Okazaki area between 2012 and 2017. Second-hand smoke exposure and smoking status were assessed using a self-administered questionnaire. Based on their frequency of exposure to second-hand smoke, non-smokers and smokers were categorized as "almost never," "sometimes," and "almost every day". Depressive symptoms were defined by a Kessler 6 score ≥5 points. We performed a multivariable Poisson regression analysis to obtain adjusted prevalence ratios (PRs) and 95% confidence intervals (CIs) for depressive symptoms. RESULTS: Overall, 5,121 participants (4,547 non-smokers and 574 smokers) were included whose mean age was 63.6 (standard deviation [SD], 10.3) years for non-smokers and 59.33 (SD, 10.2) years for smokers. The association between second-hand smoking and depressive symptoms was significant among non-smokers, but not among smokers. Among non-smokers, PRs compared with "almost never" were 1.25 (95% CI, 1.09-1.42) for "sometimes" and 1.41 (95% CI, 1.09-1.84) for "almost every day" (P for trend <0.001); among smokers, PRs compared with "almost never" were 1.30 (95% CI, 0.82-2.06) for "sometimes" and 1.44 (95% CI, 0.90-2.33) for "almost every day" (P for trend = 0.144). CONCLUSIONS: Second-hand smoking and depressive symptoms were associated among non-smokers. Our findings indicate the importance of tobacco smoke control for mental health.

    Objectives: Family caregiver burden is associated with higher psychological distress. However, little is known about the impact of neighbourhood relationships on caregivers’ psychological distress. We examined whether neighbourhood relationships of caregivers moderate the association between family caregiver burden and psychological distress. Study design: This was a cross-sectional study. Methods: We recruited 5321 Japanese adults who participated in the Japan Multi-Institutional Collaborative Cohort Study in the Okazaki area between 2013 and 2017. Participants completed self-reported questionnaires to measure psychological distress (Kessler 6: K6), subjective caregiver burden, and neighbourhood relationships. We performed a multivariable linear regression analysis in which caregiver burden was designated as an independent variable and the K6 score as a dependent variable, adjusting for demographics. The interaction term between caregiver burden and neighbourhood relationships was also included in the analysis. Results: Data from a total of 5069 participants were included (mean age [standard deviation]: 63.1 years [10.3 years]; 2226 [43.9%] female). Caregiver burden was significantly and positively associated with psychological distress (compared with no burden, mild burden: β = 0.24, P = 0.197; severe burden: β = 0.60, P < 0.01; P for trend < 0.01). There was a significant negative interaction effect of caregiver burden × neighbourhood relationship on psychological distress (severe burden × good neighbourhood relationship: β = −3.29, P < 0.01). Conclusions: A higher caregiver burden was associated with higher psychological distress, and neighbourhood relationships moderated this association. Our findings suggest that good neighbourhood relationships can buffer caregiving-associated psychological distress.

    We examined the association between family caregiver burden and subjective well-being with social participation's moderating effect among Japanese adults. Data were obtained from a cross-sectional survey by the Japan Multi-Institutional Collaborative Cohort Study in the Okazaki area between 2013 and 2017. Study participants included 5321 adults who visited the Public Health Center for annual health check-ups and answered a questionnaire regarding health status and lifestyle. Subjective well-being was assessed by a single item, out of 10 points, and analyzed with multivariable linear regression analysis models by subjective family caregiver burden ("none", "mild", "severe"), stratified by gender. Ultimately, 2857 men and 2223 women were included. Mean participant age (standard deviation) in years was 64.7 (10.4) for men and 61.3 (10.0) for women. Multivariable analysis revealed that, among women, higher caregiver burden was inversely associated with subjective well-being (p for trend < 0.001), and the interaction of severe caregiver burden and social participation on subjective well-being was positive and significant (p for interaction < 0.05). High family caregiver burden was inversely associated with subjective well-being among Japanese women, but moderated by the caregiver's social participation, suggesting the importance of community development that enables family caregivers' social participation to protect their subjective well-being.

    OBJECTIVE: We aimed to examine missing data in FFQ and to assess the effects on estimating dietary intake by comparing between multiple imputation and zero imputation. DESIGN: We used data from the Okazaki Japan Multi-Institutional Collaborative Cohort (J-MICC) study. A self-administered questionnaire including an FFQ was implemented at baseline (FFQ1) and 5-year follow-up (FFQ2). Missing values in FFQ2 were replaced by corresponding FFQ1 values, multiple imputation and zero imputation. SETTING: A methodological sub-study of the Okazaki J-MICC study.ParticipantsOf a total of 7585 men and women aged 35-79 years at baseline, we analysed data for 5120 participants who answered all items in FFQ1 and at least 50% of items in FFQ2. RESULTS: Among 5120 participants, the proportion of missing data was 3·7%. The increasing number of missing food items in FFQ2 varied with personal characteristics. Missing food items not eaten often in FFQ2 were likely to represent zero intake in FFQ1. Most food items showed that the observed proportion of zero intake was likely to be similar to the probability that the missing value is zero intake. Compared with FFQ1 values, multiple imputation had smaller differences of total energy and nutrient estimates, except for alcohol, than zero imputation. CONCLUSIONS: Our results indicate that missing values due to zero intake, namely missing not at random, in FFQ can be predicted reasonably well from observed data. Multiple imputation performed better than zero imputation for most nutrients and may be applied to FFQ data when missing is low.

    BACKGROUND: It is known that physical activity affects glucose metabolism. However, there have been no reports on the influence of physical activity earlier in life on subsequent glucose metabolism. Therefore, we analyzed the influence of physical activity in earlier decades of life on insulin resistance in middle aged and older residents in Japan. METHODS: The subjects were 6,883 residents of Okazaki City between the ages of 40 and 79 years who underwent physical examinations at the Okazaki City Medical Association Public Health Center from April 2007 through August 2011. They gave informed consent for participation in the study. Data on individual characteristics were collected via a questionnaire and from the health examination records. Fasting blood glucose and insulin levels were used to calculate the homeostatic model assessment of insulin resistance (HOMA-IR). HOMA-IR >1.6 was considered to indicate insulin resistance for the purpose of logistic regression models. RESULTS: The study sample included 3,683 men and 3,200 women for whom complete information was available. For those who exercised regularly throughout their teens to their 30s-40s, the odds ratio for having insulin resistance was 0.75 (95% confidence interval [CI], 0.58-0.96) for men and 0.76 (95% CI, 0.58-0.99) for women after adjusting for other variables, including age, body mass index, and present physical activity. A linear trend was also observed in both men and women. CONCLUSIONS: Subjects who have exercised regularly in the early decades of life are less likely to have insulin resistance later in life.
