Gender Differences in the Association between Psychological Distress and Sociability among Older Adult Survivors: Cross-Sectional Survey Four Years after the 2016 Kumamoto Earthquake in Japan.

Mental health deterioration after a disaster is a concern. Individuals' sociability is expected to relate to the risk of this deterioration; however, research focusing on older adults is lacking. We aimed to investigate the relationship between psychological distress and sociability in older adults who survived the 2016 Kumamoto earthquake. We conducted a self-reported questionnaire survey in 2020. Data on 3,588 people aged 65 years and over (2,024 women and 1,564 men, mean age 74.6 ± 7.2, mean ± standard deviation) were analyzed. The overall prevalence of psychological distress (the Kessler psychological distress scale: K6 ≧ 10) was 10.5%; by gender, it was 11.2% in women and 9.5% in men. Logistic regression analysis revealed that, in the total sample, age, gender, public housing, reduction in income resulting from the coronavirus disease 2019 pandemic, self-rated unhealthy conditions, subjective social isolation, and a lack of awareness of community events were positively associated with psychological distress. For women, a lack of community participation was positively related to psychological distress. For men, not knowing the change in school district after relocation was negatively associated with psychological distress, probably due to men's scarce community participation and reliance on friendships, compared to women's stronger dependence on community. Moreover, having a family member or friend to consult with was associated with a lower risk of psychological distress, regardless of gender. Gender differences were related to different conditions of social participation and types of social relationships. Enhancing community participation and family relationships among women and social contact with friends among men is essential.

Meaning of community activity participation for older adults in couple households.

Objective: Currently, 65.3% of older adults in Japan live in couple households. If one partner dies, the other may be unable to reconstruct their lifestyles, have health problems, or become isolated. Participation in community activities helps them maintain physical, mental, and social health. This study aimed to clarify the meaning of participation in community activities among older adults in couple households. Methods: Semi-structured individual interviews were used to collect data. In February 2019, six adults aged 65 and above who had lived with their spouses for at least one year and continuously participated in community activities were interviewed in Miyazaki City, Japan. Data were analyzed using the KJ method (a qualitative method that organizes ideas in a bottom-up fashion developed by Kawakita Jiro), supervised by a professional instructor. Results: The results revealed seven symbols using this method: 1) building a cooperative relationship with a spouse: respect the willingness to work hard for members; 2) consideration for relationships with other organizations: pay attention to every detail; 3) proactive attitude: don't leave everything to others, 4) attitude of questioning one's way of being: myself in connection to others, 5) connection among participants: increased awareness directed toward others, 6) spiritual fulfillment: time, place, and opportunity for outings, 7) physical and mental self-control for continued community activities: growing awareness of health care. Conclusions: For older adults in couple households, it is found that participation in community activities helps them receive support from their spouses and gain a proactive attitude, and the connection between participants contributes to physical and mental control and also improves their health.

Factors Related to Physical Activity among Older Adults Who Relocated to a New Community after the Kumamoto Earthquake: A Study from the Viewpoint of Social Capital.

Previous studies have shown an association between social capital and physical activity in older adults. Older adults who relocated after the Kumamoto earthquake may become physically inactive, and the extent of this inactivity may be buffered by social capital. Accordingly, this study applied the social capital perspective to examine factors that affect the physical activity of older adults who relocated to a new community after the Kumamoto earthquake. We conducted a self-administered mail questionnaire survey with 1494 (613 male, 881 female, mean age 75.12 ± 7.41 years) evacuees from temporary housing in Kumamoto City, aged 65 years and above, who relocated to a new community after the earthquake. We performed a binomial logistic regression to examine the factors affecting participants' physical activity. The results showed that physical inactivity (decreased opportunities for physical activity, decreased walking speed, and no exercise habits) was significantly associated with non-participation in community activities, lack of information about community activities, and being aged 75 years and over. Lack of social support from friends was significantly associated with lack of exercise habits. These findings encourage participation in community activities, alongside giving and receiving social support in health activities that target older adults who relocated to new communities after the earthquake.

Depression, Insomnia, and Probable Post-Traumatic Stress Disorder among Survivors of the 2016 Kumamoto Earthquake and Related Factors during the Recovery Period Amidst the COVID-19 Pandemic.

The aftereffects of the severe 2016 Kumamoto earthquake were complicated by the COVID-19 pandemic. This study aimed to identify mental health problems and related factors among survivors five years after the earthquake and clarify its long-term effects. A cross-sectional survey was conducted in 2020 among 19,212 survivors affected by the earthquake who moved from temporary to permanent housing. We analysed 8966 respondents (5135 women, 3831 men; mean age 62.25 ± 17.29 years). Logistic regression analysis was conducted to examine associations between mental health problems and socioeconomic factors. Prevalence rates of psychological distress, insomnia, and probable post-traumatic stress disorder were 11.9%, 35.2%, and 4.1%, respectively. Female gender (OR = 1.33, 95% CI = 1.13-1.57; OR = 1.21, 95% CI = 1.08-1.34; OR = 1.81, 95% CI = 1.41-2.32), public housing (OR = 2.14, 95% CI = 1.63-2.83; OR = 1.54, 95% CI = 1.26-1.88; OR = 2.41, 95% CI = 1.62-3.58), loneliness (OR = 9.08, 95% CI = 7.71-10.70; OR = 5.55, 95% CI = 4.90-6.30; OR = 3.52, 95% CI = 2.77-4.49), COVID-19-induced activity reduction (OR = 1.41, 95% CI = 1.19-1.66; OR = 1.86, 95% CI = 1.68-2.07; OR = 1.80, 95% CI = 1.40-2.31), and COVID-19-induced income reduction (OR = 1.33, 95% CI = 1.12-1.57; OR = 1.43, 95% CI = 1.28-1.59; OR = 1.92, 95% CI = 1.51-2.43) were significantly associated with mental health problems. These results suggest that gender, current housing, loneliness, and COVID-19 affected the survivors' mental health during recovery.
