Gender Differences in Suicide Rates of Municipalities in South Korea.

Background: South Korea showed the highest suicide rate among the countries in the Organization for Economic Cooperation and Development. Aims: This study aimed to discern the profiles of municipalities according to their suicide rates across the life cycle and gender, and then to identify the unique characteristics of each latent group. Method: This study applied a latent profile modeling to categorize the regions by life cycle suicide rates of their residents. The latent profile analysis (LPA) yielded four latent groups for males and three groups for females. This study explored the unique characteristics of 250 municipalities by latent groups with these groups. Results: The results suggested significant gender differences in the characteristics of localities. For the high adolescent suicide rates groups, there was a higher proportion of urban areas among males while there was a higher proportion of rural regions among females. Limitations: This study analyzed secondary data of municipalities, so the characteristics of each profile of suicide rate could only be identified within this existing data. Conclusions: This paper is one of the first studies to apply the LPA to different latent profiles by life cycle suicide rates.

Relationships Between Perceived Neighborhood Disorder and Depressive Symptomatology: The Stress Buffering Effects of Social Support Among Older Adults.

Existing research indicates neighborhood is an important determinant of depressive symptoms. However, this research has several limitations. These include a lack of investigation of older adults' experiences and of social support as a possible moderator. The current study aims to fill these gaps by increasing knowledge about the relationships between perceived neighborhood disorder and depressive symptoms among older adults. Applying stress process theory, this study investigated the relationships between two subjective indicators of neighborhood stressors - physical and social perceived neighborhood disorder and depressive symptoms. This study also tested whether social support moderated the effects of the neighborhood stressors on depressive symptoms. This study was based on secondary data analysis from the Health and Retirement Study 2016 (N = 3,684; age 50+). This study applied a negative binomial regression in that the outcome was a count variable. The results showed the stress buffering effects of social support were not significant for both perceived neighborhood social disorder and physical disorder. Not as a moderator but as the main effect, lower social support was significantly related to higher depressive symptoms. Having a depression history, lower self-rated health, female, and lower education were also related to higher depressive symptoms. This study contributes to social work practice by addressing older adults' depressive symptomatology. Findings identified vulnerable older adults to target for interventions based on individual characteristics. Focusing on social support should be a vital component of interventions. Social workers can help older adults maintain and strengthen their social support, with beneficial effects on their depressive symptomatology.

Social Support and Depressive Symptoms among Trauma-Impacted Older Adults.

Purpose: The present study investigates the association between social support and depressive symptomatology among older adults who have been impacted by trauma. Previous studies have not sufficiently explored this topic to date.Method: The current study analyzed public-use data from the 2012 Health and Retirement Study (N = 4,195), focusing specifically on community-dwelling older adults (> 50). They had at least one traumatic event in their lifetime.Results: This study found that higher levels of social support were significantly associated with lower levels of depressive symptoms after controlling for life satisfaction, age, gender, race, ethnicity, and education..Discussion and Conclusion: The recent emergence of trauma-informed research has consistently emphasized the importance of social interaction for mental health. The current study shows that social support can reduce depressive symptoms of those who have experienced trauma.

Depressive Symptoms and Multimorbidity: Is There an Association for Older Black Americans?

Objectives: Many existing studies have reported a higher prevalence of depressive symptoms among older Black Americans. They also experience a disproportionate burden of multimorbidity, the presence of multiple chronic conditions. Therefore, this study was to identify the association between depressive symptomatology and multimorbidity among older Black Americans. Methods: This study analyzed the 2014 Health and Retirement Study (N = 1206). A negative binomial regression was applied to assess the association between multimorbidity and depressive symptomatology. Results: Higher levels of chronic health problems were associated with higher levels of depressive symptomatology among older Black Americans (Incidence rate ratio = 1.093; p = .002). Lower self-reported health, lower income, and lower educational attainment were also related to higher depressive symptoms. Discussion: Older Black Americans experience vulnerability on multiple levels, and shouldering additional psychosocial and financial burdens adds to already established physical health disparities. This requires critical attention from both practice and policy.

Neighborhood Social Cohesion, Physical Disorder, and Daily Activity Limitations Among Community-Dwelling Older Adults.

INTRODUCTION: Although extensive factors have been examined for limitations in activities of daily living (ADL) and instrumental activities of daily living (IADL), it remains unclear as to the impacts of neighborhood-level factors on ADL and IADL limitations. Thus, we aim to examine whether neighborhood characteristics are predictive of limitations in ADL and IADL. METHODS: A total of 7,407 participants were selected from the National Health and Aging Trend Study. We used data from round 1 (2011) to round 8 (2018). Neighborhood characteristics were measured as social cohesion and physical disorder. Daily activity limitations were counted based on the domains of ADL and IADL. Mixed-effects negative binomial regression analyses were performed to estimate the effects of neighborhood features on ADL and IADL limitations. RESULTS: Better neighborhood social cohesion significantly predicted less limitations in ADL (incidence rate ratio [IRR] = 0.98, 95% confidence interval [CI] = 0.96 - 0.99) and IADL (IRR=0.96, 95% CI = 0.95 - 0.98). More physical disorder predicted more IADL limitations (IRR=1.04, 95% CI = 1.01 - 1.06), but was not associated with ADL limitations. CONCLUSION: Neighborhood social cohesion is essential in enabling older adults to perform both basic self-care activities and more complex tasks, while neighborhood physical disorder is significant to older adults' capability in performing more complex sets of activities so as to age in place. The study findings underscore the importance of improving both social and physical aspects of neighborhood environment to facilitate older adults' daily activity performance.

Perceived neighborhood social disorder as a predictor of depressive symptoms among unmarried older women and the stress-buffering effect of friends support.

The current study examined whether perceived neighborhood social disorder predicted depressive symptoms among unmarried older women (N = 823) drawn from the 2016 Health and Retirement Study. This study also tested the stress-buffering effect of friends support. A negative binomial regression model showed that higher perceived neighborhood social disorder was associated with higher depressive symptoms. The number of close friends was a significant factor, but no stress-buffering effect of friends support was identified. This study highlights the adverse effect of negative perceptions of the neighborhood social environment on unmarried older women's depressive symptoms.
