This study investigates the changes in social network types among older adults in South Korea, and it examines whether, and to what extent, these changes influence their health and psychological wellbeing. Data were obtained from the Korean Longitudinal Study of Ageing. The sample was restricted to respondents over 65 years of age who participated in both the 2006 and 2008 surveys (N = 3,501). The social network types for both years were derived by Latent Class Analysis. Changes in network types over time were then identified. A series of multivariate regression analyses were conducted to examine the effects of social network changes on self-rated health, depressive symptoms and life satisfaction. Restricted, Family, Friend and Diverse network types were derived in each wave of the study. Although the direction of social network changes was not always towards the Restricted type, the Restricted network was the most prevalent and stable type among older Koreans. Older adults who remained in or transitioned to restricted types of social networks were more likely to have poor self-rated health, higher levels of depressive symptoms and lower levels of life satisfaction. This study adds to the limited body of literature on longitudinal network typology, and it expands the knowledge of social network types among older adults in diverse social and cultural contexts.

This study investigated to what extent income status and race/ethnicity in old age interplayed with disaster preparedness. Data came from the 2010 Health and Retirement Study, a nationally representative panel survey of older Americans over 51 years old. Our sample was restricted to respondents who participated in a special survey about disaster preparedness (N=1,711). Disaster preparedness was measured as a score, which includes 13 variables. Race/ethnicity was categorized by White, Black, and Hispanic. Low income was defined as below 300% of the federal poverty line. OLS regression was used to examine the main and interaction effects of race/ethnicity and lower income status on disaster preparedness scores. We found that older adults in lower income status had lower preparedness level than those in higher income (Coef. =-0.318, p<.01). Hispanics tend to be less prepared compared to White and Blacks (Coef. =-0.608, p<.001). Preparedness of Black elders was not significantly different from that of Whites. However, interestingly, Black elders in lower income status were significantly less prepared for disaster than other groups (Coef. =- 0.622, p<.05). This study identified vulnerable subgroups of older adults for disaster preparedness and suggests that preparedness programs should target minority and low income elders.

There was evidence of distinct profiles of depressive symptoms in late middle age and of interrelated life course mechanisms underlying the influences of childhood SES on later life depression.
