Transitions in social isolation profiles over time and factors associated with them among older adults Authors: Sung, Pildoo; Chan, Angelique Wei Ming; Visaria, Abhijit; Lee, June May-Ling Abstract: The interplay between the structural, functional, and evaluative dimensions of social isolation and their temporal dynamics remains underexplored. We investigated (1) older adults’ distinct social isolation profiles, each characterized by varying degrees of social ties, perceived social support, and loneliness; (2) the stability and changes in these profiles over time; and (3) factors associated with key transition patterns. Using random-intercept latent transition analysis on two-wave longitudinal data from 1305 older Singaporeans aged 60–91 years, we identified five time-invariant profiles: (1) diverse ties and support, less lonely (24.4 % at baseline); (2) relative ties and support, less lonely (25.8 %); (3) friend ties and support, less lonely (9.3 %); (4) less supportive ties, less lonely (31.1 %); and (5) less supportive ties, lonely (9.4 %). Over time, more than half of the respondents (56.1 %) changed profiles. Specifically, less educated and financially insecure older adults were more likely to transition from profiles with supportive ties (profiles 1–3) to the profile with less supportive ties (profile 4), without a concomitant rise in loneliness. Instead, increases in depressive symptoms were associated with persistence in or transition into the lonely profile (profile 5). Overall, socioeconomic disadvantages and deteriorating mental health were identified as distinct risk factors for reduced perceived support and loneliness, respectively, highlighting the necessity for tailored interventions. 2026-05-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/210720 Title: Tracking the decline of first marriage in South Korea: Timing, quantum decline, and pandemic disruptions Authors: Yoo, Sam Hyun Abstract: BACKGROUND In South Korea, where most births occur within marriage, the country's record-low fertility has put renewed attention on the long-term decline in first marriage. Despite rising policy and academic interest, systematic demographic analyses that disentangle structural and timing components of nuptiality change remain limited, especially in East Asia. OBJECTIVE This study examines trends in the quantum and timing of first marriage in South Korea from 1993 to 2023 and assesses whether the decline reflects structural retreat, postponement, or both. METHODS Using legally registered marriage data from the national vital statistics system, we construct three period indicators: the total first marriage rate (TFMR), the period proportion ever married (PPEM), and a tempo-adjusted PPEM (PPEM*). We estimate the never-married population using age-specific proportions from the census, applied to mid-year resident registration data. All indicators are calculated separately for men and women. RESULTS Both TFMR and PPEM declined markedly over three decades. Among women, PPEM and PPEM* showed parallel trajectories, indicating a structural retreat from marriage. Among men, PPEM fluctuated more sharply, and its widening gap with PPEM* after 2015 reveals stronger tempo effects. The temporary convergence in 2020 reflects compositional change due to a sharp fall in international marriages during the pandemic. CONCLUSIONS The findings reveal a sustained decline in first marriage for both sexes, with men showing lower levels and greater sensitivity to timing shifts and external disruptions. 2026-01-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/210301 Title: Stress, Social Isolation Profiles, and Depressive Symptoms Among Older Adults in a Low-Income Community in Singapore Authors: Sung, Pildoo; Koh, Vanessa Jean Wen; Chan, Angelique Abstract: Objectives: To identify distinct social isolation profiles and their associations, both direct and stress-moderating, with depressive symptoms using objective and subjective indicators of social isolation among older adults in a low-income community. Methods: Latent class analysis and multivariable regression were conducted with data from 881 individuals aged 60 years or above residing in public rental housing in the Chin Swee area of Singapore. Results: Four profiles emerged: “well-connected and less lonely” (27.9%), “structurally isolated but less lonely” (56.4%), “somewhat isolated and moderately lonely” (11.3%), and “severely isolated and highly lonely” (4.4%). The latter two profiles demonstrated significantly greater depressive symptoms than the former two. Additionally, the “somewhat isolated and moderately lonely” profile showed heightened vulnerability to stressors, exhibiting stronger associations between life stressors and depressive symptoms compared with the “well-connected and less lonely” profile. Conclusions: Subjective loneliness, more so than objective structural isolation, is pivotal in shaping older adults' mental health and stress vulnerability within low-income settings. Interventions should consider decoupling loneliness from social isolation, tailoring support to the specific needs associated with different social isolation profiles. 2025-12-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/209030 Title: 학교 없는 교육 : 학교 밖 교육의 가능성과 그 방식을 말하다 Authors: 박순석 2025-06-01T00:00:00Z
