Objective This study aims to identify distinct patterns of 10-year multimorbidity trajectory among Korean older adults and examine factors associated with the patterns. Methods Data were drawn from the six waves of the Korean Longitudinal Study of Ageing (KLoSA, 2006–2016). We examined trajectories of multimorbidity of 1,705 older adults aged 65 and older using Growth Mixture Modeling. Then, the identified patterns were used as dependent variables to examine the correlates of multimorbidity trajectories. Explanatory variables considered were sociodemographic, psychological, health behavioural and interpersonal factors at baseline. Results Four distinct patterns of multimorbidity trajectories were identified: ‘maintaining-low’ (59.4%), ‘chronically-high’ (7.5%), ‘moderately-increasing’ (26.0%) and ‘rapidly- increasing’ (7.1%). Gender, depressive symptoms, life satisfaction and frequency of contacts with others were associated with trajectory membership. Specifically, women were more likely to be in the ‘chronically-high’ group than any other groups. Compared to the ‘maintaining-low’ group, those with higher levels of depressive symptoms and lower levels of life satisfaction were more likely to belong to the ‘chronically-high’ group and ‘moderately-increasing’ group, respectively. Respondents who had less frequent meetings with others in close relationships were more likely to be in the ‘rapidly-increasing’ group than the ‘maintaining-low’ group. Discussion These findings are suggestive of distinct trajectories of multimorbidity across older adulthood, indicating that multimorbidity experiences might differ among older adults. Moreover, results suggest that there may be gender inequalities in multimorbidity trajectories, and that levels of psychological well-being and social engagement could be useful in identifying older adults who are at higher risk of worsening multimorbidity.

The aims of the present study were to examine whether daily stressors are associated with engagement in emotional support and whether these associations differ by gender. Analyses were conducted using Wave 2 of Midlife in the United States data and its subproject National Study of Daily Experiences. The sample consisted of adults aged 33 to 84 (N = 1,622). Using multinomial multilevel analysis, we looked at the associations between lagged and concurrent daily stressors with engagement in emotional support. For concurrent associations, people who experienced stressors were more likely to both give and receive, solely give, and solely receive emotional support compared with those who did not have any stressors. Women were more likely to engage in both giving and receiving of emotional support compared with men when they experienced stressors during the same day. In terms of the lagged associations, both men and women who experienced stressors during the previous day were more likely to both give and receive emotional support the next day compared with those who did not experience any stressors during the previous day. These results suggest that experiencing daily stressors facilitates giving and receiving of emotional support at daily level in adulthood.

Research documents the pernicious effects of daily stressors on well-being, but often ignored in these studies are people reporting no stressors. The current study compared adults who reported no daily stressors with adults who reported at least one stressor across 8 consecutive days on measures of well-being. Of the 2,804 respondents (age range = 25–75 years, M = 53.46) from the Midlife in the United States Survey daily diary study, 10% reported experiencing no stressors across 8 days. Those reporting no stressors were generally older, male, unmarried, and were less likely to work, provide or receive emotional support, or experience positive daily events. They reported greater daily affective well-being and fewer chronic health conditions but had lower levels of cognitive functioning. Findings suggest that daily stressors may serve as a proxy to engagement in social activities, where a lower level of engagement is related to better physical and emotional well-being but lower levels of cognitive functioning.

One of the important determinants of well-being among aging parents is their relationship with adult children. Using the two waves of the Korean Longitudinal Study of Ageing, this study examined how different types of ties with adult children affect the life satisfaction of the Korean middle-aged, the young-old, and the oldest-old adults. Multigroup analysis was used to see if the effects of ties with adult children differ by the three age-groups. The results showed that frequency of contact had positive effect on life satisfaction for all of the age-groups. However, coresidence with children had a negative effect for the middle-aged, but a positive effect for the oldest-old. Finally, exchanges of support with adult children had significant effects only for the young-old. These results show that the importance of different types of ties with children change according to aging parents' life stages.

Contact and relationship quality between adult children and aging parents are two widely used indicators of intergenerational solidarity and are often assumed to be positively correlated. However, the association between the two may depend on characteristics of the parent involved. Using Family Exchanges Study Wave 1, this study assessed whether parental difficulties—measured as functional limitations and life problems—and gender moderated the associations between middle-aged adults’ contact and relationship quality with their parents. We found that more frequent email or phone contact was associated with worse relationship quality for fathers who had functional limitations. For life problems, however, more contact was not related to relationship quality for fathers with life problems. The associations did not differ by mother’s difficulties. These results suggest that frequent contact between middle-aged adult children and aging parents does not uniformly reflect better relationship quality but rather depends on parents’ characteristics.
