HIS AND HER EVERYDAY LIFE: GENDER DIFFERENCES IN OLDER ADULTS’ SOCIAL AND PHYSICAL ACTIVITY

Abstract The literature links social integration to better physical health, but little research asks how contact with diverse social partners influences older adults’ physical activity in a daily context. We examined this link using the Daily Experiences and Well-being Study and explored whether this link varied by gender. The sample included 175 older women and 138 older men who reported their contact with close partners (e.g., family/friend) and not-close partners (e.g., acquaintances) throughout each day across 5 days. Participants also wore Actical accelerometers to track physical activity. Multilevel models revealed significant gender differences. Older men had reduced physical activity when having contact with close partners, whereas older women maintained physical activity during such contact. Both older men and women had increased physical activity when having contact with not-close partners, but this link was stronger for men. This study advances our understanding of gender differences in older adults’ social experiences and well-being.

DISCORDANT CHRONIC CONDITIONS AND DEPRESSIVE SYMPTOMS AMONG MIDDLE-AGED AND OLDER COUPLES
Courtney A. Polenick, 1 Kira S. Birditt, 1 Angela Turkelson, 1 Benjamin Bugajski, 1 and Helen C. Kales 1 , 1. University of Michigan, Ann Arbor, Michigan, United States Discordant chronic conditions (i.e., those with competing management requirements) have adverse consequences for well-being, yet little is known about their implications among couples. We evaluated how depressive symptoms are linked to discordant conditions within individuals and between spouses across an 8-year period. The U.S. sample included 1,116 middleaged and older couples from five waves (2006 -2014) of the Health and Retirement Study. Longitudinal actor-partner interdependence models controlled for age, minority status, education, depressive symptoms in the previous wave, and each partner's report of baseline marital quality and number of chronic conditions in each wave. Wives and husbands with their own discordant conditions reported higher depressive symptoms, and this association intensified over time. Over and above this link, husbands had higher depressive symptoms when there were discordant conditions between spouses. Both individual-level and couplelevel discordant chronic conditions appear to have enduring implications for depressive symptoms in middle and later life.

HOW DO MENTAL HEALTH TRANSITIONS SHAPE THE ROLE OF ADULT CHILDREN IN OLDER ADULTS' SOCIAL NETWORKS?
Laura Upenieks 1 , 1. University of Toronto, Toronto, Canada, Canada This study considers the role of adult children in the core networks of older adults undergoing mental health change. Taking a multidimensional perspective of the network system, I consider (a) presence of child(ren), (b) contact with children network members, and (c) embeddedness of children within the network using longitudinal data from the United States. Parameters were estimated with generalized estimating equations from the pooled panel data. There was no evidence that mental health transitions lead to systematic forms of child reshuffling or increased contact with child ties. Children that remained in networks, however, showed increased contact with other members of the network when the parent underwent depression onset, but became less embedded when their parents had chronically high levels of depression. These patterns may have far-reaching consequences for older people and their children, which could include increased feelings of loneliness and social isolation for parent and child alike.
