Purpose: This study examined whether employment status during mid-life and older adulthood is associated with physical function impairment., Methods: Participants were 2700 women in the multiracial/multiethnic Study of Women's Health Across the Nation. Time-varying, lagged, and cumulative exposure analyses modeled associations between self-reported employment status and the likelihood of severe physical function impairment across 19 years of follow-up., Results: Independent of demographic variables, women who were not working (OR = 1.58, 95% CI = 1.22, 2.04) or employed part-time (OR = 1.29, 95% CI = 1.04, 1.61) were more likely to report severe physical function impairments than women employed full-time. This same pattern was seen in lagged analyses predicting risk of physical function impairment from employment status at the prior assessment (not working vs. full-time: OR = 1.53, 95% CI = 1.08, 2.18; part-time vs. full-time: OR = 1.53, 95% CI = 1.17, 2.00). The likelihood of severe physical function impairment increased by 20% for every additional 10% of follow-up spent not working (OR = 1.02, 95% CI: 1.01, 1.03). Associations were robust to adjustment for health-related variables, body mass index, and physical activity., Conclusions: Women with lower levels of employment from mid-life to older adulthood were more likely to experience severe impairment in physical function. However, the underlying mechanisms, and the timescales over which associations unfold, require further study., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Purpose: Changes in employment status have shown inconsistent associations with adiposity. This study tested whether the presence of elevated depressive symptoms explains variability in the time-varying association between employment status and central adiposity., Method: Employment status, depressive symptoms, and waist circumference (WC) were assessed annually over 10 years in a multiethnic sample of 3220 midlife women enrolled in the Study of Women's Health Across the Nation. Linear mixed-effects models tested time-varying associations of employment status, depressive symptoms, and their interaction with WC., Results: WC increases were greatest during the years of combined nonemployment and elevated depressive symptoms (1.00 cm/y) and lowest in the years of full-time employment and elevated depressive symptoms (0.25 cm/y), compared with the years of full-time employment and nonelevated depressive symptoms (0.51 cm/y). Employment status was unrelated to WC in years without elevated depressive symptoms. The pattern of results was unchanged when analyses were restricted to preretirement observations and did not vary according to WC at baseline or ethnicity/race., Conclusions: Identifying and managing depressive symptoms in midlife women who are not working may help prevent increases in central adiposity., (Copyright © 2014 Elsevier Inc.
