Haas, PhD, Center for Demography of Health and Aging, University of Wisconsin-Madison, University of Wisconsin, 1180 Observatory Drive, Madison, WI 53706, (319) 248-1266, shaas@ssc.wisc.edu, and Eric Reither, MA, MS, Population Health Sciences, University of Wisconsin, 756 WARF Office Building, 610 Walnut St, Madison, WI 53726.

Objectives: To determine the association between body mass index (BMI) and quality of life (QOL) in older Americans. To determine how weight gain or loss affects QOL. Design/Subjects: Population-based cohort study. 9,181 persons in the Health and Retirement Study (HRS) 1992-2000, a nationally-representative, population-based sample of non-institutionalized Americans ages 51-61 in 1992. Exclusions were: not age-eligible, not self-report, BMI<19, and died before 1994. Measures: BMI is assessed using self-reported height and weight. QOL is assessed using self-reported global health, global emotional health, and depression. Results: In cross-section, obesity is associated with increased depression (OR=1.19, 95% CI: 1.02, 1.38) and worse global health (OR=1.54, 95% CI: 1.33, 1.77). Morbid obesity is associated with increased depression (OR=1.66, 95% CI: 1.36, 2.02), worse emotional health (OR=1.55, 95% CI: 1.28, 1.89), and worse global health (OR=2.75, 95% CI: 2.29, 3.29). Participants who lowered their BMI category by 1994 had less depression (OR=0.65, 95% CI: 0.54, 0.80), better emotional health (OR=0.64, 95% CI: 0.53, 0.78) and better global health (OR=0.66, 95% CI: 0.54, 0.80) in 1994. Participants who increased body mass categories had worse global health (OR=1.50, 95% CI: 1.26, 1.79) in 1994, but no statistically significant change in depression (OR=0.98, 95% CI: 0.81, 1.18) or emotional health (OR=0.97, 95% CI: 0.80, 1.16). Conclusions: Higher BMI is associated with reduced QOL in older Americans. In this population, losing weight improves QOL in general while gaining weight reduces global health.

Learning Objectives: At the conclusion of the session, the participant will be able to
