Gender, marital status, and body weight in older U.S. adults

Marital terminations are life transitions that may lead to changes in diet, activity, and body weight. This investigation examined how marital status was associated with relative body weight, underweight, overweight, and obesity among men and women in the United States using cross-sectional nationally representative data from the 1992 HRS cohort age 51–61 and the 1993 AHEAD cohort age 70 and older. Results in the HRS cohort revealed that even when adjusting for demographic and behavioral variables, widowed women were significantly more likely to be obese than married women, while men who were never married, divorced, or separated were more likely to be underweight. Results in the AHEAD cohort showed few significant associations between marital status and weight for either men or women when demographics were controlled. Clear gender variations appeared to exist in how marriage is related to body weight among unmarried older adults, with widows in their 50s being obese and divorced/separated/never married men being underweight. However, marital status differences in weight were not present among much older adults of either gender.
