Sex Differences in the Relationship between Military Service Status and Functional Limitations and Disabilities

This paper examines the relationship between military service status (active duty, veteran, never served), sex, and six functional limitations/disabilities using data from the 5% sample of the 2000 U.S. Census. We estimate multivariate logistic regression models separately for men and women, and evaluate sex differences by comparing coefficients across models using a Wald chi-square test and computing predicted probabilities. For both men and women, the highest rates of functional limitation/disability are observed among veterans, while the lowest rates are recorded among active duty personnel. The increased odds of functional limitations/disabilities associated with veteran status is higher among women than men, whereas the decreased odds of functional limitations/disabilities associated with active duty status is lower among women than men. The predicted probabilities, which are based on a subgroup of 40-49 year olds with select sociodemographic characteristics, indicate that veteran women's probabilities of many types of functional limitations/disabilities equal or exceed those of veteran men. Overall, the findings suggest women experience a more detrimental effect of past military service and a less beneficial effect of current military service. More life course analysis with longitudinal data that accounts for factors that influence sex-differentiation with respect to selection into military service, experiences in the military, and the short- and long-term consequences of military service is needed to fully understand sex differences in the relationship between military service and functional limitations/disabilities.
