Veterans and functional status transitions in older Americans.

OBJECTIVES: This research examines the relationship of veteran status with functional status transitions in older Americans. METHODS: Data for this study come from the Survey of Asset and Health Dynamics among the Oldest Old. We use a structural multinomial logit model to decompose the effect of older veterans into the direct effect and the indirect effects via physical health conditions and mental disorders on functional status transitions. RESULTS: Although there is no distinct association among those functionally independent at baseline, veteran status significantly impacts age-dependent transitions from functional dependence to other statuses. At age 85, the excess mortality and the lower level of functional resolution among functionally dependent veterans are considerable. CONCLUSIONS: Physical health is more important than mental health in transmitting the effect of veteran status on functional status transitions in functionally dependent persons.

Predictors of exercise compliance in individuals with Gulf War veterans illnesses: Department of Veterans Affairs Cooperative Study 470.

Although the health benefits of exercise for individuals with Persian Gulf War veterans illnesses (GWVI) are documented, many of these individuals do not exercise regularly enough to obtain benefits. The purpose of this study was to investigate factors predicting exercise compliance among individuals with GWVI in a multicenter, randomized, clinical trial. Participants were 1,092 veterans who reported at least two of the following cardinal symptoms of GWVI: (1) fatigue, (2) musculoskeletal pain, and (3) cognitive problems. Participants received exercise alone or exercise and cognitive-behavioral therapy. The overall level of compliance was relatively low during the exercise treatment phase (46.2%) and decreased by one-half during the follow-up period (23.0%). Predictors of compliance during treatment included less pain and greater age, motivation, and body mass index. Predictors of compliance during the follow-up period included less pain and greater age. The results highlight factors that affect adoption and maintenance of physical activity in a population with GWVI.
