Changing demographic characteristics of women veterans: results from a national sample.

Women veterans are a small but growing percentage of the U.S. veteran population. There are some indications that, along with this increase, the characteristics and military experiences of younger women veterans differ considerably from those of older colleagues. Many of these characteristics are not well defined, but they could have implications for women's health care needs and health policy initiatives. Using the first sample drawn from the Department of Veterans Affairs' new National Registry of Women Veterans, we designed and administered a telephone survey to a representative sample of women veterans across several major age groups. Groups approximated primary eras of military and wartime service based on the assumption that different eras might be associated with differing military experiences. We found a number of age-related similarities and differences in women veterans' demographic characteristics, military experiences, physical health symptoms, and functional outcomes. Women veterans in general also differed from female civilian counterparts on exposure to sexual trauma. Trends in the population of women veterans are likely to have implications for the variety of health care systems that treat women veterans.
