The study is the first to use national, population-based data to evaluate differences in health outcomes and behaviors among lesbian, gay and bisexual older adults. Using two-year survey data of 33,000 heterosexual and LGB adults ages 50 and older from a probability-based study of the U.S. Centers for Disease Control and Prevention, researchers from the UW School of Social Work report noticeable health disparities between LGB and heterosexual adults.
