A study published in the "International Journal of Eating Disorders" used data from the Massachusetts Youth Risk Behavior Surveys from 1999 to 2013 to examine how disordered eating has trended in heterosexual versus LGB (lesbian, gay, bisexual) youth. The data from over 26,000 surveys investigated the practices of purging, fasting, and using diet pills. It was found that, "sexual minority youth report disproportionately higher prevalence of disordered eating compared to heterosexual peers: up to 1 in 4 sexual minority youth report…patterns of disordered eating…" In addition, the gap between the number of LGBT females and heterosexual females controlling weight in unhealthy ways has continued to widen.
