A team of public health researchers looked at health-care patterns among gay and bisexual men before and after Massachusetts legalized same-sex unions in 2003 (this was prior to the state’s health insurance expansion). Health-care research has increasingly looked at how policy interventions that change the larger environment impact health-care outcomes. In this case, they wanted to know whether legal same-sex marriage — which had the potential to reduce risk factors such as stress — might have an impact.
