We analyzed pooled data from the 2013-2017 National Health Interview Survey (n = 154,485) and found that the health advantage of marriage applied only to heterosexuals and, to a lesser extent, gays and lesbians. Similarly, no research has examined how the gender composition of a couple may shape bisexuals' health outcomes above and beyond the effects of sexual orientation.
No studies to date have examined the health effects of marriage among bisexuals, one of the most disadvantaged but understudied sexual minority groups, although a few have shown mixed results for gays and lesbians. However, this marital advantage paradigm has been developed primarily based on heterosexual populations. It has long been documented that married individuals have better health outcomes than unmarried individuals.
