Australia: Women who identify as “mainly heterosexual” report poorer health, greater health-risk behaviors, and higher rates of victimization than women identifying as “exclusively heterosexual"

Abstract: In recent decades, the ways in which sexual minorities identify have changed dramatically. In response, social and health surveys have begun offering a greater range of response options within sexual orientation questions—for example, intermediate categories for “mainly heterosexual” and “mainly lesbian/gay” alongside the more common response options of “heterosexual,” “bisexual,” and “lesbian/gay.” Recent studies indicate that women who identify as “mainly heterosexual” report poorer health, greater health-risk behaviors, and higher rates of victimization than women identifying as “exclusively heterosexual.” However, we know very little about the demographic profile of women who choose the “mainly heterosexual” identity label compared to the adjacent “exclusively heterosexual” or “bisexual” labels or about changes over time in the prevalence and correlates of “mainly heterosexual” identification. This study addressed these knowledge gaps by modeling unique, high-quality survey data from three national cohorts of Australian women (Australian Longitudinal Study on Women’s Health, 2000–2017, n = 76,930 observations). Consistent with the facilitative environments model, we document stark cross-cohort increases in the percentage of Australian women identifying as “mainly heterosexual”—from ∼1% of those born in 1946–1951 to ∼26% of those born in 1989–1995, coinciding with comparable declines in the percentage of women identifying as “exclusively heterosexual.” We also found evidence of cohort differences in the associations between key sociodemographic factors—such as age, education, and socioeconomic status—and the likelihood of women identifying as “mainly heterosexual.” Finally, our results indicate that same-sex sexual attractions were more strongly associated with “mainly heterosexual” identification than was same-sex sexual behavior.
