The health and wellbeing of Australian lesbian, gay and bisexual people: a systematic assessment using a longitudinal national sample

Objective: This study revisits disparities in health and wellbeing by sexual identity in Australia, identifying which domains demand priority policy intervention, documenting differences between gay/lesbian vs. bisexual populations, and examining change over time in the relative health and wellbeing of sexual minorities. Method: I fitted multivariable ordinary least squares and random-effect panel regression models on 20 outcomes to compare the health and wellbeing of heterosexual, gay/lesbian and bisexual people, using 2012/2016 data from a national probability sample - the Household, Income and Labour Dynamics in Australia (HILDA) Survey. Results: I found strong associations between sexual minority identities and most health and wellbeing outcomes. These were comparatively larger for: role-emotional health, mental health and general health; bisexual compared to gay/lesbian people; and minority women compared to minority men. I found no change over time in the relative health and wellbeing outcomes of gay/lesbian people, but evidence of worsening circumstances among bisexual people. Conclusion: There are important disparities in the health and wellbeing profiles of different sexual minority populations in Australia, based on sex (male vs. female), sexual identity (gay/lesbian vs. bisexual), and observation time (2012 vs. 2016).
