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). Implications for public health: Sexual identity remains an important marker of risk for health and wellbeing outcomes within Australia, underscoring the importance of fully integrating sexual identity in health policy and practice.
