ABSTRACT
BACKGROUND: Sexual minorities have continuously been found to experience poorer mental health compared to the general population, despite promising changes in attitudes and legislation throughout the 21st century in many Western countries. The present study is one of the first to assess group-level changes over time in mental health among sexual minorities compared to their heterosexual counterparts.
METHODS: We used four waves of a Finnish population-based survey spanning 16 years (2006-2022) to compare heterosexual and sexual minority adults on depression and anxiety symptoms, alcohol use, and sexual distress.
RESULTS: Sexual minority individuals reported more depression and anxiety symptoms, sexual distress, and alcohol use relative to their heterosexual counterparts at all time points. There were no group differences in the direction or rate of change in group means from 2006 to 2022. Depression and anxiety symptoms showed equally large increases, and alcohol use showed equally large decreases among both heterosexual and sexual minority participants.
CONCLUSIONS: Contrary to our expectations based on minority stress theory, differences in mental health between sexual minority and heterosexual individuals persist despite changes in the sociolegal status of sexual minorities during the first two decades of the 21st century. Our findings align with the increasing general trend in anxiety and depression symptoms, which seems to affect the whole population regardless of sexual orientation. We conclude that the effect of legislative societal improvements seems to be small, and the mental health gap between sexual minority and heterosexual adults is likely maintained by factors not included in our study.
