Mental health is a key part of overall well-being, shaping how we think, feel, and interact with others. It’s not just about avoiding mental illness—it plays a vital role in our quality of life. Practicing self-care can help nurture your mental health, and for those living with a mental illness, it can also support treatment and recovery.
A new long-term study from researchers at Åbo Akademi University in Finland shows that sexual minority individuals continue to experience significantly higher levels of mental health symptoms compared to heterosexual individuals—despite major social and legal advances over the past two decades.
Researchers analyzed four waves of population-based panel data collected across Finland in 2006, 2012, 2019, and 2022. Across the 16-year span, symptoms of depression and anxiety rose for both heterosexual and sexual minority participants, reflecting a general decline in mental well-being in the Finnish population. However, the mental health gap between the two groups persisted.
A central explanation examined in the study is minority stress theory, which proposes that sexual minority individuals experience unique, chronic stressors that negatively shape their mental health.
“Minority stress includes discrimination, negative attitudes, and the constant worry of being treated differently because one is not heterosexual,” explained Marianne Källström, the study’s lead researcher and a PhD student and university lecturer in psychology at Åbo Akademi University. She adds that earlier childhood experiences and genetic factors may also contribute to elevated mental health risks within sexual minority groups.
Notably, the study found that the disparity in mental health symptoms has not narrowed in the last 16 years—even as Finland has enacted laws aimed at improving equality, including the 2014 legalization of same-sex marriage.
“It was remarkable that the gap has not shrunk despite societal changes that should improve sexual minorities’ lives,” said Ida Pedersen, whose Master’s thesis contributed to the project.
The findings also reveal a steady decline in alcohol consumption across all participants over the study period, an encouraging trend given alcohol’s association with poor mental health. However, sexual minority individuals consistently reported higher alcohol use than heterosexual respondents at every measurement point.
Similarly, sexuality-related distress remained more common among sexual minority individuals but did not significantly change over the years for either group.
Overall, the results suggest that sexual minority individuals remain more vulnerable to mental health issues than the rest of the population. The researchers stress the importance of ongoing efforts to promote equality, reduce minority stress, and better understand the complex causes of mental health disparities in sexual minorities.
The study underscores a critical need: even as societies become more inclusive on paper, lived experiences and psychological well-being for sexual minority individuals may not improve at the same pace—highlighting the importance of targeted mental health support and further research.
