Sleep in Trans and Non-Binary Individuals: A Question of Gender?
AI Summary
Alarmingly high rates of poor sleep and subclinical insomnia among trans and non-binary people, two to four times higher than cisgender benchmarks.
Psychosocial factors explained substantially more variance in sleep outcomes than structural variables or gender identity; transition options largely did not affect sleep.
Feminising hormones linked to lower insomnia; non-binary individuals had worse scores and higher medication use; trans women reported more nocturia; over 30% had maintenance problems.
Sleep problems are increasingly prevalent in society. One group that is disproportionately affected includes transgender and non-binary individuals, whose sex assigned at birth does not match their identified gender. This mismatch can lead to gender minority stress and increases the risk of mental disorders. However, research on sleep in this population remains extremely limited, especially when considering potential effects of gender-affirming care, including gender-affirming hormone therapy. Therefore, we conducted an anonymous, Germany-wide online study with 469 trans and non-binary individuals to investigate sleep quality and insomnia severity using standardised questionnaires, accounting for structural and psychosocial factors. Poor sleep quality and subclinical insomnia were highly prevalent, at levels two to four times higher than published cisgender population benchmarks. Sleep quality and insomnia severity scores were worse in non-binary individuals than in trans women. Transition options did not significantly impact sleep quality and insomnia severity scores, whereas psychosocial factors explained substantially more variance than structural variables or gender identity alone. Additionally, people using feminising hormone treatment had lower insomnia severity scores than those not using hormone treatment. Trans women woke up significantly more often due to nocturia, whereas trans men and non-binary individuals had more sleep initiation problems. Non-binary individuals used sleep medication significantly more often than binary trans individuals. Over 30% of the participants experienced frequent sleep maintenance problems. This cross-sectional study found alarming rates of poor sleep and insomnia among trans and non-binary individuals. Future studies should further investigate and address potential moderating factors underlying poor sleep in this population.
