Temporal Trends in Mental Health in the United States by Gender Identity, 2014-2021.

To examine the temporal trends in the transgender-cisgender mental health disparity in the United States. We used 2014-2021 US Behavioral Risk Factor Surveillance System Survey data with logistic and ordinary least squares regression to document temporal trends in the transgender-cisgender disparity in self-reports of the number of poor mental health days in the past month and frequent mental distress. In 2014, cisgender individuals reported a mean average of 3.68 (95% confidence interval [CI] = 3.65, 3.70) poor mental health days compared with a mean average of 5.42 (95% CI = 4.68, 6.16) poor mental health days among transgender respondents. The size of this disparity adjusted by differences in observable characteristics increased by 2.75 days (95% CI = 0.58, 4.91) over the sample period. In 2014, 11.4% (95% CI = 11.3%, 11.5%) of cisgender adults reported frequent mental distress compared with 18.9% (95% CI = 15.9%, 22%) of transgender adults. By 2021, 14.6% (95% CI = 15.9%, 22%) of cisgender adults and 32.9% (95% CI = 30.7%, 35.1%) of transgender adults reported frequent mental distress. Policies are needed to address the worsening mental health of transgender and gender-nonconforming people in the United States. (. 2024;114(5):523-526. https://doi.org/10.2105/AJPH.2024.307603).
