Association between the Expression of Sexual Orientation and/or Gender Identity and Mental Health Perceptions in the Peruvian LGBTI Population.

Introduction: The non-expression of sexual orientation and gender identity can affect mental health in the lesbian, gay, bisexual, transgender, and intersex population in Peru.

Method: Secondary, observational, analytical, and cross-sectional analyses of data from the "First Virtual Survey on the LGBTI population" were conducted with a population ( = 11,345) of LGBTI adults aged 18 years old or more. The variables of mental health and expression of sexual orientation and/or gender identity were measured using a self-reported questionnaire that did not include a validated scale; questions with multiple alternatives that included "yes" and "no" options were used.
