Family Discordance in Gender Identification Is Not Associated with Increased Depression and Anxiety Among Trans Youth.

Abstract

Purpose: We examined the relationship between parent- and child-reported gender identity of the youth with internalizing symptoms in transgender and gender-diverse (TGD) youth. In addition, we investigated differences in sex assigned at birth ratios and pubertal development stages in TGD and cisgender youth. Methods: We analyzed longitudinal data from the Adolescent Brain Cognitive Development study (ABCD), corresponding to baseline and 1st-to-3rd-year follow-up interviews (n = 6030 to n = 9743, age range [9-13]). Sociodemographic variables, self- and parent-reported gender identity, and clinical measures were collected. Results: TGD youth showed higher levels of internalizing symptoms compared with cisgender youth. However, this was not worsened by discordance in gender identification between TGD youth and parents. Over the 3-year follow-up period, the proportion of TGD participants increased from 0.8% (95% confidence interval (CI) [0.6-1.0]) at baseline to 1.4% (95% CI [1.1-1.7]) at the 3rd-year follow-up (χ² = 10.476, df = 1, false discovery rate (FDR)-adjusted p = 0.00256), particularly among those assigned female at birth (AFAB) in relation to people assigned male at birth (AMAB) (AMAB:AFAB at baseline: 1:1.9 vs. AMAB:AFAB at 3rd-year follow-up: 1:4.7, χ² = 40.357, df = 1, FDR-adjusted p < 0.0001). Conclusions: TGD youth in ABCD reported higher internalizing symptoms than cisgender youth, although this was not affected by parental discordance in gender identification. A substantial increase over time in TGD children AFAB was documented. More research is needed to understand the clinical implications of these preliminary results, for which the longitudinal design of ABCD will be crucial.
