Gender minority stress in transgender people: a major role for social network

Changes in affect variability after starting gender-affirming hormone therapy

Negative affect variability is determined by how often and how strongly negative affect changes over time. Cisgender women report greater variability in affect than cisgender men. It has been suggested that sex hormone changes may influence affect variability. Transgender people frequently opt to use sex hormones in the form of gender-affirming hormone therapy (GAHT), but the extent to which GAHT can change negative affect variability is not yet clear. Therefore, this study aims to study changes in negative affect variability after starting GAHT. We have included data from 92 participants from the RESTED study: 47 persons starting masculinizing hormones (MH), i.e. testosterone, and 45 persons starting feminizing hormones (FH), i.e., estrogens and anti-androgens. Participants completed up to 7 consecutive daily diaries at each of three time points: before starting GAHT, and after 3 and 12 months of GAHT. The daily diaries collected participants' reports on symptoms related to negative affect: experienced low mood, less interest, tense feelings and restless feelings. We have used linear mixed models to compare negative affect variability during one week, corrected for mean negative affect, between groups (MH versus FH) and measurement time points. Results show that in the MH group, variability in tense feelings and restless feelings decreased after 3 and 12 months of GAHT, respectively. In the FH group, variability in low mood increased after 3 months and 12 months of GAHT, as did variability in restless feelings after 12 months of GAHT. Group comparisons indicate significant group differences in changes in variability in low mood and restless feelings, with stronger increases in variability of negative affect in the FH group compared to MH group after 3 and 12 months of GAHT. Our findings indicate that variability patterns in negative affect in transgender persons change after starting GAHT, with participants who start masculinizing hormones moving to a profile which more closely resembles that of cisgender men and participants who start feminizing hormones moving to a profile which more closely resembles that of cisgender women. Future studies should focus on measuring both negative and positive affect variability during GAHT, preferably through multiple measurements per day, taking into account diverse social and daily contextual factors during GAHT.

White Matter Microstructure Among Straight and Gay Cisgender Men, Sao Praphet Song, and Straight Cisgender Women in Thailand

White matter (WM) microstructure is differentiated in relation to sex/gender, psychosexuality, and, among transgender people, gender-affirming hormone (GAH) use. Prior research focused on Western samples, which limits generalizability to other populations. Here, diffusion tensor imaging (DTI) was used to assess WM microstructure in a Thai sample (N = 128) of straight cisgender men, straight cisgender women, gay cisgender men, and sao praphet song (i.e., transfeminine individuals assigned male at birth and sexually attracted to cisgender men). Sao praphet song were further grouped by GAH use. Groups were compared on fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) using whole-brain tract-based spatial statistics (TBSS). FA, AD, and RD were further examined via multivariate analysis to assess covariance across WM microstructural indices and participant groups. A significant multivariate pattern differentiated the feminine- from masculine-identifying groups irrespective of sex assigned at birth and suggested WM tissue organization was greater among the latter in the bilateral cingulum, anterior corona radiata, left corpus callosum, and right superior longitudinal fasciculus, forceps minor, and corticospinal tracts. TBSS analyses reinforced that WM differed by gender identity in various regions. Among sao praphet song, GAH use was associated with lower regional FA, suggesting less WM organization bilaterally in the corpus callosum, cingulum, and anterior corona radiata. The findings aligned with prior studies in Western samples, indicating cross-population generalizability of WM microstructural differentiation in relation to sex/gender, psychosexuality, and GAH use.

Changes in depression symptom profile with gender-affirming hormone use in transgender persons

BACKGROUND

Women show higher prevalence of depression and different symptomatology than men, possibly influenced by sex hormones. Many transgender persons, who face a high risk of depression, use Gender-Affirming Hormone Therapy (GAHT), but the impact of GAHT on depressive symptom profiles is unknown.

METHODS

This study examined depressive symptoms in transgender persons before GAHT and after 3- and 12 months of GAHT. We used the Inventory of Depressive Symptomatology-Self Report to assess depressive symptoms, exploratory factor analysis (EFA) to assess symptom clusters, and linear mixed models to assess changes in symptom clusters.

RESULTS

This study included 110 transmasculine (TM) and 89 transfeminine (TF) participants. EFA revealed four symptom clusters: mood, anxiety, lethargy, and somatic symptoms. Changes in total depressive symptoms significantly differed between TM and TF groups. After 3 months of GAHT, TM participants reported improvement in lethargy (-16 %; 95%CI: -29 %; -2 %), and after 12 months TF participants reported worsening in low mood (24 %; 95%CI: 3 %; 51 %), but absolute score changes were modest. Neither group showed changes in anxiety or somatic symptoms.

LIMITATIONS

This study had limited sample sizes at 12 months follow-up and did not include relevant biological or psychosocial covariates.

DISCUSSION

Changes in depressive symptoms after GAHT use differ in TM and TF persons: TM persons report slight improvements in lethargy, whereas TF persons report a slight increase in low mood. Starting GAHT represents a significant life event with profound social and physical effects, and further research should assess social and biological effects of GAHT on mood-related symptoms.

Minority stress and mental health in European transgender and gender diverse people: A systematic review of quantitative studies

The current study aimed at systematically reviewing evidence on the relationships between gender minority stress and mental health outcomes among European transgender and gender diverse (TGD) individuals. A systematic search was conducted in PsycINFO, PubMED, Scopus, and Google Scholar. It was based on Boolean operators to combine terms related to minority stress, TGD identities, and mental health. Thirty studies were identified as eligible. The results confirmed that gender minority stress factors are significantly related with mental health problems among European TGD individuals. Distal stressors were identified as strongly associated with poorer mental health, with gender-related discrimination emerging as the most documented risk factor. The significant role of proximal stressors was also highlighted, with some mediation analyses detecting an indirect effect on mental health. However, identity concealment appeared unrelated to mental health outcomes. Resilience-promoting factors buffering the impact of stressors were also identified, including self-esteem, pride, transitioning, and social support. Conversely, data on community connectedness as a source of resilience were inconclusive. The studies reviewed have several limitations, including lack of longitudinal designs, sampling bias, variability in measurement methods, and unaccounted ethnic variables. Research and clinical recommendations in this field are reported.
