Intake and risk of eating disorders do not seem to follow the sex assigned at birth, but rather gender identity, and transgender people assigned female or male at birth need different nutritional care.
Key Findings
Results
The prevalence of overweight was 50.0% among the transgender participants studied.
Sample consisted of 16 transgender people in the gender transition process.
Participants ranged in age from 18 to 53 years.
62.5% were assigned female at birth (AFAB) and 37.5% were assigned male at birth (AMAB).
Data were collected from March to May 2023.
Results
12.5% of transgender participants presented a high risk of eating disorders as measured by the Eating Attitudes Test-26 (EAT-26).
Risk of eating disorders was assessed using the eating attitudes test-26 (EAT-26).
Sample size was 16 transgender people.
AFAB and AMAB participants appeared to differ in the associations between risk of eating disorders and weight status, energy, and nutritional intake.
Results
The absolute differences in body composition measurements when male or female sex is selected on bioimpedance equipment were minimal.
Differences were below 0.8% for muscle mass depending on sex selected on the equipment.
Differences were below 1.1% for fat mass depending on sex selected on the equipment.
Body composition was assessed using electrical bioimpedance.
The authors describe this as a 'minimal impact of sex/gender selection on bioimpedance equipment in the context of a consultation.'
Results
Dietary intake and risk of eating disorders appeared to follow gender identity rather than sex assigned at birth.
Dietary intake was assessed using a semiquantitative food frequency questionnaire.
AFAB and AMAB participants seemed to differ regarding associations between risk of eating disorders and weight status, energy, and nutritional intake.
The finding applied across both AFAB and AMAB subgroups within the 16-person sample.
Authors conclude that 'individual processes and influences should be taken into account by health professionals.'
Methods
The study was an exploratory cross-sectional design with a small sample of transgender individuals in the gender transition process.
Sixteen transgender people were assessed.
62.5% (n=10) were assigned female at birth and 37.5% (n=6) were assigned male at birth.
Age range was 18 to 53 years.
Measures included risk of eating disorders, dietary intake, anthropometry, and body composition.
The authors characterize this as an 'exploratory cross-sectional study.'
