Table 4 Comparisons of any and regular occurrences of disordered eating behaviors between gender-expansive participants assigned male sex at birth (AMAB) and those assigned female sex at birth (AFAB)

From: Community norms for the Eating Disorder Examination Questionnaire (EDE-Q) among gender-expansive populations

  Any occurrence (%) Regular occurrence (%)

  1. Any occurrence was defined as ≥1 episode in the past 28 days. Regular occurrence of dietary restraint was defined as going for long periods of time (≥8 h) without eating anything to influence shape or weight for ≥13 days over the past 28 days. Regular occurrence of excessive exercise was defined as exercising in a driven or compulsive way as a means of controlling weight, shape or amount of fat, or burning off calories for ≥20 days over the past 28 days. For all other behaviors (objective binge episodes, self-induced vomiting, and laxative misuse), regular occurrence was defined as ≥4 occurrences over the past 28 days. Definitions for any and regular occurrence are consistent with previously published EDE-Q norms studies [20,21,22, 24, 25, 28,29,30]
