---|---|---|---|---|
% | n | % | n | |
Dietary restraint | 23 | 227 | 7.4 | 73 |

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 [20–22, 24, 25, 28–30]
