P. Hay, THE EPIDEMIOLOGY OF EATING DISORDER BEHAVIORS - AN AUSTRALIAN COMMUNITY-BASED SURVEY, The International journal of eating disorders, 23(4), 1998, pp. 371-382
Objective: The study aims were to evaluate the prevalence and distribu
tion of respective eating disorder behaviors (DSM-IV criteria) in a re
presentative community-based sample. Method: Data were obtained from 3
,001 interviews of a randomly selected sample of 4,200 individuals' (a
ge >15 years) households in South Australia. Results: Ninety-six (3.2%
) of respondents had regular current episodes of binge eating, 48 (1.6
%) regularly fasted or used strict dieting, 24 (0.8%) purged. An estim
ated 8 (0.3%) had bulimia nervosa and 30 (1%) had binge eating disorde
r. Binge eating and dieting were most common in people who were in the
ir early to mid thirties. Dieting and purging, but not regular binge e
ating, were more common in women than in men. Purging was most common
in the 35-44 year age range. The only behavior significantly associate
d with (increased) weight was binge eating. Unmarried subjects were le
ss likely to diet than married subjects. No significant differences in
rates of these behaviors were found for household income. Discussion:
Problematic eating disorder behaviors in older women and in men were
more common than expected and merit further clinical and research atte
ntion. (C) 1998 by John Wiley & Sons, Inc.
