RESUMO

BACKGROUND: Disordered eating behaviors (DEB) impact on health and wellbeing worldwide. This study aimed to examine sociodemographic trends in the prevalence of DEB over 20 years in the Australian general population. METHODS: Data were derived from five sequential cross-sectional surveys (1998, 2008, 2009, 2016 and 2017) with population-representative samples of adults and adolescents residing in South Australia (N = 15 075). DEBs investigated were objective binge eating (OBE), strict dieting/fasting, and purging. Sociodemographic data included gender, age, educational level, work and marital status, and residence. RESULTS: OBE prevalence increased significantly. Strict dieting/fasting also increased from 1998 to 2008/9 but remained stable between 2008/9 and 2016/7. Purging prevalence did not change significantly over time. All survey years were associated with a significantly higher odds of OBE, and strict diet/fasting compared to 1998. Lower age, a higher Accessibility Remoteness Index of Australia (ARIA) score, higher body mass index (BMI), higher educational attainment, and not being in a married or de facto relationship were independently associated with greater adjusted odds for endorsing OBE. Younger age, female gender, and higher BMI were also independently associated with greater adjusted odds for endorsing strict dieting/fasting. CONCLUSIONS: The increased prevalence of DEBs in various strata of Australian society has both public health and clinical implications. The results refute the stereotype that eating disorders (EDs) predominantly affect young women. They build impetus for future research on EDs among men and older individuals, with a view to developing tailored public health and clinical interventions for these populations.

RESUMO

PURPOSE: The association between binge eating and obesity is increasing. Treatments for disorders of recurrent binge eating comorbid with obesity reduce eating disorder (ED) symptoms, but not weight. This study investigated the efficacy and safety of introducing a weight loss intervention to the treatment of people with disorders of recurrent binge eating and a high body mass index (BMI). METHODS: A single-blind randomized controlled trial selected adults with binge eating disorder or bulimia nervosa and BMI ≥ 27 to < 40 kg/m2. The primary outcome was sustained weight loss at 12-month follow-up. Secondary outcomes included ED symptoms. Mixed effects models analyses were conducted using multiple imputed datasets in the presence of missing data. RESULTS: Ninety-eight participants were randomized to the Health Approach to Weight Management and Food in Eating Disorders (HAPIFED) or to the Cognitive Behavioural Therapy-Enhanced (CBT-E). No between-group differences were found for percentage of participants achieving weight loss or secondary outcomes, except for reduction of purging behaviour, which was greater with HAPIFED (p = 0.016). Binge remission rates specifically at 12-month follow-up favoured HAPIFED (34.0% vs 16.7%; p = 0.049). Overall, significant improvements in the reduction of ED symptoms were seen in both groups and these were sustained at the 12-month follow-up. CONCLUSION: HAPIFED was not superior to CBT-E in promoting clinically significant weight loss and was not significantly different in reducing most ED symptoms. No harm was observed with HAPIFED, in that no worsening of ED symptoms was observed. Further studies should test approaches that target both the management of ED symptoms and the high BMI. LEVEL OF EVIDENCE: Level I, randomized controlled trial TRIAL REGISTRATION: US National Institutes of Health clinical trial registration number NCT02464345, date of registration 1 June 2015.
