Eating disorders have been widely studied among civilian women and among select groups of men (athletes and wrestlers). Gross disturbances in eating behaviors characterize the conditions of anorexia nervosa (AN), currently seen among 1 to 2% of non-active duty women. Bulimia nervosa (BN) is prevalent among 2% of the female population, and both disorders have a female-to-male ratio of 10:1. Another category of eating disorders known as not otherwise specified (NOS) occurs in between 3 and 35% of the population according to the reported literature. This study examined the prevalence of AN, BN, and NOS among a large sample of active duty Navy men. Multiple military, professional, and behavioral were analyzed to promote an increased understanding and awareness of these disorders among active duty men. This was a descriptive, correlational study among 4,800 Navy men targeted from hospitals, clinics, and ships at sea. Anonymous surveys were returned by 28% of prospective subjects (N = 1,425). The study revealed a prevalence of 2.5% for AN, 6.8% for BN, and 40.8% for NOS among active duty Navy men. AN and BN existed without difference among all active duty men regardless of rank/rate, job assignment, or age. Use of laxatives, diuretics, diet pills, vomiting, and fasting for standards increased during the body measurement and fitness periods, but year-round use of these methods existed at disturbing rates. Multiple logistic regression analysis predicted several factors that might predict the manifestation of eating disorders in this population of active duty members.

Eating disorders continue to be studied among civilian women. Gross disturbances in eating behaviors characterize the condition of anorexia nervosa (AN), currently seen among 1 to 2% of non-active duty women. Bulimia nervosa (BN) is prevalent among 2% of the female population, and both disorders have a female-to-male ratios of 10:1. Another category of eating disorders known as not otherwise specified (NOS) occurs in 3 to 35% of individuals in the reported literature. This study examined the prevalence of AN, BN, and NOS among a large sample of active duty women currently serving in the Army, Navy, Air Force, and Marines. Multiple military, professional, and behavioral variables were analyzed to provide an increased understanding and awareness of these disorders among all active duty service women. This descriptive, correlational study of 3,613 service women targeted females from the total population of three major medical centers (Army, Navy, and Air Force) and the total population of Marine women serving in Okinawa, Japan, at the time of the study. Anonymous survey return was obtained at 34% (N = 1,278). The study revealed an overall prevalence of 1.1% for AN, 8.1% for BN, and 62.8% for NOS among all service women. However, AN, BN, and NOS were found at significantly higher rates (p = 0.000) among women in the Marines, who reported AN at 4.9%, BN at 15.9%, and NOS at 76.7%. Use of laxatives, diuretics, diet pills, vomiting, and fasting for standards increased during the body measurement and fitness periods for all services, but year-round use of many of these behaviors occurred at significantly higher rates among Marines (p = 0.000). Multiple logistic regression analysis predicted several factors associated with the manifestation of eating disorders in this population of active duty women.

The aim of this paper was to explore the relationships between depressive symptoms and weight control strategies in DSM-IV eating disordered patients with binge eating behaviours. We hypothesised that weight control strategies characterised by a loss of control, such as vomiting and purging, may be clinically associated with increased levels of depression. The study population consisted of 402 consecutive outpatients: 27 with binge eating/purging anorexia nervosa (AN-BN), 213 with purging bulimia nervosa (BN-P), 73 with non-purging bulimia nervosa (BN-NP), and 89 with binge eating disorder (BED). The severity of depression was measured using the Beck Depression Inventory (BDI), and binge eating behaviours were investigated using the self-report scale for bulimic behaviours. In the sample as a whole, the severity of depression significantly correlated with the severity of binge eating behaviours, but no significant differences were found in the severity of depression by diagnostic sub-types. In order to avoid the confounding erasing effect of time, a smaller sample of patients with a short history of binge eating behaviours was further explored. Furthermore, because weight control strategies and the eating disorder diagnostic sub-types overlapped imperfectly, the patients were compared on the basis of presence or absence of strategies reflecting an active attempt to master the weight gain due to bingeing behaviours. The patients adopting active control strategies (N = 14) had significantly less severe depressive symptoms than those adopting non-active weight control strategies (N = 39). Finally, the Authors discuss some hypotheses concerning the defensive role of weight control strategies and the impact of illness duration on the clinical expression of depression in eating disordered patients.
