Identifying Risk Factors for Disordered Eating among Female Youth in Primary Care

Socio-Cultural Standards Promoted by the Mass Media as Predictors of Restrictive and Bulimic Behavior

Research lacks in verifying the nature of the relationship between mass media pressure, body image, and the risk of unhealthy eating behaviors. This study aimed to investigate whether the internalization of sociocultural norms, perceived pressure or searching for information about body image promoted by the mass media directly affect restrictive and bulimic behavior toward eating, through the mediating role of body image and physical appearance variables. The research hypotheses were that (1, 2) body image, the pressure and the internalization of sociocultural norms are significant predictors of unhealthy eating behavior among women and men; and (3) the variables related to body image play the role of the mediating variable between the impact of socio-cultural standards of body image promoted by the mass media and unhealthy eating behavior. The sample comprised 514 Polish men and women, aged 16 to 63 old (men M=24.35; SD=13.53; women M=24.77; SD=7.61), with average Body Mass Index (BMI). Assessment comprised the Sociocultural Attitudes Toward Appearance Scale (SATAQ-3), Eating Disorders Inventory (EDI 3), The Multidimensional Body-Self Relations Questionnaire (MBSRQ-AS), and the author's survey questionnaire. The descriptive and comparative statistics, and a path analysis (structural equations modeling) were applied. The statistical analysis showed that the variables related to body image do not play the role of intermediary variables. The pressure of sociocultural standards of body image and physical appearance had the strongest and most direct effect on the development of restrictive eating behavior and appeared to negatively affect body image in women. The search of information on body image in the mass media had the strongest and most direct impact on the development of bulimic eating behavior among women. However, only the global internalization of sociocultural standards of body image and physical appearance had a significant and direct effect on the development of bulimic eating behavior in men. Moreover, the internalization of athletic body shape standards had the strongest and most positive impact on some aspects of body image in this group. No sociocultural variables showed a direct impact on restrictive behavior among studied men. BMI had a positive and direct impact on individual body part satisfaction. These results may help improve prevention of eating disorders and dysfunctional eating behavior.

Disordered Eating Behaviours and Eating Disorders in Women in Australia with and without Polycystic Ovary Syndrome: A Cross-Sectional Study

Psychological co-morbidities common in polycystic ovary syndrome (PCOS) may contribute to disordered eating and subsequent weight gain. This cross-sectional study aimed to determine the prevalence of disordered eating and a range of eating disorders and demographic risk factors associated with these behaviours within an Australian group of women with and without PCOS. Data from 899 women with (n = 501) and without (n = 398) PCOS were analysed as possibly indicative of disordered eating or eating disorders using the Eating Disorder Examination Questionnaire (EDE-Q) and The Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) criteria. Disordered eating (p = 0.012) but not eating disorders (p = 0.076) were more prevalent in women with PCOS compared to controls. Increased body mass index (BMI) [Odds Ratio (OR): 1.03; 95%; Confidence Interval (CI): 1.01, 1.05, p = 0.012] and older age [OR: 1.05; 95%CI: 1.02, 1.08, p = 0.002] but not PCOS diagnosis [OR: 1.43; 95%CI: 0.96, 2.13 p = 0.078] increased the odds of disordered eating. Increased BMI [OR: 1.04; 95%CI: 1.02, 1.06, p < 0.001] and younger age [OR: -0.95; 95%CI: 0.93–0.95, p < 0.001] but not PCOS diagnosis [OR: 1.38; 95%CI: 0.97, 1.95, p = 0.076] increased the odds of an eating disorder. Clinicians are recommended to screen all women with PCOS for possible disordered eating behaviours, with particular attention to women with elevated BMI.
