A research team has identified factors that may increase overweight adolescents' risk of engaging in extreme weight control behaviors.
The behaviors include self-induced vomiting, the use of diet pills, laxatives, and diuretics, as well as binge eating.
Overweight youth with certain socio-environmental, psychological, and behavioral tendencies, such as reading magazine articles about dieting, reporting a lack of family connectedness, placing a high importance on weight, and reporting having participated in unhealthy weight control behaviors, are more likely to suffer from eating disorders.
Youth were surveyed at two time points; the first occurring when participants were in middle school and high school, and the second occurring five years later.
From analyzes, researchers found that disordered eating habits among overweight youth are linked to specific tendencies for both males and females, but a number of specific differences between genders were noticed.
For instance, increased hours of moderate to extreme physical activity and lower self-esteem predicted higher risk for disordered eating among females. For males, depressive symptoms, poor eating patterns, including high fast food and sweetened beverage intake, increased their risk of disordered eating.
Further exploration of these gender differences may be important in understanding who is at highest risk for developing disordered eating behaviors and whether different intervention strategies may be needed to prevent disordered eating among males and females," said Nancy Sherwood, Ph.D., assistant professor at the University of Minnesota School of Public Health and a co-author of the study.
