Research on binge eating indicates that binges typically occur at times of stress, often in the evening. The relationship between sexual abuse and purging The data did not find a significant relationship between sexual abuse and purging when individual, familial, and extra-familial variables were included in the logistic regression. Unlike most earlier studies that focused on clinical samples, this study drew from a larger, more representative sample of female adolescents. The identification of significant predictors of purging at the individual, familial, and extra-familial levels suggests the importance of examining multiple levels of the teen's ecology for factors that may influence this behavior. Osteoporosis and eating disorders.
Osteoporosis is a common complication of anorexia nervosa.
Multiple factors increase risk, including decreased body weight and fat content, elevated cortisol levels, inadequate vitamin D and calcium intake, and amenorrhea and hypoestrogenemia. There is both decreased bone formation and increased bone resorption in the osteoporosis of anorexia nervosa. Unlike postmenopausal osteoporosis, estrogen replacement does not prevent or correct the osteoporosis that occurs in anorexia nervosa. Patients with bulimia nervosa or an eating disorder not otherwise specified may also be at risk of osteoporosis, especially if they have had a prior episode of anorexia nervosa. A recently released survey by an Orem-based foundation indicates that up to 35 percent of Utah County high school students have attitudes about food that put them at risk to develop an eating disorder.
