Eating disorder causes serious disturbances in behaviors related to nutrition in adolescent. Although most of these attitudes are benign, they can bear significant psychological and health risks. A cross-sectional study was conducted on 250 university adolescent girls studying in Peshawar Pakistan to explore their eating disorder, nutritional and health status. Girls were interviewed for eating attitudes by using Eating Attitude Test (EAT-26), socio-economic status and body image. Anthropometric and biochemical indices were measured. Based on EAT-26 scale, girls with and without eating disorders were identified. In both groups the association between anemia and risk factors was evaluated. Health and nutritional risk factors for anemia in girls were identified by applying logistic regression. Mean score of EAT-26 was 18±10.5 while for Dieting, Bulimia, Oral Control and Body Image of the girls was 8.5±7, 3.20±2.59, 6.36±4.41 and 20±9 respectively. EAT-Score was found in strong association with anemia in unadjusted and adjusted analysis. Among the health factors, girls with symptoms of anxiety, depression and stress were more likely anemic than their counterpart. More anorexic girls were found overweight and obese in comparison to the rest (p<0.05). Body shape being android or gynoid as well as anemia were found similar among the groups (p>0.05). More anorexic girls showed significant difference in less freshness, disrupted sleep and low physical activity (p<0.05). It has been concluded that eating disorders (anorexia) are more prevalent in university adolescent girls and could adversely affect the health and nutritional status of the students.
