The effect of inpatient psychiatric hospitalization on weight gain in children and adolescents.

Abstract

Measures of weight were obtained both at admission and at discharge for children and adolescents receiving inpatient services at a private psychiatric hospital. The sample included 20 males and 20 females from each of three units: child psychiatric, adolescent psychiatric, and adolescent substance abuse. The difference between the actual weight change of the subjects and the weight change predicted from growth charts was obtained. Overall, subjects gained a significant amount of weight. The actual mean increase in weight was roughly 3.5 times greater than the predicted increase, and there were no significant differences in weight gain between males and females among patients from each of the three units. Potential explanations for this increase in weight are explored, and the implications are discussed.
