Objective To evaluate the relationship between body size and depressive symptoms, as well as the moderating effects of age. sex, and socioeconomic status I in a sample of voting adolescents. Study design The study group comprised 678 young adolescents (age 11 to 14 years). Body mass index (BMI) z scores were used to estimate body size. Depression symptoms were assessed using the Children's Depression Inventory I The spline function was used to examine the shape of the relationship between BMI z score and depressive symptoms. Results In the total sample, CDI scores were lowest for BMI z scores between -1 and -0.5. CDI scores increased progressively for BMI z scores > 0. In boys, CDI scores increased for BMI z scores > 2, whereas in girls, CDI scores increased for BMI z scores > -0.5 and < -1. Age did not have a significant moderating effect. SES had a moderating effect only in boys (P = .011). Conclusions The relationship between body size and depressive symptoms in young adolescents is curvilinear and is moderated by sex. Heavier-than-average and underweight girls, as well as obese boys, had the highest depression scores. (J Pediatr 2009;154:86-90)
