Biopsychosocial and Physical Correlates of Middle School Boys’ and Girls’ Body Satisfaction

Abstract

Boys (n = 629) and girls (n = 659) in grades 6 through 8 in the U.S. completed self-report measures of pubertal development, weight pressures, internalization, social appearance comparison, self-esteem, depression, and physical self-concept, and objective measures of cardiorespiratory fitness and BMI. Regression analyses revealed that gender moderated the strength of the relationships between the variables and body satisfaction (girls—Adj. R2 = .49; boys—Adj. R2 = .20), though BMI, pressures, physical self-concept, and self-esteem were related significantly for each gender. Girls were most affected by pressures related to weight loss, whereas gaining weight and musculature was most salient for boys. Future research needs to examine longitudinally how these variables contribute to the development of body satisfaction.
