AbstractThis paper considers the impact of pubertal status and pubertal timing on disordered eating in Irish adolescents. 1190 boys and 1841 girls completed the Eating Attitudes Test‐26, the Eating Disorder Inventory‐III and self‐report measures of pubertal status and pubertal timing. Regarding pubertal status, greater maturity in girls was associated with increased overall eating concerns, higher drive for thinness and higher levels of body dissatisfaction. In boys, greater maturity was associated with lower drive for thinness and lower body dissatisfaction. Regarding pubertal timing, early‐maturing girls showed the most eating concerns, the highest drive for thinness, scored highest on bulimic symptoms and were the most dissatisfied with their bodies. In contrast, late‐maturing boys had more bulimic symptoms and more dissatisfaction with their bodies than on‐time peers. The findings suggest that puberty itself is a risk factor for disordered eating for girls rather than boys; however, pubertal timing is a risk factor for both.
