Background: Children’s eating behaviors, body shape and body image cognition may be more susceptible to the influence of their parents, but these influences may be weakened with age. There may be different association pathways between parental pressure on children’s body image (PPCBI), body mass index (BMI), body image dissatisfaction (BID) and eating disorders (EDs) among children and adolescents at different developmental stages.
Methods: The stratified cluster sampling method (Stratified by grade, and took the classes as clusters) was used to select 486 students aged 8– 15 years in two 9-year schools. Children’s body height, weight, testicular volume and breast development were measured. PPCBI, BID, and EDs were investigated using the Appearance-related Social Stress Questionnaire, Body Size Questionnaire (BID-14), and EDI-1 scale, respectively.
Results: The boys before puberty initiation had significantly higher EDs score (182.3± 50.8) than girls before puberty initiation (164.1± 58.1) (P < 0.05). There were significant association pathways of PPCBI→BMI→BID→EDs and PPCBI→BID→EDs in boys before puberty initiation (β =0.035, P < 0.05 0.01; β =0.059, P < 0.01), in boys after puberty initiation (β =0.032, P < 0.01; β =0.175, P < 0.001), and in girls after puberty initiation (β =0.026, P < 0.01; β =0.172, P < 0.001). There was a positive association pathway of PPCBI→EDs in boys before puberty initiation (β =0.30, P < 0.001) and PPCBI→BID→EDs in girls before puberty initiation (β =0.176, P < 0.01).
Conclusion: Parental pressure on children’s body image may positively associate with children’s eating disorders through BMI and body image dissatisfaction in boys and girls after puberty initiation and directly associate with eating disorders in boys before puberty initiation; however, it may indirectly associate with eating disorders only through BID in girls before puberty initiation.
