摘要

Objective: To investigate the association between family, teachers and peer support patterns on gaps in adolescent's weight perceptions. Design: A cross-sectional, school-based survey collected information on weight and height, weight perception, socio-economic and family characteristics and social support. Principal component analysis (PCA) was performed to capture social support patterns (SSP). Multivariable logistic regression was used to model adolescent weight perception, including SSP adjusted for demographic variables. Setting: The 2014 Israeli Health Behaviours in School-Aged Children (HBSC) survey. Participants: Adolescents aged 11-18 years (n 7563). Results: In total, 16 center dot 1 % of the boys and 10 center dot 7 % of the girls were overweight or obese. Most participants perceived their size accurately. Body size was underestimated by 25 center dot 6 % of the boys and 15 center dot 1 % of the girls, while 15 center dot 2 % of the boys and 27 center dot 7 % of the girls overestimated their body size. PCA generated three SSP accounting for 81 center dot 9 % of the variance in social support. Female sex and higher SES increased odds of overestimating body size. Students in the top quartile (Q4 v. Q1-Q3) of family support and teacher support were less likely to overestimate their body size. Good parental communication reduced the odds of body size overestimation in middle school students. Male sex and higher family support increased odds of underestimation. Conclusions: Significant support from parents and teachers was associated with accurate weight perceptions; thus, support skills may be amenable to intervention. Efforts should be made to educate adolescents on healthy weight.
