To determine whether there is an association between body mass index (BMI) and body esteem in young overweight and obese urban children, and to test peer relationship difficulties and perceived physical health as mediators of this relationship.
Child self-reported body esteem, and parent-reported child peer relationship difficulties (being bullied by peers and peer rejection) and physical health perceptions were obtained from 218 overweight and obese children aged 5-7 years (81% racial/ethnic minority, M BMI = 25.3) and their primary caregivers.
Higher BMI was associated with lower body esteem for both girls and boys. This relation was mediated by poor physical health for boys but not for girls. Peer relationship difficulties did not mediate the observed association between BMI and body esteem in either group; however, girls with higher BMI experienced more bullying and being bullied by peers was associated with lower body esteem in girls.
Intervening with perceptions of physical health may buffer overweight and obese boys from developing low body esteem in early childhood.
确定城市超重和肥胖儿童的体重指数（BMI）与身体自尊之间是否存在关联，并检验同伴关系困难和感知到的身体健康作为这种关系的中介作用。
从218名5至7岁的超重和肥胖儿童（81%为少数种族/族裔，平均BMI = 25.3）及其主要照顾者那里获取儿童自我报告的身体自尊、父母报告的儿童同伴关系困难（被同伴欺负和被同伴拒绝）以及身体健康感知情况。
较高的BMI与男孩和女孩较低的身体自尊均相关。这种关系在男孩中由较差的身体健康介导，但在女孩中并非如此。同伴关系困难在两组中均未介导观察到的BMI与身体自尊之间的关联；然而，BMI较高的女孩经历了更多的欺负，且被同伴欺负与女孩较低的身体自尊相关。
干预对身体健康的认知可能会缓冲超重和肥胖男孩在幼儿期出现低身体自尊的情况。
