To analyze the influence of socioeconomic status on the prevalence, evolution and incidence of obesity between the ages of 12 y and 15 y in Belgium.
Retrospective cohort study.
2607 children from five social groups.
The body mass index (BMI) measured during two school medical examinations carried out at an interval of two years between the ages of 12 y and 15 y.
Between the ages of 12 y and 15 y the inverse relation between social status and the prevalence of obesity is accentuated in girls. The increasing divergence between social groups was a result both of the greater incidence of new cases of obesity and the reduced improvement rate in obesity already present in adolescents of lower social classes.
Social inequalities in obesity increase during early adolescence. Preventive measures, targeting children of low socioeconomic status, should be put in place at this stage of life.
分析社会经济地位对比利时12至15岁青少年肥胖患病率、演变及发病率的影响。
回顾性队列研究。
来自五个社会群体的2607名儿童。
在12至15岁期间间隔两年进行的两次学校体检中测量的体重指数（BMI）。
在12至15岁之间，女孩中社会地位与肥胖患病率之间的反比关系更为明显。社会群体之间差异的扩大是肥胖新发病例发生率更高以及社会阶层较低的青少年中已有肥胖症改善率降低这两个因素共同作用的结果。
肥胖方面的社会不平等在青春期早期会加剧。应在生命的这个阶段针对社会经济地位较低的儿童采取预防措施。
