目标.为了监测体重状况的年度变化，我们通过纵向的以学校为基础的监测来确定学龄儿童超重的发生率和缓解率。我们估计了在马萨诸塞州剑桥公立学校就读的学生的体重状况的1年变化。体育教师每年测量身高和体重。通过多变量logistic回归估计校正后的优势比（OR），解释了多年来对单个儿童的重复观察。1年超重发生率为4%，缓解率为15%。在超重儿童中，85%的人在1年随访时仍然超重，而18%有超重风险的儿童变得超重。7 ~ 8岁儿童超重发生率高于11 ~ 13岁儿童（男孩：OR= 1.68; 95%CI =1.14，2.47;女孩：OR =1.86; 95%CI =1.25，2.77）。发病率和缓解率在年龄较小的儿童中均较高。有超重风险的儿童比那些已经超重的儿童更有可能改变他们的体重状况。我们的研究结果支持将超重预防工作针对年幼儿童和有超重风险的儿童。
Objectives. To monitor annual changes in weight status, we determined incidence and remission rates of overweight among school-aged children with longitudinal school-based surveillance.Methods. We estimated 1-year changes in weight status among students enrolled in public schools in Cambridge, Mass. Physical education teachers measured height and weight annually. Adjusted odds ratios (ORs) were estimated via multivariate logistic regression, accounting for repeated observations of individual children across years.Results. The 1-year incidence of overweight was 4%, and the remission rate was 15%. Among overweight children, 85% remained overweight at a 1-year follow-up, while 18% of children at risk for overweight became overweight. Overweight incidence rates were higher among children aged 7 and 8 years than among those aged 11 to 13 years (boys: OR= 1.68; 95% confidence interval [CI]=1.14, 2.47; girls: OR =1.86; 95% Cl =1.25, 2.77).Conclusions. Both incidence and remission rates were higher among younger children. Children who were at risk for overweight were more likely to change their weight status than those who were already overweight. Our results support targeting overweight prevention efforts toward younger children and children at risk for overweight.
