School-aged children gain weight most rapidly in summer, but few studies have investigated summer weight gain among preschool-aged children. We fit continuous linear spline mixed models to test for accelerated summer weight gain among 2,044 children attending 16 Boston-area Head Start programs between fall 2016 and spring 2019. Academic year and summer rates of change in modified body mass index z-score differed (P < .001), with accelerated summer weight gain most pronounced among children with obesity. As with school-aged children, increased focus on the summer is warranted for promoting healthy weight among children in Head Start.
学龄儿童在夏季体重增加最为迅速，但很少有研究调查学龄前儿童的夏季体重增加情况。我们采用连续线性样条混合模型，对2016年秋季至2019年春季期间在波士顿地区16个“启智计划”项目中就读的2044名儿童的夏季体重加速增加情况进行了测试。学年和夏季修正体重指数z评分的变化率存在差异（P <.001），夏季体重加速增加在肥胖儿童中最为明显。与学龄儿童一样，为促进“启智计划”项目中儿童的健康体重，有必要更多地关注夏季。
