对非肥胖学龄儿童青少年肥胖进行预防性干预的有效时间尚不清楚。本研究的目的是检查每年的身体质量指数（BMI）的增长对青少年肥胖的发展在6岁的非肥胖的日本children.MethodsLongitudinal体重和身高数据，每年收集9723名6-14岁的儿童，和个人每年的BMI增长进行了计算。BMI ≥每个年龄和性别定义的肥胖的第95百分位数。在6岁的非肥胖儿童中，Logistic回归分析被应用于将每个年龄段的年度BMI增加与最终调查时的肥胖相关联。ResultsThe 6岁的非肥胖儿童在最终调查时变得肥胖，与同龄人相比，他们在任何年龄段的年度BMI增加都比基线BMI大。每年BMI增加，即使在学龄早期，也会增加青少年肥胖的风险。分类分析还显示，6-7岁儿童的BMI年增长高于平均值1-SD，有显著的青少年肥胖风险（OR：男孩4.39 [95%CI：2.98-6.46]，男孩3.83 [95%CI：结论：在任何学龄期，BMI的年增长量越大，对6岁非肥胖儿童（无关键期）来说，青春期肥胖的风险越大。这表明需要使用年度BMI增量进行早期和持续的基于学校的监测，以预防青少年肥胖发展的干预。
BackgroundEffective timing of preventive intervention for adolescent obesity in non‐obese school‐aged children remains unclear. The aim of this study was to examine the impact of annual body mass index (BMI) gain on the development of adolescent obesity in 6‐year‐old non‐obese Japanese children.MethodsLongitudinal weight and height data were collected annually from 9723 children aged 6–14 years, and individual per‐year BMI gains were calculated. The BMI ≥ the 95th percentile for each age and sex defined obesity. In 6‐year‐old non‐obese children, logistic regression analyses were applied to correlate the annual BMI gain at each age with obesity at a final survey.ResultsThe 6‐year‐old non‐obese children who became obese at a final survey showed larger annual BMI gains at any age compared with their peers with respect to baseline BMI. Increases in annual BMI gain, even in early school age, raised the risk of adolescent obesity. Categorical analysis also showed that children aged 6–7 years with higher annual BMI gains than 1‐SD above the mean had a significant risk for adolescent obesity (OR: 4.39 [95%CI: 2.98–6.46] in boys and 3.83 [95%CI: 2.60–5.63] in girls, respectively).ConclusionsA larger annual BMI gain at any school age is a risk for adolescent obesity in 6‐year‐old non‐obese children with no critical period. This suggests the need for earlier and continuous school‐based surveillance using annual BMI gain for preventive intervention of adolescent obesity development.
