比较使用标准程序（即，将体重指数（BMI）百分位数与年龄匹配的英国参考数据进行比较）与根据成熟状态调整的方法（即，相对于生物学年龄匹配）对英国儿童队列的体重分类。从英国小学儿童的观察性研究中收集的数据分析。学校位于英格兰西南部。407名9-11岁儿童（98%为白色英国人）。使用BMI百分位数对体重状态进行分类，使用（1）性别和实足年龄匹配的参照物和（2）性别和生物学年龄匹配的参照物（基于预测成人身高的%）相对于UK 1990参考生长图表。对于这两种方法，如果儿童体重>第2百分位数且<第85百分位数，则将其归类为正常体重，如果第85百分位数且<第95百分位数，则将其归类为超重，如果≥第95百分位数，则将其归类为肥胖。51名儿童（12.5%）超重，另外51名肥胖（12.5%）根据标准的时间年龄匹配分类。根据成熟度进行调整后，32%的超重女孩和15%的超重男孩被重新归类为正常体重，11%和8%的肥胖女孩和男孩被重新归类为超重。早熟儿童从超重重新分类为正常体重的可能性是“按时”成熟者的4.9倍（OR 95%CI 1.3至19）。将成熟状态评估纳入体重分类导致早熟青少年分类的显着变化。需要进一步研究探索客观健康风险和福祉的影响。
To compare the weight categorisation of a cohort of UK children using standard procedures (ie, comparing body mass index (BMI) centiles to age-matched UK reference data) versus an approach adjusted for maturation status (ie, matching relative to biological age). Analysis of data collected from an observational study of UK primary school children. Schools in South West England. Four hundred and seven 9–11 year-old children (98% white British). Weight status was classified using BMI centiles using (1) sex and chronological age-matched referents and (2) sex and biological age-matched referents (based on % of predicted adult stature) relative to UK 1990 reference growth charts. For both approaches, children were classified as a normal weight if >2nd centile and <85thcentile, overweight if 85th and <95thcentiles, and obese if ≥95thcentile. Fifty-one children (12.5%) were overweight, and a further 51 obese (12.5%) according to standard chronological age-matched classifications. Adjustment for maturity resulted in 32% of overweight girls, and 15% of overweight boys being reclassified as a normal weight, and 11% and 8% of obese girls and boys, respectively, being reclassified as overweight. Early maturing children were 4.9 times more likely to be reclassified from overweight to normal weight than ‘on-time’ maturers (OR 95% CI 1.3 to 19). Incorporating assessments of maturational status into weight classification resulted in significant changes to the classification of early-maturing adolescents. Further research exploring the implications for objective health risk and well-being is needed.
