It is important to update weight-for-length/height growth curves in China and re-examine their performance in screening malnutrition.
To develop weight-for-length/height growth curves for Chinese children and adolescents.
A total of 94 302 children aged 0-19 years with complete sex, age, weight and length/height data were obtained from two cross-sectional large-scaled national surveys in China. Weight-for-length/height growth curves were constructed using the LMS method before and after average spermarcheal/menarcheal ages, respectively. Screening performance in prevalence estimates of wasting, overweight and obesity was compared between weight-for-height and body mass index (BMI) criteria based on a test population of 21 416 children aged 3-18.
The smoothed weight-for-length percentiles and Z-scores growth curves with length 46-110 cm for both sexes and weight-for-height with height 70-180 cm for boys and 70-170 cm for girls were established. The weight-for-height and BMI-for-age had strong correlation in screening wasting, overweight and obesity in each age-sex group. There was no striking difference in prevalence estimates of wasting, overweight and obesity between two indicators except for obesity prevalence at ages 6-11.
This set of smoothed weight-for-length/height growth curves may be useful in assessing nutritional status from infants to post-pubertal adolescents.
更新中国身长/身高别体重生长曲线并重新审视其在筛查营养不良方面的表现十分重要。
制定中国儿童和青少年的身长/身高别体重生长曲线。
从中国两项大规模横断面全国性调查中获取了总共94302名0至19岁儿童的完整性别、年龄、体重和身长/身高数据。分别在平均遗精/初潮年龄前后使用LMS方法构建身长/身高别体重生长曲线。基于21416名3至18岁儿童的测试人群，比较了身高别体重和体重指数（BMI）标准在消瘦、超重和肥胖患病率估计中的筛查表现。
建立了两性身长46至110厘米的身长别体重百分位数和平滑Z分数生长曲线，以及男孩身高70至180厘米、女孩身高70至170厘米的身高别体重生长曲线。身高别体重和年龄别BMI在各年龄性别组筛查消瘦、超重和肥胖方面具有很强的相关性。除6至11岁肥胖患病率外，两个指标在消瘦、超重和肥胖患病率估计方面没有显著差异。
这套平滑的身长/身高别体重生长曲线可能有助于评估从婴儿到青春期后青少年的营养状况。
