目的：比较世界卫生组织（WHO）基于不同文化健康最佳喂养儿童的新标准与国际国家卫生统计中心（NCHS）/WHO参考文献之间儿童营养状况和消瘦、发育迟缓和体重不足患病率的差异，使用第一轮纵向小组研究的经验数据。材料和方法：三个横截面的数据集从年轻的生活纵向研究进行了分析，从印度（安得拉邦），秘鲁，越南。大约在2000年，每个国家6至17.9个月大的儿童被称重和测量。使用新的WHO生长标准计算身高别体重、年龄别体重和年龄别身高的平均z评分以及消瘦、发育迟缓和体重不足的患病率，并与使用NCHS/WHO参考计算的结果进行比较。与NCHS参考值相比，所有国家的平均身高体重和年龄体重z得分均较高，平均年龄身高z得分相似，根据WHO标准。在所有3个国家，与NCHS相比，年龄别体重的平均z评分更接近于零，表明世卫组织标准曲线更好地反映了这些人群的体重增长模式。按照世卫组织的标准，消瘦在印度和秘鲁更为普遍，但在越南则不那么普遍。在所有3个国家的儿童发育迟缓的比例较高，更少的儿童被归类为weight.Conclusions：使用新的WHO标准导致的差异，平均z分数的体重为长度和体重为年龄和变化的流行浪费，发育迟缓，体重不足。差异的方向和大小不一致。
Objective: To compare differences in child nutritional status and the prevalence of wasting, stunting, and underweight between the new World Health Organization (WHO) standards based on healthy optimally fed children from different cultures and the international National Centre for Health Statistics (NCHS)/WHO references using empirical data from the first round of a longitudinal panel study.Materials and Methods: Three cross-sectional data sets from the Young Lives longitudinal study were analysed from India (Andhra Pradesh state), Peru, and Vietnam. Around 2000, children between 6 and 17.9 months old from each country were weighed and measured. Mean z scores for weight-for-length, weight-for-age, and length-for-age-and the prevalence of wasting, stunting, and underweight-were calculated using the new WHO growth standards and compared with the results calculated using NCHS/WHO references.Results: Compared with the NCHS reference, the mean weight-for-length and weight-for-age z scores for all countries were higher, and the mean length-for-age z scores were similar, using the WHO standards. The mean z score for weight-for-age was closer to zero, compared with NCHS, in all 3 countries, indicating that the WHO standard curves better reflect the pattern of ponderal growth in these populations. Using WHO standards, wasting was more prevalent in India and Peru but less prevalent in Vietnam. In all 3 countries a higher proportion of children were stunted and fewer children classified as underweight.Conclusions: Using the new WHO standards resulted in differences in mean z scores for weight-for-length and weight-for-age and changes in the prevalence of wasting, stunting, and underweight. The direction and magnitude of difference are not consistent.
