目的了解广州市0～3岁儿童营养状况,为营养指导和干预提供依据。方法采用两阶段分层整群抽样,抽取广州市城、乡、男、女儿童共10 346名进行体格发育调查,采用以基于WHO标准的Z评分评价儿童的营养状况。结果广州市0～3岁儿童低体重发生率为2.57%,生长发育迟缓率为3.37%,消瘦率为2.54%,肥胖率为2.50%。低体重率和生长发育迟缓率随年龄的增长而增加。郊区儿童、男童的营养不良率分别高于城区儿童和女童,男童的肥胖率分别高于女童。结论广州市0～3岁儿童营养不良和营养过剩现象同时存在。郊区儿童的营养不良和男童的营养失衡应引起关注。
Objective To understand the nutritional status of children aged 0 ~ 3 in Guangzhou and provide the basis for nutritional guidance and intervention. Methods A total of 10 346 children in urban, rural, males and females in Guangzhou were enrolled in this study. Two-stage stratified cluster sampling was used to conduct physical development survey. Z-scores based on the WHO criteria were used to evaluate children’s nutritional status. Results The prevalence of low birth weight was 2.57%, the growth retardation rate was 3.37%, the wasting rate was 2.54% and the obesity rate was 2.50% in 0-3 years old children in Guangzhou. Low body weight and growth retardation rates increase with age. Malnourishment rates among suburban children and boys were higher than those for urban children and girls, respectively, and boys’s obesity rates were higher than girls’ respectively. Conclusions Malnutrition and overnutrition in 0-3 years old children in Guangzhou exist simultaneously. Malnutrition among children in the suburbs and boys’ nutritional imbalance should be of concern.
