海南省少数民族地区婴儿生长发育水平调查

Physical development of infants in regions of minority ethnic group in Hainan province

目的：了解海南省少数民族地区婴儿生长发育水平，为制定儿童营养改善计划提供科学依据。方法：选择4个少数民族聚居市县，每个县（市）随机抽取30～40个自然村进行婴儿身长、体重测量调查，与WHO儿童生长发育标准进行比较并计算生长迟缓率和低体重率。结果：婴儿身长、体重均在4个月左右开始落后于世界卫生组织推荐标准，且落后幅度随月龄增加而加大。婴儿发育迟缓率为9．8％，其中小于6个月婴儿组为6．0％，6个月及以上组为13．4％。低体重率为11．6％，小于6个月组为5．5％，6个月及以上婴儿为17．2％。结论：海南省少数民族地区婴儿发育水平从4个月左右开始落后于正常值，低体重率和发育迟缓率较高，应加强喂养知识的宣传教育，提高婴儿发育水平。

Objective： To investigate the physical development of infants in regions of minority ethnic group in Hainan province and provide scientific evidence for the make of plan of children＇s nutrition improving. Methods： The study was conducted in 4 minority ethnic counties. 30 ～ 40 villages in each county were selected randomly.

Results： By the standards recommended by WHO, The growth level of infants The results were combody underweight were began to slowdown from about 4 months of age, and with time passing, the gap increased correspondingly. The overall retardation rate was 9.8% , of which, 6.0% for infants younger than 6 months and 13.4% for infants of 6 months or over. The overall rate of body underweight was 11.6% , of which, 5.5% for infants younger than 6 months and 17.2% for infants of 6 months or over. Conclusion ： Infants growth level falls below the standards recommended by WHO at age of 4 months old in regions of minority ethnic group in Hainan province, with higher retardation rate and rate of body underweight. Knowledge of infant feeding should be popularized and strengthened, to improve the growth and development levels of infants.
