目的:探寻中国西部农村婴儿4个月内喂养方式和营养不良的相关性。方法:选取“2006年中国十省农村7岁以下儿童体格发育调查”资料中西部五省的13 454名婴儿作为研究对象,采用SPSS13.0统计软件进行数据分析。结果:在13 454名婴儿中,男童占50.42%,女童占49.58%,不同月龄组婴儿性别分布差异无统计学意义;生长迟缓、消瘦、体重低下的检出率分别为6.58%、4.07%和3.00%;母乳喂养组、混合喂养组、人工喂养组体重低下的检出率分别为2.50%、4.19%和5.26%,生长迟缓的检出率分别为6.44%、6.50%和11.46%,消瘦的检出率分别为4.28%、3.52%和3.72%。3组婴儿体重低下及生长迟缓的检出率比较差异有统计学意义(P<0.05),而3组婴儿消瘦的检出率比较差异无统计学意义(P>0.05)。结论:西部农村婴儿4个月内采取母乳喂养者体重低下和生长迟缓的检出率较低,故应坚持母乳喂养,以减少营养不良的发生。
OBJECTIVE: To explore the correlation between feeding patterns and malnutrition within 4 months of rural infants in western China. Methods: A total of 13 454 infants from five provinces in central and western China from “2006 Physical Development Survey of Children Under 7 Years in Rural Areas of Ten Provinces of China” were selected as research object and SPSS13.0 statistical software was used for data analysis. Results: Among 13 454 infants, boys accounted for 50.42% and girls accounted for 49.58%. There was no significant difference in gender distribution among infants of different ages. The rates of growth retardation, weight loss and weight loss were 6.58%, 4.07 % And 3.00%. The detection rates of low body weight in breastfeeding group, mixed feeding group and artificial feeding group were 2.50%, 4.19% and 5.26% respectively, the detection rate of slow growth were 6.44%, 6.50% and 11.46% The detection rate of wasting were 4.28%, 3.52% and 3.72% respectively. There were significant differences in the detection rate of low birth weight and growth retardation between the three groups (P <0.05), while there was no significant difference in the detection rate of weight loss between the three groups (P> 0.05). Conclusion: The detection rate of low birth weight and slow growth rate of breastfeeding babies in western rural areas during 4 months is low, so breastfeeding should be persisted to reduce malnutrition.
