延边地区6～23月龄婴幼儿的生长发育与营养状况研究

Study on growth and nutrition of infants aged from 6 to 23 months in Yanbian area

[目的]调查延边地区6~23月龄婴幼儿的生长发育与营养状况.[方法]采用分层整群抽样方法抽取延边地区842名婴幼儿作为调查对象,测量身高、体质量和血红蛋白值并进行分析.[结果]延边地区6~11,12~17和18~23月龄婴幼儿的年龄别身长(HAZ)值分别为0.44±0.06,0.16±0.06和-0.14±0.07,生长迟缓率分别为1.7%,3.6%和6.5%,不同月龄HAZ值和生长迟缓率间差异均有统计学意义(P<0.01);年龄别体质量值分别为0.50±0.06,0.22±0.06和0.32±0.03,不同月龄间差异均有统计学意义(P<0.01).延边地区6~11,12~17和18~23月龄男婴幼儿贫血率分别为20.2%,19.7%和9.0%,总贫血率分别为19.9%,17.9%和10.5%,不同月龄间差异均有统计学意义(P<0.01).[结论]延边地区6~23月龄婴幼儿生长发育与营养状况较优.

OBJECTIVE To investigate the growth and nutritional status of infants aged from 6 to 23 months in Yanbian area. METHODS A total of 842 infants in Yanbian area were selected by hierarchical cluster sampling method, and height, weight and hemoglobin value were measured and analyzed. RESULTS The value of HAZ was 0.44±0.06, 0.16±0.06 and-0.14±0.07 in the infants aged 6-11, 12-17 and 18-23 months, and the stunting prevalence was 1.7%, 3.6% and 6.5%, respectively, and the differences in HAZ values and the stunting prevalence at different months were statistically significant(P<0.01). The value of WAZ was 0.50±0.06, 0.22±0.06 and 0.32±0.03, and there was significantly different between different ages(P<0.01). The anemia prevalence of male infants aged 6-11, 12-17 and 18-23 months was 20.2%, 19.7% and 9.0%, while that in all infants was 19.9%, 17.9% and 10.5%, respectively, and the differences were statistically significant between different ages(P<0.01). CONCLUSION Growth and nutritional status of infants aged from 6 to 23 months were better in Yanbian area.
