地震灾区宁强县6～24月龄婴幼儿营养干预周期研究
|
摘要
【目的】探讨宁强县6～24月龄婴幼儿营养干预效果与干预周期的关系。【方法】按照干预措施实施的时限将婴幼儿分组,分别比较不同时限干预组与未干预组婴幼儿的年龄别体重Z评分(Weight-for-age Z-score,WAZ)、年龄别身长Z评分(Height-for-age Z-score,HAZ)、身高别体重Z评分(Weight-for-Height Z-score,WHZ)以及血红蛋白的差异。【结果】干预0～2.9月组、3～5.9月组和6～8.9月组的WAZ分别为0.37±1.25、0.07±0.97、0.07±1.02,与未干预组相比差异存在统计学意义(P<0.01);干预0～2.9月组、3～5.9月组和6～8.9月组的WHZ分别为0.55±1.11、0.43±1.00、0.32±1.26,较未干预组有显著增加(P<0.01);干预0～2.9月组(P<0.01)、6～8.9月组(P<0.05)的HAZ较未干预组显著增加。【结论】通过营养干预可以显著改善宁强县6～24月龄婴幼儿营养状况,本研究存在"0～9个月"的敏感干预周期。
【Objective】 To investigate the relationship between effectiveness and periods of nutrition interventions about infants aged 6~24 months in Ningqiang county.【Methods】 Infants were divided according to periods of nutrition interventions.And the differences of infants' weight-for-age Z-score(WAZ),height-for-age Z-score(HAZ),weight-for-height Z-score(WHZ)and hemoglobin concentration between groups were compared.【Results】 The WAZ of 0~2.9 months group,3~5.9 months group and 6~8.9 months group were 0.37±1.25,0.07±0.97,0.07±1.02,respectively,and they increased significantly compared to the baseline(P<0.01).The WHZ of 0~2.9 months group,3~5.9 months group and 6~8.9 months group were 0.55±1.11,0.43±1.00,0.32±1.26,respectively,there were significant differences between intervention groups and non-intervention group.(P<0.01).The HAZ of 0~2.9 months group(P<0.01)and 6~8.9 months group(P<0.05) also increased significantly.【Conclusions】 Through nutrition interventions the nutrition status of infants aged 6~24 months could be improved significantly.And there is a susceptive periods of nutrition interventions '0~9months'.
