[目的]分析河南省6岁以下儿童营养状况存在问题,为制定营养改善对策提供科学依据。[方法]采用横断面调查设计和分层多阶段随机抽样方法,获得1272名6岁以下儿童生长发育资料,采用WHO推荐标准,以Z值法评价儿童的身高体重发育状况以及营养状况。[结果]河南省6岁以下儿童平均身高为92.70cm(男女分别为93.34cm和91.81cm),平均体重为14.06kg(男女分别为14.43kg和13.54kg),平均头围为36.05cm(男女分别为36.95cm和36.15cm);生长迟缓、低体重、消瘦和超重/肥胖的发生率分别为6.34%、2.31%、0.91%和3.62%,均低于同期全国平均水平(分别为9.9%,5.9%,2.2%和5.4%);贫血率为17.61%。[结论]河南省6岁以下儿童的营养状况比同期全国平均水平好,但调查结果提示依然存在营养不良和贫血等问题,应有针对性地加以改善。
[Objective] To analyze the existing problems of nutritional status of children under 6 years old in Henan Province and provide scientific basis for formulating nutrition improvement measures. [Methods] Cross-sectional survey design and stratified multi-stage random sampling method were used to obtain the growth and development data of 1272 children under 6 years of age. The WHO recommended standards were used to evaluate the children’s height and weight development status and nutritional status by Z value method. [Results] The average height of children under 6 years old in Henan Province was 92.70 cm (93.34 cm and 91.81 cm respectively for men and women), the average body weight was 14.06 kg (male and female were 14.43 kg and 13.54 kg respectively), with an average head circumference of 36.05 cm (36.95 cm and 36.15 cm). The incidences of slow growth, low body weight, weight loss and overweight / obesity were 6.34%, 2.31%, 0.91% and 3.62%, respectively, lower than the national average over the same period (9.9% and 5.9% %, 2.2% and 5.4% respectively); anemia rate was 17.61%. [Conclusion] The nutritional status of children under 6 years old in Henan Province is better than the national average over the same period. However, the survey results suggest that malnutrition and anemia still exist and should be improved in a targeted manner.
