Abstract: Objective To analyze the nutritional status of children in poor areas of Yunnan,and to explore the correlation among dietary scores (DDS) and the index of growth and development.Methods Participants of 2006-2009 nutritional surveillance project from four poor counties of Yunnan were included.Indexes,such as DDS9,the-height-for-age Z score (HAZ),the-weight-for-age Z score (WAZ),the-weight-for- height Z score (WHZ) and the prevalence of malnutrition were constructed using the database.Then the correlation of these indexes was analyzed. Results A total of 1 686 children were included in this study.The prevalence of underweight,stunting and wasting among these children were 24.3%,24.7% and 7.5% respectively.Average DDS9 was 6.0±1.38,which was positively associated with HAZ (r=0.11,P=0.00)and WAZ(r=0.063,P=0.01).However,the same association was not found with WHZ(r=-0.02,P=0.327).Binary Logistic regression suggested the lacking of milk、meat and aquatic food consumption were risk factors for malnutrition.Conclusion Preschool children in poor areas of Yunnan faced the lacking of food diversity and many of them suffered from malnutrition.DDS9 is correlated with some growth indexes,and could be applied in the work of nutrition improvement.

摘要: 目的 分析云南贫困地区儿童营养状况,探索膳食多样化评分(dietary diversity score,DDS)与生长发育指标的相关性。方法 计算2006-2009年云南省4个贫困县儿童营养监测项目中膳食调查对象最近24 h内9类食物的膳食多样化评分(DDS9),同时计算其年龄别身高、年龄别体重和身高别体重Z评分(HAZ、WAZ、WHZ)及营养不良率,分析食物消费状况和生长发育指标的相关性。结果 共1 686名2~6岁儿童进入分析。儿童低体重率、生长迟缓率和消瘦率分别为24.3%、24.7%和7.5%。DDS9平均为6.0±1.38,DDS9与HAZ及WAZ呈显著性正相关(r=0.11,P=0.00;r=0.063,P=0.01),而与WHZ未见显著性相关(r=-0.02,P=0.327)。各类食物消费与生长发育指标的单因素Logistic回归分析显示:缺乏乳类、肉类和水产品消费分别为生长迟缓、低体重和消瘦的危险因素。结论 云南贫困地区2~6岁儿童膳食多样化程度低,营养不良率高。DDS9与儿童生长发育指标呈一定相关性,在儿童膳食质量评价、营养不良预测方面有一定的应用价值。
