Abstract:
Objective: To describe the situation and identify factors associated with malnutrition among infants and young children aged 6-23 months in poor rural areas in Hunan Province in 2015. Methods: 8 735 rural infants and young children aged 6-23 months in 30 poor counties of Wuling Mountains and Luoxiao Mountains in Hu'nan province were selected by township-level probability proportional to size sampling (PPS) in August 2015, infants' body length and weight were measured, and questionnaires were used to collect infants' information on personal and family, and feeding status in the past 24 h. The prevalence of stunting, underweight and wasting were calculated according to the Growth Standards of Child Aged Under 7 in China which was established in 2009 by Community Health Department of National Health and Family Planning Commission, China (formerly Chinese MOH), and the prevalence of malnutrition was calculated according to the classification of children with anthropometric failure. Multi non-conditional logistic regression model were used to analyze factors associated with malnutrition among infants and young children aged 6-23 months. Results: The prevalence of malnutrition among infants and young children aged 6-23 months was 13.7% (1 198/8 735), the prevalence of stunting, underweight and wasting among infants and young children aged 6-23 months were 4.8% (419/8 735), 9.7% (849/8 735) and 6.1% (531/8 735) respectively. Compared with male group, the OR value of malnutrition for the female group was 1.16; Compared with Han ethnic group, the OR value of malnutrition for the Miao and Tujia ethnic group were 0.83 and 0.66, respectively; Compared with mother with an education level of primary school or below, the OR value of malnutrition for the mother with junior high school, senior high school and university or above education were 0.65, 0.61 and 0.56, respectively; Compared with father with an education level of primary school or below, the OR value of malnutrition for the father with senior high school and university or above education were 0.71 and 0.61 respectively; Compared with normal birth weight group, the OR value of malnutrition for the low birth weight group and high birth weight group were 2.85 and 0.27 respectively; Compared with normal delivery group, the OR value of malnutrition for the premature delivery group was 1.37; all P values<0.05. Conclusion: The prevalence of malnutrition among infants and young children aged 6-23 months in poor rural areas in Hunan province in 2015 was high; Infants and young children who were female, Han ethnic, parents with low education, low birth weight and premature delivery had higher risk of malnutrition. 目的： 研究2015年湖南省贫困农村地区6~23月龄婴幼儿营养不良现状及其相关因素。 方法： 2015年8月在湖南省辖区内武陵山区和罗霄山区30个贫困县按乡级概率规模抽样（PPS）方法抽取8 735名农村6~23月龄婴幼儿作为研究对象，测量身长和体重，采用问卷调查个人、家庭情况以及过去24 h喂养情况等，按2009年中华人民共和国国家卫生和计划生育委员会（原卫生部）妇社司发布的《中国7岁以下儿童生长发育参照标准》计算婴幼儿生长迟缓率、低体重率和消瘦率，按儿童营养不良分类方法计算婴幼儿总的营养不良率，采用多因素非条件logistic回归模型分析婴幼儿营养不良的相关因素。 结果： 6~23月龄婴幼儿营养不良率为13.7%（1 198/8 735），生长迟缓率、低体重率和消瘦率分别为4.8%（419/8 735）、9.7%（849/8 735）和6.1%（531/8 735）。相对于男性，女性婴幼儿营养不良的OR值为1.16；相对于汉族，苗族和土家族婴幼儿营养不良的OR值分别为0.83和0.66；相对于母亲学历小学及以下，母亲初中、高中、大学及以上学历婴幼儿营养不良的OR值分别为0.65、0.61和0.56；相对于父亲学历小学及以下，父亲高中、大学及以上学历婴幼儿营养不良的OR值分别为0.71和0.61；相对于出生体重正常，低出生体重婴幼儿营养不良的OR值为2.85，出生超重婴幼儿营养不良的OR值为0.27；相对于正常月龄分娩，早产婴幼儿营养不良的OR值为1.37；P值均<0.05。 结论： 2015年湖南省贫困农村地区婴幼儿营养不良率较高；女性、汉族、父母学历低、低出生体重、早产婴幼儿是营养不良的高危人群。.
