| 目的探索中国西部农村地区婴幼儿营养、喂养以及保健方面的性别差异。方法利用西部农村大样本横断面调查数据，共调查14532名儿童；运用Iogistic回归模型控制有关背景因素来估计性别在3岁以下农村儿童的营养、喂养和保健方面所起的作用。结果西部南北方地区男女儿童的生长迟缓、低体重和消瘦患病率接近，但是控制了可能的影响因素后，营养不良的性别差异只出现在北方儿童中，表现为北方l孩家庭的男童低体重的风险要高于女童(OR=1．27)，3孩以上家庭的男童患生长迟缓的风险却低于女童(O尺=0．60)；在南方地区无论是在1孩还是多孩家庭以上三指标均没有显著的性别差异。北方地区只表现为2孩家庭的男童添加鸡蛋的频率要显著高于女童，而此种情况也出现在南方1孩家庭中；此外，南方地区表现为2孩家庭的女童在4月龄内比男童更倾向于接受纯母乳喂养。在保健方面，男童较女童更容易患病，贫血患病率分别为36．2％和33．4％，2周感冒和腹泻患病率分别为29．0％和27．4％，19．0％和17．5％。结论中国西部农村婴幼儿在营养、喂养和保健方面存在着一定的性别差异，北方地区比南方地区表现突出。 |

| Objective To investigate sex difference on nutritional status,feeding practice and healthcare of rural children in western China. Methods Data used in this study was from a large scale cross-sectional survey conducted in western rural areas of China. The total number of children younger than 3years old was 14 532, in which 57.4% were boys. Logistic regression model was employed to controlselected background factors for analysis of sex differential on nutritional status, feeding practice and healthcare of children. Results The prevalence rates of stunting, underweight and wasting were close betweenboth genders, regardless of north or south areas. After controlling of selected background factors, sexdifferentials in malnutrition happened only in north areas. It showed that boys having higher risk of beingunderweight than girls ( OR=1.27) in the families with one child and lower risk of being stunting thangirls(OR=0.60). There was no sex differential found in stunting*underweight and wasting for any typeof families in south areas. As for feeding practice egg was introduced to boys more frequently compared withgirls,which was found in families with one child of south areas and ones with two children from thesouthern areas. More boys from families with two children of southern areas were exclusively breastfedwithin 4 months after birth. Data indicated boys had higher risk of being sick. prevalence of anemia was36. 2 % for boys, 33. 4 % for girls. Prevalence of cold was 29. 0 % for boys, 27.4 0,6 for girls. prevalence ofdiarrhea was 19.0 % for boys,17.5 % for girls. This sex differential persisted in the families of north areasafter controlling for selected background factors. Conclusion Sex differentials on nutritional status,feedingpractice and health care exist in rural areas of western China,especially in north areas. |
