目的 了解安徽省贫困地区儿童母乳喂养持续时间现状及其影响因素,为母乳喂养的科学干预提供依据。方法 利用国家贫困地区儿童营养改善项目调查数据资料,选取安徽省1 332名6~24个月龄儿童作为研究对象,采用Kaplan-Meier法对母乳喂养持续时间进行生存曲线估计,用Cox回归模型分析其影响因素。结果 儿童母乳喂养中位时间为10个月;Cox回归模型分析显示:母亲看护、母亲年龄、纯母乳喂养≥4个月和使用过奶瓶是母乳喂养持续时间的影响因素。结论 安徽省贫困地区儿童母乳喂养持续时间与WHO的建议有较大差距,应在贫困地区采取有效措施改善儿童母乳喂养状况。

Objective To understand the current status and influencing factors of breastfeeding in poor areas of Anhui. Methods Children aged 6 to 24 months were selected as subjects from the program on "Nutritional improvement for children in poor urban areas of China".Kaplan-Meier method was used to estimate the survival curves and Cox multivariate step-wise regression was used to identify the relevant factors on the duration of breastfeeding. Results Median of the duration for breastfeeding was 10 months in poor areas of Anhui.Cox maltivariate step-wise regression showed that factors including mother care,mother's age,exclusive breastfeeding for 4 months or more and using bottle-feeding were correlated with the duration of breastfeeding. Conclusions Duration of breastfeeding for children in poor areas of Anhui is shorter compared with WHO standard.Intervention program should be implemented to improve the current status on breastfeeding in poor areas.
