目的研究成都地区母乳喂养持续时间及其影响因素。方法采用分层整群随机抽样法选取成都地区城乡1178名6～24月龄婴幼儿作为研究对象,通过问卷调查收集婴幼儿及家庭基本情况和母乳喂养相关信息,运用Kaplan-Meier法和Cox比例风险模型分析母乳喂养持续时间及其影响因素。结果调查对象母乳喂养持续时间(P50)分别为城市6.0个月(P25～P75:3～8.5个月)和农村8.0个月(P25～P75:5～11个月),城乡差异有显著性(P<0.05);婴幼儿饮食月消费与母乳喂养持续时间呈负相关(城乡RR值分别为0.163和0.312),母亲产假与母乳喂养持续时间呈正相关(城乡RR值分别为1.508和2.191)。结论成都地区母乳喂养时间普遍不足,需采取针对性的干预措施给予改善。
Abstract：Objective To investigate the status and relevant factors influencing the duration of breastfeeding in urban and rural areas of Chengdu,China.Methods 1178 infants and young children aged 6-24 months were selected by stratified cluster random sampling.Breastfeeding information for subjects was obtained by interviewing mothers with a questionnaire.Kaplan-Meier method and Cox proportional hazard model were used to identify the factors associated with the termination of breastfeeding.Results The median of the duration for breastfeeding was 6.0 months in the urban group and 8.0 months in the rural group(P<0.05).This study showed that the cost of food consumed by baby was negatively correlated with breastfeeding duration,but the maternity leave was positively correlated with breastfeeding duration.Conclusion Breastfeeding duration for children in Chengdu was insufficient.Intervention program should be implemented to improve breastfeeding status.
