目的 分析宝鸡地区母乳喂养持续时间与学龄前儿童超重和肥胖的关系,为预防宝鸡地区儿童超重和肥胖提供科学依据。方法 以2015年8月-2016年12月在宝鸡市妇幼保健院进行预防接种的3 586名3~6岁学龄前儿童作为研究对象。采用问卷调查获得学龄前儿童的母乳喂养情况,测量学龄前儿童的身高和体重,了解学龄前儿童的体格发育情况。通过Logistic回归分析计算母乳喂养持续时间与学龄前儿童超重和肥胖患病风险的OR值和95%的可信区间(CI)。结果 超重和肥胖患病率分别为12.5%和9.8%,母乳喂养持续时间与学龄前儿童超重和肥胖的患病风险呈负相关,母乳喂养≥12个月的学龄前儿童超重和肥胖的患病风险是未经母乳喂养的学龄前儿童的0.58倍。结论 较长时间的母乳喂养是学龄前儿童超重和肥胖的保护因素,应提倡长时间的母乳喂养,预防学龄前儿童超重和肥胖的发生。
Abstract
Objective To analyze the association between breastfeeding duration and the risk of overweight and obesity among preschool children,and to provide guidelines for the prevention of children's overweight and obesity. Methods A total of 3 586 preschool children aged 3~6 years who were vaccinated in the Baoji Maternal and Child Health Care Hospital from August 2015 to December 2016 were included in this study.The data of breastfeeding were obtained by questionnaires.Height and weight were measured.Logistic analysis was performed to evaluate Odds ratio (OR) and 95% Confidence interval (CI) of the risk of overweight and obesity. Results The prevalence of overweight and obesity among the participants were 12.5% and 9.8%,respectively.Breastfeeding duration was negatively associated with the risk of overweight and obesity among preschool children.The risk of overweight and obesity in preschool children who were breastfed not less than 12 months was 0.58 times that of preschool children without breastfeeding. Conclusion Longer duration of breastfeeding may be a protective factor for preventing overweight and obesity in preschool children,indicating that long-term breastfeeding should be promoted.
