To describe the duration of breast-feeding between 1990 and 2013 and to estimate the association between breast-feeding duration and sociodemographic, health and pro-breast-feeding policies and programmes in Latin American countries.
This is a cross-sectional study with data from Demographic and Health Surveys programme conducted in Bolivia, Brazil, Colombia, Peru and the Dominican Republic between 1990 and 2013. The median duration of breast-feeding was estimated by survival analysis. Information on pro-breast-feeding policies and programmes was extracted from the World on Breastfeeding Trends Initiative (WBTi) tool. The association between the duration of breast-feeding and WBTi tool score was analysed by multilevel survival regression.
Nationally representative cross-sectional survey from Bolivia, Brazil, Colombia, Peru and Dominican Republic.
We included children under 24 months of age, totalling 17 318 children.
Breast-feeding duration showed a significant increase in all countries, except the Dominican Republic. Mothers with higher schooling level (HR = 1·66; 95 % CI 1·35, 2·04), higher income (HR = 1·58; 95 % CI 1·40, 1·77) and overweight (HR = 1·14; 95 % CI 1·05, 1·23) breastfed for a shorter time. Breast-feeding in the first hour of life (HR = 0·79; 95 % CI 0·74, 0·83) was associated with increase in the duration of breast-feeding. Regarding WBTi, Peru presented the lowest score and the Dominican Republic presented the highest score. WBTi score was inversely related to the duration of breast-feeding for this set of countries (HR = 1·07; 95 % CI 1·02, 1·12).
Mothers with better socio-economic conditions and overweight breastfed for a shorter time. Breast-feeding in the first hour was associated with longer duration of breast-feeding. In this set of countries, higher scores from WBTi tool did not result in longer duration of breast-feeding.
描述 1990 年至 2013 年期间的母乳喂养持续时间,并评估母乳喂养持续时间与社会人口统计学、健康状况和促进母乳喂养政策及方案之间的关系,对象为拉丁美洲国家。
这是一项使用来自 1990 年至 2013 年期间在玻利维亚、巴西、哥伦比亚、秘鲁和多米尼加共和国开展的人口与健康调查项目数据的横断面研究。采用生存分析估计母乳喂养的中位数持续时间。从世界母乳喂养趋势倡议(WBTi)工具中提取促进母乳喂养政策及方案的信息。采用多级生存回归分析母乳喂养持续时间与 WBTi 工具评分之间的关联。
来自玻利维亚、巴西、哥伦比亚、秘鲁和多米尼加共和国的具有全国代表性的横断面调查。
纳入了年龄在 24 个月以下的儿童,共 17318 名儿童。
除多米尼加共和国外,所有国家的母乳喂养持续时间均呈显著增加趋势。文化程度较高(HR=1.66;95%CI 1.35,2.04)、收入较高(HR=1.58;95%CI 1.40,1.77)和超重(HR=1.14;95%CI 1.05,1.23)的母亲母乳喂养时间较短。生命最初 1 小时内进行母乳喂养(HR=0.79;95%CI 0.74,0.83)与母乳喂养持续时间的延长相关。就 WBTi 而言,秘鲁的得分最低,多米尼加共和国的得分最高。对于这组国家,WBTi 评分与母乳喂养持续时间呈反比(HR=1.07;95%CI 1.02,1.12)。
社会经济条件较好和超重的母亲母乳喂养时间较短。生命最初 1 小时内进行母乳喂养与母乳喂养持续时间较长相关。在这组国家中,WBTi 工具的较高得分并未导致母乳喂养持续时间延长。
