To evaluate the efficacy of counseling sessions on breast-feeding for adolescent mothers and maternal grandmothers on the reduction of unnecessary water and herbal teas intake on breast-fed infants.
A randomized clinical trial was conducted involving adolescent mothers, newborn infants, and maternal grandmothers allocated into four groups: mother and grandmother not cohabitating, without intervention; mother and grandmother not cohabitating, with intervention directed only toward mother; mother and grandmother cohabitating, without intervention; and mother and grandmother cohabitating, with intervention directed toward both. The intervention consisted of six counseling sessions on breastfeeding: in the maternity ward, and after birth on days 7, 15, 30, 60, and 120 at home. The data about feeding practices were collected by telephone every month until the end of the sixth month of the baby's life. The effect of the intervention was measured by comparing the medians and the survival curves for initiation of water and/or tea intake in the first 6 months of life, and Cox regression was used to estimate its magnitude.
The intervention had a positive effect for the group in which the adolescent mothers cohabitated with the baby's grandmother (hazard ratio = .53; 95% confidence interval = .35-.80), and also for the group in which they did not cohabitate with the baby's grandmother (hazard ratio = .48; 95% confidence interval = .31-.76). By comparing the medians of the time of initiation of water and/or tea intake between control and intervention groups, it was observed that the intervention postponed the use of these liquids in 67 days in the group in which mothers and grandmothers cohabitated and in 44 days in the group in which they did not live together.
Multiple counseling sessions on infant feeding in the first 4 months postpartum for adolescent mothers and maternal grandmothers, when they cohabitate, proved to be an effective strategy to postpone the unnecessary water and/or tea intake of breast-fed infants.
评估针对青少年母亲和产妇祖母的母乳喂养咨询对减少母乳喂养婴儿摄入不必要的水和草药茶的效果。
进行了一项随机临床试验，涉及青少年母亲、新生儿和产妇祖母，将其分为四组：不共同居住、无干预的母亲和祖母；不共同居住、仅对母亲进行干预的母亲和祖母；共同居住、无干预的母亲和祖母；以及共同居住、对双方均进行干预的母亲和祖母。干预措施包括六次母乳喂养咨询：在产科病房，以及产后第 7、15、30、60 和 120 天在家中进行。每月通过电话收集有关喂养实践的数据，直到婴儿生命的第六个月结束。通过比较前 6 个月开始摄入水和/或茶的中位数和生存曲线来衡量干预的效果，并使用 Cox 回归估计其幅度。
对于青少年母亲与婴儿祖母共同居住的组（风险比=0.53；95%置信区间=0.35-0.80）和不与婴儿祖母共同居住的组（风险比=0.48；95%置信区间=0.31-0.76），干预具有积极效果。通过比较对照组和干预组开始摄入水和/或茶的中位数，可以观察到干预使共同居住的母亲和祖母组推迟了 67 天使用这些液体，而不共同居住的组则推迟了 44 天。
对于共同居住的青少年母亲和产妇祖母，在产后前 4 个月内进行多次关于婴儿喂养的咨询，被证明是推迟母乳喂养婴儿摄入不必要的水和/或茶的有效策略。
