This cluster-randomized trial evaluated the effectiveness and residual effect of an educational intervention to improve breastfeeding knowledge and attitudes among fifth grade children of both sexes in Brazil. Schools were considered clusters and analysis of variance was used to compare an intervention group (n = 298) and a control group (n = 253) regarding knowledge, perceptions, and beliefs about breastfeeding before and after the intervention, measured through a standardized 25-item, multiple-choice questionnaire. The scores in the intervention group improved significantly, with the effect lasting at least 3 months. The intervention had greater impact on girls and on students between 9 and 11 years of age when compared with boys and students between 12 and 17 years old and also between students from public schools. Results suggest that pro-breastfeeding interventions in schools improve breastfeeding knowledge and attitudes.
这项整群随机试验评估了一项教育干预措施在巴西五年级男女儿童中提高母乳喂养知识和态度方面的有效性及残留效果。学校被视为群组，采用方差分析比较干预组（n = 298）和对照组（n = 253）在干预前后关于母乳喂养的知识、认知和信念，这些通过一份标准化的25项多项选择题问卷进行测量。干预组的得分显著提高，且效果至少持续3个月。与男孩以及12至17岁的学生相比，该干预对女孩和9至11岁的学生影响更大，对公立学校的学生影响也更大。结果表明，在学校开展的支持母乳喂养干预措施可提高母乳喂养知识和态度。
