Childhood is a window of opportunity for the prevention of the obesity pandemic. Since "the first 1000 days of life" is a period in which healthy eating habits must be acquired, it should be the target for preventive strategies. Baby-led weaning (BLW) is an emergent way of weaning that could influence children's health. The nutrition committees of the main pediatric societies affirm there is not enough evidence to support which is the best method of weaning. The aim was to determinate the influence of BLW on the infant's weight gain compared to the traditional spoon-feeding, and to assess if it could decrease the risk of obesity in children. A systematic review was conducted, following the PRISMA method. Pubmed, Web of Science, Embase, and Cochrane Library were searched. Out of 747 articles, eight studies (2875 total infants) were included (two randomized control trials, 6 observational studies). Results were indecisive, while some studies seem to demonstrate lower weight gain in infants that apply BLW, others show inconclusive results. The risk of bias in all included studies was moderate or high. In conclusion, more clinical trials and prospective studies should be done prior to providing a general recommendation about the best method of weaning to reduce the risk of obesity.
儿童时期是预防肥胖流行的机会窗口。由于“生命最初的 1000 天”是必须养成健康饮食习惯的时期，因此应将其作为预防策略的目标。婴儿主导的断奶（BLW）是一种新兴的断奶方式，可能会影响儿童的健康。主要儿科协会的营养委员会肯定没有足够的证据支持哪种断奶方法是最好的。目的是确定 BLW 对婴儿体重增加的影响与传统的勺喂相比，以及评估它是否可以降低儿童肥胖的风险。按照 PRISMA 方法进行了系统评价。检索了 PubMed、Web of Science、Embase 和 Cochrane Library。在 747 篇文章中，纳入了八项研究（共 2875 名婴儿）（两项随机对照试验，6 项观察性研究）。结果不确定，一些研究似乎表明采用 BLW 的婴儿体重增加较低，而其他研究则得出不确定的结果。所有纳入研究的偏倚风险均为中度或高度。总之，应该进行更多的临床试验和前瞻性研究，然后才能就减少肥胖风险的最佳断奶方法提供一般性建议。
