ABSTRACT

This was a cross-sectional study that aimed to evaluate the association between breastfeeding and motor development of infants at 3–4 months of age in the city of Pelotas, Rio Grande do Sul. The outcome, infant motor development, was evaluated through the Bayley Scale of Infant Development (Bayley III). The prevalence of infants that stopped breastfeeding before reaching 3–4 months of age was 16.6%. The most prevalent reason for early weaning was ‘insufficient milk flow’ (50.4%). The general mean of motor development was 104.9 (±13.2) points, and the lowest means were attributed to babies who never breastfed (101.5; SD ±14.6), followed by those stopped breastfeeding (102.5; SD ±14.1). The results revealed that infants who never breastfed and those who had stopped at 3–4 months of age presented −1.9 (CI 95% −3.8;−0.2) points in the motor development scale means when compared with infants who were still breastfeeding.

摘要

这是一项横断面研究，旨在评估南里奥格兰德州佩洛塔斯市 3-4 个月大婴儿的母乳喂养与运动发育之间的关系。结果，即婴儿运动发育，通过贝利婴儿发育量表 (Bayley III) 进行评估。在 3-4 个月大之前停止母乳喂养的婴儿的患病率为 16.6%。提早断奶最普遍的原因是“乳汁流量不足”(50.4%)。运动发育的一般平均值为 104.9 (±13.2) 分，最低平均值归因于从未母乳喂养的婴儿 (101.5; SD ±14.6)，其次是停止母乳喂养的婴儿 (102.5; SD ±14.1)。结果显示，从未母乳喂养的婴儿和在 3-4 个月大时停止母乳喂养的婴儿呈现 -1.9 (CI 95% -3.8;-0.
