The findings on the relationship between breastfeeding and children's motor development are very poor, particularly in low and middle income countries, because of the use of inadequate measures of breastfeeding practices.
To assess the relationship between exclusive breastfeeding, measured by the deuterium-oxide turnover method (DTM), and the acquisition of motor development in a cohort of Senegalese children.
One hundred forty mother-infant (4-5 mo) pairs were recruited and monitored up to 18 mo. Breast milk intake and breastfeeding practices were measured by DTM. Six stages of motor development were assessed: "sitting without support," "hands-and-knees crawling," "standing with assistance," "walking with assistance," "standing alone," and "walking alone." Acquisition age of motor milestones between exclusively breastfed (EBF) and not exclusively breastfed (non-EBF) infants was compared using Student's and Wilcoxon's tests. Mixed linear regression, adjusted with confounding factors, was used to determine the association between EBF and motor development.
Overall, 32.9% of infants were EBF at the enrollment at 4-5 mo of age. Breast milk intake of EBF infants was significantly higher than that of non-EBF infants (1039 ± 193 g/d compared with 915 ± 211 g/d; P < 0.01). At 4-5 mo of age, only "sitting without support" (67.4% compared with 47.9%, P = 0.02) and "hands-and-knees crawling" (17.4% compared with 4.3%, P = 0.01) were completed significantly in the EBF group. At 18 mo, all children had completed all 6 motor developmental milestones. However, their acquisition age was significantly earlier in the EBF group after adjustment. Non-EBF infants had a delay of 0.4 to 0.5 mo on the acquisition of the first 5 stages compared to EBF infants. For "walking alone," no difference was found after adjustment.
Motor skill acquisition is earlier in EBF infants compared to non-EBF infants. This finding highlights the need to strengthen the advocacy for EBF up to 6 mo.
由于对母乳喂养行为的测量方法不完善，关于母乳喂养与儿童运动发育之间关系的研究结果很不理想，尤其是在低收入和中等收入国家。
采用氧化氘转换法（DTM）评估纯母乳喂养与一群塞内加尔儿童运动发育获得情况之间的关系。
招募了140对母婴（4 - 5个月），并对其进行监测直至18个月。通过DTM测量母乳摄入量和母乳喂养行为。评估了运动发育的六个阶段：“独坐”“手膝爬行”“扶站”“扶走”“独站”和“独走”。使用学生检验和威尔科克森检验比较纯母乳喂养（EBF）和非纯母乳喂养（非EBF）婴儿运动里程碑的获得年龄。采用经混杂因素调整的混合线性回归来确定EBF与运动发育之间的关联。
总体而言，32.9%的婴儿在4 - 5个月龄入组时为纯母乳喂养。纯母乳喂养婴儿的母乳摄入量显著高于非纯母乳喂养婴儿（分别为1039±193克/天和915±211克/天；P<0.01）。在4 - 5个月龄时，纯母乳喂养组仅在“独坐”（67.4%对47.9%，P = 0.02）和“手膝爬行”（17.4%对4.3%，P = 0.01）方面完成情况显著更好。在18个月时，所有儿童都完成了所有6个运动发育里程碑。然而，调整后纯母乳喂养组的获得年龄明显更早。与纯母乳喂养婴儿相比，非纯母乳喂养婴儿在前5个阶段的获得延迟了0.4至0.5个月。对于“独走”，调整后未发现差异。
与非纯母乳喂养婴儿相比，纯母乳喂养婴儿运动技能的获得更早。这一发现凸显了加强对6个月龄内纯母乳喂养宣传的必要性。
