It has been known for decades that breastfeeding leads to a lower risk of asthma, respiratory infections, or metabolic syndrome at school age. In addition, evidence is now accumulating on the influence of breast milk on the shape, volume, or function of the heart and lungs. Within this field of research into the effects of breast milk on the structure of the heart and lungs, we have set out to analyze the differential electrocardiographic characteristics of schoolchildren who were once breastfed.
This was an observational cross-sectional study, including 138 children aged 6 or 12 consecutively presenting to a well-child clinic between May and December 2022.
The ability to perform reproducible ECG records, the feasibility of weighing and measuring patient, and breastfeeding data collected from birth were used as the inclusion criteria.
Using the 40° cut-off value for the mean P-wave axis among schoolchildren, 76% of never-breastfed children in our sample have a P-wave axis in a more vertical position than the mean as compared to 58% of ever-breastfed children (OR: 2.25; 95% CI: 3.13-1.36); there was no other significant difference between infant feeding groups in somatometric characteristics or ECG parameters.
We found a significant difference of the mean values of the P-wave axis between never- and ever-breastfed children. Although this report should be approached cautiously, these findings add to the renewed interest in discerning developmental interventions to improve cardiovascular health.
几十年来，人们已经知道母乳喂养会降低学龄期患哮喘、呼吸道感染或代谢综合征的风险。此外，关于母乳对心肺形状、体积或功能影响的证据正在不断积累。在这个研究母乳对心肺结构影响的领域中，我们着手分析曾经接受母乳喂养的学龄儿童的心电图差异特征。
这是一项观察性横断面研究，纳入了2022年5月至12月期间连续到一家儿童健康诊所就诊的138名6岁或12岁儿童。
能够进行可重复的心电图记录、对患者进行称重和测量的可行性以及从出生时收集的母乳喂养数据被用作纳入标准。
在学龄儿童中，使用平均P波轴40°的临界值，我们样本中76%从未接受母乳喂养的儿童的P波轴位置比平均值更垂直，而曾经接受母乳喂养的儿童这一比例为58%（比值比：2.25；95%置信区间：3.13 - 1.36）；婴儿喂养组在人体测量特征或心电图参数方面没有其他显著差异。
我们发现从未接受母乳喂养和曾经接受母乳喂养的儿童之间P波轴平均值存在显著差异。尽管对本报告应谨慎看待，但这些发现增加了人们对识别改善心血管健康的发育干预措施的新兴趣。
