过早分娩增加了婴儿超重和发育不良的风险,而纯母乳养可以防止营养不良. 避免非医疗指示的早期分娩,并为婴儿健康促进纯母乳养.
科学领域:
- 儿童营养和生长的增长.
- 孕产妇和胎儿的医学
背景情况:
- 关于妊娠年龄 (GA) 和母乳养对孕期婴儿生长的影响的研究有限.
- 了解这些因素对于优化婴儿健康结果至关重要.
研究的目的:
- 调查妊娠年龄和婴儿养实践与产后婴儿生长和营养状况之间的关联.
- 识别与早产和非专属母乳养相关的风险.
主要方法:
- 一个多中心的横截面研究7270个单胎婴儿在中国.
- 收集的数据包括妊娠年龄,养习惯,人体测量 (长度,体重) 和营养状况指标.
- 统计分析采用线性和逻辑回归模型,对正常出生体重的婴儿进行敏感性分析.
主要成果:
- 过早分娩与更高的体重对长度Z分数 (WLZ) 和超重/肥胖风险增加有关.
- 过早分娩也与较低的长度对年龄Z分数 (LAZ) 和在6个月之前衰老的风险更高相关.
- 与独家母乳养相比,独家配方养和混合养与较低的WLZ和中度和严重急性营养不良 (MSAM) 风险增加有关.
结论:
- 过早分娩对健康构成重大风险,包括超重和发育迟缓,在期婴儿.
- 在6个月之前的纯母乳养显示出对营养不良的保护作用.
- 建议包括避免在39周之前进行非医疗指示的分娩,并促进纯母乳养.
