在怀孕期间遵守DASH和HEI等特定饮食可能会降低不充分的妊娠体重增加 (GWG) 的风险. 这项研究没有发现这些饮食与过度GWG之间的联系.
科学领域:
- 产科和妇科
- 营养科学
- 公共卫生
背景情况:
- 不理想的妊娠体重增加 (GWG) 与母亲的不良结果有关.
- 关于怀孕期间特定饮食模式对GWG的影响的证据有限.
- 这项研究调查了五种饮食模式与GWG类别之间的关联.
研究的目的:
- 评估遵守行星健康饮食 (PHD),阻止高血压的饮食方法 (DASH),替代地中海饮食 (AMED),健康饮食指数 (HEI) 和替代健康饮食指数 (AHEI) 和GWG之间的关系.
- 确定遵守这些饮食是否会影响GWG不足或过多的几率.
主要方法:
- 使用来自NICHD胎儿成长研究的数据,包括早孕妇女的食物频率问卷.
- 计算了PHD,DASH,AMED,HEI和AHEI的坚持得分.
- 使用多项逻辑回归来分析高与低依从性和GWG类别 (不充分,充分,过度) 之间的关联.
主要成果:
- 与较低的坚持相比,对DASH,AMED,HEI或AHEI的高度坚持与总GWG不足的概率降低了13%至31%.
- 对DASH和HEI的高度坚持表明,第一季度GWG不足的几率显著降低.
- 没有发现任何饮食模式的坚持和过度的总体或季度特异性GWG之间有显著的关联.
结论:
- 更多地坚持DASH,AMED,HEI和AHEI饮食模式与GWG不足的几率降低有关.
- 未来的研究应该使用代谢物特征来探索客观的饮食特征,以了解GWG的关联.
