To study association of semen quality with a priori whole dietary pattern indexes, which reflect real-world dietary practices and the numerous combinations by which foods are consumed: Healthy Eating Index (HEI), Dietary Approaches to Stop Hypertension (DASH), alternate Mediterranean Diet score (aMED), and Alternative Healthy Eating Index (AHEI).
A cross-sectional single-center study.
Hospital fertility center and university.
PATIENT(S): A total of 280 men attending fertility center from 2012 to 2015.
INTERVENTION(S): Food frequency questionnaire (FFQ) and semen and sperm analysis.
MAIN OUTCOME MEASURE(S): Food consumption with the use of FFQ and HEI, AHEI, aMED, DASH nutritional individual scoring indexes. Semen parameters, including semen volume, sperm concentration, motility, total count, and morphology.
RESULT(S): Comparing the highest and lowest quartiles of the nutritional indexes, men in the highest quartiles of HEI, AHEI, aMed, and DASH indexes had significantly higher adjusted means of sperm concentration (by 10%, 45%, and 24% for HEI, AHEI, and DASH, respectively), normal sperm morphology (by 21% and 8% for AHEI and DASH, respectively), total sperm count (by 29% for AHEI), and sperm motility (by 6% and 11% for aMed and HEI, respectively).
CONCLUSION(S): Adherence to any of the four dietary indexes is associated with better overall sperm quality, with AHEI best associated. Following our novel findings, we recommend using AHEI as a clinical and practical tool for public whole nutritional recommendation for semen quality.
研究精液质量与预先设定的整体饮食模式指数之间的关联，这些指数反映了真实世界的饮食实践以及食物摄入的众多组合方式：健康饮食指数（HEI）、停止高血压的饮食方法（DASH）、替代地中海饮食评分（aMED）和替代健康饮食指数（AHEI）。
一项横断面单中心研究。
医院生育中心和大学。
2012 年至 2015 年期间，共有 280 名男性到生育中心就诊。
使用食物频率问卷（FFQ）和精液及精子分析。
使用 FFQ 和 HEI、AHEI、aMED、DASH 营养个体评分指数评估食物摄入情况。精液参数，包括精液量、精子浓度、活力、总数和形态。
比较营养指数的最高和最低四分位数，HEI、AHEI、aMed 和 DASH 指数最高四分位数的男性精子浓度调整平均值显著较高（HEI、AHEI 和 DASH 分别增加 10%、45%和 24%），正常精子形态（AHEI 和 DASH 分别增加 21%和 8%），总精子数（AHEI 增加 29%）和精子活力（aMed 和 HEI 分别增加 6%和 11%）。
四种饮食指数中的任何一种都与整体精子质量相关，其中 AHEI 相关性最佳。基于我们的新发现，我们建议将 AHEI 作为一种临床和实用工具，用于公众整体营养推荐以改善精子质量。
