Abstract

This systematic review and meta-analysis aimed to evaluate the association between adherence to a healthy dietary pattern and outcomes of assisted reproductive techniques (ARTs). PubMed, Embase and Web of Science were searched for eligible studies through December 2019 according to the population, intervention, comparison, outcome and study design (PICOS) criteria. Eight prospective cohort studies (S) reporting pregnancy outcomes (O) of higher vs lower adherence to a healthy dietary pattern (I/C) in women undergoing ART treatment (P) were included, involving a total of 2229 women with 2067 embryo transfer cycles. The pooled odds ratio (OR) for positive pregnancy test, clinical pregnancy and ongoing pregnancy/live birth was 0.82 (95% confidence interval [CI] 0.65–1.03), 0.99 (95% CI 0.68–1.44) and 1.30 (95% CI 0.81–2.09), respectively. In conclusion, greater adherence to a healthy dietary pattern rich in vegetables, fruits, whole grains, legumes and fish, may not be significantly related to ART success.

摘要

这项系统评价和荟萃分析旨在评估坚持健康饮食模式与辅助生殖技术 (ARTs) 结果之间的关联。根据人群、干预、比较、结果和研究设计 (PICOS) 标准，在 PubMed、Embase 和 Web of Science 中搜索了截至 2019 年 12 月的合格研究。八个前瞻性队列研究（S）报告的更高的妊娠结局（O）VS接受 ART 治疗 (P) 的女性对健康饮食模式 (I/C) 的依从性较低，共涉及 2229 名具有 2067 个胚胎移植周期的女性。阳性妊娠试验、临床妊娠和持续妊娠/活产的汇总优势比 (OR) 为 0.82（95% 置信区间 [CI] 0.65–1.03）、0.99（95% CI 0.68–1.44）和 1.30（95% CI） 0.81–2.09)，分别。总之，更多地坚持富含蔬菜、水果、全谷物、豆类和鱼类的健康饮食模式，可能与 ART 的成功没有显着关系。
