Because of the maternal diet's importance, numerous studies have examined the effects of olive oil on pregnancy outcomes. This study provides a systematic review that evaluates the evidence between olive oil consumption and maternal-fetal outcomes. We hypothesized that olive oil reduced the risk of adverse pregnancy complications. We searched Web of Science, Scopus, PubMed, and Biblioteca Virtual em Saúde electronic databases (October and November 2021). The keywords used were pregnancy, olive oil, and pregnancy outcomes. This review included all the available studies in English and Portuguese. The exclusion criteria were (1) unrelated to olive oil consumption, (2) other outcomes, and (3) animal studies. The review included 9 articles (6 experimental and 3 observational). In the maternal outcome studies (n = 6), a higher olive oil consumption was associated with a lower prevalence of gestational diabetes mellitus, preeclampsia, and cardiovascular risk. In the fetal outcome studies (n = 8), olive oil consumption was associated with a lower risk for small- or large-for-gestational-age infants. Olive oil consumption confers protective effects on pregnancy outcomes; however, further studies are needed that are specifically designed for the impact of olive oil consumption on maternal-fetal outcomes.
由于母体饮食的重要性，许多研究都探讨了橄榄油对妊娠结局的影响。本研究进行了系统评价，评估了橄榄油摄入与母婴结局之间的证据。我们假设橄榄油降低了不良妊娠并发症的风险。我们在 Web of Science、Scopus、PubMed 和 Biblioteca Virtual em Saúde 电子数据库（2021 年 10 月和 11 月）中进行了检索。使用的关键词是妊娠、橄榄油和妊娠结局。本综述纳入了所有英文和葡萄牙文的现有研究。排除标准为：（1）与橄榄油摄入无关；（2）其他结局；（3）动物研究。本综述纳入了 9 篇文章（6 项实验研究和 3 项观察性研究）。在母体结局研究（n=6）中，较高的橄榄油摄入与妊娠期糖尿病、先兆子痫和心血管风险的发生率较低相关。在胎儿结局研究（n=8）中，橄榄油摄入与较小或较大的胎儿体重儿的风险较低相关。橄榄油摄入对妊娠结局具有保护作用；然而，需要进一步进行专门针对橄榄油摄入对母婴结局影响的研究。
