Objective: The systematic review with meta-analysis aimed to verify the occurrence of a protective effect on hearing loss due to a higher intake of carotenoids, vitamins A, C, E, and folate present in diets. Methods: The search for scientific articles was carried out by 2 independent researchers in electronic databases. Meta-analysis was performed by constructing summary risk measures for each vitamin or antioxidant, combining the risk ratios or adjusted odds ratios (OR) for the various variables observed in the highest categories of vitamin or antioxidant consumption. Results: Five studies involving an estimated 100 549 participants were included in the quantitative synthesis. The summary measures calculated for the highest quartiles/quintiles of the studies were Hazard ratios (HR) .990 for vitamin C; HR 1.07 and OR .925 for vitamin E; HR .921 for folate and OR .906 for vitamin A. Conclusion: Dietary intake of vitamins and antioxidants was inversely associated with the risk of developing hearing loss. Individuals with a higher intake of antioxidants may have better hearing thresholds, especially with the intake of β-carotene.
目的本系统综述和荟萃分析旨在验证膳食中的类胡萝卜素、维生素 A、C、E 和叶酸摄入量越高，对听力损失越有保护作用。研究方法由两名独立研究人员在电子数据库中搜索科学文章。通过构建每种维生素或抗氧化剂的简要风险度量，结合在维生素或抗氧化剂最高摄入量类别中观察到的各种变量的风险比或调整后的几率比（OR），进行元分析。结果：定量综合纳入了五项研究，涉及约 100 549 名参与者。这些研究中最高四分位数/五分位数的汇总测量值为：维生素 C 的危险比（HR）为 0.990；维生素 E 的危险比为 1.07，OR 为 0.925；叶酸的危险比为 0.921，维生素 A 的 OR 为 0.906：膳食中维生素和抗氧化剂的摄入量与患听力损失的风险成反比。摄入抗氧化剂较多的人听力阈值可能较高，尤其是摄入β-胡萝卜素的人。

Poor sleep quality impacts nearly 70 million adults in the United States, resulting in nearly 1 in 5 adults regularly utilizing some sleep aid, either prescription or over-the-counter. Common dietary supplements utilized to improve sleep quality include nitrates, melatonin, magnesium, zinc, vitamin D, and L-theanine. While underlying physiologic mechanisms support the potential impact these compounds have on sleep quality, evidence from clinical trials varies widely. Melatonin and magnesium are two of the more widely researched supplements, which have numerous studies, with conflicting results. Other compounds such as nitrates, zinc, vitamin D, and L-theanine are less supported. Additional research is needed in order to more appropriately recommend these dietary supplements for sleep improvements.
睡眠质量差影响着美国近 7000 万成年人，导致近五分之一的成年人经常使用一些睡眠辅助剂，无论是处方药还是非处方药。用于改善睡眠质量的常见膳食补充剂包括硝酸盐、褪黑素、镁、锌、维生素 D 和左旋茶氨酸。虽然基本的生理机制支持这些化合物对睡眠质量的潜在影响，但临床试验的证据却大相径庭。褪黑素和镁是研究较多的两种补充剂，它们有许多研究，但结果却相互矛盾。其他化合物，如硝酸盐、锌、维生素 D 和左旋茶氨酸，得到的支持较少。为了更恰当地推荐这些改善睡眠的膳食补充剂，还需要进行更多的研究。
