To systematically assess systematic reviews and meta-analyses investigating the association of breastfeeding with ECC.
A systematic search was carried out from MEDLINE® (PubMed), EMBASE, the Cochrane Central Database, OVID, Joanna Briggs Institute Database of Systematic Reviews and Implementation Reports and Epistemonikos Databases up to November 2019. Data extraction was carried out by two investigators. ROBIS tool was used for quality assessment of included systematic reviews.
Four systematic reviews were found assessing the correlation of breastfeeding with ECC. Findings were grouped into four categories, according to the duration, frequency, pattern, and comparison of feeding habits. Two systematic reviews assessing duration of breastfeeding above the age of 12 months had odds ratios of 1.86 and 1.99, showing positive correlation with ECC while nocturnal breastfeeding showed highest odds ratio of 7.14. Of the four included reviews, three had low risk of bias and one had unclear risk of bias.
Breastfeeding beyond the age of 12 months, accompanied by nocturnal feeding, had a positive association with ECC. Further research is warranted for assessment of diurnal and nocturnal sleep-time breastfeeding habits, together with the role of enamel defects (hypoplasia), and the risk of ECC.
系统评估探讨母乳喂养与婴幼儿龋（ECC）相关性的系统评价和荟萃分析。
从 MEDLINE®（PubMed）、EMBASE、Cochrane 中央数据库、OVID、Joanna Briggs 研究所系统评价数据库和实施报告数据库以及 Epistemonikos 数据库中进行了系统检索，检索时间截至 2019 年 11 月。两名研究者进行了数据提取。使用 ROBIS 工具对纳入的系统评价进行质量评估。
共发现 4 篇评估母乳喂养与 ECC 相关性的系统评价。根据喂养习惯的持续时间、频率、模式和比较，将研究结果分为 4 类。2 篇评估母乳喂养持续时间超过 12 个月的系统评价的比值比分别为 1.86 和 1.99，表明与 ECC 呈正相关，而夜间母乳喂养的比值比最高，为 7.14。纳入的 4 篇综述中，有 3 篇的偏倚风险较低，1 篇的偏倚风险不明确。
母乳喂养持续时间超过 12 个月，伴有夜间喂养，与 ECC 呈正相关。需要进一步研究日间和夜间睡眠时母乳喂养习惯以及牙釉质发育不全（发育不良）的作用和 ECC 的风险。
