Effect of Personalized Nutrition Guidance on the Birth Rate of Fetal Macrosomia in Chinese Population: A Meta-analysis of Nine Randomized Controlled Trials
Abstract
The aim of the study was to perform a systematic review and meta-analysis of randomized controlled trials (RCTs) evaluating the efficacy of personalized nutrition guidance on birth rate of fetal macrosomia in the pooled studies. A comprehensive search was conducted to identify all eligible studies using the databases of PubMed, MEDLINE, Embase, Wanfang, Chongqing Weipu Database for Chinese Technical Periodicals and China National Knowledge Infrastructure and reference lists of relevant articles. The methodological quality of the included trials was assessed based on the Jadad scale. We used risk ratios (RRs) to assess the strength of the association, and 95 % confidence intervals (CIs) to evaluate the precision of the estimate. Heterogeneity, publication bias, and sensitivity analysis were also explored. A total of nine RCT studies, including 7,458 pregnant women, were included in the present meta-analysis. The overall results showed that personalized nutrition guidance significantly reduced the birth rate of fetal macrosomia (RR 0.289, 95 % CI 0.184-0.453, P < 0.01) in Chinese population. Simultaneously, publication bias was detected in this meta-analysis. The personalized nutrition guidance can significantly reduce the birth rate of fetal macrosomia. However, due to the limited number of RCTs, especially those with large sample size and multicenter that were quantitatively insufficient, further studies of high quality are required.
