Abstract

Background and aims: Anthocyanins (ACNs) are water-soluble plant pigments belong to flavonoids with beneficial effects on health and disease prevention. Some studies have examined the effect of ACNs on anthropometric and body composition indices, but the findings were inconsistent. This systematic review and meta-analysis aimed to investigate the effect of ACNs and sources rich in anthocyanins on body mass index (BMI), body weight (BW), waist circumference (WC), hip circumference (HC), waist-hip ratio (WHR), percentage of fat mass (PFM) and fat free mass (FFM).

Methods: PubMed, Web of Science, Scopus, and Google Scholar were searched with no limitation until May 2021 to find relevant randomized controlled clinical trials (RCT). The risk of bias was assessed utilizing Cochrane collaboration's tool. Weighted mean differences (WMD) and 95% confidence intervals (CIs) were obtained using a random effects model.

Results: A total of 31 RCTs (with 0.77-640 mg/day of ACNs supplementation for 28-90 days) with 1438 participants were included. No significant effect was found in BMI, WC, HC, WHR, PFM and FFM after ACNs consumption.

Conclusions: The results showed that ACNs did not significantly affect anthropometric and body composition parameters. Further high-quality RCTs are required to validate these findings.

食用花青素会影响体重和身体组成吗？随机对照试验的系统回顾和荟萃分析。

背景和目的：花青素（ACNs）是一种水溶性植物色素，属于黄酮类化合物，对健康和疾病预防有益。一些研究探讨了花青素对人体测量和身体成分指数的影响，但结果并不一致。本系统综述和荟萃分析旨在研究 ACNs 和富含花青素的来源对体重指数（BMI）、体重（BW）、腰围（WC）、臀围（HC）、腰臀比（WHR）、脂肪量百分比（PFM）和无脂肪量（FFM）的影响：在 2021 年 5 月之前，对 PubMed、Web of Science、Scopus 和 Google Scholar 进行了无限制检索，以找到相关的随机对照临床试验（RCT）。利用 Cochrane 协作工具评估了偏倚风险。采用随机效应模型得出加权平均差（WMD）和 95% 置信区间（CI）：共纳入了 31 项 RCT（ACNs 补充量为 0.77-640 毫克/天，持续 28-90 天），1438 人参与了研究。结果：共纳入了 31 项研究（每天补充 0.77-640 毫克 ACNs，持续 28-90 天），1438 名参与者，结果显示，摄入 ACNs 后，BMI、WC、HC、WHR、PFM 和 FFM 均无明显影响：结果表明，ACNs 对人体测量和身体成分参数没有明显影响。需要进一步开展高质量的研究实验来验证这些发现。
