Abstract
Context
The prevalence of type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVDs) is increasing in Asia and several countries are adopting preventive policies to reduce consumption of sugar-sweetened beverages (SSBs). However, evidence on the relation between SSB consumption and cardiometabolic health in Asian populations has not been summarized.
Objective
In this systematic review, the associations between consumption of SSBs and cardiometabolic outcomes, including obesity, T2DM, and CVD, are examined in Asian populations.
Data sources
The PubMed, Scopus, and Web of Science databases, and gray literature were searched up to October, 2020 to identify relevant articles.
Data extraction
Two investigators independently extracted data from included studies.
Data analysis
When sufficient studies were available, a random-effects meta-analysis was used to calculate the pooled estimates (expressed as risk ratio [RR] and 95% confidence interval [CI]). Heterogeneity was tested and quantified using the Cochrane Q test and I2 statistic, respectively.
Results
Of the 17 studies included, 8 provided results about measures of adiposity (3 on weight change, 4 on body mass index (BMI), 2 on percent body fat, and 1 on abdominal obesity), 6 reported results about T2DM, and 3 reported on different CVD outcomes. High SSB consumption was significantly associated with greater weight gain and with a higher risk of selected CVD outcomes as compared with low consumption. In the meta-analysis, high SSB consumption was associated with greater T2DM risk before (RR, 1.51; 95%CI, 1.15–1.98 for highest vs lowest category; I2 = 76%) and after (RR, 1.38; 95%CI, 1.09–1.73; I2 = 56%) adjustment for BMI.
Conclusions
These findings suggest that high SSB consumption is directly associated with weight gain, risk of T2DM, and, possibly, selected CVD outcomes in Asian populations. Public health strategies to reduce SSB consumption in Asian countries are warranted.
