Medical Research: What is the background for this study?
Dr. Cheungpasitporn: High-fructose corn syrup consumption in the form of sugar-sweetened soda has dramatically increased worldwide and associated with risk factors for chronic kidney disease (CKD) including diabetes mellitus (DM) and metabolic syndrome. Recently, artificial sweeteners have become commonly used in soda marketed as ‘diet’ alternatives. Recent studies have demonstrated that diet soda consumption may also be associated with weight gain, metabolic syndrome and cardiovascular disease. The risks of CKD in individuals with sugar-sweetened or diet soda consumption, however, were conflicting. We therefore conducted a meta-analysis to assess the associations between CKD and the consumption of sugar sweetened and diet soda. The findings of our study were recently published in Nephrology (Carlton). 2014; 19(12):791-7.
Medical Research: What are the main findings?
Dr. Cheungpasitporn: Five studies (2 prospective cohort studies, 2 cross-sectional studies and a case-control study) were included in our analysis of the association between consumption of sugar-sweetened soda (≥1-2 drinks of sugary soda/day) and CKD. We found an overall 1.58-fold increase CKD risk in individuals who regularly consumed sugar-sweetened soda with the pooled risk ratio (RR) of 1.58 (95% CI 1.00–2.49). Four studies (2 prospective cohort studies, a cross-sectional studies and a case-control study) were included to assess the association between CKD and diet soda consumption (≥1-2 drinks of diet soda/day). Despite a trend of chronic kidney disease risk in individuals with diet soda consumption with the pooled RR of 1.33 (95% CI 0.82–2.15), this association was not statistically significant.
