Association of Sugar-Sweetened Carbonated Beverage with the Alteration in Left Ventricular Structure and Diastolic Function

Background High consumption of sugar-sweetened carbonated beverage (SSCB) has been associated with multiple metabolic risk factors for cardiovascular disease. However, published data is scarce regarding the influence of SSCB consumption on left ventricular (LV) structure and diastolic function. The present study is to investigate the association of SSCB consumption with alteration in LV structure and diastolic function. Method Study subjects were 46,417 Koreans who received echocardiography as an item of health checkup. They were categorized into 4 groups by SSCB consumption based on one serving dose (200 ml) with never/almost never, <1 serving/week, 1 <= serving/week <3 and >= 3 serving/week. Multivariate logistic regression analysis was used in calculating adjusted odd ratio (OR) and 95% confidence interval (CI) (adjusted OR [95% CI]) for left ventricular hypertrophy, increased relative wall thickness (IRWT) and impaired LV relaxation with each group (reference: never/almost never consumption). Subgroup analysis was conducted by age of >= 40 and Result Compared with never/almost never consumption, SSCB consumption >= 3 serving/week had the higher mean levels in body mass index, blood pressure and triglyceride despite of younger age. In fully adjusted analysis, SSCB consumption >= 3 serving/week was associated with IRWT (1.14 [1.02-1.27]) and impaired LV relaxation (1.23 [1.08-1.41]). This association was reinforced in age subgroup >= 40 years, but not statistically significant in age subgroup Conclusion SSCB consumption >= 3 serving/week was associated with the increased probability of IRWT and impaired LV relaxation.
