BackgroundSugar-sweetened beverages have been associated with weight gain and type 2 diabetes [1-3]. These beverages have a high energy content and contain many rapidly absorbable carbohydrates. Moreover, high fructose corn syrup, a sweetener used to flavour soft drinks, increased dietary glycaemic load and serum triglyceride levels, and may increase insulin resistance [4,5]. Soft drink consumption is associated with CVD risk [6,7], although the role of soft drink consumption in the development of coronary atherosclerosis is not exactly known yet. Coronary artery calcium (CAC) is a marker of subclinical coronary atherosclerosis  as well as a predictor of future coronary heart disease events in a wide range of age groups [9,10].
This study investigated the association of regular soft drink consumption between 2011 and 2013 with the prevalence of subclinical atherosclerosis in 22,210 Korean men and women. Regular soft drinks were defined as sugar-sweetened carbonated beverages and subclinical atherosclerosis was measured by CAC, which was determined by computed tomography (CT). People with missing data, a history of CVD, cancer or diabetes or an extraordinary low or high energy intake were excluded. Dietary consumption was assessed using a 106-item self-administered FFQ, regarding the past year. Participants were categorised as per week no drinks, <1 drink, 1-3 drinks, 3-5 drinks, more than 5 drinks.
- Average softdrink consumption was 1.2 drinks per week. 70% of the participants consumed sugar-sweetened carbonated beverages and 5% consumed ≥ 5 per week.
- The prevalence of detectable CAC was 11.7%.
- Participants with a higher intake had higher glucose (P = 0.01), insulin (P < 0.001), HOMA-IR (P < 0.001), SBP (P < 0.001), DBP (P < 0.001), total cholesterol (P = 0.002), triglyceride (P < 0.001), LDL-c levels (P < 0.001) and hsCRP (P < 0.001) but lower HDL-c levels (P < 0.001).
- CAC score ratio for people consuming ≥ 5 sugar-sweetened carbonated beverages per week compared to those who did not consume any of these was 1.86 (95% CI: 1.13-3.07), corrected for age, sex, center and year of screening examination (P trend = 0.04).
- The CAC score ratio remained significant after adjustment for potential confounders (1.70, 95% CI: 1.03-2.81, P trend = 0.10).
- The multivariable odds ratio for detectable CAC for people consuming ≥ 5 sugar-sweetened carbonated beverages per week compared to those who did not consume any of these was 1.27 (95% CI: 1.02-1.59).
- When 6,613 participants were excluded because they did not drink any sugar-sweetened carbonated beverage, the relation with CAC became more evident (multivariable CAC ratio was 1.97, 95% CI: 1.19-3.28).
ConclusionHigh sugar-sweetened carbonated beverage consumption was associated with asymptomatic subclinical coronary atherosclerosis in young and middle-aged adults and may therefore be cardiovascular hazard.
