Association between cumulative intake of sugar-sweetened and artificially sweetened beverages and progression of coronary calcification: Insights from the CARDIA study

Abstract

Background and aims

This study investigates the relationship between the cumulative intake of artificially sweetened beverages (ASBs) and sugar-sweetened beverages (SSBs) during young adulthood and the progression of coronary artery calcium (CAC) by midlife, using data from the Coronary Artery Risk Development in Young Adults study.

Methods and results

We included 2,466 participants with CAC measurement via computed tomography at the 15th, 20th, and 25th year follow-ups. Dietary intake was assessed using the CARDIA Diet History at baseline and years 7. Cumulative average beverage intake was calculated and categorized. Multivariable Cox regression models adjusted for demographic, lifestyle, and cardiovascular risk factors assessed associations between beverages consumption and CAC progression. Among the included participants, 1107 (44.9 %) were male, 1439 (58.4 %) were white, and the average age was 40.4 years with a standard deviation of 3.5 years. Over a 9.2±1.8-year follow-up, CAC progression was recorded in 715 participants. Higher cumulative ASBs intake was associated with increased CAC progression risk, with hazard ratios (95%CI, P-value) for low and high ASBs consumption being 1.35 (1.14, 1.60; P < 0.001) and 1.54 (1.15, 2.07; P < 0.001) compared to non-consumers. Participants consuming >2 servings/day of SSBs had a 37 % higher CAC progression risk (HR 1.37, 95 % CI 1.14–1.64, P < 0.001). However, no significant association was found between SSB consumption and CAC progression after adjusting for confounders.

Conclusions

Prolonged consumption of beverages, especially ASBs, in young adults is linked to an increased risk of CAC progression.
