Background Low-calorie sweetened beverages (LCSBs) are commonly used as a lowercalorie alternative to sugar-sweetened beverages (SSBs) by individuals with type 2 diabetes. However, little is known about how intake of LCSBs is related to dietary intake and cardiometabolic health, particularly among youth. Objective To test the hypothesis that having higher baseline LCSB intake and increasing LCSB intake over 2 years of follow-up are associated with poorer dietary intake and higher cardiometabolic risk factors among youth enrolled in the Treatment Option for Type 2 Diabetes in Adolescents and Youth (TODAY) study. Design Secondary, exploratory, analysis of baseline and longitudinal data from the TODAY study, which was a randomized, multisite trial conducted from 2004 to 2012, to compare effects of 3 interventions (metformin alone, metformin rosiglitazone, and metformin intensive lifestyle intervention) on glycemic control in youth with type 2 diabetes. Participants/setting The study included 476 children and adolescents (10-17 years, mean body mass index 34.9 +/- 7.8 kg/m(2)), who were participants in the multicenter (n = 15) TODAY study. Main outcome measures Diet was assessed using a food frequency questionnaire. Differences in energy intake, macronutrients, food group intakes, and cardiometabolic biomarkers were evaluated in 3 groups of LCSB consumers at baseline (low [1-4 servingsiwk], medium [5-11 servingsiwk], and high [>= 12 servingsiwk]), each compared with nonconsumers, and between 4 groups of change in LCSB intake (nonconsumption at start of study and nonconsumption after 2 years, increase in consumption after 2 years, decrease in consumption after 2 years, and high consumption at start of study and high consumption after 2 years). Statistical analyses performed Multivariable linear regression was performed at baseline and longitudinally over 2 years of follow-up. Results Energy (kilocalories), fiber, carbohydrate, total fat, saturated fat, and protein intake (grams) were higher among high LCSB consumers compared with nonconsumers at baseline. No associations were observed between LCSB consumption and cardiometabolic risk factors at baseline. Change in LCSB intake between baseline and follow-up was not associated with change in energy intake or cardiometabolic risk factors. Participants who decreased LCSB consumption reported greater increases in sugar intake (18.4 +/- 4.8 g) compared with those who increased LCSB consumption (5.7 +/- 4.9 g) or remained high LCSB consumers (5.9 +/- 7.4 g), but this trend was not statistically significant after a correction for multiple testing. Conclusions LCSB consumption was associated with higher energy intake in youth with type 2 diabetes, with the highest energy intakes reported in high LCSB consumers. Those who reduced LCSB consumption tended to report greater increases in sugar intake during follow-up, but further studies are needed to better understand this trend.
