Abstract

Abstract: Objectives: To examine whether usual beverage intake was associated with sleep timing, duration, and fragmentation among adolescents. Methods: The study population included 528 Mexico City adolescents enrolled in a longitudinal study. Beverage intake over the last week was assessed with a food frequency questionnaire. The following beverage groups were analyzed: milk, sweetened milk, regular soda, coffee/tea, 100% fruit juice, commercial fruit juice with sugar, fruit drink/flavored water with sugar, and plain water. Sleep timing, duration, and fragmentation were assessed with 7-day actigraphy. Overall and sex-stratified linear regression was conducted with sleep characteristics as separate outcomes and quantiles of energy-adjusted beverage intake as exposures, accounting for sex, age, maternal education, physical activity, and smoking. Results: The mean age (SD) was 14.4 (2.1) years; 48% were male. The most commonly consumed drinks were water, milk, soda, and fruit juice with added sugar (energy-adjusted mean = 666 (557) mL per day, 360 (278) mL per day, 225 (251) mL per day and 203 (263) mL per day, respectively). In overall regression analysis, soda was associated with later sleep timing; those in the 4 th (highest) quartile of soda consumption had a 19 minute later weekday sleep timing than those in the lowest quartile [95% CI 1, 37]. Among boys, milk and water consumption were each associated with longer weekday sleep duration (25 [1, 48] and 26 [4, 47] more minutes, respectively in the 4 th compared to the 1 st quartile); and higher 100% fruit juice consumption was related to earlier weekday sleep timing (−22 [−28, 1] minutes in the 1 st compared to the last quantile; P trend = 0.03). Among girls, soda was associated with higher sleep fragmentation (1.6 [0.4, 2.8] % in the 4 th compared to the 1 st ), and coffee/tea consumption was related to shorter weekend sleep duration (−23 [−44, −2] minutes in the 4 th compared to the 1 st ). Conclusions: Higher soda intake was associated with later sleep midpoint in boys and girls, while other beverages were associated with sleep in a sex-specific manner. Among girls, adverse associations with sleep were observed for caffeinated drinks only, while boys with higher consumption of water, milk, and natural juice had evidence of healthier sleep.
