Abstract

The objective of this study was to verify if the consumption of different beverages (such as water, 100% pure fruit juice, and sugar-sweetened beverages (SSBs)) is associated with adolescents’ sleep quality. French-speaking adolescents were recruited in person and online throughout the province of Québec (Canada) from the end of March to early July 2023. Beverage consumption and sleep quality were measured using French versions of validated questionnaires specifically designed for adolescents. A total of 218 adolescents (14-17 years; 55.5% female) completed the online survey. Among caffeinated SSBs, energy drink (r_s = -0.16; p = 0.0197) and sugar-sweetened coffee (r_s = -0.33; p < 0.0001) intake was correlated with adolescents’ sleep quality. Energy drink consumption (β = -0.0048; p = 0.0005) and being male (β = 0.6033; p < 0.0001) were associated with adolescents’ sleep quality. There was an interaction between sugar-sweetened coffee intake and biological sex that was associated with adolescents’ sleep quality (p = 0.0053). Sugar-sweetened coffee consumption was correlated with adolescent girls’ abilities to go to bed (r_s = -0.21; p = 0.0203) and fall asleep (r_s = -0.28; p = 0.0020), while in boys, it was only significantly correlated with their abilities to go to bed (r_s = -0.27; p = 0.0069). Public health interventions aimed at adolescent boys should primarily target lowering energy drink consumption, while those aimed at girls should prioritize sugar-sweetened coffee intake to possibly improve their sleep quality.
