ABSTRACT
BACKGROUND:
Contemporary technology and multiple device use may link to increased body mass index (BMI). The sleep-obesity relationship is inconsistent in adolescents. Sleep duration and quality may have crucial connections to obesity development, particularly in adolescents where sleep alterations are common. Elevated BMI in adolescents may influence academic performance and aspiration, but data are limited.OBJECTIVES:
The objectives of this study was to assess the linear associations between BMIâ z-score and (i) quantity/type of technology used; (ii) sleep quantity/quality and (iii) academic performance/aspiration.METHODS:
Consenting adolescents (n = 624; 64.9% girls, aged 11-18 years) were recruited. The Schools Sleep Habits Survey and Technology Use Questionnaire were administered. Objective measures of height/weight were obtained.RESULTS:
Quantity of technology was positively associated with BMIâ z-score ß = 0.10, P < 0.01. Those who always engaged in video gaming had significantly higher BMIâ z-score vs. never-users, ß = 1.00, P < 0.001. Weekday sleep duration and sleep onset latency were related to BMIâ z-score, ß = -0.24, P < 0.001 and ß = 0.01, P < 0.001, respectively. An inverse linear association was observed between BMIâ z-score and academic performance, ß = -0.68, P < 0.001.CONCLUSIONS:
If confirmed prospectively, reducing bedtime use of technology and improving sleep hygiene in adolescents could be an achievable intervention for attenuating obesity with potentially positive effects on academic performance.Mots clés
