Using data from a nationwide sample of New Zealand adolescents, the authors investigated self-reported sleep hygiene, and specifically evening technology and caffeine use, and body mass index, in relation to sleep quality. Participants were 692 adolescents, predominantly European (78%), with an average age of 16 years. Just over half had poor sleep quality with a higher prevalence in girls (63.1%) than boys (44.5%), and sleep hygiene was significantly worse in girls. Caffeine after dinner was associated with increased odds of a poorer score for daytime dysfunction. A 1-hour increase in evening technology time increased the odds of poor sleep efficiency by 20%. An increase in body mass index resulted in higher odds of poor sleep efficiency and of long sleep latency. The authors discuss the implications of these findings.
