The Multidimensional Correlates Associated With Short Nocturnal Sleep Duration and Subjective Insomnia Among Taiwanese Adolescents

Study Objectives: The aim of this study was to examine the correlates associated with short nocturnal sleep duration and subjective insomnia, including individual factors, family factors, peer factors, school factors, and the problematic use of high-tech devices among a large-scale representative population of Taiwanese adolescents. Design: Cross-sectional study. Setting: A total of 23 junior high and 29 senior high/vocational schools were randomly selected across southern Taiwan. Participants: Eight thousand four adolescent students. Interventions: N/A. Measurements and Results: The multidimensional correlates associated with short nocturnal sleep duration and subjective insomnia were examined using X-2 automatic interaction detection analysis and logistic regression analysis models. The results indicated that an older age, self-reported depression, being in the third year of school, drinking coffee at night, and problematic Internet use were significantly associated with short nocturnal sleep duration in adolescents. Furthermore, self-reported depression, low school affinity, high family conflict, low connectedness to their peer group, and problematic Internet use were associated with subjective insomnia in adolescents. Conclusions: The results of this study indicate that a variety of individual, family, peer, and school factors were associated with short nocturnal sleep duration and subjective insomnia in adolescents. Furthermore, the correlates of short sleep duration were not identical to those of subjective insomnia. Parents and health professionals should be wary of sleep patterns among adolescents who have the identified correlates of short nocturnal sleep duration and subjective insomnia.
