Effects of Adverse Events and 12-Week Group Step Aerobics on Sleep Quality in Chinese Adolescents.

BACKGROUND

In China, sleep disorders have become a public health concern. This study aimed to model the relationship between adverse events and sleep quality, as well as the effect of group step aerobics on sleep quality.

METHODS

The modeling was built on surveying 2760 16-19-year-old adolescents. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality, and the Adolescent Self-rating Life Events Checklist (ASLEC) was used to evaluate adverse events. Adolescents with sleep disorders (PSQI ≥ 8) were randomized into the control ( = 26) and exercise ( = 26) groups. The exercise group participated in 12-week step aerobics, and the 300 min weekly volume is compliant with the WHO physical activity guidelines.

RESULTS

The double Poisson distribution was chosen to fit the data. ASLEC had a nonlinear relationship with the PSQI. Participants in the exercise group slept better ( < 0.05) from the eighth week until the end of the study. A random adolescent, therefore, has a 92.5% probability of experiencing improved sleep quality after 12 weeks of step aerobics.

CONCLUSIONS

Intervention should be implemented before adverse events accumulate. An active lifestyle should be a preparedness strategy for increasing the resilience of adolescent mental health in the face of adversity.
