ai Chi Reduces Insomnia in College Students: Exploring Inflammatory Factor Roles

Insomnia: measured by PSQI scale. The scale was developed by Buysse et al, a neurologist at the University of Pittsburgh, USA, and has an overall internal consistency Cronbach's ɑ coefficient of 0.83.The scale was used to assess the quality of sleep of an individual in the last month, and consists of 19 self-assessed and 5 other-assessed entries, for a total of 24 items, where the 19th entry and the five other-assessed entries do not participate in the scoring. The 18 scoring items include seven dimensions: subjective sleep quality, time to sleep, sleep efficiency, sleep disorders, hypnotic drug use, and daytime functioning. Each dimension is scored on a scale of 0-3, and the cumulative score is the total PSQI score, which ranges from 0-21, with higher scores indicating poorer sleep quality, and PSQI scores greater than 7 are considered clinical insomnia.

Physical activity: was measured using the Physical activity rating scale-3 (PARS-3). The scale has a revised by Liang Deqing et al. with a retest reliability of 0.82. The scale determines the amount of exercise in terms of intensity, time, and frequency of participation in physical activities. Exercise volume = exercise intensity × time × frequency, intensity and frequency are scored on a scale of 1 to 5, assigning 1 to 5 points respectively, and time is scored on a scale of 1 to 5, assigning 0 to 4 points respectively. The score range of the scale was 0-100 points, and the score of ≤19 points was low exercise, 20-42 points was medium exercise, and ≥43 points was high exercise.
