abstract="OBJECTIVE: To examine the association between sleep quality and military training  injury (MTI) in recruits during basic combat training (BCT). <br><br>METHODS: Participants  were new recruits undergoing 12-week military BCT in China. Sleep quality was  measured by the Pittsburgh Sleep Quality Index (PSQI). Participants were classified  into two groups based on their sleep quality (group 1, good sleep, PSQI score <7;  group 2, poor sleep, PSQI score ≥7) at the start of BCT. Logistic regression  analysis was conducted to test whether baseline PSQI score was associated with MTI  incidence during BCT. <br><br>RESULTS: A total of 563 participants were included. The  incidence of MTI was significantly lower in group 1 (48/203, 23.6%) than in group 2  (150/360, 41.7%) (p<0.001). Logistic regression analysis showed that the odds of MTI  were 2.307 times higher in group 2 than in group 1 without adjusting for  confounders: OR=2.307, p<0.001. When the model was adjusted for age, ethnicity,  educational level and family income (OR=2.285) or for the previous confounders plus  body mass index (OR=2.377), the results were similar (both p<0.001). Analysis of the  types of initial MTI showed that group 2 had about 2.1 times higher odds of soft  tissue injury than group 1 (p<0.001 in all the three models). <br><br>CONCLUSION: Sleep  quality before BCT influences the incidence of MTI, especially of soft tissue  injury.<p /> <p>Language: en</p>",
