This study aims to investigate the population-based incidence of clavicle fracture and the related risk factors in China.


All the data on clavicle fractures were available from the China National Fracture Survey (CNFS) database performed in 2015. In the CNFS, all eligible household members were sampled from eight provinces, 24 urban cities, and 24 rural counties in China, using stratified random sampling and the probability proportional to size method. Questionnaires were sent to every participant for data collection. Information on age, gender, height, weight, ethnic group, education, professional, smoking, alcohol consumption, sleeping time per day, dietary habits, and others was collected. Fracture case was identified by patients’ self report and further confirmation by medical data.


A total of 512,187 valid questionnaires were collected, and relevant data were extracted and analyzed. There were 89 patients with 89 clavicle fractures in 2014, indicating that the incidence was 17.4 (95%CI, 13.8–21.0) per 100,000 person-years. Traffic accidents and falls were the most predominant cause for clavicle factures, leading to 91.0% of all the injuries. Over 85% of them occurred on the road and at home. Age of 45–64, average sleep time < seven hours/day, smoking, alcohol consumption and history of previous fracture were identified as independent risk factors for clavicle fracture. Overweight (BMI, 24.0–27.9) was a significant protective factor, which was estimated to reduce 72% of the clavicle fractures, compared to normal BMI (18.5–23.9).


Public health policies focusing on decreasing alcohol consumption, smoking cessation, and encouraging individuals to obtain sufficient sleep should be implemented. Middle-aged individuals with previous history of fracture should strengthen the awareness of prevention and health care and decrease risky activities to reduce the clavicle fractures.
