Abstract
This study aimed to investigate the population-based incidence rate of ankle fracture and associated risk factors in China. All the data on ankle fractures were available from the China National Fracture Survey (CNFS) conducted between January and May in 2015. All eligible household members were sampled from 8 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 and quality control was accomplished by our quality control team members. A total of 512187 valid questionnaires were collected and relevant data were abstracted and analyzed. One hundred and ninety patients sustained 193 ankle fractures in 2014, indicating the incidence rate was 37.1 (95% CI, 31.8–42.4)/100,000 person-year. Alcohol consumption, living alone and average sleep time <7 h/d were identified as independent risk factors for ankle fracture in both males and females. Previous history of fracture was identified as significant risk factor of ankle fracture in females but not in males. Therefore, specific public health policies focusing on decreasing alcohol consumption and encouraging individuals to obtain sufficient sleep should be implemented. Individuals living alone should focus more on healthcare, especially in those with previous fracture.
Highlights
IntroductionSome less-severe fractures treated by conservative methods might be missed out
Ankle fracture is the most common injury in the department of emergency and orthopaedics, accounting for 46.7% of tibial/fibula fractures and 7.6% of all fractures[1]
Results showed 76.8% of ankle fractures were caused by slip, trip or fall, and 72.1% of all ankle fractures occurred at home and on the road around
Summary
Some less-severe fractures treated by conservative methods might be missed out This national survey system only collected the basic data on fractures (e.g. age, gender and fracture occurrence timing), but without any information on bone site, type of fracture, injury mechanism and related risk factor (geographical location, socioeconomic and lifestyles). We designed and performed the China National Fracture Study (CNFS) in 2015 years to investigate the population-based incidence rates and related socioeconomic and lifestyles for traumatic fracture of all body www.nature.com/scientificreports/. Data on ankle fractures were extracted from the CNFS database and we had 2 aims: 1, to report the national population-based incidence of ankle fracture in China and 2, to explore the related risk factors in term of demographics, socioeconomics, and lifestyles
