Our sample included 35 613 people aged 60 years or above. We analysed two binary outcome variables that were collected at each wave, including whether a respondent had any falls in the last 2 or 3 years, and if so, whether a respondent experienced any injurious falls that warranted seeking medical treatment. The explanatory variables included individual-level sociodemographic characteristics, physical function and health status. We conducted both descriptive and multivariate logistic analyses.Results We found no significant trend for falls after adjusting for individual-level factors, while significant regional variations in falls existed with higher fall prevalence in the central and western areas, compared with the eastern area. We detected a significant descending trend of injurious falls between 2011 and 2018 and identified the northeastern region with the lowest rates of injurious falls during the study period. Our study also revealed significant risk factors for falls and injurious falls, such as chronic conditions and function limitations.Conclusions Our results indicated no temporal trend of falls, a declined trend of injurious falls, and significant regional variations in the prevalence of falls and injurious falls in 2011–2018. These findings have important implications for prioritising areas and subpopulations to prevent falls and injuries among China’s elderly population.Data are available in a public, open access repository.
