Decreasing hip fracture rates among older adults in Chile, 2001–2019

Summary Our aim was to analyze trends in hip fracture rates in people aged ≥ 65 years, from 2001 to 2019 in Chile. Age-standardized incidence rates decreased significantly in both genders over the study period. Purpose To describe and analyze the characteristics and trends of osteoporotic hip fractures in Chile from 2001 to 2019, by age and sex. Methods We assessed hip fractures in people aged ≥ 65 years using data from the hospital discharge register of Chile’s Department of Statistics and Health. The Joinpoint regression analysis software was used to perform a trend analysis. Results From 2001 to 2019, a total of 107.972 patients aged ≥ 65 years were hospitalized in Chile with a diagnosis of hip fracture (S72.0, S72.1, and S72.2). 77.4% of the patients were females, and 63.7% were adults aged ≥ 80 years. The average annual incidence rate over this period was 358.3/100.000 in the whole population (95% CI: ± 12.8), 195.2/100.000 in men (95% CI: ± 9), and 482/100.000 in women (95% CI: ± 15.5). After an adjustment for age, hip fracture rates decreased annually on average by 1.0% ( p
