Geographic and seasonal variations in hip fracture incidence in Sweden: a nationwide population-based study

Geographic disparities in first hip fracture incidence were observed among both women and men in Sweden, with the highest rates in the northernmost counties. These differences could not be fully explained by uneven distribution of the risk factors examined in this study. Additionally, sex differences were noted in the counties with the highest and lowest incidence rates. Seasonal variation in hip fracture incidence was evident.
