Background and objective: Data concerning the incidence of fractures in Italy have been displayed since year 2000 by analysing hospital discharge records (HDRs). However, the influence of seasonal and environmental factors on fracture events in the Italian population has not yet been assessed.
Methods: We have analyzed HDRs for primary diagnosis of hip, vertebral, forearm, humeral and knee fractures in Italy from year 2007 to 2009. Inferential statistics have been performed to test the influence of the different seasons on the incidence of hip and non-hip fractures, taking into account also the region where fractured people lived, both for men and women.
Results: Both the incidence hip and non-hip fractures in winter and autumn is significantly higher than that observed in spring and summer. The incidence of hip and non-hip fractures is higher in Northern Italian Regions than Central and Southern both in males and females.
Conclusion: Our analyses show that the incidence of hip and non-hip fractures is influenced by seasons in a statistically significant way, being higher in winter and autumn. This finding could explain why the incidence of both hip and non-hip fractures is higher in northern Italian regions than in southern and central ones.
