The incidence rate of hip fracture in Shiraz, Iran during 2008–2010

Abstract

This study aimed to estimate the incidence rate of hip fracture during 2008-2010 in Shiraz, Iran. Overall, the standardized age-related incidence were 329.6/100,000 in men and 1,589.7/100,000 in women. The incidence rate in females was remarkably higher than the previous studies in Iran. This study aims to determine the incidence rate of hip fracture and its possible changes during 2008-2010 in Shiraz, Iran. This study reviewed and abstracted the hospital records, demographic, and clinical data of 1,923 patients aged 50years or older with first time hip fracture admitted to private and public hospitals of Shiraz, Iran during 2008-2010 The age-adjusted incidence rate of hip fracture was determined along with association between gender, age, site of fracture, and socioeconomic status (SES) with the incidence rate. The mean age of subjects was 74.7years (±10.6years). Age-adjusted incidence rates for hip fracture, standardized to the 2000 US white male and female populations were 329.57 and 1,589.71 per 10(5), respectively, while totally it was 461.1 per 10(5). The incidence rate of hip fracture in females was higher than that of males in their 60s (1,229.2 versus 793.3), 70s (4,130.3 versus 2,835.3), and early 80s (4,506.8 versus 3,820.5) per 100,000. The hip fracture incidence in high SES area (157.1 per 100,000) followed by low SES regions (152.5 per 100,000) were higher compared to middle SES area (38.1 per 100,000) and towns around Shiraz (27.7 per 100,000) with fracture of the neck of femur being the most frequent affliction (391 per 100,000). The rate of hip fracture is increasing in the area under study particularly in women and to a greater extent in those aged 60years or older. Therefore, it is necessary to pay special attention to primary and secondary prevention of hip fracture.
