title: Trend in hip fracture incidence and mortality in Korea: a prospective cohort study from 2002 to 2011.
abstract: This prospective longitudinal cohort study was to assess the 10-yr hip fracture incidence and mortality trend of person ≥50 yr of age between 2002 and 2011 of eight hospitals in Jeju Island. Sex-specific incidence rate (per 100,000 person-years) were calculated based on that estimated for the population in the United States in 2008. Poisson and logistic regressions were used to examine trends in incidence and mortality. There was a 101% increase in the number of hip fractures from 151 in 2002 to 304 in 2011. The crude incidence of hip fractures in the Jeju population ≥50 yr of age increased from 126.6/100,000 to 183.7/100,000. The fracture incidence in the population standardized to the 2008 population in the United States increased from 100.6/100,000 for men and 194.4/100,000 for women in 2002 to 114.2/100,000 for men and 278.4/100,000 for women in 2011. The annual increasing incidence rate of hip fracture was 4.3% (5.3% in women and 2.2% in men). Poisson regression did not show significant trends in the mortality rates for all age groups or for both genders. The total number of hip fractures increased two-fold and the incidence rate of hip fractures increased markedly during the 10-yr study period.
