Population-level impact of osteoporotic fractures on mortality and trends over time: a nationwide analysis of vital statistics for France, 1968-2004.
Osteoporotic fractures are one of the leading causes of death in the elderly population, but mortality may have been reduced by the advances in management and prevention during recent decades. The authors analyzed the population-level impact of these fractures on mortality in France from 1968 to 2004. About 20 million death certificates registered in metropolitan France from 1968 to 2004 were analyzed. Osteoporotic fractures were identified by using a previously developed methodology. Age-specific and standardized mortality rates were calculated by site of fracture and sex, and time trends were evaluated. Associated causes of death were compared between the extreme periods of the study by the observed/expected pairs method; 440,890 (2.2%) death certificates reported an osteoporotic fracture. Osteoporotic fractures overall, particularly hip and skull fractures, declined by half during the study period, exceeding the decline in general mortality and resulting in fracture-deceased subjects being older. However, pelvis, vertebral, and rib fractures became more frequent. Associated causes of death increased with time, except for decubitus ulcers, indicating a change in the pattern of the death process. Despite a 50% decline, osteoporotic fractures still have a significant impact on mortality. The pattern of the death process has changed, with an increased role for comorbidities.
