Abstract

The development of preventive strategies for hip fractures requires better identification of risk factors. The MEDOS study was designed to study prospectively the incidence of hip fracture in 14 centres from six countries and characterise risk factors. At one centre (Toulouse), data were gathered from questionnaires completed by 386 cases of hip fracture aged over 50 years and 848 age- and sex-matched controls over a 12-month period. Of the 935 variables of the MEDOS questionnaire, 235, grouped into 56 items, were statistically analysed. Odds ratios (and 95% confidence intervals) were estimated for each variable from a multiple stepwise logistic regression model. The population comprised 19.2% men and 80.8% women, with a mean age of 80 +/- 8.8 years; 80% were living in an urban area and 76% with their family. Of the 17 significant variables, moderate excess weight and a high nutritional intake of calcium were associated with a decreased risk of hip fracture. Loss of autonomy, a higher height than normal (> 1SD), and a history of previous fractures significantly increased the risk of fracture. Interestingly, all these variables accounted for only 18% of the risk of hip fracture.
