| Objective To investigate the risk factors for hip fracture in women and men aged 50 years and older. Methods A matched case-control study was carried out in the urban area of Beijing from Jan.1994 to May 1996. A total number of 201 cases having had hip fracture were identified by X-ray films in four hospitals of Beijing. Four hundred and two neighbourhood controls were individually matched with these cases by age and sex. Data were analyzed by statistical technique of Chi square test and conditional logistic regression. Results In a multiple conditional logistic regression model, low dietary calcium intake, previous history of more sedantary position,lack of calcium supplement, low body mass index, current low physical exercise, never living in rural, sedentary position at work,previous fractures of any type after the age of 50, history of family hip fracture and diabetes mellitus were significantly associated with increased risk of hip fracture. In addition,hip fracture was related to the age of menopause and duration of breastfeeding in women,as well as body height in men.
