Risk factors for proximal femur osteoporosis in men aged 50 years or older.

Abstract

The objective of this study was to analyze the risk factors for osteoporosis in 325 volunteer men aged 50 years or older. Participants completed questionnaires including demographic and social information, personal medical history, maternal and paternal history of bone fracture after the age of 50 years, smoking habit, alcoholic beverage consumption, calcium intake and present and past physical activities. The individuals were submitted to bone densitometry of the femoral neck and to anthropometric measurements. The chi2 test and multiple logistic regression were used to evaluate the association between the independent variables and the presence of osteoporosis. We concluded that the independent risk factors for osteoporosis were body mass index, present practice of physical/leisure activity (last 12 months), age, present and past smoking habit, no current thiazide diuretic use, white race and maternal history of fracture after the age of 50 years.
