PURPOSE: to evaluate the prevalence of osteoporosis in climacteric women and analyze the influence of general and reproductive risk factors on bone mineral density. METHODS: a cross-sectional study with the evaluation of the 473 hospital records of climacteric women followed up at the Menopause Outpatient Facility of CAISM/Unicamp, between 03/28/2000 and 04/17/2001. These women were at least 12 months in amenorrhea and presented the results of a bone densitometry study performed at the Nuclear Medicine Department of HC/Unicamp. The following variables were evaluated: age, color, body mass index, level of education, smoking, use of medication, age at menopause, parity, use and length of hormone replacement therapy and its effect on bone mineral density. Statistical analyses were performed using logistic regression ajusted by age and hormone replacement therapy use. RESULTS: the mean age of the studied women was 53.9 years (± 7.1 SD) with mean age at menopause being 45.9 years (± 6.9 SD). Osteoporosis occurred in 14.7% and osteopenia in 38% of the cases in the lumbar vertebrae (L2-L4 interspace) and in 3.8 and 32.7% in the femur, respectively. Logistic regression adjusted to age and hormone therapy showed an association between the following variables: level of education, age at menopause and body mass index. CONCLUSION: there was a high prevalence of osteoporosis and osteopenia in the studied population. Advanced age, lower level of education, late menarche, early menopause and lower body mass index were identified as risk factors for developing decreased bone mass in the studied population.
