RESUMO
OBJECTIVE: To evaluate the bone mass condition in the different types of menopause and know if there is difference between the groups. DESIGN: Case reports. MATERIAL AND METHODS: From September through November 2001 at the Specialties Hospital No. 1, we studied 184 patients with menopause. They were divided in 5 groups: 74 regular menopause, 31 surgical menopause and oophorectomy unilateral, 43 surgical menopause and bilateral oophorectomy, 32 premature menopause, and 4 post-radiotherapy menopause, analyzing the bone mass with a densitometry. The statistical analysis was by descriptive statistics and t student to find the difference between the groups. RESULTS: We observed 45% with osteopenia y 8% with osteoporosis in regular menopause. In surgical menopause and oophorectomy unilateral group, we found 26% with osteopenia and 6% with osteoporosis. There were 42% with ostepenia and 14% with osteopososis in surgical menopause and bilateral oophorectomy group. In premature menopause, we found 47% with osteopenia and 12% with osteoporosis. In post-radiotherapy menopause, we found 75% with osteopenia and 25% with osteoporosis. All of them with predominance in femur. We did not observe any significant difference between the surgical and the premature menopause groups. CONCLUSIONS: In a half of patients with menopause we found bone mass decrease with predominance in femur, like osteopenia. There was no significant difference between the surgical and the premature menopause groups.
