Objective: to compare mammographic density changes, case by case, according to image digitization in three consecutive evaluations of users or nonusers of hormonal replacement therapy (HRT). Methods: 59 postmenopausal women were evaluated, 43 being users of cyclic or continuous estro-progestin hormonal replacement therapy, and 16 nonusers. The criteria of inclusion were: amenorrhea for at least 12 months, a normal mammographic examination at the beginning of the HRT (users) or the clinical follow-up without HRT (nonusers), at two incidences (mediolateral and craniocaudal). The following variables were used for the evaluation of mammary density: initial change - the difference between the first mammography after HRT performed in 12 ± 3 months and the mammography performed before HRT-and final change - the difference between the second mammography after HRT performed in 24 ± 3 months and the mammography performed before HRT. Wilcoxon and c² tests were used in order to evaluate the differences in mammographic density changes. Results: more than half (56.3%) of the women, HRT users with initial increase in mammographic density remained with the increase after the final evaluation. This finding was not significant (p=0.617). In the same group, the initial nonincrease was significantly associated with the final nonincrease (p=0.017). Among the nonusers, all breasts that were not totally fat at the initial evaluation presented a mammographic density decrease at the final evaluation. Conclusions: the majority of HRT users presenting mammographic density increase at the first evaluation, after approximately one year of use, remained with the increase at a second evaluation. After some time, the nonusers tended to present a significant mammographic density decrease (p=0.003).

Purpose: to evaluate the effects of hormone replacement therapy on the body mass index of postmenopausal women. Methods: for this purpose, 166 users and 136 non-users of hormone replacement were evaluated retrospectively during a period of three years. All women were assisted at the Menopause Outpatient Clinic of CAISM - UNICAMP, where the variations in this parameter were evaluated at the end of each year in relation to the initial parameters. The data analysis was performed through chi² test, Student's t test, and Mann-Whitney test. Results: we observed no significant variations in the body mass index, when comparing users and non-users during the three years of observation. Conclusion: hormone replacement therapy did not produce changes in this parameter in women properly assisted during its use.

PURPOSE: to identify factors associated with the occurrence of hot flashes in climacteric women living in Campinas, São Paulo. METHODS: data bank secondary analysis of a cross-sectional descriptive population-based study. The selection of 456 women aged 45-60 years was done through area cluster sampling. Data were collected via home interviews using structured, pre-tested questionnaires provided by the International Health Foundation/International Menopause Society and by the North American Menopause Society and adapted by the authors. The analyzed variables were age, race, use of contraceptive methods and hormonal therapy, tubal ligation, body mass index, menopausal status, time since menopause, hysterectomy, and cigarette smoking. Statistical analysis was performed using the mean, median and the prevalence ratio (PR). Multiple logistic regression was performed using the stepwise selection process with a 95% confidence interval (95% CI). RESULTS: bivariate analysis showed that postmenopausal women (PR: 1.42, CI 95%: 1.06-1.90) and those who were submitted to hysterectomy (PR: 1.50, CI 95%: 1.05-2.14) had a significantly greater chance of presenting hot flashes. After applying multiple regression analysis, there was no significant association between hot flashes and any of the evaluated variables. CONCLUSION: results were consistent with previous studies. Many doubts still exist about which factors are associated with hot flashes.

Purpose: to evaluate the effects of hormone replacement therapy (HRT) on the systolic and diastolic blood pressure of postmenopausal women. Methods: a total of 166 users and 136 non-users of hormone replacement were evaluated retrospectively during a period of three years. All women were assisted at the Menopause Outpatient Clinic of CAISM -- Unicamp, where the variations of these parameters were evaluated at the end of each year in relation to the initial parameters. The data analysis was performed through Student's t test, Mann-Whitney test, and the Wilcoxon nonparametric test. Results: we observed that the systolic blood pressure of HRT users was statistically lower at the end of the third year of use, compared to the initial values (p = 0.01). There was no significant difference in the diastolic blood pressure between users and non-users. Conclusion: hormone replacement therapy did not produce changes in the parameters studied in women properly assisted during the use of HRT.

Purpose: to compare bone mineral density (BMD) of postmenopausal women with and without the antecedent of tubal ligation, as well as to evaluate the associated factors that affect the bone mineral density of femur and lumbar spine of both groups. Methods: 70 postmenopausal women in each group were analyzed at CAISM-UNICAMP, during the year of 1998. All women answered a questionnaire about some clinical and reproductive characteristics and underwent bone densitometry (Lunar DPX) to measure bone mineral density of the femur and lumbar spine. Statistical analyses were performed using Student's t-test, Fisher`s exact test, Pearson c² test, Bonferroni`s test and multiple regression analysis. Results: mean age of patients was 53.2 years and for controls it was 52.6 years. Mean age of 48 years at menopause was similar in both groups. Mean age at tubal ligation surgery was 33.7 years and time since surgery was 18 years. The multiple comparison of the average bone mineral density of femur and lumbar spine did not show statistical differences between the groups. The percentage distribution of the T-score categories of femur and lumbar spine, classified into normal and altered, also did not show statistical differences between both groups. Multiple regression analysis showed that bone mineral density of femur was directly associated with body mass index, but age was indirectly associated. The variables dark skin, parity, age at menopause, educational level and body mass index were directly associated with bone mineral density of lumbar spine, but age at menarche was inversely associated. Conclusion: these findings suggest that tubal ligation does not seem to cause an additional reduction in bone mineral density when evaluated in postmenopause.

Purpose: to evaluate the percentage of 45- to 60-year-old women complaining of urinary incontinence, who look for medical treatment, and the factors possibly associated with the decision of visiting the doctor and the reasons for not doing so. Methods: a secondary analysis of a population-based survey on climacterium and menopause in women living in the city of Campinas, São Paulo state, was carried out through a descriptive, exploratory and cross-sectional population study. A total of 456 women between 45 and 60 years of age were selected through a sampling process. The age at menopause and its associated factors were evaluated, as well as the prevalence of climacteric symptoms, the use of medical care, self-perception of the health status, and the sociocultural, sociodemographic and socioeconomic characteristics. Urinary incontinence complaint and the search for medical help due to the presence of symptoms were explored. The data were collected through home interviews, using a structured and pretested questionnaire provided by the International Health Foundation/International Menopause Society and by the North American Menopause Society, and adapted by the authors. The statistical analysis was performed using Fisher's exact test. Results: thirty-five percent of the interviewees reported constant or intermittent stress incontinence, although only 59% of the patients with the complaint sought medical help. Conclusion: the majority of the women presenting urinary incontinence do not complain to the doctor if they are not questioned objectively.
