RESUMO
OBJECTIVE: To objectively analyze vaginal dryness in postmenopausal women. METHODS: Forty healthy postmenopausal women, were divided in three groups according to the treatment they received. Group I, conjugated equine estrogens (CEE) 0.625 mg/day (n=20), group II, CEE 0.625 mg/day plus chlormadinone 1 mg/day (n=13), and group III, CEE 0.625 mg/day plus medroxyprogesterone 2.5 mg/day (n=7). Vaginal dryness intensity was analyzed using an analog visual scale, and vaginal humidity measuring the moistening in mm of a pH test strip. Both were evaluated at baseline and 3 months after the beginning of treatment. The comparison among groups and between the baseline and final results was done with Student's t-test for paired and independent samples, respectively. Pearson correlation analysis was carried out between final vaginal dryness intensity and the final moistening of the pH test strip. RESULTS: No statistically significant differences were found in age neither in somatometric variables among the groups. In the three groups, vaginal dryness intensity significantly decreased and the pH test strip moistening significantly increased. A significant negative correlation was only found in group II (-0.690 P<0.009). CONCLUSIONS: Vaginal dryness evaluation assessing the pH test strip moistening is an objective method to evaluate this symptom in postmenopausal women, and the results are independent of the hormone replacement therapy schedule.
