[Impact of hormone replacement therapy on body weight].
OBJECTIVE
to evaluate the effect of hormone replacement therapy (HT) on the weight on perimenopausal women as well as the effect of different treatment regimens on this parameter.


METHODS
a retrospective study of 139 women with menopause for less than 2 years, who were monitored with periodical visits in our department. We compared two groups: women who started HT (n=89) with women who had no hormonal treatment (n=50) and in the two groups, we evaluated the changes in body weight over a 1-year period. In the first group, we assessed the same parameter as a function of different treatment regimens: estrogen alone versus estrogen combined with progestin and standard dose versus low dose. The SPSS® program was used for statistical analysis, with the level of significance set at p<0.05.


RESULTS
the groups were similar with respect to demographic and baseline characteristics; weight gain was higher in the untreated group (434 vs 76 g), but the difference observed was not significant (p = 0.406); among HT users, those taking estrogen alone had an increased weight gain compared to women taking estrogen with progestin (775 vs 24 g), although no statistically significant difference was observed and the same applied when comparing the dose initially prescribed (92 vs 49 g).


CONCLUSIONS
despite the common belief about weight gain associated with HT, the results of the present study seem to contradict this point, with no additional weight gain beyond that normally associated with this period in a woman's life.
