Avaliação da composição corporal e taxa metabólica basal em mulheres no Menacme e na pós menopausa em policlínica em João Pessoa - PB.

Abstract

The reproductive life of women is marked by different phases. The morphological and metabolical changes of the female body are influenced by both hormonal decline as aging itself, occurring progressive reduction of daily energy expenditure and basal metabolic rate, resulting in a change in body composition; this can be measured by bioelectrical impedance. The objectives of this study were to evaluate the influence of hormone on body composition and reduction in BMR (Basal Metabolic Rate), and the correlation between the variables of body composition and BMR of patients seen in a clinic in the city of João Pessoa. Data were obtained through In Body ® bioelectrical impedance, using the inferential statistics for data analysis. The study included 18 patients who were postmenopausal and 73 premenopausal. The BMR was not dependent on hormone levels presented by participants. The WHR (Waist to hip Ratio) and BMR were correlated and exerted influence over each other when related to the reproductive period. There was a statistically significant relationship between WHR and BMR, however BMI (Body Mass Index) and percentual fat were independent of hormone levels. Fat mass and lean mass were not associated with premenopausal patients, while fat mass was high in menopausal women and the lean mass did not decrease as expected. The only variables that did not have a statistically significant correlation with BMR were WHR and fat mass. We concluded from our results that the body composition of premenopausal women have suffered more interference of lifestyle rather than the own female hormone physiology. This, it is necessary to perform further studies to corroborate the findings of this article and to identify modifiable factors that may affect the quality of life of these patients.
