Resumo
Verificar os efeitos da terapia hormonal (TH) sobre o equilíbrio postural em mulheres na pós-menopausa e sua associação com o risco de quedas. Realizou-se estudo transversal com 225 mulheres, idade 45-75 anos, atendidas em Hospital Universitário. As participantes foram divididas em dois grupos: usuárias de TH (n=102) e não usuárias (controle, n=123). Incluíram-se mulheres com amenorréia >12 meses e idade ≥ 45 anos. E se excluíram aquelas com doenças neurológicas ou musculoesqueléticas, história atual de vestibulopatias, déficit visual sem correção, obesidade grau III, usuárias de drogas que alterem o equilíbrio. Consideraram-se usuárias de TH aquelas que faziam uso contínuo há pelo menos seis meses. Foram analisados o histórico de quedas (últimos 24 meses) e as características clínicas e antropométricas. O equilíbrio postural foi avaliado pela estabilometria (plataforma de força), pelo teste de Romberg, pelo alcance funcional e teste do agachamento. Para análise estatística foram empregados o Teste da Mediana, o teste do Qui-Quadrado, regressão logística no risco para queda (odds ratio-OR) e o coeficiente de correlação de Spearman. As mulheres usuárias de TH eram mais jovens (53,0 anos vs 57 anos) e de menor tempo de menopausa (5,5 anos vs 10,0 anos) quando comparadas as não usuárias (p<0,05), sem diferenças antropométricas. A frequência de quedas foi significativamente menor entre as usuárias de TH quando comparadas as não usuárias, 51 vs 88 quedas, respectivamente (p<0,05), que apresentaram risco ajustado de 0,49 (IC 95% 0,27-0,88) vez menor para quedas que o grupo de não usuárias. Nos parâmetros estabilométricos, as usuárias de TH apresentaram significantemente menor amplitude de deslocamento latero-lateral e ântero-posterior e menor área de deslocamento quando comparadas as não usuárias (p<0,05). No teste de Romberg notou-se aumento...
To analyze the effects of hormone therapy (HT) on postural balance in postmenopausal women and its association with risk for falls. A crosssectional study was conducted on 225 women aged 45-75 years and cared for at the outpatient clinic of a University Hospital. The participants were divided into two groups: HT users (n=102) and non-users (control, n=123). Women in amenorrhea >12 months and age ≥ 45 years were included. Those with neurological or musculoskeletal disorders, current history of vestibulopathies, uncorrected visual deficit, level-III obesity or drug use that could affect balance were excluded. Women utilizing continuous HT for at least 6 months were considered to be HT users. Histories of falls (last 24 months) as well as clinical and anthropometric characteristics were analyzed. Postural balance was assessed by stabilometry (computerized force platform), Romberg’s test, functional reach test and the crouching test. For statistical analysis were used: the Median test, the Chi-square test, the logistic regression method (odds ratio- OR) for fall risk, and Spearman’s correlation coefficient. Women users of HT were younger (53.0 years vs. 57 years) and had been menopausal for a shorter period of time (5.5 years vs. 10.0 years) as compared to non-users (p<0.05); no anthropometric differences were observed. The frequency of falls was significantly lower among HT users as compared to non-users, 51 vs. 88 falls, respectively (p<0.05), that presented an adjusted risk of 0.49 (CI 95% 0.27-0.88) time lower of falls than the non-users group. With respect to the stabilometric parameters, HT users showed significantly lower amplitude in latero-lateral and antero-posterior oscillation and a smaller oscillation area as compared to non-users (p<0.05). Romberg’s test showed progressive positive increase as the test difficulty increased; however, significant differences were... (Complete abstract click electronic access below)
