Resumo
Avaliar a associação entre o equilíbrio postural e a densidade mineral óssea (DMO) em mulheres na pós-menopausa e correlacionar com o risco de quedas. Realizou-se estudo de corte transversal com 225 mulheres, idade 45-75 anos, atendidas em Hospital Universitário. Incluíram-se mulheres em amenorréia >12 meses e idade ≥ 45 anos, com valores de DMO (coluna lombar e colo de fêmur) pelo DXA, dos últimos 12 meses. E se excluíram aquelas com doenças neurológicas ou musculoesqueléticas, história atual de vestibulopatias, déficit visual sem correção, obesidade grau III e usuárias de drogas que alterem o equilíbrio. As mulheres foram divididas segundo a DMO em > -2,0 DP (n=140) e ≤ -2 DP (n=85). 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), teste de Romberg, alcance funcional e teste do agachamento. Para análise estatística foram empregados o Teste de Wilcoxon para variáveis quantitativas, o teste do Qui-Quadrado ou Exato de Fisher para variáveis categóricas e o método de regressão logística para o risco de quedas (Odds Ratio-OR). As pacientes com DMO > -2,0 DP eram mais jovens e com menor tempo de menopausa, assim como apresentavam maior IMC e circunferência da cintura quando comparadas aquelas com baixa DMO (≤ -2 DP) (p<0,05). Observou-se que 57,8% (130/225) das participantes relataram episódio de queda nos últimos dois anos, sem diferença significativa na distribuição percentual entre os grupos (p=0,055). Nos parâmetros estabilométricos e no alcance funcional não foram demonstradas diferenças na comparação entre os grupos (p>0,05). No teste de Romberg notou-se aumento progressivo da positividade à medida que aumentava a dificuldade do teste, sendo observada diferença significante entre os grupos apenas com...
To analyze the association between postural balance and bone mineral density (BMD) in postmenopausal women and correlate it with risk for falls. A cross-sectional study was conducted on 225 women aged 45-75 years and cared for at a University Hospital. Women in amenorrhea >12 months and age ≥ 45 years, with BMD values (lumbar spine and femur neck) by DXA for the last 12 months, 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. The women were divided, according to BMD, in > -2.0 DP (n=140) and ≤ -2 DP (n=85). Histories of falls (last 24 months) as well as clinical and anthropometric characteristics were evaluated. Postural balance was assessed by stabilometry (strength platform), Romberg’s test, functional reach test and the crouching test. For statistical analysis, Wilcoxon’s test was used for quantitative variables, the Chi-square or Fisher’s exact test for categorical variables and the logistic regression method for fall risk (Odds Ratio-OR). Patients with BMD > -2.0 DP were younger and had been menopausal for a shorter period of time; they also showed higher BMI and larger waist circumference as compared to those with low BMD (≤ -2 DP) (p<0.05). It was observed that 57.8% (130/225) of the participants reported fall episodes in the last two years, without significant difference in the percent distribution between the groups (p=0.055). No differences were found in the comparison between the groups (p>0.05) for stabilometric parameters or functional reach test. Concerning Romberg’s test, progressive positive increase was observed as the test difficulty increased, and significant difference between the groups was found only when the women kept their feet in a series and their eyes closed (p<0.05).
