DYNAMIC POSTURAL BALANCE IS MEDIATED BY ANTHROPOMETRY AND BODY COMPOSITION IN OLDER WOMEN.

To investigate the relationship between anthropometry and body composition with dynamic postural balance in elderly women with low bone mineral density (BMD). 45 older women (≥ 60 years), low BMD and nutritional diagnosis of low weight to overweight. For the assessment of body composition, Dual energy X-ray emission densitometry and anthropometric examination were used to measure: body mass (kg), height (cm) and BMI (k/m There was a negative correlation between miniBESTest (r = - 0.566; p ≤ 0.001) and time to ascend and descend step (r = - 0.393; p ≤ 0.007) with fat mass, and positive correlation with miniBESTest (r = 0.526; p ≤0.001) and time to go up and down a step with muscle mass (r = 0.297; p ≤ 0.04). As for anthropometric variables, only height showed a positive correlation (r = 0.296; p ≤ 0.04) with the speed in the sit and stand test. Lean mass reduces postural oscillations; in contrast, fat mass negatively interfered with dynamic postural balance in women with low BMD. Height was related to dynamic postural balance, the taller the elderly, the worse their balance. Investigar a relação da antropometria e composição corporal com o equilíbrio postural dinâmico em idosas com baixa Densidade Mineral Óssea (DMO). 45 idosas (≥ 60 anos), baixa DMO e diagnóstico nutricional entre baixo peso e sobrepeso. Para a avaliação da composição corporal utilizou-se a densitometria por emissão de raios x de dupla energia e exame antropométrico para aferir: massa corporal (kg), estatura (cm) e índice de massa corporal (IMC) (k/m2). A avaliação do equilíbrio postural dinâmico foi realizada pelo teste clínico mini Balance Master Evaluation System, pelo teste computadorizado Balance Master A massa magra reduz as oscilações posturais. Em contrapartida, a massa gorda interfere de forma negativa no equilíbrio postural dinâmico de mulheres com baixa DMO. A estatura esteve relacionada ao equilíbrio postural dinâmico: quanto mais altas as idosas pior era seu equilíbrio.
