RESUMO

Introduction: Balance disorder has great impact on the lives of the elderly, causing instability, often disabling, movement restriction and predisposition to falls and fractures. These factors may lead to increased morbimortality, decreased independence and costly treatments, hospitalizations and special care imposed on families and society. Objective: This study aims to analyze the prevalence of alterations in body balance and investigates the characteristics (demographic, health, anthropometric and lifestyle issues) and factors related to balance disorder as well as its association with self-reported presence of dizziness/vertigo. It also investigates the influence of balance in adverse clinical outcomes and estimates the incidence rate in the 2006-2010 period. Methods: This epidemiological cross-sectional population-based research, developed under SABE Study in São Paulo, evaluated the elderly who undertook the Balance Test in 2006. The data were analyzed descriptively and according to multiple and simple linear logistic regression models. Results: From a total of 1,226 elderly individuals evaluated, 83.7 per cent achieved the highest score on the test. Factors such as age, fracture history, difficulty in at least one mobility, cognitive decline and fall episode in the previous year had major influence on the balance performance and associations were statistically significant (p<0.05). Physical activity and use of calcium channel blockers were identified as factors that improved thperformance on the test. An increase by one point in the Balance Test reduces by 27 per cent the chances of the individual having been hospitalized in the previous year. Conclusion: Among the elderly, objective measures of performance on the Balance Test were higher than self-reported incidence of dizziness or vertigo and can provide information on functional status that is not obtained from self-reported measures. Balance measures proved to be predictive of hospitalization elderly individuals who have better balance are less likely to be hospitalized
