Influência do excesso de peso sobre o equilíbrio postural e a mobilidade de candidatos à cirurgia bariátrica

Abstract

Abstract Obesity is considered a risk factor to health and besides generating metabolic and cardiovascular alterations, it is related to mechanical complications. Since stability may be altered due to anthropometric and biomechanical factors, studies investigating the relationship of excess weight on the mobility and balance of obese adults are still scarce. The research aimed to evaluate the postural balance and mobility of obese individuals who are waiting for bariatric surgery. This is a cross-sectional and descriptive study, conducted at the Hospital das Clínicas of the Universidade Federal de Pernambuco. The sample consisted of 97 individuals, 81 women, 16 men, age 38.39 ± 10.60 years and body mass index 47.5 ± 6.9 kg/m2. The Timed Up and Go test, which evaluates the mobility, resulted in 7.6 ± 1.7 seconds as the average of the longest times spent to perform the test. Regarding the evaluation of dynamic balance and mobility, it was found that the domains of anticipatory postural adjustments, necessary to prevent postural disturbances (median 5, 95%CI 5-6) and the domain of dynamic movement, which corresponds to the balance necessary to walk (median 8, 95%CI 7-9) are the most impaired in the subjects with obesity. Positive correlations were found between weight and dynamic balance. The findings indicate that excess body fat interferes with dynamic balance.
