Qualidade de vida e síndrome metabólica em mulheres Brasileiras: Análise da correlação com a aptidão aeróbia e a força muscular

Abstract

The metabolic syndrome (MetS) is defined as the presence of at least three out of five cardiovascular risk factors: hiperglicemia, insulin resistance, abdominal obesity, dyslipidemia and elevated blood pressure. Subjects with MetS still present worse perception of quality of life (QL) and low physical fitness as compared with subjects without MetS. However, correlations between physical fitness and QL have not been investigated in subjects with MetS. The aim of the present study was to compare the QL, muscle strength and aerobic fitness, as well as to analyse the correlatation between the QL and physical fitness in women with and without MetS. Forty-nine women, 21 with MetS (33.5 ± 9.1 years) and 28 without MetS (32.3 ± 7.9 years) were studied. Perception of QL, physical fitness and muscle strength were evaluated by the Short Form Health Survey 36 (SF-36), the distance covered in the 6 minute walk test (6MWT), and the handgrip test, respectively. Women with MetS presented worse perception of QL, covered a lower distance during the 6MWT and exhibited lower relative muscle strength. Additionally there was a positive correlation of aerobic fitness with four domains of QL: functional capacity, limitation by physical aspect, pain and social aspects. Women with MetS present lower muscle strength and aerobic fitness, as well as lower QL scores for the general health state, functional capacity, body pain, limitation by emotional aspects, social aspects of functionality and limitation by physical aspects as compared with women without MetS.
