A qualidade de vida nos diferentes graus de obesidade

Abstract

BACKGROUND: Obesity is a multifactor disease with increasing prevalence of epidemic proportions and is a major public health problem of modern society. The assessment of quality of life (QL) has been increasingly used in healthcare; one of the most widely used instruments is the SF-36. It is a multidimensional questionnaire with 36 items comprised in eight domains: physical functioning, physical functioning, pain, general health, and vitality, social, emotional and mental health. OBJECTIVES: To evaluate and compare the quality of life among the different degrees of obesity and normal weight people. MATERIALS AND METHODS: We studied 120 subjects of both sexes, divided into four groups with 30 individuals each, according to the degree of obesity: G1 (BMI 30 to 34.9 kg / m²), G2 (BMI 35-39), G3 (BMI> 40) and G4 (BMI between 18.5 and 24.99). QOL was assessed using the SF-36. Statistical analysis consisted of mean, standard deviation, Kolmogorov-Smirnov and Shapiro-Wilk Levene test, ANOVA and comparison among groups Kruskal-Wallis. RESULTS: There was significant correlation between all variables. QL decreased with the increase of obesity and especially compared to the eutrophic group. CONCLUSION: Quality of life was inversely proportional to the degree of obesity, in other words the higher the degree of obesity, the worse the quality of their lives.
