Introdução: A obesidade está fortemente associada com a morbidade e mortalidade, no entanto sabe-se menos sobre o seu impacto na qualidade de vida relacionada com a Saúde (QVRS). Pretendeu-se assim avaliar a qualidade de vida relacionada com a Saúde em utentes antes e após a perda ponderal e aferir a relação desta com a perda ponderal e estado nutricional. Metodologia: Estudo analítico longitudinal com intervenção nutricional para perda de excesso ponderal, com uma amostra de 49 utentes. A recolha de dados para caracterização do estado nutricional realizou-se na primeira consulta de excesso ponderal, repetindo-se após 8 semanas. Os dados referentes à QVRS foram recolhidos a partir da utilização dos questionários SF-36v2 e EQ-5D- 3L. Resultados: A amostra, na sua maioria do género feminino, apresentava uma idade média de 39 anos, peso de 83,9Kg, índice de massa corporal de 30,8Kg/m2, massa gorda de 37,80%, perímetro da cintura de 101,83cm e razão de cintura/altura de 0,61cm. No final da intervenção observou-se uma diminuição de 4,3% do peso e em todas as medidas antropométricas e um aumento significativo na QVRS, nomeadamente na escala EQ-VAS, no índice EQ-5D-3L e nas dimensões função física, saúde geral, vitalidade e medida sumária física do SF-36. O peso, a massa gorda e o índice de massa corporal encontraram-se negativamente associadas a pelo menos uma das dimensões avaliadas e verificou-se uma correlação positiva entre o índice EQ- 5D-3L e a redução do peso, índice de massa corporal e massa gorda. Conclusão: Um pior estado nutricional influencia negativamente a QVRS, sendo que a redução ponderal está associada ao seu aumento (EQ-5D-3L). Concluiu-se que uma redução ponderal de apenas 4,3% foi suficiente para alterar positivamente QVRS.
ABSTRACT - Introduction: Obesity is strongly associated with morbidity and mortality, but the impact on health-related quality of life is less known. The aim of the study was to evaluate the health-related quality of life (HRQOL), before and after the loss weight ratio and to assess its relationship with weight loss and nutritional status. Methods: Longitudinal analytical study with nutritional intervention for loss of overweight, with a sample of 49 patients. The data collection was performed at the first nutritional appointment of excess weight and it was repeated after 8 weeks. Data related to HRQOL were collected using the SF- 36v2 and EQ-5D-3L questionnaires. Results: The sample, mostly of female genre, had an average age of 39 years, a weight of 83.9kg, a body mass index of 30.8 kg/m2, fat mass of 37.80%, a waist circumference of 101.83cm and the waist-to-height ratio of 0.61cm. At the end of intervention there was a reduction of 4,3% of the weight and in all anthropometric measurements and a significant increase in HRQOL, particularly the EQ-VAS scale, the EQ-5D-3L index, and physical function, general health, vitality and physical summary of SF-36. The weight, fat mass, and body mass index were negatively associated with at least one of the dimensions evaluated, as well as that there was a positive correlation between weight reduction, body mass index and fat mass with the EQ- 5D-31. Conclusion: It was also verified that a worse nutritional status negatively influences the Health-related quality of life and that weight reduction is associated with its increase. It was concluded that a weight reduction of only 4.3% was enough to positively change the quality of Health-related quality of life.
