Abstract

Objective: To evaluate the possible association between hyperuricemia and cardiorespiratory fitness levels/nutritional profile, grouped into a single variable, in schoolchildren. Method: Cross-sectional study of 2335 students from Elementary schools, aged 7-17 years of both genders, stratified by conglomerates of a municipality in Southern Brazil. Body mass index (BMI) was calculated and cardiorespiratory fitness (CRF) was assessed by the 6-minute run/walk test. The BMI and CRF were grouped into a single variable, considering: (1) low and normal weight/fit; (2) low and normal weight/unfit; (3) overweight-obesity/fit; (4) overweightobesity/unfit. The Poisson regression (prevalence ratio, PR) was used for the association between hyperuricemia and BMI/CRF ratio with 95% confidence intervals and differences were considered significant when p 0.05. Results: There is an association, although subtle, between the presence of hyperuricemia withlow levels of CRF and the presence of excess weight, when grouped into a single variable. Boysand girls with this condition have higher prevalence of hyperuricemia (PR: 1.07; p = 0.007 forboys; PR: 1.10; p 0.001 for girls). Conclusion: Together, excess weight and low levels of cardiorespiratory fitness are associatedwith the presence of hyperuricemia in schoolchildren. (C) 2017 Sociedade Brasileira de Pediatria.
