Abstract

Objective

To investigate the association of blood pressure and body mass index, waist circumference, waist-to-height ratio and triceps skinfold, in children and adolescents in Curitiba, state of Paraná, Brazil.

Methods

Cross-sectional study with a random sample of 1,441 students from public schools, aged from10 to 16 years (655 boys and 786 girls). The following indicators were assessed: weight, height, waist circumference, triceps skinfold, systolic and diastolic blood pressures, pubertal stage, and socioeconomic status. Pearson correlation tests and multivariate logistic regression were used, considering p < 0.05.

Results

We found weak correlations among all the anthropometric parameters and systolic and diastolic levels, with coefficients values ranging from 0.18 to 0.28 (p < 0.001). In multivariate analysis, only body mass index [odds ratio (OR) = 2.9; 95% confidence interval (95%CI) 1.9-4.5] and triceps skinfold (OR = 1.9; 95%CI 1.3-3.1) were found as predictors of high blood pressure, regardless of abdominal adiposity, sexual maturation and socioeconomic status.

Conclusion

Total body adiposity seems to be a better predictor of high blood pressure risk than abdominal fat in this population.

Resumo

Objetivo

Investigar a relação entre pressão arterial e índice de massa corporal, cir- cunferência abdominal, razão cintura/estatura e dobra cutânea tricipital em crianças e adolescentes.

Métodos

Estudo epidemiológico transversal, do qual participaram 1.441 escolares de 10 a 16 anos de idade (655 meninos e 786 meninas), selecionados por amostragem aleatória sistemática. Avaliaram-se a massa corporal, a estatura, a circunferência abdominal, a espessura da dobra cutânea tricipital, as pressões arteriais – sistólica e diastólica – o estágio maturacional e a classe econômica. Utilizaram-se os testes de correlação parcial de Pearson e a regressão logística multivariada, considerando-se p < 0,05.

Resultados

Todos os indicadores antropométricos demonstraram fracas correlações com os níveis sistólicos e diastólicos, com coeficientes (r) variando de 0,18 a 0,28 (p < 0,001). Na análise multivariada, os únicos preditores antropométricos associados ao risco de pressão arterial elevada foram o índice de massa corporal (OR = 2,9; IC 95%: 1,9-4,5) e a dobra cutânea tricipital (OR = 1,9; IC 95%: 1,3-3,1), independentes da adiposidade abdominal, maturação sexual e nível econômico.

Conclusão

Nesta faixa etária, a adiposidade corporal total parece ser melhor determi- nante do risco de elevação da pressão arterial do que a adiposidade abdominal.
