Occurrence of metabolic risk in schoolchildren using a noninvasive indicator: waist and height ratio.

Introduction: Metabolic disorders in childhood and adolescence have been increasing considerably. Thus, the importance of performing an early diagnosis is emphasized. Objective: To analyse the occurrence of metabolic risk using a non-invasive marker in schoolchildren. Methods: This is a descriptive study with a quantitative approach, with random sample of 174 schoolchildren (70 boys and 104 girls) from 10 state high schools in the city of Passo Fundo, Rio Grande do Sul, Brazil. The height (cm) was verified according to the procedures of the Brazilian Sport Project and the waist circumference (cm) was measured with a flexible and inelastic tape measure. From this the waist-to-height ratio was calculated, which takes into account the proportion of abdominal fat by the individual’s height, considering the cut-off point of Ashwell & Hsieh. For data analysis we used descriptive and chi-square statistics. Results: The metabolic risk of schoolchildren was 13.8%, when stratified by sex, the occurrences were 11.4% for males and 15.4% for females, but there was no significant difference between the sexes (X² = 0.54; p= 0.45). Conclusion: The use of non-invasive markers for the diagnosis of metabolic risk indicated a high occurrence of it in schoolchildren, with the girls presenting a higher risk. The use of this method is important because it allows the evaluation of a greater number of schoolchildren and the early identification of health risk. In addition to being a low-cost, easy-to-apply method. [ABSTRACT FROM AUTHOR]
