In the last decades the prevalence of hypertension has increased among children. Lack of diagnosis of the disease in this age group and hence the lack of treatment, can anticipate the appearance of damage to vital organs such as kidneys and heart and increase the chance of maintenance of high blood pressure in adulthood. It is known that the development of hypertension is related to several factors among which we can mention the excess weight. The objective of this study was to investigate the association between waist-height ratio, body mass index and waist circumference with blood pressure levels in children between two and five years. It is cross-sectional study on a household basis that evaluated 279 children aged between two and five years. Anthropometric indices were investigated (waist-height ratio, body mass index and waist circumference), sociodemographic characteristics (age, maternal age, maternal education, economic status) and outcomes systolic and diastolic blood pressure. Associations were estimated by multiple linear regression analysis and predictive capacity by the area under the ROC curve (Receiver- Operating Characteristic). The median age was 3.5 years (2.9 to 4.3). Observed prevalence of high blood pressure 21.5%, 69.2% ratio increased height-waist, 11.5% of overweight and 21.1% of increased waist circumference. Children with increased height-waist ratio or overweight had a higher prevalence of high blood pressure (p <0.05). The increase of one unit of height-waist ratio was associated with increased of 1.78 and 3,53mmHg in systolic and diastolic, respectively, while the one-unit increase in body mass index was associated with increase of 1,0mmHg systolic (p <0.05). Increased waist circumference was not associated with systolic and diastolic pressures. The waist-height ratio showed higher area under the ROC curve 0.70 (0.63-.078) followed by body mass index 0.62 (0.54-0.70)(p <0.05). We conclude that relationship height-waist ratio and body mass index showed positive associations with blood pressure levels of children aged between two and five years. These indices show good predictive ability for high blood pressure in these children.
