Introduction. Due to the lack of information on blood pressure values in children and adolescents in our area, we established the following objectives: to measure the trends in blood pressure values according to gender, age, body mass index, height and socioeconomic status in schoolchildren from Corrientes. Population, material and methods. Between September 2004 and October 2005, a cross sectional study was performed in 2,507 schoolchildren of both genders, aged 10-15 years, in 7 urban schools of Corrientes, Argentina. Study variables were gender, age, weight, height socioeconomic status, and blood pressure. Results. 2,507 schoolchildren (1,373 girls and 1,134 boys) were studied. Mean values for each variable were: age: 12.9 ± 1.7 years; weight: 47.7 ± 1.7 kg, height: 1.54 ± 0.9 m; systolic blood pressure: 110 mm Hg ± 12.2 mm Hg, diastolic blood pressure: 70.0± 9.4 mm Hg, BMI: 19.8 ± 3.7. Conclusions. Though no overall differences were seen in blood pressure values between genders, when it was considered by age groups, a significant difference for systolic blood pressure was found for girls in the group of 10 to 12 years. On the contrary, in the group of 13 to 14 years, the difference was significant for males. Blood pressure increased concomitantly with age, body mass index, height and socioeconomic status.
