Summary: The school environment is privileged place to promote healthy habits of life and prevention of diseases. The objective of this study is to evaluate the effectiveness of a health intervention program on the pressure levels of schoolchildren in the public school system in Vitória / ES-Brazil. This is a intervention study conducted with 237 schoolchildren aged 6 to 12 from two public schools, randomly defined as Intervention and Control school. Anthropometric, hemodynamic data, 12 - hour urine at night, and data on the practice of physical activity and eating habits of schoolchildren were collected. All the students were evaluated at the beginning and at the end of the study and the participants of the Intervention group underwent educational actions that stimulated the promotion of healthy eating practices and physical activity. To test differences between groups, chi-square or Fisher's exact test was used for categorical variables, and Student's t-test or Mann-Whitney test for continuous variables. The paired t-test or Wilcoxon was used to evaluate differences between averages of continuous variables in paired samples. Correlation tests were performed to evaluate the relationship between variables at baseline. The rate of variation of systolic blood pressure (SBP) and diastolic blood pressure (DBP) throughout the follow-up, according to the allocation group, was evaluated using linear generalized models for time-repeated measures. There was a reduction in the means of SBP (0.5 mmHg) and DBP (0.6 mmHg) in the intervention group, and a statistically significant increase of SBP (1.8 mmHg) and DBP (2.2 mmHg) in the control group (p <0.05). Significant correlations were found between the DBP and the time of exposure to the screen (p <0.01) and the quality of school feeding (p <0.05) at baseline. In conclusion, the proposed intervention was effective for prevent the increase in BP in the studied group, being feasible to be reproduced in a school environment.
