The reports will be of prevalence (cross-sectional) and incidence (cohort). To evaluate the significance between the groups of blood pressure depending on morbidities and other variables, it is used a generalized linear model by adjusting the effect of the response variable based on the age, gender and tension group in all cases. In some cases, and when the response variable requires it, it is added the body mass index (BMI). When the response variable is qualitative, it is used a logit link function and it is obtained the corresponding Odds ratio with confidence intervals to 95%; while if the variable is quantitative it is used the identity function. Finally, the multiple comparison test of Tukey-Kramer is made in order to compare the groups of tension with a significance level of 0.05.
