ABSTRACT

Background: In 2012 prevalence of high blood pressure in Mexico was of 31.5%. Its treatment causes high costs due to the growing request of care to chronic-degenerative problems.
Objective: To determine percentage of both: positive and negative adherence to treatment, and to measure the strength of association between variables, to define risk ratio in patient adherence to treatment.
Material and method: A descriptive study by direct survey. The variables included: age, sex, illiteracy, clock interpretation, level of education, current diagnoses, time of evolution of the disease (‹1 year or ›1 year), if the patient knew the name of the medications, if the patient mentioned their medications correctly, if the patient was interested in learning the name of the medicines, complexity of the drug name (patient’s perception), the test of Morisky-Green-Levine, the question: If the drugs had a simpler name or a distinctive legend, would you know them?” and if the patient was with blood pressure in control or not. It was determined the percentage of positive and negative adherence to treatment. The statistical test was X2 for the qualitative variables and in all cases the value of statistical significance was 5% (p ‹ 0.05) and a confidence limit ›1 (for odds ratio and risk ratio). It was measure the strength of association between variables with odds ratio and risk ratio.
Results: The adherence to treatment was 26.5% meanwhile the negative adherence to treatment was 73.4%. Of the variables studied “Not knowing the name of the drugs in the treatment” represented statistical significance with a risk ratio 1.19 (IC ≥ 1), odds ratio 1.83 (IC ≥ 1) and a p value ›0.05. All of the other variables didn’t had statistical significance.
Conclusion: The negative adherence to treatment has a high prevalence in rural populations. Ignoring the name of the drugs used in treatment is a risk factor for a negative adherence to treatment.
