RESUMO

Adherence to treatment represents a worldwide problem, due to the outcome chronic diseases, increasing in mortality and health systems costs. In Brazil, the magnitude of non-adherence to antihypertensives is not well-known. This thesis aims to find out the prevalence and risk factors associated to non-adherence to antihypertensive treatment among people with hypertension assisted by family health program in Blumenau, SC. Its a sectional epidemiological study with 595 persons provided by stratified sample procedure. Users of family health services were visited at home and a tested questionnaire (QAM-Q) was used to measure non-adherence and other variables (related to social, economical, demographics, health assistance and medicines) in an private interview. Descriptive analysis was presented with 95% confidence interval, and odds ratio was calculated to measure association. Variables with p-value <0.10 were included in mulvariated analysis. Non-conditional logistic regression model with a hierarchical approach was used to fit odds ratio for confounding, with a p-value <0.05. Most of people are females (70.4%) average age between 60.6 years, whites (80.7%), married (63.6%), studied 4 years or less (64.3%), unemployed (75.5%). 13.1% are smokers and 23.7% drink alcohol beverages. The average time of medicine use was of 127.9 months, on average 1,9 medicines. Monotherapy with IECA is the most frequent scheme (19.1%) and 20.1% told adverse reactions. Diabetes mellitus (44.8%) and lipid disorders (24.7%) were the most frequent associated disease and common mental disorders present in 44.8% of people. The majority of people seemed satisfied with the health services. The prevalence of nonadherence to antihypertensives was 53% and 69.3% have blood pressure higher than 140x90mmHg. People of C/D/E classes(OR=1.7; IC95% 1.1-2.4), employed workers (OR=1.6; IC95% 1.1-2.4), specially unqualified ones (OR=3.2; IC95% 1.8-5.8), are in conditions associated with non-adherence. Among the variables related to health services, the need to buy medicines (OR 4.5; IC95% 1.4-14.0) and more than 6 month since last appointment (OR=1.6; IC95% 1.0-2.5) are also associated to non-adherence. Previously stopping the treatment (OR=1.8; IC95% 1.2-2.7), to have treated less than 3 years (OR=1.3; IC95% 1.2-2.7) and the presence of common mental disorders (OR=2.1 IC95% 1.4-2.9) represent people and treatment characteristics associated to antihypertensives nonadherence. The study of determinants of non-adherence, articulated in an theoretic hierarchical model, which ordinate the variables in blocks, allowed to highlight the importance of socioeconomic factors to explain non-adherence. A better discrimination of socioeconomic variables was obtained using a theoretical approach and hierarchical logistic model. It shows that social inequalities can be directly associated to non-adherence or mediated through factors of services and people
