Sex differences in adherence to antihypertensive treatment in patients aged above 55: The French League Against Hypertension Survey (FLAHS).


ABSTRACT: Despite the availability of efficient therapies to reduce the risk of cardiovascular complications, poor adherence to antihypertensive (anti-HTN) drugs is frequent, especially during the first year of treatment and among uncontrolled/resistant hypertensive patients. The aim of the study was to identify factors associated with adherence to anti-HTN treatment and to examine whether they differ across sex. A total of 2743 treated hypertensive participants to the cross-sectional Metascope survey (France, 2015) aged 55 years or more were included. The authors measured adherence to anti-HTN treatment using the 6-item Girerd compliance test. Variations in adherence were examined using the Rao-Scott statistics and Poisson regression. Overall, 63.6% of participants were adherent to anti-HTN treatment. Adherence was more frequent among women than men (69% vs 58%, P < 10-4 ). For both sexes, level of adherence was positively associated with age (P < 10-4 ), but inversely associated with number of anti-HTN tablets, number of tablets taken for metabolic diseases, history of cardiovascular diseases, number of other chronic diseases (all P < 10-4 ). The inverse relationship between adherence and the number of anti-HTN tablets significantly differed between sexes (P < 10-4 ): Adherence decreased sharply when taking two or more anti-HTN tablets in men, whereas the decrease in women was only observed when taking three or more anti-HTN tablets. This study suggests that adherence to anti-HTN treatment is higher among women, decreases with the number of tablets prescribed, and differentially so across sex. Reducing the number of tablets for anti-HTN treatment may improve adherence, especially among men and patients with multiple comorbidities.
