Four hundred and twenty patients on antihypertensive drugs were studied. The mean age of the patient was 60.6 ± 11.7 years (range 21-85 years). There were 206 (49%) males and 214 (51%) females. Most respondents were Yoruba (86%), married (77%), and had primary education (28%). Most (61%) were adherent to antihypertensive therapy. Nonadherence was higher in the younger age group, respondents with lower education, and rural dwellers [Table 1].
