Assessing relationships between health-related quality of life and adherence to antiretroviral therapy.
OBJECTIVE
To investigate associations between health-related quality of life (HRQoL), as assessed using the multidimensional quality of life-HIV (MQOL-HIV) questionnaire, and adherence to antiretroviral treatment in HIV-infected subjects.


METHODS
Multicentre cross-sectional study in three institutional tertiary hospitals in northwest Spain.


METHODS
The MQOL-HIV was completed by 235 HIV-infected adults undergoing antiretroviral treatment. Adherence to antiretroviral therapy was assessed by using patient's self-report. Information about sociodemographic characteristics and clinical variables was also collected.


RESULTS
Good adherence (> or = 95% of prescribed pills correctly taken) was reported by 131 patients (55.7%). Univariate analyses indicated that the sociodemographic and clinical variables associated with adherence were age, educational level, income, employment, home stability, transmission route, history of previous antiretroviral therapy, and number of prescribed pills/day. Subscales of MQOL-HIV associated with adherence were mental health, cognitive functioning, financial status, medical care, partner intimacy, and (in men only) sexual functioning. Stepwise logistic regression showed that good adherence was more frequent in patients aged > 40 years (odds ratio, OR: 2.50; 95% confidence interval, CI: 1.15-5.61) and in patients with high cognitive functioning (OR: 2.26; 95% CI: 1.19-4.30). Conversely, poor adherence was more frequent in patients without stable home (OR: 2.96; 95% CI: 1.39-6.32), in patients required to take 14 or more pills/day (OR: 2.17; 95% CI: 1.18-4.28), in patients with low financial status (OR: 3.42; 95% CI: 1.57-7.45), and in patients reporting low medical care (OR: 2.07; 95% CI: 1.07-3.98).


CONCLUSIONS
HRQoL dimensions, notably cognitive functioning, financial status and medical care, are closely associated with antiretroviral therapy adherence.
