Abstract

Background: Ethnic diversity is increasingly encountered in the HIV-infected population in North America, and it is unknown if beliefs surrounding illness and treatment vary among different ethnic groups.

Objective: Our objectives were to determine whether self-reported adherence, illness perceptions and treatment beliefs regarding HIV differ based on ethnicity.

Setting: This study was conducted during outpatient HIV clinic visits between March 1, 2010 and April 30, 2010 at two hospital-based clinics in Edmonton, AB, Canada.

Methods: A cross-sectional sample of 65 patients on antiretroviral therapy (34 Caucasian, 23 Aboriginal, and 8 from other ethnic groups) attending hospital-based clinics completed a self-administered survey; medical records were reviewed for demographic and treatment information.

Main outcome measure: An ANOVA with covariates was performed to measure variation of beliefs and adherence between ethnic groups.

Results: Mean self-reported adherence in the past week and past month was high (96 %) and the majority of patients (78.5 %) had a viral load <40 copies/mL. Patients had high perceived necessity scores and a low degree of perceived concern with antiretroviral therapy. In our study, treatment beliefs, illness perceptions, and self-reported adherence did not vary between ethnicities (p > 0.05).

Conclusion: Treatment beliefs, illness perceptions, and adherence appear to be largely similar in English-speaking patients with diverse ethnic backgrounds who have been on treatment for at least 3 months. Strong supports may overcome any cultural differences in treatment beliefs that were expected at the outset.
