Proportion and Determinants of Adherence to Antiretroviral Therapy among HIV Positive People Registered Under ART Center in South India.

BACKGROUND

Antiretroviral therapy (ART) significantly delays the progression from HIV to AIDS. Adherence to ART is the second strongest predictor of progression to AIDS and death, after CD4 count. A very high level of adherence (≥95%) is required for ART to be effective on a long term and to prevent the emergence of resistant viral strains and prevent comorbidities.

METHODS

A case series study was undertaken at an ART center for a period of 6 months. Non-probability purposive sampling was adapted to select HIV-positive subjects aged >15 years on ART for more than 6 months. A predesigned semi-structured questionnaire was used to obtain the data. Treatment compliance was assessed by self-reported 1-week recall method.

RESULTS

A total of 536 HIV-positive people were interviewed, among which 315 (58.8%) of them were males and 214 (39.9%) were females. Nearly two third of the participants (359, 67.0%) reported ≥95% adherence to treatment. Personal commitments (51, 28.8%) and working time inconvenience (42, 23.7%) were the common reasons for less adherence. On bivariate analysis, married people (OR: 1.586, CI: 1.097-2.292), participants residing in rural area (OR: 1.628, CI: 1.130-2.345), participants not having side effects of drugs (OR: 5.324, CI: 3.491-8.181), participants equipped with better knowledge about ART (OR: 2.019, CI: 1.377-2.961), and participants having support of friends and family members (OR: 1.612, CI: 1.019-2.540) showed a higher level of adherence to ART.

CONCLUSIONS

Demographic factors such as marital status, residing in rural area, and other personal factors like having good knowledge about ART, without side effects to drugs, and having support of friends and family members were found to show a high level of adherence to ART.
