Isoniazid Preventive Therapy Adherence and Associated Factors among HIV Positive Patients in Addis Ababa, Ethiopia

Abstract EN

Tuberculosis coinfected with HIV constitutes a large proportion of patients in Ethiopia.

Isoniazid preventive therapy (IPT) is recommended for the treatment of latent tuberculosis infection.

However, the level of IPT adherence and associated factors among people living with HIV (PLHIV) have not been well explored.

This study aimed to assess adherence to IPT and associated factors among PLHIV in Addis Ababa.

Facility based cross-sectional study was conducted.

The study was conducted in 10 health centers and 2 hospitals.

Patients were consecutively recruited till the required sample size was obtained.

From 406 PLHIV approached, a total of 381 patients on IPT were interviewed.

Data were entered and analyzed using Epi-Info version 3.5 and SPSS version 16.

The level of adherence to IPT was 89.5%.

Patients who have taken isoniazid for ≥5 months were more likely to be adherent than those who took it for 1-2 months [AOR (95%CI) = 5.09 (1.41–18.36)].

Patients whose friends decide for them to start IPT were less likely to be adherent than others [AOR (95%CI) = 0.10 (0.01–0.82)].

The level of adherence to IPT in PLHIV was high.

Counseling of patients who are in their first two months of therapy should be more strengthened.

Strong Information Education Communication is essential to further enhance adherence.
