Antiretroviral Treatment Adherence among People Living with HIV in Taipei, Taiwan.

Introduction: Adherence to Highly Active Antiretroviral Therapy (HAART) is critical in controlling HIV. Poor medication adherence may lead to higher disease mortality, increased HIV spread, and transmission of drug-resistant strains. Identifying the specific factors that contribute to suboptimal medication adherence in people with HIV is crucial for developing effective, personalized interventions.

Methods: This study conducted a cross-sectional analysis by enrolling individuals over 18 years of age with HIV at a single clinic in Taipei, Taiwan, from December 2018 to November 2020. Participants completed a questionnaire that collected demographic data, recreational drug use, comorbidities, and history of sexually transmitted infections (STIs). The Medication Adherence Report Scale (MARS-5) was utilized to assess treatment adherence. A multiple logistic regression model was applied to identify the factors influencing adherence.

Results: A total of 831 PWH were included in the analysis. After controlling for demographics, comorbidities, and recreational drug use, independent risk factors associated with poor adherence among PWH include the presence of a depressive disorder (AOR:2·887, 95% CI:1·461-5·703, p = 0·002), a history of acquired gonorrhea (AOR:2·026, 95% CI:1·079 - 3·803, p = 0·028), methamphetamine use within past three months (AOR:2·073, 95% CI:1·172-3·665, p = 0·012), HIV-1 RNA ≥ 40 copies/ml (AOR:5·221, 95% CI:2·976-9·157, p < 0·001) and younger age (AOR:0·959, 95% CI:0·932-0·988, p = 0·006).

Conclusions: To enhance HIV treatment adherence, targeted efforts are essential for PWH who are young, have used methamphetamine in the past three months, are experiencing depressive disorders, or have previously acquired gonorrhea.
