- Consistent individual effort in engagement in HIV medical services has been associated with positive health outcomes in people living with HIV (PLHIV). However, whether these benefits are facilitated by improved medication adherence has not been widely studied. This study aimed to investigate the marginal effect of engagement in HIV care on medication adherence at a public health facility in Kenya. Between February and April 2013, 392 patients on HIV care at Nyeri Provincial General Hospital participated in this study. Data were collected using a self-administered health survey questionnaire assessing health and sociodemographic statuses. A manual stepwise general linear model was specified to measure the effect of engagement in HIV and other associated predictors on medication adherence. Engagement in HIV care was significantly associated with log-transformed medication adherence in the sample (100 center dot beta = 9.2%, 95% CI 3.2-15.1) irrespective of gender and other selected predictors. Longer duration on antiretroviral therapy was also a significant predictor of better medication adherence (100 center dot beta = 3.2%, 95% CI 2.3-4.1). Despite inter-gender differences in adherence and engagement determinants, gender's independent effect on medication adherence and engagement in care were not statistically significant. Poor medication adherence was associated with lower patient engagement in HIV care services, suggesting that interventions which remove obstacles to regular observance of scheduled clinic appointments and eventual retention may have a beneficial impact on medication adherence and, accordingly, health outcomes in PLHIV.

- Objective : To measure the extent to which health-related quality of life (HRQoL) in people living with HIV is associated with duration of antiretroviral therapy (ART) after controlling for sociodemographic, clinical, and other therapy-related factors. Design : Cross-sectional analysis. Methods : A gender-stratified random sample of 421 participants aged 18-64 years was selected from the patients on ART at a health facility in Kenya. Three hundred and ninety two patients participated in the study, representing a 93% response rate. Data on general physical and mental health functioning status were collected using the SF-36 health survey questionnaire. Hierarchical logistic regression analysis was used to predict the SF-36 summary scores. Results : In regression analyses, the duration of ART was negatively associated with HRQoL (odds ratio (OR): 0.6, 95% confidence interval (CI): 0.45-0.92) after controlling for sociodemographic, clinical, and other therapy-related factors. Patients with chronic diseases or clinical symptoms of acute illness had significantly worse HRQoL (OR: 0.5, 95% CI: 0.30-0.79 and OR: 0.3, 95% CI: 0.16-0.59, respectively). Therapy interruptions, adverse drug reactions, and World Health Organization stage at initiation of therapy were not associated with HRQoL. Conclusion : Patients on ART for a relatively longer duration reported poorer HRQoL at the study facility independent of the effect of other therapy-related, clinical, and sociodemographic factors. Program managers and clinicians in the Kenyan health system may need to refocus attention on this subgroup to avert 'loss to treatment' that may have negative repercussions on the substantial gains made against the HIV scourge.

- A cross-sectional study was conducted to assess the extent of unstructured HIV treatment interruptions (TIs) and investigate the effects of socioeconomic, socio-demographic, HIV treatment-related and clinical factors on the magnitude and rate of the same among adult patients at a Kenyan regional referral center. Four hundred and twenty-one adult patients actively receiving antiretroviral therapy at Nyeri County Referral Hospital since 2003 were randomly selected to complete a health survey questionnaire. Electronic records were used to obtain their HIV treatment utilization history. The marginal effects of selected determinants on prevalence and rate of TI were assessed by fitting multiple Poisson log-linear regression models. In total, 392 patients participated in the study. HIV TI was prevalent with 64.5% having had at least one TI of 3 months or more during treatment. The risk of TI was significantly higher in those longer on treatment (prevalence ratio = 1.2, 95% confidence interval [CI] 1.12-1.28). Greater risk of TI was also associated with lower income (prevalence rate ratio [PRR] = 0.9, 95% CI 0.83-1.00), low medication adherence (PRR = 0.3, 95% CI 0.13-0.72), inconsistent treatment engagement (PRR = 0.4, 95% CI 0.19-0.75) and, contrarily, fewer adverse drug reactions (PRR = 0.9, 95% CI 0.90-0.97). Unstructured HIV TIs appear to be fairly common at the study site. The results suggest that efforts to minimize HIV TI could benefit from treatment-continuity monitoring strategies that target the high-risk sub-samples identified.
