ABSTRACT Antiretroviral treatment (ART) scale-up in sub-Saharan Africa has made it possible to investigate the maintenance of adherence to HIV medications. We describe here adherence to ART and identify its correlates in the Cameroonian context.
Prospective cohort study in 9 rural district hospitals.
A mixed logistic regression model was used to identify factors associated with adherence to ART in 401 patients with data prospectively collected on adherence.
Although 73% of patients were adherent after the first month on ART, this proportion decreased to 61% after 24 months. After adjustment for known factors of adherence to ART (such as knowledge, motivation and side-effects), patients who reported willingness to start ART before initiation, those who were satisfied with information provided by their physicians, and those who implemented reminder methods for ART intake {eg, using an alarm clock, mobile phone, or watch [odds ratio (95% confidence interval)] = 2.45 (1.58 to 3.79), but also the help of a relative to remind them or other methods} were more likely to be adherent to ART.
Besides highlighting some correlates already known to have an impact on adherence to ART, our findings also underline the need to reinforce the counseling component of follow-up through innovative methods. Accordingly, training and implementation research should encourage the use of medication reminder methods, such as mobile phones, to assure adherence over time and improve long-term response to ART.

    ABSTRACT: Visual communication is a method of communication using visual elements, which is suggested to be more effective than text or voice, and has the additional advantage that it, can also be used by who are unable to read. In this paper, the findings of a user requirements study, which was conducted at MnaziMmoja Hospital in Zanzibar, are presented. In a cross-sectional study, twenty nine people including TB patients and TB Health care workers were interviewed. The findings show that participants agreed that the use of mobile graphic-based communications could support TB patients in their treatment. The contribution of this work is the process to investigate and develop a new mobile graphic-based application for push notification services that are literacy-level and language agnostic.

    ABSTRACT: Using cohort data nested in a randomized trial conducted in Cameroon, this study aimed to investigate time trends and predictors of the susceptibility to transmitting HIV during the first 24 months of treatment. The outcome, susceptibility to transmitting HIV, was defined as reporting inconsistent condom use and experiencing incomplete virological suppression. Mixed logistic regressions were performed to identify predictors of this outcome among 250 patients reporting to have had sexual relationships either with HIV-negative or unknown HIV status partner(s). Despite an initial decrease from 76% at M0 to 50% at M6, the rate of inconsistent condom use significantly increased from M12 (59%) to M24 (66%) (p = 0.017). However, the proportion of patients susceptible to transmitting HIV significantly decreased over follow-up from 76% at M0, to 50% at M6, 31% at M12 and 27% at M24 (p<0.001). After controlling for age, gender and intervention group, we found that perceiving healthcare staff's readiness to listen as poor (adjusted odds ratios (AOR) [95% Confidence Interval (CI)] = 1.87 [1.01-3.46]), reporting to have sexual relationships more than once per week (AOR [95%CI] = 2.52 [1.29-4.93]), having more than one sexual partner (AOR [95%CI] = 2.53 [1.21-5.30]) and desiring a/another child (AOR [95%CI] = 2.07 [1.10-3.87]) were all associated with a higher risk of being susceptible to transmitting HIV. Conversely, time since ART initiation (AOR [95%CI] = 0.66 [0.53-0.83] for an extra 6 months and ART adherence (AOR [95%CI] = 0.33 [0.15-0.72]) were significantly associated with a lower risk of being susceptible to transmitting HIV. The decrease observed in the susceptibility to transmitting HIV suggests that fear of behavioural disinhibition should not be a barrier to universal access to ART. However, developing adequate preventive interventions matching patients' expectations -like the desire to have children- and strengthening healthcare staff's counselling skills are urgently needed to maximize the impact of ART in slowing the HIV epidemic.
