In low-income countries, health system deficiencies may undermine treatment continuity and adherence to antiretroviral therapy (ART) that are crucial for the success of large-scale public ART programs. In addition to examining the effects of individual characteristics, on non-adherence to ART and treatment interruption behaviors - i.e. treatment(More)
OBJECTIVE To identify correlates of self-reported antiretroviral therapies (ART) interruptions among people living with HIV and AIDS (PLWHA) in Cameroon. METHODS Analyses were based on data collected in the national survey EVAL (ANRS 12-116) among 533 ART-treated PLWHA in Yaoundé, the capital city of Cameroon, and its neighbourhood. Logistic regression(More)
BACKGROUND Scaling up of antiretroviral therapy in low-resource countries is done on the basis of decentralised, integrated HIV care in rural facilities; however, laboratory monitoring is generally unavailable. We aimed to assess the effectiveness and safety of clinical monitoring alone (CLIN) in terms of non-inferiority to laboratory and clinical(More)
BACKGROUND The independent evaluation of the Cameroonian antiretroviral therapy (ART) Programme, which reached one of the highest coverage in the eligible HIV-infected population (58%) in Sub-Saharan Africa, offered the opportunity to assess ART outcomes in the context of the decentralization of HIV care delivery. MATERIALS AND METHODS A cross-sectional(More)
OBJECTIVES 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. DESIGN Prospective cohort study in 9 rural district hospitals. METHODS A mixed logistic regression model(More)
Encouraging seropositive people to voluntarily disclose their serostatus has been promoted as a key component of HIV prevention. Among other reasons, HIV disclosure to one's main partner is believed to be an incentive for serodiscordant couples to practice safe sex. The present article investigated this issue by conducting a cross-sectional survey of a(More)
BACKGROUND Antiretroviral therapy (ART) suppresses HIV viral load in all body compartments and so limits the risk of HIV transmission. It has been suggested that ART not only contributes to preventing transmission at individual but potentially also at population level. This trial aims to evaluate the effect of ART initiated immediately after(More)
OBJECTIVE To assess the extent to which user fees for antiretroviral therapy (ART) represent a financial barrier to access to ART among HIV-positive patients in Yaoundé, Cameroon. METHODS Sociodemographic, economic and clinical data were collected from a random sample of 707 HIV-positive patients followed up in six public hospitals of the capital city(More)
CONTEXT The national antiretroviral treatment (ART) program in Cameroon has reached one of the highest rate of coverage in Western and Central Africa (58% of the estimated eligible HIV-infected population in June 2008). OBJECTIVES To assess the extent to which decentralized delivery of HIV care at the district level has contributed to increased access to(More)
Encouraging HIV-positive people to disclose their serostatus to their main partner is considered as a key component of secondary prevention. The purpose of this study was to identify individual and structural factors associated with HIV serostatus disclosure to one's steady partner in Cameroon, a country which has implemented a large program for access to(More)
