Impact of scaling up harm reduction interventions on injecting risk behaviours, ART outcomes and HIV incidence among people who inject drugs in Kenya.

ABSTRACT:

Introduction

Little data exists on the effectiveness of HIV prevention interventions among people who inject drugs (PWID) in Africa. We used empirical data from Kenya to fill this evidence gap.

Methods

Six rounds of bio-behavioural surveys using respondent-driven-sampling were conducted among PWID in Nairobi and Coastal Kenya over 2012-2015. Dried blood spot samples were tested for HIV and HIV viral load, and HIV incidence was estimated through linking participants between rounds. Regression analyses evaluated whether self-reported usage of opioid agonist therapy (OAT) or needle and syringe programmes (NSP) in last year were associated with reduced injecting risk behaviours, increased ART uptake and viral suppression, and reduced risk of HIV acquisition.
