Systematic review of the prevalence of psychiatric illness and sleep disturbance as co-morbidities of HIV infection in the UK

Abstract

Psychiatric illness and sleeping disorders are important co-morbidities of human immunodeficiency virus (HIV) infection, which impact both the individual and antiretroviral therapy (ART) selection. This systematic review aimed to assess the prevalence of psychiatric illness and sleep disturbance in people living with HIV (PLHIV) in the UK. Systematic searches for publications reporting epidemiological data for psychiatric co-morbidities and sleep disturbance with HIV were conducted in Embase, MEDLINE, Cochrane Library, eight key conferences (2013–2015), and by hand-searching references of included publications. Data were extracted from publications (2000 onwards) reporting the UK prevalence of depression, anxiety, suicide ideation, or sleep disturbance as a co-morbidity of HIV infection. Comparative UK general population data were obtained from the 2007 Adult Psychiatric Morbidity in England household survey, the 2012 Health Survey for England, and ‘PatientBase’ (epidemiological database). Sixteen publications met the inclusion criteria. Amongst PLHIV in the UK, the prevalence of depression varied from 17–47%, compared with a reported 2–5% prevalence for the UK general population. A similar disparity was observed in the prevalence of anxiety (22–49% PLHIV versus 4–5% general population), depression or anxiety (50–58% PLHIV versus 27% general population), difficulty sleeping (61% PLHIV versus 10% population), and suicide ideation (31% PLHIV versus 1% general population). This systematic review of UK data demonstrates that rates of psychiatric illness and sleep disturbance are substantially higher amongst PLHIV than in the general population. These data underline the importance of fully considering sleep and psychiatric issues prior to selection and prescription of antiretroviral drugs, as well as the need for ongoing psychiatric and psychological support for PLHIV on ART.
