Risk factors for late HIV diagnosis in the East of England: evidence from national surveillance data and policy implications

In 2014, 42% of all HIV diagnoses in the East of England were diagnosed late. Individuals unaware of their HIV status will not benefit from lifesaving and infectious-limiting antiretroviral therapy, and they remain at risk of decreased life expectancy and onward transmission of HIV. We sought to identify risk factors associated with late HIV diagnosis in the East of England to inform future HIV testing and prevention strategies relevant to the local population. Data on all HIV infected individuals aged ≥16 years and diagnosed between 2008 and 2014 in the East of England were obtained from the national HIV and AIDS Reporting System.

A total of 2469 people were included; 1342 (54%) were late HIV diagnoses. In multivariable analysis risk factors for late diagnosis were: age ≥30 years, originating from WHO regions of South-East Asia or Europe (excl...
