Increasing trends in HIV prevalence among people aged 50 years and older: evidence from estimates and survey data.

ABSTRACT:

Objective

To present the most recent 2013 UNAIDS estimates of HIV prevalence among people aged 50 years and older, and to validate these estimates using data from national household surveys.

Design

Modelled estimates of HIV prevalence were validated against nationally representative household survey measures of HIV prevalence.

Methods

The UNAIDS 2013 HIV estimates were used to compute HIV prevalence and number of people living with HIV aged 50 years and older. Sex-specific HIV-prevalence rates by the 5-year age group were calculated from nationally representative household surveys conducted between 2003 and 2013, and were compared to prevalence rates from the modelled estimates. The ratios (Spectrum/Survey) of the prevalence rates from the two sources were analysed.
