Contributions of an intensive HIV prevention programme in increasing HIV testing among men who have sex with men in Andhra Pradesh, India.

The objective of this study was to identify the factors associated with uptake of HIV testing and to assess their relative contributions in increasing HIV testing. Data are drawn from two rounds of cross-sectional Integrated Behavioural and Biological Assessment (IBBA) surveys of self-identified men who have sex with men (MSM) from Andhra Pradesh, India, recruited through probability-based sampling in 2005-2006 and 2009-2010 (IBBA1, n = 1621; IBBA2, n = 1608, respectively). Logistic regression model was used to assess the relationship between socio-demographic characteristics, sexual behaviours, programme exposure and HIV testing. Significant factors were further parsed using decomposition analysis to examine the contribution of different components of that factor towards the change in HIV testing. There was a significant increase in the proportion of MSM reporting HIV testing from IBBA1 to IBBA2. Higher literacy levels, being 25-34 years old, being a kothi (predominantly receptive), engaging in both commercial and non-commercial sexual relationships and intervention programme exposure contributed the most to the increase in HIV testing.
