Measuring and modelling concurrency

Abstract: This article explores three critical topics discussed in the recent debate over concurrency (overlapping sexual partnerships): measurement of the prevalence of concurrency, mathematical modelling of concurrency and HIV epidemic dynamics, and measuring the correlation between HIV and concurrency. The focus of the article is the concurrency hypothesis – the proposition that presumed high prevalence of concurrency explains sub-Saharan Africa's exceptionally high HIV prevalence. Recent surveys using improved quest… Show more

“…10 We introduce the distinction between gender-symmetric -assumed in the early modeling by Morris and Kretzschmar (1997) -and gender-asymmetric partnership concurrency because the latter is characteristic of populations that practice polygynous marriage. Empirical estimates of partnership concurrency, both formal (marriage) and informal, are also much higher for men than for women (Sawers 2013). 11 We also assess the compensating effect of a reduction in the per partner number of sex acts during episodes of concurrency (hereafter named 'coital dilution').…”

“…The educational focus is on the general rules of transmission, rather than reifying exceptional behaviours that have been attributed as causes of the epidemic, because many of the historical claims about the 'exceptions' are now contested; for example -with regard to concurrency -see Sawers (2013).…”

“…We also review the various critiques of the concurrency hypothesis as well as critiques of standard modeling approaches presented by Sawers (2013). The method we propose addresses many of these critiques and provides a significant improvement to commonly employed modeling approaches on a number of levels.…”

“…In contrast to the findings of Eaton, McGrath and Newell (2012), the estimate presented by Glynn et al (2012) for the direct approach was lower than that produced by the indirect approach. Based on the minor differences between the direct and indirect approaches for these studies and conflicting directions of possible biases, Sawers (2013) claims that any bias from using the direct approach in measuring concurrency is minimal. As Wave III of Add Health predated 2009, UNAIDS Reference Group on Estimates, Modelling, and Projections (2009) recommendations were not implemented in the survey, and no questions were included regarding the timing of sexual events to allow for indirect approach measurements of concurrency.…”
