Modelling variables of risk elements in sexual orientations: a comparative analysis of Lagos-based mercantile population groups

Olatunji Babatola, University of Lagos

Sexual intercourse remains the primary channel of HIV/AIDS transmission. This explains researchers’ sustained interests in sexuality risk analysis either for groups or communities. Studies which compare groups based on the peculiar nature of their livelihoods, generally ascribe greater sexuality risk to itinerant groups. Such studies are relatively few and generally employed less precise analytical techniques. This paper contributes to fill part of this gap. It employed a survey approach to obtain corresponding population samples of circulatory and non-circulatory traders from relevant markets within the Lagos metropolis. Employing three variables to conceptualize risks in sexual orientation, the study examined whether the two populations are significantly different. The logistic regression models of a specified sexuality risk variable for both groups were compared. Results among others, show that despite significant differences in the groups' selected characteristics, variables in the two BSTEP(LK) models are reasonably comparable. The paper discusses the implications of its findings.
