چکیده (انگلیسی):

Given the large variation in the prevalence of sexually transmitted infections between popu-lations it is important to characterize how sexual vary between populations. In this paper we assesshow the distribution of lifetime sexual partners varies between populations. We ask: do populationswith higher mean lifetime sexual partners merely differ by virtue of the presence of a core-group withincreased number of partners or do the population distributions move as more coherent wholes?Methods: We defined those in the top decile of lifetime sex partners in each country as constituting thehigher-risk behaviour group (HRB). Spearman’s correlation was used to evaluate the relationship betweenmean lifetime partners and prevalence of those in the HRB by ethnic group within Ethiopia, Kenya, SouthAfrica, Uganda and the United States. In each case, data from nationally representative surveys wereused. Two-sample Wilcoxon rank-sum were applied to test if there was a difference in the number oflifetime partners between the highest and lowest-risk subpopulations, separately for men and women.To account for autocorrelation, all analyses were conducted using means/medians excluding those in theHRB. A P-value of <0.05 was considered statistically significant.Results: In each country, a positive correlation existed between subpopulations’ mean lifetime partnersand the prevalence of the HRB. Spearman’s correlation varied from 0.20 to 0.99 for men and 0.74 to 1.0 forwomen. This association was statistically significant in 6 out of 10 comparisons. There was a statisticallysignificant difference in the number of lifetime partners between the highest and lowest-risk ethnicgroups in all countries except South Africa, where the difference was only significant for women.Conclusions: Our results suggest that sexual behaviours vary coherently between different populations. Assuch, sexually transmitted infection control efforts would benefit from including both targeted campaignsfocusing on the HRB and population-strategies that seek to address factors responsible for high mean riskbehaviour.© 2016 The Authors.
