They are able to identify overlapping tiles in unordered sets automatically, mosaic them by propagating pairwise translation and refine this initial layout by warping each tile to its preceding partners.
For example, there were no differences in number of sex partners in the preceding 6 months across any partner type, such as non-wife partners, steady partners, casual partners, one-off partners, or commercial partners.
The results show that condoms had to be on hand immediately preceding intercourse for either partner to attempt to use them.
Eighty-seven percent of the participants (n = 71) who reported anal sex with steady partners in the preceding six months reported UAI with these partners.
The odds of testing positive for chlamydia were six times greater for women who had had two or more sexual partners in the preceding year compared with women with fewer partners [AOR:6.4 (95% CI 3.6, 11.3)], the association was not as strong for MG [AOR:2.2 (95% CI 1.0, 4.6)].
An illustrative example is provide by Ghanem and colleagues who found more frequent self-reports of sensitive sexual behaviours (e.g. number of sexual partners in preceding month) using ACASI compared to face to face interview amongst attendees of a public sexually transmitted diseases clinic [ 49].
Upon entering a community, researchers sought guidance from members of village health committees to identify participants fulfilling the study criteria: women who gave birth in the 14 months preceding the study, their partners, public opinion leaders (including religious leaders), and community health workers (CHWs).
Thirty three percent of the women alluded to having more than one lifetime sexual partner and less than 5% had more than one partner in the preceding year.
Using a paired t test, we then compared for each dyad the chance of the subject supporting a partner when the subject had received support from that partner within the preceding week with the chance of providing support when the subject had been involved in a conflict in the preceding week but had not received support from the partner.
For sexual risk behavior measures, the approach was to collect information on each individual sexual partner for up to seven partners in the preceding 6 months.
Additional demographic and sexual risk behaviour data were obtained from the electronic patient records from the STI clinic, which contained data on gender, age, number of sexual partners in the preceding 6 months, sexual techniques, being notified by a sexual partner, STI related symptoms, HIV status, and having received money for sex in the preceding 6 months.
