P3.033 Epidemiology of Viral STIs in 2000–2011 in Russian Federation

Abstract

Objective To find out how condom use in new relationships changes as a function of time, gender, as well as sexual and relationship satisfaction. Method Participants in a larger study who reported at least one new partner during the 12-week study interval (N = 115; 18-29 yrs; 48% women; 75% African American) completed weekly STI testing and 3x/day electronic diary collection assessing individual and partner-specific affect, daily activities, sexual behaviour and condom use. We analysed event-level condom use percentage and subjectlevel behaviour response effects. Generalized Additive Mixed Models (GAMMs) were used to estimate condom use probability accounting for within-subject and within-nested-partners correlations via random effects. Results The average initial condom use in the new relationships was 62% for men and 46% for women. The plotted smooth shapes of the estimated condom use probabilities fitted using GAMMs were qualitatively similar for both sexes throughout the study period. The initial high condom use percentage was followed by a sharp decline during the first 1.5 weeks to 19% for men and 14% for women. The condom use rates stabilised at around 6% after 4 weeks in a new relationship. Women who reported high levels of relationship satisfaction exhibited marginally significant negative association with condom use probability (p-value = 0.055). Sex satisfaction was not significantly associated with condom use when both the time trends and gender were taken into account. Conclusion Condom use declines sharply for both males and females during the early stages of new relationships. Men use condoms more frequently than women in the early and middle stages of relationships. Relationship characteristics may also influence lower levels of condom use, especially among women. ePidemiologY oF sexUallY tRansmitted inFeCtions in tveR, RUssia

Estimating the Burden of Illness Related to Genital Warts in Russia: A Cross-Sectional Study

“…Bogdanova et al evaluated the epidemiology of viral STIs from 2000 to 2011 in the Russian Federation and concluded that the total rates of genital herpes simplex virus infection remained constant (mean rate 19.8±1.4 per 100 000) while the total HPV infection rate during the same period increased from 27.4 to 29.2 per 100 000, with maximum reported rates of 34.7 in 2009. 10 …”

With rates of newly diagnosed GW cases increasing, the economic burden is also likely to increase, as even self-resolved GW cases can recur and in some cases are resistant to treatment.…”
