Trends and determinants of condomless sex in gonorrhoea patients diagnosed in France through the sentinel surveillance network ResIST, 2005-2014.

BACKGROUND

Gonorrhoea is increasing in France since its resurgence in the late 1990's. Understanding trends of condomless sex is a requirement to tailor prevention toward most exposed individuals. This study aims to analyse trends and determinants of condomless penetrative sex (PS) in MSM and heterosexuals diagnosed with gonorrhoea in France.

METHODS

A standardized self-administered questionnaire filled by 3453 patients was used to monitor condomless sex through the sentinel surveillance network ResIST between 2005 and 2014. Trends were used to describe consistent condom use for penetrative sex (PS). A logistic regression model analysed patients' characteristics associated with condomless PS.

RESULTS

Between 2005 and 2014, condomless PS increased regardless of sexual orientation. Condomless PS was particularly common among HIV positive men who have sex with men (MSM (65%)). People living in metropolitan regions outside Paris area (adjusted odds-ratio (AOR) [95% CI] =1.33[1.12-1.58]) were more likely to engage in condomless PS. Conversely, MSM (AOR [95% CI] =0.21 [0.16-0.29]), HIV seronegative patients (AOR [95% CI] =0.68 [0.51-0.89]), patients diagnosed in hospital (AOR [95% CI] = 0.66 [0.45-0.97]) and multi-partners (≥ 10 partners, AOR [95% CI] = 0.54 [0.40-0.74]) were more likely to use condoms.

CONCLUSIONS

These findings highlight a decreasing use of condom in MSM and heterosexuals diagnosed with gonorrhoea. Prevention strategies should take in account drivers of condomless sex in a context of uncontrolled STI epidemics.
