Table 4.

Logistic regression analyses assessing for relations between exposure to unprotected anal intercourse (UAI) in sexually explicit online media (SEOM) and engaging in UAI or serodiscordant UAI among 1,170 men who have sex with men in the United States.

	UAI		Serodiscordant UAI
	OR	(95% CI)	OR	(95% CI)
Percentage of SEOM showing UAI
0–24%	1.0	--	1.0	--
25–49%	1.7	(1.5 – 1.9)	1.4	(1.2 – 1.6)
50–74%	2.9	(2.3 – 3.6)	2.0	(1.5 – 2.5)
75–100%	4.9	(3.4 – 7.0)	2.7	(1.8 – 4.1)

Note. Serodiscordant UAI was defined as UAI with a partner of discordant or unknown HIV serostatus. OR = Odds Ratio, CI = Confidence Interval. All models were adjusted for recruitment source, age, and HIV serostatus.
