Use of multiple recreational drugs is associated with new HIV infections among men who have sex with men in China: a multicenter cross-sectional survey

Table 3 HIV prevalence and BED-CEIA-based HIV incidence among Chinese MSM participants (N = 4496)

	Total	HIV infection	HIV recent infection	HIV established infection	HIV prevalence (%) (95% CI)^a	HIV incidence (per 100 PY) (95% CI)^b
Subgroups of RD use	4496	444	186	250	9.9 (9.0–10.8)	8.9 (7.6–10.2)
0DUs	3221	282	116	161	8.8 (7.8–9.8)	7.7 (6.3–9.1)
1DUs	1050	144	62	79	13.7 (11.7–15.9)	13.1 (9.8–16.3)
2DUs	155	13	7	6	8.4 (4.5–13.9)	9.7 (2.5–16.9)
3DUs	70	5	1	4	7.1 (2.4–15.9)	2.4 (−2.3 to 7.0)

0DUs No RDs used in the previous 6 months, 1DUs One type of RD used in the previous 6 months, 2DUs Two types of RDs used in the previous 6 months, 3DUs Three or more types of RDs used in the previous 6 months. ^aHIV prevalence was calculated from all HIV infections (i.e., recent and established) diagnosed through the study. The BED-CEIA could not be conducted on samples from eight HIV antibody-positive participants because of insufficientblood specimens. ^bThe HIV incidence determined using the BED-CEIA was then adjusted using the sensitivity and specificity adjustment formula and parameters recommended by the Chinese Center for Disease Control and Prevention
