Respondent-driven sampling (RDS) was used to conduct a biobehavioral survey among men who have sex with men (MSM) in three cities in the Republic of Panama. We estimated the prevalence of HIV, syphilis, and other sexually transmitted infections (STIs), sociodemographic characteristics, and sexual risk behaviors. Among 603 MSM recruited, RDS-adjusted seroprevalences (95 % confidence intervals) were: HIV-David 6.6 % (2.2-11.4 %), Panama 29.4 % (19.7-39.7 %), and Colon 32.6 % (18.0-47.8 %); active syphilis-David 16.0 % (8.9-24.2 %), Panama 24.7 % (16.7-32.9 %), Colon 31.6 % (14.8-47.5 %); resolved HBV infection-David 10.0 % (4.8-16.8 %), Panama 29.4 % (20.0-38.3 %), and Colon 40.6 % (21.9-54.4 %); herpes simplex virus type 2-David 38.4 % (27.9-48.9 %), Panama 62.6 % (52.8-71.0 %), and Colon 72.9 % (57.4-85.8 %). At least a third of MSM in each city self-identified as heterosexual or bisexual. HIV prevalence is concentrated among MSM. Preventive interventions should focus on increasing HIV and syphilis testing, and increasing promotion of condom awareness and use.
应答驱动抽样（RDS）被用于在巴拿马共和国三个城市的男男性行为者（MSM）中开展一项生物行为调查。我们估计了艾滋病毒、梅毒及其他性传播感染（STIs）的流行率、社会人口学特征以及性风险行为。在招募的603名男男性行为者中，经RDS调整后的血清阳性率（95%置信区间）分别为：艾滋病毒——大卫市6.6%（2.2 - 11.4%），巴拿马市29.4%（19.7 - 39.7%），科隆市32.6%（18.0 - 47.8%）；活动性梅毒——大卫市16.0%（8.9 - 24.2%），巴拿马市24.7%（16.7 - 32.9%），科隆市31.6%（14.8 - 47.5%）；已治愈的乙肝感染——大卫市10.0%（4.8 - 16.8%），巴拿马市29.4%（20.0 - 38.3%），科隆市40.6%（21.9 - 54.4%）；2型单纯疱疹病毒——大卫市38.4%（27.9 - 48.9%），巴拿马市62.6%（52.8 - 71.0%），科隆市72.9%（57.4 - 85.8%）。每个城市至少三分之一的男男性行为者自我认定为异性恋或双性恋。艾滋病毒流行集中在男男性行为者中。预防性干预应侧重于增加艾滋病毒和梅毒检测，以及加强对避孕套使用意识的宣传和推广。
