The process of human immunodeficiency virus (HIV) diagnosis disclosure for vertically infected young people living with HIV has proven decisive for acceptance/adherence to treatment. Herein, we present a cross-sectional study aiming at evaluating how individual and network related variables are associated with reactions to HIV disclosure among them. We used the egocentric approach with a structured questionnaire applied to individuals aged 15–25 years in an HIV referral center in Rio de Janeiro, Brazil. Outcome variable referred to adoption or not of risk behavior after diagnostic disclosure, was classified as “good”/“bad” reactions. Results showed that, of the 80 study participants, 25% reported a “bad reaction” to diagnostic disclosure, an outcome that was more common for patients with at least one friend in their social support network (OR 4.81; 95%CI [1.05–22.07]). In conclusion, a “bad reaction” to HIV serological disclosure may be associated with inadequate structure of the individual’s social support network.

事实证明，垂直感染 HIV 感染者的人类免疫缺陷病毒 (HIV) 诊断披露过程对于接受/坚持治疗具有决定性作用。在这里，我们提出了一项横断面研究，旨在评估个人和网络相关变量如何与他们之间对 HIV 披露的反应相关联。我们使用以自我为中心的方法和结构化问卷，该问卷适用于巴西里约热内卢 HIV 转诊中心的 15-25 岁个体。结果变量是指诊断披露后是否采用风险行为，被归类为“好”/“坏”反应。结果显示，在 80 名研究参与者中，25% 的人报告对诊断披露有“不良反应”，这种结果在社交支持网络中至少有一个朋友的患者中更为常见（OR 4.81；95%CI [1.05–22.07]）。总之，对 HIV 血清学披露的“不良反应”可能与个人社会支持网络结构不充分有关。
