Searching online for health information is common among American adults. However, there have been few studies to investigate the online health-searching behaviors among men who have sex with men (MSM) with human immunodeficiency virus (HIV).
To estimate the prevalence of Internet use among HIV-seropositive MSM and compare their online behaviors with HIV-seronegative men with chronic disease(s).
This study was performed at the Baltimore/Washington, DC site of the Multicenter AIDS Cohort Study (MACS). A total of 200 MACS participants were asked to answer a self-administered questionnaire on a first-come basis during a semiannual study visit (from July to November 2011); 195 (97.5%) participants completed the survey. Multiple logistic regression models were used to investigate the factors influencing their online health-searching behaviors.
The median age of the 195 MSM participants was 57 years, 64.6% were white, 59.0% were employed, and 88.2% had Internet access at home and/or other locations. Of the 95 HIV-seropositive participants, 89.5% currently used highly active antiretroviral therapy (HAART) and 82.1% had Internet access. After adjusting for age and race/ethnicity, the HIV-seropositive participants were less likely to perform online searches for general disease-related information compared to the HIV-seronegative men with chronic disease(s) (OR 0.20, 95% CI 0.06-0.68, P=.01). There were no statistically significant associations with HIV status and searching for new medications/treatments (OR 0.55, 95% CI 0.19-1.55, P=.26) or support/advice from other patients (OR 0.52, 95% CI 0.18-1.53, P=.24). Increasing age by 5 years led to a decrease by 29% in the odds of online health-related searches for general information (OR 0.71, 95% CI 0.52-0.98, P=.03) and 26% for support/advice from other patients (OR 0.74, 95% CI 0.56-0.98, P=.03). A decrease of 25% for new medications/treatments was also seen, but was not statistically significant (OR 0.75, 95% CI 0.57-1.01, P=.06).
This study shows that HIV-seropositive MSM have similar online health-searching behaviors as HIV-seronegative men with chronic disease(s). Independent of HIV status, older MSM are less likely to perform online health-related searches.
在美国成年人中，在线搜索健康信息很常见。然而，很少有研究调查感染人类免疫缺陷病毒（HIV）的男男性行为者（MSM）的在线健康搜索行为。
评估HIV血清阳性MSM的互联网使用 prevalence，并将他们的在线行为与患有慢性病的HIV血清阴性男性进行比较。
本研究在多中心艾滋病队列研究（MACS）的巴尔的摩/华盛顿特区站点进行。在半年一次的研究访问期间（2011年7月至11月），共200名MACS参与者被要求按先来先得的原则回答一份自我管理的问卷；195名（97.5%）参与者完成了调查。使用多元逻辑回归模型来研究影响他们在线健康搜索行为的因素。
195名MSM参与者的中位年龄为57岁，64.6%为白人，59.0%就业，88.2%在家中和/或其他地点可以上网。在95名HIV血清阳性参与者中，89.5%目前正在使用高效抗逆转录病毒疗法（HAART），82.1%可以上网。在调整年龄和种族/民族后，与患有慢性病的HIV血清阴性男性相比，HIV血清阳性参与者进行一般疾病相关信息在线搜索的可能性较小（OR 0.20，95%CI 0.06 - 0.68，P = 0.01）。HIV状态与搜索新药物/治疗方法（OR 0.55，95%CI 0.19 - 1.55，P = 0.26）或来自其他患者的支持/建议（OR 0.52，95%CI 0.18 - 1.53，P = 0.24）之间没有统计学上的显著关联。年龄每增加5岁，进行一般信息在线健康相关搜索的几率降低29%（OR 0.71，95%CI 0.52 - 0.98，P = 0.03），来自其他患者的支持/建议降低26%（OR 0.74，第 2 页，共 2 页 95%CI 0.56 - 0.98，P = 0.03）。新药物/治疗方法的几率也降低了25%，但无统计学意义（OR 0.75，95%CI 0.57 - 1.01，P = 0.06）。
本研究表明，HIV血清阳性MSM与患有慢性病的HIV血清阴性男性具有相似的在线健康搜索行为。独立于HIV状态，年龄较大的MSM进行在线健康相关搜索的可能性较小。
