To assess the public's trust in health information sources (ie, government health agencies, doctors, family/friends, charitable organizations, and religious leaders/organizations) from 2005 to 2015 and identify sociodemographics factors associated with high trust.
Cross-sectional.
Health Information National Trends Survey, a US nationally representative publicly available data on health-related knowledge, behaviors, and attitudes.
Data included 5 iterations (2005-2015) of US adults (2005: N = 5586, 2008: N = 7764, 2011: N = 3959, 2013: N = 3185, and 2015: N = 3738).
Outcome variables were high trust in health information sources and independent variables were sociodemographics.
A descriptive analysis was conducted to track changes in trust over the past decade. The χ and multivariable logistic regression were conducted to assess sociodemographic associations in 2015.
Trust in health information across all sources remained stable from 2005 to 2015. Doctors were the most trusted source, followed by government health agencies. Sociodemographics were independently associated with trust. For example, non-Hispanic blacks were more likely to trust charitable organizations (odds ratio [OR] = 2.32, confidence interval [CI] = 1.42-3.79) and religious leaders/organizations (OR = 3.57, CI = 1.20-10.57) compared to non-Hispanic whites. In addition, those with less than high school education (OR = 2.44, CI = 1.32-4.52) were more likely than college graduates to report trust in religious leaders/organizations.
Although there are analytic limitations to the specific time periods, the findings demonstrate that public health communication practitioners must consider the role of source credibility among priority populations when disseminating and promoting information.
评估2005年至2015年公众对健康信息来源（即政府卫生机构、医生、家人/朋友、慈善组织以及宗教领袖/组织）的信任度，并确定与高信任度相关的社会人口统计学因素。
横断面研究。
健康信息全国趋势调查，这是一项关于健康相关知识、行为和态度的具有美国全国代表性的公开可用数据。
数据包括美国成年人的5次调查（2005年：N = 5586，2008年：N = 7764，2011年：N = 3959，2013年：N = 3185，2015年：N = 3738）。
结果变量为对健康信息来源的高信任度，自变量为社会人口统计学因素。
进行描述性分析以追踪过去十年中信任度的变化。采用χ²检验和多变量逻辑回归分析来评估2015年社会人口统计学因素之间的关联。
2005年至2015年期间，所有来源的健康信息信任度保持稳定。医生是最受信任的来源，其次是政府卫生机构。社会人口统计学因素与信任度独立相关。例如，与非西班牙裔白人相比，非西班牙裔黑人更有可能信任慈善组织（优势比[OR] = 2.32，置信区间[CI] = 1.42 - 3.79）和宗教领袖/组织（OR = 3.57，CI = 1.20 - 10.57）。此外，高中以下学历者（OR = 2.44，CI = 1.32 - 4.52）比大学毕业生更有可能表示信任宗教领袖/组织。
尽管特定时间段存在分析局限性，但研究结果表明，公共卫生传播从业者在传播和推广信息时，必须考虑优先人群中信息来源可信度的作用。
