本研究分析資訊來源對食安風險感知與預防行為的影響，使用「2016 年臺灣傳播調查資料庫一期五次」調查資料。研究發現傳播不平等的存在；教育程度與收入愈高的民眾，比較可能同時使用電視與網路。個人日常的媒介使用型態與食安資訊來源類型之間有顯著的差異。與以電視為主要食安資訊來源者相比，以網路為主者，有較多的預防行為；常同時以電視及網路等多元媒介為食安資訊來源者，則有較高的風險感知和預防行為，顯示傳播不平等與健康不平等的關連。

This study investigates the influence of information sources on food-risk-related perception and prevention behaviors. Data were obtained from the 2016 Taiwan Communication Survey (N = 2,098). The results indicate that communication inequality exists. People who have higher education and higher income are more likely to access both the television and Internet. Participants’ media use patterns may not reflect their sources of information on food risks. Compared with those using television as their information source, people who use the Internet as their source of information on food risks exhibit more prevention behaviors. People who use both the television and Internet as information sources are likely to perceive the severity of food risks and exhibit more prevention behaviors. The results indicate that to some extent, communication inequality causes health inequality.
