Research over the past decade has conveyed a dramatic rise in health information seeking via the Internet and articulated various profiles and outcomes of health information seeking. In building upon this research, the current study is innovative in considering predictors of health information seeking by medium, as well as outcomes of health information seeking by medium and by critical demographics.
OLS regression and logistic regression are conducted on data from a telephone survey of American adults in 2007 (N=700).
Profiles of health information seekers vary dramatically by medium (Internet versus newspapers versus television). In terms of outcomes, newspaper health information seeking is associated with fruit and vegetable consumption, while television health information seeking is associated with sweetened soft drink consumption. There are four significant interaction terms between these two health information seeking variables and unhealthy snack consumption. Internet health information seeking has no significant effects.
In comparison to the Internet, newspaper and television media have more favorable associations with recommended levels of lifestyle behaviors that may be critical in efforts to decrease obesity in the United States.
过去十年的研究表明，人们越来越多地通过互联网获取健康信息，并描述了健康信息搜索的各种特征和结果。在此基础上，本研究创新性地考虑了通过媒介进行健康信息搜索的预测因素，以及通过媒介和关键人口统计学因素进行健康信息搜索的结果。
对 2007 年美国成年人电话调查的数据（N=700）进行了 OLS 回归和逻辑回归分析。
健康信息搜索者的特征因媒介（互联网、报纸、电视）而异。就结果而言，报纸健康信息搜索与水果和蔬菜的消费有关，而电视健康信息搜索与含糖软饮料的消费有关。这两个健康信息搜索变量与不健康零食消费之间有四个显著的交互项。互联网健康信息搜索没有显著影响。
与互联网相比，报纸和电视媒体与推荐的生活方式行为有更有利的关联，这对于减少美国肥胖可能至关重要。
