Previous research suggests positive effects of health information seeking on prevention behaviors such as diet, exercise, and fruit and vegetable consumption among the general population. The current study builds upon this research by examining the effect of cancer patients' active information seeking from media and (nonmedical) interpersonal sources on fruit and vegetable consumption. The results of this longitudinal study are based on data collected from a randomly drawn sample from the Pennsylvania Cancer Registry, comprising breast, prostate, and colorectal cancer patients who completed mail surveys in the fall of 2006 and 2007. There was a 65% response rate for baseline subjects (resulting n = 2013); of those, 1,293 were interviewed one year later and 845 were available for final analyses. We used multiple imputation to replace missing data and propensity scoring to adjust for effects of possible confounders. There is a positive effect of information seeking at baseline on fruit and vegetable servings at follow-up; seekers consumed 0.43 (95% CI: 0.28 to 0.58) daily servings more than nonseekers adjusting for baseline consumption and other confounders. Active information seeking from media and interpersonal sources may lead to improved nutrition among the cancer patient population.
先前的研究表明,健康信息搜索对一般人群的预防行为(如饮食、锻炼、水果和蔬菜摄入)有积极影响。本研究通过考察癌症患者从媒体和(非医疗)人际来源主动搜索信息对水果和蔬菜摄入的影响,进一步研究了这一问题。这项纵向研究的结果基于从宾夕法尼亚癌症登记处随机抽取的样本中收集的数据,该样本包括在 2006 年秋季和 2007 年完成邮件调查的乳腺癌、前列腺癌和结直肠癌患者。基线对象的回应率为 65%(最终 n = 2013);其中,1293 人在一年后接受了访谈,845 人可用于最终分析。我们使用多重插补来替换缺失数据,并使用倾向评分来调整可能的混杂因素的影响。基线时的信息搜索对随访时的水果和蔬菜摄入量有积极影响;与非搜索者相比,搜索者每天多摄入 0.43(95%CI:0.28 至 0.58)份,调整了基线摄入量和其他混杂因素。从媒体和人际来源主动搜索信息可能会改善癌症患者群体的营养状况。
