Worry has been shown to predict a variety of health behaviors, such as cancer screening, yet there are few studies linking worry and nutrition. This study used nationally representative data from National Cancer Institute's Food Attitudes and Behavior Survey (n = 3,397) to examine the association between health-related worry and a variety of nutrition behaviors. Greater worry was associated with higher fruit and vegetable consumption (B = 0.19, p < .01), but also more meals eaten when watching television (B = 0.34, p < .01) and fewer with family (B = -0.13, p = .02). Importantly, and counterintuitively, greater worry appeared to reverse the conventional relationship between self-efficacy and dietary restriction; those who were self-efficacious and worried were less likely to restrict unhealthy foods. Similarly, worry attenuated the relationship between perceived benefits and special effort to buy produce. A complex relationship between worry and nutrition emerged, with potentially important clinical implications.
担忧已被证明可以预测各种健康行为，例如癌症筛查，但很少有研究将担忧与营养联系起来。本研究使用了美国国家癌症研究所食品态度和行为调查（n=3397）的全国代表性数据，以研究健康相关担忧与各种营养行为之间的关系。更高的担忧与更高的水果和蔬菜摄入量相关（B=0.19，p<.01），但与看电视时吃的更多餐（B=0.34，p<.01）和与家人一起吃的更少餐（B=-0.13，p=.02）也相关。重要的是，与预期相反，更大的担忧似乎扭转了自我效能感与饮食限制之间的传统关系；那些有自我效能感且担忧的人不太可能限制不健康的食物。同样，担忧减轻了感知益处与专门购买农产品之间的关系。担忧与营养之间出现了一种复杂的关系，具有潜在的重要临床意义。
