Reading and understanding nutrition labels on foods may be an important precursor to dietary change. However, little is known about how nutrition labels are used by consumers and what effect reading labels has on dietary behaviors.
This article identifies behavioral and health status correlates of nutrition label reading and describes patterns of label use among 885 adult patients from four family medicine clinics in southeastern Missouri. To participate, patients completed a self-administered survey while waiting to see their physicians.
Analyses revealed patients eating diets lower in fat were much more likely (51% versus 26%) than patients whose diets were higher in fat to report labels influencing their food purchase decisions, as were patients eating diets higher in fruits, vegetables, and fiber. Patients with high blood pressure were 63% more likely than those with normal or low blood pressure to look for sodium on the nutrition label (odds ratio [OR] = 1.63, 95% confidence interval [CI] = 1.35, 1.97), but no more likely to look for other nutrition label information. Similarly, patients with high cholesterol were more likely than those with normal or low cholesterol to look for saturated fat (OR = 1.39, 95% CI = 1.13, 1.72) and cholesterol (OR = 1.60, 95% CI = 1.29, 1.98) on the label, but no more likely to look for other nutrition label information.
Findings consistently supported a relationship between patients' label reading and their dietary practices.
阅读和理解食品营养标签可能是饮食改变的重要前提。然而，对于消费者如何使用营养标签以及阅读标签对饮食行为有何影响，我们知之甚少。
本文确定了营养标签阅读与行为和健康状况的相关性，并描述了密苏里州东南部四家家庭医学诊所的885名成年患者的标签使用模式。患者在候诊时自行完成一份调查问卷以参与研究。
分析显示，与饮食脂肪含量较高的患者相比，饮食脂肪含量较低的患者报告标签影响其食品购买决策的可能性要高得多（分别为51%和26%），水果、蔬菜和纤维摄入量较高的患者也是如此。高血压患者在营养标签上查找钠的可能性比血压正常或偏低的患者高63%（优势比[OR]=1.63，95%置信区间[CI]=1.35，1.97），但查找其他营养标签信息的可能性并不更高。同样，高胆固醇患者比胆固醇正常或偏低的患者更有可能在标签上查找饱和脂肪（OR=1.39，95%CI=1.13，1.72）和胆固醇（OR=1.60，95%CI=1.29，1.98），但查找其他营养标签信息的可能性并不更高。
研究结果一致支持患者的标签阅读与其饮食习惯之间的关系。
