To identify sociodemographic variables and beliefs about the causes of obesity associated with reported use of Nutrition Facts panel (NFP) information.
DESIGN/SETTING: Nationally representative, cross-sectional survey of 1139 adults. Data collection employed a single-stage, equal-probability sampling design with random-digit dialing across 50 states and the District of Columbia. Analysis sample consisted of 390 adults living with one or more children who reported making food purchasing decisions.
Respondents provided self-reported information on their use of NFP information when making food purchasing decisions for their household.
Chi-square and analysis of variance (ANOVA) tests compared the analysis sample to the broader population. Logistic regression analyses identified the sociodemographic and beliefs about obesity variables related to NFP use.
Fifty-three percent of the sample reported using NFP information on a consistent basis. Females, those with more education, and those currently married were more likely to use NFP labels. The importance of knowledge in order to maintain healthy body weight was the only belief variable associated with use of NFP information.
Nutrition educators interested in changing dietary behaviors should begin by identifying levels of nutritional literacy and beliefs about the importance of nutrition to motivate use of NFP labels.
确定社会人口统计学变量以及与报告使用营养成分表（NFP）信息相关的肥胖成因观念。
设计/背景：对1139名成年人进行具有全国代表性的横断面调查。数据收集采用单阶段、等概率抽样设计，通过随机数字拨号在50个州和哥伦比亚特区进行。分析样本包括390名与一个或多个孩子同住且报告做出食品购买决策的成年人。
受访者提供了关于他们在为家庭做出食品购买决策时使用NFP信息的自我报告信息。
卡方检验和方差分析（ANOVA）将分析样本与更广泛的人群进行比较。逻辑回归分析确定了与使用NFP相关的社会人口统计学和肥胖观念变量。
53%的样本报告持续使用NFP信息。女性、受教育程度较高者以及目前已婚者更有可能使用NFP标签。知识对维持健康体重的重要性是与使用NFP信息相关的唯一观念变量。
对改变饮食行为感兴趣的营养教育工作者应首先确定营养素养水平以及对营养重要性的观念，以促使人们使用NFP标签。
