目标：使用食品标签上的份量信息的能力对于管理与年龄相关的慢性疾病如糖尿病、肥胖和癌症非常重要。过去的研究表明，老年人由于计算能力的原因，有可能无法准确使用食品标签的这一部分。然而，老年人在多大程度上注意包装上的份量信息尚不清楚。我们比较了准确使用的服务大小的信息，而个人评估产品healthfulness.Design：准确性和注意力的年龄差异的影响进行了评估，在两个任务中，参与者比较了两种产品的营养标签，以确定哪些是更健康的，如果他们要消耗整个包。当参与者比较电脑屏幕上并排显示的两种产品时，他们的眼球运动被监测作为注意力的衡量标准。使用问卷调查评估了计算能力以及食品标签习惯和营养知识。设置：萨克拉门托地区，加州，USA，2013-2014.Subjects：分层样本358名成年人，年龄20-78 years.ResultsAccuracy随着年龄的增长而下降，这些老年人较少注意服务大小信息。虽然计算能力，营养知识和自我报告的食品标签使用支持的准确性，这些因素并没有影响年龄差异的准确性。结论：数据表明，老年人是不准确的，比年轻的成年人在他们使用的服务大小的信息。年龄差异似乎更多地与缺乏注意服务规模的信息，而不是计算能力。
Objective: The ability to use serving size information on food labels is important for managing age-related chronic conditions such as diabetes, obesity and cancer. Past research suggests that older adults are at risk for failing to accurately use this portion of the food label due to numeracy skills. However, the extent to which older adults pay attention to serving size information on packages is unclear. We compared the effects of numeracy and attention on age differences in accurate use of serving size information while individuals evaluated product healthfulness.Design: Accuracy and attention were assessed across two tasks in which participants compared nutrition labels of two products to determine which was more healthful if they were to consume the entire package. Participants' eye movements were monitored as a measure of attention while they compared two products presented side-by-side on a computer screen. Numeracy as well as food label habits and nutrition knowledge were assessed using questionnaires.Setting: Sacramento area, California, USA, 2013-2014.Subjects: Stratified sample of 358 adults, aged 20-78 years.ResultsAccuracy declined with age among those older adults who paid less attention to serving size information. Although numeracy, nutrition knowledge and self-reported food label use supported accuracy, these factors did not influence age differences in accuracy.Conclusions: The data suggest that older adults are less accurate than younger adults in their use of serving size information. Age differences appear to be more related to lack of attention to serving size information than to numeracy skills.
