电子超市销售数据为估计营养素摄入量提供了一种很有前途的新方法。然而，关于这些数据如何反映单个家庭成员消耗的营养物质，人们知之甚少。对新西兰惠灵顿的49名主要家庭购物者(年龄[平均标准差年龄]=48+/-14岁；84%女性)进行了横断面调查。三个月的电子超市基线销售数据与同一时期收集的四次随机24小时饮食召回估计的个人饮食摄入量进行了比较。家庭购买和个人摄入量之间的Spearman等级相关在饱和脂肪能量百分比的0.54之间(P
Electronic supermarket sales data provide a promising, novel way of estimating nutrient intakes. However, little is known about how these data reflect the nutrients consumed by an individual household member. A cross-sectional survey of 49 primary household shoppers (age [mean standard deviation age] = 48 +/- 14 years; 84% female) from Wellington, New Zealand, was undertaken. Three months of baseline electronic supermarket sales data were compared with individual dietary intakes estimated from four random 24-hour dietary recalls collected during the same 3-month period. Spearman rank correlations between household purchases and individual intakes ranged from 0.54 for percentage of energy from saturated fat (P
