To identify key predictors of fast-food consumption from a range of demographic, attitudinal, personality and lifestyle variables.
We analysed data from a nationwide survey (n = 20 527) conducted in Australia by Nielsen Media Research. Items assessing frequency of fast-food consumption at (1) eat in and (2) take away were regressed onto 12 demographic, seven media consumption, and 23 psychological and lifestyle variables, the latter derived from factor analysis of responses to 107 attitudinal and behavioural items.
Stepwise multiple regression analyses explained 29.6% of the variance for frequency of take-away and 9.6% of the variance for frequency of eat-in consumption of fast foods. Predictors of more frequent consumption of fast food at take away (and, to a lesser extent, eat in) included lower age - especially under 45 years, relative indifference to health consequences of behaviour, greater household income, more exposure to advertising, greater receptiveness to advertising, lesser allocation of time for eating, and greater allocation of time to home entertainment. There were no effects for occupational status or education level.
The effects for age suggest that fast-food take-away consumption is associated with a general cultural shift in eating practices; individual differences in attitudinal and lifestyle characteristics constitute additional, cumulative, predictive factors. The role of advertising and the reasons for the lesser explanatory value of the eat-in models are important targets for further research.
从一系列人口统计学、态度、个性和生活方式变量中确定快餐消费的关键预测因素。
我们分析了尼尔森媒体研究公司在澳大利亚进行的一项全国性调查(n = 20527)的数据。将评估在(1)店内就餐和(2)外带时快餐消费频率的项目,对12个人口统计学变量、7个媒体消费变量以及23个心理和生活方式变量进行回归分析,后者源自对107个态度和行为项目的回答进行的因子分析。
逐步多元回归分析解释了外带快餐消费频率方差的29.6%以及店内就餐快餐消费频率方差的9.6%。外带(以及在较小程度上的店内就餐)快餐消费频率较高的预测因素包括年龄较小——尤其是45岁以下、对行为的健康后果相对漠不关心、家庭收入较高接触广告较多、对广告的接受度较高、用餐时间分配较少以及家庭娱乐时间分配较多。职业状况或教育水平没有影响。
年龄方面的影响表明,外带快餐消费与饮食行为的总体文化转变有关;态度和生活方式特征的个体差异构成了额外的、累积的预测因素。广告的作用以及店内就餐模型解释力较低的原因是进一步研究的重要目标。
