Abstract:
There is a growing concern about unhealthy eating habits and their impact on public health, underscoring the importance of research to understand its determinants and encourage healthy food habits. Using behavioural economic insights in researching dietary habit offer advantages beyond the scope of observational studies. Therefore, this paper examines impulsivity, self-indulgence, prudence and their associations with an individual\'s eating habits and body mass index (BMI). Data were collected from a sample of 487 Chinese participants. Most participants (88%) had good eating habits based on the Healthy Eating Assessment score. The findings of a logistic regression analysis investigating the determinants of individual dietary behaviour based on participants\' self-rating of their overall dietary habits indicate that consumers who showed temporal impulsivity for favourite food tend to have poorer habits of eating healthy foods. The results of a multiple linear regression examining the factors that influence eating habits from a composite score of the Healthy Eating Assessment indicate that the score is better with temporal impulsivity for healthy food and poor with temporal impulsivity for unhealthy food. Further, the score decreases with impulsivity measured as low self-control. The control variables, age and gender, are also significant. The findings of a linear regression analysis exploring the determinants of BMI and their association with impulsivity, self-indulgence and prudence indicate that individuals with higher impulsivity measured as low self-control are mostly in the higher BMI category. These findings are important for designing and implementing public health initiatives to promote healthier dietary habits.
摘要:
人们越来越关注不健康的饮食习惯及其对公众健康的影响,强调研究的重要性,以了解其决定因素,并鼓励健康的饮食习惯。在研究饮食习惯时使用行为经济学见解提供了超出观察性研究范围的优势。因此,本文研究了冲动性,自我放纵,谨慎及其与个人饮食习惯和体重指数(BMI)的关系。数据来自487名中国参与者的样本。大多数参与者(88%)根据健康饮食评估评分有良好的饮食习惯。根据参与者对整体饮食习惯的自我评估,调查个体饮食行为决定因素的逻辑回归分析结果表明,对喜爱的食物表现出暂时冲动的消费者往往有较差的饮食习惯。从健康饮食评估的综合得分中检查影响饮食习惯的因素的多元线性回归结果表明,健康食物的时间冲动性得分较好,不健康食物的时间冲动性较差。Further,得分随着冲动性的降低而降低,测量为低自制力。控制变量,年龄和性别,也很重要。线性回归分析的发现,探索BMI的决定因素及其与冲动性的关系,自我放纵和谨慎表明,冲动性较高的个体被测量为低自我控制,大多属于较高的BMI类别。这些发现对于设计和实施公共卫生计划以促进更健康的饮食习惯非常重要。
