This study explored how mothers grouped into clusters according to multiple psychographic food decision influencers and how the clusters differed in nutrient intake and nutrient content of their household food supply. Mothers (n = 201) completed a survey assessing basic demographic characteristics, food shopping and meal preparation activities, self and spouse employment, exposure to formal food or nutrition education, education level and occupation, weight status, nutrition and food preparation knowledge and skill, family member health and nutrition status, food decision influencer constructs, and dietary intake. In addition, an in-home inventory of 100 participants' household food supplies was conducted. Four distinct clusters presented when 26 psychographic food choice influencers were evaluated. These clusters appear to be valid and robust classifications of mothers in that they discriminated well on the psychographic variables used to construct the clusters as well as numerous other variables not used in the cluster analysis. In addition, the clusters appear to transcend demographic variables that often segment audiences (eg, race, mother's age, socioeconomic status), thereby adding a new dimension to the way in which this audience can be characterized. Furthermore, psychographically defined clusters predicted dietary quality. This study demonstrates that mothers are not a homogenous group and need to have their unique characteristics taken into consideration when designing strategies to promote health. These results can help health practitioners better understand factors affecting food decisions and tailor interventions to better meet the needs of mothers.
本研究探讨了母亲们如何根据多个心理层面的食物决策影响因素被聚类,以及这些聚类在营养摄入和家庭食物供应的营养成分方面有何差异。母亲们(n = 201)完成了一项调查,评估基本人口统计学特征、食品购物和 meal preparation 活动、自身及配偶的就业情况、接受正规食品或营养教育的情况、教育水平和职业、体重状况、营养和食物制备知识与技能、家庭成员的健康和营养状况、食物决策影响因素结构以及饮食摄入量。此外,还对100名参与者的家庭食物供应进行了家庭库存盘点。在对26个心理层面的食物选择影响因素进行评估时,出现了四个不同的聚类。这些聚类似乎是对母亲们有效的、可靠的分类,因为它们在用于构建聚类的心理层面变量以及聚类分析中未使用的许多其他变量上都有很好的区分度。此外,这些聚类似乎超越了通常用于划分受众的人口统计学变量(如种族、母亲年龄、社会经济地位),从而为刻画这一受众群体的方式增添了一个新维度。此外,从心理层面定义的聚类预测了饮食质量。本研究表明,母亲们不是一个同质化的群体,在设计促进健康的策略时需要考虑她们的独特特征。这些结果可以帮助健康从业者更好地理解影响食物决策的因素,并调整干预措施以更好地满足母亲们的需求。
