BACKGROUND
Consumption of a high quantity and wide variety of vegetables is currently recommended for health. Dietary variety can be low, however, particularly for older adults. This study investigated the affective factors associated with the quantity and variety of vegetables consumed by older adults in France, Italy and the UK.
METHODS
Adults aged 65 years plus completed questionnaires on self-reported vegetable intake (quantity and variety), liking for vegetables, attitudes towards intake, and demographic variables.
RESULTS
In 497 older adults (France, = 187, Italy, = 152, UK, = 158), higher quantities of vegetables consumed were associated with a higher age, affluence score and liking for vegetables, and a lower importance in consumption of familiarity (smallest β = 0.11, = 0.03). Greater variety was associated with a higher liking and importance of health benefits, and a lower importance of familiarity (smallest β = -0.11, < 0.01). Higher quantity and variety combined (quantity × variety) was associated with a higher age, liking and importance of health benefits, and a lower importance of familiarity (smallest β = 0.14, = 0.02). Country-specific effects were also found (smallest β = 0.20, < 0.01).
CONCLUSIONS
These findings demonstrate a role for liking and a lower concern for eating familiar foods in vegetable consumption, and a particular role for concern for health benefits in the consumption of a greater variety of vegetables.
背景
目前建议人们多吃各种蔬菜以保持健康。然而，老年人的饮食可能种类单一。本研究调查了法国、意大利和英国老年人蔬菜摄入量和种类的相关影响因素。
方法
年龄在 65 岁及以上的成年人完成了关于蔬菜摄入量（数量和种类）、对蔬菜的喜爱程度、对摄入量的态度以及人口统计学变量的自我报告问卷。
结果
在 497 名老年人（法国， = 187，意大利， = 152，英国， = 158）中，蔬菜摄入量较高与年龄较大、较富裕的评分、对蔬菜的喜爱程度较高以及对消费熟悉度的重视程度较低有关（最小 β = 0.11， = 0.03）。种类更多与更高的喜爱度和健康益处的重要性以及熟悉度的重要性较低有关（最小 β = -0.11， < 0.01）。较高的数量和种类相结合（数量×种类）与年龄较大、喜爱度和健康益处的重要性以及对熟悉度的重视程度较低有关（最小 β = 0.14， = 0.02）。还发现了国家特定的影响（最小 β = 0.20， < 0.01）。
结论
这些发现表明，喜爱和对食用熟悉食物的关注程度较低在蔬菜摄入量中起着作用，而对健康益处的关注在食用更多种类的蔬菜方面起着特殊作用。
