Time spent in meal preparation may be indicative of the healthfulness of meals and therefore with weight status. The purpose of this study was to examine the association between amount of time spent preparing meals and meal food group and nutrient content by meal occasion (breakfast, lunch, and dinner) among 1036 midlife women. Participants completed a 1-day food record and eating occasion questionnaires for each meal occasion. ANCOVA was used to identify possible associations. Approximately half of the participants reported spending <5 min preparing breakfast and lunch, and <20 min preparing dinner. Less time spent preparing breakfast was associated with lower energy and fat intakes (p<0.0001), while less time spent preparing lunch and dinner was associated with lower vegetable and sodium intakes (p<0.0001). There were no apparent differences in the association between time spent preparing meals and meal content by weight status. Nutrition education should encourage home meal preparation while stressing the selection of healthier options. The differing associations by meal occasion suggest that interventions should be tailored according to meal type.
用于准备膳食的时间可能反映了膳食的健康程度,进而与体重状况有关。本研究的目的是在 1036 名中年女性中,通过就餐时间(早餐、午餐和晚餐),检验用于准备膳食的时间量与膳食食物组和营养成分之间的关系。参与者完成了 1 天的食物记录和每个就餐时间的就餐问卷。采用协方差分析(ANCOVA)来确定可能的关联。大约一半的参与者报告用于准备早餐和午餐的时间<5 分钟,用于准备晚餐的时间<20 分钟。准备早餐的时间越少,与能量和脂肪摄入越低有关(p<0.0001),而准备午餐和晚餐的时间越少,与蔬菜和钠摄入越低有关(p<0.0001)。用于准备膳食的时间与体重状况与膳食内容之间的关联没有明显差异。营养教育应鼓励在家准备膳食,同时强调选择更健康的选择。根据就餐类型的不同,干预措施应根据就餐类型进行调整。
