Food Sensations for Adults is a free four-week nutrition and cooking program that teaches low- to middle-income individuals food literacy. This research aimed to compare demographic characteristics of participants who completed the program's follow-up questionnaire three months after program completion and assess whether food literacy and dietary behaviour changes were improved or maintained. Statistical analysis methods used factor scores of the plan and manage, selection, and preparation domains to examine mean self-reported changes in food literacy. Tertile stratification methods calculated changes in participants who had low, middle, and high end-of-program food literacy scores, and multivariable regression analysis explored the associations. The follow-up results ( = 621) demonstrated a statistically significant factor score increase in plan and manage (3%) and selection (7.2%) domain scores, and a decrease in the preparation score (3.1%), and serves of consumed vegetables (7.9%), but were still significantly higher than at the start of the program. At follow-up, participants with low food literacy at the program end significantly improved their follow-up domain scores for plan and manage (60%) and selection (73.3%), and participants with moderate or high food literacy at the program end maintained their follow-up scores. A food literacy program can support adults to improve and maintain their food literacy behaviours and maintain dietary behaviour change; therefore, strategies to support this continued change must be considered.
成人食物感知是一个为期四周的免费营养和烹饪项目,旨在向中低收入人群教授食物素养。本研究旨在比较完成项目后续问卷调查的参与者的人口统计学特征,评估食物素养和饮食行为变化是否得到改善或维持。采用计划和管理、选择和准备领域的因子得分来检验食物素养自我报告变化的均值,以此作为统计分析方法。使用三分位分层方法计算食物素养得分较低、中、高的参与者的变化情况,并采用多变量回归分析探索关联。随访结果(n=621)表明,计划和管理(3%)和选择(7.2%)领域的因子得分显著增加,而准备领域的因子得分(3.1%)和蔬菜食用份数(7.9%)显著下降,但仍显著高于项目开始时的水平。随访时,项目结束时食物素养较低的参与者在计划和管理(60%)和选择(73.3%)领域的随访得分显著提高,而项目结束时食物素养处于中等或较高水平的参与者则保持了随访得分。食物素养项目可以支持成年人改善和维持他们的食物素养行为,并维持饮食行为的改变;因此,必须考虑支持这种持续变化的策略。
