The study objective was to quantify interpretations of the term "balanced meals" used in food security status assessments. Telephone interviews included 77 charitable food recipients in Hawaiì. After participants first responded to the question of whether they could afford to eat balanced meals, they next defined what a "balanced meal" meant. Qualitative responses were categorized into common themes. Forty-one (53%) indicated that a balanced meal consisted of at least three food groups.Thirty-one (40%) indicated something other than three food groups; five (6%) had no idea what a "balanced meal" meant. The findings question the validity and reliability of responses to "balanced meal" food security indicators in Hawaiì.
该研究的目的是量化在食品安全状况评估中使用的“均衡膳食”一词的解读。电话访谈涵盖了夏威夷的77名慈善食品受助者。在参与者首先回答他们是否能够负担得起均衡膳食的问题后,他们接着定义了“均衡膳食”的含义。定性回答被归类为共同主题。41人(53%)表示一顿均衡膳食至少由三个食物类别组成。31人(40%)表示是三个食物类别以外的情况;5人(6%)不知道“均衡膳食”是什么意思。这些研究结果对夏威夷“均衡膳食”食品安全指标的回答的有效性和可靠性提出了质疑。
