臺灣大學生蔬果攝取改變階段與蔬果飲食頻率之研究－－跨理論模式之應用

Stages of Change and Food Frequency for Fruit and Vegetable Intake among College Students in Taiwan: An Application of the Transtheoretical Model

本研究目的在瞭解台灣地區大學生的蔬果攝取改變階段及飲食頻率，並探討其與背景變項及跨理論模式變項間的關係。採橫斷式問卷調查，樣本為來自30所大學校院的1051位學生。研究結果發現樣本在蔬菜及水果攝取改變階段的分佈皆以無意圖期及準備期佔多數，行動期及維持期人數較少。蔬菜、水果攝取頻率為平均每日2.16次、0.92次。蔬菜／水果攝取改變階段不同，攝取頻率呈顯著差異，處於較高改變階段者，有較高的攝取頻率。處於較高蔬菜／水果攝取改變階段者，其自我效能、決策權衡整體變項及個別變項的得分均有愈高的趨勢。研究結果支持衛生教育可依目標對象所處的蔬果攝取改變階段設計合適的介入方案。

The purpose of this study was to understand the stages of change and food frequencies for fruit and vegetable intake among college students in Taiwan. Associations were examined between stages of change, food frequencies, and demographic and psychosocial factors. We used a cross-sectional questionnaire design. A sample of 1051 students enrolled in 30 colleges or universities completed a questionnaire. The results revealed that most subjects were in the precontemplation and preparation stages, and a relatively small percentage of students were in the action and maintenance stages. The average daily fruit and vegetable consumption frequencies were 0.92 and 2.16 times. Fruit/vegetable consumption frequencies were positively associated with more advanced stages of change. There was an overall stage effect on self-efficacy and decisional balance, and significant univariate effects for these two variables. The findings of this study imply a utility for the design of stage-tailored interventions for promoting college students' fruit and vegetable intake.
