大專生休閒運動習慣與食物選擇及身體功能之相關性初探

Correlation Between Leisure-time Exercise, Dietary Choices, and Physical Function in College Students: A Preliminary Study

目的：探討大專生日常休閒運動習慣與其飲食態度及行為與身體功能之相關性。方法：以橫斷面設計進行初探性研究募集大專生研究對象，透過問卷收集基本資料及飲食態度行為分數，並使用身體組成測量儀分析身體組成與手握力及坐姿體前彎了解身體功能。結果：本研究共招募50名大專生研究對象，年齡中位數21.0歲，其中男性有22名且女性有28名，用餐習慣以每日2餐居多；相關性分析顯示大專生研究對象對每一次外食會全部吃完行為頻率分數與肌肉質量顯著正相關（r = 0.36，p = 0.01），且其選擇非精緻澱粉當作主食的頻率分數與坐姿體前彎距離顯著正相關（r = 0.30，p = 0.03）。結論：對健康飲食行為有較好遵從度之大專生可能有助於身體組成及功能表現。

Purpose: This study aims to explore the correlation between college students' daily leisure-time exercise, dietary attitudes and behaviors, and physical function. Methods: A cross-sectional design was used to conduct a preliminary study to recruit col-lege students as research subjects. Data were collected on subjects’demographics, dietary attitudes and behavior frequency scores through a questionnaire. Body composition was analyzed using a body composition analyzer, while handgrip strength and sit-and-reach tests were used to assess physical function. Results: A total of 50 college students were recruited for this study, with a median age of 21.0 years. Among them, 22 were male and 28 were female. Most participants reported having two meals per day. Correlation analysis showed that the frequency of eating all the food ordered when dining out was positively associated with limb muscle mass index (r = 0.36, p = 0.01), and the frequency of choosing unrefined starches was positively correlated with sit-and-reach performance. (r = 0.30, p = 0.03). Conclusions: College students with better adherence to healthy dietary behaviors may exhibit more favorable body composition and physical function.
