校園園藝活動能提高兒童蔬菜偏好及身體活動量嗎？

過去有部分研究指出校園園藝活動能改善國小生蔬菜攝取量，同時增加兒童身體活動量。台灣國小生普遍存在偏食與活動量不足問題，本研究目的是想了解校園園藝活動的導入能否提高兒童蔬菜偏好及身體活動量。對象為國小中年級學生，共44名（分為種植組與食教組），調查時間為2019年9-12月。研究工具分兩部分，飲食偏好調查採用蔬菜偏好問卷、營養知識問卷及訪談；身體活動量部分採用智慧型手錶測量及觀察法。結果發現，兩組學生的蔬菜偏好都有改善，且種植組後測分數高於食教組。另外，心率結果顯示，園藝活動僅提供兒童1.68%的中度至劇烈身體活動量，未能如過去研究指出的園藝活動能提高身體活動量。

Several previous studies indicated that horticultural activities in the schoolyard can not only improve the vegetable intake of elementary school students, but also increase their physical activities. Taiwanese elementary school students generally have the issues of picky eaters and insufficient physical activities. The purpose of this study is to understand whether the introduction of horticultural activities to schoolyard can improve vegetable preference and physical activity of students. A total of 44 students from 3rd and 4th grade of elementary school (divided into the planting group and the food education group) joined this study from September to December 2019. The survey tools were divided into two parts. Firstly, the dietary preference survey utilized the vegetable preference questionnaire, the nutrition knowledge questionnaire and interviews. Secondly, for the physical activity study, the measurement by smart watch and observation methods were applied. The results showed that both groups had improvement on vegetable preferences and the post-test scores of the planting group were higher than those of the food education group. Based on the heart rate results, horticultural activities can only provide 1.68% of moderate-to-vigorous physical activity in students which is not consistent with the past studies. However, it still can assist to reduce the sedentary time of children in school.
