Abstract

【目的】幼児の偏食の改善に向け,幼稚園における野菜栽培の有効性を明らかにする。<br>【方法】北海道某市内5幼稚園に通う年少児379人を対象に,野菜栽培活動を実施する3園(241人)を実施群,実施しない2園(138人)を非実施群として,10か月間の縦断調査を実施した。栽培野菜はトマトであり,栽培前,収穫後,収穫後6か月(フォローアップ)の3時点において,母親が無記名自記式質問紙に回答した。主要評価項目として偏食,副次評価項目としてトマトに対する嗜好,食に対する興味・関心を設定し,各群において経時変化を観察するとともに,収穫後およびフォローアップの各時点において,偏食を改善した者の割合の群間比較を行った。<br>【結果】実施群では,偏食しない幼児が栽培前に比べて収穫後,フォローアップにおいて有意に増加した一方,非実施群では有意な変化は見られなかった。また,フォローアップにおいて実施群は非実施群よりも偏食を改善した幼児の割合が有意に高かった。さらに,実施群ではトマトが好きな幼児,「野菜について知っていることを楽しそうに話す」幼児,「食べ物を残すことは『もったいない』という」幼児が栽培前に比べて収穫後やフォローアップにおいて有意に増加した。一方,非実施群ではいずれの項目も有意な変化はみられなかった。<br>【結論】幼稚園におけるトマトを用いた野菜栽培は,幼児の偏食に良い影響をもたらす可能性が示唆された。

<b>Objective:</b> This study aimed to investigate the effectiveness of a vegetable growing activity in a kindergarten in improving picky eating habits among preschoolers.<br><b>Methods:</b> This 10-month longitudinal study was conducted in five kindergartens in Hokkaido. Three kindergartens participated in the vegetable growing activity (241 preschoolers; experimental group), while two did not (138 preschoolers; control group). Tomatoes were cultivated. The preschoolers’ mothers provided ratings on a questionnaire before cultivation, after harvesting and six months after harvesting (follow-up). The main outcome investigated was picky eating habits; secondary outcomes were preference for tomato and interest in food and eating. In each group, changes in the answers to these questions were observed, and between-group comparisons were performed on the percentage of preschoolers who had improved picky eating habits.<br><b>Results:</b> In the experimental group, the percentage of picky eaters decreased significantly after harvesting and follow-up. However, in the control group, the percentage of picky eaters did not change significantly. After harvesting and follow-up, the percentage of preschoolers in the experimental group whose picky eating habits had improved was significantly higher than that of preschoolers in the control group. Furthermore, in the experimental group, the percentage of preschoolers who liked tomatoes, who talked to their mothers happily about vegetables, and who expressed regret for wasting food increased significantly after harvesting or follow-up. However, in the control group, these percentages did not change significantly.<br><b>Conclusion:</b> Activities involving growing vegetables such as tomatoes in kindergartens may be beneficial for preschoolers with picky eating habits.
