Background Gardening interventions have been shown to increase fruit and vegetable (F/V) intake among school-aged children. It is unknown whether these effects persist into later adolescence or adulthood, and little is known about whether gardening in later adolescence is related to F/V intake. Objective To identify the relationship between both childhood and recent (within the past 12 months) gardening experiences and current F/V intake among college students. Design/participants A cross-sectional evaluation of 1,121 college freshmen with suboptimal F/V consumption from eight US universities. Main outcome measures Participants completed the National Cancer Institute Fruit and Vegetable Screener and questions about gardening experiences. Respondents were grouped as having gardened or not gardened during childhood and recently. Statistical analyses performed A linear mixed model was used to evaluate the relationship between childhood and recent gardening and current F/V intake. Results Of the student participants, 11% reported gardening only during childhood, 19% reported gardening only recently, 20% reported gardening both as a child and recently, and 49% of students reported never having gardened. Students who gardened both during childhood and recently had a significantly higher mean current intake of F/V compared with students who never gardened (2.5±0.6 vs 1.9±0.5 cup equivalents [CE], respectively; P<0.001). In addition, F/V intake increased with frequency of recent gardening engagement when comparing students who did not garden with those who gardened monthly or weekly (2.1±0.5 CE, 2.4±0.6 CE, and 2.8±0.7 CE, respectively; P<0.001). Conclusions This analysis suggests that the combination of childhood and recent gardening experience is associated with greater current F/V intake among first-year college students not currently meeting national F/V recommendations. In addition, a greater frequency of gardening experience may further enhance this effect.

园艺经验与一年级大学生水果和蔬菜摄入量增加有关：横断面检查

背景 园艺干预已被证明可以增加学龄儿童的水果和蔬菜 (F/V) 摄入量。目前尚不清楚这些影响是否会持续到青春期后期或成年期，而且青春期后期的园艺是否与 F/V 摄入量有关也知之甚少。目的 确定大学生的童年和最近（在过去 12 个月内）园艺经验与当前 F/V 摄入量之间的关系。设计/参与者 对来自美国八所大学的 1,121 名 F/V 消耗不理想的大学新生进行横断面评估。主要结果测量参与者完成了国家癌症研究所水果和蔬菜筛选器以及有关园艺经验的问题。受访者被分组为在童年和最近从事园艺或未园艺。进行的统计分析 使用线性混合模型来评估童年和近期园艺与当前 F/V 摄入量之间的关系。结果 在学生参与者中，11% 的人报告仅在童年时期从事园艺，19% 的人报告最近才从事园艺，20% 的人报告童年和最近都从事园艺工作，49% 的学生报告从未从事过园艺工作。与从不园艺的学生相比，在童年和最近都园艺的学生平均当前摄入的 F/V 显着更高（分别为 2.5±0.6 和 1.9±0.5 杯当量 [CE]；P<0.001）。此外，将不园艺的学生与每月或每周园艺的学生进行比较时，F/V 摄入量随着近期园艺参与频率的增加而增加（分别为 2.1±0.5 CE、2.4±0.6 CE 和 2.8±0.7 CE；P<0.001 ）。结论 该分析表明，童年和近期园艺经验的结合与目前不符合国家 F/V 建议的一年级大学生的 F/V 摄入量增加有关。此外，更频繁的园艺体验可能会进一步增强这种效果。
