Evidence demonstrates that a gardening and nutrition intervention improves dietary intake in children, although no study has evaluated the effect of this type of intervention on obesity measures. The objective of this pilot study was to develop and test the effects of a 12-week, after-school gardening, nutrition, and cooking program (called LA Sprouts) on dietary intake and obesity risk in Latino fourth- and fifth-grade students in Los Angeles, CA. One hundred four primarily Latino children (mean age 9.8±0.7 years), 52% boys and 59% overweight, completed the program (n=70 controls, n=34 LA Sprouts participants). Weight, height, body mass index, waist circumference, body fat (via bioelectrical impendence), blood pressure, and dietary intake (via food frequency screener) were obtained at baseline and postintervention. LA Sprouts participants received weekly 90-minute, culturally tailored, interactive classes for 12 consecutive weeks during spring 2010 at a nearby community garden, whereas control participants received an abbreviated delayed intervention. Compared to subjects in the control group, LA Sprouts participants had increased dietary fiber intake (+22% vs -12%; P=0.04) and decreased diastolic blood pressure (-5% vs -3%; P=0.04). For the overweight subsample, LA Sprouts participants had a significant change in dietary fiber intake (0% vs -29%; P=0.01), reduction in body mass index (-1% vs +1%; P=0.04) and less weight gain (+1% vs +4%; P=0.03) compared to those in the control group. We conclude that a gardening, nutrition, and cooking intervention is a promising approach to improve dietary intake and attenuate weight gain in Latino children, particularly in those who are overweight.
有证据表明，园艺与营养干预可改善儿童的饮食摄入，不过尚无研究评估此类干预对肥胖指标的影响。这项试点研究的目的是，针对加利福尼亚州洛杉矶市四、五年级的拉丁裔学生，开发并测试一项为期12周的课外园艺、营养及烹饪项目（名为“洛杉矶新芽”）对饮食摄入及肥胖风险的影响。104名主要为拉丁裔的儿童（平均年龄9.8±0.7岁），52%为男孩，59%超重，完成了该项目（70名对照组，34名“洛杉矶新芽”参与者）。在基线和干预后获取体重、身高、体重指数、腰围、体脂（通过生物电阻抗法）、血压以及饮食摄入（通过食物频率筛查）数据。“洛杉矶新芽”参与者于2010年春季在附近的社区花园连续12周每周接受90分钟、符合文化背景定制的互动课程，而对照组参与者接受简化的延迟干预。与对照组受试者相比，“洛杉矶新芽”参与者膳食纤维摄入量增加（+22%对 -12%；P=0.04），舒张压降低（-5%对 -3%；P=0.04）。对于超重子样本，与对照组相比，“洛杉矶新芽”参与者膳食纤维摄入量有显著变化（0%对 -29%；P=0.01），体重指数降低（-1%对 +1%；P=0.04），体重增加较少（+1%对 +4%；P=0.03）。我们得出结论，园艺、营养及烹饪干预是改善拉丁裔儿童饮食摄入并减轻体重增加的一种有前景的方法，尤其是对于超重儿童。
