DESCRIPTION (provided by applicant): The enormity of the problem of childhood obesity in the US requires that effective, innovative prevention and intervention strategies be developed for the future health and success of our Country. Recently, the formation of the first-ever federal task force began to address this childhood obesity epidemic, with one of the key pillars being making healthy foods more affordable and accessible for families, and uses gardening as a primary vehicle to engage the public. However, few well-designed experimental studies exist that rigorously evaluate the impact of garden-based nutrition interventions on obesity and related metabolic disorders specifically in high-risk youth populations. We recently developed and demonstrated that a pilot 12-week after-school gardening/nutrition intervention ("LA Sprouts") in 4th - 5th grade students improved dietary fiber and vegetable intake, increased preference for fruit and vegetable intake, improved cooking and gardening skills, and decreased blood pressure and rate of weight gain in overweight students. However, this pilot study was not a randomized controlled trial, was conducted off-campus at a community garden and included a minimal parental component. Given the paucity of research-based trials supporting the federal initiative, additional studies are warranted. The goal of this project is to extend our LA Sprouts pilot study, and conduct a school-garden-based randomized nutrition and gardening intervention, utilizing lessons on campus during after school hours and family workshops at nearby community gardens on weekends, to improve dietary intake and reduce obesity and related metabolic disorders in Latino children (ages 8-11 years). Two regions, each with two elementary schools (a total of 400 3rd-5th graders, >90% Latino) and a participating community garden will be randomized into either: 1) LA Sprouts (12-week after school gardening/nutrition classes + bi-monthly family workshops; two schools, n=200 students); or 2) Control (Delayed intervention; two schools, n=200 students). This project will assess the effects of the LA Sprouts program on dietary intake and related behaviors, and obesity and related metabolic disorders. We hypothesize that students participating in LA Sprouts will consume more fruits and vegetables, have increased preference, motivation, and self-efficacy to eat fruits and vegetables, and have reduced obesity and metabolic risk factors compared to controls.

描述（由申请人提供）：美国儿童肥胖问题的严重性要求为我国未来的健康和成功制定有效的创新预防和干预策略。最近，成立了有史以来第一个联邦工作组，开始解决这一儿童肥胖流行病，其中一个关键支柱是使健康食品更负担得起，更容易为家庭获得，并使用园艺作为一个主要工具，以吸引公众。然而，很少有精心设计的实验研究存在，严格评估的影响，以花园为基础的营养干预措施对肥胖和相关的代谢紊乱，特别是在高风险的青年人群。我们最近开发并证明，在4 - 5年级学生中进行的为期12周的课后园艺/营养干预（“LA Sprouts”）试验改善了膳食纤维和蔬菜的摄入量，增加了对水果和蔬菜摄入的偏好，提高了烹饪和园艺技能，并降低了超重学生的血压和体重增加率。然而，这项试点研究不是一项随机对照试验，是在校外的一个社区花园进行的，包括最小的父母组成部分。鉴于缺乏支持联邦倡议的基于研究的试验，需要进行更多的研究。 该项目的目标是扩展我们的LA Sprouts试点研究，并进行基于学校花园的随机营养和园艺干预，利用放学后的校园课程和周末附近社区花园的家庭研讨会，以改善饮食摄入量，减少肥胖和相关的代谢紊乱拉丁裔儿童（8-11岁）。两个地区，每个地区有两所小学（共400名3 - 5年级学生，>90%拉丁裔）和一个参与的社区花园，将被随机分为：1）LA Sprouts（12周课后园艺/营养课程+双月家庭研讨会;两所学校，n=200名学生）;或2）对照（延迟干预;两所学校，n=200名学生）。该项目将评估LA Sprouts计划对饮食摄入和相关行为以及肥胖和相关代谢紊乱的影响。我们假设，参加洛杉矶豆芽的学生将消耗更多的水果和蔬菜，增加偏好，动机和自我效能感吃水果和蔬菜，并减少肥胖和代谢危险因素相比，控制。
