Publicly funded recreation and sports facilities provide children with access to affordable physical activities, although they often have unhealthy food environments that may increase child obesity risk. This study evaluated the impact of a capacity-building intervention (Healthy Food and Beverage Sales; HFBS) on organizational capacity for providing healthy food environments, health of vending machine products, and food policy development in recreation and sport facilities in British Columbia, Canada.
Twenty-one HFBS communities received training, resources, and technical support to improve their food environment over 8 months in 2009-2010, whereas 23 comparison communities did not. Communities self-reported organizational capacity, food policies, and audited vending machine products at baseline and follow-up. Repeated-measures analysis of variance evaluated intervention impact.
Intervention and comparison communities reported higher organizational capacity at follow-up; however, improvements were greater in HFBS communities (p<0.001). Healthy vending products increased from 11% to 15% (p<0.05), whereas unhealthy products declined from 56% to 46% (p<0.05) in HFBS communities, with no changes in comparison communities. At baseline 10% of HFBS communities reported having a healthy food policy, whereas 48% reported one at follow-up. No comparison communities had food policies.
This is the first large, controlled study to examine the impact of an intervention to improve recreation and sport facility food environments. HFBS communities increased their self-rated capacity to provide healthy foods, healthy vending product offerings, and food policies to a greater extent than comparison communities. Recreation and sport settings are a priority setting for supporting healthy dietary behaviors among children.
由公共资金资助的娱乐和体育设施为儿童提供了参与价格合理的体育活动的机会，尽管这些设施往往存在不健康的食品环境，可能会增加儿童肥胖的风险。本研究评估了一项能力建设干预措施（健康食品和饮料销售；HFBS）对加拿大不列颠哥伦比亚省娱乐和体育设施中提供健康食品环境的组织能力、自动售货机产品健康状况以及食品政策制定的影响。
2009年至2010年期间，21个HFBS社区在8个月内接受了培训、资源和技术支持，以改善其食品环境，而23个对照社区则没有。社区在基线和随访时自行报告组织能力、食品政策，并对自动售货机产品进行审计。重复测量方差分析评估干预效果。
干预社区和对照社区在随访时报告的组织能力更高；然而，HFBS社区的改善更大（p<0.001）。在HFBS社区，健康自动售货产品从11%增加到15%（p<0.05），而不健康产品从56%下降到46%（p<0.05），对照社区则没有变化。基线时，10%的HFBS社区报告有健康食品政策，而随访时这一比例为48%。对照社区没有食品政策。
这是第一项大型对照研究，旨在检验一项改善娱乐和体育设施食品环境的干预措施的效果。与对照社区相比，HFBS社区在提供健康食品、健康自动售货产品供应和食品政策方面的自我评估能力有了更大程度的提高。娱乐和体育场所是支持儿童健康饮食行为的重点场所。
