To evaluate the impact of activities promoting the consumption of fruit and vegetables (FV) in the workplace.
Intervention study with historical control group conducted in a public company in Rio de Janeiro, Southeastern Brazil, between 2007 and 2009. It consisted of three stages: (a) baseline, which included the characterization of both the company studied and the one responsible for providing meals to the employees, assessment of FV intake by the staff and forming a focus group to identify the determinants of FV consumption and to inform the planning of the intervention; (b) intervention, comprised of an environmental component (company's restaurant) and an educational component (directed at individuals); and (c) post-intervention assessment, which included impressions about changes in the company's restaurant in terms of FV supply, exposure of individuals to the intervention and FV consumption by the employees. The analysis of the association between exposure and outcome indicators was conducted using multiple regression models.
On average, the coverage of educational activities and materials was 63.5%. Most employees perceived positive changes in at least one of the five environmental aspects examined. There was an increase (38%) in FV consumption by employees, which corresponds to 0.66 servings in the meal evaluated (lunch). Significant association between indicators of exposure, (both environmental and educational components) and outcome indicators was observed.
FV consumption increased among employees exposed to an intervention focused on the promotion of these foods in the workplace. The multi-component design of the intervention seems to have contributed to these findings.
评估在工作场所开展促进水果和蔬菜消费活动的影响。
这是在巴西东南部里约热内卢的一家公共公司进行的干预性历史对照研究,于 2007 年至 2009 年开展。研究包括三个阶段:(a)基线,包括对所研究公司和负责为员工提供膳食的公司进行特征描述,评估员工的水果和蔬菜摄入量,并组建一个焦点小组,以确定影响水果和蔬菜消费的因素,并为干预计划提供信息;(b)干预,包括环境部分(公司餐厅)和教育部分(针对个人);(c)干预后评估,包括评估公司餐厅在水果和蔬菜供应方面的变化、个人对干预措施的接触情况以及员工的水果和蔬菜消费情况。使用多回归模型对暴露和结局指标之间的相关性进行分析。
平均而言,教育活动和材料的覆盖率为 63.5%。大多数员工至少对五个环境方面中的一个方面的变化有积极的看法。员工的水果和蔬菜摄入量增加(38%),相当于评估餐(午餐)中增加了 0.66 份。暴露指标(环境和教育两个部分)与结局指标之间存在显著相关性。
在工作场所接触到以促进这些食物消费为重点的干预措施的员工,其水果和蔬菜摄入量增加。干预措施的多组成部分设计似乎促成了这些发现。
