As an important way to translate cardiovascular disease prevention efforts, worksite intervention programs can be used to effectively facilitate healthy food choices, health education, and social support among employees, in a targeted approach to improve health outcomes and physical activity levels of employees. In this study, the effectiveness of a canteen and a behavioral intervention on cardiometabolic risk among prediabetic and prehypertensive employees at two multinational worksites in South Africa will be measured. This two-arm randomized controlled trial (RCT) will be structured to provide a six-week intervention at two multinational companies spread across eight worksites and will include a canteen and behavioral arm (CB) and a canteen only (CO) arm. Participants who are either prediabetic or prehypertensive will complete the baseline assessments, which will include anthropometry, a demographic and lifestyle survey, the global physical activity questionnaire (GPAQ) and the 24 h food recall. Participants will be randomized into the CO and the canteen and CB intervention groups. The CO group will receive six weeks of canteen intervention [changes to enable a healthy food environment], while the CB group will receive six weeks of canteen intervention along with a behavioral intervention. The behavioral intervention will include an intense six-week lifestyle program aligned to the Diabetes Prevention Program (DPP). This study will assess the added benefit of environmental-level changes aimed at lowering cardiometabolic risk in a low-middle-income country (LMIC) and has the potential for scale-up to other worksites in South Africa and globally.
作为心血管疾病预防工作的一种重要方式，工作场所干预项目可用于有效促进员工选择健康食品、接受健康教育并获得社会支持，以一种有针对性的方式改善员工的健康状况和身体活动水平。在本研究中，将对南非两家跨国企业中处于糖尿病前期和高血压前期的员工，评估食堂干预和行为干预对心血管代谢风险的有效性。这项双臂随机对照试验（RCT）将在分布于八个工作地点的两家跨国公司开展为期六周的干预，包括食堂与行为干预组（CB）和仅食堂干预组（CO）。患有糖尿病前期或高血压前期的参与者将完成基线评估，包括人体测量、人口统计学和生活方式调查、全球身体活动问卷（GPAQ）以及24小时食物回顾。参与者将被随机分为CO组以及食堂与CB干预组。CO组将接受为期六周的食堂干预[做出改变以营造健康的食物环境]，而CB组将在接受六周食堂干预的同时接受行为干预。行为干预将包括一项与糖尿病预防计划（DPP）一致的为期六周的强化生活方式项目。本研究将评估在低收入和中等收入国家（LMIC）进行环境层面改变以降低心血管代谢风险的额外益处，并且有可能推广至南非及全球的其他工作场所。
