Workplace nutrition has been identified as a priority setting that can significantly reduce cardiovascular diseases (CVD) risk factors. This study was conducted as a part of the workplace education program to improve nutritional practices and cardiometabolic status in industrial personnel.
The present research was a randomized controlled field trial conducted on employees of a regional petrochemical company. The health-related priorities of the program were defined and addressed in the study in which 104 employees with dyslipidemia were randomly divided into two groups of education and control. Data were collected pre- and post-intervention, using valid and reliable multi-session questionnaires on demographic data, nutritional knowledge, and nutritional intake. Anthropometric measures, serum FBS, HbA1C, hs-CRP and homocysteine (Hcy) were assessed in both groups. In the education group, the nutrition program included five educational workshops about healthy nutrition and regular exercise along with educational messages over a 3-month period. The controls did not receive any education during the study.
There were no statistically significant differences between the two groups regarding the baseline variables. The education group significantly improved their nutritional knowledge ( < 0.001), dietary intakes ( < 0.005), serum FBS (p < 0.001) and Hcy levels (p < 0.001) and anthropometric indices.
Workplace nutrition education programs can improve knowledge and reduce important CVD risk factors.
工作场所营养已被确定为一个优先事项，可显著降低心血管疾病（CVD）风险因素。本研究作为工作场所教育计划的一部分进行，旨在改善产业人员的营养习惯和心脏代谢状况。
本研究是对一家地区石化公司员工进行的随机对照现场试验。该计划与健康相关的优先事项在研究中得到了明确和解决，其中104名血脂异常员工被随机分为教育组和对照组。在干预前后收集数据，使用关于人口统计学数据、营养知识和营养摄入的有效且可靠的多时段问卷。对两组进行人体测量、血清空腹血糖（FBS）、糖化血红蛋白（HbA1C）、高敏C反应蛋白（hs-CRP）和同型半胱氨酸（Hcy）评估。在教育组中，营养计划包括为期3个月的五次关于健康营养和定期锻炼的教育研讨会以及教育信息。对照组在研究期间未接受任何教育。
两组在基线变量方面无统计学显著差异。教育组显著提高了他们的营养知识（<0.001）、饮食摄入量（<0.005）、血清FBS（p<0.001）和Hcy水平（p<0.001）以及人体测量指标。
工作场所营养教育计划可以提高知识并降低重要的心血管疾病风险因素。
