BACKGROUND/AIMS: Vegetarian and vegan diets are effective in preventing and treating several chronic diseases. However, their acceptability outside a clinical trial setting has not been extensively studied. The aim of this study was to determine the acceptability of a worksite vegan nutrition program and its effects on health-related quality of life and work productivity.
Employees of a major insurance corporation with a body mass index > or =25 kg/m(2) and/or a previous diagnosis of type 2 diabetes received either weekly group instruction on a low-fat vegan diet (n = 68) or received no diet instruction (n = 45) for 22 weeks.
The vegan group reported improvements in general health (p = 0.002), physical functioning (p = 0.001), mental health (p = 0.03), vitality (p = 0.004), and overall diet satisfaction (p < 0.001) compared with the control group. The vegan group also reported a decrease in food costs (p = 0.003), and increased difficulty finding foods when eating out (p = 0.04) compared with the control group. The vegan group reported a 40-46% decrease in health-related productivity impairments at work (p = 0.03) and in regular daily activities (p = 0.004).
A worksite vegan nutrition program is well-accepted and can be implemented by employers to improve the health, quality of life, and work productivity of employees.
背景/目的：素食和纯素饮食在预防和治疗多种慢性疾病方面非常有效。然而，它们在临床试验环境之外的可接受性尚未得到广泛研究。本研究的目的是确定工作场所纯素营养计划的可接受性及其对健康相关生活质量和工作生产力的影响。
BMI≥25kg/m²和/或以前被诊断患有 2 型糖尿病的一家大型保险公司的员工接受每周一次的低脂纯素饮食小组指导（n=68）或不接受饮食指导（n=45），为期 22 周。
与对照组相比，纯素组报告称一般健康状况（p=0.002）、身体机能（p=0.001）、心理健康（p=0.03）、活力（p=0.004）和整体饮食满意度（p<0.001）得到改善。与对照组相比，纯素组还报告称食物成本降低（p=0.003），外出就餐时寻找食物的难度增加（p=0.04）。与对照组相比，纯素组报告称与健康相关的工作生产力障碍减少了 40-46%（p=0.03）和日常活动减少（p=0.004）。
工作场所纯素营养计划是可以接受的，可以由雇主实施，以提高员工的健康、生活质量和工作生产力。
