Occupational stress is increasing in Western societies and the impact is significant at a personal, organisational and community level. The present study examined for the first time the efficacy of 3 months administration of two forms of high dose vitamin B complex on mood and psychological strain associated with chronic work stress.
Sixty participants completed the 3-month, double-blind, randomised, placebo-controlled trial in which personality, work demands, mood, anxiety and strain were assessed.
After individual differences in personality and work demands were statistically controlled, the vitamin B complex treatment groups reported significantly lower personal strain and a reduction in confusion and depressed/dejected mood after 12 weeks. There were no treatment-related changes in other measures of mood and anxiety.
The results of the study are consistent with two previous studies examining multivitamin supplementation and personal (non-work) feelings of strain and suggestive of significant decreases in the experience of workplace stress after 90 day supplementation of a B multivitamin.
Given the direct and indirect costs of workplace stress, these findings point to the utility of a cost-effective treatment for the mood and psychological strain effects of occupational stress. These findings may have important personal health, organisational and societal outcomes given the rising cost and incidence of workplace stress.
在西方社会，职业压力不断增加，其影响在个人、组织和社区层面都很显著。本研究首次考察了连续3个月服用两种高剂量复合维生素B对与慢性工作压力相关的情绪和心理紧张的疗效。
60名参与者完成了一项为期3个月的双盲随机安慰剂对照试验，试验中对性格、工作要求、情绪、焦虑和紧张程度进行了评估。
在对性格和工作要求的个体差异进行统计学控制后，复合维生素B治疗组在12周后报告个人紧张程度显著降低，困惑以及沮丧/低落情绪有所减轻。情绪和焦虑的其他测量指标未出现与治疗相关的变化。
本研究结果与之前两项关于补充多种维生素与个人（非工作）紧张感的研究一致，表明补充复合维生素B 90天后工作压力体验显著降低。
鉴于工作场所压力的直接和间接成本，这些发现表明了一种具有成本效益的治疗方法对职业压力引起的情绪和心理紧张效应的效用。考虑到工作场所压力的成本和发生率不断上升，这些发现可能会产生重要的个人健康、组织和社会成果。
