OBJECTIVE
Examine the effect of a multi-component office ergonomics intervention on visual symptom reductions.
METHODS
Office workers were assigned to either a group receiving a highly adjustable chair with office ergonomics training (CWT), a training-only group (TO) or a control group (C). A work environment and health questionnaire was administered 2 and 1 month(s) pre-intervention and 3, 6, and 12 months post-intervention. Multi-level statistical models tested hypotheses.
RESULTS
The CWT intervention lowered daily visual symptoms (p < 0.01) post-intervention. The TO group did not significantly differ from the control group. The CWT group differed significantly from the TO group (p = 0.01) post-intervention.
CONCLUSION
Workers who received a highly adjustable chair and office ergonomics training had reduced visual symptoms and the effect was maintained through twelve months post-intervention. The lack of a training-only group effect supports implementing training in conjunction with the highly adjustable chair to reduce visual symptoms.
目的
研究多组分办公人体工程学干预对视觉症状缓解的影响。
方法
将办公室工作人员分为接受高度可调节座椅和办公人体工程学培训（CWT）的小组、仅接受培训（TO）的小组或对照组（C）。在干预前 2 个月和 1 个月以及干预后 3 个月、6 个月和 12 个月进行工作环境和健康问卷。使用多层次统计模型检验假设。
结果
CWT 干预后每日视觉症状降低（p<0.01）。TO 组与对照组之间没有显著差异。CWT 组与 TO 组在干预后存在显著差异（p=0.01）。
结论
接受高度可调节座椅和办公人体工程学培训的工人视觉症状减轻，且这种效果在干预后 12 个月内保持。仅接受培训的小组没有效果，这支持在实施高度可调节座椅的同时进行培训，以减少视觉症状。
