The aim of this research was to study the impact of the unitary prevention delegates (UPDs) on the Spanish working environment. To this end, a cross-sectional study was carried out using microdata from the National Survey on Health and Safety Management in Companies (ENGE-2009) with a sample of 5147 work centres. To measure the relationship between the presence of UPD in workplaces with preventive management indicators and damage to health, individual and multiple logistic regression models were carried out, calculating the crude (cOR) and adjusted (aOR) odds ratios by sociodemographic covariates, with their corresponding 95% confidence intervals (95% CI). Ambivalent results were obtained. On the one hand, a positive impact of the UPDs was found, in the management of prevention showing a higher probability of prevention plans being carried out (aOR = 3.97; 95% CI: 3.26–4.83), risk assessments (aOR = 5.96; 95% CI: 4.44–8.01) and preventive actions were planned (aOR = 3.01; 95% CI: 2.55–3.56), as well as 1.56 times less likely to register minor occupational accidents (aOR = 0.64; 95% CI: 0.53–0.76). On the other hand, the presence of the UPDs did not promote the activation of a participatory culture and did not reduce the probability of suffering serious and fatal accidents at work. In conclusion, UPDs need to activate workers’ participation to improve results.

统一预防代表在职业风险预防参与管理中的作用及其对西班牙工作环境中职业事故的影响。


本研究的目的是研究统一预防代表（UPD）对西班牙工作环境的影响。为此，我们利用全国公司健康与安全管理调查 (ENGE-2009) 的微观数据，对 5147 个工作中心进行了一项横断面研究。为了衡量工作场所 UPD 的存在与预防性管理指标与健康损害之间的关系，我们建立了个体和多重逻辑回归模型，通过社会人口统计学协变量计算粗比值比 (cOR) 和调整比值比 (aOR)，及其相应的比值比。 95% 置信区间 (95% CI)。得到了矛盾的结果。一方面，UPD 对预防管理产生了积极影响，显示出执行预防计划的可能性更高（aOR = 3.97；95% CI：3.26–4.83）、风险评估（aOR = 5.96；95% CI：3.26-4.83）。 95% CI：4.44–8.01）并计划采取预防措施（aOR = 3.01；95% CI：2.55–3.56），并且登记轻微职业事故的可能性降低了 1.56 倍（aOR = 0.64；95% CI：0.53– 0.76）。另一方面，UPD的存在并没有促进参与文化的激活，也没有减少在工作中遭受严重和致命事故的可能性。总之，UPD 需要激发工人的参与来改善结果。
