Farmworkers are at risk of exposure to organophosphate pesticides (OPs). Improvements of knowledge and perceptions about organophosphate (OP) exposure may be of benefit for the reduction in OP exposure.
The purpose of this study was to examine the effectiveness of an educational intervention to improve knowledge and perceptions for reducing OP exposure among Indonesian and South Australian (SA) migrant farmworkers.
This was a quasi-experimental study. The educational intervention used a method of group communication for 30 Indonesian farmworkers and individual communication for seven SA migrant farmworkers. Knowledge and perceptions about OP exposure were measured pre-intervention and 3 months after the intervention.
Unadjusted intervention effects at follow-up showed statistically significantly improved scores of knowledge (both adverse effects of OPs and self-protection from OP exposure), perceived susceptibility, and perceived barriers among Indonesian farmworkers compared with SA migrant farmworkers. Furthermore, these four significant variables in the unadjusted model and the two other variables (perceived severity and perceived benefits) were statistically significant after being adjusted for the level of education and years working as a farmworker. In contrast, knowledge about adverse effects of OPs was the only variable that was statistically significantly improved among SA migrant farmworkers. The results of this study suggests educational interventions using a method of group communication could be more effective than using individual intervention.
These improvements provide starting points to change health behavior of farmworkers, particularly to reduce OP exposure, both at the workplace and at home.
农场工人面临接触有机磷农药的风险。提高对有机磷农药接触的认识和认知可能有助于减少有机磷农药接触。
本研究旨在检验一项教育干预措施的有效性，该措施旨在提高印度尼西亚和南澳大利亚（SA）流动农场工人对减少有机磷农药接触的认识和认知。
这是一项准实验研究。教育干预对30名印度尼西亚农场工人采用小组交流方法，对7名南澳大利亚流动农场工人采用个体交流方法。在干预前和干预后3个月测量对有机磷农药接触的认识和认知。
随访时未经调整的干预效果显示，与南澳大利亚流动农场工人相比，印度尼西亚农场工人在知识（有机磷农药的不良反应和自我保护免受有机磷农药接触）、感知易感性和感知障碍方面的得分在统计学上有显著提高。此外，在对教育水平和农场工人工作年限进行调整后，未经调整模型中的这四个显著变量以及另外两个变量（感知严重性和感知益处）在统计学上具有显著意义。相比之下，有机磷农药不良反应的知识是南澳大利亚流动农场工人中唯一在统计学上有显著提高的变量。本研究结果表明，采用小组交流方法的教育干预可能比采用个体干预更有效。
这些改善为改变农场工人的健康行为提供了起点，特别是在工作场所和家中减少有机磷农药接触。
