A statewide cross-sectional study of risk factors for seropositivity for antibody to Borrelia burgdorferi in outdoor workers in New Jersey was performed in September and October 1988. The crude odds ratio associated with exposure to ticks on the primary state job was 2.2 (95% confidence interval (CI) 0.7-9.0). After adjustment for multiple confounding variables with logistic regression, the adjusted occupational tick exposure odds ratio was 5.1 (95% CI 1.1-23.6). Additional analyses revealed that any use of insect repellent or antibiotics may have decreased the risk of Lyme disease in these workers (adjusted odds ratios for not using insect repellent or antibiotics were 2.0 (95% CI 1.0-4.0) and 2.3 (95% CI 0.8-6.7), respectively). These data suggest that Lyme disease is a hazard of outdoor work and that increased recognition of this fact will be necessary to prevent Lyme disease in these workers.
1988年9月和10月，在新泽西州对户外工作者进行了一项全州范围的横断面研究，以调查伯氏疏螺旋体抗体血清阳性的危险因素。在主要州立工作中，与接触蜱虫相关的粗比值比为2.2（95%置信区间（CI）0.7 - 9.0）。在通过逻辑回归对多个混杂变量进行调整后，调整后的职业性蜱虫接触比值比为5.1（95% CI 1.1 - 23.6）。进一步分析表明，使用驱虫剂或抗生素可能降低了这些工作者患莱姆病的风险（未使用驱虫剂或抗生素的调整后比值比分别为2.0（95% CI 1.0 - 4.0）和2.3（95% CI 0.8 - 6.7））。这些数据表明，莱姆病是户外工作的一种危害，并且有必要提高对这一事实的认识，以预防这些工作者感染莱姆病。
