This study was designed to evaluate the effectiveness of a new health promotion model for lone workers.
A single group pre- or posttest design was used to evaluate intervention effectiveness for reducing body weight and increasing healthful and safe behaviors. Truck drivers (n = 29) from four companies participated in a 6-month intervention involving a weight loss and safe driving competition, computer-based training, and motivational interviewing.
Objectively measured body weight reduced by 7.8 lbs (DeltaSD = 11.5, Deltad = 0.68, P = 0.005), and survey measures showed significant reductions in dietary fat and sugar consumption. An objective measure of safe driving also showed significant improvement, and increases in exercise motivational stage and walking fitness approached significance.
Results suggest that the new intervention model is substantially more engaging and effective with truck drivers than previous education-based tactics.
本研究旨在评估一种新的针对单身员工的健康促进模式的有效性。
采用单组前后测设计评估干预措施对降低体重和增加健康安全行为的效果。来自四家公司的 29 名卡车司机参加了一项为期 6 个月的干预计划，其中包括减肥和安全驾驶比赛、基于计算机的培训和动机访谈。
体重的客观测量值下降了 7.8 磅（DeltaSD = 11.5，Deltad = 0.68，P = 0.005），调查测量显示饮食中脂肪和糖的摄入量显著减少。安全驾驶的客观测量也显示出显著改善，运动动机阶段和步行健身的增加也接近显著。
结果表明，与以往基于教育的策略相比，新的干预模式对卡车司机更具吸引力和有效性。
