摘　　要：目的通过评价浦东某造船企业员工膳食模式,为探讨改善企业员工膳食模式的方法提供依据。方法在该企业根据进餐食堂不同抽取2个工作组共843人,随机分为干预组和对照组,对干预组开展为期6个月的营养干预,用DQI法对干预效果进行评估。结果营养干预后,干预组与对照组比较,除蛋类和酒膳食质量指数(DQI)均值外,其余元素DQI均值干预前为负值的上升,为正值的下降,且变化幅度差异有统计学意义;负端分(DQI-LB)均值升高,正端分(DQI-HB)和质量距(DQI-DIS)均值降低,变化幅度差异有统计学意义;模式A、B人数比例高于对照组,模式E、F、G、H人数比例低于对照组,且差异有统计学意义,即营养干预既改善了摄入不足又改善了摄入过量,优化了企业员工的膳食模式。结论 DQI方法能改善企业员工膳食结构,优化膳食模式。[ Objective] To evaluate dietary patterns of employees in a shipbuilding enterprise of Pudong New Area, and provide sci entific evidence for dietary quality promotion.
