摘要

摘要:
目的探讨建立健康食堂评价指标体系,为开展健康食堂评定工作提供科学依据。

方法选择32 名专家进行两轮Delphi 专家咨询,根据指标重要性赋值得分,确定健康食堂的评价指标及其权重。

结果 32 名咨询专家的平均工龄为(18.41& #177;8.03)年,两轮的应答率均为100%,权威系数分别为0.85& #177;0.06、0.88& #177;0.06,Kendall 协调系数分别为0.708(χ²=675.773,P< 0.01)、0.853(χ²=818.902,P< 0.01),经卡方检验均具有统计学意义;确定了健康食堂评价一级指标6 项、二级指标25 项,以及各项指标的权重,其中一级指标健全的组织管理、健康的环境、健康的膳食、健康的膳食服务和指导、健康的膳食安全保障、科学的效果评估的平均权重分别为1.55、1.56、2.05、1.91、1.08、1.86。

Results The average length of service of the thirty-two experts was (18.41& #177;8.03) years. The response rates of the two round consultations from the experts were both 100%, and the average coefficients of experts' authorities were 0.85& #177;0.06 and 0.88& #177;0.06, with Kendall coefficients of 0.708 (χ²=675.773, P< 0.01) and 0.853 (χ²=818.902, P< 0.01), respectively. Six first-class indicators and twentyfive second-class indicators were identified. And the weights of the indicators were also established: the average weights of sound organization and management, healthy environment, healthy diet, healthy diet service and guidance, healthy food safety security, and scientific effect evaluation of the first-class indicators were 1.55, 1.56, 2.05, 1.91, 1.08, and 1.86, respectively.
