摘要
目的调查以幼儿园为基础的教职工及看护人营养知识干预效果及其成本-效果,为教师及儿童看护人的营养知识干预策略的制定提供参考。方法将2018—2021年纳入湘西自治州营养改善试点项目评估的26所幼儿园(干预组和对照组各13所)教职工及部分儿童看护人作为研究对象。干预组以专家讲座培训为主要形式开展为期3年的营养知识干预,对照组不进行干预。干预前后利用相同问卷收集营养知识得分情况,并通过财务记录表统计干预成本数据,评价干预效果及成本-效果。结果干预后干预组幼儿园教职工的营养知识得分为(54.22±3.23)分,高于干预前自身的(46.27±14.96)分(P<0.05),以及对照组干预前后的(52.53±16.68)分和(47.56±15.07)分。干预后干预组儿童看护人的营养知识得分为(58.13±4.23)分,高于干预前自身的(52.82±3.23)分(P<0.05),以及对照组干预前后的(46.27±4.28)分和(50.52±5.73)分。营养知识干预可提高幼儿园教职工营养知识得分(β=12.95,P<0.05),但对儿童看护人营养知识得分的影响差异无统计学意义(β=0.99,P>0.05),面向两者的人均干预成本分别为2957.58元、43.31元,其中幼儿园教职工接受营养知识干预的成本-效果比为1∶228.38。结论湘西自治州营养改善试点项目中的营养知识干预可提升幼儿园教职工的营养知识水平,具有显著的成本效果,但未能有效提升儿童看护人的营养知识水平。
Objective To analyze the effects and cost-effectiveness of kindergarten-based nutrition knowledge intervention among staffs and caregivers,and to provide a reference for nutrition knowledge intervention strategy development on teachers and caregivers of children.Methods The subjects were the staffs and guardians from 26 kindergartens(13 for intervention group and 13 for control group)that were already included in the Nutrition Improvement Pilot Project of Xiangxi Autonomous Prefecture.The intervention group received a 3-year nutrition knowledge intervention,primarily in the form of expert lectures and training,while the control group did not receive any intervention.Nutrition knowledge scores were collected using the same questionnaire before and after the intervention,and the cost of the intervention was calculated by analyzing financial records.The effect and cost-effectiveness of the intervention were evaluated based on these data.Results The nutritional knowledge score of kindergarten teachers in the intervention group after the intervention was(54.22±3.23)points,which was higher than their pre-intervention score of(46.27±14.96,P<0.05),as well as the pre-intervention score(52.53±16.68)and post-intervention score(47.56±15.07)in the control group.The nutritional knowledge score of the childcare providers in the intervention group after the intervention was(58.13±4.23)points,which was higher than their pre-intervention score(52.82±3.23,P<0.05),as well as the pre-intervention score(46.27±4.28)and post-intervention score(50.52±5.73)in the control group.The nutrition knowledge intervention significantly improved kindergarten staffs′nutrition knowledge scores(β=12.95,P<0.05),but the effect on child caregiver nutrition knowledge scores was not statistically significant(β=0.99,P>0.05).The per capita intervention costs oriented to the two were￥2957.58 and￥43.31,respectively.The cost-effectiveness ratio of the nutrition knowledge intervention for kindergarten staff was 1∶228.38.Conclusion Nutrition knowledge intervention in Xiangxi Autonomous Prefecture Nutrition Improvement Pilot Project can improve the nutrition knowledge of kindergarten staffs and had significant cost-effectiveness,but were not effective in improving the nutrition knowledge of child caregivers.
