摘　　要：目的了解学生家长碘营养知识认知情况、补碘意愿,研究其与补碘行为间的作用机制。方法2022年采用整群随机抽样方法选取东台市幼儿园至高中4学段学生家长,使用基于保护动机理论自行设计的调查问卷,对社会人口学、碘营养知识、补碘意愿进行调查,采用多重线性回归分析补碘意愿影响因素,构建结构方程模型分析补碘意愿与补碘行为间的作用机制。结果共收集有效问卷985份,学生家长碘营养知识得分为(5.72±2.16),家长补碘意愿均分为(3.82±0.75),不同文化程度、家庭收入、是否接受过碘营养教育和带孩子检测过碘营养水平的家长碘营养知识得分、补碘意愿均分差异均有统计学意义(P值均<0.05)。多重线性回归分析结果表明,知识得分越高(β=0.123)、家庭收入>20万/年的家长(β=0.159)、曾接受碘营养知识教育(β=-0.143)的家长补碘意愿越强烈。路径分析结果显示,自我效能(β=0.404)、反应效能(β=0.249)意识越强的家长补碘意愿越强,反应成本意识越强的家长补碘意愿越微弱(β=-0.212)。补碘意愿对补碘行为(β=0.880)有正向影响。结论东台市学生家长碘营养知识知晓率低,补碘意愿一般,需加强健康教育,增强居民的反应效能和自我效能,提升补碘意愿。Objective To investigate the awareness of iodine nutrition knowledge and willingness to supplement with iodine,and examine the correlation between willingness to supplement with iodine and iodine supplementation behaviors.Methods Students′parents were sampled using a random cluster sampling method from kindergartens to senior high schools in Dongtai City in 2022,and the socio⁃demographics,iodine nutrition knowledge and willingness to supplement with iodine were investigated using self⁃designed questionnaires based on protection motivation theory.Factors affecting the willingness to supplement with iodine were identified using multiple linear regression analysis,and the correlation between willingness to supplement with iodine and iodine supplementation behaviors was examined using structural equation models.Results A total of 985 valid questionnaires were recovered,and the mean scores for iodine nutrition knowledge and willingness to supplement with iodine were(5.72±2.16)and(3.82±0.75)points among students′parents,respectively.There were significant differences in the scores for iodine nutrition knowledge and willingness to supplement with iodine among students′parents in terms of educational level,family income,receiving iodine nutrition education and detection of iodine nutrition levels(all P values<0.05).In addition,multiple linear regression analysis showed that higher scores of iodine nutrition knowledge(β=0.123),annual family incomes of 200 thousand RMB(β=0.159)and having received iodine nutrition education(β=-0.143)resulted in stronger willingness to supplement with iodine among students′parents.Pathway analysis showed that higher self⁃efficacy(β=0.404)and response efficacy(β=0.249)resulted in stronger willingness to supplement with iodine among students′parents,and higher response costs resulted in lower willingness to supplement with iodine among students′parents(β=-0.212).In addition,the willingness to supplement with iodine posed a positive effect on iodine supplementation beh
