Children are disproportionately affected by climate change while evidence regarding their adaptive behavior and relevant influencing factors is limited.
We attempted to investigate health-related adaptive behavior towards climate change for primary school children in China and explore potential influencing factors.
We conducted a survey of 8322 primary school children in 12 cities across China. Knowledge, attitude, risk perception, and adaptive behavior scores for children were collected using a designed questionnaire. Weather exposures of cities were collected from 2014 to 2018. We applied a multiple linear regression and mixed-effect regression to assess the influencing factors of adaptive behavior. We also used the structural equation model (SEM) to validate the theoretical framework of adaptive behavior.
Most children (76.1%) were aware of climate change. They mainly get information from television, smartphones, and the Internet. A 1 score increase in knowledge, attitude, and risk perception was associated with 0.210, 0.386, and 0.160 increase in adaptive behavior scores, respectively. Females and children having air conditioners or heating systems at home were positively associated with adaptive behavior. Exposure to cold and rainstorms increased the adaptive behavior scores, while heat exposure had the opposite effects. The SEM showed that knowledge was positively associated with attitude and risk perception. Knowledge, attitude, and risk perception corresponded to 31.6%, 22.8%, and 26.1% changes of adaptive behavior, respectively.

儿童受气候变化的影响不成比例，而有关他们适应行为及相关影响因素的证据有限。
我们试图调查中国小学生对气候变化的健康相关适应行为，并探讨潜在的影响因素。
我们对中国 12 个城市的 8322 名小学生进行了调查。使用设计好的问卷收集了儿童的知识、态度、风险感知和适应行为得分。从 2014 年到 2018 年收集了城市的天气暴露情况。我们应用多元线性回归和混合效应回归来评估适应行为的影响因素。我们还使用结构方程模型（SEM）来验证适应行为的理论框架。
大多数儿童（76.1%）意识到了气候变化。他们主要从电视、智能手机和互联网获取信息。知识、态度和风险感知每增加 1 分，适应行为得分分别增加 0.210、0.386 和 0.160。女性和家中有空调或暖气系统的儿童与适应行为呈正相关。暴露于寒冷和暴雨会增加适应行为得分，而暴露于高温则会产生相反的影响。SEM 显示，知识与态度和风险感知呈正相关。知识、态度和风险感知分别对应于适应行为的 31.6%、22.8%和 26.1%的变化。
中国大多数小学生都意识到了气候变化。知识、态度、风险感知、寒冷和暴雨暴露与对气候变化的健康相关适应行为呈正相关。
