健康类信息是微信平台中最容易引发用户分享行为的重要内容之一，家庭传播过程当中，沟通模式是对于孩子发挥自身能动性和主动性，以及积极做家庭中的“沟通员”的重要影响因素，也会影响子代对亲代进行健康信息的反哺意愿和效能。当下反哺行为成为家庭当中代际关系的一个新特点、新走向。本研究将家庭代际差异纳入健康传播研究，同时也把健康风险信息的传播机理和交互模式，纳入到家庭视域中，通过信息反哺促进代际共生的持续。在当下健康信息传播中，风险类信息框架分为风险寻求、风险中立和风险规避三种基本类型；传播参与了家庭在话语中共同建构、协商和合法化的核心过程。最后，我们聚焦家庭情境中的信息流通和关系网络，如何促成两代人或者多代人之间信息的反哺，在一定程度上，观照当下家庭文化和家风建设，以及后喻文化如何在代际沟通起到缓和与弥合鸿沟的作用。本文从子代的角度测量健康信息反哺意愿，从亲代的角度测量健康信息反哺效能。本文结合家庭沟通模式理论和信息风险框架建立研究假设，采用在线调查平台见数，并进入家庭线上社交群中观察并收集聊天记录。研究发现，家庭沟通模式对于信息反哺意愿和效能的影响更为显著，“高对话-低服从”的多元型家庭沟通模式下孩子的健康信息反哺意愿最为强烈，反哺效能最高。不过，阅读以“久坐伤身”为主题的信息推送后，无论其采用的信息风险框架类型为风险寻求、风险中立还是风险规避，对于信息反哺的意愿和效能影响并不显著。接受风险中立框架的健康信息之后，子代的健康信息反哺意愿最高，其次是风险规避框架，接受风险寻求框架下的健康信息后反哺意愿最弱。因此，本研究也为未来健康传播研究提供理论与实践启示。家庭内部日积月累形成的沟通模式，在潜移默化之中影响着子代及亲代的健康信息反哺效果，亲代应以发展的眼光看待子代的成长，给予更多的自主性。同时，社交媒体平台及各公众号应转变健康知识的科普方式，面对不同教育层次的用户接受程度，在叙事方式上进行建设性转向，摒弃一味“诉诸恐惧”信息，精准的个性化科普并给出具体应对措施应是未来健康传播的发展方向。

Health information is one of the most important contents in the wechat platform that is most likely to trigger user sharing behavior. In the process of family communication, communication mode is an important factor for children to exert their own initiative and initiative, and actively be a "communicator" in the family, and it will also affect the willingness and effectiveness of children to feed their parents health information. At present, the feeding behavior has become a new characteristic and trend of intergenerational relationship in the family. In this study, family intergenerational differences are included in the study of health communication, and the transmission mechanism and interaction mode of health risk information are also included in the family perspective, so as to promote the continuation of intergenerational symbiosis through information feeding. In the current health information communication, the risk-type information framework is divided into three basic types: risk-seeking, risk-neutral and risk-avoidance. Communication participates in the core process of family co-construction, negotiation and legitimization in discourse. Finally, we focus on the information flow and relationship network in the family context, how to promote the information feeding between two or more generations, to a certain extent, look at the current family culture and family style construction, and how the post-metaphorical culture plays a role in alleviating and bridging the gap in intergenerational communication. This paper measures the willingness of health information to feed back from the perspective of offspring and the effectiveness of health information to feed back from the perspective of parents. Based on the theory of family communication patterns and information risk framework, this paper establishes a research hypothesis, adopts an online survey platform, and enters into family online social groups to observe and collect chat records. The study found that the family communication mode has a more significant impact on the willingness and effectiveness of information feedback, and the multi-type family communication mode of "high dialogue-low obedience" has the strongest willingness and the highest effectiveness of health information feedback. However, after reading the information push with the theme of "sitting for long time is harmful to health", no matter the type of information risk framework adopted by it is risk-seeking, risk-neutral or risk-avoidance, it has no significant impact on the willingness and effectiveness of information feedback. After receiving health information in risk-neutral framework, the progeny had the highest willingness to feed health information, followed by the risk-avoidance framework, and the weakest willingness to feed health information in risk-seeking framework. Therefore, this study also provides theoretical and practical implications for future health communication research. The accumulated communication mode within the family affects the health information feedback effect of the children and parents imperceptibly. The parents should treat the growth of the children from the perspective of development and give them more autonomy. At the same time, social media platforms and public accounts should change the way of popularizing health knowledge. In the face of user acceptance at different levels of education, a constructive shift in narrative mode should be made. Instead of blindly "appealing to fear" information, accurate and personalized popularizing science and giving specific countermeasures should be the development direction of health communication in the future.
