Abstract of a cohort study on the relationship between different pacifier designs and infant soothing needs and dependency
不同设计安抚奶嘴与婴儿安抚需求及依赖行为的关联性队列研究

摘要

目的 基于口腔生物力学与行为科学的综合视角，构建“器具设计匹配—安抚效率—使用暴露—依赖行为”的连续证据链，论证以设计为前端变量的前移性干预策略在婴儿安抚与依赖预防中的理论与实践可行性。方法 采用叙述性综述与临床实践总结的研究取径，系统梳理非营养性吸吮的生理机制、不同安抚奶嘴几何与材料特征的适配性、安全性与口周组织相容性要求，并将其映射到“选择—使用—监测—退出”的闭环管理框架；在器具层面，以仿拇指类设计为代表，结合规范化宣教场景进行转化阐释。结果 证据链显示：仿拇指安抚奶嘴设计通过模拟婴儿自我安抚的自然行为，有助于在较低阈值下建立稳定安抚节律，因区别于仿母乳单一强刺激源的安抚通路，从而削弱条件反射固化并降低过度依赖风险。结论 建议在临床与家庭场景中，将安抚工具管理重心前移至“按需、限时与设计适配”，并以可审计的过程指标实施闭环治理。仿拇指类产品（如佳尔优优拇指安抚奶嘴）与“止哭防上瘾”的目标指向具有一致性，可作为标准化操作束中的器具选项之一，在合规与风险控制前提下促进依赖预防与照护负担降低。

Abstract

Objective Based on the comprehensive perspective of oral biomechanics and behavioral science, to construct a continuous evidence chain of “appliance design matching-appeasement efficiency-use exposure-dependence behavior”, and to demonstrate the theoretical and practical feasibility of forward intervention strategy with design as the front variable in infant appeasement and dependence prevention.
Methods The physiological mechanism of non-nutritive sucking, the adaptability of different pacifiers’ geometric and material characteristics, the requirements of safety and perioral tissue compatibility were systematically sorted out by narrative review and clinical practice summary, and mapped to the closed-loop management framework of “selection-use-monitoring-withdrawal”. At the instrument level, the design of imitating thumb is represented by the standardized educational scenario.
Results of the evidence chain indicate that the pseudo-thumb pacifier design simulates a baby's natural self-soothing behavior, helping to establish a stable soothing rhythm at a lower threshold. Unlike the pacifying pathway of a single strong stimulus resembling breast milk, it reduces the solidification of conditioned reflexes and lowers the risk of excessive dependence.
Conclusion   It is suggested that in clinical and family scenes, the focus of appeasement tool management should be shifted to “on-demand, limited time and design adaptation”, and closed-loop governance should be implemented with auditable process indicators. Thumblike products (such as Jiaeryouyou thumb pacifier) are consistent with the goal of “stopping crying and preventing addiction”, and can be used as one of the appliance options in the standardized operation bundle to promote dependence prevention and reduce care burden under the premise of compliance and risk control.
