摘要成瘾行为（addictive behaviour）指可导致大脑相关区域出现显著奖赏效应、具有显著成瘾潜力的重复性行为。成瘾行为可导致个体形成病理性的行为模式，继而引起多方面的损害。ICD-11中将该行为模式称为“成瘾行为所致障碍”，将游戏和赌博列为主要的成瘾行为。籍电子信息技术的高速发展，游戏和赌博产品在全球范围内出现了明显的融合趋势，给成瘾医学领域内的公共精神卫生工作带来了新挑战。在此背景下，本文对游戏和赌博的定义、两者的融合趋势和该趋势带来的公共卫生影响及对策进行介绍。

abstractsAddictive behaviour refers to those repetitive behaviours which can lead to typical rewarding effects in related brain regions with great potential to "addictiveness". People engaged in such behaviours may develop mental disorders associated with functional impairment or distress. In ICD-11, video gaming and gambling are two major addictive behaviours. Globally, there has been a trend of the convergence between gaming and gambling, significantly aided by the rapid development of information technology. The trend introduces a new challenge for public health, especially in the sphere of behavioural addiction. Against this background, this article elucidates the definition of gaming and gambling, the convergence, and its public health implications and corresponding countermeasures.
