虽然之前的社交网络研究一直表明同龄人吸烟对自己吸烟的社交影响，但很少有研究研究这种影响如何根据同龄人在社交网络中的结构位置而不同。对这种影响的脆弱性是否会因自我的社会经济地位而不同，也缺乏调查。因此，本研究旨在考察同伴吸烟和自我吸烟之间的关系如何因同伴在自我人际网络中的受欢迎程度和自我的教育程度而不同。我们使用了2017年进行的第三波日本分层、健康、收入和邻里研究(J-SINE)的数据，该研究针对日本大都市地区四个直辖市的中年(32-58岁)居民。通过名称生成器和名称解释器方法收集关于四个亲密节点的特征和行为及其相互关系的信息。对1989名受访者和7956名同龄人的数据进行了评估。将节点的特征向量中心度作为其在EGO个人网络中的受欢迎度指标。我们将自我的吸烟作为一个结果，使用具有稳健标准误差的Logistic回归模型，对每个同龄人的吸烟、每个同龄人的受欢迎程度和自我的教育程度进行回归，以调整自我的年龄、性别、工作状况、婚姻状况、配偶/伴侣的吸烟状况以及同龄人和自我的社会经济背景的相似性。然后，我们将这三个解释变量的三向交互作用项添加到模型中。结果表明，当同伴受欢迎时，同伴的吸烟状况与自我吸烟的相关性更强，但只有在教育程度较低的自我时才会如此。结果表明，社会经济地位不同的吸烟行为的差异可能部分是由于社会经济弱势群体中个人网络对社会影响的敏感度。这项研究提出了一种合理的方法来确定个人社交网络中的同伴影响者，以缩小吸烟的社会经济差距。
Although previous social network studies have consistently shown the social influence of peers' smoking on one's (ego's) smoking, few studies have examined how the influence differs according to peers' structural positions in the network. Investigations are also lacking on whether vulnerability to the influence varies by ego's socioeconomic position. Thus, the present study aimed to examine how the association between peers' smoking and ego's smoking differs by peers' popularity in ego's personal network and ego's educational attainment. We used data from the third-wave Japanese Study on Stratification, Health, Income, and Neighborhood (J-SHINE) conducted in 2017, which targeted middle-aged (32–58-year-old) residents in four municipalities within Japanese metropolitan areas. Information on four close peers' characteristics and behaviors and their mutual relationships was collected by the name generator and name interpreter methods. Data on 1989 respondents and 7956 peers were evaluated. Peers' eigenvector centrality was used as their popularity index in ego's personal network. We set ego's smoking as an outcome, regressed on each peer's smoking, each peer's popularity, and ego's educational attainment adjusting for ego's age, sex, working status, marital status, spouse's/partner's smoking status, as well as similarity in socioeconomic backgrounds between peer and ego, using a logistic regression model with robust standard errors. We then added a three-way interaction term for these three explanatory variables to the model. Results showed that peer's smoking status was related to ego's smoking even more strongly when the peer was popular but only in the case of ego with lower educational attainment. The results suggested that the disparity in smoking behavior across socioeconomic positions may be partly explained by susceptibility to social influence from one's personal network among the socioeconomically vulnerable. This study proposes a plausible method for pinpointing the peer influencer in one's personal social network to close the socioeconomic gap in smoking.
