Social deprivation is a known determinant of health and related behaviors. Many studies have linked socioeconomic factors to secondhand smoke (SHS) exposure. However, no studies have examined the relationship between social deprivation and SHS exposure. This study examined whether contextual social deprivation - variously based on living in a house without a car, that was overcrowded, or had an unemployed member (s) - had an independent association with SHS exposure at both individual and regional levels among Chinese residents.
A cross-sectional multistage sampling design was utilized to interview subjects from 6 selected cities in China. A standardized questionnaire selected sociodemographic characteristics, contextual social deprivation and SHS exposure. Multilevel logistic regression models were used to assess the association between social deprivation and SHS exposure.
A total of 5782 valid questionnaires were collected in this study. Among 2930 non-smokers, the SHS exposure prevalence was 21.9% (95% CI: 19.5- 24.30). Multilevel logistic regression showed a negative association between household income, regional GDP, and SHS exposure, respectively, and positive associations between contextual social deprivation and SHS exposure.
Findings support the central proposition that contextual social deprivation must be factored into SHS exposure messages. Our research underscores the importance of reducing health inequality in controlling SHS exposure.
社会剥夺是健康及相关行为的一个已知决定因素。许多研究已将社会经济因素与二手烟暴露联系起来。然而，尚无研究考察社会剥夺与二手烟暴露之间的关系。本研究考察了基于居住在没有汽车的房屋、居住空间过度拥挤或有失业家庭成员等不同情况的背景性社会剥夺，在中国居民的个体和区域层面上与二手烟暴露是否存在独立关联。
采用横断面多阶段抽样设计，对来自中国6个选定城市的受试者进行访谈。一份标准化问卷选取了社会人口学特征、背景性社会剥夺和二手烟暴露情况。使用多水平逻辑回归模型评估社会剥夺与二手烟暴露之间的关联。
本研究共收集到5782份有效问卷。在2930名不吸烟者中，二手烟暴露患病率为21.9%（95%置信区间：19.5 - 24.30）。多水平逻辑回归显示，家庭收入、区域国内生产总值分别与二手烟暴露呈负相关，背景性社会剥夺与二手烟暴露呈正相关。
研究结果支持这样一个核心观点，即背景性社会剥夺必须纳入二手烟暴露信息中。我们的研究强调了在控制二手烟暴露方面减少健康不平等的重要性。
