目的探讨（1）家庭社会经济地位（SES）与家庭是否在香烟上花钱的关系，（2）吸烟家庭在香烟上花费的家庭总支出比例的社会经济差异。方法汇总2010-2015年连续6年的消费者支出访谈调查数据。访谈涉及一份关于家庭收入、人口统计和支出（包括香烟支出）的结构化问卷。在过去3个月内申报香烟开支的住户被视为吸烟住户。社会经济地位指标是家庭贫困状况、教育和户主职业。Logistic回归分析被用来评估家庭吸烟状况与SES的关联。分数逻辑回归被用来评估香烟支出占家庭总支出的比例与社会经济地位的关联。分析样本量为39218人。结果低社经水平家庭购买香烟的可能性较高。贫困家庭与贫困线300%以上家庭相比，（95% CI 1.61 - 2.16），由高中以下学历的人担任户主的家庭与由至少有学士学位的人担任户主的家庭相比，（95%CI 2.92至3.89），蓝领工人为户主的家庭比管理人员为户主的家庭在香烟上花钱的几率高1.45（95%CI 1.26至1.66）。同样，家庭总支出的比例在较低的SES吸烟households.Conclusion家庭更有可能把钱花在香烟上，花在香烟上的总支出的比例更大。我们建议在低SES吸烟者中有效减少吸烟的策略。
Objectives To examine (1) the association between household socioeconomic status (SES) and whether a household spends money on cigarettes and (2) socioeconomic variations in proportion of total household expenditure spent on cigarettes among smoking households.Methods We pooled data from six consecutive years, 2010-2015, of the Consumer Expenditure Interview Survey. The interviews involved a structured questionnaire about household income, demographics and expenditures including expenditure on cigarettes. Households that reported cigarette expenditure in the previous 3 months were distinguished as smoking households. SES indicators were household poverty status, education and occupation of the head of household. Logistic regression was used to assess the association of household smoking status with SES. Fractional logistic regression was used to assess the association of cigarette expenditure as a proportion of total household expenditure with SES. The analysis sample size was 39218.Results The probability of spending money on cigarettes was higher among lower SES households. Households in poverty compared with those above 300% of poverty threshold had 1.86 (95% CI 1.61 to 2.16), households headed by a person with less than high school education compared with those headed by a person with at least a bachelor's degree had 3.37 (95% CI 2.92 to 3.89) and households headed by a blue-collar work compared with those headed by a person in a managerial occupation had 1.45 (95% CI 1.26 to 1.66) higher odds of spending money on cigarettes. Similarly, the proportion of total household expenditure spent on cigarettes was higher among lower SES smoking households.Conclusion Lower SES households are more likely to spend money on cigarettes and spend a larger proportion of their total expenditure on cigarettes. We recommend strategies effective in reducing smoking among low SES smokers.
