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.
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 39 218.
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.
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.
（1）考察家庭社会经济地位（SES）与家庭是否花钱购买香烟之间的关系；（2）考察吸烟家庭中用于购买香烟的家庭总支出比例的社会经济差异。
我们汇总了 2010-2015 年连续六年的消费者支出访谈调查数据。访谈采用了一份有关家庭收入、人口统计学和支出（包括香烟支出）的结构化问卷。报告在前 3 个月有香烟支出的家庭被界定为吸烟家庭。SES 指标包括家庭贫困状况、家庭户主的教育程度和职业。采用逻辑回归评估家庭吸烟状况与 SES 的关系。采用分数逻辑回归评估香烟支出占家庭总支出的比例与 SES 的关系。分析样本量为 39218 户。
SES 较低的家庭更有可能花钱购买香烟。与高于贫困线 300%的家庭相比，贫困家庭的这一概率为 1.86（95%CI1.61 至 2.16）；与至少拥有学士学位的家庭户主相比，拥有高中以下学历的家庭户主的这一概率为 3.37（95%CI2.92 至 3.89）；与蓝领工作的家庭户主相比，从事管理职业的家庭户主的这一概率为 1.45（95%CI1.26 至 1.66）。同样，SES 较低的吸烟家庭用于购买香烟的家庭总支出比例也较高。
SES 较低的家庭更有可能花钱购买香烟，并且用于购买香烟的家庭总支出比例也较高。我们建议采取有效措施，减少 SES 较低的吸烟者吸烟。
