Because household smoking levels and adoption of domestic smoking rules may be endogenously related, we estimated a nonrecursive regression model to determine the simultaneous relationship between home smoking restrictions and household smoking.
We used data from a May-June 2012 survey of Philadelphia, Pennsylvania, households with smokers (n = 456) to determine the simultaneous association between smoking levels in the home and the presence of home restrictions on smoking.
We found that home smoking rules predicted smoking in the home but smoking in the home had no effect on home smoking restrictions.
Absent in-home randomized experiments, a quasi-experimental causal inference suggesting that home smoking rules result in lower home smoking levels may be plausible.
由于家庭吸烟水平和家庭吸烟规则的采用可能存在内生关系，我们估计了一个非递归回归模型，以确定家庭吸烟限制与家庭吸烟之间的同时关系。
我们使用了 2012 年 5 月至 6 月对宾夕法尼亚州费城家庭（吸烟者 n=456）进行的调查数据，以确定家庭吸烟水平与家庭吸烟限制同时存在的关联。
我们发现家庭吸烟规则预测了家庭中的吸烟情况，但家庭中的吸烟情况对家庭吸烟限制没有影响。
在没有家庭内随机实验的情况下，一种准实验性因果推理表明，家庭吸烟规则会导致家庭吸烟水平降低，这可能是合理的。
