African American smokers suffer disproportionately from tobacco-related disease caused, in part, by lower rates of smoking cessation. We examined whether smoke-free home policies and delay discounting were differentially associated with cigarettes smoked per day (CPD) and nicotine dependence (ND) among African Americans and Whites.
Secondary data analysis was conducted using data from 65 African American (n = 40) and White (n = 25) smokers who completed measures of CPD, ND, tobacco craving, stress, depression, home smoking policy, and delay discounting.
A significant interaction was found between race and home smoking policy on CPD (B = -11.21, p = 0.002) and ND (B = -3.42, p = 0.004). Smoke-free policies in the home were associated with fewer CPD and lower ND levels among Whites, but not among African Americans. Whites who allowed smoking in their homes had significantly greater mean CPD and higher mean ND than their counterparts who did not allow smoking in the home. Among African American smokers, there were no differences in CPD and ND among those who allowed smoking in their home versus those who did not.
The findings extend the scientific literature by suggesting that a malleable environmental factor (home smoking policy) commonly associated with cessation among Whites does not have the same influence on cessation among African American.
非裔美国烟民因烟草相关疾病而遭受不成比例的痛苦,部分原因是戒烟率较低。我们研究了无烟家庭政策和延迟折扣是否与非裔美国人和白人的每日吸烟量(CPD)和尼古丁依赖(ND)存在差异关联。
使用来自 65 名非裔美国(n=40)和白人(n=25)吸烟者的二次数据分析数据,这些吸烟者完成了 CPD、ND、吸烟渴求、压力、抑郁、家庭吸烟政策和延迟折扣的测量。
发现种族和家庭吸烟政策对 CPD(B=-11.21,p=0.002)和 ND(B=-3.42,p=0.004)存在显著交互作用。家庭中实行无烟政策与白人的 CPD 和 ND 水平降低相关,但与非裔美国人无关。家中允许吸烟的白人比家中不允许吸烟的白人有更高的 CPD 和更高的 ND 均值。在非裔美国烟民中,家中允许吸烟与不允许吸烟的人在 CPD 和 ND 方面没有差异。
这些发现通过表明与白人戒烟相关的一个可改变的环境因素(家庭吸烟政策)对非裔美国人的戒烟没有相同的影响,从而扩展了科学文献。
