African American men experience increases in smoking during the young adult transition. Exposure to childhood adversity, a risk factor which disproportionately affects African American men, has been identified as a robust precursor to health risk behavior in general and cigarette smoking in particular. The intermediate mechanisms that transmit the influence of early adversity to smoking behavior are not well understood.
We tested a model of the escalation of smoking behaviors among young adult African American men, investigating sleep disturbance and delayed reward discounting as intermediate factors linking adverse childhood experiences with smoking.
Hypotheses were tested with three waves of data (M = 20.34, M = 21.92, M = 23.02) from 505 African American men living in rural counties in South Georgia. Men provided self-report data on their adverse childhood experiences, sleep problems, and smoking behavior using audio-assisted computer self-interviews. Men also completed a computer-based delayed reward discounting task.
Structural equation modeling analyses supported our hypotheses: Adverse childhood experiences predicted poor sleep adequacy, which forecast increases in delayed reward discounting; discounting, in turn, predicted increased smoking. Significant indirect pathways were detected linking adversity to discounting via sleep adequacy and linking sleep adequacy to smoking via discounting.
Prevention and intervention researchers can draw on these findings to develop programs that focus on sleep adequacy to reduce smoking in African American men exposed to childhood adversity.
非裔美国男性在青年到成年的过渡期间,吸烟率会上升。童年逆境是一个风险因素,它不成比例地影响着非裔美国男性,已经被确定为一般健康风险行为,尤其是吸烟行为的一个强有力的前因。将早期逆境的影响传递到吸烟行为的中间机制尚不清楚。
我们测试了一个年轻的非裔美国男性吸烟行为升级的模型,研究睡眠障碍和延迟奖励折扣作为将不良童年经历与吸烟联系起来的中间因素。
使用来自佐治亚州南部农村县的 505 名非裔美国男性的三波数据(M = 20.34、M = 21.92、M = 23.02)来检验假设。男性使用音频辅助计算机自我访谈,提供关于他们童年逆境、睡眠问题和吸烟行为的自我报告数据。男性还完成了基于计算机的延迟奖励折扣任务。
结构方程模型分析支持了我们的假设:童年逆境预测睡眠充足度不佳,这预示着延迟奖励折扣的增加;折扣反过来又预示着吸烟量的增加。通过睡眠充足度,逆境与折扣之间存在显著的间接途径;通过折扣,睡眠充足度与吸烟之间也存在显著的间接途径。
预防和干预研究人员可以借鉴这些发现,制定关注睡眠充足度的计划,以减少暴露于童年逆境的非裔美国男性的吸烟行为。
