The majority of smoking cessation research has focused on heavy smokers. African Americans (AA) are less likely than the general population to be heavy smokers. Thus, little is known about the smoking and psychosocial characteristics of lighter AA smokers. The present study compared the baseline demographic, smoking, and psychosocial characteristics of light (5-10 cigarettes per day; n=86) and moderate to heavy (>10 cigarettes per day; n=286) AA smokers enrolled in a smoking cessation clinical trial. Results indicated no differences between groups on demographic variables. However, light smokers (LS) were less dependent on smoking, reported more previous quit attempts, and had higher self-efficacy to quit than moderate to heavy smokers (MHS). On a measure of withdrawal, LS reported less pre-quit craving and less difficulty concentrating than MHS. In addition, LS reported lower perceived stress, fewer symptoms of depression, and greater positive affect than AA MHS. These findings highlight important similarities and differences between AA LS and MHS, and have implications for the treatment of AA smokers.
大多数戒烟研究都集中在重度吸烟者身上。非裔美国人(AA)成为重度吸烟者的可能性低于普通人群。因此,对于轻度吸烟的非裔美国人的吸烟及心理社会特征知之甚少。本研究比较了参加戒烟临床试验的轻度(每天吸5 - 10支烟;n = 86)和中度至重度(每天吸超过10支烟;n = 286)非裔美国吸烟者的基线人口统计学、吸烟及心理社会特征。结果表明,两组在人口统计学变量上没有差异。然而,轻度吸烟者(LS)对吸烟的依赖程度较低,报告的既往戒烟尝试次数更多,并且戒烟的自我效能感高于中度至重度吸烟者(MHS)。在一项戒断指标上,轻度吸烟者报告的戒烟前渴望程度较低,注意力集中困难程度也低于中度至重度吸烟者。此外,与非裔美国中度至重度吸烟者相比,轻度吸烟者报告的感知压力更低,抑郁症状更少,积极情绪更高。这些发现凸显了非裔美国轻度吸烟者和中度至重度吸烟者之间重要的异同点,对非裔美国吸烟者的治疗具有启示意义。
