Cigarette smoking is on the rise among adolescents in the United States. Although both African-American and white adolescents have experienced increases in cigarette smoking over time, the prevalence of smoking has remained consistently lower among African-American adolescents than their white counterparts. The purpose of this study was to determine whether the race differential in the prevalence of cigarette smoking is attributed to differences in selected lifestyle behaviors and demographic factors.
A cross-sectional study was conducted among African-American and white adolescents (aged 12 to 17 years) who participated in the Youth Risk Behavior Survey supplement to the 1992 National Health Interview Survey. Analyses were restricted to those who had complete data on all study variables (n = 5569). Logistic regression analysis was used to estimate the prevalence odds ratios (POR) of current smoking for white adolescents (versus African-American adolescents) before and after adjustment for confounding factors.
The crude POR of current smoking for white adolescents compared with African-American adolescents was 2.8 (95% confidence interval = 2.1 to 3.9). Simultaneous adjustment for confounding factors resulted in a POR of 2.6 (95% confidence interval = 1.8 to 3.7).
Selected lifestyle behaviors and demographic factors do not account for the race differential in the prevalence of adolescent cigarette smoking. This study underscores the need for more research on contributors to the race gap. Such research could advance theoretical understanding of the etiology of cigarette smoking among adolescents and lead to more effective smoking prevention programs for all youths.
在美国,青少年吸烟率呈上升趋势。尽管随着时间推移,非裔美国青少年和白人青少年的吸烟率均有所上升,但非裔美国青少年的吸烟率一直低于白人青少年。本研究的目的是确定青少年吸烟率的种族差异是否归因于特定生活方式行为和人口统计学因素的差异。
对参与1992年全国健康访谈调查青少年危险行为调查补充调查的非裔美国青少年和白人青少年(年龄在12至17岁之间)进行了一项横断面研究。分析仅限于那些在所有研究变量上都有完整数据的青少年(n = 5569)。采用逻辑回归分析来估计在调整混杂因素前后白人青少年(与非裔美国青少年相比)当前吸烟的患病率比值比(POR)。
与非裔美国青少年相比,白人青少年当前吸烟的粗POR为2.8(95%置信区间 = 2.1至3.9)。对混杂因素进行同时调整后,POR为2.6(95%置信区间 = 1.8至3.7)。
特定生活方式行为和人口统计学因素并不能解释青少年吸烟率的种族差异。本研究强调需要对种族差距的影响因素进行更多研究。此类研究可以推进对青少年吸烟病因的理论理解,并为所有青少年带来更有效的吸烟预防项目。
