This study investigated whether socioeconomic factors explain racial/ethnic differences in regular smoking initiation and cessation.
Data were derived from the CARDIA study, a cohort of 5115 healthy adults aged 18 to 30 years at baseline (1985-1986) and recruited from the populations of 4 US cities. Respondents were followed over 10 years.
Among 3950 respondents reexamined in 1995-1996, 20% of Whites and 33% of African Americans were smokers, as compared with 25% and 32%, respectively, in 1985-1986. On average, African Americans were of lower socioeconomic status. Ten-year regular smoking initiation rates for African American women, White women, African American men, and White men were 7.1%, 3.5%, 13.2%, and 5.1%, respectively, and the corresponding cessation rates were 25%, 35.1%, 19.2%, and 31.3%. After adjustment for socioeconomic factors, most 95% confidence intervals of the odds ratios for regular smoking initiation and cessation in African Americans vs Whites included 1.
Less beneficial 10-year changes in smoking were observed in African Americans, but socioeconomic factors explained most of the racial disparity.
本研究调查了社会经济因素是否能解释在经常吸烟的开始和戒烟方面的种族/民族差异。
数据来源于CARDIA研究，该队列在基线时（1985 - 1986年）有5115名18至30岁的健康成年人，从美国4个城市的人群中招募。对受访者进行了10年的随访。
在1995 - 1996年重新接受检查的3950名受访者中，20%的白人以及33%的非裔美国人是吸烟者，相比之下，在1985 - 1986年这两个比例分别为25%和32%。平均而言，非裔美国人的社会经济地位较低。非裔美国女性、白人女性、非裔美国男性和白人男性的十年经常吸烟起始率分别为7.1%、3.5%、13.2%和5.1%，相应的戒烟率分别为25%、35.1%、19.2%和31.3%。在对社会经济因素进行调整后，非裔美国人与白人在经常吸烟起始和戒烟方面的优势比的大多数95%置信区间都包含1。
非裔美国人在吸烟方面的十年变化不太有利，但社会经济因素解释了大部分种族差异。
