To examine the racial difference and trends in cigarette smoking among adolescents from 1999 to 2018.
We analyzed the data of 10,760 adolescents aged 12-19 who participated in the National Health and Nutrition Examination Surveys (NHANES), 1999-2018. Current tobacco smoking (CTS) was defined as participants with serum cotinine ≥10 ng/mL. Adjusted biennial prevalence ratios (abiPR: the ratio associated with a two-year increase in time) were estimated.
Diverging trends in CTS prevalence were revealed in adolescents. The steepest decrease occurred in Hispanics aged 12-17, with 15% declining every two calendar years [abiPR = 0.85(0.77, 0.94)]. The sharpest increase occurred with Blacks aged 18-19 years [abiPR = 1.06(0.99, 1.14)]. A crossover of prevalence trend between Blacks and Whites occurred in adolescents aged 18-19 years old due to the diverging trends. The average CTS prevalence was significantly higher in Whites than in Blacks in the early [(1999-2008, 13.65% (11.85%, 15.46%) vs. 8.80% (7.55%, 10.04%)], but Blacks had a higher average in recent years [(2009-2018, 8.32% (6.53%, 10.12%) vs. 7.77% (5.86%, 9.68%)]. For adolescents aged 18-19 years, the survey cycles or calendar years linearly explained 71% of the variations in the prevalence for Hispanics, 60% for Whites, but only 1% for Blacks.
A crossover in the trend of current tobacco smoking occurred between 1999 and 2018 due to an increase in prevalence among Black adolescents and a significant decrease in prevalence among other racial groups.
研究 1999 年至 2018 年期间青少年的吸烟率的种族差异和趋势。
我们分析了 1999 年至 2018 年期间参加国家健康和营养检查调查（NHANES）的 10760 名 12-19 岁青少年的数据。当前吸烟（CTS）定义为血清可替宁≥10ng/ml 的参与者。估计了调整后的每两年流行率比（abiPR：与时间增加两年相关的比值）。
在青少年中，CTS 流行率呈现出不同的趋势。下降幅度最大的是 12-17 岁的西班牙裔，每两年下降 15%[abiPR=0.85（0.77，0.94）]。上升幅度最大的是 18-19 岁的黑人[abiPR=1.06（0.99，1.14）]。由于趋势的不同，黑人与白人青少年之间的流行率趋势出现了交叉。白人青少年的平均 CTS 患病率明显高于黑人，在早期[（1999-2008 年，13.65%（11.85%，15.46%）比 8.80%（7.55%，10.04%）]，但近年来黑人的平均患病率更高[（2009-2018 年，8.32%（6.53%，10.12%）比 7.77%（5.86%，9.68%）]。对于 18-19 岁的青少年，调查周期或日历年线性解释了西班牙裔流行率变化的 71%，白人的 60%，而黑人仅为 1%。
由于黑人青少年吸烟率的上升和其他种族群体吸烟率的显著下降，1999 年至 2018 年期间，当前吸烟的趋势发生了交叉。
