Age Differences in the Trends of Smoking Among California Adults: Results from the California Health Interview Survey 2001-2012.
The aim is to study the trends of cigarette smoking from 2001 to 2012 using a California representative sample in the US. Data was taken from the California Health Interview Survey (CHIS) from 2001 to 2012, which is a population-based, biennial, random digit-dial telephone survey of the non-institutionalized population. The CHIS is the largest telephone survey in California and the largest state health survey in the US. 282,931 adults (n = 184,454 with age 18-60 and n = 98,477 with age >60) were included in the analysis. Data were weighted to be representative and adjusted for potential covariance and non-response biases. During 2001-2012, the prevalence of current smoking decreased from 18.86 to 15.4 % among adults age 18-60 (β = -0.8, p = 0.0041). As for adults age >60, the prevalence of current smoking trend decreased with variations, started from 9.66 % in 2001, slightly increased to 9.74 % in 2003, but then gradually decreased, falling to 8.18 % in 2012. In 2012, there was a 14 % reduction of daily smoking adults age 18-60 (OR 0.84, 95 % CI 0.76-0.93, p = 0.0006) compared to 2001, while no significant reduction of daily smoking was observed for those age >60. The reductions of smoking prevalence for adults younger than 60 are encouraging. However, there is a concern for smoking cessation rates among those older than 60 years of age, particularly for African Americans.
