Changes in Smoking Behavior among US Young Workers from 2005 to 2010: The Role of Occupation

Background:

Little is known on recent changes in smoking behavior among young workers (18 - 24 years) by occupation. This study aims to examine these changes between 2005 and 2010.

Methods:

Using data from 2005 and 2010 National Health Interview Survey Tobacco Supplement, (n=55,142), we examined changes in smoking behavior in young workers by occupation (white-collar, blue-collar, and services). Logistic regression analysis was performed to identify predictors of smoking among them.

Results:

The prevalence of current smoking declined significantly in white-collar workers (23.5% to 15.4%; P = 0.0009). Age of initiation increased (15.7+ 0.18 to 16.7+0.30; P=0.006), and number of cigarettes smoked per day decreased (18.0+2.5 to 12.3 +1.0; P=0.04) significantly in blue-collar workers. In the regression analysis, workers were more likely to smoke in 2005 than 2010 (OR=1.48, 95% CI 1.20-1.83). Males were more likely to smoke than females (1.18, 1.11-1.25). Hispanics were less likely to smoke than non-Hispanic whites (0.32, 0.23-0.45). Those with >12 years education were less likely to smoke relative to <12 years (0.32, 0.22-0.47). Blue-collar workers and those without health insurance (1.45, 1.08-1.96; 1.49, 1.18-1.89, respectively) were more likely to smoke.

Conclusion:

Smoking prevalence was stable in service workers, and declined non-significantly in blue-collar workers. The significant decline in white-collar smoking suggests that this group has benefited the most from tobacco control efforts. To reduce tobacco use disparities, additional resources should be used to target blue-collar and service workers as well as those with low education, and those lacking health insurance.
