A longitudinal analysis of non-daily smokers: the Hispanic Community Health Study/Study of Latinos (HCHS/SOL)

Abstract Purpose Non-daily smoking is increasing in the United States and common among Hispanic/Latino smokers. We characterized factors related to longitudinal smoking transitions in Hispanic/Latino non-daily smokers. Methods The Hispanic Community Health Study/Study of Latinos is a population-based cohort study of Hispanics/Latinos ages 18-74. Multinomial logistic regression assessed baseline factors (2008-2011) associated with follow-up smoking status (2014-2017) in non-daily smokers (n=573), accounting for complex survey design. Results After ∼six years, 22% of non-daily smokers became daily smokers, and 37% remained non-daily smokers. Factors related to follow-up smoking status were number of days smoked in the previous month, household smokers, education, income and insurance. Those smoking ≥16 of the last 30 days had increased risk of becoming a daily smoker [vs high school versus Conclusions Many Hispanic/Latino non-daily smokers became daily smokers, which may increase their risk of adverse health outcomes. Addressing different smoking patterns in primary care may be useful to prevent smoking-related diseases.
