Correlates of Nicotine Dependence Among Current Cigarette Smokers in Nigeria

BACKGROUND: _ The level of dependence on nicotine, the main addictive chemical in tobacco, is a substance-related disorder that can be utilized to characterize diverse populations of cigarette smokers and also to determine the effectiveness of individualized smoking cessation intervention programs. AIM: This study investigates the correlates of nicotine dependence among current established cigarette smokers in Nigeria. SETTINGS: _ We conducted a cross-sectional survey among a cohort of current established cigarette smokers (100+ sticks in a lifetime and someday/everyday cigarette smokers) in Lagos, Nigeria. METHODS: The dependent measure was nicotine dependence (ND) using the Fagerstrom scale; independent measures were demographics, harm perception, binge alcohol drinking, and past-year internalizing and externalizing problems. Logistic regression models were used to investigate factors associated with severe nicotine dependence. RESULTS: The analytic sample was drawn from 487 adults. Within our sample, 69%, 27%, and 3. 9% had low, moderate, and severe ND levels, respectively (ₚ-value_: 0. 02) ; while among daily cigarette smokers, 48. 1%, 44. 3%, and 7. 6% had low, moderate and severe ND levels, respectively (ₚ-value_: <0. 001). In the regression analysis, older age (aOR: 1. 03; 95% CI: 1. 01, 1. 06) and being male (vs, female) (aOR: 3. 70; 95% CI: 1. 58, 8. 15), and reduced cigarette harm perceptions (aOR: 2. 85; 95% CI: 1. 75, 4. 66) were associated with increased odds of moderate/severe ND. CONCLUSION: Older age, males, and those with reduced harm perceptions about cigarette use had increased odds of moderate/severe ND. Our preliminary findings provide baseline results characterizing use behaviors among relatively understudied current established cigarette smokers in Nigeria.
