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 used to characterize diverse populations of cigarette smokers and to determine the effectiveness of individualized smoking cessation intervention programs. AIM: This study aimed to investigate the correlates of nicotine dependence among currently established cigarette smokers in Nigeria. SETTING: 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: Nicotine dependence (ND) was measured 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 the factors associated with severe nicotine dependence. RESULTS: The analytical sample was drawn from 487 adults. Within our sample, 69%, 27%, and 3.9% had low, moderate, and severe ND levels, respectively (p = 0.02), whereas among daily cigarette smokers, 48.1%, 44.3%, and 7.6% had low, moderate, and severe ND levels, respectively (p <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, male sex, and those with reduced harm perceptions regarding 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.
