CAMPO-ARIAS, Adalberto. The prevalence of nicotine-dependency in some populations: a systematic review. Rev. salud pública [online]. 2006, vol.8, n.1, pp. 98-107. ISSN 0124-0064.
Tobacco use is the leading cause of preventable morbidity-mortality around the world. Nicotine dependence (ND) explains why people continue to smoke even though the harmful outcome associated with tobacco use is well-known. The object of this review was to establish current and one-year prevalence of ND among adults from the general population. Ebsco, Embase, Lilacs, Ovid, Proquest, and PubMed were systematically reviewed. The key words used were: smoking, tobacco, cigarette, nicotine, dependence, adults, general population and cross-sectional study. Only research carried out in English, Portuguese and Spanish was reviewed. A descriptive analysis of six articles was made. Current ND prevalence ranged from 27,8 % to 55 % (44,7 % weighted average) and annual prevalence from 26 % to 46,9 % (37,7 % weighted average). ND was independent of gender and higher amongst heavy smokers. It was concluded that ND prevalence is close to 45 % amongst current regular smokers and affected 38 % of smokers during the last year. More research is needed.
