Assessment of nicotine dependence among smokers in a selected rural population in Kerala, India.

OBJECTIVES: An attempt was made to understand the nicotine dependence of smokers selected for an ongoing smoking cessation intervention programme in rural Kerala, India. METHODS: Data were collected from resident males in the age group of 18 to 60 years from 4 randomly allocated community development blocks of rural Thiruvananthapuram district (2 intervention and 2 control groups). Trained accredited social health activist workers were utilised to collect data from all groups through face to face interview. Nicotine dependence among participants was assessed by means of the six-item Fagerstrom Test for Nicotine Dependence (FTND) translated into the local language. The internal consistency of FTND was computed using Cronbach's alpha coefficient. Criterion validity (concurrent) was assessed by correlations of nicotine dependence scores with age at initiation of smoking and cumulative smoking volume in pack-years. RESULTS: Among the 928 smokers identified, 474 subjects were in the intervention area (mean age =44.6 years, SD =9.66 years) and 454 in the control area (mean age= 44.5 years, SD =10.30 years). The overall FTND score among current daily smokers was 5.04 (SD: 5.05). FTND scores in the control and intervention areas were 4.75 (SD: 2.57) and 4.92 (SD: 2.51) respectively. The FTND scores increased with age and decreased with higher literacy and socioeconomic status. The average FTND score was high among smokers using both bidi and cigarettes (mean 6.10, SD 2.17). Internal consistency analysis yielded a Cronbach's alpha coefficient of 0.70 in a subsample of 150 subjects, a moderate result. The association of the scale was strongest, with the number of pack-years smoked (rho = 0.677, p < 0.001). CONCLUSION: A moderate level of nicotine dependence was observed among smokers in the current study. Tobacco cessation strategies could be made more cost effective and productive if a baseline assessment of nicotine dependence is completed before any intervention.

Self-reported tobacco use, knowledge on tobacco legislation and tobacco hazards among adolescents in rural Kerala State.

CONTEXT: Tobacco consumption initiated during the adolescent period is a major contributor to the pathogenesis of fatal diseases in adulthood. Information on tobacco use and awareness regarding tobacco legislation and hazards among adolescents in rural Kerala is limited. AIMS: To assess the prevalence of tobacco use among adolescent students in a rural district in Kerala state and to understand the extent of awareness about the prominent legislative measures against tobacco and tobacco hazards. MATERIALS AND METHODS: Data on awareness regarding health hazards due to tobacco use and legislation against tobacco consumption were collected from students of 15 randomly selected high schools in an educational sub-district in Kerala, using a cross-sectional study design. Chi-square and Fisher's exact test statistics were used for statistical analysis. RESULTS: A total of 1473 students participated in the study, of which 79% were males (mean age 15.4 years, SD 1.5). The overall prevalence of 'current tobacco users' was 8%. A significant association between age and tobacco use was noted among tobacco habitués (P<0.05). Awareness regarding legislation against smoking in public places was more in the higher age-groups (P<0.05). Females were more aware of the 'smoking ban' than males (P<0.05). Our survey of the awareness regarding the hazards associated with tobacco use revealed that 41.5% of the students knew about the link between oral cancer and tobacco, with the awareness being greater among females than among males (64.3% vs 35.4%). CONCLUSION: The finding that tobacco consumption increases with age is a matter of concern. In addition to their clinical work, dental professionals should also educate the public on the hazards of tobacco and conduct tobacco cessation programmes for adolescent groups to control the tobacco epidemic.
