Factors Associated with Tobacco Use in Students Attending Local Government Schools in Mumbai, India

Using the Theory of Planned Behavior to Explain and Predict Areca Nut Use Among Adolescents in India: An Exploratory Study

Context

Areca nut, used alone or in combination with tobacco, contributes to the high oral cancer burden in India. Used widely by adolescents, who perceive it as a harmless substance, areca nut is addictive and considered a precursor to tobacco use. Given its serious implications for addictiveness and physical health, urgent preventive interventions for areca nut use are required in India and South-East Asia. Studies examining the role of health behavior theory in explaining and predicting areca nut use and for development of its prevention among adolescents are scarce.

Aim

This study explored the role of the components of Theory of Planned Behavior (TPB) such as attitudes, subjective norms, perceived behavioral control, and intention in predicting areca nut use among adolescents.

Settings and Design

Observational study with cross-sectional design conducted with 1884 male and female adolescents attending low-income schools in Mumbai, India.

Methods and Material

Self-administered surveys were used to gather data on age, gender, behavioral factors and areca nut use.

Statistical Analysis Used

Chi-square and Mann Whitney test for bivariate and logistic regression for multivariate analysis.

Results

Around 27.2% of 1884 participants were areca nut users. The mean age of users was 13.75 years. Intention-to-use and perceived behavioral control were statistically significant predictors of actual areca nut use (p<0.001). The components of TPB such as attitude, perceived subjective social norms, and perceived behavioral control had a statistically significant effect on the intention-to-use areca nut (p<0.05).

Conclusion

This exploratory study indicates that constructs from TPB could help us understand and predict areca nut use. However, more rigorous future research is required to generate insights that help craft effective theory-based behavioral interventions for areca nut prevention and cessation in adolescents.

Prevalence and Social Contextual Factors of Smokeless Tobacco Use: Insights from Schools of Delhi, India

Background:

It was observed that adult users start tobacco use in childhood or adolescence. The influence of digital and print media, social acceptance among peers, and in order to mimic role models from films attracts youth towards tobacco. Hence this study was conducted to assess the prevalence of smokeless tobacco (SLT) use among school-going adolescents with the assessment of the influencing factors such as exposure at school, home, and public places along with the role of various media in SLT use by adolescents.

Methods:

Cross sectional study was conducted with 860 students of class 9^th -12^th enrolled in schools. Purposive sampling of three schools was done from the study area to reach desired sample size. All the students of class 9^th - 12^th within selected schools were given chance to participate in the study. Data collection was done using pretested modified Global Youth Tobacco Survey (GYTS) questionnaire.

Results:

Consumption of smokeless tobacco (SLT) was observed in 79 (11%) of 714 subjects. Significantly higher proportion (18.4%) of study subjects consumed SLT who were exposed to tobacco at school premises and 19.1% of study subjects who were exposed to teacher using SLT in schools compared to non-exposed group. (p=0.016). It was observed that 8.1% of subjects without any exposure to tobacco at home and 9.8% of subjects without exposure to tobacco at outdoor public space consumed SLT. Consumption of SLT use was highest (16.7%) among subjects exposed to tobacco advertisement or promotion through social media (p=0.04).

Conclusion:

High prevalence of SLT was detected among adolescents in school. Factors such as exposure to tobacco at home, public places, school and school teacher using SLT, exposure of tobacco advertisement and promotion via different modes of media was found to be significantly associated with the use of SLT in the adolescents of school.

LifeFirst: Impact of a school-based tobacco and supari cessation intervention among adolescent students in Mumbai, India

INTRODUCTION

The youth are a vulnerable population-group for tobacco-related harms. Schools are an excellent setting for health promotion; yet there is a dearth of school-based cessation interventions, rarely evaluated for their impact. Here, we assess the impact of the LifeFirst program: an ongoing tobacco and supari (areca nut) cessation intervention delivered to students from corporation schools in Mumbai city.

METHODS

We used a prospective quasi-experimental design with an intervention and a control arm embedded within an ongoing LifeFirst program in select schools. We used a difference-in-difference analysis with baseline and end-line surveys to assess the program's impact on students' knowledge about harms, students' refusal skills, and prevalence of tobacco/supari use. We report our work using the TREND statement checklist.

RESULTS

A total of 959 students registered in the LifeFirst program. In our analysis, we included 827 students who completed both the baseline and end-line surveys. Postintervention, we found both tobacco and supari use reduced substantially among the intervention group while tobacco use increased among the control group. The difference-in-difference estimates show a statistically significant reduction of 17.9 and 38.1 percentage points in the intervention group for tobacco and supari use respectively, beyond the reduction in the control group.

CONCLUSIONS

The LifeFirst program was successful in reducing tobacco and supari use among the study participants and protected students in the intervention group against new uptake of tobacco. It helped improve knowledge score and refusal skills among students. Implementation and evaluation of similar school-based programs should be considered as part of a multi-strategy approach to reducing tobacco use among young people.

Socio-demographic and socioeconomic differences in tobacco use prevalence among Indian youth

The study aims to assess the association between socio-demographic factors such as age, gender, area of residence, father's education, and standard of living and the likelihood of tobacco use in adolescence. We conducted secondary data analysis on a large scale cross-sectional study comprising of 1386 adolescents, living in regions representative of three different socioeconomic positions in New Delhi. Data was collected through clinical oral examination and interviewer-administered questionnaire. Multiple logistic regression analysis with an unadjusted model for assessing the association between the respective explanatory variable and ever tobacco use. Sequential models were adjusted for confounders as well as the other explanatory variables. The number of tobacco users was 185 (13%). Gender wise tobacco use shows significant (P = 0.001) difference between girls vs. boys; the girls are about 40% less likely to use tobacco than boys (OR = 0.58, 95% CI = 0.42-0.80). Among socio-economic classes, residents of resettlement colonies were twice as likely to use tobacco as middle/upper middle class residents (OR = 2.26, 95% CI = 1.45-3.53). Adolescents with fathers educated up to the primary or secondary levels were almost twice likely to have used tobacco than those with fathers educated till graduation or above (OR = 2.08 95% CI = 1.30-3.34 vs. OR = 2.24, 95% CI = 1.43-3.51, respectively). Significant (P = 0.001) difference in tobacco use among adolescents was also observed based on their standard of living. A significant association exists in terms of area of residence, father's education, and standard of living.
