Abstract
OBJECTIVES To describe the epidemiological status of oral cancer (OC) in India along with updates on risk factors, advances and gaps in preventive measures, treatment, costs of care and monitoring. METHODS Two national estimates of incidence and mortality were cited, one for 2016 by the Global Burden of Disease India Study and one based on projections for 2020 by GLOBOCAN. The National Cancer Registry Project provided local and regional incidence and trends using data from 2012-2016. Scientific literature, reports of the NCRP, the IARC and government press releases were also consulted. RESULTS Tobacco and areca nut habits are the major risk factors for OC in India. In the 1980s, intervention studies on oral screening, awareness generation and habit cessation in rural areas reduced tobacco use and oral leukoplakia. Lately, adoption of the tobacco control law and mass media communications have resulted in decreased tobacco use. However, the increasing popularity of highly carcinogenic tobacco products containing areca nut, with evasion of their bans, is increasing OC incidence. CONCLUSION Despite advances in care, there is growing incidence of OC, persisting poor awareness about the need to quit tobacco/areca nut/alcohol use and go for screening. Major efforts are needed to implement preventive activities.

CHILDREN (BASEL, SWITZERLAND) 2024; 11:387. [PMID: 38671604 PMCID: PMC11049245 DOI: 10.3390/children11040387] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Revised: 03/16/2024] [Accepted: 03/20/2024] [Indexed: 04/28/2024]
Abstract
In this follow-up study, we aimed to assess the effectiveness of the "I do not smoke, I exercise" anti-smoking preventive health education program. The program was based on the theory of planned behavior supplemented with life skills teaching and targeted at high school students. The intervention comprised ten one-hour online sessions, administered by physical education instructors. The study cohort comprised 222 students (109 boys, 113 girls) from 11 secondary schools, with an average age of 16.42 ± 1.36 years. Data collection involved pre- and post-intervention self-assessment questionnaires. The examined variables included attitudes towards smoking, intention to smoke, subjective norm, perceived behavioral control (PBC), knowledge about smoking, smoking behavior, exercise behavior, attitudes toward the program's implementation, and satisfaction with the program. A separate paired samples t-test revealed a significant improvement in students' knowledge about smoking (t217 = -5.605, p < 0.001, d = 0.38) and perceived behavioral control (t220 = -2.166, p < 0.05, d = 0.15) following the intervention. However, no significant changes were observed in the remaining variables. In addition, students' overall satisfaction with the implementation of the present health education program was high (M = 5.72 ± 1.39). These findings suggest that the health education smoking prevention intervention incorporates techniques and strategies that influence the perceived behavioral control variable, emphasizing students' strong interest in educationally theorized programs integrating technology into their design. Future studies should consider further examination of tobacco control strategies within the high school context.

Abstract
PURPOSE AND OBJECTIVES A process evaluation, the Uttarakhand Tobacco Free Initiative (UTFI), was conducted in 49 public high schools and colleges in the state of Uttarakhand, India, to measure program implementation, provide feedback to school administrators, and identify barriers to tobacco control. INTERVENTION APPROACH UTFI aims to 1) raise awareness and provide education and tools for teachers and school administrators about the dangers of tobacco use and secondhand smoke, 2) encourage participation in student-led activities to promote tobacco-free initiatives, and 3) enforce tobacco-free school policies in the state of Uttarakhand. EVALUATION METHODS We used the CDC evaluation framework to document key components and lessons learned from the UTFI. We distributed questionnaires to 71 teachers and principals in December 2016, to assess awareness of school activities and policies related to the initiative. Descriptive statistics were computed for quantitative data, and a thematic content analysis was used for qualitative data. RESULTS Of the 71 participants, 66 (92.9%) were aware of tobacco use policies in schools, and 63 (88.7%) agreed policies were enforced. Sixty-six participants (93.0%) said that they taught tobacco prevention-related topics, and 41 of 70 respondents (58.6%) reported that a student-led group helped to enforce tobacco-free policies in their schools. Of 69 respondents, almost all (n = 66) reported satisfaction with UTFI implementation. Challenges identified were related to tobacco products being readily accessible near school premises, lack of tobacco prevention materials, and tobacco use by school staff. IMPLICATIONS FOR PUBLIC HEALTH Successes of UTFI were documented by measuring different components of the process, including implementation of program activities and teacher and principal satisfaction. Results might help enhance key processes for the initiative and highlight some barriers to implementation, such as enforcing tobacco control policy off school premises. Continued efforts are needed to prevent tobacco use among young people.

Does adding a psychosocial cessation intervention to an existing life-skills and tobacco-prevention program influence the use of tobacco and supari among secondary school students?: Findings from a quasi-experimental trial in Mumbai, India. Tob Prev Cessat 2019; 5:45. [PMID: 32411907 PMCID: PMC7205047 DOI: 10.18332/tpc/113355] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2019] [Revised: 10/09/2019] [Accepted: 10/24/2019] [Indexed: 11/07/2022]
Abstract
INTRODUCTION This study aimed to test whether school-going adolescents who self-report tobacco and/or supari use are more likely to quit if a school-based psychosocial cessation intervention is added to an existing life-skills and tobacco-prevention program. METHODS A quasi-experimental trial with pre-test and post-test 20 weeks after the intervention was conducted with students from low-income families in 12 schools in Mumbai; six schools were randomly assigned to the intervention and the remaining to the comparison condition. Participants were students from grades 7, 8 and 9 who self-reported tobacco and/or supari use. Intervention schools received six sessions of LifeFirst, a psychosocial group-based tobacco cessation intervention program, in addition to SuperArmy, a school-wide life-skills and tobacco-prevention program. Trained counselors facilitated the cessation intervention, which spanned five months. All students in comparison schools received only SuperArmy. The outcome measures were self-reported use of tobacco-only, supari-only, and tobacco plus supari in the past 30 days. RESULTS The number of all users decreased by 19.1% in the intervention and 18.7% in the comparison schools at post-test. Although this reduction was significant (p<0.001) within each group, the difference between intervention and comparison schools was not significant. Further segregation by type of product used showed that for tobacco-only users there was a non-significant increase of 1.7% in intervention schools, and a significant 26.2% increase (p<0.001) in the comparison group. Tobacco plus supari use declined in both groups; however, supari-only use fell by 14.8% in the intervention and 32.7% in the comparison schools (p<0.01). CONCLUSIONS The combination of a cessation intervention along with the life-skills and tobacco-prevention program appear to have halted tobacco-only use in the intervention group. Future research needs to determine whether students are substituting supari for tobacco and to understand the psychological mechanisms underlying the cessation intervention and the interaction between cessation and prevention-only interventions.

Abstract
Preventing smoking among adolescents is critical. This study evaluated the effectiveness of the Smoking Prevention Education Program among nonsmoking adolescents. A quasi-experimental study design was used. Data were collected from Year 5 students ( n = 140) from four government primary schools in the Kuantan and Pahang districts of Malaysia. The participating schools were randomly assigned into the intervention and control groups. Questionnaires and exhaled carbon monoxide (CO) levels were used to collect data at the baseline and at 3 months postintervention. At 3 months postintervention, the percentage of nonsmokers remained 100% in the intervention group, while 2.9% of the participants in the control group reported to have smoked in past 7 days. Comparatively, the mean scores of attitudes, subjective norms, and nonsmoking intentions of the intervention group improved significantly. The intervention was effective in preventing smoking initiations among Malaysian adolescents; however, further evaluation of this intervention is needed among varied populations.

Abstract
Background Non-communicable diseases (NCDs) are the leading cause of death and disability worldwide, with low-income and middle-income countries experiencing a disproportionately high burden. Since 2010 WHO has promoted 24 highly cost-effective interventions for NCDs, dubbed ‘best buys’. It is unclear whether these interventions have been evaluated in low-income and lower-middle-income countries (LLMICs). Aim To systematically review research on interventions aligned to WHO ‘best buys’ for NCDs in LLMICs. Methods We searched 13 major databases and included papers conducted in the 83 World Bank-defined LLMICs, published between 1 January 1990 and 5 February 2015. Two reviewers independently screened papers and assessed risk of bias. We adopted a narrative approach to data synthesis. The primary outcomes were NCD-related mortality and morbidity, and risk factor prevalence. Results We identified 2672 records, of which 36 were included (608 940 participants). No studies on ‘best buys’ were found in 89% of LLMICs. Nineteen of the 36 studies reported on the effectiveness of tobacco-related ‘best buys’, presenting good evidence for group interventions in reducing tobacco use but weaker evidence for interventions targeting individuals. There were fewer studies on smoking bans, warning labels and mass media campaigns, and no studies on taxes or marketing restrictions. There was supportive evidence that cervical screening and hepatitis B immunisation prevent cancer in LLMICs. A single randomised controlled trial supported polypharmacy for cardiovascular disease. Fourteen of the ‘best buy’ interventions did not have any good evidence for effectiveness in LLMICs. Conclusions We found studies on only 11 of the 24 interventions aligned with the WHO ‘best buys’ from LLMIC settings. Most LLMICs have not conducted research on these interventions in their populations. LLMICs should take action to implement and evaluate ‘best buys’ in their national context, based on national priorities, and starting with interventions with the strongest evidence base.

Systematic review of universal school-based 'resilience' interventions targeting adolescent tobacco, alcohol or illicit substance use: A meta-analysis. Prev Med 2017; 100:248-268. [PMID: 28390835 DOI: 10.1016/j.ypmed.2017.04.003] [Citation(s) in RCA: 51] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2016] [Revised: 03/02/2017] [Accepted: 04/02/2017] [Indexed: 01/03/2023]
Abstract
Universal school-based interventions that address adolescent 'resilience' may represent a means of reducing adolescent substance use, however previous systematic reviews have not examined the effectiveness of such an intervention approach. A systematic review was undertaken to 1) assess whether universal school-based 'resilience' interventions are effective in reducing the prevalence of tobacco, alcohol or illicit substance use by adolescents, and 2) describe such effectiveness per intervention characteristic subgroups. Eligible studies were peer-reviewed reports (1994-2015) of randomised controlled trials including participants aged 5-18years that reported adolescent tobacco, alcohol or illicit substance use, and implemented a universal school-based 'resilience' intervention (i.e. those addressing both individual (e.g. self-esteem) and environmental (e.g. school connectedness) protective factors of resilience). Trial effects for binary outcomes were synthesised via meta-analyses and effect sizes reported as odds ratios. Subgroup (by intervention type, prevention approach, setting, intervention duration, follow-up length) and sensitivity analyses (excluding studies at high risk of bias) were conducted. Nineteen eligible studies were identified from 16,619 records (tobacco: n=15, alcohol: n=17, illicit: n=11). An overall intervention effect was found for binary measures of illicit substance use (n=10; OR: 0.78, 95%CI: 0.6-0.93, p=0.007,Tau2=0.0, I2=0%), but not tobacco or alcohol use. A similar result was found when studies assessed as high risk of bias were excluded. Overall intervention effects were evident for illicit substance use within multiple intervention characteristic subgroups, but not tobacco and alcohol. Such results support the implementation of universal school-based interventions that address 'resilience' protective factors to reduce adolescent illicit substance use, however suggest alternate approaches are required for tobacco and alcohol use.

Abstract
Purpose: Factors associated with ever-use and differences between ever-users and non-users of tobacco among adolescent school students from low income families in Mumbai were assessed. Materials and Methods: A self-administered questionnaire, completed by 1918 students from grades 7, 8 and 9 in 12 schools managed by the city municipal corporation in July 2015, gathered data on socio-demographic characteristics, tobacco use and tobacco-related knowledge, attitudes and beliefs. Results: Although only 1% of respondents thought tobacco was cool, nearly 35% were unaware of associations between tobacco use and health problems. Male students were almost twice as likely (OR=2.5, P <= 0.05) to have ever used tobacco compared to females and Supari (areca nut) users were eight times more likely (OR=8.99, P < 0.001) than Supari non -users. Tobacco-users were more likely to agree with statements: ‘People who use tobacco have more friends’ (OR=2.8, P = 0.004), ‘Smoking relieves stress’ (OR=5.6, P = 0.002) and ‘It is possible to purchase any tobacco product within 100 yards of school’ (OR=10.8, P < 0.001). Conclusion: This study highlights the gains made by tobacco prevention campaigns in that almost all students did not consider tobacco as cool or a stress reliever. However, they still need education about health consequences of tobacco-use. In addition, Supari use has to be addressed in school-based tobacco prevention and cessation initiatives. Furthermore, programs must also address perceptions and norms related to peers and tobacco use and ensure active implementation of existing laws. Such integrated measures will help ensure tobacco-free spaces around schools.

Abstract
To test the efficacy of an intervention to reduce tobacco use among youth (10-19 years old) in slum communities in Delhi, India. This community-based cluster-randomized trial included 14 slums composed of purposely built resettlement colonies and adjacent inhabitant-built Jhuggi Jhopris. Youth in the intervention received a 2 year multiple-component intervention: (a) youth and adult leader training; (b) peer-led interactive activities and outreach; (c) tobacco cessation camps; and (d) enforcement of India's Tobacco Control Law (smoke-free environments and youth access). Overall, no differences between the intervention and control conditions were observed over time; self-reported tobacco use declined in both groups. However, when stratified by type of residence, a significant decrease was observed among youth in the resettlement colonies in the intervention group for overall tobacco use (slope = -0.69) and cigarette and bidi smoking (slope = -0.66), compared to an increase in the control group (slope = 0.24 and 0.12, respectively) (P < 0.001). No differences in smokeless tobacco (SLT) use were observed for either group. Comprehensive community-based interventions that engage youth can be effective in reducing smoking among disadvantaged youth in India. More intensive interventions, like tax increases or large-scale media campaigns, appear warranted for the most marginalized in this context and for SLT products.

Abstract
BACKGROUND Tobacco control needs in India are large and complex. Evaluation of outcomes to date has been limited. AIM To review the extent of tobacco control measures, and the outcomes of associated trialled interventions, in India. METHODS Information was identified via database searches, journal hand-searches, reference and citation searching, and contact with experts. Studies of any population resident in India were included. Studies where outcomes were not yet available, not directly related to tobacco use, or not specific to India, were excluded. Pre-tested proformas were used for data extraction and quality assessment. Studies with reliability concerns were excluded from some aspects of analysis. The Framework Convention on Tobacco Control (FCTC) was use as a framework for synthesis. Heterogeneity limited meta-analysis options. Synthesis was therefore predominantly narrative. RESULTS Additional to the Global Tobacco Surveillance System data, 80 studies were identified, 45 without reliability concerns. Most related to education (FCTC Article 12) and tobacco-use cessation (Article 14). They indicated widespread understanding of tobacco-related harm, but less knowledge about specific consequences of use. Healthcare professionals reported low confidence in cessation assistance, in keeping with low levels of training. Training for schoolteachers also appeared suboptimal. Educational and cessation assistance interventions demonstrated positive impact on tobacco use. Studies relating to smoke-free policies (Article 8), tobacco advertisements and availability (Articles 13 and 16) indicated increasingly widespread smoke-free policies, but persistence of high levels of SHS exposure, tobacco promotions and availability-including to minors. Data relating to taxation/pricing and packaging (Articles 6 and 11) were limited. We did not identify any studies of product regulation, alternative employment strategies, or illicit trade (Articles 9, 10, 15 and 17). CONCLUSIONS Tobacco-use outcomes could be improved by school/community-based and adult education interventions, and cessation assistance, facilitated by training for health professionals and schoolteachers. Additional tobacco control measures should be assessed.

Abstract
BACKGROUND Helping young people to avoid starting smoking is a widely endorsed public health goal, and schools provide a route to communicate with nearly all young people. School-based interventions have been delivered for close to 40 years. OBJECTIVES The primary aim of this review was to determine whether school smoking interventions prevent youth from starting smoking. Our secondary objective was to determine which interventions were most effective. This included evaluating the effects of theoretical approaches; additional booster sessions; programme deliverers; gender effects; and multifocal interventions versus those focused solely on smoking. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Tobacco Addiction Group's Specialised Register, MEDLINE, EMBASE, PsycINFO, ERIC, CINAHL, Health Star, and Dissertation Abstracts for terms relating to school-based smoking cessation programmes. In addition, we screened the bibliographies of articles and ran individual MEDLINE searches for 133 authors who had undertaken randomised controlled trials in this area. The most recent searches were conducted in October 2012. SELECTION CRITERIA We selected randomised controlled trials (RCTs) where students, classes, schools, or school districts were randomised to intervention arm(s) versus a control group, and followed for at least six months. Participants had to be youth (aged 5 to 18). Interventions could be any curricula used in a school setting to deter tobacco use, and outcome measures could be never smoking, frequency of smoking, number of cigarettes smoked, or smoking indices. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed studies for inclusion, extracted data and assessed risk of bias. Based on the type of outcome, we placed studies into three groups for analysis: Pure Prevention cohorts (Group 1), Change in Smoking Behaviour over time (Group 2) and Point Prevalence of Smoking (Group 3). MAIN RESULTS One hundred and thirty-four studies involving 428,293 participants met the inclusion criteria. Some studies provided data for more than one group.Pure Prevention cohorts (Group 1) included 49 studies (N = 142,447). Pooled results at follow-up at one year or less found no overall effect of intervention curricula versus control (odds ratio (OR) 0.94, 95% confidence interval (CI) 0.85 to 1.05). In a subgroup analysis, the combined social competence and social influences curricula (six RCTs) showed a statistically significant effect in preventing the onset of smoking (OR 0.49, 95% CI 0.28 to 0.87; seven arms); whereas significant effects were not detected in programmes involving information only (OR 0.12, 95% CI 0.00 to 14.87; one study), social influences only (OR 1.00, 95% CI 0.88 to 1.13; 25 studies), or multimodal interventions (OR 0.89, 95% CI 0.73 to 1.08; five studies). In contrast, pooled results at longest follow-up showed an overall significant effect favouring the intervention (OR 0.88, 95% CI 0.82 to 0.96). Subgroup analyses detected significant effects in programmes with social competence curricula (OR 0.52, 95% CI 0.30 to 0.88), and the combined social competence and social influences curricula (OR 0.50, 95% CI 0.28 to 0.87), but not in those programmes with information only, social influence only, and multimodal programmes.Change in Smoking Behaviour over time (Group 2) included 15 studies (N = 45,555). At one year or less there was a small but statistically significant effect favouring controls (standardised mean difference (SMD) 0.04, 95% CI 0.02 to 0.06). For follow-up longer than one year there was a statistically nonsignificant effect (SMD 0.02, 95% CI -0.00 to 0.02).Twenty-five studies reported data on the Point Prevalence of Smoking (Group 3), though heterogeneity in this group was too high for data to be pooled.We were unable to analyse data for 49 studies (N = 152,544).Subgroup analyses (Pure Prevention cohorts only) demonstrated that at longest follow-up for all curricula combined, there was a significant effect favouring adult presenters (OR 0.88, 95% CI 0.81 to 0.96). There were no differences between tobacco-only and multifocal interventions. For curricula with booster sessions there was a significant effect only for combined social competence and social influences interventions with follow-up of one year or less (OR 0.50, 95% CI 0.26 to 0.96) and at longest follow-up (OR 0.51, 95% CI 0.27 to 0.96). Limited data on gender differences suggested no overall effect, although one study found an effect of multimodal intervention at one year for male students. Sensitivity analyses for Pure Prevention cohorts and Change in Smoking Behaviour over time outcomes suggested that neither selection nor attrition bias affected the results. AUTHORS' CONCLUSIONS Pure Prevention cohorts showed a significant effect at longest follow-up, with an average 12% reduction in starting smoking compared to the control groups. However, no overall effect was detected at one year or less. The combined social competence and social influences interventions showed a significant effect at one year and at longest follow-up. Studies that deployed a social influences programme showed no overall effect at any time point; multimodal interventions and those with an information-only approach were similarly ineffective.Studies reporting Change in Smoking Behaviour over time did not show an overall effect, but at an intervention level there were positive findings for social competence and combined social competence and social influences interventions.
