Nicotine and Cardiovascular Health: When Poison is Addictive - a WHF Policy Brief.

Nicotine is universally recognized as the primary addictive substance fuelling the continued use of tobacco products, which are responsible for over 8 million deaths annually. In recent years, the popularity of newer recreational nicotine products has surged drastically in many countries, raising health and safety concerns. For decades, the tobacco industry has promoted the myth that nicotine is as harmless as caffeine. Nonetheless, evidence shows that nicotine is far from innocuous, even on its own. In fact, numerous studies have demonstrated that nicotine can harm multiple organs, including the respiratory and cardiovascular systems. Tobacco and recreational nicotine products are commercialized in various types and forms, delivering varying levels of nicotine along with other toxic compounds. These products deliver nicotine in profiles that can initiate and perpetuate addiction, especially in young populations. Notably, some electronic nicotine delivery systems (ENDS) and heated tobacco products (HTP) can deliver concentrations of nicotine that are comparable to those of traditional cigarettes. Despite being regularly advertised as such, ENDS and HTP have demonstrated limited effectiveness as tobacco cessation aids in real-world settings. Furthermore, ENDS have also been associated with an increased risk of cardiovascular disease. In contrast, nicotine replacement therapies (NRT) are proven to be safe and effective medications for tobacco cessation. NRTs are designed to release nicotine in a slow and controlled manner, thereby minimizing the potential for abuse. Moreover, the long-term safety of NRTs has been extensively studied and documented. The vast majority of tobacco and nicotine products available in the market currently contain nicotine derived from tobacco leaves. However, advancements in the chemical synthesis of nicotine have introduced an economically viable alternative source. The tobacco industry has been exploiting synthetic nicotine to circumvent existing tobacco control laws and regulations. The emergence of newer tobacco and recreational nicotine products, along with synthetic nicotine, pose a tangible threat to established tobacco control policies. Nicotine regulations need to be responsive to address these evolving challenges. As such, governments should regulate all tobacco and non-medical nicotine products through a global, comprehensive, and consistent approach in order to safeguard tobacco control progress in past decades.

Programme and policy perspectives towards a tobacco-free generation in India: findings from a qualitative study.

OBJECTIVE: This study explored multistakeholder perspectives on existing adolescent-specific tobacco control policies and programmes, to advance India's transition towards a tobacco-free generation. DESIGN: Qualitative semi-structured interviews. SETTING: Interviews were conducted with officials involved in tobacco control at the national (India), state (Karnataka), district (Udupi) and village level. Interviews were audio recorded, transcribed verbatim and analysed thematically. PARTICIPANTS: Thirty-eight individuals representing national (n=9), state (n=9), district (n=14) and village (n=6) levels, participated. RESULTS: The study findings highlighted the need to strengthen and amend the existing Tobacco Control Law (2003) provisions, particularly in the vicinity of schools (Sections 6a and 6b). Increasing the minimum legal age to buy tobacco from 18 to 21 years, developing an 'application' for 'compliance and monitoring indicators' in Tobacco-Free Educational Institution guidelines were proposed. Policies to address smokeless tobacco use, stricter enforcement including regular monitoring of existing programmes, and robust evaluation of policies was underscored. Engaging adolescents to co-create interventions was advocated, along with integrating national tobacco control programmes into existing school and adolescent health programmes, using both an intersectoral and whole-societal approach to prevent tobacco use, were recommended. Finally, stakeholders mentioned that when drafting and implementing a comprehensive national tobacco control policy, there is a need to adopt a vision striving toward a tobacco-free generation. CONCLUSION: Strengthening and developing tobacco control programmes and policies are warranted which are monitored and evaluated rigorously, and where adolescents should be involved, accordingly.

The global impact of tobacco control policies on smokeless tobacco use: a systematic review.

BACKGROUND: Smokeless tobacco, used by more than 300 million people globally, results in substantial morbidity and mortality. For smokeless tobacco control, many countries have adopted policies beyond the WHO Framework Convention on Tobacco Control, which has been instrumental in reducing smoking prevalence. The impact of these policies (within and outside the Framework Convention on Tobacco Control) on smokeless tobacco use remains unclear. We aimed to systematically review policies that are relevant to smokeless tobacco and its context and investigate their impact on smokeless tobacco use. METHODS: In this systematic review, we searched 11 electronic databases and grey literature between Jan 1, 2005, and Sept 20, 2021, in English and key south Asian languages, to summarise smokeless tobacco policies and their impact. Inclusion criteria were all types of studies on smokeless tobacco users that mentioned any smokeless tobacco relevant policies since 2005, except systematic reviews. Policies issued by organisations or private institutions were excluded as well as studies on e-cigarettes and Electronic Nicotine Delivery System except where harm reduction or switching were evaluated as a tobacco cessation strategy. Two reviewers independently screened articles, and data were extracted after standardisation. Quality of studies was appraised using the Effective Public Health Practice Project's Quality Assessment Tool. Outcomes for impact assessment included smokeless tobacco prevalence, uptake, cessation, and health effects. Due to substantial heterogeneity in the descriptions of policies and outcomes, data were descriptively and narratively synthesised. This systematic review was registered in PROSPERO (CRD42020191946). FINDINGS: 14 317 records were identified, of which 252 eligible studies were included as describing smokeless tobacco policies. 57 countries had policies targeting smokeless tobacco, of which 17 had policies outside the Framework Convention on Tobacco Control for smokeless tobacco (eg, spitting bans). 18 studies evaluated the impact, which were of variable quality (six strong, seven moderate, and five weak) and reported mainly on prevalence of smokeless tobacco use. The body of work evaluating policy initiatives based on the Framework Convention on Tobacco Control found that these initiatives were associated with reductions in smokeless tobacco prevalence of between 4·4% and 30·3% for taxation and 22·2% and 70·9% for multifaceted policies. Two studies evaluating the non-Framework policy of sales bans reported significant reductions in smokeless tobacco sale (6·4%) and use (combined sex 17·6%); one study, however, reported an increased trend in smokeless tobacco use in the youth after a total sales ban, likely due to cross-border smuggling. The one study reporting on cessation found a 13·3% increase in quit attempts in individuals exposed (47·5%) to Framework Convention on Tobacco Control policy: education, communication, training, and public awareness, compared with non-exposed (34·2%). INTERPRETATION: Many countries have implemented smokeless tobacco control policies, including those that extend beyond the Framework Convention on Tobacco Control. The available evidence suggests that taxation and multifaceted policy initiatives are associated with meaningful reductions in smokeless tobacco use.

Impact of a tobacco sales ban on the frequency of tobacco consumption in India during the COVID-19 pandemic.

INTRODUCTION: Measures to address the COVID-19 pandemic in India included a ban on the sale and use of tobacco products during 2020 when stay at home guidance (lockdown) was in place. In this study we examined the extent of reduction in frequency of tobacco consumption across all products. METHODS: Telephone survey was conducted between July and August 2020 across an existing cohort of tobacco users (n=801) residing in Delhi (55.4%) and Chennai (44.6%), India. The participants were recruited irrespective of their gender and use of any kind of tobacco product(s). The survey questionnaire was based on the STOP (Studying Tobacco users Of Pakistan) survey and adapted to the context of smoking and smokeless tobacco use in India. RESULTS: Cigarette consumption declined from a median value of 5.0 (IQR: 2-10) sticks in the pre-lockdown period to 2.0 (IQR: 0.4-5) sticks during the lockdown period. Reductions were reported in the daily use of bidis, from 8 (IQR: 4-12) sticks to 5 (IQR: 2-10) sticks and for smokeless tobacco users from 3.5 (IQR: 2-5) packs to 2 (IQR: 1-4) packs during the lockdown. Furthermore, the number of daily cigarette smokers in our cohort decreased from 32.6% (n=261) in the pre-lockdown period to 27.5% (n=220) during lockdown and smokeless tobacco users decreased from 35.8% (n=287) in pre-lockdown period to 30.3% (n=243) during the lockdown period. CONCLUSIONS: The decrease in tobacco use can be attributed to various societal and environmental factors. However, the pandemic-linked lockdown provided an opportune condition to reduce the use of tobacco products, which could be due to restricted access and increase in health awareness during the COVID-19 lockdown.

Framework Convention on Tobacco Control 2030-A Program to Accelerate the Implementation of World Health Organization Framework Convention for Tobacco Control in Low- and Middle-Income Countries: A Mixed-Methods Evaluation.

BACKGROUND: Framework Convention on Tobacco Control (FCTC) 2030 Program (2017-2021) was launched to accelerate World Health Organization (WHO) FCTC implementation in 15 low- and middle-income countries (LMICs). We evaluated the Program in six domains: Governance; Smoke-Free Policies; Taxation; Packaging and Health Warnings; Tobacco Advertising, Promotion, and Sponsorship (TAPS) bans; and International and Regional Cooperation. AIMS AND METHODS: Following a mixed-methods design, we surveyed (June-September 2020) FCTC focal persons in 14 of the 15 countries, to understand the Program's financial and technical inputs and progress made in each of the six domains. The data were coded in terms of inputs (financial = 1, technical = 1, or both = 2) and progress (none = 1, some = 2, partial = 3, or strong = 4) and a correlation was computed between the inputs and progress scores for each domain. We conducted semi-structured interviews with key stakeholders in five countries. We triangulated between the survey and interview findings. RESULTS: FCTC 2030 offered substantial financial and technical inputs, responsive to country needs, across all six domains. There was a high positive correlation between technical inputs and progress in five of the six domains, ranging from r = 0.61 for taxation (p < .05) to r = 0.91 and for smoke-free policies (p < .001). The interviews indicated that the Program provided timely and relevant evidence and created opportunities for influencing tobacco control debates. CONCLUSIONS: The FCTC 2030 Program might have led to variable, but significant progress in advancing FCTC implementation in the 15 countries. As expected, much of the progress was in augmenting existing structures and resources for FCTC implementation. The resulting advances are likely to lead to further progress in FCTC policy implementation. IMPLICATIONS: What this study adds: In many LMICs, WHO FCTC policies are not in place; and even when enshrined in law, they are poorly enforced. It is not clear how financial and technical assistance to high tobacco-burden LMICs can most effectively accelerate the implementation of WHO FCTC policies and offer value for money. Bespoke and responsive assistance, both financial and technical, to LMICs aimed at accelerating the implementation of WHO FCTC policies are likely to lead to progress in tobacco control.

Common assumptions in tobacco control that may not hold true for South-East Asia.

Tobacco is a threat to public health in South-East Asia and its control should be a priority. However, many common assumptions about tobacco control may not hold true for the region and can misdirect policy. The substantial health risks associated with smokeless tobacco have been largely misunderstood and neglected. The syndemic association between tuberculosis and tobacco has also been overlooked. Similarly, less attention has been paid to address second-hand smoke exposure of pregnant women to indoor smoking (caused predominantly by men). On the other hand, our poor understanding of the diverse tobacco supply chain has been blocking progress in tobacco control. Finally, the rising popularity of electronic cigarettes has thrown new challenges; many governments, concerned for its youth, have banned such products. We argue for a nuanced approach to tobacco control in South-East Asia. We also encourage a wider debate in public health, where other established assumptions may be hampering progress.

Accelerating policy response to curb non-communicable diseases: an imperative to mitigate the dual public health crises of non-communicable diseases and COVID-19 in India.

Non-communicable Diseases (NCDs) are a threat to public health and sustainable development. NCDs were equated to being a 'pandemic' before COVID-19 originated. Globally, NCDs caused approximately 74% of deaths (2019). India accounted for nearly 14.5% of these deaths. NCDs and COVID-19 have a lethal bi-directional relationship with both exacerbating each other's impact. Health systems and populations, particularly in Low- and Middle-Income Countries (LMICs) like India have among the highest burden of COVID-19. This narrative review tracks key policy and programmatic developments on NCD prevention and control in India, with a focus on commercially-driven risk factors (tobacco and alcohol use, unhealthy diet, physical inactivity, and air pollution), and the corresponding NCD targets. It identifies lacunae and recommends urgent policy-focussed multi-dimensional action, to ameliorate the dual impact of NCDs and COVID-19. India's comprehensive response to NCDs can steer national, regional and global progress towards time-bound NCD targets and NCD-related Sustainable Development Goals (SDGs).

Socio-Economic Status Differences in Changing Affordability of Tobacco Products from 2011-2012 to 2018-2019 in India.

INTRODUCTION: We studied the change in affordability of tobacco products, an important determinant of tobacco use, across the different socio-economic status (SES) in India. AIMS AND METHODS: We calculated affordability in the form of relative income price (RIP-cost of tobacco products relative to income) for the years 2011-2012 and 2018-2019 using three different denominators, that is per capita gross domestic product (GDP) and net state domestic product at national and state levels, respectively; monthly per capita consumer expenditure (MPCE); and individual wages. We investigated RIP for cigarettes, bidis, and smokeless tobacco (SLT) across different SES groups (caste groups, type of employment, and education). RESULTS: RIP increased marginally for cigarettes, bidis and remained almost constant for SLT across casual workers. However, when RIP was adjusted with SES variables, there was no significant change (p > .05) in the affordability of products for casual workers in the year 2018-2019 as compared to 2011-2012. For regular workers, cigarettes and bidis became marginally less affordable (ß < 1), whereas affordability remained constant for SLT. All products became more affordable for backward caste groups within regular workers. When RIP was calculated using MPCE all tobacco products became less affordable in the year 2018-2019. However, after adjusting for SES variables SLT reported no change in affordability. There was a marginal increase in affordability for all products when RIP was calculated with GDP. CONCLUSIONS: Although implementation of GST has increased the price of tobacco products, it is still not sufficient to reduce the affordability of tobacco products, particularly SLT and especially for the lower SES group. IMPLICATIONS: Tobacco use and economic disadvantage conditions of the population are intricately linked. Affordability of tobacco products is influenced by socio-economic indicators like age, sex, income, education, etc. The literature measuring the affordability of tobacco products across different SES groups is scant in India. Additionally, existing literature measures affordability of tobacco products based on per capita GDP as a proxy for income. This is the first study in Indian context to report the change in affordability of tobacco products across different SES groups after adjusting for SES indicators, using individual-level income data. We have calculated the change in affordability of tobacco products between the year 2011-2012 and 2018-2019 using GDP, household income, and individual wages as a proxy for income.

Changes in tobacco depictions after implementation of tobacco-free film and TV rules in Bollywood films in India: a trend analysis.

BACKGROUND: India's tobacco-free film and TV rules were implemented from 2012. To assess the effect of the rules, we studied tobacco depictions in top-grossing Bollywood films released between 2006 and 2017 and rule compliance after 2012. METHODS: Tobacco incidents and brand appearances were coded in 240 top-grossing Bollywood films (2006-2017) using the Breathe California method. Trends in number of tobacco incidents per film per year were studied before and after implementation of the rules using Poisson regression analysis. Compliance with rules over the years was studied using Pearson product-moment correlations. RESULTS: Forty-five films were U-rated (all ages), 162 were UA-rated (below age 12 years must be adult-accompanied), and 33 were A-rated (age 18+ years only). Before implementation of the rules, the number of tobacco incidents per film was increasing by a factor of 1.1/year (95% CI 1.0 to 1.2, p=0.002). However, beginning year 2013, the number of incidents per film started falling significantly by a factor of 0.7/year (95% CI 0.6 to 0.9; p=0.012) compared with the previous increasing trend. The percentage of youth-rated (U and UA) films with any tobacco incidents also declined from a peak of 76% in 2012 to 35% in 2017. The percentage of films complying with the rules (audio-visual disclaimers, health spots, static warnings) did not change significantly from 2012 to 2017. CONCLUSION: India's 2012 rules were followed by a reduction in tobacco depictions in Bollywood films. Enhanced monitoring of compliance is needed to ensure the continued effectiveness of the rules.

Association of Hypertensive Disorders of Pregnancy (HDP) and tobacco use among women of reproductive age group in India: A secondary data analysis from NFHS-4.

Introduction: Tobacco use in any form is known to exert several perinatal complications. Through this study, the authors aimed to study the association between tobacco use and Hypertensive Disorders of Pregnancy (HDP) among women (aged 15-49 years) in India. Methodology: We used data from the National Family Health Survey (NFHS-4, 2015-2016) to study the association between tobacco use and HDP among women of reproductive age (15-49 years) in India. Since the NFHS follows a complex multi-level sampling, sampling weights were used to study the univariate and multivariate associations between the independent and dependent variables. Adjusted odds ratios (AORs) are reported along with 95% Confidence Intervals. Results: A sample of 1,07730 women was included in the analysis. HDP was more likely to be experienced by smokeless and smoking tobacco users (AOR 1.3, 95% CI (1.0-1.6) and AOR 2.7, 95% CI (2.0-3.7), respectively). Women with secondary (AOR 0.7, 95% CI (0.7-0.8)) and higher education (AOR 0.7, 95% CI (0.6-0.8)) were less likely to suffer from HDP as compared to those with no education. Women with daily (AOR 0.7, 95% CI (0.5-0.8)), weekly (AOR 0.8, 95% CI (0.6-0.9)) or occasional AOR 0.7, 95% CI (0.6-0.9)) consumption of fruits were less likely to experience HDP as compared to women with no fruit intake. Conclusion: Healthy diet and lifestyle factors can contribute to reduce the risk of HDP across women. The antenatal check-ups in India should also comprehensively focus on screening and counseling of women against tobacco use.

The Impact of Alcohol Consumption on Cardiovascular Health: Myths and Measures.

Over the past several decades, the prevalence of cardiovascular disease (CVD) has nearly doubled, and alcohol has played a major role in the incidence of much of it. Alcohol has also been attributed in deaths due to infectious diseases, intentional and unintentional injuries, digestive diseases, and several other non-communicable diseases, including cancer. The economic costs of alcohol-associated health outcomes are significant at the individual as well as the country level. Risks due to alcohol consumption increase for most cardiovascular diseases, including hypertensive heart disease, cardiomyopathy, atrial fibrillation and flutter, and stroke. The widespread message for over 30 years has been to promote the myth that alcohol prolongs life, chiefly by reducing the risk of coronary heart disease (CHD). Lack of universal advice and stringent policy measures have contributed towards increased uptake and easy availability of alcohol. The WHO has called for a 10% relative reduction in the harmful use of alcohol between 2013-2025. However, lack of investment in proven alcohol control strategies, as well as persistence of misinformation and industry interference, have hindered the efforts of public health professionals to make sufficient progress in reducing alcohol related harms and death.

Anxiety and depression among adult tobacco users during the COVID-19 restrictions in India.

Background: The world witnessed a highly contagious and deadly disease, COVID-19, toward the end of 2019. India is one of the worst affected countries. We aimed to assess anxiety and depression levels among adult tobacco users and people who recently quit tobacco during COVID-19 lockdown in India. Materials and methods: The study was conducted across two Indian cities, Delhi and Chennai (July-August, 2020) among adult tobacco users (n = 801). Telephonic interviews were conducted using validated mental health tools (Patient Health Questionnaire-PHQ-9 and Generalized Anxiety Disorder-GAD-7) to assess the anxiety and depression levels of the participants. Descriptive analysis and multiple logistic regression were used to study the prevalence and correlates of depression and anxiety. Results: We found that 20.6% of tobacco users had depression symptoms (3.9% moderate to severe); 20.7% had anxiety symptoms (3.8% moderate to severe). Risk factors associated with depression and anxiety included food, housing, and financial insecurity. Conclusion: During COVID-19 lockdown, mental health of tobacco users (primarily women) was associated with food, housing and financial insecurity. The Indian Government rightly initiated several health, social and economic measures to shield the most vulnerable from COVID-19, including a ban on the sale of tobacco products. It is also necessary to prioritize universal health coverage, expanded social security net, tobacco cessation and mental health services to such vulnerable populations during pandemic situations.

Netarsudil-induced corneal honeycombing in childhood glaucomas.

Netarsudil is a hypotensive drug that reduces intraocular pressure (IOP). Although it is used to treat corneal decompensation/edema in normotensive eyes, we observed the occurrence of corneal epithelial edema with corneal honeycombing in children with uncontrolled IOP (primary or secondary glaucoma) on maximal topical medication following netarsudil (0.02%) therapy of >2 weeks. Of 16 eyes of 16 children, 9 (56%) developed corneal honeycombing. They were younger than those without honeycombing (median age, 3.1 vs 9.7 years [P = 0.016]), had higher baseline IOP (35.6 ± 7.4 vs 27.2 ± 5.6 mm Hg [P < 0.001]), and usually had preexisting corneal edema (7/9 eyes vs none [P < 0.001]).

Intracameral vent and flush technique for silicone oil blockade in Ahmed glaucoma valve.

The presence of emulsified silicone oil in the eye can lead to many complications, glaucoma being one of the most common. Adequate IOP control is difficult to achieve with medical management alone; surgical intervention is often required. Glaucoma drainage device implantation is often the preferred line of surgical intervention in such cases due to trabeculectomy failure from emulsified silicone oil droplets and associated conjunctival scarring. However, the silicone tube of Ahmed glaucoma valve (AGV) may attract the silicone oil droplets, causing blockade of the tube with persistent raised IOP postoperatively. We report one such case where post-AGV silicone oil tube occlusion was treated with semi-conservative surgical management instead of revising the entire surgery or implantation of another drainage device. Our surgical technique of intracameral "vent and flush" offers rapid and effective IOP control in such cases. Postoperatively, normal IOP was achieved. Patency of tube continued to be maintained along with normalization of IOP on subsequent follow-ups.

Understanding the dynamics of notification and implementation of Article 5.3 across India's states and union territories.

INTRODUCTION: In federal systems, state and local governments may offer opportunities for innovation in implementing the WHO Framework Convention on Tobacco Control (FCTC). This paper explores the implementation of WHO FCTC Article 5.3 within India's federal system, examining how its guidelines have been operationalised across states and union territories. METHODS: Interviews with officials from government and civil society organisations across key states, and a document review of state government and district administration notifications adopting Article 5.3 guidelines between 2015 and 2019. RESULTS: The data reveal subnational leadership in formulating intersectoral committees, which are designed to limit interactions with the tobacco industry, and corresponding measures to reject partnership and conflicts of interest for government officials. There are notable omissions across states and union territories in adoption of key Article 5.3 guidelines; only four districts and state governments refer to regulating aspects of 'socially responsible' industry activities, and no notifications include measures to prevent the tobacco industry receiving preferential treatment or requiring that information provided by industry actors be transparent and accountable. Interview data indicate that dynamics of notification across states have been shaped by lesson drawing and the catalytic role of civil society. The adoption of protocols is impacting on the practices of health officials, but there are concerns about engagement by other departments and the regulatory capacity of empowered committees. CONCLUSION: The spread of state- and district-level policies illustrates opportunities federal structures can provide for accelerating tobacco control. Given significant omissions and policy tensions, there remains a need for national action to build on these innovations, including in revisions to India's tobacco control legislation.

Potential Risk Factors of Smokeless Tobacco Consumption Among Adolescents in South India.

INTRODUCTION: Although most of the disease burden internationally is due to tobacco smoking, smokeless tobacco (SLT) use contributed to an estimated 76 000 deaths in 2017. We have studied the potential risk factors for SLT use among adolescents in South India. METHODS: A cross-sectional questionnaire survey of all students in grades 6-8 in schools in the Udupi district of Karnataka State ascertained SLT use status and potential determinants of SLT uptake. Ever SLT use was defined as any reported consumption of any SLT products, currently or at any time in the past. Independent effects on ever SLT use status were estimated using multiple logistic regression. RESULTS: Of 46 706 students from 914 participating schools, 39 282 (84.1%) provided questionnaire responses sufficiently complete for analysis. Ever SLT use was reported by 775 (2.0%) participants and in a mutually adjusted model was significantly related to age, male sex, family use, or friend's use of SLT, low socioeconomic status, high rebelliousness, and low self-esteem. After controlling for these effects, the odds of ever-SLT use were significantly higher among students who had least awareness of the harmful effects of tobacco use (odds ratio 3.7, 95% confidence interval [2.9, 4.7]) and significantly lower among those not exposed to tobacco advertising (odds ratio 0.7, 95% confidence interval [0.5, 0.8]). CONCLUSIONS: The prevalence of SLT use among children in Karnataka is relatively low when compared with other studies in India. The significant potential risk factors of SLT use include low awareness of the harmful effects of tobacco and tobacco control policies and exposure to tobacco advertising. IMPLICATIONS: The prevalence of SLT use among school going adolescents in South India is relatively low. The potential risk factors for SLT use among adolescents in southern India are similar to those for smoked tobacco. It includes age, male gender, family or friend's use of SLT, low socioeconomic status, high rebelliousness, low self-esteem, exposure to tobacco advertisement and least awareness about the harmful effects of tobacco and of tobacco control policies. The present study lays emphasis regarding creating awareness about tobacco harms and control policies for further reducing tobacco use among adolescents.

Knowledge, attitude, and behaviours on diet, physical activity, and tobacco use among school students: A cross-sectional study in two Indian states.

Background: Non-communicable diseases (NCDs) are escalating in India and can be attributed to behavioural risk factors such as unhealthy diet, physical inactivity and tobacco use that began in early years. Understanding adolescents' knowledge, attitudes and behaviours (KAB) related to NCD risk factors would inform the development of school-based health programmes to prevent NCDs. Methods: Sixth-grade students (n=1026) in 20 schools (10 private, 10 public) from two Indian cities (n=667 from Pune; n=359 from Bengaluru) participated in a KAB survey in 2019. Differences in KAB by gender, school type within cities were investigated. Results: Knowledge about the harms of tobacco use was higher than knowledge about a healthy diet and the importance of physical activity. Only a small proportion of students did not eat breakfast (8.7%) or fruits (11.3%) daily. Only 33.4% of students read nutrition labels before choosing their food. Moderate-to-vigorous physical activity of less than an hour per day was reported by 42.5% of students. Approximately one-third of students had ever tried smoking tobacco (30.1%), smokeless tobacco (30.5%), and e-cigarettes (32.4%). Differences in these behaviours by gender and school type showed that both boys, girls and students of private and public schools are vulnerable. Conclusions: The findings highlight that knowledge is low for thematic areas like diet and physical activity. Low knowledge can be attributed to unfavourable behaviours like lack of reading nutrition labels and indulgence in sedentary activities. To protect India's young population (adolescents), there is a need to amplify health education activities and context-specific health intervention materials for them by engaging parents and communities. Thus, these programmes should be incorporated into the curriculum as part of the regular teaching, as they may induce positive changes in their knowledge and behaviours. In India, school health programmes should dedicate significant time to health promotion and NCD risk prevention.
