ABSTRACT

BACKGROUND: Obesity is a metabolic syndrome where allelic and environmental variations together determine the susceptibility of an individual to the disease. Caloric restriction (CR) is a nutritional dietary strategy recognized to be beneficial as a weight loss regime in obese individuals. Preconceptional parental CR is proven to have detrimental effects on the health and development of their offspring. As yet studies on maternal CR effect on their offspring are well established but paternal CR studies are not progressing. In current study, the impact of different paternal CR regimes in diet-induced obese male Wistar rats (WNIN), on their offspring concerning metabolic syndrome are addressed. METHODS: High-fat diet-induced obese male Wistar rats were subjected to caloric restriction of 50% (HFCR-I) and 40% (HFCR-II) and then they were mated with normal females. The male parent's reproductive function was assessed by sperm parameters and their DNMT's mRNA expression levels were also examined. The offspring's metabolic function was assessed by physiological, biochemical and molecular parameters. RESULTS: The HFCR-I male parents have shown reduced body weights, compromised male fertility and reduced DNA methylation activity. Further, the HFCR-I offspring showed attenuation of the AMPK/SIRT1 pathway, which is associated with the progression of proinflammatory status and oxidative stress. In line, the HFCR-I offspring also developed altered glucose and lipid homeostasis by exhibiting impaired glucose tolerance & insulin sensitivity, dyslipidemia and steatosis. However, these effects were largely mitigated in HFCR-II offspring. Regarding the obesogenic effects, female offspring exhibited greater susceptibility than male offspring, suggesting that females are more prone to the influences of the paternal diet. CONCLUSION: The findings highlight that HFCR-I resulted in paternal undernutrition, impacting the health of offspring, whereas HFCR-II largely restored the effects of a high-fat diet on their offspring. As a result, moderate caloric restriction has emerged as an effective weight loss strategy with minimal implications on future generations. This underscores the shared responsibility of fathers in contributing to sperm-specific epigenetic imprints that influence the health of adult offspring.

ABSTRACT

BACKGROUND: Chronic respiratory diseases are disorders of the airways and other structures of the lung, and include chronic obstructive pulmonary disease (COPD), lung cancer, asthma, bronchiectasis, interstitial lung diseases, occupational lung diseases and pulmonary hypertension. Through this article we take a broad view of chronic lung disease while highlighting (1) the complex interactions of lung diseases with environmental factors (e.g. climate change, smoking and vaping) and multimorbidity and (2) proposed areas to strengthen for better global patient outcomes. CONCLUSION: We suggest new directions for the research agenda in high-priority populations and those experiencing health disparities. We call for lung disease to be made a research priority with greater funding allocation globally.

ABSTRACT

BACKGROUND AND OBJECTIVES: The tobacco industry (TI) has undermined tobacco control policy for decades. The WHO Framework Convention on Tobacco Control Article 5.3 implementation guidelines provide guidance for preventing TI interference. Government officials responsible for policy implementation must understand these guidelines to manage TI tactics. This study assessed awareness, attitudes and practices of Article 5.3 guidelines among members of District Level Coordination Committees (DLCC) in Karnataka mandated with overseeing tobacco control activity. METHOD: A semistructured questionnaire survey of awareness, attitudes and adherence to Article 5.3 guidelines among 102 DLCC members carried out between January and July 2019. RESULT: Responses were received from 82 members, comprising 51 (62%) from health and 31 (38%) from non-health departments. Our study demonstrates a lack of understanding of Article 5.3 and its guidelines, even among those actively involved in tobacco control at the district level. Nearly 80% of respondents were aware that corporate social responsibility (CSR) by tobacco companies is an indirect form of promoting tobacco. However, 44% of members felt that CSR funding from the TI should be used to combat tobacco-related harm. A higher proportion (12%) of health respondents agreed that subsidies should be provided to tobacco agriculture compared with non-health (3%). CONCLUSION: Awareness of international guidance designed to prevent the TI influence on health policy among policymakers in this Indian state is low. Respondents from non-health departments were less aware of TI CSR. Those in health departments were more receptive towards taking a TI role in the future .

ABSTRACT

The body of a deceased human and 4 deceased cats were found in a house while a fire was being extinguished. As a result of these findings, arson, homicide, and animal death investigations were opened. As part of the animal death investigation, all of the cats were submitted for veterinary forensic autopsies. All cats had soot on the fur and had soot deposits within the oral cavity, esophagus, and respiratory tract. Two cats had soot within the stomach. Cardiac blood was analyzed for carboxyhemoglobin using a CO-oximeter, and all cats had levels >65%. The cause of death was determined to be due to toxic smoke inhalation from the structure fire. Case findings support the potential use of CO-oximeter for determination of carboxyhemoglobin levels in cats and continued research in this area of forensic practice.

ABSTRACT

SUMMARY: Noncommunicable diseases (NCDs) pose a significant global health and economic burden, necessitating universal health coverage (UHC). Out-of-pocket (OOPs) payments for healthcare, particularly in low- and middle-income countries lacking social protection and health insurance, contribute to impoverishment and catastrophic expenditure. This scoping review aimed to assess the state of UHC for NCDs in India, including the progress made, coverage of government health insurance schemes, challenges faced, and their potential solutions. A literature search was performed in major databases such as PubMed, Ovid, Web of Science, Embase, Cochrane Library, and Google Scholar using appropriate keywords. Findings indicated that UHC remains a distant dream in India with a disproportionately high NCD burden and a substantial portion of health-care expenses (80% outpatient, 40% inpatient) relying on OOP expenditures, causing financial hardship. Limited universal social security exacerbates health-care access challenges. The coronavirus disease-2019 pandemic has further hindered NCD services and UHC progress. The Ayushman Bharat program, featuring health and wellness centers and the Pradhan Mantri Jan Arogya Yojana, aims to address primary health-care needs and provide NCD coverage in India. Despite this, challenges persist, including inadequate availability of essential medicines and technologies in health-care facilities, as well as gaps in rural health-care access. Telemedicine services like "eSanjeevani" have been implemented to improve access in remote areas. To achieve UHC for NCDs in India, it is crucial to strengthen primary health-care, ensure medicine availability, enhance human resources, establish a referral system, address social determinants, and implement social protection.

ABSTRACT

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.

ABSTRACT

INTRODUCTION: Accelerating progress on tobacco control will require Article 5.3 of the WHO Framework Convention on Tobacco Control to be systematically integrated into policies and practices of sectors beyond health at diverse government levels. However, no study has explored implementation challenges of Article 5.3 within multilevel systems such as India, where political decisions on tobacco control occur at diverse government levels, which may constrain action at local level. METHODS: Based on 33 semi-structured interviews with diverse government and civil society stakeholders across four districts in Karnataka, India (Mysore, Mangalore, Bengaluru (rural) and Udupi), this study examines challenges to implement Article 5.3 arising from competing agendas and policies of different actors at multiple levels. RESULTS: Our analysis reveals generally low levels of awareness of Article 5.3 and its guideline recommendations, even among those directly involved in tobacco control at district level. Efforts to implement Article 5.3 were also challenged by competing views on the appropriate terms of engagement with industry actors. Scope to reconcile tensions across competing health, agriculture and commercial agendas was further constrained by the policies and practices of the national Tobacco Board, thereby undermining local implementation of Article 5.3. The most challenging aspect of Article 5.3 implementation was the difficulties in restricting engagement by government officials and departments with tobacco industry corporate social responsibility initiatives given national requirements for such activities among major corporations. CONCLUSIONS: Promoting effective implementation of Article 5.3 in Karnataka will require policymakers to work across policy silos and reconcile tensions across India's national health and economic priorities.

ABSTRACT

INTRODUCTION: In September 2014, the Government of India introduced legislation requiring all tobacco packaging to display a health warning covering 85% (60% pictorial, 25% text) of the principal display area of the pack, of at least 4 cm in height and 3.5 cm width, with legible text in a white font on a black background and in English and/or the same Indian language as the language used on the pack. We evaluated compliance with this legislation in the Udupi district of Karnataka, India. METHODS: We procured one example of every tobacco pack of cigarettes, beedis, chewing tobacco, and snuff sold by a convenience sample of retailers in one urban and two rural areas in each of the five administrative blocks of the Udupi district between June and August 2018. For each pack we measured the size of the health warning, calculated the proportion of the pack covered, and assessed the legibility. RESULTS: A total of 365 packs were collected from retailers, with 357 of these branded and eight, all packs of snuff, unbranded. Warnings on 320 (87.3%) packs did not reach the legally required proportional magnitude, warnings on 140 (38.4%) packs were not legible, and warnings on 117 packs (32.1%) did not meet the language requirement. Only 45 packs (12.3%) were fully compliant. CONCLUSIONS: Compliance with warning legislation in this district of India is low, highlighting the need for more effective enforcement. IMPLICATIONS: Warnings on tobacco packaging are an important and inexpensive means of communicating the harms associated with tobacco use. However, relatively few studies have explored regulatory compliance with warnings. We collected all unique tobacco packs from 66 retailers in a district in Karnataka in India and assessed whether each met the legislative requirements in terms of warning size and proportion of the pack covered, legibility, and the language used. Of the 365 packs collected, only one in eight was compliant with the legislative requirements. This study highlights the importance of assessing warning compliance and the need for enforcement in India.

ABSTRACT

BACKGROUND: Exposure to smoking in films is a recognised cause of smoking uptake among children. In India, in an attempt to protect children, films containing smoking are required to include tobacco control messaging including audiovisual disclaimers, on-screen health warnings when tobacco imagery is displayed and antitobacco 'health spots' before and during the film. We report a study of the association between ever smoking and exposure to tobacco imagery in locally popular films among children in Udupi district of Karnataka state in southern India. METHODS: A cross-sectional questionnaire survey of all students in grades 6-8 in schools in the Udupi district ascertained smoking status and potential confounders of smoking uptake, and whether children had seen any of 27 locally popular films we had coded and found to contain imagery of actual or implied tobacco use. Ever-smoking status was defined as any reported smoking of cigarettes, beedis or other tobacco products currently or at any time in the past. Independent effects on ever-smoking status were estimated using multiple logistic regression. RESULTS: Of 46 706 students enrolled in grades 6-8 in 914 participating schools, 39 282 (84.1%) provided questionnaire responses sufficiently complete for analysis. Ever smoking was reported by 914 (2.3%) participants and in a mutually adjusted model was significantly related to age, male sex, living in a home where smoking is allowed, having parents or siblings who smoke, low paternal education, low levels of family wealth, low self-esteem, rebelliousness and poor school performance. After allowing for these effects, the odds of ever smoking were not increased among students who had seen any of the listed films containing tobacco imagery when included in the analysis as a binary exposure (OR 0.9, 95% CI 0.4 to 2.0), and decreased in relation to level of exposure graded into tertiles of tobacco intervals seen. CONCLUSIONS: In this cross-sectional study, children in southern India who had seen films containing tobacco imagery are no more likely to smoke than those who had not, indicating that the tobacco control messaging mandated by Indian law may be attenuating the effect of tobacco imagery in films on smoking uptake.

ABSTRACT

BACKGROUND: India is currently facing a rising epidemic of Non-Communicable Diseases (NCDs). Identification of modifiable risk factors is of paramount importance to curb this menace. Fishermen are one of the most vulnerable occupational groups with unique characteristics that make them prone to acquire NCDs, as a significant share of their life is spent at sea. Hence, this study was planned to ascertain the burden of NCDs, determine various risk factors of NCDs, and measure the association between risk factors and NCDs among fishermen of Coastal Karnataka in South India. METHODS: A cross-sectional study was conducted among 681 fishermen aged 18 years and above as per the semi-structured interview schedule for two years (2017-2019). A convenience sampling strategy was adopted. The data was entered and analyzed using SPSS v.15.0. The results were described in terms of proportions and their 95% confidence intervals. Continuous data were summarized using the mean and standard deviation or median and interquartile range depending on the skewness of data. Chi-square test was used to study the association between NCDs and modifiable risk factors. Multiple logistic regression was used to identify risk factors of NCDs. RESULTS: The mean (SD) age of the population was 42.5 (SD 12.5) years. The mean years involved in fishing was 19.8 years (SD 10.9). More than half (59.5%) of the study participants had severe stress and most (80.3%) were ever substance users. Advancing age, not being able to contact family while at sea, poor dietary practice, ever substance use, increasing waist circumference were significant correlates of NCDs. CONCLUSIONS: The commonly prevalent risk factors of NCDs among fishermen included poor dietary practice, higher stress levels, substance use, increasing waist circumference, and inability to contact with family while at sea. Hypertension and Diabetes were the two common NCDs in the study population. There is a need for immediate attention in managing NCDs' risk factors by promoting a healthy lifestyle by primary health care providers through a sustainable community awareness program targeting fishermen at a convenient time and location, either at the sea-port or meeting places. Harmful effects of substance use, healthy dietary practices, and the importance of physical activity outside their job need emphasis. In addition, screening programs should be organized with the help of boat owners and fishing associations at-least once a year to pick up NCDs at an early stage.

ABSTRACT

The lockdown on account of the Coronavirus disease 2019 (COVID-19) adversely impacted the food production sector including aquaculture, globally. Unfortunately, it coincided with the major shrimp farming season in India which contributes 60% of the national annual shrimp production hence the impact was substantial. An on-line survey was carried out among the stakeholders of the shrimp farming sector to evaluate the prospective impact of COVID-19 related lockdown across the shrimp supply chain. The study estimated an economic loss of 1.50 billion USD to the shrimp aquaculture sector during the current year. It is expected that shrimp production and its export performance may be declining by 40% in the current season. The Garret ranking and Rank Based Quotient analyses projected severe constraints in shrimp seed production and supply, disruptions in the supply chain, logistics, farming, processing, marketing and loss of employment and income for the workers due to the pandemic. To mitigate the impact, the Government of India declared fisheries and aquaculture as an essential activity, facilitated the movement of inputs and services. Further, a major Fisheries Development Scheme(PMMSY) with a financial outlay of 267 million USD has been announced to usher in a blue revolution by strengthening the value chain, doubling the fisher/farmer income, employment generation, economic and social security for fishers/fish farmers adhering to the sustainability principles. Short and medium-term technical and policy measures are suggested to tide over the impact of COVID-19 related lockdown and related restrictions.

ABSTRACT

BACKGROUND: Exposure to smoking in films causes smoking uptake among adolescents. Investigation of the extent to which tobacco imagery appears, or tobacco control laws are complied with in Indian films is limited, and especially so for films in regional languages. This study presents an analysis of tobacco content and compliance with tobacco control laws in popular films in several languages from the Karnataka state of India. METHODS: We used 5 min interval coding to measure actual tobacco use, implied tobacco use, tobacco paraphernalia and tobacco branding in the top 10 films identified from national box office ratings and regional distributor reports in Karnataka in 2015 and 2016. We also assessed compliance with tobacco-free film rules in India. FINDINGS: A total of 47 films, in English, Hindi, Malayalam, Tamil, Telugu and Tulu languages were coded. Any tobacco imagery was observed in 72% of films, and actual tobacco use in 50%. Tobacco imagery was equally prevalent in films classified as suitable for universal viewing (U category) or at age 12 or more (U/A category) films; and significantly more common in films made in regional than national language (Hindi). None of the films were fully compliant with legal requirements on health spots, audiovisual disclaimers and health warnings. CONCLUSIONS: Tobacco content was common in films classified as suitable for viewing by children, more among regional than national languages. Compliance with tobacco control laws was low. Stricter enforcement of tobacco-free film rules will protect children and adolescents from exposure to tobacco use on screen.

ABSTRACT

BACKGROUND: Diabetic foot is one of the most significant and devastating complication of diabetes. The objective of this study was to assess the prevalence of diabetic foot syndrome (DFS) and the associated risk factors among people with diabetes mellitus. METHODS: A community based cross-sectional study was carried out among 620 subjects with diabetes mellitus (DM) in rural areas of Udupi district. The Michigan Neuropathy Screening Instrument was used to identify peripheral neuropathy. Ankle brachial index was used to identify peripheral arterial disease (PAD). Subjects with diabetic foot syndrome were classified according to the International Working Group on Diabetic Foot (IWGDF) classification system. RESULTS: The overall prevalence of DFS was 51.8%. Among them 31.3, 11.9 and 8.5% belonged to category 1, 2 and 3 respectively. Multivariate logistic regression analysis showed advancing age, low socio-economic status, sedentary physical activity and longer duration of DM were significant independent correlates of DFS. CONCLUSION: The overall prevalence of DFS was high among the study population; hence the screening for foot complications should start at the time of diagnosis of diabetes integrated with sustainable patient education at primary care level by training of health care providers at primary care level.

ABSTRACT

Obesity is a multifactorial disorder associated with increased body adiposity, chronic oxidative stress which contributes to impaired fertility in males. Diet restriction and anti-oxidant supplementations are known to protect obese subjects from oxidative stress and improves fertility. However, the role of oxidative stress and the age of intervention in restoring male fertility are poorly understood. This study was aimed to assess the effect of diet restriction on fertility with respect to the age of intervention, body composition and oxidative stress using WNIN/Ob obese mutant rat strain. Unlike lean and carrier phenotypes, obese rats are hyperphagic, hyperlipaemic and infertile. Male obese rats aged for 35, 60 and 90 days were fed either ad libitum or diet restricted for 6 weeks. Upon diet restriction mean body weight, total body fat percentage, circulatory lipids and oxidative stress markers were significantly reduced and it follows the order as 35 < 60 < 90 days. Diet-restricted males of the three age groups were allowed to mate with female carrier rats, and fertility was restored only in 35-day group. Diet restriction in male obese WNIN/Ob rats lowered the rate of body weight gain, with reduced oxidative stress overall and fertility restoration in groups intervened at pre-pubertal stages.

ABSTRACT

The present study examined the complex interaction among stocking density and extent of probiotic use with production and environmental parameters in Litopenaeus vannamei culture ponds to suggest suitable management strategies. The study was conducted inL. vannamei culture ponds with stocking density of 35 nos sq m(-1) (Group I) and 56 nos sq m(-1) (Group II) and probiotic application @16.5 kg ha(-1) and 157 kg ha(-1), respectively. There was no significant difference noted between the two groups of ponds in respect to ammonia oxidizing bacteria (AOB) in sediment and nitrite oxidizing bacteria (NOB) in water samples, whereas significantly higher levels of AOB in water samples of high intensity culture ponds (Group II) and NOB in sediment samples of Group I were observed. The levels of sulphur oxidizing bacteria (SOB) and sulphur reducing bacteria (SRB) in Group I pond water and in Group II sediment were significantly higher than their corresponding levels in the other group. In both the groups, ammonia, nitrite and sulphide concentrations were below toxic limits prescribed for shrimp farming. Comparing the production parameters at harvest revealed that low intensity culture ponds (Group I) had higher growth rate, average body weight and significantly lower FCR and higher survival rate than high intensity culture ponds (Group II). The results indicated that application of microbial products in higher quantities did not benefit significantly, and there is a need to regulate quantum and schedule of biological product usage for economically sustainable shrimp culture.

ABSTRACT

BACKGROUND: Tobacco use is associated with early, intermediate and long-term complications throughout the life course. With an influx of newer products containing nicotine, poly-tobacco use is slowly emerging as a public health concern, that is defined as existing tobacco users currently using two or more tobacco or nicotine products. While many studies have investigated single use tobacco, there is a paucity of research on regional patterns and socio-demographic factors associated with poly-tobacco use in India. OBJECTIVES: To assess prevalence of poly-tobacco use and determine the socio-demographic factors associated with poly-tobacco use in India. METHODS: Data from the Global Adult Tobacco Survey 2 (GATS, 2016-17) was analysed, which included information on tobacco use among people aged >15 years. The pattern of current tobacco status was described using descriptive statistics. Multiple logistic regression models were estimated to determine factors associated with poly-tobacco use. RESULTS: The prevalence of poly-tobacco use in India was found to be 9.8%. Among the current tobacco users, the prevalence was 33%. Significant socio-demographic factors associated with poly-tobacco use included younger age, male gender, religion and backward caste. North-eastern region reported highest prevalence of poly-tobacco use in the country, followed by the central region. CONCLUSION: The number of poly-tobacco users in India is considerably high and a matter of concern, more so in north east and central regions of the country. There is a need to create awareness about dangerous effects of all types of tobacco products and strengthen implementation of tobacco control policies with special focus on regions with high burden.

ABSTRACT

INTRODUCTION: India has unique tobacco-free film and TV rules designed to prevent tobacco uptake. In this study, we examined the potential influence of exposure to smoking imagery in regionally famous films, on susceptibility to smoke in teenagers enrolled in schools in a district in Southern India. METHODS: A longitudinal survey of students, in grades 6 to 8 at baseline in 2017 and grades 7 to 9 one year later in 2018, ascertained prospective incident susceptibility to smoking during the study period in relation to baseline exposure to 27 locally popular films with actual or implied smoking imagery. RESULTS: We analyzed linked data from 33676 participants, and 3973 (11.8%) of the adolescents reported incident susceptibility. There was a significant increase in susceptibility to smoking with increasing exposure at baseline to smoking imagery in films on univariable analysis, highest tertile of exposure relative to no exposure (OR=1.4; 95% CI: 1.0 -2.1, ptrend<0.001), and this trend remained significant (p=0.022) after mutual adjustment for recognized confounders, highest vs no exposure (AOR=1.3; 95% CI: 0.9-1.8). We found no statistically significant association between exposure to tobacco-free film rules and change in susceptibility. CONCLUSIONS: Prospectively, watching films featuring smoking imagery increases adolescents' vulnerability to smoking. Further research revealed no difference in susceptibility change between youth who saw partially compliant films and those who watched non-compliant films. Our findings, thus, underscore the need to incorporate comprehensive approaches to prevent the inclusion of smoking imagery in films.

ABSTRACT

Progress in the mass production of newly developed bulk (Gd0.33Y0.13Er0.53)Ba2Cu3Oy "(Gd,Y,Er)123" and MgB2 systems is presented. Two batches of (Gd,Y,Er)123 pellets of 20 mm diameter and 7 mm thick were prepared in air by an infiltration growth "IG" process. Trapped field distribution profiles of fully grown bulk samples clearly showed that all samples were single-grain and the trapped field values were more than 0.5 T at 77 K, 1.3 mm above top surface. The best bulk exhibited the trapped field value of 0.63 T at 77 K. Ultra-sonication technique was employed for refining precursors of both (Gd,Y,Er)211 and boron. TEM studies revealed that boron powder subjected to ultrasonication was refined up to nanoscale. The micron-sized particles were reduced to nanoscale, which led to improvement of critical current by up to 36% in bulk MgB2 at 20 K and self-field. This progress in fabrication of high-performance LREBa2Cu3Oy and MgB2 superconducting bulks further promotes commercialization of superconductors' production as a mode of sustainable technology.

ABSTRACT

INTRODUCTION: In India there is insufficient knowledge of the risks associated with tobacco use. Increasing awareness of these risks is critical, with pictorial warnings on tobacco packs a cost-effective way to communicate this information. We explored perceptions of the current warning, 'Tobacco causes cancer', displayed on packs in India and four novel warnings about other potential impacts of tobacco use including social, financial, and environmental, but also complications with diabetes. As loose cigarette sales are common in India, we also explored perceptions of warnings on cigarette sticks. METHODS: A cross-sectional survey of college students aged ≥18 years in Karnataka, India, was conducted between January 2019 and February 2020. Participants were asked about salience, believability, and cognitive processing of warnings currently on packs. They were then shown an image of one current and four novel warnings and asked about their perceived effectiveness in preventing uptake and reducing and stopping tobacco use. They were then asked about warnings on cigarette sticks. RESULTS: Most participants (70.2%) recalled warnings on packs and considered them believable (55.7%), but only 12.0% read and 12.4% thought about them often. Warnings about the health impacts of tobacco use were viewed as most effective in preventing uptake, and reducing and stopping tobacco use. Nevertheless, at least a third of participants rated warnings pertaining to financial, social, and environmental impacts effective in preventing uptake, and reducing and stopping tobacco use. Approximately one-fifth (22.0%) thought that warnings on cigarette sticks would deter initiation. CONCLUSIONS: Our results suggest that health warnings are perceived as most effective in discouraging tobacco use among college students in Karnataka. While viewed as less effective than health warnings, novel non-health related messages were viewed as effective in preventing uptake, and reducing and stopping tobacco use by at least one in three participants. Warnings on cigarette sticks may help complement warnings on cigarette packs.

ABSTRACT

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.
