Socioeconomic inequality in the prevalence of smoking and smokeless tobacco use in India

Trends in smokeless tobacco use and attributable mortality and morbidity in the South-East Asia Region: implications for policy

OBJECTIVES

To describe the prevalence of smokeless tobacco (SLT) use and number of users by year, in addition to trends in mortality and attributable disease burden in countries of the WHO South-East Asia Region (SEAR), to inform policies for SLT control in the Region.

METHODS

For each SEAR country, we obtained data from Global Adult Tobacco Surveys, WHO STEPwise Approach to NCD Risk Factor Surveillance surveys and Demographic and Health Surveys conducted since 2010 to estimate prevalence of SLT use by country, sex and year. Using data from the World Population Prospects database we estimated the number of users by country. Next, using the results of previous meta-analyses and prevalence results, we estimated the population attributable fractions and attributable mortality and morbidity in terms of annual deaths and disability-adjusted life years lost. We then characterised trends in attributable deaths and disease burden for countries with comparable data.

RESULTS

There were wide differences in SLT use prevalence by country. We estimated that, during 2015-2019, there were 165 803 900 SLT users across SEAR, with 479 466 attributable deaths annually of which India accounted for 79.9% with 383 248. Attributable annual deaths increased in some countries during 2015-2019.

CONCLUSIONS

Annual deaths and disease burden attributable to SLT remain high across SEAR and have only declined modestly in recent years. Effective implementation of all WHO Framework Convention on Tobacco Control measures, addressing both supply-side and demand-side issues, in relation to SLT and areca nut products must be prioritised to ensure reductions in mortality and disease burden are sustained and accelerated.

Split household and smoking behaviour of rural migrants in China

OBJECTIVES

This study aimed to address the direct impact of split households on smoking behaviour. Three types of spilt households (sole migration, couple migration, and family migration) were incorporated to explore the concise effect of different split household forms. This study also examined factors that contributed to the narrowing gap in smoking prevalence between 2008 and 2018.

STUDY DESIGN

Retrospective observational study.

METHODS

Data were obtained from the Rural Urban Migration (RUMiC-2009) and China Household Income Project (CHIP2018). Analyses were conducted using chi-squared tests/analysis of variance tests and multiple logit regression. The order probit model with sample selection was conducted to correct for selection bias. Fairlie decomposition was used to quantify the contribution of individual variables to the observed differences in smoking prevalence.

RESULTS

Smoking prevalence for all migrants decreased by 5.79% between 2008 and 2018. The results in 2008 reveal the positive and significant contribution of couple migration (coefficient = -0.4608; 95% CI = [-0.6453, -0.2762]) and family migration (coefficient = -0.3705; 95% CI = [-0.5959, -0.1452]) on the reduction of smoking; the finding for family migration remained robust in 2018. Measurable factors partially explain the decline in smoking disparity. The migration of families, working in the construction and manufacturing industries, and educational attainment were the largest contributing factors to the declining gap in smoking prevalence.

CONCLUSIONS

The increase in family migration and education, and decrease in the number of workers in the construction and manufacturing industries, contributed to a decrease in smoking prevalence. Public policies should target sole migrants, couple migrants, individuals with lower education levels, and those working in the construction and manufacturing industries.

Gendered Pattern and Predictors of Tobacco use in India: Evidence from the Second Round of Global adult Tobacco Survey

Background

India has completed the second round of the Global Adult Tobacco Survey (GATS) to monitor adult tobacco use and progress in tobacco control efforts. This study assesses the gendered pattern of tobacco use and its predictors in the second rounds of GATS.

Material and Methods

Publicly available GATS-2 (2016-2017) data was analyzed which contains self-reported tobacco use information of ≥15 years Indians (n = 74,037). The independent predictors of "smoking only," "smokeless only," and "dual use" among current male and female tobacco users were assessed using the multinomial regression model.

Results

The burden of "smoking only," "smokeless only," and "dual-use" of tobacco were 8.9% (8.74-9.15), 16.69% (16.42-16.96), and 3.89% (3.75-4.03), respectively, in the second round with wide regional variation as well as male dominance in use. Region, age, education, caste, and religion were significantly and consistently associated with different types of tobacco use in both genders. Other contextual predictors of tobacco use were residence, marital status, occupation, awareness, and wealth index (WI).

Conclusions

Tobacco use predictors and their gendered patterns are contextual. Monitoring the predictors for tobacco use, which may change over time, should be given priority in the national tobacco control program.

Socioeconomic inequalities in tobacco cessation among Indians above 15 years of age from 2009 to 2017: evidence from the Global Adult Tobacco Survey (GATS)

BACKGROUND

Tobacco is strongly associated with socioeconomic status (SES), however evidence on differences in tobacco cessation by socio-economic attributes remains fragmented, especially in developing countries. The present study aims to estimate socioeconomic inequalities in tobacco cessation among Indian men and women above 15 years of age.

METHODS

Two rounds of the Global Adult Tobacco Survey (2009-2010 and 2016-2017), India was used to estimate the association between socioeconomic indicators (wealth index and educational attainment) with tobacco cessation using a multinomial modeling approach.

RESULTS

After adjusting for SES and demographic variables, we found significantly lower odds in tobacco cessation rates among respondents of GATS-2 (2016-2017) compared to GATS-1 (2009-2010). Additionally, huge regional variations in smoking and smokeless tobacco cessation rates were observed. Population belonging to the low wealth-asset score had higher odds of cessation compared to the high asset index. While greater educational attainment was seen to have a positive effect on cessation, the results were insignificant. Individuals belonging to the northeastern geographic region were seen to have the lowest odds of cessation. Though awareness about the health hazards of tobacco increased, cessation declined for both men and women. Quitting smokeless tobacco among men and women was observed to be lower than smoking.

CONCLUSION

This study is the first to provide national-level evidence on the association between tobacco cessation and socioeconomic attributes among Indians above 15 years of age. Findings suggest the need to scale up tobacco cessation services separately for men and women, and also for smoking and smokeless tobacco forms.

Impact of tobacco price and taxation on affordability and consumption of tobacco products in the South-East Asia Region: A systematic review

INTRODUCTION

The objective of the review was to study the impact of tobacco taxes or prices on affordability and/or consumption of tobacco products in WHO South-East Asia Region (SEAR) countries, overall and by socioeconomic status; and change in consumption of one tobacco product for a given change in price/tax on another tobacco product.

METHODS

The searches were made in five databases (Medline, Embase, Cinahl, EconLit, Tobacconomics) using keywords such as 'tobacco', 'tax', 'price', 'impact' with their synonyms. Additionally, the first 100 articles through google search and e-reports from targeted sources were also reviewed. Studies illustrating the impact of prices/taxes on consumption/affordability of tobacco products in SEAR, in English and with no limitation on year, were included in the review. After two steps of screening, data from 28 studies were extracted using a structured and pre-tested data extraction form.

RESULTS

Of the 28 studies, 12 studies reported an inverse association between price and consumption/affordability, while 11 studies reported no or positive association between price and consumption/affordability of tobacco products. Five studies had unclear interpretations. The majority of studies estimated that the less affluent group were more price responsive compared to the more affluent group. Some studies indicated increased consumption of one product in response to price rise of another product, although, the findings were inconsistent.

CONCLUSIONS

The findings of our review support the use of tobacco tax and price measures as effective tools to address the tobacco epidemic. Our findings, however, also emphasize the importance of increasing tobacco product taxes and prices sufficiently to outweigh the effects of income growth, in order for the measures to be effective in reducing the affordability and consumption of tobacco products.

Socioeconomic inequalities in tobacco smoking in women aged 15-54 in Iran: a multilevel model

Significant evidence suggests an inverse relationship between socioeconomic status and tobacco smoking, where inequality is visible among different social and economic strata. The aim of this study was to investigate the prevalence and economic and social inequalities in tobacco smoking in women aged 15-54 in Iran. This study is a cross-sectional study. Sampling in this study was a randomized clustered multistage sampling with equal clusters. A total of 35,305 women aged 15-55 enrolled in the study. Data analysis was in two stages. In the first stage, the social and economic inequalities were investigated using the concentration index and concentration curve method, and in the second method, and multilevel method was used to identify the determinants. The prevalence of tobacco smoking in women was 12.24%. The concentration index for smoking was CI = -0.07 [95% CI (-0.09, -0.05)], which represents smoking in people with low socioeconomic status. The results of the multilevel analysis indicated that the marital status of people over the age of 35 and the economic class was related to smoking in women. Inequality in tobacco smoking in women is to the interest of the well-off group, and this inequality varies in different provinces. Marital status, place of residence, age and socioeconomic status of women are factors influencing the prevalence of tobacco smoking in women, and these issues should be noticed to reduce inequalities.

Declining trend of smoking and smokeless tobacco in India: A decomposition analysis

There has been a relative reduction of tobacco consumption between Global Adult Tobacco Survey-India (GATS-India) 2009–10 and GATS-India 2016–17. However, in terms of absolute numbers, India still has the highest number of tobacco consumers. Therefore, this paper aims to examine the socioeconomic correlates and delineate the factors contributing to a change in smoking and smokeless tobacco use from GATS (2009–10) to GATS (2016–17) in India. We used multivariable binary logistic regressions to examine the demographic and socioeconomic correlates of smoking and smokeless tobacco use for both the rounds of the survey. Further decomposition analysis has been applied to examine the specific contribution of factors in the decline of tobacco consumption over a period from 2009 to 2016. Results indicated that the propensity component was primarily responsible for major tobacco consumption decline (smoking- 41%, smokeless tobacco use- 81%). Most of the decrease in propensity to smoke has been explained by residential type and occupation of the respondent. Age of the respondent contribute significantly in reducing the prevalence of smokeless tobacco consumption during the seven-year period, regardless of change in the composition of population. To achieve the National Health Policy, 2017 aim of reducing tobacco use up to 15% by 2020 and up to 30% by 2025, targeted policies and interventions addressing the inequalities identified in this study, must be developed and implemented.

Tobacco smoking and risk of all-cause mortality in Indonesia

Tobacco is well known as a risk factor for early morbidity and mortality worldwide. However, the relative risk of mortality and the effects of smoking vary among the countries. Indonesia, as one of the world's largest market for smoking tobacco, is significantly affected by tobacco-related illness. Previous research has shown that smoking causes several diseases, including stroke, neoplasm and coronary heart disease. There has to date been no research on the hazard risk of smoking for all-cause mortality in Indonesia. This study aimed to identify the association between smoking and all-cause mortality rates in Indonesia. Information from a total of 3,353 respondents aged 40 years and older was collected in this study. The data were taken from the Indonesian Family Life Survey (IFLS) Wave 4 (2007) to collect personal information and determine smoking status and from Wave 5 (2015) to collect information about deaths. Current smokers make up 40.3% of Indonesia's population. Current smokers were more likely to have a higher risk of all-cause death (hazard ratio = 1.48, 95% confidence interval = 1.11 to 1.98) than non-current smokers. The number of smokers in Indonesia remains high and is expected to increase gradually every year. A firm government policy is needed to reduce the number of smokers in Indonesia which would automatically reduce the health problem of smoking-related illness in the future.

Pattern and Predictors of Tobacco Use in India: Evidence from National Family Health Survey (2015–2016)

Tobacco use continues to be of research interest due to the significant amount of tobacco-attributable non-communicable diseases and deaths in India. This study examines the pattern and predictors of smoking, chewing, and any tobacco use among adults of age 15–49 years in India. This study used secondary data from the fourth round of the National Family and Health Survey (NFHS, 2015–2016) which collected information on tobacco use from men and women in the age group 15–49 ( n = 803097). Bivariate and multivariate analyses were conducted to understand the socio-economic and demographic predictors. GIS maps have been used to show inter-state variation in smoking, chewing, and any tobacco use by gender. About one out of every ten adults aged 15–49 use any tobacco, predominantly in chewing forms. Women are significantly less likely to smoke (odds ratio [OR]: 0.05, confidence interval [CI]: 0.04–0.05), chew (OR: 0.25, CI: 0.24–0.25), and use any tobacco (OR: 0.14, CI: 0.13–0.14) compared with men. Tobacco usage was found more common among the uneducated and economically weak people. There is considerable inter-state heterogeneity in the prevalence and type of tobacco use, and adults in the north-east region are among the most vulnerable population subgroups. Tobacco use continues to be a significant burden due to its magnitude and different forms of use in India. The higher use among males, illiterates, economically weak, socially backward and alcohol users suggest the need for targeted efforts to improve their knowledge and awareness about the harmful effects of tobacco use and stronger enforcement of tobacco control policies.

Dependence on smokeless tobacco and willingness to quit among patients of a tertiary care hospital of Bhavnagar, Western India

BACKGROUND

There is a paucity of data on smokeless tobacco (SLT) use in Bhavnagar city of western India. This research attempts to find out the dependence and willingness to quit SLT use.

MATERIALS AND METHODS

This was a hospital-based cross-sectional study conducted in a tertiary care government hospital on a calculated sample size of 258 SLT users in the year 2017. The patients were recruited from ear-nose-throat (ENT) and dental outpatient department (OPD). The tobacco dependence was assessed using "Fagerstrom Test for Nicotine Dependence-SLT" and willingness to quit was assessed on a Likert scale of 1-10.

RESULTS

Among the 258 SLT users, 20% were highly dependent on SLT and 61% had low willingness to quit tobacco. "Mawa" was the most common (60%) chewed form of tobacco. Illiterate patients were three times more likely and patients whose occupation required traveling were 2.4 times more likely to develop high dependence for SLT than their counterparts. Patients living in the joint family were 2.7 times more likely to develop high dependence than patients living in a nuclear family.

CONCLUSION

There is a need for the introduction of tobacco cessation interventions in ENT and dental OPD of tertiary care hospitals of western India.

Correlates of tobacco quit attempts and missed opportunity for tobacco cessation among the adult population in India

INTRODUCTION

Tobacco cessation is crucial to reduce tobacco-related diseases and premature deaths. Quitting efforts can be enhanced through brief routine interventions at health facilities because healthcare providers are highly trusted, resulting in stronger adherence to their advice.

MATERIALS AND METHODS

This study used data on tobacco users aged 15-49 years (n = 93,522) collected as part of the fourth round of the National Family Health Survey (NFHS) 2015-16. Bivariate and multivariate analyses were carried out using STATA (version 13) to understand the socioeconomic and demographic correlates of tobacco quit attempts and advice to quit by healthcare providers. GIS map has been used to show inter-state variations in quit attempts and advice.

RESULTS

Thirty per cent of the tobacco users were found to have attempted to quit tobacco. Education, mass media exposure, economic status, and chronic disease emerged as enablers, while alcohol use and social backwardness came out as barriers to quit attempts. Quit advice from the healthcare providers was found not to be given frequently (51%) and varied significantly by the socioeconomic and demographic profile of the users. Not all of the tobacco users attempting to quit had been advised to quit, indicating a missed opportunity to intervene and reinforce quitting at a health facility.

CONCLUSIONS

Fewer attempts to quit among the adolescents, the less educated, and the users from the poorest households may increase the burden of tobacco-attributable diseases unless timely interventions are made. Better training of the healthcare providers in administering and recommending tobacco cessation and emphasizing on the value of cessation counselling is urgently required to enhance quitting practices and improve health.

Smokeless Tobacco Warnings in Indian Mass Media: Intention and Attempts to Quit

Introduction: In India, over 200 million people use smokeless tobacco (SLT), which increases the risk of cancers. Studies have demonstrated mass media campaigns effectively reduce smoking tobacco prevalence, but few have assessed their impact on SLT cessation. Objectives: This study used data from the Global Adult Tobacco Surveys (GATS) in 2009–2010 and 2016–2017 to examine associations between SLT health warnings in mass media, and intention and attempts to quit using SLT. We also compared the proportion of SLT users who noticed mass media warnings between 2009–2010 and 2016–2017. Materials and Methods: Over 16,000 and 15,000 current SLT users from the GATS-1 and GATS-2, respectively, were used for analysis. Weighted logistic regression models were used to analyze associations between noticed health warnings on SLT packages, newspapers/magazines, television, radio, billboards, cinemas, internet, vehicles, and walls, and intention and attempts to quit SLT. Results: In final models, the odds of intention and attempts to quit were highest among those who noticed warnings in newspapers/magazines (adjusted odds ratio [AOR]: 1.50; 95% confidence interval [CI]: 1.30–1.74) and the internet (AOR: 1.60; 95% CI: 1.12–2.29), respectively. Warnings on SLT packages, television, billboards, radio, vehicles, and walls were also associated with increased cessation behavior. More noticed warnings on SLT packages, television, billboards, and newspapers/magazines in GATS-2 than GATS-1, but fewer heard radio warnings. Conclusions: Among Indian SLT users, we found evidence that SLT warnings in mass media may promote cessation behavior. Health warnings in mass media could play an important role in the overall strategy to reduce the morbidity and mortality associated with SLT use.

Socio-economic inequalities in smoking prevalence and involuntary exposure to tobacco smoke in Argentina: Analysis of three cross-sectional nationally representative surveys in 2005, 2009 and 2013

BACKGROUND

Understanding patterns of socio-economic inequalities in tobacco consumption is key to design targeted public health policies for tobacco control. This study examines socio-economic inequalities in smoking and involuntary exposure to tobacco smoke between 2005 and 2013.

METHODS

Data were derived from the Argentine National Risk Factors Surveys, conducted in 2005, 2009, and 2013. Two inequality measures were calculated: the age-adjusted prevalence ratio (PR) and the disparity index (DI). Educational level, household income per consumer unit and employment status were used as proxies for socio-economic status (SES). Generalized linear models were used in the analysis.

RESULTS

Prevalence of smoking decreased from 29.7% to 25.1% between 2005 and 2013, mainly in women (p<0.001). Despite the overall prevalence reduction, socio-economic inequalities in smoking persisted. For both men and women, the DI was moderately high for smoking (14.47%-33.06%) across the three surveys. In men, the PR indicated a higher smoking prevalence for lower educational levels and lower household income throughout the analyzed period. In women, unlike previous years, the 2013 survey showed disparity related to unemployment. Involuntary exposure to tobacco smoke in 2013 was associated with educational level and household income, with lower involuntary exposure among those with higher SES.

CONCLUSIONS

While overall smoking rates have decreased in Argentina, socio-economic disparities related to tobacco smoking persist. Comprehensive tobacco control programs targeted to address these inequalities are essential in developing strategies to reduce health disparities in tobacco-related diseases.

Socio-demographic inequalities in cigarette smoking in Indonesia, 2007 to 2014

The prevalence of smoking in Indonesia is one of the highest in the world. Since 2007, some tobacco control policies have been implemented by the Indonesian government. However, evidence on the effectiveness of such policies at reducing tobacco use in Indonesia is scarcely available. Using both cross-sectional and longitudinal analysis of individual and household data from two waves of the Indonesia Family Life Survey (IFLS), this study explored changes in smoking patterns among Indonesian adults between 2007 and 2014 controlling for sociodemographic factors. Overall, there was no statistically significant change in the prevalence of smoking between 2007 and 2014. However, cigarettes became more affordable. Smokers in 2014 consumed more cigarettes (β: 0.95; 0.73, 1.17) and spent more money on cigarettes (β: IDR 2775; IDR 1124, IDR 4426) compared to those in 2007. Males, individuals <55 years old and those with lower levels of education had a higher likelihood of being smokers in 2014. Respondents with lower education levels and those under 26 years of age had higher odds of initiating smoking during the study period. Similarly, smoking cessation between 2007 and 2014 was more likely among respondents with higher levels of education and aged above 40 years. In conclusion, the implementation of tobacco control measures does not appear to have had a positive impact on smoking behaviours among adults in Indonesia between 2007 and 2014. Instead, cigarette consumption increased differentially across socio-demographic groups. Hence, tailored tobacco control interventions targeting the most socially disadvantaged population may be necessary in Indonesia.

Clinical management of type 2 diabetes in south Asia

Compared with other ethnic groups, south Asian people with type 2 diabetes tend to develop the disease at a younger age and manifest with higher glycaemia, dyslipidaemia, nephropathy, and cardiovascular diseases. Additionally, specific issues that can affect treatment of type 2 diabetes in south Asia include poor awareness of the disease, delay in diagnosis, inadequate treatment, the use of ineffective and often harmful alternative medicines, and frequent non-compliance with lifestyle recommendations and drug treatment. Disease development at younger ages, delayed diagnosis, and inadequate management result in early development of severe complications and premature mortality. In this Series paper, we describe the challenges associated with the increasing burden of type 2 diabetes in south Asia and discuss ways to improve clinical care of people with the disorder in the region (defined to include Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka). Treatment of diabetes in south Asia needs to be individualised on the basis of diverse and heterogeneous lifestyle, phenotype, environmental, social, cultural, and economic factors. Aggressive management of risk factors from diagnosis is necessary to reduce the risk of microvascular and macrovascular complications, focusing on provision of basic treatments (eg, metformin, low-cost statins, and blood pressure-lowering drugs) and other interventions such as smoking cessation. Strengthening of the primary care model of care, better referral linkages, and implementation of rehabilitation services to care for patients with chronic complications will be important. Finally, improvement of physicians' skills, provision of relevant training to non-physician health-care workers, and the development and regular updating of national clinical management guidelines will also be crucial to improve diabetes care in the region.

Socioeconomic Inequality in Concurrent Tobacco and Alcohol Consumption

Background:

Whilst several studies have examined inequity of tobacco use and inequity of alcohol drinking individually, comparatively little is known about concurrent tobacco and alcohol consumption. The present study therefore investigated inequity of concurrent tobacco and alcohol consumption in Thailand.

Methods:

The 2015 Health and Welfare Survey was obtained from Thailand’s National Statistical Office and used as a source of national representative data. Concurrent tobacco and alcohol consumption was defined as current and concurrent use of both tobacco and alcohol. The wealth assets index was used as an indicator of socioeconomic inequity. Socioeconomic status included 5 groups ranging from poorest (Q1) to richest (Q5). A total of 55,920 households and 113,705 participants aged 15 years or over were included and analyzed. A weighted multiple logistic regression was performed.

Results:

The prevalence of concurrent tobacco and alcohol consumption, tobacco consumption only, and alcohol consumption only were 15.2% (95% CI: 14.9, 15.4), 4.7% (95% CI: 4.5, 4.8), and 18.9% (95% CI: 18.7, 19.1), respectively. Weighted multiple logistic regression showed that concurrent tobacco and alcohol consumption was high in the poorest socioeconomic group (P for trend <0.001), and tobacco consumption only was also high in the poorest group (P for trend <0.001). A high prevalence of alcohol consumption was observed in the richest group (P for trend <0.001).

Conclusions:

These findings suggest that tobacco and alcohol consumption prevention programs would be more effective if they considered socioeconomic inequities in concurrent tobacco and alcohol consumption rather than focusing on single drug use.

Trends in socioeconomic inequalities among adult male hardcore smokers in Vietnam: 2010-2015

BACKGROUND

Despite male smokers being dominant in Vietnam, scarce evidence on trends in socioeconomics inequalities among the hardcore male smokers is available in the country. In this study, we aimed at assessing the trends in socioeconomics inequalities among the hardcore smokers in adult male population in Vietnam over a five-year period from 2010 to 2015.

METHODS

We used data from two rounds of the Vietnam Global Adult Tobacco Survey (GATS) conducted in 2010 and 2015. We included only men aged 25 years and above in the analysis. We measured socioeconomic inequalities among hardcore smokers by calculating the concentration index. We conducted multiple logistic regression analysis to identify factors associated with hardcore smoking among men aged 25 years and above.

RESULTS

The results of this study showed that the prevalence of male hardcore smokers aged 25 years and above in Vietnam was 9.5% in 2010 which increased to 13.1% in 2015. The prevalence of male hardcore smokers declined in the richest group from the 2010 level whereas it increased in the middle, poor and poorest groups. All values of weighted concentration indices indicated that the prevalence of male hardcore smokers occurred more among the poor men in Vietnam in both 2010 and 2015. The socioeconomic inequalities in hardcore smokers increased during 2010 and 2015. Residence in urban areas was significantly associated with higher adult male hardcore smoking in our study. Belonging to the age groups between 40 and 59 years, attaining primary and lower education, being self-employed, belonging to the poorest household group, smoking being allowed at home and no rule for smoking at home were associated with higher risk of being hardcore smoker among adult males in Vietnam.

CONCLUSIONS

We found increased trends in socioeconomic inequalities in hardcore smoking among the study population. Our study results indicate that existing smoking secession and tobacco control policy and interventions need to be modified or new policies and interventions should be introduced with the perspective of addressing socioeconomic inequalities to have the desired impact. We recommend implementing specific targeted interventions for vulnerable population groups for better results.

Pattern of tobacco use and its correlates among older adults in India

PURPOSE

We examined tobacco use pattern and its correlates among older adults.

MATERIALS AND METHODS

We used data of 9,852 older adults (>=60 years) (men 47% mean age 68 years) collected by the United Nations Population Fund on Ageing from seven Indian states. Logistic regression analysis was used to assess the correlates of tobacco use.

RESULTS

Current use of any form of tobacco was reported by 27.8% (men 37.9%, women 18.8%); 9.2% reported only smoking tobacco, 16.9% smokeless tobacco only and 1.7% used both forms. Alcohol users (OR:5.20, 95% CI:4.06-6.66), men (OR:2.92, CI :2.71-3.47), those reporting lower income (OR:2.74, CI:2.16- 3.46), rural residents (OR 1.34, CI 1.17-1.54) and lower castes (OR:1.29, CI:1.13-1.47) were more likely to use any form of tobacco compared to their counterparts.

CONCLUSIONS

Tobacco cessation interventions are warranted in this population focusing on alcohol users, men, those from lower income, rural residents and those belonging to a lower caste.

Social Determinants of Health and Tobacco Use in Five Low and Middle-Income Countries - Results from the Global Adult Tobacco Survey (GATS), 2011 - 2012

BACKGROUND

Tobacco consumption continues to be the leading cause of preventable deaths globally. The objective of this study was to examine the associaton of selected socio-demographic variables with current tobacco use in five countries that participated in the Phase II Global Adult Tobacco Survey in 2011 - 2012.

MATERIALS AND METHODS

We analysed internationally comparable representative household survey data from 33,482 respondents aged ≥ 15 years in Indonesia, Malaysia, Romania, Argentina and Nigeria for determinants of tobacco use within each country. Socio-demographic variables analysed included gender, age, residency, education, wealth index and awareness of smoking health consequences. Current tobacco use was defined as smoking or use of smokeless tobacco daily or occasionally.

RESULTS

The overall prevalence of tobacco use varied from 5.5% in Nigeria to 35.7% in Indonesia and was significantly higher among males than females in all five countries. Odds ratios for current tobacco use were significantly higher among males for all countries [with the greatest odds among Indonesian men (OR=67.4, 95% CI: 51.2-88.7)] and among urban dwellers in Romania. The odds of current tobacco use decreased as age increased for all countries except Nigeria where. The reverse was true for Argentina and Nigeria. Significant trends for decreasing tobacco use with increasing educational levels and wealth index were seen in Indonesia, Malaysia and Romania. Significant negative associations between current tobacco use and awareness of adverse health consequences of smoking were found in all countries except Argentina.

CONCLUSIONS

Males and the socially and economically disadvantaged populations are at the greatest risk of tobacco use. Tobacco control interventions maybe tailored to this segment of population and incorporate educational interventions to increase knowledge of adverse health consequences of smoking.

Work-Associated Stress and Nicotine Dependence among Law Enforcement Personnel in Mangalore, India

PURPOSE

To investigate the work associated stress and nicotine dependence among law enforcement personnel in Mangalore, India.

MATERIALS AND METHODS

A cross-sectional questionnaire survey was conducted among law enforcement personnel in Mangalore, India. Demographic details, stress factors experienced at work and nicotine dependency were the variables studied. The extent of stress factors experienced at work was assessed using the Effort-Reward Imbalance scale (ERI). Nicotine dependence was measured using the Fagerstrom Test for Nicotine Dependence (FTND) and the Fagerstrom Test for Nicotine Dependence-Smokeless Tobacco (FTND-ST). Logistic regression was used for the statistical analysis.

RESULTS

Three hundred and four law enforcement personnel participated in the study, among whom 68 had the presence of one or more habits like tobacco smoking, tobacco chewing and alcohol use. The mean effort score was 15.8±4.10 and the mean reward and mean overcommitment scores were 36.4±7.09 and 17.8±5.32 respectively. Effort/Reward ratio for the total participants was 1.0073 and for those with nicotine habit was 1.0850. Results of our study demonstrated no significant association between domains of ERI scale and presence of habits but work associated stress was associated with the presence of one or more habits. Compared to constables, head constables had 1.12 times higher risk of having a nicotine habit.

CONCLUSIONS

Our study implies job designation is associated with nicotine habits. However, there was no association between work associated stress and nicotine dependence among law enforcement personnel in Mangalore.

Level of Awareness of Various Aspects of Lung Cancer Among College Teachers in India: Impact of Cancer Awareness Programmes in Prevention and Early Detection

Lung cancer is one of the most common causes of cancer mortality among men in India and incidence is increasing, but actually, they are largely preventable diseases. In India, advanced stage at the time of presentation is responsible for high mortality and morbidity and early detection is the only way to reduce it. The purpose of this study is to know the level of awareness of various aspects of lung cancer among college teachers and impact of awareness programmes in its prevention and early detection. This assessment was part of Pink Chain Campaign-a campaign on cancer awareness. During the cancer awareness events in 2011-2013 at various women colleges in different parts in India, pre-test related to lung cancer was followed by awareness programme. Post-test using the same questionnaire was conducted at the end of interactive session, at 6 months and 1 year. A total of 872 out of 985 teachers participated in the study (overall response rate was 88.5 %). Mean age of the study population was 41.6 years (range 26-59 years). There was a significant increase in the level of knowledge regarding lung cancer at 6 months, and this was sustained at 1 year. Among teachers who were just asked yes or no question, 117 teachers (13.4 %) were smokers and 241 teachers (27.6 %) were alcoholics. Magazines and newspapers were sources for knowledge in 50-60 % of teachers, whereas approximately 30 % of teachers were educated by TV and Internet regarding various aspects of lung cancer. Post awareness at 6 months and 1 year, Pink Chain Campaign was the major source of knowledge related to lung cancer in more than 90 % of teachers by continuous and timely update on subject. Post awareness at 6 months and 1 year, there was a significant change in alcohol and smoking habits. Major reasons for not going for check-up were ignorance (83.1 %), fear (30.1 %) and lethargic attitude (29.3 %) initially, but over time, lack of time, lethargic attitude and hesitation became important factors after knowing various aspects of lung cancer. Knowledge of lung cancer was very low among teachers. Overall awareness of risk factors, sign and symptoms, screening modalities of lung cancer has improved in a year along with practices related to smoking and alcohol, but there was not much improvement in people undergoing regular check-ups. To inculcate safe practices in the lifestyle of people, awareness programmes such as the Pink Chain Campaign should be conducted more widely and frequently.

Current tobacco use and its associated factors among adults in a country with comprehensive ban on tobacco: findings from the nationally representative STEPS survey, Bhutan, 2014

BACKGROUND

Despite a comprehensive ban on cultivation, manufacture, distribution, and sale of tobacco products since 2004, two nationwide surveys conducted in 2012 and 2013 reported high tobacco use in Bhutan. National Health Survey 2012 reported that 4 % of the population aged 15-75 years used smoked tobacco and about 48 % used smokeless tobacco. Similarly, Global Youth Tobacco Survey (GYTS) of Bhutan reported tobacco use prevalence of 30.3 % in 2013. However, factors associated with this high tobacco use were not systematically studied. Hence, we assessed the prevalence of tobacco use and its associated sociodemographic, behavioral, and environmental factors.

METHODS

This cross-sectional analytical study used secondary data collected in a nationally representative Non-communicable Disease Risk Factors Surveillance STEPS Survey 2014 conducted among Bhutanese adults (18-69 years). The survey included a total of 2820 adults; selected using multistage stratified cluster sampling. Weighted analysis was done to calculate the prevalence of tobacco use. Unadjusted and adjusted prevalence ratios were calculated using log binomial regression.

RESULTS

The prevalence of current overall tobacco use was 24.8 % (95 % CI: 21.4-28.3) and that of smoked, smokeless, and dual forms (smoked and smokeless forms) were 7.4 % (95 % CI: 5.8-9.0), 19.7 % (95 % CI: 16.5-22.9), and 2.3 % (95 % CI: 1.8-2.9), respectively. Significantly higher prevalence of tobacco use in all forms was found among males, younger age groups, and alcohol users. The prevalence of smoked form was higher in urban areas compared to rural areas (11 % vs 6 %; aPR 1.8, 95 % CI: 1.5-2.0). Among individuals who reported having a non-communicable disease, the prevalence of smoked tobacco use was significantly lower than those who did not have disease (3.5 % vs. 8.3 %; aPR 0.5, 95 % CI: 0.3-0.9). Exposure to health warnings was protective for current tobacco use and smokeless tobacco use, while exposure to tobacco warnings through the media was helpful among smokers and overall tobacco users.

CONCLUSIONS

Despite a comprehensive ban on tobacco, tobacco use was high in Bhutan, especially the smokeless form. Males, younger age groups, and alcohol users should be targeted with behavioral interventions along the stricter implementation of tobacco control measures.

Trends of Smokeless Tobacco use among Adults (Aged 15-49 Years) in Bangladesh, India and Nepal

BACKGROUND

Smokeless tobacco (SLT) has long been realized as an important component of the fight for global tobacco control. It still remains a major problem in countries like India, Bangladesh and Nepal. The objective of this study was to estimate the trends of SLT use in three countries of the SEARO WHO office.

MATERIALS AND METHODS

We used data from national surveys in three countries (Bangladesh, India and Nepal) to estimate trends in prevalence of current SLT use. All available nationally representative data sources were used. Estimates were weighted, age standardized and given along with 95% confidence intervals. Significance of linear trend in prevalence over time was tested using the Cochrane-Armitage test for trend. A p value of less than 0.05 was considered statistically significant.

RESULTS

We identified three surveys for Bangladesh, three for India and four for Nepal that met the selection criteria (such as Demographic and Health Surveys, WHO-STEPwise approach to Surveillance and Global Adult Tobacco Surveys). A significantly increasing trend was noticed in the prevalence of current SLT use among Bangladeshi men (20.2% to 23%, p=0.03). In India, a similar significantly increasing trend was seen among men (27.1% to 33.4%, p<0.001) and women (10.1% to 15.7%, p<0.001). In Nepal, there was a no significant trend among both men (39.1% to 31.6%, p=0.11) and women (5.6% to 4.7%, p=0.49).

CONCLUSIONS

In the study countries SLT use has remained at alarmingly high levels. Usage trends do not show any signs of decline in spite of control efforts. Tobacco control measures should focus more on controlling SLT use.

The prevalence and risk factors for age-related macular degeneration in rural-urban India, Sankara Nethralaya Rural-Urban Age-related Macular degeneration study, Report No. 1

PurposeTo report the age- and gender-adjusted prevalence rates of early and late age-related maculopathy (ARM) and associated risk factors in rural and urban Indian population.MethodsA population-based cross-sectional study was carried out in South India between 2009 and 2011. Of the 6617 subjects ≥60 years enumerated ones, 5495 (83.04%) participated in the eye examination. A detailed history including data on demographic, socioeconomic, and ocular history was obtained. Participants underwent detailed ophthalmic evaluation including 30° 3-field photograph as per Age-Related Eye Disease Study protocol. The ARM was graded according to the International ARM Epidemiological Study Group.ResultsAge- and gender-adjusted prevalence of early ARM was 20.91% (20.86-20.94) in the rural population and 16.37% (16.32-16.42) in the urban population. Similarly, the prevalence of late ARM was 2.26% (2.24-2.29) and 2.32% (2.29-2.34) in the rural and urban population, respectively. In both rural and urban populations, risk factors that were related to both early and late ARM were age, per year increase (OR, range 1.00-1.08); middle socioeconomic status (OR, range 1.05-1.83); and smokeless tobacco (OR, range 1.11-2.21). Protective factor in both was the presence of diabetes mellitus in all ARM (OR, range 0.34-0.83). Risk factors, only in the rural arm, were female gender (OR, range 1.06-1.64), past smoker (OR, 1.14), and serum low-density lipoprotein cholesterol level (OR, 1.03).ConclusionsThe study reports smokessless tobacco as a risk factor for both early and late ARM and identified a higher prevalence of early ARM in the rural population compared with urban population.

Smokeless tobacco use in Urban Indian women: Prevalence and predictors

Context:

India is the second largest consumer of tobacco. Tobacco consumption in nonsmoking forms is culturally accepted even among women.

Aims:

This study aimed at understanding the patterns and predictors of smokeless tobacco (SLT) use among the urban low-socioeconomic women in Mumbai, India.

Materials and Methods:

This is a cross-sectional community-based survey of tobacco usage among women residing in seven low-socioeconomic communities in suburbs of Mumbai, India. Staff for the study was recruited, trained, clusters selected, accurately mapped, households identified, meetings held with community leaders, and household surveys conducted. Women using tobacco were invited to participate in the detailed survey and interviewed to document the various sociodemographic factors and in depth information on tobacco use. The data were computerized and analyzed.

Results:

About 22.30% of the total female population consumed tobacco, mainly in the smokeless forms, with only 0.50% of the tobacco users using smoked tobacco. Masheri was the most common form of tobacco used, followed by chewing tobacco. The median frequency of use of different tobacco products varied from 2 to 4 per day. The mean age at initiation of tobacco was 26.23 years. According to the results of univariate and multivariate logistic regression analysis, illiterate women, with advancing age, belonging to Hindu, Muslim, or Buddhist communities, who were either manual laborers or housewives, divorced or separated, and speaking Marathi were at higher risk of being tobacco user.

Conclusion:

Patterns and predictors of SLT use among women have been identified in the present study. This will guide in planning prevention and control strategies.

Tobacco chewing and adult mortality: a case-control analysis of 22,000 cases and 429,000 controls, never smoking tobacco and never drinking alcohol, in South India

BACKGROUND

Tobacco is consumed in both smoking and smokeless forms in India. About 35-40% of tobacco consumption in India is in the latter. The study objective was to describe the association between chewing tobacco and adult mortality.

MATERIALS AND METHODS

A case-control study was conducted in urban (Chennai city) and rural (Villupuram district) areas in Tamil Nadu state in South India. Interviewed in 1998-2000 about 80,000 families (48,000 urban and 32,000 rural) with members who had died during 1995-1998. These were the cases and their probable underlying cause of death was arrived at by verbal autopsy. Controls were 600,000 (500,000 urban, 100,000 rural) individuals from a survey conducted during 1998-2001 in the same two study areas from where cases were included.

RESULTS

Mortality analyses were restricted to non-smoking non-drinkers aged 35-69. The age, sex, education and study area adjusted mortality odds ratio was 30% higher (RR:1.3, 95%CI:1.2-1.4) in ever tobacco chewers compared to never chewers and was significant for deaths from respiratory diseases combined (RR:1.5, 95%CI:1.4-1.7), respiratory tuberculosis (RR:1.7, 95%CI:1.5-1.9), cancers all sites combined (RR:1.5, 95%CI:1.4-1.7) and stroke (RR:1.4, 95%CI:1.2-1.6). Of the cancers, the adjusted mortality odds ratio was significant for upper aero-digestive, stomach and cervical cancers. Chewing tobacco caused 7.1% of deaths from all medical causes.

CONCLUSIONS

The present study is the first large study in India analysing non-smoking non-drinkers. Statistically significant excess risks were found among ever tobacco chewers for respiratory diseases combined, respiratory tuberculosis, stroke and cancer (all sites combined) compared to never tobacco chewers.

Predictors of Tobacco Use among Youth in India: GATS 2009-2010 Survey

BACKGROUND

Tobacco use among youth in India is an increasingly rising burden. It is affected by various socio-demographic factors, which form predictors of use. Focus on these predictors can help policy makers in curbing the major morbidity and mortality due to tobacco among youth.

OBJECTIVE

To study the various socio- demographic variables associated with tobacco use among youth in India.

MATERIALS AND METHODS

The study was a secondary analysis of data from the Global Adult Tobacco Survey, India 2009-10, in the age group of 15-24 years. Predictors of smoking and smokeless tobacco were analysed using data on occupation, education, and other sociodemographic factors place of living. Epi Info used for conducting the analysis.

RESULTS

The total population interviewed in GATS India -2010 was 69,926. Of these the youth population between 15- 24. The total number of tobacco users (smokers and smokeless) was 2,969 (22.%). There were 11 (3.05%) dual users. Smokeless form of tobacco (15.1%) was used more than smoked form among youth. Males and urban youth preferred smoked form of tobacco over smokeless form. Smoking among youth had an inverse relation with increasing education level. Majority of smokeless form of tobacco users and dual users belonged to poor economic classes.

CONCLUSIONS

This productive age group is more susceptible to tobacco addiction, especially smokeless tobacco. Rural youth, students, female sex and poor socio-economic strata prefer smokeless whereas urban, male and lesser educated youth preferred smoked form of tobacco. Efforts should be directed towards discouraging tobacco use initiation among the young population in India.

Socioeconomic Gradients in Different Types of Tobacco Use in India: Evidence from Global Adult Tobacco Survey 2009-10

Socioeconomic differences in tobacco use have been reported, but there is a lack of evidence on how they vary according to types of tobacco use. This study explored socioeconomic differences associated with cigarette, bidi, smokeless tobacco (SLT), and dual use (smoking and smokeless tobacco use) in India and tested whether these differences vary by gender and residential area. Secondary analysis of Global Adult Tobacco Survey (GATS) 2009-10 (n = 69,296) was conducted. The primary outcomes were self-reported cigarette, bidi smoking, SLT, and dual use. The main explanatory variables were wealth, education, and occupation. Associations were assessed using multinomial logistic regressions. 69,030 adults participated in the study. Positive association was observed between wealth and prevalence of cigarette smoking while inverse associations were observed for bidi smoking, SLT, and dual use after adjustment for potential confounders. Inverse associations with education were observed for all four types after adjusting for confounders. Significant interactions were observed for gender and area in the association between cigarette, bidi, and smokeless tobacco use with wealth and education. The probability of cigarette smoking was higher for wealthier individuals while the probability of bidi smoking, smokeless tobacco use, and dual use was higher for those with lesser wealth and education.

Below the poverty line and non-communicable diseases in Kerala: The Epidemiology of Non-communicable Diseases in Rural Areas (ENDIRA) study

INTRODUCTION

India carries the greatest burden of global non-communicable diseases (NCDs). Poverty is strongly associated with NCDs but there are few prevalence studies which have measured poverty in India, particularly in rural settings.

METHODS

In Kerala, India, a population of 113,462 individuals was identified. The "Epidemiology of Non-communicable Diseases in Rural Areas" (ENDIRA) study was conducted via ASHAs (Accredited Social Health Activists). Standardised questionnaires were used in household interviews of individuals ≥18years during 2012 to gather sociodemographic, lifestyle and medical data for this population. The Government of Kerala definition of "the poverty line" was used. The association between below poverty line (BPL) status, NCDs and risk factors was analysed in multivariable regression models.

RESULTS

84,456 adults were included in the analyses (25.4% below the poverty line). The prevalence of NCDs was relatively common: myocardial infarction (MI) 1.4%, stroke 0.3%, respiratory diseases 5.0%, and cancer 1.1%. BPL status was not associated with age (p=0.96) or gender (p=0.26). Compared with those above the poverty line (APL), the BPL group was less likely to have diabetes, hypertension or dyslipidaemia (p<0.0001), and more likely to smoke (p<0.0001). Compared with APL, BPL was associated with stroke (OR 1.33, 1.04-1.69; p=0.02) and respiratory disease (OR 1.23, 1.15-1.32; p<0.0001) in multivariable analyses, but not MI or cancer.

CONCLUSIONS

In rural Kerala, BPL status was associated with stroke and respiratory diseases, but not with MI and cancer although it was associated with smoking status, compared with above poverty line status.

Tobacco use, beliefs and risk awareness in university students from 24 low, middle and emerging economy countries

The aim of this study was to determine the prevalence of tobacco use, beliefs and risk awareness and psychosocial correlates of tobacco use among university students in 24 low, middle and emerging economy countries. Using anonymous questionnaires, data were collected from 16953 undergraduate university students (mean age 20.9, SD=2.9) from 25 universities in 24 countries across Asia, Africa and the Americas. Results indicate that overall 13.3% of the university students were current tobacco users, 22.4% for men and 6.6% for women, ranging from 3.8% in Singapore to 32.5% in Cameroon. The risk awareness of the smoking lung cancer link was 83.6%, while the risk awareness of the smoking heart disease link was 46.5%. Multivariate logistic regression found that older age, male gender, having a wealthy family background, living in a low income country, residing off campus on their own, poor beliefs in the importance not to smoke, awareness of the smoking heart disease link, hit by a sexual partner, depressive symptoms, and substance use (binge drinking and illicit drug use) were associated with current tobacco use.

Analysis of motivating factors for smokeless tobacco use in two Indian states

BACKGROUND

This study was conducted to gauge how the demographic profile of smokeless tobacco (SLT) users from Gujarat and Andhra Pradesh, India, differs from that of smokers. It also addresses how factors associated with the initiation and continuation of smokeless tobacco vary by age, gender, and education.

MATERIALS AND METHODS

We analyzed 2011 cross-sectional survey data collected from 4,759 respondents (smokers/SLT users/ non-users) in both states. Chi-square analysis was used to make comparisons between the demographic profiles of smokers and SLT users. Multivariable logistic regression analysis was used to obtain the odds ratios (ORs) for initiation and continuation factors regressed on socio-demographic variables (age, gender, education).

RESULTS

Initiation-women were less likely than men to report "peer pressure", "fashion statement", and "stress/coping" as relevant factors for SLT use (OR: 0.45 CI: 0.30-0.70; OR: 0.42 CI: 0.24-0.74; OR: 2.47, CI: 1.47-4.15). Older age groups had lower odds of choosing "peer pressure" than the 15-24 year olds. Respondents with 11 or more years of education were more likely to report "stress/coping" than those with no education (OR: 2.82, CI: 1.06-7.48). Continuation-women were less likely than men to choose "relaxation", and "distance from family" as important continuation factors (OR: 0.50, CI:0.32-0.80; OR: 0.20, CI: 0.06-0.65). All age groups were less likely to choose "stimulation" as a factor than the youngest group.

CONCLUSIONS

Along with confirming and expanding upon previous literature, the findings of this study should encourage further SLT research in women and younger age groups (15-24 and 24-44). They also confirm the need for SLT prevention and cessation interventions in India in other community-based settings, besides schools.
