White paper on smokeless tobacco & women's health in India

Introduction

Smokeless tobacco (SLT) is defined as a product that contains tobacco, is not smoked or burned at the time of use, and commonly consumed orally or nasally. These products can be placed in the mouth, cheek or the lip and are sucked or chewed1. These are often used for gargling, and also as dentifrice2. The widespread use of SLT dates back to the early 16^th century due to its perceived properties of increasing salivation, reducing thirst and appetite, serving medicinal purposes and even reducing dependence on smoked tobacco3. Due to these properties, there has been a surge in its use across the nations, however, concrete evidence on its harm reduction has not been substantial45. Further, the carcinogenic nature of SLT products and the accompanying risk of being addicted to similar products warrant regulation and development of de-addiction strategies. The proliferation of various types of SLT products across regions, countries and tribes has ingrained practices of SLT use in cultural identities6. Thus, it remains challenging to develop data on health effects7 and regulate the product.

Tobacco use or abuse of any type in India has been largely viewed as a male-dominant behaviour. This paper highlights some of the key dimensions of SLT use among women in India with the aim of setting research priorities and policy agenda to achieve tobacco-free society.

Prevalence of SLT use

Despite the evidence of its harms and consequences, there is a high prevalence of SLT use in many populations across the globe; however, low- and middle-income countries (LMICs) share the largest burden8910. According to the Global Adult Tobacco Survey (GATS), some of the countries with a high prevalence of SLT use include India, Bangladesh, Egypt, Nigeria and the Philippines. However, among the global 248 million SLT users, 232 million belong to India and Bangladesh alone, wherein India alone carries more than 83 per cent of the global burden11. Evidence demonstrates that increasing use of SLT has not just been reported among adult males, but also among children, teenagers, women of reproductive age and immigrants of South Asia wherever they have migrated and settled6.

SLT use among women

In India, according to the latest GATS survey (2016-2017)12, 12.8 per cent women aged 15 yr and above were consuming any form of SLT. In absolute numbers, this corresponds to nearly 58.2 million women consuming any form of SLT in India. The SLT use among women was over 10 per cent in 16 States of India (Fig. 1). Although SLT use has declined from 18.4 per cent (GATS 2009-2010)13 to 12.8 per cent (GATS 2016-2017)12 among women, a relative increase in SLT use was evident in nine States of India. Nearly, 17 per cent of women in India initiated SLT use before the age of 15, much higher than men (11%)12. Among the various SLT product types, women in India consume betel quid with tobacco (4.5%), oral tobacco (4.3%) and khaini (4.2%), followed by gutka (2.7%) predominantly12.

SLT use among pregnant and lactating women

The use of SLT among pregnant women and exposure of foetuses to chemicals and hazards present in SLT products, is leading to many preventable morbidities and adverse outcomes14. The pooled prevalence of current SLT users among pregnant women was found to be lowest in Europe [0.1%, 95% confidence interval (CI): 0.0-0.3] and highest in Southeast Asia (2.6%, 0.0-7.6)15. Though a slight decline has been reported from 7.17 per cent to 3.95 per cent in the rates of SLT use in pregnant women in the decade since the third round of the National Family Health Survey (NFHS-3) (2005-2006)16 to NFHS-4 (2015-2016)17, the two nationally representative surveys (NFHS 2015-2016 and GATS 2016-2017)1217 have revealed that nearly 4.0 and 7.4 per cent women, respectively consuming any form of SLT were pregnant (Fig. 2 and Table). Moreover, the NFHS-4 (2015-2016)17 further suggests that nearly 5.0 per cent of lactating women in India consume SLT, which may directly harm neonatal health and nutrition. Both surveys also revealed substantial regional variations in SLT use among pregnant and lactating women. Among SLT product types, gutka and paan with tobacco were mostly consumed by both pregnant and lactating women (Table).

Determinants of SLT use

SLT use among women has been inversely associated with increasing levels of education, wealth and knowledge about the health effects18. It increases linearly with rise in age1920, more prevalent in rural women21 and also depends on taxation policies22. SLT use is found to be positively associated with its use by partner or peers2324. In a study conducted among married women at Mumbai, India, SLT use was found to be attributed for reducing stress, providing pleasure, associated companionship with peers at workplace and in the neighbourhood, increasing energy for workload and suppressing hunger when dietary requirements were not met25. Further, SLT use is often initiated at an early age as children and youth are often exposed to it when involved in purchase activities for their mothers and other older family members26. Often, individuals initiate use due to the lesser perceived harm on health from SLT use as compared to other methods of tobacco consumption such as smoking cigarettes and bidis27. Initiation of tobacco use in women often occurs during pregnancy28 as beliefs are often held by peers, family members and other individuals that tobacco can provide positive health effects and relief from common ailments and distress during pregnancy such as nausea, vomiting and constipation2930.

Adverse health effects of SLT use among women

Among women, SLT has been associated with the risk of oral31 and pharyngeal cancers32, cancer of the gums and buccal mucosa32, oesophageal cancer33, upper aero-digestive tract cancer (UADT)34, cervical cancer34, ischaemic heart disease (IHD)34 and osteoporosis35. A meta-analysis revealed higher risk for oral cancer among female SLT users with an odds ratio (OR) of 5.83 (95% CI: 2.93-11.58), as compared to 2.72 (1.73-4.27) for males and 3.35 (2.34-4.78) for combined sex36. In another study, the difference in mortality and cancer estimates among men and women for all causes (1.21 vs. 1.38), all cancers (1.42 vs. 1.62), UADT cancer (2.16 vs. 2.95) and IHD (0.97 vs. 1.13) showed higher risks for women as compared to men34.

SLT use and reproductive morbidities

The adverse health effects of SLT on pregnant women and neonatal health are numerous37. Compounds in SLT products such as nicotine can cross the placental barrier and act as neuroteratogens38 affecting the development of the brain, lungs and the central nervous system of the foetus39. Infertility, degenerative placental changes40, increased placental weight41, pregnancy complications42, pre-term delivery43, low-birth weight43, increased stillbirth risk44 and risk of cancers in the developing foetus39 are some of the adverse health effects of SLT use during pregnancy.

SLT use and nutrition

Use of SLT has been associated with low body mass index, and this association is found to be stronger among women (OR=2.19; 95% CI: 1.90-3.41) as compared to men (OR=1.83; 95% CI: 1.67-2.00)45. Tobacco use and poor nutrition may impair immunity46 and may lead to infections and poor reproductive outcomes. Because maternal micronutrient intake is an essential factor for optimum foetal growth47, the effect of toxins in SLT on depletion of antioxidant micronutrients may lead to poor nutritional outcomes in both the mother and the foetus45. Further, among pregnant women, mean haemoglobin levels have been observed to be lower in SLT users compared to those women who do not use SLT. This may lead to severe anaemia and affect the health of the foetus and may have long-lasting impacts on the health of the mother48.

Intention to quit, quitting attempts and cessation

In India, only about 5.8 per cent of adults have successfully quit SLT use12. The percentage of female users who attempted to quit SLT products (28.4%) was lower than the male users (35.2%). Moreover, when compared to men (33.3%), a lesser percentage of women (28.6%) were advised by healthcare providers to quit SLT use12. More than 50 per cent (54.4%) women SLT users were not interested in quitting, while the corresponding percentage was 45.1 per cent among men. Among all these women who attempted to quit SLT use in the year preceding the GATS survey, only 2.7 per cent sought pharmacotherapy and 8.4 per cent underwent counselling at local cessation centres or through telephone Quitline/helpline12. While only 4.3 per cent of the women opted for traditional methods to enable cessation, 71.6 per cent attempted cessation without any assistance12. This indicates an intrinsic issue with respect to access and willingness to enrol in cessation programmes or quitting practices as these centres often receive low number of female SLT users and participants. Low support for cessation, associated stigma and low access to cessation methods are some of the factors that may act as barriers to cessation among both men and women49. There is limited research on intention to quit and barriers to cessation among women that need to be understood to facilitate quitting and awareness.

Marketing, promotion and regulation

As most countries have smoke-free policies, tobacco companies attempt to market SLT products using means to circumvent these policies50. Aggressive selling strategies such as availability of SLT as single pouches have also increased its use in many LMICs, including India51. Various decision-making bodies have implemented policies aimed at reducing the sale and purchase of SLT products. In 2004, India ratified the WHO-Framework Convention on Tobacco Control (WHO-FCTC), which is a global instrument aimed at preventing and reducing tobacco use52. The legislative action for tobacco control in India started in 2003, when Cigarettes and Other Tobacco Products (prohibition of advertisement and regulation of trade and commerce, production, supply and distribution) Act (COTPA), 2003 prohibited any kind of tobacco advertising on all media platforms. COTPA also banned the sale of tobacco products to minors, and applied a ban on the sale of tobacco products within 100 yards of educational institutions and mandatory public health warnings and pictorial depiction of health hazards on packaging53.

In 2007-2008, the National Tobacco Control Programme (NTCP) was launched54 to generate awareness about the harmful effects of tobacco, reduce production and supply, ensure effective implementation of COTPA, enable cessation and facilitate implementation of tobacco control strategies as envisaged under the WHO-FCTC. Although initially focused on cigarette smoking, regulation of SLT products has also increased in recent years. Legal decisions aided by the advocacy measures by civil society and non-governmental organizations have allowed to regulate and control the use of tobacco5556575859. Despite all these measures to restrict the promotion of any form of tobacco products as well as dissemination of knowledge and awareness of adverse impact of tobacco use, nearly 45.3 per cent of women SLT users did not notice health-related warnings on SLT products, much higher than the male counterparts (21.5%)12.

Despite the presence of strong political will and favourable legal instruments, gender-based policies and women-centric actions are insignificant and the implementation of the NTCP by many States is not promising. Hence, educational and community-based health interventions are of paramount importance, especially for women and girls60.

Conclusion

According to The Oxford Medical Companion, tobacco is the only legalized product which, even when used in moderation and exactly as the manufacturer intended, causes harm to the consumer61. Tobacco products such as SLT that are often sold and produced locally, are being consumed by 248 million individuals globally with 206 million users (83.06%) from India11. Women, especially, pregnant and lactating, remain to be a neglected group in terms of understanding SLT use linkages and cessation strategies. Hence, it is essential to articulate the rights of women as human rights and engage in the development of gender-sensitive tobacco research62. This focus on women and girls is essential to achieve the national targets for tobacco control under the National Health Policy, 201763, and Sustainable Development Goals 3 of ensuring healthy lives and promote well-being for all64.
