Defending Comprehensive Tobacco Control Policy Implementation in Nepal From Tobacco Industry Interference (2011-2018)

State of the literature discussing smoke-free policies globally: A narrative review

Despite the success of the Framework Convention on Tobacco Control (FCTC), most jurisdictions in the world do not have policies that create 100% smoke-free environments in indoor workplaces, indoor public places, public transport, or other public places. We conducted a narrative review of articles that discuss smoke-free policies and describe the state of the current literature. A search of peer-reviewed and gray literature, published between 1 January 2004 and 30 April 2022, was conducted using PubMed and EMBASE databases. We classified articles based on the location of the policy discussed (WHO region, World Bank income classification) and the environment that was being made smoke-free. Insights related to policy development and implementation, as well as compliance and enforcement, were also identified. The search identified 4469 unique citations; 134 articles met the criteria for inclusion and underwent data extraction by two independent coders. The sample included articles published in or about jurisdictions in each WHO region, in high- and low- and mediumincome countries, and articles that discussed policies regulating smoke-free indoor workplaces, indoor public places, public transport, outdoor/quasi-outdoor environments, and other (unspecified) public places. Some important insights from the literature related to smoke-free policy implementation included tobacco industry interference, the important role of civil society, and the need for effective communication, education, and leadership. Enforcement officials' awareness and training, stakeholders' attitudes and beliefs, and understanding social norms were identified as relevant determinants of effective smoke-free policies. There continue to be challenges for implementing smoke-free policies in jurisdictions throughout the globe, in high- and low- and middle-income countries. The literature includes insights to support 100% smoke-free policies in each environment that must be made smoke-free as per the FCTC.

A framework of NGO inside and outside strategies in the commercial determinants of health: findings from a narrative review

BACKGROUND

Public health scholarship has uncovered a wide range of strategies used by industry actors to promote their products and influence government regulation. Less is known about the strategies used by non-government organisations to attempt to influence commercial practices. This narrative review applies a political science typology to identify a suite of 'inside' and 'outside' strategies used by NGOs to attempt to influence the commercial determinants of health.

METHODS

We conducted a systematic search in Web of Science, ProQuest and Scopus. Articles were eligible for inclusion if they comprised an empirical study, explicitly sought to examine 'NGOs', were in English, and identified at least one NGO strategy aimed at commercial and/or government policy and practice.

RESULTS

One hundred forty-four studies met the inclusion criteria. Eight industry sectors were identified: extractive, tobacco, food, alcohol, pharmaceuticals, weapons, textiles and asbestos, and a small number of general studies. We identified 18 types of NGO strategies, categorised according to the target (i.e. commercial actor or government actor) and type of interaction with the target (i.e. inside or outside). Of these, five NGO 'inside' strategies targeted commercial actors directly: 1) participation in partnerships and multistakeholder initiatives; 2) private meetings and roundtables; 3) engaging with company AGMs and shareholders; 4) collaborations other than partnerships; and 5) litigation. 'Outside' strategies targeting commercial actors through the mobilisation of public opinion included 1) monitoring and reporting; 2) protests at industry sites; 3) boycotts; 4) directly engaging the public; and 5) creative use of alternative spaces. Four NGO 'inside' strategies directly targeting government actors included: 1) lobbying; 2) drafting legislation, policies and standards; 3) providing technical support and training; and 4) litigation. NGO 'outside' strategies targeting government included 1) protests and public campaigns; 2) monitoring and reporting; 3) forum shifting; and 4) proposing and initiating alternative solutions. We identified three types of NGO impact: substantive, procedural, and normative.

CONCLUSION

The analysis presents a matrix of NGO strategies used to target commercial and government actors across a range of industry sectors. This framework can be used to guide examination of which NGO strategies are effective and appropriate, and which conditions enable NGO influence.

Advocacy counterstrategies to tobacco industry interference in policymaking: a scoping review of peer-reviewed literature

BACKGROUND

There has been remarkable tobacco control progress in many places around the globe. Tobacco industry interference (TII) has been identified as the most significant barrier to further implementation of the World Health Organization Framework Convention on Tobacco Control (WHO FCTC). Civil society has been recognised as a key actor in countering TII. While TII has been extensively studied for several decades now, there is little research that focuses on counteractions to limit it and their effectiveness to do so. This scoping review seeks to map the peer-reviewed literature on civil society's activities of countering TII in policymaking to identify common counterstrategies and assess their effectiveness.

METHODS

Data sources: We searched Embase, IBSS, JSTOR, PubMed, Science Direct, Scopus and Web of Science using the following terms: ("Tobacco industry" OR "Tobacco compan*") AND. ("corporate political activity" OR "CPA" OR "lobbying" OR "interference") AND ("advoca*" OR "counter*" OR "activi*"), without time or language restrictions.

STUDY SELECTION

Our selection criteria included peer-reviewed studies that were written in English, German, or Spanish that drew on primary data and/or legal and policy documents and reported at least one specific example of civil society members or organisations countering tobacco industry action-based strategies.

DATA EXTRACTION

Advocates' counterstrategies were analysed inductively and countered industry strategies were analysed using the Policy Dystopia Model (PDM). Perceptions of effectiveness of countering attempts were analysed descriptively.

RESULTS

We found five common counterstrategies among 30 included papers covering five WHO regions; 1. Exposing industry conduct and false claims; 2. Accessing decision-makers; 3. Generating and using evidence; 4. Filing a complaint or taking legal action; 5. Mobilising coalition and potential supporters. These counterstrategies were used to work against a wide range of industry strategies, which are captured by five action-based strategies described in the PDM (Coalition Management, Information Management, Direct Access and Influence, Litigation, Reputation Management). While some studies reported the outcome of the countering activities, their impact remained largely underexplored.

CONCLUSION

The review shows that peer-reviewed literature documenting how civil society actors counter TII is scarce. It suggests that advocates employ a range of strategies to counter TII in its different forms and use them flexibly. More work is needed to better understand the effects of their actions. This could stimulate discussions about, and facilitate learning from, past experiences and help to further enhance advocates' capacity.

Corporate Political Activity: Taxonomies and Model of Corporate Influence on Public Policy

BACKGROUND

Non-communicable diseases (NCDs) kill 41 million people a year. The products and services of unhealthy commodity industries (UCIs) such as tobacco, alcohol, ultra-processed foods and beverages and gambling are responsible for much of this health burden. While effective public health policies are available to address this, UCIs have consistently sought to stop governments and global organisations adopting such policies through what is known as corporate political activity (CPA). We aimed to contribute to the study of CPA and development of effective counter-measures by formulating a model and evidence-informed taxonomies of UCI political activity.

METHODS

We used five complementary methods: critical interpretive synthesis of the conceptual CPA literature; brief interviews; expert co-author knowledge; stakeholder workshops; testing against the literature.

RESULTS

We found 11 original conceptualisations of CPA; four had been used by other researchers and reported in 24 additional review papers. Combining an interpretive synthesis of all these papers and feedback from users, we developed two taxonomies - one on framing strategies and one on action strategies. The former identified three frames (policy actors, problem, and solutions) and the latter six strategies (access and influence policy-making, use the law, manufacture support for industry, shape evidence to manufacture doubt, displace, and usurp public health, manage reputations to industry's advantage). We also offer an analysis of the strengths and weaknesses of UCI strategies and a model that situates industry CPA in the wider social, political, and economic context.

CONCLUSION

Our work confirms the similarity of CPA across UCIs and demonstrates its extensive and multi-faceted nature, the disproportionate power of corporations in policy spaces and the unacceptable conflicts of interest that characterise their engagement with policy-making. We suggest that industry CPA is recognised as a corruption of democracy, not an element of participatory democracy. Our taxonomies and model provide a starting point for developing effective solutions.

National Public Health Surveillance of Corporations in Key Unhealthy Commodity Industries - A Scoping Review and Framework Synthesis

BACKGROUND

Corporations in unhealthy commodity industries (UCIs) have growing influence on the health of national populations through practices that lead to increased consumption of unhealthy products. The use of government-led public health surveillance is best practice to better understand any emerging public health threat. However, there is minimal systematic evidence, generated and monitored by national governments, regarding the scope of UCI corporate practices and their impacts. This study aims to synthesise current frameworks that exist to identify and monitor UCI influence on health to highlight the range of practices deployed by corporations and inform future surveillance efforts in key UCIs.

METHODS

Seven biomedical, business and scientific databases were searched to identify literature focused on corporate practices that impact human health and frameworks for monitoring or assessment of the way UCIs impact health. Content analysis occurred in three phases, involving (1) the identification of framework documents in the literature and extraction of all corporate practices from the frameworks; (2) initial inductive grouping and synthesis followed by deductive synthesis using Lima and Galea's 'vehicles of power' as a heuristic; and (3) scoping for potential indicators linked to each corporate practice and development of an integrated framework.

RESULTS

Fourteen frameworks were identified with 37 individual corporate practices which were coded into five different themes according the Lima and Galea 'Corporate Practices and Health' framework. We proposed a summary framework to inform the public health surveillance of UCIs which outlines key actors, corporate practices and outcomes that should be considered. The proposed framework draws from the health policy triangle framework and synthesises key features of existing frameworks.

CONCLUSION

Systematic monitoring of the practices of UCIs is likely to enable governments to mitigate the negative health impacts of corporate practices. The proposed synthesised framework highlights the range of practices deployed by corporations for public health surveillance at a national government level. We argue there is significant precedent and great need for monitoring of these practices and the operationalisation of a UCI monitoring system should be the object of future research.

Strengthening policies and structures to combat illicit tobacco trade in the Philippines

The Philippines has been seeing an increase in illicit tobacco trade in recent years, undermining the impacts of legal measures such as tobacco products' taxation and regulation due to circumvention of established avenues and costing the government its revenue. Currently, the country has twelve policies related to the prevention of illicit tobacco trade with gaps identified in its lack of licensing systems for tobacco retailers and policies on law enforcement cooperation, which manifests in the country being fully compliant to only 5 of the 16 articles under the World Health Organization's Illicit Tobacco Trade Protocol. It is recommended that the country establish a national agency or framework specifically for illicit tobacco trade to address its gaps under Tracking and Tracing, Due Diligence, and Unlawful Conduct.

Tobacco Tax Increases: A Discourse Analysis of the French Print and Web News Media from 2000 to 2020

Lobbying led by the tobacco industry and tobacconists is a barrier to reducing smoking prevalence in France. Here, we analyze the discourse of the tobacco industry and other key actors (public health agencies, politicians, etc.) in the French general-audience news media from 2000 to 2020 around tobacco tax increases, which is one of the most effective tobacco control measures, especially amongst youth. We queried Europresse (a European news media and specialized press database) using the keywords "increase", "price or taxes", and "tobacco or cigarettes", and found 5409 topic-relevant articles, from which we extracted 8015 arguments for or against the measure. In total,64.3% were against the measure (mostly on grounds of "ufueling the black market"), 32.1% were for the measure (mostly claiming it is "effective at reducing smoking prevalence"), and 1.8% proposed alternative measures. Tobacconists, the primary source of media content on the topic, led a discourse that was strongly opposed to tax increases. Public health agencies, which attracted only half as much media attention, were strongly supportive of the measure. Analysis of discourses relayed in the French general-audience press revealed overwhelming opposition to tobacco tax increases, and this discourse was widely advanced by tobacconists. The results were congruent with international literature that had highlighted a similar set of arguments to those found in the French general press that were broadcasted by the tobacco industry and its allies (tobacconists in France) in an effort to block this evidence-based public health measure.

How do tobacco control policies work in low-income and middle-income countries? A realist synthesis

BACKGROUND

The burden of tobacco use is disproportionately high in low- and middle-income countries (LMICs). There is scarce theorisation on what works with respect to implementation of tobacco control policies in these settings. Given the complex nature of tobacco control policy implementation, diversity in outcomes of widely implemented policies and the defining role of the context, we conducted a realist synthesis to examine tobacco control policy implementation in LMICs.

METHODS

We conducted a systematic realist literature review to test an initial programme theory developed by the research team. We searched EBSCOHost and Web of Science, containing 19 databases. We included studies on implementation of government tobacco control policies in LMICs.

RESULTS

We included 47 studies that described several contextual factors, mechanisms and outcomes related to implementing tobacco control policies to varying depth. Our initial programme theory identified three overarching strategies: awareness, enforcement, and review systems involved in implementation. The refined programme theory identifies the plausible mechanisms through which these strategies could work. We found 30 mechanisms that could lead to varying implementation outcomes including normalisation of smoking in public places, stigmatisation of the smoker, citizen participation in the programme, fear of public opposition, feeling of kinship among violators and the rest of the community, empowerment of authorised officials, friction among different agencies, group identity among staff, shared learning, manipulation, intimidation and feeling left out in the policy-making process.

CONCLUSIONS

The synthesis provides an overview of the interplay of several contextual factors and mechanisms leading to varied implementation outcomes in LMICs. Decision-makers and other actors may benefit from examining the role of one or more of these mechanisms in their particular contexts to improve programme implementation. Further research into specific tobacco control policies and testing particular mechanisms will help deepen our understanding of tobacco control implementation in LMICs.

Progress in adopting bans on tobacco advertising, promotion, and sponsorship in the Americas: lessons from Uruguay and Argentina

Objective.

To assess progress in and barriers to implementing bans on tobacco advertising, promotion and sponsorship (TAPS) in Uruguay, which has a complete ban, and Argentina, with a partial ban.

Methods.

Legislation on TAPS bans in Uruguay and Argentina was reviewed and relevant published literature, news stories, civil society reports and tobacco industry reports retrieved to analyze progress in implementing TAPS bans.

Results.

In Uruguay, the complete TAPS ban, which includes standardized tobacco packaging, maintains high compliance and severely limits exposure of TAPS, despite a few problems with corporate social responsibility, social media, and transnational advertising. In Argentina, the partial TAPS ban has more problems with compliance and exposure to TAPS. The most important barriers to implementing TAPS bans in both countries are the tobacco companies. In Uruguay, tobacco companies do not comply in a few areas but the complete ban greatly minimizes this. In Argentina, however, tobacco companies can more easily exploit gaps in the partial TAPS ban, such as advertising at the points of sale, promoting contests, and using influencers on social media.

Conclusions.

The partial TAPS ban in Argentina illustrates the problems with enforcement and the tobacco industry’s ability to exploit loopholes and continue to market their products, especially to young people. A complete TAPS ban, including standardized tobacco packaging, as in Uruguay, is easier to implement and enforce and is effective in reducing exposure to tobacco advertising. Nevertheless, governments should prioritize implementing TAPS bans on social media, which remains a difficult sphere to monitor and allows tobacco companies to continue recruiting and targeting young people.

Securing Smokefree Laws Covering Casinos and Bars in Louisiana via Messaging, Continuous Campaigning and Health Coalitions

In this paper, we examine efforts by health organizations seeking comprehensive smokefree ordinances over Louisiana casinos and bars between 2010 and 2020 to determine best practices for increasing coverage. Bars and casinos remain less protected from secondhand smoke compared to other workplaces in the United States. Casino behavior is compared to the Policy Dystopia Model (PDM), a tobacco industry strategy framework. We performed a historical case study using snowball searches for news on the Access World News Database and the internet. We performed web searches using the names of key actors, organizations, and locations and interviewed nine participants. Starting in 2010, the Louisiana Campaign for Tobacco-Free Living ran ordinance campaigns supplemented by an ongoing statewide smokefree media initiative. Utilizing consistent strategies, including promoting performers as cultural emblems deserving protection, health organizations coalesced in New Orleans during 2014 and Baton Rouge in 2016 and 2017 to pursue ordinances. The coalitions secured ordinances in Louisiana's population and tourism centers despite business resistance. Organizations obtained 30 smokefree laws across Louisiana by 2021. Casinos used PDM strategies to resist ordinances, indicating the framework may predict strategies by non-tobacco entities resisting tobacco control. Louisiana shows that ongoing local campaigns, social justice themes and cultural messaging with coalitions in cities can secure smokefree laws covering casinos and bars and that local ordinance campaigns are a viable method for advancing smokefree protections over those venues in states where the state legislatures are resistant to action.

Compliance with the smoke-free public places legislation in Nepal: A cross-sectional study from Biratnagar Metropolitan City

Background

Smoke-free legislation banning tobacco smoking in public places was implemented across Nepal in 2014 with the ambition to reduce the impact of second-hand smoking. As part of a comprehensive policy package on tobacco control, the implementation of the legislation has seen a marked reduction in tobacco consumption. Yet there remains uncertainty about the level of compliance with smoke-free public places.

Objectives

This study assesses the compliance with smoke-free laws in public places and the factors associated with active smoking in public places in Biratnagar Metropolitan City, Nepal.

Methods

A cross-sectional study was conducted in the Biratnagar metropolitan city in Province 1 of Nepal from July to December 2019. A total of 725 public places within the metropolitan city were surveyed using a structured survey tool. Active smoking was the primary outcome of the study which was defined as smoking by any person during the data collection time at the designated public place.

Results

The overall compliance with smoke-free legislation was 56.4%. The highest compliance (75.0%) was observed in Government office buildings. The lowest compliance was observed in eateries, entertainment, and shopping venues (26.3%). There was a statistically significant association between active smoking and the presence of ‘no smoking’ notices appended at the entrance and the odds of active smoking in eateries, entertainment, hospitality, shopping venues, transportations and transits was higher compared to education and health care institutions. None of the ‘no smoking’ notices displayed fully adhered to the contents as prescribed by the law.

Conclusion

As more than half of the public places complied with the requirements of the legislation, there was satisfactory overall compliance with the smoke-free public places law in this study. The public venues (eateries, shopping venues and transportations) that are more frequently visited and have a high turnover of the public have lower compliance with the legislation. The content of the message in the ‘no smoking’ notices needs close attention to adhere to the legal requirements.

Two steps forward, one step back: the lead up to tobacco plain packaging policy in Turkey

The Turkish government first announced its intention to proceed with tobacco plain packaging legislation in 2011; however, it was 7 years before the legislation passed in December 2018. This study (conducted in 2018 before the legislation was passed) explored the policy context in Turkey between the first announcement that plain packaging legislation would be introduced and the passage of the legislation in 2018, and identified barriers and facilitators influencing its introduction. Publicly available documents relevant to plain packaging in Turkey were analysed. Interviews were conducted in 2018 with ten key informants including academics, bureaucrats in government ministries and leaders of non-government organizations (NGOs). Thematic analysis was undertaken, using a framework for systematically analysing how issues reach the policy agenda. The introduction of plain packaging legislation proved to be problematic, with many false starts and delays. Findings suggest these were mainly due to political barriers including changes in government, tobacco industry opposition and the national economic crisis. However, plain packaging legislation in Turkey managed to advance on the policy agenda, primarily through the collaborative advocacy efforts of NGOs, academics, and leadership from particular tobacco control advocates and politicians. Turkey's experience provides lessons for the wider uptake of tobacco plain packaging legislation, illustrating the critical importance of building effective coalitions between a range of stakeholders and political support within government while raising public awareness. Lay summary This research provides insights into the barriers and facilitators of decision making and action that shaped the process of introducing tobacco plain packaging legislation in Turkey. Major barriers that slowed Turkey's progress in enacting plain packaging included the financial and national economic crisis in 2018, changes in health ministers and opposition by the tobacco industry. A major facilitator of the policy process was the collaborative advocacy efforts of non-government organizations, academics, politicians and the leadership of certain tobacco control advocates. The insights from this case study may help other low- and middle-income countries to anticipate and successfully navigate the challenges involved in introducing tobacco plain packaging, an important policy measure for reducing the burden of tobacco-related disease in their populations, and its social and economic impacts. Building effective coalitions and fostering and supporting leadership are important strategies for the successful introduction of plain packaging legislation.

Evidence on article 5.3 of FCTC (tobacco industry interference in tobacco control activities) in India- a qualitative scoping study

BACKGROUND

The Tobacco Industry (henceforth TI) yearns to portray itself as being "socially responsible" and fights for the decision-making positions; that are it used to deter, delay or dilute tobacco control measures. There is little documented evidence of Tobacco Industry Interference (henceforth TII) from India, the scope of their interference and challenges faced by the experts for effective tobacco control. This research study seeks to cover this significant gap in the literature on the TI of India.

METHODS

A cross-sectional qualitative research design, based upon in-depth interviews (N = 26), was used to explore the key stakeholders' opinions regarding TII in India. The interviews used a set of questions to collect information about the participant's roles and responsibilities in tobacco control, the nature of TII faced by the participants, means of influence by TI, barriers and challenges to tobacco control efforts.

RESULTS

Most of the respondents were engaged in tobacco control, training, advocacy and awareness generation activities for 5-10 years or more. The respondents defined the TI and its scope as per their experience with the help of the power ranking methodology. Most of them perceived TI as 'manufacturers' while others consider them as 'advertisers', 'public relation companies', 'wholesalers', 'vendors', and 'Government firms with TI stocks. The research team identified six significant domains: influencing the policy and administrative decisions, Interference in the implementation of tobacco control laws and activities, false propaganda and hiding the truth, manipulating front action groups (FAG), rampant tobacco advertising and promotion activities and others under which TII activities were classified. Most respondents believed that TI players were interfering in the policy decisions, implementing the tobacco control laws and activities and manipulating the FAG. A detailed taxonomic classification of the TII strategies that emerged from our analysis was linked to article 5.3 of FCTC.

CONCLUSIONS

The study documented a significant level of TII in different domains, with stakeholders acting at various hierarchical levels. Thus providing insight into the tactics of the TI in order to enable stakeholders to anticipate and pre-empt the kinds of alliances the TI may attempt to build; stimulating academicians and researchers to undertake in-depth analysis into various strategies and therefore underscoring the need to ensuring transparency in official interaction with the TI and its representatives.

Food and beverage industry interference in science and policy: efforts to block soda tax implementation in Mexico and prevent international diffusion

Mexico is the largest soft drink market in the world, with high rates of obesity and type 2 diabetes. Due to strains on the nation’s productivity and healthcare spending, Mexican lawmakers implemented one of the world’s first public health taxes on sugar-sweetened beverages (SSBs) in 2014. Because Mexico’s tax was designed to reduce SSB consumption, it faced strong opposition from transnational food and beverage corporations. We analysed previously secret internal industry documents from major corporations in the University of California San Francisco’s Food Industry Documents Archive that shed light on the industry response to the Mexican soda tax. We also reviewed all available studies of the Mexican soda tax’s effectiveness, contrasting the results of industry-funded and non-industry-funded studies. We found that food and beverage industry trade organisations and front groups paid scientists to produce research suggesting that the tax failed to achieve health benefits while harming the economy. These results were disseminated before non-industry-funded studies could be finalized in peer review. Mexico still provided a real-world context for the first independent peer-reviewed studies documenting the effectiveness of soda taxation—studies that were ultimately promoted by the global health community. We conclude that the case of the Mexican soda tax shows that industry resistance can persist well after new policies have become law as vested interests seek to roll back legislation, and to stall or prevent policy diffusion. It also underscores the decisive role that conflict-of-interest-free, peer-reviewed research can play in implementing health policy innovations.

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.

Comparison of Liquefied Petroleum Gas Cookstoves and Wood Cooking Fires on PM2.5 Trends in Brick Workers' Homes in Nepal

Prior studies document a high prevalence of respiratory symptoms among brick workers in Nepal, which may be partially caused by non-occupational exposure to fine particulate matter (PM_2.5) from cooking. In this study, we compared PM_2.5 levels and 24 h trends in brick workers' homes that used wood or liquefied petroleum gas (LPG) cooking fuel. PM_2.5 filter-based and real-time nephelometer data were collected for approximately 24 h in homes and outdoors. PM_2.5 was significantly associated with fuel type and location (p < 0.0001). Pairwise comparisons found significant differences between gas, indoor (geometric mean (GM): 79.32 μg/m³), and wood, indoor (GM: 541.14 μg/m³; p = 0.0002), and between wood, indoor, and outdoor (GM: 48.38 μg/m³; p = 0.0006) but not between gas, indoor, and outdoor (p = 0.56). For wood fuel homes, exposure peaks coincided with mealtimes. For LPG fuel homes, indoor levels may be explained by infiltration of ambient air pollution. In both wood and LPG fuel homes, PM_2.5 levels exceeded the 24 h limit (25.0 µg/m³) proposed by the World Health Organization. Our findings suggest that increasing the adoption of LPG cookstoves and decreasing ambient air pollution in the Kathmandu valley will significantly lower daily PM_2.5 exposures of brick workers and their families.
