Abstract
Sex disparities in cancer exist along the cancer spectrum, ranging from genomic predisposition and behavioral risk factors to access to screening, diagnostics, treatment, and survivorship care. A growing body of research is studying the biological underpinnings of these differences, from cancer risk to tumor biology to treatment response. It is well known, however, that the social determinants of health play a large role across the cancer disease continuum, which encompasses risk, prevention, diagnosis, treatment, survivorship, rehabilitation, and palliative care. Less literature focuses on the gendered disparities that are epidemiologic in nature, especially in Southeast Asia (SEA), a diverse region that is home to nearly 670 million people, where most are lower middle income countries, and where socioeconomic and cultural factors increase cancer risk for women. In this review, we highlight the social drivers of gendered disparities, namely the geographic, environmental, sociocultural, economic, and political forces that contribute to the increased mortality and poorer health outcomes in the region.

Ending Tobacco Use Through Interactive Tailored Messaging for Cambodian People With HIV (Project EndIT): Protocol for a Randomized Controlled Trial. JMIR Res Protoc 2023; 12:e48923. [PMID: 37384390 PMCID: PMC10365624 DOI: 10.2196/48923] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Accepted: 05/25/2023] [Indexed: 07/01/2023] Open
Abstract
BACKGROUND The prevalence of smoking remains high in many low- and middle-income countries (LMICs), including the Southeast Asian nation of Cambodia. Smoking is especially hazardous for people with HIV. In Cambodia, approximately 43%-65% of men with HIV and 3%-5% of women with HIV smoke cigarettes. Thus, there is a critical need for cost-effective smoking cessation interventions for Cambodian people with HIV. This paper describes the design, methods, and data analysis plans for a randomized controlled trial assessing the efficacy of a theory-based mobile health smoking cessation intervention in Cambodian people with HIV. OBJECTIVE This 2-group randomized controlled trial compares the efficacy of a mobile health-based automated messaging (AM) intervention versus standard care (SC) in facilitating smoking cessation among Cambodian people with HIV. METHODS Cambodian people with HIV who currently smoke and are receiving antiretroviral treatment (target, N=800) will be randomized to (1) SC or (2) the AM intervention. SC participants will receive brief advice to quit smoking, written self-help materials, nicotine patches, and will complete weekly app-delivered dietary assessments for 26 weeks. AM participants will receive all SC components (but will complete smoking-related weekly assessments instead of dietary assessments), in addition to a fully automated tailored messaging program driven by the weekly assessments to facilitate smoking cessation. In the Phase-Based Model of smoking cessation, the cessation process is partitioned into 4 phases: motivation, preparation (precessation), cessation (quit date to 2 weeks post quit), and maintenance (up to 6 months post quit). Our AM program targets processes within these phases, including increasing motivation to quit, enhancing self-efficacy, obtaining social support, skills to cope with nicotine withdrawal symptoms and stress, and skills to maintain abstinence. All participants will complete baseline and 3-, 6-, and 12-month in-person follow-up assessments. The primary outcome is biochemically confirmed abstinence at 12 months, with 3- and 6-month abstinence as secondary outcomes. Potential mediators and moderators underlying treatment effects will be explored, and cost-effectiveness will be assessed. RESULTS This study was approved by all relevant domestic and international institutional and ethical review boards. Participant recruitment commenced in January 2023. Data collection is expected to conclude by the end of 2025. CONCLUSIONS By demonstrating the greater efficacy and cost-effectiveness of AM relative to SC, this study has the potential to transform HIV care in Cambodia and prevent tobacco-related diseases. Furthermore, it may be adapted for use in other Cambodian populations and in other low- and middle-income countries. Ultimately, the AM approach to smoking cessation could greatly improve public health in the developing world and beyond.

Abstract
BACKGROUND The use of the Asian tobacco waterpipe (TWP) in the Lao People's Democratic Republic represents a potential communal source of infectious disease. This practice of smoking can lead to weakened defences of a smoker's respiratory epithelium, making the smoker vulnerable to respiratory diseases such as coronavirus disease 2019, tuberculosis and others. METHODS This study evaluated the water quality and hygiene factors among 43 smokers of five villages in rural Luang Namtha Province. Water samples were collected from participant's TWPs and assessed for the presence of Escherichia coli, coliforms and aerobic plate count (APC) bacteria using the 3M Petrifilm. RESULTS The microbial indicator testing results were 95% positive for the APC, 38% positive for coliforms and 17% positive for the E. coli indicator. The concentrations were highest for the APC, with an average of 106 colony forming units (cfu)/ml, followed by coliforms with <100 cfu/ml and lowest for E. coli with <10 cfu/ml. Most TWPs were infrequently cleaned, heavily used and contained a warm, brown-coloured water. CONCLUSIONS The warm, dark and moist internal water container may facilitate microbial survival and growth. The use of a TWP adds several unstudied modes of transmission to a complex and common biobehavioural and environmental pathogen exposure. Future TWP cessation activities should be tailored to consider risks of infectious disease transmission.

Prenatal Exposure to Gutkha, a Globally Relevant Smokeless Tobacco Product, Induces Hepatic Changes in Adult Mice. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17217895. [PMID: 33126512 PMCID: PMC7662769 DOI: 10.3390/ijerph17217895] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Revised: 10/07/2020] [Accepted: 10/15/2020] [Indexed: 12/16/2022]
Abstract
Maternal exposures during pregnancy affect the onset and progression of adult diseases in the offspring. A prior mouse study indicated that maternal tobacco smoke exposure affects hepatic fibrosis in adult offspring. Gutkha, a broadly used smokeless tobacco (ST) product, is widely used by pregnant woman in many countries. The objective of this murine study was to evaluate whether oral maternal exposure to gutkha during pregnancy alters non-alcoholic fatty liver disease (NAFLD) in adult offspring: risk factors for the progression of NAFLD to cirrhosis in adults remain elusive. Buccal cavity 'painting' of pregnant mice with gutkha began on gestational days (GD) 2-4 and continued until parturition. Beginning at 12 weeks of age, a subset of offspring were transitioned to a high-fat diet (HFD). Results demonstrated that prenatal exposure to gutkha followed by an HFD in adulthood significantly increased the histologic evidence of fatty liver disease only in adult male offspring. Changes in hepatic fibrosis-related cytokines (interleukin (IL)-1b and IL-6) and in hepatic collagen mRNA expression were observed when comparing adult male offspring exposed to gutkha in utero to those not exposed. These findings indicate that maternal use of gutkha during pregnancy affects NAFLD in adult offspring in a sex-dependent manner.

Abstract
Objective: Regional disparities in health services is a crucial problem in
Cambodia. Particularly, a number of NCD risk factors are more common among the rural poor.
Fortunately, 80% of NCDs are preventable and cost-effective interventions exist.
Therefore, health care needs assessments regarding NCDs in poor rural areas are vital. The
object of this pilot study was to identify health care needs regarding NCDs among
residents in poor rural areas in Cambodia. Materials and Methods: A medical health check-up and questionnaire survey
were conducted with 208 rural residents who participated in a free health check-up and
doctor consultation in Kaoh Peam Reang. Results: One hundred sixteen (55.8%) females were included in the total
sample size of 208 participants; the majority (52.9%) were between 35 and 65 years of age.
Twenty-five participants (12%) were current smokers, and 44 (21%) were current alcohol
drinkers. Eighty (38.5%) participants had hypertension and 44 participants (21.2%) had a
body mass index over 25. Alcohol drinking and smoking habits were more common among men.
The five most frequent medical complaints were headache (18.3%), lower back pain (14.4%),
foot and hand pain (13.9%), joint pain (10.1%), and difficulty breathing (10.1%). Conclusions: The medical need for doctor consultations regarding chronic
disease and chronic pain might be higher in poor rural areas in Cambodia.

Abstract
Cigarette smoking represents a major public health problem in Lao People's Democratic Republic (Lao PDR). This study aims to examine factors associated with cigarette smoking cessation attempts and intention to quit. Data were from the Lao National Adult Tobacco Survey that consisted of 7562 participants ≥15 years old. Multivariable logistic regression models were used to evaluate the associations, adjusted for sex, age groups, education level, income per day, and smoking frequency. Results show that past quit attempts were associated with visiting a healthcare provider in the past year (adjusted odds ratio [AOR]: 1.74, 95% confidence intervals [CI]: 1.28-2.35), home smoking bans (AOR: 5.52, 95% CI: 2.13-14.33), noticing media-based messages informing the dangers of smoking or encouraging quitting (AOR: 3.25, 95% CI: 2.28-4.63), noticing health warnings on cigarette packages in the past 30 days (AOR: 3.33, 95% CI: 2.21-5.03), and believing that smoking is seriously harmful to their health (AOR: 3.45, 95% CI: 1.24-9.57). The Lao PDR government should continue implementing tobacco control policies that demonstrated associations with cessation attempts or intention to quit, such as smoke-free environments and required health warnings on cigarette packages. Tobacco cessation treatment programs are pressingly needed in Lao PDR.

Abstract
Background: Areca nut (AN) and betel quid (BQ) chewing are ancient practices followed by an extensive proportion of the world's population. These practices are endemic in larger parts of South and Southeast Asia and selected Western Pacific countries. The prevalence of these habits varies across regions, age, gender, cultural practice, and socioeconomic status groups. Considerable variations exist between countries with respect to prevention/intervention programs, and policy guidelines of BQ usage. Objectives: (1) To provide an overview of the BQ chewing prevalence, practices, preventive interventions and policies in selected Asian and Western Pacific countries. (2) To explore the different terminologies associated with BQ use. Method: A narrative review of the current literature related to BQ, AN, and oral cancer was conducted by searching PUBMED, CINAHL, and GOOGLE databases. Results: The literature review revealed that the prevalence of BQ was found to be highest in Papua New Guinea, followed by Bangladesh, India, Pakistan, Myanmar and Sri Lanka. While, Cambodia, Malaysia, Indonesia and Taiwan had comparatively lower prevalence. Smokeless tobacco, BQ with tobacco, BQ without tobacco, AN were some of the terminologies used for BQ in various studies. Conclusions: The prevalence, and the interventional policies related to BQ and AN chewing habits varies widely among the selected countries. With the increasing awareness and association of BQ with oral cancer, there is a need to have better awareness, prevention and interventional strategies in place. We also found considerable variation in the use of terminologies associated with BQ.

Abstract
INTRODUCTION Tobacco use is a burden for Lao People's Democratic Republic (Lao PDR). No published report has examined determinants of various tobacco uses to inform appropriate policies and prevention strategies. This paper reports tobacco uses by sociodemographic characteristics using data from the most recent Lao National Adult Tobacco Survey (NATS) in 2015. METHODS The NATS included a nationally representative sample of 7562 people aged ≥15 years, recruited through a stratified 2-stage cluster sampling approach in 18 provinces. All analyses were weighted. Multivariable logistic regression models were used to evaluate unadjusted and adjusted associations between variables of interest. RESULTS The NATS results showed that 32.4% of Lao people aged ≥15 years were current tobacco users (men: 51.2%, women: 15.4%). Cigarette smoking accounted for approximately 95% of all tobacco use in men, while tobacco chewing accounted for 60% of tobacco use in women. Current tobacco use was strongly associated with older ages and lower education levels (p<0.001). There were interactions between sex, education level, and income associated with tobacco use; specifically, women were more likely to have a lower education level and lower income than men, and these women were more likely to use tobacco. CONCLUSIONS Tobacco use prevalence in Lao PDR was among the highest in the region. There were variations in types and prevalence of tobacco use across sociodemographic subpopulations. The Lao government should continue current national tobacco control efforts and implement additional proven strategies to reduce tobacco use.

Abstract
In Southeast Asia, household air pollution (HAP) from solid fuel use is the leading cause of disability-adjusted life years (DALYs), a risk which is compounded by exposure to other sources of indoor and outdoor air pollution including secondhand tobacco smoke (SHS). The purpose of this study was to measure the individual and combined prevalence of exposure to household and community sources of air pollution in a national sample of adults in Lao PDR. We analyzed data from the 2012 National Adult Tobacco Survey (NATSL) of Lao PDR-a multi-stage stratified cluster sample of 9706 subjects from 2822 households located in all 17 provinces. Our findings indicate a high prevalence of exposure to household air pollution from cooking fires (78%) and SHS exposure in the home (74.5%). More than a third (32.8%) reported exposure to both inside the home. Exposure to outdoor sources of smoke from cooking, trash, and crop fires was substantial (30.1% to 56.0%). The aggregation of exposures from multiple sources of household air pollution raises the need for initiatives that establish programmatic linkages in the health, environmental, and agricultural sectors to provide a comprehensive strategy to reduce risk factors for respiratory disease in Lao PDR and the region.

Abstract
In 2017, more than half of the global burden of incident tuberculosis (TB) came from the Western Pacific region. In Lao People's Democratic Republic (PDR), the high rates of tobacco use and use of polluting biomass fuels for cooking (e.g., wood, charcoal, crop waste, dung) represent significant risk factors for TB. The purpose of this study was to determine the association between self-reported (1) smoking and TB; and (2) exposure to air pollution (from both cooking fires and environmental tobacco smoke) and TB among adults in Lao PDR. We analyzed data from the 2012 National Adult Tobacco Survey (NATSL) of Lao PDR-a multi-stage stratified cluster sample of 9706 subjects from 2822 households located in all 17 provinces. Utilizing a nationally representative sample and inferential, multivariable methods, we observed a significant increase in odds of self-reported TB among those who smoked tobacco (OR = 1.73, 95% CI = (1.00 to 2.98)). Larger multivariable models identified independent contributions from exposure to tobacco pipes (OR = 21.51, 95% CI = (6.34 to 72.89)) and communal outdoor fires (OR = 2.27, 95% CI = (1.15 to 4.49)). An index measuring combined exposure to smoked tobacco, environmental tobacco smoke in enclosed workspace, indoor cooking fire, trash fires, and other outdoor communal fires also showed a positive association (OR per added exposure = 1.47, 95% CI = (1.14 to 1.89)). The findings of this study underscore the need for multi-sectoral collaboration between tobacco control, environmental health, TB prevention and treatment programs, national authorities, policy makers, civil groups, and the private sector to address the convergence of potential risk factors impacting respiratory health in Lao PDR.

Abstract
Objective We sought to assess how widowhood among older adults in India was associated with alcohol consumption, smoking, and use of chewing tobacco or other drugs. Method Data were collected in 2011 from 9,852 adults aged 60 and older from seven regionally diverse states in India. Regression analyses provided estimates of the relationship between widowhood and having smoked cigarettes, consumed alcohol, or used chewed tobacco or other drugs in the past month among men, adjusting for demographic and socioeconomic factors. We also estimated the relationship between widowhood and past-month substance use among women. Results Recently widowed men (within 0-4 years) were 1.76 times (95% confidence interval [CI] 1.01-3.09, p < .05) more likely to have consumed alcohol and 1.62 times (95% CI 1.01-2.59, p < .05) more likely to have used chewing tobacco or other drugs as compared with married men. Women widowed for any length of time were 1.37 times (95% CI 1.11-1.69, p < .01) more likely to have used chewing tobacco or other drugs. Discussion Interventions aimed at reducing use of chewing tobacco or other drugs among older adults in India should consider focusing on recently widowed men and women widowed for any amount of time.

BMC WOMENS HEALTH 2018; 18:154. [PMID: 30249233 PMCID: PMC6154788 DOI: 10.1186/s12905-018-0640-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/15/2016] [Accepted: 08/28/2018] [Indexed: 11/10/2022]
Abstract
BACKGROUND By 2030, the Sub-Saharan African region is projected to be the epicenter of the tobacco epidemic. While smoking prevalence is currently low among women (< 2%), the prevalence among men (7.7% overall and up to 27% depending on region) makes exposure to secondhand smoke a pressing concern for women and children. To prevent the uptake of smoking among women and address tobacco-related risks, including secondhand smoke exposure, a greater understanding of women's related perceptions is needed. The purpose of this study was to explore Ethiopian women's knowledge, attitudes, and beliefs related to tobacco use and secondhand smoke exposure, and the potential influence of contextual factors including; khat use, exposure to pro- and anti-tobacco messaging, and religious affiliation. METHODS A cross-sectional study using a systematic household sampling technique and an adapted interviewer-administered survey was conducted in Southern Ethiopia. The survey was administered to 353 women, 18-55 years of age, in Aleta Wondo town and surrounding districts between August-October 2014 (95.2% cooperation rate). RESULTS General awareness of harm associated with personal tobacco use and exposure to secondhand smoke was high (> 94%); however, specific knowledge of associated health-risks was limited. More than 96% perceived female tobacco use as socially unacceptable. At the same time, more than 70% were able to name potential benefits of using tobacco for both personal consumption and non-personal use. Respondents reported greater experimentation with khat versus tobacco and 73% reported that their religion significantly influenced their tobacco-related attitudes. Overall, there were higher reports of exposure to anti-tobacco (70%) versus pro-tobacco (49%) messaging, in the last 30 days. CONCLUSIONS The high level of awareness of health risks associated with tobacco use and SHS exposure and the high exposure to anti-tobacco messaging are community-level strengths that can proactively be built on to prevent the projected disease burden associated with tobacco. Findings have implications for the development of contextualized gender-specific tobacco control interventions, particularly in relation to the promotion of smoke-free homes.

Health Res Policy Syst 2017; 15:95. [PMID: 29126423 PMCID: PMC5681792 DOI: 10.1186/s12961-017-0260-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2016] [Accepted: 10/24/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Discussions within the health community routinely emphasise the importance of evidence in informing policy formulation and implementation. Much of the support for the evidence-based policy movement draws from concern that policy decisions are often based on inadequate engagement with high-quality evidence. In many such discussions, evidence is treated as differing only in quality, and assumed to improve decisions if it can only be used more. In contrast, political science scholars have described this as an overly simplistic view of the policy-making process, noting that research 'use' can mean a variety of things and relies on nuanced aspects of political systems. An approach more in recognition of how policy-making systems operate in practice can be to consider how institutions and ideas influence which pieces of evidence appear to be relevant for, and are used within, different policy processes. METHODS Drawing on in-depth interviews undertaken in 2015-2016 with key health sector stakeholders in Cambodia, we investigate the evidence perceived to be relevant to policy decisions for three contrasting health policy examples, namely tobacco control, HIV/AIDS and performance-based salary incentives. These cases allow us to examine the ways that policy-relevant evidence may differ given the framing of the issue and the broader institutional context in which evidence is considered. RESULTS The three health issues show few similarities in how pieces of evidence were used in various aspects of policy-making, despite all being discussed within a broad policy environment in which evidence-based policy-making is rhetorically championed. Instead, we find that evidence use can be better understood by mapping how these health policy issues differ in terms of the issue characteristics, and also in terms of the stakeholders structurally established as having a dominant influence for each issue. Both of these have important implications for evidence use. Contrasting concerns of key stakeholders meant that evidence related to differing issues could be understood in terms of how it was relevant to policy. The stakeholders involved, however, could further be seen to possess differing logics about how to go about achieving their various outcomes - logics that could further help explain the differences seen in evidence utilisation. CONCLUSION A comparative approach reiterates that evidence is not a uniform concept for which more is obviously better, but rather illustrates how different constructions and pieces of evidence become relevant in relation to the features of specific health policy decisions. An institutional approach that considers the structural position of stakeholders with differing core goals or objectives, as well as their logics related to evidence utilisation, can further help to understand some of the complexities of evidence use in health policy-making.

Abstract
British American Tobacco Cambodia (BATC) has dominated the country's tobacco market since its launch in 1996. Aggressive marketing in a weak regulatory environment and strategies to influence tobacco control policy have contributed to an emerging tobacco-related public health crisis. Analysis of internal tobacco industry documents, issues of BATC's in-house newsletter, civil society reports and media demonstrate that BATC officials have successfully sought to align the company with Cambodia's increasingly controversial political and business leadership that is centred around the Cambodian People's Party with the aim of gaining access to policy-makers and influencing the policy process. Connections to the political elite have resulted in official recognition of the company's ostensible contribution to Cambodia's economic and social development and, more significantly, provided BATC with opportunities to petition policy-makers and to dilute tobacco control regulation. Corporate promotion of its contribution to Cambodia's economic and social development is at odds with its determined efforts to thwart public health regulation and Cambodia's compliance with the Framework Convention on Tobacco Control.

Abstract
Palau, similar to other Pacific island countries, is currently highly burdened with non-communicable diseases (NCDs). The WHO STEPS was launched in 2011 to comprehensively survey indicators for NCDs in the country. This paper aims to describe the prevalence of key NCD risk factors assessed by the survey. The WHO instrument, including behavioral, physical and biochemical measurements, was adopted to the nationwide survey for all residents aged 25 to 64 years. A cluster-based sampling method was performed to obtain a national representative data. Valid data from 2,184 individuals were selected for the analyses, of which 75% were Palauans and 19% were Filipinos. Prevalence of current cigarette smoking was 25% in men and 10% in women. Betel nut chewing with tobacco was prevalent particularly among Palauans (58% in men, 69% in women) compared to the other ethnic groups. In terms of all types of tobacco use, 60% of men and 58% of women were current users. Overweight or obesity was very common among Palauans (84% in men, 86% in women) as well as Filipinos (52% in men, 40% in women). Hypertension was found in 55% of men and 49% of women, with the stage 2 hypertension being 21% and 19%, respectively. The prevalence of diabetic level hyperglycemia was more than 20%. Raised total cholesterol was detected in 16% of men and 20% of women. This survey revealed an alarmingly high prevalence of NCD risk factors, especially tobacco use, obesity, hypertension and raised blood glucose. The data would be useful baseline information to develop effective NCD strategies in Palau.

Abstract
Background Smoking is a strong risk factor for mortality in both the developed and the developing world. However, there is still limited research to examine the impact of smoking cessation and mortality in middle-income Southeast Asian populations. Methods We use longitudinal data from a large Thai cohort of adult Open University students residing nationwide, linked with official death records to assess the association of smoking status and mortality risks during a 7-year follow-up. The log-rank test was used to evaluate the statistical probability of differential survival according to baseline smoking status. Multivariate hazard ratios (HR) were reported for smoking status and all-cause and cause-specific mortality. Results From 2005 baseline to 2012, current smokers were more likely to die than cohort members who ceased smoking and never smokers (1.9 vs 1.3 vs 0.6 %, p < 0.05). The hazard of all-cause mortality increased with the daily amount of cigarette consumption among both current and former smokers. Cause of death analyses showed that current male smokers had a significantly increased risk of cardiovascular disease related mortality (HR 3.9 [95 % CI 1.8–8.1]). Former male smokers had a moderate increase in risk of dying from cardiovascular diseases compared to never smokers (HR 1.6 [95 % CI 0.7–3.4]). Current male smokers between 2005 and 2009 experienced highest subsequent mortality hazards during the period 2009–2012 compared to never smokers (HR 2.1 [95 % CI 1.4–3.4]). The higher risk of dying reduced if people quit smoking during the 2005–2009 follow-up period (HR 1.5 [95 % CI 0.7–3.3]). Risk for mortality fell even further among long-term quitters (HR 1.4 [95 % CI 0.9–2.2]). Conclusion Among a large nationwide cohort of Thai adults, current smokers were at a significantly and substantially higher risk of all-cause mortality, especially cardiovascular-related mortality. The higher risk of dying fell if people quit smoking and the risk for mortality was even lower among long-term quitters. Promotion of smoking cessation will contribute substantially to the reduction in avoidable mortality in Thailand.

Abstract
Refugees in the United States have high rates of chronic disease. Both long-term effects of the refugee experience and adjustment to the U.S. health environment may contribute. While there is significant research on health outcomes of newly resettled refugees and long-term mental health experiences of established refugees, there is currently little information about how the combined effects of the refugee experience and the U.S. health environment are related to health practices of refugees in the years and decades after resettlement. We examined cross-sectional survey data for Cambodian refugee and immigrant women 35 to 60 years old (n = 160) from an established refugee community in Lowell, Massachusetts, to examine the potential contributors to health behaviors and outcomes among refugees and immigrants postresettlement. In our representative sample, we found that smoking and betel nut use were very low (4% each). Fewer than 50% of respondents walked for at least 10 minutes on 2 or more days/week. Using World Health Organization standards for overweight/obese for Asians, 73% of respondents were overweight/obese and 56% were obese, indicating increased risk of chronic disease. Depression was also high in this sample (41%). In multivariate models, higher acculturation and age were associated with walking more often; lower education and higher acculturation were related to higher weight; and being divorced/separated or widowed and being older were related to higher risk of depression. The interrelated complex of characteristics, health behaviors, and health outcomes of refugees merits a multifaceted approach to health education and health promotion for long-term refugee health.

Factors associated with smoking in immigrants from non-western to western countries - what role does acculturation play? A systematic review. Tob Induc Dis 2015; 13:11. [PMID: 25908932 PMCID: PMC4407357 DOI: 10.1186/s12971-015-0036-9] [Citation(s) in RCA: 35] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2014] [Accepted: 03/28/2015] [Indexed: 12/21/2022] Open
Abstract
INTRODUCTION We aimed to identify factors associated with smoking among immigrants. In particular, we investigated the relationship between acculturation and smoking, taking into consideration the stage of the 'smoking epidemic' in the countries of origin and host countries of the immigrants. METHODS We searched PubMed for peer-reviewed quantitative studies. Studies were included if they focused on smoking among adult immigrants (foreign-born) from non-western countries now residing in the USA, Canada, Ireland, Germany, the Netherlands, Norway, the UK, and Australia. Studies were excluded if, among others, a distinction between immigrants and their (native-born) offspring was not made. RESULTS We retrieved 27 studies published between 1998 and 2013. 21 of the 27 studies focused on acculturation (using bidimensional multi-item scales particularly designed for the immigrant group under study and/or proxy measures such as language proficiency or length of stay in host country) and 16 of those found clear differences between men and women: whereas more acculturated women were more likely to smoke than less acculturated women, the contrary was observed among men. CONCLUSION Immigrants' countries of origin and host countries have reached different stages of the 'smoking epidemic' where, in addition, smoking among women lags behind that in men. Immigrants might 'move' between the stages as (I) the (non-western) countries of origin tend to be in the early phase, (II) the (western) host countries more in the advanced phase of the epidemic and (III) the arrival in the host countries initiates the acculturation process. This could explain the 'imported' high (men)/low (women) prevalence among less acculturated immigrants. The low (men)/high (women) prevalence among more acculturated immigrants indicates an adaptation towards the social norms of the host countries with ongoing acculturation.

Abstract
Background In South and Southeast Asian countries, tobacco is consumed in diverse forms, and smoking among women is very low. We aimed to provide national estimates of prevalence and social determinants of smoking and smokeless tobacco use among men and women separately. Methods Data from Demographic and Health Surveys completed in nine countries (India, Pakistan, Nepal, Bangladesh, Maldives, Philippines, Cambodia, Indonesia, and Timor Leste) were analyzed. Current smoking or smokeless tobacco use was assessed as response “yes” to one or more of three questions, such as “Do you currently smoke cigarettes?” Weighted country-level prevalence rates for socio-economic subgroups were calculated for smoking and smokeless tobacco use. Binary logistic regression analyses were done on STATA/IC (version 10) by ‘svy’ command. Results Prevalence and type of tobacco use among men and women varied across the countries and among socio-economic sub groups. Smoking prevalence was much lower in women than men in all countries. Smoking among men was very high in Indonesia, Maldives, and Bangladesh. Smokeless tobacco (mainly chewable) was used in diverse forms, particularly in India, among both men and women. Chewing tobacco was common in Nepal, Bangladesh, Maldives, and Cambodia. Both smoking and smokeless tobacco use were associated with higher age, lower education, and poverty, but their association with place of residence and marital status was not uniform between men and women across the countries. Conclusion Policymakers should consider type of tobacco consumption and their differentials among various population subgroups to implement country-specific tobacco control policies and target the vulnerable groups. Smokeless tobacco use should also be prioritized in tobacco control efforts.

Abstract
Smokeless tobacco use in the form of the betel quid is common in the Western Pacific Region, and yet few studies have determined the nicotine delivery of this habit. During a validation substudy, we randomly sampled 201 adults from a rural province of Cambodia and determined nonparametric (bootstrapped) confidence intervals (CIs) for salivary cotinine levels in tobacco users. We found that cotinine levels for daily betel quid use among women (95% CI = 218.6-350.0 ng/mL) were (1) similar to the levels for daily cigarette smoking in men (95% CI = 240.2-317.1 ng/mL) and (2) significantly higher than the levels for daily cigarette smoking in women (95% CI = 71.8-202.7 ng/mL). The 95% confidence range for these habits exceeded the threshold for addiction. Our findings from rural Cambodia indicate that the typical betel quid habit among women supports the same level of nicotine addiction as the typical cigarette habit in men.

Abstract
Smoking is still considered to be mainly a male problem. However, it is estimated that there are approximately 250 million women worldwide who smoke cigarettes and millions more women who use smokeless tobacco products. This article addresses the many facets of tobacco use among women. The aim of the paper is to increase recognition among clinicians and researchers of the specific characteristics of female tobacco use. Together with providing epidemiological data on the distribution of tobacco use among women and data from population-based analyses on sociocultural factors that influence it, the article presents tobacco use during pregnancy as a particularly important public health problem. Further, the article points out sex-related differences (ie, physiological, psychological, or behavioral) between male and female tobacco use. A special focus is on the important role of ovarian hormones. Adverse effects of tobacco use to women and their children as well as tobacco-related morbidities and comorbidities are presented, and women's greater susceptibility to tobacco constituents as compared to men is stressed. Awareness of these differences can contribute to improvement of the effectiveness of smoking cessation programs addressed both to the specific female population and to an individual smoking woman.

Abstract
Although the individual contributions of smoked tobacco and indoor air pollution have been identified, there are very few studies that have characterized and measured the effects of inhaled particles from a wide range of personal, household, and community practices common in rural Asia. The objective of our study was to examine the association between environmental inhaled exposures and lung function among rural males of Lao PDR. In a sample of 92 males from rural Lao PDR, study subjects completed a survey on household exposures, a physical exam, and the following measures of lung function: FEV1, FVC, and the ratio of FEV1/FVC. Our findings were as follows: a) > 80% of the subjects were exposed to indoor cooking fires (wood fuel), animal handling, dust and dirt; b) 57.6% of subjects were in the impaired range (FEV1/FVC < 0.7); and c) animal handling was negatively associated (p < 0.03) with FEV1 and FVC. Among males in rural Lao PDR, we found a high prevalence of chronic exposure to inhaled particles (animal handling, dust/dirt, smoke) and a high prevalence of impaired lung function. Findings from this pilot study indicate that associations between exposure to multiple sources of particulate matter common in rural areas and lung function need further investigation.

Abstract
In the Western Pacific Region, rural women use loose tobacco in betel quid chewing and pipe smoking. We examined the relation between maternal use of tobacco and infant mortality (IM) in a national sample of 24 296 birth outcomes in adult women (n = 6013) in Cambodia. We found that (1) age-adjusted odds of IM were higher for maternal use of any tobacco (odds ratio [OR] = 1.69; 95% confidence interval [CI] = 1.27-2.26); (2) age-adjusted odds of IM were higher for cigarette use (OR = 2.54; 95% CI = 1.54- 4.1), use of pipes (OR = 3.09; [95% CI = 1.86-5.11]), and betel quid chewing (OR = 1.55; 95% CI = 1.10-2.17); and (3) these associations remained after multivariable adjustment for environmental tobacco smoke, malnutrition, ethnicity, religion, marital status, education, income, occupation, and urban/rural dwelling. In addition to finding the established association with cigarettes, we also found that maternal use of smokeless tobacco and pipes was associated with higher rates of infant death in Cambodia.

Abstract
There remains a very high rate of smoked and smokeless tobacco use in the Western Pacific Region. The most recent findings from national adult tobacco surveys indicate that very few daily users of tobacco intend to quit tobacco use. In Cambodia, a nation that is predominantly Buddhist, faith-based tobacco control programs have been implemented where, under the fifth precept of Buddhism that proscribes addictive behaviors, monks were encouraged to quit tobacco and temples have been declared smoke-free. In the present study, we included items on a large national tobacco survey to examine the relation between beliefs (faith-based, other) about tobacco, health, and addiction among adults (18 years and older). In a stratified, multistage cluster sample (n=13,988) of all provinces of Cambodia, we found that (1) 88-93% believe that Buddhist monks should not use tobacco, buy tobacco, or be offered tobacco during a religious ceremony; (2) 86-93% believe that the Wat (temple) should be a smoke-free area; (3) 93-95% believe that tobacco is addictive in the same way as habits (opium, gambling, alcohol) listed under the fifth precept of Buddhism; and (4) those who do not use tobacco are significantly more likely to cite a Buddhist principle as part of their anti-tobacco beliefs. These data indicate that anti-tobacco sentiments are highly prevalent in the Buddhist belief system of Cambodian adults and are especially evident among non-users of tobacco. Our findings indicate that faith-based initiatives could be an effective part of anti-tobacco campaigns in Cambodia.

Abstract
To date, the sharing behaviors associated with the homemade tobacco waterpipe used in rural areas of the Western Pacific Region have not been studied. Evidence from studies of manufactured waterpipes raises the possibility of infectious disease transmission due to waterpipe sharing. The objective of our pilot study in rural Lao People’s Democratic Republic (PDR) was to identify and measure the prevalence of waterpipe sharing behaviors. We first conducted ethnographic studies to investigate waterpipe-smoking behaviors. These findings were then used to develop an interviewer-administered household survey that was used in a sampling of waterpipe smokers from three villages of the Luang Namtha province of Lao PDR (n = 43). Sampled waterpipe smokers were predominantly male (90.7%), older (mean age 49, SD 13.79), married (95.4%), farmers (78.6%), and had completed no primary education. Pipes were primarily made from bamboo (92.9%). Almost all (97.6%) smokers were willing to share their pipe with others. At the last time they smoked, smokers shared a pipe with at least one other person (1.2 ± 0.5 persons). During the past week, they had shared a pipe with five other persons (5.2 ± 3.8 persons). The high prevalence of sharing behaviors among waterpipe smokers in rural Southeast Asia raises the possibility that this behavior provides important and unmeasured social network pathways for the transmission of infectious agents.

Abstract
The validity of survey measures of smoked and smokeless tobacco use in the Western Pacific Region is often unknown. We conducted a validation study (n = 201) in a random sample of rural adults in Cambodia. A comparison with salivary cotinine indicated (1) that survey items and pictograms of current tobacco use had an 87% (95% confidence interval [CI] = 78%-93%) sensitivity, 94% specificity (95% CI = 87%-98%), and 93% (95% CI = 85%-97%) positive predictive value in detecting cotinine levels >10 ng/mL; (2) a positive correlation with number of cigarettes smoked (R = 0.34; P = .01); and (3) a positive correlation with the amount of tobacco chewed (R = 0.44; P = .02). The validity of the index for the amount of smokeless tobacco used was enhanced by adding to the index the data from pictograms that were utilized to help participants estimate the amount of loose tobacco used per session. These tobacco items and pictograms were found to have excellent reliability (κ = 0.80-1) over 2 to 3 weeks. Interviewer-administered survey items and pictograms can provide an accurate, quantitative measure of smoked and smokeless tobacco use in rural Cambodia.

Abstract
Current data indicate that under conditions of poverty, tobacco is consumed at the expense of basic needs. In a large national sample from Cambodia, we sought to determine whether tobacco consumption declines under extreme conditions of no income and malnutrition. Our major findings are as follows: (1) Among men, there was no significant difference in the number of cigarettes smoked for no income (425, 95% confidence interval [CI] = 395-456) versus >US$2 per day (442, 95% CI = 407-477); (2) among women, there was no significant difference in the amount of loose tobacco (ie, betel quid) consumed for no income (539 g, 95% CI = 441-637) versus >US$2 per day (558 g, 95% CI = 143-973); (3) for the contrast of no income + malnutrition versus >US$2 per day + no malnutrition in a linear model, there was no significant difference for men who smoked (462 vs 517 cigarettes/month, P = .82) or women who chewed (316 vs 404 g tobacco/month, P = .34), adjusting for confounders. Among the poorest and malnourished Cambodian adults, lack of resources did not appear to prevent them from obtaining smoked or smokeless tobacco.

Abstract
Although current trends indicate that the rate of cigarette smoking tends to be low among women in the Western Pacific Region (<10%), recent epidemiologic data from South Asia (India, Bangladesh) and Southeast Asia (Cambodia, Vietnam, Indonesia, Malaysia) identify that a large proportion of women of reproductive age and older chew tobacco—often as part of a betel quid mixture that includes other potentially harmful ingredients (eg, areca nut). Our findings from currently pregnant women identified during a nationwide survey of adult tobacco use in Cambodia indicate that 13.0% (95% confidence interval [CI] = 8% to 17%) were current users of smoked or smokeless (in the form of a betel quid) tobacco. Most pregnant women who used tobacco indicated that their habit was either initiated (29.1%; 95% CI = 16.3-46.3) or increased (33.7%; 95% CI = 18.3-53.5) during pregnancy. Pregnancy-related symptoms such as morning sickness were reported as the reason for more than half (54.9%; 95% CI = 34.8-73.4) of the currently pregnant users to have started a tobacco habit during their lifetime. Among those pregnant women who did not use tobacco, we found strong associations (odds ratios from 2 to 14) with beliefs about the harmful effects of tobacco on adult health, faith-based beliefs in addictive substances, and beliefs that influential members of the community, health professionals, and children should not use tobacco. Our findings indicate that tobacco cessation and prevention programs in Cambodia should specifically target pregnant and reproductive-age women.

Abstract
We analyzed data from a cohort study in rural Kerala, India, to study the incidence of current smoking and current smokeless tobacco use. At baseline, of 452 individuals aged 15 to 64 years, 385 were current nonsmokers and 402 were current nonusers of smokeless tobacco. Over a mean follow-up of 7.1 ± 0.2 years, 5.5% became current smokers and 9.0% became current smokeless tobacco users. Among men, 21.1% (95% confidence interval [CI] = 11.1-36.4) of younger individuals (15-24 years) became current smokers and 22.2% (CI = 10.6-40.8) of older individuals (55-64 years) became current smokeless tobacco users. No women smoked both at baseline and at follow-up, but 9.7% (CI = 3.4-24.9) of older women (55-64 years) became current smokeless tobacco users. These findings call for effective implementation of India's Cigarettes and Other Tobacco Products Act, 2003.

Abstract
BACKGROUND Cambodia has very high rates of tuberculosis and smoked tobacco use among adults. Efforts to control both tobacco use and tuberculosis in Cambodia need to be informed by nationally representative data. Our objective is to examine the relation between daily cigarette smoking and lifetime tuberculosis (TB) history in a national sample of adults in Cambodia. METHODS In 2011, a multi-stage, cluster sample of 15,615 adults (ages 15 years and older) from all regions of Cambodia were administered the Global Adult Tobacco Survey by interviewers from the National Institute of Statistics of Cambodia. RESULTS Our findings include: 1) among daily smokers, a significant positive relation between TB and number of cigarettes smoked per day (OR = 1.70 [95% CI 1.01, 2.87]) and pack-years of smoking (OR = 1.53 [95% CI 1.05, 2.25]) 2) a non-significant 58% increase in odds of ever having being diagnosed with TB among men who smoked manufactured cigarettes (OR = 1.58 [95% CI 0.97, 2.58]). CONCLUSION In Cambodia, manufactured cigarette smoking was associated with lifetime TB infection and the association was most evident among the heaviest smokers (> 1 pack per day, > 30 pack years).

Abstract
OBJECTIVE To assess how changes in socioeconomic and public health determinants may have contributed to the reduction in stunting prevalence seen among Cambodian children from 2000 to 2010. METHODS A nationally representative sample of 10 366 children younger than 5 years was obtained from pooled data of cross-sectional surveys conducted in Cambodia in 2000, 2005, and 2010. The authors used a multivariate hierarchical logistic model to examine the association between the prevalence of childhood stunting over time and certain determinants. They estimated those changes in the prevalence of stunting in 2010 that could have been achieved through further improvements in public health indicators. FINDINGS Child stunting was associated with the child's sex and age, type of birth, maternal height, maternal body mass index, previous birth intervals, number of household members, household wealth index score, access to improved sanitation facilities, presence of diarrhoea, parents' education, maternal tobacco use and mother's birth during the Khmer Rouge famine. The reduction in stunting prevalence during the past decade was attributable to improvements in household wealth, sanitation, parental education, birth spacing and maternal tobacco use. The prevalence of stunting would have been further reduced by scaling up the coverage of improved sanitation facilities, extending birth intervals, and eradicating maternal tobacco use. CONCLUSION Child stunting in Cambodia has decreased owing to socioeconomic development and public health improvements. Effective policy interventions for sanitation, birth spacing and maternal tobacco use, as well as equitable economic growth and education, are the keys to further improvement in child nutrition.

Abstract
Few studies have considered whether the habitual use of tobacco in Southeast Asia is part of an established pattern of addiction that includes regular alcohol use. As part of a national survey of adult tobacco use in Cambodia (n = 13 988), we found that men who smoked were 2 times more likely to have drank alcohol in the past week (odds ratio = 2.53, 95% confidence interval = 2.10-3.03). By age 18 to 25 years, 47% of male smokers drank alcohol, and this pattern of alcohol and tobacco use increased to >55% through the fifth decade. Women using smokeless tobacco with betel quid were more likely to be alcohol drinkers (odds ratio = 1.49, 95% confidence interval = 1.12-1.98). Past week's drinking declined by late middle age and was associated with lower education and being currently married; the behavior was lower in some ethnic groups (ie, Cham). Our findings indicate an important association between alcohol and tobacco use, and raise the possibility that reducing alcohol consumption can be an important component of tobacco control.

Abstract
Identifying determinants of intent to quit may aid the design of antitobacco programs and promote effective tobacco control policies. In a nationwide survey in Cambodia, two thirds of tobacco smokers and 45% of female smokeless tobacco users planned to stop in the future. Multivariate determinants of intent in 2279 male smokers were age <37 years, age at initiation ≥ 18 years, Cham versus Khmer ethnicity (odds ratio [OR] = 6.93; 95% confidence interval[CI] = 1.38-34.89), longer education, and professional occupation. In 1188 female smokeless tobacco users, age <25 years, age at initiation ≥ 18 years, and tuberculosis (OR = 3.26; 95% CI = 1.61-6.61) were associated with intent. In female smokers (n = 321), age 18 to 25 years at initiation was associated with intent. In male smokers and female smokeless tobacco users, perceived physical advantages of tobacco were inversely associated with intent. These findings underscore the importance of policies and interventions to delay initiation and promote cessation in young people and counteract perceived physical benefits.

Abstract
This study determined factors associated with quitting tobacco in Cambodia, a country with a high prevalence of men who smoke and women who use smokeless tobacco. As part of a nationwide survey, face-to-face interviews were conducted with 5145 current and 447 former tobacco users who had quit for ≥ 2 years. Determinants of quitting in multivariate analyses were age >48 years, age at initiation >25 years, ≥ 7 years of education, income ≥ 1 US dollar per day, professional (odds ratio [OR] = 2.52; 95% confidence interval [CI] = 1.27-5.01) or labor (OR = 1.98, 95% CI = 1.10-3.56) occupations, and heart disease (OR = 1.94; 95% CI = 1.10, 3.42). Smokeless tobacco users were 10-fold less likely to quit (OR = 0.10; 95% = CI 0.05-0.20) than smokers. In conclusion, tobacco cessation among Cambodians was lower than in nations with decades of comprehensive tobacco control policies. Tobacco cessation programs and policies should include all forms of tobacco and target young to middle-aged users before onset of disease and premature death.

Abstract
OBJECTIVES The habitual chewing of betel quid (areca nut, betel leaf, tobacco) is estimated to occur among 600 million persons in Asia and the Asia-Pacific Region. Emerging data from rural Asia indicate that the betel quid is part of traditional medicine practices that promote its use for a wide range of ailments, including infectious disease. In the present study, we examined the association between betel quid, traditional medicine, and infectious disease outcomes. METHODS For the purpose of a nationwide, interviewer-administered, cross-sectional survey of tobacco use (including betel quid), we conducted a stratified three-stage cluster sampling of 13 988 adults aged 18 years and older from all provinces of Cambodia. RESULTS We found an association between the intensity of betel quid use and HIV/AIDS (odds ratio (OR) 2.06, 95% CI 1.09-3.89), dengue fever (OR 2.40, 95% CI 1.55-2.72), tuberculosis (OR 1.50, 95% CI 0.96-2.36), and typhoid (OR 1.48, 95% CI 0.95-2.30). These associations were even stronger in women - the primary users of betel quid in Cambodia. Multivariable analyses that controlled for age, gender, income, education, urban versus rural dwelling, receiving care from traditional medicine practitioners, and cigarette smoking did not alter the betel quid-infectious disease association. CONCLUSIONS Our findings raise the possibility of a role of betel quid use in the transmission of infectious disease through pathways such as immunosuppression, oral route of entry for a pathogen (i.e., through injury to the oral mucosa), and contamination (i.e., fecal-oral) of the betel quid ingredients.

Abstract
OBJECTIVES We investigated the population burden of betel quid abuse and its related impact on oral premalignant disorders (OPDs) in South, Southeast, and East Asia. METHODS The Asian Betel-Quid Consortium conducted a multistage sampling of 8922 representative participants from Taiwan, Mainland China, Malaysia, Indonesia, Nepal, and Sri Lanka. Participants received an interviewer-administered survey and were examined for oral mucosal disorders. RESULTS The prevalence of betel quid abuse was 0.8% to 46.3% across 6 Asian populations. The abuse frequency was over 40.5% for current chewers, with the highest proportion in Nepalese and Southeast Asian chewers (76.9%-99.6%). Tobacco-added betel quid conferred higher abuse rates (74.4%-99.6%) among Malaysian, Indonesian, and Sri Lankan men than did tobacco-free betel quid (21.8%-89.1%). Gender, lower education level, younger age at chewing initiation, and clustering of familial betel quid use significantly contributed to higher abuse rates. Indonesian betel quid abusers showed the highest prevalence of OPDs and had a greater risk of OPDs than did nonabusers. CONCLUSIONS Betel quid abuse is high in regions of Asia where it is customarily practiced, and such abuse correlates highly with OPDs. By recognizing abuse-associated factors, health policies and preventive frameworks can be effectively constructed to combat these oral preneoplasms.

Abstract
Background Betel quid chewing is a common habit widely practiced in Southern Asian populations. However, variations are seen in the content of a betel quid across the different countries. Factors associated with commencement and cessation of this habit has been numerously studied. Unfortunately, data on Malaysian population is non-existent. This study aims to determine the factors associated with the inception and also cessation of betel quid chewing behaviour among Malaysian adults. Method This study is part of a nationwide survey on oral mucosal lesions carried out among 11,697 adults in all fourteen states in Malaysia. The questionnaire included sociodemographic information and details on betel quid chewing habit such as duration, type and frequency. The Kaplan-Meier estimates were calculated and plotted to compare the rates for the commencement and cessation of betel quid chewing behaviour. Cox proportional hazard regression models were used to calculate the hazard rate ratios for factors related to commencement or cessation of this habit. Results Of the total subjects, 8.2% were found to be betel quid chewers. This habit was more prevalent among females and, in terms of ethnicity, among the Indians and the Indigenous people of Sabah and Sarawak. Cessation of this habit was more commonly seen among males and the Chinese. Females were found to be significantly more likely to start (p < 0.0001) and less likely to stop the quid chewing habit. Females, those over 40 years old, Indians and a history of smoking was found to significantly increase the likelihood of developing a quid chewing habit (p < 0.0001). However, those who had stopped smoking were found to be significantly more likely to promote stopping the habit (p = 0.0064). Cessation was also more likely to be seen among those who chewed less than 5 quids per day (p < 0.05) and less likely to be seen among those who included areca nut and tobacco in their quid (p < 0.0001). Conclusion Factors that influence the development and cessation of this behaviour are gender, age, ethnicity, and also history of smoking habit while frequency and type of quid chewed are important factors for cessation of this habit.
