RESUMO
Betel quid (BQ) is the fourth most popular psychoactive substance in the world, and BQ use disorder (BUD) is prevalent in Asian countries. Although the mechanisms underlying BUD remain unclear, studies have reported influences from monoamine oxidase inhibitor. We enrolled 50 patients with BUD and assessed their BQ consumption habits, emotional conditions, and the clinical severity of addiction-assessed using the Diagnostic and Statistical Manual of Mental Disorders [Fifth Edition] (DSM-5) criteria, Substance Use Severity Rating Scale, and Yale-Brown Obsessive Compulsive Disorder Rating Scale for BQ. Patients were categorized into the severe group when showing six or more symptoms defined by DSM-5. A genome-wide association study was conducted for single nucleotide polymorphisms in BRCA1, COL9A1, NOTCH1, HSPA13, FAT1, and MAOA by using patients' blood samples. More severe BUD symptoms were associated with younger age of using BQ and poor oral hygiene and with severe craving for and more anxiety toward BQ use. The MAOA rs5953210 polymorphism was significantly associated with severe BUD (odds ratio, 6.43; 95% confidence interval, 5.12-7.74; p < 0.01) and might contribute to BQ-associated cancer risk. Further studies are required to investigate the addictive properties of BQ and the development of novel diagnostic tools and pharmacotherapeutic alternatives to BUD treatment.
RESUMO
INTRODUCTION: Habitual betel quid chewing, a tobacco product, is a leading cause of oral cancer in Asia-Pacific countries where this practice is most prevalent. However, it is not well understood whether betel quid chewing is also a cause of adverse cardiovascular outcomes. To address this gap, we conducted a systematic literature review of peer-reviewed published studies evaluating the association between habitual betel quid use on the risk of adverse cardiovascular outcomes. METHODS: We searched PubMed for studies assessing the correlation between betel quid chewing and cardiovascular health. We included studies if (i) they included human subjects; (ii) were peer-reviewed articles in indexed journals; and (iii) were in English. We extracted data from eligible studies and stratified them by geographical location, study designs and cardiovascular outcomes. Finally, we did a narrative synthesis of the data to identify adverse cardiovascular outcomes associated with chronic betel quid use. FINDINGS: We reviewed data from 19 studies that met the inclusion criteria. Habitual betel quid chewing was associated with hypertension, atherosclerosis, inflammation and ischaemic heart disease. In addition, betel quid use was a risk factor for arrhythmias. Interestingly, betel quid use was an independent risk factor for cardiovascular disease in women. Long-term betel quid consumption was associated with higher risks for all-cause mortality and increased overall cardiovascular risk. CONCLUSIONS: Habitual betel quid chewing is an important cardiovascular risk factor in populations where the practice is prevalent.

INTRODUCTION: The association between areca nut consumption and oral cancer has been a subject of increasing concern in global public health. GLOBAL PERSPECTIVE: Areca nut, often chewed in various forms such as betel quid, is deeply rooted in cultural practices across Asia and other parts of the world. Epidemiological studies consistently reveal a significant correlation between areca nut use and the incidence of oral cancer, emphasizing the need for targeted preventive measures. The complex interplay of areca nut's bioactive compounds, particularly arecoline, with cellular processes, contributes to the initiation and progression of oral carcinogenesis. Mechanistic insights into the genotoxic and cytotoxic effects of its components underscore the urgency for comprehensive public health interventions. PUBLIC HEALTH: Efforts to address this public health challenge involve multidisciplinary approaches, encompassing education, policy implementation, and behavioral interventions. Understanding the socio-cultural factors influencing areca nut consumption is pivotal for designing effective awareness campaigns and cessation programs. CONCLUSION: As oral cancer remains a significant global health burden, unraveling the nuanced relationship between areca nut and its role in oral carcinogenesis is crucial for advancing preventive strategies and mitigating the impact of this modifiable risk factor.
RESUMO
OBJECTIVES: To provide updated statistics of oral cancer incidence and mortality in Taiwan, and to describe recent developments for oral cancer control to reduce oral cancer incidence and mortality. METHODS: The Taiwan Cancer Registry Annual Report 2023, the Taiwan Cancer Registry Online Interactive Search System, and the 2023 Health Promotion Administration Annual Report are consulted and summarized. A literature search using PubMed was also conducted to identify Taiwan oral cancer control-related studies. RESULTS: Taiwan, with a long history of areca/betel quid chewing, has battled with oral cancer for decades. In 2021, the male lip and oral cavity cancer incidence is 29.77 (per 100,000 persons) and mortality is 11.25. Over these years, the male chewing prevalence was reduced to 6.2% in 2018. Taiwan has a sustained national oral cancer screening programme provided to high-risk groups biennially. CONCLUSIONS: Although the age-standardized incidence rates have been slowly decreasing since 2009, due to Taiwan's ageing population, the actual oral cancer burden is still stringent. The collaboration of multi-ministries and agencies on promoting areca nut and betel quid control, improving oral cancer awareness, and delivering cancer care remains essential to prevent oral cancer and reduce oral cancer deaths.
RESUMO
BACKGROUND: The Betel Nut Intervention Trial (BENIT; ClinicalTrials.gov - NCT02942745) is the first known randomized intervention trial specifically designed for areca nut chewers in the western Pacific region who want to quit. The current study is a separate, exploratory study that examined the experiences of the BENIT facilitators during its implementation in Guam and Saipan of the Northern Mariana Islands and the extent to which the BENIT protocol was adapted to meet the participants' and facilitators' needs. METHODS: All six BENIT program facilitators completed an online survey consisting of quantitative (Likert scale) and qualitative (open-ended) questions. Survey items were grouped as follows: facilitator demographics, prior training and preparation, BENIT experience, beliefs about the program's effectiveness, and beliefs about protocol adaptations. RESULTS: Most of the facilitators felt prepared to deliver the BENIT program after several weeks of moderately intensive training. Facilitators felt the BENIT program was generally effective and that the "trigger logs" and "self-monitoring logs" worked as intended. However, they also noted that more time and support would have been helpful to overcome some of the obstacles inherent to implementing a novel program. CONCLUSION: The current findings can be used to inform, modify, and tailor subsequent areca nut cessation programs in Micronesian communities and to improve future versions of BENIT.

Introduction: Betel quid (BQ) is globally the fourth most consumed psychoactive substance. It is consumed by an estimated 600 million people worldwide, accounting for nearly 8% of the world's population. There have been very few studies assessing chewers' motivation to quit. Objectives: In the current study, we sought to understand the relationship between several cessation-relevant variables and chewers' motivation to quit. Hypotheses: Based on analogous research on cigarette smoking, we hypothesized that the following cessation-relevant variables would be associated with motivation to quit: health risk perceptions, number of chews per day, cost, degree of BQ dependence, withdrawal symptoms, number of quit attempts, reasons for use, personal health improvement, and type of BQ chewed. Methods: A total of 351 adult BQ chewers from Guam participated in the survey and served as the sample for the analyses. Results: Majority of chewers want to quit and intend to quit. Chewers relatively high in motivation to quit evinced greater health risk perceptions of BQ chewing, greater perceived health benefits to quitting, and a greater number of past quit attempts, compared to those relatively low in motivation to quit. Conclusions: Understanding which factors are associated with chewers' motivation to quit can be helpful for designing BQ cessation programs. The results suggest that BQ cessation programs could be improved by an increased emphasis on information about the negative health effects of BQ chewing and relapse-prevention.

Oral submucous fibrosis (OSF) is a chronic, progressive condition affecting the oral mucosa associated with areca nut consumption. It leads to restricted tongue movement, loss of papillae, blanching and stiffening of the mucosa, difficulty in opening the mouth, and challenges in eating due to inflammation and fibrosis. This report presents a rare case of oropharyngeal stenosis secondary to OSF in a 43-year-old male with a history of chewing betel nut. A surgical procedure similar to Uvulopalatopharyngoplasty was performed to excise the submucous oropharyngeal stenosis and to reconstruct the uvula, palatoglossal arch, and palatopharyngeal arch. At 8 years postoperatively, the patient exhibited a normal mouth opening and oropharyngeal aperture.

BACKGROUND: Chewing betel nuts can increase the risk of periodontal disease severity and potentially become malignant in the oral cavity. OBJECTIVE: This study aimed to investigate the effect of the duration and frequency of betel quid chewing behaviour on periodontitis severity and the life quality of people in Tanini Village, Kupang Regency, Indonesia. METHODS: The type of this study was an analytic observational study with a cross-sectional design. We used a questionnaire to obtain sociodemographic data. Oral Health Survey Basic Methods were used to measure debris index, plaque index, bleeding on probing, loss of attachment, and pocket depth. Behaviour and quality of life were measured by questionnaire and WHOQOL-BREF method as well. RESULTS: The largest number of respondents were male. Duration of chewing had a significant relationship with the frequency of chewing and periodontal status. Periodontitis was higher compared to all categories. The lifestyle of the community greatly influenced their behaviour in betel nut chewing and also affected the severity of their periodontitis and OHIs significantly. CONCLUSION: The lifestyle of betel nut chewing of the people in Tanini Village, greatly influences their behaviour. Prolonged and excessive use of betel nut induced significant adverse effects on human health. The longer and more often chew betel or areca nut, the higher the incidence of periodontitis, which significantly affects the quality of life as there is a possibility of the development of carcinogenesis, particularly in the oral cavity.

A disintegrin and metalloproteinase domain-containing protein 10 (ADAM-10) involves in the tumour progression, but the impacts of single-nucleotide polymorphism (SNP) of ADAM-10 on oral squamous cell carcinoma (OSCC) remain unclear. The aim of this study was to investigate the influence of SNP of ADAM-10 on the clinical features of OSCC in male Taiwanese. Five loci of ADAM-10 SNPs including rs653765 (C/T), rs2305421 (A/G), rs514049 (A/C), rs383902 (T/C) and rs2054096 (A/T) were genotyped by TaqMan allelic discrimination in 1138 OSCC patients and 1199 non-OSCC individuals. The ADAM-10 SNP rs2305421 GG (AOR: 1.399, 95% CI: 1.045-1.874, p = 0.024) and G allele (AOR: 1.170, 95% CI: 1.012-1.351, p = 0.034) illustrated a significantly higher genotypic frequencies in the OSCC group compared to the distribution of the ADAM-10 SNP rs2305421 AA wild type. In the subgroup analysis, the ADAM-10 SNP rs383902 TC+CC was significantly correlated to tumour size larger than T2 in betel quid chewer (AOR: 1.375, 95% CI: 1.010-1.872, p = 0.043), while the ADAM-10 SNP rs653765 CT+TT was significantly associated with tumour size larger than T2 in cigarette smoker (AOR: 1.346, 95% CI: 1.023-1.772, p = 0.034). The results from The Cancer Genome Atlas revealed highest ADAM-10 mRNA level in T2 stage of current smokers with head and neck squamous cell carcinoma (HNSCC). In conclusions, the ADAM-10 SNP rs2305421 G allele is associated with the presence of OSCC, and the ADAM-10 SNP rs383902 TC+CC and ADAM-10 SNP rs653765 CT+TT correlates to large tumour size in specific conditions.

BACKGROUND: Betel quid (BQ) is the fourth most popular psychoactive agent worldwide. Neuroimaging studies have showed that substance-addicted individuals including alcohol, heroin, nicotine and other addictive substance exhibit altered activity patterns of the salience network (SN). However, no study has yet investigated the neural correlates of the resting-state SN and BQ dependence (BQD)-related physiopathological characteristics. METHODS: Thirty-two BQ-dependent (BQD) chewers and 32 healthy controls were recruited to participate in this study. Resting-state functional magnetic resonance imaging (fMRI) data were analysed by independent component analysis (ICA). RESULTS: BQD chewers exhibited decreased functional connectivity in bilateral insula, anterior cingulate cortex (ACC), medial superior frontal gyrus (MSFG) and inferior orbital frontal gyrus (IOFG) [false discovery rate (FDR) correction, p < 0.05]. In the BQD group, the decreased functional connectivity in left ACC correlated negatively with BQDS (BQD Scale) and the duration of BQ. CONCLUSIONS: We reported decreased functional connectivity in resting-state SN of BQD individuals. The decreased functional connectivity in left ACC correlated negatively with BQDS and the duration of BQ. Our findings provided evidence for the importance of the SN in the pathophysiology of BQD and indicated that the SN dysfunction might provide a potential mechanism in BQD development.

The temporal variability of the dynamic functional connectivity (dFC) has been suggested as a useful metric for studying abnormal cognitive function. This study aimed to explore the associations between the temporal properties of dFC and memory performance in betel quid dependence (BQD). Sixty-four BQD individuals and 47 gender- and age-matched healthy controls (HCs) underwent functional magnetic resonance imaging and a series of neuropsychological assessments. The dFC was constructed by calculating the Pearson correlation coefficients within a sliding window and was clustered into three functional connectivity states using k-means clustering. The dFC temporal properties derived from the cluster results were compared between the BQD and HC groups. The results showed that States 1 and 3 featured more frequent and weak connectivity, and State 2 featured less frequent and strong connectivity. There were significant differences for mean dwell time (MDT) in State 3 (p = 0.022) and fraction of time in State 2 (p = 0.018) between the BQD and HC groups. Pearson correlation analyses showed that the MDT in State 1 was negatively correlated with long delay free recall and short delay free recall, and the MDT in State 3 was positively correlated with false positive of long delay recall. Our findings provide strong evidence that MDT match the memory performance and suggest new insights into the pathophysiological mechanism of memory disorders in BQD individuals.
RESUMO
Betel quid (BQ) ranks fourth in global self-administered psychoactive agents, after caffeine, alcohol and nicotine, with 600 million consumers. Patients with BQ dependence (BQD) disorder demonstrate deficits in executive function. However, the neural correlates of the resting-state executive control network (ECN) and BQD-related pathopsychological characteristics still remain unclear. The present study aimed to assess the functional and effective connectivity of the ECN using resting-state functional magnetic resonance imaging (rs-fMRI). Fifty-five BQD individuals and 54 healthy controls (HCs) were recruited in this study. The executive function of all participants was tested by three tasks. Independent component and Granger causal analysis were employed to investigate the functional connectivity within ECN and ECN-related directional effective connectivity, separately. Behavioural results suggested a marked deficit of executive function in BQD individuals. Compared with HCs, BQD individuals showed overall weaker functional connectivity in the ECN, mainly including dorsolateral prefrontal cortex (DLPFC), inferior parietal lobule (IPL) and middle frontal gyrus (MFG). We observed decreased outflow of information from the right DLPFC and IPL to the precentral/pre-supplement motor area (SMA) and increased outflow of information from the MFG to the middle occipital gyrus in BQD individuals. Correlation analysis revealed that the effective connectivity from IPL to precentral/pre-SMA was negatively correlated to the BQD scales in BQD individuals. Our findings revealed impaired executive function, functional connectivity of the ECN and causal interaction between networks in patients with BQD. These results could potentially direct future targets for the prevention and intervention of BQD.

BACKGROUND: Betel quid (BQ) chewing is associated with poor oral hygiene, psychological impairment, and acute and long-term addictive effects, resulting in worse oral-related quality of life (OHRQoL). The purpose of this study was to characterize the factors associated with OHRQoL among BQ users receiving oral mucosal screening. METHODS: A cross-sectional study was conducted. Data were collected by random sampling of BQ users who visited outpatient departments receiving oral mucosal screening in a medical center Taiwan. The oral health assessment tool, the state anxiety inventory, the betel quid dependence scale, and the oral health impact profile were used to measure oral health status, anxiety, BQ dependence, and OHRQoL, respectively. Pearson's product-moment coefficient was used to examine the relationship between OHRQoL and the selected independent variables. Independent-samples t-test was used to compare OHRQoL by annual family income, the presence of chronic disease, and BQ dependence. Hierarchical multiple linear regression analysis was used to identify factors associated with OHRQoL. RESULTS: A total of 175 BQ users were surveyed. Factors associated with OHRQoL included oral health status, anxiety, and BQ dependence. BQ users reporting low oral health status, greater anxiety, and more BQ dependence were more likely to have worse OHRQoL. CONCLUSIONS: Poor oral health status, anxiety, and BQ dependence negatively impact on OHRQoL among patients with BQ use receiving oral mucosal screening.

Background: In India, indigenous populations, known as Tribes, are among the poorest and most marginalized groups. We estimated the prevalence of smoking, alcohol use, and betel quid chewing and examined the association between gender and smoking, alcohol use, and betel quid chewing among Kattunayakan primitive Tribes who are categorized as a Particularly Vulnerable Tribal Group (PVTG) in the Kerala State of India.Methods: A secondary analysis of a sample of the Wayanad District Tribal Household survey comprising 388 Kattunayakan PVTG households selected through multistage cluster random sampling was undertaken. Binary logistic regression models were used to estimate an association between gender and smoking, alcohol use, and betel quid chewing in these Tribal households.Results: Mean age was 39.2 years (±15.1), more than three-fourths of the respondents were female (75.3%), and approximately 24% of the respondents reported smoking tobacco in past 12 months. A fivefold increased odds of smoking among males compared to smoking among females was observed (OR = 4.92; p < .01). More than 64% reported betel quid chewing. Prevalence of alcohol use was 16%, which significantly varied between males (49%) and females (5.1%; OR = 17.71; p < .01). Among tobacco smokers, 64.1% were involved in betel quid use. Among alcohol users, 62.9% were involved in betel quid use and more than 58% were smoking tobacco. Betel quid chewing was the most prevalent substance use.Conclusion: Single and dual substance use of the three commonest types were disproportionately high among this hard-to-reach Tribal population in the southern state of India, with some gender variations. Alcohol consumption was relatively low. However, the complex nature of substance use, compounded by inaccessible health services, poses a significant challenge to rethink and to reimagine innovative methods of providing mental health care services, for instance, mobile health clinics.
RESUMO
Areca nut (AN) is consumed by millions of people for its therapeutic and psychoactive effects, making it one of the most widely self-administered psychoactive substances in the world. Even so, AN use/abuse is associated with myriad oral and systemic side effects, affecting most organ systems in the body. Alkaloids abundant in the nut (e.g. arecoline, arecaidine, guvacoline, and guvacine), collectively called the areca alkaloids, are presumably responsible for the major pharmacological effects experienced by users, with arecoline being the most abundant alkaloid with notable toxicological properties. However, the mechanisms of arecoline and other areca alkaloid elimination in humans remain poorly documented. Therefore, the purpose of this review is to provide an in-depth review of areca alkaloid pharmacokinetics (PK) in biological systems, and discuss mechanisms of metabolism by presenting information found in the literature. Also, the toxicological relevance of the known and purported metabolic steps will be reviewed. In brief, several areca alkaloids contain a labile methyl ester group and are susceptible to hydrolysis, although the human esterase responsible remains presumptive. Other notable mechanisms include N-oxidation, glutathionylation, nitrosamine conversion, and carbon-carbon double-bond reduction. These metabolic conversions result in toxic and sometimes less-toxic derivatives. Arecoline and arecaidine undergo extensive metabolism while far less is known about guvacine and guvacoline. Metabolism information may help predict drug interactions with human pharmaceuticals with overlapping elimination pathways. Altogether, this review provides a first-of-its-kind comprehensive analysis of AN alkaloid metabolism, adds perspective on new mechanisms of metabolism, and highlights the need for future metabolism work in the field.

The use of areca nuts (areca) in the form of betel quids constitutes the fourth most common addiction in the world, associated with high risk for oral disease and cancer. Areca is a complex natural product, making it difficult to identify specific components associated with the addictive and carcinogenic properties. It is commonly believed that the muscarinic agonist arecoline is at the core of the addiction. However, muscarinic receptor activation is not generally believed to support drug-taking behaviour. Subjective accounts of areca use include descriptions of both sedative and stimulatory effects, consistent with the presence of multiple psychoactive agents. We have previously reported partial agonism of α4-containing nicotinic acetylcholine receptors by arecoline and subsequent inhibition of those receptors by whole areca broth. In the present study, we report the inhibition of nicotinic acetylcholine receptors and other types of neurotransmitter receptors with compounds of high molecular weight in areca and the ability of low molecular weight areca extract to activate GABA and glutamate receptors. We confirm the presence of a high concentration of GABA and glutamate in areca. Additionally, data also indicate the presence of a dopamine and serotonin transporter blocking activity in areca that could account for the reported stimulant and antidepressant activity. Our data suggest that toxic elements of high molecular weight may contribute to the oral health liability of betel quid use, while two distinct low molecular weight components may provide elements of reward, and the nicotinic activity of arecoline contributes to the physical dependence of addiction.

BACKGROUND: Although betel quid chewing with tobacco use is one of the major behavioral risk factors for chronic diseases, the prevalence is rather on the increase in Myanmar. This study determined prevalence of betel quid chewing at the national and subnational levels and its associations with tobacco and sociodemographic factors. METHODS: This study is a secondary data analysis of Myanmar demographic health survey 2015-2016 with a total of 11 773 women and 4251 men aged 18-49 years. Chi-square tests and multivariable logistic regression tests were performed. RESULTS: Prevalence of betel quid chewing was 61.8% in men and 19.5% in women and by regions it ranged from 34 to 82.2% and from 5-8 to 52.9%, respectively. The prevalence of the concurrent use with tobacco was 25.8 and 2.3%, respectively. Women with older age, low education and low wealth and occupation and living with spouse were associated with betel quid chewing, while low education, living with spouse and Myanmar speaker were associated with men. Tobacco use was inversely and positively associated with betel quid chewing in men and women, respectively (P-interaction <0.0001). CONCLUSION: Implementation of culturally sensitive intervention and policies including effective community awareness campaigns for anti-betel quid chewing is strongly recommended in Myanmar.

OBJECTIVE: The current study asked whether BQ dependence level could affect working memory (WM) and remote memory for the chewers with concurrent use of cigarettes and alcohol, a common phenomenon in Taiwan. METHODS: The standardized neuropsychological tests (Wechsler Memory Scale III (WMS-III) and Remote Memory Test) were adopted to address the BQ chewers' verbal WM, spatial WM and remote memory. The Spatial Span Test and the Digit Span Test from WMS-III and the Remote Memory Test were adopted. The Betel Nut Dependency Scale (BNDS), the Fagerstrom Test for Nicotine Dependence (FTND), and the Alcohol Use Disorders Identification Test (AUDIT) were adopted to measure the dependence levels. RESULTS: The BQ dependence level and Last BQ did not affect spatial WM, verbal WM, and remote memory. Last Cigarette is critical in affecting WM; namely, longer interval led to worse performance. Finally, higher alcohol dependence level could lead to better remote memory. CONCLUSIONS: To our knowledge, there are no BQ studies addressing the effects of concurrent use of cigarettes and alcohol on memory. The current results suggest that cigarette smoking and alcohol drinking, rather than BQ chewing, are critical for memory performance.

Betel quid (BQ) is a package of mixed constituents that is chewed by more than 600 million people worldwide, particularly in Asia. The formulation of BQ depends on a variety of factors but typically includes areca nut, betel leaf, and slaked lime and may or may not contain tobacco. BQ chewing is strongly associated with the development of potentially malignant and malignant diseases of the mouth such as oral submucous fibrosis (OSMF) and oral squamous cell carcinoma (OSCC), respectively. We have shown recently that the constituents of BQ vary geographically and that the capacity to induce disease reflects the distinct chemical composition of the BQ. In this review, we examined the diverse chemical constituents of BQ and their putative role in oral carcinogenesis. Four major areca alkaloids-arecoline, arecaidine, guvacoline and guvacine-together with the polyphenols, were identified as being potentially involved in oral carcinogenesis. Further, we propose that fibroblast senescence, which is induced by certain BQ components, may be a key driver of tumour progression in OSMF and OSCC. Our study emphasizes that the characterization of the detrimental or protective effects of specific BQ ingredients may facilitate the development of targeted BQ formulations to prevent and/or treat potentially malignant oral disorders and oral cancer in BQ users.

BACKGROUND: Betel quid (BQ) is the fourth most commonly used psychoactive substance and its use is highly prevalent among southeast Asian countries due to the influence of psychosocial, behavioral, and environmental factors. As a result, even young children and women are becoming addicted and find it difficult to achieve long-term abstinence. Systematic research addressing the influence of behavioral and psychosocial factors on BQ chewing is scarce, hence pointing to the need for understanding the interplay of these factors to develop tailored intervention strategies for BQ cessation. OBJECTIVE: The objective of this systematic review is to assess various behavioral and psychosocial risk factors from pre-existing literature that lead individuals to initiate and/or maintain BQ chewing in developed and developing countries. MATERIALS AND METHODS: The electronic retrieval systems and databases PUBMED [MEDLINE], EMBASE, SCOPUS, WEB OF SCIENCE, GOOGLE SCHOLAR, and SCIENCE DIRECT were searched independently by two authors for relevant articles from January 2011 to July 2021 using combinations of keywords. Primary studies published in English focusing on the behavioral and psychosocial risk factors for BQ chewing were included. RESULTS: Out of the initial 264 articles searched, 12 articles met the selection criteria. Included studies addressed the influence of behavioral and psychosocial factors toward the initiation and/or maintenance of BQ chewing. Included studies reported that dependent BQ was not able to quit BQ chewing due to habituation, addiction, and withdrawal symptoms. Few social BQ chewers in Southeast Asian countries were not willing to initiate quitting as they considered AN as an important social and cultural identifier and claimed that they could not resist chewing in a peer group, and it has become part of their social life. CONCLUSION: In the future, studies should take into consideration behavioral and psychosocial risk factors, which are major barriers toward successful quitting. These factors should be integrated into areca nut cessation guidelines, and there is a need to develop more comprehensive culture-specific intervention approaches to achieve long-term abstinence.
