Comparative epidemiology of betel nut use versus ecstasy use among Taiwanese adolescents: findings from a national survey

Betel Quid Health Risks of Insulin Resistance Diseases in Poor Young South Asian Native and Immigrant Populations

Betel quid, traditionally prepared with areca nut, betel leaf, and slaked lime, has been consumed for thousands of years, mainly in the form of chewing. Originally used for cultural, medicinal, and ceremonial purposes mainly in South Asian countries, its use has recently spread across the globe due to its psychoactive, euphoric, and aphrodisiac properties. Now it is widely used as a social lubricant and source of financial profit. Unfortunately, the profit motive has led to high rates of habitual consumption with eventual conversion to addiction among young girls and boys. Moreover, the worrisome practice of including tobacco in quid preparations has grown, particularly among pregnant women. Major health concerns include increased rates of malignancy, oral pathology, and cardiovascular, hepatic, fertility, metabolic, and neuropsychiatric disorders. Metabolic disorders and insulin resistance disease states such as type 2 diabetes, obesity, and metabolic syndrome contribute to cognitive decline and neurodegeneration. Mechanistically, the constituents of areca nut/betel quid are metabolized to N-nitroso compounds, i.e., nitrosamines, which are carcinogenic at high doses and cause insulin resistance following chronic low-level exposures. From an epidemiological perspective, the rising tide of insulin resistance diseases including obesity, diabetes, and dementias that now disproportionately burden poor countries has been propagated by rapid commercialization and enhanced access to betel quid. Public health measures are needed to impose socially and ethically responsible barriers to yet another cause of global health disparity.

Associations between Work Experience and Betel Nut, Alcohol, or Tobacco Use among Low-Income Taiwanese Students from Middle School to University

Background: Research suggests that young working students are at higher risk for substance use. However, most studies have focused on students from middle-class families, with few investigations conducted on substance use by students from low-income families. Objective: To examine the associations between work experience and betel nut, alcohol, or tobacco (BAT) use among Taiwanese students from low-income families. Methods: The data for this cross-sectional study were derived from the fourth wave of the Taiwan Panel Study of Children and Youth survey which provides primary data on low-income families. A total of 3,350 low-income students aged 12-25 years old from middle school to university participated. The χ² test was performed to examine differences in sociodemographic characteristics and BAT use between employed and unemployed students. Multivariate logistic regression was used to examine the associations between work status, work intensity, monthly income, occupation, and BAT use. Results: Employed students displayed higher BAT use than those who were unemployed. Increased BAT use was also associated with higher work intensity (except for betel nut use), higher monthly income, and specific occupations (such as service or manual work). Conclusions: Employment is independently associated with a higher risk of BAT use among low-income Taiwanese students. Work intensity and specific occupational fields may offer insights into formulating relevant preventive measures for these students.

Predictors of five-year relapse rates of youths with substance abuse who underwent a family-oriented therapy program

BACKGROUND

Substance abuse among young people has become a serious public health problem for years. The risk of relapse among illicit drug use is essential for developing adequate substance reuse prevention policies. The purpose of the current study is to investigate the potential predictor in long-term relapse rates among young patients that underwent a family-based treatment program.

METHODS

To perform this study, 103 young patients with substance use (mean age: 16.2 years, 78.6% male) were referred to participate in a 10-week family-based treatment program. At the beginning and at the end of the treatment, the patients were required to fill out the Chinese Craving Beliefs Questionnaire (CCBQ), the Adolescents' Behavior-problem Scale (ABS), and the Family APGAR. Furthermore, the patients' caregivers had to fill out the Family APGAR, the 12-item version of the Chinese Health Questionnaire (CHQ), and the Parenting Stress Index (PSI). All patients were followed up for 5 years in order to observe their long-term outcomes regarding substance use relapse.

RESULTS

During the 10-week family-oriented programs, the CCBQ scores, the CHQ scores and the Child-domain of PSI significantly decreased. Better changes in patients' behavioral problems during the treatment program predicted a lesser likelihood of substance use relapse in the subsequent 5 years. Furthermore, methamphetamine or 3,4-methylenedioxy-methamphetamine use and living in single-parent families were two factors associated with higher relapse rates.

CONCLUSIONS

The changes in patients' behavioral problems during the treatment program may serve as a predictor of substance use relapse over the subsequent 5 years. This study's findings provide insight about substance use prevention and serve as a reference for policy-making.

Residential Socioeconomic Environments and Areca Nut Use in Taiwan: A Comparison with Alcohol and Tobacco Use in Multilevel Analysis

While the association between residential socioeconomic environments and the use of globally common substances such as alcohol and tobacco has been well documented in Western countries, it remains little known about regionally important substances, such as areca nut in Asia. Objective: This study was aimed to develop residential environmental indicators in the context of Taiwan and examine their associations with areca nut use, in comparison to alcohol and tobacco use. Methods: Data were drawn from 13,392 adults across 168 townships in the 2014 National Survey on Substance Use in Taiwan. Residential socioeconomic environment variables were derived from the census and analyzed using factor analysis. Multilevel logistic regression models were used to examine the association of individual- and residential-level factors with the use of areca nut (use/nonuse), alcohol (harmful use, low-risk use, or nonuse), and tobacco (nicotine dependence, regular active use, or nonuse). Results: A three-factor structure of socioeconomic environments derived from 16 residential-level variables consisted of Rural Disadvantage, Affluence, and Family Fragmentation. Multilevel analyses showed that areca nut use was associated with both individual-level (male sex, age group 35-44 years, being divorced/widowed/separated, low educational attainment, and the occupational group of labors) and residential-level (Rural Disadvantaged and Family Fragmented) variables; such a profile was most similar to that of nicotine dependence. Conclusions: A three-factor structure could be derived for the residential-level socioeconomic environments in the Taiwanese context. Rural Disadvantaged and Family Fragmented were associated with areca nut use, which have implications for interventions targeted at the community level.

Taking actions to quit chewing betel nuts and starting a new life: taxi drivers' successful experiences of quitting betel nut chewing

AIMS AND OBJECTIVES

To understand taxi drivers' successful experiences of quitting betel nut chewing.

BACKGROUND

Previous studies verified that betel nut chewing significantly increases the risk of oral cancer. In Taiwan, taxi drivers work for approximately 10-13 hours per day, and 31·7-80% of them choose to chew betel nuts for their invigorating qualities, which enable them to work more hours and receive more income.

DESIGN

A qualitative research design was used.

METHODS

This study used the grounded theory method with purposive sampling to perform in-depth interviews with male taxi drivers who had successfully quit betel nut chewing for more than six months.

RESULTS

The interviewed participants were 25 taxi drivers aged 45-67 who had chewed betel nuts for an average of 30·9 years. A constant comparative analysis of the 25 interviews revealed six categories, namely the first experience of chewing betel nuts, a part of work and life, perceiving the impact of betel nuts, trying to change, acting to quit betel nut chewing and starting a new life.

CONCLUSIONS

During the cessation process, taxi drivers tended to be affected by their addiction to chewing betel nuts and the temptation of friends' invitations to chew betel nuts. However, their recognition of the physical effects of betel nut chewing and their sense of responsibility and commitment to family were the critical factors affecting their determination to quit betel nut chewing. Their willpower to not to chew betel nuts and the source of their motivation to exercise self-control also contributed to their success.

RELEVANCE TO CLINICAL PRACTICE

Healthcare personnel should understand the experiences and perceptions of betel nut chewers, strengthen their understanding of the effects of betel nut chewing on physical health during the cessation period and support their self-efficacy and quitting behaviours with the assistance of significant others.

A family-oriented therapy program for youths with substance abuse: long-term outcomes related to relapse and academic or social status

OBJECTIVE

The abuse of illegal substances by youths in Taiwan has become a major public health issue. This study explores the outcomes (relapse rate and academic or social status) of a family-oriented therapy program conducted for substance-using youths who were referred by a judge to participate in it.

METHODS

The present study includes 121 participants categorized into three groups: 36 youths underwent a weekly ten-session outpatient motivational enhancement psychotherapy (MEP) group program; 41 youths participated in a program that combined the aforementioned MEP program with an additional weekly ten-session parenting skill training (PST) program for their guardians (MEP + PST group); and 44 adolescents who received standard supervision by the court served as the control group. All participants were followed-up for a maximum of 2 years.

RESULTS

Of the 121 participants (mean age: 16.1±1.1 years), 33.1% relapsed into substance use during the follow-up period. The probability of relapse did not differ significantly between the MEP group (36.1%) and the control group (40.9%), but the youths in the MEP + PST group (22.0%) were at a lower risk of relapse than the control group participants (adjusted hazard ratio =0.48, 95% confidence interval [CI] =0.21-1.09). By the end of the study follow-up period, participants in both the MEP group and the MEP + PST group were more likely to be attending school (MEP group: adjusted odds ratio [aOR] =6.61, 95% CI =1.60-27.35; MEP + PST group: aOR =8.57, 95% CI =1.94-37.82) or employed (MEP group: aOR =7.75, 95% CI =1.95-30.75; MEP + PST group: aOR =7.27, 95% CI =1.76-29.97), when compared to the control group.

CONCLUSION

This study revealed that a family-oriented treatment approach may be a more effective option for preventing youths' relapsing into substance abuse. In comparison to individuals who received standard supervision by the court, those who received MEP experienced a better school attendance or social outcome over the follow-up period.

Sexual initiation and emotional/behavioral problems in Taiwanese adolescents: a multivariate response profile analysis

This study aimed to investigate the relations of adolescent sexual experiences (particularly early initiation) to a spectrum of emotional/behavioral problems and to probe possible gender difference in such relationships. The 10th (N = 8,842) and 12th (N = 10,083) grade students, aged 16-19 years, participating in national surveys in 2005 and 2006 in Taiwan were included for this study. A self-administered web-based questionnaire was designed to collect information on sociodemographic characteristics, sexual experience, substance use, and the Youth Self-Report Form. For the sexually experienced adolescents, their sexual initiation was classified as early initiation (<16 years) or non-early initiation (16-19 years). Gender-specific multivariate response profile regression was used to examine the relationship between sexual experience and the behavioral syndromes. Externalizing problems, including Rule-breaking Behavior and Aggressive Behavior, were strongly associated with sexual initiation in adolescence; the magnitude of the association increased for earlier sexual initiation, especially for females. As to internalizing problems, the connection was rather heterogeneous. The scores on some syndromes, such as Somatic Complaints and Anxious/Depressed, were higher only for females with early or non-early sexual initiation whereas the score on Withdrawn, along with Social Problems that is neither internalizing nor externalizing, was lower for the sexually experienced adolescents than for the sexually inexperienced ones. We concluded that earlier sexual initiation was associated with a wider range of behavioral problems in adolescents for both genders, yet the increased risk with emotional problems was predominately found in females.

Betel quid chewing without tobacco: a meta-analysis of carcinogenic and precarcinogenic effects

Betel quid without tobacco is an important factor influencing the incidences of oral cancer and precancer. This study systematically evaluated the associations between betel quid containing no tobacco and oral cancer and precancer, with implications for the prevention of oral cancer. We searched MEDLINE, ISI Web of Science, and EMBASE (to April 2011) and retrieved studies that investigated the relationship between chewing betel quid and oral cancer (or precancer). We performed a meta-analysis to summarize the published data and describe the prevalence of betel quid use with regard to cancerous diseases. In all, 19 eligible studies that reported odds ratios and 95% confidence intervals for oral cancer with respect to betel quid were included. The analysis identified an association suggesting that betel quid might be an important risk factor for oral cancer and precancer. The results of this review suggest that betel-chewing-cessation programs should be developed to help prevent oral diseases.

Availability of convenience stores and adolescent alcohol use in Taiwan: a multi-level analysis of national surveys

AIM

To examine the association between alcohol in school environments and adolescent alcohol use over the previous 6 months.

DESIGN

A multi-level logistic regression analysis was performed of cross-sectional surveys conducted in 2004, 2005 and 2006.

PARTICIPANTS AND SETTING

A total of 52 214 students aged 11-19 years from 387 middle or high schools were selected from a nationally representative, multi-stage, stratified probability sampling across Taiwan.

MEASUREMENTS

Information on socio-demographic features and substance use experiences was collected using self-administered questionnaires. The alcohol in the environment was measured using the availability of convenience stores surrounding the schools. Using geographical information systems, the weighted numbers of convenience stores within 1 km, a 12-15-minute walk, of a school were calculated. The schools were later categorized into three subgroups via the tertile of nearby convenience stores.

FINDINGS

Considering the compositional characteristics, the availability of convenience stores was found to account for 1.5% of the school-level variance of youthful drinking. The odds ratios (95% confidence interval) of alcohol use over the previous 6 months among youth attending schools with medium and high availability were 1.04 (0.96-1.13) and 1.08 (1.00-1.17), respectively, with a P-value of 0.04 in the trend test.

CONCLUSION

The greater availability of convenience stores near a school is associated with an increased risk of alcohol use among adolescents over the previous 6 months.
