Barriers to Quitting Areca Nut Consumption and Joining a Cessation Program as Perceived by Chewer and Nonchewer Populations in Guam.

ABSTRACT: Background: Areca nut (AN) is a carcinogenic substance consumed by roughly 600 million individuals worldwide with increasing popularity in Guam. In response, a cessation program was developed and implemented in Guam and Saipan. However, to improve its delivery, it is necessary to understand the reasons influencing recruitment and participation, such as why a chewer may not want to quit or join a cessation program. Objective: To explore barriers inhibiting chewers from quitting AN chewing and from participating in a cessation program. Methods: Nine individual and group discussions were facilitated with a convenience sample of 17 chewers and nonchewers in Guam in 2017. The mean age of the participants was 36.4?years. Recurring themes relating to reasons for not quitting and not joining a cessation program were extracted. Results: Results produced three general categories-Sociocultural, Behavioral, and Accessible. Each category encompasses different attributes concerning reasons not to quit chewing (e.g. addiction, enabling community, or belief that AN is harmless), and reasons influencing lack of participation in a cessation program (e.g. time, transportation, or relatability). Conclusions: Current findings suggest chewers are unaware of the harmful effects of AN. Also, they may not comprehend the purpose of a cessation program. In addition, the likelihood of chewers participating in a cessation program is influenced by their level of comfort with the program and personnel, and whether a program addresses their time and transportation limitations.

Project description:INTRODUCTION:The use of betel quid is the most understudied major addiction in the world. The neuropsychological activity of betel quid has been attributed to alkaloids of Areca catechu. With the goal of developing novel addiction treatments, we evaluate the muscarinic and nicotinic activity of the four major Areca alkaloids: arecoline, arecaidine, guvacoline, and guvacine and four structurally related compounds. METHODS:Acetylcholine receptors were expressed in Xenopus oocytes and studied with two-electrode voltage clamp. RESULTS:Both arecoline- and guvacoline-activated muscarinic acetylcholine receptors (mAChR), while only arecoline produced significant activation of nicotinic AChR (nAChR). We characterized four additional arecoline-related compounds, seeking an analog that would retain selective activity for a α4* nAChR, with diminished effects on mAChR and not be a desensitizer of α7 nAChR. We show that this profile is largely met by isoarecolone. Three additional arecoline analogs were characterized. While the quaternary dimethyl analog had a broad range of activities, including activation of mAChR and muscle-type nAChR, the methyl analog only activated a range of α4* nAChR, albeit with low potency. The ethyl analog had no detectable cholinergic activity. CONCLUSIONS:Evidence indicates that α4* nAChR are at the root of nicotine addiction, and this may also be the case for betel addiction. Our characterization of isoarecolone and 1-(4-methylpiperazin-1-yl) ethanone as truly selective α4*nAChR selective partial agonists with low muscarinic activity may point toward a promising new direction for the development of drugs to treat both nicotine and betel addiction. IMPLICATIONS:Nearly 600 million people use Areca nut, often with tobacco. Two of the Areca alkaloids are muscarinic acetylcholine receptor agonists, and one, arecoline, is a partial agonist for the α4* nicotinic acetylcholine receptors (nAChR) associated with tobacco addiction. The profile of arecoline activity suggested its potential to be used as a scaffold for developing new tobacco cessation drugs if analogs can be identified that retain the same nicotinic receptor selectivity without muscarinic activity. We report that isoarecolone is a selective partial agonist for α4* nAChR with minimal muscarinic activity and 1-(4-methylpiperazin-1-yl) ethanone has similar nAChR selectivity and no detectable muscarinic action.
