Previous studies have identified variants in genes encoding proteins associated with the degree of addiction, smoking onset, and cessation. We aimed to describe thirty-one single nucleotide polymorphisms (SNPs) in seven candidate genomic regions spanning six genes associated with tobacco-smoking in a cross-sectional study from two different interventions for quitting smoking: (1) thirty-eight smokers were recruited via multimedia to participate in e-Decídete! program (e-Dec) and (2) ninety-four attended an institutional smoking cessation program on-site. SNPs genotyping was done by real-time PCR using TaqMan probes. The analysis of alleles and genotypes was carried out using the EpiInfo v7. on-site subjects had more years smoking and tobacco index than e-Dec smokers (p < 0.05, both); in CYP2A6 we found differences in the rs28399433 (p < 0.01), the e-Dec group had a higher frequency of TT genotype (0.78 vs. 0.35), and TG genotype frequency was higher in the on-site group (0.63 vs. 0.18), same as GG genotype (0.03 vs. 0.02). Moreover, three SNPs in NRXN1, two in CHRNA3, and two in CHRNA5 had differences in genotype frequencies (p < 0.01). Cigarettes per day were different (p < 0.05) in the metabolizer classification by CYP2A6 alleles. In conclusion, subjects attending a mobile smoking cessation intervention smoked fewer cigarettes per day, by fewer years, and by fewer cumulative pack-years. There were differences in the genotype frequencies of SNPs in genes related to nicotine metabolism and nicotine dependence. Slow metabolizers smoked more cigarettes per day than intermediate and normal metabolizers.

For improving accomplished attempts to stop smoking, it is necessary to learn about the qualities of individuals who can willingly stop smoking. This study seeks to discover the willingness degree and associated determinants to stop smoking between adult visitors of a primary healthcare centre in an urban area of Alexandria in Egypt. In this single point and descriptive cross-sectional study, a semi-structured questionnaire was distributed to a sample of 53 adults aged ≥18 years in May 2019. Descriptive statistical analyses were conducted to evaluate the determinants influencing the willingness to stop smoking. Of the 53 respondents (with a mean age of 38.7 years old), 41.5% of them were males. Almost 18.9% of the respondents were ongoing smokers (36.4% of males and 6.5% of females), though 83.7% of those smokers were willing to stop smoking. The number of male smokers was significantly greater than female smokers (Pearson Chi-Square = 7.52, p-value = 0.006). Determinants, which can favourably influence the willingness to stop smoking, were believing that smoking is a health risk to them (100%) and the others around (94.3%). A bulk of participants (56.6%) doubted the need for nicotine supplements to help in smoking cessation. Smoker respondents were willing to stop smoking. Understanding that smoking is a health hazard for both smokers and the others around can motivate smoking cessation. Relying on nicotine supplements alone might not add favourably to a strong smoking cessation decision. Tailoring campaigns to raise awareness about smoking health hazards’ would support and sustain smoking cessation.

Background - In recent years there has been a proliferation of alternative tobacco and nicotine products that reduce consumers’ exposure to harmful substances and therefore have the potential to reduce risk to health. Post-market surveillance enables the evaluation of newly introduced tobacco and nicotine products (aka potentially reduced risk products (PRRPs)) at a population level. This study aims to investigate tobacco and nicotine consumer demographics and discover how people are using these products, and characterise behavioral trends as transitions between tobacco heated products (THPs) and other nicotine products. These behavioural aspects, in conjunction with the intrinsic risk of the product, are essential for assessing the potential health effects and establishing a population risk assessment. Design and methods - This epidemiological cross-sectional study will collect data using a self-administered study instrument from the general Japanese population aged 20 years and older. The targeted sampling size is up to 5,000 participants per study wave. The study addresses the following objectives: estimation of tobacco and nicotine use prevalence; characterisation of  product usage by product type; changes in use behaviour in general, with particular emphasis on the introduction of THPs in the time period of one year; risk perceptions of different tobacco products and no tobacco usage; and participant perceived health status and quality of life. Discussion - The description of tobacco and nicotine product use behaviour, the estimation of prevalence data, the measuring of product-specific risk perception and the change of tobacco use behaviour within one year will allow for a comprehensive assessment of the effect of introducing THPs into a market. These data could also be used to inform a system dynamics population model in order to estimate the public health impact of introducing a THP into the Japanese market.

Abstract Background: Health-care systems have primary responsibility for treating tobacco dependence. Despite its proven effectiveness, international studies have shown that provision of smoking cessation advice to patients in primary health care is suboptimal. This study aimed at assessing Palestinian PHC physicians' compliance and attitude towards smoking cessation counseling and their determinants.Methods: the study utilized a cross-sectional study design using a self-reported questionnaire targeted general practitioners, family medicine doctors, obstetrics & gynecologists and dentists working at PHC Centers in Palestine in the period between April to September,2019. Proportionate stratified random sampling method was used. Sociodemograpic, medical experience, if received any training in smoking cessation counseling, smoking history, practice compliance, knowledge, confidence and attitude were assessed. Results: 294 PHC physicians' participated in the study with high response rate. More than a half (53%) were between 31-45 years of age. Most of them (76.5%) were general practitioners seeing more than 30 patients per day (66%) and only 15% (n=40) get training about smoking cessation counseling. Practice compliance was low; only 39 (13.3%) reported compliance to smoking cessation practice. Attitude level among the participant physicians was good as the overall attitude score mean was 75.1 ± 9.6. Positive attitude, assigned as any score ≥65, was observed in 87.7% (n=258) of physicians. Job title, experience and knowledge are predictors of positive attitude towards smoking cessation counseling.Conclusion: Building supportive environment, improving physicians’ capabilities will reflect on their self-efficacy and their con­fidence level and will improve their practice in smoking cessation counseling.
