Time-discounting and tobacco smoking: a systematic review and network analysis.

ABSTRACT:

Background

Tobacco smoking harms health, so why do people smoke and fail to quit? An explanation originating in behavioural economics suggests a role for time-discounting, which describes how the value of a reward, such as better health, decreases with delay to its receipt. A large number of studies test the relationship of time-discounting with tobacco outcomes but the temporal pattern of this relationship and its variation according to measurement methods remain unclear. We review the association between time-discounting and smoking across (i) the life course, from initiation to cessation, and (ii) diverse discount measures.

Methods

We identified 69 relevant studies in Web of Science and PubMed. We synthesized findings across methodologies and evaluated discount measures, study quality and cross-disciplinary fertilization.

Results

In 44 out of 54 studies, smokers more greatly discounted the future than non-smokers and, in longitudinal studies, higher discounting predicted future smoking. Smokers with lower time-discount rates achieved higher quit rates. Findings were consistent across studies measuring discount rates using hypothetical monetary or cigarette reward scenarios. The methodological quality of the majority of studies was rated as 'moderate' and co-citation analysis revealed an isolation of economics journals and a dearth of studies in public health.

Conclusion

There is moderate yet consistent evidence that high time-discounting is a risk factor for smoking and unsuccessful cessation. Policy scenarios assuming a flat rate of population discounting may inadequately capture smokers' perceptions of costs and benefits.

Unhealthy diets, obesity and time discounting: a systematic literature review and network analysis.

Project description:There is an increasing policy commitment to address the avoidable burdens of unhealthy diet, overweight and obesity. However, to design effective policies, it is important to understand why people make unhealthy dietary choices. Research from behavioural economics suggests a critical role for time discounting, which describes how people's value of a reward, such as better health, decreases with delay to its receipt. We systematically reviewed the literature on the relationship of time discounting with unhealthy diets, overweight and obesity in Web of Science and PubMed. We identified 41 studies that met our inclusion criteria as they examined the association between time discount rates and (i) unhealthy food consumption; (ii) overweight and (iii) response to dietary and weight loss interventions. Nineteen out of 25 cross-sectional studies found time discount rates positively associated with overweight, obesity and unhealthy diets. Experimental studies indicated that lower time discounting was associated with greater weight loss. Findings varied by how time discount rates were measured; stronger results were observed for food than monetary-based measurements. Network co-citation analysis revealed a concentration of research in nutrition journals. Overall, there is moderate evidence that high time discounting is a significant risk factor for unhealthy diets, overweight and obesity and may serve as an important target for intervention. © 2016 The Authors Obesity Reviews published by John Wiley & Sons Ltd on behalf of International Association for the Study of Obesity (IASO).

Tobacco smoking and risk of endometriosis: a systematic review and meta-analysis.

Project description:ObjectiveSince conflicting results have been published on the role of tobacco smoking on the risk of endometriosis, we provide an up-to-date summary quantification of this potential association.DesignWe performed a PubMed/MEDLINE search of the relevant publications up to September 2014, considering studies on humans published in English. We searched the reference list of the identified papers to find other relevant publications. Case-control as well as cohort studies have been included reporting risk estimates on the association between tobacco smoking and endometriosis. 38 of the 1758 screened papers met the inclusion criteria. The selected studies included a total of 13,129 women diagnosed with endometriosis.SettingAcademic hospitals.Main outcome measureRisk of endometriosis in tobacco smokers.ResultsWe obtained the summary estimates of the relative risk (RR) using the random effect model, and assessed the heterogeneity among studies using the ?(2) test and quantified it using the I(2) statistic. As compared to never-smokers, the summary RR were 0.96 (95% CI 0.86 to 1.08) for ever smokers, 0.95 (95% CI 0.81 to 1.11) for former smokers, 0.92 (95% CI 0.82 to 1.04) for current smokers, 0.87 (95% CI 0.70 to 1.07) for moderate smokers and 0.93 (95% CI 0.69 to 1.26) for heavy smokers.ConclusionsThe present meta-analysis provided no evidence for an association between tobacco smoking and the risk of endometriosis. The results were consistent considering ever, former, current, moderate and heavy smokers, and across type of endometriosis and study design.

Motives, beliefs and attitudes towards waterpipe tobacco smoking: a systematic review.

Project description:BACKGROUND: In spite of the negative health effects of waterpipe tobacco smoking, its use is becoming more common. The objective of this study is to systematically review the medical literature for motives, beliefs and attitudes towards waterpipe tobacco smoking. METHODS: We electronically searched MEDLINE, EMBASE, and the ISI the Web of Science in January 2012. We included both quantitative and qualitative studies. We selected studies and abstracted data using standard systematic review methodology. We synthesized data qualitatively. RESULTS: We included 58 papers reporting on 56 studies. The main motives for waterpipe tobacco smoking were socializing, relaxation, pleasure and entertainment. Peer pressure, fashion, and curiosity were additional motives for university and school students while expression of cultural identity was an additional motive for people in the Middle East and for people of Middle Eastern descent in Western countries. Awareness of the potential health hazards of waterpipe smoking was common across settings. Most but not all studies found that the majority of people perceived waterpipe smoking as less harmful than cigarette smoking. Waterpipe smoking was generally socially acceptable and more acceptable than cigarette smoking in general. In Middle Eastern societies, it was particularly more acceptable for women's use compared to cigarette use. A majority perceived waterpipe smoking as less addictive than cigarette smoking. While users were confident in their ability to quit waterpipe smoking at any time, willingness to quit varied across settings. CONCLUSIONS: Socializing, relaxation, pleasure and entertainment were the main motives for waterpipe use. While waterpipe users were aware of the health hazards of waterpipe smoking, they perceived it as less harmful, less addictive and more socially acceptable than cigarette smoking and were confident about their ability to quit.

Current prevalence pattern of tobacco smoking in Nigeria: a systematic review and meta-analysis.

Project description:BACKGROUND:National smoking cessation strategies in Nigeria are hindered by lack of up-to-date epidemiologic data. We aimed to estimate prevalence of tobacco smoking in Nigeria to guide relevant interventions. METHODS:We conducted systematic search of publicly available evidence from 1990 through 2018. A random-effects meta-analysis and meta-regression epidemiologic model were employed to determine prevalence and number of smokers in Nigeria in 1995 and 2015. RESULTS:Across 64 studies (n =?54,755), the pooled crude prevalence of current smokers in Nigeria was 10.4% (9.0-11.7) and 17.7% (15.2-20.2) for ever smokers. This was higher among men compared to women in both groups. There was considerable variation across geopolitical zones, ranging from 5.4% (North-west) to 32.1% (North-east) for current smokers, and 10.5% (South-east) to 43.6% (North-east) for ever smokers. Urban and rural dwellers had relatively similar rates of current smokers (10.7 and 9.1%), and ever smokers (18.1 and 17.0%). Estimated median age at initiation of smoking was 16.8?years (IQR: 13.5-18.0). From 1995 to 2015, we estimated an increase in number of current smokers from 8 to 11 million (or a decline from 13 to 10.6% of the population). The pooled mean cigarettes consumption per person per day was 10.1 (6.1-14.2), accounting for 110 million cigarettes per day and over 40 billion cigarettes consumed in Nigeria in 2015. CONCLUSIONS:While the prevalence of smokers may be declining in Nigeria, one out of ten Nigerians still smokes daily. There is need for comprehensive measures and strict anti-tobacco laws targeting tobacco production and marketing.

The prevalence and trends of waterpipe tobacco smoking: A systematic review.

Project description:Waterpipe tobacco smoking is harmful to health however its prevalence estimates remain uncertain. We aimed to systematically review the medical literature on waterpipe tobacco prevalence and trends.We searched Medline, Embase and ISI Web of Science for 'waterpipe' and its synonyms, without using language or date restrictions. We included any measure of waterpipe tobacco smoking prevalence in jurisdictionally representative populations. We stratified findings by prevalence measure (past 30 day, ever, regular or occasional, daily, other or unspecified) and age (adults or youth).We included 129 studies reporting 355 estimates for 68 countries. In general, prevalence estimates among adults were highest in the Eastern Mediterranean, and among youth were about equal between Eastern Mediterranean and European regions. Past 30 day use was highest among Lebanese youth (37.2% in 2008), ever use was highest among Lebanese youth in 2002 and Lebanese university students in 2005 (both 65.3%), regular or occasional use was highest in among Iranian university students (16.3% in 2005), and daily use was highest among Egyptian youth (10.4% in 2005). Trend data were limited but most studies reported increased use over time, ranging from 0.3-1.0% per year among youth in the US to 2.9% per year among youth in Jordan (both for past 30 day use). Results were similar for ever use trends. Turkey (2.3% in 2008 to 0.8% in 2010) and Iraq (6.3% in 2008 and 4.8% in 2012) both witnessed decreased waterpipe use.Waterpipe tobacco smoking is most prevalent in Eastern Mediterranean and European countries, and appears higher among youth than adults. Continued surveillance will be important to assess and inform policy measures to control waterpipe tobacco use.

Interventions for waterpipe tobacco smoking prevention and cessation: a systematic review.

Project description:Waterpipe tobacco smoking is growing in popularity despite adverse health effects among users. We systematically reviewed the literature, searching MEDLINE, EMBASE and Web of Science, for interventions targeting prevention and cessation of waterpipe tobacco smoking. We assessed the evidence quality using the Cochrane (randomised studies), GRADE (non-randomised studies) and CASP (qualitative studies) frameworks. Data were synthesised narratively due to heterogeneity. We included four individual-level, five group-level, and six legislative interventions. Of five randomised controlled studies, two showed significantly higher quit rates in intervention groups (bupropion/behavioural support versus placebo in Pakistan; 6 month abstinence relative risk (RR): 2.3, 95% CI 1.4-3.8); group behavioural support versus no intervention in Egypt, 12 month abstinence RR 3.3, 95% CI 1.4-8.9). Non-randomised studies showed mixed results for cessation, behavioural, and knowledge outcomes. One high quality modelling study from Lebanon calculated that a 10% increase in waterpipe tobacco taxation would reduce waterpipe tobacco demand by 14.5% (price elasticity of demand -1.45). In conclusion, there is a lack of evidence of effectiveness for most waterpipe interventions. While few show promising results, higher quality interventions are needed. Meanwhile, tobacco policies should place waterpipe on par with cigarettes.

The Effect of Tobacco Smoking on Musculoskeletal Health: A Systematic Review.

Project description:This systematic review explored associations between smoking and health outcomes involving the musculoskeletal system. AMSTAR criteria were followed. A comprehensive search of PubMed, Web of Science, and Science Direct returned 243 articles meeting inclusion criteria. A majority of studies found smoking has negative effects on the musculoskeletal system. In research on bones, smoking was associated with lower BMD, increased fracture risk, periodontitis, alveolar bone loss, and dental implant failure. In research on joints, smoking was associated with increased joint disease activity, poor functional outcomes, and poor therapeutic response. There was also evidence of adverse effects on muscles, tendons, cartilage, and ligaments. There were few studies on the musculoskeletal health outcomes of secondhand smoke, smoking cessation, or other modes of smoking, such as waterpipes or electronic cigarettes. This review found evidence that suggests tobacco smoking has negative effects on the health outcomes of the musculoskeletal system. There is a need for further research to understand mechanisms of action for the effects of smoking on the musculoskeletal system and to increase awareness of healthcare providers and community members of the adverse effects of smoking on the musculoskeletal system.

The downside of tobacco control? Smoking and self-stigma: A systematic review.

Project description:Little is known about the consequences of tobacco smoking stigma on smokers and how smokers may internalize smoking-related stigma. This review summarizes existing literature on tobacco smoking self-stigma, investigating to what extent smokers are aware of negative stereotypes, agree with them and apply them to themselves.We carried out a systematic search of Pubmed/Web of Science/PsycInfo databases for articles related to smoking self-stigma through June 2013. Reference lists and citations of included studies were also checked and experts were contacted. After screening articles for inclusion/exclusion criteria we performed a quality assessment and summarized findings according to the stages of self-stigma as conceptualized in Corrigan's progressive model of self-stigma (aware, agree, apply and harm). Initial searches yielded 570 articles.Thirty of these articles (18 qualitative and 12 quantitative studies) met criteria for our review. Awareness of smoking stigma was virtually universal across studies. Coping strategies for smoking stigma and the degree to which individuals who smoke internalized this stigma varied both within and across studies. There was considerable variation in positive, negative, and non-significant consequences associated with smoking self-stigma. Limited evidence was found for subgroup differences in smoking-related stigma.While there is some evidence that smoking self-stigma leads to reductions in smoking, this review also identified significant negative consequences of smoking self-stigma. Future research should assess the factors related to differences in how individuals respond to smoking stigma. Public health strategies which limit the stigmatization of smokers may be warranted.

Factors associated with tobacco smoking among Saudi college students: A systematic review.

Project description:IntroductionThere has been an increase in tobacco smoking among Saudi college students in recent years. However, no study has examined, with a systematic approach, the extent to which specific factors are associated with tobacco smoking among this population.MethodsPubMed, ProQuest, CINAHL, and Web of Science were utilized to retrieve studies addressing risk factors associated with tobacco smoking among Saudi college students between 2010 and 2019. After confirming their eligibility criteria, studies were imported to the NVivo software for data collection and synthesis. All included articles were critically appraised, based on a modified STROBE.ResultsTwenty-one out of 300 studies met the eligibility requirements for inclusion. Riyadh was the location, health-related science was the field of study, and male the gender of the population of most of the included studies. Only one study used a longitudinal design based on a theoretical framework, the rest were cross-sectional and lacked theoretical utilization. Four individual and two social factors were established to have a significant relationship with tobacco smoking behavior among college students in four or more studies. Environmental factors were found to be associated with a change in smoking behavior among Saudi college students based on two studies.ConclusionsThere is a dearth of research in utilizing theoretical frameworks to guide the research in order to propose an intervention program among Saudi college students. Future research should aim to recruit participants from different institutions in the Kingdom of Saudi Arabia (KSA), apply other methodological approaches, test other measurements of tobacco smoking, and utilize a theoretical framework.

Unstuck in time: episodic future thinking reduces delay discounting and cigarette smoking.

Project description:RationaleDelay discounting, or the devaluation of delayed outcomes, appears to play an etiological role in tobacco and other substance-use disorders.ObjectivesNo human studies to our knowledge have been designed to examine whether experimental reductions in delay discounting produce concomitant reduction in drug use.MethodsUsing methods from prior studies on delay discounting and obesity, we examined the effects of episodic future thinking (EFT; a form of mental prospection) on delay discounting and cigarette self-administration in smokers.ResultsConsistent with prior data, EFT significantly reduced both delay discounting (Cohen's d effect size = 0.65) and the number of cigarette puffs earned in a cigarette self-administration task (d = 0.58).ConclusionsThe effects of EFT on delay discounting generalize to smokers; EFT also reduces laboratory-based cigarette self-administration. Potential mechanisms of EFT's effects are discussed as well as implications of EFT for clinical treatment of substance-use disorders.
