Cigarette Smoking, Smoking Cessation, and Long-Term Risk of 3 Major Atherosclerotic Diseases.

ABSTRACT: BACKGROUND:Public statements about the effect of smoking on cardiovascular disease are predominantly based on investigations of coronary heart disease (CHD) and stroke, although smoking is recognized as a strong risk factor for peripheral artery disease (PAD). No study has comprehensively compared the long-term association of cigarette smoking and its cessation with the incidence of 3 major atherosclerotic diseases (PAD, CHD, and stroke). OBJECTIVES:The aim of this study was to quantify the long-term association of cigarette smoking and its cessation with the incidence of the 3 outcomes. METHODS:A total of 13,355 participants aged 45 to 64 years in the ARIC (Atherosclerosis Risk In Communities) study without PAD, CHD, or stroke at baseline (1987 to 1989) were included. The associations of smoking parameters (pack-years, duration, intensity, and cessation) with incident PAD were quantified and contrasted with CHD and stroke using Cox models. RESULTS:Over a median follow-up of 26 years, there were 492 PAD cases, 1,798 CHD cases, and 1,106 stroke cases. A dose-response relationship was identified between pack-years of smoking and 3 outcomes, with the strongest results for PAD. The pattern was consistent when investigating duration and intensity separately. A longer period of smoking cessation was consistently related to lower risk of PAD, CHD, and stroke, but a significantly elevated risk persisted up to 30 years following smoking cessation for PAD and up to 20 years for CHD. CONCLUSIONS:All smoking measures showed significant associations with 3 major atherosclerotic diseases, with the strongest effect size for incident PAD. The risk due to smoking lasted up to 30 years for PAD and 20 years for CHD. Our results further highlight the importance of smoking prevention and early smoking cessation, and indicate the need for public statements to take PAD into account when acknowledging the impact of smoking on overall cardiovascular health.

Project description:ImportanceSmoking cessation is frequently followed by weight gain; however, whether weight gain after quitting reduces the health benefits of quitting is unclear.ObjectiveTo examine the association between weight change after smoking cessation and the risk of cardiovascular diseases (CVD), type 2 diabetes, cancer, chronic obstructive pulmonary disease (COPD), and all-cause mortality.Design, setting, and participantsThis cohort study analyzed data from a nationally representative sample of Australian adults aged 18 years or older who were studied between 2006 and 2014. Smoking status and anthropometric measurements were self-reported annually. Cox proportional hazards regressions were used to determine the hazard ratios (HRs) for the association between changes in weight and body mass index (BMI) and the risk of CVD, type 2 diabetes, cancer, COPD, and mortality. Data were analyzed in January 2019.ExposuresAnnual self-reported smoking status; years since quitting.Main outcomes and measuresWeight gain after quitting, incident CVD, type 2 diabetes, cancer, COPD, and all-cause mortality.ResultsOf a total 16 663 participants (8082 men and 8581 women; mean [SD] age, 43.7 [16.3] years), those who quit smoking had greater increases in weight (mean difference [MD], 3.14 kg; 95% CI, 1.39-4.87) and BMI (MD, 0.82; 95% CI, 0.21-1.44) than continuing smokers. Compared with continuing smokers, the HRs for death were 0.50 (95% CI, 0.36-0.68) among quitters who lost weight, 0.79 (95% CI, 0.51-0.98) among quitters without weight change, 0.33 (95% CI, 0.21-0.51) among quitters who gained 0.1 to 5.0 kg, 0.24 (95% CI, 0.11-0.53) among quitters who gained 5.1 to 10 kg, and 0.36 (95% CI, 0.16-0.82) among quitters who gained more than 10 kg. The HRs for death were 0.61 (95% CI, 0.45-0.83) among quitters who lost BMI, 0.86 (95% CI, 0.51-1.44) among quitters without change in BMI, 0.32 (95% CI, 0.21-0.50) among quitters who gained up to 2 in BMI, and 0.26 (95% CI, 0.16-0.45) among quitters who gained more than 2 in BMI.Conclusions and relevanceThis cohort study found that smoking cessation was accompanied by a substantial weight gain; however, this was not associated with an increased risk of chronic diseases or an attenuation of the mortality benefit of cessation.

Project description:Many lifelong smokers establish smoking habits during young adulthood. A university can be an effective setting for early smoking cessation. We evaluated long-term predictors of smoking cessation among smokers in a university setting.We longitudinally followed a cohort of smokers enrolled in a university smoking cessation program in Seoul, South Korea. Sociodemographic factors, smoking-related variables, and changes in smoking habits were assessed during 6-week visit sessions and follow-up telephone interviews conducted 1 year or more later.A total of 205 participants were followed up (mean follow-up duration: 27.1 months). Cessation rates were 47.3% at the end of the visit sessions and 28.8% at follow-up. The long-term persistent smoking rate was significantly higher among individuals with peers who smoked (odds ratio [OR] = 8.64; 95% confidence interval [CI] = 1.75, 42.80), with family members who smoked (OR = 3.28; 95% CI = 1.20, 9.00), and who smoked 10 to 19 cigarettes/day (OR?=?4.83; 95% CI?=?1.49, 15.69). Conversely, persistent smoking was less likely among those who attended the program regularly (OR?=?0.84 per visit; 95% CI?=?0.72, 0.99) and attempted quitting more frequently (OR?=?0.93 per attempt; 95% CI?=?0.87, 0.99). Use of smoking cessation medications (varenicline or bupropion) was not significantly associated with long-term quitting (OR?=?0.71; 95% CI?=?0.26, 1.93).Peer influences were the strongest predictors of failure in long-term cessation among smokers who attempted to quit. Similarly, the existence of smokers in the family was negatively associated with successful quitting. Regular attendance at a smoking cessation program and a high number of attempts to quit were positively associated with successful quitting. Targeting peer and family smoking groups together rather than targeting individual smokers alone, implementing active cessation programs encouraging regular attendance, and providing comprehensive antismoking environments might be effective strategies in a university setting.

Project description:BackgroundTo investigate the association between cigarette smoking, smoking cessation and the trajectory of cardiometabolic multimorbidity (CMM), and further to examine the association of age at smoking initiation and smoking cessation with CMM.MethodsThis study included 298,984 UK Biobank participants without cardiometabolic diseases (CMDs) (including type 2 diabetes, coronary heart diseases, stroke, and hypertension) at baseline. Smoking status was categorized into former, current, and never smokers, with age at smoking initiation and smoking cessation as a proxy for current and former smokers. The multi-state model was performed to evaluate the association between cigarette smoking, smoking cessation and CMM.ResultsDuring a median follow-up of 13.2 years, 59,193 participants developed first cardiometabolic disease (FCMD), 14,090 further developed CMM, and 16,487 died. Compared to former smokers, current smokers had higher risk at all transitions, with hazard ratio (95% confidence interval) = 1.59 (1.55 ∼ 1.63) vs. 1.18 (1.16 ∼ 1.21) (P = 1.48 × 10- 118) from health to FCMD, 1.40 (1.33 ∼ 1.47) vs. 1.09 (1.05 ∼ 1.14) (P = 1.50 × 10- 18) from FCMD to CMM, and 2.87 (2.72 ∼ 3.03) vs. 1.38 (1.32 ∼ 1.45) (P < 0.001) from health, 2.16 (1.98 ∼ 2.35) vs. 1.25 (1.16 ∼ 1.34) (P = 1.18 × 10- 46) from FCMD, 2.02 (1.79 ∼ 2.28) vs. 1.22 (1.09 ∼ 1.35) (P = 3.93 × 10- 17) from CMM to death; whereas quitting smoking reduced the risk attributed to cigarette smoking by approximately 76.5% across all transitions. Reduced risks of smoking cessation were also identified when age at quitting smoking was used as a proxy for former smokers.ConclusionsCigarette smoking was associated with a higher risk of CMM across all transitions; however, smoking cessation, especially before the age of 35, was associated with a significant decrease in CMM risk attributed to cigarette smoking.

Project description:IntroductionTo examine the associations between baseline receipt of cigarette and non-cigarette tobacco discounts or coupons and smoking cessation at follow-up among US adult cigarette smokers with the intention to quit at baseline.Aims and methodsData were from the Population Assessment of Tobacco and Health (PATH) study wave 3 (October 2015-October 2016), wave 4 (December 2016-January 2018), and wave 5 (December 2018-November 2019) surveys. Two separate sets of analyses were conducted using wave 3-4 data (N = 3707) and wave 4-5 data (N = 6251). Specifically, wave 4 was used as the 1-year follow-up of wave 3 to examine the short-term association, and wave 5 was used as the 2-year follow-up of wave 4 to examine the longer-term association. Study population were current established cigarette smokers with the intention to quit (within 1 year for wave 3-4 data) at baseline. Exposure was self-reported past 12-month receipt of discounts or coupons for cigarettes and non-cigarette tobacco products at baseline, and outcome was self-reported completely quitting cigarette smoking at follow-up. Baseline single-wave weights were applied, and multivariate logistic regressions were used to estimate the adjusted associations.ResultsParticipants who received cigarette discounts or coupons at baseline were less likely to quit completely for both 1-year follow-up (aOR = 0.66, 95% CI: 0.48 to 0.90) and 2-year follow-up (aOR = 0.74, 95% CI: 0.61 to 0.90). Baseline receipt of discounts or coupons for non-cigarette tobacco products were not consistently associated with cigarette smoking cessation at follow-up.ConclusionsReceipt of cigarette discounts or coupons was associated with a reduced likelihood of successful quitting among cigarette smokers with intention to quit. Policies restricting cigarette coupons may help them quit completely.ImplicationsThis study found that among baseline current established cigarette smokers with intention to quit in the United States, baseline receipt of cigarette discounts or coupons was negatively associated with cigarette smoking cessation for both 1-year follow-up and 2-year follow-up. Baseline receipt of discounts or coupons for e-cigarettes, cigars, and other tobacco products were not consistently significantly associated with cigarette smoking cessation at follow-up. Our study results indicated that policies restricting cigarette coupons may help increase the likelihood of successful smoking cessation for smokers with intention to quit.
