There has been limited evidence for the association between chronic obstructive pulmonary disease (COPD) and the incidence of lung cancer among never smokers. We aimed to estimate the risk of lung cancer incidence in never smokers with COPD, and to compare it with the risk associated with smoking. This cohort study involved 338 548 subjects, 40… Continue reading Chronic #obstructive pulmonary disease and lung cancer incidence in never smokers: a cohort study

Human transport of thirdhand tobacco #smoke: A prominent source of hazardous air pollutants into indoor nonsmoking environments
The contamination of indoor nonsmoking environments with thirdhand smoke (THS) is an important, poorly understood public health concern. Real-time THS off-gassing from smokers into a nonsmoking movie theater was observed with online and offline high-resolution mass spectrometry. Prominent emission events of THS tracers (e.g., 2,5-dimethylfuran, 2-methylfuran, and acetonitrile) and other tobacco-related volatile organic compounds (VOCs)… Continue reading Human transport of thirdhand tobacco #smoke: A prominent source of hazardous air pollutants into indoor nonsmoking environments
#Tobacco smoking and health-related quality of life among university students: Mediating effect of #depression
The aim of this study was to assess the association between cigarette smoking and health-related quality of life (HRQoL) among students in two different universities, and the potential mediating effect of depression. ..In both populations, after adjustment for socio-demographic, behavioral and health factors, smoking was associated with poorer Mental Composite Score (MCS) and Physical Composite… Continue reading #Tobacco smoking and health-related quality of life among university students: Mediating effect of #depression
Healthy #lifestyle and life #expectancy free of cancer, cardiovascular disease, and type 2 diabetes: prospective cohort study
..Five low risk lifestyle factors: never smoking, body mass index 18.5-24.9, moderate to vigorous physical activity (≥30 minutes/day), moderate alcohol intake (women: 5-15 g/day; men 5-30 g/day), and a higher diet quality score (upper 40%). .. The life expectancy free of diabetes, cardiovascular diseases, and cancer at age 50 was 23.7 years (95% confidence interval… Continue reading Healthy #lifestyle and life #expectancy free of cancer, cardiovascular disease, and type 2 diabetes: prospective cohort study
Clustering of #lifestyle risk factors for non-communicable diseases in 304,779 #adolescents from 89 countries: A global perspective
The precursors of non-communicable diseases (NCDs) are often manifested during childhood and adolescence with little knowledge about co-occurrence of their related lifestyle risk factors. .. ..Adolescents aged 16–17 years, compared to those aged 11–13 years, had higher odds (OR 1.33; 95% CI 1.31–1.36) of reporting ≥3 risk factors. Risk factors clustered in multiple combinations and… Continue reading Clustering of #lifestyle risk factors for non-communicable diseases in 304,779 #adolescents from 89 countries: A global perspective
Cardiovascular Effects of Switching From Tobacco #Cigarettes to Electronic Cigarettes
E-cigarette (EC) use is increasing exponentially worldwide. The early cardiovascular effects of switching from tobacco cigarettes (TC) to EC in chronic smokers is unknown. Meta-analysis of flow-mediated dilation (FMD) studies indicate 13% lower pooled, adjusted relative risks of cardiovascular events with every 1% improvement in FMD. ..The authors conducted a prospective, randomized control trial with… Continue reading Cardiovascular Effects of Switching From Tobacco #Cigarettes to Electronic Cigarettes
Association Between #Marijuana Use and Risk of #Cancer A Systematic Review and Meta-analysis
.. In pooled analysis of case-control studies, ever use of marijuana was not associated with head and neck squamous cell carcinoma or oral cancer. In pooled analysis of 3 case-control studies, more than 10 years of marijuana use (joint-years not reported) was associated with TGCT (OR, 1.36; 95% CI, 1.03-1.81; P = .03; I2 = 0%) and nonseminoma TGCT… Continue reading Association Between #Marijuana Use and Risk of #Cancer A Systematic Review and Meta-analysis
Effectiveness of a Brief Self-determination Theory–Based Smoking Cessation Intervention for Smokers at Emergency Departments in Hong Kong
Clinicians have an opportunity to provide #smoking cessation interventions to smokers who present to emergency departments (EDs). The effectiveness of a brief intervention based on self-determination theory for smoking cessation is uncertain. ..The intervention group received brief advice (about 1 minute) and could choose their own quit schedules (immediate or progressive) ..Compared with the control… Continue reading Effectiveness of a Brief Self-determination Theory–Based Smoking Cessation Intervention for Smokers at Emergency Departments in Hong Kong
Evidence for causal effects of lifetime #smoking on risk for #depression and #schizophrenia: a Mendelian randomisation study
Smoking prevalence is higher amongst individuals with schizophrenia and depression compared with the general population. Mendelian randomisation (MR) can examine whether this association is causal using genetic variants identified in genome-wide association studies (GWAS). There was strong evidence to suggest smoking is a risk factor for both schizophrenia (odds ratio (OR) 2.27, 95% confidence interval… Continue reading Evidence for causal effects of lifetime #smoking on risk for #depression and #schizophrenia: a Mendelian randomisation study
