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) coincided with the arrival of certain moviegoers and left residual … 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 Score (PCS)… After additional adjustment for BDI score, the observed … 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 22.6 to 24.7) for women who adopted no low risk … 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 differed by sex. The clustering of physical inactivity and low … 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 a parallel nonrandomized preference cohort and blinded endpoint of smokers … 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 (OR, 1.85; 95% CI, 1.10-3.11; P = .04; I2 = 0%). Evaluations of ever … 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 group, the intervention group had statistically higher biochemically validated abstinence … 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 (CI) 1.67–3.08, p < 0.001) and depression (OR 1.99, 95% … Continue reading Evidence for causal effects of lifetime #smoking on risk for #depression and #schizophrenia: a Mendelian randomisation study

Associations Between #vascular Risk Across Adulthood and #Brain Pathology in Late Life Evidence From a British Birth Cohort

Office-based Framingham Heart study–cardiovascular risk scores (FHS-CVS) were derived at ages 36, 53, and 69 years using systolic blood pressure, antihypertensive medication usage, smoking, diabetic status, and body mass index. Analysis models adjusted for age at imaging, sex, APOE genotype, socioeconomic position, and, where appropriate, total intracranial volume. ..At all points, these scores were associated with smaller whole-brain volumes (36 years: β coefficient per 1% … Continue reading Associations Between #vascular Risk Across Adulthood and #Brain Pathology in Late Life Evidence From a British Birth Cohort

Long-Term Evolution of Premature #Coronary Artery Disease

They were age 40.1 ± 5.7 years, mainly men, smokers, with a family history of CAD or hypercholesterolemia. At baseline presentation, 91.2% underwent coronary revascularization, predominantly for acute MI (78.8%). Over a follow-up of 20 years, one-third (n = 264) of patients presented with a total of 399 ischemic events, and 36% had at least a second recurrent event. MI was the most frequent first … Continue reading Long-Term Evolution of Premature #Coronary Artery Disease

Childhood Tobacco Smoke Exposure and Risk of Atrial #Fibrillation in Adulthood

Of 2,816 Offspring cohort participants with at least 1 parent in the Original cohort, 82% were exposed to parental smoking. For every pack/day increase in parental smoking, there was an 18% increase in offspring AF incidence (adjusted hazard ratio [HR]: 1.18; 95% confidence interval [CI]: 1.00 to 1.39; p = 0.04). Additionally, parental smoking was a risk factor for offspring smoking (adjusted odds ratio [OR]: … Continue reading Childhood Tobacco Smoke Exposure and Risk of Atrial #Fibrillation in Adulthood
