Stress-related expectations about smoking cessation and future quit attempts and abstinence - a prospective study in daily smokers who wish to quit.

Smokers who wish to quit may refrain from doing so if they expect to experience more stress after haven given up. We test if stress-related expectations about smoking cessation are associated with quit attempts and abstinence among smokers who are motivated to quit. The study included 1809 daily smokers in Denmark in 2011-2013.

Does High Tobacco Consumption Cause Psychological Distress? A Mendelian Randomization Study.

Background: Increasing evidence suggests that smoking influences mental health negatively. This study investigated whether high tobacco consumption is causally related to psychological distress in a Mendelian randomization design, using a variant in the nicotine acetylcholine receptor gene CHRNA3-known to influence individual tobacco consumption-as instrumental variable for tobacco consumption.

Methods: Data from 90 108 participants in the Copenhagen General Population Study was used.

The Systematic Development of an Internet-Based Smoking Cessation Intervention for Adults.

Objectives The objective of this project was to determine whether intervention mapping is a suitable strategy for developing an Internet- and text message-based smoking cessation intervention. Method We used the Intervention Mapping framework for planning health promotion programs. After a needs assessment, we identified important changeable determinants of cessation behavior, specified objectives for the intervention, selected theoretical methods for meeting our objectives, and operationalized change methods into practical intervention strategies.

The effectiveness of telephone counselling and internet- and text-message-based support for smoking cessation: results from a randomized controlled trial.

Aim: To compare the effectiveness of proactive telephone counselling, reactive telephone counselling and an internet- and text-message-based intervention with a self-help booklet for smoking cessation.

Design: A randomized controlled trial with equal allocation to four conditions: (1) proactive telephone counselling (n = 452), (2) reactive telephone counselling (n = 453), (3) internet- and text-message-based intervention (n = 453) and (4) self-help booklet (control) (n = 452).

Setting: Denmark.

What characterises smokers who quit without using help? A study of users and non-users of cessation support among successful ex-smokers.

Background: A variety of smoking cessation aids are available; however, the majority of smokers quit unaided. We know little of the differences between users and non-users of cessation support.

Methods: A cross-sectional study based on the Danish Health Examination Survey (DANHES) conducted in 2007-2008.

Preoperative smoking status and postoperative complications: a systematic review and meta-analysis.

Objective: To systematically review and summarize the evidence of an association between preoperative smoking status and postoperative complications elaborated on complication type.

Background: The conclusions of studies examining the association between preoperative smoking and postoperative complications are inconsistent, thus there is a need for a review and meta-analysis to summarize the existing evidence.

Methods: A systematic review and meta-analysis based on a search in MEDLINE, EMBASE, CINAHL, and PsycINFO.

Preoperative alcohol consumption and postoperative complications: a systematic review and meta-analysis.

Objective: To systematically review and summarize the evidence of the association between preoperative alcohol consumption and postoperative complications elaborated on complication type.

Background: Conclusions in studies on preoperative alcohol consumption and postoperative complications have been inconsistent.

Methods: A systematic review and meta-analysis based on a search in MEDLINE, EMBASE, CINAHL, and PsycINFO citations.

"After all--it doesn't kill you to quit smoking": an explorative analysis of the blog in a smoking cessation intervention.

Background: A growing body of literature demonstrates internet-based smoking cessation interventions as a promising aid in helping people quit smoking. However, the underlying mechanisms of how these interventions influence the cessation process are still relatively unknown. Several studies have indicated blogging as a potential source in providing social support to users of internet-based smoking cessation interventions and thereby enhance their change of succeeding in quitting.

Binge drinking, drinking frequency, and risk of ischaemic heart disease: a population-based cohort study.

Introduction: Light-to-moderate alcohol drinking is associated with a decreased risk of ischaemic heart disease (IHD). However, drinking heavily and in binges has been suggested to increase IHD risk. This complexity makes the issue of binge drinking within the light-to-moderate alcohol range an important area for further investigation.

Maternal alcohol drinking pattern during pregnancy and the risk for an offspring with an isolated congenital heart defect and in particular a ventricular septal defect or an atrial septal defect.

Background: This cohort study examines the possible association between maternal alcohol intake, including binge drinking, during pregnancy, and the subsequent risk of having a child with an isolated congenital heart defect and, more specifically, with the isolated form of ventricular septal defect (VSD) or of an atrial septal defect (ASD).

Methods: Participants were 80,346 pregnant women who were enrolled into the Danish National Birth Cohort in 1996-2002 and gave birth to a live-born singleton without any chromosome anomalies. Twice during pregnancy these women were asked about their intake of alcohol.
