Association between alcohol, socioeconomic position and labour market participation: A prospective cohort study of transitions between work and unemployment.

Aims: This study aimed to test the hypothesis that heavy alcohol consumption and problem drinking is associated with a higher risk of becoming unemployed and a lower chance of entering the job market across socioeconomic positions. Methods: A sample of 84,474 men and women aged 18-60 years from the Danish National Health Survey 2010 participated in the study. Information on alcohol consumption and problem drinking was obtained by questionnaire. The primary outcomes were becoming unemployed and entering the job market. The follow-up period was five years. Information on labour market transitions and socioeconomic position (educational level) was obtained through nationwide registers. Multiplicative analyses were performed. Results: Heavy alcohol consumption and problem drinking were associated with a higher risk of unemployment among low-educated (hazard ratio (HR)=1.5; 95% confidence interval (CI) 1.3-1.9) and medium-educated (HR=1.3; 95% CI 1.1-1.5) individuals in comparison to individuals with a similar educational level drinking one to seven drinks per week. Excessive alcohol consumption and problem drinking were associated with a lower chance of entering the job market for individuals with a medium or high level of education: medium-educated individuals drinking >28 drinks per week had a HR of 0.82 (95% CI 0.69-0.98) when compared to medium-educated individuals drinking one to seven drinks per week. The corresponding HR among high-educated individuals was 0.71 (95% CI 0.49-1.0). Conclusions: Heavy alcohol consumption and problem drinking are associated with a higher risk of unemployment in some social strata, whereas excessive alcohol consumption and problem drinking are associated with a lower chance of entering the job market in other social strata.

BMI and Labor Market Participation: A Cohort Study of Transitions Between Work, Unemployment, and Sickness Absence.

OBJECTIVE: This study aimed to test the hypotheses that individuals with obesity are at higher risk of unemployment and sickness absence and have a lower chance of getting employed compared with individuals with normal weight. METHODS: Data on weight and height were collected at baseline from 87,796 participants in the Danish National Health Survey 2010. Participants were then followed in national registers for 5 years. Outcome measures were transitions from employment to unemployment and sickness absence and the transitions from unemployment or sickness absence to employment. Data were analyzed by Cox proportional hazards models adjusted for potential confounders. RESULTS: Hazard ratios for unemployment were 1.18 (95% CI: 1.10-1.26) for individuals with obesity and 1.27 (95% CI: 1.14-1.41) for individuals with severe obesity compared with individuals with normal weight. Participants with obesity also had a higher risk of sickness absence. Additionally, participants with obesity who were unemployed at baseline had a lower chance of becoming employed compared with participants with normal weight. CONCLUSIONS: Obesity was associated with a higher risk of unemployment and sickness absence compared with individuals with normal weight. Additionally, obesity was associated with a lower chance of employment.

Trends in smoking and smokeless tobacco use among Danish Adolescents, 1997-2014.

INTRODUCTION: High rates of smoking among adolescents remain a public health concern. This study investigates smoking behavior and use of smokeless tobacco among Danish high-school students and assesses how smoking and use of smokeless tobacco cluster in schools and school classes. We estimate the trend in cigarette smoking from 1997 to 2014. METHODS: We used data on 70 243 students, from 3 214 school classes in 119 high schools, who participated in the Danish National Youth Study from 2014. We had information on 87% of all Danish high schools and 85% of eligible students. We also used data from 1997 on 26 644 high-school students from a similar data set to assess the chronological trend in smoking. We calculated prevalences and intraclass correlation coefficients (ICCs) to estimate between-school and between-school class clustering in smoking and use of smokeless tobacco. RESULTS: In all, 14% of boys and 11% of girls were daily smokers. A large fraction of the variation in smoking and the use of smokeless tobacco was attributable to the school and school-class level (ICC of 0.19, 0.12, 0.16 and 0.27, for daily smoking, waterpipe smoking, use of electronic cigarettes and snuff/chewing tobacco, respectively). Daily smoking decreased from 15% in 1997 to 12% in 2014, while more students were occasional smokers in 2014 than in 1997 (30% vs 18%). CONCLUSIONS: The prevalence of smoking was high among Danish high-school students and had changed little since 1997. The school and class environment accounted for a large part of the variation in smoking behavior.
