RESUMEN
AIMS: Adapting interventions with an existing evidence base offers a more efficient approach than development of a new intervention. The aim of this study was to describe the process of adapting a home-based cardiac rehabilitation (CR) programme (REACH-HF) intervention originally developed in the United Kingdom for people with heart failure (HF) to the Danish health system - the 'DK:REACH-HF' programme. METHODS AND RESULTS: We followed methodological framework for the conduct and reporting of studies adapting interventions, utilizing documentary analysis, qualitative interviews, stakeholder consultations, and mapping of the Danish policy context. Our study found broad support for the REACH-HF intervention as an alternative to existing centre-based CR. We also identified three key areas of adaptation for the Danish context. First, reduce the word-count of the intervention's resources by linking to existing publicly available CR materials. Second, whilst retaining REACH-HF core components, adapt its content and delivery to reflect differences between Denmark and United Kingdom. Thirdly, to develop a digital version of the intervention. CONCLUSION: Using an evidence-based approach, we successfully adapted the REACH-HF intervention to the context of the Danish healthcare setting, maintaining core components of the original intervention, and developing both a paper based and digital version of the programme material. To inform scaled national implementation of the DK:REACH-HF programme, we seek to undertake a pilot study to test the adapted intervention materials feasibility and acceptability to healthcare practitioners, patients, and their caregivers and confirm the positive impact on the outcomes of HF patients and caregivers.
RESUMEN
AIM: The aim was to identify maternal and paternal socioeconomic and demographic characteristics for non-initiation and non-completion of the human papillomavirus (HPV) vaccination among Danish girls including time-trends. METHODS: This nationwide register-based cohort study included all girls residing in Denmark who were offered free-of-charge HPV vaccination as a part of the childhood vaccination program between 2009 and 2018 (birth cohorts 1996-2005). The study samples included 296,461 daughter-mother dyads and 291,025 daughter-father dyads. Data from the Danish Vaccination Register were linked with socioeconomic and demographic data from Statistics Denmark. HPV vaccination status was classified as 'non-initiation' for girls who received no HPV vaccine and as 'non-completion' for girls who initiated the HPV vaccination program but did not receive all the scheduled HPV vaccines. Data were analyzed using logistic regression models. RESULTS: Non-initiation of HPV vaccination was 13.7%, and non-completion was 24.2% among girls who initiated the HPV vaccination program. Girls of parents who were descendants of immigrants (adjusted odds ratio: 1.50; 95% confidence interval: 1.35-1.68), were at least 35-years old at time of birth, had basic or no education, had a low income, were not in the labor market, and were unmarried had the highest non-initiation and non-completion odds. The associations between socioeconomic and demographic characteristics and HPV vaccination uptake were similar for mothers and fathers. CONCLUSIONS: Despite free-of-charge availability to HPV vaccination in Denmark, we found disparities in non-initiation and non-completion of HPV vaccination among Danish girls by both mothers' and fathers' socioeconomic and demographic characteristics.
RESUMEN
Background: Alcohol is a leading risk factor to adolescent health. However, it is unclear how associations between alcohol intake and injuries are shaped. We investigated the dose-response relationship between alcohol intake and risk of hospital contacts due to alcohol and unintentional injuries in adolescents. Methods: We conducted a prospective cohort study including 71,025 Danish students aged 15-24 years, followed up for five years from 2014 to 2019. The main outcome measures were hospital contacts due to alcohol and unintentional injuries (all injuries and head injuries), obtained from hospital registers. Findings: Approximately 90% of males and females reported drinking alcohol, and the median intake among those was 11 drinks/week in males and 8 drinks/week in females. During five years of follow-up, 1.3% had an alcohol-attributable hospital contact, the majority of which were due to acute intoxication (70%). Alcohol-attributable hospital contacts were equally frequent in males and females and between age groups (15-17-year-olds vs 18-24-year-olds). Compared with never drinking, the adjusted incidence rate ratios for weekly intake of <7, 7-13, 14-20, 21-27, and >27 drinks/week were 1.70 (95% confidence interval 1.23-2.34), 1.77 (1.27-2.46), 1.91 (1.35-2.70), 2.34 (1.59-3.46), and 3.25 (2.27-4.64) for having an alcohol-attributable hospital contact within five years of follow-up. Restricting follow-up to one year more than doubled risk estimates. During the five years of follow-up, 27% incurred an unintentional injury. The most frequent types of injury were to the wrist or hand (27.6%), ankle or foot (25.2%), or head (12.4%). Injuries were more frequent among males (first-time incidence rate 110 per 1000 person-years) compared to females (82 per 1000 person-years), with no differences between age groups. Compared with never drinking, the adjusted incidence rate ratios for weekly intake of <7, 7-13, 14-20, 21-27, and >27 drinks were 1.09 (1.03-1.15), 1.14 (1.07-1.20), 1.25 (1.17-1.33), 1.38 (1.28-1.49), and 1.58 (1.47-1.69) for having a hospital contact for any type of unintentional injury within five years of follow-up. Results for the one-year follow-up period were comparable. Separate analysis for head injuries showed similar results as the analysis on all injuries. Results were generally similar in males and females. Interpretation: Adolescents' drinking is associated with a higher risk of acute harm in terms of hospital contacts due to alcohol and unintentional injuries in a dose-response relationship. Thus, increased risk was apparent in those with low alcohol intake, suggesting a need for awareness of and initiatives to prevent youth drinking. Furthermore, initiatives should include a strengthened focus on people younger than 18 years. Funding: This study was funded by the Tryg Foundation (ID: 153539) and The Helse Foundation (21-B-0359).
RESUMEN
INTRODUCTION: The epidemic increase in obesity is well documented and of intensive public health interest. Attention has almost entirely focused on a dichotomous measure of obesity such as how the prevalence of BMI ≥ 30 kg/m2 has changed over time. Less consideration has been given to how the general distribution of BMI has evolved. METHODS: We used data from the National Health and Morbidity Surveys, which are surveys of the adult Danish population (16 years or above) conducted in 1987, 2000, 2005, 2010, 2013, 2017 and 2021. Participants reported height and weight from which BMI was calculated following correction for systematic bias in self-reported data and non-response. RESULTS: The prevalence of obesity in Denmark increased from 6.1% in 1987 to 18.4% in 2021. A right shift in BMI distribution was observed with positive linear slopes for high and low BMI percentiles and for all socioeconomic groups, although with steeper slopes for high BMI percentiles and for short education. CONCLUSIONS: The right shift in the distribution curve of BMI from 1987 to 2021 with gradually higher values in all BMI percentiles and in all socioeconomic strata show that the increasing obesity prevalence may, to some extent, be attributed to a generally higher BMI in the entire Danish population. FUNDING: None. TRIAL REGISTRATION: Not relevant.

Background: Evidence shows that similar levels of alcohol consumption lead to greater harm in adults with low socioeconomic position (SEP) compared to high SEP. We investigated if SEP is associated with alcohol-related hospital contacts in adolescents, and whether differences in risk can be explained by differences in levels of alcohol consumption, drinking pattern, and substance use. Methods: This is a prospective cohort study of 68,299 participants aged 15-19 years old from the Danish National Youth Cohort 2014. SEP was operationalised as parent educational level, family income and perceived financial strain in the family. Data were linked to national registers and participants were followed up for five years from 2014 to 2019. Outcomes were hospital contacts due to alcohol. Multilevel Poisson regression was used to estimate incidence rates (IR) and incidence rate ratios (IRR). Findings: During 280,010 person years of follow-up, 872 participants had an alcohol-attributable hospital contact; intoxications (n = 778, 89%) were the most common diagnosis. Low as compared to high SEP was associated with higher IRR of alcohol-attributable hospital contacts for all three SEP measures. The adjusted IRR of harm was 1.73 (95% CI: 1.29-2.33) for elementary school as the highest parent education compared to longer parent education and 1.57 (95% CI: 1.30-1.89) for family financial strain compared to those without financial strain. Adjustment for weekly alcohol intake, drinking pattern and substance use did not substantially change results. Cubic spline analysis of the association between family income and alcohol-attributable hospital contacts revealed a dose-response relationship with decreasing risk of alcohol-related harm with higher income. Interpretation: Our findings suggested that alcohol-related harm is more common in socioeconomically disadvantaged adolescents despite similar levels of alcohol consumption, regardless of differences in drinking pattern or substance use. Future preventive strategies should prioritise young adolescents, including those who are most disadvantaged. Funding: Tryg Foundation (ID: 153539).
RESUMEN
BACKGROUND: National comprehensive smoke-free legislation has been found to decrease the incidence of several smoking-related diseases. In 2007, Denmark introduced a national smoking ban, which banned smoking indoor in workplaces and public places, although only partial restrictions were applied in certain settings. We examined the impact of the smoking ban on smoking-related diseases and whether this differed across socioeconomic groups. METHODS: Interrupted time series analyses of nationwide register data were performed using Poisson regression models to examine the differential impact of the smoking ban on monthly incidence rates of acute myocardial infarction, chronic obstructive pulmonary disease, and smoking-related cancers from 2002 to 2015. Immediate changes in incidence rates after the smoking ban and long-term changes in disease trends were estimated by comparing data from the pre- and post-ban period. Models were stratified by socioeconomic position. RESULTS: Overall, we found neither immediate changes in rates of acute myocardial infarction, chronic obstructive pulmonary disease, and smoking-related cancers following the smoking ban nor long-term post-ban changes in disease trends as compared to before the ban. Results did not differ across socioeconomic groups. A pronounced socioeconomic gradient in incidence rates was observed for all outcomes both before and after the smoking ban. CONCLUSION: The national smoking ban was not associated with a lower incidence of smoking-related diseases in the post-ban period compared to pre-ban levels and no differences between socioeconomic groups were observed. Future tobacco control in Denmark should consider which measures most effectively target the low socioeconomic groups to decrease the current strong socioeconomic inequality in health.

AIM: The aim of this study was to investigate changes in the prevalence of loneliness in Denmark from 2000 to 2021 by conducting age-period-cohort analysis. METHODS: Our study was based on a sample (N=83,437; age: ⩾16 years) of the Danish Health and Morbidity Surveys conducted in Denmark in 2000, 2005, 2010, 2013, 2017 and 2021. We used logistic regression models by gender to estimate the age-period-cohort effects, with loneliness as the dependent variable and age, survey year and birth cohort as independent variables, mutually adjusted. RESULTS: The prevalence of adult loneliness increased by each survey year over the entire period (from 13.2% in 2000 to 27.4% in 2021 among men and from 18.8% to 33.7% among women). Overall, a U-shaped curve, for the prevalence of loneliness among different age groups, was observed, which was most pronounced among women. The greatest increase in the prevalence of loneliness from 2000 to 2021 was observed among the youngest age group (16-24 years), with 28.4 and 30.7 percentage points for men and women. No significant cohort effect was observed. CONCLUSIONS: The observed increase in loneliness prevalence from 2000 to 2021 was driven by period and age effects rather than cohort effects. It should be noted that data from 2021 were collected during a national lockdown due to an outbreak of COVID-19, which could explain part of the large increase in loneliness from 2017 to 2021.
RESUMEN
Milk formation in the breast during breastfeeding is a complex hormonally regulated process, potentially sensitive to the effects of endocrine-disrupting chemical exposures. The environmental chemicals, per- and polyfluoroalkyl substances (PFAS) are known endocrine disruptors. PFAS exposure have been associated with insufficient mammary gland development in mice and reduced breastfeeding duration in humans. The aim of this review was to gather the epidemiological evidence on the association between PFAS exposure and breastfeeding duration. Using PubMed and Embase, we performed a systematic literature search (on 23 January 2023) to identify epidemiological studies examining the association between maternal PFAS exposure and breastfeeding duration. Animal studies, reviews, and non-English studies were excluded. The risk of bias was assessed using the risk of bias in non-randomized studies of exposures tool. Estimates describing the association between PFAS exposure and the duration of breastfeeding were identified, and the data were synthesized separately for each type of PFAS and for the duration of exclusive and total breastfeeding. Six studies with between 336 and 2374 participants each were identified. PFAS exposure was assessed in serum samples (five studies) or based on residential address (one study). Five out of six studies found shorter total duration of breastfeeding with higher PFAS exposure. The most consistent associations were seen for perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), and perfluorononanoic acid (PFNA). The finding of a potential causal association between PFAS exposure and breastfeeding duration is in agreement with findings from experimental studies.
RESUMEN
Background: Adolescents and young adults aged 15-24 years are disproportionately affected by unnatural deaths, including accidents, suicide and interpersonal violence for which alcohol is a leading risk factor. We aimed to explore the extent of and circumstances surrounding alcohol-related deaths in young people aged 15-24 years and whether socioeconomic background and ethnicity differ in those who died due to alcohol-related causes as compared to the background population. Methods: All deaths of 15-24-year-olds occurring in Denmark from 2010 to 2019 were investigated. We manually reviewed death certificates containing information on circumstances, results from autopsies and blood tests, and statements from witnesses. Relevant information published in the media (most often newspaper articles) was included. Our main outcome measures were alcohol-related death and manner of death (accidents (transport accidents, drownings, falls, poisonings), suicide and violence). Further, we designed a population-based case-control study including 10 age- and sex-matched controls per case to test whether there was a socioeconomic gradient in alcohol-related deaths. We used parents' educational level and employment status to define socioeconomic position. Immigration status was used to assess ethnicity. Findings: Over the 10-year period, 1783 deaths occurred among 15-24-year-olds. Of those, 1067 (60%) were due to unnatural causes, corresponding to a mortality rate of 14.8 (95% confidence interval: 13.9-15.7) per 100,000. Twelve percent of unnatural deaths (n = 125) were alcohol related, corresponding to a rate of 1.7 (1.4-2.0) per 100,000, and were higher in males (2.9 [2.3-3.4]) than in females (0.6 [0.3-0.8]); thus, males accounted for 105 (84%) of alcohol-related deaths. The majority of alcohol-related deaths occurred on Fridays, Saturdays and Sundays (n = 77, 62%). Accidents accounted for 82% (n = 102) of alcohol-related deaths, followed by suicide (n = 19, 15%) and interpersonal violence (n = 4, 3%). Of all fatal accidents, 102 of 636 (16%) were alcohol related. Of all deaths caused by drownings and falls, 14 of 26 (54%) and 10 of 25 (40%), respectively, were alcohol related. Alcohol-related drownings most often occurred while the deceased was alone, whereas alcohol-related falls most often occurred in relation to parties, involving falls from a window or balcony. Those who died from alcohol-related causes more often had parents with a short education or who were unemployed, as compared to the general population. For example, odds ratios were 3.9 (2.2-7.0) and 1.8 (1.2-2.9) for having parents with short and medium as compared to long educations. The odds ratio for being of Danish origin was 4.0 (1.7-9.5) compared to being first- or second-generation immigrants. Interpretation: In 15-24-year-olds, alcohol-related deaths accounted for a substantial proportion of all unnatural deaths. There was substantial socioeconomic inequality in alcohol-related deaths, as has repeatedly been shown for chronic alcohol-related mortality in older adults. Funding: Trygfonden.
RESUMEN
BACKGROUND: During the last decades, the prevalence of obesity [body mass index (BMI): weight/height2), ≥30.00 kg/m2] among adults has increased considerably. We examined whether this increase in a high-income, welfare state, like Denmark was driven by age, period or cohort effects, which would inform preventive strategies aiming at reducing the prevalence. METHODS: We used data from the National Representative Health and Morbidity Studies, which are representative surveys of the Danish adult population (age 16 years and above), conducted in 1987, 1994, 2000, 2005, 2010, 2013, 2017 and 2021 (N = 91â684). Participants reported height and weight, from which BMI was calculated after correction for systematic bias in self-reported data and non-response. Age, survey year and birth cohorts were mutually adjusted and adjusted for sex in generalized linear models. RESULTS: The obesity prevalence increased from 6.1% in 1987 to 18.4% in 2021, similarly in men (18.8%) and women (18.0%) and in all age groups. Age had an inverted u-shaped effect on the prevalence. Compared with individuals aged 16-24 years, the highest rate of obesity was seen for the age group 55-64 years [rate ratio 3.27, 95% confidence interval (CI): 2.58; 4.14]. The increasing rate for each recent survey year over time was compatible with a period effect without any birth cohort effects. The rate for obesity in 2021 was 4.16 in 1987 vs. 1987 (95% CI: 3.10; 5.59). CONCLUSIONS: Obesity prevalence in Denmark increased steadily during the period 1987 through 2021, primarily driven by secular changes over time across all ages and birth cohorts.

INTRODUCTION: The aim of the study was to test the hypothesis that young people with perceived parental alcohol problems have higher dropout rates in high school and lower grade point average (GPA) at graduation compared to young people without perceived parental alcohol problems. METHODS: Data come from Danish National Youth Study 2014 (n = 62,171), merged with register-data on later dropout of high school and GPA. Multilevel Poisson regression models of incidence rates of dropout and multilevel linear models of GPA were used to assess the association with perceived parental alcohol problems. RESULTS: A total of 6.6% of the students perceived their parent(s) to have alcohol problems. Young people with perceived parental alcohol problems had higher dropout rate (girls incidence rate ratio 1.83; 95% confidence interval [1.62-2.06]); boys (incidence rate ratio 1.38; 95% confidence interval [1.17-1.64]) and lower grades (GPA: -0.24; 95% confidence interval [-0.32; -0.17]) compared to those without. There was no statistically significant difference between mother's and fathers' alcohol problems in the associations with dropout and GPA. DISCUSSION AND CONCLUSIONS: Perceived parental alcohol problems were associated with higher incidence rate ratio of dropout and lower grades within all categories of the socioeconomic factors. Our results show that young people with perceived parental alcohol problems have higher high school dropout rates and lower grades compared to those without perceived parental alcohol problems across gender and socioeconomic position. The results call for evidence-based interventions to support young people with parental alcohol problems in the educational system.

AIM: To examine whether smokers are at higher risk of unemployment and sickness absence and have a lower chance of getting employed compared to never smokers. METHODS: The study sample in this prospective register-based cohort study consisted of 87,830 men and women between 18 and 60 years of age from the Danish National Health Survey 2010. Assessment of smoking status was obtained at baseline and the participants were followed in the Danish register-based evaluation of marginalisation database from 2010 to 2015. Data were analysed by Cox proportional hazards. RESULTS: The median age was 44.5 years and 47.3% were men. At baseline, 88.8% were categorised as working, 7.7% as unemployed and 3.5% as being on sickness absence. At the 5-year follow-up, hazard ratios for transitions from work to unemployment were 1.31 (95% confidence interval (CI) 1.22-1.40; P<0.001) for current smokers (<15/day) and 1.52 (95% CI 1.43-1.62; P<0.001) for current heavy smokers (⩾15/day), compared to never smokers. Hazard ratios for transitions from work to sickness absence were 1.31 (95% CI 1.24-1.38; P<0.001) for current smokers (<15/day) and 1.64 (95% CI 1.56-1.71; P<0.001) for current heavy smokers (⩾15/day). Current heavy smokers (⩾15/day) also had a lower chance of becoming re-employed with a hazard ratio of 0.81 (95% CI 0.75-0.88; P<0.001) compared to never smokers.Smoking was associated with a higher risk of unemployment and sickness absence, and a lower chance of becoming employed. More focus on smoking prevention and smoking cessation could therefore be implemented in relation to job seeking and sickness absence.

AIMS: To analyse whether parental alcohol norms were associated with the alcohol intake of high school students and whether this association persisted across different levels of alcohol intake in school and trustful communication with parents. METHODS: This was a cross-sectional study among 70,544 high school students (mean age 18 years) participating in the Danish National Youth Study 2014. We examined the associations between parental alcohol norms and individual alcohol intake as the number of drinks at the most recent school party and the frequency of binge drinking in the last 30 days using negative binomial regression. We then performed joint analyses of parental alcohol norms and alcohol intake at school level, and parental alcohol norms and trustful communication with parents. RESULTS: The mean intake of alcohol at the most recent school party was 9.9 units of alcohol for boys and 7.6 units of alcohol for girls. A total of 36.2% of boys and 24.7% of girls were binge drinking frequently (more than four occasions in the last month). Lenient parental alcohol norms and a low level of trustful communication with parents were associated with a higher intake at the most recent school party and with the frequency of binge drinking. Joint analyses showed that these associations persisted across different levels of school level alcohol intake and levels of trustful communication with parents. CONCLUSIONS: Among high school students, parental alcohol norms were strongly associated with alcohol intake and consistently so across different levels of school level alcohol intake and level of trustful communication with parents. This indicates that the role of parents in preventing excessive drinking is important, even in older adolescents.

Objectives of this study were to assess (1) prevalence of worries and symptoms of distress, and (2) perceived change in symptoms of distress by sociodemographic factors and preexisting vulnerabilities, among young Danes under the first COVID-19 related lockdown. Data were derived from online surveys, collected 7th-18th of May 2020. The study population included 11,245 young people (15-20 years of age), of which 1807 had participated in The Danish National Youth Study 2019 (DNYS19). Descriptive statistics and linear regressions analyses, including robust standard errors, were performed. All analyses were based on cross-sectional data, except analyses of preexisting vulnerabilities among responders from DNYS19. Few young people were very worried to get infected with coronavirus. Females reported a higher frequency of symptoms of distress than males. Perceived change in symptoms of distress, did not vary systematically based on age, cohabitation, nor physical health conditions. Individuals working, perceived a lower increase in symptoms of distress, than those studying etc. Females with symptoms of anxiety pre-pandemic, mental health disorders, and in families with economic hardship had a marginal higher perceived increase in symptoms of distress, than females without these difficulties. The tendencies were similar but nonsignificant among males, and for symptoms of depression pre-pandemic. In conclusion, during the lockdown, young females reported a higher frequency of symptoms of distress than males, and individuals with symptoms of anxiety pre-pandemic, mental health disorders, and in families with economic hardship were more likely to perceive the lockdown to be associated with an increase in symptoms of distress, than individuals without these difficulties.

Background Little is known about the impact of pregnancy on long-term cardiovascular health in individuals with congenital heart disease (CHD). We aimed to determine if giving birth in patients with CHD is associated with higher risk of long-term cardiovascular morbidity. Methods and Results We studied a cohort of 1262 individuals with CHD giving birth (live or still) from 1993 to 2015 using Danish nationwide registers. We randomly sampled a comparison cohort matched on age of women with CHD who had not given birth at the time. We balanced the 2 cohorts on baseline demographic (eg, education) and clinical variables (eg, CHD severity) using inverse probability of treatment weighting. Individuals were followed for critical (eg, heart failure), other cardiovascular morbidity (eg, arrhythmia), and cardiac surgery/interventions after pregnancy. Individuals were followed for median 6.0 years (interquartile range 3.2-9.2). Among individuals giving birth the incidence rate per 1000 person-years was 1.6, 10.0, and 6.0 for critical and other cardiovascular morbidity and cardiac surgery, respectively. There was no overall difference in risk of neither critical and other cardiovascular morbidity nor cardiac surgery among individuals who gave birth and individuals who did not; adjusted hazard ratios (aHR) were 0.74 (95% CI, 0.37-1.48), 0.88 (95% CI, 0.65-1.19), and 0.78 (95% C,I 0.54-1.12), respectively. However, individuals with obstetric complications had a higher long-term risk of other cardiovascular morbidity (aHR, 1.85; 95% CI, 1.07-3.20). Conclusions Giving birth seemed not to be associated with a higher risk of long-term cardiovascular morbidity among women with CHD. However, individuals having obstetric complications had a higher risk of other cardiovascular morbidity in the long term.

BACKGROUND: Obesity is associated with adverse labor market outcomes. We examine whether undergoing bariatric surgery is associated with better labor market outcomes such as lower risks of unemployment and sickness absence. METHODS: This is a register-based cohort study of 9126 patients undergoing bariatric surgery from 2005 to 2013 and a reference group of 10,328 individuals with obesity. Age: 18-60 years, body mass index (BMI): 32-60 kg/m2. Participants were either working, unemployed, or on sickness absence at baseline. Inverse probability of treatment weighting was used to account for baseline differences between the two groups. Relative risk ratios of labor market participation were estimated at 1 year, 3 years, and 5 years of follow-up. RESULTS: Women who had undergone bariatric surgery had a higher risk of unemployment 1 year (RRR = 1.20 (95% CI: 1.02-1.41)) and 5 years (RRR = 1.23 (95% CI: 1.05-1.44)) after surgery; however, men with bariatric surgery had a lower risk of unemployment after 5 years (RRR = 0.71 (95% CI: 0.55-0.92)). The risk of sickness absence was higher at all follow-up time points for both men and women who had undergone bariatric surgery compared with non-operated references with obesity. CONCLUSIONS: Men undergoing bariatric surgery had a lower risk of unemployment 5 years after surgery compared with non-operated men with obesity; however, women presented a higher risk of unemployment after 5 years. The risk of sickness absence was higher for both men and women up to 5 years after undergoing bariatric surgery.

The aim was to test the hypothesis that parental alcohol problems and low socioeconomic position would be associated with higher odds ratio of emotional symptoms and depression as compared to high socioeconomic position and parental alcohol problems. Data came from Danish National Youth Study 2014, a web-based national survey with 75,853 high school and vocational school students participating, merged with register-data on family socioeconomic position. Multi-level logistic regression models (nesting participants within schools) were used to assess the association between perceived parental alcohol problems and frequent emotional symptoms and depression and effect modification by financial strains in the family, family income, or parental educational level. All analyses were adjusted for age, sex, education, immigration status, and cohabitation with parents. Young people with parental alcohol problems had higher odds ratio of experiencing frequent emotional symptoms (OR = 1.56 [1.46-1.66]) and depression (OR = 2.07 [1.88-2.28]), compared to young people without parental alcohol problems. There was no effect modification between severity of parental alcohol problems and the measures of socioeconomic position on the odds ratio of frequent emotional symptoms and depression. This study found that young people with parental alcohol problems in all social strata had higher odds ratios of frequent emotional symptoms and depression compared to young people without parental alcohol problems; the more severely they had been affected by parent's alcohol problems, the higher the odds ratios of frequent emotional symptoms and depression.

AIMS: To estimate the risks of 12 types of somatic disease-alcohol-related, blood, cancer, circulatory, digestive, endocrine and metabolic, genitourinary, infectious, musculoskeletal, nervous, respiratory and skin-in individuals with parental alcohol use disorder (AUD) versus a reference population, and to estimate the risks of all-cause mortality and of death from an alcohol-related cause. DESIGN: Matched cohort study followed-up through nation-wide health registries. Cox proportional hazards models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs). SETTING: Denmark. PARTICIPANTS: A total of 14 008 individuals born 1962-2003 of parents with AUD and 139 087 reference offspring randomly selected from the Danish Civil Registration System were followed from their 15th birthday and onward during 1970-2018. Follow-up time ranged between 2 423 955 and 3 208 366 person-years for somatic diseases and was 3 214 411 person-years for all-cause and alcohol-related mortality. MEASUREMENTS: Information on somatic disease was obtained from the Danish National Patient Registry. Causes of death were obtained from the Danish Cause of Death Registry. FINDINGS: Individuals of parents with AUD had a higher risk of alcohol-related diseases (HR = 2.70, 95% CI = 2.24-3.24) compared with the reference individuals. Higher HRs among individuals with parental AUD compared with reference individuals were also observed in all other somatic diseases except for cancer. All-cause mortality (HR = 1.80, 95% CI = 1.63-2.00) and alcohol-related mortality (HR = 3.28, 95% CI = 2.11-5.08) were higher among individuals of parents with AUD compared with the reference individuals. No significant differences were found in relation to the gender of either parents or offspring. CONCLUSIONS: In Denmark, parental alcohol use disorder appears to predict alcohol-related and non-alcohol-related somatic morbidity and mortality in offspring.

BACKGROUND: The literature about the impact of congenital heart disease (CHD) on the length of hospital stay after delivery is limited, and nonexisting in a country with free and equal access to healthcare. We aimed to examine the hypothesis that Danish women with CHD have a longer hospital stay after delivery compared to women without CHD. Secondarily, we aimed to examine the hypothesis that cesarean section modifies the association. METHODS: The study was a national cohort study using Danish nationwide registers in 1997-2014. Maternal CHD was categorized as simple, moderate, or complex CHD. The comparison group consisted of women without CHD. Outcome of interest was length of hospital stay after delivery registered in complete days. Mode of delivery was categorized as cesarean section or vaginal delivery. Data was analyzed using a generalized linear model with a Poisson distribution. RESULTS: We included 939,678 births among 551,119 women. Women without CHD were on average admitted to the hospital for 3.6 (SD 3.7) days, whereas women with simple, moderate, and complex CHD were admitted for 3.9 (SD 4.4), 4.0 (SD 3.8) and 5.1 (SD 6.7) days, respectively. The adjusted length of hospital stay after delivery was 12% (relative ratio (RR) = 1.12, 95% confidence interval (CI) 1.07-1.18), 14% (RR = 1.14, 95% CI: 1.07-1.21), and 45% (RR = 1.45, 95% CI: 1.24-1.70) longer among women with simple, moderate, and complex CHD, respectively, compared to women without CHD. The association between maternal CHD and length of hospital stay was not modified by mode of delivery (p-value of interaction = 0.62). Women who gave birth by cesarean section were on average admitted to the hospital for 2.7 days longer compared to women with vaginal delivery. CONCLUSION: The hospital stay after delivery was significantly longer among women with CHD as compared to women without CHD. Further, higher complexity of CHD was associated with longer length of stay. Cesarean section did not modify the association.

BACKGROUND: Mental health represents an important public health issue, and mental health problems have been linked to school dropout. This study aimed to identify mental health groups of high school students using both positive and negative aspects of mental health and to examine whether these mental health groups longitudinally predict school dropout. METHODS: We conducted latent class analysis using the Danish National Youth Study 2014 (n = 60,526; mean 17.9 years) to identify clustering of mental health (11 items covering positive and negative aspects of emotional wellbeing and functioning in daily life), separately by sex. The relationship with subsequent school dropout was examined using logistic regression models, adjusted for age, ethnicity and socioeconomic status. Information on dropout status was obtained through educational registers. RESULTS: School dropout rates was highest among first-year students. Four mental health groups were identified: Flourishing (females: 38%, males: 55%), moderate mental health (females: 15%, males: 20%), emotionally challenged (females: 28%, males: 15%) and languishing (females: 19%, males: 10%). Compared to the flourishing group, adjusted odds ratio (AOR) for dropout were 3.43 (95% CI: 2.98, 3.95), 1.73 (95% CI: 1.45, 2.06) and 1.76 (95% CI: 1.52, 2.04) in the languishing, moderate mentally healthy and emotional challenged females. Results in males were comparable. CONCLUSIONS: Mental health in high school students cluster together in four categories among both males and females. Students who are languishing, emotionally challenged or moderate mentally healthy have about 1.5-fold to threefold higher risk of dropping out of high school compared with flourishing students. Universal mental health interventions may be a promising strategy, particularly in the first year of high school where most students drop out of school.
