ObjectiveTo explore the prevalence of poor social support and loneliness among people with chronic headache, and how these might be effect modifiers in the relationships between chronic headache and stress, medication overuse, and self-rated health.BackgroundPoor social support and loneliness are consistently linked to worse health outcomes. There are few epidemiologic studies on their effect on headache.MethodsThe Danish Capital Region Health Survey, a cross-sectional survey, was conducted in 2017. Participants were asked about headache, pain medication use, social support, loneliness, perceived stress, and self-rated health. Data were accessed from sociodemographic registers. Logistic regression analyses were performed to test for effect modification.ResultsThe response rate was 52.6% (55,185 respondents) and was representative of the target population. People with chronic headache were more likely to report poor social support and loneliness compared to those without chronic headache ( p ConclusionPoor social support and loneliness were prevalent among people with chronic headache. The combination of chronic headache and poor social support or loneliness showed higher odds ratios for stress, medication overuse, and poor self-rated health compared to those with good social support and low loneliness scores. The effect of loneliness in the relationship between chronic headache and medication overuse warrants further study.

Aim: This article aims to describe the study design, including descriptive statistics on changes in response rates, characteristics associated with response and response mode distribution, in the Danish National Health Survey (DNHS) in 2010, 2013 and 2017. Methods: Each survey was based on five regional stratified random samples and one national random sample drawn from the Danish Civil Registration System. The subsamples were mutually exclusive. Around 300,000 individuals (aged ⩾16 years) were invited to participate in each survey using a mixed-mode approach (paper/web). A questionnaire with a minimum of 52 questions was used in all subsamples. In 2010 and 2013, invitations were sent via the regular postal service, whereas a secure electronical mail service was used to invite the majority (around 90%) in 2017. Weights accounted for survey design and non-response. Results: Participation decreased from 59.5% in 2010 to 54.0% in 2013 after which it increased to 58.7% in 2017. The proportion answering the web questionnaire increased from 31.0% to 77.4% between 2013 and 2017 and varied from 73.8% to 79.7% between the subsamples in 2017. Overall, the response rate was low among young men and old women and among individuals who were unmarried, had low sociodemographic status, were from ethnic minority backgrounds or were living in the eastern part of Denmark. Conclusions: The survey mode, response mode distribution as well as response rate have changed over time. Weights to handle non-response can be applied to accommodate possible problems in generalising the results. However, efforts should continuously be made to ensure that response is missing at random.

Excessive intake of sodium is a dietary risk factor for morbidity and mortality. Currently, intake of sodium is much higher than the recommended level in most western countries, and effective strategies to reduce population sodium intake are lacking. The objective of the present study was to investigate the effect of two different sodium reduction strategies on the intake of sodium, potassium, and the sodium to potassium ratio among Danish families The study was a 4-month, single-blinded, cluster randomized controlled trial with a parallel design. Eighty-nine healthy Danish families, with a minimum of one child and one parent (n = 309), were randomly assigned to receive sodium-reduced bread (Intervention A), sodium-reduced bread and dietary counseling (Intervention B) or regular sodium bread (Control). The primary outcome was change in daily sodium intake, measured by 24-h urinary sodium excretion. Secondary outcomes included changes in dietary potassium and the sodium to potassium ratio. No significant differences in daily sodium intake were observed in the two intervention groups compared with the control. When analyzing the results separately for children and adults, a reduction in dietary sodium of 0.6 g/day (−1.0, −0.2), p = 0.005 occurred among adults in intervention B compared with control. This study demonstrates that providing sodium-reduced bread in combination with dietary counseling is an effective strategy to reduce dietary sodium among adults, but the effect is lacking in children. The study was not able to show significant effects when providing sodium-reduced bread alone in neither adults nor children.

OBJECTIVES To evaluate safety and effectiveness of prophylactic anticoagulation with low molecular weight heparin (LMWH) in individuals hospitalised for COVID-19. METHODS Using healthcare records from the capital region of Denmark (March 2020-February 2021) and Karolinska University Hospital in Sweden (February 2020-September 2021), we conducted an observational cohort study comparing clinical outcomes 30 days after admission among individuals hospitalised for COVID-19 starting prophylactic LMWH during the first 48 hours of hospitalisation with outcomes among those not receiving prophylactic anticoagulation. We used inverse probability weighting to adjust for confounders and bias due to missing information. Risk ratios, risk differences and robust 95% confidence intervals (CI) were estimated using binomial regression. Country-specific risk ratios were pooled using random-effects meta-analysis. RESULTS We included 1692 and 1868 individuals in the Danish and Swedish cohorts. Of these, 771 (46%) and 1167 (62%) received prophylactic LMWH up to 48 hours after admission. The combined mortality in Denmark and Sweden was 12% (N=432) and the pooled risk ratio was 0.89 (CI 0.61-1.29) comparing individuals who received LMWH to those who did not. The relative risk of ICU admission was 1.12 (CI 0.85-1.48), while we observed no increased risk of bleeding (RR 0.60, 0.14-2.59). The relative risk of venous thromboembolism was 0.68 (CI: 0.33-1.38) in Sweden. Less than 5 VTE events were observed among individuals receiving LMWH in Denmark, preventing a meaningful analysis. CONCLUSION We found no benefit on mortality with prophylactic LMWH and no increased risk of bleeding among COVID-19 patients receiving prophylactic LMWH. Objectives: To evaluate safety and effectiveness of prophylactic anticoagulation with low molecular weight heparin (LMWH) in individuals hospitalised for COVID-19. Methods: Using healthcare records from the Capital Region of Denmark (March 2020-February 2021) and Karolinska University Hospital in Sweden (February 2020-September 2021), we conducted an observational cohort study comparing clinical outcomes 30 days after admission among individuals hospitalised for COVID-19 starting prophylactic LMWH during the first 48 hours of hospitalisation with outcomes among those not receiving prophylactic anticoagulation.

Risk ratios, risk differences and robust 95% confidence intervals (CI) were estimated using binomial regression. Country-specific risk ratios were pooled using random-effects meta-analysis. Results: We included 1692 and 1868 individuals in the Danish and Swedish cohorts. Of these, 771 (46%) and 1167 (62%) received prophylactic LMWH up to 48 hours after admission. The combined mortality in Denmark and Sweden was 12% (N = 432) and the pooled risk ratio was 0.91 (CI 0.60-1.38) comparing individuals who received LMWH to those who did not. The relative risk of ICU admission was 1.12 (0.76-1.66), while we observed no increased risk of bleeding 0.63 (0.13-2.94). The relative risk of venous thromboembolism was 0.80 (0.43-1.47). Conclusion: We found no benefit on mortality with prophylactic LMWH and no increased risk of bleeding among COVID-19 patients receiving prophylactic LMWH.

The aim was to examine the effects of replacing self-reported leisure-time sedentary behavior with sleep, light-to-moderate physical activity, or vigorous physical activity on incident diabetes among Danish adults using isotemporal substitution modeling. Participants >= 25 years from the Danish Capital Region Health Survey 2007 (N = 69 800, response rate 52.3%), 2010 (N = 95 150, response rate 52.3%), and 2013 (N = 95 150, response rate 43.5%) were included. Information on daily sleep duration, leisure-time sedentary behavior, and movement behaviors was collected by questionnaire. Information on incident diabetes was obtained from National registers. Analyses included Cox proportional hazards regression models and isotemporal substitution analyses, with time (in years) from baseline to incident diabetes or censoring December 31, 2017. Potential confounders, sex, age, BMI, ethnicity, education, smoking, inflammatory joint disease, perceived stress, physical and mental component scale and work status, were included. Out of N = 87 339 in the final study sample, n = 3007 had incident diabetes during a mean follow-up time of 7.4 years. Adults with incident diabetes included more men, higher mean age, and higher BMI, compared to respondents without incident diabetes. Theoretically substituting 30 minutes of leisure-time sedentary behavior with light-to-moderate PA (HR: 0.96; 95% CI: 0.94; 0.98) or with vigorous PA (HR: 0.82; 95% CI: 0.72; 0.94) decreased the risk of incident diabetes. We found no change in incident diabetes risk of substituting sedentary time with sleep (HR: 1.00; 95% CI: 0.97; 1.02). Substituting 30 minutes per day of leisure-time sedentary behavior with light-to-moderate or vigorous PA may significantly reduce the risk of incident diabetes among adults.

INTRODUCTION The social pressure placed on smokers today might potentially lead to an increasing level of stress. We investigated if the proportion of persons with high stress level had increased over time more in smokers than in non-smokers.METHODS Data were obtained from repeated cross-sectional surveys of The Capital Region Health Survey conducted in 2010, 2013 and 2017. Survey data were weighted for survey design and non-response, and linked to national register data. Cohens Perceived Stress Scale (PSS-10) score was used. Logistic regression analyses, based on 136608 citizens' self-reports, were adjusted for sex, age, education level, employment, and alcohol intake (and loneliness, in analysis investigating the associations between tobacco consumption and high stress level).RESULTS A significantly higher proportion of citizens reported a high stress level in 2017 compared with 2010 and 2013 but there was not a greater increase in smokers than in non-smokers. Daily smoking men had 69% higher odds of reporting perceived high stress level and daily smoking women had 36% higher odds, than never smokers of the same sex. There was a significant trend between higher daily tobacco consumption and a higher proportion of smokers with high stress level.CONCLUSIONS The increase in high stress level over time occurred independently of smoking status. Daily smokers had the highest odds of perceived high stress level, and a higher daily tobacco consumption was associated with a higher proportion of smokers with high stress level. Smoking cessation programs should, to a higher degree, consider implementing stress-coping elements to prevent relapse.

Background Patients with asthma are heterogeneous in clinical presentation and in response to treatment. Despite this, tools to guide treatment are limited and include mainly measures of eosinophilic inflammation and symptoms. Airway hyperresponsiveness (AHR) to mannitol is present in patients across inflammatory phenotypes and improve with inhaled corticosteroids. Objective To investigate whether measuring AHR to mannitol in addition to eosinophilic inflammation and symptoms adds information to the phenotypic characterization of patients with asthma. Methods A total of 317 patients with asthma from 6 different cohorts were included in the analysis. All patients had measures of AHR to mannitol, blood eosinophils, and Asthma Control Questionnaire 5 available. A cluster analysis using Ward minimum variance method was performed. The distribution of fraction of exhaled nitric oxide, immunoglobulin E, lung function, induced sputum inflammatory cell count, age of onset, and severity of disease was compared between clusters. Results Four clusters were identified. Three of the clusters had proportionate levels of AHR, eosinophilic inflammation, and symptoms, but 1 cluster presented with low levels of eosinophilic inflammation and a significant symptom burden. Half of the subjects in this cluster presented with AHR to inhaled mannitol. Lung function, fraction of exhaled nitric oxide, body mass index, and immunoglobulin E were normal. Conclusions Information on AHR to mannitol in addition to blood eosinophils and symptoms identifies a subgroup of asthma patients with symptomatic, noneosinophilic disease. Airway hyperresponsiveness to mannitol may provide a treatable trait in a subgroup of patients with noneosinophilic asthma.

Objectives: The objective of the present study was to investigate the relationship between price and sales volume of non-alcoholic sugar-sweetened beverages (SSBs), diet drinks, sweets and chocolates, including own and cross price elasticity to further quantify the potential impact of price. Methods: The study was based on retail scanner data for grocery sales from retail outlet chains in Denmark during the year 2008–2015. A fixed-effects model was used to estimate the association between price and sales volume, using own price and cross price elasticity. Results: Sales volume of all sugary products except for chocolates were significantly negatively associated with price. Own price elasticity varied from −0.3 to −0.4 for drinks and sweets indicating that a 10% increase in price would cause a reduction in sales by 3 or 4%. A 10% increase in price of carbonated SSBs would increase sales of diet drinks by 7%. Cross price elasticities for other products were not significant. Conclusions: The results of the present study demonstrated significant negative associations between changes in price and changes in the sale of SSBs, diet drinks and sweets.

The aim was to examine the effects of two different salt reduction strategies on selected cardiovascular risk factors. The study was a four-month cluster randomised controlled study. Eighty-nine healthy Danish families (309 individuals) were randomly assigned to either (A) gradually salt-reduced bread, (B) gradually salt-reduced bread and dietary counselling to further reduce salt intake and increase potassium intake or (C) standard bread (control). The effect was assessed using linear mixed models. Intention to treat analyses comparing changes in the three groups showed a significant reduction in body fat percent (&minus, 1.31% (&minus, 2.40, &minus, 0.23)) and a borderline significant reduction in total plasma cholesterol (&minus, 0.25 mmol/L (&minus, 0.51, 0.01) and plasma renin (&minus, 0.19 pmol/L (&minus, 0.39, 0.00) in group A compared to the control group. Adjusted complete case analyses showed a significant reduction in total plasma cholesterol (&minus, 0.29 mmol/L (&minus, 0.50, 0.08), plasma LDL cholesterol (&minus, 0.08 mmol/L (&minus, 0.15, 0.00)), plasma renin (&minus, 0.23 pmol/L (&minus, 0.41, 0.05)), plasma adrenaline (&minus, 0.03 nmol/L (&minus, 0.06, 0.01)) and body fat percent (&minus, 1.53% (&minus, 2.51, 0.54)) in group A compared to the control group. No significant changes were found in group B compared to the control group. In conclusion, receiving sodium reduce bread was associated with beneficial changes in cardiovascular risk factors. No adverse effects were observed.

Excess dietary sodium plays an important role in hypertension, a leading risk factor for cardiovascular disease (CVD). To counteract some of the negative effects of sodium, an increased intake of potassium has shown beneficial effects on blood pressure. In fact, the sodium to potassium ratio might be a stronger risk factor for CVD than either sodium or potassium alone. The objective of the present study was to estimate the effect of A) a salt reduction strategy (providing salt reduced bread) and B) a salt reduction and potassium promoting strategy (providing salt reduced bread combined with dietary counselling), on intake of sodium, potassium and the sodium/potassium ratio. The study is a 4-month cluster randomized controlled trial with families randomly assigned to either intervention A, intervention B or control. Participants in intervention A received bread gradually reduced in salt content from 1.2 g salt/100 g to 0.6 g salt/100 g in ryebread and 0.4 g salt/100 g in wheat bread. Participants in intervention B received the same salt reduced bread and in addition dietary counselling on how to eat food with less salt and more potassium. The control group received standard bread (1.2 g salt/100g). Sodium and potassium intake were measured through three consecutive 24-hour urine measurements in adults and one in children at baseline and follow-up. Changes in outcomes were assessed using linear mixed models. Eighty-nine families, including 155 adults (46.5 % men) and 156 children (51.9 % boys), from the suburb of Copenhagen, Denmark, participated in the study. The sodium/potassium ratio was significantly reduced by -0.57 ± 0.19 mmol/L (P = 0.003) in intervention B compared to control group, resulting from a non-significant lower sodium and increased potassium intake. No significant differences were found between intervention A and control group (preliminary results). These findings support future actions to reduce salt intake, focusing on a combination of structural and educational strategies.

Dietary salt intake in most countries is far beyond the recommended level and many countries have initiated national programs to decrease salt intake. However, potential adverse effects of reducing salt intake in the general population are currently discussed. Hence some randomized studies have shown adverse effects on plasma lipids, the renin-angiotensin-aldosterone system and the sympathetic nervous system, which may again increase risk of CVD. These findings are however mainly based on short-term studies with a very large acute salt reduction. This study aims to explore the effect of gradually reducing salt intake in a real life setting according to recommendations, and to examine the effect of different salt reduction strategies among families.The study was a 4-month cluster randomized controlled trial with families randomly assigned to either A) salt reduced bread, B) salt reduced bread and dietary counselling or C) standard bread (control) Participants in intervention A received bread gradually reduced in salt content from 1.2 g salt/100 g (regular) to 0.6 g salt/100 g in ryebread and 0.4 g salt/100 g in wheat bread. Participants in intervention B received the same salt reduced bread and in addition, they received dietary advise on how to further reduce their salt intake and promote potassium. The control group received regular bread. Changes in outcomes were assessed using linear mixed models.Results: A total of 89 families (155 adults; 156 children) from the suburb of Copenhagen, Denmark, participated in the study (February-July 2018). A total of 291 (94%) participants completed the intervention. Results presented are preliminary.Intention to treat analyses showed no significant effects of the salt reduction intervention on changes in systolic and diastolic blood pressure, plasma triglyceride. A small, but significant (-0.26 mmol/l; P = 0.02) decrease in total plasma cholesterol was shown in intervention group A. A similar, but non-significant, tendency was found in intervention group B. (more results will follow).Subgroup analyses, including only participants in the intervention groups that decreased their salt intake by at least 20% from baseline to 4-month follow-up, showed a significant decrease in diastolic (-3.5 mmHg; P < 0.0001) and systolic (-6.3 mmHg; P < 0.0001) blood pressure, total plasma cholesterol (-0.25 mmol/l; P = 0.0009), LDL plasma cholesterol (logarithm transformed) (-6%; P = 0.03) and plasma triglyceride (logarithm transformed) (-17%; P = 0.04). No significant effects were found for HDL plasma cholesterol, aldosterone, renin, plasma glucose and HbA1c.Conclusion: Reduced salt intake were associated with beneficial changes in cardiovascular risk factors. No adverse effects were observed.

Reductions in salt intake have the potential to markedly improve population health at low cost. Real life interventions that explore the feasibility and health effects of a gradual salt reduction lasting at least four weeks are required. The randomized controlled SalT Reduction InterVEntion (STRIVE) trial was developed to investigate the metabolic, behavioral and health effects of four months of consuming gradually salt reduced bread alone or in combination with dietary counselling. This paper describes the rationale and methods of STRIVE. Aiming at 120 healthy families, participants were recruited in February 2018 from the Danish Capital Region and randomly allocated into: (A) Salt reduced bread, (B) Salt reduced bread and dietary counseling, (C) Standard bread. Participants were examined before the intervention and at four months follow-up. Primary outcome is change in salt intake measured by 24 h urine. Secondary outcomes are change in urine measures of potassium and sodium/ potassium ratio, blood pressure, plasma lipids, the renin-angiotensin system, the sympathetic nervous response, dietary intake as well as salt taste sensitivity and preferences. The results will qualify mechanisms affected during a gradual reduction in salt intake in compliance with the current public health recommendations.

The objective of the present study was to investigate the relationship between price and sales volume of non-alcoholic sugar-sweetened beverages (SSBs), diet drinks, sweets and chocolates, including own and cross price elasticity to further quantify the potential impact of price.The study was based on retail scanner data for grocery sales from retail outlet chains in Denmark during the year 2008-2015. A fixed-effects model was used to estimate the association between price and sales volume, using own price and cross price elasticity.Sales volume of all sugary products except for chocolates were significantly negatively associated with price. Own price elasticity varied from -0.3 to -0.4 for drinks and sweets indicating that a 10% increase in price would cause a reduction in sales by 3 or 4%. A 10% increase in price of carbonated SSBs would increase sales of diet drinks by 7%. Cross price elasticities for other products were not significant.The results of the present study demonstrated significant negative associations between changes in price and changes in the sale of SSBs, diet drinks and sweets.

Objective: To estimate national relative survival of low and high grade non-invasive papillary urothelial carcinoma (Ta LG and Ta HG) and urothelial carcinoma in situ (CIS). Materials and methods: All Danish citizens (17,941 patients) with a primary urothelial bladder tumour diagnosis in the period 2000– 2010 were followed until 1 January 2016 and recorded in the Danish Bladder Cancer Cohort database. Survival was compared to the background population matched on age and gender and adjusted by civil status, income, education, and comorbidity. Results: Patients treated in daily practice with Ta LG have 46% (HR = 1.46 (1.42–1.51) p < 0.001) higher risk of death compared to a background population matched for age and gender. This risk of death ceases to 28% (HR = 1.28 (1.24–1.32) p < 0.001) after adjustment for civil status, income, education, and comorbidity. Relative survival of Ta LG patients is 0.94 (0.93–0.95). These estimates are constant throughout the observation period. Significantly higher mortality is found for patients with Ta HG and CIS, but, in contrast to Ta LG, the relative risk of death of Ta HG (HR = 1.79 (1.69–1.90) p < 0.001) and CIS (HR = 2.02 (1.79–2.26) p < 0.001) decreases considerably after 5 years survival (HR = 1.43 (1.30–1.57) p < 0.001 and HR = 1.64 (1.36–1.98) p < 0.001, respectively). Conclusion: Patients with Ta LG have a continuous lower survival and a 28% higher risk of death at any time compared to a matched background population when treated in daily practice.

BACKGROUND: A small proportion of patients account for the majority of health care costs. This group is often referred to as high-cost users (HCU). A frequently described characteristic of HCU is chronic disease. Yet, there is a gap in understanding the economic burden of chronic diseases associated with HCU to different types of health care services. OBJECTIVE: To analyze which frequent chronic diseases have the strongest association with HCU overall, and HCU in hospital, primary care, and prescription medication. DESIGN: This is a register-based observational study on Danish health service costs for various diseases in different medical settings. PARTICIPANTS: A total of 1,350,677 individuals aged ≥ 18 years living in the Capital Region of Denmark by 1 January 2012 were included. MAIN MEASURES: Chronic diseases, costs, and sociodemographic data were extracted from the nationwide registers, including data from hospitals, primary care, and medicine consumption. These information were merged on an individual level. KEY RESULTS: Cancer, mental disorders except depression, and heart diseases have the strongest association with HCU overall. Mental disorders except depression were in the three diseases most prevalent in HCU in all the three health care services. CONCLUSIONS: Our results show that the chronic diseases that have the strongest association with HCU differ between different types of health care services. Our findings may be helpful in informing future policies about health care organization and may guide to different prevention, treatment, and rehabilitation strategies that could lessen the burden in the hospital.

Literature suggests that people living in areas with a wealth of unhealthy fast food options may show higher levels of fast food intake. Multilevel logistic regression analyses were applied to examine the association between GIS-located fast food outlets (FFOs) and self-reported fast food intake among adults (+ 16 years) in the Capital Region of Denmark (N = 48,305). Accessibility of FFOs was measured both as proximity (distance to nearest FFO) and density (number of FFOs within a 1 km network buffer around home). Odds of fast food intake ≥ 1/week increased significantly with increasing FFO density and decreased significantly with increasing distance to the nearest FFO for distances ≤ 4 km. For long distances (>4 km), odds increased with increasing distance, although this applied only for car owners. Results suggest that Danish health promotion strategies need to consider the contribution of the built environment to unhealthy eating.

Background The health benefits of active commuting are well established, but little is known about the temporal changes in active commuting across sociodemographic groups. Aim To examine temporal changes in active commuting in the Capital Region of Denmark from 2007 to 2017 and to examine whether these changes differed across gender, age, educational attainment, BMI, distance to work/educational institution, and place of residence. Method The study was based on four waves of “The Danish Capital Region Health Survey (DK-CRHS)” conducted in 2007, 2010, 2013 and 2017. The pooled study sample included 102.792 individuals aged 25–79 years old. Results From 2007-2017 the overall prevalence of active commuters increased from 71.8% to 76.4%. Also, the Odds Ratio (OR) of being an active commuter increased significantly among men, individuals aged 25–34 and 35–44 years of age, all educational attainment groups, all BMI groups except BMI 5 km, and in all groups by place of residence (urban, suburban and rural). Survey year modified the effect of gender, age, educational attainment, distance to work/education, and place of residence, but not the effect of BMI on the probability of being an active commuter. Conclusion Active commuting has become more prevalent among adults living in the Capital Region of Denmark, but temporal changes from 2007 to 2017 differed between sociodemographic groups. Findings may help inform future planning and policymaking to secure targeted interventions for continuous promotion of active commuting across all sociodemographic groups.
