Housing conditions and risk of incident COPD: a Danish cohort study, 2000-2018.

BACKGROUND: More knowledge is needed on the risk of developing chronic obstructive pulmonary disease (COPD) associated with housing conditions and indoor environment based on cohort studies with a long follow-up time. OBJECTIVE: To examine the association between housing conditions and indoor environment and the risk of developing COPD. METHODS: In this cohort study, we followed 11,590 individuals aged ≥ 30 years free of COPD at baseline. Information on incident COPD and housing conditions and indoor environment was obtained from the Danish national registers and the Danish Health and Morbidity Survey year 2000. Poisson regression of incidence rates (IRs) were used to estimate incidence rate ratios (IRRs) of COPD. RESULTS: The overall IR of COPD was 8.6 per 1,000 person-years. Individuals living outside the biggest cities vs. living in the biggest cities (≥ 50,000) had a lower risk of COPD (200-4,999; IRR 0.77 (95% CI 0.65-0.90). Individuals living in semi-detached houses had a higher risk compared to individuals living in detached houses (IRR 1.29 (95% CI 1.07-1.55)). Likewise, individuals living in rented homes had a higher risk (IRR 1.47 (95% CI 1.27-1.70)) compared to individuals living in owned homes. The IR of COPD was 17% higher among individuals living in dwellings build > 1982 compared with individuals living in older dwellings (< 1962), not statistically significant though (IRR 0.83 (95% CI 0.68-1.03)). Likewise, the IR of COPD was 15% higher among individuals living in the densest households compared with individuals living in the least dense households, not statistically significant though (IRR 1.15 (95% CI 0.92-1.45)). This was primary seen among smokers. There was no difference in risk among individuals with different perceived indoor environments. Overall, similar patterns were seen when stratified by smoking status with exception of perceived indoor environment, where opposite patterns were seen for smokers and never smokers. CONCLUSION: Individuals living in semi-detached houses or rented homes had a higher risk of developing COPD compared to individuals living in detached or owned homes. Individuals living in cities with < 50.000 residents had a lower risk of COPD compared to individuals living in cities with ≥ 50.000 residents.

Trends in the use of complementary and alternative medicine between 1987 and 2021 in Denmark.

BACKGROUND: Complementary and alternative medicine (CAM) has been widely and increasingly used worldwide during the past decades. Nevertheless, studies in long-term trends of CAM use are limited. The aim of this study was to assess long-term trends in the prevalence of CAM use (both overall and for specific CAMs) between 1987 and 2021 in the adult Danish population and to examine certain sociodemographic characteristics of CAM users. METHODS: Data derived from nationally representative health surveys in the general adult population (≥ 16 years) in Denmark (the Danish Health and Morbidity Surveys) conducted in 1987, 1994, 2000, 2005, 2010, 2013, 2017, and 2021. The response proportion declined from 79.9% in 1987 to 45.4% in 2021. CAM use was assessed by questions on ever use of specific types of CAMs and overall use within the past 12 months. Differences in use of CAMs across educational levels were assessed using the Slope Index of Inequality (SII). RESULTS: An overall increase in the prevalence of CAM use within the past 12 months was found between 1987 (10.0%) and 2021 (24.0%). However, a stagnation was observed between 2010 and 2017, after which the prevalence decreased in 2021. In all survey waves, the prevalence was higher among women than men. For both sexes, the prevalence tended to be highest among respondents aged 25-44 years and 45-64 years. The group with 13-14 years of education had the highest prevalence of CAM use compared to the other educational groups (< 10 years, 10-12 years, and ≥ 15 years). SII values for both men and women increased between 1987 and 2021, which indicates an increase in differences of CAM use across educational groups. In all survey waves the most frequently used CAMs included massage and other manipulative therapies, acupuncture, and reflexology. CONCLUSIONS: The use of CAM has increased markedly within the last decades and recently stagnated at high levels, which underlines the importance of securing high quality information and education for the public, health professionals, and legislators to ensure and promote safe use of CAMs.

Do animation videos increase participation in national health surveys? A randomised controlled trial.

BACKGROUND: Declining response proportions in surveys have been observed internationally. Improving response proportions is important for the generalizability of the outcome. The aim of this study was to examine the potential of animation videos to improve response proportions and sample composition in health surveys. METHODS: A randomized trial was embedded in the Danish National Health Survey 2021 (n = 186,113) where the use of animation videos in the digital invitation letter was tested as a mean to increase response proportion. The effect of both demographic-targeted videos and a general video was tested. The sample was stratified into four subsamples; (1) individuals with non-western background and a non-Danish citizenship (n = 9,956), (2) men aged 16-24 years (n = 12,481), (3) women aged 75 years or older (n = 7,815) and (4) the remaining individuals (n = 155,861). The fourth subsample was randomized into two equal sized groups; a group receiving the general video and a control group receiving no video. Each of the first three subsamples was subsequently randomized into three subgroups with 25% receiving the target group video, 25% receiving the general video and 50% receiving no video. A total of four reminders (one digital and three postal) were sent to the eligible population. RESULTS: The use of animation videos resulted in similar or slightly lower overall response proportion compared to the control group. The different animation videos were found to have heterogeneous effects on response proportions. A positive effect was found among men aged 16-24 years before the delivery of the postal reminder for the targeted animation video compared to no video (odds ratio: 1.13; 95% confidence interval: 1.02-1.26). Overall, the targeted animation videos tended to produce higher response proportions than the general animation video. CONCLUSIONS: The heterogeneous effects of the videos suggest that there is some potential for the use of animation videos to improve response proportions and sample composition. The content, target group and timing of evaluation seem to be important for the animation videos to be successful. This warrants further research to better identify in which contexts, in which subgroups and under which circumstances, animation videos are useful to increase response proportions.

Trends in social inequality in mortality in Denmark 1995-2019: the contribution of smoking- and alcohol-related deaths.

BACKGROUND: During the past decades, social inequality in mortality has increased in several countries, including Denmark. Modifiable risk factors, such as smoking and harmful alcohol consumption, have been suggested to moderate the association between socioeconomic position and health-related outcomes. The present study aims to investigate the contribution of smoking- and alcohol-related deaths to the trends in educational inequality in mortality in Denmark 1995-2019 among individuals aged 30-74 years. METHODS: Nationwide data on mortality and highest attained educational level divided into quartiles were derived from administrative registers. Alcohol-related mortality was directly estimated using information on alcohol-related deaths from death certificates. Smoking-related mortality was indirectly estimated using the Peto-Lopez method. The contribution of smoking- and alcohol-related deaths to the social inequality gap in mortality 1995-2019 was calculated. RESULTS: Alongside a decrease in all-cause mortality in Denmark 1995-2019, absolute differences in the mortality rate (per 100 000 person-year) between the lowest and the highest educational quartile increased from 494 to 607 among men and from 268 to 376 among women. Among both men and women, smoking- and alcohol-related deaths explained around 60% of the social inequality in mortality and around 50% of the increase in mortality inequality. CONCLUSION: Smoking and harmful alcohol consumption continue to be important risk factors and causes of social inequality in mortality, with around half of the increase in Denmark 1995-2019 being attributable to smoking- and alcohol-related deaths. Future healthcare planning and policy development should aim at reducing social inequality in modifiable health risk behaviours and their negative consequences.

The Association between Perceived Annoyances in the Indoor Home Environment and Respiratory Infections: A Danish Cohort Study with up to 19 Years of Follow-Up.

The increasing prevalence of reported annoyances in the indoor environment threatens public health. This study aimed to investigate the association between perceived annoyances from the home environment and respiratory infections among individuals with and without asthma or chronic obstructive pulmonary disease (COPD). A total of 16,688 individuals from the Danish Health and Morbidity Survey initiated in 2000 were grouped according to their patterns of perceived annoyances. Information on respiratory infections (all causes, bacterial, viral, and those leading to hospital admissions) was obtained from Danish registers up to 19 years after the survey. Poisson regression of incidence rates (IRs) was applied to estimate incidence rate ratios (IRRs). Annoyances significantly increased the IR for respiratory infections of all causes and bacterial respiratory infections in individuals without asthma or COPD, adjusted IRR 1.16 (95% CI: 1.01, 1.34) and 1.15 (95% CI: 1.02, 1.31), respectively. However, no difference was observed for viral respiratory infections nor hospital admissions. Individuals with asthma or COPD and a high level of annoyances had a non-significantly increased IR in all four analyses of respiratory infections. These findings provide support for perceived annoyances as an important risk factor for respiratory infections.

Social support and risk of mortality in cirrhosis: A cohort study.

Background & Aims: The function and structure of social relationships influence mortality in individuals within the general population. We compared aspects of social relationships in individuals with cirrhosis and a matched comparison cohort and studied their association with health-related quality of life (HRQoL) and mortality in cirrhosis. Methods: Individuals with cirrhosis and comparators were identified among participants of the Danish National Health Surveys 2010-2017. The surveys included questions on functional (social support and loneliness) and structural (living alone/cohabitating and frequency of contacts with relatives and friends) aspects of social relationships and HRQoL (Short Form-12). We estimated associations of aspects of social relationships with HRQoL and all-cause mortality in individuals with cirrhosis through 2020. Results: Of 541 individuals with cirrhosis and 2,157 comparators, low social support (22% in cirrhosis vs. 13% in comparators), loneliness (35% vs. 20%), and living alone (48% vs. 22%) were more frequent in individuals with cirrhosis than comparators, whereas the frequency of contacts with relatives and friends was similar. Except for living alone, weak functional and structural social relationships were associated with lower mental HRQoL in those with cirrhosis. Physical HRQoL was only marginally associated with social relationships. During 2,795 person-years of follow-up, 269 individuals with cirrhosis died. Functional and not structural aspects of social relationships were associated with risk of mortality in cirrhosis. Specifically, the adjusted hazard ratio was 1.4 (95% CI 1.1-1.9), p = 0.011, for low vs. moderate-to-high social support (functional aspect), and 1.0 (95% CI 0.8-1.3), p = 0.85 for living alone vs. cohabitating (structural aspect). Conclusions: Individuals with cirrhosis have weaker functional and structural social relationships than matched comparators. Weak functional relationships are associated with lower mental HRQoL and increased risk of mortality in individuals with cirrhosis. Impact and implications: This study investigated the prevalence of weak social relationships in individuals with cirrhosis and their influence on health-related quality of life and risk of mortality. Individuals with cirrhosis were nearly twice as likely to report low social support, loneliness, and to live alone than a matched comparison cohort. Low social support and loneliness (functional measures of social relationships) were associated with lower mental health-related quality of life and increased risk of mortality risk in cirrhosis, when adjusting for known confounders. We hope that these results will make healthcare providers aware of the functional aspects of the social relationships of individuals with cirrhosis, in addition to the traditional clinical management, and motivate further research of interventions to strengthen the social support of individuals with cirrhosis.

Agreement between self-reported diseases from health surveys and national health registry data: a Danish nationwide study.

BACKGROUND: Agreement may be low when comparing self-reported diseases in health surveys with registry data. The aim of the present study was to examine the agreement between seven self-reported diseases among a representative sample of Danish adults aged ≥16 years and data from medical records. Moreover, possible associations with sociodemographic variables were examined. METHODS: Nationally representative data on self-reported current or previous diabetes, asthma, rheumatoid arthritis, osteoporosis, myocardial infarction, stroke and cancer, respectively, were derived from the Danish National Health Survey in 2017 (N=183 372). Individual-level data were linked to data on the same diseases from medical records in registries. Logistic regression models were used to explore potential associations between sociodemographic variables and total agreement. RESULTS: For all included diseases, specificity was >92% and sensitivity varied between 66% (cancer) and 95% (diabetes). Negative predictive value (NPV) was >96% for all diseases and positive predictive value (PPV) varied between 13% (rheumatoid arthritis) and 90% (cancer). Total agreement varied between 91% (asthma) and 99% (diabetes), whereas the kappa value was lowest for rheumatoid arthritis (0.21) and highest for diabetes (0.88). Sociodemographic variables were demonstrated to be significantly associated with total agreement for all diseases, with sex, age and educational level exhibiting the strongest associations. However, the directions of the associations were inconsistent across diseases. CONCLUSION: Overall, self-reported data were accurate in identifying individuals without the specific disease (ie, specificity and NPV). However, sensitivity, PPV and kappa varied greatly between diseases. These findings should be considered when interpreting similar results from surveys.

Evaluating the Effects of Denmark's New Tobacco Control Act on Young People's Use of Nicotine Products: A Study Protocol of the §SMOKE Study.

(1) Background: In December 2020, a broad majority of political parties in Denmark agreed on a new tobacco control act. In addition, price increases on tobacco in 2020 and 2022 became part of the Danish Finance Act. This study protocol describes the study "§SMOKE-A Study of Tobacco, Behavior, and Regulations" designed to monitor and evaluate the implementation and effect of the new strengthened tobacco control acts. The overall aim is to monitor tobacco use among young people before, during, and after implementation of the new tobacco control legislation, including an increased price on tobacco, a ban on point-of-sale tobacco displays, and plain packaging. Subgoals are to monitor overall use of nicotine products, attitudes, and norms. (2) Methods: This study is designed as a five-year impact evaluation with repeated cross-sectional survey data collections. The baseline survey was conducted before implementing an increased price on tobacco, the first step in the new legislation, initiated 1 April 2020. Study participants (n = 37,500) were a random sample of individuals living in Denmark aged 15 to 29 years. (3) Conclusions: This study examines the impact of the new strengthened tobacco control legislation in Denmark from 2020 to 2025. The findings of this study are relevant to other countries facing implementation of similar measures to explore intended and unintended consequences of the legislation and help to identify how the legislation could be further improved.

Patterns of Perceived Indoor Environment in Danish Homes.

The indoor environment is composed of several exposures existing simultaneously. Therefore, it might be useful to combine exposures into common combined measures when used to assess the association with health. The aim of our study was to identify patterns of the perceived indoor environment. Data from the Danish Health and Morbidity Survey in the year 2000 were used. The perceived indoor environment was assessed using a questionnaire (e.g., annoyances from noise, draught, and stuffy air; 13 items in total). Factor analysis was used to explore the structure of relationships between these 13 items. Furthermore, groups of individuals with similar perceived indoor environment were identified using latent class analysis. A total of 16,688 individuals ≥16 years participated. Their median age was 46 years. Four factors were extracted from the factor analysis. The factors were characterized by: (1) a mixture of items, (2) temperature, (3) traffic, and (4) neighbor noise. Moreover, three groups of individuals sharing the same perception of their indoor environment were identified. They were characterized by: a low (n = 14,829), moderate (n = 980), and large number of annoyances (n = 879). Observational studies need to take this correlation and clustering of perceived annoyances into account when studying associations between the indoor environment and health.

Use of Tobacco and Nicotine Products among Young People in Denmark-Status in Single and Dual Use.

Lots of new tobacco or nicotine products are being launched, e.g., e-cigarettes and smokeless tobacco, which appeal especially to the youngest part of the population. For example, the use of smokeless tobacco among Danish youth rose from approx. 2% in 2010 to 9% in 2020. Hence, there is an urgent need to follow and intervene against youth tobacco or nicotine product use. This study explored the current use of cigarettes, e-cigarettes, heated tobacco, and smokeless tobacco among Danish 15- to 29-year-olds. Further, we examined the concurrent use of two products or more. We used a nationwide survey conducted among 15- to 29-year-olds in February and March 2020. Overall, approx. 35,700 individuals received the questionnaire of which 35.5% responded (n = 13,315). One out of five (20.1%) smoked cigarettes, half of them daily, the other half occasionally. About one in twenty (3.9%) used e-cigarettes (daily or occasionally), and more than one in three (31.6%) had tried e-cigarettes. The use of heated tobacco among Danish youth is still relatively limited (0.3%). In comparison, about 9% used smokeless tobacco (daily or occasionally). Overall, 27.0% stated that they use at least one type of tobacco or nicotine product, while 5.6% used more than one product. Monitoring tobacco-related behavior in youth provides extremely important information for, e.g., policymakers and health professionals.

The impact of non-response weighting in health surveys for estimates on primary health care utilization.

BACKGROUND: Low response rates in health surveys may affect the representativeness and generalizability of results if non-response is systematically related to the indicator of interest. To account for such potential bias, weighting procedures are widely used with an overall aim to obtain less biased estimates. The aim of this study was to assess the impact of applying calibrated weights on prevalence estimates of primary health care utilization among respondents compared to the entire sample of a representative Danish survey of adults aged ≥16 years. METHODS: Registry-based 1-year prevalence data on health care utilization of chiropractor/physiotherapist, dentist and psychologist in 2016 were linked to the entire sample (n = 312 349), including respondents (n = 183 372), from the Danish National Health Survey in 2017. Calibrated weights, which applied information on e.g. sex, age, ethnic background, education and overall health service use were used to assess their impact on prevalence estimates among respondents. RESULTS: Across all included types of health care, weighting for non-response decreased prevalence estimates among respondents, which resulted in less biased estimates. For example, the overall 1-year prevalence of chiropractor/physiotherapist, dentist and psychologist utilization decreased from 19.1% to 16.9%, 68.4% to 62.5% and 1.9% to 1.8%, respectively. The corresponding prevalence in the entire sample was 16.5%, 59.4% and 1.7%. CONCLUSIONS: Applying calibrated weights to survey data to account for non-response reduces bias in primary health care utilization estimates. Future studies are needed to explore the possible impact of weighting on other health estimates.

Motivation to Reduce Drinking and Engagement in Alcohol Misuse Treatment in Alcohol-Related Liver Disease: A National Health Survey.

INTRODUCTION: The study aim was to identify predictors of motivation to reduce alcohol consumption and whether motivation predicts engagement in alcohol misuse treatment in alcohol-related liver disease (ALD). METHODS: Data from health surveys and health-care registries were combined. RESULTS: Of 674 patients with ALD, 65% consumed alcohol. Recent hospital admission and severe alcohol problems were associated with motivation to reduce alcohol consumption. Two-year probability for engagement in misuse treatment was 29% for patients with motivation to reduce alcohol consumption versus 6.5% for patients without motivation. DISCUSSION: ALD patients with recent hospital admission were more motivated to cut down alcohol consumption, and motivation predicted engagement in alcohol misuse treatment. This insight can help us target brief interventions.

The Danish National Health Survey: Study design, response rate and respondent characteristics in 2010, 2013 and 2017.

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.

Mental health and the risk of negative social life events: A prospective cohort study among the adult Danish population.

Background: The consequences of poor mental health on morbidity and mortality are well established. However, studies prospectively examining the consequences on social life events are lacking. This study prospectively examines the risk of various social life events (educational attainment, employment status, marital status and parenthood) defined in administrative registers by mental health status at baseline defined by the MCS-12 in the Danish adult population. Methods: The analysis is based on data from the Danish National Health Survey 2010. A total of 177,639 individuals completed the questionnaire (59.5% of the sample). MCS-12 was used to categorise participants according to mental health status (poor, moderate and good). Survey data were linked to administrative registers at the individual level and followed for a minimum of 4 years. Cox proportional hazards models were used to prospectively examine the risk of various social life events according to mental health status at baseline. Results: Individuals with poor mental health and, to a certain degree, individuals with moderate mental health were less likely to experience positive life events such as progression in educational level, getting married, being employed and becoming a parent and were more likely to experience negative life events such as becoming unemployed and divorced/widowed. Conclusions: Mental health status is associated with educational attainment, employment status, marital status and parenthood. These results add to a growing body of evidence indicating that poor mental health is associated with substantial societal-level impairments that should be taken into consideration when making decisions regarding allocation of treatment and research resources.

The Danish National Youth Study 2019: study design and participant characteristics.

AIM: To present the study design, study population and questionnaire content of the Danish National Youth Study 2019, and to describe the differences between participants and non-participants regarding demographic and socioeconomic characteristics. METHOD: The Danish National Youth Study 2019 is a nationwide web-survey among high school students in Denmark. Data was collected from January to April 2019 through a self-administered questionnaire in the classroom. The questionnaire included 120 questions on, for example, physical and mental health, health behaviour and well-being. Data collection took place at 50 general high schools, 32 preparatory high schools, 15 commercial high school and 19 technical high schools. RESULTS: A total of 29,086 students participated (20,287 general high school students, 2,113 preparatory higher school students, 4027 commercial high school students and 2659 technical high school students) corresponding to 66% of the students in the 88 participating schools (31% of invited schools). Among students, 55% were female and the mean age was 17.8 years. Participants were more likely to be female, to be younger, to be of Danish origin, and have family disposable income in the highest quartile compared to non-participants. CONCLUSIONS: The Danish National Youth Study 2019 contributes to knowledge on high school students' health, health behaviour and well-being that can support health planning and prioritizing, through identification of specific risk groups at both local and national level. The study also offers great opportunities for future research as it provides possibility of linkage to various Danish national registers.

History of healthcare use and disease burden in older adults with different levels of alcohol use. A register-based cohort study.

BACKGROUND: Only a minority of individuals with problematic alcohol use ever seek alcohol treatment. Knowledge of general help-seeking behavior in the healthcare system can identify possibilities for prevention and intervention. METHOD: The current study describes healthcare use, burden of disease, and prior morbidities over a 15-year period by current alcohol use behavior among Danish adults aged 60-70. The Danish National Health Survey 2013 and the baseline assessment of the Elderly Study (2014-2016) were linked to Danish national registers to collect annual information on healthcare use and morbidity for the 15 years prior to inclusion. Participants from the 3 largest Danish municipalities were divided into 4 groups with varying drinking patterns and no recent treatment [12-month abstinent (n = 691), low-risk drinkers (n = 1978), moderate-risk drinkers (n = 602), and high-risk drinkers (n = 467)], and a group of treatment-seeking individuals with a 12-month DSM-5 alcohol use disorder (AUD; n=262). Negative binomial regression models were utilized to compare rates of healthcare use and logistic regressions were used to compare odds of diagnoses. RESULTS: Low-, moderate-, and high-risk drinkers had similar rates of past healthcare utilization (low-risk mean yearly number of contacts for primary care 7.50 (yearly range 6.25-8.45), outpatient care 0.80 (0.41-1.32) and inpatient care 0.13 (0.10-0.21)). Higher rates were observed for both the 12-month abstinent group (adjusted RR = 1.16-1.26) and the group with AUD (ARR = 1.40-1.60) compared to the group with low-risk alcohol consumption. Individuals with AUD had higher odds of previous liver disease (adjusted OR = 6.30), ulcer disease (AOR = 2.83), and peripheral vascular disease (AOR 2.71). Twelve-month abstinence was associated with higher odds of diabetes (AOR = 1.97) and ulcer disease (AOR = 2.10). CONCLUSIONS: Looking back in time, we found that older adults had regular healthcare contacts, with those who received treatment for AUD having had the highest contact frequency and prevalence of alcohol-related diseases. Thus, healthcare settings are suitable locations for efforts at AUD prevention and intervention.

Meat consumption, stratified by dietary quality, and risk of heart disease.

Associations between meat consumption and heart disease have been assessed in several studies, but it has been suggested that other dietary factors influence these associations. The aim of the present study was to assess whether meat consumption is associated with ischaemic heart disease (IHD), and if the association is modified by dietary quality. The analyses were based on the cohort of adult participants in the Danish National Survey on Diet and Physical Activity in 2000-2002, 2003-2008 and 2011-2013. From these surveys, information on meat consumption and dietary quality was extracted. The cohort was followed in national registers to identify incident IHD. Associations were estimated using Cox regression analyses adjusting for socio-demographic and lifestyle factors. Analyses of associations between meat consumption and IHD stratified by dietary quality were subsequently evaluated. Among the 8007 participants, the median follow-up was 9·8 years and 439 cases of IHD were recorded. The results suggested a trend between consumption increments of 100 g/d of red meat (hazard ratio (HR) = 1·23; 95 % CI 0·99, 1·53) or of 50 g/d of processed meat (HR = 1·09; 95 % CI 0·93, 1·29) and higher risk of IHD. The trends were, however, not statistically significant. Stratification by dietary quality did not suggest that associations between meat consumption and risk of IHD were modified by dietary quality. This population-based cohort study with detailed dietary information suggested a trend with higher meat consumption being associated with higher risk of IHD, but the association was not statistically significant. Results did not indicate that dietary quality modifies such associations.

Health-Related Quality of Life in Patients with Philadelphia-Negative Myeloproliferative Neoplasms: A Nationwide Population-Based Survey in Denmark.

Previous studies have clarified that many patients with Philadelphia-negative myeloproliferative neoplasms (MPNs) have burdensome symptom profiles and accordingly impaired functioning and quality of life (QoL). In Denmark, all MPN patients are affiliated with public hospitals and because of a healthcare system financed by taxpayers these patients do not have any financial costs related to the hematological disease. Diagnoses are recorded for all patients in hospitals, and diagnosis codes are communicated to the National Patient Register (NPR). Owing to this, it was possible to contribute to the elucidation of Philadelphia-negative MPN patients' health-related quality of life (HRQoL), by conducting a nationwide, population-based, cross-sectional HRQoL survey of these patients with cost-free access to the best available, suitable medical treatment. The survey contained validated questionnaires covering functioning, symptom burden, symptom profile, QoL, and additional questions on lifestyle. Information on comorbid diagnoses was obtained from the NPR. The participants' HRQoL was compared to the general population. Moreover, differences in HRQoL across essential thrombocythemia, polycythemia vera, myelofibrosis, and unclassifiable MPN participants were investigated, adjusted for age, sex, comorbidity, and lifestyle. To the best of our knowledge this is the first survey of HRQoL in patients with unclassifiable MPN. A total of 2228 Philadelphia-negative MPN patients participated. The participants reported their HRQoL to be inferior to the general population, but the difference was minor. The differences in HRQoL across groups of participants with different MPN subtypes were subtle. Fatigue and sexual problems were prevalent and burdensome. Overall, participants reported a slightly healthier lifestyle compared to the general population.

[Has the general health and well-being among the elderly Danes stagnated from 2010 to 2017?]

As the Danish population is ageing, there is an increasing need for investigating the trends in health and well-being among elderly. Based on a new report from the Danish Health Authority, health professionals and the media reported, that health and well-being among elderly had not improved in 2010-2017. In this review it is argued, that the report does not justify this conclusion because of the following four issues: Other Danish studies show a progress and these studies have not been taken into consideration, cognitive abilities are not included, different health measures in the report showed divergent trends, and some measures indicate methodological weaknesses.

Twenty Years Socioeconomic Trajectories in Older Adults with Varying Alcohol Use: A Register-Based Cohort Study.

AIMS: The objective of this paper was to examine 20-year trends of the socioeconomic status (SES) measures income and employment and their association with current alcohol use behaviors in Danish adults aged 60-70. METHODS: Data from The Danish National Health Survey 2013 and the baseline assessment of the Elderly Study (2013-2016) were combined to form four groups from the general population with various drinking patterns, but with no recent treatment for alcohol use disorder (AUD), and one group seeking treatment: Abstinent (n = 691), low- (n = 1978), moderate- (n = 602), and high-risk (HR) drinkers (n = 467), and DSM-5 AUD seeking treatment (n = 262). For all groups, Danish national register data were linked at the individual level obtain find annual information on income and employment during the 20 years prior to interview. Mixed effects models were utilized to model trajectories of income and employment for the five groups. RESULTS: Lower income and employment status was observed from middle-aged adulthood when comparing 12-month abstinence or AUD to individuals with low or moderate alcohol consumption. At the end of the study period, moderate-risk drinkers experienced an increase, and HR drinkers a decrease, in income and rate of employment relative to the low-risk drinkers. CONCLUSIONS: Alcohol use behaviors observed in older adults are related to distinct long-term trajectories regarding income and employment status, which are observable already in middle-aged adulthood.
