Incidence of atrial fibrillation and flutter in Denmark in relation to country of origin: a nationwide register-based study.

BACKGROUND: Atrial fibrillation and flutter (AF) is the most common sustained arrhythmia with an increasing prevalence in Western countries. However, little is known about AF among immigrants compared to non-immigrants. AIM: To examine the incidence of hospital-diagnosed AF according to country of origin. METHOD: Immigrants were defined as individuals born outside Denmark by parents born outside Denmark. AF was defined as first-time diagnosis of AF. All individuals were followed from the age of 45 years from 1998 to 2017. The analyses were adjusted for sex, age, comorbidity, contact with the general practitioner and socioeconomic variables. Adjustment was conducted using standardised morbidity ratio weights, standardised to the Danish population in a marginal structural model. RESULTS: The study population consisted of 3,489,730 Danish individuals free of AF and 108,914 immigrants free of AF who had emigrated from the 10 most represented countries. A total of 323,005 individuals of Danish origin had an incident hospital diagnosis of AF, among the immigrants 7,300 developed AF. Adjusted hazard rate ratios (HRRs) of AF for immigrants from Iran (0.48 [95%CI:0.35;0.64]), Turkey (0.74 [95%CI:0.67;0.82]) and Bosnia-Herzegovina (0.42 [95%CI:0.22;0.79]) were low compared with Danish individuals. Immigrants from Sweden, Germany and Norway had an adjusted HRR of 1.13 [95%CI:1.03;1.23], 1.12 [95%CI:1.05;1.18] and 1.11 [95%CI:1.03;1.21], respectively (Danish individuals as reference). CONCLUSIONS: Substantial variation in the incidence of hospital-diagnosed AF according to country of origin was observed. The results may reflect true biological differences but could also reflect barriers to AF diagnosis for immigrants. Further efforts are warranted to determine the underlying mechanisms.

Development and inter-rater reliability of a simple prehospital mobility score for use in emergency patients.

BACKGROUND: Mobility assessment enhances the ability of vital sign-based early warning scores to predict risk. Currently mobility is not routinely assessed in a standardized manner in Denmark during the ambulance transfer of unselected emergency patients. The aim of this study was to develop and test the inter-rater reliability of a simple prehospital mobility score for pre-hospital use in ambulances and to test its inter-rater reliability. METHOD: Following a pilot study, we developed a 4-level prehospital mobility score based of the question"How much help did the patient need to be mobilized to the ambulance trolley". Possible scores were no-, a little-, moderate-, and a lot of help. A cross-sectional study of inter-rater agreement among ambulance personnel was then carried out. Paramedics on ambulance runs in the North- and Central Denmark Region, as well as The Fareoe Islands, were included as a convenience sample between July 2020-May 2021. The simple prehospital mobility score was tested, both by the paramedics in the ambulance and by an additional observer. The study outcomes were inter-rater agreements by weighted kappa between the paramedics and between observers and paramedics. RESULTS: We included 251 mobility assessments where the patient mobility was scored. Paramedics agreed on the mobility score for 202 patients (80,5%). For 47 (18.7%), there was a deviation of one between scores, in two (< 1%) there was a deviation of two and none had a deviation of three (Table 1). Inter-rater agreement between paramedics in all three regions showed a kappa-coefficient of 0.84 (CI 95%: 0.79;0.88). Between observers and paramedics in North Denmark Region and Faroe Islands the kappa-coefficient was 0.82 (CI 95%: 0.77;0.86). CONCLUSION: We developed a simple prehospital mobility score, which was feasible in a prehospital setting and with a high inter-rater agreement between paramedics and observers.

Socioeconomic differences in expected discomfort from colonoscopy and colon capsule endoscopy.

Individual income and educational level are associated with participation rates in colorectal cancer screening. We aimed to investigate the expected discomfort from the endoscopic diagnostic modalities of colonoscopy and colon capsule endoscopy in different socioeconomic groups as a potential barrier for participation. In a randomized clinical trial within the Danish colorectal cancer screening program, we distributed questionnaires to 2031 individuals between August 2020 and December 2022 to investigate the expected procedural and overall discomfort from investigations using visual analogue scales. Socioeconomic status was determined by household income and educational level. Multivariate continuous ordinal regressions were performed to estimate the odds of higher expected discomfort. The expected procedural and overall discomfort from both modalities were significantly higher with increasing educational levels and income, except for procedural discomfort from colon capsule endoscopy between income quartiles. The odds ratios for higher expected discomfort increased significantly with increasing educational level, whereas the differences between income groups were less substantial. Bowel preparation contributed most to expected discomfort in colon capsule endoscopy, whereas in colonoscopy, the procedure itself was the largest contributor. Individuals with prior experiences of colonoscopy reported significantly lower expected overall but not procedural discomfort from colonoscopy. The threshold for acceptable discomfort between subgroups is unknown, but the expected discomfort in colon capsule endoscopy and colonoscopy was higher in higher socioeconomic subgroups, suggesting that expected discomfort is not a significant contributor to the inequalities in screening uptake.

Time trends in income-related disparity in incidence of acute coronary syndrome.

BACKGROUND: Higher incidence of acute coronary syndrome (ACS), among those with lower income, has been recognized in the most recent decades. Still, there is a paucity of data on temporal changes. This study aims to investigate 20-year time trends in income-related disparity in the incidence of ACS in Denmark. METHODS: This Population-based repeated cross-sectional study included all patients with first-time ACS, aged ≥20 years, registered in the Danish National Patient Registry 1998-2017. Aggregated sociodemographic data for the Danish population was accessed from Statistics Denmark. Yearly incidence rates (IR) and incidence rate ratios (IRR), with the highest-income quartile as a reference, were standardized using cell-specific personal equivalent income according to year, sex and age group with 95% confidence intervals. Interaction analysis was executed for differences in IR of ACS between the lowest- and highest-income quartile over time. RESULTS: A total of 220 070 patients hospitalized with ACS from 1998 to 2017 were identified. The yearly standardized ACS IRs decreased in all income quartiles. However, the IR remained higher in the lowest-income quartile compared to the highest for both men [1998: IRR 1.45 (95% confidence interval, CI 1.39-1.52) and 2017: 1.47 (1.40-1.54)] and women [1998: IRR 1.73 (1.64-1.82) and 2017: 1.76 (1.65-1.88)]. Interaction analysis showed that over the period the difference in IR between the lower- and the highest-income quartile decreased with 1-5 ACS cases per 100 000 person-year. CONCLUSION: Income-related disparity in the incidence of ACS was present in Denmark between 1998 and 2017. Despite a marked overall decrease in the yearly ACS incidence, the extent of income-related disparity remained unchanged.

Decision on non-conveyance of patients suspected of COVID-19 in a novel arrangement with assessment visits by paramedics at home.

BACKGROUND: During the first weeks of the outbreak of the coronavirus disease 2019 (COVID-19), the North Denmark emergency medical services authorised paramedics to assess patients suspected of COVID-19 at home, and then decide if conveyance to a hospital was required. The aim of this study was to describe the cohort of patients who were assessed at home and their outcomes in terms of subsequent hospital visits and short-term mortality. METHODS: This was a historical cohort study in the North Denmark Region with consecutive inclusion of patients suspected of COVID-19 who were referred to a paramedic's assessment visit by their general practitioner or an out-of-hours general practitioner. The study was conducted from 16 March to 20 May 2020. The outcomes were the proportion of non-conveyed patients who subsequently visited a hospital within 72 hours of the paramedic's assessment visit and mortality at 3, 7 and 30 days. Mortality was estimated using a Poisson regression model with robust variance estimation. RESULTS: During the study period, 587 patients with a median age of 75 (IQR 59-84) years were referred to a paramedic's assessment visit. Three of four patients (76.5%, 95% CI 72.8;79.9) were non-conveyed, and 13.1% (95% CI 10.2;16.6) of the non-conveyed patients were subsequently referred to a hospital within 72 hours of the paramedic's assessment visit. Within 30 days from the paramedic's assessment visit, mortality was 11.1% [95% CI 6.9;17.9] among patients directly conveyed to a hospital and 5.8% [95% CI 4.0;8.5] among non-conveyed patients. Medical record review revealed that deaths in the non-conveyed group had happened among patients with 'do-not-resuscitate' orders, palliative care plans, severe comorbidities, age ≥ 90 years or nursing home residents. CONCLUSIONS: The majority (87%) of the non-conveyed patients did not visit a hospital for the following three days after a paramedic's assessment visit. The study implies that this newly established prehospital arrangement served as a kind of gatekeeper for the region's hospitals in regard to patients suspected of COVID-19. The study also demonstrates that implementation of non-conveyance protocols should be accompanied by careful and regular evaluation to ensure patient safety.

Validation of retail food outlet data from a Danish government inspection database.

BACKGROUND: Globally, unhealthy diet is one of the leading global risks to health, thus it is central to consider aspects of the food environment that are modifiable and may enable healthy eating. Food retail data can be used to present and facilitate analyses of food environments that in turn may direct strategies towards improving dietary patterns among populations. Though food retail data are available in many countries, their completeness and accuracy differ. METHODS: We applied a systematically name-based procedure combined with a manual procedure on Danish administrative food retailer data (i.e. the Smiley register) to identify, locate and classify food outlets. Food outlets were classified into the most commonly used classifications (i.e. fast food, restaurants, convenience stores, supermarkets, fruit and vegetable stores and miscellaneous) each divided into three commonly used definitions; narrow, moderate and broad. Classifications were based on branch code, name, and/or information on the internal and external appearance of the food outlet. From ground-truthing we validated the information in the register for its sensitivity and positive predictive value. RESULTS: In 361 randomly selected areas of the Capital region of Denmark we identified a total of 1887 food outlets compared with 1861 identified in the register. We obtained a sensitivity of 0.75 and a positive predictive value of 0.76. Across classifications, the positive predictive values varied with highest values for the moderate and broad definitions of fast food, convenience stores and supermarkets (ranging from 0.89 to 0.97). CONCLUSION: Information from the Smiley Register is considered to be representative to the Danish food environment and may be used for future research.

Association of perceived work pace and physical work demands with occupational accidents: a cross-sectional study of ageing male construction workers in Denmark.

BACKGROUND: Occupational accidents continue to be a significant public health challenge worldwide. Construction workers in particular are at high risk of occupational accidents, and thus it is of major importance to identify possible predictors of occupational accidents among construction workers. We aimed to investigate the association between self-reported work pace and physical work demands and occupational accidents among ageing male construction workers in Denmark. METHODS: Data on perceived work pace, physical work demands, and occupational accidents was acquired from questionnaires sent to ageing construction workers in Denmark in 2016 as part of the ALFA project (ALdring og Fysisk Arbejde; Ageing and Physical Work). A sample of 1270 Danish male construction workers above 50 years of age was included in the present study. Multiple logistic regression models were applied, with adjustments for age, smoking, body mass index, musculoskeletal disorders, occupation, work experience, and support at work. RESULTS: Of 1270 construction workers, 166 (13.1%) reported an occupational accident within the last 12 months. There was no significant association between perceived work pace and occupational accidents, but physical work demands were associated with higher odds for occupational accidents, with an odds ratio of 2.27 (95% confidence interval 1.26-4.10) for medium physical work demands and 2.62 (95% confidence interval 1.50-4.57) for high physical work demands. CONCLUSIONS: Ageing male construction workers with high physical work demands had statistically significant higher odds of having an occupational accident. By contrast, perceived work pace was not associated with occupational accidents in this large cross-sectional study.

Chronic post-operative opioid use after open cardiac surgery: A Danish population-based cohort study.

BACKGROUND: Knowledge of chronic opioid use after cardiac surgery is sparse. We therefore aimed to describe the proportion of new chronic post-operative opioid use after open cardiac surgery. METHODS: We used prospectively registered data from a national prescription registry and a clinical registry of 29 815 first-time cardiac surgeries from three Danish university hospitals. Data collection spanned from 2003 to 2016. The main outcome was chronic post-operative opioid use, defined as at least one opioid dispensing in the fourth post-operative quarter. Data were assessed for patient-level predictors of chronic post-operative opioid use, including pre-operative opioid use, opioid use at discharge, comorbidities, and procedural related variables. RESULTS: The overall proportion of post-operative opioid use was 10.6% (95% CI: 10.2-10.9). The proportion of new chronic post-operative opioid use was 5.7% (95% CI: 5.5-6.0) among pre-operative opioid naïve patients. The corresponding proportions among patients, who pre-operatively used low or high dose opioid (1-500 mg or > 500 mg cumulative morphine equivalent opioid), were 68.3% (95% CI: 66.1-70.4) and 76.3% (95% CI: 74.0-78.5) respectively. Risk factors associated with new chronic post-operative opioid use included: female gender, underweight and obesity, pre-operative comorbidities, acute surgery, ICU-time > 1 day, and post-operative complications. Strongest predictor of chronic post-operative opioid use was post-discharge use of opioid within one month after surgery (odds ratio 3.3, 95% CI: 2.8-4.0). CONCLUSION: New chronic post-operative opioid use after open cardiac surgery is common. Focus on post-discharge opioid use may help clinicians to reduce rates of new chronic opioid users.

Retirement status and frailty: a cross-sectional study of the phenotype of manual workers aged 50-70 years.

BACKGROUND: The frailty phenotype is predictive of mortality and has been identified in the working population. This cross-sectional study aimed to investigate the prevalence of frailty and individual frailty symptoms among active and retired Danish manual workers and to delineate the relationship between frailty and lifestyle factors. METHODS: Manual workers aged 50-70 years answered questions relating to the Fried criteria for frailty (weight loss, exhaustion, slowness, weakness and inactivity). Only men were included in the analyses and respondents were stratified according to work status: active workers (n = 1555), early retirees (n = 289) and workers retired at or after normal pension age (n = 291). Associations between pre-frailty/frailty, work status and various lifestyle factors were estimated using binomial logistic regression. RESULTS: Overall, the prevalence of pre-frailty (one or two symptoms) and frailty (three or more symptoms) was 33.3% and 1.5%, respectively. Those who had retired early were more likely to be pre-frail/frail compared with active workers (odds ratio 2.20, 95% CI 1.61-3.01). Exhaustion was the most prominent symptom reported by 22.2% of active workers, 34.6% of early retirees and 16.5% of workers retired at normal retirement age. Lifestyle factors including obesity, physical inactivity and smoking but not alcohol intake were associated with pre-frailty/frailty. CONCLUSION: Symptoms of frailty are identifiable and present among both active and retired manual workers. Data suggest discrepancies among Danish manual workers, with some having unhealthy lifestyles and being more prone to develop pre-frailty and frailty already in their sixth decade of life.

Impact of plasma potassium normalization on short-term mortality in patients with hypertension and hypokalemia or low normal potassium.

BACKGROUND: Hypokalemia is common in patients treated with antihypertensive drugs, but the impact of correcting hypokalemia is insufficiently studied. We examined the consequences of hypokalemia and borderline hypokalemia correction in patients with hypertension. METHODS: We identified 8976 patients with hypertension and plasma potassium concentrations ≤3.7 mmol/L within 100 days from combination antihypertensive therapy initiation. The first measurement between 6 and 100 days after the episode with potassium ≤3.7 mmol/L was retained. We investigated all-cause and cardiovascular mortality within 60-days from the second potassium measurement using Cox regression. Mortality was examined for seven predefined potassium intervals derived from the second measurement: 1.5-2.9 mmol/L (n = 271), 3.0-3.4 mmol/L (n = 1341), 3.5-3.7 (n = 1982) mmol/L, 3.8-4.0 mmol/L (n = 2398, reference), 4.1-4.6 mmol/L (n = 2498), 4.7-5.0 mmol/L (n = 352) and 5.1-7.1 mmol/L (n = 134). RESULTS: Multivariable analysis showed that potassium concentrations 1.5-2.9 mmol/L, 3.0-3.4 mmol/L, 4.7-5.0 mmol/L and 5.1-7.1 mmol/L were associated with increased all-cause mortality (HR 2.39, 95% CI 1.66-3.43; HR 1.36, 95% CI 1.04-1.78; HR 2.36, 95% CI 1.68-3.30 and HR 2.62, 95% CI 1.73-3.98, respectively). Potassium levels <3.0 and > 4.6 mmol/L were associated with increased cardiovascular mortality. The adjusted standardized 60-day mortality risks in the seven strata were: 11.7% (95% CI 8.3-15.0%), 7.1% (95% CI 5.8-8.5%), 6.4% (95% CI 5.3-7.5%), 5.4% (4.5-6.3%), 6.3% (5.4-7.2%), 11.6% (95% CI 8.7-14.6%) and 12.6% (95% CI 8.2-16.9%), respectively. CONCLUSIONS: Persistent hypokalemia was frequent and associated with increased all-cause and cardiovascular mortality. Increase in potassium to levels > 4.6 mmol/L in patients with initial hypokalemia or low normal potassium was associated with increased all-cause and cardiovascular mortality.

First-line treatment of pelvic organ prolapse and discontinuation of pessary treatment.

INTRODUCTION: The primary objective of this study was to investigate the percentages of women choosing watchful waiting, pessary use or surgery as first-line treatment of pelvic organ prolapse (POP). Second, the rate and cause of discontinuation of pessary use were investigated. METHODS: A retrospective chart review was conducted on 794 patients referred with POP at a Danish tertiary center for urogynecology at Aalborg University Hospital between 1 January 2014 and 31 December 2015. The following data were registered: age, BMI, previous use of a pessary, total number of births, vaginal births, cesarean sections, previous hysterectomy, prolapse surgery and incontinence surgery, smoking, menopause, sexual status and POP-Q stage in the three vaginal compartments. Pessary treatments were evaluated after 3 months. Additional visits, reason for discontinuation and secondary treatment were noted. RESULTS: First-line treatment was surgery in 50%, watchful waiting in 33% and pessary use in 17% of patients. Characteristics associated with choosing surgery instead of a pessary were age < 65 years, previous prolapse surgery, prolapse in the anterior or posterior compartment, and POP-Q stage > 2. Characteristics associated with choosing watchful waiting instead of a pessary were age < 65 years and prolapse in the posterior compartment. A total of 33% discontinued pessary treatment within the first 3 months. Discontinuation was associated with age < 65 years, previous hysterectomy and pelvic surgery, and additional visits. Expulsion of the pessary and pain/discomfort were the main causes of discontinuation. CONCLUSION: This study showed that 50% of patients referred with POP were treated with conservative treatment (watchful waiting and pessary) and thus more women could probably be treated in primary care.

Associations of health literacy with socioeconomic position, health risk behavior, and health status: a large national population-based survey among Danish adults.

BACKGROUND: Health literacy concerns the ability of citizens to meet the complex demands of health in modern society. Data on the distribution of health literacy in general populations and how health literacy impacts health behavior and general health remains scarce. The present study aims to investigate the prevalence of health literacy levels and associations of health literacy with socioeconomic position, health risk behavior, and health status at a population level. METHODS: A nationwide cross-sectional survey linked to administrative registry data was applied to a randomly selected sample of 15,728 Danish individuals aged ≥25 years. By the short form HLS-EU-Q16 health literacy was measured for the domains of healthcare, disease prevention, and health promotion. Adjusted multinomial logistic regression analyses were used to estimate associations of health literacy with demographic and socioeconomic characteristics, health risk behavior (physical activity, smoking, alcohol consumption, body weight), and health status (sickness benefits, self-assessed health). RESULTS: Overall, 9007 (57.3%) individuals responded to the survey. Nearly 4 in 10 respondents faced difficulties in accessing, understanding, appraising, and applying health information. Notably, 8.18% presented with inadequate health literacy and 30.94% with problematic health literacy. Adjusted for potential confounders, regression analyses showed that males, younger individuals, immigrants, individuals with basic education or income below the national average, and individuals receiving social benefits had substantially higher odds of inadequate health literacy. Among health behavior factors (smoking, high alcohol consumption, and inactivity), only physical behavior [sedentary: OR: 2.31 (95% CI: 1.81; 2.95)] was associated with inadequate health literacy in the adjusted models. The long-term health risk indicator body-weight showed that individuals with obesity [OR: 1.78 (95% CI: 1.39; 2.28)] had significantly higher odds of lower health literacy scores. Poor self-assessed health [OR: 4.03 (95% CI: 3.26; 5.00)] and payments of sickness absence compensation benefits [OR: 1.74 (95% CI: 1.35; 2.23)] were associated with lower health literacy scores. CONCLUSIONS: Despite a relatively highly educated population, the prevalence of inadequate health literacy is high. Inadequate health literacy is strongly associated with a low socioeconomic position, poor health status, inactivity, and overweight, but to a lesser extent with health behavior factors such as smoking and high alcohol consumption.

Understanding rapid infant weight gain prevention: a systematic review of quantitative and qualitative evidence.

BACKGROUND: Rapid infant weight gain (RIWG) is strongly related to childhood overweight and obesity, and prevention of RIWG is an approach to early years obesity prevention. This systematic review aimed to explore effectiveness, deliverers' and recipients' experiences of involvement, and key intervention components and processes of such prevention activities. METHODS: Key databases and websites were searched systematically for quantitative and qualitative studies covering intervention effectiveness, experiences with intervention involvement or process outcomes. After duplicate screening and quality assessment, papers were analyzed through narrative synthesis, thematic synthesis and intervention component analysis. RESULTS: Seven quantitative and seven qualitative studies were eligible for inclusion. Most intervention studies reported small, but significant results on infant weight gain. More significant results were measured on weight gain during the first compared with the second year of life. A weak evidence base made elaboration of the relationship between intervention effectiveness and content challenging. Home-delivered interventions may be more relevant for parents. Contextual factors, such as social norms, beliefs and professional identity should be considered during intervention development. Stakeholder involvement can be key to increase intervention acceptability and feasibility. CONCLUSIONS: The field of RIWG prevention is new and evolving, but more research is needed before further conclusions about intervention effectiveness and intervention content can be drawn. Future interventions should take parents, health professionals and other contextual needs into account to improve chances of success. More research on long-term effects on overweight and obesity is needed.

Health educational background as a predictor of non-participation in national colorectal cancer screening: A cross-sectional population study among 886,088 invited Danes.

Health information knowledge may affect attitude toward colorectal cancer screening, but the participation of health educated citizens are unknown. Therefore, we investigated non-participation in a sample of 886,088 invited participants, based on educational length, type, and level. Logistic regression analyses were conducted to estimate the odds of non-participation in Danish men and women based on educational type and length. Models were adjusted for age, income, marital status and immigration status. Information was derived from National registers. Men with long educational length level had increased odds of non-participation if their education was within the field of medicine/medical science (OR 1.87) or belonged to other long health educations, but not in nursing and health care, compared to other long educations after full model adjustment. Women with long educational length level had increased odds of non-participation if they were educated in the field of medicine/medical science (OR 1.47), whereas they had decreased odds in the fields of nursing and health care and other long health educations, compared to other long educations after full model adjustment. Men within short educational length level did not have different odds of nonparticipation, after full model adjustments, whereas women within short health educations were at increased odds in the youngest age group and at decreased odds in the eldest age group. Having an education in the field of medicine/medical science is associated with non-participation in colorectal cancer screening in Denmark 2014-2015. Opposite, an educational background in nursing and health care increased participation in women, but not in men.

The effects of reminders for colorectal cancer screening: participation and inequality.

PURPOSE: To investigate the effect of sending out reminders for colorectal cancer screening on socioeconomic and demographic inequalities in screening uptake. METHODS: All citizens aged 50-74 in Denmark are invited every 2 years for colorectal cancer screening. Non-participants receive an electronically distributed reminder. Data for these analyses were derived from national registers. Socioeconomic status was measured by income and educational level. Demographic variables included age, gender and marital status, and the analyses were stratified by immigration status. Logistic regression analyses were conducted to estimate the odds of non-participation for invited citizens and for reminded citizens divided by socioeconomic and demographic predictors. RESULTS: Of 763,511 native Danes invited for screening from 2014 to 2015, 387,116 (50.70%) participated after the initial invitation and 133,470 after receiving a reminder. Differences in participation were present in relation to all subgroups among both the invited citizens and reminded citizens. Differences persisted after full model adjustments with reductions for demographic variables. Odds ratio (OR) for non-participation in the eldest age group was 0.32 (95% CI, 0.32; 0.33) before and 1.11 (95% CI 1, 0.08; 1.14) after the reminder, compared to those under 55 years. OR for the 4th income quartile was 0.54 (95% CI, 0.53; 0.55) before and 0.44 (95% CI, 0.43; 0.45) after the reminder, compared to 1st quartile. CONCLUSIONS: Reminders increased the overall participation, and the inequalities in participation in relation to demographic factors were reduced after the distribution of reminders. The age differences were especially reduced. The inequalities in participation related to socioeconomic status were, however, slightly increased after reminder distribution.

Translation and validation of the International Consultation on Incontinence Questionnaire Vaginal Symptoms (ICIQ-VS): the Danish version.

INTRODUCTION: In the clinical evaluation of women with pelvic organ prolapse (POP), it is important to evaluate both objective and subjective presentations. The objective evaluation is done by gynecological examination, but the subjective presentation is more complex. The International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS) is an important tool for subjective evaluation, and a Danish version was developed. MATERIALS AND METHODS: The English version was translated into Danish in accordance with guidelines. Eight women underwent a semistructured interview showing no misunderstandings. Women with and without prolapse completed the questionnaire and underwent a Pelvic Organ Prolapse Quantification (POP-Q) examination. Three weeks later a retest was done. Women undergoing prolapse surgery completed the questionnaire 3 months postoperatively. RESULTS: Ninety-four women with and 98 without prolapse were included; 52 underwent surgery. Retest response rate was 88-95%. Mean time between test and retest was 24.5 and 92.2 days, respectively. Missing data ranged between 0 and 1%. Test-retest reliability was good to excellent (ICC 0.61-0.88) and internal consistency was acceptable (Cronbach's alpha 0.79-0.84). The questionnaire was excellent when distinguishing between women with and without prolapse (p < 0.001). Criterion validity (correlation between POP-Q stage and the questionnaire) was perfect (p < 0.001). Sensitivity to change was excellent for vaginal symptom score and quality of life (p < 0.001) but not for sexual matters (p = 0.059). CONCLUSIONS: The Danish version of ICIQ-VS was successfully translated and can be a valuable tool for prolapse research and daily evaluation of patients.

The impact of prior psychiatric medical treatment on return to work after a diagnosis of breast cancer: A registry based study.

Purpose: Breast cancer and psychiatric disorders negatively impact work life, both positively associated with unemployment and early retirement. Our purpose was to assess whether being prescribed psychiatric medication, 2-4 yrs prior to a diagnosis of breast cancer, could impact the likelihood of returning to work after cancer therapy. Methods: 16,868 self-supporting women, diagnosed with breast cancer in Denmark from 2000 to 2012, were identified from a population-based clinical database, then cross-referenced to data held for psychiatric medication usage, sociodemographics, and labour-market participation. The association between historic psychiatric medication and return to work was estimated using a modified Poisson regression model. 'Return to work' was defined as being self-supporting one year after diagnosis of breast cancer. Results: 16% of our cohort had used psychiatric medical treatment 2-4 years before their diagnosis. Sixty-three per cent of these individuals had returned to work one year later, compared to 69% of the patient group with no prior history of using psychiatric medication treatments. In the fully adjusted model, prior use of psychiatric medication diminished the likelihood of returning to work one year after cancer diagnosis (RR = 0.91 (0.87-0.94)). High income and older age were positively associated with returning to work; negative correlates included those related to disease severity. Conclusions: Historic use of psychiatric medication provoked a minor, although statistically significant reduction in the resumption of working life one year after a diagnosis of breast cancer. Implications for cancer survivors: Although historic use of psychiatric medication may incur a minor effect on working life, further research is needed on the long-term social consequences for sub-groups.

Infancy weight gain, parental socioeconomic position, and childhood overweight and obesity: a Danish register-based cohort study.

BACKGROUND: Rapid infant weight gain (RIWG) is a very strong predictor of childhood overweight and obesity (COO). Socioeconomic position (SEP) is also related to the risk of COO and parents of different SEP may differ in their reaction to accelerated infant weight gain. Together this could lead to differences in how weight gain and COO risk relate across SEP. This study aimed to analyse possible interaction of SEP and RIWG on COO risk. METHODS: A register-based longitudinal cohort study followed 19,894 healthy, term infants, born in Denmark between December 2011 and May 2015. Logistic regression models were used to estimate odds ratios (OR) of COO risk at 2 years (22-26 months) of age with 95% confidence intervals (95% CI) for categories of infancy weight gain based on changes in weight-for-age z-scores between 0 and 8-10 months of age (slow (<- 0.67), mean (- 0.67-0.67), rapid (> 0.67-1.34) and very rapid (> 1.34)). Possible multiplicative and additive interaction of SEP (based on household income and maternal education) on the relationship between infancy weight gain and COO were analysed. RESULTS: In total, 19.1 and 15.1% experienced rapid or very rapid weight gain, respectively, and 1497 (7.5%) children were classified with COO at follow-up. These prevalences were higher in those with lower levels of SEP. Adjusted OR for COO were 3.09 (95% CI [2.66-3.59]) and 7.58 (95% CI [6.51-8.83]) for rapid and very rapid weight gain, respectively, when household income was included in the model. Results were similar in the model including maternal education. No signs of interactions were detected on a multiplicative scale. Weak signs of additive interaction were present, but these values did not reach significance. CONCLUSION: Both rapid and very rapid weight gain were associated with substantially higher risks of COO but these associations were not modified by SEP. This indicates that promotion of healthy weight gain should take place in all population groups irrespective of their SEP.

Determinants of non-participation in colon examination following positive stool sample in colorectal cancer screening.

BACKGROUND: Social inequalities has been shown for participation in colorectal cancer screening and recently in the initial stool sample blood test. If these differences persist at follow-up colon examination after a positive stool test, it would suggest that social inequality in screening may be greater than the inequality observed in initial stool sample blood test. METHODS: All data were derived from national registers. Using logistic regression analyses, odds of non-participation for follow-up colon examination were estimated based on age group, educational level, income quartile, immigration status and marital status in men and in women, who had participated in initial stool sample test for blood with a positive result. RESULTS: Among 20 849 men and 16 565 women invited for follow-up colonoscopy in the period 2014-15, 10.63 and 11.37%, respectively, did not attend. In men, odds of non-participation were higher in the eldest, those with lower income and lower educational level, in immigrants and in singles. Odds ratio (OR) in males of highest income quartile was 0.54 [95% confidence interval (CI) 0.46; 0.63] compared with lowest income quartile. In women, the differences were not as large. OR in females of highest income quartile was 0.73 (95% CI 0.61; 0.87) compared with lowest income quartile. CONCLUSION: Sociodemographic differences in odds of non-participation exist in follow-up colon examination in the Danish colorectal cancer screening. Differences were evident in all subgroups of the male population. The same patterns were seen in women. Social inequalities in participation for follow-up colon examination can increase overall social inequality and consequently, lead to health disparities.

The effect of early-life and adult socioeconomic position on development of lifestyle-related diseases.

BACKGROUND: Early-life socioeconomic position (SEP) is associated with lifestyle-related diseases in adulthood. However, evidence is lacking on the extent to which adult SEP mediates this association. METHODS: Time to either chronic obstructive pulmonary disease (COPD), cardiovascular disease or diabetes were assessed in the Danish population born between 1961 and 1971 (n = 793 674) from age 30 until 2015. Early-life position was assessed in 1981 (by parental) and again at age 30 (own) by four markers; income, occupation, education-divided into high, middle, low-and a combined score for all markers. Using a counterfactual approach, we estimated the total effect of early-life position on disease onset and the degree to which adult position mediated this effect. RESULTS: Results of the time-to-event analysis showed a gradient of all early-life markers on the risk of developing all lifestyle-related diseases. Notably, comparing those in the lowest to the highest educational position, the hazard of COPD was 130% higher for women [hazard ratio = 2.30(95% confidence interval = 2.20-2.41)] and 114% higher for men [2.14 (2.05-2.25)]. About 67%(63-70%) of the effect of educational position was mediated through adult position for COPD, 55% for cardiovascular disease and 50% for diabetes. For the combined score 44, 29 and 33%, respectively, was mediated. CONCLUSION: About one-tenth to two-thirds of the effect of early-life position is mediated by the position attained in adulthood. The degree mediated depend on the outcome investigated, gender and the social position marker used indicating that alternative pathways may play a key role in developing effective policies targeting early-life behaviours.
