Family wellbeing in general practice: a study protocol for a cluster-randomised trial of the web-based resilience programme on early child development.

BACKGROUND: Social, emotional and behavioural problems in early childhood are associated with increased risk for a wide range of poor outcomes associated with substantial cost and impact on society as a whole. Some of these problems are rooted in the early mother-infant relationship and might be prevented. In Denmark, primary health care has a central role in preventive care during pregnancy and the first years of the child's life and general practice provides opportunities to promote a healthy mother-infant relationship in early parenthood. OBJECTIVE: In the context of standardised antenatal and child development assessments focused on psychosocial wellbeing, we examine the impact of a complex intervention designed to improve maternal mentalisation skills, involving training of general practice clinicians and signposting towards a web-based resource. Joint main outcomes are child socio-emotional and language development at age 30 months measured by parentally reported questionnaires (Communicative Development Inventory and Strengths and Difficulties Questionnaire). METHODS: The study is a cluster-randomised controlled trial based in general practices in the Capital Region and the Zealand Region of Denmark. Seventy practices were included. Practices were randomised by a computer algorithm in a ratio of 1:1 to intervention or control groups. Each practice was asked to recruit up to 30 women consecutively at their first scheduled antenatal assessment. Clinicians in both groups received one day of training in preventive antenatal and child development consultations with added focus on parental psychosocial well-being, social support, and parent-child interaction. These preventive consultations delivered in both trial arms require enhanced data recording about psychosocial factors. In intervention clinics, clinicians were asked to signpost a web page at three scheduled antenatal consultations and at four scheduled consultations when the child is 5 weeks, 5 months, 1 and 2 years. DISCUSSION: We hypothesise that the intervention will increase mothers' ability to be sensitive to their child's mental state to an extent that improves the child's language and mental state at 30 months of age measured by parent-reported questionnaires.

The predictive value of common symptoms in early pregnancy for complications later in pregnancy and at birth.

INTRODUCTION: The aim was to investigate whether common pregnancy-related symptoms-nausea, vomiting, back pain, pelvic girdle pain, pelvic cavity pain, vaginal bleeding, itching of vulva, pregnancy itching, leg cramps, uterine contractions and varicose veins-in the first trimester of pregnancy add to the identification of women at high risk of future pregnancy and birth complications. MATERIAL AND METHODS: Survey data linked to national register data. All women booking an appointment for a first prenatal visit in one of 192 randomly selected General Practices in East Denmark in the period April 2015-August 2016. The General Practices included 1491 women to this prospective study. Two outcomes, pregnancy complications and birth complications, were collected from the Danish Medical Birth Register. RESULTS: Among the 1413 included women, 199 (14%) experienced complications in later pregnancy. The most serious complication, miscarriage, was experienced by 65 women (4.6%). Other common pregnancy complications were gestational diabetes mellitus (n = 11, 0.8%), gestational hypertension without proteinuria (n = 34, 2.4%), mild to moderate preeclampsia (n = 34, 2.4%) and gestational itching with effect on liver (n = 17, 1.2%). Women who experienced pelvic girdle pain, pelvic cavity pain or vaginal bleeding in the first trimester of pregnancy had a higher risk of pregnancy complications later on in later pregnancy. None of the other examined symptoms showed associations to pregnancy complications. No associations were found between pregnancy-related physical symptoms in first trimester and birth complications. CONCLUSIONS: Symptoms in early pregnancy do not add much information about the risk of pregnancy or birth complications, although pain and bleeding may give reason for some concern. This is an important message to women experiencing these common symptoms and to their caregivers.

The association of a past childbirth experience with a variety of early physical and mental symptoms in subsequent pregnancies.

BACKGROUND: Some women have a perceived negative experience of childbirth due to various reasons- e.g., obstetric complications or the feeling of loss of control. We do not know enough about the effects of a perceived negative experience of a childbirth on a woman's subsequent pregnancies. The aim of this study was to investigate whether a previously perceived negative childbirth experience affects a woman's physical and mental well-being in a later pregnancy. METHODS: A prospective cohort study in Danish general practice, based on information about women's childbirth experiences from the Pregnancy Health Record filled in by the general practitioner (GP) and data from an electronic questionnaire completed by the women. RESULTS: A total of 1288 women were included in the analysis. Women who had given birth before were found to have a significantly higher risk of experiencing nausea, varicose veins and uterine contractions, and a lower risk of pelvic cavity pain in the current pregnancy. Women having given birth before were significantly more likely to assess their physical fitness as poor and to experience poor well-being. Women with a perceived negative experience of childbirth had more sleep problems and a higher prevalence of poor self-rated health than women with unproblematic childbirth experience. CONCLUSION: This study showed that women with a previously perceived negative experience of childbirth are affected according to their mental health in their subsequent pregnancy.

Mental well-being during stages of COVID-19 lockdown among pregnant women and new mothers.

BACKGROUND: Pregnancy and early motherhood are sensitive times where epidemic disease outbreaks can affect mental health negatively. Countries and health care systems handled the pandemic and lockdowns differently and knowledge about how the COVID-19 pandemic affected the mental well-being of pregnant women and new mothers is limited and points in different directions. AIM: To investigate symptoms of anxiety and depression in a population of pregnant women and new mothers in various stages of infection pressure and lockdown during the first 15 months of the COVID-19 pandemic in Denmark. METHODS: The study population was nested an inception cohort of women recruited in their first trimester of pregnancy. Data about mental health of the woman were obtained in relation to pregnancy and child development (first trimester, 8 weeks postpartum and 5 months postpartum), and data were analysed cross-sectionally according to calendar time (periods defined by infection rate and lock-down during the COVID-19 pandemic). RESULTS: No differences in reported levels of depressive symptoms between the six examined time periods of the pandemic were observed. Specifically, symptoms remained unchanged after the first lock-down. No major changes in anxiety symptoms were observed in relation to increased infection pressure or lockdowns, but a small increase was observed during the second lockdown in women 8 weeks postpartum. CONCLUSION: No clear change in mood among pregnant women was seen between during the stages of COVID-19 pandemic in Denmark.

Mental vulnerability before and depressive symptoms during pregnancy and postpartum: a prospective population-based cohort study from general practice.

PURPOSE: The aim was to investigate and compare the prevalence of symptoms of depression throughout pregnancy and postpartum among women who at the first pregnancy consultation had (1) record of mental disease, (2) self-reported psychological difficulties but no record of mental disease, or (3) no mental vulnerability. MATERIALS AND METHODS: Prospective cohort study. An electronic questionnaire containing the Major Depression Inventory (MDI) was e-mailed to 1494 pregnant women after the first, second and third prenatal care consultation and eight weeks postpartum. High depression score was considered present with MDI scores of 21 or more. Information on sociodemographic, somatic comorbidities and previous psychiatric disorders was collected. We used logistic regression to estimate odds ratios with 95% confidence intervals. RESULTS: The overall prevalence of symptoms of depression (MDI ≥ 21) dropped throughout pregnancy. At the first prenatal care consultation the prevalence was 15.3%, 10.7% in the second trimester, 9.3% in the third trimester and 5.6% postpartum. Logistic regression showed increased risk of symptoms of depression throughout pregnancy and postpartum for both women with mental disease and psychological difficulties. For each outcome, the increase in odds for the psychological difficulties group was about one third of the increase in odds for the mental illness group. CONCLUSIONS: Self-reported psychological difficulties may indicate higher odds of depressive symptoms. The healthcare staff meeting the pregnant women in early pregnancy have a good opportunity to identify this subgroup of vulnerable women by means of the Pregnancy Health Records and additional questions exploring women's experiences with previous psychological difficulties.

Infant crying problems related to maternal depressive and anxiety symptoms during pregnancy: a prospective cohort study.

BACKGROUND: Infant crying may cause concerns among new parents and is a frequent reason for seeking help from their general practitioner (GP). The etiology of crying problems in infancy is not fully understood, but recent studies have found associations with maternal mental factors. It is well-established that postpartum depression is related to infant crying problems while the influence of maternal mental problems in pregnancy on infant crying is less investigated. We aimed to explore whether maternal depressive symptoms or maternal anxiety during pregnancy were related to crying problems by the newborn child. METHODS: In this prospective cohort study, 1290 pregnant women and their newborn children were followed throughout pregnancy until 8 weeks postpartum. Depressive symptoms and anxiety symptoms were assessed three times during pregnancy and again 8 weeks postpartum with the Major Depressive Inventory (MDI) and the Anxiety Symptoms Scale (ASS). Eight weeks postpartum the mothers were also asked whether their child cried in a way they found problematic. Multivariable regression was used to assess the association between depressive and anxiety symptoms during pregnancy and crying problems, and to adjust for potential confounders. RESULTS: We found statistically significant associations between high scores of depressive symptoms and anxiety symptoms in pregnancy and infant crying problems. Previously reported strong associations postpartum between depressive symptoms, anxiety symptoms and infant crying problems were also observed in the present data. CONCLUSION: These results indicate that mental problems during pregnancy are associated with having a child with crying problems after birth. If more focus is given to maternal mental problems during pregnancy, the healthcare system might be able to detect and help these women, which would be beneficial for both mother and child.

Depression and anxiety symptoms in pregnant women in Denmark during COVID-19.

AIMS: Maternal mental distress in pregnancy can be damaging to the mother's and child's physical and mental health. This study aimed to provide an insight into mental well-being of pregnant women in Denmark during COVID-19 by assessing symptoms of depression and anxiety. METHODS: Data from two cohorts of pregnant women recruited from Danish general practice were compared. A COVID-19 lockdown cohort (N=330) completed questionnaires between 8 April and 6 May. Responses were compared to those from a control cohort of women from 2016 (N=1428). Mental well-being was measured with the Major Depression Inventory (MDI) and the Anxiety Symptom Scale (ASS). RESULTS: Questionnaires were returned by 83% of the COVID-19 lockdown cohort and by 93% of the control cohort. Multivariable analysis controlling for age, cohabitation status, occupation, smoking, alcohol use, chronic disease, fertility treatment, parity and children living at home showed no difference in depressive symptoms (MDI). Anxiety symptoms (ASS) were slightly worse in the COVID-19 lockdown cohort (mean difference=1.4 points), mainly driven by questions concerning general anxiety. The largest differences in anxiety were seen in first trimester (adjusted mean difference=4.0 points). CONCLUSIONS: Pregnant women questioned during the COVID-19 pandemic showed no change in symptoms of depression and only a modest elevation of anxiety when compared to pregnant women questioned during a non-pandemic period in 2016.

What factors are most important for the development of the maternal-fetal relationship? A prospective study among pregnant women in Danish general practice.

BACKGROUND: Development of the maternal antenatal attachment (MAA) constitutes an important aspect of the transition into motherhood. Early identification of women at risk of developing a poor MAA provides possibilities for preventive interventions targeting maternal mental health and the emerging mother-infant relationship. In this study, we investigate the relative importance of an extensive set of psychosocial, pregnancy-related, and physiological factors measured in the first trimester of pregnancy for MAA measured in third trimester. METHODS: A prospective study was conducted among pregnant women in Danish general practice (GP). Data were obtained in the first and the third trimester from pregnancy health records and electronic questionnaires associated with routine GP antenatal care visits. The Maternal Antenatal Attachment Scale (MAAS) was used to assess maternal antenatal attachment. The relative importance of potential determinants of maternal antenatal attachment was assessed by the relative contribution of each factor to the fit (R2) calculated from multivariable regression models. RESULTS: The sample consisted of 1328 women. Low antenatal attachment (Total MAAS ≤ 75) was observed for 513 (38.6%) women. Perceived social support (having someone to talk to and having access to practical help when needed) emerged as the most important determinant. Furthermore, scores on the MAAS decreased with worse self-rated health, poor physical fitness, depression, increasing age, having given birth previously, and higher education. CONCLUSION: Pregnant women reporting lack of social support and general low physical and mental well-being early in pregnancy may be at risk for developing a poor MAA. An approach targeting both psychosocial and physiological well-being may positively influence expectant mothers' successful adaptation to motherhood.

Pregnant women's concerns and antenatal care during COVID-19 lock-down of the Danish society.

INTRODUCTION: Pandemics are known to cause stress and anxiety in pregnant women. During the coronavirus disease 2019 (COVID-19) lockdown of the Danish society, pregnant women were considered to be at increased risk, and access to antenatal care changed. METHODS: On 8 April 2020A, a questionnaire was sent to 332 pregnant women previously sampled by general practitioners in two Danish regions. The women were contacted via secured e-mail (e-Boks), and questionnaires were returned until 6 May. RESULTS: The questionnaire was returned by 257 women (77%). More than half believed that they were at a high risk of infection with COVID-19, and a third of the women were concerned about the risk of serious disease - especially for their unborn child. Almost 90% isolated at home most of the time. The majority were worried about possible consequences of the pandemic for antenatal care, but very few had actually missed a scheduled preventive consultation with their general practitioner, and only 15% had missed an appointment with their midwife. The majority of the women preferred normal consultations and found no added safety in shifting the consultation from the normal clinical setting. CONCLUSIONS: The COVID-19 pandemic and lockdown have had a major impact on Danish pregnant women. Even so, concerns were more focused on access to care than on the risk of COVID-19 infection. Contacts with the antenatal healthcare system have only been moderately affected. FUNDING: TRYG Foundation and KEU, Region Copenhagen. TRIAL REGISTRATION: not relevant.

Selection bias in general practice research: analysis in a cohort of pregnant Danish women.

OBJECTIVE: The aim of the present study was to examine selection in a general practice-based pregnancy cohort. DESIGN: Survey linked to administrative register data. SETTING AND SUBJECTS: In spring 2015, GPs were recruited from two Danish regions. They were asked to invite all pregnant women in their practice who had their first prenatal care visit before 15 August 2016 to participate in the survey. OUTCOME MEASURES: The characteristics of GPs and the pregnant women were compared at each step in the recruitment process - the GP's invitation, their agreement to participate, actual GP participation, and the women's participation - with an uncertainty coefficient to quantify the step where the largest selection occurs. RESULTS: Significant differences were found between participating and non-participating practices with regards to practice characteristics such as the number of patients registered with the practice, the age and sex of doctors, and the type of practice. Despite these differences, the characteristics of the eligible patients differed little between participating and non-participating practices. In participating practices significant differences were, however, observed between recruited and non-recruited patients. CONCLUSION: The skewed selection of patients was mainly caused by a high number of non-participants within practices that actively took part in the study. We recommend that a focus on the sampling within participating practices be the most important factor in representative sampling of patient populations in general practice. Key points Selection among general practitioners (GPs) is often unavoidable in practice-based studies, and we found significant differences between participating and non-participating practices. These include practice characteristics such as the number of GPs, the number of patients registered with the GP practice, as well as the sex and age of the GPs. •Despite this, only small differences in the characteristics of the eligible patients were observed between participating and non-participating practices. •In participating practices, however, significant differences were observed between recruited and non-recruited patients. •Comprehensive sampling within participating practices may be the best way to generate representative samples of patients.

Sleep complaints in early pregnancy. A cross-sectional study among women attending prenatal care in general practice.

BACKGROUND: Sleep problems in late pregnancy are common, but sleep in early pregnancy is less well described. The aim of this study was to describe the occurrence and severity of sleep complaints in early pregnancy. We asked the women about worries due to sleep problems. Furthermore, we investigated the associations between sleep complaints and pregnancy-related symptoms. This association was studied taking into account physical and mental health, sociodemographic characteristics, and reproductive history of the women. METHODS: Cross-sectional study in Danish general practice based on an electronic questionnaire completed by pregnant women and a Pregnancy Health Record filled in by the general practitioner (GP). The questionnaire measured three sleep complaints and 11 common physical pregnancy-related symptoms. The sleep complaints were measured as mild, moderate or severe, and it was recorded how much they worried the women. The associations between the physical pregnancy-related symptoms and sleep complaints were assessed by odds ratios from multivariable logistic regression models. RESULTS: The questionnaire was completed by 1338 out of 1508 eligible women before the end of gestation week 16. The gestational age ranged from 5 to 16 weeks (median 11 weeks) among the included women. On average, more than one third of the women reported to have at least one of the three sleep complaints in the questionnaire. Problems "taking a long time to fall asleep" was reported by 312 women (23%), "waking up too early" was reported by 629 (47%), and 183 (14%) had been "lying awake most of the night". One sleep complaint was reported by 38%, two by 16, and 4% had all three symptoms. The majority were not at all or only mildly worried because of their sleep disturbances, but moderate or severe worries were found among 46% of those" taking a long time to fall asleep" and among 40% of those "lying awake most of the night". "Moderate or severe complaints" were reported by 277 (21%) women "Moderate or severe complaints" were associated with pregnancy-related physical symptoms, such as back pain, pelvic girdle pain and pelvic cavity pain, but only the association with pelvic cavity pain stayed significant after adjustment for depression. CONCLUSION: This study showed that sleep complaints in early pregnancy are common, and sleep complaints showed association with physical as well as mental symptoms. It may be important for pregnant patients that clinicians address depression, and mood in relation to sleep problems during pregnancy.

Examining to what extent pregnancy-related physical symptoms worry women in the first trimester of pregnancy: a cross-sectional study in general practice.

BACKGROUND: Women often wish to discuss their pregnancy symptoms with their GP. However, the two parties' understanding of symptoms may not be aligned. AIM: To examine to what degree a specific pregnancy-related symptom worried women in the first trimester and analyse the characteristics of the most worried women. DESIGN & SETTING: A cross-sectional study was performed in general practice in Denmark from 1 March 2015-15 August 2016. METHOD: Women attending the first prenatal care visit completed a questionnaire about pregnancy-related physical symptoms and worries. Women were recruited from 125 GP practices and 294 GPs participated in the study. Further data were obtained from their pregnancy health record. Multivariable logistic regression analysis was used to assess the associations between the women's worries and the severity of the symptoms, which were adjusted for age and parity. RESULTS: A total of 1508 women, aged 16-45 years, were included and 1455 completed the questionnaire. Nausea, vomiting, pelvic cavity pain, and back pain were the most common symptoms, and 88% reported having two or more symptoms simultaneously. Among the 1278 women reporting nausea, only 21% were worried, while 88% of the 252 women reporting vaginal bleeding were worried. Primigravidae (those pregnant for the first time) were significantly more worried about vomiting and nausea than multigravidae (those who have experienced pregnancy previously). Those aged >35 years were more worried about pelvic girdle pain and pelvic cavity pain than younger women. CONCLUSION: Pregnancy-related physical symptoms are frequent in the first trimester. The severity of worries depends on the symptom. Vaginal bleeding and pain give rise to the majority of severe worries, especially among young women.

Labour market attachment after mild traumatic brain injury: nationwide cohort study with 5-year register follow-up in Denmark.

OBJECTIVES: Sickness absence after mild traumatic brain injury (mTBI) is frequent due to postconcussive symptoms. We examined labour market attachment following mTBI up to 5 years postinjury. DESIGN AND SETTING: Nationwide cohort study with register follow-up. PARTICIPANTS: Patients between 18 and 60 years with mTBI (International Classification of Diseases, version 10 diagnosis S06.0) were extracted from the Danish National Patient Register (n=19 732). Controls were matched on sex, age and municipality (n=18 640). Patients with spinal cord and column injuries, traumatic brain injury and concussions 5 years preinjury or as secondary diagnosis to the concussion in the inclusion period were excluded. PRIMARY AND SECONDARY OUTCOME MEASURES: Data were extracted from the Danish Register for Evaluation of Marginalization. Primary outcome was 'not attending ordinary work' defined as receiving any social transfer payment. Secondary outcomes were health-related benefits, limited attachment to the labour market, permanent lack of attachment to the labour market and death. RESULTS: 5 years after diagnosis, 43% of patients were not attending ordinary work. The odds increased from 6 months (OR 1.30, 95% CI 1.24 to 1.36) to 5 years (OR 1.54, 95% CI 1.45 to 1.63). The odds of health-related benefits were 32% (OR 1.32, 95% CI 1.22 to 1.42) at 6 months and 22% (OR 1.22, 95% CI 1.12 to 1.33) at 5 years. Limited attachment to the labour market showed increased odds at 5 years (OR 1.38, 95% CI 1.27 to 1.51) and the odds of permanent lack of attachment to the labour market were higher for patients compared with controls (OR 2.59, 95% CI 2.30 to 2.92). Death was more than two times higher at 5 years postinjury (OR 2.62, 95% CI 2.10 to 3.26). CONCLUSIONS: 43% of concussed patients were not attending ordinary work 5 years postinjury and received health and social transfer benefits. We conclude that mTBI has a long-term impact on labour market attachment. Prevention and treatment of persisting postconcussive symptoms should be considered. TRIAL REGISTRATION NUMBER: NCT03214432; Results.

Premorbid risk factors influencing labour market attachment after mild traumatic brain injury: a national register study with long-term follow-up.

OBJECTIVES: Some patients with mild traumatic brain injury (mTBI) experience persistent postconcussive symptoms, influencing the ability to work. This study assessed associations between mTBI and labour market attachment (up to 5 years postinjury) in patients with different premorbid characteristics. DESIGN AND SETTING: Danish national cohort study with 5-year register follow-up. PARTICIPANTS: We included hospital admitted patients between 18 and 60 years diagnosed with mTBI (International Classification of Diseases, version 10 diagnosis S06.0) (n=19 732). For each patient, one control was selected matched on age, gender and municipality (n=18 640). PRIMARY OUTCOME MEASURE: Primary outcome was 'not attending ordinary work', and premorbid risk factors were cohabitation status, education, ethnicity, gender, age and comorbidities. RESULTS: The odds of not attending ordinary work increased from 6 months to 5 years. The highest increased odds (approximately twice as high for patients) of not attending ordinary work at 5 years were found in the highest educational group (OR 2.15, 95% CI 1.78 to 2.59), for patients of non-Danish origin (OR 1.98, 95% CI 1.52 to 2.57), for patients between 30 and 39 years (OR 1.93, 95% CI 1.68 to 1.23) and for patients with somatic comorbidities (OR 1.81, 95% CI 1.38 to 2.37). Contrary to expectations, we did not find higher odds in patients with psychiatric diagnoses (OR 1.12, 95% CI 0.76 to 1.60). CONCLUSIONS: Important premorbid characteristics for lower labour market participation after mTBI were higher education, non-Danish origin, age 30-39 years and having somatic comorbidities. Demographic and health-related variables should be considered when assessing patients with mTBI at risk of long-term sickness absence. TRIAL REGISTRATION NUMBER: NCT03214432; Results.

Physical discomfort in early pregnancy and postpartum depressive symptoms.

PURPOSE: Pregnancy examinations conducted in general practice focus mainly on identifying high-risk pregnancies and pregnancy complications. The pregnancy health record has a biomedical focus, and consequently the woman's mental well-being may receive less attention. The aim of this study was to evaluate the extent to which early pregnancy-related symptoms should be considered as indicators of an increased risk of postpartum depression. MATERIALS AND METHODS: For a prospective cohort of 1508 pregnant women, the presence of 11 pregnancy-related symptoms was recorded at the first prenatal care consultation together with background information about socio-demography and health. Depression was assessed 8 weeks postpartum with the major depression inventory (MDI) and depression was considered present if MDI > 20. Multivariable logistic regression was used to assess the association between pregnancy-related symptoms and postpartum depressive symptoms, and to adjust for potential confounders. RESULTS: A high depression score (MDI score >20) 8 weeks postpartum was found among 6.6% of the women and showed apparent associations with physical discomfort in early pregnancy, such as back pain and pelvic cavity pain. Analysis of confounding revealed, however, that signs of vulnerable mental health, present in early pregnancy, explained most of these associations. CONCLUSIONS: Indicators of an increased risk of postpartum depressive symptoms may be found in early pregnancy. Pregnancy-related pain in the first trimester may be a sign of psychological vulnerability or an aspect of an existing depressive state that calls for attention.

The Effect of Economic Assets on Mortality in Patients with Dementia: A Population-Based Cohort Study.

BACKGROUND: We investigated the effect of economic assets on mortality in patients with dementia in a national cohort of elderly individuals aged 65 or older. OBJECTIVE: To examine the effect of economic assets on mortality in patients with dementia. METHODS: Incidence of dementia and all-cause mortality was analyzed with incidence rate ratios (IRR) in three different categories of economic assets by means of Cox regression models. RESULTS: A total of 874,246 individuals aged 65+ were included. The risk of receiving a dementia diagnosis was highest in the low economic asset group (IRR 1.19). Patients with dementia had a higher mortality compared to those without a diagnosis (IRR 2.85). The mortality in the dementia group was lowest in the high economic asset group (IRR 3.31). However, the increase associated with dementia was lowest within the low economic assets group (IRR 2.57). CONCLUSION: Mortality is increased with a dementia diagnosis and highest for the low economic asset group. However, the increase in mortality attributable to dementia was higher in the high economic assets group.

Predictors of undiagnosed prevalent type 2 diabetes - The Danish General Suburban Population Study.

AIMS: To investigate how self-reported risk factors (including socioeconomic status) predict undiagnosed, prevalent type 2 diabetes mellitus (T2DM). To externally validate Leicester Risk Assessment Score (LRAS), Finnish Diabetes Risk Score (FINDRISC) and Danish Diabetes Risk Score (DDRS), and to investigate how these predict a European Heart SCORE≥5% in a Danish population study. METHODS: We included 21,205 adults from the Danish General Suburban Population Study. We used relative importance calculations of self-reported variables in prediction of undiagnosed T2DM. We externally validated established prediction models reporting ROC-curves for undiagnosed T2DM, pre-diabetes and SCORE. RESULTS: More than 20% of people with T2DM were undiagnosed. The 7 most important self-rated predictors in sequential order were high BMI, antihypertensive-therapy, age, cardiovascular disease, waist-circumference, fitness compared to peers and family disposition for T2DM. The Area Under the Curve for prediction of undiagnosed T2DM was 77.1 for LRAS; 75.4 for DDRS and 67.9 for FINDRISC. AUCs for SCORE was 75.1 for LRAS; 62.3 for DDRS and 54.3 for FINDRISC. CONCLUSIONS: BMI and self-reported cardiovascular disease are important risk factors for undiagnosed T2DM. LRAS performed better than DDRS and FINDRISC in prediction of undiagnosed T2DM and SCORE≥5%. SCORE performed best in predicting pre-diabetes.

Socio-demographic determinants and effect of structured personal diabetes care: a 19-year follow-up of the randomized controlled study diabetes Care in General Practice (DCGP).

BACKGROUND: We investigated how four aspects of socio-demography influence the effectiveness of an intervention with structured personal diabetes care on long-term outcomes. METHODS: The Diabetes Care in General Practice (DCGP) study is a cluster-randomized trial involving a population-based sample of 1381 patients with newly diagnosed type 2-diabetes mellitus. We investigated how education, employment, cohabitation status and residence influenced the effectiveness of 6 years of intervention with structured personal diabetes care, resembling present day recommendations. Outcomes were incidence of any diabetes-related endpoint and death during 19 years after diagnosis, and cardiovascular risk factors, behaviour, attitudes and process-of-care variables 6 years after diagnosis. RESULTS: Structured personal care reduced the risk of any diabetes-related endpoint and the effect of the intervention was modified by geographical area (interaction p = 0.034) with HR of 0.71 (95%CI: 0.60-0.85) and of 1.07 (95%CI: 0.77-1.48), for patients in urban and rural areas, respectively. Otherwise, there was no effect modification of education, employment and civil status on the intervention for the final endpoints. There were no noticeable socio-demographic differences in the effect of the intervention on cardiovascular risk factors, behaviour, attitudes, and process-of-care. CONCLUSION: Structured personal care reduced the aggregate outcome of any diabetes-related endpoint and independent of socio-demographic factors similar effect on cardiovascular risk factors, behaviour, attitudes and process of care, but the intervention did not change the existing inequity in mortality and morbidity. Residence modified the uptake of the intervention with patients living in urban areas having more to gain of the intervention than rural patients, further investigations is warranted. TRIAL REGISTRATION: ClinicalTrials.gov registration no. NCT01074762 (February 24, 2010).

Exploring the concurrent validity of the nationwide assessment of permanent nursing home residence in Denmark - A cross-sectional data analysis using two administrative registries.

BACKGROUND: Many register studies make use of information about permanent nursing home residents. Statistics Denmark (StatD) identifies nursing home residents by two different indirect methods, one based on reports from the municipalities regarding home care in taken place in a nursing home, and the other based on an algorithm created by StatD. The aim of the present study was to validate StatD's nursing home register using dedicated administrative municipality records on individual nursing home residents as gold standard. METHODS: In total, ten Danish municipalities were selected. Within each Danish Region, we randomly selected one municipality reporting to Stat D (Method 1) and one not reporting where instead an algorithm created by StatD was used to discover nursing home residents (Method 2). Method 1 means that municipalities reported to Stat D whether home care has taken place in a nursing home or in a private home. Method 2 is based on an algorithm created by Stat D for the municipalities where Method 1 is not applicable. Our gold standard was the information from the local administrative system in all ten selected municipalities. Each municipality provided a list with all individuals > 65 years living in a nursing home on January 1st, 2013 as well as the central personal number. This was compared to the list of individuals >65 living in nursing home facilities in the same ten municipalities on January 1st, 2013 retrieved from StatD. RESULTS: According to the data received directly from the municipalities, which was used as our gold Standard 3821 individuals were identified as nursing home residents. The StatD register identified 6,141 individuals as residents. Additionally, 556 of the individuals identified by the municipalities were not identified in the StatD register. Overall sensitivity for the ten municipalities in the StatD nursing home register was 0.85 (95% CI 0.84-0.87) and the PPV was 0.53 (95% CI 0.52-0.54). The municipalities for which nursing home status was based on the StatD algorithm (method 2) had a sensitivity of 0.84 (95% CI 0.82-0.86) and PPV of 0.48 (95% CI 0.46-0.50). Both slightly lower than the reporting municipalities (method 1) where the sensitivity was 0.87(95% CI 0.85-0.88) and the PPV was 0.57 (95% CI 0.56-0.59). Additionally, the sensitivity and PPV of the Stat D register varied heavily among the ten municipalities from 0.51 (95% CI 0.43-0.59) to 0.96 (95% CI 0.95-0.98) and PPV correspondingly, from 0.14 (95% CI: 0.11-0.17) to 0.73 (95% CI 0.69-0.77). CONCLUSIONS: The overall PPV of StatD nursing home register was low and differences between municipalities existed. Even in countries with extensive nation-wide registers, validating studies should be conducted for outcomes based on these registers.

Social disparities in diabetes care: a general population study in Denmark.

OBJECTIVE: We investigated the association between socioeconomic factors and the attainment of treatment goals and pharmacotherapy in patients with type 2 diabetes in Denmark. DESIGN: A cross-sectional population study. SETTING: The municipality of Naestved, Denmark. SUBJECTS: We studied 907 patients with type 2 diabetes identified from a random sample of 21,205 Danish citizens. MAIN OUTCOME MEASURES: The proportion of patients who were not achieving goals for diabetes care based on their HbA1c, LDL-cholesterol, blood pressure, and lifestyle, and the proportion of patients who were treated with antihypertensive and cholesterol- and glucose-lowering medication. METHODS: We investigated the association of the socioeconomic factors such as age, gender, education, occupation, income, and civil status and attainment of treatment goals and pharmacotherapy in logistic regression analyses. We investigated effect modification of cardiovascular disease and kidney disease. RESULTS: Middle age (40-65 years), low education level (i.e. basic schooling), and low household income (i.e. less than 21,400 € per year) were associated with nonattainment of goals for diabetes care. The association of socioeconomic factors with attainment of individual treatment goals varied. Patients with low socioeconomic status were more often obese, physically inactive, smoking, and had elevated blood pressure. Socioeconomic factors were not associated with treatment goals for hyperglycemia. Socioeconomic factors were inconsistently associated with pharmacotherapy. There was no difference in contacts to general practitioners according to SES. CONCLUSIONS: In a country with free access to health care, the socioeconomic factors such as middle age, low education, and low income were associated with nonattainment of goals for diabetes care. KEY POINTS Middle age, low education, and low income were associated with nonattainment of goals for diabetes care, especially for lifestyle goals. Patients with low socioeconomic status were more often obese, physically inactive, smoking, and had elevated blood pressure. Association of socioeconomic factors with pharmacotherapy was inconsistent.
