Objectives: To evaluate compliance with the national recommendation on supplemental iron to all pregnant women in Denmark and to explore differences between compliers and non-compliers with respect to dietary habits and other lifestyle factors.Design: Intake of supplemental iron from pure iron supplements and from multivitamin and mineral preparations was estimated in mid-pregnancy.Setting: Nationwide cohort study, the Danish National Birth Cohort (DNBC), comprising more than 100,000 women recruited in early pregnancy.Subjects: Information on diet and dietary supplements was available for 54,371 women. Of these, information on lifestyle factors was available for 50,902 women.Results: A high compliance with the recommendation was found, as approximately 77% of the women reported use of iron supplements during pregnancy. However, many of the compliers did not obtain the recommended doses of iron, which can partly be explained by the lack of iron preparations of appropriate doses available on the Danish market. Compliance with the recommendation was associated with age above 20 years, primiparity, body mass index<30 kg m- 2, non-smoking and long education. No major differences were seen in dietary intake between compliers and non-compliers.ConclusionOverall, a high compliance rate was found among participants of the DNBC but a clarification on daily dose is needed, and more concern should be paid to vulnerable groups such as young, smoking women and women with no or short education.

Objective: To validate intakes of protein, folic acid, retinol and n-3 fatty acids estimated from a food-frequency questionnaire in week 25 of pregnancy (FFQ-25).Design: Validation was done against a 7-day weighed food diary (FD) and biomarkers of the nutrients in gestation week 32-38.Subjects and Setting: The FFQ-25 to be validated was used in the Danish National Birth Cohort comprising 101 042 pregnant Danish women, of whom 88 participated in the present validation study.Results: Estimated intakes of protein, retinol and folic acid did not differ significantly between the two dietary methods, but intake of n-3 fatty acids was one third larger when estimated from the FFQ-25. The intakes estimated from the two dietary methods were all significantly correlated, ranging from 0.20 for retinol intake to 0.57 for folic acid intake. Sensitivities of being correctly classified into low and high quintiles were between 0.22 and 0.77, and specificities were between 0.62 and 0.89. Urinary protein content did not correlate significantly with protein estimated from the FFQ (r = 0.17, P > 0.05), but did with intake estimated from the FD (r = 0.56, P < 0.0001). Erythrocyte folate correlated significantly with the estimated total intake from the FFQ (r = 0.55, P < 0.0001) and the FD (r = 0.52, P < 0.0001). No correlations with plasma retinol were found. Erythrocyte eicosapentaenoic acid (C20:5n-3) correlated significantly with n-3 fatty acids intake estimated from both the FFQ-25 (r = 0.37, P < 0.001) and the FD (r = 0.62, P < 0.0001).Conclusion: The FFQ-25 gives reasonable valid estimates of protein, retinol and folic acid intakes, but seems to overestimate intake of n-3 fatty acids.

Objective: As a means to prevent neural tube defects (NTDs), women planning pregnancy in Denmark are recommended to take a dietary supplement of 400 microg folic acid daily during the periconceptional period. We examined compliance with this recommendation in a national survey.Design: Cohort study on pregnant women in Denmark.Setting: The Danish National Birth Cohort (DNBC).Subjects: From November 2000 to February 2002, 22,000 pregnant women were recruited for DNBC. Use of dietary supplements was recorded at enrollment. Compliance with the recommendation was related to an information campaign that took place during the second half of 2001, and to lifestyle factors provided in a telephone interview by the end of the first trimester of pregnancy.Results: An increase was seen in the proportion of women complying with the recommendation in the study period and this coincided with the information campaign events. However, even at the end of the period, only 22.3% of the women who had planned their pregnancy fully complied with the recommendation. No increase at all was seen in periconceptional folic acid use among women with unplanned pregnancies. Young age, low education and smoking were identified as factors that determined non-compliance.Conclusions: Alternative and more effective strategies are needed if the Danish population is to benefit fully from the knowledge that folic acid prevents NTDs. Future strategies should not only target vulnerable groups, such as the less educated and the young, but also women who get pregnant without planning this. The only possible way to reach the last group may be through fortification of foods with folic acid. [ABSTRACT FROM AUTHOR]

Aims: (a) To investigate support for caregivers of people diagnosed with stroke, cancer, chronic obstructive pulmonary disease (COPD), dementia, or heart disease provided across healthcare settings in Denmark; (b) to assess differences in caregiver support across diagnoses and settings., Methods: A cross-sectional nationwide survey among professionals representing healthcare settings at municipalities ( n = 479) and hospital wards and outpatient clinics ( n = 425). The survey assessed identification of caregivers and support initiatives., Results: The response rate was 81% for municipalities and 49% for hospitals. Identification of caregivers was frequent in dementia care (81% and 100%) and less frequent in COPD care (58% and 64%) in municipalities and hospitals, respectively. Caregiver support differed significantly across diagnoses within municipalities ( p = 0.009) and hospitals ( p < 0.001). Systematic identification of vulnerable caregivers was <25% for all diagnoses except dementia. The most common support initiatives involving caregivers were primarily aimed at the ill person and included guidance about the disease and consequences for everyday life and lifestyle changes. Caregivers were least involved in support initiatives addressing physical training, work retention, sexuality, or cohabitation., Conclusions: Disparities and significant differences across diagnoses exist in the identification of caregivers and the provision of support initiatives. Support initiatives involving caregivers primarily targeted patients. Future studies should investigate how caregivers' needs can be met across different diagnoses and healthcare settings and investigate potential changes in caregivers' needs during disease trajectories. In clinical practice, identification of vulnerable caregivers should be a major focus, and disease-specific clinical guidelines may be required to ensure sufficient support for caregivers., Competing Interests: Declaration of conflicting interestsThe authors have no conflicts of interest to declare.

Aim: Long-term cognitive decline after out-of-hospital cardiac arrest (OHCA) is still poorly understood. This study describes long-term observer-reported cognitive decline among Danish OHCA survivors, including differences in years since the event, and investigates characteristics and self-reported outcomes associated with observer-reported cognitive decline., Methods: Adults who survived an OHCA from 2016 to 2019, and their relatives, completed the national DANish Cardiac Arrest Survivorship survey. Relatives completed the Informant Questionnaire on Cognitive Decline in the Elderly, Cardiac Arrest version (IQCODE-CA), the Hospital Anxiety and Depression Scale (HADS) and the World Health Organisation-Five Well-being index; and survivors completed the Two Simple Questions (everyday activities and mental recovery), the Modified Fatigue Impact Scale, HADS, and the Short World Health Organisation Disability Assessment Schedule 2.0. Potential associations between survivor characteristics and the IQCODE-CA were investigated using a multivariable logistic regression model. Self-reported outcomes among survivors and relatives, and the association with IQCODE-CA scores were investigated using separate logistic regression models., Results: Total median IQCODE-CA score was 3.04 (IQR: 3.00-3.27), with 47% having possible cognitive decline (score ≥ 3.04), consistent across time groups. Increasing age (OR 0.98, 95% CI: 0.97-0.99) and worse self-reported mental and physical outcomes for survivors and relatives, except 'everyday activities' were significantly associated with possible cognitive decline among survivors., Conclusions: Nearly half of OHCA survivors may suffer long-term cognitive decline. Worse self-reported mental and physical outcomes among survivors and their relatives are associated with potential cognitive decline emphasising the need for post-OHCA care to include systematic neurocognitive assessment, tailored support and effective rehabilitation., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Aims: Based on selected themes from a national survey, the study aims to describe and analyse similarities and differences in community-based palliative care provided to people living at home in two different care settings - the nursing home setting and the home care setting., Methods: Responses from four palliative care themes covered by a national survey sent to 717 managers in municipality-based care units were used. The themes were: (a) target groups in palliative care; (b) wishes for end-of-life care; (c) tools/guidelines in palliative care; and (d) palliative care provided to relatives., Results: The response rates were 53% in the nursing home setting and 69% in the home care setting (69%). Both settings had target groups for palliative care, in which significantly more units in the home care settings cared for people with other cultural backgrounds or children. Wishes for end-of-life care were addressed by more than 90% of the units in both settings. There were significantly more nursing home units that addressed questions regarding resuscitation, decision making when you are incapable of making decisions for yourself, and the level of medication. In both settings, around half of the units did not use or did not know if they used tools/guidelines to identify palliative care needs. Half of home care and 65% of nursing home settings did not/were unaware of providing palliative care to relatives., Conclusions: Both settings serve target populations for palliative care with few differences. Identifying palliative care needs seemed to be a low priority in both settings. A difference was found between the settings regarding end-of-life care questions and palliative care promotion to relatives., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: Existing estimates of PD prevalence in Denmark are lower than those in the rest of Europe and are based on identification via single registries. Hence, are aim was to use a combined registry/self-report survey approach to identify people with PD and also investigate whether using different registry methods led to differences in the accuracy, completeness and characteristics of the identified cohorts., Methods: This study had a cross-sectional design using routinely collected health registry data to identify adults, ≥18 years of age and resident in Denmark, with PD from either the Danish National Patient (DNP) registry or Danish Prescription Medicines (DPM) registry. Those identified were asked to confirm their PD diagnosis using a national self-report survey., Results: 13,433 people were identified potentially as having PD via the DNP or DPM registry and sent a survey. Of these, 9094 responded (68 %) of which 85 % confirmed they had PD (n = 7763; 194/100,000; 95%CI:7650-7876). When adjusting for non-respondents, assuming an equal rate of confirmation in respondents and non-respondents, estimated Danish PD population was 11,467 (198.4/100,000; 95 % CI:197.2-199.6). Identification of people using those found in both registries led to 98 % confirming they had PD versus using one registry: DNP 93 % and DPM 88 %. No clear differences in sociodemographic characteristics were found between different registry identification methods., Conclusions: Estimated PD population in Denmark was significantly higher than previous Danish estimates and close to existing estimates in other European countries. The most accurate PD population was identified when including those found in both the DNP and DPM registries., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Jette Theusen reports financial support was provided by the Danish Parkinson's Association., (Copyright © 2024.

Turner syndrome (TS) is a chromosomal disorder that affects about 1 in 2500 female births and is characterized by the partial or complete absence of the second X chromosome. Depending on karyotype, TS is associated with primary ovarian insufficiency (POI). Approximately 50% of girls with a mosaic 45, X/46, XX karyotype may enter puberty spontaneously, but only 5-10% of women with TS achieve pregnancy without egg donation. In this review, we will evaluate the clinical use of markers of ovarian function in TS patients. Based on longitudinal studies of serum concentrations of reproductive hormones as well as ovarian morphology in healthy females and patients with TS, we will evaluate how they can be applied in a clinical setting. This is important when counseling patients and their families about future ovarian function essential for pubertal development and fertility. Furthermore, we will report on 20 years of experience of transition from pediatric to gynecological and adult endocrinological care in our center at Rigshospitalet, Copenhagen, Denmark., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Hagen, Fischer, Mola, Mikkelsen, Cleemann, Gravholt, Viuff, Juul, Pedersen and Main.)

Introduction: Equal access to healthcare is a fundamental principle in the fully tax-financed Danish healthcare system. This study reveals whether this system lives up to the principle of equal access when it comes to the rehabilitation of patients who have major lower extremity amputations., Methods: With the aim of exploring possible inequality in rehabilitation for patients having major lower extremity amputation in Denmark, a nationwide electronic survey was conducted in the autumn of 2020, which included all hospitals and municipalities in Denmark., Results: Eighty six percent of hospitals (n = 19) and 97% (n = 95) of municipalities responded. Of the 32% (n = 6) of hospitals and 78% (n = 74) of municipalities that provided prosthesis rehabilitation, the majority (hospitals 50% /municipalities 91%) provided prostheses for <10 patients in 2019, and 36% reported having competencies at only a general level among physiotherapists performing prosthetic training. Psychosocial rehabilitation modalities were lacking overall., Conclusions: This national study documents pronounced geographic inequality in access to qualified rehabilitation services for the relatively few patients undergoing lower extremity amputations in Denmark. The decentralised organisation of amputation rehabilitation makes it difficult to build and maintain specialist competencies among healthcare professionals. Inconsistent availability of psychosocial rehabilitation modalities of all kinds found in this study points to a need for action particularly among patients not in prosthetic rehabilitation where palliative needs should also be considered., (© 2023 The Authors.

Aims: Out-of-hospital cardiac arrest (OHCA) survivors may suffer short-term fatigue, psychological, cognitive and disability problems, but we lack information on the proportion of survivors with these problems in the long-term. Hence, we investigated these problems in survivors 1-5 years post-OHCA and whether the results are different at different time points post-OHCA., Methods: All adults who survived an OHCA in Denmark from 2016 to 2019 were identified using the Danish Cardiac Arrest Registry and invited to participate in a survey between October 2020 and March 2021. The survey included the Modified Fatigue Impact Scale, Hospital Anxiety and Depression Scale, "Two simple questions" (everyday activities and mental recovery), and the 12-item World Health Organisation Disability Assessment Schedule 2.0. To investigate results at different time points, survivors were divided into four time-groups (12-24, 25-36, 37-48 and 49-56 months post-OHCA). Differences between time-groups were determined using the Kruskall-Wallis test for the mean scores and Chi-square test for the proportion of survivors with symptoms., Results: Total eligible survey population was 2116, of which 1258 survivors (60 %) responded. Overall, 29 % of survivors reported fatigue, 20 % anxiety, 15 % depression, and 27 % disability. When survivors were sub-divided by time since OHCA, no significant difference was found on either means scores or proportion between time groups (p = 0.28 to 0.88)., Conclusion: Up to a third of survivors report fatigue, anxiety, depression, reduced mental function and disability 1-5 years after OHCA. This proportion is the same regardless of how much time has passed supporting early screening and tailored post-OHCA interventions to help survivors adapt to their new situation., (Copyright © 2022.

Background: Acute Kidney Injury (AKI) is a frequent and serious postoperative complication in trauma or critically ill patients in the intensive care unit. We aimed to estimate the risk of AKI following major emergency abdominal surgery and the association between AKI and 90-day postoperative mortality., Methods: In this retrospective cohort study, we included patients undergoing major emergency abdominal surgery at the Department of Surgery, Zealand University Hospital, Denmark, from 2010 to 2016. The primary outcome was the occurrence of AKI within postoperative day seven (POD7). AKI was defined according to the Kidney Disease: Improving Global Outcomes (KDIGO)-criteria. The risk of AKI was analysed with a multivariable logistic regression. The association between AKI and 90-day mortality was analysed with a multivariable survival analysis., Results: In the cohort, 122 out of 703 (17.4%) surgical patients had AKI within POD7. Of these, 82 (67.2%) had AKI stage 1, 26 (21.3%) had AKI stage 2, and 14 (11.5%) had AKI stage 3. Fifty-eight percent of the patients who developed postoperative AKI did so within the first 24 h of surgery. Ninety-day mortality was significantly higher in patients with AKI compared with patients without AKI (41/122 (33.6%) versus 40/581 (6.9%), adjusted hazard ratio 4.45 (95% confidence interval 2.69-7.39, P < 0.0001)), and rose with increasing KDIGO stage. Pre-existing hypertension and intraoperative peritoneal contamination were independently associated with the risk of AKI., Conclusions: The risk of AKI is high after major emergency abdominal surgery and is independently associated with the risk of death within 90 days of surgery., (© 2022.

Introduction: The number of out-of-hospital cardiac arrest (OHCA) survivors is increasing. However, there remains limited knowledge on the long-term physical and psychological problems suffered by survivors and their relatives. The aims of the DANCAS (DANish cardiac arrest survivorship) survey are to describe the prevalence of physical and psychological problems, identify predictors associated with suffering them and to determine unmet rehabilitation needs in order to make recommendations on the timing and content of future rehabilitation interventions., Methods and Analysis: The DANCAS survey has a cross-sectional design involving a survey of OHCA survivors and their relatives. OHCA survivors will be identified through the Danish Cardiac Arrest Registry as having suffered an OHCA between 1 January 2016 and 31 December 2019. Each survivor will be asked to identify their closest relative to complete the relatives' survey. Contents of survivor survey: EQ-5D-5Level, Hospital Anxiety and Depression Scale, Two Simple Questions, Modified Fatigue Impact Scale, 12-item WHO Disability Assessment Scale 2.0, plus questions on unmet rehabilitation and information needs. Contents of relatives' survey: World Health Organisation-Five Well-Being Index, Hospital Anxiety and Depression Scale, Informant Questionnaire on Cognitive Decline in the Elderly-Cardiac Arrest and the Modified Caregiver Strain Index. Self-report outcome data collected through the surveys will be enriched by data from Danish national registries including demographic characteristics, circumstances of cardiac arrest and comorbidities. The survey will be completed either electronically or by post December 2020-February 2021., Ethics and Dissemination: The study will be conducted in accordance with the Declaration of Helsinki. Surveys and registry-based research studies do not normally require ethical approval in Denmark. This has been confirmed for this study by the Region of Southern Denmark ethics committee (20192000-19). Results of the study will be disseminated via several peer-reviewed publications and will be presented at national and international conferences., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Head and neck cancer survivors frequently experience nutritional challenges, and proper rehabilitation should be offered. The trial objective was to test the effect of a multidisciplinary residential nutritional rehabilitation programme addressing physical, psychological, and social aspects of eating problems after treatment. In a randomized controlled trial, 71 head and neck cancer survivors recruited through a nationwide survey were randomized to the program or a wait-list control group. Inclusion was based on self-reported interest in participation. The primary outcome was change in body weight. Secondary outcomes included physical function, quality of life, and symptoms of anxiety and depression. Differences between groups at the 3-month follow-up were tested. No significant differences were seen in body weight change, but there were overall trends towards greater improvements in physical function (hand grip strength: p = 0.042; maximal mouth opening: p = 0.072) and quality of life ("Role functioning": p = 0.041; "Speech problems": p = 0.040; "Pain": p = 0.048) in the intervention group. To conclude, a multidisciplinary residential nutritional rehabilitation program had no effect on body weight in head and neck cancer survivors with self-reported interest in participation, but it may have effect on physical function and quality of life. Further research on relevant outcomes, inclusion criteria, and the program's effect in different subgroups is needed.

Background: Eating problems frequently affect quality of life and physical, psychological and social function in patients treated for head and neck cancer (HNC). Residential rehabilitation programmes may ameliorate these adverse effects but are not indicated for all individuals. Systematic assessment of rehabilitation needs may optimise the use of resources while ensuring referral to rehabilitation for those in need. Yet, evidence lacks on which nutrition screening and assessment tools to use. The trial objectives are: 1) To test the effect of a multidisciplinary residential nutritional rehabilitation programme compared to standard care on the primary outcome body weight and secondary outcomes health-related quality of life, physical function and symptoms of anxiety and depression in patients curatively treated for HNC and 2) To test for correlations between participants' development in outcome scores during their participation in the programme and their baseline scores in Nutritional Risk Screening 2002 (NRS 2002), the Scored Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF), and M. D. Anderson Dysphagia Inventory (MDADI) and to assess sensitivity, specificity and predictive values of the three tools in relation to a clinically relevant improvement in outcome scores., Methods: In a randomised controlled trial, 72 patients treated for HNC recruited through a nationwide survey will be randomised to a multidisciplinary residential nutritional rehabilitation programme or to a wait-list control group. Data are collected at baseline, three and six months. Primary outcome is change in body weight, and secondary outcomes include changes in quality of life, physical function and symptoms of anxiety and depression. Potential correlations between intervention effect and baseline scores in NRS 2002, PG-SGA-SF and MDADI will be tested, and sensitivity, specificity and predictive values of the three tools in relation to a clinically relevant improvement in outcome scores will be assessed., Discussion: This is the first randomised controlled trial to test the effect of a multidisciplinary residential nutritional rehabilitation programme in patients treated for HNC. Recruitment through a nationwide survey gives a unique possibility to describe the trial population and to identify potential selection bias. As the trial will explore the potential of different nutrition screening and assessment tools in the assessment of rehabilitation needs in patients treated for HNC, the trial will create knowledge about how selection and prioritisation of nutritional rehabilitation aimed at patients treated for HNC should be offered. The results may contribute to a better organisation and use of existing resources in benefit of patients treated for HNC., Trial Registration: The trial is registered by The Danish Data Protection Agency (registration 2012-58-0018, approval number 18/14847) and the Regional Committees on Health Research Ethics for Southern Denmark (journal number 20182000-165).

Purpose: The purpose of this study was to examine the associations between self-reported spiritual/religious concerns and age, gender, and emotional challenges among cancer survivors who have completed a 5-day rehabilitation course at a rehabilitation center in Denmark (the former RehabiliteringsCenter Dallund (RC Dallund))., Methods: The data stem from the so-called Dallund Scale which was adapted from the NCCN Distress Thermometer and comprised questions to identify problems and concerns of a physical, psychosocial, and spiritual/religious nature. Descriptive statistics were performed using means for continuous variables and frequencies for categorical variables. Odds ratios were calculated by logistic regression., Results: In total, 6640 participants filled in the questionnaire. Among participants, 21% reported one or more spiritual/religious concerns, the most reported concerns related to existence and guilt. Having one or more spiritual/religious concerns was significantly associated with age (OR 0.88), female gender (OR 1.38), and by those reporting emotional problems such as being without hope (OR 2.51), depressed (OR 1.49), and/or anxious (OR 1.95). Among participants, 8% stated they needed help concerning spiritual/religious concerns., Conclusions: Cancer patients, living in a highly secular country, report a significant frequency of spiritual/religious and existential concerns. Such concerns are mostly reported by the young, female survivors and by those reporting emotional challenges. Spiritual/religious and existential concerns are often times tabooed in secular societies, despite being present in patients. Our results call for an increased systemic attention among health professionals to these concerns, and a particular focus on identifying and meeting the spiritual/religious and existential concerns of women, the young and those challenged by hopelessness, depression, and anxiety.

Purpose: The purpose of this qualitative study was twofold: (1) to explore head and neck cancer (HNC) survivors' experiences of everyday life with eating problems after cancer treatment and (2) to explore their experiences of participating in a multidisciplinary residential rehabilitation program with a primary focus on physical, psychological, and social aspects of eating problems after treatment., Methods: Semi-structured focus group interviews were conducted with 40 Danish HNC survivors who participated in a 5-day residential rehabilitation program with follow-up after 3 months. The transcribed interviews were analyzed through qualitative content analysis., Results: Physical nutrition impact symptoms and unmet needs for support were frequent. Participants experienced a feeling of loss due to impaired eating abilities. Eating had become an obligation or a training situation, and the eating problems challenged the relationship with their relatives when well-meaning encouragement was perceived as a pressure. Social eating was a challenge, and this often led to social withdrawal. The residential program was a safe and supportive environment to practice eating skills, and participants benefited from meeting peers. The program provided participants with knowledge and skills that many of them had been missing during and after treatment., Conclusions: Eating problems after treatment have substantial effects on the everyday life of HNC survivors. A multidisciplinary residential rehabilitation program may be beneficial to meet their rehabilitation needs., Implications for Cancer Survivors: The results are useful for future planning of rehabilitation services and clinical studies that may contribute to improving current clinical practice and benefit HNC survivors.

Specialized palliative care (SPC) has a core task in providing palliative care to patients and the families of patients suffering from life-threatening diseases. SPC-units also support the generalist palliative care level. In spring 2016, Denmark had a capacity of 55 units comprising hospices, palliative care teams and palliative hospital wards, which is an insufficient number according to the European Association for Palliative Care recommendations. Despite many non-cancer deaths, 96% of the patients receiving SPC have cancer. The accessibility to SPC is unequally distributed across the regions.

Purpose: Women treated for cervical cancer with radiotherapy and chemotherapy have reported serious bowel, vaginal, and sexual late effects. The purpose of this study was to describe late adverse effects, health-related quality of life, and self-efficacy in a representative Danish cervical cancer population in order to describe rehabilitation needs., Methods: Women, mean age 55 years, treated for cervical cancer from January 2010 to July 2013, who were alive and without known relapse/metastases were included in this cross-sectional study. EORTC QLQ C30 and CX24 and self-efficacy questionnaires were sent to all participants., Results: The participation rate was 85/107 (79%). Participants below 45 years had significantly more menopausal symptoms and lower body image scores compared to elderly women. The frequency of participants with menopausal symptoms decreased with time since diagnosis. Symptom experience was significantly higher in participants with locally advanced disease than in those with local disease. Self-efficacy was significantly lower in participants with locally advanced disease. The incidence of lymphedema was significantly higher among participants who were obese. Multiple analyses showed impaired quality of life, e.g., a lower body image and self-efficacy score, correlated with increasing BMI. Women who had surgery had greater risk of lymphedema, and women who received chemotherapy during treatment had a lower quality of life. All but one received radiotherapy., Conclusion: This study found that young, obese survivors with locally advanced cervical cancer and survivors who received chemotherapy may have a serious risk of developing late adverse effects; thus, rehabilitation should target these needs.

Accumulating evidence suggests that obesity has a negative impact on breast cancer survivors. In this project we developed and tried out a residential 6 + 3 days rehabilitation programme with focus on weight reduction for breast cancer survivors. The key focus was to work with their motivation to change habits by use of cognitive therapy tools. It seems that this residential rehabilitation stay can motivate obese breast cancer survivors to change habits and lose weight. In all the 42 women with complete data lost 6.1 kg in average.

Objective: It has been suggested that vitamin C, alone or in combination with vitamin E, may protect against pre-eclampsia, whereas the safety of high-dose vitamin E supplements has been questioned. We investigated dietary intakes of vitamins C and E to see if they correlated with the incidence of pre-eclampsia., Design: Prospective cohort study., Setting: The Danish National Birth Cohort; a population-based pregnancy cohort; analyses were based on 57 346 pregnancies., Methods: Vitamin intake was estimated from a food frequency questionnaire completed in gestational week 25, recording intake from diet and supplements during the previous four weeks. Pre-eclampsia diagnoses were obtained from the Danish National Patient Registry; we worked with two entities, 'pre-eclampsia (all types)' and 'severe pre-eclampsia/eclampsia/HELLP'. We adjusted for confounding factors by logistic regression., Main Outcome Measures: A small increase in the incidence of severe disease was also seen in the group of women (64, n = 49 373) with a high intake of vitamin E from supplements and dietary sources., Results: The incidence of 'pre-eclampsia (all types)' did not correlate with dietary vitamin C and E intake. There was a decreasing trend (P = 0.01) in the incidence of 'severe pre-eclampsia/eclampsia/HELLP' with increasing dietary vitamin C intake; with an intake of 130-170 mg/day as reference, odds ratios ranged from 1.21 (95% confidence interval 0.83 to 1.75) for an intake below 70 mg/day to 0.70 (0.40 to 1.23) for an intake exceeding 275 mg/day (total n = 57 346). For vitamin E intake aggregated from diet and supplements (n = 49 373), with an intake of 10.5-13.5 mg/day as reference, the 'severe pre-eclampsia/eclampsia/HELLP' odds ratio was 1.46 (1.02 to 2.09) for an intake exceeding 18 mg/day., Conclusions: Low dietary intake of vitamin C was associated with a trend towards an increased incidence of either severe pre-eclampsia, eclampsia or HELLP. A small increase in the incidence of severe disease was also seen in the group of women with a high intake of vitamin E from supplements and dietary sources.

Objectives: To investigate possible associations between maternal diet during pregnancy and fetal growth., Method: Factor analysis was used to explore dietary patterns among pregnant women. The association between maternal dietary patterns and fetal growth (in terms of small for gestational age, SGA) was investigated by logistic regression. Prospective cohort study, including information on 44 612 women in Denmark., Results: Two major dietary patterns were defined: the first pattern was characterized by red and processed meat, high-fat dairy, and the second pattern was characterized by intake of vegetables, fruits, poultry and fish. Women were classified into three classes according to their diet: the first class had high intake of foods of the first dietary pattern, and was classified as 'the Western diet', the second class preferred foods of the second pattern and was classified as the 'Health Conscious'; and the third one had eaten foods of both patterns, and was classified as the 'Intermediate'. The odds ratio of having a small for gestational-age infant (with a birth weight below the 2.5th percentile for gestational age and gender) was 0.74 (95% CI 0.64-0.86) for women in the Health Conscious class compared with women in the Western Diet class. The analyses were adjusted for parity, maternal smoking, age, height, pre-pregnancy weight and father's height., Conclusions: Our results indicated that a diet in pregnancy, based on red and processed meat and high-fat diary, was associated with increased risk for SGA. Further studies are warranted to identify specific macro-, or micronutrients that may be underlying these associations.

Background: Thus far, few factors with a causal relation to preterm birth have been identified. Many studies have focused on the woman's diet, but most have been discouraging. The aim of the present study was to examine if maternal intake of a Mediterranean-type diet (MD) is associated with reduced risk of preterm birth., Methods: The Danish National Birth Cohort assessed diet in mid-pregnancy by food frequency questionnaires (FFQ). Women consuming MD were those who ate fish twice a week or more, used olive or rape seed oil, consumed 5+ fruits and vegetables a day, ate meat (other than poultry and fish) at most twice a week, and drank at most 2 cups of coffee a day., Results: Of 35,530 non-smoking women, 1,137 (3.2%) fulfilled all MD criteria, and 540 (1.5%) none. Odds ratios for preterm birth and early preterm birth were 0.61 (95% Confidence Interval (CI): 0.35-1.05) and 0.28 (0.11-0.76), respectively, in MD women compared to women fulfilling none of the MD criteria., Conclusion: Shifting towards a MD during pregnancy may reduce the risk of early delivery in Danish women.

Background: Cow milk contains many potentially growth-promoting factors., Objective: The objective was to examine whether milk consumption during pregnancy is associated with greater infant size at birth., Design: During 1996-2002, the Danish National Birth Cohort collected data on midpregnancy diet through questionnaires and on covariates through telephone interviews and ascertained birth outcomes through registry linkages. Findings were adjusted for mother's parity, age, height, prepregnant BMI, gestational weight gain, smoking status, and total energy intake; father's height; and family's socioeconomic status The analyses included data from 50,117 mother-infant pairs., Results: Mean (+/-SD) consumption of milk was 3.1 +/- 2.0 glasses/d. Milk consumption was inversely associated with the risk of small-for gestational age (SGA) birth and directly with both large-for-gestational age (LGA) birth and mean birth weight (P for trend < 0.001). In a comparison of women drinking >or=6 glasses/d with those drinking 0 glasses/d, the odds ratio for SGA was 0.51 (95% CI: 0.39, 0.65) and for LGA was 1.59 (1.16, 2.16); the increment in mean birth weight was 108 g (74, 143 g). We also found graded relations (P < 0.001) for abdominal circumference (0.52 cm; 0.35, 0.69 cm), placental weight (26 g; 15, 38 g), birth length (increment: 0.31 cm; 0.15, 0.46 cm), and head circumference (0.13 cm; 0.04, 0.25 cm). Birth weight was related to intake of protein, but not of fat, derived from milk., Conclusion: Milk intake in pregnancy was associated with higher birth weight for gestational age, lower risk of SGA, and higher risk of LGA.

Objective: To validate the fruit and vegetable intake estimated from the Food Frequency Questionnaire (FFQ) used in the Danish National Birth Cohort (DNBC)., Subjects and Setting: The DNBC is a cohort of 101,042 pregnant women in Denmark, who received a FFQ by mail in gestation week 25. A validation study with 88 participants was made. A seven-day weighed food diary (FD) and three different biomarkers were employed as comparison methods., Results: Significant correlations between FFQ and FD-based estimates were found for fruit (r = 0.66); vegetables (r = 0.32); juice (r = 0.52); fruit and vegetables (F&V) (r = 0.57); and fruit, vegetables, and juice (F&V&J) (r = 0.62). Sensitivities of correct classification by FFQ into the two lowest and the two highest quintiles of F&V&J intake were 58-67% and 50-74%, respectively, and specificities were 71-79% and 65-83%, respectively. F&V&J intake estimated from the FFQ correlated significantly with urinary flavonoids (r = 0.39, p<0.005), plasma beta-carotene (r = 0.21, p<0.05) and erythrocyte folate (r = 0.33, p<0.005); all average biomarker levels increased across increasing quintiles of F&V&J intake., Conclusion: Data on F&V&J recorded by FFQ in DNBC can be used in etiological analyses of associations between fruit and vegetable intake and health outcomes, provided that the potential misclassification of dietary exposure is kept in mind.

Recent research suggests that the diet consumed in, or shortly before, pregnancy can potentially lead to maldevelopment and diseases in the offspring, which may become apparent at any time from the embryonic stage until old age. For example, maternal diet may affect the chance of twinning (and associated complications), malformation risk, brain development, and the offspring's fecundity and risk of contracting cardiovascular diseases and cancer in adult life. Prospectively designed longitudinal studies with sufficient size and data quality are much needed to substantiate or refute these hypotheses. At present, the Danish National Birth Cohort is likely to be the largest epidemiological database containing extensive information on maternal dietary exposures. By October 2002, 100 000 women had been recruited in early pregnancy, for long-term follow-up of themselves and their offspring. The present paper details the information available in the database on early nutritional exposures with emphasis on maternal dietary intake. We also present distributions of selected nutritional exposures.

Background: Atopic dermatitis has been related to a disturbed metabolism of polyunsaturated fatty acids (PUFAs)., Objective: We tested whether the PUFA composition of breast milk differs significantly between mothers with atopic dermatitis, mothers with other types of atopy, and nonatopic mothers. We also investigated whether differences in diet can explain possible observed differences., Design: Mothers with current or previous asthma (n = 396) were divided into 3 groups according to history of atopic dermatitis and allergic rhinitis. Breast-milk samples were collected from 314 women approximately 3 wk after delivery. The habitual diet of the women was assessed with food-frequency questionnaires in the 25th week of gestation (n = 207). Breast-milk samples and simultaneous dietary data from 14 nonatopic mothers were used for comparison., Results: Compared with the milk of nonatopic mothers, that of atopic mothers had significantly higher concentrations of 22:5n-6 and lower concentrations of 20:5n-3; moreover, 20:4n-6/20:5n-3, 22:5n-6/22:6n-3, and long-chain n-3 PUFA/18:3n-3 were shifted toward n-6 PUFA and 18:3n-3 in nonatopic and atopic mothers, respectively. No differences in breast-milk PUFA composition were evident between the subject groups. The diets of the groups differed only slightly with respect to protein intake. However, the PUFA composition of the breast milk was associated with diet and time of milk sampling, and the above difference in milk PUFAs disappeared when those factors were taken into account., Conclusion: Our data do not support the possibility that the fatty acid composition of breast milk is affected by atopic dermatitis or atopy in general, because most differences in breast-milk PUFA composition appear to be explained by the diet.

Objectives: To test the earlier suggested hypothesis that intake of long-chain n-3 fatty acids from fish oil may delay the timing of spontaneous delivery and to test if alpha-linolenic acid, provided as flax oil capsules, shows the same effect., Design: Randomised controlled trial including women reporting low dietary fish intake. The women were allocated in the proportions of 1:1:1:1:1:1:2 into six treatment groups and a control group, respectively, from week 17-27 of gestation. The treatment groups received fish oil, in various doses, or flax oil, and the control group did not receive any treatment., Setting: The Danish National Birth Cohort., Sample: A total of 3098 women allocated into six treatment groups and one control group., Methods: The six intervention groups were offered fish oil capsules in doses of 0.1, 0.3, 0.7, 1.4 and 2.8 g of eicosapentaenoic acid and docosahexaenoic acid per day or 2.2 g of alpha-linolenic acid (ALA) per day from week 17-27 of gestation until delivery., Main Outcome Measures: Timing of spontaneous delivery., Results: No differences in timing of spontaneous delivery was detected in the fish oil groups or the flax oil group, compared with the control group. The difference in timing of spontaneous delivery in the group receiving the highest fish oil dose compared with the control group was 0.8 days (95% CI: -2.3 to 1.0). Only a minority of the women in the intervention groups took capsules until delivery., Conclusion: Possible explanations for these findings include no true effect of n-3 fatty acids on spontaneous delivery or a quick-acting effect not detectable in this trial.

Background: In the literature pica is reported to be prevalent in pregnant women. Most studies have focused on less privileged populations, but is pica prevalent among privileged pregnant women?, Methods: 100,000 pregnant women in the Danish National Birth Cohort were asked about pica in a food frequency questionnaire mailed in gestation week 25., Results: The response rate of the questionnaire was 70% of Danish National Birth Cohort participants. Only 14 women reported to have eaten substances that were clearly not foods, i.e. 0.02% had pica in this cohort of well nourished Danish women., Conclusion: It seems that, in privileged populations, pica is more a myth than a reality.

Objective: To examine whether fruit and vegetable consumption in pregnancy is associated with birth weight in a Western population., Design: Prospective cohort study based on telephone interviews, a food frequency questionnaire (FFQ), and extractions of birth characteristics from national health registries., Subjects and Setting: The 43,585 Danish women from the Danish National Birth Cohort who had completed the FFQ in mid-pregnancy and on whom information about birth outcome was available. The exposures were frequency of green leafy vegetable (GLV) intake and quantified intake of fruit, fruit and vegetables, and fruit and vegetables and juice. The outcomes were birth weight and z-score for expected birth weight adjusted for sex and gestation week. Information on maternal height, weight, smoking, and other potential confounders was obtained through telephone interviews., Results: Significant associations were found for all exposures to fruit and vegetable intake with birth weight and most with z-score. The strongest association was found for fruit intake in which case birth weight increased by 10.7 g (95% CI 7.3-14.2) per quintile. All associations were stronger among lean women (BMI<20, n = 7,169), whose children's birth weight increased by 14.6 g (95% CI 6.4-22.9) per quintile increase in fruit intake. For GLV the results were more inconclusive. When adjusted for confounders, but not for energy, the association between GLV and birth weight was significant, but the same was not the case for z-score., Conclusion: Fruit and vegetable consumption in pregnancy is positively associated with birth weight in well-nourished Danish women, especially among lean women.

Studies on formula-fed infants indicate a beneficial effect of dietary DHA on visual acuity. Cross-sectional studies have shown an association between breast-milk DHA levels and visual acuity in breast-fed infants. The objective in this study was to evaluate the biochemical and functional effects of fish oil (FO) supplements in lactating mothers. In this double-blinded randomized trial, Danish mothers with habitual fish intake below the 50th percentile of the Danish National Birth Cohort were randomized to microencapsulated FO [1.3 g/d long-chain n-3 FA (n-3 LCPUFA)] or olive oil (OO). The intervention started within a week after delivery and lasted 4 mon. Mothers with habitual high fish intake and their infants were included as a reference group. Ninety-seven infants completed the trial (44 OO-group, 53 FO-group) and 47 reference infants were followed up. The primary outcome measures were: DHA content of milk samples (0, 2, and 4 mon postnatal) and of infant red blood cell (RBC) membranes (4 mon postnatal), and infant visual acuity (measured by swept visual evoked potential at 2 and 4 mon of age). FO supplementation gave rise to a threefold increase in the DHA content of the 4-mon milk samples (P < 0.001). DHA in infant RBC reflected milk contents (r = 0.564, P < 0.001) and was increased by almost 50% (P < 0.001). Infant visual acuity was not significantly different in the randomized groups but was positively associated at 4 mon with infant RBC-DHA (P = 0.004, multiple regression). We concluded that maternal FO supplementation during lactation did not enhance visual acuity of the infants who completed the intervention. However, the results showed that infants with higher RBC levels of n-3 LCPUFA had a better visual acuity at 4 mon of age, suggesting that n-3 LCPUFA may influence visual maturation.
