Many adolescents worldwide (indirectly) grow up with a chronic disease, which may impact their functioning and wellbeing. The objective of this study is to assess whether adolescents with a (family member with a) chronic disease differ from their healthy counterparts in terms of psychosocial functioning. Data from the Dutch 2013 HBSC-survey were used, including 7168 adolescents (Meanage = 13.7, SD = 1.57, 50.5% female). Participants indicated whether they or one of their family members had a long-term (> 3 months) disease or disability (mental/physical) and were categorized into four groups based on disease presence (none, other, self, both). Psychosocial functioning was assessed in terms of life satisfaction, self-rated health, psychosomatic health, mental health problems, support, substance use, physical exercise, screen time, and school liking. Chronically diseased adolescents (n = 162) reported lower life satisfaction, self-rated and psychosomatic health, more mental health problems, lower peer support, more substance use, and less physical exercise compared to healthy peers. Chronically diseased adolescents who also had a family member with a chronic disease (n = 74) showed comparable outcomes on these life domains, although they did not differ from their healthy peers regarding peer support, substance use, and physical activity. Healthy adolescents with a chronically diseased family member (n = 737) reported significantly lower life satisfaction, self-rated and psychosomatic health, more mental health problems, and less family support compared to healthy peers who grew up in healthy families; however, they reported more positive outcomes than adolescents who had a chronic disease themselves. Conclusion: Having a (family member with a) chronic disease is associated with impaired psychosocial functioning on various life domains. Our findings aid in understanding the psychosocial associates of chronic disease and imply that caregivers should be observant of psychosocial problems among vulnerable adolescents to provide appropriate guidance. What is Known: • Adolescents who grow up with a (family member with a) chronic disease encounter numerous challenges that may be related to poorer developmental outcomes on the long term. What is New: • This study adds a comprehensive overview of the psychosocial functioning of adolescents with a (family member with a) chronic disease, as compared to healthy counterparts that grow up in a healthy family.

Objective: Women with heart failure with reduced ejection fraction (HFrEF) may reach optimal treatment effect at half of the guideline-recommended medication dose. This study investigates prescription practice and its relation with survival of patients with HF in daily care.Methods: Electronic health record data from 13 Dutch outpatient cardiology clinics were extracted for HF receiving at least one guideline-recommended HF medication. Dose changes over consecutive prescriptions were modelled using natural cubic splines. Inverse probability-weighted Cox regression was used to assess the relationship between dose (reference≥50% target dose) and all-cause mortality.Results: The study population comprised 561 women (29% HFrEF (ejection fraction (EF)<40%), 49% heart failure with preserved ejection fraction (EF≥50%); HFpEF and 615 men (47% and 25%, respectively). During a median follow-up of 3.7 years, 252 patients died (48% women; 167 HFrEF, 84 HFpEF). Nine hundred thirty-four patients (46% women) received ACE inhibitors (ACEIs) or angiotensin receptor blockers (ARBs), 795 (48% women) beta blockers and 178 (42% women) mineralocorticoid receptor antagonists (MRAs). In both sexes, the mean target dose across prescriptions was 50% for ACEI/ARBs and beta blockers, and 100% for MRAs. ACEI/ARB dose of <50% was associated with lower mortality in women but not in men with HFrEF. This was not seen in patients with HFpEF. Beta-blocker dose was not associated with all-cause mortality.Conclusion: Patients with HF seen in outpatient cardiology clinics receive half of the guideline-recommended medication dose. Lower ACEI/ARB dose was associated with improved survival in women with HFrEF. These results underscore the importance of (re)defining optimal medical therapy for women with HFrEF.

Background: Despite the increasing availability of clinical data due to the digitalisation of healthcare systems, data often remain inaccessible due to the diversity of data collection systems. In the Netherlands, Cardiology Centers of the Netherlands (CCN) introduced "one-stop shop" diagnostic clinics for patients suspected of cardiac disease by their general practitioner. All CCN clinics use the same data collection system and standardised protocol, creating a large regular care database. This database can be used to describe referral practices, evaluate risk factors for cardiovascular disease (CVD) in important patient subgroups, and develop prediction models for use in daily care.Construction and Content: The current database contains data on all patients who underwent a cardiac workup in one of the 13 CCN clinics between 2007 and February 2018 (n = 109,151, 51.9% women). Data were pseudonymised and contain information on anthropometrics, cardiac symptoms, risk factors, comorbidities, cardiovascular and family history, standard blood laboratory measurements, transthoracic echocardiography, electrocardiography in rest and during exercise, and medication use. Clinical follow-up is based on medical need and consisted of either a repeat visit at CCN (43.8%) or referral for an external procedure in a hospital (16.5%). Passive follow-up via linkage to national mortality registers is available for 95% of the database.Utility and Discussion: The CCN database provides a strong base for research into historically underrepresented patient groups due to the large number of patients and the lack of in- and exclusion criteria. It also enables the development of artificial intelligence-based decision support tools. Its contemporary nature allows for comparison of daily care with the current guidelines and protocols. Missing data is an inherent limitation, as the cardiologist could deviate from standardised protocols when clinically indicated.Conclusion: The CCN database offers the opportunity to conduct research in a unique population referred from the general practitioner to the cardiologist for diagnostic workup. This, in combination with its large size, the representation of historically underrepresented patient groups and contemporary nature makes it a valuable tool for expanding our knowledge of cardiovascular diseases.Trial Registration: Not applicable.

Aims: To assess the prevalence rates and risk factors of anterior disc displacement with reduction (ADDR) and symptomatic hypermobility in a large sample of children and teenagers. Prevalence rates were also established in samples of young adults and adults. Methods: Children from 7 Dutch primary and secondary schools (n = 1,833) aged 4 to 18 years (mean age ± SD 10.8 ± 3.9 years), 220 dental students aged 19 to 30 years (mean age ± SD 21.9 ± 3.6 years), and 100 dental school employees more than 30 years old (mean age ± SD 43.5 ± 9.8 years) were examined. The presence of ADDR or symptomatic hypermobility was scored using well-defined clinical criteria. For the children only, an additional standardized oral history and clinical examination were performed to assess possible risk factors. Odds ratios (ORs) were calculated with the use of logistic multivariate regression analysis. Results: The prevalence rate of ADDR in at least 1 of the 2 joints increased during childhood and adolescence and stabilized into adulthood at about 26.6%. In children and teenagers, besides age (OR = 1.06 for boys, OR = 1.23 for girls), risk factors for ADDR were a history of orthodontics (OR = 1.57), an increasing overbite (OR = 1.15), and protrusion (OR = 1.12). In children and teenagers, the prevalence rate of symptomatic hypermobility was higher for girls (13.8%) than for boys (8.2%). Besides gender (OR = 2.07), risk factors for symptomatic hypermobility were race (OR = 2.61 for non-Caucasians), masticatory muscle pain (OR = 1.95), and increasing maximum mouth opening (OR = 1.08). Conclusion: In children and teenagers, ADDR and symptomatic hypermobility have different prevalence rates and risk factors. [ABSTRACT FROM AUTHOR]

Background: A healthy diet is important for normal growth and development. Exposure to undernutrition during important developmental periods such as childhood and adolescence can have effects later in life. Inhabitants of the west of the Netherlands were exposed to severe undernutrition during the famine in the last winter of the second World War (1944–1945). Objective: We investigated if exposure of women to the Dutch famine during childhood and adolescence was associated with an unhealthy lifestyle later in life. Design: We studied 7,525 women from the Prospect-EPIC cohort, recruited in 1993–97 and aged 0–18 years during the Dutch famine. An individual famine score was calculated based on self-reported information about experience of hunger and weight loss. We investigated the association between famine exposure in early life and four lifestyle factors in adulthood: smoking, alcohol consumption, physical activity level and a Mediterranean-style diet. Results: Of the 7,525 included women, 46% were unexposed, 38% moderately exposed and 16% severely exposed to the Dutch famine. Moderately and severely exposed women were more often former or current smokers compared to women that did not suffer from the famine: adjusted prevalence ratio 1.10 (95% CI: 1.05; 1.14) and 1.18 (1.12; 1.25), respectively. They also smoked more pack years than unexposed women. Severely exposed women were more often physically inactive than unexposed women, adjusted prevalence ratio 1.32 (1.06; 1.64). Results did not differ between exposure age categories (0–9 and 10–17 years). We found no associations of famine exposure with alcohol consumption and no dose-dependent relations with diet. Conclusions: Exposure to famine early in female life may be associated with higher prevalence of smoking and physical inactivity later in life, but not with unhealthy diet and alcohol consumption.

ObjectiveTo examine the association between adherence to the Dutch Guidelines for a Healthy Diet created by the Dutch Health Council in 2006 and overall and smoking-related cancer incidence.DesignProspective cohort study.SettingAdherence to the guidelines, which includes one recommendation on physical activity and nine on diet, was measured using an adapted version of the Dutch Healthy Diet (DHD) index. The score ranged from 0 to 90 with a higher score indicating greater adherence to the guidelines. We estimated the hazard ratios (HR) and 95 % confidence intervals for the association between the DHD index (in tertiles and per 20-point increment) at baseline and cancer incidence at follow-up.SubjectsWe studied 35 608 men and women aged 20–70 years recruited into the European Prospective Investigation into Cancer and Nutrition–Netherlands (EPIC-NL) study during 1993–1997.ResultsAfter an average follow-up of 12·7 years, 3027 cancer cases were documented. We found no significant association between the DHD index (tertile 3 v. tertile 1) and overall (HR = 0·97; 95 % CI 0·88, 1·07) and smoking-related cancer incidence (HR = 0·89; 95 % CI 0·76, 1·06) after adjustment for relevant confounders. Excluding the components physical activity or alcohol from the score did not change the results. None of the individual components of the DHD index was significantly associated with cancer incidence.ConclusionsIn the present study, participants with a high adherence to the Dutch Guidelines for a Healthy Diet were not at lower risk of overall or smoking-related cancer. This does not exclude that other components not included in the DHD index may be associated with overall cancer risk. [ABSTRACT FROM AUTHOR]

Background: Although diet is related to chronic disease risk and mortality, its association with total disease burden is not clear. Objective: We investigated the minimum impact of different dietary patterns on disability-adjusted life years (DALYs) by using individual longitudinal data. Design: A prospective cohort study was conducted in 33,066 healthy men and women aged 20-70 y recruited into the European Prospective Investigation into Cancer and Nutrition-Netherlands study during 1993-1997. We measured adherence to 3 a priori dietary patterns [the modified Mediterranean diet score (mMDS), the WHO-based Healthy Diet Indicator, and the Dutch Healthy Diet index] and 2 a posteriori dietary patterns. Two a posteriori methods were used to extract Western and prudent patterns. Participants were followed until the end of 2007 for the occurrence of and mortality from the most important chronic diseases. The disease burden was expressed in DALYs, which are the sum of Years Lost due to Disability and Years of Life Lost because of premature mortality. The associations between dietary patterns (per SD change in score) and DALYs were estimated by using a 2-part model and adjusted for relevant confounders (sex, age at recruitment, smoking status and intensity, educational level, marital status, job status, energy intake, and physical activity). Results: After an average follow-up of 12.4 y, higher adherence to the mMDS or prudent pattern was most strongly associated with healthy survival; per SD higher adherence to the mMDS or prudent pattern, fewer healthy life years were lost [51 d (-0.14 DALYs; 95% CI: -0.21, -0.08 DALYs) and 58 d (-0.16 DALYs; 95% CI: -0.23, -0.09 DALYs), respectively]. Conclusion: In this Dutch study, of various dietary patterns evaluated, higher adherence to the mMDS or prudent dietary pattern was associated with a lower disease burden as assessed by DALYs.

Objective To determine the levels of thymic stromal lymphopoietin (TSLP) and the numbers of TSLP receptor (TSLPR)-expressing CD1c+ (blood dendritic cell antigen 1-positive) myeloid dendritic cells (MDCs) in the joints as compared with the peripheral blood (PB) of patients with rheumatoid arthritis (RA), as well as to determine the capacity of TSLP to induce MDC-dependent T cell activation. Methods TSLP levels were measured in synovial fluid (SF) samples from patients with RA and those with osteoarthritis (OA). MDC numbers in PB and SF samples from RA patients and TSLPR expression on these cells were assessed by fluorescence-activated cell sorter analysis. PB and SF MDCs from RA patients were stimulated with TSLP, and cytokine production was measured by multiplex immunoassay. TSLP-primed MDCs were cocultured with autologous CD4+ T cells in the absence of additional stimuli, and subsequently, cell proliferation and cytokine production were measured. Results TSLP levels were significantly increased in SF samples from RA versus OA patients. The numbers of TSLPR-expressing MDCs in the SF of RA patients were significantly increased as compared to those in the PB, and SF MDCs displayed increased levels of TSLPR. TSLP selectively stimulated the production of thymus and activation-regulated chemokine and macrophage inflammatory protein 1α by CD1c+ MDCs. TSLP-primed MDCs from PB and SF potently stimulated the proliferation of autologous CD4+ T cells as compared to unstimulated MDCs. Enhanced proliferation was associated with increased production of interferon-γ, interleukin-17 (IL-17), and IL-4. Conclusion These data support an inflammatory mechanism by which increased intraarticular TSLP in RA potently activates TSLPR-expressing CD1c+ MDCs in the joints to secrete chemokines, causing chemotaxis and subsequent activation of CD4+ T cells. In addition to the demonstrated inflammatory potential of TSLP in experimental arthritis, this suggests that TSLP and TSLPR-expressing MDCs could both play a pivotal role in the immunopathology of RA.

Purpose: Although overweight is an important determinant of diabetes risk, it remains unclear whether food choices can still influence the risk for type 2 diabetes in overweight persons. In this paper, we aim to clarify the role of dietary patterns in the development of type 2 diabetes in overweight and obese individuals. Methods: We studied 20,835 overweight and obese participants in the Dutch part of the European Investigation into Cancer and Nutrition (EPIC-NL) study. Dietary intake was measured using a validated food frequency questionnaire, and dietary patterns were generated using factor analysis. Incident type 2 diabetes was verified against medical records. Cox proportional hazards models were used to assess the association between the dietary patterns (factor scores categorized in quartiles) and incident type 2 diabetes. Results: Scoring on Pattern 1, characterized by fish, wine, chicken, raw vegetables and fruit juices, was not associated with type 2 diabetes risk after confounder adjustment. A high score on Pattern 2, characterized by soft drinks, fries and snacks, was associated with higher risk of type 2 diabetes (HR Q4 vs. Q1 (95 % CI): 1.70 (1.31; 2.20), p ≤ 0.0001), particularly among less active individuals [less active: HR Q4 vs. Q1 (95 % CI): 2.14 (1.48; 3.09), p = 0.00004, more active: HR Q4 vs. Q1 (95 % CI): 1.35 (0.93; 1.97), p = 0.01; p = 0.02]. Conclusions: A high score on a pattern high in soft drinks, fries and snacks and low in fruit and vegetables was associated with higher risk of type 2 diabetes in overweight and obese subjects especially among physically less active individuals.

Objective. To study the phenotypic characteristics of and the balance between systemic IL-7 receptor (IL-7R)α+ and IL-7Rα− Tregs in primary SS (pSS) patients as compared with control subjects and to assess the functional consequences this has for (IL-7-induced) T-cell activation.Methods. The functional properties of IL-7Rα+ and IL-7Rα−(CD25+) CD4 T cells from pSS patients were tested in vitro. Expression of CD25 and FoxP3 by IL-7Rα+ and IL-7Rα−CD4 T cells from pSS patients and healthy controls (HCs) were assessed. Also, the net ex vivo T-cell cytokine production and the capacity of IL-7 to activate total CD4 T cells from pSS patients compared with HCs in vitro was tested.Results. IL-7Rα+ T cells from pSS patients strongly proliferated and their numbers were slightly reduced compared with HCs. This reduced number was caused by an increase in both anergic and suppressive IL-7Rα−CD25+ T cells expressing high levels of FoxP3, but also by increases in IL-7Rα−CD25− CD4 T cells that only moderately expressed FoxP3. This altered balance in IL-7Rα+ and IL-7Rα−CD4 T cells was accompanied by unchanged ex vivo Th1, Th2 and Th17 cytokine production of total CD4 T cells. Furthermore, the increased numbers of IL-7Rα−CD25+ T cells did not prevent specific IL-7-induced Th1 and Th17 cytokine production by IL-7Rα+ T cells.Conclusion. IL-7Rα+ cells are highly proliferating cells that respond strongly to IL-7 despite an increased number of IL-7Rα− T cells that express FoxP3 and CD25. The recent finding that IL-7 and IL-7Rα+ T cells were both found to be increased in exocrine glands of pSS patients indicates that IL-7 could contribute to glandular inflammation by activation of IL-7Rα+ responder T cells despite the increased numbers of Tregs.

Background: Genome-wide association studies in Japanese populations recently identified common variants in the KCNQ1 gene to be associated with type 2 diabetes. We examined the association of these variants within KCNQ1 with type 2 diabetes in a Dutch population, investigated their effects on insulin secretion and metabolic traits and on the risk of developing complications in type 2 diabetes patients. Methodology: The KCNQ1 variants rs151290, rs2237892, and rs2237895 were genotyped in a total of 4620 type 2 diabetes patients and 5285 healthy controls from the Netherlands. Data on macrovascular complications, nephropathy and retinopathy were available in a subset of diabetic patients. Association between genotype and insulin secretion/action was assessed in the additional sample of 335 individuals who underwent a hyperglycaemic clamp. Principal Findings: We found that all the genotyped KCNQ1 variants were significantly associated with type 2 diabetes in our Dutch population, and the association of rs151290 was the strongest (OR 1.20, 95% CI 1.07-1.35, p = 0.002). The risk Callele of rs151290 was nominally associated with reduced first-phase glucose-stimulated insulin secretion, while the non-risk T-allele of rs2237892 was significantly correlated with increased second-phase glucose-stimulated insulin secretion (p = 0.025 and 0.0016, respectively). In addition, the risk C-allele of rs2237892 was associated with higher LDL and total cholesterol levels (p = 0.015 and 0.003, respectively). We found no evidence for an association of KCNQ1 with diabetic complications. Conclusions: Common variants in the KCNQ1 gene are associated with type 2 diabetes in a Dutch population, which can be explained at least in part by an effect on insulin secretion. Furthermore, our data suggest that KCNQ1 is also associated with lipid metabolism. [ABSTRACT FROM AUTHOR]

Context. Acute intoxications are frequently seen in Dutch hospitals. Based on single-centre studies and the fact that there are no clear guidelines, we hypothesised that hospital admission of acute intoxications may vary. Furthermore, decontamination treatment of poisonings may differ between hospitals, as earlier studies showed that adherence to international guidelines concerning decontamination may be poor. Objective. We aim to identify possible variations in Dutch hospital admission and decontamination treatment of patients with acute intoxications. Materials and methods. Data on acute intoxications was retrospectively collected from patient records from the emergency departments of six Dutch hospitals. All patients older than 14 years who presented between 1 January 2008 and 31 December 2008 were included in the study. Results. The percentage of suicide attempts differed significantly between the hospitals (25-73%, p < 0.0001) as equally the percentage of intoxications with drugs of abuse (18-61%, p < 0.0001). Marked differences in admission rates were found (27-78%, p < 0.0001) and these differences remained even when intoxications because of suicide attempts and drugs of abuse were analysed separately (admission rate of 52-87%, p < 0.0001 and 8-71%, p < 0.0001 respectively). Reported consultation with the National Poisons Information Centre differed between hospitals (range 0% to 80-100%). No statistical differences were found between hospitals for the use of activated charcoal (16.1-42.5%, p == 0.037). Gastric lavage was used infrequently in all hospitals. (6.6-16.7%, p == 0.614). Discussion and conclusion. The admission rate of patients with an acute intoxication varies considerably, especially in the case of intoxications with drugs of abuse. Consultations with the National Poisons Information Centre differed between the six hospitals. Rates of decontamination did not vary, which may indicate adherence to guidelines by the American Academy of Clinical Toxicology, European Association of Poisons Centres and Clinical Toxicologists. National guidelines or admission algorithms may reduce variations in poisoning management and make the care for these patients more efficient. [ABSTRACT FROM AUTHOR]

Parity, oral contraceptive use, and hysterectomy are known to protect against ovarian cancer, whereas the effect of other reproductive factors remains unclear. The authors investigated the association between several reproductive and hormonal factors and the risk of epithelial invasive ovarian cancer among postmenopausal women participating in the Netherlands Cohort Study on Diet and Cancer. Information on reproductive history and exogenous hormone use was obtained through a self-administered questionnaire at baseline in 1986. After 16.3 years of follow-up, 375 cases and 2,331 subcohort members were available for case-cohort analysis. Ovarian cancer risk was reduced for parous women, with increasing parity, and for hysterectomized women. Moreover, the authors found evidence that oral contraceptive use is protective against ovarian cancer, even when initiated at an older age. In addition, a reduced risk was observed for each year reduction in age at natural menopause and per year reduction in total menstrual life span. A small increased risk was observed with prolonged time to pregnancy, but no difference was found between ever-married nulliparous women and never-married nulliparous women. Moreover, no associations were observed for age at first birth, age at menarche, age at first and last use of oral contraceptives, and use of hormone replacement therapy. [ABSTRACT FROM PUBLISHER]

We investigated whether the 1944-1945 Dutch famine has affected postmenopausal sex hormone concentrations with data from 163 women (young adults during the famine). Urinary sex hormone concentrations showed modest elevations with increasing famine exposure. Effects were absent in parous women, but more pronounced in women who had never given birth.British Journal of Cancer (2004) 90, 115-117. doi:10.1038/sj.bjc.6601513 www.bjcancer.com [ABSTRACT FROM AUTHOR]

Angina without angiographic evidence of obstructive coronary artery disease (ANOCA) is a highly prevalent condition with insufficient pathophysiological knowledge and lack of evidence-based medical therapies. This affects ANOCA patients prognosis, their healthcare utilization and quality of life. In current guidelines, performing a coronary function test (CFT) is recommended to identify a specific vasomotor dysfunction endotype. The NetherLands registry of invasive Coronary vasomotor Function testing (NL-CFT) has been designed to collect data on ANOCA patients undergoing CFT in the Netherlands. The NL-CFT is a web-based, prospective, observational registry including all consecutive ANOCA patients undergoing clinically indicated CFT in participating centers throughout the Netherlands. Data on medical history, procedural data and (patient reported) outcomes are gathered. The implementation of a common CFT protocol in all participating hospitals promotes an equal diagnostic strategy and ensures representation of the entire ANOCA population. A CFT is performed after ruling out obstructive coronary artery disease. It comprises of both acetylcholine vasoreactivity testing as well as bolus thermodilution assessment of microvascular function. Optionally, continuous thermodilution or Doppler flow measurements can be performed. Participating centers can perform research using own data, or pooled data will be made available upon specific request via a secure digital research environment, after approval of a steering committee. NL-CFT will be an important registry by enabling both observational and registry based (randomized) clinical trials in ANOCA patients undergoing CFT. • NL-CFT is a web-based, prospective, observational registry. • All consecutive ANOCA patients undergoing clinically indicated CFT are included. • NL-CFT enables both observational and registry based (randomized) clinical trials.

Objectives: To examine if age-specific anti-Müllerian hormone (AMH) levels are associated with cancer risk; and to investigate if age-related AMH trajectories differ between women who develop cancer and women who do not. More specifically, we examined associations with breast cancer, cancers in other tissues expressing AMH receptor AMHR2, and cancers in non-AMHR2-expressing tissues.Study Design: We included longitudinal data from 3025 women in the prospective Doetinchem Cohort Study. Cox proportional hazards models were used to assess the association of baseline age-specific AMH tertiles with cancer. We applied linear mixed models to compare age-related AMH trajectories between women who were diagnosed with cancer and women who were not.Main Outcome Measures: Cancer (n = 385; 139 breast cancers, 112 cancers in other AMHR2-expressing tissues, 134 cancers in non-AMHR2-expressing tissues).Results: Overall, baseline age-specific AMH levels were not associated with cancer risk, although in women ≤ 40 years an increased risk was suggested for breast cancer (HRT2:T1 = 2.06, 95%CI = 0.95-4.48; HRT3:T1 = 2.03, 95%CI = 0.91-4.50). Analysis of age-related AMH trajectories suggested that AMH levels were higher at younger ages and declined faster in women who were diagnosed with cancer compared with women who were not, but our results did not provide evidence for actual differences in trajectories.Conclusions: Our results did not provide evidence for an association between age-specific AMH levels and age-related trajectories and risk of cancer. However, effect estimates for breast cancer were in line with risk-increasing effects found in previous studies. [ABSTRACT FROM AUTHOR]

Aims: Early age at menarche has been reported to be associated with increased risks of developing type 2 diabetes (T2D) and coronary heart disease (CHD) in adulthood, but a late menarche has also been found to be associated with an increased risk of CHD. Both T2D and CHD are important risk factors for developing heart failure (HF). We examined the relationship between age at menarche (AAM) and HF incidence in women from the European Prospective Investigation into Cancer and Nutrition - Netherlands (EPIC-NL) cohort study.Methods and Results: The EPIC-NL cohort comprised 28,504 women aged 20-70 years at baseline (1993-1997). Mean age at menarche was 13.3 (standard deviation 1.6) years. During a median follow-up of 15.2 years HF occurred in 631 women. Cox proportional hazard regression models, stratified by cohort and adjusted for potential confounders, were used to investigate the associations between AAM and HF incidence. After confounder adjustment, each year of older age at menarche was associated with a 5% lower risk of HF (hazard ratio 0.95 (95% CI, 0.91-1.00), p-value 0.048). Further adjusting for body mass index (BMI), prevalent CHD, hypertension, or prevalent T2D as potential mediators between early menarche and risk of HF attenuated the associations between AAM and risk of HF to non-significance.Conclusion: Older AAM reduced the risk of HF in this study. BMI, prevalent CHD, hypertension and prevalent T2D seemed to mediate this association. Future research with a longer follow-up should establish whether there is an independent effect of AAM on HF risk. Also, further phenotyping of HF cases is necessary to enable whether the associations differ for the various subtypes of HF. [ABSTRACT FROM AUTHOR]
