Maternal depression and childhood injury risk: A population-based cohort study in Denmark.
Ontology highlight
ABSTRACT: Aims
To assess the association between different stages of maternal depression and injury risk in offspring aged 0-10 years.Methods
Population-based cohort study of all live-born children in Denmark from 1 January 1997 until 31 December 2013 (n = 1,064,387). Main outcome measure was emergency department contacts with a main diagnosis of injury coded as DS00-DT98 (chapter XIX) according to the ICD-10. All information was obtained from Danish national registries.Results
Maternal depression was associated with higher injury hazard in the offspring throughout childhood compared to offspring of mothers with no history of depression. The strongest association was seen for the first year of life. First-time maternal depression was most strongly associated with injury in the child, especially in the first year of life (aHR = 1.70, 95% CI: 1.48-1.96). Children of mothers with relapse depression had 1.57 higher hazard of injury in the first year of life (aHR: 1.57, 95% CI: 1.44-1.70). Children of mothers with previously treated depression (postdepression) had 1.13 higher hazard of injury in the first year of life (aHR: 1.13, 95% CI: 1.09-1.17). Continuous treatment for depression was associated with a nonsignificant higher hazard of injuries in the first year of life (aHR: 1.06, 95% CI: 0.91-1.23).Conclusions
Maternal depression was associated with higher injury risk in the offspring, particularly in early childhood. The association persisted in children of mothers with relapse depression. Our results suggest that children of mothers with depression are vulnerable several years after depression onset and treatment cessation.

Project description:To estimate risks of major congenital anomaly (MCA) among children of mothers prescribed antidepressants during early pregnancy or diagnosed with depression but without antidepressant prescriptions.Population-based cohort study.Linked UK maternal-child primary care records.A total of 349,127 singletons liveborn between 1990 and 2009.Odds ratios adjusted for maternal sociodemographics and comorbidities (aORs) were calculated for MCAs, comparing women with first-trimester selective serotonin reuptake inhibitors (SSRIs) or tricyclic antidepressants (TCAs) and women with diagnosed but unmedicated depression, or women without diagnosed depression.Fourteen system-specific MCA groups classified according to the European Surveillance of Congenital Anomalies and five specific heart anomaly groups.Absolute risks of MCA were 2.7% (95% confidence interval, 95% CI, 2.6-2.8%) in children of mothers without diagnosed depression, 2.8% (95% CI 2.5-3.2%) in children of mothers with unmedicated depression, and 2.7% (95% CI 2.2-3.2%) and 3.1% (95% CI 2.2-4.1%) in children of mothers with SSRIs or TCAs, respectively. Compared with women without depression, MCA overall was not associated with unmedicated depression (aOR 1.07, 95% CI 0.96-1.18), SSRIs (aOR 1.01, 95% CI 0.88-1.17), or TCAs (aOR 1.09, 95% CI 0.87-1.38). Paroxetine was associated with increased heart anomalies (absolute risk 1.4% in the exposed group compared with 0.8% in women without depression; aOR 1.78, 95% CI 1.09-2.88), which decreased marginally when compared with women with diagnosed but unmedicated depression (aOR 1.67, 95% CI 1.00-2.80).Overall MCA risk did not increase with maternal depression or with antidepressant prescriptions. Paroxetine was associated with increases of heart anomalies, although this could represent a chance finding from a large number of comparisons undertaken.

Project description:Depression and anxiety disorders are highly comorbid conditions and a worldwide disease burden; however, large-scale studies delineating their association are scarce. In this retrospective study, we aimed to assess the effect of severe anxiety disorders on the risk and course of depression.We did a population-based cohort study with prospectively gathered data in Denmark using data from three Danish population registers: The Danish Civil Registration System, the Danish Psychiatric Central Register, and the Danish National Hospital Registry. We selected the cohort from people born in Denmark between Jan 1, 1955, and Dec 31, 2002, who we followed up from Jan 1, 1994, to Dec 31, 2012. The cohort was restricted to individuals with known parents. First, we investigated the effect of specific anxiety diagnoses on risk of single depressive episodes and recurrent depressive disorder. Second, we investigated the effect of comorbid anxiety on risk of readmission for depression, adjusting for sex, age, calendar year, parental age, place at residence at time of birth, and the interaction of age with sex.We included 3,380,059 individuals in our study cohort. The adjusted incidence rate ratio (IRR) for single depressive episodes was 3·0 (95% CI 2·8-3·1, p<0·0001) and for recurrent depressive disorder was 5·0 (4·8-5·2) in patients with severe anxiety disorders compared with the general population. Compared with control individuals, the offspring of parents with anxiety disorders were more likely to be diagnosed with single depressive episodes (1·9, 1·8-2·0) or recurrent depressive disorder (2·1, 1·9-2·2). Comorbid anxiety increased the readmission rates in both patients with single depressive episodes and patients with recurrent depressive disorder.Severe anxiety constitutes a significant risk factor for depression. Focusing on specific anxiety disorders might help to identify individuals at risk of depression, thereby providing new insights for prevention and treatment.The Lundbeck Foundation Initiative for Integrative Psychiatric Research (iPSYCH).

Project description:BackgroundAdverse childhood life events are associated with increased risks of hypertension, ischemic heart disease, and stroke later in life. Limited evidence also suggests that stress in adulthood may increase the risk of atrial fibrillation (AF). Whether childhood adversity may lead to the development of AF is unknown. We investigated whether the loss of a parent or sibling in childhood is associated with an increased risk of AF and compared this effect to that of similar losses in young adulthood.MethodsWe studied 6,394,975 live-born individuals included in the Danish (1973-2018) and Swedish Medical Birth Registers (1973-2014). We linked data from several national registers to obtain information on the death of parents and siblings and on personal and familial sociodemographic and health-related factors. We analyzed the association between bereavement and AF using Poisson regression.ResultsLoss of a parent or sibling was associated with an increased AF risk both when the loss occurred in childhood and in adulthood; the adjusted incident rate ratios and 95% confidence intervals were 1.24 (1.14-1.35) and 1.24 (1.16-1.33), respectively. Bereavement in childhood was associated with AF only if losses were due to cardiovascular diseases or other natural causes, while loss in adulthood was associated with AF not only in case of natural deaths, but also unnatural deaths. The associations did not differ substantially according to age at loss and whether the deceased was a parent or a sibling.ConclusionsBereavement both in childhood and in adulthood was associated with an increased AF risk.

Project description:BackgroundMaternal infection during pregnancy may be a risk factor for epilepsy in offspring. Use of antibiotics is a valid marker of infection.Methodology/principal findingsTo examine the relationship between maternal infection during pregnancy and risk of childhood epilepsy we conducted a historical cohort study of singletons born in northern Denmark from 1998 through 2008 who survived ≥29 days. We used population-based medical databases to ascertain maternal use of antibiotics or hospital contacts with infection during pregnancy, as well as first-time hospital contacts with a diagnosis of epilepsy among offspring. We compared incidence rates (IR) of epilepsy among children of mothers with and without infection during pregnancy. We examined the outcome according to trimester of exposure, type of antibiotic, and total number of prescriptions, using Poisson regression to estimate incidence rate ratios (IRRs) while adjusting for covariates. Among 191,383 children in the cohort, 948 (0.5%) were hospitalised or had an outpatient visit for epilepsy during follow-up, yielding an IR of 91 per 100 000 person-years (PY). The five-year cumulative incidence of epilepsy was 4.5 per 1000 children. Among children exposed prenatally to maternal infection, the IR was 117 per 100,000 PY, with an adjusted IRR of 1.40 (95% confidence interval (CI): 1.22-1.61), compared with unexposed children. The association was unaffected by trimester of exposure, antibiotic type, or prescription count.Conclusions/significancePrenatal exposure to maternal infection is associated with an increased risk of epilepsy in childhood. The similarity of estimates across types of antibiotics suggests that processes common to all infections underlie this outcome, rather than specific pathogens or drugs.

Project description:Few studies have explored predictors of early childhood anxiety.To determine the prenatal, postnatal, and early life predictors of childhood anxiety by age 5.Population-based, provincial administrative data (N = 19,316) from Manitoba, Canada were used to determine the association between demographic, obstetrical, psychosocial, medical, behavioral, and infant factors on childhood anxiety.Risk factors for childhood anxiety by age 5 included maternal psychological distress from birth to 12 months and 13 months to 5 years post-delivery and an infant 5-minute Apgar score of ≤7. Factors associated with decreased risk included maternal age < 20 years, multiparity, and preterm birth.Identifying predictors of childhood anxiety is a key step to early detection and prevention. Maternal psychological distress is an early, modifiable risk factor. Future research should aim to disentangle early life influences on childhood anxiety occurring in the prenatal, postnatal, and early childhood periods.

Project description:BackgroundThe time interval from first symptom and sign until a cancer diagnosis significantly affects the prognosis. Therefore, recognising and acting on signs of cancer, such as anaemia, is essential. Evidence is sparse on the overall risk of cancer and the risk of specific cancer types in persons with new-onset anaemia detected in an unselected general practice population. We aimed to assess the risk of cancer in persons with new-onset anaemia detected in general practice, both overall and for selected cancer types.MethodsThis observational population-based cohort study used individually linked electronic data from laboratory information systems and nationwide healthcare registries in Denmark. We included persons aged 40-90 years without a prior history of cancer and with new-onset anaemia (no anaemia during the previous 15 months) detected in general practice in 2014-2018. We measured the incidence proportion and standardised incidence ratios of a new cancer diagnosis (all cancers except for non-melanoma skin cancers) during 12 months follow-up.ResultsA total of 48,925 persons (median [interquartile interval] age, 69 [55-78] years; 55.5% men) were included in the study. In total, 7.9% (95% confidence interval (CI): 7.6 to 8.2) of men and 5.2% (CI: 4.9 to 5.5) of women were diagnosed with cancer during 12 months. Across selected anaemia types, the highest cancer incidence proportion was seen in women with 'anaemia of inflammation' (15.3%, CI: 13.1 to 17.5) (ferritin > 100 ng/mL and increased C-reactive protein (CRP)) and in men with 'combined inflammatory iron deficiency anaemia' (19.3%, CI: 14.5 to 24.1) (ferritin < 100 ng/mL and increased CRP). For these two anaemia types, the cancer incidence across cancer types was 10- to 30-fold higher compared to the general population.ConclusionsPersons with new-onset anaemia detected in general practice have a high cancer risk; and markedly high for 'combined inflammatory iron deficiency anaemia' and 'anaemia of inflammation'. Anaemia is a sign of cancer that calls for increased awareness and action. There is a need for research on how to improve the initial pathway for new-onset anaemia in general practice.

Project description:ObjectiveAsthma is a common chronic disease that imposes a substantial burden on individuals and society. However, the natural history of childhood asthma in a large population remained to be studied. This study aimed to describe the natural course of childhood asthma and examine the association between early life factors and childhood asthma.DesignA population-based cohort study.SettingThis study was based on the national registry data in Denmark.ParticipantsAll liveborn singletons in Denmark during 1995-1997 were identified and followed them till the end of 2009. Finally, 193 673 children were eligible for our study.ExposuresThe following characteristics were examined as potential early life factors associated with childhood asthma, including parity, maternal asthma history, maternal smoking during pregnancy, maternal social status, delivery method and gender.Main outcomes and measuresAsthma cases were identified on the basis of hospitalisation for asthma and prescriptions for antiasthmatic medications. Asthma remission was defined as no hospitalisation or prescription recorded for 2 years. Cox proportional hazards' regression and logistic regression were used to evaluate the association between early life factors and the occurrence and remission of childhood asthma.ResultsThe cumulative occurrence rate of asthma in children aged 3-14 years was 13.3% and the remission rate was 44.1%. The occurrence rate decreased with age. Being female had a lower risk of asthma (HR: 0.72, 95% CI 0.70 to 0.74) and higher remission rate of asthma (HR: 1.18, 1.13 to 1.22), while maternal asthma was associated with a higher risk of asthma (HR: 2.15, 2.04 to 2.26) and decreased remission rate of asthma (HR: 0.79, 0.73 to 0.85). These patterns remained the same for early onset asthma.ConclusionsFemale gender had a lower risk of asthma and a better chance of remission, while maternal asthma history had an opposite effect. The early life factors may influence the natural course of childhood asthma.

Project description:ObjectiveTo use data from two longstanding, population based screening programmes to study overdiagnosis in screening mammography.DesignPopulation based cohort study.SettingCopenhagen municipality (from 1991) and Funen County (from 1993), Denmark.Participants57,763 women targeted by organised screening, aged 56-69 when the screening programmes started, and followed up to 2009.Main outcome measuresOverdiagnosis of breast cancer in women targeted by screening, assessed by relative risks compared with historical control groups from screening regions, national control groups from non-screening regions, and historical national control groups.ResultsIn total, 3279 invasive breast carcinomas and ductal carcinomas in situ occurred. The start of screening led to prevalence peaks in breast cancer incidence: relative risk 2.06 (95% confidence interval 1.64 to 2.59) for Copenhagen and 1.84 (1.46 to 2.32) for Funen. During subsequent screening rounds, relative risks were slightly above unity: 1.04 (0.85 to 1.27) for Copenhagen and 1.14 (0.98 to 1.32) for Funen. A compensatory dip was seen after the end of invitation to screening: relative risk 0.80 (0.65 to 0.98) for Copenhagen and 0.67 (0.55 to 0.81) for Funen during the first four years. The relative risk of breast cancer accumulated over the entire follow-up period was 1.06 (0.90 to 1.25) for Copenhagen and 1.01 (0.93 to 1.10) for Funen. Relative risks for participants corrected for selection bias were estimated to be 1.08 for Copenhagen and 1.02 for Funen; for participants followed for at least eight years after the end of screening, they were 1.05 and 1.01. A pooled estimate gave 1.040 (0.99 to 1.09) for all targeted women and 1.023 (0.97 to 1.08) for targeted women followed for at least eight years after the end of screening.ConclusionsOn the basis of combined data from the two screening programmes, this study indicated that overdiagnosis most likely amounted to 2.3% (95% confidence interval -3% to 8%) in targeted women. Among participants, it was most likely 1-5%. At least eight years after the end of screening were needed to compensate for the excess incidence during screening.

Project description:To examine whether abnormal prenatal biochemical screening results are associated with an increased risk of premature cardiovascular disease after pregnancy.Population based cohort study.The entire province of Ontario, Canada, where healthcare is universally available.Women aged 12-55 years, without pre-existing cardiovascular disease, who underwent prenatal screening between 1993 and 2011. One pregnancy per woman was randomly selected.Low (?5th centile multiple of the median) serum total chorionic gonadotropin, unconjugated estriol, and pregnancy associated plasma protein A and high (?95th centile multiple of the median) alphafetoprotein and dimeric inhibin-A.Composite of hospital admission or revascularisation for coronary artery, cerebrovascular, or peripheral arterial disease or hospital admission for heart failure or dysrhythmia at least 365 days after pregnancy.Among 855?536 pregnancies, and after a median of 11.4 (interquartile range 6.8-17.5) years of follow-up, 6209 women developed the main cardiovascular disease outcome. Abnormal results for each of the five prenatal biochemical screening analytes, especially dimeric inhibin-A, were associated with a higher risk of cardiovascular disease. Women with an abnormally high dimeric inhibin-A (?95th centile) had the highest rate of cardiovascular disease (30 events or 8.3 per 10?000 person years versus 251 events or 3.8 per 10?000 person years for those <95th centile; multivariable adjusted hazard ratio 2.0, 95% confidence interval 1.4 to 3.0). Compared with women without any abnormal biochemical measure, the hazard ratio for the cardiovascular disease composite outcome was 1.2-1.3 times higher with one abnormal analyte and 1.5-2.0 times higher with two or more abnormal analytes.Women with abnormal prenatal biochemical screening results, especially for dimeric inhibin-A, may be at higher risk of cardiovascular disease. If these findings are replicated elsewhere, a massive amount of data exists that could aid in identifying women at higher risk of premature cardiovascular disease and that could be conveyed to them or their healthcare providers.

Project description:ObjectiveIn a large population-based cohort in Denmark to examine if maternal use of antibiotics during pregnancy, as a marker of infection, increases the risk of febrile seizures in childhood in a large population-based cohort in Denmark.MethodsAll live-born singletons born in Denmark between January 1, 1996 and September 25, 2004 and who were alive on the 90(th) day of life were identified from the Danish National Birth Registry. Diagnoses of febrile seizures were obtained from the Danish National Hospital Register and maternal use of antibiotics was obtained from the National Register of Medicinal Product Statistics. Hazard ratios (HR) and 95% confidence intervals (95% CI) were estimated by Cox proportional hazard regression models.ResultsWe followed 551,518 singletons for up to 5 years and identified a total of 21,779 children with a diagnosis of febrile seizures. Slightly increased hazard ratios were observed among most exposure groups when compared to the unexposed group, ex. HR 1.08 95% CI: 1.05-1.11 for use of any systemic antibiotic during pregnancy.ConclusionWe found weak associations between the use of pharmacologically different antibiotics during pregnancy and febrile seizures in early childhood which may indicate that some infections, or causes or effects of infections, during pregnancy could affect the fetal brain and induce susceptibility to febrile seizures.
