Association between maternal and paternal mental illness and risk of injuries in children and adolescents: nationwide register based cohort study in Sweden.

ABSTRACT: OBJECTIVE:To determine the association between parental mental illness and the risk of injuries among offspring. DESIGN:Retrospective cohort study. SETTING:Swedish population based registers. PARTICIPANTS:1?542?000 children born in 1996-2011 linked to 893?334 mothers and 873?935 fathers. EXPOSURES:Maternal or paternal mental illness (non-affective psychosis, affective psychosis, alcohol or drug misuse, mood disorders, anxiety and stress related disorders, eating disorders, personality disorders) identified through linkage to inpatient or outpatient healthcare registers. MAIN OUTCOME MEASURES:Risk of injuries (transport injury, fall, burn, drowning and suffocation, poisoning, violence) at ages 0-1, 2-5, 6-9, 10-12, and 13-17 years, comparing children of parents with mental illness and children of parents without mental illness, calculated as the rate difference and rate ratio adjusted for confounders. RESULTS:Children with parental mental illness contributed to 201?670.5 person years of follow-up, while children without parental mental illness contributed to 2?434?161.5 person years. Children of parents with mental illness had higher rates of injuries than children of parents without mental illness (for any injury at age 0-1, these children had an additional 2088 injuries per 100?000 person years; number of injuries for children with and without parental mental illness was 10?235 and 72?723, respectively). At age 0-1, the rate differences ranged from 18 additional transport injuries to 1716 additional fall injuries per 100?000 person years among children with parental mental illness compared with children without parental mental illness. A higher adjusted rate ratio for injuries was observed from birth through adolescence and the risk was highest during the first year of life (adjusted rate ratio at age 0-1 for the overall association between any parental mental illness that has been recorded in the registers and injuries 1.30, 95% confidence interval 1.26 to 1.33). Adjusted rate ratios at age 0-1 ranged from 1.28 (1.24 to 1.32) for fall injuries to 3.54 (2.28 to 5.48) for violence related injuries. Common and serious maternal and paternal mental illness was associated with increased risk of injuries in children, and estimates were slightly higher for common mental disorders. CONCLUSIONS:Parental mental illness is associated with increased risk of injuries among offspring, particularly during the first years of the child's life. Efforts to increase access to parental support for parents with mental illness, and to recognise and treat perinatal mental morbidity in parents in secondary care might prevent child injury.

Project description:BACKGROUND:Anxiety and depression are more common in children with obesity than in children of normal weight, but it is unclear whether this association is independent of other known risk factors. Interpretation of results from previous studies is hampered by methodological limitations, including self-reported assessment of anxiety, depression, and anthropometry. The aim of this study was to investigate whether obesity increases the risk of anxiety or depression independently of other risk factors in a large cohort of children and adolescents, using robust measures with regard to exposure and outcome. METHODS:Children aged 6-17 years in the Swedish Childhood Obesity Treatment Register (BORIS, 2005-2015) were included (n = 12,507) and compared with a matched group (sex, year of birth, and area of residence) from the general population (n = 60,063). The main outcome was a diagnosis of anxiety or depression identified through ICD codes or dispensed prescribed medication within 3 years after the end of obesity treatment. Hazard ratios (HRs) with 95% confidence intervals (CIs) from Cox proportional models were adjusted for several known confounders. RESULTS:Obesity remained a significant risk factor for anxiety and depression in children and adolescents after adjusting for Nordic background, neuropsychiatric disorders, family history of anxiety/depression, and socioeconomic status. Girls in the obesity cohort had a 43% higher risk of anxiety and depression compared to girls in the general population (adjusted HR 1.43, 95% CI 1.31-1.57; p < 0.0001). The risk in boys with obesity was similar (adjusted HR 1.33, 95% CI 1.20-1.48; p < 0.0001). In sensitivity analyses, excluding subjects with neuropsychiatric disorders and a family history of anxiety/depression, the estimated risks in individuals with obesity were even higher compared with results from the main analyses (adjusted HR [95% CI]: girls = 1.56 [1.31-1.87], boys = 2.04 [1.64-2.54]). CONCLUSIONS:Results from this study support the hypothesis that obesity per se is associated with risk of both anxiety and depression in children and adolescents.

Project description:IntroductionRecently, prescribing antipsychotics for children and adolescents has been increasing in many countries. These drugs are often prescribed off-label, although antipsychotics have been associated with adverse effects. We determined the recent incidence of antipsychotic use among children and adolescents in Finland.MethodsFinnish National Prescription Register including all Finnish inhabitants receiving reimbursement for pharmaceuticals was searched for subjects of 1 to 17 years of age who had started an antipsychotic drug between January 1, 2008, and December 31, 2017 (n = 26,353). Between 2008 and 2017, the range of number of Finnish children and adolescents aged 1 to 17 years was 1.01 to 1.03 million/year. The incidence was calculated by dividing the number of new users by all age- and sex-matched Finnish inhabitants in the year.ResultsBetween 2008 and 2017, the incidence of antipsychotic use among children and adolescents increased from 2.1 to 3.8 per 1000 individuals, respectively. In children aged 7 to 12 years, the incidence of antipsychotic use 1.4-folded (from 1.9 (95% CI: 1.8-2.0) to 2.7 (95% CI: 2.5-2.9) per 1000) with a cumulative increase of 0.2% per year (χ2 = 51.0, p < 0.0001). In adolescents aged 13 to 17 years, the incidence 2.2-folded (from 4.3 (95% CI: 4.1-4.5) to 9.4 (95% CI: 9.1-9.8) per 1000) with a cumulative increase of 0.6% per year (χ2 = 590.3, p < 0.0001). The increase in the incidence of use was steeper in girls (2.3-fold) than in boys (1.4-fold) (χ2 = 85.6, p < 0.0001), especially between 2015 and 2017 (1.6-fold and 1.2-fold, respectively) (χ2 = 151.7, p < 0.0001). The year 2011 was the turning point when the incidence in girls exceeded the incidence in boys, and the incidence of quetiapine use exceeded that of risperidone use.ConclusionsThe incidence of antipsychotic use increased between 2008 and 2017, especially in adolescent girls. The use of quetiapine increased, although it has few official indications in children and adolescents. Future studies should investigate the reasons for increasing use of antipsychotics, especially quetiapine, in children and adolescents.

Project description:BackgroundLittle information exists about the prevalence of children exposed to maternal mental illness. We aimed to estimate the prevalence of children and adolescents exposed to maternal mental illness in the UK between 2005 and 2017 using primary care data.MethodsIn this national retrospective cohort study, we included children aged 0-16 years born between Jan 1, 1991, and Dec 31, 2015, who were linked to their mothers and registered on the primary care Clinical Practice Research Datalink (CPRD) between 2005 and 2017. We extracted data on diagnosis, symptoms, and therapy from the CRPD to define the following maternal mental illnesses: depression, anxiety, non-affective psychosis, affective psychosis, eating disorders, personality disorders, alcohol misuse disorder, and substance misuse disorder. We also extracted data on socioeconomic status from the Index of Multiple Deprivation 2010 and data on ethnicity from the Hospital Episode Statistics dataset. The main outcome was prevalence of maternal mental illness. Prevalence was calculated for each 2-year period of childhood (from age 0-<2 to 14-<16 years) using marginal predictions from a logistic regression model. We used survival analysis to estimate the incidence and cumulative risk of children experiencing maternal mental illness by age 16 years.FindingsWe identified 783 710 children registered in the UK CPRD mother-baby link database, and included 547 747 children (381 685 mothers) in our analysis. Overall prevalence of maternal mental illness was 23·2% (95% CI 23·1-23·4), which increased during childhood (21·9%, 21·7-22·1 among the 0-<2 year age group vs 27·3%, 26·8-27·8 among the 14-<16 year age group). Depression and anxiety were the most prevalent maternal mental illnesses. The proportion of children exposed to maternal mental illness increased from 22·2% (21·9-22·4) between 2005 and 2007 to 25·1% (24·8-25·5) between 2015 and 2017. Geographically, the highest prevalence of maternal mental illness was observed in Northern Ireland (29·8%, 29·0-30·5). In England, prevalence of maternal mental illness was highest among children in the most deprived areas (28·3%, 27·8-28·8). The incidence of maternal mental illness was highest between 0-3 months (26·7 per 100 person years, 26·4-27·1). By age 16 years, the cumulative risk of maternal mental illness was 53·1% (52·8-53·3).InterpretationOne in four children aged 0-16 years are exposed to maternal mental illness and the prevalence of diagnosed and treated maternal mental illness is increasing. Policy makers and commissioners should consider this information and channel resources to target individuals in greatest need.FundingThe European Research Council and the National Institute for Health Research.

Project description:ObjectiveTo examine the association between paternal antidepressant use at conception and offspring preterm birth, malformations, autism spectrum disorder, and intellectual disability.DesignObservational prospective cohort study with regression methods, and negative control comparison.SettingSweden nationwide.Participants170 508 children conceived from 29 July 2005 and born in 2006-07, followed up to 2014 at age 8-9 years. This cohort included 3983 children born to fathers receiving antidepressant treatment during the conception period (that is, from four weeks before conception to four weeks after), a control group of 164 492 children not exposed to paternal antidepressant use, and a negative control comparison group of 2033 children born to fathers who did not use antidepressants during the conception period but began antidepressant treatment later during the pregnancy period (that is, from four weeks after conception to childbirth).Main outcome measureOffspring preterm birth, malformation diagnosed at birth, diagnosis of autism spectrum disorder, and diagnosis of intellectual disability.ResultsPaternal antidepressant use during conception was not associated with preterm birth (adjusted odds ratio 0.91 (95% confidence interval 0.79 to 1.04)) or malformations (1.06 (0.90 to 1.26)) using logistic regression, compared with offspring born to unexposed fathers. No association was seen between antidepressant use during conception and autism (adjusted hazard ratio 1.13 (0.84 to 1.53)) or intellectual disability (0.82 (0.51 to 1.31)) using Cox regression. In children whose fathers initiated antidepressant treatment during pregnancy, results were similar for all outcomes apart from intellectual disability, which had an increased adjusted hazard ratio (1.66 (1.06 to 2.59)). Compared with the 2033 children whose fathers initiated antidepressant treatment during pregnancy, the 3983 children exposed to paternal use of antidepressants at conception had no differences in preterm birth, malformation, and autism, but a reduced risk of intellectual disability (adjusted hazard ratio 0.49 (0.26 to 0.93)).ConclusionPaternal intake of antidepressants during the period around conception is safe with respect to the risk of the four major adverse outcomes in offspring-preterm birth, malformation, autism, or intellectual disability.
