Suicide and suicide attempts in children and adolescents in the child welfare system

Background: Few population studies have examined the psychiatric outcomes of children and adolescents in the child welfare system, and no studies have compared outcomes before and after entry into care. Our objective was to assess the relative rate (RR) of suicide, attempted suicide, admission to hospital and visits to physicians’ offices among children and adolescents in care compared with those not in care. We also examined these outcomes within the child welfare population before and after entry into care. Methods: We used population-level data to identify children and adolescents 5 to 17 years of age who were in care in Manitoba for the first time between Apr. 1, 1997, and Mar. 31, 2006, and a comparison cohort not in care. We compared the two cohorts to obtain RRs for the specified outcomes. We also determined RRs within the child welfare population relative to the same population two years before entry into care. Results: We identified 8279 children and adolescents in care for the first time and a comparison cohort of 353 050 children and adolescents not in care. Outcome rates were higher among those in care than in the comparison cohort for suicide (adjusted RR 3.54, 95% confidence interval [CI] 2.11–5.95), attempted suicide (adjusted RR 2.11, 95% CI 1.84–2.43) and all other outcomes. However, adjusted RRs for attempted suicide (RR 0.27, 95% CI 0.21–0.34), admissions to hospital and physician visits decreased after entry into care. Interpretation: Children and adolescents in care were at greater risk of suicide and attempting suicide than those who were not in care. Rates of suicide attempts and hospital admissions within this population were highest before entry into care and decreased thereafter.

Bereavement after sibling death: a population-based longitudinal case-control study

The objective of this study was to examine mental disorders and treatment use among bereaved siblings in the general population. Siblings (N=7243) of all deceased children in the population of Manitoba, Canada who died between 1984 and 2009 were matched 1:3 to control siblings (N=21,729) who did not have a sibling die in the study period. Generalized estimating equations were used to compare the two sibling groups in the two years before and after the index childs death on physician‐diagnosed mental disorders and treatment utilization, with adjustment for confounding factors including pre‐existing mental illness. Analyses were stratified by age of the bereaved (<13 vs. 13+). Results revealed that, in the two years after the death of the child, bereaved siblings had significantly higher rates of mental disorders than control siblings, even after adjusting for pre‐existing mental illness. When comparing the effect of a childs death on younger versus older siblings, the rise in depression rates from pre‐death to post‐death was significantly higher for siblings aged under 13 (p<0.0001), increasing more than 7‐fold (adjusted relative rate, ARR=7.25, 95% CI: 3.65‐14.43). Bereaved siblings aged 13+ had substantial morbidity in the two years after the death: 25% were diagnosed with a mental disorder (vs. 17% of controls), and they had higher rates of almost all mental disorder outcomes compared to controls, including twice the rate of suicide attempts (ARR=2.01, 95% CI: 1.29‐3.12). Siblings in the bereaved cohort had higher rates of alcohol and drug use disorders already before the death of their sibling. In conclusion, the death of a child is associated with considerable mental disorder burden among surviving siblings. Pre‐existing health problems and social disadvantage do not fully account for the increase in mental disorder rates.

Parental Bereavement After the Death of an Offspring in a Motor Vehicle Collision: A Population-based Study

Motor vehicle collisions (MVCs) are the leading cause of death in young people in North America. The effects of such deaths on parents have not been systematically studied. Administrative data sets were used to identify all parents (n = 1,458) who had an offspring die in a MVC between 1996 and 2008 in the province of Manitoba, Canada. They were matched to general population control parents who had not had offspring die from any sudden cause during the study period. Generalized estimating equations were used to compare the rates of physician-diagnosed mental and physical disorders, social factors, and treatment utilization in the 2 parent groups in the 2 years before and after offspring death, with adjustment for confounding factors. The risk of depression among bereaved parents almost tripled (adjusted prevalence ratio = 2.85, 95% confidence interval: 2.44, 3.33; P < 0.001) during the 2 years after death of an offspring. Significant increases in the risk of anxiety disorders (adjusted prevalence ratio = 1.45, 95% confidence interval: 1.26, 1.67; P < 0.001) were also observed. When compared with nonbereaved parents, bereaved parents had significant increases in the risks of depression (P < 0.001), anxiety disorders (P < 0.001), marital break-up (P = 0.015), and physician visits for mental illness (P < 0.001) in the post-death period. In conclusion, parents who lose an offspring in a MVC experience considerable mental illness and marital disruption.

Evaluation of a Newborn Screen for Predicting Out-of-Home Placement

A newborn screen designed to predict family risk was examined to: (a) determine whether all families with newborns were screened; (b) evaluate its predictive validity for identifying risk of out-of-home placement, as a proxy for maltreatment; (c) determine which items were most predictive of out-of-home placement. All infants born in Manitoba, Canada from 2000 to 2002 were followed until March 31, 2004 (N = 40,886) by linking four population-based data sets: (a) newborn screening data on biological, psychological, and social risks; (b) population registry data on demographics; (c) hospital discharge data on newborn birth records; (d) data on children entering out-of-home care. Of the study population, 18.4% were not screened and 3.0% were placed in out-of-home care at least once during the study period. Infants not screened were twice as likely to enter care compared to those screened (4.9% vs. 2.5%). Infants screening at risk were 15 times more likely to enter care than those screening “not at risk.” Sensitivity and specificity of the screen were 77.6% and 83.3%, respectively. Screening efforts to identify vulnerable families missed a substantial portion of families needing support. The screening tool demonstrated moderate predictive validity for identifying children at risk of entering care in the first years of life.

Program for Expectant and New Mothers: A Population-Based Study of Participation

BackgroundThe Manitoba Healthy Baby Program is aimed at promoting pre- and perinatal health and includes two components: 1) prenatal income supplement; 2) community support programs. The goal of this research was to determine the uptake of these components by target groups.MethodsData on participation in each of the two program components were linked to data on all hospital births in Manitoba between 2004/05 through 2007/08. Descriptive analyses of participation by maternal characteristics were produced. Logistic regression analyses were conducted to identify factors associated with participation in the two programs. Separate regressions were run for two groups of women giving birth during the study period: 1) total population; 2) those receiving provincial income assistance during the prenatal period.ResultsAlmost 30% of women giving birth in Manitoba received the Healthy Baby prenatal income supplement, whereas only 12.6% participated in any community support programs. Over one quarter (26.4%) of pregnant women on income assistance did not apply for and receive the prenatal income supplement, despite all being eligible for it. Furthermore, 77.8% of women on income assistance did not participate in community support programs. Factors associated with both receipt of the prenatal benefit and participation in community support programs included lower SES, receipt of income assistance, obtaining adequate prenatal care, having completed high school and having depressive symptoms. Having more previous births was associated with higher odds of receiving the prenatal benefit, but lower odds of attending community support programs. Being married was associated with lower odds of receiving the prenatal benefit but higher odds of participating in community support programs.ConclusionsAlthough uptake of the Healthy Baby program in Manitoba is greater for women in groups at risk for poorer perinatal outcomes, a substantial number of women eligible for this program are not receiving it; efforts to reach these women should be enhanced.
