Child maltreatment: variation in trends and policies in six developed countries

We explored trends in six developed countries in three types of indicators of child maltreatment for children younger than 11 years, since the inception of modern child protection systems in the 1970s. Despite several policy initiatives for child protection, we recorded no consistent evidence for a decrease in all types of indicators of child maltreatment. We noted falling rates of violent death in a few age and country groups, but these decreases coincided with reductions in admissions to hospital for maltreatment-related injury only in Sweden and Manitoba (Canada). One or more child protection agency indicators increased in five of six countries, particularly in infants, possibly as a result of early intervention policies. Comparisons of mean rates between countries showed five-fold to ten-fold differences in rates of agency indicators, but less than two-fold variation in violent deaths or maltreatment-related injury, apart from high rates of violent child death in the USA. These analyses draw attention to the need for robust research to establish whether the high and rising rates of agency contacts and out-of-home care in some settings are effectively reducing child maltreatment.

Child abuse and neglect--is it time for a public health approach?

Australia is seeing an unprecedented increase in the rate of child protection notifications and children being taken into care. The burden of such high levels of notifications and removals impact not only the children and families but also the system which is trying to resource them. The concern is that these increases are unsustainable and overloaded child protection systems can be dangerous for the vulnerable families and children they are trying to protect and support.

Increasing Prevalence of Neonatal Withdrawal Syndrome: Population Study of Maternal Factors and Child Protection Involvement

OBJECTIVES. Illicit drug use during pregnancy is an important public health issue, with adverse effects on the newborn and implications for subsequent parenting. The aim of this study was to measure the birth prevalence of neonatal withdrawal syndrome over time, associated maternal characteristics and child protection involvement. METHODS. This is a retrospective cohort study that used linked health and child protection databases for all live births in Western Australia from 1980 to 2005. Maternal characteristics and mental health–and assault-related medical history were assessed by using logistic regression models. RESULTS. The birth prevalence of neonatal withdrawal syndrome increased from 0.97 to a high of 42.2 per 10 000 live births, plateauing after 2002. Mothers with a previous mental health admission, low skill level, Aboriginal status or who smoked during pregnancy were significantly more likely to have an infant with neonatal withdrawal syndrome. These infants were at greater risk for having a substantiated child maltreatment allegation and entering foster care. Increased risk for maltreatment was associated with mothers who were aged <30 years, were from socially disadvantaged backgrounds, Aboriginal status, and had a mental health–or assault-related admission. CONCLUSIONS. There has been a marked increase in neonatal withdrawal syndrome in the past 25 years. Specific maternal characteristics identified should facilitate planning for early identification and intervention for these women. Findings demonstrate an important pathway into child maltreatment and highlight the need for well-supported programs for women who use illicit drugs during pregnancy as well as the need for sustained long-term support after birth.

Characteristics of non-Aboriginal and Aboriginal children and families with substantiated child maltreatment: a population-based study

OBJECTIVES To investigate specific child and parental factors associated with increased vulnerability to substantiated child maltreatment. METHODS A retrospective cohort study of all children born in Western Australia during 1990-2005 using de-identified record linked child protection, disability services and health data. Cox regression was used for univariate and multivariate analysis to determine the risk of substantiated child maltreatment for a number of child and parental factors, including child disability, parental age, socio-economic status, parental mental health, substance use and assault-related hospital admissions. Separate analyses were conducted for Aboriginal and non-Aboriginal children. RESULTS This study found a number of child and parental factors that increase the risk of substantiated child maltreatment. The strongest factors were child intellectual disability, parental socio-economic status, parental age and parental hospital admissions related to mental health, substance use and assault. CONCLUSIONS Awareness of the factors that make children and families vulnerable may aid the targeting of child maltreatment prevention programmes. To prevent child abuse and neglect it is essential that we have a platform of universal services, which assist parents in their role, as well as targeted services for at-risk families.

Monitoring child abuse and neglect at a population level: Patterns of hospital admissions for maltreatment and assault

OBJECTIVES To investigate the prevalence, trends, and characteristics of maltreatment and assault related hospital admissions and deaths among children; and identify common injuries and conditions associated with these admissions using routinely collected morbidity and mortality data. METHODS A retrospective cohort study of all children aged 0-17 years in Western Australia from 1980 to 2005 was identified from linked de-identified population level data. Annual trends in prevalence of assault and maltreatment related admissions were calculated and child characteristics were investigated using logistic regression models. RESULTS Assault admissions more than doubled from 2.8 per 10,000 children in 1981 to 6.1 per 10,000 in 2005 (p<0.0001) and maltreatment admissions rose from 0.7 per 10,000 children in 1981 to 1.3 per 10,000 in 2005 (p<0.0001). Males aged greater than 12 years were at greater risk of an assault, while children aged less than 6 years were more likely to be at risk of maltreatment as well as those from greater disadvantaged backgrounds. Aboriginal children were more likely to be identified with assault and maltreatment compared to non-Aboriginal children. Common indicators of assault admissions included injuries of the skull and facial bones, intracranial, wrist, hand, and abdominal injuries. Children with maltreatment-related admissions were more likely to have superficial head or abdominal injuries and a high proportion had infectious and parasitic diseases, particularly intestinal infections. Many of these cases were associated with factors influencing health status, particularly socioeconomic and psychosocial circumstances. CONCLUSIONS There has been a steady increase in the prevalence of assault and maltreatment related admissions. Specific child characteristics and injuries associated with child assault and maltreatment-related admissions have been identified using routinely collected morbidity data and may be utilized as potential indicators for identifying and monitoring child abuse and neglect. PRACTICE IMPLICATIONS Broadening child maltreatment surveillance to childrens admissions for assault and maltreatment is an important public health initiative which can be improved by the increased use of external cause codes. Health data is collected using international coding standards enhancing comparability across states and countries and has clinical implications in highlighting injuries associated with child abuse and neglect.

Neonatal drug withdrawal syndrome: cross-country comparison using hospital administrative data in England, the USA, Western Australia and Ontario, Canada

Objectives We determined trends over time in the prevalence of neonatal drug withdrawal syndrome (NWS) in England compared with that reported in the USA, Western (W) Australia and Ontario, Canada. We also examined variation in prevalence of NWS according to maternal age, birth weight and across the English NHS by hospital trusts. Design and setting Retrospective study using national hospital administrative data (Hospital Episode Statistics) for the NHS in England between 1997 and 2011. NWS was identified using international classification of disease codes in hospital admission records. We searched the research literature and contacted researchers to identify studies reporting trends in the prevalence of NWS. Main outcome measures Prevalence of NWS by calendar year per 1000 live births for each country/state. For births in England, prevalence by maternal age group and birth weight group. Prevalence by NHS trust and region at birth, and funnel plot to show outlying English NHS hospital trusts (>3 SD of mean prevalence). Main results Mean prevalence rates of recorded NWS increased in all four countries. Rates stabilised in England and W. Australia from the early 2000s and rose steeply in the USA and Ontario during the late 2000s. The most recent prevalence rates were 2.7/1000 live births in England (2011; 1544 cases); 2.7/1000 in W. Australia (2009); 3.6/1000 in the USA (2009) and 5.1/1000 in Ontario (2011). The highest prevalence in England was among babies born to mothers aged 25–34 years at delivery and among babies born with low birth weight (1500–2500 g). In England in 2011, 8.6% of hospital trusts had a recorded prevalence outside 3 SD of the overall average (7% above, 1% below). The North East region of England had the highest recorded prevalence of NWS. Conclusions Although recorded NWS is stable in England and W. Australia, rising rates in the USA and Ontario may reflect better recognition and/or increased use of prescribed opiate analgesics and highlight the need for surveillance. The extent to which different prevalence rates by hospital trust reflect variation in occurrence, recognition or recording requires further investigation.

Rates and types of hospitalisations for children who have subsequent contact with the child protection system: a population based case-control study

Objectives To determine whether children who have child maltreatment allegation or substantiation have a higher rate of general hospital admissions and injury related admissions when compared to other children and to investigate other types of admissions, such as mental health, infections and admissions due to external causes. Study design A prospective matched case-control study of children born in Western Australia between 1990 and 2005 using de-identified record linked Child Protection and Hospital Morbidity data. Rates of prior hospital admissions for cases versus controls were calculated, and conditional logistic regression was used to estimate the effect of hospital admission rate on the risk of child maltreatment allegation and substantiated allegation. Results Children with child maltreatment allegations and substantiations had higher mean prior admission rates compared to controls. Higher rates of general admissions and admissions for injuries, infections, mental and behavioural disorders, and external causes of morbidity, were associated with a markedly increased risk of child maltreatment allegations and substantiation. Conclusions The hospital system plays not only an important role both in the surveillance of maltreatment-related injuries and conditions but also in the role of prevention in the referral of families who may need support and assistance in ensuring the health and safety of their children. This research highlights the importance of moving to electronic patient records in identifying children who have high rates of admissions and the types of conditions they have previously presented with, particularly for injuries, mental and behavioural disorders and external causes of admissions.

Western Australian emergency department presentations related to child maltreatment and intentional injury: Population level study utilising linked health and child protection data

Aim:  The aim of this study is to determine the proportion of child maltreatment‐related emergency department (ED) presentations in Western Australia (WA) and describe the type of injuries associated with them. It is also to investigate the proportion of maltreatment‐related ED presentations resulting in hospitalisation, the proportion referred to the Department for Child Protection and their outcomes.

Maternal mental health and risk of child protection involvement: mental health diagnoses associated with increased risk

Background Previous research shows that maternal mental illness is an important risk factor for child maltreatment. This study aims to quantify the relationship between maternal mental health and risk of child maltreatment according to the different types of mental health diagnoses. Methods The study used a retrospective cohort of children born in Western Australia between 1990 and 2005, with deidentified linked data from routine health and child protection collections. Results Nearly 1 in 10 children (9.2%) of mothers with a prior mental health contact had a maltreatment allegation. Alternatively, almost half the children with a maltreatment allegation had a mother with a mental health contact. After adjusting for other risk factors, a history of mental health contacts was associated with a more than doubled risk of allegations (HR=2.64, 95% CI 2.50 to 2.80). Overall, all mental health diagnostic groups were associated with an increased risk of allegations. The greatest risk was found for maternal intellectual disability, followed by disorders of childhood and psychological development, personality disorders, substance-related disorders, and organic disorders. Maltreatment allegations were substantiated at a slightly higher rate than for the general population. Conclusions Our study shows that maternal mental health is an important factor in child protection involvement. The level of risk varies across diagnostic groups. It is important that mothers with mental health issues are offered appropriate support and services. Adult mental health services should also be aware and discuss the impact of maternal mental health on the family and childrens safety and well-being.
