Objective Assess the association between caregiver supervision and acute unintentional injury in young children; evaluate whether lower levels of supervision result in more severe injury. Methods A case cross-over study was conducted. Parents of children aged ≤4 years whose injuries required emergency department (ED sample) treatment or admission to the hospital (inpatient sample) were interviewed. Information on supervision (3 dimensions: proximity, attention, continuity) at the time of injury and 1 h before the injury (control time) was collected. An overall supervision score was created; a higher score indicates closer supervision. Hospital admission served as a proxy for injury severity. ORs and 95% CIs were calculated. Results Interviews were completed by 222 participants; 50 (23%) were in the inpatient sample. For each supervision dimension the inpatient sample had higher odds of injury, indicating effect modification requiring separate analyses for inpatient and ED samples. For both samples, proximity ‘beyond reach' was associated with the highest odds of injury; compared with 1 h before injury, children were more likely to be beyond reach of their caregiver at the time of injury (inpatient sample: OR 11.5, 95% CI 2.7 to 48.8; ED sample: OR 2.9, 95% CI 1.8 to 4.9). Children with lower supervision scores had the greatest odds of injury (inpatient sample: OR 8.0, 95% CI 2.4 to 26.6; ED sample: OR 3.3, 95% CI 1.9 to 5.6). Conclusions Lower levels of adult supervision are associated with higher odds of more severe injury in young children. Proximity is the most important supervision dimension for reducing injury risk.

OBJECTIVES: Sudden infant death syndrome (SIDS) is a major cause of infant mortality and is associated with the prone sleeping position. Our goal was to determine changes in newborn nursery policies and practices regarding infant sleeping position between 1992 and 1999. STUDY DESIGN: We conducted telephone interviews with the head nurses in all of the newborn nurseries in Missouri. POPULATION: In 1992 there were 79 hospitals in Missouri with newborn nurseries; in 1999 that number had decreased to 75. OUTCOMES MEASURED: During the interviews, we solicited nursery infant sleep position policy and practice, head nurses' opinions about the supine sleep recommendation, and nurses' advice to parents regarding sleep position. RESULTS: In 1992, 32% of the nurseries used the prone position for sleep, and 58% of the head nurses interviewed disagreed with the recommendations of the American Academy of Pediatrics (AAP). By 1999, all newborn nurseries in Missouri placed infants on their backs or sides for sleep. The rate of disagreement with the AAP recommendation had decreased, with 25% of respondents indicating that they disagreed. CONCLUSIONS: From 1992 to 1999 nurseries in Missouri have changed from predominantly using prone and lateral positioning to lateral and supine positioning for newborns. Some nurses continue to voice concern about placing infants on their backs and expressed a willingness to place babies prone. Since there is agreement between nurses' usual infant positioning and the advice given to parents, and because both are important influences on infant positioning by parents, future campaigns to decrease SIDS should emphasize correcting nurses' positioning behavior and advising parents to increase infant supine positioning.

Objective: To determine whether there is seasonal variation (by season and month of year) in homicides among young children., Study Design: Homicide deaths in children

Purpose: To determine if household composition is an independent risk factor for fatal unintentional injuries related to child maltreatment., Design: A population-based, case-control study using data from the Missouri Child Fatality Review Program for 1992-1999., Methods: Children under age five who died during the 8-year study period were eligible for study. Cases were defined as children who died of an unintentional injury that occurred when a parent or other adult caregiver: (a) was not present, (b) was present but not capable of protecting the child, (c) placed the child in an unsafe sleep environment, or (d) failed to use legally mandated safety devices. Controls were randomly selected from children who died of natural causes. Household composition was classified based on relationship of the adults living in the household to the deceased child. The five household composition categories were households with: (a) two biologic parents and no other adults, (b) one biologic parent and no other adults, (c) one or two biologic parents and another adult relative, (d) stepparents or foster parents, and (e) one or two biologic parents and another unrelated adult. Logistic regression analyses were conducted and odds ratios estimating the risk of maltreatment-related unintentional death associated with each household category compared to the reference households: those with two biologic parents and no other adults., Findings: Three hundred eighty children met the case definition. Children residing within households with adults unrelated to them had nearly six times the risk of dying of maltreatment-related unintentional injury (adjusted odds ratio [aOR] 5.9; 95% confidence interval [95% CI] 1.9-17.6). Children residing with step or foster parents and those living with other, related adults were also at increased risk of maltreatment death (aOR 2.6, 95% CI 1.0-6.5; and aOR 2.1, 95% CI 1.0-4.5, respectively). Risk was not elevated for children in households with a single biologic parent and no other adults in residence., Conclusions: Young children residing in households with unrelated adults, step-parents, or foster parents are at increased risk of fatal unintentional injury related to maltreatment. Nurses can use the findings of this study to facilitate injury prevention by identifying families at risk for fatal unintentional injuries and providing these families with targeted education or referral.

Objective: To determine the role of household composition as an independent risk factor for fatal inflicted injuries among young children and describe perpetrator characteristics., Design, Setting, and Population: A population-based, case-control study of all children < 5 years of age who died in Missouri between January 1, 1992, and December 31, 1999. Missouri Child Fatality Review Program data were analyzed. Cases all involved children with injuries inflicted by a parent or caregiver. Two age-matched controls per case child were selected randomly from children who died of natural causes., Main Outcome Measure: Inflicted-injury death. Household composition of case and control children was compared by using multivariate logistic regression. We hypothesized that children residing in households with adults unrelated to them are at higher risk of inflicted-injury death than children residing in households with 2 biological parents., Results: We identified 149 inflicted-injury deaths in our population during the 8-year study period. Children residing in households with unrelated adults were nearly 50 times as likely to die of inflicted injuries than children residing with 2 biological parents (adjusted odds ratio: 47.6; 95% confidence interval: 10.4-218). Children in households with a single parent and no other adults in residence had no increased risk of inflicted-injury death (adjusted odds ratio: 0.9; 95% confidence interval: 0.6-1.9). Perpetrators were identified in 132 (88.6%) of the cases. The majority of known perpetrators were male (71.2%), and most were the child's father (34.9%) or the boyfriend of the child's mother (24.2%). In households with unrelated adults, most perpetrators (83.9%) were the unrelated adult household member, and only 2 (6.5%) perpetrators were the biological parent of the child., Conclusions: Young children who reside in households with unrelated adults are at exceptionally high risk for inflicted-injury death. Most perpetrators are male, and most are residents of the decedent child's household at the time of injury.

Background: Public health surveillance was established for nonfatal child maltreatment in Missouri using two data sources. This paper describes the epidemiology of nonfatal child maltreatment using this surveillance system, and assesses the usefulness of combining medical data with child protective services (CPS) reports for child maltreatment surveillance., Methods: Child abuse and neglect reports for children aged <10 years for 2000 were obtained from the Missouri Division of Family Services (DFS) and linked to hospital discharge and emergency department (ED) data for 2000. Children were classified as maltreated if they had an International Classification of Disease (ICD) maltreatment code for a hospital or ED visit, or a substantiated report to DFS. Validity of the ICD maltreatment codes was assessed in a 10% random sample of the hospital/ED visits. Medical records were reviewed to determine the accuracy of the maltreatment code assigned. The data analyses reported here were conducted in 2002 and 2003., Results: In the linked data, 5657 children met the case definition of maltreatment, providing a nonfatal maltreatment rate of 7.4/1000 children. Rates were higher among children aged <1 year (8.4/1000), females (7.7/1000), African Americans (11.8/1000), and children residing in rural counties (8.7/1000). The hospital/ED data identified proportionately more children who were African American, urban, physically abused, or infants, and uniquely identified only 10% of the total cases. In the validation sample, maltreatment was documented in 110 (87%) of the 127 records reviewed., Conclusions: CPS and medical data can be linked for surveillance. However, the medical data add few unique cases and identify only a subset of maltreated children.

Objective: Approximately 2000 children die annually in the United States from maltreatment. Although maternal and child risk factors for child abuse have been identified, the role of household composition has not been well-established. Our objective was to evaluate household composition as a risk factor for fatal child maltreatment., Methodology: Population-based, case-control study using data from the Missouri Child Fatality Review Panel system, 1992-1994. Households were categorized based on adult residents' relationship to the deceased child. Cases were all maltreatment injury deaths among children <5 years old. Controls were randomly selected from natural-cause deaths during the same period and frequency-matched to cases on age. The main outcome measure was maltreatment death., Results: Children residing in households with adults unrelated to them were 8 times more likely to die of maltreatment than children in households with 2 biological parents (adjusted odds ratio [aOR]: 8.8; 95% confidence interval [CI]: 3.6-21.5). Risk of maltreatment death also was elevated for children residing with step, foster, or adoptive parents (aOR: 4.7; 95% CI: 1.6-12.0), and in households with other adult relatives present (aOR: 2.2; 95% CI: 1.1-4.5). Risk of maltreatment death was not increased for children living with only 1 biological parent (aOR: 1.1; 95% CI: 0.8-2.0)., Conclusions: Children living in households with 1 or more male adults that are not related to them are at increased risk for maltreatment injury death. This risk is not elevated for children living with a single parent, as long as no other adults live in the home.
