Importance Suicide is a leading cause of death among youths. The relationship between mental health, psychosocial factors and youth suicidality needs further analysis. Objective To describe paediatric suicide in the USA and the impact of mental health and substance abuse using the National Child Death Review Case Reporting System (CDR-CRS). To identify psychosocial correlates contributing to suicide and whether these factors are more common among individuals with history of menta illness or substance abuse. Design Deidentified data (CDR-CRS) from 2004 to 2012 was obtained from 29 participating states. Demographic data and psychosocial correlates, including age, gender, cause of death, history of mental illness and/or substance abuse, school concerns, previous suicide attempts and family history of suicide, were collected. Results A total of 2850 suicides were identified. Mean age was 15.6±1.9 years; (range 7-21 years) 73.6% male and 65.1% Caucasian. The leading causes of death were asphyxia (50.2%) and weapon/firearm (36.5%). Among all subjects, 25.5% had history of mental illness and 19.0% had history of substance abuse. 60.0% had no report of mental illness or substance abuse. Subjects with both mental illness and substance abuse were more likely to have school concerns (OR=4.1 (p<0.001)), previous suicide attempts (OR=4.2 (p<0.001)) and a family history of suicide (OR=3.2 (p<0.001)) compared with subjects without those characteristics. Conclusions Most suicide records in the CDR-CRS had no indication of mental illness or substance abuse. The youth with mental-illness/substance-abuse issues were more likely to have other compounding psychosocial correlates that may be warning signs of suicide. [ABSTRACT FROM AUTHOR]

Background Drowning is the second leading cause of unintentional injury death among US children. Multiple studies describe decreased drowning risk among children possessing some swim skills. Current surveillance for this protective factor is self/proxy-reported swim skill rather than observed inwater performance; however, children's self-report or parents' proxy report of swim skill has not been validated. This is the first US study to evaluate whether children or parents can validly report a child's swim skill. It also explores which swim skill survey measure(s) correlate with children's inwater swim performance. Methods For this cross-sectional convenience-based sample, pilot study, child/parent dyads (N=482) were recruited at three outdoor public pools in Washington State. Agreement between measures of self-reports and parental-reports of children's swim skill was assessed via paired analyses, and validated by inwater swim test results. Results Participants were representative of pool's patrons (ie, non-Hispanic White, highly educated, high income). There was agreement in child/parent dyads' reports of the following child swim skill measures: 'ever taken swim lessons', perceived 'good swim skills' and 'comfort in water over head'. Correlation analyses suggest that reported 'good swim skills' was the best survey measure to assess a child's swim skill--best if the parent was the informant (r=0.25-0.47). History of swim lessons was not significantly correlated with passing the swim test. Conclusions Reported 'good swim skills' was most correlated with observed swim skill. Reporting 'yes' to 'ever taken swim lessons' did not correlate with swim skill. While non-generalisable, findings can help inform future studies. [ABSTRACT FROM AUTHOR]

Background Childhood falls are an important global public health problem, but there is lack of evidence about their prevention. Falls on one level result in considerable morbidity and they are costly to health services. Objective To estimate ORs for falls on one level in children aged 0-4 years for a range of safety behaviours, safety equipment use and home hazards. Design, setting and participants Multicentre case-control study at hospitals, minor injury units and general practices in and around four UK study centres. Participants included 582 children less than 5 years of age with a medically attended fall injury occurring at home and 2460 controls matched on age, sex, calendar time and study centre. Main outcome measure Fall on one level. Results Cases' most common injuries were bangs on the head (52%), cuts or grazes not needing stitches (29%) or cuts or grazes needing stitches (17%). Comparing cases to community controls in the adjusted analyses, significant findings were observed for only two exposures. Injured children were significantly less likely to live in a household without furniture corner covers (adjusted OR (AOR) 0.72, 95% CI 0.55 to 0.95), or without rugs and carpets firmly fixed to the floor (AOR 0.76, 95% CI 0.59 to 0.98). Conclusions We did not find any safety practices, use of safety equipment or home hazards associated with a reduced risk of fall on one level. Our findings do not provide evidence to support changes to current injury prevention practice. [ABSTRACT FROM AUTHOR]

Objective The aim of this study was to compare parents' expectations for their children crossing streets' with children s actual crossing behaviours and determine how accurately parents judge their own children's pedestrian behaviours to be. Method Using a fully immersive virtual reality system interfaced with a 3D movement measurement system, younger (7-9 years) and older (10-12 years) children's crossing behaviours were assessed. The parent viewed the same traffic conditions and indicated if their child would cross and how successful she/he expected the child would be when doing so. Results Comparing children's performance with what their parents expected they would do revealed that parents significantly overestimated the inter-vehicle gap threshold of their children, erroneously assuming that children would show safer pedestrian behaviours and select larger inter-vehicle gaps to cross into than they actually did; there were no effects of child age or sex. Child and parent scores were not correlated and a logistic regression indicated these were independent of one another. Conclusions Parents were not accurate in estimating the traffic conditions under which their children would try and cross the street. If parents are not adequately supervising when children cross streets, they may be placing their children at risk of pedestrian injury because they are assuming their children will select larger (safer) inter-vehicle gaps when crossing than children actually do.

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.

Background SwimSafe, a basic swimming and safer rescue curriculum, has been taught to large numbers of Bangladeshi children since 2006. This study examines the frequency and characteristics of rescues reported by children who graduated from SwimSafe and compares them with age-matched and sex-matched children who did not participate in SwimSafe. Methods Interviews were conducted during the swimming season in Raiganj, Bangladesh. Data were collected from 3890 SwimSafe graduates aged 6-14. Two age-matched and sex-matched controls were selected; one who had learned to swim naturally, the other who had not learned to swim. Results 188 rescues were reported by the three groups. The 12-14-year age groups reported the highest monthly rate of rescues (SwimSafe 10.5/100 000 (95% CI 3.4 to 24.5), natural swimmers 8.5/100 000 (95% CI 2.2 to 21.2)) and annual rate of rescue reported (SwimSafe 25.4/100 000 (95% CI 13.2 to 43.9), natural swimmers 35.4/100 000 (20.8 to 56.2)). Reported rescue numbers among both swimming groups was similar. Mean victim age was 4.1 years and 92.5% were under 7 years. All victims were younger than their rescuer (mean 5.9 years less). Most rescues (73.7%) took place in ponds or ditches with most (86.6%) within 10 m of the bank. Most victims had entered the water to bathe (53.8%). A large majority of reported rescues (90.9%) were conducted with the rescuer in the water, half requiring the rescuer to swim. Conclusions Children report frequent drowning rescues of younger children in rural Bangladesh. Most reported are contact rescues with the rescuer in the water. Formal training for in-water rescue techniques may be needed to reduce the risk to the child rescuer. [ABSTRACT FROM AUTHOR]

Background. Much of the research on child injury risk has focused on trait-like factors (eg, hyperactivity, child gender) that influence injury risk rather than state-like factors (eg, environmental circumstances, child behaviour). Additional research is needed to better identify the proximal risk factors for children’s risk for unintentional injury. Objectives. The present study examined the antecedents to minor unintentional injury events and whether unusual circumstances and child behaviour predicted injury risk. Methods. The study used archival data that were collected via biweekly in-person interviews with 170 mothers of toddlers (15–36 months) for 6 months. A case crossover design was used to predict children’s risk for injury from proximal risk factors. Results. Children were at a higher risk for injury when circumstances were unusual and when they were engaging in an unusual behaviour. When a child was engaging in an unusual behaviour, higher levels of maternal supervision predicted lower injury risk. Children were more likely to be injured in a new environment, in an environment with animals or other people, in an environment with hazards or when engaging in a new activity or in a familiar activity performed in an unfamiliar way. Conclusions. The results indicate that toddlers may be at a greater risk for minor unintentional injury when environmental circumstances are outside of the norm or when a child is engaging in unusual behaviours. The findings also indicate that higher levels of caregiver supervision may be especially beneficial when children are engaging in new or unfamiliar activities. [ABSTRACT FROM AUTHOR]
