“…However, a significant single-peak cyclic trend in mortality rates was found for deaths from road accidents and drowning in July, which is the holiday season. A similar summer peak for traffic accidents, childhood drowning, and adolescent injury mortality was observed in Japan by Shinsugi and colleagues [23].…”

Aim: This ecological study was carried out to determine the cyclic trends in the rate of perinatal and infant mortality and among children aged under 15 years who died in traffic accidents or from drowning, respiratory disease or cancer. Methods: Monthly data on the numbers of live births, perinatal and infant deaths, and deaths from respiratory disease, cancer, traffic accidents, accidental drowning, and submersion in children aged under 15 years were obtained from the Hungarian nationwide population register. The data were aggregated over the study period and cyclic trends were investigated using the Walter-Elwood and negative binomial regression methods.

“…Previous studies showed children injury mortality may vary seasonally. Shinsugi et al [9] observed a summer peak for transport accidents and drowning mortality and more deaths in winter for asphyxia in Japanese children. However, few recent and comprehensive studies have examined the differences in under-15 children mortality by day of the week, school term and holidays.…”

“…The incidence of drowning deaths was higher in summer vacation than in spring and winter. It could be due to the more frequent swimming in rivers and the sea in summer which increased the risk of possible death [9]. Therefore, prevention measures such as wearing a personal floatation device, strengthening the supervision of children's activities, and teaching survival swimming and resuscitation skills should be implemented to reduce the drowning mortality [23].…”

“…Our findings also revealed that the drowning and transport accident deaths occurred more frequently on weekends than weekdays. This is most likely because children spend more time outside, playing on the road or swimming in a river on weekends and therefore the possibilities of drowning and transport accident deaths increased [9].…”

Background: This study analyzed the trends and seasonality in mortality among children aged 0-14 years in Guangzhou, China during 2008. Understanding the epidemiology of this public health problem can guide policy development for children mortality prevention. Methods:A population-based epidemiological retrospective study was conducted. 7,265 individual data of children mortality were obtained from the Guangzhou Centre for Disease Control and Prevention. The Poisson regression was used to quantify the annual average reduction rate and the difference in mortality rate between gender and age groups. Incidence ratios with 95% confidence intervals (CI) were calculated to determine the ratio of the observed number of deaths to the expected deaths (i.e. the average assuming no variations) by month, season, school term, weeks and holidays deaths.Results: Between 2008 and 2018, the children mortality rate in Guangzhou decreased from 54.0 to 34.3 per 100,000 children, with an annual reduction rate of 4.6% (95%CI:1.1%-8.1%), especially the under-5 mortality rate decreased by 8.3% (95%CI: 4.8%-11.6%) per year. The decline trend varied by causes of death, even with an upward trend for the mortality of asphyxia and neurological diseases. The risk of death among male children was 1.78 times (95%CI: 1.61-1.98) that of females. The distribution of causes of death differed by age groups. Maternal and perinatal, congenital and pneumonia were the top three causes of death in infants and cancer 3 accounted for 17% of deaths in children aged 1-14 years. Moreover, the injury-related mortality showed significant temporal variations with higher risk during the weekend. And there was a summer peak for drowning and a winter peak for asphyxia. Conclusions: Guangzhou has made considerable progress in reducing mortality over the last decade. The findings of characteristics of children mortality would provide important information for the development and implementation of integrated interventions targeted specific age groups and causes of death. mortality unchanged among the children aged 10-14 years. There children mortality rate was higher among males and those under five years. Significant temporal variations were observed for injury-related mortality from drowning, transport accidents and asphyxia. The upward trend of mortality due to asphyxia, neurological and cardiovascular diseases strengthens the importance of monitoring and management for specific causes of death. The findings provide important information for the development and implementation of interventions targeting specific causes, seasons and age groups to reduce children mortality.

Prevalence and Correlates of Suicide and Nonsuicidal Self-injury in Children

et al. 2022

IMPORTANCEConsiderably less is known about self-injurious thoughts and behaviors (SITBs) in preadolescence than older age groups, owing partly to the common view that young children are incapable of suicidal thoughts. Yet, preadolescent suicide has increased in recent years and is now the fifth leading cause of death in this age group, leading the National Institute of Mental Health to identify it as a priority for research and intervention.OBJECTIVE To assess prevalence estimates of preadolescent SITBs, identify correlates of these outcomes, and conduct head-to-head comparisons of preadolescent and adolescent SITBs in terms of associated characteristics.DATA SOURCES MEDLINE, PsycINFO, and Embase were systematically searched from inception through December 23, 2021, for studies on the prevalence and correlates of preadolescent SITBs. The search was restricted to English language publications and peer-reviewed journals.STUDY SELECTION Two reviewers independently identified studies providing data on prevalence and correlates of preadolescent SITBs.DATA EXTRACTION AND SYNTHESIS Two reviewers independently extracted data from each study, and the Joanna Briggs Institute Checklist for Prevalence Studies was used to assess study quality. Pooled prevalence and Cohen d were derived from random-effects meta-analyses. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was followed. MAIN OUTCOMES AND MEASURESPrevalence and correlates of suicidal ideation, suicide attempts, suicide deaths, and nonsuicidal self-injury among preadolescents.RESULTS Fifty-eight studies with 626 486 590 individuals were included. Lifetime prevalence of suicide in the general population was 0.79 per 1 million children. Prevalence for lifetime suicidal thoughts, suicide attempts, and nonsuicidal self-injury among preadolescents were 15.1%, 2.6%, and 6.2%, respectively, in community samples. These data suggest that approximately 17.0% of preadolescents with suicidal ideation transition to attempting suicide. Across several analyses, male individuals appear more likely to have SITBs in preadolescence than adolescence. Correlate data were modest for SITBs other than suicidal ideation, but among specific disorders, attention-deficit/hyperactivity disorder (suicidal ideation: d = 0.54 [95% CI, 0.34-0.75]) and depression (suicidal ideation: d = 0.90 [95% CI, 0.71-1.09]; suicide attempts: d = 0.47 [95% CI, 0.26-0.68]) emerged as the strongest correlates. Among interpersonal factors, child maltreatment (suicidal ideation: d = 2.62 [95% CI, 1.56-3.67]) and parental support (suicidal ideation: d = −0.34 [95% CI, −0.46 to −0.22]) yielded the largest effect sizes. CONCLUSIONS AND RELEVANCEIn this systematic review anda meta-analysis, although preadolescent suicide deaths were rare, other SITB types occur with concerning frequency. Male individuals were at greater risk for SITBs in preadolescence relative to adolescence. Attention-deficit/hyperactivity disorder, child maltreatment, and parental support were especially...
