Age in months and birth order in infant nonfatal injuries: A retrospective cohort study

Adolescent delinquency following co-occurring childhood head injuries and conduct problem symptoms: findings from a UK longitudinal birth cohort

Childhood conduct problems and head injuries share a bidirectional association, but how this affects the risk of adolescent delinquency is unknown. Due to their similar underlying mechanisms (i.e. increased impulsivity), this study aims to identify whether their co-occurrence increases the risk of adolescent delinquency. Data was obtained from 11,272 children at age 14 and 10,244 at age 17 years enrolled in the UK Millennium Cohort Study. Conduct problem symptoms (via the Strengths and Difficulties Questionnaire) and head injuries were parent reported from ages 3 to 14 years. Delinquency was self-reported at ages 14 and 17 including substance use, criminality, and antisocial behaviour. Incident rate ratios (IRR) were estimated for delinquency at ages 14 and 17 by childhood conduct problem and head injury status. Co-occurring head injuries and high conduct problem symptoms presented the greatest risk for overall delinquency and substance use at age 14 compared to those with the presence of one or neither (IRRs from 1.20 to 1.60). At age 17, conduct problems (with or without co-occurring head injuries) presented the greatest risk for overall delinquency, substance use, and antisocial behaviour. There was no evidence for an increased risk of delinquency at ages 14 or 17 following a head injury only. Whilst these findings suggest childhood head injuries alone do not increase the risk of adolescent delinquency, when co-occurring alongside high conduct problem symptoms there is a heightened earlier risk. These results provide further insight into adolescent delinquency and the outcomes of co-occurring childhood head injury and conduct problem symptoms.

Association between obtaining injury prevention information and maternal and child health services during COVID-19

BACKGROUND

Coronavirus disease 2019 disrupted the delivery of public maternal and child health services to caregivers of preschool children, leading to decreased opportunities for injury prevention education. We aim to 1) explore the timing, content, and methods of providing injury prevention information desired by pregnant women and mothers and 2) identify mothers who experienced difficulty in obtaining injury prevention information owing to reduced maternal and child health services.

METHODS

From March 24 to 29, 2022, we conducted a population-based cross-sectional study and web-based survey. Of the registered monitors of the internet research company Rakuten Insight, 675 mothers raising their first child aged 0-2 during the COVID-19 period (February 2020 to March 2022) were included in the analysis.

RESULTS

Over half of the mothers wanted injury prevention information throughout their pregnancy. They preferred receiving information through traditional face-to-face services provided by local governments, such as antenatal classes or checkups. However, 34.1% of mothers said they did not obtain the information they needed; this was particularly true of unemployed mothers, had children aged 0-1, and had children with illnesses requiring hospital visits.

CONCLUSIONS

Mothers who could not obtain injury prevention information were originally disadvantaged mothers concerning access to information. The decrease in maternal and child health services may have widened this information gap. These findings can inform recommendations for caregivers, particularly those susceptible to information gaps during emergencies, and offer insights into future injury prevention education strategies.

The bidirectional relationship between head injuries and conduct problems: longitudinal modelling of a population-based birth cohort study

Childhood head injuries and conduct problems increase the risk of aggression and criminality and are well-known correlates. However, the direction and timing of their association and the role of their demographic risk factors remain unclear. This study investigates the bidirectional links between both from 3 to 17 years while revealing common and unique demographic risks. A total of 8,603 participants (50.2% female; 83% White ethnicity) from the Millennium Cohort Study were analysed at 6 timepoints from age 3 to 17. Conduct problems were parent-reported for ages 3 to 17 using the Strengths and Difficulties Questionnaire (SDQ) and head injuries at ages 3 to 14. A cross-lagged path model estimated the longitudinal bidirectional effects between the two whilst salient demographic risks were modelled cumulatively at three ecological levels (child, mother, and household). Conduct problems at age 5 promoted head injuries between 5 and 7 (Z = 0.07; SE = 0.03; 95% CI, 0.02-0.13), and head injuries at ages 7 to 11 promoted conduct problems at age 14 (ß = .0.06; SE = .0.03; 95% CI, 0.01-0.12). Head injuries were associated with direct child-level risk at age 3, whereas conduct problems were associated with direct risks from all ecological levels until 17 years. The findings suggest a sensitive period at 5-11 years for the bidirectional relationship shared between head injuries and conduct problems. They suggest that demographic risks for increased head injuries play an earlier role than they do for conduct problems. Both findings have implications for intervention timing.

Evaluation of Infant Injury Prevention Education Provided during Antenatal Classes after Two Years: A Pilot Prospective Cohort Study

This study examined the long-term effects of an infant injury prevention program implemented during an antenatal class of 131 mothers. Questionnaires were completed 2 years postpartum to assess the incidence of injury (medically attended or home-care), mothers' perception of injury prevention, implementation of safety practices, and active attitudes toward injury prevention. Responses were obtained from 68 (51.9%) mothers (intervention group, 40; control group, 28), including 24 who reported medically attended injuries and 55 who reported home-care injuries. The incidence of medically attended injuries did not differ between groups. The incidence of home-care injuries was also not significantly different, but was lower in the intervention group (72.5% vs. 92.9%, p = 0.050). Significantly fewer children in the intervention group experienced "injury due to being caught between objects" (12.5% vs. 39.3%, p = 0.014). Mothers in the intervention group were significantly more aware of injury prevention than those in the control group (p = 0.033). The risk of home-care injuries was inversely related to mothers' injury-prevention perception (odds ratio [OR]: 0.55, p = 0.035). This study suggests that group education during pregnancy regarding injury prevention increases mothers' perception of injury prevention. These findings support implementing injury prevention education during antenatal classes.

Infant Injury Prevention Education for Pregnant Women Attending Antenatal Class: A Quasi-Experimental Study

It is important to educate caregivers in order to prevent infant injuries. However, there have been few studies on the effects of education on pregnant women. This study aimed to evaluate the effects of injury prevention group education on this group. Study participants were recruited from a group of pregnant mothers attending an antenatal class in Tokyo. Participants were assigned to either the intervention or control group based on the month in which they attended the existing antenatal class. Both groups received a leaflet on injury prevention, but only the intervention group received an additional short one-shot lecture. The implementation of each of the nine safety practices was assessed during home visits after childbirth. Of the 131 study participants (56 in the control group and 75 in the intervention group), 106 (80.9%) received home visits after birth. Mothers in the intervention group implemented three practices significantly more than those in the control group: Keep soft objects away from the baby's head (38.3% vs. 13.0%), Do not place your baby on a high surface (74.6% vs. 52.2%), and Use the baby carrier correctly (93.3% vs. 76.1%). In the future, we plan to follow up the participants to evaluate the program's long-term effects, and to continue to improve the program.

Pregnant Women's Intentions to Implement Safety Practices for Preventing Infant Injury: A Cross-Sectional Study

Injury prevention education for pregnant women may be beneficial for infants' safety. Currently, knowledge about the scope of an expectant mother's intent to prevent injury is limited. The objective of this study was to determine pregnant women's intentions to implement infant injury prevention strategies. From May to June 2017, a self-administered questionnaire based on the precaution adoption process model was distributed among pregnant women who participated in a parenting preparation class in a city, Tokyo. Pregnant women's intentions to implement the following eight kinds of safety practices were measured: three practices regarding suffocation, two regarding falls, one safety practice for burns, one for accidental ingestion, and one for traffic accidents. Among 132 respondents (response rate: 83.5%; mean age: 33.4 years; mean gestational age: 29 weeks), the most common unawareness issue was "Make sure that there is no space between the mattress and bed frame" (68.2%), followed by "Use a firm mattress or futon" (38.5%) and "Keep soft objects away from the baby's head in the baby's sleep area" (31.8%); 58% or more women reported having already "decided to implement" the other five practices. Safety practices that pregnant women were mostly unaware of were for preventing suffocation, despite this being a leading cause of death in terms of unintentional infant injury. In comparison, the safety practices for falls, burns, and accidental ingestion were more known to pregnant women. The pregnant women's intention to implement injury prevention for infants varied by safety practices. These findings could be used to improve the focus of antenatal education programs for the prevention of infant injury.
