Risk factors for unintentional poisoning in children aged 1-3 years in NSW Australia: a case-control study.

BACKGROUND: Unintentional poisoning in young children is an important public health issue. Age pattern studies have demonstrated that children aged 1-3 years have the highest levels of poisoning risk among children aged 0-4 years, yet little research has been conducted regarding risk factors specific to this three-year age group and the methodologies employed varied greatly. The purpose of the current study is to investigate a broad range of potential risk factors for unintentional poisoning in children aged 1-3 years using appropriate methodologies. METHODS: Four groups of children, one case group (children who had experienced a poisoning event) and three control groups (children who had been 'injured', 'sick' or who were 'healthy'), and their mothers (mother-child dyads) were enrolled into a case-control study. All mother-child dyads participated in a 1.5-hour child developmental screening and observation, with mothers responding to a series of questionnaires at home. Data were analysed as three case-control pairs with multivariate analyses used to control for age and sex differences between child cases and controls. RESULTS: Five risk factors were included in the final multivariate models for one or more case-control pairs. All three models found that children whose mothers used more positive control in their interactions during a structured task had higher odds of poisoning. Two models showed that maternal psychiatric distress increased poisoning risk (poisoning-injury and poisoning-healthy). Individual models identified the following variables as risk factors: less proximal maternal supervision during risk taking activities (poisoning-injury), medicinal substances stored in more accessible locations in bathrooms (poisoning-sick) and lower total parenting stress (poisoning-healthy). CONCLUSIONS: The findings of this study indicate that the nature of the caregiver-child relationship and caregiver attributes play an important role in influencing poisoning risk. Further research is warranted to explore the link between caregiver-child relationships and unintentional poisoning risk. Caregiver education should focus on the benefits of close interaction with their child as a prevention measure.

Leading causes of injury hospitalisation in children aged 0-4 years in New South Wales by injury submechanism: a brief profile by age and sex.

AIM: To identify the leading causes of injury in children aged 0-4 years by single year of age using injury submechanisms and present a brief epidemiologic profile of each cause. METHODS: Hospitalisation data for New South Wales from 1999 to 2009 were used to identify the leading causes of injury for children aged 0-4 years by single year of age. For each leading cause, rates over time and by sex were calculated by single year of age. Associated age and sex risk ratios were estimated. RESULTS: The leading causes of injury for children aged <1, 1 and 2 years were falls while being carried, burns by hot non-aqueous substances and poisoning by other and unspecified pharmaceutical substances, respectively. Falls involving playground equipment ranked first for children aged 3-4 years. Each leading injury cause exhibited an age pattern that remained stable over time and by sex. Age predicted falls while being carried and both age and sex predicted the remaining leading injury causes, with age and sex interacting to predict burns by hot non-aqueous substances. CONCLUSIONS: Epidemiologic analysis using single-year age intervals and injury submechanisms results in a clearer picture of injury risk for young children. The findings of this study provide detailed information regarding the leading causes of hospitalised injury in young children by age and sex. Child health-care providers can use this information to focus discussions of child development and injury risk with families of young children and suggest appropriate prevention measures in terms of a child's age and sex.

Trends and future projections of child injury in New South Wales: A tool for advocacy?

AIMS: To describe the trend of unintentional hospitalised injury in children aged 0-14 years in New South Wales (NSW), Australia during 1993-1994 to 2004-2005 and to estimate future projections of common child injury hospitalisations from 2006 to 2021. METHODS: NSW hospitalisation data were used to describe injury trends of children aged 14 years or less who were residents of NSW (1993-1994 to 2004-2005). Projected injury-related hospitalisations of children for 2006-2021 were estimated assuming that the current observed rate of change in childhood injury hospitalisation rates continued to 2021. RESULTS: During 1993-1994 to 2004-2005, there were 238 093 injury-related hospitalisations of children aged 14 years or less in NSW. Assuming the rate of change in injury hospitalisation observed between 1993-1994 and 2004-2005 continued into the future, the all hospitalised injury incidence rate for children aged 14 years or less is projected to decrease by 1.0% each year to 2021. Injury mechanisms such as burns and scalds, swimming pool non-fatal drowning and poisoning are all projected to decrease in the future, although not for all age groups. Falls (excluding those from playground equipment) and falls from playground equipment hospitalisations (excluding children less than 1 year) are projected to increase. CONCLUSION: Although the incidence of hospitalisation for some common child-related injury mechanisms is projected to decrease over the coming years, others are projected to increase. It is possible that advocacy efforts might benefit from using projected injury trends. Co-ordinated cross-government action is needed to successfully implement child injury prevention strategies, particularly in the playground environment.
