Insights
Child development stage significantly impacts poisoning risk in young children. Younger children (12-17 months) are more prone to non-medicinal poisonings, while older children (24-41 months) face higher risks from medicinal substances.
Area of Science:
- Pediatrics
- Toxicology
- Developmental Psychology
Background:
- Poisoning risk in children aged 0-4 years is often analyzed as a single group, masking critical differences in substance type based on age.
- These differences are linked to developmental stages, but prior research has not examined developmental stage's predictive value for poisoning by substance type.
Purpose of the Study:
- To investigate the predictive value of child developmental stage for poisoning by substance type in children aged 0-4 years.
- To utilize 3-month age intervals as a proxy for developmental stage, adjusting for sex, socioeconomic status, and remoteness.
Main Methods:
- A population-based dataset of unintentional poisoning hospitalizations in children aged 0-4 years was analyzed.
- Multivariate logistic regression was used to assess associations between substance type and age, sex, socioeconomic status, and remoteness.
Main Results:
- Children aged 12-17 months had significantly higher odds of non-medicinal poisoning.
- Children aged 24-41 months had significantly higher odds of medicinal poisoning.
- Males and children from disadvantaged or remote areas had increased odds of non-medicinal poisoning.
Conclusions:
- Child development stages influence children's environmental access and subsequent poisoning risks.
- The likelihood of medicinal versus non-medicinal poisoning changes significantly with age.
- Child development is a significant predictor of the type of substance a child may access and ingest.
Background:
When children aged 0-4 years are analysed together as a group for poisoning risk, important differences for smaller age intervals by medicinal and non-medicinal substances are masked. These differences have been attributed to child developmental stages but no studies have been conducted that examine the predictive value of child developmental stage for poisoning by substance type, using 3-month age intervals as a proxy for developmental stage and adjusting for the effect of sex, socio-economic status and remoteness of residence.
Methods:
A population-based dataset of unintentional poisoning hospitalizations in children aged 0-4 years was used to predict the type of substance ingested. Associations between the type of substance and age, sex, socio-economic status and remoteness of residence were measured using multivariate logistic regression.
Results:
Children aged 12-17 months had significantly higher odds of experiencing a non-medicinal poisoning while children aged 24-41 months had significantly higher odds of experiencing a medicinal poisoning. Males and children from more disadvantaged and outer regional areas had higher odds of experiencing a non-medicinal poisoning.
Conclusions:
Children aged 0-4 years differ in their stage of development and as a consequence, vary significantly in their ability to access their environment. Our results clearly show that odds of poisoning by medicinal substances compared with non-medicinal substances change as children age. This study provides evidence that child development predicts the type of substance accessed and ingested.
