Unraveling Pica in Children: The Link Between Eating Difficulties and Consuming Non-Food Items
The Prevalence and Risk Factors of Pica in Children
New research spearheaded by Cardiff University, in collaboration with other institutions, has shed light on the prevalence and risk factors of pica—an eating disorder characterized by the consumption of non-food items such as paper or soap—in children. Utilizing data from the Avon Longitudinal Study of Parents and Children, which included over 10,000 caregivers, the study found that pica was most prevalent in children at 36 months. Approximately 2.29% of caregivers reported pica behaviors in their children at this age.
The Association Between Pica and Autism or Developmental Delays
Furthermore, the study revealed that children with autism and developmental delays were more likely to exhibit pica behaviors. It also found an association between pica and sensory processing issues in these children. This groundbreaking discovery not only contributes to the understanding of pica’s prevalence in toddlers but also its association with autism and developmental delays.
Eating Difficulties as Potential Indicators of Pica
The research also highlighted that children who experience eating difficulties, such as undereating, overeating, and fussy eating, are more likely to develop pica. This was found to be true regardless of the child’s Body Mass Index (BMI), suggesting that pica behaviors may be associated with broader eating difficulties.
Implications for Clinicians and Caregivers
The findings of this study hold significant implications for clinicians and caregivers alike. Clinicians, for instance, should consider screening for pica behaviors in children of all weights and sizes, especially those who exhibit eating difficulties or have autism and developmental delays. This would help improve the diagnosis and support for affected children and their families.
Structural Barriers to Receiving Expert Medical Care
Another study on eating disorders (EDs) further underscores the importance of these findings. It revealed that three-quarters of youth with EDs received no diagnosis of an ED-related medical complication, with bradycardia being the most prevalent diagnosis suggestive of medical instability. Moreover, Latinx youth were found to be less likely to receive ED-related diagnoses suggestive of medical instability, highlighting structural barriers to receiving expert medical care for publicly insured youth with EDs.
The Broader Context of Child Health
Beyond the realm of eating disorders, research on child health and development also stresses the importance of considering environmental factors. A multi-university study found a link between fathers’ exposure to environmental toxins, particularly DDT, and health consequences for their children. Long-term exposure to DDT led to changes in the sperm epigenome, resulting in increased rates of birth defects and diseases. This underscores the urgency to find alternative ways to control malaria and other vector-borne diseases and highlights the importance of considering fathers in discussions about child health and development.
Improving Support for Children and Their Caregivers
Overall, these studies aim to provide better support for children who experience pica and their caregivers. By enhancing our understanding of the conditions that co-occur with pica and the broader context of child health and development, we can improve screening, diagnosis, and support systems, ultimately leading to better health outcomes for children.
