Insights
Anemia affects 2.7% of children in Pennsylvania foster care. Anemia is linked to developmental delays and behavioral issues, including adjustment disorder and irritability.
Area of Science:
- Pediatric Health
- Child Development
- Public Health
Background:
- Children in foster care are a vulnerable population with significant physical and mental health challenges.
- Nutritional status, particularly anemia, is understudied in this population.
- Few studies have quantified anemia prevalence or examined its link to developmental and behavioral outcomes in U.S. foster care.
Purpose of the Study:
- To determine the prevalence of anemia in children aged six months to ten years in or adopted from Pennsylvania foster care.
- To investigate the association between anemia status and developmental and behavioral diagnoses in this cohort.
Main Methods:
- Secondary data analysis of the Medicaid Analytic eXtract database (2010-2015).
- Inclusion criteria: Children aged six months to ten years in or adopted from Pennsylvania foster care.
- Logistic regression used to calculate adjusted odds ratios for health outcomes.
Main Results:
- A total of 50,311 children were analyzed; 2.7% (1,365) had anemia.
- Children with anemia showed higher odds of delayed milestones (AOR: 2.38), specific developmental delays (AOR: 1.59), adjustment disorder (AOR: 1.59), and irritability (AOR: 10.57).
Conclusions:
- Anemia prevalence in Pennsylvania foster care children aligns with national rates.
- Anemia is associated with increased odds of developmental delays and behavioral diagnoses in children in foster care.
Background:
Children in foster care are classified as a highly vulnerable population and struggle with both physical and mental health problems. Medical conditions, like poor nutritional status, remain understudied in children in foster care. To our knowledge, few studies in children in U.S. foster care have quantified the prevalence of anemia, and no studies have examined the association between anemia status and relevant developmental and behavioral outcomes.
Objective/Aims:
(1) To determine the prevalence of anemia among children in or adopted from Pennsylvania foster care, between the ages of six months to ten years and (2) To examine if a child's anemia status is associated with greater odds of relevant developmental and behavioral diagnoses.
Methods:
We conducted a secondary data analysis utilizing the Medicaid Analytic eXtract database between 2010-2015. Children six months-ten years were included in the analysis if they were in or had been adopted from Pennsylvania foster care. Logistic regression was used to calculate adjusted odds ratios (AOR) with 95% confidence intervals for the association between iron status and health outcomes.
Results:
A total of 50,311 children were included in our sample, of which 1,365 children (2.7%) were diagnosed with anemia. Children diagnosed with anemia had greater odds of delayed milestones (AOR: 2.38 [1.64-3.45]), specific delays in development (AOR: 1.59 [1.23-2.07]), adjustment disorder (AOR: 1.59 [1.06-2.39]), and irritability (AOR: 10.57 [3.36-33.25]), than children not diagnosed with anemia.
Conclusion:
The prevalence of anemia among children between six months-ten years in or adopted from the Pennsylvania foster care system is within the national rate of U.S. childhood anemia. Odds of several relevant developmental and behavioral diagnoses were greater among children diagnosed with anemia than children who were not.
