Insights
Low birthweight children face higher risks for physical and developmental issues. While medical home care did not alter this association, it improved health outcomes for all children, particularly those with low birthweight.
Area of Science:
- Pediatric Health Outcomes
- Public Health Research
- Healthcare Access and Equity
Background:
- Low birthweight is a known risk factor for adverse child health outcomes.
- The role of medical home in mitigating these risks requires further investigation.
- Understanding these associations is crucial for targeted public health interventions.
Purpose of the Study:
- To examine how medical home influences the link between low birthweight and children's health.
- To assess the prevalence of various health outcomes in relation to birthweight and medical home access.
- To identify potential disparities in health outcomes based on birthweight and healthcare access.
Main Methods:
- Analysis of the 2007 National Survey of Children's Health data (n=19,356).
- Inclusion of children aged 5 and under with mothers as primary respondents.
- Utilized logistic and ordinal regression models, controlling for sociodemographic factors.
Main Results:
- Low birthweight children showed higher prevalence of physical, developmental conditions, and fair/poor health.
- Medical home did not significantly modify the birthweight-health outcome association.
- Children without a medical home had higher prevalence of all studied outcomes.
- Medical home access was linked to improved outcomes for both normal and low birthweight children.
Conclusions:
- Low birthweight independently increases the risk of adverse health outcomes in young children.
- Medical home care is associated with better health outcomes, irrespective of birthweight.
- Further research on the adequacy and frequency of medical home care for low birthweight infants is warranted.
Abstract:
The objective of this study was to investigate the possible modifying effect of medical home on the association between low birthweight and children's health outcomes. The analytic sample included children 5 years and under from the 2007 National Survey of Children's Health whose mothers were the primary respondents and who had non-missing covariate information (n = 19,356). Controlling for sociodemographic factors, logistic and ordinal regression models estimated the presence of developmental, mental/behavioral or physical health outcomes, condition severity, and health status by birthweight, medical home, and their interaction. Prevalence estimates of physical, developmental, mental/behavioral and severe conditions among those with any conditions as well as fair/poor overall health were 8.9, 6.8, 2.4, 41.6, and 2.5 %, respectively. Overall, low compared to normal birthweight children had a higher prevalence of physical and developmental conditions and fair/poor health (15.2 vs. 8.3 %, 11.1 vs. 6.4 %, 4.5 vs. 2.3 %, respectively). Medical home did not significantly modify the effect of birthweight on health outcomes; however, prevalence of all outcomes was higher for children without a medical home. Adjusted models indicated that low birthweight children were almost twice as likely as normal birthweight children to have a physical or developmental condition and poorer overall health, regardless of having a medical home. Having a medical home was associated with equally improved health outcomes among normal and low birthweight children. Adequacy and frequency of medical home care should be investigated further, especially among low birthweight children.
