Final answer:
Determining the percentage of infants in NICUs due to maternal issues requires local NICU data, but broader factors such as genetics and systemic health issues also significantly influence neonatal admissions and outcomes.
Step-by-step explanation:
To determine the percentage of infants in VBH's NICU due to a maternal issue, one needs to evaluate local data and research on neonatal care. However, based on the provided reference material, we can assert that maternal factors, while pertinent, are not the sole predictors of infant admissions to NICUs; genetic factors and the broader health care system also play significant roles.
For instance, we are informed that the majority of malformations leading to complications in live births are genetic, with only 10% attributed to environmental factors, including maternal health. Furthermore, the disparity in infant mortality rates (IMR) in the US, compared to countries like Finland or Cuba, suggest that systemic and sociopolitical issues, rather than direct maternal care, exert significant influence. Notably, the CDC's 2019 study highlights the increased pregnancy-related mortality among women of color, pointing to deeper societal issues influencing maternal and infant health.
