Late Diagnosis in the Era of Universal Newborn Screening Negatively Affects Short- and Long-Term Growth and Health Outcomes in Infants with Cystic Fibrosis.

Newborn screening for cystic fibrosis was fully implemented in the US by 2010, but delays in timeliness of evaluation for infants with positive newborn screening tests persist. Through evaluation of national patient registry data, we determined that late initiation of cystic fibrosis care is associated with poorer long-term nutritional outcomes.
