Big infants in the neonatal intensive care unit.

Objective: This study was undertaken to identify risk factors for prolonged neonatal intensive care unit (NICU) stay in macrosomic (> or = 4000 g) neonates.

Study Design: A population-based case-control study in which 799 cases of macrosomic neonates with a prolonged NICU stay were compared with macrosomic neonates without a prolonged stay (n = 1598).

Results: Significant risk factors included: 5-minute Apgar score less than 7: odds ratio (OR) = 43.

Use of home visit and developmental clinic services by high risk Mexican-American and white non-Hispanic infants.

Objective: To investigate whether US-born infants of mothers of Mexican descent who were enrolled in Arizona's Newborn Intensive Care Program (NICP) received follow-up services (developmental clinic and community health nurse [(CHN)] home visits) at the rates similar to White non-Hispanic (WNH) infants. Socio-economic and health status characteristics were controlled using stepped regressions in order to assess the impact of each on service use.

Methods: This population-based study used retrospective data from the NICP administrative database that were linked to birth certificates for years 1994-1998.
