Brief Summary

In this observational pilot project, the investigators plan to document duration and sources of exposure to plasticizers in infants born at birth weights less than 1500 grams. The investigators will examine the association between exposure to plasticizers and outcomes such as performance on a neurological screening tool, extrauterine growth, and thyroid function.

Conditions

Low Birth Weight Neonates

Keywords

Low birth weight neonates; Neurodevelopmental outcome; Thyroid dysfunction; Extrauterine growth; Plasticizers

Outcome Measures

Primary Outcomes (3)

Secondary Outcomes (2)

• Extrauterine growth

  Weekly during NICU stay with average stay of 8-10 weeks

• Thyroid dysfunction
