Summary
Premature infants born into adverse environments exhibit metabolic abnormalities, similar to full-term small for gestational age (SGA) infants. These findings highlight early life environment
Area of Science:
- Perinatal medicine
- Developmental origins of health and disease (DOHaD)
- Metabolic health
Background:
- Low birth weight, often indicating an adverse in utero environment, is linked to later-life diseases like type 2 diabetes and hypertension.
- Adverse perinatal environments are associated with reduced insulin sensitivity, with metabolic abnormalities observed in full-term small for gestational age (SGA) individuals from childhood to adulthood.
Purpose of the Study:
- To investigate metabolic abnormalities in premature infants exposed to adverse neonatal environments.
- To compare metabolic profiles of premature infants (both SGA and appropriate for gestational age [AGA]) with those of full-term SGA infants.
Main Methods:
- The study analyzed metabolic data from premature infants.
- Comparison of metabolic profiles between premature infants (SGA and AGA) and full-term SGA infants.
Main Results:
- Premature infants exposed to adverse neonatal environments demonstrate metabolic abnormalities.
- These abnormalities are present regardless of whether the premature infants are classified as SGA or AGA.
- The observed metabolic issues in premature infants resemble those seen in full-term SGA children.
Conclusions:
- Adverse neonatal environments contribute to metabolic abnormalities in premature infants.
- Prematurity and adverse neonatal conditions, independent of gestational age appropriateness, pose risks for metabolic health.
- Early life environment plays a crucial role in long-term metabolic programming, extending to premature births.
