Early growth in offspring of diabetic mothers

Area of Science:

• Pediatric Endocrinology
• Metabolic Health
• Human Growth and Development

Background:

• Offspring of diabetic mothers (ODMs) often show altered metabolic profiles and increased adiposity.
• Early life growth patterns are critical determinants of long-term health outcomes.

Purpose of the Study:

• To investigate the longitudinal growth patterns of offspring of diabetic mothers (ODMs) from birth up to 7.7 years of age.
• To compare growth trajectories between ODMs and offspring of mothers without diabetes (non-DMs).

Main Methods:

• Longitudinal anthropometric measurements (z scores) including birth weight, length/height, and relative weight (RW) were collected from birth, 1.5 years, and 7.7 years.
• Pima Indian children were stratified based on maternal diabetes status.
• Statistical analyses adjusted for gestational age at delivery.

Main Results:

• Gestational age-adjusted birth weight was significantly higher in ODMs compared to non-DMs.
• ODMs experienced a 'catch-down' in weight z scores and reduced height at 1.5 years.
• By 7.7 years, ODMs were heavier than non-DMs, with similar height, and metabolic differences were linked to relative weight.

Conclusions:

• Offspring of diabetic mothers (ODMs) display a unique growth trajectory characterized by higher birth weight and a subsequent period of reduced growth, followed by accelerated weight gain.
• These distinct growth patterns in ODMs highlight the impact of maternal diabetes on fetal and childhood development.
• The findings underscore the importance of monitoring growth and metabolic status in ODMs throughout childhood.
