Dermatoglyphic patterns, very low birth weight, and blood pressure in adolescence

Area of Science:

• Developmental origins of health and disease (DOHaD)
• Pediatric cardiology
• Human genetics

Background:

• Very low birth weight (VLBW) infants are at increased risk for adverse health outcomes.
• Fetal growth restriction is a significant concern in VLBW neonates.
• The relationship between early life factors and later cardiovascular health is an area of active research.

Purpose of the Study:

• To investigate the association between fingerprint patterns, fetal growth restriction, and adolescent blood pressure in very low birth weight (VLBW) survivors.
• To test the hypotheses that dermatoglyphic features and birth weight ratio correlate with adolescent blood pressure in VLBW individuals.

Main Methods:

• Retrospective study of 128 VLBW infants and 128 matched controls born in Merseyside, 1980-1981.
• Assessment of blood pressure at age 15 years, birth weight ratio, fingerprint patterns, and palmar AtD angles.
• Statistical analysis to determine correlations and variance explained.

Main Results:

• VLBW survivors exhibited significantly higher systolic blood pressure (mean difference 3.2 mm Hg) compared to controls.
• No significant differences in palmar AtD angles or fingerprint patterns (arches, loops, whorls) were observed between groups.
• Fingerprint patterns did not correlate with blood pressure; however, height and right palmar AtD angle explained 12.1% of systolic blood pressure variance in VLBW individuals.

Conclusions:

• The elevated systolic blood pressure in adolescents born with VLBW is not linked to fingerprint patterns or birth weight ratio as indicators of fetal growth restriction.
• These findings suggest that other factors beyond dermatoglyphics and fetal growth restriction contribute to the cardiovascular risk in VLBW survivors.
