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

Abstract

Aims - To test the null hypotheses that finger and palm prints have no relation with fetal growth or adolescent blood pressure. Methods - All 128 singleton, unimpaired, very low birth weight (VLBW; ≤1500 g) infants born to mothers resident in the county of Merseyside in 1980 and 1981 were studied retospectively. The comparison group consisted of 128 age, sex, and school matched children. Main outcome measures were blood pressure at age 15 years, birth weight ratio, fingerprint patterns, and palmar AtD angles. Results - The VLBW index population had a significantly higher systolic blood pressure than the comparison group (mean difference 3.2 mm Hg). The difference in diastolic blood pressure between the VLBW index and the matched comparison group was not significant. No significant differences were found in the palmar AtD angles or in the fingerprint proportions of arches, loops, and whorls and no correlation was found between fingerprint patterns and blood pressure. Among the VLBW index population, both height and right palmar AtD angle were independently and significantly correlated with and explained 12.1% of the variance in the systolic blood pressure. Birth weight ratio, as a measure of fetal growth restriction, had no significant correlation with systolic blood pressure. Conclusions - The higher systolic blood pressure of adolescents who were of very low birth weight compared with the matched comparison group is not associated with fingerprint patterns or birth weight ratio as markers for fetal growth restriction.
