Dermatoglyphics and aging.

The objectives of the present study were to compare the frequencies of various dermatoglyphic features among male adults of four different age groups (30-44 years of age, 45-59, 60-74, and 75 years of age and older) and to compare the dermatoglyphic frequencies of a sample of normal 7-year-old males with those of each of the four adult groups. The results indicated that, for the most part, the four adult groups had very similar dermatoglyphic frequencies. The dermatoglyphics of the 7-year-olds were also found to be very similar to those of the 30- to 44-year-old adults; however, they showed, progressively, more significant dermatoglyphic differences as they were compared with succeedingly older age groups.
