Abstract
Introduction: Dermatoglyphics is the scientific study of the skin ridge patterns on the fingers, palms and
soles of human. Dermatoglyphics patterns are genetically determined and affected by physical,
topographical and environmental factors in intrauterine life. There are lines in the palm known as palmar
creases. A normal human palm contains three major creases. The patterns of the epidermal ridges and
palmar creases serve as a diagnostic tools in a number of diseases that have genetic backgrounds.
Diabetes mellitus is one such of diseases with a strong genetic basis and certain dermatoglyphics and
palmar crease variations are expected to occur.
Objectives: The aim of this study is to determine the prevalence of digital dermatoglyphics and palmar
crease patterns of the hand among diabetics and non-diabetics patients in governmental hospitals, East
Gojjam zone, 2019
Methods: Institution based cross-sectional study was conducted by both observation and interview
methods. Bilateral palmar and fingerprints were taken by mobile camera from selected volunteers of
diabetic and non-diabetic subjects attending East Gojjam zone government hospitals. A Pearson chisquare
test, bivariable, and multivariable multinomial logistic regression models were employed using
SPSS version 20. Odds ratio with 95% confidence interval was computed and p-values less than 0.05
were considered significant.
Result: In both diabetics and non-diabetic subjects loop type was the most frequent followed by whorl
and arch types. Their prevalence were respectively 66.9% [95% CI: 65.4, 68.3], 28.4% [95%CI: 27, 29.8],
and 5.1% [95% CI: 4.1, 5.4] in diabetics and 63.4% [95% CI: 61.9, 64.8], 32% [95%CI: 30.5, 33.4] and
4.7% [95% CI: 4.0, 5.3] in non-diabetic subjects. Being male was nearly 1.4 times likely to have loop
type (AOR= 1.385 95%CI 1.120, 1.714) and whorl type (AOR=1.359 95%CI 1.090, 1.696) than arch
type of dermatoglyphics patterns. Normal type of palmar crease has nearly similar distribution between
diabetic and non-diabetic subjects. From aberrant creases simian had a bit higher distribution in diabetics
compared to non-diabetics study participants.
Conclusion: The study showed that there was significant difference in the distribution of fingerprint
patterns between the diabetics and the non-diabetic subjects. The findings in the palm showed that normal
crease was the most frequent creases. In addition, there was significant association with sex, body side
and symmetryness in the pattern of fingerprint distribution between the diabetics and non-diabetic
subjects.
