| Popis: | Background:. The second-to-fourth digit ratio is measured by dividing the length of the index finger by the length of the ring finger. A ratio 1 means that the index finger is longer; this is known as the female pattern or “C” pattern. When both fingers are equal in length (ratio = 1), the pattern is labeled as “B” pattern; this may be seen in both sexes. None of the previously reported studies on this topic were reported in the plastic or hand surgery literature. Our aim is to increase the awareness of plastic and hand surgeons to these types of hand patterns and to correlate such patterns to sex, body mass index (BMI), and physical activity in a group of healthy medical students and interns. Methods:. We conducted a cross-sectional study on 160 healthy medical students/interns. There were 82 females and 78 males between the ages of 20 and 30. A male pattern (pattern A) was defined as pattern A in both hands or pattern A in one hand and pattern B in the other hand. A female pattern (pattern C) was defined as pattern C in both hands or pattern C in one hand and pattern B in the other hand. The correlation between hand pattern and sex, BMI, and physical activity was done using the chi-square test and Fisher’s exact test. A P value of |
