Abstract

Background The length of the second digit (the index finger) relative to the length of the fourth digit (the ring finger) is sexually dimorphic as males have a lower second to fourth digit ratio (2D:4D). There is evidence that sex differences in 2D:4D arise from in utero concentrations of sex steroids, with a low 2D:4D (male typical ratio) being positively related to prenatal testosterone, while a high 2D:4D (female typical ratio) is positively associated with prenatal oestrogen Objective To investigate possible associations between 2D:4D ratio and sexually dimorphic body composition Methods 2D:4D ratio, body mass index (BMI), waist circumference, waist-hip ratio (WHR), weight, and body fat percentage was measured from 46 men and 20 women Results Digit ratio was found to be significantly lower in men than in women. No significant correlation between 2D:4D ratio and body compositions was found for both men and women while digit ratio in obese men was significantly higher than normal weight men. Conclusion This finding dose not support the significant correlation between digit ratio and sexually dimorphic body composition. However digit ratio in obese men was significantly higher than normal weight men.
