Relationship between 2D:4D digit ratio with waist to hip ratio, muscle mass and strength in postmenopausal women

In previous studies the ratio between 2D:4D hand digits was proposed as an indicator of testosterone level and can be related to aging-induced sarcopenia. Based on the notion, the aim of present study was to investigate the relationship between (2D:4D digit ratio and waist to hip ratio (WHR), muscle mass and strength in postmenopausal women.
One-hundred forty eight postmenopausal women (average age: 53.74±4.38 years) were selected purposefully. Anthropometric characteristics of subjects, skeletal muscle mass index, handgrip strength and quadriceps strength were measured.
The results showed a significant negative correlation for 2D:4D digit ratio with handgrip strength and quadriceps muscle strength (r=-0.62, r=-0.51 and P Among the postmenopausal women the 2D: 4D digit ratio has a stronger correlation with handgrip strength and quadriceps muscle strength than the other variables. This finding can be used to check the possibility of reduced muscle strength in postmenopausal women.
