RT - Journal Article T1 - Relationship between 2D:4D digit ratio with waist to hip ratio, muscle mass and strength in postmenopausal women JF - KAUMS YR - 2017 JO - KAUMS VO - 20 IS - 6 UR - http://feyz.kaums.ac.ir/article-1-3229-en.html SP - 557 EP - 565 K1 - Digit (2D:4D) ratio K1 - Postmenopausal women K1 - Muscle strength K1 - Muscle mass K1 - Sarcopenia AB - Background: 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. Materials and Methods: 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. Results: 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<0.001). In addition, a weak negative correlation between the (2D:4D digit ratio and calf-circumference and skeletal muscle mass index (r=-0.21, P=0.008; r=-0.32, P=0.001, respectively) was observed, but there was no significant correlation between WHR and digit ratio (r=-0.14, P=0.08). Moreover, regression analysis showed that the 2D:4D digit ratio is a more predictive power for handgrip strength and quadriceps muscle strength (R2=0.38, R2=0.26, P<0.001, respectively). Conclusion: 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. LA eng UL http://feyz.kaums.ac.ir/article-1-3229-en.html M3 ER -
