Thigh Circumference and Overall Mortality

 

The relationship between thigh circumference and mortality of interest. The association of thigh circumference with all-cause mortality...shown after controlling for age, gender, body mass index, waist circumference, moderate activity, total cholesterol, anti-diabetic drugs, estimated glomerular filtration rate, smoking status, race, baseline cancer, diabetes, hypertension, and cardiovascular diseases. The solid lines represented the hazard ratios of thigh circumference and the shadowed area represented the corresponding 95% confidence intervals  Source

The average thigh circumference was 52 cm or approximately 20.4". Increasing the thigh circumference by 10% (2") reduced the all-causes Hazard Ratio by approximately 15%.

Correlation does not prove causality but this is interesting. Increased muscle-mass is proven to smooth out blood-sugar spikes. In general, physical fitness is related to better cardio-vascular health and reduced risk of falling.
