Mid-arm circumference

1. Functional foods and nutraceuticals increase mid-arm circumference in humans (+2.2%).

   “Mid-arm circumference increased significantly by 2.2% (p = 0.02), while triceps skinfold thickness decreased by 11% (p = 0.02), suggesting increased muscle mass and reduced subcutaneous fat.”

1. Mid-arm circumference predicts sarcopenia in humans (AUC 0.85 (95% CI 0.83-0.86)).

   “their AUCs could be ordered as MAC (0.85, 95% CI 0.83-0.86) > GNRI (0.80, 95% CI 0.78-0.82)”

2. Mid-arm circumference raises the risk of sarcopenia in humans (OR 4.24 (95% CI 3.56-5.05, P < 0.001)).

   “MAC, TST and BMI per standard deviation decrease were 2.95 (95% CI 2.51-3.47, P < 0.001), 1.01 (95% CI 0.90-1.15, P = 0.816), 4.56 (95% CI 3.82-5.44, P < 0.001), 4.24 (95% CI 3.56-5.05, P < 0.001)”

1. Mid-arm circumference is associated with episodic memory score in humans (PB < 0.0125).

   “Higher MAC (or MAC/WC) significantly correlated with better EMS”
