NEW YORK — The size of a man’s biceps and his waist could provide a more accurate picture of his mortality risk than body mass index alone, according to British researchers.
A study of 4,107 men aged 60 to 79 found those with a waist of less than 102 centimeters and above-average muscle mass in their upper arms were the least likely to die over a six-year period, according to Dr. S. Goya Wannamethee of Royal Free and University College Medical School in London.
