Not so. More than 2 million American men have been found to have the thinning bones and skeletal weakness of osteoporosis, and an additional 3 million are at an increased risk of developing them. Its true that osteoporosis strikes women with much greater frequency than men - in some studies as much as four to six times as often. But thats no reason to brush it off as their disease. Its a mere stroke of gender luck that mens bones tend to grow larger, stronger and denser. Also paying dividends are those spots that boys (and, increasingly, girls) play as children - running up and down basketball courts, soccer and baseball fields. As it happens, physical activity is one of the more important ways to increase bone density and protect bone health. But even the most active men cannot ignore certain facts of life. All of us build up our bones during the first three decades of life, typically reaching peak bone mass in the early 30s. Around the age of 35, we begin gradually to lose some of this bone mass. Women ultimately give up between 30%. Though mass loss in men is lower, it still makes us vulnerable to back pains and bone fractures. In fact, this year alone American men will suffer as many as half a million osteoporosis-related breaks, mostly in the spine, hip and wrist. These are not only painful; thousands die each year from fracture-related complications. |
