Osteopenia is defined as the stage of low bone density that precedes osteoporosis. At this stage, bone density is below average but not as low as occurs with osteoporosis. The World Health Organization formed a committee in 1994 to define osteoporosis, and four categories were defined: normal, osteopenia, osteoporosis, and established osteoporosis. All of these categories are measured by bone density and the prevalence of fractures. In osteopenia,
According to the National Osteoporosis Foundation, approximately 10 million women and 2 million men in the United States have osteoporosis. Men have bones that are much larger and stronger than women's bones, which is why women suffer from the condition more often than men. However, both men and women share similar risk factors for osteoporosis (e.g., prolonged exposure to certain medications, chronic diseases that affect vital organs, undiagnosed low levels of testosterone, lifestyle habits, age, heredity, race), so methods of intervention are similar.
