Another risk factor could be race. Lighter skinned people, such as Caucasians and Asians, are more likely to develop osteoporosis than darker skinned people, African-American population or Hispanics. Another important risk factor is the family history. There is a genetic component to how much bone we have. If an individual's mother, aunt, grandmother has a history of osteoporotic fracture, they are at greater risk.
Excessive alcohol is also a risk factor.
Sedentary existence, no weight bearing activity or exercise will increase one's risk. And then there are some nutritional factors, inadequate calcium is an obvious one. Then physical characteristics, such as being small boned and thin, place patients at greater risk. The other question that we may have is that there are certain medications and diseases that place a patient at risk for osteoporosis. And that includes the medicine steroids that might be taken for asthma or arthritis, and any chronic disease such as diabetes and rheumatoid arthritis might place the patient at greater risk.
