(HealthDay News) -- Although osteoporosis is more common in postmenopausal women, men are also vulnerable to thinning bones as they age.

The American Academy of Orthopaedic Surgeons says risk factors for osteoporosis in men include:

• Drinking excessive amounts of alcohol or using tobacco.
• Not exercising regularly.
• Having a low body-mass index.
• Getting insufficient vitamin D and calcium.
• Taking certain medications, including anticonvulsants, oral glucocorticoids or heparin.
• Getting older.
• Having a family history of fractures related to fragile bones.
• Certain health conditions, including asthma, thyroid disorders or rheumatoid arthritis.
• Having low levels of certain hormones, including testosterone or estrogen.
