Osteopenia

A 55-year-old asymptomatic woman, who is 5 years postmenopausal, is concerned about osteoporosis, since her mother had a hip fracture at the age of 70 years. The patient has no personal history of fractures and has never taken corticosteroids. She does not smoke but does drink one to two glasses of wine a day. Her weight is 105 lb (48 kg), and her height is 62 in. (1.6 m); she has a body-mass index (the weight in kilograms divided by the square of the height in meters) of 19.2. Measurements of bone mineral density with the use of dual-energy x-ray absorptiometry show T scores of -1.7 at the spine and -1.5 at the femoral neck, findings that are consistent with osteopenia. What should you advise?
