Osteoporosis is characterized by a reduction in bone mineral density (BMD). Dietary patterns that encourage adequate calcium intake are essential to maximal development and later maintenance of bone mass. The majority of white women are at risk for osteoporosis-related fractures, especially in the wrist, spine, and hip. The degree of fracture risk at a specific bone site is best assessed by measuring BMD with single- or x-ray-photon absorptiometry. BMD in adults of any age is quite variable. Numerous diet and lifestyle factors influence BMD and, in turn, fracture risk. Sufficient evidence exists for a relationship between BMD and diet, particularly calcium and vitamin D; amenorrhea; body weight; alcoholism; smoking; and physical inactivity. Less convincing evidence exists for a relationship with dietary protein, dietary phosphorus, and caffeine intake. To minimize fracture risk, young women should have regular menses, consume a nutritionally adequate diet (according to the principles of the Food Guide Pyramid), perform regular physical activity, only consume a moderate intake of alcohol (if any), and not smoke. Postmenopausal women should follow those same guidelines and should seriously consider estrogen replacement therapy. Elderly persons especially should ensure adequate calcium and vitamin D nutriture. Currently, osteoporosis is the rule, rather than the exception, in old age for many white women. Dietitians can help reduce the prevalence of this disorder.

UI	MeSH Term	Description	Entries
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D010024	Osteoporosis	Reduction of bone mass without alteration in the composition of bone, leading to fractures. Primary osteoporosis can be of two major types: postmenopausal osteoporosis (OSTEOPOROSIS, POSTMENOPAUSAL) and age-related or senile osteoporosis.

D000368	Aged	A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available.	Elderly
D015444	Exercise	Physical activity which is usually regular and done with the intention of improving or maintaining PHYSICAL FITNESS or HEALTH. Contrast with PHYSICAL EXERTION which is concerned largely with the physiologic and metabolic response to energy expenditure.

D015519	Bone Density	The amount of mineral per square centimeter of BONE. This is the definition used in clinical practice. Actual bone density would be expressed in grams per milliliter. It is most frequently measured by X-RAY ABSORPTIOMETRY or TOMOGRAPHY, X RAY COMPUTED. Bone density is an important predictor for OSTEOPOROSIS.

D015663	Osteoporosis, Postmenopausal	Metabolic disorder associated with fractures of the femoral neck, vertebrae, and distal forearm. It occurs commonly in women within 15-20 years after menopause, and is caused by factors associated with menopause including estrogen deficiency.

D015914	Estrogen Replacement Therapy	The use of hormonal agents with estrogen-like activity in postmenopausal or other estrogen-deficient women to alleviate effects of hormone deficiency, such as vasomotor symptoms, DYSPAREUNIA, and progressive development of OSTEOPOROSIS. This may also include the use of progestational agents in combination therapy.
