current higher incidence of osteoporosis, it is not only a medical problem is a serious public health problem, recognized as the silent epidemic. With the advent of an aging society, the situation will become more acute. Therefore, attaches great importance to prevention and treatment of osteoporosis, don’t let osteoporosis caused diseases in human pandemic and disaster.
, Beijing Heng experts cover: incidence of osteoporosis in
osteoporosis fractures most common site for vertebral, hip and wrist, almost everywhere in the body of the bone may occur. In the United States, Europe and Japan a total of 7 patients with osteoporosis. According to the 1900 population census of 40 ~90 years old crowd, one per 10 years age group, the prevalence of osteoporosis, respectively, 18.2%, 54.8%, and 67.5%, osteoporosis in China is not only a medical problem, is a serious public health problem.
, Beijing Heng an expert about the second: etiology and risk factors of osteoporosis
the etiology of the disease was still not clear. Bone growth and development process, due to different rate of bone turnover and bone mass is not the same at different ages. Bone formation in childhood than bone resorption, bone mass continues to increase, continued until about 35 years old, the bone mass reached the highest value, called peak bone mass (90% 20 years ago to accumulation of 10% before the 21~30sui accumulation). Samoan women since the age of 40, after the men from the age of 50, bone resorption than bone formation and bone mineral and matrix have reduced bone mass tends to decline. Osteoporosis incidence of growth increases with age. Osteoporosis in women more than men, ages appear early, and bone loss has been very fast. This disease generally considers the following factors.
1 endocrine factors; estrogen deficiency, osteoporosis occurs in postmenopausal women is particularly high, premature ovarian failure osteoporosis occurs in advance, indicating the reduction of estrogen is an important risk factors. Menopause Hou to female hormone reduced mainly, old degradation followed by; parathyroid pigment, most scholars reported blood parathyroid pigment concentration with age increased and increased, due to elderly renal function physiological sexual decline, blood calcium value reduced, to stimulus parathyroid pigment secretion, on menopause Hou bone loose women of parathyroid function research results, is function low, and normal and with hyperthyroidism three who are has; drop calcium pigment, has research display all age group female of blood drop calcium pigment level more male for low, menopause group women of blood drop calcium pigment value than menopause Qian women for low, Therefore of the view that reduce serum calcitonin may be one reason why female susceptibility to osteoporosis; also of osteoporosis-related hormones, along with glucocorticoid, such as thyroid hormone, prolactin and growth hormone.
2 genetic factors; osteoporosis found in Caucasians,. followed by yellow, and black patients at least. Main indicators of bone mineral density in diagnosis of osteoporosis, BMD value primarily determined by genetic factors, followed by the impact of environmental factors. Recent research indicates that vitamin d receptor gene and bone mineral density of polymorphism are closely associated.
3 nutrition
lack of calcium, have found green youth, calcium intake and bone mass in adulthood directly related to the peak. According to reported low calcium diet (10 mg/kg/d weight) who has three-fourths suffers from bone loose, and high calcium diet (10 mg/kg/d weight) who only has one-fourth suffers from bone loose; long-term protein nutrition lack, caused plasma protein reduced, bone matrix protein synthesis insufficient, new bone generated backward, as while has calcium lack, bone loose is will speed up appeared; vitamin c lack, vitamin c is bone matrix hydroxyl breast ammonia acid synthesis not missing of, as lack is may makes bone matrix synthesis reduced.
4 waste
effects of muscle to the bone tissue is a mechanical force, muscular skeletal stout, high bone density. Activities for the elderly less muscle strength weakened, less mechanical stimulation, osteopenia. At the same time weakening of muscle strength and coordination disorders make it easier for the elderly fell, when associated with low bone mass are prone to fracture.
5 other factors
too much alcohol, cigarettes, coffee and caffeine intake is a risk factor for this disease. Alcohol poisoning complicated with cirrhosis will affect the liver, thereby affecting calcium absorption, alcohol also have a direct effect on osteoblasts, inhibits bone formation. Caffeine ingestion of excessive urinary calcium loss of calcium and endogenous manure. Smoking can also cause bone loss, the mechanism is still unknown
