Abstract:
Objective To observe influence of basic osteoporosis intervention on the 25-hydroxy vitamin D[25(OH)D] levels,low limb muscle strength and its balance function among Chinese elderly people.Methods Cross sectional study and statistics analysis were performed among total 1026 elderly (≥65years) patients from 16 hospitals throughout China.Daily taking amount of dairy products,calcium,vitamin D supplement,sunlight and physical exercise were recorded.Serum 25 (OH) D level was measured.Limb muscle strength and balance tests were performed.Results Daily intake of dairy products was insufficient in more than 42.0％ (430 cases) participating patients.The average sunlight time of participating patients was (1.2 ± 0.8) h per day.The average physical exercise time was (1.2 ± 0.7) h per day.37.7 ％ (387 cases) participating patients took supplemental calcium and vitamin D.36.8％ (278 cases)participating patients took supplemental calcium.The 25 (OH) D level was less than 50 nmol/L in 77.2％ (792 cases) participating patients,while 50～75 nmol/Lin 16.7％(171 cases).48.7％ (474/973),64.6％(624/966)and 63.6％ (614/966) patients were in high fall risk according to the timed up and go test(TUG),chair rising test(CRT) and tandem gait test(TGT),which showed that the levels of 25 (OH) D deficiency were positively correlated with the elderly fall risk.Conclusions Daily intake of dairy products,sunlight,calcium and ordinary vitamin D supplement are insufficient among Chinese elderly people.Decreases of muscle strength and balance function among elderly people are related to 25 (OH) D levels.Exercise,not Vitamin D supplement,can reduce fall risk through improving muscle strength and balance function in elderly people.
