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.
