Abstract:
Objective To survey a prevalence of osteoporosis and prevalence of osteoporosis combined with hyponatremia in elderly hospitalized patients,and their risk factors.Methods We enrolled 2496 elderly hospitalized patients with detected plasma levels of sodium,calcium,25 (OH) D3,PTH,plasma PINP,and β-CTX.At the same time,sex,age,height,weight,smoking history,drinking history and BMI(kg/m2) in form of a questionnaire were recorded and calculated.The risk factors for osteoporosis were analyzed using multivariate Logistic regression method.Results The osteoporosis prevalence was 12.2％ (305/2496 inpatients)with 31.5 ％ (96/305)in male,68.5％ (209/305)in female(x2 =4.651,P=0.031).The prevalence of osteoporosis with hyponatremia was 27.5 ％ (84/305),with 24.8 ％ (21/84) in male and 75.2 ％ (63/84) in female(x2 =9.251,P=0.025).As compared with three groups of non-osteoporosis,normal serum Na+ with and without osteoporosis,the osteoporosis patients with hyponatremia were more aged,in a higher proportion of women and smokers,in lower BMI,and in low levels of serum sodium,BMD 25(OH)D3 (F=13.783,0.861,7.146,24.520,0.548,x2 =15.113、4.472;P =0.001,0.000,0.021,0.015,0.003,0.021,0.005).Multivariate Logistic regression analysis showed that aging,female,low BMI,smoking history,drinking history,low plasma 25(OH)D3 level,low plasma PINP level,and high plasma β-CTX level were the risk factors for osteoporosis(OR 4.215,2.271,3.176,2.013,1.237,3.987,1.843,1.972;all P＜0.05).Conclusions The osteoporosis prevalence is high in elderly patients,especially in old women.The risk factors for osteoporosis are diverse,and clinical conditions of osteoporosis patients with hyponatremia are much more severe than the others.More efforts should be given to them and need to be focused on the complications of osteoporosis.
