光照时长对老年性骨质疏松疗效的临床观察

The clinical observation of the efficacy of sunshine on senile osteoporosis

目的探讨接受光照的时长对老年人骨质疏松的影响。方法按试验设计选取120例骨质疏松患者,分为实验1组、实验2组和对照组。3组患者禁烟酒,合理膳食(摄入富含钙、磷、蛋白质的膳食、水果),对照组每日(阴雨天除外)接受晨起8点到9点日照1 h,配合阿伦膦酸盐70 mg口服,每周1次,连续8个月。试验1组和试验2组在对照组基础上分别每日接受晨起光照2 h和3 h,连续8个月。观察内容主要是骨密度值的变化情况及疼痛的缓解程度。结果实验1组与对照组差异有显著性意义(P<0.05),实验2组与实验1组差异无显著性意义(P>0.05)。结论 2 h光照对骨质疏松症的治疗效果优于1h光照,且效果最为明显,光照3 h及以上对骨质疏松治疗效果与2 h无明显差异。

Objective To explore the effect of the time of sunshine on osteoporosis in the elderly. Methods According to the experimental design 120 patients with osteoporosis were selected. They were divided into the experiment group 1, group 2, and the control group. The patients in 3 groups abstained from smoking and wine and had rational dietary intake （rich in calcium, phosphorus, protein, and fruits）. Patients in control group had 1-hour sunlight from 8 to 9 am daily （except in rainy days） , and received 70 mg alendronate once a week for 8 months. Patients in experiment group 1 and group 2 received 2 hours or 3 hours morning light a day, respectively, on the basis of control group. The change of bone mineral density and the degree of pain were observed. Results The difference between experiment group 1 and the control group was significant （ P 〈 0. 05 ）. The difference between the experiment group 2 and experiment group 1 was not significant （ P 〉 0. 05 ）. Conclusion The effect of 2-hour illumination is better than that of 1-hour for osteoporosis patients. The effect of 3-hour and more sunlight is not better than that of 2- hour for osteoporosis treatment.
