Objective: To study the effect of the nutritional education and dietary intervention on nutritional status and bone mineral density (BMD) of middle-aged and senile patients with osteoporosis.
Methods: Ninty middle-aged and senile osteoporosis patients were enrolled. They were randomly divided into two groups (intervention and control group) with 45 cases each. The control group was received conventional therapy and the intervention group added with nutritional education and dietary intervention for six months on the basis of conventional therapy. The methods of education and intervention included seminars, brochures distribution, dietary survey and individual guidance. The nutritional status and BMD were analyzed at the beginning and the end of the intervention respectively.
Results: After the intervention, the ratios of subjects whose intake of grain, vegetables, fruits, eggs, milk and beans in line with recommended intake of the intervention group were higher than those of the control group (P < 0.05). After the intervention, frequencies of coarse grain, dairy, beans and seafood consumption of the intervention group were higher than those of the control group (P < 0.05). After the intervention, the daily intakes of protein, VA, VC, calcium, zinc, magnesium, dietary fiber of the intervention group were significantly superior to the control group (P < 0.05). BMDs of lumbar spine and femoral neck in the intervention group were significantly higher than those in the control group (P < 0.05).
Conclusion: The nutritional education and dietary intervention could promote middle-aged and senile patients' reasonable diet, improve their nutritional status, enhance bone mineral density and improve the effect of conventional therapy for osteoporosis.
