[Survey and analysis of incidence and relevant factors of osteoporosis in the elderly (with a report of 2041 cases)].
This paper reports the results of roentgenography of calcaneum in 2,041 persons without any underlying disease causing osteoporosis. The trabecular patterns of calcaneum were divided into 5 grades according to Jhamaria method. The incidence of osteoporosis is 18.18%, 25.96%, 54.80%, 67.33%, 85.45% and 90% and the average grading of calcaneum were 2.98, 2.96, 2.53, 2.11 and 2.14 in male and 3.50, 2.89, 2.50, 2.06, 1.60 and 1.61 in female in these aged groups respectively Serum Ca, P, Mg and Vitamin D were determined in 1,798 persons over 60 years of age. There is no significant difference among them Bone density was determined in 381 cases, showing 0.507 +/- 0.003, 0.598 +/- 0.095, 0.673 +/- 0.052, and 0.0645 +/- 0.095 among Jhamaria grading index I, II, III, IV. There is significant difference between 1-2 and 3-4 grading index, suggesting Jhamaria method gives a reliable, simple and applicable criterion for diagnosis of osteoporosis. The relevant factors influencing osteoporosis are discussed.
