Relationships Between Calcium Intake and Proper Exercise and Bone Loss: A 5-Year Study

Relationships Between Calcium Intake and Proper Exercise and Bone Loss: A 5-Year Study

The bone density of os calcis were measured with ultrasonic bone densitometry in 6, 680 healthy rural women in Mie Prefecture. Serum BGP and B-ALP levels were measured in 350 and 450 randomly selected cases respectively. The relations between their titers and bone loss with advancing age were also a...

description The bone density of os calcis were measured with ultrasonic bone densitometry in 6, 680 healthy rural women in Mie Prefecture. Serum BGP and B-ALP levels were measured in 350 and 450 randomly selected cases respectively. The relations between their titers and bone loss with advancing age were also assessed. The BGP and B-ALP values began to rise in those subjects aged around 45 years. The elevated levels seemed to be kept till they became 70 years old. In this period, they might have massive bone loss with a high bone turnover, if they did not have an adequate calcium intake and exercise. During this longitudinal observation, we measured bone density in 795 women 1, 062 times over a period of five years, with the initial bone mass value set at 100% and all the subsequent values expressed as a percentage of the initial value. Its value increased for about 106% and decreased from 95 to 91% in five years. By age, its numbers increased for 30% to 40% for those in their 40s and 60s, respectively. Overall, the decreases were significant (p
