Primary Outcome Measures:
  • Bone Density of the hip

Secondary Outcome Measures:
  • Annual and Seasonal patterns of change in bone mineral density of the hip
  • Associations between biochemical, physical and life-style factors
  • Examine influence of clinical status, lifestyle, medication use and season on the occurrence of falls

Estimated Enrollment: 450
Study Start Date: October 1992
Estimated Study Completion Date: February 1996
Detailed Description:

In this study 445 men and women age 65 and older were enrolled for three years each. Subjects were randomized to treatment with 500 mg of calcium s calcium citrate malate plus 700 IU of vitamin D daily or placebo. Subjects came to the research center every six months for biochemical and bone mineral density measurements. Changes in these measures over the three years were determined in each group and compared.
