title: Maintenance of bone density: outcomes over five years of attendance at an osteoporosis center.
abstract: BACKGROUND
  This is a longitudinal analysis of the data from women who visited the Osteoporosis Prevention Center for at least five years. The study is part of an ongoing evaluation of the results of the Center visits.
  
  
  METHODS
  A random sample of 100 women who had attended the clinic for more than five years and were not referred for a definite medical diagnosis was pulled from the records. Descriptive statistics were compiled on this sample. Seventy-five women were postmenopausal and over 49 years of age. This subgroup was studied for change in bone mineral density (BMD) over the five years.
  
  
  RESULTS
  The BMD change was 0.03 gm/cm2 in the spine, -0.01 gm/cm2 in the femoral-neck. and -0.008 gm/cm2 at the radius over the five years.
  
  
  CONCLUSIONS
  Attendance at the Osteoporosis Prevention Center was associated with maintenance of bone density in the spine over a five-year period.
