title: [Relationship between bone mineral density and blood and urine biochemical indices in women].
abstract: OBJECTIVE
  To study the relationship between bone mineral density (BMD) and some biochemical indices in their blood and urine of women.
  
  
  METHODS
  Fasting urinary calcium (Ca) and creatinine (Cr), ratio of Ca to Cr, urinary hydroxyproline (Hyp), ratio of Hypr to Cr were determined in 163 healthy women, and activity of serum alkaline phosphatase (AKP) were determined in 182 healthy women. BMD at the 1/10 lower end and 1/3 middle-lower site of the radius were measured with single photon absorptiometry for all of them.
  
  
  RESULTS
  Serum AKP and ratio of urinary Hyp/Cr increased with age, especially postmenopause, and correlated negatively with BMD. Fasting urinary Ca/Cr ratio also increased with age, especially postmanopause, but not correlated with BMD.
  
  
  CONCLUSIONS
  Serum AKP and fasting urine Hyp/Cr ratio could be used as indicators to reflect bone remodeling and absorption, respectively.
