title: [Usefulness of a clinical questionnaire for screening osteopenia and osteoporosis in post-menopausal women].
abstract: BACKGROUND
  The prevalence of osteoporosis in post-menopausal women (PMW) is 30 %, and bone densitometry (BD) is the gold standard. This is not recommended as a screening test because of its cost. Instead, the SCORE index (Simple Calculated Osteoporosis Risk Estimation) is proposed. The objective is to determine the sensitivity and specificity of this test in the population and the optimization of BD.
  
  
  METHODS
  The SCORE Index is a pre-screening questionnaire; it was used in PMW to compare with BD, registering the total score of the questionnaire, densitometry diagnosis, the fracture risk and the site of osteoporosis. The sensitivity and specificity of SCORE Index and chi(2) of Mantel-Hanszel were calculated.
  
  
  RESULTS
  We studied 201 patients, mean age 55.70 years. Osteoporosis was recognized in 22.8 %, osteopenia in 68.3 % and 8.9 % was normal. The sensitivity of the SCORE index was 87 % (95 % CI = 77-97) and specificity was 34.6 % (95 % CI = 27-42) with p = 0.000. A positive probability quotient of 1.33 (95 % CI = 1.1-1.7).
  
  
  CONCLUSIONS
  Osteoporosis is a frequent disease in PMW. It is mandatory to have cheap and easy-tools which can detect osteoporosis cases.
