title: [Effects of aging and decreased glomerular filtration rate on the prevalence of anemia in elderly population receiving body check from urban area of Hefei, China.].
abstract: OBJECTIVE
  To investigate the effects of aging and the decreased glomerular filtration rate on the prevalence of anemia in elder receiving body check from urban area of Hefei, China.
  
  
  METHODS
  A total of 4547 > 60 years subjects received healthy examination in Healthy Center of Anhui Provincial Hospital from January 2005 to December 2007 were enrolled in this study. Anemia was defined as hemoglobin < 120 g/L in men or < 110 g/L in women.
  
  
  RESULTS
  The prevalence of anemia in the subjects was 4.40% (95%CI: 3.83% - 5.05%) and significantly increased with the aging process and the decline of estimated glomerular filtration rate (eGFR). With logistic analyses, increasing age, female, decreased eGFR were major risk factors for anemia.
  
  
  CONCLUSIONS
  The morbidity of anemia is 4.40% in old population receiving body check from urban area of Hefei, China. Aging and the decline of eGFR are the independent risk factors of anemia.
