title: Osteoporosis and related factors in older females with skeletal pain or numbness: a retrospective study in East China.
abstract: OBJECTIVE
  To analyse relationships between incidence of osteoporosis, age and clinical symptoms in older female patients in East China.
  
  
  METHODS
  Data from females aged ≥ 30 years, admitted to QiLu Hospital between January 1999 and December 2011 were retrospectively assessed for osteoporosis. Correlations between osteoporosis diagnosis, age and clinical symptoms were analysed. Factors associated with osteoporosis were assessed using logistic regression.
  
  
  RESULTS
  Out of 4212 patients enrolled, 1673 were assigned to the osteoporosis group and 2539 to the nonosteoporosis group. Neck, shoulder and arm pain negatively correlated with osteoporosis diagnosis. Lumbar and back pain had no correlation with osteoporosis diagnosis. In patients with osteoporosis there was no relationship between bone density and site of clinical symptoms. Bone density decreased, as age increased, in patients aged >50 years in the osteoporosis group.
  
  
  CONCLUSIONS
  The present study revealed a relationship between epidemiological distribution of osteoporosis and associated factors in adult females suffering from pain or numbness, in East China.
