title: Associations between frequency of coffee consumption and osteoporosis in Chinese postmenopausal women.
abstract: BACKGROUND
  This study was aimed at estimating the associations between coffee intake and osteoporosis (OP) in Chinese postmenopausal women.
  
  
  METHODS
  We conducted a large-scale, community-based, cross-sectional study to investigate the associations by using self-report questionnaire to access frequency of coffee intake. The total of 1817 participants was available to data analysis in this study. Multiple regression models controlling for confounding factors to include frequency of coffee intake variable were performed to investigate the relationships for OP.
  
  
  RESULTS
  Positive correlations between frequency of meat food intake and T-score were reported (β = 0.216, P value < 0.001). Multiple regression analysis indicated that the frequency of meat food intake was significantly associated with OP (P < 0.05 for model 1 and model 2). The postmenopausal women with high frequency of meat food intake had a lower prevalence of OP.
  
  
  CONCLUSIONS
  The findings indicated that frequency of coffee intake was independently and significantly associated with OP. The prevalence of OP was more frequent in Chinese postmenopausal women not preferring coffee habits.
