title: Association of osteoporotic fracture with smoking, alcohol consumption, tea consumption and exercise among Chinese nonagenarians/centenarians.
abstract: OBJECTIVE
  To observe the association of osteoporotic fracture with habits of smoking, alcohol consumption, tea consumption and exercise among very old people.
  
  
  METHODS
  A cross-sectional study conducted in Dujiangyan Sichuan China.
  
  
  METHODS
  703 unrelated Chinese nonagenarians and centenarians (67.76% women, mean age 93.48 years) resident in Dujiangyan.
  
  
  METHODS
  Medical history of osteoporosis and the statement of fracture and habits (current and former) of smoking, alcohol consumption, tea consumption and exercise were collected.
  
  
  RESULTS
  In women, subjects with current or former habit of alcohol consumption had significantly higher prevalence osteoporotic fracture than those without this habit; but subjects with former habit of exercise had significantly lower prevalence osteoporotic fracture than those without this habit. However, in men, there was no significant difference in prevalence of these habits between subjects with and without osteoporotic fracture. After adjust for age, gender, sleep habits educational levels, religion habits and temperament, we found that former habit of alcohol consumption had a significant odds ratio (OR=2.473 95% CI (1.074, 5.526)) for osteoporotic fracture.
  
  
  CONCLUSIONS
  In summary, among nonagenarians and centenarians, among habits (current and former) of smoking, alcohol consumption, tea consumption and exercise, there seems to be significant association of osteoporotic fracture only with current or former habits of alcohol consumption, former habit of exercise. The habit of alcohol consumption might be associated with a greater risk of osteoporotic fracture, but the former habit of exercise might be associated with a lower risk of osteoporotic fracture.
