title: Non-sedentary Lifestyle Can Reduce Hip Fracture Risk among Older Caucasians Adults: The Adventist Health Study-2.
abstract: OBJECTIVE
  The beneficial effect of physical activity on reducing hip fracture risk has been supported in many previous studies. The present cohort study explores the relationship between total daily physical activity expressed as MET-hour/day and hip fracture risk among men over 50 years of age and postmenopausal women (n=22,836).
  
  
  METHODS
  Associations between self-reported hip fracture incidence and total daily physical activity and selected lifestyle factors were assessed using Cox proportional hazard regression.
  
  
  RESULTS
  In gender-specific multivariable models, total activity above average (≥ 51 MET-hours per day for men, ≥ 48 MET-hours per day for women) compared to those with sedentary lifestyle (< 40 MET-hours per day) reduced the risk of hip fracture by 60% among men (HR=0.40, 95%CI: 0.23-0.70) (Ptrend=0.002) and 48% among women (HR=0.52, 95%CI: 0.32-0.84) (Ptrend=0.01).
  
  
  CONCLUSIONS
  Our findings suggest that a moderate level of physical activity and avoiding a sedentary lifestyle can reduce the risk of hip fracture among the elderly.
