Objective : To study the risk factors associated of femoral neck and intertrochanteric fractures in Thai women
Material and Method: A case-control study was conducted in Bangkok and its vicinity between 1997 and
1998 to compare factors related to each type of hip fracture in Thai women. Cases, aged > 51 years old, were
diagnosed as intertrochanteric or femoral neck fracture and were matched with controls by age and sex.
Multinomial logistic regression was performed for significant associated factors.
Results : Recent physical activity and steroid-containing traditional medicine were strongly associated with
intertrochanteric fractures (adjusted odds ratio (OR) 0.17 (95% CI: 0.07, 0.42) and 6.50 (95% CI: 1.93,21.82),
respectively) when compared to femoral neck fractures. Cerebrovascular accident (CVA) was more related to
femoral neck fractures when compared to intertrochanteric fractures (adjusted OR 8.63 (95% CI: 2.28,32.66),
and 4.79 (95% CI: 1.19,19.29), respectively).
Conclusion : Intertrochanteric fracture could be minimized more by encouraging physical activities and
avoidance of steroid use while the reduction of femoral neck fracture should be achieved more by CVA
prevention.
