The objectives of this study were to (1) obtain both femoral neck strength (FNS) and @entity572 ( @entity572 ) values from left and right femurs (regardless of hip dominance) measured by DXA and evaluate their relationship with @entity1555 of all hip regions including total hip, (2) determine if there is a difference between dominant and nondominant hip @entity1555 in any of the hip regions, and (3) determine how physical activity influences hip @entity1555 . @entity1 were 136, generally healthy Caucasian @entity1 (57.4-88.6 years). @entity1555 was measured by DPX- @entity601 . Past and present activity was assessed by the Allied Dunbar National Fitness Survey for older adults and normal/brisk walking pace was measured in a straight hallway. FNS analysis uses femoral geometry to calculate stresses at the femoral neck for two loading conditions: Safety Factor Index (SF) indicates risk of @entity174 for forces generated during a one-legged stance, and Fall Index (FI) indicates risk of @entity174 for forces generated during a fall on the greater trochanter. Simple and multiple regression analyses were used to determine predictive ability of @entity572 , SF, and FI for respective hip @entity1555 values. There was no statistical difference in @entity1555 between two hips in any of the measured regions, however, the nondominant hip correlated better with other skeletal sites. Subjects with a faster normal walking speed had higher neck @entity1555 in the nondominant hip, 0.832 +/- 0.12 vs. 0.791 +/- 0.10 g/cm2 (P < 0.05). Longer @entity572 of the left hip was negatively related to neck, trochanter, shaft, and total hip @entity1555 . FI was significantly associated with all sites of the hip @entity1555 , while SF was associated only with neck and wards BMC (P < 0.05). In summary: (1) a longer @entity572 is associated with lower @entity1555 and a higher FI with higher @entity1555 , (2) it might be sufficient to measure @entity1555 in only the nondominant hip, and (3) walking at a faster pace may positively benefit femoral neck @entity1555 . Therefore, it appears that @entity572 , SF, and FI all play important roles in estimating @entity174 risk and should be assessed along with @entity1555 when using DXA.
