Kim BJ, et al. - Data gathered from a nationally representative cohort demonstrate that higher dietary protein intake was positively associated with the composite indices of femoral neck (FN) strength in both men and women, suggesting that higher protein intake may contribute to lower risk of hip fracture through the improvement of bone strength. In this current investigation, it was demonstrated that total protein intake positively correlated with all three FN composite indices [compression strength index (CSI), bending strength index (BSI), and impact strength index (ISI)] in both genders, except for BSI showing marginal significance in postmenopausal women. These findings offered the clinical evidence that through the increase of FN strength relative to load in adults, higher dietary protein intake could play a beneficial role in bone health.
