The participants in the present study were 130 elderly women living in Khon Kaen, Thailand. All except one subject was undergone by both DEXA-BMD and AP radiographs of the left hip joints. The mean (SD) of age, weight, height and BMI of the 129 participants were 72.5 (5.3) years old, 49.8 (10.3) kg, 1.49 (0.06) m, and 22.21 (4.13) kg/m2, respectively. Poor intrapersonal reliability (kappa = 0.11 and 0.11) and poor interpersonal reliability (kappa = 0.15) for the modified Singh index with three grades were found. On the other hand the modified Singh index with two grades had high accuracy in diagnosing of femoral neck and total hip osteoporosis (0.74 and 0.81 respectively) when comparing with DEXA-BMD.
