AB  - We analyzed 2,107 hip dual-energy X-ray absorptiometry (DXA) images from the 
      Japanese Population-based Osteoporosis Study with the Hip Structure Analysis 
      (HSA) program to obtain age-specific reference values of HSA indices for the 
      Japanese female population. These references may help physicians accurately 
      assess HSA results and aid researchers in making interracial comparisons of the 
      indices. INTRODUCTION: Hip geometry is expected to improve hip fracture risk 
      assessment, which is usually assessed by bone mineral density (BMD) alone. We 
      aimed to establish a reference database for Japanese women. METHODS: We studied 
      2,107 Japanese women (15-79 years old) with no history of bone metabolism-related 
      diseases from the Japanese Population-based Osteoporosis Study performed in 1996. 
      Hip geometry was conducted on DXA images with the HSA program, which yielded data 
      for cross-sectional area (CSA), subperiosteal diameter (PD), endocortical 
      diameter (ED), mean cortical thickness (CT), section modulus (SM), and buckling 
      ratio at the narrow neck (NN), intertrochanter (IT), and femoral shaft (FS) 
      regions. Mean HSA indices were determined for each 5-year age group after 
      adjustment for height and weight based on most recent Japanese population values. 
      RESULTS: Age-related changes in HSA indices were evident for the 50-54 year group 
      in the NN and IT regions and for the 55-59 year group in the FS region; these 
      changes increased with age thereafter. Age-related changes in CSA and CT were 
      almost identical to that of BMD. Japanese subjects exhibited BMD and CT values 
      similar to those reported for US non-Hispanic white women, but had 16-23% smaller 
      SM values. CSA and CT were highly correlated with conventional BMD, whereas ED, 
      SM, and PD showed lower correlations. CONCLUSIONS: Age-specific reference values 
      of HSA indices for the Japanese female population were obtained. This database 
      will form the foundation for accurate HSA result evaluation.
