In anthropological assessments, pelvic indices are used as additional measurements. Computed tomography (CT) is used to examine modern human variation and extending osteological assessment resources to researchers, which provides more quantitative data. This study aims to obtain data on age distribution of adults who were performed 3D CT pelvis and radiometric variables in pelvic anthropometry studies. Methods: This study used observational analytical design with cross-sectional approach. Population of study was all patients in Radiology Installation of Dr. Soetomo General Hospital, Surabaya, Indonesia who underwent pelvic 3D CT examination from September to December 2019. Radiologic component and demographic data were collected and statistically analyzed. Results: There were 204 samples included, where it was found that the patients? mean age was 50.23 ? 14.36 years. All radiologic components were also significantly different between sexes (p<0.05), except for transverse diameter of sacral segment (p=0.180). Conclusion: There were differences in age distribution of adults undergoing pelvic 3D CT as well as radiometric variables in pelvic anthropometric studies. Multicentric studies are needed to obtain a greater variety of data and produce more accurate data and formulas.
