“…Applying the stature groupspecific formulae reduced the differences between actual and estimated heights in the short and tall subgroups. In previous studies, we compared stature group-specific formulae based on tibia length with a general formula, and found that the group-specific formulae gave more accurate height estimates Pelin and Duyar, 2003). Since the actual height of victims is generally unknown in forensic cases we focused on this problem in the present study.…”

In forensic and anthropological studies, body height is usually estimated from a single regression formula of the population of interest. The aim of this study was to test the accuracy of regression formulae devised for different stature groups (short, medium, tall) within the same population. Our study is based on 242 adult male subjects aged 18.1-44.6 years. Body height, tibia length, and ulna length were measured by standard anthropometric techniques. The subjects were randomly divided into a study group (Group 1, n = 121) and a cross-validation group (Group 2, n = 121). In the first stage of the study, general regression formulae based on ulna length, tibia length, and a multiple equation based on ulna and tibia lengths were created for Group 1, and these equations were tested using the data and actual heights of the Group 2 subjects. In the second stage of the study, stature group-specific formulae were constructed for the same variable(s) (ulna length, tibia length, and both of them). Since the body height of the victims is unknown in cases for which estimations need to be made, Group 2 was categorized according to long bone (ulna, tibia, and ulna + tibia) lengths, using the 15th and 85th percentiles as cut-off points. Each set of group-specific formulae were tested with the cross-validation sample. The differences between the true and estimated heights were evaluated using the paired t-test, and results of the general formulae were compared with those of each of the stature group-specific formulae. Our results suggest that stature group-specific formulae give more accurate estimates of height, and that this is particularly significant for individuals who are short or tall relative to the average of a population.

“…Tibial length (TL) was measured in centimeters with a standard measuring tape from the medial malleolus to the tibial tuberosity using a modification of the method described by Pelin and Duyar (12). The patient was asked to stand barefoot on a standard balance beam scale while his/her height was measured in centimeters.…”

“…Based on research in the fields of nutrition and forensic anthropology, we selected tibial length as the bedside anthropomorphic measurement for use in a regression model to predict TH and IBW (12). We also chose to test this method, as it seemed to be the most easily and rapidly accessible anthropomorphic measurement, short of measuring the actual height itself.…”

e Abstract-Background: Ideal body weight (IBW), which can be calculated using the variables of true height and sex, is important for drug dosing and ventilator settings. True height often cannot be measured in the emergency department (ED). Objectives: Determine the most accurate method to estimate IBW using true height-based IBW that uses true height estimated by providers or patients compared to true height estimated by a regression formula using measured tibial length, and compare all to the con-

“…Morphometric tibial parameters are considered to of medico-legal importance due to the provision of stature-group-specific formulae for the determination of "personal identity" in circumstances of unknown and unclaimed human remains (Pelin & Duyar, 2003;Akhlaghi et al;Bokariya et al). In the present study all mean morphometric tibial parameters were higher in males than females (Table III).…”
