Different calculation formulas for ideal body weight and actual/ideal body weight index estimation in post-traumatic stress disorder patients

Aim: The aim of this study was to investigate which is the most acceptable model for body mass index evaluation by a standard general pattern, since the one of the oldest bioantropological issues is what is the mass that a person should have, with a certain height, constitution, gender, age and other important determinants. Methods: This prospective study included 78 patients, male gender, divided into two groups: PTSD - group (44 patients) and control group (34 patients). Those were heterogeneous groups according to age and educational structure, where the 30's and 40's are dominant for age and high school education is dominant for education. Calculations of body mass index were performed using standard general pattern, applying different methodologies to obtain the theoretical mass values (Broca's, Azerad's, American insurance company's, Demelov's) Results: There are significant differences between the average values of body mass index calculated by the general standard pattern, depending on the different kind of calculation of theoretical mass used within the PTSD group  and control group.  Conclusion: The correlation coefficient indicates that nutritional index obtained by standard general pattern by use of different methodologies for determining a theoretical body mass is very similar for measurment and calculation of nutitinal state within the PTSD and control group. However, compared to correlation matrix we obtained within the PTSD group the coefficients of correlation  levels were slightly lower within the control group Kayword: body mass index, theoretical mass, PTSD
