Clinical Trial Summary

The goal of this clinical trial is to learn about variability of gene SCD and MT-ATP6 in describe participant population and health conditions. The main questions it aims to answer are: • whether there is variation in genes between obese and normal weight individuals Participants will get body weight and high was assessed using the medical scale and stadiometer, then, basis on obtained results, the Body Mass Index (BMI) will be calculated. Next, participants get determine the body composition and body composition analysis by bioelectrical impedance method to determined: Visceral Adipose Tissue (VAT in cm2 and %), Subcutaneous Adipose Tissue (SAT in cm2 and %), and the VAT/SAT ratio was also determined. Then order to examine the sequence of the genes, swab will take from the oral cavity (cheeks and palate) using sterile swab. The research was carried out at the Department of Dietetics and Clinical Nutrition (Medical University of Bialystok).


Clinical Trial Description

The approved of the Bioethics Committee of the Medical University, No. APK.002.407.2020, was obtained for the study. 116 people meeting the inclusion criteria were included in the intervention and observational study. The research was carried out at the Department of Dietetics and Clinical Nutrition at the Faculty of Health Sciences of the Medical University of Bialystok. The study took place from the April to the September 2021. The analysis were performed in the morning, fasting, without intensive physical ac-tivity. Body weight and high was assessed using the medical scale and stadiometer with an accuracy of 0.01 kg for the body weight and 0.5 cm for the body high. Then, basis on obtained results, the Body Mass Index (BMI) was calculated.Basis on the obtained results the participants were divided into the study group (n=75) and control group (n=41). The study group consisted 46 women and 29 men with primary obesity (BMI=30.0-39.9 kg/m2). The control group consisted 31 women and 10 men with normal body weight (BMI=18.5-24.9 kg/m2). In order to determine the body composition of participants, a body composition analysis by bioelectrical impedance method was conducted, which enabled the assessment of the following parameters: total body fat mass (kg), total percentage of body fat (%), total percentage of free fat mass (%). The area of adipose tissue in the transverse section to the abdomen was also deter-mined: Visceral Adipose Tissue (VAT in cm2 and %), Subcutaneous Adipose Tissue (SAT in cm2 and %), and the VAT/SAT ratio was also determined. To determine the TOFI phenotype of abdominal fat distribution VAT/SAT ratio was used- above 1 for men and above 0.9 for women. Next swab from the oral cavity was took. To isolate DNA from the swabs, was used ready kit from A&A Biotechnology. After it we did the PCR reactions with the appropriate primers and clean up after PCR reaction was did. Next we prepared the samples for Sanger sequencing. When we get the sequences, we used the genetics programs: Bioedit, Chromas, DnaSP, Arlequin, Mega, Genepop to get number of haplotypes, genes variability, F statistics, haplotype diversity, haplotypes network and genetic tree of haplotypes. ;
