Evaluation of Anthropometric Measurements and Biochemical Parameters in Non-Alcoholic Fatty Liver Patients and Healthy Individuals

NAFLD patients included in the study should sign a voluntary consent form, do not consume alcohol, be between 30-64 years old, have been diagnosed with NAFLD by applying to the gastroenterology outpatient clinic, have no other diseases, and should not use medication. Healthy individuals; they were required to sign the voluntary consent form, not consume alcohol, be between 30-64 years old, and not have any acute or chronic diseases. Individuals outside these criteria were not included in the study. The reason for the 30-64 age limit for individuals with NAFLD in the study is that NAFLD is more common in this age group. The same criteria were also taken into account in healthy individuals to avoid differences between groups. Individuals who met the inclusion criteria of the study and accepted to participate in the study voluntarily were selected by random sampling method and the sample of the study was formed. For the study, research permission was obtained from Gülhane Training and Research Hospital and ethical approval of the study from Ankara University Ethics Committee (56786525-050.04.04/236883). Written and verbal consent was obtained from the patients before starting the study. The research was conducted in accordance with both the Declarations of Helsinki and Istanbul. Biochemical Parameters Fasting blood glucose, total cholesterol, triglyceride, HDL, VLDL, LDL, ALP, AST, ALT and GGT values of the individuals participating in the study were obtained from the files with the permission of the patients.

Anthropometric Measurements The data were collected using a questionnaire form and face-to-face interview method. In the study, individuals' body weight (kg), height (cm), waist circumference (cm), hip circumference (cm), neck circumference (cm) measurements were taken in accordance with the method, and these measurement values were used to measure BMI, waist-height ratio, waist-hip ratio, body composition (fat mass, muscle mass, etc.), body shape index, body roundness index, visceral adiposity index measurements were calculated. Body mass index was calculated by dividing the body weight by the square of the height. Other anthropometric measurements and ratios were calculated using appropriate formulas.
