Body Mass Analysis for Patients Undergoing Surgical Intervention: A Cross-Sectional Study.

Background and Aim: Bioelectrical Impedance Analysis is a reliable, noninvasive, objective, and cost-effective body composition assessment method used in clinical practice. Body composition provides information for precise nutrition intervention in the perioperative period to improve patients' postoperative outcomes. The study evaluates and estimates the nutritional status of patients undergoing surgical intervention. Patients and Methodology: A cross-sectional survey took place from March 2024 to October 2024 to examine the body composition, muscle-fat analysis, and body-calculated data of 2368 adult patients (aged 18 years and older) from Erbil Teaching Hospital in Erbil City utilizing a convenience sampling technique from those patients who were admitted to the hospital for surgical intervention. Data were collected using the InBody machine 270, including two parts: the first was related to demographic data, while the second consisted of body composition. Results: The analysis showed that men generally had higher levels of total body water, protein, minerals, skeletal muscle mass and fat-free mass, while women indicated higher levels of visceral fat and percent body fat, as both genders show waist-hip ratios and levels of obesity above the average. Conclusion: The study concluded that gender differences have a significant impact on the presence of gender body composition differences.
