The aim of this study was to evaluate body composition indices and related factors.

Research method: The statistical population of this study included all male employees of the National University of Fars Province. 41 people were selected by simple random sampling. To collect data, a tape measure, digital scale, and body composition analyzer were used. The data were analyzed using SPSS 26 software. Descriptive statistics, Pearson correlation coefficient, and one-way analysis of variance (ANOVA) were used to analyze the data. The significance level was set at 0.05.

Findings: The results of the study showed that the average body mass index was 27.676 ± 3.420. Based on the BMI classification, 14.6% of the employees (6 people) were in the normal range, 58.5% (24 people) were in the overweight range, and 26.8% (11 people) were in the obese range. The mean body fat percentage was 28.188% ±5.630, the mean visceral fat level was 10.27% ±3.592, the mean skeletal muscle mass was 34.293% kg ±4.409, the mean fat mass was 24.310 kg ±7.041, the mean lean mass was 60.749 kg ±7.395, the mean waist-to-hip ratio was 0.953 ±0.0544, and the mean muscle mass index was 8.444 ±0.730.

Discussion and Conclusion: This study showed that employees of the National University of Fars Province with an average body mass index in the overweight range and high levels of visceral fat are at risk of physical problems. The proposed model, focusing on physical activity, diet, lifestyle modification, and psychological support, can help improve employee health.
