Background: Body Mass index (BMI) and waist circumference are the predictors of chronic diseases. Anthropometric measurements help to remain healthy. This study aimed at examining the effect of lifestyle on anthropometric changes over the course.
Methods: In this study, 246 individuals were selected according to criteria. Cluster sampling was done in the military barracks. After obtaining consent, anthropometric indices, demographic and food recall were measured and followed to end course. Relationship between lifestyle and anthropometry was determined by linear regression. A p- value less than 0.05 was considered significant.
Results: Mean BMI before the start of training 23.9+3.8 and waist 88.7+0.6 cm and after the period decreased to 22.3+7.0 and 87.9+3.9 cm respectively. Dietary diversity and physical activity before entering to course had statistically significant effect on anthropometric changes during the military period.
Conclusion: BMI and waist circumference decreased during the military training. Dietary diversity and high physical activity prevent anthropometric changes. Further studies of these relationships make it clearer.
