Random cluster method was applied in both urban&nbsp; (84%) and rural&nbsp; (16%) areas of Isfahan province. BMI values were measured and then categorized using reference growth charts from the Centers for Disease Control and Prevention&nbsp; (CDC 2000). Weight‑for‑age and stature‑for‑age indices were assessed as well in accordance with CDC growth charts.<br /><strong>Results:</strong> The overall prevalence of underweight, overweight, and obesity was 13.9, 10.4, and 5.7%, respectively. Boys and students of urban areas showed a higher tendency of obesity and overweight in comparison with girls and rural students respectively. Furthermore, rural students had poorer status in both weight‑for‑age and stature‑for‑age indices. In addition, educational level was the only statistically efficacious factor.<br /><strong>Conclusions:</strong> This study and previous ones demonstrated that children and adolescents&rsquo; nutritional status, which strongly affect general health status of individuals, should receive more exquisite attention.<br /><strong>Keywords: </strong>Body mass index, child, malnutrition, nutritional status, obesity, overweighthttp://ijpm.mui.ac.ir/index.php/ijpm/article/view/1511http://ijpm.mui.ac.ir/index.php/ijpm/article/download/1511/1794
