The growth pattern of children is affected by anthropometric dimensions. This study was aimed to investigate anthropometric factors related to growth of preschool children of a sample population in Iran. This study was performed in year 2011 on 1320 of 4–7 years old preschool children in Arak. To classify, body mass index (BMI), height and weight were recorded. The four contact points (head, back, buttocks, and heels) were maintained against the spine of the stadiometer during measurement. The head was positioned in the Frankfurt plane, and the sliding bar was lowered the crown of the head. Height was measured and recorded by the researchers. A pair of manual calibrated Seca scales was used to measure body mass in kilograms. The participants were least dressed in the uniform. We have classified BMI to four groups as group1, BMI with 10.75–15 and group 2, 3, 4 with 15.1–17 and 17.1–20, 20.1–22.5, respectively. Foot length was recorded as the distance from the posterior aspect of the heel to the most distal aspect of the longest toe. Foot length was measured with subjects standing upright using a foot board, a plastic device with calibrated lineation (in centimeters and millimeters). Analysis showed that sex neither affect on BMI nor foot measurements. The present findings contribute to the understanding of the effect of body mass on the structural development of the pediatric foot and musculoskeletal system. Excessive body mass seems to lead to increased foot length and width.
