| Summary: | The present survey is a correlation study designed to determine extent and type of relation between mid-arm circumference and weight in order to offer a scale for assumption of weight. 390 healthy, adults who are resident in Tehran and between the ages 18-65 were selected from visitors at three hospital censers at random. Input accumulation was carried out by means of a questionnaire and checklist. The checklist consisted of anthropometery information (height, weight, mid- arm circumference). All of the measurements were obtained by means of on e person and identical instruments. The results of this study are summarize d in 22 tables. T-test and analysis variance were used to determine the relation between personal character, weight and mid.arm circumference. The results showed that occupation, sax and cigarette smook ing influence the size of the left and right mid-arm circumference and weight. But there is no significant difference between the left and right mid-arm circumference and weight among different athletic groups, different incomes groups and left handed or right handed persons. Correlation coefficient was used to determine the relation between the left and right mid-arm. Circumference and weight. There was a high positive relation between the size of both arms an d weigh t. The relation between left arm an d weight (r= 0.82) was a little more than the relation between the right mid-arm circumference and weight (r==0.81). The equation of regression was applied f or assumption of weight on the basis of size of the mid-arm circumference. The results indicate that with the increase of one centimeter of the size of the left or right mid-arm circumference in men or women the weight increases 26 kg on the average.
