A Study of Height and Weight in the Students of Rasht and Sangar,1989.

SUMMARYLATE The body weight (BW) and height are important creteria for assesment of the health status of children and adolescents. The BW and height curve of guilanian girls and boys may be different from the curve of other areas of Iran and other countries. In autumn of 1989 we studied the BW (with indoor clothes) and the height (without shoes )in 6206 girls and boys in randomly selected schools of Rasht (11 schools)and sangar (10 schools). Upto age 9 years, the mean hieght of Rasht girls and boys is equal ,but from the age of 9 to 14 years, the girls height exceeds that of boys. After the age of 14 years the girls height does'nt increase anymore ,while boys continue to grow. The maximal annual increases of height occur in Rasht girls (5-7cm)at the age of 9.5 -11 years and in boys(6-9 cm) at the age of 13-15 years. The mean BW of Rasht girls at the age of 9-11 years is more than the BW of rasht boys, and beyond this age group is less than Rasht boy BW. The BW of Rasht girls does'nt increase any more after the age of 14 years. The maximal annual increases of BW occur in girls (2.5-5 kg) at the age of 11-14 years and in boys (4-7 kg) at the age of 13-16 years. Sangar girls and boys have equal height upto 14 years old thereafter the girls height does'nt increase any more,but boys height continue to increase.The maximal annual increase of height occur in Sangar girls (4-6 cm)at the age of 10-13 years and in Sangar boys(6-9 cm)at the age of 13-15 years. The mean BW of Sangar girls at the age of 10-13 years is more the mean BW of Sangar boys,and beyond this age group is less than Sangar boy BW.The BW of Sangar girls does'nt increase any more after the age of 14 years ,but the BW of Sangar boys continue to increase . the maximal annual increase of BW occur in Sangar girls (3-6 kg) at the age of 11-14 years and in boys(4-7 kg) at the age of 12 -14 years In conclusion the schoolgirls and schoolboys of Rasht are taller and hevier than the sangar schoolgirls and schoolboys,respectively. The schoolgirls's body weight and height reach a peak at the age of 14 years, but school boys continue to grow even at the age 18 years. The guilanian girls and boys are taller and hevier than the Esfahan girls and boys, but have less body weight and height than the Tehran girls and boys respectively. The guilanian girls and boys are shorter and have less weight than the USA girls and boys ,respectively.
