Sažetak
Arm span and standing height were measured in 289 boys and 337 girls aged 6–15 years who were free from physical deformities which can affect stature or arm span. The arm span exceeded height in all age groups of boys and in older girls. At the age of 7, 11 and 12 years girls were significantly taller than the boys and had longer arm span while at the age of 15 years, the trend was opposite. The mean difference between the two anthropometric parameters for boys was 5.45±4.21 cm (t=3.556, p<0.001) and for girls was 4.94±4.96 cm (t=3.542, p<0.001). Correlation coefficient between height and arm span measurements for Malawian boys was 0.983 and for girls was 0.986. Height, arm span and height-arm span difference increased with age of children while height to arm span ratio decreased. The gender difference in height-arm span differences was only significant at the age of 15 years. Multiple regression and cross validation were performed. Height of Malawian children of both sexes can be estimated from equation:
Height (cm) = 15.756 + (0.168 x age) + (0.839 x arm span) (SEE=0.760, R2=0.988).
