UKURAN FISIK ANAK NORMAL USIA 7-12 TAHUN (Studi Pendahuluan pada Siswa SDN Petompon 1 Semarang)

Abstract

Backround:Both genetics and environmental factors could cause differences in child’s physical measurements. Thus, standard curves are needed to evaluate the presence of disorder or disturbance caused by those two factors. A huge number of samples are needed to make a reference curve. This research is aimed as a preliminary study to find the physical scales of normal children in Indonesia. Methods: This is a preliminary study with descriptive observasional design. The data were obtained by cross-sectional method between March-June 2011. Measurements were done on weight, standing height, sitting height, occipitofrontal circumference, armspan, inner canthal distance, outer canthal distance, interpupillary distance, ear length, chest circumference, internipple distance, and mid upper arm circumference, on 7 to 12 years old students of SD Petompon 1 Semarang. The data were then analyzed with Microsoft Excel, and presented in tables and graphs. The mean value of each measurement was plotted to corresponding reference curve. Result: The physical scales of 276 students, consisted of 128 boys and 146 girls, who met the inclusion criteria were obtained. It was showed that all physical measurement results on each age category were considered normal according to their corresponding reference/standard curve, except for sitting height and arm span. On some measurements, like weight, standing height, head circumference, interpupillary distance, internipple distance, and mid upper arm circumference, the means were tend to be lower compared to the means of their corresponding reference curve. Conclusion: Most of the physical scales of 7-12 years old children were considered normal according to their corresponding reference curve. However, their means were tend to be lower then the means of corresponding reference curve. A similar integrated study with larger scale is necessary to providestandard reference curves for Indonesian children.
