Relationship between Standing Height and Popliteal Height.

Linear measurements have been assumed to have linear correlation with standing height that may not be so. The aim of this study was to establish the actual relationship between standing height and popliteal height. Four hundred and eighty (480) students were randomly selected from eight public secondary schools and eight private secondary in Ibadan, South Western Nigeria with a mean age of 14 years (n = 480, SD = ± 2.3 years). The anthropometric data were collected based on age rather than levels in schools and gender since the schools were co-educational. The data generated were analyzed using descriptive statistics such as standard deviations, minimum values, maximum values. The fifth, fifty and ninety-five percentiles of the data were determined using Excel Microsoft Package. The popliteal height was subjected to curve estimation using SPSS 16.0 Statistical Package. The model with p < 0.005 and highest coefficient of determinations was selected as the best model to predict the relationship between the standing height and popliteal height. The results of the study show that the standing height correlate more non-linearly correlated with popliteal height than being linear. [ABSTRACT FROM AUTHOR]
