Using control chart to analyze body mass index

Abstract

This paper discusses three techniques that can be used to analyze health risk factors. The focus is to determine if each of these techniques has comparative advantage(s) or otherwise in analyzing health status. The benchmark categorizations for body mass index (BMI) and the percentage body fat (PBF) are explicitly defined by World Health Organization classification and American council on exercise. The body mass index, percent body fat and the Pondera index using conventional height, weight data collection technique and the proposed toe to ankle data collection procedure (TAT) to analyze if the body mass index and the other procedure provide equivalent results interms of health status classification. The analysis revealed that both data collection techniques have comparable output. Though, the TAT approach based on the control chart analysis is tractable to underweight than obesity while the contrary is true for the height data collection approach. Both data collection procedures showed comparative performance in terms of normal weight and overweight tractability. The analysis depicts information regarding life expectancy and health risk factors associated to body weight and composition.
