Applications of BMI or BSI: Differences and Revisions According to Age and Height

Table 4

Healthy weights for people with heights of 1.3 m and above obtained with the BSI formula using $a_S=12.5\hspace{0.17em}kg/m^3$. For individuals shorter than 1.3 m the BMI has been used with $a_M=15.9$ kg/m². Mass ranges are based on the individual $\sigma (a_{Mi})$ values for heights below 1.3 m, and on $\sigma (a_{Si})$ values for heights above 1.3 m taken from (1) and (12). In column 1 are listed the heights $H_i$ of the people (in meters), in column 2 are given the ideal healthy weights or masses $w_i$ (in kg) and in column 3 are listed individual healthy weight ranges (also in kg). For heights between the listed values an interpolation between the neighbouring weights and weight ranges should be sufficient.
