Is the APLS formula used to calculate weight-for-age applicable to a Trinidadian population?

BMC Emergency Medicine, 08/03/2012

The APLS formula slightly underestimates the weights of children in the Trinidad population, although the degree of underestimation is less than has been observed in similar studies in developed countries. While both the Luscombe formula and the formula derived from the results of this study give an estimated weight that is closer to the measured weight of children in Trinidad, but the percentage of children falling within 10% of the estimated weight is not significantly different when comparing these three formulae. In light of this, it is recommended that the APLS formula should continue to be used to estimate the weight of children in resuscitation situations in Trinidad, as it is well known, easy to calculate and widely taught in this setting.
