Equations to predict height from several body segments have been developed. However, those that use the knee height are limited by the need of an instrument with high cost (anthropometer). Thus, the aim of this study was to develop a prediction equation from the leg length by using a tape measure. Leg length and height was measured in 180 subjects, with ages 30-59 years that attended the Ambulatorio Docente Asistencial of the University Hospital of Caracas, from April to June of 2002. In order to determine the correlation degree of each measurement with height, the existent correlation between height and each one of the studied variables (leg length, sex, age) and between the variables to one each other was calculated by means of the Pearson's correlation coefficient. Linear regression analysis was done to estimate the height in each gender and the results were tested on an independent sample. The generated equations achieved a very good correlation with the real height and the standard error was calculated. Thus, in those subjects in whom assessment of the real height is not possible by conventional means, it is possible to use height prediction equations from simple techniques and equipment accessible to the whole health care staff.
