 en Validation of the Ejike-Ijeh equations for the estimation of body fat percentage: A random cross-sectional study in adult Nigerians
Ejike, Chukwunonso E.C.C. & Ohanenye, Ikenna C.

Abstract

The Ejike-Ijeh equations for the estimation of body fat percentage makes it possible for the body fat content of individuals and populations to be determined without the use of costly equipment. However, because the equations were derived using data from a young-adult (18-29 years old) Nigerian population, it is important to validate the equations in a wider spectrum of adults. This study is an attempt at such validation. A total of 365 adult Nigerians aged 18 to 80 years (52.9% females) participated in this random cross-sectional study. Standard internationally accepted protocols were followed for all determinations and calculations. Appropriate statistical tools were used to analyse the data generated. The mean age of the subjects was 44±16 years. The differences between the mean ages of both sexes was not statistically significant (P>0.05). Using BMI as a diagnostic, obesity was found in 12.3% of the population (17.1% in females and 7.0% in males). On the other hand, using percent fat mass (PFM), 16.4% (25.4% females and 6.4% males) were found to be obese. Measured PFM correlated positively and significantly (r=+0.635; P<0.001) with the PFM-II in the general population. The correlations were stronger in males (r=+0.736) compared to females (r=+0.563). The Ejike-Ijeh equations appear valid for use in adult Nigerians.
