With the purpose to compare the prevalence of obesity in males and females adolescents in a high school from the metropolitan area of Guadalajara, Mexico, a cross sectional randomly design, with 105 males and 105 females of 12 to 16 years old were included. They were healthy and authorized consent was obtained. Variables included: age, gender, BMI, tricipital and sub scapular skin fold, percent of body fat (%BF) (Slaughter's equation) and bioelectrical impedance analysis (BIA). A student T test, chi square, OR (confidence intervals 95%) and the Pearson coefficient for the correlation between the %BF obtained by the Slaughter equation and BIA methods were obtained. Mean age was 13.9 and 13.5 years for males and females. The %BF by slaughter's equation and BIA was significantly higher in females (29.9 and 26.9% respectively) than males (24.4 and 15.4%), (p<0.001). BIA tended to significantly overestimate the %BF in males (p<0.01). Both methods were highly correlated in females (r = 0.807) and males (r = 0.856). Percentage of overweight was similar in males and females (22 vs. 20%); but, the percentage of obesity was significantly higher (p = 0.037) in males (11.4%) than in females (3.8%). The %BF was higher in females and the frequency of obesity was higher in males. BIA seemed to overestimate %BF in males, although there are high correlations between slaughter equation and BIA in both genders.
