We describe the changes in the prevalence of overweight and obesity in 4606 students that applied to a Mexican University during 1994 to 2008. The mean (± standard deviation [SD]) age was 17.7 ± 1.2 years-old. Progressive and significant increments of bodyweight (female [F] = 2.6, P = 0.03), body mass index (BMI) (F = 4.4, P = 0.001), and waist circumference (F = 30.08, P < 0.0001) in women, and bodyweight (male [M] = 8.9, P < 0.001), BMI (M = 10.4, P < 0.001), and waist circumference (M = 13.01, P < 0.001) in men were observed. A significant increment (P < 0.05) in the prevalence of overweight since 1994 (n = 87, 12.1%) throughout 1997 (n = 102, 14.1%), 1998 (n = 133, 18.4%), 1999 (n = 1993, 26.8%), and 2008 (n = 206, 19.9%) was documented. Similarly, the prevalence of obesity had a significant increment in all students evaluated (P < 0.0001) since 1994 (n = 29, 13.2%) through 1997 (n = 11, 5.0%), 1998 (n = 45, 20.5%), 1999 (n = 53, 24.1%), and 2008 (n = 82, 37.3%). The increment was significant in both women (P = 0.02) and men (P < 0.001). In summary, we report a significant increment in the prevalence of overweight and obesity in Mexican students living in an urban setting over a time period of 14 years.
