The Objective this study is to compare the consumption of articial sweeteners by sex and BMI status among university students in Peru, Chile, Guatemala and Panama. Survey of consumption of articial sweeteners containing foods was designed and applied, adapted for each country with pictures of surveyed foods. After the survey application, a total of 1,229 participants male and female both university students from 4 dierent Latin American countries: Chile (n=473); Panama (n=300); Guatemala (n=253); Peru (n=204) were submitted to a anthropometry measeurement. Over 80% of students ate at least 1 food that contained articial sweeteners, acesulphame-k, sucralose, and aspartame had the highest levels of consumption. Females in Chile and Guatemala ate the most sucralose (25.7 (6.6-50.9), p<0.05; 38.3 (15.1-82.5). Males in Panama ate the most acesulphame-k, (35.3 (11.5-91.5), p<0,05). Females had a positive correlation between articial sweetener consumption and BMI for: acesulphame-k, aspartame and cyclamate. Males had a negative relationship between acesulphame-k, aspartame and BMI (p<0.05). We found a high consumption of articial sweeteners among both male and female Latin Americ an university students, with dierences by country, sex and BMI status.
