Background: An association between increased consumption of sugary drinks and various metabolic diseases has been reported. Objective: To evaluate the effect of consumption of sugary drinks on overweight and obesity over a period of 12 months among 15 to 19 years old in Mexico. Methods: A prospective study with a 12 month follow-up was implemented. Variables including weight, height and waist circumference (WC) were measured, and the z score of body mass index (BMI) was calculated. A questionnaire on the consumption of 19 beverages was applied. A binomial logistic regression analysis was used to evaluate the prediction of increased BMI and WC resulting from the consumption of the beverages. Results: At the end of the study there was a rention of 89% (1,344). The average age was 15 years old, 55% were women. The prevalence of overweight and obesity found was 33%. The results determined that 25% of participants consumed more than 50 g of sugar per day from beverages. Those participants consuming 50 g of sugar or more per day had a higher risk for increased WC ≥ 2 cm (RR = 1.19; 95% CI, 1.03-1.39, p = 0.02). The participants that had been consuming sugary drinks for twelve months compared to those with decreased consumption of 10 g/day, were 71% more likely to have increased their BMI score ≥ 2 (RR = 1.71; 95% CI, 1.03-2.86, p = 0.039). Conclusion: The high consumption of sweetened beverages increases the likelihood of being heavier and having a larger waist circumference.
