Abstract
Objective
To explore the associations between the consumption of three categories of ultra-processed food (sugary beverages, sweet, and salty snacks) and body mass index (BMI) among Chilean university students.
Methods
We conducted a multi-center, descriptive study among 2,039 students from 6 Chilean universities. Food consumption was surveyed using a validate food survey. That height and body weight were objectively measured to calculate BMI for determining weight status, and also, tobacco use and physical activity were measured.
Results
An intake equal to or higher than 1 serving of sugary beverage a day was associated with greater odds of obesity in university students (OR:1.32 [95% CI: 1.00, 1.74]), 2 servings/day (OR: 1.30 [95% CI: 1.04, 1.50]), and 3 servings/day (OR: 1.39 [95% CI: 1.05, 1.80]). Neither consumption of sweet nor salty snacks (≥1 servings/day) related to differential odds of obesity: (OR: 0.83 [95% CI: 0.42, 1.64]) and (OR: 1.79 [95% CI: 0.93, 3.41]), respectively.
Conclusion
In a sample of Chilean university students, consumption of sugary beverages, and not consumption of sweet or salty snacks, was associated with obesity.
