Degree of food processing and association with overweight and abdominal obesity in adolescents

ABSTRACT

ABSTRACT Objective To evaluate the association between the degree of food processing, overweight, and abdominal obesity in adolescents. Methods This is a cross-sectional study, with 576 adolescents aged 10 to 17 years, of both sexes. Food consumption was collected using the Food Frequency Questionnaire and foods classified as in natura or minimally processed, processed foods associated with culinary ingredients, and ultraprocessed foods. Sociodemographic data, body mass index, waist circumference and waist-to-height ratio were collected. The analysis was evaluated by the Mann-Whitney test and prevalence ratio with 95% confidence interval, considering p<0.05. Results An intake above the third quartile of processed foods associated with culinary ingredients (prevalence ratio of 1.64; 95%CI 1.12-2.42) and ultraprocessed (prevalence ratio of 1.58; 95%CI 1.07-2.34) was associated with a higher prevalence of overweight. Consumption above the third quartile of ultraprocessed foods was associated with a higher prevalence of abdominal obesity, assessed by waist circumference (prevalence ratio of 2.48; 95%CI 1.41-4.36), and waist-height ratio (prevalence ratio of 2.09; 95%CI 1.11-3.92). Conclusion A higher consumption of processed foods associated with culinary ingredients was related to being overweight, and ultraprocessed foods with overweight and abdominal obesity.
