RESUMO:

Eating habits in adolescence are characterized by high consumption of processed and ultra-processed foods and it may result in micronutrient deficiency and the early occurrence of chronic non-communicable diseases. This study aimed to evaluate the consumption of processed and ultra-processed foods and the relationships between the prevalence of nutrient inadequacy and cardiometabolic risk factors in adolescents. A cross-sectional study was conducted with 444 adolescents from public schools in the city of Natal, Northeast of Brazil. We investigated the variables family history of risk factors for cardiovascular disease, maternal schooling, anthropometric nutritional status, sexual maturation, blood pressure and lipid profile. Dietary and food intake data were obtained by two 24-hour recalls. The foods consumed were classified according to the type of processing in processed and ultra-processed. The prevalence of micronutrient inadequacy was estimated using the Estimated Average Requirement (EAR) as the cut-off point, except for the iron in which the manually determined probabilistic approach was used. An ordinal logistic regression was performed to estimate the relationship between the energy percentage of processed and ultra-processed foods and the prevalence of micronutrient inadequacy and cardiometabolic risk factors. It was observed that 91.9% of adolescents were in the age group between 10 and 13 years. The consumption of processed foods was 10.4 (1.2)% from total energy in 25th-50th percentiles, as well as the consumption of ultra-processed food was 31.5 (2.2)% from total energy also in 25th-50th percentiles. The most consumed food groups were "bread roll" (7.7% of total energy) and "processed meat" (4.8% of total energy) in the processed food group and "cakes, pies and biscuits" (13.3% of total energy) and "sliced loaf" (5% of total energy), in the ultra-processed food group. There was a high prevalence of inadequate consumption of vitamins D, folate, vitamin E, calcium and selenium, in both sexes, in the age groups of 10 to 13 years and of 14 to 19 years. The higher consumption of processed foods was positively associated with the increase in the prevalence of inadequate vitamin B1 (p = 0.04, RP 0.55) and selenium (p <0.01, PR = 1.97). Higher proportions of energy from ultra-processed foods were associated with inadequate vitamin B1 (p = 0.03, PR = 0.49) and zinc (p <0.01, PR = 0.49). The higher consumption of processed food was associated with hypercholesterolemia (p = 0.04, RP = 3.08) and hypertriglyceridemia (p = 0.02, PR = 3.79), as well as adolescents whose mothers had elementary schooling level (p <0.01, RP = 1.72). Excessive consumption of processed and ultra-processed foods by adolescents may reflect on an increase in the prevalence of inadequate nutrients, especially vitamin B1, selenium and zinc, as well as being associated with cardiometabolic risk factors, implying damage to health conditions in the short and long term.
