Previous issue date: 2017-11-30 / Os h?bitos alimentares na adolesc?ncia s?o caracterizados pelo elevado consumo de alimentos processados e ultraprocessados, e podem ter como consequ?ncia a defici?ncia de micronutrientes e a ocorr?ncia precoce de doen?as cr?nicas n?o-transmiss?veis. Este estudo teve como objetivo avaliar o consumo de alimentos processados e ultraprocessados e as rela??es com a preval?ncia da inadequa??o de nutrientes e os fatores de risco cardiometab?licos em adolescentes. Foi realizado estudo transversal com 444 adolescentes de escolas p?blicas no munic?pio de Natal, Nordeste do Brasil. Investigou-se as vari?veis hist?ria familiar de fatores de risco para doen?a cardiovascular, escolaridade materna, estado nutricional antropom?trico, matura??o sexual, press?o arterial e perfil lip?dico. Os dados de consumo alimentar e diet?tico foram obtidos por dois recordat?rios de 24 horas. Os alimentos consumidos foram classificados quanto ao tipo de processamento. Estimou-se a preval?ncia de inadequa??o de micronutrientes utilizando a Estimated Average Requirement - EAR como ponto de corte, exceto para o ferro em que foi utilizado o m?todo da abordagem probabil?stica manualmente determinada. Foi realizada uma regress?o log?stica ordinal para estimar a rela??o entre o consumo de alimentos processados e ultraprocessados com a preval?ncia de inadequa??o de micronutrientes e com os fatores de risco cardiomateb?licos. No P25-P50 o consumo de alimentos processados foi de 10,4 (1,2)% e o de ultraprocessados foi de 31,5 (2,2)%, do total de energia. Registrou-se elevadas preval?ncias de inadequa??o de consumo das vitaminas D, folato, vitamina E, c?lcio e sel?nio, em ambos os sexos. O maior consumo de alimentos processados foi positivamente associado ao aumento na preval?ncia de inadequa??o de vitamina B1 (p=0,04; RP 0,55) e sel?nio (p<0,01; RP=1,97) e o maior consumo de alimentos ultraprocessados foi associado a inadequa??o de vitamina B1 (p=0,03; RP=0,49) e de zinco (p<0,01; RP=0,49). O maior consumo de processados foi associado a hipercolesterolemia (p= 0,04; RP= 3,08) e a hipertrigliceridemia (p= 0,02; RP= 3,79). A baixa escolaridade materna tamb?m foi associada ao maior consumo de alimentos processados (p< 0,01; RP= 1,72) e ultraprocessados (p= 0,03; RP= 0,36). O consumo excessivo de alimentos processados e ultraprocessados por adolescentes associa-se ao aumento da preval?ncia de inadequa??o de nutrientes, principalmente vitamina B1, sel?nio e zinco, bem como a fatores de risco cardiometab?licos, implicando em preju?zos nas condi??es de sa?de a curto e longo prazo. / Eating habits in adolescence are characterized by high consumption of processed and ultraprocessed foods and may result in micronutrient deficiency and the early occurrence of chronic noncommunicable diseases. This study aimed to evaluate the consumption of processed and ultraprocessed 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, Northeastern Brazil. The variables family history of risk factors for cardiovascular disease, maternal schooling, anthropometric nutritional status, sexual maturation, blood pressure and lipid profile were investigated. Dietary and food intake data were obtained by two 24-hour recalls. The foods consumed were classified according to the type of processing. 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 consumption of processed and ultraprocessed foods and the prevalence of micronutrient inadequacy and cardiomathobolic risk factors. At P25-P50 the consumption of processed foods was 10.4 (1.2)% and the ultraprocessed consumption was 31.5 (2.2)%, of the total energy. There was a high prevalence of inadequate intake of vitamins D, folate, vitamin E, calcium and selenium in both sexes. The higher intake of processed foods was positively associated with an increase in the prevalence of inadequate vitamin B1 (p = 0.04, PR 0.55) and selenium (p <0.01, PR = 1.97) and higher intake of (p = 0.03, PR = 0.49) and zinc (p <0.01, PR = 0.49). The highest processed consumption was associated with hypercholesterolemia (p = 0.04, PR = 3.08) and hypertriglyceridemia (p = 0.02, PR = 3.79). Low maternal schooling was also associated with higher consumption of processed (p <0.01, PR = 1.72) and ultraprocessed foods (p = 0.03, PR = 0.36). Excessive consumption of processed and ultraprocessed foods by adolescents is associated with an increase in the prevalence of inadequate nutrients, especially vitamin B1, selenium and zinc, as well as cardiometabolic risk factors, implying short-term and long-term health losses.
