ABSTRACT Objective: To estimate the prevalence of overweight among Brazilian adults aged 20 to 59, according to sociodemographic characteristics, health-related behaviors, and food consumption. Methods: A cross-sectional study based on data from a population-based survey in a major metropolitan city in the state of São Paulo, Brazil, conducted between 2015-2016. Prevalences and prevalence ratios were estimated using Poisson regression; food consumption means were estimated using linear regression. Results: We analyzed data from 855 adults, 61% of whom were overweight. The prevalence of overweight was significantly higher among males, those aged 30 or older, with 8 to 11 years of education, and those who reported eating more than they should. The body mass index was significantly associated with hypertension, diabetes, high cholesterol, waist-to-height ratio, taking weight-loss medications, overeating, and the habit of checking labels. Overweight adults reported eating meat with visible fat and drinking soda more frequently than those not overweight. Overweight adults reported eating significantly more grams of food daily and had a higher intake of energy, total fat, saturated fats, trans fats, carbohydrates, protein, insoluble dietary fiber, sodium, and potassium. Their diets had a higher glycemic load when compared to participants who were not overweight. Conclusion: Adults with and without overweight differed in their sociodemographic, dietary, and clinical characteristics. Diet quality was similar between both groups, suggesting a need for improving dietary habits in this population regardless of body weight.

RESUMO Objetivo: Estimar a prevalência de excesso de peso entre adultos brasileiros, de 20 a 59 anos, segundo características sociodemográficas, de comportamentos relacionados à saúde e quanto ao consumo alimentar. Métodos: Estudo transversal, de pesquisa de base populacional, em uma cidade metropolitana de São Paulo - Brasil, conduzida entre os anos de 2015 e 2016. Foram estimadas as prevalências e as razões de prevalência por meio da regressão de Poisson, e as médias de consumo alimentar pelo uso da regressão linear. Resultados: Foram analisados dados referentes à 855 adultos, 61% destes apresentavam sobrepeso. A prevalência de excesso de peso foi significativamente maior entre: homens, com 30 anos ou mais, pessoas que possuíam entre 8 e 11 anos de estudo e entre aqueles que acreditavam comer mais do que deveriam. O índice de massa corporal foi significativamente associado à hipertensão, diabetes, colesterol alto, razão cintura-estatura, uso de medicamentos, comer mais do que deveria e o hábito de checar rótulos. Adultos com excesso de peso ingeriam carnes com gordura e refrigerantes em maior frequência quando comparados à adultos com peso saudável. Adultos com excesso de peso consumiam, significativamente, mais gramas de alimentos por dia e apresentaram maior ingestão de calorias, gorduras totais, saturadas e trans, carboidratos, proteína, fibras insolúveis, sódio e potássio. A dieta deles continha uma maior carga glicêmica quando comparada àqueles com peso saudável. Conclusão: Adultos com e sem excesso de peso, diferiram quanto às características sociodemográficas, dietéticas e clínicas. A qualidade da dieta foi similar em ambos os grupos, o que sugere a necessidade de melhora dos hábitos alimentares da população, independentemente do peso corporal.

Abstract Objectives: To estimate the prevalence of the perception of eating more than one should and the associated factors in adolescents, and to analyze differences in dietary indicators according to the perception of overeating. Methods: This is a cross-sectional population-based study with a sample of 912 adolescents, participants of a food consumption survey conducted in 2015-2016, in Campinas, SP, Brazil. Results: The prevalence of the perception of eating more than one should was 35.0%, and higher in those who declared themselves non-white, those who had excess weight, those who had high waist circumference, those who would like to change their weight, those who did something to lose weight, and those who evaluated themselves as fat. The prevalence rates were also higher in those who perceived the quality of their diet as poor, who had higher frequencies of consumption of sweets, soft drinks, cold meats, and lower frequencies of consumption of fruits, raw vegetables, and breakfast up to three times a week. Among those who considered themselves as overeating, higher intakes of energy, carbohydrate, protein, fat, added sugar, and sodium were observed, and prevalence rates of 38.5% for overweight and 66.2% for obesity were identified. Conclusion: The perception of eating more than one should was associated with unhealthy eating practices, the self-assessment of a poor quality diet, dissatisfaction with weight, and inadequate nutritional status. There is a need for further studies to investigate the application of the question “Do you think that you eat more than you should?” as a health behavior indicator.

Resumo Objetivou-se estimar as prevalências de autoavaliação da qualidade da dieta de adolescentes e identificar os motivos de não a considerar muito boa/boa; calcular o escore global e de cada componente do Índice de Qualidade da Dieta Revisado (IQD-R) segundo as categorias de autoavaliação. Estudo transversal de base populacional com amostra por conglomerados e em dois estágios, realizado em Campinas-SP. Foram analisadas 891 entrevistas. As prevalências de autoavaliação da qualidade da dieta foram de 57,3% como muito boa/boa, 34,6% como regular e 8,1% como ruim/muito ruim. A autoavaliação como regular ou ruim foi associada ao consumo de doces, salgadinhos/biscoitos, cereais integrais (10-14 anos) e de fast-food (15-19 anos). Para os que foram classificados com pior qualidade da dieta (1º tercil dos escores do IQD-R), 52,5% consideravam a alimentação muito boa/boa e apenas 13,1% como ruim/muito ruim. O escore do IQD-R revelou-se significativamente menor nos que achavam a alimentação ruim (50,0 pontos) comparados aos que disseram muito boa/boa (55,4 pontos). Os que consideravam a alimentação ruim apresentaram consumo inferior de frutas, cereais integrais, e superior de gorduras sólidas e açúcares. Os achados revelam incoerência na autoavaliação da qualidade da dieta em relação aos escores insatisfatórios observados.

Abstract The aim was to estimate the prevalence of categories of self-rated diet quality according to adolescents, identify the reasons for not considering the diet very good/good as well as calculate the global Revised Brazilian Healthy Eating Index Revised (BHEI-r) score and component scores according to the self-assessment categories. A cross-sectional population-based study with two-stage stratified cluster sampling was conducted in Campinas-SP. A total of 891 adolescents were analyzed. The proportions of very good/good, fair and poor/very poor self-rated diet quality were 57.3%, 34.6% and 8.1%, respectively. Fair/poor/very poor self-rated diet quality was associated with the consumption of candy/sweets, snacks/cookies, whole grains (10-14 years) and fast food (15-19 years). Among those classified as having poor diet quality (1st tertile of BHEI-r scores), 52.5% considered their diet to be very good/good and only 13.1% considered their diet to be poor/very poor. The BHEI-r score was significantly lower among those who thought their diet was poor (50.0 points) compared to those who thought their diet was very good/good (55.4 points). Those who considered their diet to be poor had lower intakes of fruit and whole grains as well as higher intakes of solid fats and sugars. The findings reveal incoherence between self-rated diet quality and the observed unsatisfactory diet scores.
