Artigo Diet quality and associated factors in brazilian undergraduates during the COVID-19 pandemic(Frontiers in Nutrition, 2023-05) Maciel, Bruna Leal Lima; Galvão, Liana Letícia Paulino; Santos, Thanise; Slater, Betzabeth; Lyra, Clelia de Oliveira; Rolim, Priscilla Moura; Ramalho, Alanderson; Dalamaria, Tatiane; Martins, Fernanda Andrade; Höfelmann, Doroteia Aparecida; Crispim, Sandra; Gorgulho, Bartira; Rodrigues, Paulo; Marchioni, Dirce MariaBackground: Diet quality is associated with psychobiological, psychological, biological, and physiological factors of individuals, and in the context of prolonged stress, such as the COVID-19 pandemic, it can lead to a worsening of the quality of food for undergraduates. This study aimed to analyze diet quality and associated factors in Brazilian undergraduates. Methods: Data were collected from 4,799 undergraduate students from all Brazilian regions, from August 2020 to February 2021. The online questionnaire contained socioeconomic variables, the ESQUADA scale to assess diet quality, self-referred changes in weight, the Brazilian food insecurity scale (EBIA), sleep assessment and the perceived stress scale. Unconditional multiple logistic regression analysis was performed to study variables associated with poor and very poor diet quality. Results: Most of participants presented a good diet quality (51.7%), while 9.8% had a poor or very poor diet quality and only 1.1% had an excellent diet quality. 58.2% of undergraduates reported to have an increase in weight during the pandemic and 74.3% of the students presented elevated stress during the pandemic. Logistic regressions showed students who gained weight during the pandemic presented the highest AOR = 1.56 (95% CI = 1.12–2.20) for poor or very poor diet quality. The elevated perceived stress was also associated with a higher AOR = 2.85 (95% CI = 1.71–4.74) for poor or very poor diet quality. Conclusion: Most of the studied undergraduates presented a good diet quality. Nevertheless, poor/very poor diet quality was associated with higher perceived stress and weight gain. Our study indicated that policies should beaimed at the socioeconomically most vulnerable undergraduates, those in a situation of food and nutritional insecurity, high perceived stress, and who gained weight during the pandemicArtigo Food insecurity and associated factors in brazilian undergraduates during the COVID-19 pandemic(Nutrients, 2022) Maciel, Bruna Leal Lima; Lyra, Clélia de Oliveira; Gomes, Jéssica Raissa Carlos; Rolim, Priscilla Moura; Gorgulho, Bartira Mendes; Nogueira, Patrícia Simone; Rodrigues, Paulo Rogério Melo; Silva, Tiago Feitosa da; Martins, Fernanda Andrade; Dalamaria, Tatiane; Santos, Thanise Sabrina Souza; Höfelmann, Doroteia Aparecida; Crispim, Sandra Patrícia; Slater, Betzabeth; Ramalho, Alanderson Alves; Marchioni, Dirce MariaUndergraduates may face challenges to assure food security, related to economic and mental distress, especially during the COVID-19 pandemic. This study aimed to assess food insecurity and its associated factors in undergraduates during the COVID-19 pandemic. An online cross-sectional study was conducted from August 2020 to February 2021 with 4775 undergraduates from all Brazilian regions. The questionnaire contained socio-economic variables, the validated Brazilian food insecurity scale, and the ESQUADA scale to assess diet quality. The median age of the students was 22.0 years, and 48.0% reported income decreasing with the pandemic. Food insecurity was present in 38.6% of the students, 4.5% with severe food insecurity and 7.7% moderate. Logistic regressions showed students with brown and black skin color/race presented the highest OR for food insecurity; both income and weight increase or reduction during the pandemic was also associated with a higher OR for food insecurity, and better diet quality was associated with decreased OR for food insecurity. Our study showed a considerable presence of food insecurity in undergraduates. Policy for this population must be directed to the most vulnerable: those with brown and black skin color/race, who changed income during the pandemic, and those presented with difficulties maintaining weight and with poor diet qualityArtigo Variance sources and ratios to estimate energy and nutrient intakes in a sample of adolescents from public schools, Natal, Brazil(Revista de Nutrição, 2013) Lima, Severina Carla Vieira Cunha; Lyra, Clélia Oliveira; Sena-evangelista, Karine Cavalcanti Maurício; Pinheiro, Liana Galvão Bacurau; Morais, Célia Márcia Medeiros; Slater, Betzabeth; Pedrosa, Lucia Fatima Campos; https://orcid.org/0000-0001-8268-1986Objective: The aim of this study was to describe the sources of dietary variance, and determine the variance ratios and the number of days needed for estimating the habitual diet of adolescents. Methods Two 24 hour food recalls were used for estimating the energy, macronutrient, fatty acid, fiber and cholesterol intakes of 366 adolescents attending Public Schools in Natal, Rio Grande do Norte, Brazil. The variance ratio between the intrapersonal and interpersonal variances, determined by Analysis of Variance, was calculated. The number of days needed for estimating the habitual intake of each nutrient was given by the hypothetical correlation (r)≥0.9 between the actual and observed nutrient intakes.Results Sources of interpersonal variation were higher for all nutrients and in both genders. Variance ratios were <1 for all nutrients and higher in women. Two 24 hour dietary recalls were enough to assess energy, carbohydrate, fiber and saturated and monounsaturated fatty acid intakes accurately. However, the accurate assessment of protein, lipid, polyunsaturated fatty acid and cholesterol intakes required three 24 hour recalls. Conclusion Interpersonal dietary variance in adolescents was greater than intrapersonal variance for all nutrients, resulting in a variance ratio of less than 1. Two to three 24 hour recalls, depending on gender and the study nutrient, are necessary for estimating the habitual diet of this population.Artigo Variance sources and ratios to estimate energy and nutrient intakes in a sample of adolescents from public schools, Natal, Brazil(Revista de Nutrição, 2013-04) Morais, Célia Márcia Medeiros de; Lima, Severina Carla Vieira Cunha; Lyra, Clélia Oliveira; Evangelista, Karine Cavalcanti Maurício Sena; Pineiro, Liana Galvão Bacurau; Slater, Betzabeth; Pedrosa, Lucia Fatima CamposObjective: The aim of this study was to describe the sources of dietary variance, and determine the variance ratios and the number of days needed for estimating the habitual diet of adolescents.
