ABSTRACT
OBJECTIVES: To verify the association between the consumption of red and processed meats and the incidence of hypertension in participants of the Longitudinal Study of Adult Health. METHODS: This was a cohort with data from the baseline (2008-2010) and second wave (2012-2014) with 8,089 public workers of both sexes and different racial groups, with mean age of 49 ± 8 years (35-74 years old). Meat consumption (g/d) was estimated using a food frequency questionnaire and was divided into consumption tertiles. Hypertension was defined as systolic blood pressure ≥140 mm Hg and/or diastolic ≥90 mm Hg and/or antihypertensive medication. Cox proportional hazards models were used to estimate adjusted Hazard Ration (HRs) and 95% confidence interval (CI) for incident hypertension. RESULTS: A total of 1186 incident cases of hypertension were identified. Even adjusting for confounders, such as urinary Na/K (sodium/potassium) ratio and BMI (body mass index), participants in the second (HR:1.19; 95% CI 1.03-1.30) and third (HR:1.30; 95% CI:1.11-1.53) tertile of processed meat consumption had a higher risk of developing hypertension than those in the first tertile. We did not find a significant association between red meat consumption and hypertension. CONCLUSIONS: The increased risk of developing hypertension is associated with moderate and high consumption of processed meats but not with consumption of red meat.
ABSTRACT
BACKGROUND: Anxiety symptoms are factors that directly affect eating habits, but this interference can be heterogeneous depending on the nutritional status of the individuals. OBJECTIVES: To analyze whether the presence of anxiety symptoms at the beginning of the pandemic influenced the change in food consumption according to its purpose and extent of processing during a one-year follow-up and whether this association occurs equally with excess weight and without excess weight university students. METHODS: This longitudinal study was carried out with 583 university students from a public Higher Education Institution (HEI) in Brazil. The Generalized Estimating Equation (GEE) was used to verify whether anxiety symptoms were associated with changes in food consumption over time. RESULTS: The results showed that previous moderate/severe anxiety symptoms were associated with an increased frequency of consumption of both fresh or minimally processed foods (ß: 0.2 95%CI: 0.1; 0.7 p = 0.013) and ultra-processed foods (ß: 5.6 95%CI: 1.8; 17.7 p = 0.003), but with different magnitudes. In university students who were not excess weight, previous moderate/severe anxiety symptoms were associated with a reduction in the frequency of consumption of fresh or minimally processed foods (ß: -2.0 95%CI: -3.5; -0.5 p = 0.008), while in those who were excess weight, there was an increase in consumption of ultra-processed foods (ß: 4.5 95%CI: 2.2; 6.8 p < 0.001). CONCLUSION: This study confirms the influence of anxiety symptoms on food consumption according to the extent and purpose of processing. In addition, these results emphasize the role of psychological distress in the university population, and that this factor can affect excess weight and without excess weight individuals differently.
ABSTRACT
This cross-sectional study, carried out between October and December 2020 in two Brazilian cities, aimed to evaluate the joint association of education and sex with habitual and episodic excessive alcohol consumption during the COVID-19 pandemic. Habitual alcohol consumption was defined as drinking any quantity of alcohol at least once per week. Excessive episodic alcohol consumption was defined as the consumption of five or more drinks by men or four or more drinks by women at least once in the last 30 days. Adjusted multivariate logistic regression models were used to analyze associations of education and sex with alcohol consumption. Education was not associated with habitual alcohol consumption and excessive episodic alcohol consumption. However, when evaluating the joint effect between education and sex, it can be seen that men with low education were more likely to habitually consume (OR: 5.85; CI95:2.74-14.84) and abuse alcohol (OR: 4.45; IC95:1.54-12.82) and women with high education were more likely to have habitual (OR: 2.16; IC95:1.18-3.95) and abusive alcohol consumption (OR: 2.00; IC95:1.16-3.43). These findings highlight the modifying effect of sex on the relationship between education and alcohol consumption, such that education influenced alcohol consumption differently between sexes during the pandemic.

BACKGROUND: Dietary fatty acids are related to the development of several inflammatory-related diseases, which may include depression. So, the association between fatty acids, culinary oils and fat intake and depression in highly educated Brazilians was evaluated. METHODS: Multicenter cross-sectional study using baseline data from the Cohort of Universities of Minas Gerais. The diagnosis of depression was self-reported, and the daily intake of fatty acids was assessed using a 144-item food frequency questionnaire (FFQ). RESULTS: A total of 7157 participants (68.83 % women) with a median age of 33 years were included. The prevalence of depression was 12.60 % (N = 902). In the adjusted analyses, it was observed that individuals with the highest intake of omega-6 fatty acids (n-6) (OR: 1.36, 95 % CI 1.11-1.67) had a higher prevalence of depression. This increased n-6 intake was identified as a risk factor for depression only among male participants, while among overweight participants, higher n-6 intake was also positively associated with depression. Conversely, a higher ratio of polyunsaturated to monounsaturated and saturated fatty acids (PM/S) was also found to be positively associated with depression, but this association was observed only among non-overweight participants. No associations were found between the consumption of culinary oils or fats and depression. LIMITATIONS: Cross-sectional design limits the assessment of causality. The use of the FFQ can make estimates more difficult. CONCLUSION: Higher consumption of n-6, and higher PM/S ratios were associated with depression, and individual factors can interfere. The mental health care policies should include specific nutritional strategies.

A prática de más condutas éticas parece ser rotineira na graduação. Dessa forma, abordar a conduta ética na formação é um ponto de partida para promover o debate sobre a construção do conhecimento. Este estudo teve o objetivo analisar a conduta ética de graduandos em Nutrição. Realizou-se estudo transversal com estudantes de Nutrição de uma universidade pública-Brasil. Participaram 105 alunos: 42,9% eram do 1º ao 5º semestres e 57,1% do 6º ao 9º semestres. Os alunos dos semestres finais apresentaram maior prevalência de "deixar os colegas copiarem as respostas" (p=0,05), "usar trabalhos prontos" (p=0,04) e "incluir nome em trabalho sem colaboração" (p=0,01). As principais motivações para a má conduta ética foram: má conduta dos colegas (71,4%), acreditar que os professores cometeram má conduta ética (70,5%), disciplina difícil (52,4%) e manter boas notas (50,5%). Os alunos dos últimos semestres referiram a falta de tempo (p=0,05) como uma razão, e 10,5% afirmaram ter realizado consultas de nutrição sem supervisão. Dada a elevada prevalência de más condutas éticas na graduação sugere-se que a disciplina sobre ética seja ministrada nos semestres iniciais, além de realização de cursos e rodas de conversa sobre propriedade intelectual, conduta ética, gestão do tempo e metodologias de ensino.
The practice of academic misconduct seems to be routine in undergraduate studies. Therefore, addressing ethical conduct in training is a starting point to promote debate on the construction of knowledge. This study aimed to analyze the academic misconduct of nutrition undergraduates. A cross-sectional study was performed with Nutrition students at a public university in Brazil. Participants included 105 students took part in the study: 42.9% were on the 1st to the 5th semesters and 57.1% on the 6th to the 9th semesters. Students on the final semesters had a higher prevalence of "letting the colleagues copy the answers" (p=0.05), "using ready-made work" (p=0.04), and "included their name on a paper without collaboration" (p=0.01). The main motivations for academic misconduct were: colleagues cheating (71.4%), believing that professors had committed misconduct (70.5%), difficult subjects (52.4%), and maintaining good grades (50.5%). Students on the last semesters reported lack of time (p=0.05) as a reason, and 10.5% mentioned having performed nutrition appointments without supervision. Given the high prevalence of academic misconduct in undergraduate courses, it is suggested that the discipline on ethics be taught in the initial semesters, in addition to offering courses and conversation circles on intellectual property, ethical conduct, time management, and teaching methodologies.
ABSTRACT
OBJECTIVE: The aim of this study is to evaluate the validity and reliability of the Perceived Nutrition Environment Measures Survey (NEMS-P) translated and adapted for use in Brazil. DESIGN: Validation of the NEMS-P questionnaire. The questionnaires were applied to assess validity and reliability, based on exploratory factor analysis, Cronbach's α coefficient and intra-class correlation, with a significance level of 95 %. SETTING: Brazil. PARTICIPANTS: Adults over 20 years of age diagnosed with hypertension were included in the internal validity and reliability test (n 176) and intra-rater reliability (subsample n 35). RESULTS: Factor analysis obtained satisfactory results. Internal consistency was acceptable for most items, with Cronbach's α ranging from 0·6 to 0·9. The intra-rater reliability of the subsample was also valid, with intra-class correlation coefficient values ranging from 0·5 to 0·9. CONCLUSION: This work reveals the usefulness of the instrument to assess the perceived food environment in the Brazilian context, being able to measure what is proposed according to its theoretical model, and reproduces the values when applied to a sample different from its original validation. However, refinement of some questions is suggested. Finally, it demonstrates the possibility of using the entire instrument or each section independently, according to the food environments to be investigated.

We aimed to evaluate the intake of dietary total polyphenols and their classes according to NOVA classification among adults of a Brazilian cohort study. This is a cross-sectional study, in which food consumption was assessed using an Food Frequency Questionnaire (FFQ) and polyphenol content (total and their classes) was estimated at Phenol-Explorer for each food category and presented as mean and 95% confidence interval. Adjusted linear regression was used to describe the trend of the association between the quintiles of polyphenols intake (dependent variable) and NOVA group of food consumption (independent variable). The higher consumption of fresh/minimally processed foods is accompanied by a higher intake of total polyphenols and all their classes, while the higher consumption of ultra-processed foods represented the lower intake of total polyphenols and their classes. Fresh foods are the greatest sources of polyphenols, and their daily consumption should be encouraged, while ultra-processed foods are deficient in such bioactive compounds.

OBJECTIVE: To investigate whether the combined consumption of fresh/minimally processed and ultra-processed food is associated with food insecurity (FI) during the COVID-19 pandemic. DESIGN: Cross-sectional observational study was derived from a survey using a population-based search of a complex sample. FI was assessed using the validated Brazilian Food Insecurity Scale. Food consumption was assessed using a qualitative FFQ and the NOVA classification for fresh/minimally processed food and ultra-processed food. A scoring system was used to evaluate combined food consumption according to the extent and purpose of processing, considering the weekly consumption of the two groups (according to the NOVA classification). Higher punctuation reflects worse diet quality (higher consumption of ultra-processed foods and lower consumption of fresh/minimally processed foods). A theoretical causality model was constructed using a directed acyclic graph, and multivariate analysis was performed using Poisson regression to test the association between FI and food consumption. SETTING: Ouro Preto and Mariana, Brazil, between October and December 2020. PARTICIPANTS: An epidemiological household survey was conducted with 1753 individuals selected through a stratified and clustered sampling design in three stages. RESULTS: Those with food consumption scores in the fourth quartile had a 60 % higher prevalence ratio (PR) for FI (PR: 1·60 and 95 % CI: 1·06 - 2·40). Also, the increased consumption of fresh/minimally processed foods and low consumption of ultra-processed foods presented a 45 % lower prevalence ratio of FI (PR: 0·55 and 95 % CI: 0·40 - 0·80). CONCLUSION: These results indicate an inverse association between FI and diet quality.

Objective:Epidemiological studies have shown associations between polyphenol consumption and reduced risk of cardiovascular diseases. This study aimed to assess the association between polyphenol intake and the prevalence of hypertension.Methods:This cross-sectional study was performed on data from the Cohort of Universities of Minas Gerais (CUME) project. Participants completed an online food frequency questionnaire, and polyphenol intake was assessed using the Phenol-Explorer database and articles. Hypertension was determined by a medical diagnosis, having a blood pressure ≥ 130 mmHg/80 mmHg, or using antihypertensive drugs. Adjusted logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (95% CIs) for the prevalence of hypertension.Results:The prevalence of hypertension was 39.57%, and the average intake of total polyphenols was 860.79 mg/day. The highest (5th quintile) intake of flavonoids (mean: 368.46mg/day; OR: 0.83; 95%CI 0.70; 0.97), hydroxybenzoic acids (mean: 379.38mg/day; OR: 0.77; 95%CI: 0.66;0.91), and flavonols (mean: 44.13mg/day; OR: 0.79; 95%CI: 0.67; 0.93) was inversely associated with hypertension prevalence, compared to the lowest intake (1st quintile).Conclusions:Our findings demonstrate that the intake of flavonoids, hydroxybenzoic acids, and flavonols is associated with a lower prevalence of hypertension.

AIM: To assess the association of food consumption according to degree of processing with changes in systolic (SBP) and diastolic (DBP) blood pressure in adult participants of a Brazilian cohort. METHODS: Longitudinal study with 2496 adult participants of the Cohort of Universities of Minas Gerais (CUME Project). Food consumption was categorized by food groups according to degree of processing following the NOVA grading system: unprocessed/minimally processed foods/culinary ingredients (U/MPF&CI), processed foods (PFs) and ultra-processed foods (UPFs). unprocessed/minimally processed foods/culinary ingredients (U/MPF&CI), processed foods (PFs) and ultra-processed foods (UPFs). Changes in SBP and DBP were categorized (decreased, maintained, increased). Independent associations between exposure and outcomes were verified using multiple generalized ordered logistic models adjusted for potential confounders. RESULTS: After a two-year follow-up, the consumption of U/MPF&CI (% daily caloric intake) reduced the chance of increasing DBP (P for trendâ=â0.014), with a more evident effect among participants within the 5th quintile of this food group (odds ratio (OR)â=â0.55; 95% confidence interval (CI): 0.34-0.97]. On the other hand, the consumption of UPFs (% daily caloric intake) raised the chance of increasing DBP (P for trendâ=â0.005) and was more evident among participants within the quintiles of higher consumption (4th quintile - ORâ=â1.97; 95% CI: 1.25-3.10; 5th quintile - ORâ=â1.79; 95% CIâ=â1.12-2.86). No associations were found between food consumption according to degree of processing and changes in SBP. CONCLUSION: Higher consumption of U/MPF&CI and UPFs were independently associated to lower and greater chances of increased DBP in adult participants from CUME Project.

Introdução: O contexto pandêmico tem implicações diretas na situação de segurança alimentar e nutricional atual e futura, assim é urgente avaliar a situação da insegurança alimentar em suas diferentes dimensões. Há poucos estudos que avaliam conjuntamente segurança alimentar, disponibilidade e acesso aos alimentos. Objetivo: Descrever a disponibilidade alimentar domiciliar e o acesso percebido aos alimentos segundo a situação de insegurança alimentar em domicílios de escolares na pandemia de COVID-19. Métodos: Trata-se de um estudo transversal com amostra representativa de domicílios de escolares da educação infantil e ensino fundamental de escolas públicas de Mariana e Ouro Preto, Minas Gerais. Os dados foram coletados na fase inicial da pandemia, "junho e julho de 2020", por meio de entrevistas telefônicas com os responsáveis por comprar e/ou preparar os alimentos nos domicílios. Investigou-se condições socioeconômicas, acesso percebido aos alimentos, disponibilidade alimentar domiciliar e insegurança alimentar, esta avaliada por meio da Escala Brasileira de Insegurança Alimentar. Resultados: Dos 612 domicílios investigados, 82,0% estavam em situação de insegurança alimentar, sendo 11,3% em insegurança moderada e 5,1% em insegurança grave. Foi observada relação entre disponibilidade de frutas, hortaliças, leite, carnes e ovos com a insegurança alimentar, bem como com a percepção de dificuldade no acesso a frutas e hortaliças. Discussão: A situação de insegurança alimentar enfrentada pelos domicílios relaciona-se com menor disponibilidade de alimentos importantes para o desenvolvimento dos escolares, ademais as famílias depararam com inacessibilidade para adquirir frutas e hortaliças.

Introduction: The pandemic context impacts the current and future situation of food and nutritional security, so it is urgent to assess the situation of food insecurity in its different dimensions. There are few studies that jointly assess food security, availability, and access to food. Objective: To describe household food availability and perceived access to food according to the situation of food insecurity in households of schoolchildren during the COVID-19 pandemic. Methods: This is a cross-sectional study with a representative sample of households of schoolchildren in early childhood education and elementary school from public schools in Mariana and Ouro Preto, Minas Gerais. Data were collected in the initial phase of the pandemic, "June and July 2020", through telephone interviews with those responsible for buying and/or preparing the food in the households. Socioeconomic conditions, perceived access to food, and household food availability were investigated, and food insecurity was measured using the Brazilian Household Food Insecurity Measurement Scale. Results: Of the 612 households surveyed, 82.0% of the households presented food insecurity, of which 11.3% moderate food insecurity and 5.1% severe food insecurity. A relationship was observed between the low availability of fruits, vegetables, milk, meat, and eggs with food insecurity and the perception of difficulty in accessing fruits and vegetables. Discussion: The situation of food insecurity faced by households is related to low availability of essential foods for the development of schoolchildren, and families also encounter inaccessibility to acquire fruits and vegetables.

ABSTRACT
Background and aim: The growing increase in diet- and behavior-related illnesses has drawn the attention of many epidemiologists who attribute such changes to the epidemiological and nutritional transition. Thus, this study aims to evaluate the association between the combined occurrence of health risk behaviors, such as sedentary lifestyles, high weekly consumption of ultra-processed foods (UPFs), and non-daily consumption of fruits and vegetables, and symptoms of anxiety or depression in adults. Methods: This is a cross-sectional study based on an epidemiological survey in two Brazilian cities. The outcome, anxiety, and depression symptoms were assessed using the Generalized Anxiety Disorder 7-item (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9). Food consumption was assessed using a qualitative food frequency questionnaire (FFQ) with reference to consumption in the last 3 months and categorized into the consumption of fruits and vegetables and the consumption of UPFs according to the NOVA classification. Sedentary behavior was assessed by considering the amount of sitting or reclining time per day reported by participants and categorized as less than 9 h of sitting or reclining and 9 h or more. For the analysis, adjusted Poisson regression (PR) was used to estimate the prevalence ratio and the 95% confidence interval (CI). Results: Those with the health risk behaviors, non-daily consumption of fruits and vegetables, and high consumption of UPFs had a 2.6 higher prevalence ratio for symptoms of mental disorder (PR: 2.6 and 95%CI: 1.1-6.5), as well as those with all three health risk behaviors, had a 2.8 higher prevalence ratio for symptoms of mental disorder (PR: 2.8 and 95%CI: 1.3-6.1). Conclusion: This study revealed that the existence of a combination of two and three health risk behaviors led to a higher prevalence of symptoms of anxiety or depression.
ABSTRACT
BACKGROUND AND AIMS: Consumption of ultra-processed foods is negatively associated with health outcomes, however, the contribution to sleep quality is limited. Therefore, the objective of this study was to evaluate the association between food intake by frequency and degree of processing and sleep quality in adults during the covid-19 pandemic. METHODS: Population-based survey of adults from October to December 2020 in the Iron Quadrangle region, Brazil. The exposure variable was a food intake score that considered the frequency of consumption and food processing degree. The total score ranged from 0 (best) to 48 points (worst food quality), categorized into quartiles. Furthermore, we also evaluated whether individuals replaced their lunch and/or dinner based mostly on fresh/minimally processed foods for ultra-processed foods, for five or more days in the week. The outcome variable was sleep quality assessed with the Pittsburgh Sleep Quality Index. We constructed a contrasting directed acyclic graph (DAG) model to estimate the adjusted odds ratio of the association between score eating and sleep, by logistic regression. RESULTS: Most of the 1762 individuals evaluated had poor sleep quality (52.5%). The minimum and maximum food scores were 0 and 30 points (mean 9.16; 95% CI 8.50, 9.81). The higher values of the score corresponded to lower consumption of fresh and minimally processed foods and higher consumption of ultraprocessed foods. In multivariate analysis, individuals in the third food consumption score had 71% greater odds of poor sleep quality (OR = 1.71; 95% CI: 1.03, 2.85) and in the fourth quartile 144% greater odds (OR = 2.44; 95% CI: 1.32, 2.44). Besides, replacing the dinner meal with ultra-processed foods five days or more in the week was also associated with poor sleep quality (OR = 2.01; 95%CI: 1.14, 3.57). CONCLUSION: Higher consumption of ultra-processed foods concomitant with lower consumption of fresh and minimally processed foods is associated with a higher chance of poor sleep quality.

BACKGROUND & AIM: Psychological disorders are an important health problem worldwide. A healthy diet is recommended as one of the measures to prevent and control mental disorders. Epidemiological studies have shown important associations between the consumption of diets rich in nutrients and a lower risk of developing anxiety and depression. Therefore, the aim of this study was to evaluate the association between the prevalence of anxiety and depression symptoms and food consumption, according to the degree of processing, during the COVID-19 pandemic. METHODS: An epidemiological household survey was conducted in two cities in Brazil. Anxiety and depression symptoms were assessed using validated scales (Generalized Anxiety Disorder 7-item/Patient Health Questionnaire-9), and food consumption was assessed using a qualitative food frequency questionnaire referring to consumption within the last 3 months. The foods were categorized according to the NOVA classification for fresh/minimally processed food and ultra-processed food, using the average weekly consumption as the cutoff. For data analysis, adjusted Poisson regression with robust variance was utilized to estimate the prevalence ratio and 95% confidence interval (CI). RESULTS: The consumption of fresh/minimally processed foods above the weekly average frequency was associated with a lower prevalence of symptoms of depression (PR: 0.5, 95% CI: 0.3; 0.7). Consumption above the weekly average of ultra-processed foods was associated with a higher prevalence of anxiety (PR: 1.5 and 95% CI: 1.03; 2.3) and depression symptoms (PR: 1.5, 95% CI: 1.0; 2.1, P = 0.034). CONCLUSION: Increased consumption of ultra-processed foods is associated with a higher occurrence of anxiety and depression symptoms; therefore, we recommend an increase in the consumption of fresh/minimally processed foods, as endorsed by the Dietary Guidelines for the Brazilian Population.

OBJECTIVES: We sought to evaluate the effect of socioeconomic conditions and variables related to the COVID-19 pandemic on the food insecurity of students during suspension of classes in public schools. METHODS: This was a telephone survey (n = 612) of adults responsible for purchasing food through representative samples of students in two Brazilian municipalities in June and July 2020. The outcome was food insecurity, assessed using the Brazilian Food Insecurity Scale. Multivariate logistic regression models were used to estimate the odds ratio (OR) and 95% confidence interval (CIs) for sociodemographic and pandemic-related factors of COVID-19. RESULTS: The total prevalence of food insecurity in households was 82%, with 65.7% mild food insecurity, 11.3% moderate, and 5.0% severe. After adjustment for confounding factors, households with the highest number of children (OR = 2.17; 95% CI, 1.10-4.27) and households that received local-government basic food baskets (OR = 1.64; 95% CI, 1.04-2.58) were significantly associated with food insecurity. Furthermore, households that did not experience a decrease in income during the pandemic were inversely associated with food insecurity (OR, 0.17; 95% CI, 0.09-0.32). CONCLUSIONS: The prevalence of food insecurity was high, and policies for the distribution of food baskets may not be sufficient to guarantee food security for the most vulnerable families with a greater number of children. Considering the possible worsening of food insecurity during the COVID-19 pandemic, the National School Feeding Program has the potential to play a strategic role in promoting food security for students.

OBJECTIVE: To evaluate the effectiveness of a nutritional intervention to promote fruit and vegetable (FV) intake. DESIGN: A randomised controlled community trial was conducted to evaluate the effectiveness of a 7-month nutritional intervention and to promote FV intake, separately and together. All participants attended physical exercise sessions. The intervention was based on the transtheoretical model and Paulo Freire's pedagogy. The interventions included group educational sessions, motivational cards and informational materials. The primary outcome was a change in FV intake (g/d), and secondary outcomes included stages of change, self-efficacy, decisional balance and knowledge on FV. All data were collected face-to-face; and FV intake was assessed using a validated brief questionnaire. SETTING: Health promotion services of Brazilian Primary Health Care. PARTICIPANTS: 3414 users of Brazilian Primary Health Care (1931 in the control group and 1483 in the intervention group (IG)). RESULTS: At baseline, the average daily FV intake was 370·4 g/d (95 % CI 364·2, 376·6). The increase in FV intake (23·4 g/d; 95 % CI 6·7, 40·0) and fruit intake (+17·3 g/d; 95 % CI 5·1, 29·4; P = 0·01) was greater in the IG among participants in the lowest baseline intake. Participants in the IG also showed progression in the stages of change (P < 0·001), increased self-efficacy (P < 0·001) and improved knowledge of FV crops (P < 0·001). CONCLUSIONS: The nutritional intervention was effective in increasing FV intake and fruits intake among individuals with a lower intake at baseline and in maintaining FV intake among those who reported consuming FV as recommended (400 g/d).

The study aimed to prospectively examine the association between different sedentary behaviors and the risk of depression. We included 12,691 Spanish university graduates (mean age: 36.7 year; SD: 11.5), participants of the Seguimiento Universidad de Navarra cohort (the SUN Project), initially free of depression who were followed-up for a median of 10.9 years. Based on items presented in our baseline questionnaire, time spent in four sedentary behaviors (hours/day) were evaluated: overall sitting time; TV-viewing; computer use; and driving. Participants were classified as incident cases of depression if they reported a physician diagnosis of depression in at least one of the follow-up assessments conducted after the first two years of follow-up. Cox regression models were used to assess the relationship between sedentary behaviors and depression. A total of 560 incident cases of depression were identified during follow-up. We found no significant association between overall sitting time, TV-viewing or driving and risk of depression. On the other hand, computer use was directly associated with the risk of developing depression during the follow-up (p-value for trend = 0.020), with the participants in the highest quartile of computer use (3.64 to 10 hours/week) having a higher risk of developing depression (HR = 1.33; 95%CI: 1.05-1.70) than those in the lowest quartile (0 to 0.25 hours/week) after adjusting for potential confounders. Prolonged use of computer was independently associated with an increased risk of developing depression among young middle-aged adult university graduates from a Spanish cohort.
El objetivo del estudio fue examinar prospectivamente la asociación entre diferentes comportamientos sedentarios y el riesgo de depresión. Incluimos a 12.691 graduados universitarios españoles (media de edad: 36,7 años; SD: 11,5), participantes en la cohorte de Seguimiento Universidad de Navarra (Proyecto SUN), que no sufrieran depresión inicialmente y a quienes se les realizó un seguimiento durante una mediana de 10.9 años. Basados en los ítems presentados en nuestro cuestionario de línea de base, se evaluó el tiempo transcurrido con cuatro comportamientos sedentarios (horas/día): tiempo sentado en general, tiempo viendo TV, usando el ordenador, y conduciendo. Los participantes se clasificaron como casos incidentes de depresión, si informaban de un diagnóstico médico de depresión, emitido por un doctor en al menos una de las evaluaciones de seguimiento llevadas a cabo tras los dos primeros años de seguimiento. Los modelos de regresión Cox se usaron para evaluar la relación entre comportamientos sedentarios y depresión. Se identificaron un total de 560 casos incidentes de depresión durante el seguimiento. No encontramos ninguna asociación significativa entre el tiempo sentado en general, tiempo viendo TV, o conduciendo y el riesgo de depresión. Por otro lado, el uso del ordenador estuvo directamente asociado con el riesgo de desarrollar depresión durante el seguimiento (valor de p para tendencia = 0,020), con los participantes en el cuartil más alto de uso del ordenador (3,64 a 10 horas/semana) teniendo un riesgo más alto de desarrollar depresión (HR = 1,33; IC95%: 1,05-1,70), respecto a quienes estaban en el cuartil más bajo (0 a 0,25 horas/semana) tras realizar un ajuste para potenciales factores de confusión. El uso prolongado del ordenador estuvo independientemente asociado con el mayor riesgo de desarrollar depresión entre adultos jóvenes de mediana edad, graduados universitarios, procedentes de una cohorte española.
O estudo buscou examinar prospectivamente a associação entre diversos comportamentos sedentários e risco de depressão. Incluímos 12.691 indivíduos espanhóis com nível universitário (média de idade: 36,7 anos; DP: 11,5), participantes da coorte Seguimiento Universidad de Navarra (Projeto SUN), inicialmente sem depressão, que foram seguidos por uma mediana de 10,9 anos. Com base nos itens apresentados no questionário da linha de base, foram avaliados os tempos gastos em quatro comportamentos sedentários (horas/dia): total de tempo sentado e tempo assistindo televisão, usando computador e dirigindo. Os participantes eram classificados como casos incidentes de depressão quando relatavam um diagnóstico de depressão feito por médico em pelo menos uma das avaliações de seguimento após os primeiros dois anos de seguimento. Foram usados modelos de regressão Cox para avaliar a relação entre comportamentos sedentários e depressão. Foram identificados 560 casos incidentes de depressão durante o seguimento. Não encontramos associação entre total de tempo sentado, tempo assistindo TV ou dirigindo e risco de depressão. Por outro lado, o uso de computador mostrou associação direta com o risco de desenvolver depressão durante o seguimento (valor de p para tendência = 0,020), no qual os participantes no quartil mais alto de uso de computador (entre 3,64 e 10 horas/semana) tiveram o risco maior de desenvolver depressão (HR = 1,33; IC95%: 1,05-1,70) comparados com aqueles no quartil mais baixo (0 a 0,25 horas/semana), depois de ajustar para potenciais fatores de confusão. O uso prolongado do computador esteve associado de maneira independente com risco aumentado de desenvolver depressão em adultos de meia idade com nível universitário em uma coorte espanhola.
ABSTRACT
ABSTRACT Objective To evaluate factors associated with dietary practices in students of a institution of higher education, included in the PADu study: "Anxiety and depression symptoms among university students in Minas Gerais: a longitudinal study". Methods Cross-sectional study of PADu project baseline with undergraduate first period students, who responded in person to a printed and self-administered questionnaire. Dietary practices were evaluated through a 24 items scale based on recommendations of Dietary Guidelines for the Brazilian Population. Answer choices are four-point Likert scale: "strongly agree", "agree", "disagree" and "strongly disagree". The sum of the items corresponded a score ranging (0-72 points), a high score indicating greater adequacy. The explanatory variables were: sociodemographics (gender, age, knowledge area, skin color, marital status, monthly household income), behaviors (excess alcohol consumption, physical exercise, screen exposure, internet use), health conditions (self-rated health, nutritional status, symptoms of depression, anxiety, stress). Adjusted multiple linear regression model was used to estimate the coefficients and their 95% CI. Results 356 students participated in the study. The average of dietary practices was 34.9±9.3 (0-63) points. Physical exercise practice (β: 3.75; CI: 1.83; 5.67) was associated with higher scores in the eating students score. We observed factors associated with the lowest score greater exposure to screens (β: -0.44; CI: -0.67; -0.13), excessive internet use (β: -3.05; CI: -5.22; -0.88), poor health self-assessment (β: -3.63; CI: -4.97; -1.21), excessive alcohol consumption (β: -2.09; CI: -3.92;-0.26) and stress symptoms (β: -2.81; CI: -4.72; -0.77). Conclusion Most students have inadequate dietary practices associated with internet use, alcohol consumption and stress.
RESUMO Objetivo Avaliar os fatores associados às práticas alimentares em estudantes de uma instituição de Ensino Superior incluídos no estudo PADu: "Sintomas de ansiedade e depressão em universitários de Minas Gerais: um estudo longitudinal". Métodos Estudo transversal da linha de base do projeto PADu com alunos do primeiro período da graduação, que responderam pessoalmente a um questionário impresso e autoaplicável. As práticas alimentares desses estudantes foram avaliadas por meio de uma escala de 24 itens baseada nas recomendações do Guia Alimentar para a População Brasileira. As opções de resposta foram coletadas em escala Likert de quatro pontos: "concordo totalmente", "concordo", "discordo" e "discordo totalmente". A soma dos itens correspondeu a uma pontuação (0-72 pontos), onde uma pontuação alta indicava maior adequação. As variáveis explicativas foram: características sociodemográficas (sexo, idade, área do conhecimento, cor da pele, estado civil, renda familiar total mensal), comportamentos (consumo excessivo de álcool, exercícios físicos, exposição a telas e uso de internet) e condições de saúde (autoavaliação saúde, estado nutricional, sintomas de depressão, ansiedade e stress). O modelo de regressão linear múltipla ajustado foi usado para estimar os coeficientes e seus IC 95%. Resultados 356 alunos participaram do estudo. A média das práticas alimentares foi de 34,9±9,3 (0-63) pontos. A prática de exercícios físicos (β: 3,75; IC: 1,83; 5,67) esteve associada a maiores escores no escore de hábitos alimentares dos escolares. Foram observados fatores associados ao menor escore maior exposição a telas (β: -0,44; IC: -0,67; -0,13), uso excessivo de internet (β: -3,05; IC: -5,22; -0,88), ruim autoavaliação de saúde (β: -3,63; IC: -4,97; -1,21), consumo excessivo de álcool (β: -2,09; IC: -3,92; -0,26) e sintomas de estresse (β: -2,81; IC: -4,72; -0,77). Conclusão A maioria dos estudantes apresenta práticas alimentares inadequadas associadas ao uso da internet, consumo de álcool e estresse.
