Sociodemographic determinants of eating patterns in two Latin American populations.

BACKGROUND: The present study aimed to describe the dietary patterns of a population from Brazil and another from Colombia with respect to understanding their determinants, similarities and differences. METHODS: An analytical cross-sectional study was conducted based on secondary data. The dietary patterns of the adult population of Pernambuco, Brazil, as well as those of the adult population of Antioquia, Colombia, were analysed using principal component analysis method with orthogonal varimax rotation, and a Poisson regression with robust variance was used to verify the association between eating patterns and socio-economic variables. RESULTS: In each population, three eating patterns were identified. One of them related to healthy eating, named "Prudent", was identified in the two populations analysed. In Pernambuco, a food pattern consisting exclusively of foods with some degree of processing was verified, entitled "Processed". The food culture was reflected in the pattern called "Traditional-Regional" in Pernambuco and the "Traditional" and "Regional" patterns in Antioquia. CONCLUSIONS: Income, education, age, family size, food security status and area of residence were presented as determinants of dietary patterns in both populations. Elements of the food transition were found, which seems to have happened more rapidly in Pernambuco. The food groups that make up the dietary patterns of each population are similar, but the foods that constitute them present differences due to their availability depending on aspects such as climate, soil quality, access to water, local culture and food tradition.

Consumption of in natura and ultra-processed foods in adults: an analysis of social, metabolic, and lifestyle determinants.

OBJECTIVE: To assess the social, metabolic, and lifestyle determinants of consumption of fruits, vegetables, and greens (FVG) and ultra-processed food (ULT) in adults from Pernambuco. METHODS: Cross-sectional and analytical study, conducted in 2015/2016. In addition to sociodemographic variables, the determinants of lifestyle were level of physical activity, alcohol consumption, tobacco use, and metabolic variables were self-reported hypertension, blood glucose, and Body Mass Index (BMI). Consumption was measured by the Food Frequency Questionnaire, then created the Frequency of Consumption Index (SFI) of the mean intake of ULT and FVG foods. The indices of FVG and ULT consumption were transformed into quartiles and these variables were included in the multinomial logistic regression, considering their determinants when p<0.05. RESULTS: The sample was representative of the state, with 1,067 people being interviewed, whose intake of ULT was higher than that of FVG in the lowest and highest quartile of the consumption index. Consumption of fruit and vegetables was higher in higher consumption of alcoholic beverages (p=0.031) and BMI>25 kg/m2 (p=0.047); and lower in the lowest income (p=0.001). ULT intake was higher in young adults (p=0.005), lower income (p=0.044), and controlled blood glucose (p=0.021). Rural areas were 52% less exposed to medium-high ULT consumption (p<0.006). CONCLUSION: Higher rate of ULT consumption in relation to fresh foods, with income as a common determinant, inversely associated with ULT intake and directly related to FVG, which demands structuring policies.

Influence of food environment on ultra-processed drinks consumption among an economically vulnerable population in a metropolitan area in Brazil: A multilevel analysis.

Ultra-processed drinks (UPDs) consumption is increasing, and this intake has been associated with the risk of illness and death. Data on individuals (n = 430) and food stores (n = 231) were collected in an economically vulnerable area in Recife-Brazil, and multilevel regression models were applied to assess the association between UPDs consumption with food environment characteristics. The results show 29.5% of individuals consume UPDs, higher UPD consumption was significantly associated with age (OR: 0.96), lower educational levels (OR:2.06), high density of stores predominantly selling UPFs (OR:2.34) and lower availability of FV in stores (OR:0.49). The applied methodology can inform food environment interventions to reduce UPDs consumption.

Birth-related and current factors associated with physical inactivity in the leisure time in Brazilian adolescents.

BACKGROUND: To determine whether biological and sociodemographic factors at birth and current factors are associated with insufficient physical activity during leisure among Brazilian adolescents. METHODS: A school-based cross-sectional study with national coverage was conducted involving Brazilian adolescents 12 to 17 years of age in municipalities with more than 100 thousand residents. The sample consisted of 74,589 adolescents who participated in the Study of Cardiovascular Risk in Adolescents. Insufficient leisure-time physical activity was categorized based on total volume (<300 minutes/week = insufficiently active; >300 minutes/week = sufficiently active). Poisson regression models were used to assess associated factors. RESULTS: Most adolescents were classified as insufficiently active (54.8%; 95%CI: 53.7-55.9). The variables associated with insufficient physical activity during leisure were the female sex (70.4%; 95%CI: 68.8-71.9), age between 15 and 17 years (57.8%; 95%CI: 56.3-59.2), pertaining to the low or middle class (54.5%; 95%CI: 52.8-56.1), and not being overweight (55.9%; 95%CI: 54.6-57.1). CONCLUSION: Contrary to our hypothesis, birth related factors (e.g., low birth weight, preterm birth and exclusive breastfeeding until 6 months of age) are not associated with physical inactivity. The prevalence of insufficient physical activity during leisure was high among the adolescents evaluated and was associated with sociodemographic characteristics as well as nutritional status. It is necessary to implement strategies focused on physical activity at schools.

Independent predictors of insulin resistance in Brazilian adolescents: Results of the study of cardiovascular risk in adolescents-Brazil.

Considering the current changes in dietary patterns and the increasing prevalence of excess weight throughout the world, several studies have reported insulin resistance, which is a key driver of many chronic diseases, to be an important public health problem in all age groups. Therefore, the aim of the present study was to identify the prevalence and independent predictors of insulin resistance in Brazilian adolescents. A cross-sectional study was conducted with a probabilistic, representative sample of Brazilian adolescents (n = 37,023) who participated in the Study of Cardiovascular Risk in Adolescents. Data were collected on demographic, socioeconomic, lifestyle, anthropometric, and biochemical characteristics as well as antioxidant micronutrient intake (vitamins A, C, E, zinc, and selenium). Insulin resistance was determined using the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) and classified based on the 75th percentile of the sample distribution. Insulin resistance was detected in 27% of the adolescents and was more prevalent among those aged 12 to 14 years (PR: 1.26 [95%CI: 1.13;1.41]), those residing in the southern and south-eastern regions of the country (PR: 1.47 [95%CI: 1.27;1.70]), those who were physically inactive (PR: 1.12 [95%CI: 1.02;1.23]), and those did not consume alcohol (PR: 1.50 [95%CI: 1.13;1.99]). The prevalence of insulin resistance was 2.5-fold higher among individuals with severe obesity (PR: 2.49 [95%CI: 2.07;3.00]). Waist circumference indicative of cardiovascular risk and high serum triglyceride levels increased the likelihood of insulin resistance (PR: 1.37 [95%CI: 1.19;1.59] and 1.60 [95%CI: 1.45;1.78], respectively). The prevalence of the outcome was higher among adolescents in the lower quartiles of vitamin E intake (p<0.05). In the present study, the prevalence of insulin resistance was high among Brazilian adolescents and we identified sociodemographic, lifestyle, anthropometric, biochemical, and dietary predictors of this outcome.

[Lifestyle of adolescent students from public and private schools in Recife: ERICA]. / Estilo de vida de adolescentes estudantes de escolas públicas e privadas em Recife: ERICA.

This study analyzes the behavior patterns related to the lifestyle of adolescents in Recife, Brazil. A cross-sectional study was conducted with data from the Cardiovascular Risk Study among Adolescents (ERICA) and 2400 students aged 12 to 17 were interviewed. The prevalence of physical activity, eating behavior, smoking and alcohol consumption were analyzed. The Chi-square test and 95% confidence interval (95%CI) were used to evaluate the statistical significance of the measurements. It was observed that 60% of the adolescents presented inadequate eating behaviors regarding the consumption of breakfast, daily water intake and meals eaten in front of the TV. About 40% (95%CI: 39.7-45) did not sit down to meals with their parents or guardians. The prevalence of physical inactivity was 52.4% (95%CI: 50-55). Female adolescents were more inactive (68.7%, 95%CI: 65-72) than males (36.4%, 95%CI: 33-40). Teenagers of economic classes D and E were the most inactive (60.7%, 95%CI: 46-73). Alcohol consumption was 18.7% (95%CI: 2.6-5.6) and smoking was prevalent in 3.8% (95%CI: 2-6) of the individuals. Inadequate eating behaviors and physical inactivity were the main areas responsible for an unhealthy lifestyle, followed by alcohol consumption and smoking.

Este estudo analisa os comportamentos relacionados ao estilo de vida de adolescentes em Recife, Brasil. Estudo transversal com dados do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA). 2.400 estudantes de 12 a 17 anos foram entrevistados. Foram analisadas as prevalências de atividade física, comportamento alimentar, tabagismo e consumo de álcool. O teste Qui-quadrado e Intervalo de confiança 95% (IC95%) foram usados para avaliar a significância estatística das medidas. Observou-se 60% dos adolescentes com comportamentos alimentares inadequados quanto ao consumo de café da manhã, água/dia e refeições em frente à TV. Cerca de 40% (IC95%: 39,7-45) não realizavam refeições com os pais ou responsáveis. A prevalência de inatividade física foi de 52,4% (IC95%: 50-55). Adolescentes do sexo feminino foram mais inativas (68,7%; IC95%: 65-72) em relação aos meninos (36,4%; IC95%: 33-40). Adolescentes das classes econômicas D e E foram os mais inativos (60,7%; IC95%: 46-73). O consumo de bebida alcoólica foi de 18,7% (IC95%: 2,6-5,6) e o tabagismo foi de 3,8% (IC95%: 2-6) dos indivíduos. Comportamentos alimentares inadequados e a inatividade física foram os principais domínios responsáveis por um estilo de vida não saudável, seguidos pelo consumo de álcool e tabagismo.

Excess weight in adolescents and associated factors: data from the ERICA study.

OBJECTIVE: To estimate the prevalence of excessive weight and to identify associations with socioeconomic, demographic, biological, and lifestyle factors in adolescents. METHODS: It is a cross-sectional school-based study, with a stratified and complex sample. The evaluated individuals were adolescents (2404), aged 12-17 years old, participating in the Study of Cardiovascular Risk Factors in Adolescents (ERICA). Demographic, socioeconomic, biological, anthropometric, and lifestyle variables were assessed. Poisson regression was used to verify the association between excess weight and independent variables. RESULTS: The prevalence of excessive weight was 26.3% in the study population, being 16.3% for overweight and 10% for obesity. In the multivariate analysis (hierarchical model), were associated with excessive weight: private education network, a higher number of televisions in the residence, eating habits related to the breakfast consumption, snacks purchase in the canteen, snacks in front to screens consumption and consumption of carbohydrates and lipids, in addition to age group (12-14 years) and sexual maturation (post-pubertal). CONCLUSIONS: The prevalence of excessive weight among the school adolescents studied is high, with a value higher than the national average and the results of previous studies with adolescents. Its distribution is associated with different factors, which are socioeconomic, demographic, biological, and related to lifestyle, reinforcing the complexity of this condition, which deserves a broad coping approach, involving not only individual efforts but social and public ones as well.

BIRTH WEIGHT AND OVERWEIGHT IN ADOLESCENTS: THE ERICA PROJECT IN THE CITY OF RECIFE, PERNAMBUCO.

OBJECTIVE: To verify the association of anthropometric parameters at birth, socioeconomic and biological variables, physical activity, and parental nutritional status with overweight and abdominal obesity in adolescents. METHODS: A cross-sectional study was carried out on 39 public and private schools in Recife (state of Pernambuco, Brazil). The sample consisted of 1,081 teenagers aged from 12 to 17 years. Data were collected from the Study of Cardiovascular Risks in Adolescents (ERICA). Body mass index according to age (BMI-for-age), waist circumference (WC), and waist-to-height ratio (WtHR) were considered as outcome variables, whereas the explanatory variables were birth weight, Röhrer's Ponderal Index (RPI), biological and socioeconomic variables, physical activity, and parental nutritional status. The crude and adjusted prevalence ratios (PR) for the studied association were estimated by Poisson Regression. RESULTS: The multivariate Poisson regression showed that the variable that remained significantly associated with overweight in adolescence was maternal overweight, PR=1.86 (95% confidence interval [95%CI] 1.09-3.17). High birth weight also remained significantly associated with abdominal obesity assessed by WC, PR=3.25 (95%CI 1.0-9.74). CONCLUSIONS: High birth weight may be a marker for abdominal obesity in adolescence; and high maternal BMI, for overweight.

[Perception of body weight above the ideal, anthropometric profile and lifestyle among adolescents in the city of Recife, Brazil]. / Percepção do peso corporal acima do ideal, perfil antropométrico e estilo de vida em adolescentes de Recife, PE, Brasil.

This study investigated the perception of above ideal body weight among adolescents in the city of Recife, Brazil, and its association with anthropometric profile and lifestyle. A cross-sectional study was conducted with a sample of 2480 adolescents from the "Study of Cardiovascular Risks in Adolescents." The conceptual model also assessed demographic and socioeconomic variables. Body weight perception was analyzed by asking the question: "In your opinion, your current body weight is … ?" Answers included: below ideal, ideal and above ideal body weight. Statistics were identified using Poisson Regression analysis. The mean age was 14.7 years (SD = 1.6), 53.7% were female, and 70.7% were eutrophic according to the body mass index/age (BMI/A). Perception of body weight was answered by 48.8% of the adolescents. 36.8% and 63.2% saw themselves as below and above their ideal weight, respectively. After adjustments, the variables associated with the perception of body weight above the ideal (outcome variable) were the female sex, age 12 to 14 years, mother's schooling > 8 years, BMI/A in the ideal range, being postpubescent, having breakfast and meals with parents occasionally. Demographic, anthropometric and lifestyle variables were more likely to be associated with body weight perception above the ideal.

O objetivo da pesquisa foi analisar a percepção do peso corporal acima do ideal em adolescentes de Recife/PE e sua associação com o perfil antropométrico e estilo de vida. Trata-se de um estudo transversal com 2.480 escolares participantes do Estudo de Riscos Cardiovasculares em Adolescentes (Erica). O modelo conceitual também considerou variáveis demográficas e socioeconômicas. A percepção do peso foi analisada por meio da pergunta "Na sua opinião o seu peso atual é?", sendo as respostas: "abaixo do ideal", "ideal" e "acima do ideal". As associações foram identificadas por meio da regressão de Poisson. A média da idade foi de 14,7 anos (DP = 1,6), 53,7% eram do sexo feminino e 70,7% eram eutróficos, de acordo com o índice de massa corporal/idade (IMC/I). A percepção do peso foi respondida por 48,8% dos adolescentes. Desses, 36,8% e 63,2% se percebiam com baixo peso e peso acima do ideal, respectivamente. Após os ajustes, as variáveis associadas à percepção do peso acima do ideal foram: sexo feminino, idade entre 12 e 14 anos, escolaridade materna maior que oito anos, IMC/I de eutrofia e de excesso de peso, estágio pós-púbere e realização de café da manhã e refeição com os pais ocasionalmente. Portanto, variáveis demográficas, antropométricas e do estilo de vida se associaram à maior chance de percepção do peso corporal acima do ideal.

Government strategies to ensure the human right to adequate and healthy food facing the Covid-19 pandemic in Brazil. / Estratégias governamentais para a garantia do direito humano à alimentação adequada e saudável no enfrentamento à pandemia de Covid-19 no Brasil.

The Covid-19 pandemic revealed a concrete and immediate threat to food and nutrition security (FNS), especially for vulnerable groups. This study aimed to identify government strategies implemented in Brazil to provide the Human Right to Adequate and Healthy Food in high social vulnerability contexts during the Covid-19 pandemic. A cross-sectional study was carried out, with analysis of official documents published between March 20 and July 30, 2020, by the Federal Government, Federal District, Brazilian states, and capitals, focusing on measures to ensure availability and physical or financial access to food. Strategies implemented mainly involve food distribution and minimum income assurance. The following were implemented: Basic Emergency Income (Federal Government); Food Acquisition Program (PAA), and emergency financial aid (states); emergency food donation programs (states and municipalities). Existing measures were adapted to the pandemic, such as the National School Food Program (PNAE), the National Food Acquisition Program (PAA), and the distribution of food and staple food baskets. While essential, these strategies have limited scope and are insufficient to ensure FNS.

A pandemia de Covid-19 revelou a existência de ameaça concreta e imediata à segurança alimentar e nutricional (SAN), em especial de grupos vulnerabilizados. O estudo buscou identificar as estratégias governamentais implementadas no Brasil para prover o Direito Humano à Alimentação Adequada e Saudável em contextos de elevada vulnerabilidade social frente à Covid-19. Foi realizado um estudo transversal, com análise de documentos oficiais publicados entre 20 de março e 30 de julho de 2020 pela União, Distrito Federal, estados e capitais brasileiras, com foco em medidas que assegurem disponibilidade e acesso físico ou financeiro a alimentos. As estratégias implementadas envolvem fundamentalmente distribuição de alimentos e garantia de renda mínima. Foram instituídas: Renda Básica Emergencial (União); Programa de Aquisição de Alimentos (PAA) e auxílio financeiro emergencial (estados); programas de doação emergencial de alimentos (estados e municípios). Medidas existentes foram adaptadas frente à pandemia, como o Programa Nacional de Alimentação Escolar (PNAE), o Programa de Aquisição de Alimentos (PAA) nacional, a distribuição de alimentos e de cestas básicas. Embora importantes, essas estratégias têm alcance limitado e são insuficientes para assegurar a SAN.

Severity of obesity is associated with worse cardiometabolic risk profile in adolescents: Findings from a Brazilian national study (ERICA).

OBJECTIVE: The prevalence of obesity and severe obesity among adolescents has increased dramatically in developing countries. However, the distribution of cardiometabolic risk factors through the severity of obesity continuum is relatively unknown among youth. The aim of this study was to evaluate the association of weight categories with cardiometabolic risk factors among Brazilian adolescents. METHODS: ERICA (The Study of Cardiovascular Risk in Adolescents) was a multicenter, school-based, cross-sectional study composed of Brazilian adolescents (12-17 y of age). Severity of obesity was classified according to the International Obesity Task Force reference values for body mass index (BMI) and several cardiometabolic risk factors were measured after clinical and biochemical exams and categorized using standard definitions of abnormal values. RESULTS: Among the 37 892 adolescents enrolled, 8708 had excess weight, being classified with overweight (17.2%), obesity (5.6%), and severe obesity (1.3%). Increasing severity of obesity was associated with a worse cardiometabolic profile in the overall sample. Multivariable models that controlled for age, sex, skin color, socioeconomic status, physical activity, and total energy intake, showed that individuals in higher categories of severity of obesity tended to have higher prevalence ratios of most cardiometabolic risk factors compared with the other weight groups, except for high fasting blood glucose among boys. CONCLUSIONS: Progressive degrees of excess weight are positively associated with cardiometabolic risk factors in youth from a middle-income country, indicating the importance in classifying the severity of weight excess among adolescents and considering this to plan prevention programs against early development of obesity-related diseases.

PREVALENCE OF INSULIN RESISTANCE AND ASSOCIATION WITH METABOLIC RISK FACTORS AND FOOD CONSUMPTION IN ADOLESCENTS - RECIFE/BRAZIL.

OBJECTIVE: To identify the prevalence of insulin resistance in adolescents and its associations with metabolic factors and food intake. METHODS: Cross-sectional study conducted with a stratified, complex, school-based sample. The subjects were adolescents (n=1,081) who participated in the Study of Cardiovascular Risk in Adolescents in the city of Recife (Pernambuco, Brazil). We analyzed demographic, socioeconomic, behavioral, anthropometric, biochemical, and dietary variables. Insulin resistance was defined as HOMA-IR>75th percentile. A Poisson multivariate regression model with robust variance adjustment was used, and variables with p≤0.05 in the final model were considered statistically associated with insulin resistance. RESULTS: Median age was 14 years (interquartile range: 13-16 years), and 25.3% of the sample showed insulin resistance. The variables associated with insulin resistance in the final model were age, body mass index-for-age (BMI/A), biochemical markers (triglycerides and high-density lipoprotein cholesterol) and saturated fat intake, with insulin resistance being more prevalent in individuals whose consumption of this type of fat was below the median of the sample distribution. CONCLUSIONS: Insulin resistance was prevalent in the adolescents analyzed and was significantly associated with metabolic variables and saturated fat intake.

Prevalence of Systemic Arterial Hypertension and Associated Factors Among Adults from the Semi-Arid Region of Pernambuco, Brazil.

BACKGROUND: Systemic arterial hypertension is a substantial public health problem responsible for millions of deaths per year worldwide. However, little is known about the epidemiology of this disease in areas distant from large urban centers in Brazil. Such information is necessary to plan health promotion strategies. OBJECTIVE: To estimate the prevalence of hypertension and determine its associated factors in adults residing in the semi-arid region of the state of Pernambuco, Northeastern Brazil. METHOD: This is a cross-sectional study conducted with a random sample of male and female adults. Individuals with systolic blood pressure ≥ 140 mm/Hg and/or diastolic blood pressure ≥ 90 mm/Hg and those who reported being under treatment with antihypertensive drugs were considered hypertensive. We collected data on demographic, socioeconomic, behavioral, and anthropometric characteristics, as well as health and nutrition. The statistical analysis used Pearson's chi-square test, the chi-square test for trend, and multivariate Poisson regression analysis. A p-value < 0.05 in the final model was considered indicative of statistical significance. RESULTS: The sample consisted of 416 individuals, and the prevalence of hypertension was 27.4% (95%CI 23.2 - 32.0). In the final model, the independent predictors of hypertension were age of 40 years or older (p = 0.000), low economic class (p = 0.007), smoking (p = 0.023), overweight determined by the body mass index (p = 0.003), and reduced glucose tolerance/diabetes mellitus (p = 0.012). CONCLUSION: The prevalence of hypertension was high and related to important risk factors. Thus, prevention and control strategies are recommended.

Consumption of in natura and ultra-processed foods in adults: an analysis of social, metabolic, and lifestyle determinants / Consumo de alimentos in natura e ultraprocessados em adultos: uma análise dos determinantes sociais, metabólicos e de estilo de vida

ABSTRACT Objective: To assess the social, metabolic, and lifestyle determinants of consumption of fruits, vegetables, and greens (FVG) and ultra-processed food (ULT) in adults from Pernambuco. Methods: Cross-sectional and analytical study, conducted in 2015/2016. In addition to sociodemographic variables, the determinants of lifestyle were level of physical activity, alcohol consumption, tobacco use, and metabolic variables were self-reported hypertension, blood glucose, and Body Mass Index (BMI). Consumption was measured by the Food Frequency Questionnaire, then created the Frequency of Consumption Index (SFI) of the mean intake of ULT and FVG foods. The indices of FVG and ULT consumption were transformed into quartiles and these variables were included in the multinomial logistic regression, considering their determinants when p<0.05. Results: The sample was representative of the state, with 1,067 people being interviewed, whose intake of ULT was higher than that of FVG in the lowest and highest quartile of the consumption index. Consumption of fruit and vegetables was higher in higher consumption of alcoholic beverages (p=0.031) and BMI>25 kg/m2 (p=0.047); and lower in the lowest income (p=0.001). ULT intake was higher in young adults (p=0.005), lower income (p=0.044), and controlled blood glucose (p=0.021). Rural areas were 52% less exposed to medium-high ULT consumption (p<0.006). Conclusion: Higher rate of ULT consumption in relation to fresh foods, with income as a common determinant, inversely associated with ULT intake and directly related to FVG, which demands structuring policies.

RESUMO Objetivo: Avaliar os determinantes sociais, metabólicos e de estilo de vida do consumo de frutas, legumes e verduras (FLV) e ultraprocessados (ULT) em adultos de Pernambuco. Métodos: Estudo transversal e analítico, realizado em 2015/2016. Além de variáveis sociodemográficas, os determinantes do estilo de vida foram nível de atividade física, doses de bebida alcoólica e uso de tabaco e os metabólicos foram hipertensão autorreferida, glicemia e Índice de Massa Corporal (IMC). O consumo foi mensurado por questionário de frequência alimentar, e, em seguida, criou-se Índice da Frequência de Consumo (IFC) da média de ingestão dos alimentos ULT e FVL. Os índices de consumo de FLV e ULT foram transformados em quartis e essas variáveis incluídas na regressão logística multinomial, considerando seus determinantes quando p<0,05. Resultados: A amostra foi representativa do estado, sendo entrevistadas 1.067 pessoas, cuja ingestão de ULT foi superior à de FVL no menor e no maior quartil do índice de consumo. O consumo de FLV foi superior no maior consumo de bebida alcoólica (p=0,031) e IMC>25 kg/m2 (p=0,047); e inferior na menor renda (p=0,001). O consumo de ULT foi maior em adultos jovens (p=0,005), menor renda (p=0,044) e glicemia controlada (p=0,021). A área rural estava 52% menos exposta ao consumo médio-alto de ULT (p<0,006). Conclusão: Maior índice de consumo de ULT em relação aos alimentos in natura, tendo a renda como um determinante comum, inversamente associada à ingestão de ULT e diretamente relacionada a FVL, o que demanda políticas estruturantes.

Anemia and associated factors in women at reproductive age in a Brazilian Northeastern municipality. / Anemia e fatores associados em mulheres de idade reprodutiva de um município do Nordeste brasileiro.

OBJECTIVE: To identify the prevalence of iron-deficiency anemia and associated factors in women at reproductive age in the city of Vitoria de Santo Antão, Pernambuco. METHODS: Cross-sectional study with a representative sample of 322 women aged between 15 and 49 years. Anemia was diagnosed by measuring hemoglobin below 12 g/dL. The independent variables were: demographic and socioeconomic conditions (age, race/color, education, literacy, presence of children aged < 5 years in the household, regime of residence occupation, ownership of assets, and per capita income), housing conditions (number of people in the household, number of bedrooms, and basic sanitation), food and nutrition security and women's health conditions (menarche, number of pregnancies, history of miscarriages, body mass index, and ferritin). Poisson regression was used to analyze the factors associated with anemia. RESULTS: The mean age of women surveyed was 31.1 ± 6.61 years old (standard deviation - SD) and the prevalence of anemia was 18.6% (95%CI 14.7 - 23.3). After multivariate analysis, anemia was significantly associated with age ≤ 19 years and low ferritin. CONCLUSION: The prevalence of anemia is characterized as a mild public health problem and follows the world trend in developing countries.

Situação de insegurança alimentar em domicílios de Pernambuco, Região Nordeste do Brasil: contribuições para discussão da violação do direito à alimentação / Food insecurity in households in Pernambuco, Northeast region of Brazil: contributions to the discussion on the violation of the right to adequate food

Resumo O objetivo deste estudo foi investigar os fatores associados à insegurança alimentar em domicílios do Estado de Pernambuco, localizado na região Nordeste do Brasil. Trata-se de um estudo transversal realizado em 1.008 domicílios particulares. Para a investigação, utilizou-se a Escala Brasileira de Insegurança Alimentar (EBIA) e foram analisadas associações com variáveis socioeconômicas, demográficas e práticas relacionadas à alimentação. Calculou-se razão de prevalência e ajuste por meio da regressão de Poisson, sendo estatisticamente significantes aquelas associações cujo p≤0,05. Encontrou-se prevalência de 68,4% de insegurança alimentar. Apresentaram associação com insegurança: escolaridade do chefe da família; renda per capita; participação no programa Bolsa Família; número de moradores; regime de ocupação do domicílio; classe social; práticas; e opiniões acerca da alimentação da família. O maior risco de insegurança foi encontrado naqueles com pior condição econômica, em beneficiários do Bolsa Família e naqueles que indicavam a falta de produtos ultraprocessados para melhorar a alimentação da família. Observou-se insegurança alimentar atrelada às condições de vulnerabilidade social e àqueles que não consideravam ter uma boa alimentação. Grande parte dos sujeitos referiram utilizar os recursos do Bolsa Família para aquisição de alimentos, o que reforça a importância dessa estratégia na promoção do acesso à alimentação.

Abstract This study aimed to investigate factors associated with food insecurity in households in the state of Pernambuco, in the Northeast region of Brazil. This is a cross-sectional study carried out in 1,008 private households. The investigation used the Brazilian Food Insecurity Scale (EBIA) and analyzed associations with socioeconomic and demographic variables, as well as practices related to eating. Prevalence ratio and adjustment were calculated using Poisson regression, and associations where p ≤ 0.05 were statistically significant. Food insecurity prevalence was 68.4%. Variables associated with insecurity were: education of the head of the family; per capita income; participation in the Bolsa Família Program; number of residents; occupation of the household; social class; practices and opinions about family eating habits. The greatest insecurity risk was found in those with the worst economic conditions, in beneficiaries of the Bolsa Família Program and in those who considered the lack of ultra-processed products to improve the family's diet. Food insecurity was linked to conditions of social vulnerability and to those who did not perceive that they had a good diet. Most of the subjects reported using resources of the Bolsa Família program to purchase food, which reinforces the importance of this strategy in promoting access to food.

ERICA: use of screens and consumption of meals and snacks by Brazilian adolescents.

OBJECTIVE To describe the length of exposure to screens and the prevalence of consumption of meals and snacks by Brazilian adolescents in front of screens. METHODS We evaluated 74,589 12 to 17-year old adolescents from 1,247 schools in 124 Brazilian municipalities. A self-administered questionnaire was used. Its segment regarding nutrition contained questions about using TV, computers, and video game systems, having meals while watching TV, and consuming snacks in front of screens. Consumption of meals and snacks in front of screens was analyzed according to the following variables: geographical region, gender, age range, type of school (public or private), and school shift. The prevalences and their respective 95% confidence intervals were estimated under a complex sampling design. RESULTS A great deal of the adolescents (51.8% IC95% 50.7-53.0) [corrected] reported spending two or more hours a day in front of screens. That habit was more frequent among male adolescents, private school students, morning shift students, and students from Brazil's South region. More than half of the adolescents (56.6%, 95%CI 55.4-57.8) reported almost always or always having meals in front of TV, and 39.6% (95%CI 38.8-40.5) of them said they consumed snacks in front of screens exactly as often. Both situations were the most prevalent ones among the girls, who attended public schools and were from Brazil's Midwest region. CONCLUSIONS Length of exposure to screens and consumption of meals and snacks almost always or always in front of screens are high among Brazilian adolescents. It is necessary to develop strategies aiming to reduce the length of screen use, considering the media reality that children and adolescents have been experiencing from earlier and earlier ages. That context must therefore be analyzed in an indissociable way.

[Identification of cutoff points for Homeostatic Model Assessment for Insulin Resistance index in adolescents: systematic review]. / Identificação dos pontos de corte do índice Homeostatic Model Assessment for Insulin Resistance em adolescentes: revisão sistemática.

OBJECTIVE: To identify cutoff points of the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) index established for adolescents and discuss their applicability for the diagnosis of insulin resistance in Brazilian adolescents. DATA SOURCE: A systematic review was performed in the PubMed, Lilacs and SciELO databases, using the following descriptors: "Adolescents", "insulin resistance" and "ROC curve". Original articles carried out with adolescents published between 2005 and 2015 in Portuguese, English or Spanish languages, which included the statistical analysis using ROC curve to determine the index cutoff (HOMA-IR) were included. DATA SYNTHESIS: A total of 184 articles were identified and after the study phases were applied, seven articles were selected for the review. All selected studies established their cutoffs using a ROC curve, with the lowest observed cutoff of 1.65 for girls and 1.95 for boys and the highest of 3.82 for girls and 5.22 for boys. Of the studies analyzed, one proposed external validity, recommending the use of the HOMA-IR cutoff >2.5 for both genders. CONCLUSIONS: The HOMA-IR index constitutes a reliable method for the detection of insulin resistance in adolescents, as long as it uses cutoffs that are more adequate for the reality of the study population, allowing early diagnosis of insulin resistance and enabling multidisciplinary interventions aiming at health promotion of this population.

[Short stature in children of Karapotó ethnic background, São Sebastião, Alagoas, Brazil]. / Déficit estatural em crianças do povo Karapotó, São Sebastião, Alagoas, Brasil.

OBJECTIVE: To describe the prevalence of short stature among children of Karapotó ethnic background. METHODS: Cross-sectional, population-based study that included children between 6 and 59 months of age from the Plak-Ô native village and the Terra Nova settlement, São Sebastião, Alagoas, carried out between 2008 and 2009. Short stature was evaluated by the Height/Age index, using as cutoff z score ≤-2. The prevalence of short stature was determined by comparing simple and relative frequencies. The population growth curves were compared to the WHO reference curves. Data analysis included the outcome variable: Height/Age and the predictor variables: place of residence, gender, age, anemia, birth weight, family income, maternal literacy. The chi-square test was used to compare the categorical variables, whereas the chi-square test with Yates correction was used for dichotomous variables, considering as statistically significant p-values≤0.05. RESULTS: The prevalence of short stature was 15.6% for children from the Terra Nova settlement and 9.1% for those from Plak-Ô native village. The prevalence of short stature among the Karapotó ethnicity was 13.4%. The variables: maternal literacy, family income and low birth weight were statistically associated with short stature. CONCLUSIONS: The observed short stature prevalence rates are significant, being characterized as a public health problem. Among the associated factors, the following are noteworthy: unfavorable conditions of maternal literacy, family income and low birth weight. The planning of strategies to reverse the situation must take such factors into consideration.

ERICA: intake of macro and micronutrients of Brazilian adolescents.

OBJECTIVE To describe food and macronutrient intake profile and estimate the prevalence of inadequate micronutrient intake of Brazilian adolescents. METHODS Data from 71,791 adolescents aged from 12 to 17 years were evaluated in the 2013-2014 Brazilian Study of Cardiovascular Risks in Adolescents (ERICA). Food intake was estimated using 24-hour dietary recall (24-HDR). A second 24-HDR was collected in a subsample of the adolescents to estimate within-person variability and calculate the usual individual intake. The prevalence of food/food group intake reported by the adolescents was also estimated. For sodium, the prevalence of inadequate intake was estimated based on the Tolerable Upper Intake Level (UL). The Estimated Average Requirement (EAR) method used as cutoff was applied to estimate the prevalence of inadequate nutrient intake. All the analyses were stratified according to sex, age group and Brazilian macro-regions. All statistical analyses accounted for the sample weight and the complex sampling design. RESULTS Rice, beans and other legume, juice and fruit drinks, breads and meat were the most consumed foods among the adolescents. The average energy intake ranged from 2,036 kcal (girls aged from 12 to 13 years) to 2,582 kcal (boy aged from14 to 17 years). Saturated fat and free sugar intake were above the maximum limit recommended (< 10.0%). Vitamins A and E, and calcium were the micronutrients with the highest prevalence of inadequate intake (> 50.0%). Sodium intake was above the UL for more than 80.0% of the adolescents. CONCLUSIONS The diets of Brazilian adolescents were characterized by the intake of traditional Brazilian food, such as rice and beans, as well as by high intake of sugar through sweetened beverages and processed foods. This food pattern was associated with an excessive intake of sodium, saturated fatty acids and free sugar.
