Weight Gain from Birth to Adolescence and TyG Index at Age 18 Years: A Cohort Study in Northeast Brazil.

BACKGROUND: Developmental models suggest that the phenotypes may arise from an immediate or mediated adaptive metabolic response of the perinatal growth. Evidence on the cumulative effects of growth and factors associated with risk of insulin resistance in adolescents is lacking. OBJECTIVE: To investigate the association between birthweight, weight gain during infancy, childhood and adolescence and the triglyceride-glucose index in adolescents. METHODS: This is a cohort of 217 children born at term, followed for the first six months, and reassessed at 8 and 18 years of age. The variables of interest were birthweight, postnatal growth defined as rapid postnatal growth when the weight gain from birth to six months of age was greater than 0.67 z-score, and the same criterion was used for high BMI gain from ages 6 months to 8 years, and from 8 to 18 years. Socioeconomic condition, nutritional status, practice of physical exercises and consumption of ultra-processed foods were verified. Multivariate linear regression analysis was used to verify the effect of the variables on the triglyceride-glucose index. RESULTS: Birthweight was not associated with triglyceride-glucose index in adolescence. Rapid postnatal growth during the first 6 months, higher BMI gain from 8 to 18 years and higher waist circumference contributed significantly to explain higher triglyceride-glucose index. CONCLUSION FOR PRACTICE: Our findings suggest that rapid postnatal growth may be one of the first signs of a higher triglyceride-glucose index in adolescence and that attention should be paid to the greater gain in body mass between childhood and adolescence for the risk of a higher triglyceride-glucose index.

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.

Adherence to 24-hour movement guidelines among rural Brazalian preschool children: associations with parenting practices.

BACKGROUND: Young children residing in rural areas of low-and-middle income countries (LMICs) such as Brazil are at greater risk of obesity and related chronic health conditions. Yet, the extent to which rural preschool children from Brazil aged 3- to 6-years meet the World Health Organisation (WHO) 24-hour movement guidelines is unknown. Parents play a central role in the development of children's movement behaviors with logistic support, co-participation, modelling, and setting rules and limits recognized as influential parenting practices. However, the bulk of parenting research has been conducted in families from high income countries (HICs) and little is known about the relationship between parenting practices and children's movement behaviors in LMIC communities. Therefore, the aims of this study were two-fold: (1) report the proportion of preschool children from low-income families in rural Brazil meeting the WHO 24-hour movement guidelines; and (2) determine associations with theory-based parenting practices related to physical activity, screen time, and sleep. METHODS: A representative sample of 324 families from a rural district in north-eastern Brazil completed a validated, culturally adapted interviewer-administered survey assessing child physical activity, screen time and sleep, and associated parenting practices. The proportion of children meeting the physical activity, screen time, and sleep recommendations and all combinations of these recommendations was calculated. Forward selection logistic regression was used to determine which parenting practices were associated with meeting the individual recommendations and the 24-hour movement guidelines. RESULTS: Less than half of the children (47.5%) met the physical activity recommendation, 22% met the screen time recommendation, 62% met the sleep recommendation, with just over 10% meeting all three recommendations in the 24-h movement guidelines. Having fewer rules and restrictions around indoor and outdoor play, limiting, or monitoring screen time, and maintaining a consistent bedtime routine were key parenting practices associated with children´s adherence to the 24-hour movement guidelines. CONCLUSION: Only 1 in 10 rural Brazilian preschool children meet the 24-hour movement guidelines. These findings underscore the need for family-based interventions targeting parenting practices to support healthful movement behaviors in young children from LMICs.

Psychometric properties of instruments to measure parenting practices and children's movement behaviors in low-income families from Brazil.

BACKGROUND: Childhood obesity has increased remarkably in low and middle-income (LMIC) countries. Movement behaviors (physical activity, screen time, and sleep) are crucial in the development of overweight and obesity in young children. Yet, few studies have investigated the relationship between children's movement behaviors and parenting practices because validated measures for use among families from LMIC are lacking. This study evaluated the psychometric properties of previously validated measures of young children's physical activity, screen time, and sleep and parenting practices, translated and culturally adapted to Brazilian families. METHODS: A total of 78 parent-child dyads completed an interviewer-administered survey twice within 7 days. Child physical activity, sedentary time and sleep were concurrently measured using a wrist-worn accelerometer. Internal consistency and test-retest reliability was assessed using McDonald's Omega and Intraclass Correlation Coefficients (ICC's). Concurrent validity was evaluated by calculating Spearman correlations between parent reported child behaviors and accelerometer measured behaviors. RESULTS: Seventeen of the 19 parenting practices scales exhibited acceptable internal consistency reliability (Ω ≥ 0.70). Test-retest reliability ICC's were acceptable and ranged from 0.82 - 0.99. Parent reported child physical activity was positively correlated with objectively measured total movement (rho= 0.29 - 0.46, p < .05) and energetic play (rho= 0.29 - 0.40, p < .05). Parent reported child screen time was positively correlated with objectively measured sedentary time; (rho = 0.26, p < .05), and inversely correlated with total movement (rho = - 0.39 - - 0.41, p < .05) and energetic play (rho = - 0.37 - - 0.41, p < .05). Parent reported night-time sleep duration was significantly correlated with accelerometer measured sleep duration on weekdays (rho = 0.29, p < .05), but not weekends. CONCLUSIONS: Measurement tools to assess children's movement behaviors and parenting practices, translated and culturally adapted for use in Brazilian families, exhibited acceptable evidence of concurrent validity, internal consistency, and test-retest reliability.

Toxic stress, health and nutrition among Brazilian children in shelters.

BACKGROUND: Living in a shelter is an adverse experience that generates toxic stress. This situation can cause the dysregulation of the hypothalamic-pituitary-adrenal axis and exert a negative impact on health.The aim of the present study was to determine the association between toxic stress and social, clinical and nutritional characteristics in children at welfare institutions in a city of northeastern of Brazil. METHODS: An analytical, cross-sectional study was conducted with male and female children up to 60 months of age who live in shelters. Hair cortisol was used for the assessment of stress (immunoassay). The anthropometric data collected were height for age, body mass index for age, arm circumference for age, and head circumference for age (expressed in z-scores). We also evaluated food intake using markers proposed by the Brazilian Dietary and Nutritional Vigilance Surveillance System as well as the occurrence of dental caries and anemia. RESULTS: Sixty-three children one to 60 months of age participated in the present study. Asthma was the most frequent disease (11.1%). The prevalence of short stature, anemia and dental caries in the sample was 22.2, 22.2 and 9.4%, respectively. Cortisol levels ranged from 0.93 pg/mg to 391.29 pg/mg (median: 6.17 pg/mg). Higher cortisol levels were found in children with illnesses (p = 0.012) and those who had been hospitalized after being admitted to the institutions (p = 0.001). CONCLUSIONS: The majority of children had unhealthy eating behavior. The cortisol concentrations found in the present study were suggestive of dysregulation of the hypothalamic-pituitary-adrenal axis. Hypercortisolism was associated with illness and hospitalization.

Vaccine uptake and associated factors in an irregular urban settlement in northeastern Brazil: a cross-sectional study.

BACKGROUND: Globally, childhood immunization saves the lives of 2-3 million children annually by protecting them against vaccine-preventable diseases. In 2017, 116.2 million children were vaccinated worldwide according to the World Health Organization. Nevertheless, figures suggest that 19.5 million children around the world fail to receive the benefits of complete immunization. METHODS: This cross-sectional study analyzed vaccine uptake and the factors associated with incomplete vaccination schedule in children of up to 36 months of age assisted by the family health strategy in an irregular settlement located in a state capital city in northeastern Brazil. This study was nested within a larger study entitled "Health, nutrition and healthcare services in an urban slum population in Recife, Pernambuco", conducted in 2015. A census included 309 children, with vaccination data obtained, exclusively, from their vaccination cards records. An ad hoc database was constructed with variables of interest. Absolute and relative values were calculated for the socioeconomic, demographic, obstetric and biological data. To identify possible factors associated with incomplete vaccination schedule, crude and multivariable Poisson regression analyses were performed, and conducted in accordance with the forward selection method with robust variance and the adjusted prevalence ratio was calculated with the 95% CI. Variables with p-values < 0.20 in the unadjusted stage were included in the multivariable analysis. The statistical significance of each variable was evaluated using the Wald test, with p-values < 0.05. RESULTS: Just half of the children (52,1%) was classified as complete vaccination schedule. In the final model, the factors associated with incomplete vaccination schedule were age 12-36 months and the mother who did not complete high school. CONCLUSION: The percentage of vaccine uptake found was far below the recommendation of the National Childhood Immunization Schedule and was associated with child's age and mother's education level. Based on these findings, the family healthcare teams may elaborate vaccination strategies aimed at reaching the coverage rates established by the national immunization program. Optimizing coverage will ultimately prevent the resurgence, at epidemic level, of infectious diseases that are already under control in this country.

Eating frequency and weight and body composition: a systematic review of observational studies.

OBJECTIVE: The present review aimed to examine the association of eating frequency with body weight or body composition in adults of both sexes. DESIGN: PubMed, EMBASE and Scopus databases were searched. PRISMA and MOOSE protocols were followed. Observational studies published up to August 2016 were included. The methodological quality of the studies was assessed with the Downs and Black checklist. SETTING: A systematic review of the literature. SUBJECTS: Adults (n 136 052); the majority of studies were developed in the USA and Europe. RESULTS: Thirty-one articles were included in the review: two prospective and twenty-nine cross-sectional studies. Thirteen per cent of the studies received quality scores above 80 %. The assessment of eating frequency and body composition or body weight varied widely across the studies. Potential confounders were included in 73 % of the studies. Fourteen studies reported an inverse association between eating frequency and body weight or body composition, and seven studies found a positive association. The majority of studies applied multiple analyses adjusted for potential confounders, such as sex, age, education, income, smoking, physical activity and alcohol intake. Six studies took into account under-reporting of eating frequency and/or energy intake in the analysis, and one investigated the mediation effect of energy intake. CONCLUSIONS: There is not sufficient evidence confirming the association between eating frequency and body weight or body composition when misreporting bias is taken into account. However, in men, a potential protective effect of high eating frequency was observed on BMI and visceral obesity.

The impact of home fortification with multiple micronutrient powder on vitamin A status in young children: A multicenter pragmatic controlled trial in Brazil.

Home fortification with multiple micronutrient powder (MNP) is effective in the prevention of anemia in young children. However, the impact on their vitamin A status remains controversial. This study aimed to evaluate the effect of MNP on vitamin A status in young Brazilian children. A multicenter pragmatic, controlled trial was carried out in primary health centers in four Brazilian cities. In the beginning of the study, the control group (CG) consisted of children 11-14 months old (n = 395) attending in routine pediatric health care. In parallel, the intervention group (IG) was composed of children 6-8 months old (n = 399), in the same health centers, who followed the intervention with MNP for 2-3 months. The analysis of the effect of MNP on vitamin A status was performed by comparing the IG with the CG after a 4- to 6-month follow-up when IG children had reached the age of the controls. The prevalence of vitamin A deficiency (VAD; serum retinol <0.70 µmol/L) in the CG was 16.2%, while in the IG was 7.5%-a 55% reduction in the VAD [prevalence ratio (95% confidence interval) = 0.45 (0.28; 0.72)]. This reduction was also significant when stratifying the study centers by coverage of the Brazilian Vitamin A Supplementation Program. The adjusted mean of vitamin A serum concentrations improved in the IG compared with CG children, with a shift to the right in the vitamin A distribution. Home fortification with MNP was effective in reducing VAD among young Brazilian children.

Temporal trend in fetal mortality according to two death avoidability classifications.

OBJECTIVE: To analyze the temporal trend of fetal mortality and its components, of avoidable and ill-defined causes according to two avoidability classifications in Recife, Pernambuco, 2010-2021. METHOD: Ecological study of temporal trends of fetal mortality in Recife, 2010-2021. The Brazilian List of Avoidable Causes of Death for fetal deaths (LBE-OF) and Brazilian List of Avoidable Causes of Death for children under five years of age (LBE < 5) were used. The Joinpoint regression model was applied to analyze the temporal trends. RESULTS: Trends in fetal mortality and its components were stationary. The group of avoidable causes presented higher mortality rates in both classifications, with an increasing trend according to the LBE-OF (Annual Percentage Change-APC: 2,1; p = 0,018) and stationary according to the LBE < 5. There was a decreasing trend in mortality from ill-defined causes only according to the LBE-OF (APC: -12,3; p < 0,001). CONCLUSION: The results showed the stagnation of the temporal trend in fetal mortality, the avoidability of most deaths, and the potential of LBE-OF in monitoring the quality of information on the basic causes and avoidability of fetal deaths.

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.

Cut-off points of adiposity indices associated with insulin resistance in Brazilian postpubertal adolescents.

OBJECTIVES: This study aims to establish cut-off points for lipid accumulation product and tri-ponderal mass index to identify insulin resistance (IR) in Brazilian postpubertal adolescents. METHODS: We conducted an analysis of postpubertal adolescents enrolled in the national school-based cross-sectional study of cardiovascular risks in adolescents (ERICA-BRAZIL) from February 2013 to November 2014. IR was defined by homeostatic model assessment index for IR values ≥2.32 for girls and ≥2.87 for boys. The analysis involved calculating the area under receiver operating characteristic curves, sensitivity values, specificity, positive and negative predictive values, and positive and negative likelihood ratios to determine reference values of indices with optimal performance. RESULTS: The sample was comprised of 14 026 adolescents, with 25.3% (95% confidence intervals: 24.6%-26.1%) exhibiting IR, more prevalent among girls and overweight individuals. The ideal lipid accumulation product cut-off points associated with IR were 13.5 for the total population, 13.8 for male adolescents, and 13.5 for girls. Regarding tri-ponderal mass index, the optimal cut-off values for identifying IR were 14.1, 13.9, and 14.5 kg/m³ in the general sample, boys, and girls, respectively. CONCLUSIONS: This study establishes cut-off points for adiposity indices, demonstrating their effectiveness in screening for IR in postpubertal Brazilian adolescents.

[Evaluation of the effectiveness of the intervention to improve the Brazilian Mortality Information System in Pernambuco, Brazil: a quasi-experimental study]. / Avaliação da efetividade da intervenção para aprimoramento do Sistema de Informações sobre Mortalidade em Pernambuco, Brasil: um estudo quase-experimental.

This study evaluated the influence of the variation in the implementation of the Brazilian Mortality Information System (SIM) on the results, before and after the intervention to improve the system in Pernambuco, Brazil. The SIM logical model and matrix of indicators and assessment were described, primary data were collected from the 184 municipalities and secondary data were collected from the system database. The degree of implementation (DI) was obtained from the indicators of structure and process, and then related to result indicators, based on the model. The intervention was directed at the shortcomings identified, and developed using strategic stages. The percentage of annual variation of the DI and the results before and after the intervention were calculated. The SIM was classified as partially implemented in the pre- (70.6%) and post-intervention (73.1%) evaluations, with increments in all components. The Health Regions followed the same classification of the state level, except for XII (80.3%), regarding implemented score after the intervention. The coverage of the system; deaths with a defined underlying cause; monthly transfer; and timely submission of data were above 90% in both evaluations. There was an improvement in the completeness of infant Death Certificates and in the timely recording of notifiable events. Strengthening the management and operationalization of the SIM with interventions applied to data registration can improve the system's results.

Parental Influences on Physical Activity and Screen Time among Preschool Children from Low-Income Families in Brazil.

Background: Children from low-middle income countries (LMIC) are disproportionately affected by obesity, and low physical activity (PA) and high screen time (ST) are major contributors. Parents are key influencers on children's PA and ST, yet, no study has investigated relationships between parenting practices and children's PA and ST in LMIC families. This study examined parental influences on PA and ST among preschool-aged children from low-income families in Brazil. Methods: Parents completed a validated, culturally adapted interviewer-administered survey assessing child ST and parenting practices. Child sedentary time, total movement, and energetic play were measured by accelerometery. Results: Data were available on 77 parent-child dyads [mean age 4.6 years (standard deviation = 0.8), 53% male, and 41% mixed-race]. Parenting practices associated with greater PA were use of PA to reward/control behavior (rho = 0.34-0.49), limiting or monitoring ST (rho = 0.30), explicit modeling/enjoyment of PA (rho = 0.24), verbal encouragement for PA (rho = 0.30), and importance and value of PA (rho = 0.24-0.38; p < 0.05). Parenting practices associated with higher ST were rules around active play indoor (rho = 0.23), use of ST to reward/control behavior (rho = 0.30), exposure to screens (rho = 0.40), and explicit modeling/enjoyment of ST (rho = 0.50; p < 0.05). Conclusion: Recognized parenting practices such as explicit modeling of PA and ST, monitoring and limiting ST, and rules and restrictions about PA and ST are associated with young children's PA and ST in low-income Brazilian families. The findings identify potential targets for family-based interventions to promote healthy lifestyle behaviors and prevent childhood obesity.

[From production to impacts on health and the environment: an analysis of food systems in Brazil, Colombia and Panama]. / Da produção aos impactos na saúde e no ambiente: uma análise dos sistemas alimentares de Brasil, Colômbia e Panamá.

The scope of this article is to describe the main components of the food systems of Brazil, Colombia and Panama. It involved a narrative review of the literature from 2000 to 2022, based on the concept of food systems proposed by the Committee on World Food Security. A system of agro-industrial production, monoculture, use of pesticides and exploitation of natural resources predominates in all three countries, and the area occupied by family farmers is reduced. Multinational supermarket chains dominate food distribution, essentially in large urban centers, despite the increasing search for alternative models. Advances have been made in food labeling regulation (Colombia and Brazil) and in the taxation of sugar-sweetened beverages (Panama). The predominant food systems in these countries generate a significant and negative environmental impact, favor the consumption of ultra-processed foods, high prevalence of obesity and chronic non-transmissible diseases and increase in hunger, violating the human right to adequate food.

O objetivo deste artigo é descrever os principais componentes dos sistemas alimentares de Brasil, Colômbia e Panamá. Revisão narrativa de literatura dos anos 2000 a 2022, ancorada no conceito de sistemas alimentares do Comitê de Segurança Alimentar Mundial. Nos três países, predomina um sistema de produção agroindustrial, monocultura, uso de agrotóxicos e exploração dos recursos naturais. A área ocupada por produtores familiares é reduzida. As redes multinacionais de supermercados dominam a distribuição dos alimentos, essencialmente nos grandes centros urbanos, apesar da crescente busca por modelos alternativos. Nota-se avanços na regulamentação da rotulagem de alimentos (Colômbia e Brasil) e na tributação de bebidas açucaradas (Panamá). Os sistemas alimentares predominantes nesses países geram importante e negativo impacto ambiental, favorecem o consumo de alimentos ultraprocessados, a elevada prevalência de obesidade e doenças crônicas não transmissíveis e o aumento da fome, violando o direito humano à alimentação adequada.

Temporal evolution of anemia in children aged six to 59 months in the state of Pernambuco, Brazil, 1997 to 2016. / Evolução temporal da anemia em crianças de seis a 59 meses no estado de Pernambuco, Brasil, 1997 a 2016.

OBJECTIVE: To analyze the temporal evolution of anemia in children aged six to 59 months in Pernambuco, based on population surveys from 1997, 2006, and 2016 and the factors associated with the situation in 2016. METHODS: The field studies took place in the participants' households, in the Recife Metropolitan Area, as well as in the urban and rural inland. The trend study of anemia in children used data from the State Health and Nutrition Survey (Pesquisa Estadual de Saúde e Nutrição - PESN) II (40.9%) and III (32.8%). Data from PESN IV were collected using questionnaires administered to families to verify socioeconomic and individual conditions, as well as anthropometric - weight and height - and biochemical - hemoglobin - records. We adopted the test for trend in proportion for the time trend study and Poisson regression for hypothesis tests for the associated factors. Statistically significance was set at a p-value<0.05. RESULTS: In 2016, the prevalence of anemia was 24.2%, indicating a significant reduction in disease incidence. In children aged 6-23 months, this number decreased from PENS II and III to PENS IV - 63 and 55.6 to 37.7% (p<0.001), respectively. In 2016, the statistically significant variables for anemia in children were maternal hemoglobin, child's age, current or recent case of diarrhea, and weight-for-age index. CONCLUSION: Between 1997 and 2016, anemia rates decreased, showing an epidemiological trend that can contribute to continuously improve the health of children under five years of age in Pernambuco.

OBJETIVO: Analisar a evolução temporal da anemia em crianças de seis a 59 meses em Pernambuco, com base nos inquéritos populacionais de 1997, 2006 e 2016 e os fatores associados à situação em 2016. MÉTODOS: Os estudos de campo ocorreram nos domicílios dos participantes, na Região Metropolitana do Recife, interior urbano e rural. No estudo de tendência da anemia em crianças, utilizaram-se dados da II (40,9%) e III PESNs (Pesquisa Estadual de Saúde e Nutrição) (32,8%). Os dados da IV PESN foram coletados por formulários com famílias para verificação das condições socioeconomicas e individuais, bem como registros antropométricos, peso e altura, e bioquímicos, hemoblobina. Para o estudo de tendência temporal, utilizou-se o teste de tendência de proporção; e para os fatores associados a regressão de Poisson para testes de hipóteses. Estatisticamente considerou-se significante o valor p<0,05. RESULTADOS: A prevalência de anemia, em 2016, foi de 24,2%, expressando uma diminuição significativa na ocorrência da doença. Nas crianças de 6­23 m., houve redução da II e III para IV PESN de 63 e 55,6 para 37,7% (p<0,001), respectivamente. Em 2016, as variáveis com significância estatística para a anemia em crianças foram a hemoglobina materna, a idade da criança, a ocorrência atual ou recente de diarreia e o índice P/I. CONCLUSÃO: Entre 1997 e 2016, houve redução da anemia, demostrando uma tendência epidemiológica que pode contribuir para melhoria contínua da saúde das crianças abaixo de cinco anos em Pernambuco.

Birthweight, postnatal growth and blood pressure in adolescents of low socioeconomic condition: a cohort study in Northeast Brazil.

OBJECTIVE: To verify the influence of low birth weight and rapid postnatal weight gain and associated factors on blood pressure in adolescence in a population of low socioeconomic status, considering that injuries occur in the perinatal period can be predictors of future metabolic changes and are still poorly explored. METHODS: A cohort study was carried out with 208 adolescents, 78 born with low weight and 130 born with appropriate weight. The infants were followed up during the first six postnatal months and reassessed at 8 and 18 years of age. The independent variables were birthweight and postnatal weight gain. Rapid postnatal weight gain was defined when above 0.67 z score. The co-variables were sex, maternal height and family income at birth, nutritional status at eight years old, socioeconomic conditions, nutritional status, fat mass index, and physical activity level at 18 years. The outcome variable was blood pressure at 18 years old. The bivariate and multivariable logistic regression analysis were realized and p < 0,05 was considered significant. RESULTS: The proportion of adolescents with elevated blood pressure was 37.5%. The multivariable logistic regression analysis showed the variables independently associated with a higher chance of elevated blood pressure in adolescence were rapid postnatal weight gain (OR = 2.74; 95% CI 1.22-6.14; p = 0.014), male sex (OR = 4.15; 95% CI 1.66-10.38; p = 0.002) and being physically active (OR = 2.70; 95% CI 1.08-6.74; p = 0.034). CONCLUSIONS: The rapid postnatal weight gain was a predictor for elevated blood pressure in adolescence, independently of other factors.

Factors associated with anemia and vitamin A deficiency in Brazilian children under 5 years old: Brazilian National Survey on Child Nutrition (ENANI-2019).

Factors associated with anemia and vitamin A deficiency were investigated in 7,716 children 6-59 months of age studied in the Brazilian National Survey on Child Nutrition (ENANI-2019). We adopted a hierarchical approach based on a United Nations Children's Fund (UNICEF) theoretical model with three levels, stratifying by age (6-23; 24-59 months). Prevalence ratio (PR) and 95% confidence interval (95%CI) were estimated. Enabling determinants: a higher prevalence of anemia was observed in children 6-23 months whose mothers had ≤ 7 years of schooling (PR = 1.92; 95%CI: 1.10; 3.34), < 20 years old (PR = 2.47; 95%CI: 1.34; 4.56) or 20-30 years old (PR = 1.95; 95%CI: 1.11; 3.44), mixed-race (PR = 1.57; 95%CI: 1.06; 2.23); and in children 24-59 months in the North Region (PR = 3.11; 95%CI: 1.58; 6.13). A higher prevalence for vitamin A deficiency was observed in children 6-23 months from Central-West (PR = 2.32; 95%CI: 1.33; 4.05), and in children 24-59 months living in the North (PR = 1.96; 95%CI: 1.16; 3.30), South (PR = 3.07; 95%CI: 1.89; 5.01), and Central-West (PR = 1.91; 95%CI: 1.12; 3.25) and whose mothers were 20-34 years (PR = 1.62; 95%CI: 1.11; 2.35). Underlying determinants: the presence of more than one child < 5 years old in the household was associated with a higher prevalence of anemia (PR = 1.61; 95%CI: 1.15; 2.25) and vitamin A deficiency (PR = 1.82; 95%CI: 1.09; 3.05) in children 6-23 months. Immediate determinants: consumption of 1-2 groups of ultra-processed foods in children 24-59 months (PR = 0.44; 95%CI: 0.25; 0.81) and lack of breastfeeding in the day before in children 6-23 months (PR = 0.56; 95%CI: 0.36; 0.95) were associated with lower prevalence of anemia and vitamin A deficiency. Public policies focused on geographically and socially vulnerable groups are needed to promote equity.

It will be presented the main academic contributions of Professor Ana Marlúcia Oliveira (AMO) (in memoriam), nutritionist, professor at the School of Nutrition at the Federal University of Bahia, Ph.D. in epidemiology and CNPQ Researcher level A, from 1980 to 2021. Professor Ana accumulated, throughout her academic career, scientific articles published in national and international journals; book and book chapters authored by her; papers presented at scientific events, in addition to guiding scientific projects, dissertations and theses. She has coordinated several research projects in the field of food and nutrition in public health, with a focus on nutritional epidemiology. The scope of the subjects addressed in her scientific production expressed the concern that mobilized her around the production of knowledge to face the complex health and nutrition problems in Brazil. Her way of being in the world, welcoming and caring for people who approached her seeking qualification opportunities, her example, words and teachings influenced, and still influence, the trajectory and training of nutritionists, professors and researchers at ENUFBA and other national and international institutions. She was a Brazilian researcher and intellectual committed to the health of the most vulnerable populations and the fight against malnutrition and hunger in our country. Her wide and fruitful work left us a legacy to be remembered and continued. Some of her friends, colleagues and collaborators pay this tribute to her memory, to her example and to the legacy she left for all of us and future generations.

Temporal trends and anaemia-associated factors in 6- to 59-month-old children in Northeast Brazil.

OBJECTIVE: To analyse the trends and factors associated with anaemia in 6- to 59-month-old children in Northeast Brazil. DESIGN: Cross-sectional study assessed information from the second and third Pernambuco State Health and Nutrition Surveys carried out in 1997 and 2006. A multiple regression analysis was performed from a conceptual model addressing biological and socio-economic factors, housing and sanitation conditions, maternal factors, health care and nutrition, consumption, morbidity and nutritional status. Poisson's regression with robust variance was used. SETTING: Pernambuco, Brazil. SUBJECTS: A total of 777 and 993 children, respectively, in the second and third Pernambuco State Health and Nutrition Surveys. RESULTS: The prevalence of anaemia (Hb < 11 g/dl) decreased by 19·3 % (40·9 % down to 33·0 %) between surveys. Maternal education level (less than 8 years in school), households ranked in the lowest environmental index tertile and children between 6 and 23 months of age were the variables common to the final models in the surveys of 1997 and 2006. Elements like living in rural areas, household income less than two minimum official wages and low birth weight were still present in the final model of the 1997 survey. Households ranked in the lowest economic index tertile were associated with anaemia in the model of the 2006 survey. CONCLUSIONS: The study results are quite encouraging from the perspective of reducing the prevalence of anaemia. Maternal education level, environmental conditions and child age were determinant factors in both surveys, and economic factors were determinant in 2006.

Cardiovascular risk behavior among industrial workers in the Northeast of Brazil: a cluster analysis.

This research aimed to investigate the occurrence of clusters of cardiovascular risk behaviors and their association with social demographic and occupational characteristics in a population of industrial workers in the metropolitan area of Recife, Brazil. It was a transversal study with 727 workers of both genders. We identified cluster distribution from the variables: smoking, alcohol consumption, physical activity and waist circumference, by a combination of hierarchical and non-hierarchical analysis. We later tested the association with the social demographic and occupational variables with a multi-varied analysis. We have identified a protection cluster (sufficient physical activity, moderate alcohol consumption) and a risk cluster (high waist circumference, sedentarism, smoking, excessive alcohol consumption). The protection cluster was positively associated with night shift or variable shift work (RP: 1.66, IC95%: 1.26-2.17), and the risk cluster was associated with women (RP: 1.15, IC95%: 1.01-1.31). Cluster analysis allowed to identify that, for day shift workers and women, the shortest daytime outside the work environment can influence the adoption of cardiovascular risk behaviors.
