Exploring the Nexus between Food Systems and the Global Syndemic among Children under Five Years of Age through the Complex Systems Approach.

The intricate relationship between food systems and health outcomes, known as the food-nutrition-health nexus, intersects with environmental concerns. However, there's still a literature gap in evaluating food systems alongside the global syndemic using the complex systems theory, especially concerning vulnerable populations like children. This research aimed to design a system dynamics model to advance a theoretical understanding of the connections between food systems and the global syndemic, particularly focusing on their impacts on children under five years of age. The framework was developed through a literature review and authors' insights into the relationships between the food, health, and environmental components of the global syndemic among children. The conceptual model presented 17 factors, with 26 connections and 6 feedback loops, categorized into the following 5 groups: environmental, economic, school-related, family-related, and child-related. It delineated and elucidated mechanisms among the components of the global syndemic encompassing being overweight, suffering from undernutrition, and climate change. The findings unveiled potential interactions within food systems and health outcomes. Furthermore, the model integrated elements of the socio-ecological model by incorporating an external layer representing the environment and its natural resources. Consequently, the development of public policies and interventions should encompass environmental considerations to effectively tackle the complex challenges posed by the global syndemic.

Insufficient Answer During the Public Health Emergency: A Lesson from the Persistence of Food Insecurity in Low-Income Communities.

Cohort study in deprived communities to investigate the persistence of food insecurity (FI) during the COVID-19 was conducted. Sample were derived from a list of mobile phone numbers provided by community leaders and local nonprofit organizations. Temporal trends and prevalence ratios of FI persistence, categorized as "never," "occasional FI," "consistent FI," were calculated. A total of 302 households completed three assessments, the majority nonwhite women. During the follow-up, families covered by social assistance increased; however, their income decreased (p < 0.05). 33% were "consistent," and 46% "occasional" FI. Permanent difficulties accessing gas canisters, hygiene products, and hand sanitizers were observed.

Birth-to-childhood tracking of linear growth and weight gain in the MINA-Brazil Study.

OBJECTIVE: To investigate birth-to-childhood tracking of linear growth and weight gain across the distribution of length/height and weight for age z-scores and according to household wealth. METHODS: Data from 614 children from the MINA-Brazil Study with repeated anthropometric measurements at birth and up to age five years were used. Z-scores were calculated for length/height (HAZ) and weight (WAZ) according to international standards. Birth-to-childhood tracking was separately estimated using quantile regression models for HAZ and WAZ, extracting coefficients and 95% confidence intervals (95%CI) at the 25th, 50th, and 75th quantiles. In a subgroup analysis, we estimated tracking between birth and age two years, and between ages two and five years. To investigate disparities in tracking, interaction terms between household wealth indexes (at birth and age five years) and newborn size z-scores were included in the models. RESULTS: Tracking coefficients were significant and had similar magnitude across the distribution of anthropometric indices at age five years (HAZ, 50th quantile: 0.23, 95%CI: 0.11 to 0.35; WAZ, 50th quantile: 0.31, 95%CI: 0.19 to 0.43). Greater tracking was observed between ages two and five years, with coefficients above 0.82. Significantly higher tracking of linear growth was observed among children from wealthier households, both at birth, at the lower bounds of HAZ distribution (25th quantile: 0.30, 95%CI: 0.13 to 0.56), and during childhood, in the entire HAZ distribution at five years. For weight gain, stronger tracking was observed at the upper bounds of WAZ distribution at age five years among children from wealthier households at birth (75th quantile: 0.59, 95%CI: 0.35 to 0.83) and during childhood (75th quantile: 0.54, 95%CI: 0.15 to 0.93). CONCLUSION: There was significant tracking of HAZ and WAZ since birth, with indication of substantial stability of nutritional status between ages two and five years. Differential tracking according to household wealth should be considered for planning early interventions for preventing malnutrition.

Prevalence and predictors of breastfeeding in the MINA-Brazil cohort.

OBJECTIVE: To describe the prevalence and factors associated with exclusive (EBF) and continued breastfeeding (BF) practices among Amazonian children. METHODS: Data from 1,143 mother-child pairs recorded on the Maternal and Child Health and Nutrition in Acre (MINA-Brazil) birth cohort were used. Information on EBF and BF was collected after childbirth (July 2015-June 2016) and during the follow-up visits at 1 and 6 months postpartum, 1, 2, and 5 years of age. For longitudinal analysis, the outcomes were EBF and BF duration. Probability of breastfeeding practices were estimated by Kaplan-Meier survival analysis. Associations between baseline predictors variables and outcomes among children born at term were assessed by extended Cox regression models. RESULTS: EBF frequencies (95% confidence interval [95%CI]) at 3 and 6 months of age were 33% (95%CI: 30.2-36.0) and 10.8% (95%CI: 8.9-12.9), respectively. Adjusted hazard ratio for predictors of early EBF cessation were: being a first-time mother = 1.47 (95%CI: 1.19-1.80), feeding newborns with prelacteals = 1.70 (95%CI: 1.23-2.36), pacifier use in the first week of life = 1.79 (95%CI: 1.44-2.23) or diarrhea in the first two weeks of life = 1.70 (95%CI: 1.15-2.52). Continued BF frequency was 67.9% (95%CI: 64.9-70.8), 29.3% (95%CI: 26.4-32.4), and 1.7% (95%CI: 0.9-2.8) at 1, 2 and 5 years of age, respectively. Adjusted hazard ratio for predictors of early BF cessation were: male sex = 1.23 (95%CI: 1.01-1.49), pacifier use in the first week of life = 4.66 (95%CI: 2.99-7.26), and EBF less than 3 months = 2.76 (95%CI: 1.64-4.66). CONCLUSIONS: EBF and continued BF duration among Amazonian children is considerably shorter than recommendations from the World Health Organization. Significant predictors of breastfeeding practices should be considered for evaluating local strategies to achieve optimal breastfeeding practices.

Prevalence and correlates of childhood anemia in the MINA-Brazil birth cohort study.

OBJECTIVE: This study aimed to describe the prevalence and predictors of childhood anemia in an Amazonian population-based birth cohort study. METHODS: Prevalence of maternal anemia was estimated at delivery (hemoglobin [Hb] concentration < 110 g/L) in women participating in the MINA-Brazil birth cohort study and in their children, examined at ages one, two (Hb < 110 g/L), and five (Hb < 115 g/L). Moreover, ferritin, soluble transferrin receptor, and C-reactive protein concentrations were measured in mothers at delivery and in their 1- and 2-year-old children to estimate the prevalence of iron deficiency and its contribution to anemia, while adjusting for potential confounders by multiple Poisson regression analysis (adjusted relative risk [RRa]). RESULTS: The prevalence 95% confidence interval (CI) of maternal anemia, iron deficiency, and iron-deficiency anemia at delivery were 17.3% (14.0-21.0%), 42.6% (38.0-47.2%), and 8.7% (6.3-11.6)%, respectively (n = 462). At one year of age (n = 646), 42.2% (38.7-45.8%) of the study children were anemic, 38.4% (34.6-42.3%) were iron-deficient, and 26.3 (23.0-29.9) had iron-deficiency anemia. At two years of age (n = 761), these values decreased to 12.8% (10.6-15.2%), 18.1% (15.5-21.1%), and 4.1% (2.8-5.7%), respectively; at five years of age (n = 655), 5.2% (3.6-7.2%) were anemic. Iron deficiency (RRa = 2.19; 95%CI: 1.84-2.60) and consumption of ultra-processed foods (UPF) (RRa = 1.56; 95%CI: 1.14-2.13) were significant contributors to anemia at 1 year, after adjusting for maternal schooling. At 2 years, anemia was significantly associated with maternal anemia at delivery (RRa: 1.67; 95%CI: 1.17-2.39), malaria since birth (2.25; 1.30-3.87), and iron deficiency (2.15; 1.47-3.15), after adjusting for children's age and household wealth index. CONCLUSIONS: Anemia continues to be highly prevalent during pregnancy and early childhood in the Amazon. Public health policies should address iron deficiency, UPF intake, maternal anemia, and malaria to prevent and treat anemia in Amazonian children.

Adolescent pregnancy in Cruzeiro do Sul, Acre, Brazil: socioeconomic characteristics, prenatal and obstetric care. / Parturientes adolescentes em Cruzeiro do Sul, Acre, Brasil: características socioeconômicas e obstétricas.

The present study aimed to investigate the socioeconomic and obstetric characteristics of adolescent mothers and the complications they cause to maternal and neonatal health. This baseline data analysis of the MINA-Brazil birth cohort was conducted in the municipality of Cruzeiro do Sul, state of Acre, Brazil. The chi-square test was used to compare characteristics of adolescent and adult postpartum women, and multiple Poisson regression models with robust variance were used to assess associated factors. Among the postpartum women, 26.2% (95%CI: 24.0-28.4) were adolescents. Factors associated with childbirth in adolescence included: nine years or less of schooling (adjPR:1.36; 95%CI: 1.14-1.61), belongs to the lowest quartiles of the wealth index (1st quartile: adjPR:1.40; 95%CI: 1.08-1.80) (2nd quartile: adjPR:1.37; 95%CI: 1.08-1.74), primigravidae (adjPR:3.69; 95%CI: 2.98-4.57), low pre-pregnancy BMI (adjPR:1.28; CI95%: 1.04-1.57), urinary tract infection during pregnancy (adjPR:1.25; CI95%: 1.07-1.46) and less than six prenatal consultations (adjPR:1.42; 95%CI: 1.21-1.66). Poverty, little schooling, primigravidae, low pre-pregnancy BMI, urinary tract infection during pregnancy and few prenatal consultations were associated with childbirth during adolescence in a municipality in the Northern region of Brazil.

O objetivo do estudo foi investigar as características socioeconômicas e obstétricas de parturientes adolescentes e suas complicações sobre a saúde materna e neonatal. Trata-se de uma análise de dados da linha de base da coorte de nascimentos MINA-Brasil conduzida no município de Cruzeiro do Sul, estado do Acre. Utilizou-se teste qui-quadrado para comparar características das puérperas adolescentes com as adultas e modelos múltiplos de regressão de Poisson com variância robusta para avaliar fatores associados. Entre as puérperas estudadas, 26,2% (IC95%: 24,0-28,4) eram adolescentes. Os fatores associados ao parto na adolescência foram ter nove anos ou menos de estudo (RPaj:1,36; IC95%: 1,14-1,61), pertencer aos menores quartis do índice de riqueza (1° quartil: RPaj:1,40; IC95%: 1,08-1,80) (2° quartil: RPaj:1,37; IC95%: 1,08-1,74), ser primigesta (RPaj:3,69; IC95%: 2,98-4,57), baixo IMC pré-gestacional (RPaj:1,28; IC95%: 1,04-1,57), infecção urinária na gravidez (RPaj:1,25; IC95%: 1,07-1,46) e menos de seis consultas de pré-natal (RPaj:1,42; IC95%: 1,21-1,66). Pobreza, baixa escolaridade, primigestação, baixo IMC pré-gestacional, infecção urinária na gestação e menor número de consultas de pré-natal foram associados ao parto na adolescência em município da região Norte do Brasil.

Aleitamento materno exclusivo entre pessoas em situação de cárcere: abordagem interseccional e abolicionista para análise da produção científica no Brasil entre 2000 e 2022 / Exclusive breastfeeding among people in prison: an intersectional and abolitionist approach to analyzing scientific production in Brazil from 2000 to 2022

Resumo No Brasil, houve crescimento descontrolado do encarceramento feminino, sendo que não se interrompe essa situação em períodos de gravidez ou lactação. Foi realizada uma revisão de escopo com objetivo de mapear e sintetizar sistematicamente evidências, publicadas a partir do ano 2000, sobre a prática de aleitamento materno exclusivo (AME) entre pessoas em situação de cárcere no Brasil. A interseccionalidade e o abolicionismo penal foram as abordagens teórico-metodológicas utilizadas para análise dos artigos. Ao todo, 25 estudos foram selecionados, sendo 90% publicados entre 2010 e 2020. No âmbito de saúde materno-infantil, eles expuseram principalmente as dificuldades de manter o AME no cárcere, incluindo a indefinição de um período mínimo de estadia do bebê, a falta de orientação profissional à prática de AME e a estrutura inadequada das unidades prisionais. Na área do direito, os estudos relataram tensões entre a ordem disciplinar e o irredutível direito humano das crianças à alimentação. Os estudos focalizaram a investigação na vivência das mães, porém não questionaram as formas práticas e históricas do aprisionamento, em especial sobre corpos negros, femininos e pobres. Abordagens críticas e propositivas são necessárias à produção de evidências para a garantia de direitos à saúde e à alimentação.

Abstract In Brazil, there has been an uncontrolled increase in incarceration of women, and this situation is not interrupted during periods of pregnancy or lactation. A scoping review was carried out to systematically map and synthesize evidence published since 2000 on the practice of exclusive breastfeeding (EBF) among imprisoned people in Brazil. Intersectionality and penal abolitionism were the theoretical-methodological approaches used to analyze the studies. A total of 25 studies were selected, 90% of which were published from 2010 to 2020. In the context of maternal and child health, they mainly exposed the difficulties of maintaining EBF in prison, including the lack of definition of a minimum period of stay for the baby, the lack of professional guidance for the practice of EBF, and the inadequate structure of prison units. In the area of law, the studies reported tensions between the disciplinary order and children's irreducible human right to food. The studies focused the investigation on the mothers' experiences, but did not question the practical and historical forms of imprisonment, especially regarding Black, female, and poor bodies. Critical and propositional approaches are necessary to produce evidence toward the guarantee of rights to health and food.

Food and Nutrition Surveillance System markers predict diet quality.

OBJECTIVE: To investigate the performance of food consumption markers of the Food and Nutrition Surveillance System (Sisvan) in assessing the overall dietary quality. METHODS: The study was carried out based on the reproduction of responses to markers in 24-hour recall data from 46,164 individuals aged ≥ 10 years, from the 2017-2018 Household Budget Survey (POF). Seven Sisvan markers were evaluated, and two scores were calculated for each participant, based on the sum of the number of healthy food markers (beans, fruits, and vegetables, ranging from 0 to 3) and unhealthy (hamburgers/sausages, sweetened beverages, instant noodles/salt snacks/crackers, stuffed cookies/sweets/candies, ranging from 0 to 4) consumed. Linear regression analyses were used to assess the association between scores and diet quality indicators (ultra-processed foods, dietary diversity, and levels of saturated and trans fat, added sugar, sodium, potassium, and fiber in the diet). RESULTS: The score of healthy eating markers increased significantly with increasing dietary diversity and potassium and fiber contents in the diet, while the opposite trend was observed for the densities of added sugar, sodium, saturated and trans fat (p < 0.001). The score of unhealthy eating markers increased significantly with the increase in the consumption of ultra-processed foods and densities of added sugar, saturated and trans fat levels in the diet, while an inverse trend was observed for potassium and fiber (p < 0.001). The joint analysis of the combination of the two marker scores showed that individuals with better performance (3 in the healthy food score, and 0 in the unhealthy food score) have a lower number of inadequacies in nutrient consumption. CONCLUSION: Sisvan food consumption markers, quickly and easily applied and already incorporated into the Brazilian public health system, have good potential to reflect the overall dietary quality.

Improved estimates of foetal growth are associated with perinatal outcomes: A latent modelling approach in a population-based birth cohort.

Background: We aimed to estimate latent foetal growth conditions and explore their determinants among maternal characteristics and ultrasound biometric parameters. We additionally investigated the influence of foetal growth conditions on perinatal variables. Methods: We used data from live-born singletons in the Maternal and Child Health and Nutrition in Acre, Brazil (MINA-Brazil Study) population-based birth cohort. Maternal and perinatal characteristics were assessed in medical records from the maternity hospital and interviews with participants from July 2015 to June 2016. A sub-sample went through ultrasound examinations during the antenatal period, with assessment of foetal head and abdominal circumferences, and femur length. We estimated latent foetal growth conditions with a structural equation modelling framework, informed by the child's birth weight z-scores (BWZ) and birth length z-scores (BLZ) according to gestational age. Odds ratios and 95% confidence intervals (CIs) for the occurrence of perinatal events were estimated according to linear predictions of the latent variable. Results: We included 1253 participants. Latent foetal growth conditions explained 88.3% of BWZ and 53.7% of BLZ variation. Maternal elevated blood pressure, primiparity, smoking, malaria, and insufficient gestational weight gain negatively impacted foetal growth conditions. In the subsample (n = 499), ultrasound biometric parameters assessed at 28 weeks were positively associated with the latent variable, with the largest contribution from foetal abdominal circumference. Each standardised unit of predicted foetal growth conditions halved the chance for preterm birth (95% CI = 0.26, 0.74) and longer hospital stay (>3 days) (95% CI = 0.28, 0.88). Conversely, BWZ and BLZ were not independently associated with these perinatal variables in separate logistic regression models. Conclusions: Latent foetal growth conditions jointly encompassing weight gain and linear growth during gestation were negatively influenced by a scenario of dual burden of maternal morbidities, with perinatal implications.

Sisvan food intake markers: structure and measurement invariance in Brazil.

OBJECTIVE: To characterize the internal structure of the Food and Nutrition Surveillance System (Sisvan) form of food intake markers for individuals over 2 years of age and to investigate measurement invariance between Brazilian macro-regions, life stages and over the years. METHODS: A parallel analysis with factor estimation was carried out, complemented with exploratory factor analysis using all Sisvan records with valid responses in the country in 2015 (n = 298,253). Only the first record per individual was considered. Next, multigroup confirmatory factor analysis was used to investigate configural, metric and scalar invariance between the five macro-regions (Midwest, Northeast, North, Southeast, South) and life stages (children, adolescents, adults, elderly) in the same reference year. Invariance was evaluated longitudinally using valid individual records from 2015 to 2019 (n = 4,578,960). The adequacy of fit indices was observed at each step. RESULTS: Acceptable fit indices and adequate factor loadings were found for a two-dimensional model, which grouped ultra-processed foods (factor 1) and unprocessed or minimally processed foods (factor 2). The two-dimensional structure, with the respective items in each factor underlying the set of markers, was equivalent across macro-regions, life stages and longitudinally, confirming the configural invariance. The weights of each item and its scale were homogeneous for all groups of interest, confirming metric and scalar invariances. CONCLUSIONS: The internal structure of the Sisvan form of food intake markers adequately reflected its conceptual foundation, with stability of factors related to healthy and unhealthy eating in configuration, weights and scale in the investigated categories. These findings qualify food and nutritional surveillance actions, enhancing the use of Sisvan food intake markers in research, monitoring, individual guidance, and care production in the Brazilian Unified Health System.

Time trends and social inequalities in infant and young child feeding practices: national estimates from Brazil's Food and Nutrition Surveillance System, 2008-2019.

OBJECTIVE: To describe the time trends and socio-economic inequalities in infant and young child feeding practices in accordance with the Brazilian deprivation index (BDI). DESIGN: This time-series study analysed the prevalence of multiple breast-feeding and complementary feeding indicators based on data from the Brazilian Food and Nutrition Surveillance System, 2008-2019. Prais-Winsten regression models were used to analyse time trends. Annual percent change (APC) and 95 % CI were calculated. SETTING: Primary health care services, Brazil. PARTICIPANTS: Totally, 911 735 Brazilian children under 2 years old. RESULTS: Breast-feeding and complementary feeding practices differed between the extreme BDI quintiles. Overall, the results were more favourable in the municipalities with less deprivation (Q1). Improvements in some complementary feeding indicators were observed over time and evidenced such disparities: minimum dietary diversity (Q1: Δ 47·8-52·2 %, APC + 1·44, P = 0·006), minimum acceptable diet (Q1: Δ 34·5-40·5 %, APC + 5·17, P = 0·004) and consumption of meat and/or eggs (Q1: Δ 59·7-80·3 %, APC + 6·26, P < 0·001; and Q5: Δ 65·7-70·7 %, APC + 2·20, P = 0·041). Stable trends in exclusive breast-feeding and decreasing trends in the consumption of sweetened drinks and ultra-processed foods were also observed regardless the level of the deprivation. CONCLUSIONS: Improvements in some complementary food indicators were observed over time. However, the improvements were not equally distributed among the BDI quintiles, with children from the municipalities with less deprivation benefiting the most.

Exposure to ultra-processed foods during pregnancy and ultrasound fetal growth parameters.

Periconceptional maternal ultra-processed food (UPF) consumption impairs embryonic growth. Impacts of exposure to UPF on distinct components of fetal growth in late pregnancy are unknown. We investigated the influence of frequency of UPF consumption during pregnancy on fetal head circumference (HC), abdominal circumference (AC) and femur length (FL). This study included 417 live-born singleton pregnancies prospectively followed-up since the antenatal period in the MINA-Brazil Study, with an available ultrasound scan at >24 gestational weeks. Frequency of food groups consumption in the previous month was categorised as no/monthly, weekly or daily. Ultrasound scans were conducted at 27·8 (sd: 1·7) gestational weeks. HC, AC and FL z-scores were calculated for gestational age using the INTERGROWTH-21st Project standards. Simultaneous-quantile regression models were fitted at the 10th, 50th and 90th percentiles of the distribution of each ultrasound parameter according to UPF consumption, with adjustment for potential confounders. Participants were aged on average 24·7 (sd: 6·5) years, 44·8 % were primiparous, and 26·9 % and 24·9 %, respectively, had weekly and daily UPF consumption. Compared with no/monthly intake, daily UPF consumption impaired HC across its distribution, with significant effect sizes varying from -0·24 to -0·40 z-score. Weekly UPF consumption decreased HC at the 90th percentile by -0·39 z-score (95 % CI: -0·78, -0·01) and FL at the 50th percentile by -0·32 z-score (95 % CI: -0·60, -0·04). No association was noted with AC. Frequency of UPF consumption was negatively associated with skeletal components of fetal growth in late pregnancy. Infant body composition may benefit from healthy food practices since pregnancy.

Food intake markers in Sisvan: temporal trends in coverage and integration with e-SUS APS, Brazil 2015-2019. / Marcadores do consumo alimentar do Sisvan: tendência temporal da cobertura e integração com o e-SUS APS, 2015-2019.

The aim of the present study was to estimate the population coverage of recording food intake markers in Brazil's Food and Nutrition Surveillance System (Sisvan) and mean annual percent change (APC) in coverage according to the system used for data entry (e-SUS APS and Sisvan Web). We conducted an ecological time series study of the period 2015-2019. The data were stratified into region and age group. APC in coverage was calculated using Prais-Winsten regression and the correlation between APC and HDI, GDP per capita and primary healthcare coverage was assessed using Spearman's correlation coefficient. Population coverage of recording food intake markers at national level was 0.92% in 2019. Mean APC in coverage throughout the period was 45.63%. The region and age group with the highest coverage rate were the Northeast (4.08%; APC=45.76%, p<0.01) and children aged 2-4 years (3.03%; APC=34.62%, p<0.01), respectively. There was an upward trend in data entry using e-SUS APS, to the detriment of Sisvan Web. There was a positive correlation between APC in coverage using e-SUS APS and HDI and GDP per capita in some age groups. Population coverage of recording Sisvan food intake markers remains low across the country. The e-SUS APS has the potential to be an important strategy for expanding food and nutrition surveillance.

O objetivo deste estudo foi estimar a cobertura populacional e a taxa de incremento anual (TIA) média, em âmbito nacional, do registro de marcadores do consumo alimentar do Sistema de Vigilância Alimentar e Nutricional (Sisvan), entre 2015 e 2019, considerando a entrada dos dados via Estratégia e-SUS APS e Sisvan Web. Trata-se de estudo ecológico de séries temporais, com estratificação por macrorregiões e faixas etárias. A TIA da cobertura foi calculada utilizando regressão de Prais-Winsten e a correlação com IDH, PIB per capita e cobertura da APS foi avaliada por teste de Spearman. A cobertura populacional do registro de marcadores de consumo alimentar no país foi de 0,92% em 2019, com TIA significante de 45,63% desde 2015. As maiores coberturas foram observadas na região Nordeste (4,08%; TIA=45,76%, p<0,01) e em crianças entre 2 e 4 anos (3,03%; TIA=34,62%, p<0,01). Houve tendência crescente para a entrada dos dados via e-SUS APS, em detrimento do Sisvan Web. A TIA da cobertura dos registros via e-SUS APS exibiu correlação positiva com IDH e PIB per capita em alguns recortes etários. A cobertura populacional do registro de marcadores de consumo alimentar do Sisvan ainda se mostra incipiente no país e o e-SUS APS parece ser uma estratégia relevante para sua expansão.

Houve tendência crescente para a entrada dos dados via e-SUS APS, em detrimento do Sisvan Web. A TIA da cobertura dos registros via e-SUS APS exibiu correlação positiva com IDH e PIB per capita em alguns recortes etários. A cobertura populacional do registro de marcadores de consumo alimentar do Sisvan ainda se mostra incipiente no país e o e-SUS APS parece ser uma estratégia relevante para sua expansão.

Abstract The aim of the present study was to estimate the population coverage of recording food intake markers in Brazil's Food and Nutrition Surveillance System (Sisvan) and mean annual percent change (APC) in coverage according to the system used for data entry (e-SUS APS and Sisvan Web). We conducted an ecological time series study of the period 2015-2019. The data were stratified into region and age group. APC in coverage was calculated using Prais-Winsten regression and the correlation between APC and HDI, GDP per capita and primary healthcare coverage was assessed using Spearman's correlation coefficient. Population coverage of recording food intake markers at national level was 0.92% in 2019. Mean APC in coverage throughout the period was 45.63%. The region and age group with the highest coverage rate were the Northeast (4.08%; APC=45.76%, p<0.01) and children aged 2-4 years (3.03%; APC=34.62%, p<0.01), respectively. There was an upward trend in data entry using e-SUS APS, to the detriment of Sisvan Web. There was a positive correlation between APC in coverage using e-SUS APS and HDI and GDP per capita in some age groups. Population coverage of recording Sisvan food intake markers remains low across the country. The e-SUS APS has the potential to be an important strategy for expanding food and nutrition surveillance.

Quality of life and satisfaction of students with auriculotherapy in the covid-19 pandemic: a quasi-experimental study.

OBJECTIVES: to evaluate the quality of life before and after the application of auriculotherapy and the satisfaction of university students with the treatment during the covid-19 pandemic. METHODS: quasi-experimental study conducted with 44 students in a University Health Center. The intervention consisted of ten sessions of auriculotherapy focusing on emotional changes with quality of life assessment before and after treatment. The study also investigated the satisfaction concerning the intervention. RESULTS: predominated among the students: women, from health courses, in use of psychotropic drugs and complaining of emotional changes. There was a statistically significant increase in all domains of quality of life, and students were satisfied with the treatment. CONCLUSIONS: auriculotherapy improved the quality of life of university students during the covid-19 pandemic, and the level of satisfaction with the treatment was high.

Maternal pre-pregnancy body mass index, gestational weight gain and child weight during the first 2 years of life in an Amazonian birth cohort.

BACKGROUND: In socially vulnerable populations, evidence is needed regarding the role of maternal nutritional status on child weight during the first 2 years of life. OBJECTIVES: We aimed to assess the association of pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) with offspring BMI-for-age z-scores (BAZs) during the first 2 years of life. METHODS: A population-based birth cohort study was conducted with 900 mother-child pairs. Pre-pregnancy weight and weight at delivery were collected from medical records, and anthropometric data were measured at birth and at 6-month, 1-year and 2-year follow-up visits. Linear regression and linear mixed-effect models assessed associations with pre-pregnancy BMI, GWG and BAZ during the first 2 years of life. RESULTS: Pre-pregnancy overweight and obesity and excessive GWG were positively associated with BAZ at birth and at 1- and 2-year follow-up visits. There were no significant additional BAZ changes per year based on the exposures up to age 2 years. CONCLUSIONS: Elevated maternal pre-pregnancy BMI and GWG were associated with a child's higher BAZ at birth, and these differences remained constant throughout the first 2 years of life in Amazonian children. These findings highlight the importance of promoting adequate maternal weight before pregnancy and during prenatal care also in socially vulnerable populations.

Self-efficacy among health professionals to manage therapeutic groups of patients with obesity: Scale development and validity evidences.

Health professionals have to be confident to manage therapeutic groups of patients with obesity considering the potential of such approach to organize and provide health care. This study aimed to validate the scale of self-efficacy among health professionals to manage therapeutic groups of patients with obesity. Items were developed by an interprofessional group based on theoretical references on humanized healthcare. Scope, relevance, clarity, and comprehensibility of items and response options were evaluated by experts and health professionals. Using factor analysis and item response theory analysis, items with better discrimination were selected. The interpretation of the scores was proposed with a description of the self-efficacy around different levels. All steps were conducted using online forms. A pool of 21 items was proposed with up to five response options. Experts and health professionals retained 17 items with few changes in wording and four response options. The final scale was composed of 17 items, from which we derived three levels of self-efficacy (low, moderate, high). This study conceived a simple tool to assess health professionals' confidence in managing obesity in therapeutic groups, which may be helpful in designing and measuring the impact of interprofessional education programs to leverage health assistance quality.

Occurrence of depression and assessment of functional capacity in patients with vascular diseases admitted to a Vascular Surgery Service.

Background: Vascular diseases are associated with significant sequelae and clinical repercussions for the lives of affected patients, which are more serious among the elderly. The consequences of vascular disease, such as limb loss, chronic pain, prolonged hospitalization, and polypharmacy, reduce these patients' autonomy and independence, influencing their wellbeing and quality of life. Objectives: To determine the prevalence of depression and assess functional capacity in patients with vascular diseases admitted to a Vascular Surgery Service. Methods: This is a descriptive, cross-sectional study, carried out at the Vascular Surgery Service of a tertiary hospital with a non-random sample of patients selected consecutively. The geriatric depression scale short form (GDS-15) was used to assess depression and the Katz scale was used for functional assessment. Results: The prevalence of depression in these patients was 60.6%. Associations were observed between depression and consultation with a family doctor in the last 12 months, alcoholism, claudication, diabetes, and individuals who had had an amputation. Individuals' Katz index functional capacity scores were significantly associated with sociodemographic variables, conditions related to vascular disease, and hospitalization. Conclusions: There was a high prevalence of depression in patients with vascular diseases admitted to a vascular surgery service and important reductions in functional capacity in some groups, such as individuals with low educational levels, those who had chronic pain in the lower limbs, patients with diabetes, and those who had had an amputation.

Sisvan food intake markers: structure and measurement invariance in Brazil / Marcadores do consumo alimentar do Sisvan: estrutura e invariância de mensuração no Brasil

ABSTRACT OBJECTIVE To characterize the internal structure of the Food and Nutrition Surveillance System (Sisvan) form of food intake markers for individuals over 2 years of age and to investigate measurement invariance between Brazilian macro-regions, life stages and over the years. METHODS A parallel analysis with factor estimation was carried out, complemented with exploratory factor analysis using all Sisvan records with valid responses in the country in 2015 (n = 298,253). Only the first record per individual was considered. Next, multigroup confirmatory factor analysis was used to investigate configural, metric and scalar invariance between the five macro-regions (Midwest, Northeast, North, Southeast, South) and life stages (children, adolescents, adults, elderly) in the same reference year. Invariance was evaluated longitudinally using valid individual records from 2015 to 2019 (n = 4,578,960). The adequacy of fit indices was observed at each step. RESULTS Acceptable fit indices and adequate factor loadings were found for a two-dimensional model, which grouped ultra-processed foods (factor 1) and unprocessed or minimally processed foods (factor 2). The two-dimensional structure, with the respective items in each factor underlying the set of markers, was equivalent across macro-regions, life stages and longitudinally, confirming the configural invariance. The weights of each item and its scale were homogeneous for all groups of interest, confirming metric and scalar invariances. CONCLUSIONS The internal structure of the Sisvan form of food intake markers adequately reflected its conceptual foundation, with stability of factors related to healthy and unhealthy eating in configuration, weights and scale in the investigated categories. These findings qualify food and nutritional surveillance actions, enhancing the use of Sisvan food intake markers in research, monitoring, individual guidance, and care production in the Brazilian Unified Health System.

RESUMO OBJETIVO Caracterizar a estrutura interna do formulário de marcadores do consumo alimentar do Sistema de Vigilância Alimentar e Nutricional (Sisvan) para indivíduos maiores de 2 anos de idade e analisar evidências de invariância de mensuração entre macrorregiões brasileiras, fases do curso da vida e ao longo do tempo. MÉTODOS Realizou-se análise paralela com estimação de fatores complementada com análise fatorial exploratória a partir de todos os registros de primeiro acompanhamento do Sisvan com respostas válidas no país em 2015 (n = 298.253). A seguir, empregou-se a análise fatorial confirmatória multigrupo para investigação de evidências de invariância configural, métrica e escalar entre as cinco macrorregiões (Centro-Oeste, Nordeste, Norte, Sudeste e Sul) e fases do curso da vida (crianças, adolescentes, adultos e idosos), no mesmo ano de referência. Avaliou-se a invariância longitudinalmente a partir de registros individuais válidos de 2015 a 2019 (n = 4.578.960). A adequação de índices de ajuste foi observada a cada etapa. RESULTADOS Verificaram-se índices de ajuste aceitáveis e valores de carga fatorial adequados para um modelo bidimensional, que agrupou alimentos ultraprocessados (fator 1) e alimentos in natura ou minimamente processados (fator 2). A estrutura bidimensional, com os respectivos itens em cada fator subjacente ao conjunto de marcadores, foi equivalente entre macrorregiões, fases do curso da vida e longitudinalmente, confirmando a invariância configural. Os pesos de cada item e sua escala foram homogêneos para todos os grupos de interesse, confirmando as invariâncias métrica e escalar. CONCLUSÕES A estrutura interna do formulário de marcadores do consumo alimentar refletiu adequadamente seu embasamento conceitual, com estabilidade dos fatores relacionados à alimentação saudável e não saudável em configuração, cargas e escala nos recortes investigados. Esses achados qualificam ações de vigilância alimentar e nutricional, potencializando o uso dos marcadores do consumo alimentar do Sisvan em pesquisas, monitoramento, orientação individual e produção de cuidado no Sistema Único de Saúde.
