Integrity at stake: confronting "publish or perish" in the developing world and emerging economies.

The scientific community faces significant ethical challenges due to the "publish or perish" culture, particularly in developing and emerging economies. This paper explores the widespread unethical practices in scientific publishing, including the sale of authorships, the proliferation of "paper mills," and the misuse of artificial intelligence to produce fraudulent research. These practices undermine the integrity of scientific research, skew publication metrics, and distort academic rankings. This study examines various instances of academic fraud, emphasizing the impact on low-income countries, with specific cases from Latin America. Recommendations include stricter verification of authorship, disciplinary measures for scientific fraud, and policies promoting transparency and accountability in research. Addressing these challenges is crucial for maintaining the integrity and credibility of scientific endeavors globally.

Do behavioral drivers matter for healthcare decision-making during crises? A study of low-income women in El Salvador during the COVID-19 pandemic.

Understanding health-seeking behaviors and their drivers is key for governments to manage health policies. A growing body of research explores the role of cognitive biases and heuristics in health and care-seeking behaviors, but little is known about how a context of heightened anxiety and uncertainty might influence these behavioral drivers. This study analyzes the association between four behavioral predictors-internal locus of control, impatience, optimism bias, and aspirations-and healthcare decisions among low-income women in El Salvador, controlling for other factors. We find positive associations between internal locus of control and preventive health behaviors during the COVID-19 pandemic. For instance, a one standard deviation increase in locus of control is associated with a 10% increase in an index measuring the use of masks, distancing, hand washing, and vaccination. Locus of control was also associated with women's use of preventive health services (one standard deviation improves the likelihood of having a hypertension test in the last six months by 5.8 percentage points). In a sub-sample of mothers, we find significant relationships between the four behavioral drivers and the decisions the mothers make for their children. However, we find these associations are less robust compared to the decisions they make for themselves. Some associations were stronger during the pandemic, suggesting that feelings of uncertainty and stress could amplify behavioral drivers' influence on health-related behaviors. This novel finding is relevant for designing policy responses for future shocks. JEL CODES: I12, D10, D91, I30.

Development of Automated Triggers in Ambulatory Settings in Brazil: Protocol for a Machine Learning-Based Design Thinking Study.

BACKGROUND: The use of technologies has had a significant impact on patient safety and the quality of care and has increased globally. In the literature, it has been reported that people die annually due to adverse events (AEs), and various methods exist for investigating and measuring AEs. However, some methods have a limited scope, data extraction, and the need for data standardization. In Brazil, there are few studies on the application of trigger tools, and this study is the first to create automated triggers in ambulatory care. OBJECTIVE: This study aims to develop a machine learning (ML)-based automated trigger for outpatient health care settings in Brazil. METHODS: A mixed methods research will be conducted within a design thinking framework and the principles will be applied in creating the automated triggers, following the stages of (1) empathize and define the problem, involving observations and inquiries to comprehend both the user and the challenge at hand; (2) ideation, where various solutions to the problem are generated; (3) prototyping, involving the construction of a minimal representation of the best solutions; (4) testing, where user feedback is obtained to refine the solution; and (5) implementation, where the refined solution is tested, changes are assessed, and scaling is considered. Furthermore, ML methods will be adopted to develop automated triggers, tailored to the local context in collaboration with an expert in the field. RESULTS: This protocol describes a research study in its preliminary stages, prior to any data gathering and analysis. The study was approved by the members of the organizations within the institution in January 2024 and by the ethics board of the University of São Paulo and the institution where the study will take place. in May 2024. As of June 2024, stage 1 commenced with data gathering for qualitative research. A separate paper focused on explaining the method of ML will be considered after the outcomes of stages 1 and 2 in this study. CONCLUSIONS: After the development of automated triggers in the outpatient setting, it will be possible to prevent and identify potential risks of AEs more promptly, providing valuable information. This technological innovation not only promotes advances in clinical practice but also contributes to the dissemination of techniques and knowledge related to patient safety. Additionally, health care professionals can adopt evidence-based preventive measures, reducing costs associated with AEs and hospital readmissions, enhancing productivity in outpatient care, and contributing to the safety, quality, and effectiveness of care provided. Additionally, in the future, if the outcome is successful, there is the potential to apply it in all units, as planned by the institutional organization.

Improvements in habitability and housing satisfaction after dwelling regeneration in social housing complexes. The RUCAS study.

Housing is a pressing problem worldwide and a key determinant of health and wellbeing. The right to adequate housing, as a pillar of the right to an adequate standard of living, means more than a roof to live under. Adequate means the dwelling must fulfill material functions and psychosocial functions, thus contributing to dwellers health and wellbeing. Social housing policies aim to fulfill the right to housing, but frequently fail in fulfilling the right to it being adequate. This study capitalizes on the implementation of a national urban regeneration program in two social housing villas in central Chile (one in Santiago, in the central valley, the other in Viña del Mar, a coastal city) to run a natural experiment assessing the impact of dwelling renovation on several dimensions of perceived habitability and housing satisfaction among the -mostly female-household homemakers. We use 5 waves of survey data collected with a step-wedge design to estimate the association between a time-varying exposure status (the intervention) and 7 binary outcomes for habitability and 5 for housing dissatisfaction, including overall housing satisfaction. We use Poisson regression models with robust variance and a random intercept at the respondent level. At baseline, reports of poor habitability and dissatisfaction across all features were markedly high, the highest levels of dissatisfaction being with acoustic insulation and dwelling size in both villas, and with indoor temperature in Santiago. The intervention resulted in statistically significant and markedly large improvements in reported habitability and dissatisfaction relative to those housing components targeted by the intervention, as well as with overall dwelling satisfaction in both study cases. Implications are, first, that the policy response to quantitative housing deficits must not overlook housing quality; second, that housing renovation appears as a promising intervention for qualitative housing crises; third, that while improvements in habitability and satisfaction are specific to the interventions in place, overall housing satisfaction can improve in more limited, tailored, dwelling renovation interventions. Social housing renovation in Latin America appears as a promising intervention to improve quality of life among the urban poor dwellers and reduce inequalities in health related to housing conditions.

An update on the mechanisms and risk factors for anesthesia-related cardiac arrest in children: a narrative review.

The relation between surgery and anesthesia safety in children and a country's Human Development Index (HDI) value has been described previously. The aim of this narrative review was to provide an update on the mechanisms and risk factors of Anesthesia-Related Cardiac Arrest (ARCA) in pediatric surgical patients in countries with different HDI values and over time (pre-2001 vs. 2001‒2024). Electronic databases were searched up to March 2024 for studies reporting ARCA events in children. HDI values range from 0 to 1 (very-high-HDI countries: ≥ 0.800, high-HDI countries: 0.700‒0.799, medium-HDI countries: 0.550‒0.699, and low-HDI countries: < 0.550). Independent of time, the proportion of children who suffered perioperative Cardiac Arrest (CA) attributed to anesthesia-related causes was higher in very-high-HDI countries (50%) than in countries with HDI values less than 0.8 (15‒36%), but ARCA rates were higher in countries with HDI values less than 0.8 than in very-high-HDI countries. Regardless of the HDI value, medication-related factors were the most common mechanism causing ARCA before 2001, while cardiovascular-related factors, mainly hypovolemia, and respiratory-related factors, including difficulty maintaining patent airways and adequate ventilation, were the major mechanisms in the present century. Independent of HDI value and time, a higher number of ARCA events occurred in children with heart disease and/or a history of cardiac surgery, those aged younger than one year, those with ASA physical status III‒V, and those who underwent emergency surgery. Many ARCA events were determined to be preventable. The implementation of specialized pediatric anesthesiology and training programs is crucial for anesthesia safety in children.

Junk food use and neurodevelopmental and growth outcomes in infants in low-resource settings.

Introduction: Feeding infants a sub-optimal diet deprives them of critical nutrients for their physical and cognitive development. The objective of this study is to describe the intake of foods of low nutritional value (junk foods) and identify the association with growth and developmental outcomes in infants up to 18 months in low-resource settings. Methods: This is a secondary analysis of data from an iron-rich complementary foods (meat versus fortified cereal) randomized clinical trial on nutrition conducted in low-resource settings in four low- and middle-income countries (Democratic Republic of the Congo, Guatemala, Pakistan, and Zambia). Mothers in both study arms received nutritional messages on the importance of exclusive breastfeeding up to 6 months with continued breastfeeding up to at least 12 months. This study was designed to identify the socio-demographic predictors of feeding infants' complementary foods of low nutritional value (junk foods) and to assess the associations between prevalence of junk food use with neurodevelopment (assessed with the Bayley Scales of Infant Development II) and growth at 18 months. Results: 1,231 infants were enrolled, and 1,062 (86%) completed the study. Junk food feeding was more common in Guatemala, Pakistan, and Zambia than in the Democratic Republic of Congo. 7% of the infants were fed junk foods at 6 months which increased to 70% at 12 months. Non-exclusive breastfeeding at 6 months, higher maternal body mass index, more years of maternal and paternal education, and higher socioeconomic status were associated with feeding junk food. Prevalence of junk foods use was not associated with adverse neurodevelopmental or growth outcomes. Conclusion: The frequency of consumption of junk food was high in these low-resource settings but was not associated with adverse neurodevelopment or growth over the study period.

Type and timing of ultra-processed foods consumption and its association with dietary intake and physical activity in women with obesity living in poverty.

BACKGROUND: The present study aimed to investigate the type and timing of ultra-processed foods (UPF) consumption and its association with dietary intake (DI) and physical activity (PA) in women with obesity living in poverty. METHODS: A cross-sectional study was employed. Obesity was defined by at least two criteria (body mass index, waist circumference or % fat mass). Poverty was defined as the three lowest classes of the Brazilian Economic Classification Criterion. PA was measured with triaxial accelerometers and DI was assessed with three 24-h dietary recalls. Foods were categorised according to the NOVA classification, with UPF classified into five subgroups, as well as the timing of consumption into six meals. RESULTS: In total, 56 adult women were included. Overall energy intake was 1653.21 (503.22) kcal/day. UPF intake was 21.62% (11.94%) kcal/day, being higher at breakfast (4.91% kcal/day), afternoon snack (5.39% kcal/day) and dinner (5.01% kcal/day). Only UPF subgroup 4 (sandwich biscuits, sweets, or treats) showed a positive association with energy intake (ß = 54.40 [27.6, 81.10] kcal/day) and a negative association with protein intake (ß = -0.31% [-0.48%, -0.14%] kcal/day). UPF consumption in morning (ß = -0.41% [-0.79%, -0.02%] kcal/day) and afternoon (ß = -0.18% [-0.33%, -0.04%] kcal/day) snacks was associated with lower protein intake. Furthermore, lunchtime UPF consumption was positively associated with walking time (ß = 0.16% [0.02%; 0.30%]) and steps/hour (ß = 8.72 [1.50; 15.94] steps/h). CONCLUSIONS: Women with obesity living in poverty consume more UPF during breakfast, afternoon snack and dinner. Physical activity is positively associated with UPF consumption at lunch. UPF, such as sandwich biscuits, sweets or treats, contribute to increasing energy intake and reducing protein intake.

Continuing Professional Development at Two Rural Hospitals in Ecuador.

Background: E-learning Continuing Professional Development (CPD) is an activity demonstrated to improve the quality of healthcare delivery. The CPD of medical and nursing staff in high income countries (HICs) is commonplace. CPD of administrative staff is less common, but increasingly frequent. In low- and middle-income countries (LMICs), CPD of any kind is infrequent, particularly in rural and remote areas. Objective: The aim of this study was to describe a hospital-based e-learning CPD program for clinical and non-clinical personnel as a unique example of a successful, ongoing educational pilot, quality improvement program involving a broad cohort of employees, in a country that does not require such activities. Methods: Using the online educational platform Chamilo, e-learning modules were created for eight groups including clinical and non-clinical employees. Upon completion of each module, one to two paragraph discussions were provided for each incorrect answer submitted. Two additional chances were offered for the employee to achieve a passing score of 70%. This study reports on the first 10-month period of the program. Findings: All participants achieved the 70% passing threshold after the first or second attempt. There was 100% participation by the employees required to complete the e-learning modules. Employee feedback suggested the modules were good for continuing education, but some felt the CPD was imposed on them. Conclusion: E-learning CPD is an important and emerging element for CPD and may provide opportunities for healthcare service quality improvement as part of broader pedagogical modalities, such as conferences and directed readings, in rural and remote areas of LMICs. These pilot programs could provide important information to develop Spanish-language e-learning CPD programs across a broader region, promote collaboration with regional professional societies, and possibly contribute to the establishment of national health program CPD standards.

The Importance of Conducting Practice-oriented Research with Underserved Populations.

There has been a growing emphasis on dissemination of empirically supported treatments. Dissemination, however, should not be restricted to treatment. It can and, in the spirit of the scientific-practitioner model, should also involve research. Because it focuses on the investigation of clinical routine as it takes place in local settings and because it can involve the collaboration of several stakeholders, practice-oriented research (POR) can be viewed as an optimal research method to be disseminated. POR has the potential of addressing particularly relevant gaps of knowledge and action when implemented in regions of the world that have limited resources for or experiences with empirical research, and/or in clinical settings that are serving clinical populations who are not typically receiving optimal mental care services - specifically, individuals in rural and inner cities that have limited economic and social resources. The establishment and maintenance of POR in such regions and/or settings, however, come with specific obstacles and challenges. Integrating the experiences acquired from research conducted in various continents (Africa, Europe, Latin America, and North America), the goal of this paper is to describe some of these challenges, strategies that have been implemented to address them, as well as new possible directions to facilitate the creation and growth of POR. It also describes how these challenges and ways to deal with them can provide helpful lessons for already existing POR infrastructures.

Digital Support Systems to Improve Child Health and Development in Peru: Protocol for a Randomized Controlled Trial.

BACKGROUND: Children living in low and middle-income countries (LMICs) are at greater risk for experiencing adversities that can undermine their health and early development. Recently launched digital early childhood development (ECD) programs attempt to support families with young children in their home environments using digital technologies. However, relatively little is known regarding the effectiveness of these new technologies. OBJECTIVE: The goal of this study is to rigorously assess the reach, effectiveness, and cost-effectiveness of a newly developed digital ECD platform called Afini. The Afini platform was designed to support parents of young children in low-resource settings to improve ECD and interact with caregivers through messenger services and a chatbot. METHODS: This is a 3-arm cluster randomized controlled trial. In total, 2471 caregivers and their 3- to 9-month-old children were enrolled in the study across 164 study clusters in the San Marcos, Cajabamba, and Cajamarca provinces of Peru. Clusters of participants were randomly assigned to 1 of 3 groups: a control group (72 community clusters and 980 caregiver-child dyads), a home visit intervention group (20 community clusters and 316 caregiver-child dyads), and an Afini intervention group (72 community clusters and 1175 caregiver-child dyads). Families in the control group receive no focused ECD intervention. The home visit group is receiving biweekly home visits by a trained field staff following the national ECD program (Programa Nacional Cuna Más) curriculum and training guidelines. Caregivers in the Afini group are receiving ECD activities and advice through the digital platform. The primary study outcome is children's overall development at the age of 2.5 years, using the internationally validated long form of the Global Scales for Early Development. Secondary outcomes include caregiver engagement; caregiver mental health; screen time; as well as caregiver reports of children's motor, cognitive, language, and socioemotional development measured through locally piloted and validated tools. RESULTS: Enrollment started in September 2021 and ended in March 2023. Endline assessments will take place between August 2023 and September 2024. CONCLUSIONS: This study is, to our knowledge, the first to rigorously assess the effectiveness and cost-effectiveness of digital ECD technologies in LMICs. Given the large number of children in LMICs currently receiving only limited external support, the evaluated platform has the potential to improve the short- and long-term well-being of millions of children and their parents globally.

Demanda de servicios de salud de la población adulta mayor de bajos ingresos en Colombia

Objetivo: Analizar los determinantes de la demanda de servicios de salud del adulto mayor entre los segmentos más pobres de Colombia. Materiales y métodos: Estudio de datos panel a partir de datos de riesgo individualizado de una aseguradora del régimen subsidiado en Colombia. Se elaboraron modelos de regresión lineal para determinar la demanda de salud bajo dos escenarios. Resultados: El hacinamiento, la exposición al humo y roedores mantienen una relación positiva con la demanda de servicios de salud. Por el contrario, la educación, ocupación, realizar actividad física y el no consumo de alcohol son factores protectores. Conclusión: La transición demográfica y epidemiológica que experimenta Colombia trae consigo retos para el sistema de salud. La identificación de determinantes de la demanda contribuye al establecimiento de estrategias para el mejoramiento del sistema de salud vigente y futuro.

Objective: To analyze the determinants of the demand for health services of the elderly among the poorest segments in Colombia. Materials and methods: Panel data study based on individualized risk data from an insurer of the subsidized regime in Colombia. Linear regression models were developed to determine health demand under two scenarios. Results: Overcrowding, exposure to smoke and rodents maintain a positive relationship with the demand for health services. On the contrary, education, occupation, physical activity, and non-alcohol consumption are protective factors. Conclusion: The demographic and epidemiological transition that Colombia is experiencing brings challenges to the health system. The identification of determinants of demand contributes to the implementation of strategies to improve the current and future health system.

Rabies outbreak in Brazil: first case series in children from an indigenous village.

BACKGROUND: Human rabies outbreak transmitted by bats continues to be a relevant public health problem not only in the Amazon region. The disease has affected one of the areas with the greatest poverty in southeastern Brazil, a region inhabited by the Maxakali indigenous people. CASE PRESENTATION: We describe four cases of rabies among indigenous children that occurred in the indigenous village of Pradinho, municipality of Bertópolis, Minas Gerais, Brazil. Cases were notified between April and May 2022, all of whom died on average eight days after the first symptoms. All cases were observed in rural residents under 12 years of age. The probable form of exposure was through bat bites. The predominant symptoms were prostration, fever, dyspnea, sialorrhea, tachycardia, and altered level of consciousness. Half of the cases underwent late and/or incomplete post-exposure rabies prophylaxis, however, the other half underwent pre-exposure rabies prophylaxis, with only one case completing the scheme and another undergoing the adapted Milwaukee Protocol (Recife Protocol). All cases ended in death. CONCLUSIONS: This was the first rabies outbreak among indigenous people in Brazil. Among the manifested clinical forms in the series, there was a disease atypical presentation in at least one case. We suggest active surveillance and an intercultural educational campaign to prevent new cases.

Maternal and perinatal health among pregnant patients in the context of a migratory crisis.

OBJECTIVE: To compare maternal and perinatal outcomes of migrant Venezuelan women with local pregnant patients in a Colombian institution in the context of a migratory crisis. STUDY DESIGN: This cross-sectional study included 11 304 deliveries from the Clínica de Maternidad Rafael Calvo in Cartagena de Indias, Colombia, a tertiary referral center on the north coast of Colombia. Data on maternal demographics and perinatal outcomes were obtained by chart review. RESULTS: In total, 595 patients were identified as Venezuelan migrants, and their perinatal outcomes were compared against those of 10 709 local pregnant patients. Despite similar baseline maternal conditions in both groups, poorer prenatal follow-up care (3 [1-5] vs. 5 [4-7] visits; P < 0.001) and severe complications were more common in Venezuelan migrant pregnant patients and their children. In addition, maternal hypertension was significantly more common in migrants (11.4% [68/595] vs. 8.3% [887/10709]; P = 0.009). Furthermore, in the group of pregnant migrant patients, the rates of severe maternal morbidity (13.4% [80/575] vs. 9.45%, [1013/10709]; P = 0.002), neonatal respiratory distress syndrome (22/595 [3.7%] vs. 237/10709 [2.23%]; P = 0.03), and perinatal mortality (11/586 [1.88%] vs. 67/10651 [0.63%]; P = 0.003) were significantly higher than in the local pregnant population. CONCLUSION: Forced migration during pregnancy may be associated with poorer prenatal care, which may predispose women and their newborns to more frequent adverse maternal and perinatal outcomes.

Mulheres de Bairros Populares em Caxias-MA: Vidas que (Re)Existem / Women From Low-Income Neighborhoods in Caxias-MA: Lives that Exist / Mujeres de Barrios Populares de Caxias-MA: Vidas que (Re) Existen

O presente estudo parte das experiências das mulheres nos bairros populares de uma cidade do interior do Maranhão, Caxias. Objetivou-se conhecer as histórias de vida das mulheres desses bairros, os seus modos de vida e resistência em suas vivencias diárias. Trata-se de uma pesquisa qualitativa que tem como base a produção de sentido no cotidiano. Participaram cinco mulheres de quatro bairros populares do município. Foram utilizadas a observação no cotidiano, conversas no cotidiano e entrevista semiestruturada. Para a análise foi utilizado o mapa dialógico de produção de sentidos. Percebeu-se que as mulheres atuam enquanto sujeitas ativas em seus bairros buscando por melhores condições de vida, em prol de educação e infraestrutura, a partir da formação de uma rede de sociabilidade e solidariedade, à frente de clube de mães, associação de moradores e grupo de dança enquanto formas de resistência. Logo, entende-se que esse estudo pode contribuir com a literatura e discussões sobre mulheres de contextos periféricos de regiões não metropolitanas.

The present study is based on the experiences of women from the low-income neighborhoods of Caxias, a country town in the Brazilian State of Maranhão. The purpose was to investigate the life stories of women who live in that neighborhoods, their ways of life, and resistance in their daily experiences. This is a qualitative research that is based on the production of meaning in everyday life. We have researched five women from four low-income neighborhoods in the city through daily observation, daily conversations, and semi-structured interviews. We have used the dialogic map of production of meaning for this analysis. It was noticed that women act as active subjects in their neighborhoods, looking for better living conditions towards education and infrastructure. They do it building a network of sociability and solidarity which includes a front of mothers' club, community association, and dance group as forms of resistance. Therefore, we realize that this study can contribute to the literature and to the discussion about women from peripheral contexts of non-metropolitan regions.

A WIC-Based Behavior Change Intervention for Postpartum Women With Overweight and Obesity: A Pilot Feasibility Randomized Trial.

Background. Postpartum weight retention is a risk factor for obesity and is particularly important among Hispanic women who have an increased rate of obesity. Given its broad reach, the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) program provides an ideal setting to implement community-based interventions for low-income postpartum women. Purpose. To examine the feasibility, acceptability, and preliminary efficacy of a multicomponent intervention delivered by staff within the WIC program designed to promote behavior changes in urban, postpartum women with overweight/obesity. Method. This was a 12-week pilot trial randomizing participants to a health behavior change (Intervention) or control (Observation) group. The Intervention included monthly visits with trained WIC staff providing patient-centered behavior change counseling, with multiple touchpoints between visits promoting self-monitoring and offering health behavior change support. Results. Participants (n = 41), who were mainly Hispanic (n = 37, 90%) and Spanish-speaking (n = 33, 81%), were randomized to the Intervention (n = 19) or Observation (n = 22) group. In the Intervention group, 79% (n = 15) of eligible participants were retained for the study duration. All Intervention participants endorsed that they would participate again. Regarding physical activity, participant readiness to change and self-efficacy improved for Intervention participants. About one-quarter of women in the Intervention group (27%, n = 4) had a 5% weight loss compared with one woman (5%) in the Observation group; this difference was not statistically significant (p = .10). Conclusions. This pilot demonstrated the feasibility and acceptability of delivering a low-intensity behavior change intervention within the WIC setting for postpartum women with overweight/obesity. Findings support the role of WIC in addressing postpartum obesity.

One Health Approach on Dog Bites: Demographic and Associated Socioeconomic Factors in Southern Brazil.

Despite being an important public health issue, particularly due to rabies, dog bites and associated risk factors have rarely been assessed by health services from a One Health perspective. Accordingly, the present study aimed to assess dog biting and associated demographic and socioeconomic risk factors in Curitiba, the eighth-largest Brazilian city with approximately 1.87 million people, based on the post-exposure prophylaxis (PEP) rabies reports between January/2010 and December/2015. The total of 45,392 PEP reports corresponded to an average annual incidence of 4.17/1000 habitants, mainly affecting white (79.9%, 4.38/1000 population), males (53.1%, 4.81/1000 population), and children aged 0-9 years (20.1%, 6.9/1000 population), with severe accidents associated with older victims (p < 0.001) and mainly caused by dogs known to the victims. An increase of USD 100.00 in the median neighborhood income was associated with a 4.9% (95% CI: 3.8-6.1; p < 0.001) reduction in dog bites. In summary, dog biting occurrence was associated with victims' low income, gender, race/color, and age; severe accidents were associated with elderly victims. As dog bites have been described as multifactorial events involving human, animal, and environmental factors, the characteristics presented herein should be used as a basis to define mitigation, control, and prevention strategies from a One Health perspective.

Association of development quotient with nutritional status of vitamins B6, B12, and folate in 6-59-month-old children: Results from the Brazilian National Survey on Child Nutrition (ENANI-2019).

BACKGROUND: Vitamins B6, B12, and folate are essential for the formation and maintenance of the human brain, but studies evaluating these vitamins with early childhood development (ECD) in children under 5 y are limited and controversial. OBJECTIVES: To evaluate the association between vitamins B6, B12, and folate concentrations/status and ECD. METHODS: Data regarding 6520 children aged 6-59 mo from the ENANI-2019 (the Brazilian National Survey on Child Nutrition) were analyzed. ECD was assessed using the Survey of Well-being of Young Children's milestones questionnaire. Vitamin B6 concentration (nmol/L) was classified according to the tertile of the distribution and with the cutoff <20 nmol/L. Folate concentrations >45.3 nmol/L were classified as high, and vitamin B12 <150 pmol/L was deficient. The graded response model was used to estimate developmental age, and the developmental quotient (DQ) was calculated as the developmental age divided by chronological age. Multiple linear regression models were adjusted for confounders. RESULTS: The DQ mean (95% confidence interval) for Brazilian children was 0.99 (0.97-1.01). Children aged 6-23 mo [1.13 (1.10-1.16)] had a higher DQ mean than those aged 24-35 [0.99 (0.95-1.03)] and 36-59 mo [0.89 (0.86-0.92)]. Child age was inversely associated with DQ (ß = -0.007; P < 0.001). An interaction between child age and vitamin B12 deficiency in the DQ (ß = -0.005; P < 0.001) indicated that, in children aged 36-59 mo, the DQ was markedly lower in children with vitamin B12 deficiency than in those without vitamin B12 deficiency. Vitamin B6 concentrations were directly associated with the DQ (ß = 0.0004; P = 0.031) among children aged 24-59 mo in the adjusted model. No association was observed between folate status and DQ. CONCLUSIONS: In Brazil, the DQ is lower among older children and those with vitamin B12 deficiency. Vitamin B6 status was directly associated with the DQ in children aged 24-59 mo.
