Association of Sociodemographic Factors and Maternal Educational Attainment with Child Development among Families Living below the Poverty Line in the State of Ceará, Northeastern Brazil.

Maternal educational attainment has been identified as relevant to several child health and development outcomes. This study aimed to evaluate the association of sociodemographic and maternal education factors with child development in families living below the poverty line. A cross-sectional study was conducted through telephone contact from May to July 2021 in Ceará, a state in Northeastern Brazil. The study population comprised families with children up to six years of age participating in the cash transfer program "Mais infância". The families selected to participate in this program must have a monthly per capita income of less than US$16.50. The Ages and Stages Questionnaire version 3 was applied to assess the children's development status. The mothers reported maternal educational attainment as the highest grade and or degree obtained. The final weighted and adjusted model showed that maternal schooling was associated with the risk of delay in all domains except for the fine motor domain. The risk of delay in at least one domain was 2.5-fold higher in mothers with a lower level of schooling (95% CI: 1.6-3.9). The findings of this study suggest that mothers with higher educational attainment have children with better child development outcomes.

Positive Parenting Behaviors and Child Development in Ceará, Brazil: A Population-Based Study.

Parenting practices have been identified as a key determinant of children's developmental outcomes. The aim of this study was to evaluate the association of parenting practices with child development in a cross-sectional population-based study in a low-income state in northeastern Brazil. The study included data on 3566 caregiver−child pairs, and the children were aged 0−66 months. Positive parenting behaviors (PPBs) were conceptualized in areas of interactive play, social development, and speech and language interactions. Child development was evaluated using the Brazilian Ages and Stages Questionnaire. Linear regression analysis was used to assess the relationships. We found that a greater number of PPBs was associated with better child development domain scores. Among infants < 1 year, each additional PPB was associated with a 0.32 standardized mean difference (SMD) greater communication (95% CI: 0.24−0.41) and 0.38 SMD greater problem-solving scores (95% CI: 0.24−0.52). Among children aged 4−6 years old, each additional PPB was associated with improved communication (SMD: 0.22; 95% CI: 0.13−0.32), problem solving (SMD: 0.21; 95% CI: 0.10−0.32) and personal−social domain scores (SMD: 0.26; 95% CI: 0.17−0.36). Our findings indicate that PPB were robustly associated with better outcomes across developmental domains among Brazilian children. Programs and interventions that support PPB can contribute to improvements in development outcomes.

Undernutrition and short duration of breastfeeding association with child development: a population-based study

Abstract Objective: To explore the relationship of undernutrition and the short duration of breastfeeding with child development of children 0-66 months of age residing in Ceará, Brazil. Methods: The authors of the present study utilized population-based data from children enrolled in the Study on Maternal and Child Health in Ceará, Brazi (PESMIC). Children's development was assessed with the Ages and Stages Questionnaire third version, validated in Brazil. Undernutrition was accessed through anthropometric measures obtained by trained staff. Breastfeeding information was obtained through the mothers' report and confirmed in the child's governmental booklet. The authors used logistic regressions adjusted for sample clusters used in PESMIC design in a theoretical model for known determinants of child development following the World Health Organization nurturing framework. Results: A total of 3,566 children were enrolled in the sixth PESMIC study and had their development assessed. The authors found that 8.2%, 3.0%, 2.1%, and 3.6% of children were stunted, underweight, or wasted, at the time of the interview, respectively. All studied factors were associated with a higher prevalence of child development impairment in at least one of the assessed domains. Underweight was the factor with the strongest effect, with an adjusted odds ratio (AOR) of 4,14 (2,26-7,58), p < 0.001. Breastfeeding for up to two months compared to more than six months (AOR2,08 (1,38-3,12)) was also associated. Conclusions: The authors found that undernutrition and short duration of breastfeeding are associated with development outcomes among Brazilian children. As a result, integrated nutritional programs may improve child development outcomes.

Maternal and neonatal factors associated with child development in Ceará, Brazil: a population-based study.

BACKGROUND: The first 1000 days of life are a critical period when the foundations of child development and growth are established. Few studies in Latin America have examined the relationship of birth outcomes and neonatal care factors with development outcomes in young children. We aimed to assess the association between pregnancy and neonatal factors with children's developmental scores in a cross-sectional, population-based study of children in Ceará, Brazil. METHODS: Population-based, cross-sectional study of children aged 0-66 months (0-5.5 years) living in Ceará, Brazil. We examined the relationship of pregnancy (iron and folic acid supplementation, smoking and alcohol consumption) and neonatal (low birth weight (LBW) gestational age, neonatal care interventions, and breastfeeding in the first hour) factors with child development. Children's development was assessed with the Ages and Stages Questionnaire (ASQ-BR). We used multivariate generalized linear models that accounted for clustering sampling to evaluate the relationship of pregnancy and neonatal factors with development domain scores. FINDINGS: A total of 3566 children were enrolled. Among pregnancy factors, children whose mothers did not receive folic acid supplementation during pregnancy had lower fine motor and problem-solving scores (p-values< 0.05). As for neonatal factors, LBW was associated with 0.14 standard deviations (SD) lower (CI 95% -0.26, - 0.02) communication, 0.24 SD lower (95% CI: - 0.44, - 0.04) fine motor and 0.31 SD lower (CI 95% -0.45, - 0.16) problem-solving domain scores as compared to non-LBW children (p values < 0.05). In terms of care, newborns that required resuscitation, antibiotics for infection, or extended in-patient stay after birth had lower development scores in selected domains. Further, not initiating breastfeeding within the first hour after birth was associated with lower gross motor and person-social development scores (p-values < 0.05). CONCLUSION: Pregnancy and neonatal care factors were associated with later child development outcomes. Infants at increased risk of suboptimal development, like LBW or newborns requiring extended in-patient care, may represent groups to target for supplemental intervention. Further, early integrated interventions to prevent adverse pregnancy and newborn outcomes may improve child development outcomes.

Adverse Childhood Experiences and Child Development Outcomes in Ceará, Brazil: A Population-based Study.

INTRODUCTION: More than 200 million children fail to reach their full developmental potential in low- and middle-income countries. Adverse childhood experiences, maternal mental health, and intimate partner violence are negatively associated with child development outcomes. The relationship of these risk factors with child communication, gross motor, fine motor, problem-solving, and personal-social development scores in Brazil are assessed. METHODS: A population-based, cross-sectional study of preschool children living in the state of Ceará, Brazil, in 2017 was conducted. Child development was assessed with the Ages and Stages Questionnaire. Adverse childhood experiences for children were self-reported by the participants' mothers using the Centers for Disease Control and Prevention Adverse Childhood Experiences Study‒adapted metric. Maternal mental health and intimate partner violence were evaluated using validated questionnaires. Sample-adjusted multivariable generalized linear models with interaction terms were used to determine the association of intimate partner violence, maternal mental health, and adverse childhood experiences with developmental outcomes and identify possible moderators. Data were analyzed between 2019 and 2020. RESULTS: Children exposed to ≥3 adverse childhood experiences had -0.12 (95% CI= -0.24, 0) lower communication, -0.25 (95% CI= -0.46, -0.03) lower gross motor, -0.27 (95% CI= -0.47, -0.07) lower fine motor, and -0.17 (95% CI= -0.3, -0.03) lower personal-social domain scores than children with no adverse childhood experiences. Furthermore, the greater number of adverse childhood experiences was linearly associated with lower developmental scores. Maternal mental health and intimate partner violence were also associated with lower development scores. CONCLUSIONS: Adverse childhood experiences were independently associated with developmental outcomes in Brazilian children. Community-based interventions to reduce the impact of adverse childhood experiences, intimate partner violence, and maternal mental health may benefits child development outcomes.

Environmental, Socioeconomic, Maternal, and Breastfeeding Factors Associated with Childhood Overweight and Obesity in Ceará, Brazil: A Population-Based Study.

Childhood obesity is now an epidemic in many countries worldwide and is known to be a multifactorial condition. We aimed to examine the relationship of environmental, socioeconomic, and nutritional factors with childhood overweight and obesity. We conducted a population-based cross-sectional study of children from 2 to 6 years of age in Ceará, Brazil. Children's nutritional status was assessed by body mass index (BMI) Z scores categorized as overweight and obesity. Ordinal logistic regression models were used to assess the relationship between the factors with overweight and obesity. A total of 2059 children participated, of which 50.4% were male. The mean age was 46 ± 17 months, with a prevalence of overweight and obesity of 12.0% (95% CI 10.7-13.6) and 8.0% (6.7-9.5), respectively. In multivariate analysis, the probability of childhood obesity increased as family income increased (adjusted hazard ratio (aHR) 0.6 (95% CI 0.37-0.95), p-value = 0.03). Moreover, families with fewer children had more than 30% fewer overweight children (aHR 0.68; 95% CI 0.48-0.96). Environmental, socioeconomic, and child nutritional factors were associated with overweight and obesity. The results provided could be used to design integrated interventions spanning from conception, or earlier, through the first years of life and may improve child nutritional outcomes.

Bioactive Hydrogel Marbles.

Liquid marbles represented a significant advance in the manipulation of fluids as they used particle films to confine liquid drops, creating a robust and durable soft solid. We exploit this technology to engineering a bioactive hydrogel marble (BHM). Specifically, pristine bioactive glass nanoparticles were chemically tuned to produce biocompatible hydrophobic bioactive glass nanoparticles (H-BGNPs) that shielded a gelatin-based bead. The designed BHM shell promoted the growth of a bone-like apatite layer upon immersion in a physiological environment. The fabrication process allowed the efficient incorporation of drugs and cells into the engineered structure. The BHM provided a simultaneously controlled release of distinct encapsulated therapeutic model molecules. Moreover, the BHM sustained cell encapsulation in a 3D environment as demonstrated by an excellent in vitro stability and cytocompatibility. The engineered structures also showed potential to regulate a pre-osteoblastic cell line into osteogenic commitment. Overall, these hierarchical nanostructured and functional marbles revealed a high potential for future applications in bone tissue engineering.

Strontium-Doped Bioactive Glass Nanoparticles in Osteogenic Commitment.

The present work has explored bioactive glass nanoparticles (BGNPs) and developed strontium-doped nanoparticles (BGNPsSr), envisioning orthopedic strategies compatible with vascularization. The nanoparticles were synthesized by the sol-gel method, achieving a diameter of 55 nm for BGNPs and 75 nm for BGNPsSr, and the inclusion of strontium caused no structural alteration. The nanoparticles exhibited high cytocompatibility for human umbilical vein endothelial cells (HUVECs) and SaOS-2. Additionally, the incorporation of strontium emphasized the tubule networking behavior of HUVECs. Our results demonstrate that the nanoparticle dissolution products encouraged the osteogenic differentiation of human adipose stem cells as it favored the expression of key genes and proteins associated with osteogenic lineage. This effect was markedly enhanced for BGNPsSr, which could prompt stem cell osteogenic differentiation without the typical osteogenic inducers. This study not only supports the hypothesis that BGNPs might play a significant role in osteogenic commitment but also highlights that the designed BGNPsSr is a valuable tool for stem cell "tune-up" in bone tissue engineering applications.

The potential of cashew gum functionalization as building blocks for layer-by-layer films.

Cashew gum (CG), an exudate polysaccharide from Anacardium occidentale trees, was carboxymethylated (CGCm) and oxidized (CGO). These derivatives were characterized by FTIR and zeta potential measurements confirming the success of carboxymethylation and oxidation reactions. Nanostructured multilayered films were then produced through layer-by-layer (LbL) assembly in conjugation with chitosan via electrostatic interactions or Schiff bases covalent bonds. The films were analyzed by QCM-D and AFM. CG functionalization increased the film thickness, with the highest thickness being achieved for the lowest oxidation degree. The roughest surface was obtained for the CGO with the highest oxidation degree due to the predominance of covalent Schiff bases. This work shows that nanostructured films can be assembled and stabilized by covalent bonds in alternative to the conventional electrostatic ones. Moreover, the functionalization of CG can increase its feasibility in multilayers films, widening its potential in biomedical, food industry, or environmental applications.

Bioplotting of a bioactive alginate dialdehyde-gelatin composite hydrogel containing bioactive glass nanoparticles.

Alginate dialdehyde-gelatin (ADA-GEL) constructs incorporating bioactive glass nanoparticles (BGNPs) were produced by biofabrication to obtain a grid-like highly-hydrated composite. The material could induce the deposition of an apatite layer upon immersion in a biological-like environment to sustain cell attachment and proliferation. Composites were formulated with different concentrations of BGNPs synthetized from a sol-gel route, namely 0.1% and 0.5% (w/v). Strontium doped BGNPs were also used. EDS analysis suggested that the BGNPs loading promoted the growth of bone-like apatite layer on the surface when the constructs were immersed in a simulated body fluid. Moreover, the composite constructs could incorporate with high efficiency ibuprofen as a drug model. Furthermore, the biofabrication process allowed the successful incorporation of MG-63 cells into the composite material. Cells were distributed homogeneously within the hydrogel composite, and no differences were found in cell viability between ADA-GEL and the composite constructs, proving that the addition of BGNPs did not influence cell fate. Overall, the composite material showed potential for future applications in bone tissue engineering.

Factors associated with non-vaccination against measles in northeastern Brazil: Clues about causes of the 2015 outbreak.

Measles is a highly contagious disease that can be effectively prevented through vaccination. The recent increase in vaccination coverage was successful in reducing the mortality globally of the disease by 74%. As a whole, the Americas have been considered a disease-free zone. However, it is known that if an immunization programs fails, there will be an accumulation of susceptible people that can lead to disease outbreaks. Recently, both the United States and Brazil faced outbreaks of measles. The present study aims to identify the determining factors of non-vaccination in Brazil in two different vaccination coverage moments, to provide clues as to the causes of current outbreaks. Data were drawn from five population-based cross-sectional studies that surveyed a representative sample of preschool children from 1987 to 2007 (9585 children in total). To assess children's vaccination status, two different information sources were used: information provided by mothers and information from children's health cards. Multivariate analyses with logistic binary regression models were conducted. After adjustment for confounding factors, it was observed that in 1987, with 48.2% vaccination coverage, socioeconomic, maternal, nutritional factors and access to health facilities were important, while in 2007 (96.7% coverage), nutritional and maternal factors were important. Distinct patterns of determinants of non-vaccination were also found. In addition, the low coverage in 1987 resulted in a current pool of adults who were not immunized as children; this may have contributed to the beginning of the current Brazilian outbreak. Globally, there are two standards of vaccination coverage (low and high). Therefore, discussion of the determinants of non-vaccination is important. Our findings suggest vulnerable groups should receive special attention to ensure they are protected. It is also important to consider the possible impact of pools of adults not immunized.

Chitosan/bioactive glass nanoparticles scaffolds with shape memory properties.

We propose a combination of chitosan (CHT) with bioactive glass nanoparticles (BG-NPs) in order to produce CHT/BG-NPs scaffolds that combine the shape memory properties of chitosan and the biomineralization ability of BG-NPs for applications in bone regeneration. The addition of BG-NPs prepared by a sol-gel route to the CHT polymeric matrix improved the bioactivity of the nanocomposite scaffold, as seen by the precipitation of bone-like apatite layer upon immersion in simulated body fluid (SBF). Shape memory tests were carried out while the samples were immersed in varying compositions of water/ethanol mixtures. Dehydration with ethanol enables to fix a temporary shape of a deformed scaffold that recovers the initial geometry upon water uptake. The scaffolds present good shape memory properties characterized by a recovery ratio of 87.5% for CHT and 89.9% for CHT/BG-NPs and a fixity ratio of 97.2% for CHT and 98.2% for CHT/BG-NPs (for 30% compressive deformation). The applicability of such structures was demonstrated by a good geometrical accommodation of a previously compressed scaffold in a bone defect. The results indicate that the developed CHT/BG-NPs nanocomposite scaffolds have potential for being applied in bone tissue engineering.

Prevalence and risk factors associated with wheezing in the first year of life / Prevalência e fatores de risco associados à sibilância no primeiro ano de vida

OBJECTIVE: to investigate the prevalence and risk factors associated with wheezing in infants in the first year of life. METHODS: this was a cross-sectional study, in which a validated questionnaire (Estudio Internacional de Sibilancias en Lactantes - International Study of Wheezing in Infants - EISL) was applied to parents of infants aged between 12 and 15 months treated in 26 of 85 primary health care units in the period between 2006 and 2007. The dependent variable, wheezing, was defined using the following standards: occasional (up to two episodes of wheezing) and recurrent (three or more episodes of wheezing). The independent variables were shown using frequency distribution to compare the groups. Measures of association were based on odds ratio (OR) with a confidence interval of 95% (95% CI), using bivariate analysis, followed by multivariate analysis (adjusted OR [aOR]). RESULTS: a total of 1,029 (37.7%) infants had wheezing episodes in the first 12 months of life; of these, 16.2% had recurrent wheezing. Risk factors for wheezing were family history of asthma (OR = 2.12; 95% CI: 1.76-2.54) and six or more episodes of colds (OR = 2.38; 95% CI: 1.91-2.97) and pneumonia (OR = 3.02; 95% CI: 2.43-3.76). For recurrent wheezing, risk factors were: familial asthma (aOR = 1.73; 95% CI: 1.22-2.46); early onset wheezing (aOR = 1.83; 95% CI: 1.75-3.75); nocturnal symptoms (aOR = 2.56; 95% CI: 1.75-3.75), and more than six colds (aOR = 2.07; 95% CI 1.43- .00). CONCLUSION: the main risk factors associated with wheezing in Fortaleza were respiratory infections and family history of asthma. Knowing the risk factors for this disease should be a priority for public health, in order to develop control and treatment strategies. .

Hospital mortality rates of infants with birth weight less than or equal to 1.500 g in the northeast of Brazil

OBJETIVO: Obter informações sobre a mortalidade de recém-nascidos com peso de nascimento menor ou igual a 1.500 g em Fortaleza e comparar com a Rede Vermont Oxford, uma das melhores referências de cuidados neonatais. MÉTODOS: Estudo de coorte prospectivo. Incluídos todos os recém-nascidos com peso de nascimento menor ou igual a 1.500 g em Fortaleza no período de 01/03/02 a 28/02/03 em todos os hospitais-maternidades com unidade de terapia intensiva neonatal. Os recém-nascidos foram seguidos do nascimento até a alta domiciliar ou morte hospitalar, utilizando o questionário da Rede Vermont Oxford. RESULTADOS: Foram analisados 774 recém-nascidos. O coeficiente de mortalidade neonatal foi de 477‰, e o coeficiente de mortalidade pós-neonatal foi de 35‰, elevando o coeficiente de mortalidade hospitalar total para 512‰. O coeficiente de mortalidade neonatal precoce foi de 335‰, e o coeficiente de mortalidade neonatal tardio foi de 142‰. Para todas as faixas de peso, os coeficientes de mortalidade em Fortaleza foram superiores aos da rede Vermont Oxford e também aos de Montevidéu, excetuando-se a faixa de peso menor ou igual a 600 g. CONCLUSÕES: Os resultados mostram elevadas taxas de mortalidade hospitalar de recém-nascidos de muito baixo peso com uma maior concentração na primeira semana de vida, sugerindo tanto deficiência na assistência prestada nas unidades de terapia intensiva neonatal quanto na atenção antenatal e no momento do parto.

OBJECTIVE: To obtain information on the hospital mortality of infants born in Fortaleza with birth weight less than or equal to 1,500 g, and to compare it with data from the Vermont Oxford Network, a center of excellence for neonatal care. METHODS: Prospective cohort study, enrolling all infants with birth weight less than or equal to 1,500 g born in Fortaleza between March 1, 2002 and February 28, 2003 from all the hospitals and maternity units with neonatal intensive care units. Infants were followed from birth until hospital discharge or hospital death, using the Vermont Oxford Network questionnaire.. RESULTS: A total of 774 newborn infants were analyzed. The neonatal mortality coefficient was 477‰, and the postneonatal mortality coefficient was 35‰, taking the hospital mortality coefficient to 512‰. The coefficient of early neonatal mortality was 335‰, and the coefficient of late neonatal mortality was 142‰. Mortality coefficients were higher in Fortaleza for all weight ranges than on the Vermont Oxford Network and were also, with the exception of the less than or equal to 600 g weight range, higher than in Montevideo. CONCLUSIONS: The results demonstrate high rates of hospital mortality among very low birth weight infants, with a greater concentration during the first week of life, suggesting that not only the care provided at the neonatal intensive care units is deficient, but also that prenatal and delivery-room care is inadequate.

Effectiveness of home-based peer counselling to promote breastfeeding in the northeast of Brazil: a randomized clinical trial.

AIMS: To evaluate the effectiveness of home-based peer counselling to increase breastfeeding rates for unfavourably low birthweight babies. METHODS: Randomized clinical trial carried out in maternity hospitals and households in Fortaleza, one of the regions in Brazil with very low income; 1003 mothers and their newborns were selected in eight maternity hospitals. Newborns needed were healthy and weighed less than 3000 g. INTERVENTION: Breastfeeding counselling, conducted by lay counsellors from the community, during home visits carried out on days 5, 15, 30, 60, 90 and 120 after birth. MAIN OUTCOME MEASURE: Feeding methods in the fourth month of life. RESULTS: The intervention increased exclusive breastfeeding (24.7% vs 19.4%; p=0.044), delayed the introduction of formula and increased the time infants substituted breastfeeding to bottle milk (bottle milk 33.4% in the control group and 20.1% in the intervention group; p=0.00002). When comparing the frequency of artificial breastfeeding versus all other forms of breastfeeding (exclusive+predominant+partial), the intervention increased breastfeeding rates in 39% (RR=0.61; CI 95%: 0.50-0.75); 15% of children were free from artificial feeding (absolute risk reduction). The number of families to be visited to avoid one child receiving artificial feeding (NNT) was 7 (CI 95%: 5-13). CONCLUSIONS: Breastfeeding counselling, promoted by lay counsellors, can impact favourably on exclusive breastfeeding rates and contribute to delaying the utilization of milk formula and weaning. The intervention has great application potential because most cities in the northeast of Brazil count on community health workers that could do the counselling.
