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.

Coronavirus disease 2019, food security and maternal mental health in Ceará, Brazil: a repeated cross-sectional survey.

OBJECTIVE: To quantify the change in the risk of food insecurity and maternal mental disorder (MMD) before and during the coronavirus disease 2019 (COVID-19) pandemic. DESIGN: Repeated cross-sectional survey. Between 17 July and 10 September 2020, mother-child pairs who were enrolled in a population-based survey in 2017 were re-contacted by telephone for consent and to complete a telephonic COVID-19 survey. We used the Brazilian Food Insecurity Scale to assess food security and the Self Reporting Questionnaire-20 to assess MMD. McNemar's test for paired data that also accounted for clustering was used. Logistic regression was used to assess the relationship of unemployment and receipt of government assistance with food insecurity and MMD in 2020. SETTING: Ceará, Brazil. PARTICIPANTS: Five hundred and seventy-seven mother-child pairs completed the 2017 and 2020 surveys. At the time of the 2020 interview, the child cohort was 36-108 months of age. RESULTS: The proportion of mothers reporting food insecurity was 15·5 % higher (95 % CI 5·9, 25·1, P value < 0·001) during the pandemic in July-August 2020 as compared with November 2017, while the prevalence of MMD was 40·2 % higher during the pandemic (95 % CI 32·6, 47·8, P value < 0·001). Loss of formal employment was associated with increased risk of food insecurity, but not with the risk of MMD. CONCLUSIONS: The risk of food insecurity and MMD in Ceará increased during the COVID-19 pandemic. These findings highlight the need for policies and interventions to reduce the impact of the COVID-19 pandemic on maternal and child health, nutrition and well-being in Brazil.

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.

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.
