Factors associated with early childhood development in municipalities of Ceará, Brazil: a hierarchical model of contexts, environments, and nurturing care domains in a cross-sectional study

Factors associated with children's cognitive, language, and motor development in deprived urban settings in Bangladesh

BACKGROUND

Children's development is multifactorial. Although there have been several studies exploring the association of children's development with maternal, child, and environmental factors, we are unaware of any study that assessed those factors in children whose mothers were enrolled in a social safety net programme in low- and middle-income countries. This study aimed to identify the factors associated with disadvantaged children's cognitive, language, and motor development at age 6-16 months in deprived settings of urban Bangladesh and to identify relative importance of these factors of children's development. We also explored if there were any gender differences in child development.

METHODS

This cross-sectional study was conducted in a deprived setting of urban Bangladesh. Bayley III was used for assessing children's cognitive, language, and motor development. Multivariable linear regression model was used to find the factors associated with children's development, and dominance analysis was used to explore the relative importance of the factors.

RESULTS

Out of the total 599 mother-child dyads, 303 (50.58%) were girls. The factors associated with children's development were length-for-age Z-score (cognitive: B = 1.21 [95% CI = 0.31, 2.11], P = 0.008; language: 1.67 [0.79, 2.55] P < 0.001; motor: 2.15 [1.01, 3.29] P < 0.001) and home environment (cognitive: 0.58 [0.27, 0.89] P < 0.001; language: 0.59 [0.27, 0.92], P < 0.001; motor: 0.44 [0.09, 0.79] P = 0.013). Girls had higher cognitive (1.90 [0.17, 3.6], P = 0.031) and language (2.53 [0.55, 4.51], P = 0.013) development compared with boys. Families with a higher number of under five children within the households had lower language (-1.57 [-2.78, -0.36], P = 0.011) development. Violence against the mother and the families' food security status were not associated with the children's development. Children's length-for-age Z-score (27%) and home stimulation environment (23%) were the most important factors of cognitive development.

CONCLUSION

Children's nutritional status and home environment are important factors for disadvantaged children's development in deprived urban settings of Bangladesh. Both early child development-focussed parenting and nutrition interventions should be considered when designing child development programmes in urban settings in low- and middle-income countries.

Reading, singing, and storytelling: the impact of caregiver-child interaction and child access to books and preschool on early childhood development in Ghana

Optimal early childhood development (ECD) is crucial in shaping future academic and economic accomplishments. Recognising its profound influence, the United Nations has included a specific target and indicator related to ECD in the Sustainable Development Goals to ensure universal access to high-quality ECD for all preschoolers by 2030. This study investigated whether caregiver-child engagements, early stimulation, and learning opportunities are associated with ECD among children aged 36-59 months. Data on 6752 children were pooled from the 2011 and 2017 Ghana Multiple Indicator Cluster Surveys. The ECD outcomes of interest were literacy-numeracy, social-emotional, learning-cognitive, and physical development, measured with UNICEF's Early Childhood Development Index (ECDI). Binary logistic regression assessed the effects of various caregiver-child engagements and early learning opportunities on the ECD outcomes. We found that most children were developmentally on track in the physical (95.0%) and learning-cognitive (86.4%) domains, but fewer were on track in the literacy-numeracy (36.7%) and social-emotional (68.6%) domains. Reading to or with a child (aOR 1.72; 95% CI 1.35-2.19), telling them stories (aOR 1.61; 95% CI 1.26-2.04), counting or drawing with them (aOR 1.63; 95% CI 1.30-2.04) and a child's attendance at preschool (aOR 4.62; 95% CI 3.34-6.38) were associated with a higher odds for on track literacy-numeracy development. Playing with a child was associated with higher odds of on-track social-emotional development (aOR 1.29; 95% CI 1.04-1.59), physical development (aOR 1.61; 95% CI 1.01-2.55), and learning-cognitive development (aOR 1.51; 95% CI 1.14-2.00). However, singing songs to or with a child (aOR 0.78; 95% CI 0.62-0.89) and taking a child outside the home (aOR 0.78; 95% CI 0.64-0.95) were associated with lower odds for on track social-emotional development. Access to children's books at home was associated with higher odds for on track literacy-numeracy and social-emotional development. In subgroup analysis, some observed associations varied depending on a child's residence (urban or rural). Our findings confirmed that caregiver-child  interaction and early learning opportunities could increase a child's likelihood of achieving early developmental milestones.

Studies on the Child Handbook in Brazil: a scoping review

OBJECTIVE

To systematically identify and map studies involving the Caderneta da Criança (Child Handbook - CH) in Brazil.

METHODS

A scoping review using the methodology proposed by the Joanna Briggs Institute. The databases PubMed, Biblioteca Virtual em Saúde (BVS), Biblioteca Digital Brasileira de Teses e Dissertações, Periódicos Capes and Google Scholar were consulted. Primary and secondary studies that mentioned the use of CH were included, without restrictions regarding design, year of publication or population, published in Portuguese, English or Spanish and gray literature (theses and dissertations).

RESULTS

A total of 129 studies were included, mostly descriptive, published as scientific papers. The Northeast region, the population of caregivers of children and the Primary Care scenario were observed in most studies; 47% of the studies used the CH as a source of data, the majority on vaccination. Despite the different criteria to define adequacy of completing the CH, the studies identified weaknesses in filling out all of its items, except for immunization. The utilization and/or completion of the CH were linked to various factors, including the availability of the CH, characteristics of the children (such as sex, age, prematurity and well-child appointments), attributes of the family members and caregivers (such as age, education, income, parity, work status, prenatal care, reading, note-taking and bringing CH to appointments) and features of the professionals (such as workplace, medical specialty, communication style, knowledge about the CH, requesting, guiding and note-taking).

CONCLUSIONS

The results reinforce the need to better understand which factors affect the distribution of the CH in the population, as well as pointing to the need for understanding its use and completion by the different care points. The need for intervention studies to improve the implementation of this tool and to include training on the use of the CH in the context of continuing health education becomes evident.

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 five are limited and controversial.

OBJECTIVE

To evaluate the association between vitamins B6, B12, and folate concentrations/status and ECD.

METHODS

Data regarding 6,520 children aged 6-59 months (from the Brazilian National Survey on Child Nutrition [ENANI-2019]) 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 as 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 months (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 months (0.89 [0.86-0.92]). Child age was inversely associated with DQ (β=-0.007; p<0.001). An interaction between child age and vitamin B12 deficiency in the DQ (β=-0.005; p<0.001) indicated that, in children aged 36-59 months, the DQ was markedly lower in children with B12 deficiency than in those without B12 deficiency. Vitamin B6 concentrations were directly associated with the DQ (β=0.0004; p=0.031) among children aged 24-59 months 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 months.

Expectant mothers and fathers' knowledge of nurturing care in a developing country

BACKGROUND

The Nurturing Care Framework (NCF), which has been emphasized by the World Health Organization (WHO) in recent years and is among the United Nations Sustainable Development Goals (SDGs), expresses the conditions created to promote early childhood development (ECD). These conditions aim to provide opportunities for children in the Good Health, Adequate Nutrition, Responsive Caregiving, Security and Safety, and Opportunities for Early Learning (5 Components) by caregivers, primarily from low and middle-income countries (LMICs). The aim of this study is to examine the knowledge and awareness of expectant mothers and fathers in Turkey, about the NCF.

METHODS

In this study, a cross-sectional, analytical research design was used. Nurturing Care (NC) knowledge and awareness levels of expectant mothers and fathers in the 2nd and 3rd trimesters of pregnancy were determined via the online form of "The Knowledge of Nurturing Care Inventory (KNCI)" prepared by the researchers. This form consists of 60 questions describing the 5 components mentioned above. The sample contains a total of 103 people, 91 (88.3%) women, and 12 (11.7%) men.

RESULTS

Among the findings, the highest mean of knowledge level (13.76 ± 1.22) was found in Responsive Caregiving, and the lowest mean of knowledge level (4.35 ± 1.83) was found in Opportunities for Early Learning. The general level of knowledge on NC was found to vary statistically significantly depending on gender in favor of the women [t(101) = 3.27, p < .05], depending on educational status in favor of those with university and graduate education [F(2, 100) = 3.481, p < .05], depending on participation in pregnancy school training in favor of those who attended [t(101) = 2.349, p < .05], and depending on knowledge on how to support development in favor of those who know how to support [t(101) = 2.370, p < .05].

CONCLUSIONS

As a result, expectant parents need information and support about the period when children can acquire the basic developmental milestones and about the developmental risk indicators. More research is needed to implement the NCF starting from the preconception period, especially in LMICs, so that the opportunities in early childhood (which is the time period when the brain architecture is shaped, and development is the fastest) are not missed.
