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.

Background

Although sustainable development goals mandate for quality early childhood development (ECD) interventions for children <8 years, little occurs for children <3 years, especially in urban settings in low-and-middle-income countries (LMICs). Our primary objective was to measure the effect of an ECD-focused parenting and nutrition education on children's development through home visits using a social safety net platform of urban Bangladesh.

Methods

A cluster randomized controlled trial was conducted with mothers of children aged 6–16 months in 20 clusters across the Rangpur city, Bangladesh. The intervention group received fortnightly ECD-focused parenting and nutrition education at homes by local Community Health Workers (CHWs) for one year. Bayley-III was used to measure children's cognitive, language and motor development. Data were analyzed using intention to treat. ClinicalTrials.gov Identifier: NCT03753646.

Findings

Out of 599 mother-child dyads, 56.6% mothers were aged ≤25 years old. After one year, the intervened children had higher cognitive [Effect size Cohen's d; 0.42 SD (95% CI: 0.58–0.25)], language (0.38 SD, 95% CI: 0.55–0.22) and motor (0.17 SD, 95% CI: 0.01–0.34) development. In the intervention group, mothers experienced less violence [Odds ratio; 0.6 (95% CI: 0.4–1.0)] and fathers engaged more (0.23 SD, CI: 0.39–0.06) in ECD activities with their children compared to the comparison group. Total home stimulation and mothers' knowledge on child care were also improved in the intervention. But the children's growth was not improved.

Interpretation

This ECD programme improves the development of children of young mothers in urban settings using a social safety-net platform. The evidence may help in increasing ECD coverage in urban areas in LMICs.

Background

Maternal post-natal depression is a global public health problem. Parenting interventions targeting children’s development may also bring benefits to mothers, but few parenting interventions have been studied thoroughly.

Objectives

The study aimed to measure the effect of a parenting intervention using culturally appropriate and locally made toys, along with nutrition education and unconditional cash, on maternal depressive symptoms (MDS) and quality of life (QoL).

Methods

The study was a cluster randomised controlled trial with two arms: i) intervention: parenting with nutrition education and unconditional cash and ii) comparison: unconditional cash in an urban setting in Bangladesh. Twenty clusters were randomised to either the intervention or control group. Community Health Workers (CHWs) delivered parenting and nutrition education sessions fortnightly in households for one year. The participants were mother-child (6–16 months) dyads. The MDS and QoL were measured using the Self-Reporting Questionnaire-20 and a brief version of the QoL questionnaire. Linear regression analysis was used to assess the treatment effects.

Results

After one year of intervention, 547 mothers (93%) completed the study. The mothers in the intervention group had lower MDS [Regression coefficient (β)=-1.53, Confidence interval (95% CI)=-2.28, −0.80] and higher QoL scores in physical health [β = 4.21 (95% CI = 1.71, 6.73)], psychological health [β = 3.14 (95% CI = 1.10, 5.19)], social relationships [β = 3.21 (95% CI = 0.76, 5.66)] and environment [β = 3.40 (95% CI = 1.37, 5.44)] compared with the comparison group.

Conclusion

Parenting interventions including nutrition education and unconditional cash, aimed at improving children’s development, resulted in a reduction in maternal depressive symptoms and improvement in quality of life.
