Socio-demographic, maternal, and infant characteristics associated with early childhood development delays among children of young mothers in Brasília, Brazil

Abstract

Background

Holistic attention to adolescent health is needed to sustain the benefits of investment in early childhood development. Any such interventions must make sure to address the needs of adolescent and young adult parents. This study explored the social and demographic maternal variables associated with risk of early childhood development (ECD) delay for children of young mothers in Brazil.

Methods

Cross-sectional secondary data analysis was done using data from young mothers (aged 13–24) and their children (aged 0–2), collected from community health centers in Brasília, Brazil, between 2017–2018. The Denver Developmental Screening Test II was used to assess risk of ECD delay outcomes. Descriptive analyses were conducted across the full sample and sub-groups of adolescent (13–19) and young adult (20–24) mothers. Multivariable logistic regressions based on theory modelling approach were conducted for the full sample to examine the associations between maternal age and risk of ECD delay, adjusted for a battery of household, maternal, pregnancy, and infant variables.

Results

Risk of ECD delay was found in 17.39% (N = 76) of the children who participated (N = 437). No significant differences in risk of ECD delay were found for children of adolescent mothers compared to children of young adult mothers. Across the full sample, 60.36% (N = 236) of mothers were living in poverty, 73.17% (N = 319) had 9 or more years of education, and 86.14% (N = 373) were not working outside the home at time of data collection. Furthermore, 90.11% (N = 392) did not identify as head of their household and 73.68% (N = 322) were primiparous. Socially-mediated factors such as lower maternal educational attainment, unemployment, and lack of household support were associated with increased risk of ECD delays for children under age 2. Adjusted logistic regression identified multiparity as an independent maternal factor associated with increased risk of ECD delay (AOR = 2.51; 95% CI, 1.23–5.13).

Conclusions

Multiparity was the only independent maternal factor associated with ECD delay among children under 2 years old. Other socio-demographic factors relevant to young mothers may influence ECD delays. Ensuring sustained, concurrent attention to children’s and young parent’s developmental needs may improve multi-generational health outcomes.
