Insights
Childhood stunting, wasting, and underweight are linked to cognitive and motor skill deficits. However, impaired growth in infants was not associated with geophagy (eating soil).
Area of Science:
- Child Nutrition and Development
- Pediatric Health Outcomes
- Global Child Health
Background:
- Anthropometric characteristics are crucial indicators of child health.
- Geophagy, the consumption of earth or soil-like substances, is a practice observed in some populations.
- Cognitive and motor development are foundational for a child's overall well-being.
Purpose of the Study:
- To investigate the relationship between children's anthropometric status and their cognitive function.
- To explore the association between anthropometric characteristics and geophagy in infants.
- To determine the impact of geophagy on cognitive and motor development.
Main Methods:
- Prospective cohort study of 632 singleton infants from birth to 12 months in Benin.
- Anthropometric measurements (stunting, wasting, underweight) assessed at birth, 9, and 12 months.
- Cognitive and motor functions evaluated using Mullen Scales of Early Learning; geophagy reported by parents.
Main Results:
- Prevalence of stunting, wasting, and underweight ranged from 12.7% to 17.7% at 9 and 12 months.
- Geophagy was reported in 48.2% of children at 12 months.
- Impaired growth (stunting, wasting, underweight) was significantly associated with lower cognitive and gross motor scores.
Conclusions:
- Childhood stunting, wasting, and underweight are associated with cognitive and gross motor deficits.
- Impaired growth in this cohort was not linked to geophagy.
- Further prospective research on geophagy and growth from birth to 36 months is recommended.
Objectives:
The aim of this study was to investigate the relationship between anthropometric characteristics and both geophagy and cognitive function of children.
Study Design:
The study prospectively followed singleton children whose mothers participated in the MiPPAD clinical trial in Allada, Benin, from birth to age 12 months. Anthropometric measurements were taken at birth and 9 and 12 months. Wasting, stunting and underweight were defined as weight-for-length, length-for-age and weight-for-age Z-scores less than -2, respectively. Cognitive and motor functions were assessed using the Mullen Scales of Early Learning. Parent-reported geophageous habits of children were collected when the children were 12 months. Multiple linear and logistic regressions were used to analyse the data.
Results:
A total of 632 children (49.7% girls) were involved in the study. Stunting, wasting and underweight were observed in 14.1%, 13.6% and 17.7%, respectively, at 9 months and 17.3%, 12.7% and 17.2%, respectively, at 12 months. The prevalence of geophagy among the children was 48.2%. Impaired growth at 9 and 12 months was consistently associated with low cognitive and gross motor (GM) score. Children stunted at 9 months had lower GM scores at 12 months compared with their non-stunted peers (β = -3.48, 95% confidence interval -6.62 to -0.35).
Conclusions:
Stunting, wasting and underweight are associated with cognitive and GM deficits in infants. In this setting, impaired growth was not associated with geophagy. Further research evaluating geophagy and growth prospectively and concurrently from birth to 36 months is needed.
