Objective |
To evaluate the relationship between mouthing of soil and living in unsanitary conditions and child cognitive development in urban Bangladesh.
Study design |
This prospective cohort study of 224 children under 5 years of age was conducted in urban Dhaka, Bangladesh. Developmental outcomes were assessed by communication, fine motor, gross motor, personal social, problem solving, and combined developmental scores measured by the Extended Ages and Stages Questionnaire (EASQ) at a 12-month follow-up visit.
Results |
Children who had caregiver reports of putting soil in their mouths at the majority of surveillance visits had significantly lower combined EASQ Z scores (coefficient, −0.53; 95% CI, −0.83 to −0.22) at the 12-month follow-up visit. Children who had caregiver reports of putting visibly dirty objects in their mouths at the majority of visits had significantly lower combined EASQ Z scores (−0.50; 95% CI, −0.79 to −0.22). Children in households with unimproved sanitation had significantly lower combined EASQ Z scores (−0.63; 95% CI, −1.11 to −0.16).
Conclusions |
Children found to frequently put soil and visibly dirty objects in their mouths, and those who resided in households using unimproved sanitation, had lower subsequent cognitive developmental outcomes. These findings demonstrate the importance of interventions targeting child mouthing behaviors and sanitation infrastructure to decrease exposure to fecal pathogens and improve child cognitive developmental outcomes.
