Objective To investigate the relationship between unsafe child feces disposal, environmental enteropathy, and impaired growth, we conducted a prospective cohort study of 216 young children in rural ...Bangladesh. Study design Using a prospective cohort study design in rural Bangladesh, unsafe child feces disposal, using the Joint Monitoring Program definition, was assessed using 5-hour structured observation by trained study personnel as well as caregiver reports. Anthropometric measurements were collected at baseline and at a 9-month follow-up. Stool was analyzed for fecal markers of environmental enteropathy: alpha-1-antitrypsin, myeloperoxidase, neopterin (combined to form an environmental enteropathy disease activity score), and calprotectin. Findings Among 216 households with young children, 84% had an unsafe child feces disposal event during structured observation and 75% had caregiver reported events. There was no significant difference in observed unsafe child feces disposal events for households with or without an improved sanitation option (82% vs 85%, P = .72) or by child's age ( P = .96). Children in households where caregivers reported unsafe child feces disposal had significantly higher environmental enteropathy scores (0.82-point difference, 95% CI 0.11-1.53), and significantly greater odds of being wasted (weight-for-height z score <−2 SDs) (9% vs 0%, P = .024). In addition, children in households with observed unsafe feces disposal had significantly reduced change in weight-for-age z-score (−0.34 95% CI −0.68, −0.01 and weight-for-height z score (−0.52 95% CI −0.98, −0.06). Conclusion Unsafe child feces disposal was significantly associated with environmental enteropathy and impaired growth in a pediatric population in rural Bangladesh. Interventions are needed to reduce this high-risk behavior to protect the health of susceptible pediatric populations.
Objective To determine the relationship between geophagy (mouthing of dirt, sand, clay, or mud) and growth faltering in young children. Study design We examined linear growth as height and weight ...standardized by age and sex, and weight standardized by height, in a cohort of children aged 6-36 months in rural Mirzapur, Bangladesh. We determined geophagy behavior at baseline through caregiver report. Anthropometric measurements were assessed at baseline and at a 1-year follow-up. Results We found that among children not stunted at baseline, those with caregiver-reported geophagy at baseline grew less over 1 year compared with their peers, with a difference in the change of standardized height for age and sex of −0.31 (95% CI, −0.61 to −0.01). Conclusion These findings show that caregiver-reported geophagy was associated with growth faltering in a pediatric population in rural Bangladesh. Future studies are needed to learn more about this exposure pathway and its relevance to child growth.
