Can community health workers mitigate environmental health risks to improve maternal and child health outcomes?
Low rates of exclusive breastfeeding and exposure to water-borne contaminants due to inadequate sanitation, water treatment, and hygiene contribute to high levels of infant morbidity and mortality in low-income countries. This pilot leverages detailed micro-data from over 100,000 households in Punjab, Pakistan in combination with a quasi-experimental change in Community Health Worker (CHW) coverage to generate high-quality evidence on the impact of CHW-based community health work and its interaction with a key environmental health threat: poor water quality due to inadequate sanitation.
