Community-based asthma assessment in young children: adaptations for a multicentre longitudinal study in South Asia.

Background: Systematic assessment of childhood asthma is challenging in low- and middle-income country (LMIC) settings due to the lack of standardised and validated methodologies. We describe the contextual challenges and adaptation strategies in the implementation of a community-based asthma assessment in four resource-constrained settings in Bangladesh, India, and Pakistan.

Method: We followed a group of children of age 6-8 years for 12 months to record their respiratory health outcomes.
