The IIT Bombay nutrition group has been engaged in research for generating policy inputs for maternal and child health and malnutrition. This involves use of large data sets such as NFHS and HMIS. Analysis of this secondary data, including geo-spatial analysis has helped the group to publish useful research and also prepare useful policy briefs. The work largely involves bringing out regional patterns for different indicators of child malnutrition and maternal and child health such as undernutrition among children, birth seasonality, patterns of still births and preterm births and their correlates. On the conceptual side, the issue of a suitable composite index, the problem of urban restructuring of programme interventions and a multi-layer perspective on child malnutrition are also involved.
