Season of Data Collection of Child Dietary Diversity Indicators may Affect Conclusions about Longer Term Trends in Peru, Senegal and Nepal

Publication Type



The WHO-UNICEF minimum dietary diversity (MDD) indicator for children aged 6–23 months is a global monitoring indicator used to track multi-year population-level changes in dietary quality, but the influence of seasonality on MDD estimates remains unclear.


Examine how seasonality of data collection may influence population-level MDD estimates and inferences about MDD change over multiple survey years.
