Validation of a digitally displayed photographic food portion-size estimation aid among women in urban and rural Malawi.

Objective

To validate digitally displayed photographic portion-size estimation aids (PSEA) against a weighed meal record and compare findings with an atlas of printed photographic PSEA and actual prepared-food PSEA in a low-income country.
