Adaptation and validation of a dietary diversity questionnaire to predict nutrient adequacy in children aged 24 to 59 months in Iran: national food and nutrition surveillance.

ABSTRACT:

Background

Dietary Diversity Score (DDS), as a proxy for nutritional adequacy, can be used as a useful tool to assess diet quality, especially in children, due to its low cost and ease of use in comprehensive studies. This study aimed to develop a questionnaire to estimate dietary diversity and also assess the validity of DDS as an indicator of nutritional status among children aged 24 to 59 months in Iran.
