    • In this activity, you will develop a plan for a nutrition survey that you could potentially implement in your country. 

      Step 1: Review 

      Review the steps in conducting a nutrition survey by reviewing pages 11-17 of this document: Guidelines for Nutrition Surveys

      Step 2: Design and Develop

      Using the steps provided by the learning resource, develop a plan for a nutrition survey that you could potentially implement in your country. Keep in mind that the steps are the most important, as they help you determine the purpose of your survey and the important nutrition issues that you are trying to address from the survey.

      Step 3: Respond

      Respond by drafting a 2-page brief plan with the following inclusions:

      • A survey plan that addresses all the steps outlined in the resource document
      • Purpose of the survey and the nutrition-related diseases (such as micronutrient deficiencies or chronic diseases) you want to address

      Step 4: Share
