  • Course Learning Objectives

    Upon successfully completing this course, students will be able to:

    • apply a conceptual framework for choosing appropriate indicators of nutritional status for different research and programmatic applications
    • identify key methodological issues when assessing dietary intake, biochemical and anthropometric indicators, and the implications of those issues for assessing nutrition disease relationships
    • apply statistical methods for evaluating indicators of nutritional status, for choosing among candidate indicators and for assesing biases in nutrition-disease relationships
  • Course Description
    Reviews methodological issues related to nutritional assessment in the context of clinical, epidemiological, and programmatic research design. Discusses nutrition surveillance, cohort studies, field intervention trials, assessment techniques, and research design, including data collection, analysis, and interpretation.
  • Intended Audience

    Additional Faculty Notes:
    All individuals interested in methodological issues related to nutrition data.

  • Methods of Assessment
    Student evaluation based on class participation and homework exercises.

    Additional Faculty Notes:

    Student performance will be evaluated by class participation (10%) and six homework exercises (90%). The homework assignments are weighted according to the number of points assigned.

  • Course Objectives(from old syllabus)
    1. Provide a conceptual framework relating nutrition, nutriture, and nutritional status, and thus a framework for examining dietary intakes and indicators of nutritional status as they relate to disease risk in epidemiological research 2. Familiarize students with concepts such sensitivity, specificity, positive and negative predictive values, ROC curves, and normalized distance measures as they are applied to nutrition epidemiology 3. Provide practice in using statistical criteria for comparing performance of indicators of nutritional status for various applications 4. Give experience in assessing the levels and sources of measurement error inherent in nutritional assessment 5. Understand the implications of measurement error on study design and execution, prevalence estimates and measures of association 6. Develop an understanding of the complexity of analyzing and interpreting nutritional data and the biological and statistical issues related to energy adjustment 7. Provide experience in interpreting nutritional data
