  • Course Description
    The course will provide an introduction to the methodological issues involved in the design, conduct, analysis and interpretation of studies investigating the relationship between nutritional status, diet and disease. Emphasis will be placed on issues such as intraindividual variation, measurement of error, misclassification, correlated variables, population homogeneity, and the use of group versus individual data. The selection and use of dietary and nutritional status assessment methods appropriate for different study designs will be covered, and some experience in their use and interpretation will be provided. The impact of methodological issues, and of the type of study design, on interpretation and conclusions from research in nutrition epidemiology will be emphasized. Prerequisites: None.
  • Intended Audience

  • Welcome Message

    This course is designed to review methodological issues related to nutritional assessment in the context of clinical, epidemiological, and programmatic research design. Discussions will be held on topics such as nutrition surveillance, cohort studies, field intervention trials, assessment techniques, and research design, including data collection, analysis, and interpretation.

  • Course topics

    1. Nutriture, nutrition and nutritional status: a conceptual framework for understanding nutrition research 2. Statistical methods for assesssing indicator performance 3. Measurement issues: technique, validity, and reliability 4. Implications of measurement error 5. Selected issues in analysis and interpretation of nutrition data

  • 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
