EVALUATING NUTRITIONAL SURVEY, BIOSTATISTICAL PERSPECTIVE

Abstract

This review evaluates the methodologies of the National Diet and Nutrition Survey (NDNS) and the National Health and Nutrition Examination Survey (NHANES), which are instrumental in assessing the population’s health and nutritional status. It is necessary to create additional biochemical techniques that will offer more precise knowledge about the role of nutrients at the cellular level. It scrutinizes the 24-hour dietary recall’s efficacy in reflecting habitual intake and explores biostatistical techniques for addressing within-individual variance. The article discusses the challenges of dietary assessment, including bias and the need for methodological adaptation. It concludes with the importance of national dietary surveys in informing public health policy and the potential for integrating innovative survey methods.
