Progress in the development of a nutritional risk index. Academic Article uri icon

abstract

  • The development of a 16-item nutritional risk index (NRI) is chronicled from its inception through its application in three studies designed to assess its reliability and validity. Study I involved a survey of 401 community-dwelling elderly in St. Louis, Missouri who were interviewed at baseline, 4-5 mo later, and 1 yr later. Study II involved a cross-sectional survey of 377 male outpatients attending two clinics at the St. Louis Veterans Administration Medical Center. Study III involved a cross-sectional survey of 424 community-dwelling elderly in Houston, Texas. Internal consistency reliability coefficients ranged between 0.47 and 0.60, and test-retest reliability coefficients ranged between 0.65 and 0.71. Validity was established by using the NRI to predict the use of health services, as well as by correlating it with a variety of anthropometric, laboratory, and clinical markers of nutritional status. The utility of the NRI for future applications is discussed.
