Clinical validation of a nutritional risk index

This research assessed the clinical validity of a nutritional risk index (NRI). Subjects were 377 male veterans, aged 55+, attending general medicine and geriatric outpatient clinics. Data were collected by personal interviews, anthropometric measurements, laboratory assay of nutritional parameters, three-day food records, and medical record reviews. Although the results showed that the NRI correlated significantly with only two nutritional measures (body mass index, total energy intake), critical values or threshold levels of NRI were identified that significantly discriminated low risk from high risk patients on four nutritional parameters (body mass index, total energy intake, laboratory risk, and medications risk). It was concluded that the NRI is a valid measure of health status and contains a nutritional dimension.John M.
