Description

De Jong et al developed a nutritional index based on clinical and laboratory data to evaluate an adult patient for malnutrition. The authors are from the University of Limburg in Maastricht, The Netherlands.


Parameters:

(1) serum albumin in g/L

(2) serum prealbumin in g/L

(3) total lymphocyte count in 10^9/L

(4) percent of ideal weight

 

nutritional index (NI) =

= (-0.24 * (serum albumin)) – (19.21 * (serum prealbumin)) – (1.86 * (total lymphocyte count)) – (0.04 * (percent ideal weight)) + 20.68

 

where:

• The percent ideal weight = (actual body weight) / (ideal body weight) * 100

• The ideal body weight is based on the Metropolitan Life Insurance Company tables.

 

Interpretation:

• An index > 0 indicates that the patient is malnourished.

• An index <= 0 indicated that the patient is not malnourished.
