Z-scores is uses in the analysis of human nutritional data, especially for children. Weight for age, height for age, and weight for height Z-scores are computed using international reference data intended to reflect human growth patterns under optimal conditions. Cut-off scores of -2 and -3 are used to identify children suffering from malnutrition. Mean Z-scores are used to evaluate the nutritional state of populations relative to the reference population.
