Primary follow-up care in a multidisciplinary setting enhances catch-up growth of very-low-birth-weight infants.

OBJECTIVE

To determine the impact of multidisciplinary primary care follow-up, which included the services of a registered dietitian, on growth outcomes of very-low-birth-weight (VLBW) infants.

DESIGN

Data were obtained retrospectively from medical records. Forty-two infants receiving follow-up care on an as needed basis from the general pediatric clinic were compared with 33 infants receiving multidisciplinary follow-up care that included routine nutrition intervention from the comprehensive care clinic. Comparisons were made in weight, length, and head circumference measurements; growth rates; and catch-up growth (defined as > or = 5th percentile on growth charts of the National Center for Health Statistics attained by 12 months growth-corrected age).

SUBJECTS

VLBW infants (< or = 1,500 g at birth) were selected from both follow-up groups.

STATISTICAL ANALYSIS

Chi 2 Analysis compared the proportions of infants in each group who achieved catch-up growth. Unpaired t tests compared group means in weight, length, and head circumference measurements and growth rates.

RESULTS

The two groups differed significantly in the number of infants exhibiting catch-up growth for length and head circumference. At 8 months growth-corrected age, 7 (28%) of the general pediatric clinic infants were at the 5th percentile or greater for length compared with 21 (64%) of the comprehensive care clinic infants (P < .01); 15 (60%) of the general pediatric clinic group and 30 (91%) of the comprehensive care clinic group were at the 5th percentile or greater for head circumference (P < .05). At 12 months growth-corrected age, 12 (57%) of the general pediatric clinic infants and 26 (87%) of the comprehensive care clinic infants were at the 5th percentile or greater for length (P < .05); 11 (52%) of the general pediatric clinic infants and 27 (90%) of the comprehensive care clinic infants were at the 5th percentile or greater for head circumference (P < .05).

APPLICATIONS

Multidisciplinary primary care follow-up that includes the services of a registered dietitian for nutrition intervention can enhance the catch-up growth of VLBW infants through 12 months growth-corrected age.
