CALORIE REQUIREMENTS FOR WEIGHT GAIN IN INFANTS WITH GROWTH FAILURE DUE TO MATERNAL DEPRIVATION, UNDERNUTRITION, AND CONGENITAL HEART DISEASE

A Correlation Analysis

Ingeborg Krieger M.D.1 and You C. Chen M.D.1

The correlation between calorie intake and weight gain was analyzed in 31 patients with growth failure who were 5 to 36 months old. The BMR and that portion of the total daily calorie intake which is responsible for weight gain ("residual calories") was calculated, using a fixed estimate for muscular activity and calorie losses. The BMR per weight predicted from height was similar to normal controls. The correlations between residual calories and gram weight gain, and between total calories per predicted weight and weight gain per predicted weight were good (p < .01). Total calories per gram weight gain followed a log-log regression on weight gain (gram/day/kilogram predicted weight) when normal standard values were used (r = .999). This relationship was examined in the patients with growth failure (r = .971). The slopes and height of the slopes were similar.

It is concluded that calorie requirements were predictable, because the BMR and the calorie cost of weight gain were predictable. Calorie losses and muscular activity apparently did not vary significantly in this patient sample. Calorie requirements were roughly comparable to those of normal infants when predicted weight was used as reference standard, because the BMR predicted weight was normal and other expenditures apparently did not differ significantly from those to be expected of well children of the same age.
