Objective To compare the effect of unmodified cows'milk and iron supplemented formula milk on psychomotor development in infants from inner city areas when used as the main milk source.
Design Double blind, randomised intervention trial.
Subjects 100 infants, mean age 7.8 months (range 5.7 to 8.6 months), whose mothers had already elected to use unmodified cows'milk as their infant's milk source.
Intervention Changing to an iron supplemented formula milk from enrolment to 18 months of age, or continuing with unmodified cows'milk.
Main outcome measures Developmental assessments using Griffiths scales at enrolment and at 18 and 24 months.
There were no significant differences in haemoglobin concentration between the two groups at enrolment, but by 18 months of age 33% of the unmodified cows'milk group, but only 2% of the iron supplemented group, were anaemic (P<0.001).
The experimental groups had Griffiths general quotient scores that were not significantly different at enrolment, but the scores in both groups declined during the study.
By 24 months the decrease in the mean scores in the unmodified cows'milk group was 14.7 whereas the decrease in the mean scores in the iron supplemented group was 9.3 (P<0.02,95% confidence interval 0.4 to 10.4).
Mean subquotient scores were considerably lower in the unmodified cows'milk group at 24 months ; significantly so for personal and social scores (P<0. (...)
