INDIVIDUAL PATTERNS OF FOOD-INTAKE DEVELOPMENT IN CHILDREN - A 10 MONTHS TO 8 YEARS OF AGE FOLLOW-UP-STUDY OF NUTRITION AND GROWTH

Individual patterns of food intake development have been investigated on the basis of a longitudinal study of nutrition and growth carried o ut in 112 children at the ages of 10 months, and 2, 4, 6, and 8 years. On the average, energy intake increased steadily with age. However, i ndividual subjects sometimes followed a different pattern. Approximatl y 1 out of 5 subjects decreased their intake between two examinations. Besides, less than half the children (43%) were in the same category of energy intake (defined as tertiles) at 10 months and 8 years of age . Similarly, 47% of the children were in the same weight/height(2) (BM I) category at 10 months and 8 years. Correlations computed between ea rly intakes (10 months, and 2, 4, and 6 years) and intakes at 8 years were better for energy and protein intake than for fat and carbohydrat es (CHO), showing that intake of energy or protein early in life has a better predictive value of intake at later ages. Energy intake develo pment has been examined in those children who were found to be lean, m edium, and fat at the age of 8 years; it increased more between the ag es of 4 and 6 years, in children who were fat at 8 years. Individual v ariations of anthropometric measurements during growth are well docume nted. The present study points out that similar individual variations of intake also exists. These variations could reflect regulatory proce sses acting during growth and should be taken into account in investig ating the child's appetite.
