NUTRITION, OVERNUTRITION, AND OBESITY IN THE FIRST YEAR OF LIFE IN MALMÖ, SWEDEN

Abstract

The feeding pattern, calorie intake, weight and height were studied at various ages during the first 12 months in 243 infants born in Sweden. The feeding pattern and calorie intake was close to that recommended. 0-6% in each age group were found to be obese (20-40% above the standard weight) and 15-23% overweight (10-20% above the standard weight). The mean calorie intake during the months before and when obesity and overweight were diagnosed exceeded the normal by 10% or less. When re-examined at age 2 plus or minus 1/2 years, 50% of those children obese up to 1 year remained so, and only 2 earlier overweight had become obese. 25% of the obese children had one obese parent, compared with 10% of the normal children and overweight ones. The low incidence of overnutrition and the low freqency of obese and overweight infants in this study compared with previous studies support the idea that high calorie intake is of importance in the development of obesity during infancy. Accordingly, overnutrition seems to be one factor, in the multifactorial aetiology of obesity, and reduction of overnutrition can reduce, but not abolish, infantile obesity. Whether the reduction of this will subsequently prevent adult obesity remains to be proved.
