Breastfeeding and complementary feeding
In the Swedish population, breastfeeding rates at 3 mo and 6 mo were 92% and 80% compared with 95% and 88% in the Norwegian part of the study population, respectively. At 12 mo, 22% breastfed their children in Sweden and 51% in Norway.In the NFI group, the mean age of complementary food introduction was 18.3 wk (CI: 18.1, 18.5 wk), whereas infants randomly assigned to food intervention were introduced complementary foods from 12 wk of age. Porridge was the most common first food, other than the interventional foods (peanut, cow milk, wheat, and egg). In the total study population, porridge was introduced in 9.6 % of infants by 3 mo of age, 45.7% at 4 mo, and 25.6% at 5 mo. By 6 mo of age, 81.1% infants had been given porridge. The most frequent porridges to be introduced before 6 mo were oat (62.2%), wheat (40.5%), and corn (34.1%). The following porridge types were given less frequently: millet (18.3%), whole meal (13.3%), spelt (4.1%), Sinlac (4.2%), and other types (5.1%).The cumulative proportion of infants introduced to other complementary foods is listed in Proportion of infants who received various complementary foods at 6, 9, and 12 mo in the No Food Intervention and Food Intervention groupsAbbreviations: FI, Food Intervention; NFI, No Food Intervention.Numbers are presented in %.> Home cooked refers to the infant diet consisting of more home-cooked foods than commercially prepared infant foods, and vice versa for > Commercially prepared.Indicates a significance At 6 mo, 45% of infants were reported to consume mostly or only commercially prepared infant foods, whereas 9% consumed only home-cooked foods.
