Background/Objectives: To assess the validity of a 7-day pre-coded food record (PFR) method in 9-month-old infants against metabolizable energy intake (ME DLW ) measured by doubly labeled water (DLW); additionally to compare PFR with a 7-day weighed food record (WFR) in 9-month-old infants and 36-month-old children. Subjects/Methods: The study population consisted of 36 infants (age: 9.03±0.2 months) and 36 young children (age: 36.1 ± 0.3 months) enrolled in a cross-over design of 7 consecutive days PFR vs 7 consecutive days WFR. Children were randomly assigned to one method during week 1, crossing over to the alternative method in week 2. Total energy expenditure (TEE) and ME DLW were obtained in the 9-month-old infants using the DLW technique for 7 days while recording with PFR. Results: For the 9-month-old group, PFR showed a mean bias of þ 726 kJ/day, equivalent to 24%, (Po0.0001) compared with ME DLW (n ¼ 29). Using WFR as the reference in this group no between-method differences were found for energy, fat and carbohydrate. Energy intake in the 36-month-old children was 12% higher in the PFR vs WFR (Po0.0001), and protein plus total fat intake were overestimated with the PFR (P ¼ 0.008, Po0.0001, respectively). Conclusions: The study indicates that the PFR may be a valuable tool for measuring energy, energy-yielding nutrients and foods in groups of 9-month-olds infants and 36-month-olds young children.
Coeliac disease (CD) affects about 1 % of the general population. Information concerning gluten intake in the general population is scarce. In particular, variation in gluten intake during the complementary feeding period may be an independent risk factor in CD pathogenesis. We determined the intake of gluten from wheat, barley, rye and oats in a cross-sectional National Danish Survey of Dietary Habits among Infants and Young Children (2006–2007). The study population comprised a random sample of 1743 children aged 6–36 months, recruited from the National Danish Civil Registry. The protein contents from wheat, rye, barley and oats were found in the National Danish Food Composition Table, and multiplied with the amounts in the recipes. The amounts of gluten were calculated as the amount of cereal protein × 0·80 for wheat and oats, ×0·65 for rye and ×0·50 for barley. Dietary intake was recorded daily for seven consecutive days in pre-coded food records supplemented with open-answer possibilities. Gluten intake increased with age (P < 0·0001). Oats were introduced first, rapidly outpaced by wheat, the intake of which continued to increase with age, whereas oats started to decrease at 12 months. Boys had a higher intake of energy (P ≤ 0·0001) and all types of gluten, except for barley (P ≤ 0·87). In 8–10-month-old (P < 0·0001) and 10–12-month-old (P = 0·007), but not in 6–8-month-old infants (P = 0·331), non-breast-fed infants had higher total gluten intake than partially breast-fed infants. In conclusion, this study presents representative population-based data on gluten intake in Danish infants and young children.
Objective: To test whether there are differences in diet diversity between children still being partly breast-fed at 9 months and those completely weaned at the same age. Design: Cross-sectional study. Setting: Cross-sectional study (SKOT cohort) in the area of Copenhagen, Denmark. Subjects: Healthy term infants (n 312) at 9 months of age (mean 9?1 (SD 0?3) months). Results: The infants partly breast-fed (n 168) at 9 months had significantly lower body weight (P , 0?0001), were significantly shorter (P 5 0?0022) and were introduced to complementary foods significantly later (P , 0?0001) than completely weaned infants (n 141) of similar age. Furthermore, they had lower intake of energy, both in absolute amount (P , 0?0001) and per kilogram of body weight (P 5 0?049). Significantly lower intakes of most energy-yielding nutrients, in absolute amounts and as energy percentages, were seen for the partly breast-fed compared with the completely weaned infants. These differences appear to be caused primarily by differences in the type and amount of milk consumed, as the energy derived from sources other than milk was similar except for fatty spread and vegetables as a side dish. Only small differences were found for absolute intakes of foods between feeding groups, although fatty spread had significantly higher intake rates and consumption (P 5 0?031) among partly breast-fed compared with completely weaned infants. Conclusions: At 9 months the infants partly breast-fed did not eat a less diversified diet compared with those completely weaned at the same age. Despite later introduction to complementary foods compared with the completely weaned, their intake of foods was similar and no delay in their progression towards the family foods was noted.
