- OBJECTIVE: Low birth weight (LBW) infants are at increased risk of cognitive and behavioral problems and at risk for iron deficiency, which is associated with impaired neurodevelopment. We hypothesized that iron supplementation of LBW infants would improve cognitive scores and reduce behavioral problems. METHODS: In a randomized controlled trial, 285 marginally LBW (2000-2500 g) infants received 0, 1, or 2 mg/kg/day of iron supplements from 6 weeks to 6 months of age. At 3.5 years of age, these infants and 95 normal birth weight controls were assessed with a psychometric test (Wechsler Preschool and Primary Scale of Intelligence) and a questionnaire of behavioral problems (Child Behavior Checklist; CBCL). RESULTS: There were no significant differences in IQ between the LBW groups or LBW infants versus controls. Mean (SD) full-scale IQ was 105.2 (14.5), 104.2 (14.7), and 104.5 (12.7) in the placebo, 1 mg, and 2 mg groups, respectively (P = .924). However, for behavioral problems, there was a significant effect of intervention. The prevalence of children with CBCL scores above the US subclinical cutoff was 12.7%, 2.9%, and 2.7% in the placebo, 1-mg, and 2-mg groups, respectively (P = .027), compared with 3.2% in controls. Relative risk (95% confidence interval) for CBCL score above cutoff in placebo-treated children versus supplemented was 4.5 (1.4-14.2). CONCLUSIONS: Early iron supplementation of marginally LBW infants does not affect cognitive functions at 3.5 years of age but significantly reduces the prevalence of behavioral problems. The study suggests a causal relation between infant iron deficiency and later behavioral problems.

- Background: Celiac disease is defined as a 'chronic small intestinal immune-mediated enteropathy precipitated by exposure to dietary gluten in genetically predisposed individuals'. Sweden has experienced an "epidemic" of celiac disease in children below two years of age. Celiac disease etiology is considered multifactorial; however, little is known regarding potential risk-or protecting factors. We present data on the possible association between early infectious episodes and celiac disease, including their possible contribution to the Swedish celiac disease epidemic. Methods: A population-based incident case-referent study (475 cases, 950 referents) with exposure information obtained via a questionnaire (including family characteristics, infant feeding, and the child's general health) was performed. Celiac disease cases were diagnosed before two years of age, fulfilling the diagnostic criteria of the European Society for Pediatric Gastroenterology, Hepatology and Nutrition. Referents were randomly selected from the national population register after fulfilling matching criteria. The final analyses included 954 children, 373 (79%) cases and 581 (61%) referents, with complete information on main variables of interest in a matched set of one case with one or two referents. Results: Having three or more parental-reported infectious episodes, regardless of type of infection, during the first six months of life was associated with a significantly increased risk for later celiac disease, and this remained after adjusting for infant feeding and socioeconomic status (odds ratio [OR] 1.5; 95% confidence interval [CI], 1.1-2.0; P=0.014). The celiac disease risk increased synergistically if, in addition to having several infectious episodes, infants were introduced to dietary gluten in large amounts, compared to small or medium amounts, after breastfeeding was discontinued (OR 5.6; 95% CI, 3.1-10; P<0.001). Conclusion: This study suggests that having repeated infectious episodes early in life increases the risk for later celiac disease. In addition, we found a synergistic effect between early infections and daily amount of gluten intake, more pronounced among infants for whom breastfeeding had been discontinued prior to gluten introduction. Regarding contribution to the Swedish celiac disease epidemic, which partly was attributed to concurrent changes in infant feeding, early infections probably made a minor contribution via the synergistic effect with gluten amount.

- To decrease BMI in overweight and obese children, improved dietary intake and increased physical activity are key elements. Our objective was to evaluate the impact of a 1-y food and physical activity intervention on energy and macronutrient intake in overweight and obese children. A randomized open trial was conducted with 92 overweight or obese 10.4 ± 1.08-y-old children. The intervention included 14 group sessions with different themes regarding food and physical activity. Dietary intake was assessed with diet history interviews covering 14 d at baseline and 4-d food records after 1 y and was evaluated according to national dietary recommendations. The control group participated in the same measurements as the intervention group but did not take part in group sessions. After 1 y, both groups had decreased their energy intake (EI) relative to total energy expenditure, but the effect was more pronounced for the intervention group than for the control group. At 1 y follow-up, a larger proportion of children in the intervention group compared with the control group met the recommended intake of refined sugar (P = 0.019). However, the groups did not differ in the proportion children who met the recommended intake of dietary fiber. Further, SFA intake relative to total EI did not differ between the groups at 1 y follow-up. In conclusion, despite a rather comprehensive intervention, only modest effects were achieved with respect to reduced EI and improved macronutrient intake.

- In rodents, bile salt-stimulated lipase (BSSL) and pancreatic lipase-related protein 2 (PLRP2) are the dominant lipases expressed in the exocrine pancreas in early life, when milk is the main food. The aim of the present study was to evaluate if BSSL and PLRP2 are also key enzymes in neonatal intestinal fat digestion. Using Caco-2 cells as a model for the small intestinal epithelium, purified human enzymes were incubated in the apical chamber with substrates and bile salt concentrations resembling the milieu of the small intestine of newborn infants. BSSL and PLRP2 hydrolyzed triglycerides (TG) to free fatty acids (FA) and glycerol. The cells took up the FA, which were reesterfied to TG. Together, BSSL and PLRP2 have a synergistic effect, increasing cellular uptake 4-fold compared to the sum of each lipase alone. A synergistic effect was also observed with retinyl ester as a substrate. PLRP2 hydrolyzed cholesteryl ester but not as efficiently as BSSL, and the two had an additive rather than synergistic effect. We conclude the key enzymes in intestinal fat digestion are different in newborns than later in life. Further studies are needed to fully understand this difference and its implication for designing optimal neonatal nutrition.

- Objectives: Preterm infants often experience suboptimal growth, which can affect organ development. The aim of this study was to improve growth by treatment with bile salt-stimulated lipase (BSSL), naturally present in breast milk, but lost after pasteurization, and absent in formula. Methods: Two clinical trials were performed with a predefined analysis of combined data to investigate the effects of recombinant human BSSL (rhBSSL) treatment on growth velocity and fat absorption in preterm infants. The studies were randomized and double-blinded comparing 7-day treatment with rhBSSL and placebo, administered in pasteurized breast milk or formula, using a crossover design. Results: Sixty-three infants were evaluated for safety. At randomization, the mean (standard deviation) weight was 1467 (193) g and mean postmenstrual age was 32.6 (0.5) weeks. Sixty and 46 infants were evaluated for growth velocity and fat absorption, respectively. rhBSSL treatment significantly improved mean growth velocity by 2.93 g.kg(-1).day(-1) (P<0.001) compared with placebo (mean 16.86 vs 13.93 g.kg(-1).day(-1)) and significantly decreased the risk of suboptimal growth (<15 g.kg(-1).day(-1)) (30% vs 52%, P = 0.004). rhBSSL significantly increased absorption of the long-chain polyunsaturated fatty acids, docosahexaenoic acid, and arachidonic acid by 5.76% (P = 0.013) and 8.55% (P = 0.001), respectively, but had no significant effect on total fat absorption. The adverse-event profile was similar to placebo. Conclusions: In preterm infants fed pasteurized breast milk or formula, 1 week of treatment with rhBSSL was well tolerated and significantly improved growth and long-chain polyunsaturated fatty acid absorption compared to placebo. This publication presents the first data regarding the use of rhBSSL in preterms and the results have led to further clinical studies.

Tidskriftsartikel (refereegranskat)abstract
- Iron requirements in late infancy are higher than during any other period in life. Iron deficiency is the most common nutritional deficiency in children worldwide. It is estimated that close to 50% of preschool children are anemic globally, and most of these children are anemic due to iron deficiency. Much new information has been published in the last decade on requirements, metabolism, physiological and neurodevelopmental effects of iron as well as of iron deficiency. The challenges to define strategies for prevention, treatment by managing the risk of adverse effects of too much iron given to iron-replete individuals remain. This issue of the Annales is therefore dedicated to the topic "Iron Deficiency in Infancy and Childhood".

- Objectives:To evaluate possible associations between body mass index (BMI) at 4 years of age, current and previous dietary intakes and parental BMI.Methods:A follow-up of dietary intake and anthropometry in 127 4-year-old children corresponding to 54% of children who completed an initial intervention study at 18 months of age.Results:Fourteen percent of the girls and 13% of the boys were overweight (age-adjusted BMI>/=25) and 2% of the girls and 3% of the boys were obese (age-adjusted BMI>/=30). Thirty-four percent and 9% of the fathers and 19 and 7% of the mothers were overweight and obese, respectively. BMI at 6-18 months was a strong predictor of BMI at 4 years. Univariate regression analyses revealed that intake of protein in particular, and also of total energy and carbohydrates at 17/18 months and at 4 years, was positively associated with BMI at 4 years. Although BMI at 6-18 months was the strongest predictor of BMI at 4 years, in the final multivariate models of the child's BMI, protein intake at 17-18 months and at 4 years, energy intake at 4 years and the father's-but not the mother's-BMI were also independent contributing factors.Conclusions:Among these healthy children, BMI at 4 years of age tracked from 6 to 18 months of age and were associated with previous and current protein intake as well as parental BMI, particularly that of the father.
