- Low birth weight (LBW), defined as a birth weight of < 2,500 g, affects 16% of all newborns and is a risk factor for impaired neurodevelopment as well as adverse cardiovascular and metabolic outcomes, including hypertension. LBW infants include both term, small for gestational age infants and preterm infants. Most LBW infants have only marginally LBW (2,000-2,500 g). Recent advances in neonatal care have significantly improved the survival of very LBW (VLBW) infants (< 1,500 g). LBW infants are at high risk of iron deficiency due to low iron stores at birth and higher iron requirements due to rapid growth. Using a factorial approach, iron requirements of LBW infants have been estimated to be 1-2 mg/kg/day, which is much higher than the requirements of term, normal birth weight infants, who need almost no dietary iron during the first 6 months of life. In VLBW infants, blood losses and blood transfusions related to neonatal intensive care, as well as erythropoietin treatment, will greatly influence iron status and iron requirements. The timing of umbilical cord clamping at birth is of great importance for the amount of blood transfused from the placenta to the newborn and thereby total body iron. Delayed cord clamping of LBW infants is associated with less need for blood transfusion, less intraventricular hemorrhage, and less necrotizing enterocolitis. Randomized controlled trials have shown that an iron intake of 1-3 mg/kg/day (1-2 mg for marginally LBW and 2-3 mg for VLBW) is needed to effectively prevent iron deficiency. There is some recent evidence that these levels of iron intake will prevent some of the negative health consequences associated with LBW, especially behavioral problems and other neurodevelopmental outcomes and possibly even hypertension. However, it is also important to avoid excessive iron intakes which have been associated with adverse effects in LBW infants.

- Background: Type 2 diabetes, chronic kidney disease (CKD) and its cardiovascular complications are increasing as health problems worldwide. These diseases are interrelated with overlapping occurrence and once diabetes is established, the risk of cardiorenal disease is dramatically elevated. Thus, a search for unifying modifiable risk factors is key for effective prevention. Summary: Elevated fasting plasma concentration of vasopressin, measured with the marker copeptin, predicts new onset type 2 diabetes as well as renal function decline. Furthermore, we recently showed that increased plasma copeptin concentration independently predicts the development of both CKD and other specified kidney diseases. In consequence, high copeptin is an independent risk factor for cardiovascular disease and premature mortality in both diabetes patients and in the general population. Vasopressin is released when plasma osmolality is high, and the easiest way to lower plasma vasopressin and copeptin concentration is to increase water intake. In a human water intervention experiment with 1 week of 3 L/day increased water intake, the one third of the participants with the greatest copeptin reduction (water responders) were those with a phenotype of low water intake (high habitual plasma copeptin and urine osmolality, and low urine volume). The water-responders had a copeptin reduction of 41% after 1 week of increased water intake compared to a control week; in contrast, a 3% reduction occurred in the other two thirds of the study participants. Among water responders, increased water intake also induced a reduction in fasting glucagon concentration. Key Messages: Elevated copeptin, a measure of vasopressin, is a risk marker of metabolic and cardiorenal diseases and may assist in the detection of individuals at higher risk for these diseases. Furthermore, individuals with high copeptin and other signs of low water intake may experience beneficial glucometabolic effects of increased water intake. Future randomized control trials investigating effects of hydration on glucometabolic and renal outcomes should focus on individuals with signs of low water intake including high plasma copeptin concentration.

Core Data Necessary for Reporting Clinical Trials on Nutrition in Infancy

- This paper presents an updated and revised summary of the 'core data set' that has been proposed to be recorded and reported in all clinical trials on infant nutrition by the recently formed Consensus Group on Outcome Measures Made in Paediatric Enteral Nutrition Clinical Trials (COMMENT). This core data set was developed based on a previous proposal by the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Committee on Nutrition in 2003. It comprises confidential data to identify subjects and facilitate contact for further follow-up, data to characterize the cohort studied and data on withdrawals from the study, and some additional core data for all nutrition studies on preterm infants. We recommend that all studies on nutrition in infancy should collect and report this core data set to facilitate interpretation and comparison of results from clinical studies, and of systematic data evaluation and meta-analyses. Editors of journals publishing such reports are encouraged to require the reporting of the minimum data set described here either in the main body of the publication or as supplementary online material.

- Introduction: Infrequent fruit and vegetable (FV) intake is especially common among children with low parental educational level (PEL) and among boys.Objectives: Our aim was to examine whether a school-based intervention was efficient in increasing children’s FV intake especially among those whose FV intake is the lowest and which factors could explain the the group differences in the associations.Method / Design: In Finland 11-year-old (at baseline) children participated in the PRO GREENS intervention in winter 2009. In control schools were 424 and in intervention schools 386 children (response rate 77%). Children filled in validated food frequency questionnaire assessing FV intake (times/day) and a validated questionnaire about factors influencing FV intake (availability of FV, liking for FV, preferences, self-efficacy to eat FV, attitudes towards FV and knowledge of the recommendations) both at baseline May 2009 and follow-up May 2010. Parental educational level (low, middle, high) was reported by the parents. Associations were examined with linear regression and mediation analyses.Results: The intervention increased fruit intake among girls but not among boys. Intervention increased also children’s knowledge of the recommendations. Since knowledge had no impact on boys’ fruit intake, the increase in knowledge mediated only intervention’s effect on girls’ fruit intake. Intervention increased children’s fruit intake similarly in all PEL groups.Intervention increased vegetable intake only in the middle PEL group but no intervention effect was noted among children with low or high PEL. Knowledge, the only factor which mediated the intervention’s effect on children’s vegetable intake, could not explain PEL differences in the effectivity of the intervention.Conclusions: Increase in knowledge was not a sufficient prerequisite to increase FV intake among boys or the lowest PEL group. More in depth analyses are needed to find out which factors to target in interventions to reach an effect in the target groups.
