Introduction of Potentially Allergenic Foods in the Infant's Diet during the First Year of Life in Five European Countries

Background: Little information is available on infants' age at first introduction of potentially allergenic foods as part of complementary feeding. We aimed to analyze age at the introduction of potentially allergenic foods in healthy term infants relative to recommendations in 5 European countries. Method: Recruitment was conducted from October 2002 to June 2004. A total of 1,678 infants {[}588 breastfed (BF) and 1,090 formula-fed (FF) infants] were studied. In 1,368 infants, at least one 3-day weighed food diary at the age of 1-9 and 12 completed months was available. Results: Six percent of BF infants and 13% of FF infants consumed some potentially allergenic food already prior to the recommended minimum age of 4 months, and 4% of BF infants and 11% of FF infants had already received gluten. There were significant differences in the timing of the introduction of potentially allergenic foods between the countries at the age of 4-6 months (p < 0.001). Conclusion: The time of first introduction of potentially allergenic foods in infants differed significantly between countries, and they were introduced much earlier than recommended in some countries. FF infants received potentially allergenic foods earlier than BF infants. Better information and counseling of parents is desirable. Copyright (C) 2011 S. Karger AG, Base

Are Commercial Complementary Food Distributions to Refugees and Migrants in Europe Conforming to International Policies and Guidelines on Infant and Young Child Feeding in Emergencies?

In 2015, more than one million migrants and refugees arrived in Europe. Commercial complementary foods, processed foods marketed for infants and young children 6-23 months of age, were distributed by various humanitarian actors along migrant routes and in European refugee camps. Unsolicited donations and distributions of commercial complementary food products were problematic and divergent from international policies on infant and young child feeding during humanitarian emergencies. Interim guidance regarding commercial complementary foods was published during the peak of the emergency but implemented differently by various humanitarian actors. Clearer and more technical specifications on commercial complementary foods are needed in order to objectively determine their suitability for operational contexts in Europe and emergency nutrition assistance in the future

Nutritional Adequacy of Commercial Complementary Cereals in Germany

Commercial cereals are among the first complementary foods fed to infants in Germany and elsewhere. The purpose of this national survey is to describe the nutritional adequacy of commercial complementary cereals. A comprehensive, cross-sectional survey of cereal manufacturer websites (n = 15) was conducted from March to April 2019. Food labels were analyzed for iron, zinc, iodine, sodium, and sugar contents in commercial complementary cereals, and ingredient lists were evaluated for whole grains and added sugars. Preparation instructions were evaluated for the type of liquid recommended for reconstitution. Among 164 commercial complementary cereals, few contain iron (n = 43, 26%), zinc (n = 23, 14%) or iodine (n = 43, 26%). Sodium contents fall within EU thresholds. Most cereals were single grain, containing only wheat (n = 54), with half of the products (n = 86, 52%) containing whole grains. The average carbohydrate content of dry cereals is 69 g/100 g ± 9 g of which 14 ± 15 g is sugar. Preparation instructions for breakfast porridges and cereals recommend formula or toddler milk, while few recommend human milk (n = 13, 18%). Few commercial complementary cereals contain appreciable amounts (at least 15% of daily reference values) of zinc, iron, or iodine. A quarter of cereal carbohydrates are sugar and one-third of the products contain added sugars. Future directives should stipulate minimum micronutrient levels, strictly regulate sugar contents, and include human milk among preparation instructions

Is growth in early childhood a window of opportunity for programming long-term health?

Background: Rapid growth characterises early childhood, with the highest weight gain in early infancy and continued relatively high gains during preschool years. Summary: Subnormal weight and length gain from birth to about 2 years of age predict increased childhood wasting and stunting, whereas excessive weight gain in infancy and early childhood is associated with increased later obesity. Breastfeeding attenuates the risk of high early weight gain and later obesity, adding another reason for promoting, protecting and supporting breastfeeding. Avoiding high infant protein intakes from infant formula and complementary foods is strongly recommended since it markedly reduces later obesity and adiposity. This can be achieved by avoiding cows’ and other animal milks as a drink in infancy and choosing infant formula with a low protein content, more similar to breastmilk, for infants not (fully) breastfed. High weight gain in toddlers is also associated with increased later obesity, predicted by overfeeding, high intakes of sugary foods and beverages, and high intakes of protein, particularly animal protein. In an ongoing controlled trial in Germany and Spain, we randomised 1,618 toddlers to milk drinks in the second year of life providing protein contents either similar to cows’ milk or more similar to human milk. First results show high protein milk inducing high weight and length gains deviating from normal growth trajectories, whereas reduced protein intakes support weight and length growth matching WHO growth standards. Follow-up until early school age is ongoing to explore a potential impact on later growth and overweight risk. Key messages: Avoiding rapid weight gain in infancy and toddlerhood can reduce later obesity risk. Promoting, protecting and supporting breastfeeding and avoidance of high animal protein intakes in early childhood can contribute to reaching this goal

Invasive Haemophilus influenzae infections in Germany: impact of non-type b serotypes in the post-vaccine era

Background: Haemophilus influenzae type b (Hib) vaccination led to a significant decrease in invasive bacterial infections in children. The aim of this study was to assess a potential shift to more non-type b invasive infections in a population with high Hib vaccination coverage and to compare the burden of suffering between children with Hib, capsulated non-b and non-capsulated Hi infections. Methods: Cases with confirmed invasive Hi infections were ascertained through two independent nationwide active surveillance systems in 1998–2005. Information on possible predisposing conditions and clinical information was available from 2001 onwards. Results: The total number of reported non-type b Hi cases varied between 10 cases in 1998, 27 in 2000 and 14 in 2005. In each year, non-capsulated serotypes outnumbered capsulated non-type b ones. 192 cases were detected in 2001–2005, more than one half was non-type b and 88% of the non-type b cases were non-capsulated. For cases with Hib/capsulated non-type b infections the most common clinical presentation was meningitis (67% each); 89%/78% had no potential predisposing condition, 75%/72% completely recovered from disease and 6% (each) died. In contrast, meningitis was diagnosed in 34% of the non-capsulated Hi infections, septicaemia in 28% and pneumonia 21%; 62% had no potential predisposing condition, 83% completely recovered and 3% died. Conclusion: There was no increase in non-type b Hi invasive infections during 8 years of active surveillance in Germany. Invasive disease due to non-type b Hi is not confined to children with risk factors. In patients with capsulated non-type b Hi infections the proportion of meningitis cases is similar to Hib, but double as high as in non-capsulated Hi

Regulation of early human growth: impact on long-term health

Growth and development are central characteristics of childhood. Deviations from normal growth can indicate serious health challenges. The adverse impact of early growth faltering and malnutrition on later health has long been known. In contrast, the impact of rapid early weight and body fat gain on programming of later disease risk have only recently received increased attention. Numerous observational studies related diet in early childhood and rapid early growth to the risk of later obesity and associated disorders. Causality was confirmed in a large, double-blind randomised trial testing the ‘Early Protein Hypothesis'. In this trial we found that attenuation of protein supply in infancy normalized early growth and markedly reduced obesity prevalence in early school age. These results indicate the need to describe and analyse growth patterns and their regulation through diet in more detail and to characterize the underlying metabolic and epigenetic mechanisms, given the potential major relevance for public health and policy. Better understanding of growth patterns and their regulation could have major benefits for the promotion of public health, consumer-orientated nutrition recommendations, and the development of improved food products for specific target populations.</jats:p

Animal and plant protein intake during infancy and childhood DNA methylation:a meta-analysis in the NutriPROGRAM consortium

Background: Higher early-life animal protein intake is associated with a higher childhood obesity risk compared to plant protein intake. Differential DNA methylation may represent an underlying mechanism. Methods: We analysed associations of infant animal and plant protein intakes with DNA methylation in early (2−6 years, N = 579) and late (7̄−12 years, N = 604) childhood in two studies. Study-specific robust linear regression models adjusted for relevant confounders were run, and then meta-analysed using a fixed-effects model. We also performed sex-stratified meta-analyses. Follow-up analyses included pathway analysis and eQTM look-up. Results: Infant animal protein intake was not associated with DNA methylation in early childhood, but was associated with late-childhood DNA methylation at cg21300373 (P = 4.27 × 10¯8, MARCHF1) and cg10633363 (P = 1.09 × 10¯7, HOXB9) after FDR correction. Infant plant protein intake was associated with early-childhood DNA methylation at cg25973293 (P = 2.26 × 10−7, C1orf159) and cg15407373 (P = 2.13 × 10−7, MBP) after FDR correction. There was no overlap between the findings from the animal and plant protein analyses. We did not find enriched functional pathways at either time point using CpGs associated with animal and plant protein. These CpGs were not previously associated with childhood gene expression. Sex-stratified meta-analyses showed sex-specific DNA methylation associations for both animal and plant protein intake. Conclusion: Infant animal protein intake was associated with DNA methylation at two CpGs in late childhood. Infant plant protein intake was associated with DNA methylation in early childhood at two CpGs. A potential mediating role of DNA methylation at these CpGs between infant protein intake and health outcomes requires further investigation.</p

Specific Varicella-Related Complications and Their Decrease in Hospitalized Children after the Introduction of General Varicella Vaccination: Results from a Multicenter Pediatric Hospital Surveillance Study in Bavaria (Germany)

Hagemann C, Krämer A, Grote V, Liese JG, Streng A. Specific Varicella-Related Complications and Their Decrease in Hospitalized Children after the Introduction of General Varicella Vaccination: Results from a Multicenter Pediatric Hospital Surveillance Study in Bavaria (Germany). Infectious Diseases and Therapy. 2019;8(4):1-15.Background Universal varicella vaccination (UVV) for children introduced in Germany in 2004 resulted in a significant overall decline of varicella-related hospitalizations (VRHs). We investigated the incidence of specific types of varicella-related complications (VRCs) in hospitalized children and the impact of UVV on VRCs during the first 7 years of UVV. Methods Children < 17 years of age hospitalized with an ICD-10-based (International Classification of Diseases, 10th Revision) discharge diagnosis of varicella were identified as VRH in pediatric hospitals in Bavaria by annual standardized data queries of the hospital databases (2005–2011). For each VRH, the hospitals reported basic demographic data, duration of hospital stay, all diagnostic and procedural codes, and outcome. VRCs were reported overall, per year, and by immune status. Complication rates were calculated as mean number per complication category per hospital and per year; VRC trends over time were assessed by linear regression. Results Between 78% (2005) and 61% (2011) of Bavarian hospitals participated and reported a total of 1263 VRHs. Specific VRCs were reported in 954 (76%) children. Complication rates per hospital and year decreased from 6.7 [95% confidence interval (CI): 5.1–8.3] in 2005 to 1.5 (95% CI: 0.8–2.3) in 2011, with the strongest reduction of 90% in children < 5 years of age from 5.3 (95% CI: 4.0–6.6) in 2005 to 0.5 (95% CI: 0.1–0.9) in 2011. Significant decreases were observed for children with upper respiratory tract (URT, by 97%), lower respiratory tract (LRT, by 90%), skin (by 81%), gastrointestinal (by 78%), and neurologic (by 65%) VRCs. Forty-eight children with VRCs were immunocompromised; their annual rate decreased by 87%. Discussion Corresponding to increasing varicella vaccination coverage in the population, the incidence of VRC decreased by 77% from 2005 to 2011, with the most substantial decrease in the target group for UVV. Conclusion Within 7 years, UVV in Germany led to a decrease of about 77% of all types of VRCs, with the highest reductions observed for VRCs of the respiratory tract
