The Subjective Cost of Young Children: A European Comparison

Understanding child-related costs is crucial given their impact on fertility and labour supply decisions. We explore the subjective cost of young children in Europe by analysing the effect of child births on parents’ self-reported ability to make ends meet, and link it to changes in objective economic well-being such as income, benefits, and employment. The study is based on EU-SILC longitudinal data for 30 European countries from 2004 to 2019, enabling comparisons between country groups of different welfare regimes. Results show that newborns decrease subjective economic well-being in all regions, yet with economies of scale for the number of children. Mediation analyses reveal that the substantial labour income losses of mothers (indirect costs) explain only a small part of subjective child costs. In the first year after birth, these losses are mostly compensated for via public transfers or increased labour income of fathers, except in regions where women take extensive parental leave. This suggests that the initial drop in subjective economic well-being after childbirth is caused by increased expenses due to the birth of a child (direct costs) and other drivers such as stress that are reflected in the self-reported indicator.

A multilevel approach to ECEC policies and intensity of formal childcare participation of young children in Europe

This study explores the relationship between ECEC participation for young children (0–2-year-olds) and ECEC policies using multilevel Tobit modelling. At the micro-level, the socio-ecological model is employed to control for the individual- and family-related circumstances, using the EU-SILC data from 2014; and at the macro-level, policy measures regarding the provision, regulation, and financing of ECEC are tested. Particular attention is paid to the role of these policies on two major sources of disadvantage: low-income status and migration background. The findings reveal that hourly ECEC participation is higher in countries where the legal entitlement to ECEC and free ECEC provision start early, the ECEC system is unitary, the structural quality standards are high, and public spending per child is high, and the parental fees are low. While universal access and structural quality policies are particularly favourable for disadvantaged children, high public spending and low parental or private financing for ECEC do not correlate with higher use by disadvantaged children, confirming the risk of a Matthew effect with the way ECEC is financed.

Iron status of young children in Europe

Iron deficiency (ID) is common in young children aged 6-36 mo. Although the hazards associated with iron deficiency anemia (IDA) are well known, concerns about risks associated with excess iron intake in young children are emerging. To characterize iron status in Europe, we describe the prevalence of ID, IDA, iron repletion, and excess stores with the use of published data from a systematic review on iron intake and deficiency rates, combined with other selected iron status data in young European children. Various definitions for ID and IDA were applied across studies. ID prevalence varied depending on socioeconomic status and type of milk fed (i.e., human or cow milk or formula). Without regard to these factors, ID was reported in 3-48% of children aged ≥12 mo across the countries. For 6- to 12-mo-old infants, based on studies that did not differentiate these factors, ID prevalence was 4-18%. IDA was <5% in most studies in Northern and Western Europe but was considerably higher in Eastern Europe (9-50%). According to current iron status data from a sample of healthy Western European children aged 12-36 mo, 69% were iron replete, and the 97.5th percentile for serum ferritin (SF) was 64.3 μg/L. In another sample, 79% of 24-mo-old children were iron replete, and the 97.5th percentile for SF was 57.3 μg/L. Average iron intake in most countries studied was close to or below the UK's Recommended Dietary Allowance. In conclusion, even in healthy European children aged 6-36 mo, ID is still common. In Western European populations for whom data were available, approximately three-quarters of children were found to be iron replete, and excess iron stores (SF >100 μg/L) did not appear to be a concern. Consensus on the definitions of iron repletion and excess stores, as well as on ID and IDA, is needed.

Health and economic outcomes of introducing the new MenB vaccine (Bexsero) into the Italian routine infant immunisation programme.

IntroductionIn January 2013 a novel type of multicomponent protein-based vaccine against group B meningococcal disease was licensed by the European Medicines Agency. With the widespread use of the meningococcal serogroup C conjugate vaccines, serogroup B remains now the major cause of bacterial meningitis and septicaemia in young children in Europe. The aim of this study is to investigate the health and the economic outcomes of MenB vaccine introduction into the Italian routine mass vaccination programme.MethodsThe present work is structured in two main parts. Firstly, we assess the epidemiological burden of group B meningococcal disease using official hospitalisation and notification data from two of the most populated Italian regions (Lombardia and Piemonte) during a 6-year study period (2007-2012). Secondly, we evaluate the cost-effectiveness of the immunisation programme in Italy from the public health payer perspective under base case parameters assumptions and performing a comprehensive sensitivity analysis to assess the robustness and the uncertainty of our model results.ResultsMenB serotype is responsible for 59% of the 341 cases of Invasive Meningococcal Disease in Lombardia and Piemonte. Incidence rate for MenB infection is estimated to be 0.21/100,000/y resulting at the highest level in children ≤4 years of age. Although the new MenB vaccine can potentially prevent about one third of the disease cases in the Italian population, model results show this strategy is unlikely to be cost-effective (ICER value over €350,000/QALY) with a vaccine that prevents disease only. These results are robust under most of the sensitivity scenarios except when allowing for lower discount rates.DiscussionThe introduction of the novel vaccine into the routine immunisation schedule needs to be carefully evaluated. The new MenB vaccine has the potential to reduce the disease burden at the population level. However, from the Italian Health Service perspective, the immunisation programme is unlikely to be cost-effective at the current incidence levels and vaccine price.

Blood lipids among young children in Europe. Results from the European IDEFICS study

Measurement of cholesterol and triglyceride (TG) fractions in blood has become standard practice in the early detection of atherosclerotic disease pathways. Considerable attention is given nowadays to the presence of these risk factors in children and to start preventive campaigns early in life. In this context, it is imperative to have valid comparative frameworks for interpretation of lipid levels. The aim of this study is to present sex- and age-specific reference values on blood lipid levels in European children aged 2.0–10.9 years. Fasting blood was obtained via either venipuncture or capillary sampling. In 13 579 European non-obese children (50.3% boys), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), TG and TC/HDL-C ratio levels were measured with a point-of-care analyser (Cholestech). Sex- and age-specific reference values were computed with the GAMLSS method with the statistical software R. Reference curves and 1st, 3rd, 10th, 25th, 50th, 75th, 90th, 97th and 99th percentile values are presented. HDL-C showed a positive trend with age, from 2 years onwards, but was relatively stable above the age of 7. For LDL-C and TC, linear but small age-related trends were seen. The TC/HDL-C values showed a gradual negative trend from the age of 2 up to 6 and were relatively stable afterwards. For TG, no age trend was found (P=0.285). Boys had higher mean HDL-C values than girls (1.414 vs 1.368 mmol l−1), and lower TC, LDL-C, TC/HDL-C and TG values (3.981 vs 4.087 mmol l−1; 2.297 vs 2.435 mmol l−1; 2.84 vs 3.01mmol l−1; and 0.509 vs 0.542 mmol l−1, respectively). These new and recent references could serve as a European orientation of blood lipid values in children in the context of standard medical practice and for the purpose of public health screening.

Objectively measured physical activity in European children: the IDEFICS study.

To provide sex- and age-specific percentile values for levels of physical activity (PA) and sedentary time of European children aged 2.0-10.9 years from eight European countries (Sweden, Germany, Hungary, Italy, Cyprus, Spain, Belgium and Estonia). Free-living PA and sedentary time were objectively assessed using ActiGraph GT1M or ActiTrainer activity monitors in all children who had at least 3 days' worth of valid accelerometer data, with at least 8 h of valid recording time each day. The General Additive Model for Location Scale and Shape was used for calculating percentile curves. Reference values for PA and sedentary time in the European children according to sex and age are displayed using smoothed percentile curves for 7684 children (3842 boys and 3842 girls). The figures show similar trends in boys and girls. The percentage of children complying with recommendations regarding moderate-to-vigorous physical activity (MVPA) is also presented and varied considerably between sexes and country. For example, the percentage of study participants who were physically active (as assessed by MVPA) for 60 or more minutes per day ranged from 2.0% (Cyprus) to 14.7% (Sweden) in girls and from 9.5% (Italy) to 34.1% (Belgium) in boys. This study provides the most up-to-date sex- and age-specific reference data on PA in young children in Europe. The percentage compliance to MVPA recommendations for these European children varied considerably between sexes and country and was generally low. These results may have important implications for public health policy and PA counselling.

Early Behavioral Self-Regulation, Academic Achievement, and Gender: Longitudinal Findings From France, Germany, and Iceland

Research suggests that behavioral self-regulation skills are critical for early school success, but few studies have explored such links among young children in Europe. This study examined the contribution of early self-regulation to academic achievement gains among children in France, Germany, and Iceland. Gender differences in behavioral self-regulation skills were also explored. A total of 260 children were followed longitudinally over one to two years (average age at Wave 1 was 74.5 months). Behavioral self-regulation was assessed using a structured direct observation (Head-Toes-Knees-Shoulders task) and assessment. Multilevel analyses revealed that higher levels on both ratings of self-regulation predicted higher academic skills after controlling for gender, age, maternal education, and previous achievement, but the relations depended on the cultural context. Teacher ratings were more consistently related to achievement gains than directly assessed behavioral self-regulation. Girls outperformed boys only in Iceland. We discuss universal and culture-specific findings and implications for educational practices.

Scientific Opinion on nutrient requirements and dietary intakes of infants and young children in the European Union

Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver a Scientific Opinion on the nutrient requirements and dietary intakes of infants and young children in the European Union. This Opinion describes the dietary requirements of infants and young children, compares dietary intakes and requirements in infants and young children in Europe and, based on these findings, concludes on the potential role of young-child formulae in the diets of infants and young children, including whether they have any nutritional benefits when compared with other foods that may be included in the normal diet of infants and young children. The Panel concluded on the levels of nutrient and energy intakes that are considered adequate for the majority of infants and young children, and evaluated the risk of inadequate nutrient intakes in infants and young children in living Europe. Dietary intakes of alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), iron, vitamin D and iodine (in some European countries) are low in infants and young children living in Europe, and particular attention should be paid to ensuring an appropriate supply of ALA, DHA, iron, vitamin D and iodine in infants and young children with inadequate or at risk of inadequate status of these nutrients. No unique role of young-child formulae with respect to the provision of critical nutrients in the diet of infants and young children living in Europe can be identified, so that they cannot be considered as a necessity to satisfy the nutritional requirements of young children when compared with other foods that may be included in the normal diet of young children (such as breast milk, infant formulae, follow-on formulae and cow's milk).

“The blessings of civilisation”: nineteenth‐century missionary infant schools for young native children in three colonial settings – India, Canada and New Zealand 1820s–1840s

In the context of missionary endeavours of the early nineteenth century there were considerable similarities in the religious and education blueprints for providing the “blessings of civilisation” to the young native “heathen” child in various parts of the British Empire. The three case studies presented illustrate a relatively undocumented aspect of missionary work concerning the adaptation of new European ideas for schooling very young children in so‐called infant schools. The comparative focus on the shared aspects of their colonial experience is illuminating of both the pervasiveness of missionary endeavours and the diversity of contexts to which those ideals were applied. This paper provides an overview of the context of new ideas for educating young children in Europe alongside the focus of British missionary endeavour towards its expanding colonial empire in the early years of the nineteenth century. Short illustrative case studies are presented in relation to the missionary infant schools in British India, Canada and New Zealand, all established in parallel during the 1820s–1840s. The characteristic of all infant schools, whether amongst the poor in Britain or the heathen in its colonies, was to create an ordered environment apart from the perceived disorder of the child’s home, and the focus was to produce an educable and orderly child. Each case study provides a different facet of the missionary quest to save children from their heathen ways through schooling.

Estimated mortality and hospital admission due to rotavirus infection in the WHO European region

In 2006 two rotavirus vaccines were licensed for use in young children in Europe. This study aimed to estimate the mortality and hospital admissions due to rotavirus in children aged <5 years in the WHO European region using data from routine sources and published literature. We grouped 49/52 countries in the region by their World Bank Gross National Income (GNI) per capita. We obtained for children aged <5 years: populations, hospital discharges for diarrhoeal disease, estimated mortality rates and the percentage of deaths attributable to diarrhoeal disease, from WHO data sources or published literature, and combined them to estimate country-specific diarrhoeal disease mortality. Rotavirus-attributable percentages of hospital admissions due to diarrhoeal disease were obtained through a literature search, and an income-group median applied to countries in each GNI category. In the countries we studied in the WHO European region, rotavirus infection causes an estimated 6550 deaths (range 5671-8989) and 146 287 (range 38 374-1 039 843) hospital admissions each year in children aged <5 years. Hospital admission rates were similar across income groups (medians 2.0, 2.8, 4.2 and 1.9/1000 per year in low-, lower-middle-, upper-middle- and high-income countries, respectively). Seven countries, mostly in the low- and lower-middle-income groups, accounted for 93% of estimated deaths. Disease burden varied dramatically by income level in the European region. Rotavirus vaccination in Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan and Turkey could potentially prevent 80% of all regional rotavirus deaths. Data from low-income countries is still sparse, and improved disease burden studies are required to better inform regional vaccine policy.

Intussusception Among Young Children in Europe

Intussusception, a potentially lethal condition with poorly understood etiology, is the most common cause of acute intestinal obstruction in children younger than 5 years old. In some cases, the condition has been associated with administration of the first licensed rotavirus vaccine, the reassortant rhesus-human tetravalent rotavirus vaccine (RRV-TV; RotaShield). No such association has to date been reported from large phase III safety trials with new rotavirus vaccines. As 2 new, live-attenuated oral rotavirus vaccines are currently under review for approval by the European Union regulatory authorities, a review of the clinical, etiologic and epidemiologic aspects of intussusception in Europe is urgently needed. We conducted a review of Medline literature, published from 1995 onwards on intussusception in the World Health Organization's European Region. The results are compared with data from previous reviews and other regions. The classic triad of intussusception symptoms (abdominal pain, abdominal mass, bloody stools) was present in 29-33% of patients according to the medical literature reviewed. Conservative treatment (barium, air or saline enema) was the rule (81% of cases), and few complications were observed during treatment. Treatment outcome was generally favorable, with recurrence occurring in approximately 1 in 10 patients, and only 1 death reported. Structural lead points were seen in 3% of patients; no other reliable data on the etiology of intussusception were found. The incidence of acute intussusception in young children in Europe, according to 6 heterogeneous hospital-based studies, ranged from 0.66 to 2.24 per 1000 children in inpatient departments and from 0.75 to 1.00 per 1000 children in emergency departments. Peak incidences were found in children 3-9 months of age. There are still gaps in our knowledge of intussusception with respect to its etiology and especially by which mechanisms RRV-TV might have caused it to occur. Data from regions outside Europe showed that rotavirus infection and disease are not associated with intussusception. As new rotavirus vaccines become available for use in Europe, postlicensure surveillance for intussusception is indicated and may be instrumental in further understanding the epidemiology of this condition and in further assessing the safety of future vaccines.

A missing link in the hygiene hypothesis?

The incidence of childhood Type I (insulin-dependent) diabetes mellitus has risen in parallel with that of childhood asthma, and the hygiene hypothesis proposes that this is due to reduced stimulation of the immune system by early intercurrent infection. If so, this protective effect is probably mediated by regulatory T lymphocytes. Co-evolutionary partners might have contributed to the development of this form of response, and parasites and the indigenous biota of the gut are plausible candidates. Helminths inhibit the development of atopic disease via induction of regulatory T cells and secretion of Il-10, and pinworms inhibit diabetes development in the non-obese diabetic (NOD) mouse. The most successful human helminth of the western world is the pinworm Enterobius vermicularis, and some 50% of young children in Europe and North America may have been infested around the middle of the twentieth century. Pinworms are benign, usually asymptomatic, and may have immunomodulatory properties that protect against the development of immune-mediated disorders including diabetes and asthma. Their decline in response to improved living conditions might explain a number of features of the epidemiology of childhood atopy and diabetes. The proposed role would be one of immunomodulation rather than disease induction, possibly mediated by interaction with other influences upon the development of the mucosal immune system. This hypothesis could be tested in case-control studies by the development of serological markers or skin testing. If confirmed, identification of the underlying mechanisms could open the way to new forms of immune intervention.

The contribution of specific pneumococcal serogroups to different disease manifestations: implications for conjugate vaccine formulation and use, part II.

To assess whether certain serogroups of Streptococcus pneumoniae are preferentially associated with specific disease manifestations, we analyzed all recent pneumococcal disease studies and assessed the relative frequency of isolation of each serogroup by clinical site (as a proxy for different disease states). In all age groups, serogroups 1 and 14 were more often isolated from blood, and serogroups 6, 10, and 23 were more often isolated from cerebrospinal fluid (CSF); in young children, serogroups 3, 19, and 23 were more often isolated from middle ear fluid (MEF). Serogroups represented in conjugate vaccines were isolated slightly less frequently from CSF than from blood or MEF. Nonetheless, serogroups in the 9-valent conjugate vaccine formulation still comprised approximately 75% of pneumococcal isolates from the CSF of young children in Europe and in the United States and Canada. These analyses indicate that pneumococcal conjugate vaccines could potentially prevent a substantial proportion of episodes of bacteremic disease, pneumonia, meningitis, and otitis media, especially in young children.
