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.

Very low prevalence of iron deficiency among young French children: A national cross-sectional hospital-based survey

Although iron deficiency (ID) is considered the most frequent micronutrient deficiency in industrialized countries and is associated with impaired neurodevelopment when occurring in early years, accurate recent estimations of its prevalence are lacking. Our objective was to estimate ID prevalence and associated sociodemographic markers in young children in France. The Saturn-Inf national cross-sectional hospital-based survey recruited 3,831 French children <6 years old between 2008 and 2009 to assess lead poisoning prevalence and to establish a biobank. This secondary analysis measured serum ferritinemia (SF) in sera kept frozen at -80 °C for children with sufficient serum aliquots and C-reactive protein <10 mg/L. For the 657 participating children (17% of the Saturn-Inf study), the median age was 3.9 years (interquartile range: 2.2-5.1); 52% were boys. The median SF was 44 μg/L (interquartile range: 28-71). ID prevalence was 2.8% (95% confidence interval [1.7, 4.7]) and 3.2% (95% confidence interval [2.0, 5.1]) with an SF threshold of 10 and 12 μg/L, respectively. Low SF was significantly associated (p < .05) with mother being a migrant (32 vs. 45 μg/L for a mother born in France) or unemployed (37 vs. 50 μg/L for a mother employed). In this first national cross-sectional hospital-based study in France, ID prevalence was much lower than that in other French and European studies performed in underprivileged populations but close to the lowest values observed in other population-based studies in Europe.

["Cape Oxygen: moving towards self-care": a physical health promotion activity programme aimed at marginalised and disadvantaged groups]

OBJECTIVE

To study the feasibility of a physical activity and nutrition health promotion programme for low income populations (LIP).

SUBJECTS

9 structures which house and accommodate LIP, with 12-20 people per structure, aged 16-59 years old.

METHODS

1) preliminary investigation and research through interviews with LIP and the managers responsible for the structures, 2) on-site training of the stakeholders, managers and other professionals, 3) 2 training and information sessions on nutrition and 6 on physical activity.

MAIN RESULTS

Participation by session - 8 +/- 5 people (average +/- standard deviation). Participants reported effects according to their experiences such as: being valued, conquering their fears, commitment and self-engagement, satisfaction, respecting others, team spirit. Managers observed and reported their perception of the effects on the participants such as fulfilment, pleasure, strengthened sense of solidarity, liberty and comfortableness to speak freely and openly express themselves. The main challenges were related to the use of data collected during the preliminary investigation, the training of stakeholders and partners, and the relationships between LIP and their bodies.

CONCLUSIONS

Health promotion for LIP through physical activity is possible on the condition that: actors and professionals are trained to work with this vulnerable population, activities and capacities are adapted to meet expectations, difficulties related to poor body image are taking into account, and that the sustainability of the action is ensured.

Enquête épidémiologique sur la santé buccodentaire d'enfants âgés de 4 ans scolarisés en école maternelle

The departmental service of maternal and infantile protection (PMI) of Moselle (Lorraine region), together with the Paediatric Dentistry Department from Nancy University, organized a study of the dental health of 4-year-old children.

AIMS OF THE STUDY

To assess the children dental health; to evaluate parental knowledge of dental health; to identify the factors associated with caries amongst children.

MATERIAL AND METHODS

The study was a cross sectional observation. A random sample of 4-year-old children was selected among 11 586 children in nursery schools. The study was based on a clinical examination performed by a dentist and a structured questionnaire completed by parents.

RESULTS

The overall proportion of children affected by caries was 37.5%. The mean dmft score was 1.51 (sd = 2.82) and 11.6% of the children had caries which affected their upper incisors, a sign of early childhood caries. Only 6.2% had received dental treatment on at least 1 occasion. There was a clear disparity in dental health: 1 child out of 3 suffered from caries but 1 out of 2 children in priority education districts was affected, compared with only 1 out of 4 children coming from a rural area. The questionnaires completed by parents showed a lack of knowledge of dental health and inadequate use of current prevention facilities. The multivariate logistic regression analysis showed that the variables that were significantly associated with caries in 4 year-old children were the mother's education, the low social background, the level of consumption of drinks containing sugar by both children and parents, the consumption of fluoride, and the level of knowledge about fluoride.

CONCLUSION

Preventive measures must be developed in close relationship between pediatricians and dentists. Initial training of health care professionals has to be reinforced. Health care professionals in paediatrics are far more likely to meet mothers and young children than are dentists.

Prevalence and sociodemographic determinants of overweight in young French adolescents

BACKGROUND

The prevalence of overweight in adults and in children is increasing in most industrialised countries. Our purpose is to estimate the prevalence of overweight and obesity in a population of 12-year-old French adolescents and to analyse its association with different sociodemographic factors.

METHODS

A cross-sectional study was conducted in 2001 on a representative sample of sixth-grade adolescents (mean age 12.1 +/- 0.6 years) living in the Department of the Bas-Rhin (Eastern part of France). Height and weight were measured in 4326 adolescents. Overweight and obesity were defined as recommended by the International Obesity Task Force. Sociodemographic data were obtained for 3436 adolescents.

RESULTS

The prevalence of overweight was 22.7% (17.5% of moderate overweight and 5.2% of obesity) and it was not different by gender or by size of the commune of residence. Overweight was more frequent in low economic zones (p < 10(-4) in girls, p < 10(-2) in boys) and in public schools than in private schools (p < 10(-3) in girls). The prevalence of overweight was inversely associated with family income tax (p < 10(-3) in girls, p = 0.012 in boys), mother's (p = 10(-4) in girls, p = 10(-3) in boys) and father's (p = 0.001 in girls, p = 0.004 in boys) educational level. Multiple logistic regression analysis indicated an independent association of being overweight with low family income tax (p = 0.2195) and poor mother's educational level (p = 0.0193).

CONCLUSIONS

This study indicates that, as in other industrialised countries, much overweight and obesity are present in 12-year-old French adolescents. It suggests the existence of an influence of socio-economic factors with a predominant effect of the mother's educational level rather than the financial resources.
