SummaryThe aim of this study was to find out whether differences exist in the physical development, nutritional status and psychosomatic status of children living in deprived regions of Hungary compared with the Hungarian national reference values. The Hungarian government’s decree No. 24/2003 created a complex indicator of social and economic conditions by which the country’s regions were graded into deprived and non-deprived regions. This study examined 3128 children (aged 3–18 years) living in the deprived regions and their biological status was compared with the national reference values (2nd Hungarian National Growth Study). Children’s body development was assessed via some absolute body dimensions. Nutritional status was estimated by BMI with children being divided into ‘underweight’, ‘normal’, ‘overweight’ and ‘obese’ categories. For children aged 7–18 years a standard symptoms list was used to characterize psychosomatic status. The subjects were asked to rate their health status as excellent, good, fair or poor. The body development of children living in these deprived regions was significantly retarded compared with the national references in the age groups 7–9 years and 14–17 years for boys and in the age groups 4–6 and 14–17 for girls. The prevalence of underweight was significantly higher in children and adolescents living in deprived regions (boys: 4.8%; girls: 5.9%) than the national references (boys: 2.9%; girls: 4.0%), while the prevalence of overweight and obese children did not differ between deprived regions (boys: 20.2%; girls: 19.8%) and the national references (boys: 21.5%; girls: 19.1%). Children and adolescents living in the deprived regions rated their health status worse, and experienced more psychosomatic complaints (abdominal discomfort and fear), than the national references. Although the majority of body dimensions of children in deprived regions were close to the 50th centile of the Hungarian national references, a sizeable minority (31%) were 0.20SD or more away from the median value, which has implications as to how social, medical and public welfare policy can be shaped.

Apparently Healthy

Background: For the establishment and monitoring of the immune status, CD4 count is critical. Objectives: To determine the CD4 count range of apparently healthy Nigerians resident in Ilorin and compare with the national value. Methods: An automated blood analyzer was used to determine the full blood count and CD4 count. The percentage of CD4 count was derived by using other variables. Results: Of the 1205 participants, the reference CD4 count (percentage of CD4) range for adult was 400 to 1288 cells/mm3 (19%-48%) and for children was 582 to 3652 cells/mm3 (17%-50%). CD4 count and percentage of CD4 were significantly ( P = .001) higher in females than in males, and the CD4 count declined significantly with increasing age ( r = −.174, P ≤ .0001). The percentage of CD4 count shows less variation with age ( r = −.051, P = .076). Adult residents of Ilorin had significantly lower absolute mean CD4 count (808 ± 260) than that of the national reference values of 847.0 ± 307.0 cells/mm3 ( P = .001). Conclusion: We therefore advocate the use of CD4 count range derived in this study is lower than that of the national reference values.

Quantitative Integration

In Europe, micronutrient dietary reference values have been established by (inter)national committees of experts and are used by public health policy decision-makers to monitor and assess the adequacy of diets within population groups. The approaches used to derive dietary reference values (including average requirements) vary considerably across countries, and so far no evidence-based reason has been identified for this variation. Nutrient requirements are traditionally based on the minimum amount of a nutrient needed by an individual to avoid deficiency, and is defined by the body’s physiological needs. Alternatively the requirement can be defined as the intake at which health is optimal, including the prevention of chronic diet-related diseases. Both approaches are confronted with many challenges (e. g., bioavailability, inter and intra-individual variability). EURRECA has derived a transparent approach for the quantitative integration of evidence on Intake-Status-Health associations and/or Factorial approach (including bioavailability) estimates. To facilitate the derivation of dietary reference values, EURopean micronutrient RECommendations Aligned (EURRECA) is developing a process flow chart to guide nutrient requirement-setting bodies through the process of setting dietary reference values, which aims to facilitate the scientific alignment of deriving these values.
