Vitamin B, vitamin B and total homocysteine status in children and their associations with dietary intake of B-vitamins from different food groups: the Healthy Growth Study.

Purpose: To examine the associations between the dietary intakes of certain B-vitamins from different food sources with the relevant plasma status indices in children.

Methods: A representative subsample of 600 children aged 9-13 years from the Healthy Growth Study was selected. Dietary intakes of vitamins B, B, B and folate derived from different food sources were estimated.

Comparison of different approaches to calculate nutrient intakes based upon 24-h recall data derived from a multicenter study in European adolescents.

Purpose: The European "Healthy Lifestyle in Europe by Nutrition in Adolescence" (HELENA) project evaluated two different approaches to harmonize the matching procedures between 24-h recall data and food composition databases. In the first approach, the 24-h recall data were linked to the local/national food composition databases using standardized procedures, while in the second approach, the 24-h recall data were linked to the German BLS database which includes a larger food list. The aim of this paper was to compare the intakes of energy and eight nutrient components calculated via both approaches.

Breakfast habits among European adolescents and their association with sociodemographic factors: the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) study.

Objective: To describe breakfast habits at food group level in European adolescents and to investigate the associations between these habits and sociodemographic factors.

Design: Cross-sectional study.

Setting: Secondary schools from nine European cities participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) Study.
