Background/purposeThe number of dietary exposure assessment studies focussing on children is very limited. Children are however a vulnerable group due to their higher food consumption level per kg body weight. Therefore, the EXPOCHI project aims [1] to create a relational network of individual food consumption databases in children, covering different geographical areas within Europe, and [2] to use these data to assess the usual intake of lead, chromium, selenium and food colours.MethodsEXPOCHI includes 14 food consumption databases focussed on children (1-14 y old). The data are considered representative at national/regional level: 14 regions covering 13 countries. Since the aim of the study is to perform long-term exposure assessments, only data derived from 24 hr dietary recalls and dietary records recorded on at least two non-consecutive days per individual were included in the dietary exposure assessments. To link consumption data and concentration data of lead, chromium and selenium in a standardised way, categorisation of the food consumption data was based on the food categorisation system described within the SCOOP Task report 3.2.11. For food colours, the food categorisation system specified in the Council Directive 94/36/EC was used.ConclusionThe EXPOCHI project includes a pan-European long-term exposure assessment of lead, chromium, selenium and food colours among children living in 13 different EU countries. However, the different study methods and designs used to collect the data in the different countries necessitate an in-depth description of these different methods and a discussion about the resulting limitations.

Given that commercial complementary food (CF) can contain high levels of added sugar, a high consumption may predispose to a preference for sweet taste later in life. This study examined cross-sectional associations between commercial CF consumption and added sugar intake in infancy as well as its prospective relation to added sugar intake in pre-school and primary-school age children. In all, 288 children of the Dortmund Nutritional and Anthropometric Longitudinally Designed Study with 3-d weighed dietary records at 0·5 and 0·75 (infancy), 3 and 4 (pre-school age) and 6 and 7 years of age (primary-school age) were included in this analysis. Individual commercial CF consumption as percentage of total commercial CF (%cCF) was averaged at 0·5 and 0·75 years. Individual total added sugar intake (g/d, energy percentage/d) was averaged for all three age groups. Multivariable logistic and linear regression models were used to analyse associations between %cCF and added sugar intake. In infancy, a higher %cCF was associated with odds for high added sugar intake from CF and for high total added sugar intake (>75th percentile, P < 0·033). Prospectively, a higher %cCF was related to higher added sugar intake in both pre-school (P < 0·041) and primary-school age children (P < 0·039), although these associations were attenuated in models adjusting for added sugar intake in infancy. A higher %cCF in infancy may predispose to higher added sugar intake in later childhood by virtue of its added sugar content. Therefore, offering home-made CF or carefully chosen commercial CF without added sugar might be one strategy to reduce sugar intake in infancy and later on.

In this document, we report on the long-term dietary exposure to 40 different food colours in young children living in 11 European countries. Food consumption data of children aged 1 up to 10 years (in Cyprus 11 up to 14 years) were combined with food colour concentrations as supplied by EFSA using statistical models to calculate exposure. Food consumption data were all categorised according to a harmonised system to allow for linkage with food colour concentration data in a standardised way. Two different exposure scenarios were calculated for each food colour: the maximum permitted usage levels in the relevant Community legislation (here called the "MPL scenario") and the actual maximum reported usage patterns (here called the "maximum usage level scenario"). For some food colours extra scenarios were considered depending on the percentage of coating (5 or 20%), e.g. food colours permitted in the coating of chocolate products. For lycopene, five different scenarios were considered. Although the results showed differences in exposure between countries, such differences should be interpreted with caution, as different methodological limitations rather than true exposure differences might be partly responsible for such findings. It is clear from this exercise that food consumption data in different countries can be categorised in a standard way to allow for harmonised exposure modelling.
