Derivation of occupational exposure limits: Differences in methods and protection levels.

Frameworks for deriving occupational exposure limits (OELs) and OEL-analogue values (such as derived-no-effect levels [DNELs]) in various regulatory areas in the EU and at national level in Germany were analysed. Reasons for differences between frameworks and possible means of improving transparency and harmonisation were identified. Differences between assessment factors used for deriving exposure limits proved to be one important reason for diverging numerical values.

Distributions for time, interspecies and intraspecies extrapolation for deriving occupational exposure limits.

This work aimed at improving the empirical database of time (i.e., exposure duration), interspecies and intraspecies extrapolation when deriving occupational exposure limits (OELs).

Nutrient Adequacy and Associated Factors in a Nationwide Sample of German Toddlers.

Objectives: Nutrition in toddlerhood may have short- and long-term impacts on health and nutrition behavior. The objectives of the present article are to describe intake of energy and nutrients from the end of infancy to toddlerhood, and to examine dietary and socioeconomic factors (socioeconomic status [SES]) associated with total nutrient adequacy measured by a nutrient-based index (Nutrient Quality Index [NQI]).

Methods: In the German Representative Study of Toddler Alimentation from 2008, 7-day estimated dietary records were collected cross-sectionally from toddlers ages 10 to 36 months (n = 525).

Relative validity of a 3 d estimated food record in German toddlers.

Objective: To determine the relative validity of a 3 d estimated food record (EFR) used to assess energy and nutrient intakes in toddlers, using a 3 d weighed food record (WDR) as the reference method.

Design: Parents reported the food and beverage intakes of their children using an EFR concurrently with a WDR over three consecutive days. Estimation of mean differences, Spearman correlation coefficients, cross-classifications and Bland-Altman plots were used to assess the agreement between the intakes of energy and fourteen nutrients obtained from the EFR and the WDR.

Anthocyanins in the diet of children and adolescents: intake, sources and trends.

Purpose: Anthocyanin intake estimations in large cohorts include almost exclusively adults. For the purpose of early dietary prevention, however, it is of great interest to estimate anthocyanin intake of children and adolescents.

Methods: Anthocyanidin content values from the USDA Database (excluding the values for bananas and nuts) were assigned to foods consumed by 4-18-year-old participants of the DONALD Study.

Liking of anthocyanin-rich juices by children and adolescents.

There is evidence that a diet rich in plant foods is protective against cardiovascular disease and cancer, partly attributable to secondary plant metabolites such as anthocyanins, a colourful group of flavonoids. As at present children and adolescents do not consume the recommended amounts of fruits and vegetables, one possible way of increasing intake, and particularly intake of anthocyanins, may be an anthocyanin-rich juice, since fruit juice is popular with young Germans. We produced eight different fruit products (six juices, two smoothies), and conducted hedonic tests with participants from the DONALD Study.

Anthocyanins in the diet of infants and toddlers: intake, sources and trends.

Purpose: Anthocyanins, a colourful group of flavonoids in many fruits and vegetables, are proposed to provide positive impact on human health. However, intake estimations have almost exclusively been conducted in adult populations. As infants and toddlers are a promising age group for health promotion, we examined their anthocyanin intake (as anthocyanidins), food sources and trends of age and time in anthocyanidin density.

Dietary intake and plasma concentrations of PUFA and LC-PUFA in breastfed and formula fed infants under real-life conditions.

Background: The breastfed infant is usually used as standard for formula feeding, also regarding long-chain polyunsaturated fatty acids (LC-PUFA). Here, plasma fatty acid concentrations in formula fed infants and the effects of LC-PUFA supplementation were investigated under real-life conditions.

Method: Term healthy infants being fully milk fed until the age of 4 months were categorized as breast milk "BM" (n = 73) if consuming >95% of energy from breast milk or formula (F) if consuming >95% of energy from formula subdivided into formula without (F-) (n = 15) and with LC-PUFA supplementation (F+) (n = 15).
