In the study presented here, we evaluated the exposure of the German population aged 14-80 years to bis(2-ethylhexyl)phthalate (DEHP) from consumption of food by means of deterministic and probabilistic estimations. The study was performed on the basis of an extensive review of literature from around the world reporting measured data on DEHP in food, as(More)
BACKGROUND Equations published in the literature for predicting resting metabolic rate (RMR) in older individuals were exclusively derived from studies with small samples of this age group. AIM of the present investigation was therefore to compare the measured RMR of a relatively large group of older females and males with values for RMR calculated from(More)
BACKGROUND Validation of a food frequency questionnaire (FFQ) is important as incorrect information may lead to biased associations. Therefore the relative validity of an FFQ developed for use in the German Health Examination Survey for Adults 2008-2011 (DEGS) was examined. METHODS Cross-sectional comparisons of food consumption data from the FFQ and from(More)
The second German National Nutrition Survey (NVS II) aimed to evaluate food consumption and other aspects of nutritional behaviour of a representative sample of the German population, using a modular design with three different dietary assessment methods. To assess usual food consumption, 15,371 German speaking subjects 14-80 years of age completed a diet(More)
OBJECTIVES The aim of this study was to investigate whether an increase in total homocysteine (tHcy) concentration with increasing age is due to diminishing serum concentrations of pyridoxal-5-phosphate (PLP), vitamin B-12, and folate. The possible influence of different lifestyle factors on tHcy concentration was considered. METHODS Plasma tHcy, serum(More)
PURPOSE To further characterise the performance of the diet history method and the 24-h recalls method, both in an updated version, a comparison was conducted. METHODS The National Nutrition Survey II, representative for Germany, assessed food consumption with both methods. The comparison was conducted in a sample of 9,968 participants aged 14-80. Besides(More)
The German National Nutrition Monitoring (NEMONIT) is a longitudinal and nationwide study to assess changes in food consumption and nutrient intake in Germany. A sample of 1840 participants (baseline age: 14-80 years) was drawn from the nationally representative German National Nutrition Survey (NVS) II (2005-2007). The participants have been interviewed by(More)
OBJECTIVE The objective of the study was to identify predictors of BMI in German adults by considering the BMI distribution and to determine whether the association between BMI and its predictors varies along the BMI distribution. METHODS The sample included 9,214 adults aged 18-80 years from the German National Nutrition Survey II (NVS II). Quantile(More)
