Background: Energy misreporting can lead to systematic bias in nutrition surveys. The aim of this study was to identify misreporting and to describe Low-Energy-Reporter (LER) with regard to its sociodemographic characteristics. Furthermore, it should be investigated whether certain food groups are more affected by low-energy reporting and how this affects the nutrient intake of the population.Methods: The investigation was based on 943 weighed food records of the NVS II. LER were identified using various estimation equations. Differences in food intake were investigated absolute and adjusted for energy intake. The nutrient supply was compared with the D-A-CH reference values.Results: The prevalence of misreporting depends on the approach used. Low-energy reporting is associated with overweight, women, youngest age groups and a low socio-economic status. LER record less fat- and sugar-rich food. LER have a higher intake of energy from proteins and, in absolute terms, the intake of macro- and micronutrients and dietary fibre from LER is significantly lower. The proportion of those who do not reach the D-A-CH reference values for micronutrients is significantly higher among LER. Thus, low-energy reporting leds to an overestimation of the prevalence of inadequate micronutrient intake.Conclusion: For future studies it is useful to apply consistent standards for the identification of misreporting, as well as to measure physical activity objectively and above all to reduce misreporting. For this purpose, the great potential of information and communication technology can be used.
