Poor dietary habits and over-or under-consumption of calories, nutrients and non-nutrients have been associated with a number of chronic health complications, such as cardiometabolic diseases, but also cancer. As the Luxembourg population is facing many health issues at least partly related to dietary habits, it is important to understand the national dietary patterns and trends. These patterns and trends can be an important basis for suggesting changes toward more healthier dietary patterns.
In this regard, one may differentiate between a nutrient perspective such as the absolute amount or ratios of various macro-or micronutrients consumed, and a rather food pattern related view, such as the intake of fruits and vegetables.
The present work aims to investigate:
•the most recent dietary patterns and nutrient intake estimations in Luxembourg (2017),
•the general trends in dietary patterns and nutrient intake estimations, amongst adult residents in Luxembourg between 2007 and 2017,
•and the relations between dietary patterns and cardiometabolic and also other diseases will be investigated at the next stage, in order to gather evidence on dietary patterns and nutrient consumption related to reduced disease risk.
Materials and Methods
The first and second waves of the Observation of Cardiovascular Risk Factors in Luxembourg study, ORISCAV-LUX (2007-2009) and ORISCAV-LUX 2 (2016-2017), will be employed for this investigation. Cross-sectional analyses of the two representative samples of adult residents of Luxembourg, 18 years of age or more, (ORISCAV-LUX, N=1432; N=1508; ORISCAV-LUX 2, N=1438) will be performed. Data will be derived directly from the FFQs obtained from the two ORISCAV-LUX waves. Comparisons to recommended dietary intake, such as the DRIs (dietary reference intakes), especially the RDAs (recommended dietary allowances) will be made.
