Background

Overweight and obesity are considered as a public health priority, especially metabolically unhealthy overweight/obesity, due to their continuous increase worldwide and the possible associated health issues, in particular cardiometabolic diseases. Luxembourg has not been spared.

Objectives

The present work aims to investigate amongst the adult residents in Luxembourg:

1. the most recent prevalence of metabolically healthy and unhealthy overweight and obesity (2017), and the prevalence trends between 2007 and 2017.

2. the most recent prevalence of type 2 diabetes and prediabetes, hypertension and dyslipidemia (2017), and the prevalence trends (2007-2017).

Participants and Methods

Study-population and design

Data come from three population-based surveys: 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), and the European Health Examination Survey in Luxembourg, EHES-LUX (2013-2015).

Cross-sectional analyses of the three representative samples of adult residents of Luxembourg, 18 years of age or more, (ORISCAV-LUX, N=1432; EHES-LUX, N=1508; ORISCAV-LUX 2, N=1438) will be performed.

Data

Anthropometric data include weight, height, waist circumference and body mass index (BMI) assessments. Overweight and obesity will be defined according to the World Health Organisation definition. Abdominal obesity will be defined according to the International Diabetes Federation cutoffs established for the metabolic syndrome definition. Metabolically unhealthy overweight/obesity will be defined as previously described.

Clinical and biological data concern blood pressure, fasting glucose, triglycerides and high-density lipoprotein cholesterol (HDL-C) assessments. Information on drug treatment and/or previously diagnosed diseases will also be taken into consideration. Cardiometabolic diseases will be defined according to:

•the International Diabetes Federation (IDF) for prediabetes and type 2 diabetes,

•the American College of Cardiology (ACC) and American Heart Association (AHA) for hypertension,

•the Joint European Society of Cardiology for dyslipidemia.
