The Netherlands Epidemiology of Obesity Study (NEO)
The Netherlands Epidemiology of Obesity (NEO) study is a population-based cohort study in 6671 men and women aged 45 to 65 years, with an oversampling of individuals with a BMI of 27 kg/m2 or higher. The NEO study is designed to investigate pathways that lead to common diseases and conditions.
Men and women aged between 45 and 65 years with a self-reported BMI of 27 kg/m2 or higher living in the greater area of Leiden, the Netherlands, were eligible to participate in the NEO study. Participants were recruited via three recruitment strategies. First, participants were recruited by general practitioners in the area of Leiden, in the West of The Netherlands. Second, participants were recruited through advertisements in local newspapers and through posters distributed in public areas of Leiden and surroundings. Third, participants were recruited via the registries of three municipalities surrounding Leiden (Katwijk, Leiderdorp and Teylingen). Inhabitants of Katwijk and Teylingen aged between 45 and 65 years were invited to participate if they had a self-reported BMI of 27 kg/m2 or higher. All inhabitants aged between 45 and 65 years of Leiderdorp were invited to participate irrespective of their BMI, allowing for a reference distribution of BMI.
Participants were invited to a baseline visit at NEO study centre of the LUMC after an overnight fast. Prior to this study visit, participants collected their urine over 24 h and completed a general questionnaire at home to report demographic, lifestyle and clinical information. The participants were asked to bring all medication they were using to the study visit. At the baseline visit an extensive physical examination was performed, including measurements of anthropometry, blood pressure, both fasting and postprandial blood sampling (30 minutes and 2.5 hours after a liquid mixed meal), ECG, carotid artery IMT, and pulmonary function tests. In random subsets of participants MRI of abdominal fat, brain, knee, heart function, and pulse wave velocity of the aorta was performed, as well as indirect calorimetry, accelerometry combined with continuous heart rate, and total sleep time with actigraphy. Participants are followed via their general practitioners and hospital registries for the incidence of common diseases and mortality.
Study Overview
Detailed Description
Hypotheses
- Overweight and obesity affect major systemic responses, such as inflammation and coagulation that lead to the occurrence of major common diseases.
- The occurrence of these diseases is related to individual make-up, including genetics and fat type and location, and environment, and the interaction between the various systemic responses, and the (subclinical) disease outcomes.
Primary general objectives of the NEO study
- To study the pathways that lead to common diseases in overweight and obese individuals.
- To identify novel determinants of various diseases and conditions in overweight and obese individuals.
- To study interrelationships between diseases, newly identified determinants with each other and with classical, established risk factors.
Secondary general objectives of the NEO Study
- To identify novel determinants of various subclinical conditions in overweight and obese individuals.
- To develop novel methods for determining the risk of various diseases and conditions in asymptomatic overweight and obese individuals, in addition to established prognostic markers.
- To assess the burden of disease in a population-based cohort of overweight and obese individuals.
- To investigate the optimal diagnostic method to define overweight and obesity in terms of predicting various diseases.
