GECCO (GeoHealth Cohort Consortium)

The overall aim of GECCO is to enrich individual-level data of 20 renowned and on-going large scale Dutch cohort studies with a wide variety of environmental-level data. Providing centralised information of meta-data and streamlining access should ultimately enable a wide variety of research approaches on environmental determinants of lifestyle behaviours and chronic disease risk. The stepwise approach to implement this facility is: 1) Gather, combine and complement existing geographic information system (GIS) data in a repository, building on earlier efforts; 2) Enrich collaborating longstanding and renowned Dutch cohorts with these GIS data by secure and local linkages; and 3) Develop an easily accessible web-portal that facilitates collaborators to use the data by informing them about the cohort and GIS meta-data, and streamline data access procedures

SUPREME NUDGE (SUstainable PREvention of cardioMEtabolic risk through NUDGing hEalth behaviors)

SUPREME NUDGE is a 5-year project financed by the Dutch Heart Foundation and ZonMw, a Dutch national funding body for medical and health-care related research. With SUPREME NUDGE we expand a previous successful Dutch supermarket pricing strategy intervention, and incorporate promising elements such as nudging and ICT applications to provide real-time and context-specific physical activity feedback.

Targeting the environment in which health behaviour choices are made in can reduce cardiometabolic risk. Supermarkets form one of the most important point-of-choice settings with the potential to directly influence purchasing behaviors. ‘Nudges’ (small environmental encouragements) target the quick, automatic choices and do not require conscious decision making, and pricing strategies can seduce consumers to buy healthier alternatives. Such environmental cues can make it easier to initiate and maintain a healthy lifestyle, and as such, to improve cardiometabolic health. In addition, the use of theory-based mobile applications is an effective way to provide tailored and context-specific feedback on physical activity behaviors through the stimulation of ‘goal setting’ and ‘self-management’.

We will investigate the effects of this approach on dietary behaviours, physical activity and established cardiometabolic risk factors in adults with a lower SES. Using principles from Participatory Action Research and systems thinking, we will consult with the relevant stakeholders to explore options for upscaling and further implementation in society. Outcomes will provide policy- and practice relevant evidence with clear, stepwise and realistic leverage points for helping individuals to maintain healthy behaviors and improve their cardiometabolic health by making the healthy choice the easy choice.

PEN (Policy Evaluation Network)

PEN focuses on public policies addressing health-related behaviours in Europe. With PEN we aim to evaluate policy measures to promote a healthy diet and physical activity of the population in terms of their content, implementation and effectiveness. The project started on 1st February 2019 as part of the Joint Programming Initiative on a Healthy Diet for a Healthy Life (JPI HDHL). It will run for 3 years until end of January 2022.

SPOTLIGHT (Sustainable prevention of obesity through integrated strategies)

SPOTLIGHT is a European Commission funded research project that started in 2011. A systems approach was adopted across several independent but inter-related work packages. This was done by identifying mediators of successful outcomes in individual-level obesity interventions, by reviewing the state of evidence on social and physical environmental factors related to obesity, and evaluating the reach, effectiveness, adoption, implementation and maintenance (RE-AIM) of multi-level interventions reported on in the scientific literature, but also of multilevel initiatives that lacked a theoretical basis and were not conducted as part of scientific research. We also conducted qualitative analyses of enhancing and impeding factors relating to these multi-level interventions. Outcomes of work packages were used to inform the design of a cross-European survey and a virtual neighbourhood audit, aimed to gain understanding of the ways in which diverse factors influence the weight status of individuals, underlying obesogenic behaviours, and the social and physical environmental contexts in which they take place, within a cross-European perspective.

ENDEAVOR (Environmental determinants of lifestyle behaviors and risk of type 2 diabetes and cardiovascular diseases)

This project further builds on the New Hoorn Study and the Diabetes Care System. Information on the built environment of participants will be added using geographic information systems (GIS), in order to comprehensively examine determinants of lifestyle behaviours and diabetes risk, depression and cardiovascular disease.

Upstream determinants of lifestyle Behaviours and blood quality

In this project we are collaborating with Sanquin Donor Studies, and focus on environmental determinants of lifestyle behaviours and their effects on blood parameters.

DEDIPAC (Determinants of diet and physical activity)

DEDIPAC is a Knowledge Hub; a multidisciplinary consortium of scientists with currently nearly 300 researchers from 68 research centres in 12 countries across Europe. The objective of the DEDIPAC KH is "to understand the determinants, at both the individual and group levels, regarding dietary, physical activity and sedentary behaviours using a broad multidisciplinary approach, including biological, ecological, psychological, sociological, economic and other socio-economic perspectives and their interrelationships, and to translate this knowledge into a more effective promotion of a healthy diet and physical activity."

The work in DEDIPAC is divided into three Thematic Areas (TAs): TA 1: Assessment and harmonisation of methods for future research, surveillance and monitoring, and evaluation of interventions and policies

TA 2: Determinants of dietary, physical activity and sedentary behaviours across the life course and in vulnerable groups; TA 3: Evaluation and benchmarking of public health and policy interventions aimed at improving dietary, physical activity and sedentary behaviours.

NAD - Environment and effect on lifestyle in deprived neighbourhoods

Although many environmental change interventions are being implemented in the Netherlands, it is unknown what kind of barriers and facilitating factors are associated with successful adoption of these interventions. With this project -which has been completed recently- we aimed aimed to determine success and failure factors for implementation of environmental changes to improve physical activity and healthy eating in residents of deprived neighbourhoods. In addition we aimed to explore the perspectives of these residents: How they used their direct environment with regard to physical activity and dietary behaviour, and what environmental changes were required to improve these behaviours.

The Hoorn Prevention Study: Efforts to prevent diabetes type 2 and cardiovascular diseases in primary care

This randomised controlled trial was designed to investigate the effectiveness of a lifestyle intervention aimed at changing lifestyle behaviours and reducing the estimated risk of developing T2DM or a fatal CVD in at-risk adults. The background, methods and results of the Hoorn Prevention Study can be found under publications.
