he aim of this study was to investigate the associations between objectively measured physical environmental neighbourhood factors and accelerometer-determined total sedentary time in adults.

This paper describes the study protocol to evaluate the effectiveness and cost-effectiveness of the EuroFIT program in supporting men to improve their level of physical activity and reduce sedentary behaviour over 12 months.

This article describes the barriers and facilitating factors to the adoption, implementation and continuation of the Dutch Obesity Intervention in Teenagers (DOiT) programme in the Netherlands.

This study investigates if and to what extent the Dutch Obesity Intervention in Teenagers (DOiT) program was implemented as intended and how this affected program effectiveness.

Interventions need to have a specific focus on sedentary behavior in order to generate clinically meaningful decreases in sedentary time.

My PhD thesis describes the preparation and evaluation of the adoption, implementation and continuation of the school-based Dutch Obesity Intervention in Teenagers (DOiT) programme.

The school-based Dutch Obesity Intervention in Teenagers (DOiT) programme is an evidence-based obesity prevention programme tailored to adolescents attending the first two years of prevocational education in the Netherlands.

In an ideal world, one combats public health problems with theory- and evidence-based programmes. In the real world, evidence-based programmes are often lacking and programmes that are developed and implemented are mainly practice-based.

The school-based Dutch Obesity Intervention in Teenagers (DOiT) programme is an evidence-based obesity prevention programme.

The aim of this study was to compare adiposity measures of 12- to 14-year-old Dutch adolescents attending lower levels of education in 2011 with adolescents measured in 2003.

The evidence-based Dutch Obesity Intervention in Teenagers (DOiT) programme is a school-based obesity prevention programme for 12- to 14-year-olds attending the first two years of prevocational education.

Adequate assessment of energy balance-related behaviours in adolescents is essential to develop and evaluate effective obesity prevention programmes.

This review aimed to systematically identify dietary, physical activity and sedentary behaviours in preschool children (4-6 years of age) that are prospectively related to overweight or obesity later in childhood.

This study aimed to (i) gain insight in the prevalence of overweight indices in European preschoolers (4-7 years); (ii) identify energy balance-related behaviours associated with overweight/obesity; and (iii) identify children at risk for overweight/obesity.
