Individual Physical Activity Behaviour and Group Composition as Determinants of the Effectiveness of a Childhood Obesity Intervention Program.

Introduction: Up to now, there is limited clarity on factors that determine the effectiveness of childhood obesity interventions.

Objective: This study intends to uncover individual- and program-level predictors of BMI-SDS and fitness to achieve significant, sustainable health improvements.

Methods: Data of 249 children with obesity or overweight who participated in an outpatient multidisciplinary program were analysed and compared to 54 waitlist controls.

Organizational-level determinants of participation in workplace health promotion programs: a cross-company study.

Background: Attracted by the expected benefits such as reduced absenteeism and increased productivity, more and more firms decide to implement workplace health promotion programs (WHPPs). However, those programs can only be effective if employees actually participate. This study aims to (1) gain insight into the degree of enrolment rates in such programs across companies and (2) identify organizational level factors that are associated with employee participation.
