Background
As a consequence of an aging workforce, workers need to prolong their working life. vitality is of great importance for the endured employability of aging workers. Since having high energy levels is one of the main components of vitality, lifestyle could contribute to aging workers’ vitality by positively affecting aging workers activity. As a consequence, a lifestyle intervention which aims to improve lifestyle is considered to be an effective instrument to keep aging workers vital. The aim of this study is to develop and evaluate a lifestyle intervention program to promote health in order to improve older workers’ (45 years and older) vitality.

Methods The intervention will be evaluated using a RCT design with 2 arms. The older workers in the intervention group (n=230) will be receiving tailored lifestyle intervention during 6 months. The older workers in the control group (n=230) will receive usual care. Measurement will take place at baseline and after 6 and 12 months after implementing the intervention. Primary outcome measures are vitality and lifestyle behaviour (physical activity, dietary behaviour, alcohol consumption, smoking habits). Secondary outcome measures are work engagement, productivity, general health status, quality of life, sick leave and cost-effectiveness.

Results
No results are available yet. This project will start January 2008 and the follow up measurements will continue until the end of 2010.
