- Brief summaryRationale: With a rapidly ageing population it is essential to consolidate efforts to prevent disease from occurring in order to reduce the burden on the health care system and economy. Health Potential could contribute to this. Health Potential is a service that provides information on personal disease risks followed by lifestyle advice for 21 preventable common chronic diseases, based on an individual’s genetic background, lifestyle, medical history, occupational history and other characteristics. This information, which is delivered to the client in a face-to-face meeting, can be used to direct lifestyle decision making.

Objective: The primary objective is to study the effect of additional lifestyle counselling after receiving Health Potential on stage of behaviour change. The secondary study objective is to study the effect of additional lifestyle counselling after receiving Health Potential to change determinants of behaviour change. The hypothesis is that additional lifestyle counselling will lead to better lifestyle choices compared to no additional lifestyle counselling.

Study design: The full Leef!-study consists of two integrated designs: (1) a two-armed non- randomised controlled pre-test/post-test trial (part A), followed by (2) a two-armed randomised controlled pre-test/post-test trial among participants in the exposed condition of part A for whom consent is obtained (part B). This registration refers only to Leef!-study part B.

Study population: Clients of the Stofberg Groep purchasing Health Potential and the Stofberg Health Check (together named Personalised Health Check; PHC) who are willing to participate in part B.

Intervention: Four additional lifestyle counselling sessions at 0 weeks, 1 week, 4 weeks and 12 weeks.

Primary study parameters: The primary outcome parameter is stage of behaviour change.
