In recent years, Hong Kong has been undergoing rapid changes with macro social and economic trends. The increasingly complex and diverse family structure contribute to concerns regarding the well-being of families in Hong Kong, including their health, happiness and harmony (FAMILY 3Hs). Family life and health education should be strengthened to meet the increasing needs of promoting healthy active lifestyle among Hong Kong families. In this connection, the FAMILY Project initiates the Fitter Families Project (FFP) with a focus on "FAMILY Holistic Health", will be conducted in order to increase the awareness of the importance of FAMILY 3Hs. FFP is a community-based research project with 3 main components - train-the-trainers programs, community-based family interventions and public education events. It is expected that trainees from the train-the-trainers programs will acquire adequate skills to organize community-based health education programs effectively. Participants of the community-based family interventions will gain knowledge on family holistic health and live a healthy active lifestyle. Attendees of the public education events will become more aware of the importance of FAMILY 3Hs.
