Health Promotion Projects on Physical Activity

An integrated community-based screening and secondary prevention program to promote physical activity among physically inactive individuals possessing risk factors of diabetes mellitus (DM) or being pre-diabetes (IGT/ IFG)


This proposed knowledge transfer project implemented an integrated screening and secondary diabetes prevention program basing on the experience of a previous RCT project. 1) It identified high risk individuals of age 45-69 years and living in participating public housing estates by using a 6-item short risk-assessment questionnaire; 2) all individuals possessing risk factors of diabetes were provided with some health promotion materials, and were invited to perform Oral Glucose Tolerance Test (OGTT) at a discount cost (HK$100 and market rate is HK$400); 3) sedentary (<150 mins of moderate/vigorous physical activity per week) pre-diabetes (IGT or IFG) identified by OGTT were then invited to participate in a free 6-month structured community-based, theory-based and support-group-based secondary prevention DM program; 4) in addition, those identified as high risk (possession of risk factors of DM) by the questionnaire but not joining our program for various reasons and willing to be contacted by us by phone, received brief intervention (sent SMS reminders and received a brief motivational interviewing (MI) of 15 minutes over the phone).

The 6-month intervention has three major components: 1) three meetings each with specific objectives (motivation and goal setting, reinforcement and maintenance), 2) feasible individual physical activity plans (prescription of physical activity), and 3) formation of support groups (each of size about 10) with those who are living in the same public housing estate for building up mutual support and facilitating group exercise such as group brisk walking.

All participants who received either the brief intervention or the 6-month intervention will be followed-up 6 months afterwards to see if there are any changes in their physical activity level and related cognitions.
