Brief Summary:

The main aim of this study is to measure the effectiveness of a worksite health promotion programme on improving physical activity behaviour and associated biological risk factors for cardiovascular disease among South African employees at increased risk for cardiovascular diseases. Additionally, the investigators will conduct an economic evaluation to determine the associated cost- effectiveness of these health related interventions offered at South African companies.

The investigators hypothesize that employees who receive the intervention counseling will have increased levels of physical activity and reduced risk for cardiovascular disease compared to those in the control group.

Primary Outcome Measures :
  1. Effectiveness of a worksite intervention on physical activity behavior [ Time Frame: 12 months ]
    The Global Physical Activity Questionnaire will be used for self reported levels of physical activity. Weekly time spent in moderate and vigorous activity will be reported.

Secondary Outcome Measures :
  1. Risk for cardiovascular disease [ Time Frame: 12 months ]
    The risk for cardiovascular disease will be based on blood pressure and cholesterol measurements, Body Mass Index, smoking status and dietary behavior

Ages Eligible for Study:   21 Years to 65 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

Employees identified to be at 'increased' or 'high' risk for CVD are eligible to take part in the research study. Risk status will be determined by using the (Euro) SCORE 12, together with their habitual physical activity levels, and Body Mass Index. SCORE incorporates age, total cholesterol, blood pressure and smoking status. This score ranks individuals according to their level of risk, ranging from very low to very high 10-year risk of fatal CVD (Appendix 1). Those with a risk of 5% or higher will be considered eligible.

Independent of the risk score, employees who are inactive (i.e., who do not comply with at least 30 minutes of moderate to vigorous activity on at least 5 days per week), or who smoke, and employees who are overweight (i.e., Body Mass Index ≥ 25 kg/m2) also will be eligible to take part in the study. Other inclusion criteria include being older than 18 years and having a contract with employer until end of 12-month measurement period

Exclusion Criteria:

  • Employees will be excluded for the following reasons: pregnancy, diagnosis or treatment of cancer, any other disorder that makes physical activity impossible. Contract workers whose employ with the company will end before the 12 month follow up measurement, will also be excluded from the study.
