简要总结
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.
详细描述
Study Design:
"Working on Wellness - WOW" is a randomised controlled trial in South African worksites with a 12 month follow-up. Randomisation will take place at the company level, where participating companies will be assigned to either the intervention or the control group.
Study Population and Recruitment The study will be conducted in cooperation with a major national health insurer. Large companies (>300 employees) that are clients of this insurer, offering health and wellness days from August 2009 to February 2010 and that are based in Cape Town and Johannesburg will be approached to participate in this study.
Thereafter, over the course of two months all employees from these companies will be invited to participate in the wellness day(s) of their company. The invitation will take place as part of the feedback session at the wellness day and comprehensive information will be provided about the study. Employees agreeing to participate will be asked to sign an informed consent and to provide their email address and contact details. Participants will receive a small incentive at the start of the research study, and again upon completion.
Because all the companies hosting wellness days in this research study are clients of a major national health insurer, we will be able to access data for employees who do not volunteer for the screening activities. The data for the employees who choose not to participate will be sent to the researchers without any personal identifiers, thus ensuring employee confidentially. Being able to describe the non-responders is one of the strengths of this study design, and the insured population with whom we are working, providing insight into the problem of selection bias.

入选标准
- •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
排除标准
- •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.
