The results of a worksite health promotion programme in Kuala Lumpur, Malaysia.

The worksite is one of the key channels for the delivery of interventions to reduce chronic diseases among adult populations. It provides easy and regular access to a relatively stable population and it encourages sustained peer support. This paper reports a 2-year follow-up of the impact of a worksite health promotion programme on serum cholesterol and dietary changes among employees in a city in Malaysia. A quasi-experimental study was conducted among Malay-Muslim male security guards, with those working in a public university in Kuala Lumpur comprising the intervention group, and those working in the teaching hospital of the same university as the comparison group. They were comparable in socio-demographic characteristics. The intervention group received intensive individual and group counselling on diet, physical activity and quitting smoking. The comparison group was given minimal education on the same lifestyle changes through mail and group counselling. The intervention group showed a statistically significant reduction in their mean total cholesterol levels as compared with the comparison group, with an intervention effect of -0.38 (95% CI = -0.63, -0.14) mmol/l. The intervention group also reported a reduction in the amount of cigarettes smoked. The worksite was shown to be an effective channel for health promotion. The adoption of the new lifestyle behaviours should be supported and sustained through modification of work policies.
