Screening for coronary risk factors in occupational health practice.

Abstract

Screening for coronary risk factors (blood cholesterol greater than 5.2 mmol/l; body mass index greater than 25; blood pressure greater than 140/90 and positive smoking history) using nurse administered voluntary health assessments was studied in occupational health practice. A high employee participation rate (80.9 per cent) was achieved with few employees declining to attend, confirming the advantages of workplace based screening. Hypercholesterolaemia, overweight and smoking were the most prevalent risk factors. Men had higher rates than women as judged by independent or concomitant risk factor rates; 56.5 per cent of men were over ideal body weight, 40 per cent of men smoked, 35.7 per cent of men had two risk factors and 2 per cent of men had four risk factors. Blood cholesterol and blood pressure were shown to increase with increasing body weight. It is suggested that body weight reduction and smoking cessation are the preferred intervention strategies in occupational health practice.
