Abstract

OBJECTIVES
To describe the distributions of blood pressure level and risk group, and the current state of life style modification in the population of a large factory.
METHODS
We surveyed 1,088 workers in a large factory from June 2002 to August 2002. Information related to hypertension was collected through a questionnaire and medical examination. We classified the blood pressure level and risk group using JNC-VI criteria, and the current state of life style modification and medication according to the blood pressure level in the entire study population. REULTS: The prevalence of hypertension was 30.1% in all workers. The distribution of blood pressure level was 656 (60.3%) in normal stage, 160 (14.7%) in high normal stage, 190 (17.5%) in stage 1, 67 (6.1%) in stage 2, and 15 (1.4%) in stage 3. The numbers of workers in risk groups A, B and C were 296 (27.2%), 690 (63.4%) and 102 (9.4%), respectively. Among all workers, 432 (39.7%) needed to modify their lifestyle; 106 of whom (24.5%) needed to go on hypertensive drug medication. Overweight subjects were more common in stage 2 than in other stages (p=0.02). The numbers of smokers and low-exercisers were signigicantly lower in the higher blood pressure group than the lower blood pressure group (p<0.01). Alcoholic drinking was evenly distributed in all blood pressure level.
CONCLUSION
The prevalence of hypertension was 30.1% in all workers. The most common stage of blood pressure level was normal, followed by stage 1, high normal stage, stage 2, stage 3. The number of subjects in risk group B was more than that in the other risk groups. We recommend total worker education and the practice of lifestyle modification.
