- 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.

Abstract

- This study was conducted to evaluate the blood lead levels in 141 pregnant women who were not occupationally exposed to lead and their umbilical cord, arid to identify some differences in blood lead levels by living area. ; The subjects-were all delivered at St. Benedict Hospital in Pusan and the blood lead levels were measured by graphite furance atomic absorption spectrophotometer.
The summarized results were as follows.
1. The geometric mean lead levels in maternal and cord blood were 8.0+/-1.8microgram/dl, 5.0+/-0.6lmicrogram/dl respectively.
2. Lead levels in maternal (8.7+/-1.7microgram/dl) and cord blood(5.4+/-0.7microgram/dl) of industrial area(n=24) were higher than residential area(n= 124) which were 7.9+/-1.7microgram/dl and 5.0+/-0.6microgram/dl respectively (p<0.05).
3. Maternal blood lead concentration was significantly correlated to cord blood lead concentration (r=0.6090, p<0.001), but other variables (maternal age, paternal smoking, birth weight, etc) were not correlated.
