[Statistical analysis of nutrients intake affecting serum lipid values of workers in an industry]

Relationships between serum lipid values and the quantity and quality of nutrient intakes of the employees in a steel factory were studied, and the following results were obtained. High density lipoprotein cholesterol (HDL-CL) and alpha-CL separated by electrophoresis in office workers were significantly lower than those of field workers and they were especially lower in cases of hypertriglyceridemia. HDL-CL, alpha-CL and Apo A values of workers with abnormal circulatory findings were demonstrated to drop down with increased cigarette smoking or carbohydrate intake. On the other hand, these values were apt to be elevated with increased alcohol or energy intake. beta-Lipoprotein and beta-CL separated by electrophoresis in workers with hyperlipidemia or abnormal electrocardiogram findings were shown to be at significantly high levels. Furthermore, beta-CL values in workers with abnormal circulatory findings were especially inclined to be elevated with increased cigarette smoking or fat intake.
