[Relationship between obesity, total plasma cholesterol and blood pressure in male adults]

I investigated the relationship between the percentage of body fat, Body Mass Index (BMI) and total plasma cholesterol and blood pressure. The percentage of body fat was measured by the bioelectrical impedance method. The subjects investigated were 2,955 men aged from 23 to 59 years, who were working in a company making machinery. They were divided into four groups as follows. The normal group were within the normal BMI range (< 24) and body fat percentage range (< 20%). The seemingly obese group were over the normal BMI (> or = 24) and normal percentage of body fat range. The occult obesity group were within the normal BMI range and over the normal percentage of body fat range (> or = 20%). The obese group were over the BMI and percentage of body fat range. In each group, those who had high total plasma cholesterol and blood pressure were counted. The number of those who had high total plasma cholesterol was significantly larger in the obese group than in the seemingly obese group and the normal group, and larger in the occult obesity group than in the seemingly obese group and normal group and larger in the seemingly obese group than in the normal group. The number of those who had high systolic blood pressure was significantly larger in the obese group than in the occult obesity group, the seemingly obese group and the normal group, larger in the occult obesity group than in the normal group and larger in the seemingly obese group than in the normal group. The number of those who had high diastolic blood pressure was significantly larger in the obese group than in the occult obesity group, and the seemingly obese group and the normal group, larger in the occult obesity group than in the normal group, and larger in the seemingly obese group than in the normal group. These results suggest that measurement of percent body fat is useful in preventing adult diseases in employees with a high percentage of body fat, but who show no sign of abnormality in medical examinations, and those who are considered to be obese according to their BMI or percentage of body fat have a high risk of adult diseases.
