Body Mass Index (BMI) is calculated as measured weight in kilograms divided by measured height in metres squared.
Waist circumference is a convenient and simple measure, which is unrelated to height, correlates closely with BMI and the ratio of
waist-to-hip circumference, and is an approximate index of intraabdominal
fat mass and total body fat. Furthermore, changes in waist
circumference reflect changes in risk factors for cardiovascular disease
and other forms of chronic diseases, even though the risks seem to
vary in different populations. There is an increased risk of metabolic/
biometric complications for men with a waist circumference ≥102
cm (40 inches), and women with a waist circumference ≥88 cm
Fasting blood sugar
Fasting blood sugar is determined from a test for plasma glucose levels in a blood sample taken from an individual who has not eaten any foods or drinks other than water for at least eight hours. An accurate test can be obtained by using an approved blood glucose meter.
Serum cholesterol refers to the total level of cholesterol that is
found in the blood stream. Measuring the level of total cholesterol includes identifying all types or classes of cholesterol that are found in
the system. Laboratory test results may vary depending on age, gender,
health history, the method used for the test, and many other factors.
Blood pressure can be measured using a standard mercury sphygmomanometer or more easily with a blood pressure monitor or machine. Choose a machine that measures from the top of the arm, rather than the wrist or the finger. Finger monitors will not give accurate readings and wrist monitors are also less likely than upper arm monitors to give an accurate reading.
