Summary

Overweight and obesity are abnormal or excessive body fat accumulation that presents a risk to health. The World Health Organisation defines overweight and obesity with the Body Mass Index (BMI) classification, which is a measure of a person’s weight in kilograms (kg) divided by the square of height in meters (m2). Overweight is defined as a BMI of 25 kg/m2 or higher, whereas obesity is defined as a BMI of 30 kg/m2 or higher. It is estimated that one of every three individuals in the global population has overweight. The prevalence of obesity is increased threefold from 1975 to 2016, with a faster-growing pace in low- and middle-income countries than high-income countries. 

One common complication of obesity is the metabolic syndrome, which is defined as the co-occurrence of at least three out of five cardiometabolic abnormalities (abdominal obesity, hypertension, hyperglycaemia, hypertriglyceridemia, and low HDL-cholesterol). The metabolic syndrome is a strong risk factor for type 2 diabetes and cardiovascular diseases, and is considered a pathway from obesity to the cardiometabolic diseases occurrence. Thus, if metabolic syndrome or its components are identified and treated early, type 2 diabetes and cardiovascular diseases may be prevented. In this multi-ethnic global population, it is well-established that different ethnic populations have different cardiometabolic risks. Studies have shown that Asian populations develop cardiometabolic complications earlier at the same amount of adiposity as the Western populations.
