Show moreOverweight 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. Show less

Show moreThe aim of this thesis was to unravel a selection of a multitude of potential causal pathways that may underlie the association between excess body fat and cardiovascular disease, such as adipokines, inflammation, HDL-cholesterol and postprandial triglyceride response, and cholesteryl ester transfer protein (CETP). We showed that hs-CRP and GlycA as measures of inflammation, adiponectin, and leptin are not associated with clinical and subclinical cardiovascular disease in the general population. However, all may be relevant markers of disease risk. Also, postprandial triglyceride excursions, genetically-determined CETP and HDL-cholesterol, while not related with subclinical atherosclerosis in the general population, may be interesting targets to pursue in women and men separately, and in subgroups of individuals at high-cardiovascular risk.
