This thesis aims to investigate the impacts of urbanization on human health, especially metabolic health and allergic disease, by incorporating many aspects of scientific investigation. Our cluster-randomized-controlled trial showed that, helminth infection, a characteristic feature of rural areas, and anthelmintic treatment, could significantly affect metabolic profiles and hormones. Thus, the ongoing deworming program in Indonesia require in parallel, monitoring of the metabolic health. Additionally, based on our prospective cohort study and analysis on a large scale nationally representative data, although Indonesian rural populations have relatively better metabolic profiles compared to urban, lifelong residence in rural areas does not protect their community members from adverse metabolic changes due to urbanization. Next, we observed that majority of individuals with diabetes in Indonesia were undiagnosed and untreated, especially in rural populations, which warrants extensive action plan from all related stakeholders. Lastly, high-dimensional data analyses on the systemic and nasal mucosal immune profiles revealed a stronger inflammatory immune responses in the nasal mucosal of Indonesian urban young adults with allergic rhinitis compared to their rural counterparts.

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
