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.
