Abstract

This proposal consists of a research internship at the Imperial College under the supervision of Professor Christopher Millett at the Imperial College London from the Faculty of Medicine, School of Public Health. The objective of the research project is to evaluate the association of ultra-processed food consumption with the incidence of overweight and obesity in a UK cohort. The study comprises the analyses of data of individuals aged 40-69 years old from the UK Biobank, which is a prospective cohort. The survey included the collection of demographic and socioeconomic data, the directly measure of weight, height and waist circumference, and the evaluation of individual food intake. We will estimate the percentage of ultra-processed foods consumed relative to total energy intake. Separate Cox proportional hazards model will be used to estimate hazard ratios and associated 95% confidence intervals for each outcome. Potential covariates to be tested include individual's socio-demographic characteristics and physical activity. The internship at the Imperial College London will be relevant for the improvement of my postdoctoral project since their researchers have great tradition and experience in longitudinal analyses. The work plan goes from February to August 2019 and aims at training in longitudinal analyses, scientific writing, the participation in scientific events like seminars and the development of a manuscript for publication on a peer-reviewed journal.
