Type of Research Project
- Basic science
What is the background of the project?
Over the past 40 years, there has been a progressive increase in the prevalence of asthma and other allergic related diseases, particularly in developed countries and in urban areas of both developed and developing countries. The causes of these epidemiological trends are poorly understood and factors associated with the acquisition of a modern lifestyle, urbanization and migration appears to play a central role. In Latin America, a region that is already as urbanized (80%) as North America and Europe, it is expected that asthma prevalence could grow to epidemic levels over the coming decades. However, no studies have evaluated the impact of migration on asthma. The north areas of Ecuador present high rates of internal migration (36%). These locations are undergoing a rapid process of population change that includes urbanization, migration, economic development and adoption of a "modern" lifestyle.
What is the aim of the project?
To investigate the associations between prevalence of asthma and migratory history in children living in urban and rural areas in the Esmeraldas province - Ecuador.
What techniques and methods are used?
Cross sectional study based on secondary data from the SCAALA project “Social changes in Asthma and Atopy in Latin America” Stage 1. Literature review Search of scientific literature about the relationship between Migration and asthma in developing countries. Stage 2. Data analysis a) Estimate the prevalence of asthma and other allergic diseases in urban and rural populations of Esmeraldas - Ecuador. b). Describe the migratory patterns of urban and rural populations (place of birth and place of residence, age of migration, periods of time spent as a migrant, frequency of migration and place of birth of the parents) c) Associate the history of migration with the occurrence of asthma. Univariate analysis will be used to describe the migrations patterns. Multivariate analysis through of logistic regressions will be used to study the associations between migration and asthma. All analysis will be done with SPSS. Stage 3. Paper draft A scientific report containing the main findings of the study will be elaborate.
What is the role of the student?
- The student will observe the practical experiments but will be highly involved in the analysis of the results
- The tasks will be done under supervision
What are the tasks expected to be accomplished by the student?
1.The student is expected to help with the search of scientific literature using references management programs. 2. Database management using SPSS: Import and merging files, data cleaning, univariate analysis. 3. First draft of a scientific paper including introduction, methods and result, following the author guide of the chosen journal. 4. Work daily in a coordinated manner with the research team.
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- The student will prepare a scientific report - The student’s name will be mentioned in a future publication
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
Critical thinking and problem-solving Collaborative Agility and adaptability Database handling skill Subjects passed: Biostatistics, Epidemiology Previous experience with: SPSS, Stata, R
Are there any legal limitations in the student’s involvement
