Mål og innhald

To provide an overview of the various observational methods to study health and disease in populations, and enable students to use these methods in practical research.

Content:

The course addresses critical methodological aspects of observational epidemiological studies

  • Epidemiology - an overview
  • Sampling methods and design effects
  • Sample size and statistical power
  • Measures of disease occurrence and of exposure-disease association
  • Bias, confounding, effect modification
  • Surveys and surveillance.
  • Cross-sectional study
  • Cohort study
  • Case-control study

Points to remember in the planning and evaluation of the different study designs.

Læringsutbyte

On completion of the course the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge

The student:

  • knows about sampling methods and design effects
  • explains the methodological principles of study types in observational epidemiology (surveys and surveillance; cross-sectional study; cohort study; case-control study), and how these study designs differ from each other and from the design of randomized controlled trials

Skills

The student is able to

  • compare alternative sampling methods
  • calculate sample sizes for surveys, cohort studies, and matched and unmatched case control studies
  • calculate measures of disease occurrence and their precision and account for design effect in cluster sample surveys.
  • conduct simple analyses in STATA, such as estimating associations between exposures and outcomes, with adjustment for confounding factors
  • distinguish the principles of different observational study designs
  • evaluate selection- and information biases in these three study designs and discuss how to minimize such bias
  • evaluate confounding and interaction, how to differentiate between these, how to deal with these

General competence

The student is able to:

  • critically interpret published results from observational studies
  • critically interpret published results from observational studies
  • collaborate and contribute in groups across disciplines and decently present own work and comment constructively on peers¿ work

Krav til forkunnskapar

Proficiency in English at a level corresponding to TOEFL 79-93 or IELTS band 6.5 is expected.

Tilrådde forkunnskapar

Basic understanding in mathematics and epidemiology.

Studiepoengsreduksjon

5 ECTS credits to the course INTH956

Krav til studierett

Students enrolled in the master programme in Global Health, students enrolled in similar programmes at UiB or other partner universities (e.g. tropEd Network for Education in International Health).

Arbeids- og undervisningsformer

The pre-reading provides background information needed to follow the course. Each day has a mixture of lectures and practical sessions, with group work or individual work on specific assignments and the use of the computer laboratory for data analysis under supervision. The lectures are interactive, and course participants are encouraged to ask questions and discuss during all sessions. The reference literature is made available prior to the course through internet ("Mitt UiB"). Scientific papers will be handed out for reading, group work and presentations/discussions in plenary together with the course facilitators/lecturers. There will also be group work aimed at developing a draft protocol of an observational study.

Students investment time 125 hours: Lectures 40 hours, individual assignments or group assignments with supervision and discussions 40 hours and individual reading and lab exercises 45 hours.

Obligatorisk undervisningsaktivitet

In group work, seminars and exercises - 80% attendance. Contribution in group work is compulsory in order to take the exam.

Vurderingsformer

4-hour written exam consisting of short questions and problem-solving questions and calculations.

Students who receive the grade "F" are allowed to re-sit according to standard procedures at the University of Bergen.
