Global Public Health Assignment: Epidemiology, Critical Appraisal

This assignment solution addresses key concepts in global public health, specifically focusing on epidemiology and critical appraisal. The first part defines epidemiology as the study of determinants and distributions of health outcomes and diseases, emphasizing the importance of study design in identifying biases and preventive measures. The second part explains critical appraisal as a method for evaluating research evidence, highlighting its role in selecting reliable research materials and promoting evidence-based practices. The solution provides clear definitions and explains the significance of each concept in the context of public health research and practice. References are provided to support the information presented.

Answer 1) Epidemiology is defined as the study of determinants and distributions of health
outcome and human diseases and also comprise of the methods that can be used to improve
the health condition of human being. A research article or journal can possibly include
epidemiology study design that will help the reader to identify or locate the source of
biasness, confounding factors and effect of modifications. In order to identify and study
diseases, the method of epidemiology study design is most widely used as it involves the
novel discipline and practices quantitative method of studying any disease that is affecting
the population and also inform the population regarding the control and preventive efforts
(Savitz and Westreich 2017). Hence, the concept of identifying the preventive measure of a
disease within the study population is the primary benefit of using epidemiology research
design that has attracted various readers and researchers conducting the study.
Answer 2) Critical appraisal is defined as the method of systematically and carefully
examining the research evidence that will help the reader’s and the researchers to identify the
relevance, value and trustworthiness of the research paper. Effective critical appraisals has a
positive impact on the future study of the researcher as the researcher will understand what
kind of journals should they select as the reference material that will help them to frame their
research in a proper and reliable way. The concept of critical appraisal will also assist the
researcher to use or practice and imply appropriate evidence-based research that is more
efficient and reliable, which will have a positive impact on their research and practice (Grove,
Gray and Faan 2019). Therefore, a researcher can use scientific evidence based information
to complete their research and practice.
