Things I need to work on!!!! Flashcards
Do epidemolgicsts always take time into consideration when describing the frequency of disease?
YES, this always happens.
Why is the term dis-ease used instead of disease?
Because epidemiology is about all health related outcomes not just disease. An example would be stress, sleep deprivation, or depression.
What is reverse causality when does it occur the most?
Reverse causality is when you mistaken whether A causes B or if B causes A. This most occurs in cross-sectional studies because when you measuring the exposure and outcome at the same time, you don’t actually know which came first.
Define the terms observational study and experimental study.
Observational study is when you when you observe the study and don’t intervene. Examples would be ecological, cohort and cross-sectional. Experimental studies are studies where do you intervene like RCTs, or ecological.
What does a 95% response rate mean?
.A 95% response rate is typically considered excellent, as it means that the vast majority of eligible people who were invited to participate agreed to do so.
What are the main points of randomly allocation in RCTs?
In a well-conducted randomized controlled trial (RCT), participants are randomly assigned to either the exposure (brisk walking) or comparison (slow walking) group. The random allocation ensures that the two groups are similar at the start of the study in terms of various factors, such as age, health status, and lifestyle, which helps minimize bias and confounding.
