Document Summary
Risk factors in early life perinatal epidemiology. Focused on spread of disease in population. Can be: disease group specific (cancer, autism, methodology specific (genetic influence, exposure specific (pharmacoepidemiology, obesity, combo of others. Exposure predictors of things that you"re interested in. Confounder: common cause of both exposure and outcome, causes bias. Effect (measure: incidence, prevalence, risk ratio, rate ratio, odds ratio, hazards ratio, relative vs absolute risks. Prevalence: proportion in a population, prevalence of disease or exposure. Incidence: new cases, tells us change in status from non-disease to disase in a population at risk in given time frame. Chronic vs infectious disease epidemiology: infectious. Cases leave prev pool by recovery or death: chronic. Cause vs association: most studies are observational, randomization = balanced, observational studies, confounders = not balanced. Epidemiology can help us understand: prevalence, changes in disease burden w/in population, associations w/ autism and rare exposures. Epidemiology not great at: bio mechanisms.
