Analytical Epidemiology is part of the Epidemiology section of PSM. Practise 30 exam-style MCQs for NEET PG, FMGE, INI-CET and NEET SS, each with the correct answer and a detailed explanation.
Analytical Epidemiology MCQs focus on study design and its pitfalls — case-control versus cohort studies, selection bias such as Berksonian bias, and where hypothesis formulation and testing belong — high-yield NEET PG material for epidemiology.
Ans. is 'a' i.e., Selection bias Berksonian bias is a type of selection bias. Bias o It is any systemic error in the analysis of study that results in a mistaken estimate of an exposure's effect on the risk of disease. o Mainly biases are of following types.
Ans. is 'b' i.e., Measures incidence rate o Incidence rate can not be measured by case-control study as denominator (population at risk is not available).
ANALYSIS OF COHORT STUDY The data are analyzed in terms of : a.Incidence rates of outcome among exposed and non exposed, b.Estimation of risk. INCIDENCE RATES In a cohort study, we can determine incidence rates directly in those exposed and those not exposed. Estimation of risk Estimation of risk of outcome (e.g., disease or death) in the exposed and non-exposed cohorts is done in terms of two well-known indices: (a) relative risk, (b) attributable risk.
Formulation of hypothesis is associated with Descriptive epidemiology eg: doing survey in cross sectional study Testing of hypothesis is associated with Analytic epidemiology- eg Doing case control and cohort Reference: Park's Preventive and social medicine, 27th edition, Chapter Principles of Epidemiology & Epidemiology methods.
