What are the two types of epidemiological studies and how are they classified?
a. Experimental and observational studies. Experimental studies are those in which the researcher studies the effects of exposure or absence of a certain factor, deciding which elements of the research will be exposed or not. Observational studies are those in which information is collected, and the experimental method is not used, as there is no intervention by the researcher, observations are made over time and allow the conclusion of the cause.
b. Experimental and descriptive studies. Experimental studies are those in which the researcher studies the effects of exposure or absence of a certain factor, deciding which elements of the research will be exposed or not. Descriptive studies describe a health situation or condition in relation to time, place, and individual, and can relate, for example, to the distribution of the disease in the population in relation to sex, age, location, or other characteristics.
c. Observational and descriptive studies. Observational studies are those in which information is collected, and the experimental method is not used, as there is no intervention by the researcher, observations are made over time and allow the conclusion of the cause. Descriptive studies describe a health situation or condition in relation to time, place, and individual, and can relate, for example, to the distribution of the disease in the population in relation to sex, age, location, or other characteristics.

A alternativa correta é a letra A: Estudos experimentais e observacionais. Estudos experimentais são aqueles em que o pesquisador estuda os efeitos da exposição ou ausência de um determinado fator, decidindo quais elementos da pesquisa serão expostos ou não. Estudos observacionais são aqueles em que as informações são coletadas, e o método experimental não é utilizado, pois não há intervenção do pesquisador, observações são feitas ao longo do tempo e permitem a conclusão da causa.
