Resumen:

the planning phase of research related to age and aging, the quality of knowledge derived from epidemiological studies, depends heavily on the solidity of the methodological design and the strategies for collecting data designed to answer the research question. Case?control studies are a cost-effective alternative for providing a valid and reasonably precise estimate for identifying an association force of a hypothetical relationship cause-effect in studies related to older adults population.Recently case?control studies have been related directly to cohort studies,which enabled researchers to design new patterns for their development while obtaining major benefi ts. The case?control study is the appropriate choice and at times the only alternative for studying diseases of very low incidence in older adults.With this type of study it is possible to explore a broad range of related exposures to illness. Another important advantage is that they require smaller samples and are less costly than experimental designs or cohort studies. Among the disadvantages or drawbacks of this type of study is that it can only provide information aboutthe event or target disease in the population that has been selected for carrying out the study. © Springer International Publishing Switzerland 2015.
