Document Summary
Exposure is identified (how active individuals are), disease is followed prospectively key feature of a cohort study ***prospective longitudinal in nature. Temporal sequence between exposure and outcome is clearly defined: exposure assessments are obtained before disease onset so the timing of the exposure un the natural history of the disease is in the correct sequence. Good at understanding multiple effects of a single exposure. Ie. within harvard alumni study- effects of pa were assessed on a number of different health outcomes stroke, hypertension, depression and first heart attack. Attrition loss to follow up ppl move, lose interest. Some disease outcomes are sufficiently rare that even a very large cohort many not produce enough cases to produce meaningful analyses. What makes a group of individuals different: often the group of individuals will have some disease, in which the case the question will be directed at the causes of their disease.
