Suppose that the population attributable risk (%) of osteoporosis due to calcium deficiency has declined over the past decade. If it is known that the association between calcium intake and osteoperosis (i.e. the relative risk) has remained constant, what can you conclude? Why?
Expert Solution
Introduction
Population Attributable Risk (PAR) :
- The incidence of a disease in a population due to exposure that can be exposed or unexposed as a whole, is called Population Attributable Risk (PAR). It can be calculated as follows -
PAR = Incidence rate in total population - Incidence rate unexposed
- PAR data can be helpful in estimating the fraction of disease in the population under study that is attributable to the exposure.
