Question

estimates of risk are based on measuring the relationship between the presence of possible risk factors and _________.
environmental stresses
genetic inclination
subsequent incidence of particular conditions
demographic of the client

Explanation:

Risk estimates aim to determine how risk factors relate to the occurrence of specific conditions. Environmental stresses and genetic inclination are types of risk factors, not what they are measured against. Demographic of the client is a general characteristic and not directly what risk - factor relationships are measured against in terms of risk estimation. The key is to measure the relationship between risk factors and the subsequent incidence of particular conditions as this directly gives the risk (probability of a condition occurring given a risk factor).

Answer:

subsequent incidence of particular conditions
