How does the ""healthy worker effect"" influence the interpretation of findings from occupational health research? an epidemiologic researcher finds that mortality for assembly line workers in an automobile factory is slightly higher than the mortality of the general population. assume that the healthy worker effect is operative. would it tend to decrease or increase mortality differences between the workers and the general population?

The healthy worker effect in epidemiology is a type of bias that takes away from the validity of data. It helps reduce the death rate in employed individuals when compared to the general population.

The high amount in

Mortality rate for general population is a combination of working and nonworking people.

The healthy workers are often exposed to more work place hazard which could increases their death rate chances as seen in this example.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
