Question

Explain how progress in genetics can help public health professionals stratify risk on the basis of biology, as contrasted with stratification of risk on the basis of exposure to environmental variables.

Answer 1

The genetic information which is available for normal and abnormal growth and development are driving important changes in health care.Genes are related to diseases in some or the other ways. Diseases such as diabetes, cardiac diseases are caused because of the issues with multiple genes in combination with life style and environmental factors.

The public health science is essential for interpreting the health significance of genetic variation. The environment or gene interactions at the core of biological phenomenon and most diseases are also based on public health sciences.

The genome sequence information should be linked with information about behaviours, nutrition, metabolism, diseases, medications, physical, chemical and microbial exposures from the environment in order to understand the genetic or environmental interactions which ultimately affects human health.
