Why epidemiological triad has proven indiquate on non infectious disease, whit relevant APA reference?

The epidemiological triad is a model used in epidemiology to understand the factors that contribute to the occurrence and spread of infectious diseases. It consists of three components: the host, the agent, and the environment. However, this triad model is not always applicable to non-infectious diseases, as these diseases often have different etiologies and risk factors.

Non-infectious diseases, such as cardiovascular diseases, cancer, and diabetes, are typically caused by a combination of genetic, environmental, and lifestyle factors. These diseases do not involve the transmission of pathogens from one person to another, which is a key characteristic of infectious diseases.

One study that highlights the limitations of the epidemiological triad model for non-infectious diseases is by Rothman, K. J., Greenland, S., & Lash, T. L. (2008). Modern epidemiology. Lippincott Williams & Wilkins. In this comprehensive textbook on epidemiology, the authors discuss the limitations of the triad model when applied to non-infectious diseases. They emphasize the importance of considering multifactorial causation and the complex interplay of genetic and environmental factors in the development of these diseases.

In conclusion, the epidemiological triad model is not suitable for understanding non-infectious diseases due to their different etiologies and risk factors. The study by Rothman, Greenland, and Lash (2008) provides a comprehensive overview of the limitations of the triad model in the context of non-infectious diseases.
