The purpose of this article is to present a system dynamic model for studying the interconnections between human weight and health problems which cause various problems throughout life.
The paper reviews key points about system thinking, its theories, and system dynamics. Models in the form of causal loops presenting the interconnections between weight factor and health problems are developed and discussed. Thereafter, a flow model of the problem is constructed and deaths caused by heart attack are studied under two situations of regular and taught cases. The paper identifies key health problems related to weight by using causal loops that demonstrate the whole picture of the situation.
With the aid of systems thinking and dynamic modeling researchers can study the impacts of weight on the generation of various health problems such as heart disease, high blood pressure, blood sugar, knee problems and more. This study shows that teaching people about their health will have a significant impact on the number of deaths related to heart attack.
With the model proposed here various studies can be carried out that relates weight to health issues. A sample situation is presented where deaths related to heart attack are simulated.
This article makes a significant contribution to the health study issues due to the fact that it shows how a factor such as weight can impact on hearth attacks, blood pressure, and blood sugar, to mention a few. To the best of the author's knowledge, this is the first study that relates weight to health problems using systems thinking concepts and system dynamic and it therefore make a significant contribution to the health literature.
