Design And Implementation Of Health Risk Appraisal System Based On Panel Data

With the development of people's living standard, health and a long life have been two of the most important elements in the measurement of living quality. Researches show that many diseases have a bearing on human's bad habits and various factors in the environment. The removal and reduction of these causes via quantitative evaluations can surely control the diseases in advance. Consequently, a scientific maintenance and management system of health should be established for the quantitative analysis of people's health condition so as to improve the quality of their life.In this paper, the involvement, purpose, main methods and the present development of Health Risk Appraisal are analyzed, hence its necessity, and some requirements of the function of the system are putted on after a demand modeling study. In what follows, an overall design of the whole construction, function structure, disposal flow and database for the system is presented, as well as a detailed analysis of characteristics and a main model of the panel data. Besides, a fixed-effects model with variable intercepts is set up in this paper, an application of which is made to analyze the different levels of influences exerted by six risk factors (exercise, smoking, drinking, sleeping, overweight and mental pressure) on the diverse groups. Finally, the Health Risk Appraisal System is realized, and the system is tested at the end of this paper.It is demonstrated that Panel Data Model is an effective method for analyzing health risk appraisal while the Health Risk Appraisal an effective tool for measuring body conditions and providing correlative suggestions.Further researches with the help of this paper could be made on the more flexible selections of the panel data model according to the features of data being studied, for the system to evaluate people's health conditions more scientifically.
