RELATIONSHIP ANALYSIS BETWEEN ORAL HEALTH CONDITIONS AND SIX FACTORS IN THE UNITED STATES
Dental health is an important aspect of one’s health and well-being (American Dental Association, 2015). This research analyzes six factors (income level, weather, sales tax, population density, dentist density, and water quality) to examine their relationship with oral health conditions based on 2015 state-level data in the United States. The results show that these factors indeed affect oral health conditions. The analysis results clearly show that income level, dentist density, temperature, and water quality have significant positive effects while temperature has a negative effect effects on oral health at state level.
Furthermore, this study uses a multilinear regression algorithm stepwise method to build three predictive models on different income groups, using the above factors to predict oral health. These models can be a helpful reference for further research in related areas, including but not limited to insurance companies, research institutes that work on improving public oral health, and government agencies.
