The purpose of the present study was to analyze statistically correlations between socioeconomic factors and the prevalence of dental caries in developing countries. The DMFT index, which evaluates the incidence of dental caries, showed a positive correlation (P < 0.01) with several socioeconomic factors, such as life expectancy, adult literacy rate, school attendance rate, population employed in the service sector, population aged 15-64 years, and urban population. According to multiple regression analysis, population aged 15-64 years, population employed in the service sector, and urban population were the most influential independent socioeconomic variables, in descending order, with a regression coefficient of 0.635 and a coefficient of determination of 0.404 (P < 0.001). This finding suggests that the prevalence of dental caries in developing countries increases with the degree of urbanization.
本研究的目的是对发展中国家社会经济因素与龋齿患病率之间的相关性进行统计分析。评估龋齿发病率的DMFT指数与几个社会经济因素呈正相关（P < 0.01），如预期寿命、成人识字率、入学率、服务业就业人口、15 - 64岁人口以及城市人口。根据多元回归分析，15 - 64岁人口、服务业就业人口和城市人口是最具影响力的独立社会经济变量，影响力依次递减，回归系数为0.635，决定系数为0.404（P < 0.001）。这一发现表明，发展中国家龋齿患病率随城市化程度的提高而上升。
