Analysis on the difference between needs and recipients for scaling and its trend in Korea (2000-2009) / 대한구강보건학회지

ABSTRACT

OBJECTIVES: This study aimed to identify the trend regarding the difference between needs and recipients for scaling in the period from 2000 to 2009, and to analyze the differences by gender and age. METHODS: This study was a follow-up study that analyzed the secondary data. The analysis was done in those > or =19 years old who were included in the data obtained from KNOHS (2000, 2003), KNHANES, and CHS (2008, 2009). The dependent variables were needs and recipients for scaling, and the rate of the difference. Independent variables were the year, gender, and age. By performing the gender-age specific directly standardized the rates, independent t-test and one-way ANOVA. For statistical analysis, the study used MS Office Excel 2010 and PASW statistics 18.0. RESULTS: The rate regarding the needs for scaling has been steadily decreased, but the rate of recipients for scaling was increased, since 2000. The difference rate was reduced from 85.6% in 2000 down to 62.3% in 2009. Men showed a higher rate of needs for scaling compared to women (P or =55 years old) groups with preference, when setting the priority to mitigate the unmet needs for scaling.
