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<.05). Those aged 55-64 and 65-74 years old demonstrated a higher rate of needs for scaling (P<.05), but actual recipients for scaling were largely populated in the age ranges of 25-34 years old and 35-44 years old (P<.05).
CONCLUSIONS
In the last 10 years, the difference between needs and recipients for scaling has been reduced. However, there were some differences depending on gender and age. To this end, it should be necessary to consider men and mid-to-old aged (> or =55 years old) groups with preference, when setting the priority to mitigate the unmet needs for scaling.
