OBJECTIVES: Obesity is a well-recognized risk factor for type 2 diabetes mellitus (DM) among young and middle-aged adults in South Korea. To elaborate on the association between obesity and Diabetes mellitus (DM), subjective data from self-reporting survey or objective data from health examination is generally used. This study was conducted to validate the change of association from using these different measurements. METHODS: Community Health Survey data and Korea National Health and Nutrition Examination Survey data, as subjective and objective data respectively, were used. Population, resident in Seoul and over 45 aged, were selected for the study and the association between obesity and DM were defined by using multivariate logistic regression model. RESULTS: In subjective data, DM prevalence was 12.4% (male, 14.7; female, 10.6) and obesity prevalence was 26.0% (male, 29.2; female, 23.4). Whereas, in objective data, DM prevalence was 15.0% (male, 17.8; female, 12.9), and obese population was 32.4% (male, 34.4; female, 30.8). Based on the effect of obesity on DM prevalence from each data, using objective data increased the impact of obesity. Difference of relative risk of obesity between from subjective data and from objective was bigger in female than male and statistically significant. CONCLUSIONS: The differences of association pattern between subjective and objective data were found, due to higher obesity prevalence in objective data, and discrepancies of socio-economic status. These discrepancies could be inevitable Therefore we have to face them proactively, and understand the different aspect of various variables from different measurement.

OBJECTIVE: To investigate whether the dual route model is applicable to Korean word reading in acquired dyslexia after stroke. METHOD: Sixty-two year old patient with dyslexia after left inferior temporal and occipital lobe infarct was evaluated according to the lexical processing. After evaluation of general cognitive and language function, visual perception, semantic, and lexical stages were assessed. RESULTS: Visual perception was appropriate, and semantic categorization and picture-word matching tasks were 80.6% and 78.6% correct, respectively. Lexical decision task showed no significant differences within word classes, except shorter reaction time in reading words of Korean origin than those of chinese origin (p <0.05). The patient was able to read only 39.8% of tested words, and he could not read all the non-words. Reading of high frequency word was superior (65.4%) to that of low frequency words (10.9%) and semantic errors were not remarkable (p <0.05). CONCLUSION: The patient showed characteristics of recovery from deep to phonologic dyslexia with impairment of grapheme to phoneme conversion (GPC) route. These findings support that dual route model is applicable to Korean word reading.
