        소화기 소증 분석과 사상체질 진단을 위한 사상소화기능검사(SDFI)의 타당화 연구

        채한,이정윤,이용재,Chae, Han,Lee, Jeongyun,Lee, Yong-jae 사상체질의학회 2021 사상체질의학회지 Vol.33 No.3

        Introduction The clinical usefulness of Sasang Digestive Function Inventory (SDFI) for analyzing Sasang type-specific pathophysiological symptom was illustrated repeatedly. It was revised to enhance its validity, reliability and clinical usefulness, however its clinical studies supporting these were not sufficient yet. Methods 193 healthy university students responded once to Nepean Dyspepsia Index-Korean (NDIK), Functional Dyspepsia-Related Quality of Life (FDQOL), and Dutch Eating Behavior Questionnaire (DEBQ), and twice to SDFI with four weeks of interval. The Body Mass Index (BMI) and Ponderal Index (PI) were also calculated. The 4-week test-retest reliability and correlation coefficients between NDIK, FDQOL, DEBQ, and SDFI were examined using Pearson's correlation. The significant differences between Sasang types in SDFI and its subscales were examined using ANCOVA with the age as covariate. Results The range of test-retest reliability for SDFI and its subscales was from 0.801 to 0.887. The SDFI-total correlated positively with BMI (r=0.323) and DEBQ-External Eating (r=0.433), while the SDFI-Digestion negatively with NDIK (r=-0.472) and FDQOL-total (r=-0.364). The SDFI-Habit correlated positively with BMI (r=0.310) and DEBQ-total (r=0.481), and the SDFI-Appetite with DEBQ-total (r=0.322). The SDFI-total, SDFI-Digestion, and SDFI-Habit scores of Tae-Eum type (35.6±6.25, 12.38±3.24 and 9.89±3.38, respectively) were significantly bigger than those of So-Eum type (29.84±8.31, 9.93±4.28 and 7.66±3.96). Discussion The SDFI was found to be an objective clinical measure with sufficient concurrent validity for measuring eating behavior and quality of life related to overeating and dyspepsia, and illustrated distinctive differences between Sasang types. It might be useful for the effective medical education and integrative medical practice.

        Biopsychological and pathophysiological features of Cold-Heat subgroup of Sasang typology with Sasang Digestive Function Inventory, Sasang Personality Questionnaire and Body Mass Index

        이미숙,Sang Yun Han,황민우,배나영,채한 한국한의학연구원 2018 Integrative Medicine Research Vol.7 No.1

        Background: The Sasang typology is a traditional Korean personalized medicine and its Cold-Heat subgroup identification is essential for effective use of medical herbs and acupuncture. The purpose of this study was to discover differences between Cold-Heat subgroups with objective clinical measures and to examine its clinical usefulness. Methods: The pathophysiological symptoms of the digestive system, temperament and body shape of 241 patients were measured using the Sasang Digestive Function Inventory (SDFI), Sasang Personality Questionnaire (SPQ) and Body Mass Index (BMI). The differences between Cold and Heat subgroups of each Sasang types were tested by Analysis of Covariance considering age and sex, while the associations of SDFI, SPQ and BMI with Cold-Heat subgroup were examined by logistic regression analysis. Results: There were significant differences between Cold and Heat subgroups in SDFI, SPQ and BMI for the So-Yang, SDFI and BMI for the Tae-Eum type and SDFI-Digestion subscale for the So-Eum type. Moreover, the SDFI-Digestion was a substantial predictor for Cold-Heat subgroup identification in three Sasang types. The logistic regression model with SDFI, SPQ and BMI correctly predicted 81.9%, 77% and 75.5% of the Cold-Heat subgroups in So-Yang, Tae-Eum and So-Eum types, respectively. Conclusion: The results of the present study showed that the objective and validated clinical measures of SDFI, SPQ and BMI would be useful for differentiating Cold-Heat subgroups of Sasang typology. Further clinical studies on pathophysiological mechanisms in Cold-Heat subgroup are required to generalize these results.

        과민성장증후군 환자의 사상체질별 소증 특성에 대한 연구

        김국화,이슬,박지은,채한,이정윤 사상체질의학회 2023 사상체질의학회지 Vol.35 No.2

        Objectives The aim of this study was to compare and analyze the difference in physical features, ordinary symptoms and clinical characteristics according to Sasang constitution of patients with irritable bowel syndrome who have visited a Korean medicine hospital. Methods We selected 45 patients with irritable bowel syndrome who have visited a Korean medicine hospital from April 20, 2015 to June 30, 2022. We retrospectively collected medical history and characteristics of subjects using data of Electronic Medical Record(EMR). Results Regarding BMI, Sasang Digestive Function Inventory-Total(SDFI-T), Sasang Digestive Function Inventory- eating Habit (SDFI-H) and heat sensitivity, Tae-Eum type was significantly higher than So-Yang and So-Eum types. In case of sweat score, Tae-Eum type was significantly higher than So-Eum type. As for the cold sensitivity, So-Yang and So-Eum types were significantly higher than Tae-Eum type. But there was no obvious difference among 3 groups in SDFI-Appetite (SDFI-A), SDFI-Digestion(SDFI-D), sleep, chest symptoms, Sasang Defecation Inventory(SDI), Sasang Urination Inventory(SUI) and HRV results. Conclusions BMI, SDFI-T, SDFI-H, cold-heat patterns and sweat could contribute to be used as clinical indicators to distinguish Tae-eum type from other constitutions(So-Yang and So-Eum types) in IBS patients. -

        사상소화기능검사의 개정 및 임상 타당화 연구

        이용재,이슬,김소형,이정윤,채한,Lee, Yong-jae,Lee, Seul,Kim, So-hyung,Lee, Jeongyun,Chae, Han 사상체질의학회 2021 사상체질의학회지 Vol.33 No.3

        Objectives The purpose of this study was to revise Sasang Digestive Function Inventory (SDFI) and improve its validity and reliability using clinical data. Methods The Sasang type and Cold-Heat pattern differentiation by certified clinical specialist and responses to SDFI items were acquired from 419 hospital patients. The revision of SDFI was performed using item analysis and Explorative Factor Analysis (EFA). Furthermore, the validity and reliability of the revised SDFI (rSDFI) were investigated using Confirmatory Factor Analysis (CFA), Internal Consistency and Item Response Theory (IRT). And, clinical significance of the rSDFI was examined for the differentiation of Sasang types and Cold-Heat patterns. Results The number of the SDFI items were modified from 21 to 15. And, the validity and reliability of the rSDFI subscale structure were found to be acceptable. The scores of rSDFI-total and rSDFI-E significantly decreased in the order of Tae-Eum (TE), So-Yang (SY), So-Eum (SE) types, and the rSDFI score of SE type was significantly lower than that of TE and SY types. The rSDFI-total score could differentiate Cold-Heat pattern in both SY and SE types. And the difference of digestive function between Cold and Heat pattern of SE type could be explained with the rSDFI-D score. The rSDFI-total score in Cold pattern significantly decreased in the order of TE, SY, and SE types, and the rSDFI-total score of TE type is significantly higher than that of SE type in Heat pattern. Conclusions Current results demonstrated the reliability, validity and clinical usefulness of the rSDFI in clinical patients. Therefore, rSDFI can be utilized as an objective clinical measure supporting the differential diagnosis of Sasang typology.
