Abstract
Increased resting metabolic rate (RMR), representing augmented energy expenditure, is a preferred physical characteristic; however, the Tae-Eum Sasang type, with a high incidence of obesity and metabolic diseases, has a higher RMR. This study scrutinized the physical characteristics of Sasang typology, a traditional Korean personalized medicine, to resolve this discrepancy, which can unravel the mechanism of Tae-Eum-type-specific obesity and improve the Tae-Eum Sasang-type diagnosis. A total of 395 healthy participants provided Sasang-type diagnosis using Sasang Constitutional Analysis Tool and physical features, including skeletal muscle mass, body fat mass, and RMR, along with those standardized using body weight. The Tae-Eum-type group showed significantly higher body weight, body mass index, body fat mass, and unstandardized RMR (kcal/day) than others, while their standardized measures of RMR per weigh (RMRw, kcal/day/kg) and percent skeletal muscle (PSM, %) were significantly lower. The logistic regression model revealed that the RMRw is pivotal for discriminating Tae-Eum type from others and explaining the developmental mechanism of Tae-Eum-type obesity. The aforementioned might provide a theoretical framework for Sasang-type diagnosis and Sasang-type-specific health promotion using bodily exercise and medical herbs.

Abstract
Sasang constitutional medicine emphasizes personalized disease prevention and treatment and has been used in various fields. Nevertheless, more efforts are required to improve the validity and reliability of the Sasang analysis tools. Hence, this study aimed to (1) identify key constructs and measurement items of the Sasang constitution questionnaire that characterize different Sasang constitutions and (2) investigate the similarities and differences in pathophysiological and personality traits between Sasang constitutions. The results of the Sasang constitution questionnaire were analyzed using multiple machine learning-based approaches, including feature selection, hierarchical clustering analysis, and multiple correspondence analysis. The selected 47 key measurement items were clustered into six groups based on the similarity measures. The findings of this study are expected to be beneficial for future research on the development of more robust and reliable Sasang conservation questionnaires, allowing Sasang constitutional medicine to be more widely implemented in various sectors.

Abstract
Introduction The Sasang type-specific pathophysiological symptom is pivotal for the Sasang type classification and pattern identification. The Sasang Urination and Defecation Inventory (SUDI) for urinary function analysis was developed; however, the clinical usefulness of urination-related subscales of SUDI in the Sasang type and Cold-Heat subgroup was not reported with acceptable validation analysis. Methods The clinical diagnosis of the Sasang type and Cold-Heat subgroup, responses to SUDI items, and weight and height of the 350 hospital patients were acquired retrospectively. The Sasang Urination Inventory (SUI) with SUI-CHR (problematic physical characteristics of urine), SUI-HSS (hypersensitivity of urinary urgency and high frequency), and SUI-DIS (urinary discomfort of hesitancy and residual urine sense) subscales using 12 items of SUDI were improvised. The item and construct validity of the SUI were examined using item response theory and confirmatory factor analysis, and the clinical usefulness of the SUI in Sasang type and Cold-Heat subgroup differentiation was attested. Results The SUI and its subscales showed acceptable structural validity and have clinical usefulness in the Tae-Eum type. The Tae-Eum type has a significantly higher SUI-CHR score than did the So-Yang type, and the Heat subgroup has a significantly higher SUI-HSS score than did the Cold subgroup in the Tae-Eum type. Discussion. The distinctive Sasang type- and Cold-Heat subscale-specific pathological symptoms in urinary function were revealed using the SUI. The SUI combined with objective Sasang typology measures might be useful for integrative precision medicine combining Eastern and Western practice and for evidence-based clinical education for medical professions.

Abstract
While stress is known to cause many diseases, there is no established method to determine individuals vulnerable to stress. Sasang typology categorizes humans into four Sasang types (So-Eum, Tae-Eum, So-Yang, and Tae-Yang), which have unique pathophysiologies because of their differential susceptibilities to specific stimuli, including stress. The purpose of this study was to determine if Sasang typology can be used identify individuals who are vulnerable to stress by evaluation of heart rate variability (HRV).This was a cross-sectional study. A total of 399 healthy men and women aged 30 to 49 years were recruited. Physical examinations for stress included HRV measurement and blood tests. The subjects also completed questionnaires about psychological stress, self-awareness, and lifestyle. HRV was analyzed using frequency-domain analysis. Subjects were divided into So-Eum (SE) and non-So-Eum (non-SE) groups according to their diagnosis.The weight and body mass index in the SE group were significantly lower than those in the non-SE group (both, P = .000). There were no significant between-group differences in any other demographic variables. In HRV analysis, the normalized high frequency (nHF) was higher (P = .008) while the normalized low frequency (nLF; P = .008) and LF:HF ratio (LF/HF; P = .002) were lower in the SE group than in the non-SE group.Although there was no difference in variables affecting HRV, HRV values were significantly different between groups. The LF/HF value for the SE group was at the lower limit of the normal range, although there were no associated clinical problems. These findings suggest that individuals with the SE type are more susceptible to stress than those with the other types. Thus, middle-aged individuals who are vulnerable to stress can be identified using Sasang typology.

Abstract
Background The pathophysiological symptom of Sasang typology is essential for getting clinical diagnosis and analyzing treatment effects. The clinical index for examining urination and defecation related symptoms were developed and validated with established clinical measures. Methods Questionnaire items of six subscales of Sasang Urination and Defecation Inventory (SUDI) were developed based on previous systematic reviews, and its clinical validity was examined with clinical measures of Urogenital Distress Inventory-6 (UDI-6), Overactive Bladder Symptom Score (OBSS), and ROME 3 criteria for Irritable Bowel Syndrome (ROME3-IBS) and Functional Constipation (ROME3-FC) using 48 healthy participants. The internal consistency of six subscales of SUDI were examined with Cronbach alpha. The Pearson correlation was used to examine correlation between SUDI and Western clinical measures, and the ANOVA was adopted to investigate differences among Sasang type groups in clinical measures. Results The SUDI-UCHR (problematic characteristics of urine) and SUDI-ANMD (defecation anomaly discomfort) were found to represent unique concept of traditional Korean medicine, however SUDI-IRRB (irritability of bowel movement) and SUDI-FCON (functional constipation) were similar with functional gastrointestinal disease of western medicine. SUDI-URET (ability to retain urine), SUDI-UDIS (urinary discomfort) and SUDI-ANMD of So-Yang type (7.95 ± 2.16, 14.33 ± 2.01, and 13.10 ± 2.57) are significantly different from those of So-Eum type (9.94 ± 2.54, 12.18 ± 2.96, and 10.59 ± 3.47, respectively). Conclusion The pathophysiological symptoms of urination and defecation in Sasang typology were systematically scrutinized, and summarized into six subscales of SUDI in this study. The SUDI would be useful for analyzing clinical symptoms of Sasang typology along with integrative collaboration of traditional Korean and Western medicine.

Abstract
BACKGROUND The purpose of this study was to investigate differences in obesity factors according to Sasang constitutional types and quality of sleep among Korean female college students. METHODS Surveys using Sasang-types questionnaires(QSCCⅡ) and quality of sleep questionnaires(PSQI; Pittsburgh Sleep Quality Index) were conducted with 339 Korean female college students. Additionally, obesity factors, including weight, fat mass, fat percent, abdominal fat percent, body mass index (BMI) and obesity rates were measured. All data analyses were performed using one-way ANOVA and two-way ANOVA. RESULTS The interaction between Sasang types and quality of sleep was presented in the quality of sleep status, subjective quality of sleep (domain 1), sleep duration (domain 3) and sleep disturbance (domain 5). Variables with interaction effects had significant differences in terms of obesity factors between groups with different quality of sleep according to the Sasang types. Moreover, significant differences in obesity factors between different Sasang types according to the quality of sleep were also observed. CONCLUSION This study characterized the reduction effect of improvement in quality of sleep on the fat mass of So-Yang type individuals and obesity factors in Tae-Eum type individuals. The results of this study will be used in improving sleep quality according to the Sasang types.

Abstract
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.

Abstract
BACKGROUND The purpose of the present study was to examine the body composition of So-Yang type males according to Sasang constitutional medicine, which is popular in Korea. Different Sasang constitutional types are associated with different muscle distributions, body shapes, and disease susceptibilities. We used the Sasang Personality Questionnaire (SPQ) as a measure of the temperament of each Sasang type. METHODS In total, 953 subjects aged over 20 years were recruited in Korea. We collected anthropometric parameters and bioimpedence information from the subjects and administered the SPQ. A logistic regression was conducted to calculate propensity scores. RESULTS The percentage of skeletal muscle mass in So-Yang (SY) and non-So-Yang (non-SY) males was 45.8 ± 2.7 and 44.2 ± 3.3, respectively, before matching and 45.8 ± 2.6 and 44.9 ± 3.0, respectively, after propensity score matching. The extracellular water (ECW)/intracellular water (ICW) and extracellular water (ECW)/total body water (TBW) ratios and SPQ scores were significantly different between the SY and non-SY types. CONCLUSIONS This study suggested that the SY type may be significantly and independently associated with body composition and could be associated with personality.

Abstract
The Sasang typology, traditional Korean personalized medicine, divides people into four Sasang types and suggests type-specific medical herbs and acupuncture for more safe and effective treatment. The main idea of Sasang typology seems relatively simple; however, the Sasang type diagnosis and type-specific treatment in clinical situation has been difficult for the clinicians and researchers. This study provided clinical procedures of type-specific Tae-Geuk Acupuncture (TGA) therapy along with basic understandings on Sasang typology and clinical indices for Sasang type differentiation. The TGA therapy would be useful for psychosomatic complaints and chronic pains by restoring the balance of Yin–Yang. The clinical application of TGA, its related biological mechanisms, and implications for further prospective clinical study were discussed.

Abstract
The purpose of this study was to review the pharmacognostic characteristics of Sasang type-specific medical herbs and suggest biological mechanisms that might be related to the personalized treatment of the East. Major compounds and their pharmacological activities of medical herbs for each Sasang types were systematically reviewed. The pharmacognostic characteristics of its main compounds were systematically analyzed with previous studies and three web-based databases. Sasang type-specific medical herbs were selected, and biological effects of their phytochemicals were reviewed from the pathophysiological features of each Sasang types. Phenolics were dominant in Tae-Yang type-specific herbs, iridoids and triterpenes with antipyretic and diuretic effects were in So-Yang type-specific, saponins (triterpene saponins and steroidal saponins) with antitussive effects were in Tae-Eum type-specific, and monoterpene and sesquiterpenes with stomachic effect were in So-Eum type-specific herbs. Pharmacognostic understandings on Sasang type-specific medical herbs with consideration of type-specific pathophysiological features were provided for the first time. This study would contribute to in-depth understandings on the pathophysiology of Sasang typology and integration of East-Asian and Western personalized medicine.

Abstract
Introduction. The purpose of this study was to examine the psychological structure of Yin-Yang based on the Sasang Personality Questionnaire (SPQ) in relation to Carver and White’s Behavior Inhibition/Behavior Activation System (BIS/BAS) Scale and Cloninger’s temperament model of the West. Methods. A total of 188 university students were classified as high (30%), middle (40%), and low (30%) groups based on their SPQ score and their differences in Cloninger’s temperaments and BIS/BAS subscales were analyzed using analysis of covariance after controlling the sex. Correlation among SPQ, Cloninger’s four temperaments and BIS/BAS subscales was also examined. Results. Significant differences in BAS (F = 11.703, p < .001), Novelty-Seeking (F = 4.945, p < .01), and Harm-Avoidance (F = 10.912, p < .001) were observed between high and low SPQ score groups after controlling for sex. The SPQ showed significant correlation with BAS (r = 0.303), Novelty-Seeking (r = 0.225), and Harm-Avoidance (r = − 0.273). However, BIS showed no significant differences between SPQ groups, and did not show correlation with the SPQ. Discussion. The current study demonstrated that Yin-Yang has similarities with and disparities from the Western tradition and may be examined with objective instruments. We showed that the emotionality of the East which is defined as mobility of emotion, not emotional instability as traditionally defined in Western theories, is pivotal for understanding the nature of emotion in the East. Suggestions are made for cross-cultural psychobiological study of the East and West.

Abstract
Previous studies on the Sasang typology have focused on the differential diagnosis of each Sasang type with type-specific pathophysiological symptoms (TSPS). The purpose of this study was to elucidate the latent physiological mechanism related to these clinical indicators. We searched six electronic databases for articles published from 1990 to 2015 using the Sasang typology-related keywords, and found and analyzed 35 such articles. The results were summarized into six TSPS categories: perspiration, temperature preference, sleep, defecation, urination, and susceptibility to stress. The Tae-Eum and So-Eum types showed contrasting features with TSPS, and the So-Yang type was in the middle. The Tae-Eum type has good digestive function, regular bowel movement and defecation, high sleep quality, and low susceptibility to stress and cold. The Tae-Eum type has relatively large volumes of sweat and feels fresh after sweating; however, the urine is highly concentrated. These clinical features might be related to the biopsychological traits of the Tae-Eum type, including a low trait anxiety level and high ponderal and body mass indices. This study used the autonomic reactivity hypothesis for explaining the pathophysiological predispositions in the Sasang typology. The Tae-Eum and So-Eum Sasang types have a low threshold in parasympathetic and sympathetic activation, respectively. This study provides a foundation for integrating traditional Korean personalized medicine and Western biomedicine.

Abstract
Background Functional dyspepsia (FD), which is a very common disorder worldwide, is known to be caused by multiple factors including environmental and genetic factors. Sasang constitutional medicine (SCM) is a component of traditional Korean medicine that emphasizes inherited characteristics of the physical and psychological patterns of a patient. This study investigated whether the prevalence of FD differs depending on Sasang classification. Methods A total 517 subjects (190 males and 327 females) were recruited, and interviewed for the presence of FD using a Rome III-based questionnaire. The Sasang constitution of all subjects were diagnosed using a Sasang constitutional analytical tool (SCAT). A Chi-square test was performed to compare prevalence of DF among different Sasang constitutional types. Results Of the 517 subjects, 115 (22.2 %) met the diagnostic criteria for FD, and the prevalence was significantly higher in females (26.9 %) than males (14.2 %, p < 0.01). The Sasang-constitution-based prevalence among all subjects was 27.5 % for Taeumin, 23.1 % for Soumin, and 16.4 % for Soyangin (p = 0.055). When compared by sex, the prevalence of FD among Sasang types showed significantly different patterns between males and females (p < 0.05); in females with FD, Taeumin predominated (32.5 % compared with 29.5 % and 18.8 % for Soumin and Soyangin, respectively; p < 0.05), whereas males with FD displayed a higher prevalence of Soumin (17.3 % compared with 9.1 % and 11.3 % for Taeumin and Soyangin, respectively; p > 0.05). Conclusions This study identified significant differences in FD prevalence depending on Sasang constitution and sex. Our findings provide data to guide future research on the prevention and management of FD.

Abstract
INTRODUCTION We examined the best-fit index for describing the constitutional or physical characteristics of Sasang typology for its universal application. METHODS Ponderal index (PI), body mass index (BMI), and basal metabolic rate (BMR) of the nationwide participants (n = 1663; age, 31-60 years) were calculated. We described and analyzed the usefulness of each index for maximizing the differences between Sasang types across age and sex using box plots, Pearson's correlation, and analysis of variance. RESULTS We found that the So-Eum, So-Yang, and Tae-Eum Sasang types were significantly (p < 0.001) different from each other in terms of PI, BMI, and BMR by the World Health Organization with weight (BMR-WHOw). The BMI was significantly correlated with PI (r = 0.933) and BMR-WHOw (r = 0.577). DISCUSSION AND CONCLUSION These study results show that PI, BMR, and BMI have their own clinical values, and could contribute to the study of the pathophysiological mechanism underlying the Sasang typology as the hypothalamus hypothesis.

Abstract
Background The purpose of present study was to examine biological and psychological characteristics of people according to the Sasang typology, which is popular in Korea. We evaluated the Sasang Personality Questionnaire (SPQ) as a measure of temperament, and Body Mass Index (BMI) as a measure of the somatic properties of each Sasang type. Methods Subjects were 2506 (877 males, 1629 females) outpatients between the ages of 20 through 70 who requested traditional medical assessment and treatment in Korea. The structural validity of the SPQ was examined and its correlation with BMI was analyzed. The SPQ and BMI measures of each Sasang type across age and gender were presented and their differences were analyzed with Analysis of Variance. Results Confirmatory factor analysis and path analysis identified an acceptable three-factor structure of the SPQ measuring differences in individual’s behavior, emotion, and cognition. SPQ scores (29.71 ± 1.00, 28.29 ± 0.19 and 26.14 ± 0.22) and BMI scores (22.92 ± 0.09, 25.56 ± 0.10 and 21.44 ± 0.10) were significantly (p < 0.001) different among So-Yang, Tae-Eum and So-Eum Sasang types, respectively. Conclusions The results showed that the SPQ and BMI is a reliable measure for quantifying the biopsychological characteristics of each types, and useful for guiding personalized and type-specific treatment with medical herbs and acupuncture.

Abstract
OBJECTIVES It has been hypothesized that Sasang constitutional types (SCTs) have a specific hypoactive organ, which can account for vulnerability to related diseases or symptoms. This study examined the relationship between SCTs and irritable bowel syndrome (IBS). DESIGN Cross-sectional study in a population-based cohort study in Korea. PARTICIPANTS 1362 individuals (705 men and 657 women) who participated in the Korean Genome and Epidemiology Study. OUTCOME MEASURES The participants were classified into SCTs by the integrated diagnostic model and asked about symptoms related to IBS using the Rome II criteria. RESULTS The prevalence of IBS differed significantly among the SCTs, with 33 (18.3%) of the So-eum (SE) type, 74 (9.9%) of the Tae-eum (TE) type, and 57 (13.2%) of the So-yang (SY) type having IBS. Even after adjustment for possible confounders, the SE type for both sexes continued to show 1.82-fold (95% confidence interval [CI], 1.05-3.16) excess odds of having IBS. Men with SE type had a 2.97 times (95% CI, 1.34-6.58) and a 2.50 times (95% CI, 1.15-5.47) significantly higher odds of having IBS than the TE and SY types, respectively. In analysis for the joint effect of SCT and psychological stress, the multivariate odds ratio of IBS was 3.21 (95% CI, 1.33-7.75) for the SE type and Psychological Well-Being Index-Short Form (PWI-SF) score (<27), and 5.83 (95% CI, 1.80-18.88) for the SE type and PWI-SF (≥27) compared with the TE type and PWI-SF score (<27). CONCLUSIONS The SE type of SCT is an independent risk factor for IBS. The findings support the hypothesis that persons with SE type are vulnerable to gastrointestinal diseases.

Abstract
Objective. This study was conducted for development and validation of the Sasang Digestive Function Inventory (SDFI) with type-specific digestive function-related symptoms for identification of Sasang type and pathological pattern. Methods and Materials. We selected questionnaire items for pathophysiological symptoms using internal consistency analysis and examined construct validity using 193 healthy participants. Test-retest reliability with a four-week interval as well as convergent validity was examined using the Nepean Dyspepsia Index-Korean (NDIK), Functional Dyspepsia-Related Quality of Life (FDQOL), Dutch Eating Behavior Questionnaire (DEBQ), and Body Mass Index (BMI). Results. The 21-item SDFI showed satisfactory internal consistency (Cronbach's alpha = 0.743) and test-retest reliability (r = 0.886, P < 0.001). Three extracted subscales, SDFI-Digestion, SDFI-Appetite, and SDFI-Eating pattern, explained 56.02% of the total variance. The SDFI showed significant (P < 0.001) correlation with total symptom score of NDIK, FDRQOL-Eating status, DEBQ-External Eating scale, and BMI. The SDFI score of the Tae-Eum (50.62 ± 8.05) type was significantly (P < 0.001) larger than that of the So-Eum (43.11 ± 11.26) type. Conclusion. Current results demonstrated the reliability and validity of the SDFI and its subscales, which can be utilized as an objective instrument for diagnosis of Sasang types and assessment of the type-specific digestive function.
