Objectives The study aimed to investigate the prevalence and characteristics of headaches according to Sasang constitution among 5,764 participants residing in Ansung or Ansan in Korea.
Methods The Korea Sasang Constitutional Diagnostic Questionnaire was used to classify the constitution, and a self-administered questionnaire was used to collect headache data. The presence of headache, locations and patterns between groups were analyzed using the chi-square test and logistic regression adjusted for age, marital status, education, alcohol consumption, and smoking.
Results Results showed that 25.6% of participants had headaches, with a significantly higher prevalence in Soeumin (30.8%) compared to Soyangin (24.9%) and Taeeumin (24.3%). Soeumin had significantly higher odds ratios for headaches than Taeeumin in both crude (1.387) and adjusted (1.319) models. Headache sites showed high frequency in the order of occipital (8.1%), temporal (8.0%), forehead (5.4%), and global regions (5.4%), and Soeumin showed significantly higher odds ratios of forehead (crude: 1.616, adjusted: 1.543) and occipital pain (crude: 1.366 adjusted: 1.379) compared to Taeeumin.
No significant differences in headache patterns were observed among the groups.
Conclusions This study suggests that Soeumin has a higher prevalence of headaches, particularly in forehead and occipital regions, compared to other Sasang constitutions.
