title: Functional Gastrointestinal Disorders in Young Military Men.
abstract: OBJECTIVE
  To estimate the prevalence and evaluate the associated psychological factors of functional gastrointestinal disorders (FGIDs) in males in their twenties who are currently enrolled in military service.
  
  
  METHODS
  A total of 1,073 men in the Korean army were asked to complete questionnaires based on the Rome III criteria and Symptom Checklist-90-revised (SCL-90R). The prevalence of FGIDs was estimated, and the associated psychological factors were evaluated.
  
  
  RESULTS
  A total of 967 men participated. The total prevalence of FGIDs was 18.5% (age-adjusted prevalence, 18.1%; 95% confidence interval [CI], 15.3% to 20.8%). The total SCL-90R scores were higher in men with FGIDs than men without FGIDs (24 [interquartile range, 13 to 44] vs. 13 [5 to 28], p<0.001) and higher in men with overlapping syndromes than in those with single FGIDs (31 [18 to 57] vs. 14 [5.75 to 29], p<0.001). Somatization (odds ratio [OR], 1.141; 95% CI, 1.09 to 1.20; p<0.001), obsessive-compulsive behaviors (OR, 1.084; 95% CI, 1.03 to 1.14; p=0.002) and depression (OR, 0.943; 95% CI, 0.90 to 0.99; p=0.020) were identified as independent predictive factors for FGIDs.
  
  
  CONCLUSIONS
  FGIDs are common among men in their twenties who are fulfilling their military duty. Somatization and obsessive-compulsive features from the tense atmosphere are associated with the development or progression of FGIDs. Patients who exhibit overlapping syndromes require greater attention given their more severe psychopathology.
