title: Prevalence of Comorbidity among People with Hypertension: The Korea National Health and Nutrition Examination Survey 2007-2013.
abstract: OBJECTIVE
  Joint National Committee guidelines attempt to vary treatment recommendations for patients based on considerations of their comorbidities. The aim of the present study is to estimate the age-standardized prevalence of common comorbidities among Korean hypertension patients.
  
  
  METHODS
  We analyzed the Korea National Health and Nutrition Examination Survey from 2007 to 2013. Among the 58423 participants, 30092 adults, aged ≥30 yrs who completed a health examination and interview survey, were selected. The survey procedures were used to estimate weighted prevalence and odds ratios for 8 comorbidities, including obesity, diabetes mellitus, dyslipidemia, cardiovascular disease, chronic kidney disease, and thyroid disease.
  
  
  RESULTS
  Most chronic conditions were more prevalent in adults with hypertension than in those without hypertension. Common comorbidities were obesity (60.1%), dyslipidemia (57.6%), and impaired fasting glucose (45.1%). Hypertensive patients with two or more comorbid diseases were 42.2% and those with three or more diseases were 17.7%. The age- and sex-specific prevalence of three or more comorbid diseases among male hypertension patients was significantly higher than those patients in the 30-59 (p<0.05) age group.
  
  
  CONCLUSIONS
  Comorbidity is highly prevalent in Korean patients with hypertension.
