Purpose
Hypopituitary patients have a reduced life expectancy owing to cardiovascular events. We investigated the prevalence of metabolic syndrome in hypopituitary patients for a follow-up period of at least 1 year in comparison with an age- and sex-matched nationwide control group.
Methods
A total of 515 patients with hypopituitarism who visited Seoul National University Hospital between January 2000 and December 2010 were included. Data for an age- and sex-matched control group were obtained from the Korean National Health and Nutrition Examination Surveys (KNHANES) (n = 1545). Metabolic syndrome was defined according to the modified National Cholesterol Education Program (NCEP-ATPIII).
Results
The prevalence of metabolic syndrome did not differ significantly between the hypopituitary and control groups for men (34.9 versus 30.3 %), but the risk of metabolic syndrome was higher in hypopituitary women than in controls (39.8 versus 28.5 %). In both sexes, the risks of central obesity and dyslipidemia were higher in the hypopituitary group than in the control group. Men had lower risks of hypertension and hyperglycemia in the hypopituitary group, which attenuated the risk of metabolic syndrome. Age greater than 40 years and obesity (BMI ≥25 kg/m2) contributed to a higher risk of metabolic syndrome.
Conclusions
The metabolic syndrome prevalence was higher in the hypopituitry group than in the control group in Korean women, and this was attributed to an increased risk of central obesity and dyslipidemia. Accordingly, early intervention to reduce metabolic syndrome needed in hypopituitary patients, i.e. women.
