Sex differences in mortality in patients with acromegaly: a nationwide cohort study in Korea

Abstract

OBJECTIVE

The results of previous studies on sex differences in mortality and comorbidities among patients with acromegaly are diverse. We assessed the sex differences in mortality and the risk of complications in patients with acromegaly.

METHODS

We included 1884 patients with acromegaly with 1:50 age- and sex-matched 94200 controls using the Korean nationwide claims database from 2009 to 2019.

RESULTS

During the median 5.51 years of follow-up, the acromegaly group had higher all-cause mortality than the control group (hazard ratio [HR] 1.74, 95% CI 1.38-2.19), with higher risk in women than men (HR 2.17 vs. 1.36). The most common cause of death was malignancy. Women with acromegaly aged ≥50 years exhibited significantly higher mortality than men with acromegaly aged ≥50 years (HR 1.74 vs. 0.96). In a treatment subgroup other than surgery alone, women had a higher risk of mortality than men (HR 2.82 vs. 1.58). Sex differences in mortality among patients with acromegaly remained equal after adjustment for the Charlson Comorbidity Index, socioeconomic status, body mass index, alcohol consumption, smoking, fasting plasma glucose, creatinine, and total cholesterol. Patients with acromegaly had elevated risks of developing major adverse cardiovascular events, atrial fibrillation, obstructive sleep apnea (OSA), diabetes mellitus (DM), end-stage renal disease, Parkinson's disease, depression, and malignancy than age- and sex-matched controls, with a higher risk of OSA and DM in women than men.

CONCLUSIONS

The risk of mortality and complication in patients with acromegaly compared to age- and sex-matched controls were higher in women than in men.
