Abstract

CONTEXT: Evidence on the long-term and general health of males with gynecomastia is lacking.

OBJECTIVES: To assess health before and following a diagnosis of gynecomastia.

METHODS: A register-based cohort study of 140 574 males, of which 23 429 were diagnosed with incident gynecomastia and age- and calendar-matched (1:5) to 117 145 males without gynecomastia from the background population. Males with gynecomastia were stratified into males without (idiopathic) or with a known preexisting risk factor (disease/medication). Cox and logistic regression models investigated associations of disease risk according to International Classification of Diseases 10th revision sections following and before gynecomastia diagnosis.

RESULTS: A total of 16 253 (69.4%) males in the cohort were identified with idiopathic gynecomastia. These males had a statistically significant higher risk of future disease across all included disease chapters (hazard ratio [HR], 1.19-1.89), with endocrine diseases representing the greatest disease risk (HR, 1.89; 95% CI, 1.76-2.03). The highest subchapter disease risk was observed for disorders of the endocrine glands (odds ratio [OR], 7.27; 95% CI, 6.19-8.54). Similarly, the ORs of comorbidities were higher across all included disease sections (OR, 1.05-1.51), except for psychiatric disease (OR, 0.72; 95% CI, 0.68-0.78), with the highest association with musculoskeletal/connective tissue (OR, 1.51; 95% CI, 1.46-1.57) and circulatory (OR, 1.36; 95% CI, 1.29-1.43) diseases.

CONCLUSIONS: The presence of idiopathic gynecomastia is an important first clinical symptom of an underlying disease and a significant predictor of future disease risk. These findings should stimulate more awareness among health care providers to increase identification of gynecomastia and its causes in males.
