Gender differences in obesity hypoventilation syndrome

Area of Science:

• Pulmonary Medicine
• Sleep Medicine
• Endocrinology

Background:

• Sleep-disordered breathing (SDB) encompasses obstructive sleep apnea (OSA), central sleep apnea (CSA), and obesity hypoventilation syndrome (OHS).
• OHS is defined by obesity, daytime hypercapnia/hypoxemia, and SDB, excluding other hypoventilation causes.
• The role of gender in SDB, particularly OHS, remains under-explored, with diseases often under-recognized in women.

Approach:

• A literature review was conducted, identifying 490 references and ultimately analyzing 38 full-text papers meeting inclusion criteria.
• The review focused on understanding the impact of gender on the clinical presentation and treatment outcomes of SDB and OHS.
• Emphasis was placed on identifying knowledge gaps regarding OHS prevalence and risk factors in women.

Key Points:

• Women often experience diagnostic delays for SDB and OHS, leading to more advanced disease at diagnosis compared to men.
• The prevalence of OHS in women, especially postmenopausal women, requires further investigation.
• Gender-specific differences in OHS presentation and treatment response are not well-documented.

Conclusions:

• Enhanced clinical awareness of OHS in postmenopausal women may facilitate earlier diagnosis and more effective treatment.
• Further research is essential to determine OHS prevalence in women, the influence of menopause, and associated risks.
• Optimizing patient care for OHS necessitates a deeper understanding of gender-related factors.
