Introduction: Women constitute the majority of the global healthcare workforce-especially in nursing-yet remain under-represented in formal leadership roles. Understanding how gender disparities intersect with profession, age, and governance models is critical to advancing equity and strengthening nursing leadership within health systems.
Design: Cross-sectional ecological study across publicly funded healthcare entities in Catalonia, Spain.
Methods: Data from 124 entities were collected as of 31 December 2023 and analyzed by gender, profession (physician, nurse, or other), age group (≤ 55, > 55), and governance model (direct vs. indirect management) across five hierarchical leadership levels. Descriptive and inferential analyses were conducted to examine gender disparities in leadership distribution.
Results: A total of 8015 leadership positions were identified, of which 62.2% were held by women, despite women representing 75% of the workforce. A clear gender gradient emerged across leadership levels, with women's representation decreasing systematically at each step upward in the hierarchy. Women's representation declined significantly with increasing seniority, whereas men's representation increased at higher organizational levels. Among professions, male physicians were markedly represented at senior levels, while nurses-both women and men-were concentrated in lower and mid-level positions. Gender disparities were also shaped by age and governance model: younger women were clustered in frontline roles, and female leaders in indirectly managed entities were more evenly distributed across leadership levels than those in directly managed organizations.
Conclusion: Persistent gender disparities-particularly affecting nurses and younger professionals-highlight the need for inclusive leadership development, transparent promotion pathways, and robust gender-disaggregated data for workforce planning. Strengthening nursing leadership is not only a matter of equity but a strategic priority for building inclusive and responsive health systems.
