Sustainability Consciousness, Green Advocacy, and Work Grit Among Nurses: Implications for Environmentally Sustainable Healthcare and Public Health

BACKGROUND: Healthcare systems contribute significantly to environmental pollution, energy consumption, and resource depletion, making sustainability an increasingly important environmental and public health priority. Nurses, as frontline healthcare professionals, play a critical role in promoting environmentally responsible practices and advocating for sustainable healthcare within clinical settings. OBJECTIVE: The study aimed to examine the associations between nurses' sustainability consciousness, green advocacy, and work grit in hospital settings. METHODS: A descriptive cross-sectional correlational study was conducted among 377 nurses working in two university-affiliated hospitals in Egypt. Data were collected using validated instruments assessing sustainability consciousness, green advocacy, and work grit. Descriptive statistics were calculated to summarize participant characteristics and study variables. Associations among sustainability consciousness, green advocacy, and work grit were examined using Pearson correlation analysis. Multiple linear regression analysis was conducted to identify significant predictors of green advocacy, while noting that the study design allows for identification of associations rather than causal relationships. RESULTS: < 0.01). Multiple linear regression analysis identified sustainability consciousness and work grit as significant predictors of green advocacy, explaining 34.2% of its variance. CONCLUSIONS: These findings highlight the interconnected roles of sustainability awareness, advocacy behaviors, and psychological resilience in promoting environmentally sustainable healthcare practices. Strengthening nurses' sustainability consciousness and work grit may enhance green advocacy and contribute to the development of sustainable healthcare systems, supporting global environmental and public health goals aligned with the United Nations Sustainable Development Goals.
