Nurses' Knowledge of Climate Change and Its Health Impacts in Southwestern Nigeria: A Mixed-Methods Study
This mixed-methods study of 396 nurses in Southwestern Nigeria reveals that while a majority possess good knowledge of climate change and its health impacts, significant gaps persist regarding indirect effects and institutional disparities, highlighting an urgent need to integrate climate-health education into formal nursing training and professional development programs.

Imagine the Earth as a giant, complex spaceship. For centuries, the crew (us) has been cruising along, but lately, the ship's life-support systems are acting up. The air is getting hotter, storms are hitting harder, and the water supply is getting murky. This isn't just about weather; it's about how these changes make the crew sick. Scientists call this "climate change," and they know it's a massive health threat. Now, think of nurses as the ship's primary medics. They are the first to see a patient with a fever, a broken bone, or a panic attack. If the ship's environment is getting dangerous, these medics need to know exactly how the environment is hurting the crew so they can treat them properly. But here's the big question: Are these medics actually trained to spot the link between a scorching heatwave and a sick patient, or are they flying blind? This study dives right into that cockpit to see what the nurses in Southwestern Nigeria know about the connection between a warming planet and human health.
The researchers decided to check the knowledge levels of 396 nurses working in six different hospitals in Ekiti State, Nigeria. They used a "mixed-methods" approach, which is like using both a ruler and a conversation to measure something. First, they gave everyone a quiz (the ruler) to see how many facts they knew. Then, they sat down and chatted with some of the nurses (the conversation) to hear their stories and understand where they learned what they know.
The results were a mix of good news and some gaps that need filling. About 61.4% of the nurses showed "good knowledge" of climate change and how it hurts health. They were sharp on the basics: they knew that climate change means long-term shifts in weather, that humans are the main cause (like burning fossil fuels and cutting down forests), and that it leads to more mosquito-borne diseases like malaria, water-borne illnesses like cholera, and even mental health struggles. They also correctly identified that air pollution hurts our lungs and that farming activities contribute to the problem.
However, the study found a few blind spots. When it came to indirect effects, the nurses were less sure. For instance, fewer than half correctly realized that climate change causes malnutrition and food shortages. It's like knowing that a storm will knock out the power, but forgetting that the power outage will also spoil the food in the fridge. The study suggests that this gap exists because the link between a changing climate and hunger isn't always taught clearly.
There was also a clear difference between the hospitals. Nurses working in big, tertiary hospitals (the major teaching centers) knew significantly more than those in secondary hospitals (smaller local facilities). It turns out that the nurses in the bigger hospitals were more likely to have good knowledge, while those in smaller facilities were more likely to have "poor knowledge." The study suggests this isn't because the nurses in smaller hospitals are less smart, but because they have fewer chances to attend training, workshops, or academic events where this new information is shared.
Perhaps the most interesting finding came from the conversations. When asked where they learned about climate change, most nurses didn't say, "My nursing school taught me." Instead, they said they learned it on their own, through social media, or by seeing it happen in their daily work. One nurse explained that they learned more from reading online and watching the weather change than from their formal training. This suggests that while nurses are curious and picking up the info, the official nursing curriculum and hospital training programs are currently missing the mark on teaching them how to handle a climate-changed world.
The authors are careful to say that while the nurses are doing a decent job, there is still work to be done. They don't claim that the problem is solved or that every nurse is an expert. Instead, they suggest that to truly protect patients in the future, nursing schools and hospitals need to start teaching climate health as a core part of the job, not just something you pick up from a tweet or a news article. If the ship's medics are going to keep the crew safe in a changing environment, they need a better manual.
