Introduction:
It is known that emotional stress affects individuals with hypertension. Sleep quality is also associated with blood pressure regulation. In our study, we aimed to investigate the effect of Kahramanmaraş earthquakes on sleep quality in individuals with hypertension residing in Istanbul.
Method
This randomized and controlled study included hypertensive patients who visited the internal medicine outpatient clinic between March 7, 2023 and May 7, 2023. Individuals with hypertension consulted a psychiatrist for the presence of earthquake fear. The Pittsburg Sleep Quality Index (PSQI) was used to assess sleep quality.
Results
Seventy patients with hypertension aged 35–64 years, 35 with earthquake fear and 35 without, were included. While the mean PSQI sleep quality score of the group with earthquake fear was 7.26 ± 3.94, the mean score of the group without earthquake fear was 5.17 ± 3.89, which was higher (p = 0.013; p < 0.05). Based on the presence of earthquake fear, poor sleep quality was found in 71.4% (n = 25) of patients with earthquake fear and in 42.9% (n = 15) without, and a statistically significant difference was found (p = 0.016; p < 0 .05). The risk of impaired sleep quality in the earthquake-fear group was 3.333 times higher than that in the without earthquake-fear group (ODSS: 3.333; 95%CI 1.235–8.997).
Conclusion
Our study has shown that the sleep quality of individuals with hypertension residing in Istanbul is adversely affected by the fear of earthquakes. We believe that it may be useful to review the pharmacological treatments of individuals with hypertension whose sleep quality is impaired owing to the fear of earthquakes and provide close psychological support.
