Sleep quality scores among university students showed weak, non-significant correlations with cardiovascular risk domains including lifestyle (r=-0.055), blood pressure (r=0.022), and diet (r=0.127).

Does sleep quality correlate with cardiovascular risk factors in university students?
Sleep disturbance is common among university students but does not strongly correlate with other cardiovascular risk domains in this small cross-sectional study.
Background: Cardiovascular risk factors may begin to develop during young adulthood, when sleep habits, dietary behavior, stress exposure, and lifestyle patterns become established. Poor sleep quality has been linked with cardiometabolic risk, but evidence among university students remains limited. Objective: To assess the association between sleep quality and cardiovascular risk-factor domains among university students. Methods: A cross-sectional observational study was conducted among 235 university participants aged 18–26 years. Data were collected from April to June 2024 using a structured questionnaire, the Groningen Sleep Quality Scale, and a cardiovascular risk assessment questionnaire. Demographic characteristics, body mass index category, waist circumference category, sleep-quality responses, and cardiovascular risk domains were analyzed using IBM SPSS Statistics version 25. Frequencies and percentages were used for descriptive analysis, and Pearson correlation was used to assess relationships among nonconstant risk scores. Results: Most participants were female (63.4%) and aged 19–24 years (81.7%). Sleep-related complaints were frequent, including morning tiredness (64.3%), sleep latency longer than 30 minutes (61.3%), insufficient sleep (56.2%), nocturnal rising (53.2%), and sleep duration of five hours or less (51.5%). Sleep-related cardiovascular risk was categorized as medium in 64.3% and high in 11.9%. Sleep score showed weak correlations with lifestyle (r = -0.055, p = 0.404), blood pressure (r = 0.022, p = 0.739), and diet (r = 0.127, p = 0.051). The only statistically significant correlation was between blood-pressure and diet scores (r = 0.198, p = 0.002). Conclusion: Sleep disturbance was common among university students, but sleep score was not strongly associated with other cardiovascular risk domains. The findings support the need for larger studies using validated tools and adjusted analyses to clarify sleep-related cardiovascular risk in young adults
Ayub et al. (Mon,) conducted a cross-sectional in Cardiovascular risk factors (n=235). Sleep quality was evaluated on Correlation between sleep score and cardiovascular risk domains (lifestyle, blood pressure, diet). Sleep quality scores among university students showed weak, non-significant correlations with cardiovascular risk domains including lifestyle (r=-0.055), blood pressure (r=0.022), and diet (r=0.127).
