Prevalence of some cardiovascular risk factors: obesity, hypertension, and smoking among medical students

Abstract

INTRODUCTION: Cardiovascular diseases (CVDs) are the principal cause of worldwide mortality, with 17.9 million deaths reported in 2019. In Saudi Arabia, CVDs account for 42% of all deaths, occurring on average 10 years earlier than in Western populations. Medical students are particularly susceptible to Cardiovascular disease CVD risk factors due to demanding academic schedules and lifestyle changes. This study aims to identify cardiovascular risk factors (CVRF) among medical students at King Faisal University, highlighting the need for preventive measures and curriculum modifications. METHODS: This prospective cross-sectional study was conducted from February to April 2024 at King Faisal University, focusing on undergraduate medical students. Participants not enrolled in the College of Medicine, those who declined to complete the survey, or those who submitted incomplete responses were excluded. A total of 313 students participated in the study. Data collection involved physical evaluations and a validated questionnaire covering demographics, medical history, lifestyle, and diet. Measurements included waist circumference, weight, height, blood pressure, and pulse. Data was analyzed using IBM SPSS Statistics version 19. RESULTS: Among participants, 52.4% had a normal body mass index BMI, while 19.5% were overweight and 11.2% obese. Blood pressure measurements showed 45.7% had normal BP, but 44.4% were prehypertensive. A family history of CVDs was reported by 55.6% of students, with hypertension (HTN) and diabetes being the most common. Smoking was infrequent, with only 5.1% reporting regular habits. Dietary analysis showed moderate consumption of unhealthy foods, with 80% maintaining a moderately healthy diet. Physical activity assessment indicated significant portions engaged in light or moderate activities, but only a minority met recommended levels for vigorous activities. Significant associations were found between physical activity levels and academic year, personal history of diseases, and smoking behavior. CONCLUSION: Most students had normal body weight, but many were overweight or pre-hypertensive. Family histories of CVDs, particularly (HTN) and diabetes, were common. Smoking was rare, but diets included frequent unhealthy foods. These findings underscore the need for targeted health programs to reduce cardiovascular risks in this population.
