    Relationship of Body Mass Index with Blood Pressure Levels Among Sudanese Adults Living in Khartoum State
    (Medwell, 2020) Mazin S. Abdalla; Ibrahim A. Ali; Azza M. Bashir; Omer A. Musa
    The blood pressure (systolic and diastolic) has been found to increase with increased weight. This relationship is well advocated in many solid researches around the world. However, the relationship does not account to a cause and effect relation, the increment in the body weight may only raise the risk of increasing blood pressure. The objective of this study is to investigate the relationship between the body mass index and blood pressure levels in healthy Sudanese population residing in Khartoum state. A cross sectional study was conducted during July-August, 2016 in Khartoum state on a sample size of 200 subjects adult males/females of ages between 20-60 years and who were not known to be hypertensive. All the participants were assessed by a questionnaire covering age, gender, physical activity, daily salt intake and smoking history. Blood pressure was measured using the manual sphygmomanometer. Weight was measure using the standard scale. BMI was calculated according to the formula Weight (kg)/[height (m)]2. Correlations between the variables were estimated and p<0.05 was considered statistically significant. There is a significant positive relationship between the BMI and the systolic blood pressure (p = 0.01), the statistical analysis also showed a significant positive relationship between the BMI and the diastolic blood pressure (p = 0.01). This study has demonstrated that the association between the body mass index and the blood pressure is significant. However, further studies on a larger sample size is required, so as to establish a mathematical formula to predict the blood pressure given the body mass index. There is positive correlation between systolic, diastolic blood pressure and BMI. Increased blood pressure was seen in individuals with higher BMI when compared with individuals with lower BMI.
