To determine the frequency of different blood groups among female medical students and to find the association of blood groups and body mass index with blood pressure.
This cross-sectional study was performed at the University Medical and Dental College, Faisalabad, Pakistan, from March to April 2016, and comprised female medical students. Participants were divided into groups on the basis of their ABO blood groups and on body mass index criteria. Blood groups were determined by simple conventional slide method. Blood pressure was estimated by manual auscultatory technique with a mercury sphygmomanometer. Data was analysed usingSPSS20.
There were 145 students with an overall mean age of18.4±0.75 years (range: 17-23 years). Blood group B was the predominant group 65(44.8%). Besides, 130(89.6%) subjects were rhesus positive and 23(53%) subjects of blood group O were pre-hypertensive. Multiple regression analysis indicated significant positive association of blood group O with both systolic and diastolic blood pressure (p=0.002, 0.001). However, subsequent logistic regression showed significant association only with diastolic blood pressure (p=0.001). Relative risk of pre-hypertension for obese (p=0.001) was greater than non-obese subjects. Body mass index was significantly associated with both systolic and diastolic blood pressure (p=0.004, 0.042).
Blood group B was the most common blood group. Blood group O was associated with diastolic pre-hypertension, while body mass index was associated with both systolic and diastolic pre-hypertension.
确定女医学生中不同血型的频率，并找出血型和体重指数与血压之间的关联。
本横断面研究于2016年3月至4月在巴基斯坦费萨拉巴德大学医学与牙科学院开展，研究对象为女医学生。参与者根据ABO血型和体重指数标准进行分组。血型通过简单的传统玻片法确定。血压采用汞柱式血压计通过手动听诊技术进行测量。数据使用SPSS 20进行分析。
共有145名学生，总体平均年龄为18.4±0.75岁（范围：17 - 23岁）。B型血是主要血型，有65人（44.8%）。此外，130人（89.6%）为Rh阳性，O型血的23名受试者（53%）处于高血压前期。多元回归分析表明，O型血与收缩压和舒张压均呈显著正相关（p = 0.002，0.001）。然而，随后的逻辑回归显示仅与舒张压有显著关联（p = 0.001）。肥胖者患高血压前期的相对风险（p = 0.001）高于非肥胖者。体重指数与收缩压和舒张压均显著相关（p = 0.004，0.042）。
B型血是最常见的血型。O型血与舒张期高血压前期相关，而体重指数与收缩期和舒张期高血压前期均相关。
