Introduction: Obesity, excessive alcohol use, cigarette smoking, a lack of physical activity, stress, and an unhealthy diet are modifiable risk factors linked to hypertension. Non-modifiable risk factors for hypertension include older age and a family history of hypertension. The purpose of this study was to assess university students’ knowledge of hypertension risk factors. Methods: This was a cross-sectional study conducted at St. Augustine University of Tanzania. A pre-tested, semi-structured questionnaire was used to collect data. Out of a total score of eight, a score of four or more was considered good knowledge, and a score of less than four was considered poor. All sociodemographic characteristics were included in logistic regression to calculate the adjusted odds ratio. Results: A total of 390 undergraduate students participated in this study. Most of the participants 266 (68.2%) identified stress as a risk factor for hypertension. The median (IQR) knowledge score was 2 (2 - 3). Overall, only 43 (11.0%) of the participants had good knowledge of risk factors for hypertension. However, none of the sociodemographic factors were associated with a good level of knowledge of risk factors for hypertension. Conclusion: Our findings highlight poor knowledge of modifiable and non-modifiable risk factors for hypertension among university students in northwestern Tanzania. Only stress and older age were known by more than half of the students as risk factors for hypertension. To reduce the burden of hypertension, it is crucial for prevention and control programs to target improving university students’ knowledge of risk factors for hypertension.

Background: Sexual intercourse may be associated with serious complications and morbidities which may not be commonly experienced in clinical practice. One such complication is severe vaginal bleeding. Aim: To report a case series of postcoital vaginal lacerations in three women of various age groups with no prior surgical history who complained of acute onset, severe vaginal pain and bleeding after consensual intercourse. Case presentation: This case series describes the clinical features and management of women who required an examination under anaesthesia and surgical repair of vaginal injuries following consensual intercourse. The Post-operative recovery period was uneventful. Conclusion: A postcoital laceration is a rare emergency that may be complicated by excessive blood loss, which is increased if there is a delay in seeking care and or diagnosis. Prompt treatment should be instituted in such cases to minimise complications.
