Chewing Khat (Catha edulis) is a Risk Factor for Stroke: A Prospective Study

The plant known as Catha edulis, commonly referred to as Khat, holds significant cultural significance within the populations of East Africa and Southwestern Arabia. The objective of this study is to ascertain and assess the association between the act of chewing khat and the incidence of acute stroke.

The present study was carried out in a prospective observational manner at the Mogadishu-Somalia Turkish Training and Research Hospital. Data were gathered over a period of three years, from January 2021 to December 2023. The study encompassed all stroke patients who presented at the hospital's emergency department who had the habit of khat consumption and did not have previous risk factors of stroke. The study included a sample size of 52 patients.

The study involved 52 male patients who were diagnosed with acute stroke. Among the participants, 75% (n = 39) were aged between 18 and 39 years, while 25% (n = 13) were aged between 40 and 64 years. The findings indicate that hemorrhagic stroke was the prevailing stroke type, accounting for 88.5% (n = 46) of cases, while ischemic stroke accounted for only 11.5% (n = 6). All 52 participants in the study reported using khat. In addition to the act of chewing khat, it was found that 70% (n = 36) of the participants had been using khat for a period exceeding 5 years; none of the participants exhibited any additional risk factors for stroke.

The findings of our study indicate that Catha edulis, commonly known as khat, is a significant risk factor and potential causative agent for stroke. Khat consumption has been identified as a contributing factor to the incidence of cerebrovascular diseases.
