title: Association between khat chewing and intestinal parasitic infestations: a community based, cross-sectional study done in Jimma Town, Southwest Ethiopia.
abstract: BACKGROUND
  Khat (Catha edulis Forsk), is the psychostimulant herb cultivated in East Africa. Khat chewing could have health damaging effect.
  
  
  OBJECTIVE
  The aim of the present study was to determine the association between khat chewing and intestinal parasitic infestation.
  
  
  METHODS
  A cross sectional study was conducted in Jimma Town in July 2010. Structured questionnaire was administered to 991 individuals selected by a systematic sampling method. Stool samples were collected for the diagnosis of intestinal parasitic infestation. Data analysis was done using SPSS Version 16.0 for Windows.
  
  
  RESULTS
  Among 991 respondents, 638 (64.4%) were females, 502 (50.7%) were Oromos, 486 (49%) were Orthodox and 475 (47.9%) of them were in the age group of 18-24 years old. The current prevalence of khat chewing was found to be 52.7%. The prevalence of single to multiple parasitic infestations was 33.4%. Negative association (p = 0.000) was recorded between the habit of khat chewing and intestinal parasitosis. Non-chewers were more affected than chewers.
  
  
  CONCLUSIONS
  Higher proportion of non chewers was infested with parasites than chewers, suggesting that khat chewing might have a protective role against parasitic infestation. Further investigation on the effect of khat extract in in vitro and in vivo is recommended to disclose detail mechanisms.
