Khat Dependence, Use Patterns, and Health Consequences in Australia: An Exploratory Study

Area of Science:

• Public Health
• Substance Use Disorders
• Migrant Health

Background:

• Khat dependence and its health impacts are understudied in Australia.
• Quantitative data on khat use patterns and associated health problems are lacking, particularly within migrant communities.

Purpose of the Study:

• To describe khat dependence, use patterns, and related health problems in Australian migrant communities.
• To assess the association between khat dependence, use frequency, and psychological/physical health issues.

Main Methods:

• A 48-item questionnaire was administered to 52 self-reported khat users from African migrant communities in Australian cities.
• The Severity of Dependence Scale for khat use (SDS-khat) was used for screening.
• Multivariate log-linked Poisson regression analyzed associations, controlling for confounders.

Main Results:

• 44.2% of participants screened positive for probable khat dependence (SDS-khat).
• Positive screening was associated with increased khat use frequency (APRR=2.26) and higher risks of psychological (APRR=1.87) and physical (APRR=1.92) health problems.

Conclusions:

• Positive SDS-khat screening correlates with increased recent khat use and adverse health outcomes.
• The SDS-khat shows potential utility for healthcare providers in identifying individuals at risk of khat-related harm.
• Further research is needed to fully understand the relationship between khat dependence, use patterns, and health outcomes.
