Background/purpose Khat chewing, a green leaf with amphetamine effects, is a public health concern. Yet, it is prevalent and evident, in the khat belt region, among male students in health faculties. This study aimed to examine whether psychosocial factors have a protective impact on khat chewing among male dental and medical students. Materials and methods A cross-sectional study included all students (1457) in second year and above at a Yemeni university. A self-administered questionnaire was used to obtain sociodemographic data and to assess students’ psychosocial characteristics namely, depression, resilience and social support (perceived or received [living with or away from family]). Data analysis included descriptive statistics and multivariable logistic regression modelling. Results The response rate was 61% (male = 334, female = 547) and the responding students' mean ± SD age was 22.95 ± 1.56 years. Of the respondents 185 (21% [95%CI = 18%–24%]) were current khat chewers (7 [4%] females and 178 [96%] males respectively). In the adjusted model, among male students living away from family was significantly associated with khat chewing (adjusted odd ratio [AOR] = 3.15,95%CI = 1.96–5.07, p < 0.001) and perceived social support was inversely significantly related to khat chewing (AOR = 0.98; 95%CI = 0.96–1.00; p = 0.019). Conclusion Within the limitation of the study of a single institute, social support whether received (living with family) or perceived appeared to be a protective factor from khat chewing among male medical and dental students. Social support should be enhanced and targeted to discourage khat chewing during the preparation of this future health care force.
