Predictors of enrollment in a health protection scheme among informal sector workers in Kumasi Metropolis of Ghana.

Approximately 17% of the participants were enrolled in NHIS. Respondents who had worked between 5 and 7 years were significantly more likely to enroll in NHIS compared with those who had worked below 2 years (AOR = 13.159, CI 1.135-152.596, p = 0.039). The study further found that apprentices (AOR = 0.72, CI 0.353-1.056, p = 0.005) were less likely to enroll in NHIS compared with their masters. Participants who were exposed to electrical hazards (AOR = 2.93, CI 1.56-5.10, p = 0.013) and suffered from occupational diseases (AOR = 2.75, CI 1.743-5.17, p = 0.001) were significantly more likely to enroll in NHIS. Also, respondents who were non-Christians were significantly less likely to enroll in NHIS compared with their respective counterparts (AOR = 0.726, CI 0.067-2.503, p = 0.011). The findings are useful for increasing the NHIS enrollment rate among informal sector workers in Ghana.
