Moreover, the x 2 comparison in this study found an alarming pattern that market workers at higher risk for AI appeared to be less likely to adopt preventive behavior than shoppers and other market workers with lower risk for AI. Further, an ancillary analysis (data not shown) indicated that these high-risk market workers also had a significantly lower level of education, which was associated with lower compliance with recommended preventive behavior. Taken together, more attention should be paid to this group of high-risk market workers. It is worth noting that the aforementioned x 2 comparison of AI preventive behavior was not statistically significant, possibly owing to relatively smaller cell counts of high-risk market workers and hence reduced statistical power. Therefore, future studies may consider increasing not only the total sample size but also the number of high-risk market workers so as to confirm the above-noted pattern.
