Demographic variables such as marital status, educational level, income, age, work experience and employment status (p <0.05), as well as all SCT constructs (p <0.05) had a significant relationship with knowledge. Logistic regression analysis revealed that the level of education and employment status with probability of 80.6% and self-control, environment and self-efficacy of perceived barriers constructs, with a 64% probability could explained workers in high-knowledge group.
