The sub-factors of health belief were health behavior and perceived susceptibility(r=.773, p<0.01), followed by self-efficacy(r=.760, p<0.01), and perceived severity(r=.574, p<0.01). The factors affecting health behavior were self-efficacy(β=.540, p<.001), perceived susceptibility(β=.461, p<.001), perceived benefits(β=.152, p<.05), marriage status(β=-. 100, p <.05), and income(β=-. 120, p <.05) in order.
