There was a significant relationship between using daily sunscreen with sex (female) and higher economic status (P<0.05). The Health Belief Model (HBM) variables predictor accounted for 27% of the variation in the outcome measure of use the sunscreen. Perceived barrier (Beta = -0.290 and P<0.001), Perceived benefits (Beta = 0.242 and P< 0.001) and cues to action (Beta = 0.155 and P= 0.006) were the more influential predictor on sunscreen use.
