Critical health literacy was a significant influence of preventive lifestyles. The Malay ethnic group has the highest scores for both critical health literacy [F (3, 739) = 17.82, p p = 0.025]. The other Native groups scored the lowest for critical health literacy. Individual with higher score of critical health literacy tend to perform physical activities.
