Objective: To evaluate the knowledge, attitude and behavior on blood lipid among people in Changsha and to provide evidences for prevention and control of blood lipid abnormality.
Methods: A total of 400 cases were randomly selected on the questionnaire of the knowledge, attitude and behavior on blood lipid in ordinary adults who participate in health examination in Xiangya Hospital. Blood lipid related physical examination was conducted at the same time. The health examination participants were divided into several groups according to their sex, age, degree of education, marriage and family income. The influential factors for knowledge, attitude and behavior were analyzed.
Results: The knowledge score of blood lipid for health examination participants was 18.33±8.67 (total score 37), the attitude score was 6.63±2.45 (total score 9) and the behavior score was 8.32±2.65 (total score 16). The scores of female was higher than that of male in the terms of knowledge and behavior (both P< 0.05); the scores in the 40-49 age group were lower than those in the other age groups (all P< 0.05); the scores in the junior high school group were lower than those in the other education groups (all P< 0.05); the scores in the family group with less than 2 000 yuan income were lower than those in other family groups with different income (all P< 0.05). The multiple stepwise regression analysis showed that: 1) the knowledge on blood lipid score was influenced by ages and education background (both P< 0.05); 2) while the attitude of blood lipid was influenced by four factors such as education background, systemic blood pressure, blood sugar and triglyceride(all P< 0.05); 3) the behavior on blood lipid was influenced by five factors such education background, triglyceride, systemic blood pressure, blood sugar and ages (all P< 0.05).
Conclusion: The knowledge, attitude and behavior on blood lipid among health examination participants were mostly influenced by education background, gender and ages. Thus, clinical medical staff should prevent the blood lipid abnormality through the health education and improve the knowledge in normal people. The group of 40-49 age male should be thought as the primary intervention subjects. The knowledge, attitude and behavior on blood lipid among the general population is also related to individual's blood pressure, blood sugar and triglyceride. So the clinical medical staff should also improve the knowledge of blood lipid, blood pressure and blood sugar in general population for improving their attitude and unhealthy habits. In addition, the active control of blood sugar and blood pressure can enhance the overall health status of the general population.
