A longitudinal causal relationship among cardiovascular risk factors in the employees of the government savings bank

Abstract

A longitudinal structural causal model was generated to examine the causal relationship among determinants which were composed of four personal factors, stress, four health behaviors, and BMI on five physiological risks for cardiovascular disease: SBP, DBP, FBS, TC and HDL-C in 1,019 bank employees, within a five-year interval. A fourteen-item food frequency questionnaire for assessing eating habits and the Health Opinion Survey for the stress test were included in the self-administered questionnaires. Weight, height and blood pressure were measured and blood samples were collected for blood chemical analysis. Data analysis by LISREL showed that the determinants in the proposed model explained as much as 96 per cent variation in physiological risks for CVD (R2= 0.96, relative chi-square = 1.92, RMSEA = 0.03, GFI = 0.96 and AGFI = 0.95). The findings also indicated that current physiological status was affected by their status of age, education, health behaviors, BMI and physiological status 5 years ago.
