[A path analysis of risk factors in relation to coronary heart disease].

The risk factors for CHD were analyzed with path analysis in this paper. The results suggested that in order of size the direct factors affecting CHD were physical activities, quantity of smoking, intensity score of life events, family history of CHD, social supports, systolic blood pressure, triglyceridemia, type B behaviour and the indirect factors were diastolic blood pressure, cholesterolemia, family position, weight index, state of falling asleep, and siesta. The relations among factors and the degree of every factor's influence on CHD were analyzed according to the path figure and the size of total effect of every factor. The structural model of risk factors for CHD was built.
