The study subjects are teachers of elementary. middle and high school. and staffs of research institutes located in Chungchung Province and Daejon city. The data was collected from Jan. to march 1997 through self reporte for structured questionnaire. Fantastic check list of Wilson and Ciliska for Health Lifestyle Assessment and DSM-III-R for somatic symptom were used as tools. Data was analysed by frequency, $X^2_test$, t-test and Anova using SAS program. The results are as follows: 1. There were statistically significant differences In drinking(t=7.75, P=.000), exercise(t=-2.99, P=.003)and interpersonal relationship(t=2.22, P=.027) among 10 health lifestyle between smoking group and non-smoking group, in drinking(t=17.98, P=.000), exercise(-4.71. P=.000), and job satisfaction(t=2.22, P=.027) between drinking group and non-drinking group, and in eating habit(t=-2.00, P=.045), drinking (t=4.47, P=000), exercise (t= -16.49, P=000), keeping traffic law(t= -2.68, P=.007), personality (t= -2.05, P=.040) and anxiety/depression(t=-3.47, P=.000) between exercise group and non-exercise group. 2. There was statistically significant difference in cardiovascular symptom(F=4.22, P=.0l) among somatic symptoms of subjects according to exercise level. 3. There was statistically significance difference in lifestyle according to smoking level(F=, 3.33, P=.011), drinking level(F=9.17, P=.0001) and exercise level(F=11.93, P=.000l), and in somatic symptom according to sex(t=-3.93, P=.0001), weight(F=3.83, P=.022), exercise level (F=3.29, P=.03) among general characteristics. 4. There was statistically significant difference between sex in general (t= -3.64, P=.0001), gastrointestinal(t=-2.21, P=.02), musculoskeletal(t=-3.92, P=.001), and total symptom (t= -3.92, P=.0001). 5. There was statistically very highly signigicant difference In weight according to smoking($x^2=25.18,\; P=.001)$ and exercise$(x^2=16.46,\; P=001)$. 6. There was statistically significant difference in frequency between smoking group, drinking group and exercise group$(x^2=24.52,\;P=.001)$. Among a number of habit, smoking, drinking and exercise are important factors of human health to prevent related disease morbidity and death. It is essential for industrial health nurse to committ in this subject considering the influence of those factors and lifestyle on health. There is also a relationship of weight with smoking and exercise, the frequency of overweight/obesiy in smoking/ no-exercise group were high. It is quite necessary for the people having cardiovascular symptom to exercise to lower morbidity and mortality. The industrial health nurse has to keep In mind on this point and consider of time and facilities of fitness of employee. It needs to explore the cause by further research on somatic symptom of women. This research shows that concerning the relationship between smoking, drinking, and exercise, health care provider must take not only management of disease, but health behaviors and lifestyle into consideration.
