- Obesity usually is defined as the presence of and abnormally amount of adipose tissue. In many epidemiologic study, obesity as a health risk factor has been estimated by Body Mass Index(BMI) in general. This study was conducted to review of body fat percent measured by Bioelectric impedance analyzer as a estimator of obesity in a rural adult population. The study subjects were 421 men and 664 women who reside in the area on the Juam lake. They were sampled by multistage cluster sampling. Their mean age was 59 years old. Body fat percent increased with age, but BMI decreased with age in this study. Body fat percent was more larger at female and elder on the same BMI. The correlation coefficient between with body fat percent and body mass index was low (r=0.4737). Body fat percent was explained by not only BMI but also sex and age (r(2)=0.63). The result suggested that it is inadequate for BMI only to estimate obesity about elderly person who reside in the rural community. The relation of body fat percent and body mass index of this study agreed with the preceding knowledges and studies in general.

- In order to investigate the prevalence and the factors related to the depression and burnout among private practice physicians, a SDS(self-rating depression scale) and MBl(Maslach burnout inventory) -based questionnaire study was performed on 344 private practice physicians in Kwangju and chonnam area. The results were summarized as follows. 1. Mean SDS score was 38.3 in total subjects and the prevalence rate of depression was 48.8%. As for the frequency order of the items of the SDS, decreased libido, diurnal variation and hopelessness were relatively high, and suicidal rumination, constipation and agitation were noted low. 2. Noticeable factors related with depression were smoking, coffee use, sleeping time and satisfaction with income. 3. As a result a factor analysis with the MBl data, five factors named as emotional exhaustion, depersonalization, personal accomplishment, involvement and self-interest were extracted. Statistical analysis of the data demonstrated that 48.8% of the physician sample reported high scores on emotional exhaustion, and 45.3% scored high on depersonalization. Personal accomplishment scores remained high with 45.3% reporting high personal accomplishment. 4. Variables related to the burnout were age, sleeping time, family size religion, medical speciality. duration of practice setting, visiting patient number, closing day per month and job satisfaction. 5. In the relationship with depression, burnout was closely related to depression. Above results showed that the high percentage of private practice physicians experiencing depression and burnout suggests the need for further research to establish trends, to identify causal factors, and to develop avenues to reduce stress.
