Background
: The goals of this study are to investigate the propensity to depression and anxiety in children, and also, to investigate its relationship to the family structure, their life events, and school achievement. We have attempted to aid the continuous and comprehensive management of children with depression and anxiety in a field of family practice.

Methods : A group of 797 boys and girls in 5th and 6th were selected grades a elementary school in their, in the area of II-san and In-cheon city in August, 1997. Making use of the Kovacs' Children's Depression Inventory(CDI, 1977) and the Spielberger's State-Trait Anxiety Inventory for Children(STAIC, 1973), we investigated the propensity to depression and anxiety by self-rating. At the same time, the general characteristics(gender, age, residence, family structure), life events(death single parent, divorced family, death of a sibling, family discord between husband), and school achievement were investigated and assessed their relationship.

Results : The Children's Depression Inventory score was 11.69, the State Anxiety Inventory score was 31.51, and the Trait Anxiety Inventory score was 31.49. The CDI score were significantly higher in females, sixth year students, residents except for those living in an apartment or villa, and low school achievement group(P<0.01, P<0.05). There was no significance between CDI score and age, whether or not a dual-income family, death of a sib, hospitalization within 6 months, and family discord between husband and wife. The STAIC score was significantly higher for old age, female, sixth year students, and low school achievement group(p<0.01), and there was no significance between the STAIC score and residence, whether or not a dual-income family, death of a sibling, hospitalization within 6 months, and family discord between husband and wife.

Conclusion : According to our results, there was a significant correlation between gender, school years, school achievement and a propensity to depression and anxiety. Therefore, family physician should be more involved in family intervention and anticipatory guidance upon medical examination and treatment, if he or she has symptoms of anxiety and depression.

Background
: Recently, the concept of health is extended to physical, mental and social aspects, which leads people to pursue health behavior positively. But the evaluation of health condition shows a tendency to be biased to functional side. It this case, even if he is in physically good health, he is not rated as healthy. We analyzed the relationship between one's health state and the factors related with health perception including health behavior, mind and social environment.

Methods : For a month of May 1996, we surveyed those who visited for periodic medical check-up at one general hospital in Seoul. The questionnaire consisted of the total of 25 items ; diet behavior, weight control, coffee, coke, tea, drug use of, smoking, drinking, exercise, leisure, safety belts use, jay walking, sleep, stress, personality, anxiety, depression, occupational satisfaction, relationships with family and friends. Five point scale is used as the answer of each question item with high point as good living behavior. Among 406 who had sincerely answered the questionnaire, we divided them into healthy and unhealthy group and compared with the point of each question item and with the laboratory data(obesity, blood pressure, hemoglobin, fasting blood sugar, cholesterol and ALT).

Results : Among 406, the number of those who perceived themselves to be healthy was 175(43.1%, healthy group) and the one of those who did not was 231(56.9%, unhealthy group). The difference between both groups was not significant in distribution of sex, age, academic career, income and religion. In laboratory data and living behavior they showed same results, also. But the points of unhealthy group were significantly lower than those of healthy group in coffee, coke, tee, drugs usage, exercise, leisure, stress, personality, anxiety, depression, occupational satisfaction and relationship with family and friends. So was the total point of all items of unhealthy group in comparison with that of health group. In the case of male, the points of unhealthy group were significantly lower in smoking, safety belt use, jay walking, sleeping as well as the above items. On the contrary, in the case of female, both groups were not significantly different all items except exercise and leisure.

Conclusion : Health perception is influenced by psychosocial factors and living behavior more than by physical health. Therefore family physician must be concerned about patient's living behavior, mental and social problems and must make an effort to change their perception of health as well as physical improvement.

Background
: The obese patients increased recently in Korea due to excessive energy intake and decreased physical activity. We are well known that obesity is associted with an increased risk of cardiovascular disease, angina pectoris, hypertension, but not known to influence of weight gain to change in cardio-vascular risk factors. Once, the study of obesity are many but the study of influence of weight gain are small in Korea. This study investigated to influence of weight gain in cardio-vascular risk factors.

Methods : We gatherd case and control group among persons who has taken twice medical examination except disease person from October 1990 to October 1995 at SungAe General hospital. In our study, total 167 case, compare weight gain group(>3kg) with control group to change in cardiovascular risk factor.

Results : Sex, age, smoking history, obesity index were not statistically significant difference between two group in the first medical examination. systolic blood pressure, diastolic blood pressure, fasting blood sugar, HDL, total cholesterol/HDL were not statistically significant difference between two group for weight gain. Total cholesterol and triglyceride, LDL were stastistically significant increased.

Conclusion : Weight gain was increased of total cholestrol and triglyceride, LDL, so weight control was important.
