- The author surveyed overall obesity indicies and factors concerned with obesity such as dietary intake, physical activity, stress and life style with the subject of doctors. The number of subjects was total 508 with 396 men and 112 women. They were subgrouped into surgical part, medical part and service and basic part by speciality. And also subgrouped into intern and resident, pay doctor, and practitioner by working type. The results were as follows. 1) Obesity indices: BMI of total doctor was 23.1+/-2.8, and WHR was 0.87+/-0.08 and overweight prevalence(BMI>25.0) was 23.6 %. It was within normal limit but slightly over the Korean standard. The degree of obesity indices of subgroups by speciality was "surgical part > medical part > service and basic part", and by working type was "practitioner > pay doctor > intern and resident". 2) Dietary intake and Physical activity: Average dietary intake was 2148+/-451 kcal/day. The degree of dietary intake by speciality was "surgical part > medical part > service and basic part". By working type it was "practitioner > pay doctor > intern and resident". Average physical activity was 29+/-5 METs/day. The degree of physical activity also showed similar pattern. But there was no significant difference among each groups. 3) Comparison between over-weight and non-over-weight group: The items that showed significant difference between two groups were dietary intake, skip breakfast, regular exercise, smoking, heavy drinking, chronic disease etc.

- This is a cross-sectional study to evaluate the serum lipid levels of children living in Pusan in 1996. The distribution of age is from 2 years old to 12 years old. In female children mean total cholesterol is 171.4+/-26.2mg/dl, triglyceride is 104.7+/-50.6mg/dl, HDL-cholesterol is 54.4+/-14.8mg/dl, and LDL-cholesterol is 95.4+/-32.9mg/dl. In male children mean total cholesterol is 167.9+/-25.2mg/dl, triglyceride is 90.6+/-45.5mg/dl, HDL-cholesterol is 55.4+/-11.7mg/dll, and LDL-cholesterol is 94.4+/-23.6mg/dl. The percentile of serum lipid levels is measured in children. The 95th percentile of serum total cholesterol is 210mg/dl in male children, and 214mg/dl in female children. And, the 95th percentile of serum triglyceride is 184mg/dl in male children, and 191mg/dl in female children. And, the 95th percentile of LDL-cholesterol is 133mg/dl in male children, and 135mg/dl in female children. Serum total cholesterol is positively related to age(r=0.18), height(r=0.08), weight(r=0.17), obesity index(r=0.12), and negatively related to father's education level(r=-0.13), mother's education level(r=-0.13). Serum triglyceride is positively related to weight(r=0.23), age(r=0.31) and negatively related to father's education level(r=-0.12), mother's education level(r=-0.18). Serum HDL-C was positively related to mother's education level(r=0.07) and negatively related to height(r=-0.12), weight(r=-0.09). Conclusively, the serum lipid levels of children living in Pusan is generally so high that the family and school must try to control the serum lipid levels.

Abstract

- Helicobacter pylori is now recognized as causative agent of chronic gastritis and peptic ulcer, and strongly associated with development of gastric carcinoma. With development of sensitive and specific serologic tests to identify individuals infected with Helicobacter pylori, the epidemiologic study of this diseases has been investigated. But it's transmission route is not established, yet. The purpose of this study is to measure the prevalence of Helicobacter pylori infection in healthy children and young adults and to evaluate related factors for Helicobacter pylori infection in Korea. The seroprevalence of Ig G antibodies to Helicobacter pylori was determined using a Enzyme Linked Immunosorbent Assay and we obtained the information, such as demographic characteristics, monthly household income, numbers of family members in the house, numbers of persons using same room, type of house, and type of drinking water through the questionnaire survey. The observed overall seropositivity rate was 25.7%. The rate is increased progressively from 5.8% in the age group 1~3 years to 44.4% in the age group 20~29 years(chi-square for trend, p<0.001). Especially, the rate increased steeply from 6.5% in the age group 4~6 years to 20.8% in the age group 7~9 years, and this suggested that elementary school age was the major acquisition time of Helicobacter pylori infection. In multivariate logistic regression model, age, numbers of family members in the house, and type of house was statistically significant variables for Helicobacter pylori infection. Each odds ratio(95% CI) were as follows; base to age group 1~9 years, age group 10~19 years 3.6(2.0~6.4), age group 20~29 years 7.3(4.1~13.1) and base to group of 1~3 family members, groups of 4~5 family members 2.1(1.1~4.0), group of 6 or more family members 2.7(1.3~5.4) and base to apartment, single and multihouse 1.9(1.1~3.5). Sex, monthly household income, numbers of persons using same room, and type of drinking water was not statistically significant for Helicobacter pylori infection.

Abstract

- To investigate the factors which affecting the cognitive impairment of the 60 or more age group, the authors surveyed for the subjects in some area of Kyungnam Province. 201 studied subjects were tested for cognitive function with mini-mental state examination(MMSE). Information on demographic characteristics and life style has been collected through direct interview. The concentration of Al and Ca of subject's drinking water, which might be related with cognition, was measured by Inductively Coupled Argon Plasma Spectrometer. The main results were summarized as follows. 1. The prevalence rate of cognitive impairment was 18.4% in male and 45.2% in female and this sexual difference was statistically significant(p=0.03). And the uneducated or illiterated showed significantly high prevalence rate of cognitive impairment(p=0.02). 2. In stratified analysis by sex and education year, we can not see significant trend indicating the neurotoxic effects of aluminum and protective effects of calcium to the cognitive function(p>0.05). 3. The correlation between the concentration of aluminum in drinking water and the MMSE score in whole subjects showed weak negative relationship(r=-0.066). But there was no statistical significance(p=0.434).
