The purpose of this study is to investigate the nutritional status and blood constituents of the diabetics by obese index. All the measurements were taken from 501 (male 202, female 299) diabetics. Subjects were devided into 4 groups(underweight, ideal body weight, overweight, obesity) by obese index. 1) Energy intake was 1670-1900 Kcal in male diabetics and 1460-1560 Kcal in female diabetics. 2) In male diabetics, intakes of dietary cholesterol, protein food and polyunsturated fatty acid were significantly higher in underweight group than the other three groups. 3) In male diabetics, obese indices of RBW, BMI, WHR were observed to have significant positive correlation with alcohol intake(r=0.15, p<0.05). In female diabetics, WHR was observed to have a significant positive correlation with cholesterol intake(r=0.21, p<0.001). 4) In male diabetics, obese indices of RBW, BMI were observed to have significant negative correlations with total fatty acid(r=-0.16, -0.15), PUFA(r=-0.21, -0.20), total 6 fatty acid (r=-0.20, -0.19), and linoleic acid(r=-0.20, -0.19). In female diabetics, obese index of weight was observed to have significant negative correlations with total fatty acid(r=-0.13), saturated fatty acid(r=-0.13). 5) HDL (5) of diabetics was lower than normal level in all weight groups except underweight. VLDL(5) and serum TG(mg/dl) of diabetics was higher than normal level in all weight groups except underweight. 6) In male diabetics, obese indices of weight, RBW, BMI were observed to have significant negative correlations with HDL(r=-0.44, -0.29, -0.35), positive correlation with VLDL(r=0.39, 0.24, 0.30), and positive correlations with serum TG(r=0.25, 0.22, 0.24).

A health index was proposed that evaluates personal health state from both measured physiological variables and survey questions. Four health indices were defined such as cardiovascular index, stress index, obesity index, and management index. The total health index was calculated by summing these four health indices. Physiological variables such as blood pressure, heart rate variability(HRV), accelerated photoplethysmograph(APG), and body fat percentage were non-invasively measured and a survey questionnaire that asks personal health state, exercise intensity, and food preference was developed. The suggested health index was applied to thirty eight persons including 30 patients and 8 normal persons with an average age of 51.8. The average health index was estimated to be 75.1 out of 100 points. Young age group(below 50) and men group showed higher health indices than the aged(over 50) and women groups. The correlation coefficient between the cardiovascular index and stress index was found to be 0.513, which means stress is related to cardiovascular health state. The correlation coefficient between the measurements and survey questions was 0.385 for the cardiovascular index. It was as low as 0.182 for the stress index. More case studies may improve correlations between measurements and survey questions, and then, the current health index system may develop as an effective tool to evaluate personal health state.

The aim of this study is to provide fundamental data on the development of ready-to-wear clothes appropriate for the body types of elderly women. The study was conducted targeting 318 elderly women over 60 years of age whose fields of action were colleges for the elderly, sports centers, or business sites in Seoul and the neighboring districts. A total of 44 features in the upper body were used for the anthropometric measurement and analysis using anthropometry and photometry. The results of the study are as follows: 1. Somatotypes were classified into three types according to a cluster analysis using height and weight indices. Type 1 is the group with long and undersized upper body and straight body type since the face of the upper body is long relative to height and width, girth and depth are the smallest relative to weight, the breasts are somewhat fat, with a small extent of drooping and a straight back. Type 2 is the group that is considered fat relative to the body, has broad shoulders, drooping breasts with a wide space between them, and a back-bent upper body. Type 3 is the group that has a bent shape, the shortest upper body relative to height, and showing average obesity factors. 2. Indices of height and weight were used for factor analysis, cluster analysis, and discriminant analysis in order to classify upper body somatotype according to shape while excluding size factors of elderly women＇s upper body somatotype. The same method was used to compare and verify the result according to the absolute measurement and height index. Classification based on height and weight indices demonstrate that such somatotype classification minimizes the personal equation of body shape and it induces better classification based on shape as the results showed the highest cumulative sum of square(CUSUM) at 78.38% while six factors showed the smallest result and the hit rate for the classified three groups showed the highest result at 95.30%.

Background: Noise has been linked to an increased risk of various health issues, including stress, anxiety, insomnia, and cardiovascular disorders. However, research on the relationship between residential traffic noise and mental health in South Korea is limited. Objectives: This study aims to examine the correlation between regional traffic noise levels and mental health using an ecological study design. Methods: In this ecological study, all data were collected from the Korean Statistical Information Service. Traffic noise data in residential areas and the prevalence of mental health indices in 44 cities with noise monitoring stations were obtained. Pearson correlation coefficients were calculated to assess the relationship between regional traffic noise levels and mental health indices. Results: Daytime traffic noise levels were found to have a positive correlation with stress perception (r=0.428, p=0.004) and showed a borderline positive correlation with depressive symptom prevalence (r=0.273, p=0.073). In cities with airports, significant correlations was observed between 24-hour average noise levels and depressive symptoms (r=0.604, p=0.010), whereas this relationship was not observed in cities without airports (r=0.048, p=0.813). Multiple regression analysis, which adjusted for factors such as age, gender ratio, smoking, obesity, unemployment, urban size, and the presence of an airport, confirmed the relationship between 24-hour average noise levels and stress perception (beta=0.287, p=0.024). Conclusions: This study identified correlations between regional traffic noise levels and depressive symptoms or stress perception in adults, with a more pronounced effect in areas with airports. These findings suggest a potential impact of residential traffic noise on mental health, highlighting the importance of preventive measures like noise management in urban planning to promote mental well-being.

목 적 : 인슐린 감수성 지표들은 신체계측지수인 체질량지수 및 비만도와 상관관계를 보이는 것으로 알려져 있다. 그러나 이러한 신체계측지수들이 체지방량을 잘 반영하는 것으로 알려져 있기는 하나 소아에서는 성인에 비해 그 정확도가 떨어지므로 실제로 측정한 체지방량과 인슐린 감수성 지표들 간에도 이와 같은 연관성이 있는지에 대한 연구는 없는 실정이다. 따라서 본 연구에서는 단순 소아 비만아들을 대상으로 하여, 체지방측정에 있어 비교적 객관적이며 정확한 방법으로 알려진 BIA와 DEXA로 측정한 체지방량과 인슐린 감수성 지표들 간에 어떠한 연관성이 있는지 알아보고 추후 외래에서 비만아들을 추적 관찰할 때 어느 지표가 가장 유용한지 알아보고자 한다. 방 법 : 2002년 1월부터 2004년 7월까지 중앙대학교 용산병원 비만클리닉을 방문한 28명의 단순비만 환자를 대상으로 하였다. 12시간 이상 금식 후 채혈을 하여 혈당과 인슐린 수치를 측정하였다. 같은 날 신장, 체중, 허리 둘레, 엉덩이 둘레를 계측하였고, BIA와 DEXA를 시행하여 체지방량을 구하였다. 얻어진 혈당과 인슐린 수치를 이용하여 G/I ratio, $log_{insulin}$, HOMA-IR, $log_{HOMA-IR}$, QUICKI를 구하여 체지방량과의 연관성을 알아보았다. 결 과 : 1) 인슐린 감수성 지표 중 G/I ratio만 triglyceride와 통계상 연관성이 있는 것으로 나왔다(r=-0.206, P<0.05). 이외의 $log_{insulin}$, HOMA-IR, $log_{HOMA-IR}$, QUICKI는 혈중 지질치와 관련이 없었다. 2) 비만도는 G/I ratio와 -0.209(P<0.05), $log_{insulin}$과 0.196(P<0.05), HOMA-IR과 0.238(P<0.01), $log_{HOMA-IR}$과 0.198(P<0.05), QUICKI와는 -0.224(P<0.05)로 연관성이 있는 것으로 나왔고, 체질량지수는 G/I ratio와 -0.463(P<0.01), $log_{insulin}$과 0.417(P<0.05), HOMA-IR과 0.301(P<0.01), $log_{HOMA-IR}$과 0.403(P<0.01), QUICKI와는 -0.451(P<0.01)로 나와 비만도 보다 더 인슐린 감수성 지표들과 상관성이 높은 것으로 나타났다. 3) BIA로 측정한 체지방량과 비만도 및 체질량지수 각각에 대한 상관계수는 0.612(P<0.01), 0.316(P<0.05)으로 나왔고, DEXA로 측정한 체지방량과는 각각 0.667(P<0.01), 0.512(P<0.05)로 나와 체지방량과 비만도 및 체질량지수 사이에 연관성이 있는 것으로 밝혀졌다. 4) G/I ratio는 BIA로 측정한 체지방량 및 체지방률과 각각 상관계수 -0.420(P<0.05), -0.366(P<0.05)으로 상관성을 보이고 있었고, DEXA로 측정한 체지방량 및 체지방률과도 -0.512(P<0.01), -0.449(P<0.01)로 높은 상관성을 보였다. HOMA-IR은 DEXA로 측정한 체지방량과만 상관계수 0.341(P<0.05)로 연관성을 나타냈고, 그밖에 다른 인슐린 감수성 지표들은 체지방량 및 체지방률 모두와 상관성이 없었다. 결 론 : 인슐린 감수성 지표들과 비만도 및 체질량지수와 같은 신체 계측지수들 간의 상관성에서, 인슐린 감수성 지표 특히 G/I ratio가 비만도 및 체질량지수 모두와 높은 상관성을 보였고, 체지방량 및 체지방률과 인슐린 감수성 지표와의 관계에서는 G/I ratio만이 BIA와 DEXA로 측정한 체지방량과 체지방률 모두와 연관성이 있는 것으로 나타났다. 따라서 단순 비만아의 진단 및 추적 관찰시 BMI 및 인슐린과 혈당치를 기초로 한 인슐린 감수성 지표 특히, G/I ratio의 활용이 임상에서 유용하게 사용될 수 있을 것으로 생각된다.

The purpose of this study was to investigate the relation between bone mineral density and nutrient intake among normal and obese elementary students. Each subject was assigned to one of such as normal (n = 69) and obese groups (n = 94) according to their obesity indices. And they were asked for general characteristics, dietary habits and nutrient intakes using questionnaires and 24-hr recall method. They measured the sound of speed (SOS) of calcaneus using quantitative ultrasound. The averages age of the subjects were 10.6 years in normal and 10.7 years in obese group. The averages weight (p < 0.001) and obesity index (p < 0.001) of the normal group were significantly lower than those of the obese group. In dietary habits, the obese group in boys was the higher skipped breakfast than normal group (p < 0.01). The plant calcium intake of obesity in girls was lower than those of normal group (p < 0.05). The SOS in the calcaneus was 1697.6 m/s in the obese group and 1763.7 m/s in the normal group (p < 0.01). The SOS in the calcaneus was negatively correlated to weight (p < 0.01), obesity index (p < 0.001) and percent of body fat (p < 0.01). Also the SOS in the calcaneus was positively correlated plant calcium intake (p < 0.05). In conclusion, the excessive increase of weight and percent of body fat in elementary students appeared to have negative impact to bone health. And based on these results, further studies on the effects on bone mineral density of obese and nutrient intakes in needed for proper bone health.

본 연구는 귤피가루를 활용하여 모닝빵을 개발하고 이를 대학기숙사에 거주하고 있는 과체중 및 비만인 20대 남 녀에게 섭취하게 해봄으로써 아침결식률을 낮출 수 있는 새로운 식품 소재를 개발하고자 실시되었다. 체중과 BMI의 경우 GB 섭취군과 CPB 섭취군 모두에서 감소하였으며, CPB 섭취군에서 사전에 비해 사후 유의적으로 체중과 BMI가 감소한 것으로 나타났다 (p < 0.05). WHR은 GB 섭취군에서는 증가하는 경향을 보였으나 CPB 섭취군에서는 유의적으로 감소하였다 (p < 0.05). BFM은 두군 모두에서 유의적으로 증가하였으며 (p < 0.05) 군간에 유의성을 띄지 않았다. TC는 GB 섭취군에서는 증가하는 경향을 보였으나 CPB 섭취군에서는 유의적으로 감소하였다 (p < 0.05). HDL은 두군 모두에서 증가하였고 GB 섭취군에서 유의성을 보였다 (p < 0.05). LDL은 두군 모두에서 유의적으로 감소하였으며 (p < 0.05) 군간에 유의성은 없었다. GOT와 GPT는 GB 섭취군과 CPB 섭취군 모두에서 감소하였고 CPB 섭취군에서 유의성을 보였다 (p < 0.05). GB와 CPB를 섭취한 군간에 신체계측치와 혈액생화학적 수치에서 유의적인 차이를 보이는 항목은 없었으나 CPB 섭취군에서 사전에 비해 TC, LDL, GOT, GPT 수치가 유의적으로 감소하였다는 점에서 (p < 0.05) 본 연구는 시간적 흐름에 따라 변화를 추적하는 종단적 연구에 가깝다고 판단되며 본 연구를 통하여서 귤피가 심혈관계질환의 유병률을 낮춰줄 수 있는 잠재적 가능성이 있음을 임상적으로 확인하였다. 따라서 향후 본 연구와 유사한 연구들이 double blind cross-over study와 같은 대규모 임상연구로 진행되어 귤피의 지질관련 효과들을 보다 명확하게 입증해줄 필요성이 있을 것으로 판단된다.

The purpose of this study was to investigate weight control practices and cardiovascular risk in middle-aged women. 304 middle-aged women were selected as subjects from thirties to fifthies living at J city in Chung-Buk Do. Data were collected using a questionnaire, anthropometric measurements, BP & total cholesterol level in serum from April 1, to June 30, 2003. The results of this study were as follows: The middle-aged woman's age is average $43.95{\pm}7.09yr$ and mean BMI(body mass index) was $23.54{\pm}3.09\;kg/m^2$. Underweight, normal weight, overweight, obese women were 3.0%, 39.5%, 27.9% and 29.6%respectively. Subjects perceived own as 'Slim' 5.9%, 'ordinary' 45.7%, 'Fat' 48.4%. Their weight perception coincide their own actual body weight but as many as 41.8% of overweight and 9.0% of obese perceived themselves as being 'ordinary'. Middle age women with past weight control experience were 55.6%, and only 35.5% was doing weight control at present. Of these subjects, 71.4% reported wanting to lose weight and the primary reason of weight control was to improve their appearance(39.53%). The most frequently reported weight control behavior was 'exercise' followed 'dieting', but 39.6% reported using 'diet food', 12.4% 'behavior modification', 12.4% 'fasting', and 'diet-drug'(3.6%) or 'smoking'(3.6%). Effective weight control methods were thought regular exercise(97.1%) & dieting (79.3%). And behavior modification(71.4%) or diet camp(60%) were effective, too. An average waist circumference was $79.80{\pm}9.47cm$, waist/hip ratio was $86.63{\pm}6.78$, waist/height ratio was $50.43{\pm}6.10$. In the index of abdominal obesity, 79.7 % of middle-aged women was waist/height ratio over 0.46, 65.3% was waist/hip ratio over 0.85, 28.4% was waist circumference over 85cm. There were significant differences in the degree of abdominal obesity according to age and BMI. In the index of cardiovascualr risk, 10.9% of middle aged women was systolic hypertension over 140mmHg, 18.7% was diastolic hypertension over 90mmHg and 10.6% was hypercholesterolemia over 200mg/dl. There was significant difference in systolic hypertension ratio according to age. There was significant difference in diastolic hypertension ratio according to age and obesity. There were significant differences in hypercholesterolemia accorting to obesity. The abdominal obesity indices and the levels of T-cholesterol in the serum, systolic and diastolic BP increased significantly according to age. T-cholesterol in serum was predicted 2.6% by waist/height ratio. And systolic BP was predicted 15.2% by waist/height, add BMI to 16.8%. Subject's diastolic BP was predicted 12.1% by BMI. Therefore waist/height ratio and BMI were significant factors for the predictors of cardiovascular risk. There was significant correlation between index of obesity and cardiovascular risk. T-cholesterol in serum had correlation with waist/eight ratio(r=0.174) and waist circumference(r=0.48). Systolic BP had correlation with waist/height ratio(r=0.387), and BMI(=0.371). diastolic BP correlation had correlation with BMI(r=0.343) and waist/height ratio(r=0.327). In conclusion, The prevalence of obesity was 29.6% in 304 cases, and increased as age after menopause increased. Middle-aged women's weight perception and actual BMI coincide but some of them did not. Trial to reduce weight was attempted. But most of them did not actually. Undesirable weight control method such as using drugs, fasting, smoking was used by some women. It is important to educate about health weight control methods and raise their awareness of exact body figures. High frequency of abdominal obesity in middle-aged women had correlation with hypertension and hypercholesterolemia. Abdominal index such as waist/height ratio, waist circumference, waist/hip ratio was used. Women's hypertension, hypercholesterolemia significantly related to body mass index and abdominal obesity.
