The purpose of this study was to compare the validity of obesity indices among the body mass index (BMI), waist circumference (WC), and body fat percentage (BF%), and to determine which is the most useful index to predict the risk of chronic diseases of elderly people. This study was conducted as a cross-sectional study at welfare centers in Seoul. The total number of subjects was 261 (68 men and 193 women) with age ${\geq}60$ years. The distribution of obesity using 3 obesity indices in the subjects with hypertension, diabetes, or arthritis was BF%>WC>BMI in elderly men and WC>BF%>BMI in elderly women. In elderly women, odds ratios (ORs) for hypertension in BMI and WC quartiles were significantly increased in quartile 2 and 3 (p<0.05). The ORs for hypertension, hyperlipidemia, and arthritis in BF% quartiles were significantly increased in quartile 3 and 4 (p<0.05). The BF% was sensitive obesity index for predicting the occurrence of chronic disease in men, and the WC was sensitive index in women. Our results suggested maintaining BMI less than $23.5kg/m^2$, WC less than 82 cm, and BF less than 35% in order to prevent chronic diseases in elderly women.

Objectives : In order to investigate the relation of body composition analysis and isokinetic trunk muscle strength for the screening test of low back pain. Methods : This study was carried out with the data from comprehensive medical testing. 75 subject aged 20-59 performed the segmental bioelectrical impedance analysis, isokinetic trunk muscle strength test and questionnaire. Then we analyzed the relationship of data. Results : Low back pain(LBP) prevalence in high obesity index(Body mass index(BMI), Percentage of Body Fat(PBF), Waist Hip Ratio(WHR)) group was higher than LBP prevalence in normal obesity index group(p<0.001). In LBP group, Extension Peak Torque(Ext.PT), Extension Peak Torque per Body Weight(Ext.PT/BW) were significantly lower than Non-LBP group(p<0.001). And 90% of LBP group indicated abnormal Extension-Flexion Ratio(E/F ratio)(1.0 < Normal E/F ratio <1.6). When it comes to analyze relation between obesity index and muscle strength, Ext.PT/BW was significantly decreased according to PBF, WHR score. And correlation coefficient in Flex.PT, Flex.PT/BW, Ext.PT, Ext.PT/BW and PBF showed decreasing function. Conclusions : Results from this investigation showed positive correlation between obesity and LBP prevalence. Decreased muscle strength and inbalanced E/F ratio were shown in LBP. Trunk muscle strength was changed according to body mass composition parameters. This results are expected to contribute to prevent and diagnose LBP by application the clinical index of body composition analysis.

The objectives of this study are to estimate the prevalence of diabetes mellitus (DM) and to identify risk factors associated with fasting blood sugar in a rural adult population. We carried out a cross - sectional study on the residents over 30-year old. Among the 1077 eligible subjects, 725 persons responded to the study;the study consisted of interview on family and past history of DM, anthropometry, blood pressure, and blood sugar level in each subjects. Only 707 subjects of 725 participants had fasting blood sugar(FBS) examined and the rest, 18 subjects were had casual blood sugar examined due to failure of fasting over 8 - hour. When subjects had $FBS\geq140mg/dl$, 2 hours postprandial blood sugar level was checked after 75g oral glucose loading. The prevalence of DM was 8.9%, and age standarized prevalence rate adjusted to Korean population of 1995 was 5.8%. Mean and SD of fasting blood sugar in men was $99.8{\pm}22.6$, and in women was $111.5{\pm}29.9$. Mean levels of fasting blood sugar were significantly higher in women than in man and as their ages advanced the prevalences increased in both sexes. PP2 blood sugar levels were significantly higher in elder age and in persons with higher FBS levels than others. The risk factors associated with FBS were past history of diabetes, sex, socioeconomic status and waist - to - hip circumference ratio;the risk of diabetes was increased in female, people with past DM history, central obesity and low socioeconomic state. The low socioeconomic status associated with DM in this study, which is different from other study results, should be pursued in further studies.

There is only limited evidence for the association between fruit and vegetable consumption and mental health in Korea. This study examined the relationship between fruit and vegetable consumption and mental health according to physical activity among Korean adult women. Based on data of the Korean National Health and Nutrition Examination Survey (2014-2016), a total of 5,332 participants were included in this analysis. With increasing fruits and vegetables consumption, the prevalence of depressive mood was significantly decreased (p for trend=0.0248). The prevalence of stress perception (p for trend=0.0422) and the prevalence of depressive mood (p for trend=0.0300) were decreased with increasing fruit consumption. The prevalence of depressive mood was significantly decreased when fruit and vegetable consumption (p for trend=0.0370) and fruit consumption (p for trend=0.0356) were increased for those Korean women with low intensity of physical activity. For the obesity group (Body mass index 25 kg/㎡), the prevalence of depressive mood was decreased with increasing fruit and vegetable consumption (p for trend=0.0111) and increasing fruit consumption (p for trend=0.0165). In conclusion, fruit and vegetable consumption were associated with mental health according to physical activity among Korean adult women. Further prospective studies are warranted to explore the association between fruit and vegetable consumption and mental health among Korean adult women.

Background: Repetitive hand use increases the risk of hand osteoarthritis (OA). This study aimed to investigate characteristics of and risk factors for hand OA in Korean women farmers. Methods: This cross-sectional study included women farmers resident in Jeollanam-do, Korea. The participants were interviewed, and radiographs were taken of both hands. Radiological hand OA was defined based on the Osteoarthritis Research Society International imaging criteria of joint space narrowing or the presence of osteophytes. The participants were divided into age groups of < 60 and ≥ 60 years. Obesity was defined as body mass index of > 25 kg/m². Annual working time was divided into < 2,000, 2,000-2,999, and ≥ 3,000 hours. Agricultural working type was divided into rice farming and field farming. Robust Poisson regression was used to identify factors associated with radiographic hand OA, with adjustment for age, obesity, annual working time, and agricultural classification. Results: A total of 310 participants with a mean age of 58.1 ± 7.6 years, were enrolled. The prevalence of radiologically confirmed OA was 49.0%, with an OA prevalence of 39.4% the interphalangeal joint in the thumb (IP1). The prevalence of OA was higher in the distal interphalangeal joint than in the proximal interphalangeal, metacarpophalangeal, and carpometacarpal joints. The prevalence of OA varied by age, annual working time, and agriculture type. Conclusions: Korean women farmers have a high prevalence of OA, particularly in the IP1 joints. OA is associated with age, working hours, and agriculture type.

Objectives: The aim of this study was to investigate the prevalence of metabolically obese, normal-weight (MONW) phenotype and the association between lifestyle factors and the risk of MONW in Korean adolescents. Methods: Normal-weight (BMI, 5th to 85th percentile) subjects with ${\geq}1$ metabolic abnormalities were categorized as MONW phenotype. Data from adolescents aged 12 to 18 years who have participated in the Korean National Health and Nutrition Examination Survey in 1998 (n=751) and 2008 (n=455) were analyzed. Physical activity and dietary intakes were assessed. Results: The prevalence of hypertension and hyperglycemia in 2008 decreased compared with that in 1998 (P<0.001) but the prevalence of abdominal obesity, hypertriglyceridemia and low HDL did not changed. The overall prevalence of MONW in Korean adolescents declined over 10 years (P<0.001). Adolescent boys and girls engaging regular exercise significantly increased over 10 years (P<0.01). Physically active adolescents had a lower risk of being MONW in 1998. Dietary intake patterns were not associated with a risk of MONW. Conclusions: The prevalence of MONW among Korean adolescents declined over 10 years which may be due to the decreased prevalence of hypertension and hyperglycemia. The risk of MONW would be lower in individuals who are physically active.

Objectives : The objective of this study is to assess the prevalence and risk factors of metabolic syndrome (MS) among inpatients with schizophrenia, and to compare with general population. Methods : Nine hundreds seventy inpatients were included to assess the prevalence of MS from two mental hospitals in Yong-in city. Assessment of MS was performed based on modified American Heart Association criteria with abdominal obesity threshold of 90cm for men, 85cm for women. Comparative analysis was performed using age- and gender matched sample from Korea Health and Nutritional Examination Survey III. For evaluating risk factors, analysis included 766 inpatients taking consistent medications at least for 30 days. Results : The prevalence of MS of inpatients with schizophrenia was 26.2%, in females it was 33.2%, compared to 20.2% in males(p < 0.001). Compared to general population, the prevalence of MS was significantly lower in male and higher in female patients. In terms of criteria prevalence, who met abdominal circumference criterion were more prevalent in patient group(p < 0.001). After multivariate analysis, female gender and old age remained as risk factors of MS. Conclusions : The prevalence of MS of inpatients with schizophrenia was 26.2% and significantly low compared to general population. Female gender and old age were risk factors of MS.

Objectives Identification of individuals predisposed to obesity is an important issue for prevention and control of the obesity. It was reported that a high prevalence of obesity appeared in Taeumin among Sasang constitutions, but Enneagram personality-types has not been used to classify the patterns of obesity. These two classification methods were employed in combination in the current study, and it was analyzed whether the morbidity pattern of obesity can be characterized in further detail. Methods The subjects were 125 University students(62 males and 63 females) who answered both questionnaires for Sasang constitutions and Enneagram personality types. The obesity of students was classified by the obesity index and BMI. Results Only Taeumin group of Sasang constitutions was overweight, and the male of the group was overweight or obese. Analysis of the obesity index and BMI according to the Enneagram personality types showed significant differences(p<.05) between the types in the female group. These values were highest at the type 3 and lowest at the type 4. The physical indices according to both the centers of Enneagram and Sasang constitutions showed that only Taeumin female group had significant differences(p<.05) in the obesity index and BMI. Taeumin male group was overweight or obese in all centers of Enneagram and Taeumin female group was overweight or obese only in heart-center. Conclusions Diagnosis of the present data suggest that the classification of obesity patterns using Enneagram personality types in addition to Sasang constitutions is very useful to prevent and control the obesity.

Obestity, characterized by an excess accumulation of fat, is a detriment to good health and wellbeing. It is easy for individuals to take on excess fat as soon as enough food and leisure are available in a society, causing an imbalance between energy intake and energy expenditure. Although there has been disagreement as to which side of this energy equation is more important in th epidemic of obesity, both sides are certainly involved. I think the prevalence of obesity begins with infancy. It seems to be relatively constant throughout childhood. Some retrospective studies have suggested that there is a direct progression from a fat chile to a fat adult. Obesity has been associated with excess mortality in many studies. The effect of obesity on cardiovascular disease has not always been an independent one, but has generally been through exacerbation of other rish factors such as hypertention, diabetes, hyperlipedmia, galbladder disease, gout and cancer of the grease and endometrium. The weights of identical twins raised in separate homes have been reported to be similar, thereby suggesting that heredity contributes significantly to weight. Overweight and obesity are by far greater health problems for many people in our society. Therefore in this paper we consider the relationship between body energy balance and problems of obesity. Whatever the weight of the person, the goal of the nutritionist and health care workers is to find solutions that will allow persons to feel better about themselves.
