Background: There have been many studies on the associations between body mass index (BMI) and cognitive function. However, no study has ever compared the associations across the methods of categorizing BMI. In this study, we aimed to fill the gap in the previous studies and examine whether the obesity paradox is valid in the risk of cognitive function. Methods: Of the 10,254 people aged 45 and older from the Korean Longitudinal Study of Ageing from 2006 to 2016, 8,970 people were finalized as the study population. The dependent variable was whether a person has a normal cognitive function or not, and the independent variables of interest were BMI categorized by the World Health Organization Western Pacific Regional Office (WHO-WPRO) method, the WHO method, and a 10-group method. Covariates included sociodemographic factors, health behavior factors, and health status factors. A generalized linear mixed model analysis with a logit link was used. Results: In the adjusted model with all covariates, first, in the case of BMI categories of the WHO-WPRO method, underweight (odds ratio [OR], 1.16; 95% confidence interval [CI], 1.15-1.17), overweight (OR, 1.36; 95% CI, 1.35-1.36), and obese (OR, 1.34; 95% CI, 1.33-1.34) groups were more likely to have a normal cognitive function than a normal-weight group. Next, in the case of BMI categories of the WHO method, compared to a normal-weight group, underweight (OR, 1.15; 95% CI, 1.14-1.16) and overweight (OR, 1.06; 95% CI, 1.06-1.07) groups were more likely to have a normal cognitive function; however, obese (OR, 0.62; 95% CI, 0.61-0.63) group was less likely to have it. Lastly, in the case of the 10-group method, as BMI increased, the likelihood to have a normal cognitive function changed like a wave, reaching a global top at group-7 (26.5 kg/㎡ ≤ BMI <28.0 kg/㎡). Conclusion: The associations between BMI and cognitive function differed according to how BMI was categorized among people aged 45 and older in Korea, which suggests that cognitive function may be positively associated with BMI in some categories of BMI but negatively in its other categories. Health policies to reduce cognitive impairment need to consider this association between BMI and cognitive function.

Purpose: To evaluate physical characteristics, lifestyle related to bone-health, and bone mineral density (BMD) in mothers and their daughters and to determine the predictors of BMD. Method: BMDs at the forearm, lumbar spine, and femur were measured in 101 healthy, mother-daughter pairs by dual energy X-ray absorptiometry. Mother-daughter differences between general characteristics, means for BMDs were assessed by ${\chi}^2$-test, t-tests. Multiple regression analyses were used to identify predictors of BMD in each group. Results: Mothers had significantly higher BMD than their daughters at forearm, lumbar spine, and femur. The predictors of mothers' BMDs were body weight, body mass index (BMI) and percentage body fat, explaining 5.1~31.6% of the variation in BMDs. BMI, percentage body fat and their mother's BMD of the corresponding site bone were predictors in daughters, explaining 17.5~31.6% of the variations in BMDs. Conclusion: These results indicate the importance of weight on bone that the BMDs seems to be related to fat free mass both in young-adult daughters and in middle aged mothers. These also suggest the importance ofintervention for the development of BMD in daughter of mother with low BMD.

Purpose: The purpose of the study was to investigate factors that influence university women with eating problems. Methods: Study participants were 307 women from two universities. Self-report questionnaires which included items on eating problems, satisfaction with body shape, self-esteem, body mass index, and weight control methods were used. Data were analyzed using independent t-tests, ${\chi}^2$ tests, and a multiple binary logistic regression. Results: About 20% of the undergraduate women were experiencing eating problems. The problematic eating group showed more dissatisfaction with body shape than the normal eating group, and used more diets, fasting, diet-products, and uretics/laxatives to control body weight. Significant predictors for the problematic eating group were diets, diet-products, BMI, self-esteem and dissatisfaction with body shape. The strongest predictors were diets; risk for women university students who had been on a diet was 15 times higher than their counterparts. Conclusion: It is pertinent for health professionals to start intervention programs to educate university women with eating problems. The contents should include information on healthy weight control methods, improving satisfaction with body shape and self esteem, as well as creating social atmosphere about healthy body shape for women.

Objective : Obesity is associated with degenerative arthropathy giving stress on joints. It also amplifies loads of weight bearing joints by changing the gravity line of the body. Our aim is to investigate the correlation between obesity and lumbar lordosis in obese pre-menopausal Korean females. The hypothesis was tested that there is a correlation between obesity and lumbar lordosis. Methods : A cross-sectional evaluation of 44 Females (baseline age 30.77 ± 6.46) with BMI 31.53 ± 3.82 (kg/㎡) was done. Body composition was measured using bio-impedance analysis (BIA), and anthropometry was done by the same observer. A lateral whole spine X-ray was taken in standing position to measure the lumbar lordotic angle (LLA), Ferguson angle (FA) and lumbar gravity line (LGL). A Pearson correlation was used to measure the correlation between obesity and lumbar lordosis (SPSS 10.0 for windows). Results : Body mass index (BMI kg/㎡) had a negative relationship with LLA((equation omitted)=-0.469), FA((equation omitted) =-0.347) and LGL((equation omitted)=-0.389). Body fat rate had a negative relationship with LLA only(γ=-0.385). Waist circumference had a negative relationship with LLA((equation omitted)=-0.345) and LGL((equation omitted)=-0.346). WH ratio had no relationship with lumbar lordosis. Conclusion : These data show that obesity is related to mechanical structures, such as lumbar lordosis. BMI was the most useful index, which reflects a change of mechanical structure of lumbar, more than other variables in this study.

This study was to investigate the effect on weight control and changes in serum glucose, total protein , GPT, GOT , cholesterol, triglyceride, calcium, and phosphorus contents of seventeen overweight female college students during experimental periods [before grape diet(0 day-, after grape diet (3 day), after control diet(3 day), after normal diet(30 day)]. The mean weight, height , BMI, and Rohrer index of the subjects at the onset of the study was 58.91$\pm$5.22kg, 159.94$\pm$6.01cm, 22.96$\pm$1.17, and 20.06$\pm$1.48 respectively. During the study subjects, conducted grape diets, control diets, and normal diets to control their weight. They analyzed their changes in anthrophometric variables. The mean weight was significantly decreased from 58.29$\pm$7.85kg to 57.2$\pm$8.23kg after normal diet(p<0.05). Therefore BMI (body mass index) and Rohrer index was also significantly decreased after experimental periods. The analysis of dietary intake showed that the grape diet induced unbalanced low nutrient intake, but the intake of total calories and other nutrients were almost recovered their onset of the study during control and normal diets. The concentration of serum glucose, cholesterol, triglyceride GOT, and GTP were significantly(p<0.05) decreased and significantly(p<0.05) increased again during experimental periods. Calcium concentrations were not affected by grape diet, but phosphorus concentration was significantly reduced after grape and control diet.

This study was designed to evaluate the effect of the individual nutrition education for type 2 diabetes who participate the diabetes buffet. The subjects were 66 patients and divided into education (n=34) and control groups (n=32). The mean age of education and control groups were 59.8 and 56.6 years old, respectively. There were no differences in age and body mass index (BMI) between two groups. Initial glycosylated hemoglobin (HbA1c), post prandial plasma glucose (PP2), total plasma cholesterol, and blood pressure were not different between two groups. But fasting blood sugar (FBS) was higher in education group than in control group. On completion of the study, the education group showed significant decreases in body weight, BMI, FBS and PP2, however, the control group showed no changes in body weight, BMI and PP2, and showed a significant increase in FBS. Initial calorie and protein intakes of the education group did not meet the prescribed amount, however, mineral and vitamin intakes were higher than estimated average requirement (EAR). By the end of study, calorie and protein intakes were significantly increased to meet the prescription. In order to evaluate the effect of diet education, awareness of calorie requirement was used as an index of understanding diet prescription. The degree of awareness of calorie requirement was dependent on age: younger patients showed higher awareness than older subjects. The subject who showed better understanding of diet prescription showed lower levels of HbA1c, FBS, and PP2 at the end of the experiment period. The results of this study clearly show that individual diabetes diet education is effective to make the patient understand their diet prescription, and is effective to control body weight and blood sugar level. Awareness of calorie requirement could be used as an index of understanding of prescribed diet. Since age is an important variable to determine the awareness of calorie requirement, different strategies of nutrition education should be developed for different age groups, especially patients over 70 years old.

The purpose of this study was to investigate the nutritional status before and after gastrectomy of gastric cancer patients in Jeonbuk Province. The subjects were 136 patients with gastrectomy of gastric cancer. We assessed the nutritional status before and after an operation by general characteristics (age, clinicopathological stage, type of operation, method of reconstruction), anthropometric characteristics (height, weight, skeletal muscle mass, body fat mass, body mass index (BMI), percent body fat, arm muscle circumference AMC, arm circumference AC) and biochemical characteristics (hemoglobin Hb, hematocrit Hct, mein corpuscular volume MCV, mean corpuscular hemoglobin MCH, total lymphocyte count TLC, serum albumin, serum transferrin). Mean ages were 60.0 yrs in males and 58.8 yrs in females. Age, clinicopathological stage, types of operation and reconstruction methods were not significantly different between males and females. Weight, skeletal muscle mass, body fat mass, BMI, percent body fat, AMC and AC significantly deteriorated by gastrectomy. There were severe weight losses in males and females after gastrectomy. Hemoglobin, Hct, MCV, MCH, TLC, albumin and transferrin significantly deteriorated by gastrectomy. After gastrectomy, subjects who were assessed as malnounrished in Hb and Hct were increased in male and those who were assessed as malnounrished in Hb were increased in females. These results suggest that a nutrition intervention, specially for energy, protein and iron, is necessary to improve the nutritional status of gastric cancer patients with gastrectomy.

The purpose of the study was to investigate Body Mass Index (BMI), the perception of weight problem and the level of self-esteem and depression in high school and college females. The convenience sample consisted of 303 high school females and 481 college females. Data were collected between November 1999 and December 1999. Subjects ranged in age from 15 years and 26 years. BMI was calculated based on the subject's self-reported body weight and height. Self-perception of having a weight problem was evaluated by a single item question. The Rosenberg's Self-Esteem Scale and the Center for Epidemiologic Studies Depression Scale were utilized to measure the level of self-esteem and depression symptoms. BMI mean scores were 19.92 and 19.83 in high school females and college females, respectively. Based on BMI, 79.2 percent of high school females and 85.2 percent of college females were in a normal weight range. Only 2.6 percent of high school females and 1.5 percent college females were obese. Both high school and college females perceived their body weight problem as moderately severe. The mean scores of depression were 20.33 in high school females and 21.69 in college females. Sixty percent of high school females were depressed and 73.4 percent of college students. There was no significant difference between two groups in BMI. However, high school females perceived their weight problem more severe than college females. College females had higher levels of self-esteem and depression than high school females. BMI and perceptions of weight problem revealed a positive relationship in both groups. Results of the study revealed that a perception of weight problem contributed significantly to predict the level of self-esteem and depression in both groups. BMI score had significant effect on only college females' self-esteem. In the study, even though the mean score of BMI was in a normal range, subjects perceived their weight problems as moderatley severe. Since the perception of a weight problem influenced the level of self-esteem and depression, health care providers need to teach them about the normal weight range in BMI criteria.
