Purpose: The purpose of the study was to develop an emotional self-regulation program for obese children and to examine the program's effectiveness on depression, eating habits, and body mass index. Methods: The emotional self-regulation program was developed from theory-based strategies and a pre-post pilot study was conducted with 46 children (19: intervention, 27: control). The program included 6 weekly group sessions over 2 months. The embedded experimental model of concurrent mixed methods was used to better understand research outcomes by converging both quantitative and qualitative data. Anthropometric measurements and surveys were performed before and after the intervention. Three focus group interviews were conducted with all participants after intervention to explore their experiences. Results: The intervention group displayed decreased depression levels in the quantitative outcomes. The participants also expressed positive outcomes such as improvements in confidence, impulse management, intimacy, happiness, and losing weight. Conclusion: These findings suggest that emotional self-regulation skills are crucial factors for obese children not only to manage their emotional problems but also to control their weight. Further research is needed with a larger sample size and randomized controlled trials.

Background: Lipid accumulation product (LAP) is associated with the presence and severity of nonalcoholic fatty liver disease (NAFLD) in adults. Purpose: Here we evaluated the ability of LAP to predict NAFLD in obese children. Methods: Eighty obese children (38 girls; age 6-18 years) were included. Anthropometric measurements and biochemical values were obtained from the patients' medical records. LAP was calculated as [waist circumference (WC) (cm) - 58]×triglycerides (mmol/L) in girls; [WC (cm) - 65]×triglycerides (mmol/L) in boys. The minLAP and adjLAP were described (3% and 50% of WC values, respectively) and the total/high-density lipoprotein cholesterol index (TC/HDL-C) was calculated. NAFLD was observed on ultrasound, and patients were divided into 3 groups by steatosis grade (normal, grade 0; mild, grade 1; moderate-severe, grade 2-3). The area under the curve (AUC) and appropriate index cutoff points were calculated by receiver operator characteristic analysis. Results: LAP was positively correlated with puberty stage (rho=0.409; P<0.001), fasting insulin (rho= 0.507; P<0.001), homeostasis model assessment of insulin resistance (rho=0.470; P<0.001), uric acid (rho=0.522; P<0.001), and TC/HDL-C (rho=0.494; P<0.001) and negatively correlated with HDL-C (rho=-3.833; P<0.001). LAP values could be used to diagnose hepatosteatosis (AUC=0.698; P=0.002). The LAP, adjLAP, and minLAP cutoff values were 42.7 (P=0.002), 40.05 (P=0.003), and 53.47 (P= 0.08), respectively. For LAP, the differences between the normal and mild groups (P=0.035) and the normal and moderate-severe groups were statistically significant (P=0.037), whereas the difference between the mild and moderate-severe groups was not (P>0.005). There was a statistically significant difference between the normal and mild groups for adjLAP (P=0.043) but not between the other groups (P>0.005). There was no significant intergroup difference in minLAP (P>0.005). Conclusion: LAP is a powerful and easy tool to predict NAFLD in childhood. If LAP is ≥42.7, NAFLD should be suspected. This is the first study to assess LAP diagnostic accuracy for childhood obesity.

Bone mass accretion during puberty appears to be critical in the development of peak bone mass. Although bone density of females in Korea has been studied, only a few studies have related bone mass with anthropometric patterns or puberty in the pubescent girls. This study was conducted as part of a study of major determinants of bone development during puberty. Subjects were aged 14∼16 yr(mean 14.97), and had no history of disorders or dedication use likely to influence bone or calcium metabolism. Bone mineral density and content were measured by dual energy X-ray absorptiometry using a Lunar DPX+Scanner (Lunar Madison, WI). Also, total body fat, and total lean body mass were assessed using a Lunar DPX dual-energy X-ray absorptiometer, Pubertal status was assessed according to the Marshall and Tanner guidelines. Serum levels of osteocalcin was measured by RIA using a commercial kit assay. Skinfold measurements were taken with a skinfold caliper(Lange Caliper, USA). Data were analyzed using the regression and GLM procedure of the statistical package SAS. The results indicated that the observed means for lumbar spine BMD and femoral BMD correspond to approximately 91% and 96% of the means for young adult females, respec tively. All subjects were menarchal, with the majority being in the middle to end stages of pubertal development. Total body BMD was positively related to fat mass(P<0.001), lean body mass and time since menarche, and negatively related to urine pyridinoline, serum alkaline phosphatase and osteocalcin. The data indicate that girls who reported lower age for menarche had significantly higher bone densities than girls who reported higher age for menarche. Attaining peak skeletal bone mass during puberty may reduce the incidence of osteoporosis in later life. this finding suggests that early menarche may augment peak bone mass, influencing the extent of bone loss later in adulthood. The results suggest that good nutrition in childhood appears to be needed not for growth and development, but possibly also to assure an optimal peak of bone mass and thus greater latitude for the maintenance or skeletal integrity in the face of bone losses. Troeps skinfold thickness was a better predictor of total BMD and total BMC than was any other skinfold thickness. The study did not find a relationship between total BMD and body fat %, but total fat was significantly positively related to total BMD(r=0.49) and total BMC(r=0.60). It supports earlier report that there was a significant correlation between TBMD and body weight. Conclusively, total fat, lean body mass and pubertal development could influence BMD in pubescent girls. Clearly, longitudinal studies are required to assess the effect of puberty on peak bone mass, and to define further the potential determinants of peak bone mass.

The purpose of this study was to compare the nutrient intake and diet quality of postmenopausal osteoporotic women to those of control subjects, and to investigate the relationship among diet quality and bone mineral density in postmenopausal women. In this study, we classified the subjects into the postmenopausal osteoporotic women (n =38) and control (n = 43) according to their lumbar spine bone mineral density and age. Dietary intakes, anthropometric measurements and dietary quality indices were measured and evaluated. The average age of osteoporotic and control group were 60.4 yrs and 58.3 yrs, respectively and there was no significant difference. Body weight, body mass index of osteoporotic group were significantly lower than those of control group. The average energy intake of osteoporotic and control group were 1243.3 kcal and 1475.8 kcal, respectively and there was a significant difference. The osteoporotic group consumed significantly lower quantities of protein, plant protein, vitamin A, vitamin $B_1,\;vitamin\;B_2$, folate, vitamin C, calcium, animal calcium, plant calcium, iron and zinc compared to the control group. The osteoporotic group consumed significantly lower of food, vegetables, mushrooms, fruits intakes compared to the control group. In the diet quality, protein, vitamin A, vitamin $B_1,\;vitamin\;B_2$, folate, vitamin C, calcium, iron, Zinc nutrient adequacy ratio (NAR) of osteoporotic group were significantly lower than that of control group. Mean adequacy ratio (MAR) of osteoporotic and control group were 0.63 and 0.78, respectively and there was significant difference. To evaluate nutrient density, Index of nutritional quality (INQ) was calculated by dividing nutrient content per 1,000 kcal of diet with RDA per 1,000 kcal. The average dietary variety score (DVS) of osteoporotic and control group were 22.4 and 33.2, respectively and there was significant difference. DVSs of pulses (p<0.01), seeds (p<0.01) and vegetables (p<0.05) in osteoporotic group were significantly lower than those of the control. In conclusion, postmenopausal osteoporotic women had lower protein, vitamin A, folate, vitamin C, calcium, iron zinc intake quality and vegetables, mushrooms, fruits DVSs than those of the control. Therefore, to promote skeletal health enough energy and food should be consumed, and the maintenance of vitamin and mineral balance by increasing of vitamin A, folate, vitamin C, calcium, iron of intakes are very important.

This study was conducted to evaluate the health status of elderly women who attended in a Health Promotion Program of the Seo-gu Health Center in Daegu. The study subjects were 158 elderly women (over 65 years) in an urban community. The subjects were investigated by means of individual interviews using a questionnaire, Blood tests for analyzing their biochemical status were carried out. The average age of the study subjects was 70.9 $\pm$ 2.3 years. Of the subject group 79.1% ranged in age from 65 to 74 year and 20.9% were over 75 years. With respect to health related factors, 23.4% of subjects drank alcoholic beverages and 15.2% of subjects currently smoke.The prevalence with chronic diseases was 51.9%, and 26.6% of the subjects were healthy. The diseases most frequently reported as having been or being treated were arthritis (38.1%), hypertension (21.4%), and diabetes (17.9%). The average height of subjects was below the standard established in the Korean Recommended Dietary Allowances, while the average weight was close to the standard. The means of systolic and diastolic blood pressure were 130.2 mmHg and 71.9 mmHg, respectively. The mean serum albumin level was 4.5 mg/d$\ell$ and the value of hemoglobin and hematocrit was 12.5 mg/d$\ell$ and 0.7%, respectively. The mean serum cholesterol level was 207.1 mg/d$\ell$ and the mean triglyceride level was 187.7 mg/d$\ell$. The serum lipid levels were higher then in those reported in research. The serum cholesterol levels of 71.5% of subjects were within the normal range. The GOT and GTP levels were within the moderate range. In conclusion, the health status of the elderly who attended the Health Promotion Program in the Seo-gu Health Center were very average. However, it was necessary to prepare a health management program to deal with the serum lipids so as to establish and maintain good health. When we carry out the health promotion program in a community, individual program Of adequate to health status should be developed more.

To investigate the effects of isoflavone supplementation on both bone mineral density and hormone variation in premenopausal women who had decreased bone mass, the 24 subjects were divided into two groups: one was the underweight group, consisting of 13 subjects, and the other was the normal weight group consisting of 11 subjects. For each group, we investigated the effects of isoflavone supplementation of 90 mg/day on both bone mineral density and hormone variation during 3 menstrual cycles. Anthropometric measurements, dietary recall, and analyses of blood and urine were assessed from baseline to post-treatment. The results were as follows: The average age of the underweight group was 21.8 years old and that of the normal weight group was 23.2 years old. The comparative results for the two groups at baseline were as follows: Onset of menarche, menstrual cycle, and menstrual length were not significantly different between the groups. Serum protein, total, HDL-, LDL-cholesterol, triglyceride, Ca, P, Mg, Cu, and Zn level were not significantly different between the groups. Serum estradiol, SHBG, LH, and FSH level were also not significantly different between the groups. Lumbar spine BMD by T scores of the underweight group was significantly lower than that of the normal weight group. Serum osteocalcin, urinary DPD, and urinary pH were not significantly different between the groups. The comparative results for the two groups at post-treatment were as follows: From baseline to post-treatment, the intake of energy, nutrients and isoflavone in food did not significantly change in either group. Serum protein, total cholesterol, HDL-, LDL-cholesterol, and triglyceride levels did not significantly change in either group. Serum Ca, Cu, and Zn levels were significantly lower in both groups and serum Mg level significantly decreased only in the underweight group. Serum estradiol levels were significantly lower in both groups, but serum SHBG, LH, and FSH levels did not significantly change in either group. Lumbar spine BMD by T score of the underweight group significantly increased to 15%, but that of the normal weight group did not significantly change. Serum osteocalcin of the underweight group significantly increased to 28%, while that of the normal weight group significantly increased to 40%. Urinary DPD of the normal weight group significantly increased to 12%. The results show that the BMD of the underweight group was lower than that of the normal weight group. Therefore, the underweight group had a disadvantage in obtaining maximum bone mineral density. The results also show that isoflavone supplementation during 3 menstrual cycles was effective in increasing the bone mineral density of the lumbar spine and affected bone metabolism markers in premenopausal underweight women. Therefore, it can be concluded that sufficient intake of isoflavone could be helpful in preventing decreases in bone mass among premenopausal women, especially underweight women.

There is some evidence that soy isoflavone has beneficial effects on the concentration of blood lipids. In this study, we investigated habitual isoflavone intake levels and the relation among dietary isoflavone intake, blood pressure, and blood lipids of adult men (n = 149) and women (n = 205). Anthropometric measurements including blood pressure, dietary in-take assessment using 24-hour recall method, and biochemical assessment using blood were conducted. The average age, height, weight, and BMI were 54.7 years, 168.5 cm, 67.3 kg, and 24.5 $kg/m^2$ for men and 53.9 years, 153.8 cm, 59.2 kg, and 25.0 $kg/m^2$ for women, respectively. The mean daily intakes of total food and energy were 1219.1 g and 1740.9 kcal for men and 1071.3 g and 1432.6 kcal for women, respectively. The mean daily isoflavones (daidzein + genistein) intake of men and women were 20.0 mg and 14.2 mg, respectively. Blood pressure of the subjects was 128.3/75.5 mmHg for men and 124.1/73.7 mmHg for women. Serum lipids of men and women were 180.2 and 184.9 mg/dL for total cholesterol, 160.8 and 137.6 mg/dL for triglyceride, 41.5 and 44.7 mg/dL for HDL-cholesterol, 106.6 and 112.7 mg/dL for LDL-cholesterol, and 3.5 and 3.3 for atherogenic index, respectively. Serum triglyceride and atherogenic index of men were significantly higher than those of women. In men, isoflavone intake and the level of total serum cholesterol were negatively (p < 0.05) correlated, after adjusted age. In women, there were significant correlations between isoflavone intake and blood pressure (systolic and diastolic), after adjusted age (p < 0.05). Based on these results, we concluded that higher isoflavone intake seemed to be related to a better lipid profile in men and lower blood pressure in women. But more epidemiological studies and controlled clinical trials would help to confirm the optimal amount required for the prevention and treatment of cardiovascular disease.

This study was conducted to investigate the prevalence of metabolic syndrome(MS) and characteristics of nutrient intake in MS subjects by gender and age. The subjects were 957(447 men and 510 women) who visited medical center for regular medical check-up. The diagnosis of MS subjects was adapted from NCEP-ATPIII with blood glucose, cholesterol, triglycerides, and blood pressure and Aisa-Pacific definition with waist-circumference. Anthropometric and biochemical measurements were practiced, then the nutrient intake analysis was assessed through the 24-hour recall method. The MS prevalence of all subjects was 10.3% in average -17% in men and 4.5% in women, respectively. The energy intake in MS group was 2,047.1 kcal and 1,699.5 kcal for normal group, showing significantly higher in MS compared to normal subjects. For intakes of animal fat, cholesterol, and sodium, MS group were significantly higher than normal group. In respect of gender, men subjects of MS group showed significantly higher nutrient intakes than normal group for energy, fat, and cholesterol. Women subjects of MS group showed higher intakes for energy, carbohydrate, and protein. For 30s, MS group showed higher intakes of energy, animal fat, and cholesterol than normal group. Fat and cholesterol for 40s and energy, carbohydrate, vegetable fat for 50s, MS group showed significantly higher intakes than normal group. In summary, MS group showed higher intakes of energy, animal fat, cholesterol, and sodium than normal group.

The LAP (lipid accumulation product) index is an indicator of excessive fat accumulation in combination with the fasting triglyceride concentration and waist circumference. This study examined the relationship between the LAP index and ALT (alanine aminotransferase) level and the effect of the LAP index on the ALT level. Cross-sectional studies were conducted on healthy adult males without a history of liver disease. From January 2015 to June 2017, 13,854 adults between 20 and 70 years of age, who underwent health screening at a general hospital in Gyeonggi-do, were enrolled in this study. The LAP index was calculated as [waist circumference (cm)-65]${\times}$[triglyceride (mmol/L)] for males. Serum ALT abnormalities were set at 40 IU/L or more in males. All subjects underwent measurements of the anthropometric indicators and physiological examinations. A significant increase in ALT with increasing LAP quintiles was observed (p<0.001). The LAP index correlated with ALT (r=0.238, p<0.001). Insulin (r=0.449, p<0.001) and HDL-cholesterol (r=-0.369, p<0.001) were strongly correlated with LAP. In addition, the LAP index is a factor affecting the ALT level (p<0.001). As the LAP index increased, the risk of an elevated ALT was higher (p<0.001). In conclusion, the LAP index was a predictor of an ALT elevation in Korean men.
