This study tries to show the physical growth patterns and various adolescent characteristics by using longitudinal data for the height, weight, chest girth and sitting height of 1, 132 high school students in Seoul. And this study also tries to show what influencing factors on the physical growth of this aged population. The followings are the results. 1. The boys have their peak velocity of height when they are 12~13 years old. And the girls have when they are 10~11 years old. Peak velocity of weight for boys is at the age of 13~14. And for girls is at the age ofr11~12. Peak velocity of chest girth for boys is at the age of 12~13. And for girls is at the age of 11~12. Peak velocity of sitting height for boys is at the age of 13~14. And for girls is at the age of 11~13. So girls of this period grow more rapidly by around two years than boys. 2. The menarche of girls begins at the age of 12.4. So it begins 1.4 year before peak height velocity period. 3. Of life behavior boys contingency coefficient between essential time and height and weight is .5150 and .479 5, that between studying time and height and weight is .3344 and and .2912(In case of girls is .4735, .4321, .3247, .3134).

Variables affecting bone heath of growing children were analyzed among forty nine 10-12 year old elementary students in three rural regions of north west Chungnam area. Information on age of the parents, duration of breast feeding and birth weight were collected from the guardians of the participants and nutrient intake and diet quality were assessed by average of three-day food records of participants with the help of dietitians. Bone health status was measured by calceneal broadband ultrasound attenuation (BUA) using quantitative ultrasound (QUS). Results showed that anthropometic indexes and nutrient intake levels were not different between boys and girls. However, iron intake was significantly lower in girls than in boys. Girls after menarche showed lower intake levels for thiamin, riboflavin, pyridoxine and niacin than girls before menarche. z-scores of BMI were lower than -1 and higher than +1 showed shorter breast feeding period than others but the difference was statistically non-significant. Overall, the subjects did not consume enough s of calcium, vitamin C and folic acid. Zinc intake and BMI were the most significant factors affecting BUA by the results of backward elimination in multiple regression models. Phosphorous and beta-carotene intakes showed significant negative relation with BUA. This study showed that children living in the rural area of Chungnam need extra care to keep their health and nutrient intakes especially for the nutrients known to affect growth. Tailored nutrition education needs to be more focused on the improvement of bone health status of children.

The iron nutritional status of 328(20-70 years old) women in Seoul and Puyo areas was evaluated using a dietary information and a measurement of hematological indices. The serum iron was measured by Red Blood Cell(RBC), Hemoglobin(Hb), Hematocrit(Hct), Serum Iron(S-Fe), Total Iron Binding Capacity (TIBC), Transferrin Saturation(TS) and Serum Ferritin(SF) and was analyzed with the information obtained by interviews which included socio-demographic variables and the dietary pattern of the subjects. The mean Hb was 12.6 $\pm$ 1.21g/dl(Seoul : 12.4 $\pm$ 1.14g/dl, Puyo : 13.2 $\pm$ 1.28g/dl), Hct was 38.7 $\pm$ 3.84%(Seoul: 37.5 $\pm$ 3.28%, Puyo: 4.19 $\pm$ 3.48%), S-Fe was 76.8 $\pm$ 31.49ug/dl(Seoul: 68.8 $\pm$ 27.3ug/dl, Puyo: 78.8 $\pm$ 32.3ug/dl) and TIBC was 277.7 $\pm$ 86.15ug/dl(Seoul: 354.1 $\pm$ 129.8ug/dl, Puyo: 259.0 $\pm$ 59.55ug/dl). The mean Ts(%) was 30.9 $\pm$ 17.9% (Seoul: 21.7 $\pm$ 10.52%, Puyo: 33.2 $\pm$ 18.68%) and the level was significantly higher in Puyo women(p<0.05). The mean SF was 45.4 $\pm$ 46.21ng/ml(Seoul: 53.6 $\pm$ 50.21ng/ml, Puyo: 36.1 $\pm$ 39.83ng/ml). The Red Blood Cell(RBC) showed a negative correlation with age and Hb, Hct showed a negative correlation with education and income level. However TIBC showed a and total energy expenditure per day. Energy, protein, carbohydrate, iron and vit.C intake showed a positive correlation with Hb and Hct. In particular, heme iron showed a positive correlation with RBC and nonheme iron of Hb, income level and iron intake affected on the level of Hct. In Seoul women, the age of menarche affected on the level of TIBC, total energy expenditure affected on the level of Hct. In Seoul women, the age of menarche affected on the level of TIBC, total energy expenditure affected on the level of S-Fe.

Background: Gall bladder cancer (GBC) is highly fatal disease with poor prognosis, with a 5 year survival rate of <10%. It is relatively rare cancer worldwide; however it is the sixth cancer and second most common gastrointestinal tract cancer in Nepalese women. The study focused on associations of certain demographic, lifestyle, dietary, and reproductive factors with gall bladder cancer. Materials and Methods: We conducted a hospital-based matched case control study on newly diagnosed cases of primary GBC at BP Koirala Institute of Health Sciences and BP Koirala Memorial Cancer Hospital. Controls were healthy non-GBC relatives of cancer patients, matched for age, sex and marital status (in case of females) with cases at a ratio of 1:2. Data were collected between April 2012-April 2013 by semi structured interview from both cases and controls. Analyses were carried out with SPSS. Conditional logistic regression was used to find odds ratios and 95% confidence intervals for bivariate and multivariate analysis. Results: A total of 50 cases and 100 controls were enrolled in this study. On bivariate analysis, factors found to be significantly associated with gallbladder cancer were illiteracy (OR=3.29, CI=1.06-10.2), history of gallstone disease (OR=27.6, CI=6.57, 115.6), current smoker (OR=2.42, CI=1.005-5.86), early menarche <13 years (OR=2.64, CI=1.09-6.44), high parity more than 3 (OR=3.12, CI=1.25,7.72), and use of mustard oil (OR=3.63, CI=1.40, 9.40). A significant protective effect was seen with high consumption of fruits at least once a week (OR=0.101, CI=0.03-0.35). On multivariate analysis, history of gallstone disease, early menarche, current smoker and high consumption of fruits persisted as significant factors. Conclusions: History of gallstone disease, cigarette smoking and early menarche were associated with increased risk of gallbladder cancer while high consumption of fruits was found to have a protective effect.

Purpose : Recent reports pointed out that gonadotropin releasing hormone analogue (GnRHa) therapy alone is not so promising for improving adult height in precocious puberty. So, that we studied the growth promoting effect of combined therapy with GnRHa and growth hormone (GH) in early pubertal girls. Methods : Twenty three early pubertal girls ($9.73{\pm}1.59yr$) with predicted adult heights (PAH) below-2 standard deviation score (SDS) were included. They were divided into two groups as follows; Group I before menarche (n=19) and Group II after menarche (n=4). After combined therapy, various growth parameters were compared between two groups and between the before and after therapy. Results : Between the two groups before therapy, chronologic age (CA), growth velocity (GV), body mass index (BMI), target height (TH), PAH and serum insulin-like growth factor binding protein-3 were not different, but BA, height and difference between bone age (BA) and CA were significantly higher and insulin-like growth factor-1 (IGF-1) was marginally higher in group II. After therapy, BA still remained higher in group II, but other parameters were not different. In both groups, after therapy, the difference between BA and CA, the ratio of BA over CA, and GV were significantly decreased, but PAH, height SDS and BMI were significantly increased. Regarding IGF-1 level, a significant increase was noted in group I, but not in group II. Conclusion : With combined therapy of GnRHa and GH, PAH in early pubertal girls might be improved significantly and even approach TH. Among them, those who were before menarche might have greater potential for the height gain than those after menarche in view of IGF-1 changes during therapy.

Women have a greater incidence of coronary heart disease(CHD) after menopause. It relates to hormone imbalance-induced changes in known CHD risk factors, especially hyperlipidemia. Accordingly, once women are diagnosed, the rate of morbidity and mortality is greater than for men. Thus, preventive strategies are critical to improve the quality oflife in the later years for women. The purpose of ths study was to explore the difference of anthropometric, environmental factors and food behaviors between normocholesterolemia and hypercholesterolemia within postmenopausal women. The subjects were classified as normocholesterolemia and hypercholesterolemia based on the Guideline for Korean Hyperlipidemia. The results obtained are summarized as follows. The distributions of general characteristics such as age, family income, occupation status, age at menarche, and menopausal period were not significantly different between the normocholesterolemia group and hypercholesterolemia group. The anthropometric factors such as body mass index(BMI) and waist hip ratio(WHR) were not significantly different between the normocholesteroemia group and the hypercholesterolemia group but odds ratio of hypercholesterolemia group was higher than that of normocholesterolemia but not significant. Aerobic activity more than 1hours/day was significantly related to low serum cholesterol concentration. Eating behaviors related to regular meal time, regular breakfast habit, and slow meal speed were related to low serum cholesterol concentration. Eating the chicken without skin was significantly related to low serum cholesterol concentration. Our data indicate that desirable eating habit, aerobic activity more than 1hr/day are important factors of serum cholesterol concentrations in postmenopausal women. The result of this study provide information that is important in designing appropriate dietary guidelines for hypercholesterolemia in postmenopausal women.

Very little is known about the relation between isoflavone intake and menopausal symptoms in Korean woman To find the effects and correlations between these factors, questionnaires(maternal factors, menopausal symptoms) anthropometric measurement, 24hr dietary recalls, and urinary isoflavones analysis were conducted in 100 postmenopausal women residing in the Kyunggi-do rural area. The average age hight and weight of the subject were 61.5 years, 153.6 cm and 56.2kg. The average age at menarche, menopause, and menstrual cycle were 16.7 years, 47.2 years, 29.8 years, respectively. Most of the postmenopausal women experienced mildly menopausal symptoms. The mean calorie, protein and calcium intake were 1417.6 kcal(74.7% of the Korean RDA) 53.2 g(88.6% of the Korean RDA) and 454.0mg(65.6% of the Korean RDA) respectively. The ration of energy from carbohydrate, protein, and fat was 68: 15: 17 The average isoflavone intake from soy foods was 27.27 mg. The major food source of the isoflavone were soybeans and soybean curd. The average urinary isoflavone excretion was 2. 78nmol/mg Cr and showed significant positive correlation with isoflavone intake. Isoflavone intake from soy foods had a negative correlation with the severity of menopausal symptoms. Therefore, soy foods which contain isoflavone may have a protective effect on menopausal symptoms of women in Korea.

The purpose of this study was to investigate the relation between climacteric symptoms and intakes of various nutrients, phytoestrogens and foods in postmenopausal women. We conducted anthropometric measurements, questionnaire interview and 24hr dietary recall for 3 days in 128 postmenopausal women aged $49{\sim}64$. The subjects were divided into the two groups, NCMS(non climacteric symptoms group) and CMS(climacteric symptoms group), according to the severity of the climacteric symptoms. There were no significant difference in anthropometric measurements, maternal factors(menarche age, menopause age), subjective health status, frequency of exercise, smoking and drinking status between the two groups. The Mg and lignan precusor intakes of the NCMS group were significantly higher than those of the CMS group. Mg, lignan precusor, pulse and seed intakes had negative correlations with the severity of climacteric symptoms. From this study results, Mg, phytoestrogen(especially some lignan) and some food groups like as pulse and seeds may prevent and reduce climacteric symptoms in postmenopausal women.
