Purpose: During the recent decades, the age at menarche continued to decline in Korea and worldwide. Prior studies have suggested that early menarche may increase the risk of various social, psychological, and physical health problems in young adolescent girls, but little is known about the determinants associated with early menarche. The purpose of this study is to evaluate independent determinants of early menarche among 5th~6th female graders in South Korea. Methods: Our analysis was conducted in 95 menarcheal girls and 95 age-matched pre-menarcheal girls residing in Daegu, South Korea. Demographic and lifestyle characteristics were collected using survey questionnaires for children and parents. Dietary information was assessed by 2 day~24 hour food records and survey questionnaires, which were completed by both children and their parents. Anthropometric data were obtained from the student health check-ups at the school. Results: A multiple logistic regression analysis using a conditional likelihood method was performed for simultaneous evaluation of several risk factors. There were significant differences in that higher proportion of obesity (OR, odds ratio = 5.60, 95% CI, confidence interval = 1.34~23.42), shorter sleep duration (OR = 0.45, 95% CI = 0.23~0.87), and younger mother's age at menarche (OR = 0.64, 95% CI = 0.44~0.93) were observed in the menarcheal group compared to the pre-menarcheal group. Conclusion: These findings indicate a possible association of sleep duration, mother's menarcheal age, and obesity with age at menarche. A well-planned, prospective cohort study is warranted to examine causal relationship.
To figure out the causes of obesity against middle-aged women, this study aimed to provide basic data for setting an obesity-related policy through analysis on diverse related factors. Against the healthy middle-aged women who visited 'N' Hospital Health Center in Incheon from April to November 2014, anthropometric assessment, body composition test and abdominal fat distribution test were conducted using Fat-CT. They were carried out against 159 women who agreed with the purpose of the study, using BMD, Q-CT. According to Fat-CT, subcutaneous and visceral types accounted for 39% (76 women) and 61% (119 respondents) respectively. In terms of BMI, 'underweight ($18.5kg/m^2$)' and 'overweight ($25kg/m^2$ or above)' were 13 women (6.7%) and 60 women (30.8%) each with the average of $23.5{\pm}4.11kg/m^2$. Mean while, waist circumference, diastolic blood pressure, systolic blood pressure and neutral fat were statistically significant at the 5% significance level. As getting older, muscle weakness offsets increase in body weight with abdominal obesity. A group with low BMI should also be considered due to increase in waist circumference.

This study was conducted to investigate the effects of green tea or coffee consumption on the serum lipids profiles. This study analyzed data of 1,343 participants (753 males and 590 females) among the people who underwent medical check-up. The subjects were divided by three groups as pattern of green tea or coffee consumption. Anthropometric measurements, biochemical analysis and nutrient intake using a food frequency questionnaire were performed. There were no significant differences among groups in height, % body fat, waist circumference, and body mass index. There was no significant difference among groups in energy intake. Fat intake was significantly higher in green tea and coffee group than the control group in men subjects. The intakes of dietary Fe, vitamin A, $\beta$-carotene, and folate was the lowest in coffee group (p<0.05). The intakes of dietary fat was the highest in coffee group in male subjects (p<0.05). Serum concentrations of total cholesterol and LDL-cholesterol were green tea< control< coffee group in order by multivariate analysis after adjusting for confounding factors. The serum concentrations of total cholesterol and LDL-cholesterol were significantly lower in green tea group than coffee group by multivariate analysis after adjusting for confounding factors (p<0.05). However, there was no significant difference in the serum concentrations of total cholesterol and LDL-cholesterol between green tea and control group. These results suggest that green tea consumption didn't show positive effects in preventing hyperlipidemia but coffee consumption showed negative effects in hyperlipidemia.

The purpose of this study was to measure the serum lipid concentrations by gender and age, and to investigate the relationship between dietary behavior and serum lipid levels in Korean adults. The subjects consisted of 209 volunteers (121 men and 88 women) who visited a health promotion center. Their anthropometric and biochemical blood indices were measured, and data on lifestyles were obtained using structured questionnaires. The blood total cholesterol, LDL-cholesterol, and triglyceride concentrations increased significantly with age in women (p<0.01). The food habit score of men and women increased with age, and total food habit score was negatively correlated with BMI (p<0.05). The rate of skipping meals (p<0.001), overeating (p<0.05), eating instant food (p<0.001), and eating out (p<0.05) decreased significantly with age, and the intake rate of vegetables (p<0.001) and carbohydrates (p<0.05) significantly increased with it. The food intake frequency of 21 food items was also measured, and snacks (p<0.05), high fat foods (p<0.01) meats (p<0.05), and instant foods (p<0.01) were negatively correlated with HDL-cholesterol. Snacks (p<0.05) and high fat foods (p<0.01) were positively correlated with LDL-cholesterol. Snacks (p<0.05) and fats/oils (p<0.01) were positively correlated with triglycerides. These results suggest that the food habits and food intake frequency may be one of the important factors affecting serum lipid concentrations in Korean adults.

Objectives The purpose of this study is to find the influential clinical and physical characteristics which affect apnea-hypopnea index (AHI) in suspected obstructive sleep apnea (OSA) patients. Methods We evaluated the comprehensive factors including sleep related symptoms, clinical scales, medical history, substance use, and anthropometric data of the 119 participants who complained of the symptoms of OSA. All the participants underwent attended-full night laboratory polysomnography. The correlation and multiple regression analysis were conducted to find the influential and predictive factors of AHI. Results A multiple linear regression model 1 showed that higher AHI was associated with higher body mass index (BMI)(p < 0.001) and higher frequency of observed apnea (p = 0.002). In multiple linear regression model 2, AHI was associated with higher BMI (p < 0.001) and loudness of snoring (p = 0.018). Conclusions The present preliminary results suggest that BMI and observed apnea are most influential factors that affect AHI in suspected OSA patients. In the future study we will design the prediction formula for the OSA and AHI, which is useful in the clinical medical field.
Objectives : The purpose of this study was to analyze the relationship between the Cold-pattern and the quantitative index through the results of an anthropometric method and Bio Impedance Analysis (BIA) of the Haenyeo living in Jeju island. Furthermore, we will examine the effect of Cold-pattern on the quality of life. Methods : BIA indices were acquired directly from Inbody770 and questionnaires were collected by Gallup Korea professional surveyor through face to face interviews. Binary regression analysis and linear regression analysis were used to examine the association between collected data. Results : Total of 175 of people were participated in this study. First, we examined the difference of the indicators in the Cold-pattern group and the non-Cold pattern group by the average comparison of the anthropometry and BIA indices. Most of the non-Cold pattern group showed high quality of life, BIA and anthropometry. In the relationship between Cold-pattern and anthropometry and BIA indices, BMI and PA indices were found to affect the Cold-pattern on a group basis. As the BMI increased by $1kg/m^2$, probability of not being non-Cold pattern was 1.13 times. and as the PA increased by $1^{\circ}$, probability of not being non-Cold pattern was 2.4 times. In the case of EQ5D value, the quality of life of ${\beta}$ was increased by 0.08 in non-Cold pattern (p <.05), EQ5D VAS of ${\beta}$ was also increased by 10.05 (p <.05). Conclusions : This study showed that BMI and PA could be used as a clinical index to evaluate the Cold-pattern as a clinical indicator, and there is a difference in quality of life according to Cold-pattern.

Cardiovascular disease is a leading cause of death and disability and remains so in the future. The aim of this study was to detect the impact of a 6-month diet intervention on cardiovascular risk factors in postmenopausal Iranian women. It was a randomized controlled trial that carried out in the East Health Clinic in Ahvaz-Iran. This study started on June 2007 and was completed on May 2008. A total 64 healthy postmenopausal women recruited and randomly assigned to the intervention group (35) and control (29). Over the six months follow-up, the intervention group received five educational sessions (two face to face and three lecture discussion classes with slide demonstration) at the first month. These sessions were about menopause, cardiovascular disease and healthy diet. Every participant in the intervention group received one face to face education session at the $3^{rd}$ month, and also received a telephone call at the end of each month starting with the second month to remain on the diet. Pre-intervention and post-intervention anthropometric measurements, blood pressure, blood lipids and dietary intake were assessed. Data analyzed using the SPSS version 15. Descriptive (means and SD), univariate (paired-t test, Chi-Square and Independent T-test) and multivariate (GLM Repeated Measure) statistics were used. Participants in the diet group had significantly lower weight (-0.9 kg), body mass index (-0.4 $kg/m^2$), and fasting blood sugar (-4.5 mg/dl). The diet group significantly increased their daily intake of fiber (+2.3 g, P=0.05), decreased their intake of sodium (-28 mg, P=0.04), and consumption of fruit and vegetable ${\geq}$ 5 serving a day (80%, P=0.03) compared to the control group. Post menopausal women are at a greater risk for cardiovascular disease. Healthy diet using educational intervention can be an effective means of reducing cardiovascular risk in postmenopausal women.
Objectives: Being overweight or obese is central to metabolic syndrome, and these characteristics constitute dominant risk factors for chronic diseases. Although behavioral factors, including eating habits and sedentary lifestyles, are considered to be determinants of obesity, the specific childhood factors that contribute to this condition have not been clearly defined. Methods: The subjects consisted of 261 children aged 7- 9 years who were recruited from an elementary school during October 2003. Information was obtained from their parents using a questionnaire focused on eating behaviors and lifestyle factors, additional data were also collected via anthropometric measurements and biochemical examinations, including blood tests. Results: A total of 48 (18.4%) of the 261 children were overweight, and 34 (70.8%) had at least one other component of metabolic syndrome. Eating behaviors emerged as significant lifestyle-related risk factors for being overweight or obese. Those who engaged in overeating more than twice per week had three times the risk of being overweight (odds ratio [OR], 3.10, 95% confidence interval [CI], 1.39 to 6.92), and those who ate rapidly had three times the risk of being overweight (OR, 3.28; 95% CI, 1.68 to 6.41). Those who had fewer family meals (fewer than 2?3/month) had a nine times higher risk of being overweight than those who had family meals more frequently (at least 1/day) (OR, 9.51; 95% CI, 1.21 to 74.82). Conclusions: This study showed that being overweight or obese during preadolescence is associated with a higher risk of metabolic syndrome and is related to unhealthy eating behaviors. Thus, weight-control strategies and healthy eating behaviors should be developed early in life to reduce the risk for metabolic syndrome.
The main purposes of the nutrition and clinical surveys were to provide baseline information on the nutritional status of pre-school children in rural health demonstration project areas of the Korea Health Development Institute (KHDI) for nutrition guidance services for the MCH target group. The survey covered a total of 222 pre-school children and 135 mothers in Okgu Gun, Cholla Pukto Province from August 10 to August 17, 1979. The survey results are summarized as follows: 1) Family Environment Seventy percent of the households had more than three children, and the mean family sire was 6. Sixty-nine percent of the mothers and 47% of the fathers of the surveyed households were educated at or below the primary school level. The majority, 70% of the mothers, were aged between 20 years and 35 years. 2) Anthropometric Measurements and Hemoglobin Value 4.5% of the children were lower than 80% weight for age of the Korean standard, and 5.4% were lower than 85% arm circumference for age of the Jelliffe's standard resectively, and those were suffering from protein-energy malnutrition. Angular stomatitis were observed on 66.2% of the subjects. Mean hemoglobin value was 11.1g/100m1, and 44.2% of the subjects were categorized as anaemia. 3) Food and Nutrient Intake of animal foods was very low, ranging from 2.9 to 17%. Consumption of eggs was less than 2% of total food intake, and intake of legumes was also very scanty, between 0.8 to 3.7%. These data present evidence of very poor protein intake, quality as well as quantity. Energy intake of children was 60.0 to 64.4% of the recommended allowance, and mean protein intake only met 47.4% of the recommendation. Low intake of vitamins except thiamin were also found. 4) Mother's Nutrition Knowledge Eighty-five percent of the mothers were entirely ignorant regarding the 'five basic food group' which is most important fact on food and nutrition guidance. Mean knowledge score from 14 basic questions about food and nutrition was as low as 5.1. There was a significant positive correlation between mother's educational level and nutrition knowledge score. 5) Family Planning Variable There were significant correlation among maternal, family planning variables, and some of the nutritional and physical measurements. The study revealed that the mother's educational level and nutrition knowledge score are more crucial factors than the family planning variables on effecting food intakes on children. Recommendation : According to the results of the surveys, there were high incident rates of nutritional anaemia and angular stomatitis among pre-school children, and most of rural women had very limited knowledge about food and nutrition. As a main part of the health education activities, the community health workers should provide nutrition education to the village mothers to improve the nutrional status of young children in rural areas. Nutrional promotion at the primary health care level should be mainly based on appropriate nutrition education.
The Purpose of this study was to investigate physical conditions and related factors of 5th grade, in Korea. The number of students surveyed was 10.751 . School health records of 63 grade schools were used. The school health record of 5th grade contains results of physical examination from 1st grade to 5th grade and results of physical fitness assessment for 5th grade. A questionnaire was also administered to the student. 1) The proportion of mother who has a job was 29% of students surveyed. Since some of mothers were working at odd hour, it is hard to take care of student's meal and nutritional intake. The proportion of students who didn't eat breakfast everyday was 5.8% . Students who took medicine for health were 26% of total students surveyed. 2) Male students were taller than female students until 4 th grade. At 5 th grade, the mean height was 137.1cm for male students and 137.6cm for female students . At 5 th grade, the mean weight was 31.5kg for male students and 31.2kg for female students. The 10, 25, 50, 75.90 percentile of the total distribution was examined . By rising in grade, the height velocity was decreased for male student and increased for female students . The weight velocity was increased sharply for male and female students and the increasing velocity was larger in female than male students. Using heights and weights from 1st grade, BMI, RI, and RW were calculated. 3) The proportion of students who drank milk everyday was 49%, The \intake frequency of cookies, eggs, ice cream, chocolate were higher than the intake freguency of cheese, ham and soy bean milk
