This study was due to investigate the dietary intakes, serum lipids and other hematological indices in female adolescent smokers. The subjects were 85 smokers, whose average pack-year(smoking years on the basis of one pack of cigarettes per day) was 1.26 and 87 nonsmokers who were female high school students in Seoul. An anthropometric measreument was performed and % body fat was also analyzed by the Bioelectrical Impedance Fatness Analyzer(GIF-891). Dietary intakes and food habits were examined through questionnaires and nutrient intakes were analyzed by the Computer Aided. Nutritional analysis program for professional(CAN-pro). Serum TG, HDL-cholesterol and total-cholesterol levels were measured with test kits. Serum glucose, albumin, GOT and GPT were measured by automated dry chemistry system, SPOTCHEM 4410. Hemoglobin, hematocrit, RBC, WBC and MCV were determined by Semi Automated Microcell Counter(F-520). All data were statistically analyzed by SAS PC package program. There was no significant difference in the anthropometric measurements between smokers and nonsmokers. The caloric intake in adolescent smokers tended to be higher than that of nonsmokers but the difference was not statistically significant. In addition, there was no significant difference between smokers and nonsmokers in biochemical indices. Analysis of serum lipids showed that the serum levels of total-cholesterol and LDL-cholesterol of nonsmokers were unexpectedly significantly higher(p<0.05) than those of smokers. Overall results indicate that smoking itself with short pack-year in healthy female adolescent did not seem to influence apparent health and nutritional status.
The purpose of this study was to examine changes in energy and macronutrient intakes during the premenstrual(days -10-1) and postmenstrual(days 5-14) phases. Thirty-two college female students recorded their food consumption and dietary patterns over 5 weeks from September 8 to October 12, 1997. Mean daily energy and macronutrient intakes and the percentage of energy intake from protein and carbohydrate were relatively consistent over the two menstrual cycle phases, but the energy intake from fat increased 1%(P<0.05)during the postmenstrual phase. Two different dietary patterns were identified by the shifts in energy intake between postmenstrual and premenstrual phases. Seventy five percent of subjects revealed a consistent pattern with the results of previous studies investigating food intake over the menstrual cycle, in which the premenstrual phase is associated with an increment in energy, carbohydrate, and protein intake. In contrast, energy, protein, and fat intakes increased during the postmenstrual phase in 25% of the subjects. We conclude that cyclical fluctuations in energy and macronutrient intakes occur in both postmenstrual and premenstrual dietary pattern groups across the two menstrual phased with the opposite directions.
In order to investigate the dietary intakes and physical characteristics in college women smokers, interviews using questionnaires were done on 33 smokers and 42 nonsmokers residing in seoul area. General living habits, dietary habits, food consumption frequency and nutrient intake by quick estimation were investigated through direct interviews with subjects. Subjects height, weight and blood pressure were measured, and body fat percentage were statistically analyzed using Bio-electrical Impedence Fatness Analyzer(GIF-891). All data were statistically analyzed by SAS PC package program ; percentage or mean and standard error were examined for each item, and the significant difference was evaluated by chi-square test or Student's t-test at $\alpha$=0.05. In the analysis of taste and food preference, smokers consumed larger amount of alcohol and coffee than nonsmokers ; they also disliked sweet taste. The results of food consumption frequency data also showed that smokers consumed less fish, milk and fruits but consumed more instant foods than nonsmokers. As a result of anthropometric measurements, height, age, and 패요 fat percentage showed no difference, but there was a significant difference in weight, BMI, systolic blood pressure, and diastolic blood pressure. Energy intake in nonsmokers was 1640 ㎉/day(CHO : Pro : Fat=66.0 : 14.7 : 19.3), in smokers. Intakes of calcium, iron, vitamin C, vitamin A, vitamin B1, vitamin B2, and niacin in smokers were not significantly different from those of nonsmokers.
This study was performed to investigate the adequacy of dietary fat and protein intakes among female college students. Daily intakes of energy, fat, protein, major amino acids and other nutrients were measured in 52 female college students. Daily energy intake was 75.8% of the recommended intake. Fat and protein consist 19.2% and 16.7% of the total calorie, respectively. The average protein consumption per day was 105% of the recommended intake. Essential amino acids intakes were more than the recommended amounts which appears in the 6th edition of Recommended Dietary Allowances for Koreans. However, when the intake of each essential amino acid was compared to the recommended amino acid requirement pattern, these subjects did not meet the estimated requirements. There was a highly significant correlation between daily protein intake and lipid intake implying the major sources of protein in the diet were also major sources of fat. Daily intakes of dietary fiber, vitamin C, iron, and phosphorous were above the recommended levels of intake. However, blood hemoglobin concentration was marginal indicating dietary iron consumption is not a good marker for iron status. Also, calcium intake was only 63.5% of the recommended intake. Therefore, these results imply that main problems for these subjects are low energy consumption, low calcium intake, and the quality of protein. However, as opposed to the hypothesis, the main energy sources were not the food items high in saturated fats such as instant foods, which should be emphasized further.
We aimed to evaluate the effect of nutrition education program on nutrition knowledge, dietary behavior, dietary intakes and anthropometric parameters in primary school children. Eighty five 4th grade children (boys = 43, girls = 42) were enrolled in the intervention program for 5 months. The subjects were asked to fill out a questionnaire about nutrition knowledge and dietary behavior two times, at the baseline and after completion of the program. Dietary intake information was collected from participants using a 3-day food record and their anthropometric parameters were measured. Upon completion of the intervention program, both nutrition knowledge and dietary behavior scores were significantly improved in all subjects. Energy intake was increased from 1,571.9 kcal to 1,734.1 kcal with significant improvements in nutrient density for protein, Ca, P, K, vitamin A and niacin. While subjects' height, weight, lean body mass and soft lean mass were significantly increased during the program, significant decreases were observed in the rohrer index, percent body fat, waist-hip ratio and body fat mass. The changes in nutrition knowledge scores were positively correlated with the changes in dietary behavior scores, micronutrient intakes and anthropometric parameters. These results indicate that enhancement of nutrition knowledge through well-planned long-term nutrition education program is effective not only for the improvement of dietary behaviors and dietary intakes but also for the positive changes in anthropometric parameters among primary school children.
Objectives: This study was conducted to examine the effects of nutrition education with a dietary guidebook for children on dietary attitude, nutrition knowledge and nutrient intakes. Methods: The subjects were 54 higher grade elementary students (27 educated vs. 27 non-educated). The educated group was provided individual and/or group lessons (40 min/lesson/week, 4 week) using a dietary guidebook of Children developed by The Korean Society of Community Nutrition (KSCN) & Korean Food and Drug Administration (KFDA). The contents were Balanced Diet, Smart Food Choices, Cooking a Healthy Snack and Building a Healthy Body. We examined the differences in nutrition knowledge, dietary attitudes and dietary intake between the educated group and non-educated group. Results: After education, the educated group improved dietary attitude, nutrition knowledge and qualitative nutrient intakes compared to the non-educated group. Specifically, among dietary attitudes, 'taking a meal with salty and spicy food' increased, while among nutrition knowledge, 'functions of protein', 'functions of fat', 'foods with carbohydrates', 'foods with fat', 'foods with vitamins', and 'foods with minerals' were increased. Nutrition adequacy ratio (NAR) scores for vitamin C, iron, and zinc were increased. Conclusions: Nutrition education using a dietary guidebook for children developed by the KSCN & KFDA had positive effects on nutrition knowledge and qualitative nutrient intakes. These findings suggest that nutrition education focused on personalized daily energy and nutrient requirements may improve dietary attitude and quantitative nutrient intakes of children.
To evaluate nutrient intakes of the first generation Korean -Americans in Hawaii, a dietary survey was conducted using a food frquency questionaire which included 139 food items most often consumed among Korean foods and American foods. The questionnaire surveyed 157 first generation Korean-Americans living in Hawaii. The 66.7~81.1% of first generation Korean-Americans in Hawaii were of healthy weight. The mean percentages of calories obtained from their dietary analyses were 61% carbohydrate, 23% fat and 16% protein. The calorie distribution of their diet appeared to be similiar between older women and older men, however it was seen that men consumed a higher percent of calories from fat than women among younger subjects. The mean dietary intakes for first generation Korean-Americans exceeded recommended intakes for protein, thiamin, niacin , vitamin A, vitamin C, folacin , phosphorus and iron , but the intakes of energy, riboflavin, vitamin B6 ,vitamin E, calcium and zinc were lower than the recommended dietary allowance for Americans. Compared with other groups based on age and gender , younger men had significantly(p<0.05) higher intakes of riboflavin, phosohrous, iron and zinc, and lower intake of folacin. Older subjects consumed significantly (p<0.05) less protein, riboflavin, vitamin B6 and zinc than did younger subjects, and most of the first generation Korean-Americans in Hawaii consumed adequate levels of saturated fatty acid . The ratio , however, of polyunsaturated fatty acid to saturated fatty acid in the diet of younger men was about 0.61, much lower than the recommeded ration of 1.0 and also was significantly (p<0.05) lower than that of other subjects. Moreover, cholesterol intakes of younger men were close th the maximum recommeded level of 300mg/day.

Objectives: We aimed to evaluate dietary intake among female breast cancer survivors in a cross-sectional study. Methods: A total of 127 women who had breast cancer surgery at least 6 months before baseline were included. Dietary intake of female breast cancer survivors was assessed through self-reported 3 day-dietary records. To compare dietary intake between breast cancer survivors and general female population without cancer, we selected the 1:4 age matched women from the 2011 Korean National Health and Nutrition Examination Survey (KNHANES). In the KNHANES, participants were asked about their dietary intake using the 24-hour dietary recalls. We also examined whether dietary intake varied by age group, cancer stage, or time since surgery among breast cancer survivors. We used the generalized linear model to compare their dietary intakes. Results: Intakes of total energy, beta-carotene, folate, vitamin C, plant iron and fruits were lower among breast cancer survivors with longer time since surgery compared to those with shorter time (p<0.05). Breast cancer patients with higher stage at diagnosis tended to consume less legumes (p=0.01) than those with lower stage. When we compared dietary intake between breast cancer survivors and the general female population without cancer, breast cancer survivors were more likely to consume most of macro- and micro-nutrients in larger quantity (p<0.05) and adhere to healthier diet characterized by higher intakes of legumes, seed and nuts, vegetables and fishes and shells than the general female population who never had been diagnosed with cancer (p<0.05). Conclusions: Our study results suggested that the intakes of nutrients and foods varied by time since surgery and cancer stage among breast cancer survivors and dietary intakes among breast cancer survivors differed from that in the general population. Further prospective studies are warranted to explore the association between dietary intakes of specific food items and survival among Korean breast cancer survivors.

To assess the relationship between serum cholesterol level and dietary intake in obese children, 50 subjects were selected as an obese group and 50 subjects as a normal group depending upon body mass index. Fasting blood samples were obtained and analyzed for serum total cholesterol(TC), high density lipoprotein cholesterol(HDLC), low density lipoprotein cholesterol(LDLC) and triglyceride(TG). The dietary intake and information on dietary behavior and family environment were obtained by questionaire using 24 hour dietary recall method for 2-consecutive days. The concentrations of TC, LDLC, HDLC and TG of obese group were estimated to be 193.3mg/dl, 122.5mg/dl, 53.7mg/dl and 86.0mg/dl, respectively. The obese group showed higher TC, LDLC, TG level(p<0.001) and lower HDLC level(p<0.001) than normal group. Food intakes in obese group were similar to those of normal group except meats & fishes(P<0.01), milk & dairy products, fruits(p<0.05), and green & yellow vegetables(p<0.001). Nutrient intakes in obese group exceeded Korean recommended dietary allowance for the corresponding ages. Saturated fatty acid(p<0.05) and cholesterol(p<0.001) intakes in obese group were higher than those of normal group. In correlation analysis, meats & fishes, eggs and milk & dairy products intakes were positively related to serum TC, LDLC and TG ; on the contrary, green & yellow vegetables and fruits intakes were negatively related to serum TC, LDLC and TG ; but positively to HDLC. Obesity index, serum cholesterol level, cholesterol and saturated fatty acid intake were positively correlated with parent's obesity index, frequency of snack per day, eating rate and late snack.
Epidemiological studies have indicated that a relationship between overweight and cardiovascular disease exists. To assess the relationship of unfavorable changes in serum lipid concentrations, apolipoprotein B, lipoprotein(a), blood sugar and blood pressure to anthropometric variables, nutrient intakes and dietary behavior,64 obese children were chosen as subjects and 24-hour dietary intake, dietary behavior as well as blood pressure, apolipoprotein B, lipoprotein(a), three kinds of cholesterol concentrations were measured in November 1976. More than half(57.8%) of the children had serum cholesterol concentrations over 175mg/d1, and 26.6% of them had over 200mg/d1 and this group could be classified as a high risk group. Abdominal obesity as measured with waist circumference and waist hip ratio was negatively co..elated to high density lipop개tein(HDL) cholesterol. Dietary behavior rather than nutrient intakes appeared to have associations with unfavorable lipid profiles. Total dietary behavior scores and fish and bean product consumption had strong correlations with potentially atherogenic lipoprotein concentrations. This study suggests that fir the early prevention of cardiovascular disease, waist hip ratio together with obese rate should be included in selective programs to identify risk group of children in Korea. furthermore, interventions in cardiovascular disease risk groups in obese children should emphasize maintenance of ideal body weight through reducing body fat and adopting desirable dietary behaviors such as increasing intake of fish or bean products.
