Development of a Questionnaire for Dietary Habit Survey of Korean Adults: Jin Suk Jo, Ki Nam Kim; Korean J Community Nutr 2014;19(3):258-273. Published online June 30, 2014; DOI: https://doi.org/10.5720/kjcn.2014.19.3.258

OBJECTIVES
The purposes of the study were to develop a questionnaire for dietary habit survey for Korean adults, and unify the terms related to dietary habits.
METHODS
The Delphi method by 43 professionals on dietary habit research was applied to unify the terms.
RESULTS
With regard to results on terms related to dietary habit, the respondents recorded the highest percentage (90.7%) of selecting the term "dietary habits" and also the highest percentage (76.7%) of choosing "dietary habits" for English. The biggest percentage of the respondents chose "individual dietary behaviors repeatedly formed and habitualized under the social, cultural, and psychological influence in the group" as the concept of dietary habits. The Delphi survey for the development of a questionnaire resulted in the first questionnaire of 31 items, the second one of 27 items, and the third one of 25 items. The validity of questionnaire items was tested with content validity ratios (CVR). The items whose CVR value was 0.29 or lower were eliminated or revised, because the minimum CVR value needed to test validity was 0.29. To test the reliability of questionnaire items, test-retest method was performed in 163 adults. According to the Kappa coefficient in the range of 0.314-0.716, all of the 25 items were in the reliability scope. A survey was taken with 702 adults to finally revise and supplement the third questionnaire whose validity and reliability were tested.
CONCLUSIONS
Through those processes, a questionnaire for adults' dietary habit survey was finally completed. The significance of the study lies in the development of the first questionnaire on dietary habits equipped with both validity and reliability in South Korea.

Effect of Nutrition Education and Exercise Intervention on Physical and Dietary Patterns of Some Obese Children: Myoung Sook Kim, Mee Sook Choi, Ki Nam Kim; Korean J Community Nutr 2011;16(4):426-438. Published online August 31, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.4.426

Abstract PDF PubReader

This study set out to investigate the effects of 16-week nutrition education and exercise intervention run by a public health center on the physical activities and dietary patterns of obese children at the before, after, and after one month point. After the program, the obese index of the obese children dropped by 5.9% from 38.4% to 32.5%. One month after the end of the program, their obese index increased by 1.4% to 33.9% (p < 0.001). The obese children's hours of walking of physical activities increased to 2.6 hours from 1.2 hours after the program and remained at the 2.6 hours range one month after the end of the program (p < 0.01). The total scores of their food habits increased to 10.4 points from 9.1 points after the program and 10.3 points one month after the end of the program with significant differences (p < 0.01). The total scores of their eating behavior made a significant increase to 6.5 points from 5.3 points after the program and then dropped to 5.9 points one month after the end of the program (p < 0.05). As for changes to their dietary pattern scores according to the obese index, only the food habits scores showed significant main effects of term (p < 0.05). According to these results, there is still a need to develop proper programs to help them increase regular exercise, improve their physical activities by cutting down time with TV, computer, Internet, and video games, and enhance their nutritional knowledge and to provide them with ongoing management and guidance until the improved food habits and eating behavior become part of their habits.

Changes in Food and Nutrient Intakes of College Students between 1999 and 2009: Han Byul Jang, Hwa Young Lee, Young Hee Han, Jeehye Song, Ki Nam Kim, Taisun Hyun; Korean J Community Nutr 2011;16(3):324-336. Published online June 30, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.3.324

Abstract PDF PubReader

The purpose of the study was to examine the changes of food and nutrient intakes of college students between 1999 and 2009. Dietary survey of 169 college students was conducted by a 24-hour recall method for three days in 2009. Food and nutrient intakes in 2009 were compared with the data from 106 students collected by the same methods in 1999. The intakes of cereals & grain products and vegetables in 2009 were lower than those of 1999, but the intakes of meats, eggs, milk & milk products, and manufactured food were higher. The intake of rice per person decreased greatly from 452.2 g in 1999 to 351.4 g in 2009 in males, and from 306.9 g to 237.2 g in females. While the intakes of protein, fat, thiamin, niacin, vitamin B6, phosphorus, potassium, zinc, and cholesterol were significantly higher, the intakes of dietary fiber were significantly lower in 2009 compared to 1999 both in males and females. The nutrients consumed less than the Recommended Intakes were vitamin A, riboflavin, vitamin C, and calcium in males and additionally folate, iron, and zinc in females in both 1999 and 2009. The ratio of carbohydrate, protein and fat as energy was 61 : 15 : 24 and 60 : 14 : 26 in 1999, and 54 : 16 : 30 and 56 : 15 : 29 in 2009 in males and females respectively, showing that carbohydrate intake decreased and fat intake increased greatly. Our data suggest that nutrition education is necessary for college students to help them consume more vegetables and fruits and less fat and cholesterol.

Research Trend of Nutrition through Analysis of Articles Published in 'Korean Journal of Community Nutrition': Jin Suk Jo, Kyoung Sin Lee, Ki Nam Kim; Korean J Community Nutr 2011;16(2):278-293. Published online April 30, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.2.278

Abstract PDF PubReader

The purpose of this study was to examine the research trend of nutrition for the recent 12 years from 1996 to 2007 by analyzing 734 articles published in the Korean Journal of Community Nutrition. The majority of the articles (61.4%) were classified as survey types in terms of data collection methods. Most of the subjects used in the articles were adults (28.8%), and the subject whose research has been increased at the highest rate was "patients". The most frequent keywords in the title of articles were "nutrient intake" (231times), "food service" (92times), "dietary habits" (69times), and "obesity" (69times). The keywords that have appeared more frequently with the years were "osteoporosis" (450.0%), "menopause" (350.0%) and "dietary attitudes" (208.3%). As for research interests, "nutrient intake" was dominant in the early stage of research while "disease", "dietary habits", "dietary attitudes" and "nutrition education" have increased in recent years. Some of the most common methods of nutrition assessment were "dietary intake" (41.2%), "anthropometric" (34.0%) and "biochemical test" (14.7%). The most common methods of dietary intake were "24-hours recall" (28.6%) and "dietary habits" (23.3%). The results of this study showed some biases in data collection methods, gender of the subjects, and study areas. Moreover, inconsistent terminologies, questionnaire contents, and measures were used for the researches on dietary behaviors, dietary habits, dietary attitudes, which made it difficult to compare their results for each research. Therefore, standardized research methods and terminologies need to be developed regarding dietary practices.

Effect of Nutritional Education and Exercise Intervention on Reducing and Maintaining Weight in Obese Women: Myoung Sook Kim, Mee Sook Choi, Ki Nam Kim; Korean J Community Nutr 2007;12(1):80-89. Published online February 28, 2007

Abstract PDF: This study was performed to investigate the effectiveness of nutritional education and exercise intervention on reduction and maintenance of weight. The subjects were 24 obese women whose body mass index (BMI) was over 25 kg/m(2). Nutritional education was performed once a week and swimming was done three times a week throughout this 12 week program. The subjects were recalled 1 month after the program was complete. Nutrient intakes were assessed by 24 hour recall method. Also food habits, dietary behaviors and nutritional knowledge were investigated by self-administered questionnaires before and after the weight control program and one month after completing the program. Height, weight, body composition and blood levels were measured before and after the weight control program and one month after completing the program. During the 12 weeks of the weight control program, body weight significantly decreased from an average of 69.7 kg to 65.8 kg and to 65.1kg after one month (p < 0.05). Body fat and BMI also significantly decreased (p < 0.01). Cholesterol and blood sugar levels decreased after 12 weeks and increased one month after completing the program. After taking nutritional education, the nutritional knowledge scores increased. Calcium intake significantly increased after completing the education and one month after completing the program (p < 0.01). Iron intake significantly decreased from an average of 12.1 g to 11.3 g after completing the program and increased to 15.5 g one month after completing the progrom (p < 0.001). We concluded that our nutritional education and exercise program was effective for reducing and maintaining weight.

Infant Feeding Practices and the Factors that Influence Feeding Practices among Women in Seoul and the Chungbuk Area: Ki Nam Kim, Tae Sun Hyun, Nam Mi Kang; Korean J Community Nutr 2003;8(3):288-301. Published online June 30, 2003

Abstract PDF: In order to obtain baseline data for the development of an educational program on breastfeeding, a survey was carried out to investigate infant feeding practices, the characteristics the subjects have in common, and the factors that influence the feeding methods among women in Seoul and the Chungbuk area. Subjects included 671 lactating mothers who visited public health centers or pediatric clinics between December 1999 and February 2000, and were interviewed using a questionnaire. The results were as follows : With respect to feeding methods, the incidence of breastfeeding, formula feeding, mixed feeding and formula feeding switched from breastfeeding was 20.6%, 29.8%, 11.6%, and 38.0%, respectively. With respect to the characteristics the subjects had in common, the incidence of women who planned their infants' feeding methods before pregnancy, during pregancy, and after delivery was 48.7%, 31.0%, and 20.3%, respectively. The incidence of women who started breastfeeding in the hospital after delivery was 38.8%. About seventy seven percet of the subjects had not previously attended an educational program on breastfeeding, and most of these wanted to participate in the future in an educational program to learn about breastfeeding. Some of the topics they were interested in were 'Nutritional Management for Sufficient Breast Milk' (60.3%), "Breast Care" (25.0%), and "Correct Nursing Positions" (9.8%). Most (88.2%) of the women who breastfeed suffered from physical discomforts including discomfort of the waist, and legs and discomfort due to cracked or sore nipples. "Insufficient breast milk" was the main reason for breastfeeding cessation or for switching to formula feeding. With respect to formula feeding practices, the main reasons for selecting a specific brand of formula were "the same brand the hospital used after delivery" (34.3%) and "an advertised brand" (23.3%). The strongest factor for promoting breastfeeding was "the support of husband or parents", next were "breastfeeding in the hospital after delivery" and "planning to breastfeed before pregnancy" in that order. The characteristics the subjects had in common relating to formula feeding were "mother's job", "high economic level", "Caesarian section" and "planning to breastfeed after delivery". In conclusion, it is recommended that breastfeeding be pro-moted, and educational programs be developed and offered as soon as possible to each group which had unfavorable attitudes toward breastfeeding. In addition, the monitoring and supervision of formula advertisements is required to protect consumers from the adverse effects of exaggerated advertising.

The Economic Benefits of Breastfeeding: Taisun Hyun, Ki Nam Kim, Nammi Kang, Eun Young Lim; Korean J Community Nutr 2002;7(6):863-871. Published online December 31, 2002

Abstract PDF: To compare the costs incurred by infant feeding between mothers who breastfed their infants and those who fed them infant formula, a questionnaire survey was carried out to 136 mothers living in Seoul, Cheongju and Chungju who breastfed and 199 mothers who formula-fed their infants. The cost of formula-feeding was estimated based on the expenditures for formula and feeding apparatus, and the time needed to wash bottles and prepare formula. The cost of breastfeeding was estimated based on the expenditures for food for the additional nutritional intake of these mothers. The mean cost of formula-feeding was 1,870,125won during the first year of the baby's life. The food cost for the additional nutritional intake of the breastfeeding mothers was 203,004 won per year. The extra medical cost for respiratory illnesses in the formula-fed group compared to the breastfed group was 62,920 won because the formula-fed infants required medical attention for respiratory illnesses more often than the breast-fed infants. Therefore, breastfeeding could save 1,730,041 won during the first year of an infant's life. We may have underestimated the cost savings from breastfeeding because we did not take into account the potentially decreased costs of fertility control and the health benefits for mothers, as well as the decreased usage of water and gas. Analyses showed that breastfeeding is not only nutritionally advantageous, but also economically advantageous for families and society.

A Survey on the Feeding Practices of Women for the Development of a Breastfeeding Education Program: Breastfeeding Knowledge and Breastfeeding Rates: Ki Nam Kim, Taisun Hyun, Nam Mi Kang; Korean J Community Nutr 2002;7(3):345-353. Published online June 30, 2002

Abstract PDF: A survey was carried out to investigate the breastfeeding knowledge, breastfeeding rates and related factors among women in Seoul and the Chungbuk area, in order to obtain baseline data for the development of an education program on breastfeeding. Subjects included 671 lactating mothers who visited public health or pediatric centers, between December, 1999 and February, 2000 and were interviewed using a questionnaire. The results are as follows: In the breastfeeding knowledge, most of the subjects (93.4%) knew correctly that 'breastfeeding is better for a baby's emotional development than formula feeding,' whereas only half of the subjects (51.7%) answered correctly the question on whether 'formula is more nutritious than breastmilk.' The breastfeeding rates were about 57%, 40%, 33% and 12%, respectively for baby's aged 1, 3, 6, and 12 months. These results showed that the breastfeeding rate rapidly decreased with the baby's age. Lower breastfeeding rates were associated with high educational level (college graduate and above), high income, mothers' employment, no experience of attending breastfeeding education programs, and no planning on breastfeeding prior to pregnancy. There was a significant relationship between the level of knowledge and breastfeeding practice; the higher the knowledge score, the higher the breastfeeding rate. In conclusion, an education program should be developed and offered for each low breastfeeding rate group, in order to promote breastfeeding.

Prenatal Breastfeeding Education and Infant Feeding Practices in Public Health Centers and Baby-Friendly Hospitals: Taisum Hyun, Eun Young Lim, Nammi Kang, Ki Nam Kim; Korean J Community Nutr 2001;6(4):678-685. Published online October 31, 2001

Abstract PDF: Although breastfeeding is recognized to be vital to the health and well-being of children and women, the rate of breastsfeeding among Korean women has continuously decreased. One barrier to breastfeeding has been identified to be associated with health care providers. Health care professionals do not give sufficient advice and encouragement, next do hospitals provide supportive environments for breastfeeding by separating infants from mothers or providing formula. The purpose of this study was to investigate prenatal breastfeeding education and infant feeding practices in public health centers and baby-friendly hospitals. A telephone survey was carried out on 57 public health centers located in the Seoul and Chungcheong areas and 13 baby-freindly hospitals from February to April in 2000. Among the public health centers, 43.8% offered periodic prenatal education for pregnant women who visited the centers. Most of them used leaflets or pamphlets developed by the Ministry of Health and Welfare or UNICEF. Twenty six percent of the public health centers developed their own educational materials. All of the 13 baby-friendly hospitals gave additional fluids to infants, did not allow mothers and infants to stay together 24 hours a day, and did not foster the establishment of breatfeeding support groups among the mothers. Most of the baby-friendly hospitals gave artificial teats, did not help mothers initiate breastfeeding within a half-hour of birth. Findings indicate that current practices even in the baby-friendly hospitals are not consistent with the '10 steps to success breastfeeding'. Therefore, deliberate efforts should be made to incorporate adequate breastfeeding education into prenatal program in both public health centers and hospitals, and create environments to support breastfeeding in hospitals, even in baby-friendly hospitals.

Content Analysis of the Questionnaires Used in Dietary Surveys: Ki Nam Kim, Ae Jung Kim, Eun Sook Park, Mee Kyung Woo, Bo Kyung Lee, Taisun Hyun; Korean J Community Nutr 2000;5(4):697-708. Published online December 31, 2000

Abstract PDF: The purpose of this study is to analyze the contents of the questionnaires used in dietary surveys and to evaluate each item in relation to the item construction strategy. Articles of which the contents were related to food, nutrition, diet, dietary behavior, and related areas. Published from 1997 to 1999 were searched fir and a total of 121 questionnaires were collected and analyzed. The questions in the questionnaires were classified into related areas and sub-areas. Among the keywords in the title of the articles, the term 'nutritional status'(or 'dietary intake status') was most frequently used. The terms such as dietary status, obesity, health, food habit, and dietary behavior were also frequency used. Major topics of the items in the questionnaires varied according to the life cycle of the subjects of the study. The topics most frequently asked in each lift cycle were as follows : overeating, snack, and food preference for preschool- and school-aged children ; anthropometry, weight control, and snack for middle and highschool students : meal skipping, smoking, and drinking for college students : disease, smoking, drinking, and exercise for adults : and smoking, drinking, disease and perceived health for the elderly. Inappropriate questions with complicated language, typographic and grammatic errors, unnecessary words, and negative questions were found. Therefore, care should be taken to construct each question so as to avoid possible misinterpretation. Also, a standardized questionnaire be developed for survey researchers.

Development of a Simple Screening Test for Identifying Korean Elderly at Risk of Undernutrition: Ki Nam Kim, Taisun Hyun, Joung Won Lee; Korean J Community Nutr 2000;5(3):475-483. Published online September 30, 2000

Abstract PDF: The develop a simple screening test for identifying Korean elderly at risk of undernutrition, the data of the health-related habits, dietary behaviors and nutrient intakes of the elderly in Chongju were analyzed. Two risk indicators, mean adequacy ratio (MAR) and the respondents perceived health, were used to detect the undernutrition risk of the elderly. In order to select a list of questions for the test, factors a affecting nutritional status and items investigated in previous nutrition surveys of the elderly were considered, and 21 questions were primarily selected. A multiple regression and stepwise regression analysis were used to take out the weak predictors of poor nutrient intake, and to give item weights to the strong predictors, and a list of 17 questions was finally adopted. To determine the cut-point of the test score, sensitivity, and positive predictive values were calculated. The Simple Screening Test developed in this study is a brief, easily scored tool to predict poor nutrient intake and the perceived health status of the elderly. The test may provide a basis of further comprehensive nutritional assessment or intervention planning, if necessary, for those who are diagnosed ad "high risk". The test, however, needs to be independently validated by other groups of individuals.

Published online August 31, 1998

Abstract PDF: The purposes of this study were to investigate the effects of drug use & the health-related habits(alcohol drinking, smoking and exercise) on the nutritional status of elderly. subjects were 362 free-living elderly aged over 65(male 131, female 231) in Chungbuk area. Interviews with questionaire on drug use, health-related habits, and nutrient intakes, anthropometric measurement and biochemical blood test were carried out from August to October in 1996. Energy intakes of the males who used drug were lower than those of males who did not use any drug, while energy intakes of the females who used drug were higher than those of females who did not. In biochemical indices, LDL-cholesterol level of the males who used drug was higher than that of males who did not have drug. serum triglycerides, VLDL-cholesterol and obesity degree(BMI & TS) of the females who used drug were higher than those of females who did not have drug. Alcohol drinking, smoking and exercise habits of the elderly who used drug had little effects on the nutrient intakes while those habits had considerable effects on biochemical indices and obesity degree. Among drug users, male drinkers showed higher triglycerides & HDL-cholesterol level, and female drinkers showed higher triglycerides and lower total cholesterol and LDL-cholesterol level, compared to non drinkers. Among female drug users, smokers showed lower body mass index(BMI) compared to non smokers. Males and females who had both drinking and smoking habits showed higher serum triglycerides and VLDL-cholesterol level. Especially females who had both drinking and smoking habits showed lower BMI & Tricep skinfold thickness compared to those who had netiher drinking nor smoking habits.

Drug Consumption and Nutritional Status of the Elderly in Chung-buk Area: III. Psychological Effect on Drug Consumption and Nutritional Status: Dong Yean Park, Kyung Hee Hanm, Ki Nam Kim; Korean J Community Nutr 1998;3(2):245-260. Published online May 31, 1998

Abstract PDF: The influences of depression and health anxieth on the elderly's drug use and nutritional status were evaluated by interviews with questionaire from August to October in 1996. One hundred and thirty-one male and 231 female elderly in Chung-buk area were the sample for this study. Men's depression score was 22.3 and 25.2 for women, respectively out of 27. Women showed a significantly higher score for depression and health anxiety than men. Gender, age, marital status, number of family, education, income, medical insurance, and mobility and region significantly affected the health anxiety score. The higher depression score the elderly had, the more frequently they took drugs. Conversely. the higher depression score the elderly had, the less frequently they took nutritional supplements. For women, the higher depression score the elderly had, the more they smoked. More depressed elderly showed a significantly smaller BMI compared to the less depressed ones. A negative correlationship existed between the depression score and the elderly's nutrient intakes, especially energy intake which showed a significant negative correlation. There were no significant differences between health anxiety score and nutrient intakes of men. Women who had a higher health anxiety score consumed more energy significantly. The depression score did not affect the elderly's blood biochemical indices. Women who had a low health anxiety score showed a significantly higher HDL-C level.

Drug Consumption and Nutritional Status of the Elderly in Chung-buk Area: II. Nutritional Status of Urban and Rural Elderly: Kyung Hee Han, dong Yean Park, Ki Nam Kim; Korean J Community Nutr 1998;3(2):228-244. Published online May 31, 1998

Abstract PDF: The nutritional status of 362 elderly men and women in Chung-bud area was evaluated in terms of their nutrient intakes, biochemical and anthrophometric measurements by interviews with questionnaires from August to October 1996. Mean intake of all nutrients except ascorbic acid did not meet the RDA for this sample. Protein, vit A, reboflavin, calcium were the most likely to be deficient on the basis of propotions of elderly consuming less than 75% of the RDA. The subjects nutrient intake was significantly affected by gender, marital status, number of family, family composition, educational level, pocket money, and region. Men in rural areas and women over 75 in urban areas were the most vulnerable groups with nutritional deficiency. According to serum biochemical indices, mean level of cholesterol, triglycerides, LDL, total protein, albumin and iron belonged to normal range but mean level of HDL showed below the normal range. More elderly men and women in urban areas showed a higher percentage of abormal level of cholesterol, triglycerides, LDL and HDL than those in rural areas. More elderly men and women in rural areas had abnormal levels of RBC, Hematocrit and hemoglobin compared to those in urban areas. Mean height and weight of elderly men was 161.4cm and 56.2Kg, respectively and 149.1cm and 50.5kg for women. The elderly in rural areas were taller than those in urban areas but had less weight, MAC, TSF, MAMC. Mean BMI of this sample belonged to normal range. However, the elderly in rural areas had a higher rate of underweight and lower for overweight than those in urban areas. The elderly in urban areas had higher blood pressure than those in rural areas.

Drug Consumption and Nutritional Status of the Elderly in Chung-Buk Area: I. Diseades and Drug Consumption: Kyung Hee Han, Ki Nam Kim, Dong Yean Park; Korean J Community Nutr 1998;3(1):76-93. Published online February 28, 1998

Abstract PDF: Three hundred sixty-two(male 131, female 231) elderly aged over 65 in Chungbuk area were interviewed to determine the disease states and drug usage patterns. The prebalence of disease was 78% and women reported more chronic diseases(83%) than men(71%). Elderly who live with spouse and have an occupation have a lower rate of disease. Average number of diseases of the elderly was 1.8+/-1.1, and women(2.1+/-1.3) have significantly higher average number of diseases than that of men(1.4+/-0.7). Also the elderly in urban areas(2.1+/-1.4) have significantly higher number of diseases than that of the elderly in rural areas(1.6+/-0.9). Arthritis, hypertension, cardiovascular and gastric diseases were the most frequently listed chronic diseases in order for both men and women. Anemia and fracture of bone were relatively higher in women than in men. Particularly, the arthritis of the urban elderly have a rate of 1.5 times higher than that of the rural elderly. Fifty-two percent of the elderly were currently using drugs ; among drug users 71.2% used prescription drugs and 20.5% used nonprescription drugs. The average number taken per person was 2.1+/-1.4 and there was no sex or age difference. However, the elderly in rural areas (2.7+/-1.7) consumed a significantly higher number of drugs than those in urban areas(1.7+/-0.7). The average number of prescription drugs taken was 2.0+/-1.4 while the average of nonprescription drugs taken was 1.3+/-0.6. Analgesics and antihypertensive drugs were most commonly used. Vitamin and analgesics were the most frequently used self-prescribed drugs. It was noted that potential adverse drug interaction by concominant drug consumption for arthritis and antihypensive drug, abuse of digestants and antiacid without treatment of the underlying disease, and misuse of quick-acting bowel medications were problematic for the elderly. In addition drugs used for the elderly have some adverse effect on the digestive system. The types and composition of drugs used by the elderly were identified and presented. Medication compliance was poor and 13.5% reported adverse reactions such as edema, heartburn, nausea, and difficulty with eating. Seventeen percent of the elderly obtained drugs arranged by those other than medical staff. Also, even among those elderly who obtained drugs prescribed by a doctor, 69.1% of subjects had not receive instruction about potential adverse reactions. These results suggest that nutritional problems related to drug usage might exist and so dietitians, either individually or as members of health teams, need to have a better understanding of drug-nutrient interaction and closer supervision, and drug information/education service should therefore be provided to prevent or minimize adverse drug reaction in elderly users of medication.

Nutritional Status of the Elderly Living in Cheongju - I. Health-Related Habits, Dietary Behaviors and Nutrient Intakes: Ki Nam Kim, Joung Won Lee, young Sook Park, Tai Sun Hyun; Korean J Community Nutr 1997;2(4):556-567. Published online October 31, 1997

Abstract PDF: The health-related habits dietary behaviors and nutrient intakes of the elderly living in Cheongju were investigated by interviews with a questionnaire from August to September in 1996. The responses of 169 free-living elderly aged over 65(male 91, female 78) were analyzed. Thirty-six percent of the subjects smoked currently, 33%, drank alcoholic beverages, and 52% exercise regularly. Exercise was mostly in the from of walking for 1/2-1 hour. Significantly higher proportions of males smoked, drank, and exercised as compared to females. Food groups eaten at every meal were examined on a 5-point scale, and the consumption scores were compared with groups according to sex, age, smoking, drinking, and exercise habits. The elderly who exercised regularly got significantly higher scores in their calcium intakes and the variety of the 6 food groups than the elderly who did not exercise. The dietary assessment data showed that the energy intakes of males and females were 81.9% and 72.8% of the RDAs, respectively. The proportions of the elderly consuming less than 75% of RDAs of vitamin A and calcium were 96.5% and 91.1% of the total subjects, respectively. Higher educational status, more pocket money and regular exercise had positive effects on nutrient intakes, while smoking and drinking among females, but not males, had negative effects. Therefore, to improve nutritional status of the elderly, intake of vitamin A-and calcium-rich food such as milk with regular exercise should be emphasized on the education program.

Nutritional Status of the Elderly Living in Cheongju - II. Anthropometric, Biochdemical and Clinical Assessment: Tai Sun Hyun, Ki Nam Kim; Korean J Community Nutr 1997;2(4):568-577. Published online October 31, 1997

Abstract PDF: To assess the nutritional and health status of the elderly, anthropometric measurements and blood test for analyzing biochemical indices were carried out from August to September in 1996. Data on the incidence of a specific disease and clinical symptoms were also collected by interviews with a questionnaire. Among the total of 169 free-living elderly interviewed(91 men, 78 women), 86 elderly(57 men, 29 women) participated in the anthropometric measurements, and 73 elderly(52 men, 21 women) in blood tests. Average heights and weights were much lower than the standards established in the Korean Recommended Dietary Allowances. While average triceps skinfold thickness of men and women were above the 50 percentile of the reference data, mid-arm muscle circumferences were lower than the 50 percentile. Prevalences of anemia, assessed by hemoglobin using WHO definition, were 38.5% for men and 33.3% for women. Blood levels of total protein and albumin were above the normal limit for all participants. Mean blood cholesterol levels of men and women were 163.9mg/dl and 185.8mg/dl, and triglyceride levels were 138.2mg/dl and 161.9mg/dl, respectively. Women older than 75 years generally had high levels of BMI, total cholesterol and triglyceride. Health status assessed by clinical symptoms generally showed no significant difference by age, and their smoking, and drinking habits. Males and the elderly who exercised regularly had better health status. It was suggested that exercise was a good way to improve health status.

Effects of Nutrition Education on Nutrition Knowledge, Dietary Attitudes, and Food Behavior of College Students: Kyoung sin Lee, Ki Nam Kim; Korean J Community Nutr 1997;2(1):86-93. Published online February 28, 1997

Abstract PDF: The purpose of this study was to investigate the effects of nutrition education on nutrition knowledge, dietary attitudes, and food behavior of college students. The subjects of this study were 350 college students attending a university. The education group students received nutrition education three hours per week during a 4-week period offered in a 'Home Economics' course. A total of 150 students in the education group and 200 students in the non-education group completed pre-test questionaires examining nutrition knowledge, dietary attitudes, and food behaviors. Major findings were as follows : nutrition knowledge, and food behavior of the education group were improved compared to the non-education group. But significant changes were not observed in dietary attitudes in the education group. There were higher correlations between nutrition knowledge and dietary attitudes score, and between dietary attitudes and food behavior score at the posttest than those at the pretest. These results suggest that nutrition education for college students can effectively improve their nutrition knowledge and food behaviors.
