This study was performed to investigate the factors related to vitamin & mineral supplement use by the adolescents. Nine hundred and seventy-two adolescent boys and girls attending middle or high schools were chosen from various cities and rural communities in Korea. In this study, the factors affecting vitamin & mineral supplement use were analyzed from a self-administered questionnaire. It was found that vitamin & mineral supplements were taken by 31.3% of subjects. High school students(p<.01), female girl students(p<.001), and rural-dwellers(p<.001) took vitamin & mineral supplements more frequently than their complementing groups. The socioeconomic status of the family (p<.01), and supplement consumption by parents and siblings respectively affected the supplement use by the subjects(p<.001). Vitamin·mineral supplements were consumed more often in subjects who perceived their health as poor(p<.001), skipped breakfast(p<.05), and received nutritional information from books or magazines(p<.05). However, food habits and nutritional knowledge score of subjects did not affect vitamin & mineral supplement use. These findings suggest that adolescents take vitamin & mineral supplements commonly, and they tend to use supplements without prescription. Vitamin·mineral supplement consumption seems to be affected by general characteristics, health related variables, and meal management attitudes of subjects. Therefore, nutritional understanding and education are required in regard to the used of vitamin & mineral supplements, and the relationship between balanced diet and good health for the adolescents.

This study is conducted in order to investigate the prevalence of vitamin mineral (VM) supplement use and its related factors among Korean adolescents. Using a cross-sectional study design, information was obtained by questionnaires from adolescents selected by stratified sampling in large, small and middle-size cities, as well as rural areas of the whole country, followed by convenience sampling. The total number of participants in this study was 1,407 adolescents ($15.2{\pm}1.6$ years) attending middle or high schools, chosen from various cities and rural areas in Korea. The prevalence of VM supplement use was 65.5%, and there was no significant difference between the genders. City dwellers took VM supplements more frequently than those adolescents from rural areas (p < 0.01). The VM supplement users tended to have higher family income, parents' academic background, and socioeconomic status, respectively (p < 0.001). The greater part of VM supplement users replied that they acquired their nutritional information from their parents, relatives and friends, while many nonusers replied that they did it from school classes (p < 0.05). Compared to nonusers, VM supplement users had greater 'self concern about health' (p < 0.05), 'parents' concern about child's health, growth, and nutritional intake' (p < 0.001), and 'parents' concern about child's grade point' (p < 0.01). However, there was no significant difference between users and nonusers when it came to 'self perception of body shape' or 'BMI'. In addition, users significantly had greater nutritional beliefs concerning VM supplements than nonusers (p < 0.001). These results showed that VM supplement use has been common among adolescents in Korea, and supplement use of subjects has been related with various factors. Among them, it was shown that especially parents great influence the use of VM supplements by adolescents. Thus, not only education for adolescents, but also that for parents is needed to help adolescents take VM supplements properly.

The purpose of this study was to investigate nutritional risk factors, perceptions on nutrition and health, nutritional knowledge, flood habits and their correlation to supplement use in middle-aged and elderly Koreans. A nationwide survey was conducted in the metropolitan areas (6 cities) and middle-sized cities (8 cities) of Korea from October to December, 2000. Subjects were randomly selected based on population, and 2,188 non-institutionalized adults aged over 50, and elderly (male 765, female 1,423) were studied. Data were collected using a standardized questionnaire administered in personal interviews. Nutrition and health-related scores of nutritional risk factors, perceptions on nutrition and health, nutritional knowledge, and flood habits were significantly higher in supplement users as compared to non-users. There was a negative correlation between nutritional risk factors and other nutrition and health-related scores on perceptions on nutrition and health, nutritional knowledge, flood habits, and pocket money. Also there was a positive correlation between nutritional risk factors and age. Therefore, these results may provide basic information for proper supplement use by middle-aged and elderly koreans.

Objectives: Although dietary supplements use in Korea has been rapidly increasing and women are more likely to take dietary supplements more than men, only a few studies have been conducted to investigate factors contributing to gender differences in dietary supplement use in the Korean population. The aim of this study is to evaluate the prevalence of dietary supplement use and also identify gender-specific key factors that contribute to it using the data of the 4th KNHANES. Methods: Subjects were divided into user and non-user groups according to the answer given to the question that asked whether they had used any dietary supplement for more than 2 weeks on a regular basis during the previous year. Factors related to dietary supplement use were examined by general characteristics, health behavior and eating behavior. Results: Prevalence of dietary supplement use was 13.6% for men and 20.6% for women. Users were more likely to be middle-aged, have higher income and education, have a spouse, or reside in dong areas in both men and women. Regarding health behaviors, men with desirable lifestyle behavior were more likely to take dietary supplements, while men who smoked were less likely to take dietary supplements. Regarding disease history, both men and women with a current disease had higher odds of taking supplements. With regard to dietary behavior, frequent eating out and nutrition attitude were associated with higher odds of taking supplements in both men and in women. Conclusions: Health or dietary behavior related factors that were associated with taking supplements differed by gender. These findings can be useful for planning gender-specific dietary education and health programs.

The Purpose of this study was to investigate the dietary intake of nutrients and the use of vitamin and mineral supplements by Korean college students attending Web class and the socioeconomic, dietary and health-related factors involved. The subjects were 137 male and 115 female students amending a health and nutrition-related Web class at a cycler university. This cross-sectional survey was conducted by self-administered questionnaire and the data were analyzed by SAS and SPSS PC package programs. Nutrient intake data collected using three-day recall method were analyzed by the Computer Aided Nutritional Analysis Program. Average intake by male students of most nutrients except energy, vitamin B$_2$ and calcium and intake by female students of those except energy, vitamin $B_2$, calcium and iron was higher than Korean RDA. Nutrient intake of male students was significantly influenced by the mother s job, skipping meals, exercise, vitamin and mineral supplement use, flood supplement use and self-evaluated anemia. Skipping meals and flood supplement use significantly influenced the nutrient intake of female students. A total of 47.4% of male students and 53.9% of female students were vitamin and mineral supplement users. In female students, socioeconomic characteristics such as the father s education level and household income were significantly different between vitamin and mineral supplement users and non-users. In both male and female students, there were significant differences in cross analysis between vitamin and mineral supplement use and flood supplement use. As for the self-reported health status of male and female students, vitamin and mineral supplement users perceived their health status to be worse compared to non-users. Therefore, nutrition education via the Internet is necessary in order to encourage college students to practice optimal nutrition strategies, including maintaining well-balanced diets by choosing various floods wisely.

This study was done to investigate the use of nutritional supplements (NS) in Korean elite soccer players using an anonymous questionnaire. NS were classified into health supplements, manufactured health food supplements, chinese medicines & tonic foods, and nutrient supplements. Information was sought on the type of NS and factors that might influence supplement use including selected demographic parameters and health related variables. The data were collected from 241 athletes (aged $24.6{\pm}3.8$ years) in 9 professional soccer club. The prevalence of NS use among the subjects was 81.3%. Health supplements were used most frequently and nutrient supplement drug was the second one. Among the health supplements, weight/muscle gainer and calorie replacement product were most frequently used. Vitamin supplements were most frequently used among all nutrient supplement drugs. Users of NS were higher age (p<0.05) duration of exercise (p<0.05), and income (p<0.05) than non-users. The married (p<0.05) and a member of K-league (p<0.01) tended to have higher prevalence of NS use. The main adviser of NS were family (55.3%) and oneself (39%) instead of coach or sports nutritionist. Although NS use, only 26.2% certainly check up nutritional information on their used NS. Among the subjects, 84.5% of them felt that NS use were improved athletic performance, and 86.5% of them will to keep on taking supplement. These data suggest that a large number of elite soccer players use NS and these players may require education about healthy nutritional supplement practice and on the proper use of nutritional supplements.

본 연구는 서울 일부지역 대학교에 재학중인 345명의 한국인 대학생 남녀를 대상으로 비타민 무기질 보충제 섭취실태 및 관련요인을 파악하고자 실시되었으며, 그 결과는 다음과 같다. 1. 전체조사대상자의 비타민 무기질 보충제 섭취율은 40.9%, 남학생의 섭취율은 40.2%, 여학생의 섭취율은 41.3%를 보였다. 2. 응답자들은 식품영양 전공자 인 경우 (p = 0.046), 그리고 가족들이 비타민 무기질 보충제를 섭취하고 있을수록 (p < 0.001) 비타민 무기질 보충제의 섭취율이 높았다. 3. 건강관련요인과 비타민 무기질 보충제 섭취와의 관계를 보면, 비흡연자 일수록 (p = 0.004), 현재 질병을 가지고 있을수록 (p = 0.039), 그리고 본인의 건강에 대한 관심이 높을수록 (p = 0.001) 조사대상자의 비타민 무기질 보충제 섭취율이 높았다. 4. 비타민 무기질 보충제 섭취군이 비섭취군보다 식사할 때 음식에 소금이나 간장을 더 넣지 않는 등 짜지 않게 먹는 식습관을 갖고 있었고 (p = 0.003) 다양한 음식을 섭취하는 것으로 나타나는 등 (p = 0.003) 전반적인 식생활 총점이 더 높은 것으로 나타났다 (p = 0.016). 5. 종합비타민제의 섭취율이 가장 높았고 (68.6%), 그 다음이 비타민 C제 (31.4%) > 칼슘제 (17.1%) > 종합비타민-무기질제 (10.7%) > 철분제 (9.3%)순으로 높게 나타났다. 비타민 C제 (p = 0.041)와 철분제 (p = 0.008)의 경우 여성의 섭취율이 남성에 비해 유의적으로 많음을 보였다. 하루에 섭취하고 있는 비타민 무기질 보충제의 개수에 있어서 67.9%가 한 종류를 섭취한다고 조사되었으나, 하루에 두 종류 이상의 복용자도 32.1%에 해당했다. 섭취기간은 한 달~6개월 미만 복용자가 46.0%로 가장 많았으며, 6개월~1년 미만 15.1%, 그리고 1년 이상 복용하고 있는 학생들도 7.9%를 나타냈다. 6. 보충제 섭취군은 비타민 무기질 보충제 성분의 효능에 대해 62.1%가 '조금 아는 편이다', 20.0% 는 '전혀 모른다'고 답하였고, 보충제 구입은 34.3%가 본인이 구매하고 있으며, 65.7%의 응답자는 대부분 가족 또는 부모님이 비타민 무기질 보충제를 구매하는 것으로 나타났다. 7. 보충제 섭취자들은 비타민 무기질 보충제 섭취 후 부작용을 경험하지 않았고 (97.9%), 섭취 후 개선점이 있는지에 관해 57.9%는 개선된 점이 없다고 답했으며, 앞으로의 복용계획에 대해서 계속 복용하겠다 라고 응답한 사람은 79.3%였다. 본 연구의 결과를 통해 본인의 건강에 대한 관심이 높을수록 비타민 무기질 보충제를 섭취하는 비율이 높았음을 알 수 있었고, 하루에 한 종류의 보충제를 섭취하는 비율이 가장 높았으나, 하루에 여러 종류의 비타민 무기질 보충제를 섭취하고 있는 대학생들도 있음을 알 수 있었다. 섭취되는 보충제의 종류는 종합비타민제가 가장 많았으며 그 다음으로 비타민 C가 높은 것으로 나타났다. 특히 비타민 C제와 철분제의 경우 여성의 섭취율이 남성보다 높게 나타났다. 또한, 건강한 식행동을 갖고 있는 조사대상자들의 영양보충제 섭취율이 더 높게 나타나서 실제로 다양한 음식으로부터 충분한 영양소를 섭취하고 있는 대상자들이 별도로 비타민 무기질 보충제를 섭취하고 있음을 파악할 수 있었다. 섭취자의 대다수가 복용 후 개선된 점이 없다고 응답하였으나, 앞으로도 계속해서 복용하겠다고 응답한 사람이 많았다. 식품을 통한 영양소 섭취가 충분함에도 불구하고, 보충제를 통한 영양소의 과다섭취가 장기간 지속될시 건강상에 위해한 영향을 미칠 수 있다. 뿐만 아니라, 본인이 섭취하고 있는 비타민 무기질 보충제의 효능에 대해서 정확히 아는 사람들이 적은 것을 감안할 때, 학생들을 대상으로 한 영양 보충제에 관한 지식전달이 미흡한 것으로 볼 수 있다. 가족의 섭취유무가 조사대상자의 비타민 무기질 보충제 섭취유무에 큰 영향을 미치고, 정보원은 대부분 가족 및 친지이며, 가족 및 부모님이 구매하는 경우가 많았기 때문에, 학생들을 대상으로 한 올바른 영양교육이 실시되어야 하겠다. 대학생들이 쉽게 접할 수 있는 영양교육 프로그램의 개발이 요구되며 학교 내 교양수업의 개설을 통해 교육의 기회가 제공되어야 할 것으로 사료된다.
