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.

연구배경: 최근 건강기능식품 섭취에 따른 의료비 절감효과에 대해 상이한 연구결과들이 제시되면서 논쟁이 불거졌다. 이에 따라 본 연구는 건강기능식품 섭취 여부가 의료비 지출에 미친 영향을 분석하고자 한다. 방법: 2019-2020년의 제2기 한국의료패널 자료에서 2년간 건강기능식품을 섭취한 군과 섭취하지 않은 군을 확인하고 이들의 일반적 특성 차이를 배제하고자 성향점수매칭기법을 통해 1:1 매칭 데이터를 추출하였으며 두 군의 연간 총 의료비를 비교하였다. 더불어 의료비 지출에 대한 건강기능식품 섭취 여부의 영향을 확인하기 위해 다변량 회귀분석(Proc Surveyreg)을 실시하였다. 결과: 건강기능식품 섭취군은 약 172만 원을, 미섭취군은 약 143만 원을 의료비로 지출하였다(p=0.0186). 다변량 회귀분석 결과, 섭취군이 미섭취군에 비해 약 26.15% 더 많은 의료비를 지출하는 것으로 확인되었다(p=0.0004). 결론: 건강기능식품 섭취가 의료비를 절감시킨다는 이전 연구들과 달리, 본 연구에서는 건강기능식품을 지속적으로 섭취하는 사람들이 의료서비스 지출이 더 큰 것으로 나타났다. 이는 건강기능식품 섭취가 질병 예방이나 의료비 절감의 관점보다는 건강에 관심 있는 사람들이 건강관리를 위해 취하는 행동임을 제시한 이전 연구들과 같은 맥락으로 해석될 수 있다. 그러나 의료패널 자료의 다양한 한계점으로 인해 주의 깊은 해석이 필요하다. 향후 개인수준의 코호트 자료를 활용한 인과성 규명이 필요하다.

The present study was carried out to investigate the effects of magnesium supplement levels and periods on lipid metabolism in male Sprague-Dawley rats given low protein and magnesium deficient diets. The effect of magnesium supplement levels and periods on lipid metabolism in rats given a low protein and magnesium deficient diet for 2 weeks were investigated. Serum total lipid and triglyceride contents were significantly lower in magnesium supplement group compared with magnesium deficient group. Serum HDL-cholesterol/total cholesterol ratio was significantly increased as magnesium supplement level was increased. Liver total lipid, triglyceride, total cholesterol and phospholipid contents were significantly lower in magnesium supplement group than those in magnesium deficient group. Serum ALP, GOT and GPT activities were significantly decreased in magnesium supplement group compared with magnesium deficient group. In summary, the effect of magnesium supplement on lipid metabolism and enzyme activities were significant and we can see that magnesium supplement level propered to be requirement level(400 mg/kg diet)in the other cases except serum lipid contents.

In order to investigate supplement use in middle-aged and elderly outpatients suffering from age-related diseases over the last year, a cross-sectional survey was conducted from July to December 2001. The subjects were 1702 (male 731, female 971) age-related disease outpatients over age 50. Data was collected using a standardized questionnaire and in-person interviews. The prevalence of supplement use and the different categories of supplements taken by the subjects were examined using SPSS statistical package. Supplements were used by 48.9% of the subjects. The mean number of kinds of dietary supplements taken by subjects was 1.7. Chinese medicine was the most commonly used supplements in both the male and female subjects. Among the reasons for using supplements, health promotion ranked as the most common. Most of the supplement users, however, did not know or only knew roughly about the health claims of their supplements. Subjects reported the information source on supplements as family, friends or relatives followed by doctors or pharmacists. These results may provide basic information for proper supplement use among Korean middle-aged and elderly outpatients with age-related diseases.

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.

There has been little data on the prevalence of supplement use and the characteristics of the dietary supplement users in the Republic of Korea. This study presents the prevalence and the details of any dietary supplement use and the characteristics of the adults who use dietary supplements in the Republic of Korea. Between May 18 and June 16, 2006, nationwide and population-weighted personal interviews with 6,201 adult aged from 30 to 69 years were conducted and the final sample consisted of 3,000 people with a 49.8% response rate. We examined the prevalence and details of the use of dietary supplements and the characteristics of those who use the dietary supplement among adults. About sixty two percent of adults had taken any dietary supplement during the previous 12-month period in 2006. The most commonly reported dietary supplement was ginseng, followed by multivitamins, glucosamine, probiotics, and vitamin C. Female (versus male), an older age group, a higher family income, those living in metropolitan cities, those with marital experience, those with a higher level of education, and those having medical problems had a greater likelihood of reporting the use of any dietary supplements. The particular relationships differed depending on the type of supplement. The most Korean adults took one more dietary supplement and the dietary supplement users had different demographic and health characteristics compared to those of the nonusers. Research on diet supplements by the medical community is needed in the future.

Vitamin mineral supplement usage by self-prescription is popular behavior among adolescents. This study was conducted to investigate the behaviors of vitamin·mineral supplement usage and the relationship between demographic variables and supplement usage by healthy adolescents. Nine hundred seventy two boys and girls, aged 13-18 years, attending general middle or high schools were chosen from various cities and rural communities in Korea. As a result, vitamin·]mineral supplements were taken by 31.3% of subjects. Users tended to take vitamin·mineral supplements more frequently when they were healthy than when they suffered from disease. The taking period of supplements was different according to school type such as middle or high school(p<.05), sex(p<.001) and residence of subjects(p<.01). The main information source of supplements was newspaper/magazine/TV, and it was affected by sex(p<.05) and residence(p<.01). Vitamin·mineral supplements were generally recommended by their mothers instead of health professionals. The commonly cited taking reason of supplements was affected by sex(p<.01)and socioeconomic status of family(p<.05). The frequently responded effect obtained from supplement use was recovery from fatigue and it was different according to sex(p<.01). The major mentioned reason of not taking vitamin·mineral supplements by non-users was 'I eat a balanced diet'. The most frequently consumed supplements were vitamin C, followed by multi-vitamins supplements, and this pattern was different according to school type(p<.001), sex(p<.01) and residence(p<.05). These findings show that the behaviors of vitamin·mineral supplement usage by subjects are not resonable, and their supplement usage tends to be affected by demographic variables. Therefore, nutritional understanding and education that are intended to form the resonable behaviors toward vitamin·mineral supplement usage of adolescents should be provided with considering the relationship between demographic variables and supplement usage.

The global nutraceuticals market continues to grow due to rising income levels, increasing life expectancy, and a growing interest in personal health. Especially after the COVID-19 pandemic, the market for nutraceuticals has expanded rapidly with positive perceptions driven by increased attention to immune management for disease prevention. However, there is still a lack of research on the relationship between nutraceuticals and consumer behavior. This study aims to provide new insights into the dietary supplement market and help establish marketing strategies by analyzing consumer behavior toward dietary supplements in the post-COVID-19 era, focusing on Generation MZ. An online survey was conducted among consumers who have purchased dietary supplement products to test the hypotheses. The collected data were analyzed for validity and reliability using SPSS and AMOS programs. The results showed that the taste, price, brand, and design of dietary supplements significantly positively affect the satisfaction of MZ consumers. This study provides an in-depth understanding of the mechanisms of consumer behavior toward dietary supplements in the post-COVID-19 era, focusing on Generation MZ. By offering insights into consumers' health concerns and consumption behaviors, this study provides valuable perspectives on the future development of the market and helps companies develop effective strategies to meet consumer needs.
