Abstract PDF: This study was performed to compare nutritional supplementation habits for Korean professional soccer players with those for the non-athletic male adults. Information about prevalence and kinds of supplements taken, information sources, nutrition knowledge were collected. Data were obtained from 53 football players working for Korean professional football clubs and 44 non-athletic males, who answered a list of questionnaires which had been prepared in advance. The prevalence of supplement use in the soccer player group (96%) was strikingly higher than in the nonathletic male group (34%). Vitamins were taken most frequently, followed by red ginseng, multivitamin, Chinese medicine and amino acids supplements in the soccer player group, with each player taking 2.96 kinds of supplements in average. Multivitamin was the most popular supplement in the non-athletic male group. The major reason for taking supplements was not to feel and recover from fatigue in both groups. It appeared that the non-athletic males started to use supplements mostly by recommendation of friends or colleagues. Meanwhile, soccer players took supplements on their needs, with half of them (50.1%) provided with nutrition information. The most important information source was coaches for soccer players group, and mass media for the non-athletic male group. The average scores of soccer players group on basic nutrition and athletic nutrition were lower than the respective values of the non-athletic males. Among the soccer players, 68% had taken more than 3 kinds of supplements during the last year; nonetheless, more than half could not perceive the effectiveness of the supplements. Our results show that supplementation practices were widespread in soccer players, and suggest that nutrition education for proper use of supplements and overall health care is needed for soccer players.

Published online October 31, 2002

Abstract PDF: The purpose of this study was to investigate the regional differences in dietary supplement use and related factors among college students participating in nutritional education programs via the internet. The subjects in this study were 797 college students (male: 518, female: 279). A cross-sectional survey was conducted using a self-administered questionnaire about dietary supplement use, demographic characteristics, health-related lifestyles, nutrient intake, and data were collected via the internet and by mail. Dietary supplements were taken by 82.2% of subjects (males: 76.3%, females: 85.3%). There was a significant regional difference in supplement use (p < 0.01). The supplements, used most frequent by male students in the Seoul and Incheon areas were lactic acid beverages and gagogi, in that order. Male students in the Kyunggi area used gagogi and lactic acid beverages in that order. Lactic acid beverages and Chinese medicine were used most frequently by male students in the Chungcheong area. Male students in the Kyungsang area used lactic acid beverages and water-soluble vitamins, in that order. Male students in Seoul and Kyungsang areas showed significantly higher percentage of keep on taking supplements compared to other areas (p < 0.05). Both male and female students in the Seoul area had more frequent medical examinations, in comparison to students in other areas (p < 0.05). Male students in the Kyungsang and Seoul areas took significantly more calcium (p < 0.05) and iron (p < 0.05), in comparison to students in other areas. Female students in the Kyunsang area took significantly more Vitamin A, phosphorous and iron (p < 0.05), while those in the Seoul area took significantly more Vitamin C (p < 0.01) and calcium (p < 0.05). Male students in the Chungcheong area took significantly less seaweed, in comparison to students in other areas (p < 0.05). Male students in the Seoul area had the highest amount of animal fat and oil, while those in the Incheon area ate the lowest amount of animal oil and fat (p < 0.05). Female students in the Kyunggi area ate the highest amount of fruit, while those in the Incheon area ate the lowest amount of fruit (p < 0.05). Female students in the Incheon area ate the highest amount of seaweed, while those in the Kyunggi area ate the lowest amount of seaweed (p < 0.01). Therefore, it can be concluded that it is necessary to develop dietary supplements to optimize the nutritional status of college students in different areas of Korea.

Published online April 30, 2002

Abstract PDF: 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.
