Use of Dietary Supplements and Determinants of Taking Dietary Supplements by Gender in the Korean Population: Using the 4(th) Korean National Health and Nutrition Examination Survey (2007-2009): Yun Jung Lee, Minji Kang, Hee Young Paik, YoonJu Song; Korean J Community Nutr 2017;22(4):347-355.

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.

Abstract PDF: This study examined the status of current nutrition labelling and claims for the processed foods that were purchased in the supermarket. They were assessed in the aspects of frequency and content of nutrition labelling and claims. The results are summarized as follows; The percentage of products contain the nutrition labelling or claims of processed foods of investigation were 18.7% and 18.8% respectively. In the nutrition labelling method, the format separated by expression contents with 'only liability indication nutrient' or 'liability indication nutrients plus discretion indication nutrients' were 44.7% and 43.4% respectively. In the case of type and title, 'table' and 'nutrition composition' were used most frequently, 83.9% and 83.2% respectively. And in the case of expression unit, 'per 100 g or 100 ml' was higher (56.8%) than others. Nutrition claims were divided into 'nutrition content claim' and 'comparative claim', in the former the most claim was 'containing' and in the other 'more or plus' used most frequently. 'Nutrient function claim' was 13.4% and 'Implied nutrient claim' was 7.3% of all the claims. Results of the evaluation of current nutrition labeling system, nutrition labelling was less advanced and variable in content and format and also the information was not easy for consumers to understand and use them. To support achievement of the nutrition label, there must be program and initiatives for better understanding and communication and guidances on food labelling and nutrition for food manufactures.
