ABSTRACT
Objectives:
This study investigates dietary supplement intakes by examining the characteristics of dietary and health-related behaviors. Data were obtained from the Korea National Health and Nutrition Examination Survey (KNHANES). Dietary and health-related behaviors were also examined before and after the occurrence of COVID-19 and household types (multi-members vs. single person).Methods:
Data used in this study were collected from the 2019-2020 KNHANES by including adults aged 19 to 64 years. Pregnant, lactating, and subjects consuming calories less than 500 and more than 5,000 were excluded. Differences in dietary and health-related behaviors before and after COVID-19, and between the two types of households were analyzed by Chi-square analyses using Rao-Scott. Logistic regression analyses were applied to determine which dietary and health-related behaviors affected the dietary supplement intakes. In addition, descriptive analysis was run for demographic characteristics.Results:
The dietary supplement intake rate differed significantly with respect to the gender, age, education, marital status, and household income. Dietary supplement intakes, frequency of eating out, obesity, and body weight changes were significantly different before and after COVID-19. In addition, meal evaluation, frequency of eating out, drinking, smoking, activity, subjective health evaluation, and body weight changes showed significant differences by household type. Attitude towards nutrition, activity, meal evaluation, obesity, and smoking were factors that affected the intake of dietary supplements.Conclusions:
While increased intake of dietary supplements is a prevalent phenomenon, this intake needs to be monitored and studied closely, considering the sociodemographic characteristics and dietary and health-related behaviors. Furthermore, the dietary supplement intake trend after COVID-19 needs to be studied along with food intake.
