title: Dietary supplements use and related factors of preschoolers in 3 korean cities.
abstract: OBJECTIVE
  To estimate the prevalence of dietary supplement (DS) use, investigate the related factors associated with DS use among preschoolers and support the adequate nutrition.
  
  
  METHODS
  We conducted a questionnaire survey of mothers of children aged between 1 and 6 years who visited pediatric clinics in 3 Korean cities (Jeonju, Suncheon, Jeongeup) between October and November 2012 at Presbyterian Medical Center. The responses from 929 questionnaires were analyzed.
  
  
  RESULTS
  Approximately 45.1% of the preschoolers used DS in the past month. The following factors were associated with greater use of DS: older age (p<0.001), whether or not the preschoolers attended kindergarten (p<0.001), higher mother's concern about the nutritional facts (p<0.001), whether or not the mother use DS (p<0.001), whether or not the mother counsel with a doctor or pharmacist about DS use (p<0.001). Vitamin·mineral supplements (77.5%) were the most commonly used DS among the preschoolers, followed by ginseng (49.3%) and probiotics (25.6%). Additionally, of the DS users, 95.9% gave DS to their healthy children. Of the users and non-users, 97.6% and 62.2%, respectively, indicated that they would like to have their children take DS. The information on DS was obtained from family or friends in 48.2% of the DS users and from doctors in only 6.1%.
  
  
  CONCLUSIONS
  Approximately half of the preschoolers in our study used DS, which might not have been medically indicated for most of them. Therefore, the role of professionals in counseling on desirable diet behaviors and DS use for preschoolers is warranted.
