Objective: Limited nationally-representative data are available on the use of and nutrient exposures from dietary supplements (DS) in infants and toddlers; such information is needed to inform policy and research needs.
Objective: To characterize DS use, estimate nutrient intake from DS, and assess DS trends over time among U.S. infants and toddlers.
Methods: Using NHANES data (2007-2014), we estimated the prevalence of taking at least 1 DS in the past 30 days by demographic characteristics and feeding practices for U.S. infants and toddlers aged <2 years (n=2,823). We estimated average daily intake for vitamins and minerals typically consumed through DS by age groups and by feeding practice for infants 0-5.9 months (mo). We also assessed DS trends over time using NHANES 1999-2014. SUDAAN was used to analyze data, incorporating the survey design and weights; group differences were compared using a t statistic, and tests of trend across ordinal variables were examined using orthogonal contrast matrices.
Results: Overall, 18.2% of infants and toddlers used at least 1 DS in the past 30 days (19.2% boys; 17.1% girls). Usage was higher in toddlers (12-23.9 mo; 23.3%) compared with infants (0-5.9 mo; 14.6% and 6-11.9 mo; 11.6%). Vitamin D and multivitamin infant drops were the most commonly reported supplement products for those <12 mo; whereas chewable multivitamin products were most common among toddlers (12-23.9 mo). For those consuming vitamin D or a supplement containing vitamin D, the average daily intake from DS was 7.4 mcg/day, for both infants (0-11 months) and toddlers (12-23 months). For those consuming a supplement containing vitamin C, (common in multivitamin products), the average daily intake from DS was 28.3 mg/day for those 0-11 months and 37.2 mg/day for those 12-23 months. DS use has remained steady for infants 6-11.9 mo and toddlers 12-23.9 mo from 1999-2002 to 2011-2014. For the same time period, DS use has increased for infants 0-5.9 mo from 7% to 20%; largely due to the increased use of vitamin D supplements.
Conclusions: Our findings show that 1 in 5 children under 2 years of age use at least 1 DS. DS contribute key nutrients such as vitamin D to the diets of U.S. infants and toddlers.
