Figure.. Weighted Prevalence Estimates of Dietary Supplement Use by Sex and Age Group Among US Children and Adolescents
Graphs are based on data from the National Health and Nutrition Examination Surveys (NHANES), 2003-2004 to 2013-2014. All data are weighted to account for differential probabilities of selection and differential nonresponse. A, Significance of trends across all 6 NHANES 2-year cycles was tested using survey-weighted logistic regression. Use of alternative medicines nearly doubled from 2003-2004 vs 2013-2014 (3.7%; 95% CI, 2.8%-4.7% vs 6.3%; 95% CI, 4.8%-8.3%; P < .001). B, Survey-weighted logistic regression was used to compare prevalence between boys and girls. Among adolescents (13-19 years), girls reported higher use of any dietary supplements in the preceding 30 days (adolescent girls, 33.4%; 95% CI, 27.0%-40.3% vs adolescent boys, 23.9%; 95% CI, 19.0%-29.7%; P = .06), specifically nutritional products (adolescent girls, 30.3%; 95% CI, 24.8%-36.4% vs adolescent boys, 21.5%; 95% CI, 16.8%-27.1%; P = .04). P values for differences in prevalence between boys and girls are based on a Wald test using design-based estimates of variance.
