| Popis: | ObjectiveWe hypothesized that young adults would commonly have vitamin D deficiency and that a questionnaire could help identify subjects with the condition.DesignBetween January and May 2004, we administered a questionnaire to a convenience sample of young adults. We measured each participant’s serum level of 25-hydroxyvitamin D (25(OH)D) using a chemiluminescent assay and defined deficiency as serum 25(OH)D < 16 ng/ml.Setting and subjectsWe recruited young adults living in Madison, Wisconsin without pre-existing conditions affecting vitamin D and/or Ca metabolism.ResultsOne hundred and eighty-four adults (mean age 24 years, 53 % women, 90 % Caucasian) participated in the study. Nearly three in four adults (71 %) had 25(OH)D level P = 0·004), tanning booth use (OR = 0·09, 95 % CI 0·02, 0·43, P = 0·002) and daily ingestion of two or more servings of milk (OR = 0·21, 95 % CI 0·09, 0·48, P < 0·001) were less likely to be deficient. These three questions provided a sensitivity and specificity of 79 % and 78 %, respectively, for the presence of deficiency.ConclusionsThe questionnaire is moderately useful to identify young adults likely to be vitamin D-deficient. Additional revisions of the questionnaire may improve its ability to predict vitamin D deficiency. |
