What kind of socio-economic factors play into how much vitamin D you might be getting? Recently, researchers from Texas Woman’s University wanted to find out.
They looked at 11,857 adults 19 years old or older from the NHANES 2007 – 2010 database. They excluded anyone who took high-dose vitamin D, so 9,719 participants met their study inclusion criteria.
Researchers found total (dietary and supplemental) intake of vitamin D was significantly higher in high income groups. Income was associated with vitamin D intakes in all ethnic groups, except for non-white Hispanics.
Additionally, total vitamin D intake of non-Hispanic Whites was greater than that of Hispanics and non-Hispanic Blacks.
Nonetheless, 75.4% of the high income group were not meeting the recommended daily allowance, compared to 84.3% of the middle income level and 86.8% of the low income level.
The researchers wanted to point out that total vitamin D intake in this NHANES database was higher than in previous years.
“Encouraging the consumption of foods naturally high in vitamin D and foods fortified in vitamin D, along with supporting the greater use of dietary supplements, would help to improve the vitamin D status in the USA,” the researchers concluded. “Finally, culture-specific interventions are needed to increase vitamin D supplement use and health messages should be specifically targeted to all males, Blacks and Hispanics.”
