(P20-063-24) Vitamin D Dietary Intake and Food Groups Type Among Hispanics/Latinos by Use of Vitamin D Supplements: The Hispanic Community Health Study/Study of Latinos

Objectives: We evaluated the association between vitamin D total usual dietary intake and vitamin D food sources and meeting the recommended Estimated Average Requirement (EAR) by consumption of vitamin D supplements.

Methods: The Hispanic Community Health Study/Study of Latinos is a population-based cohort study of 18–74 year olds from 4 cities in 2008–2011 (Bronx, Chicago, Miami, and San Diego), among 6 heritage groups; Central American, Cuban, Dominican, Mexican, Puerto Rican and South American. We included all participants with at least one 24-hour diet recall (N=16,110). Vitamin D supplementation included multivitamin with D, calcium with D, or singular D and Vitamin D food groups were categorized into 7 groups (Fish/Fish Products, Eggs, Dairy-Milk, Plant-based-Milk, Citrus juice, Ready to eat-Cereals, and Organ meats). The National Cancer Institute method was used to estimate total usual intakes from food alone for non-supplement users and from food/supplements among supplement users. Analysis included, t-test, chi-square, ANOVA, weighted frequencies and means.

Results: Supplement users (n = 2,730) were more likely to have health insurance (52.2% vs 50.1% p=0.04), and an income of $40,001-$75,000 (17.7% vs 14.1% p< 0.001) than non-users (n=13,380). Overall, vitamin D supplement users had lower mean intake of vitamin D food groups (e.g. fish/fish products: 0.76 oz vs 1.29 oz per day) than non-users. For total usual vitamin D intake, supplement users had higher mean intakes (19.3 mcg vs 4.9 mcg per day) and were less likely to be below the EAR (1.5% vs 99.2%) than non-users. There were no significant differences in mean usual vitamin D or food group intake across heritage groups.

Conclusions: We observed that regardless of lower vitamin D food group consumption, Hispanic/Latino individuals taking vitamin D supplements had higher total usual intakes and met the recommended EAR. The significance of vitamin d supplementation in addition to variation in specific food sources can be used to inform the development of tailored interventions for Hispanic/Latino groups at greater risk for vitamin D deficiency.
