VITAMIN D INTAKE AND STATUS
- In 1988-1994, as part of the third National Health and Nutrition Examination Survey (NHANES III), the frequency of use of some vitamin D-containing foods and supplements was examined in 1,546 non-Hispanic African American women and 1,426 non-Hispanic white women of reproductive age (15-49 years).
- In both groups, 25(OH)D levels were higher in the fall (after a summer of sun exposure) and when milk or fortified cereals were consumed more than three times per week. The prevalence of serum concentrations of 25(OH)D ≤15 ng/mL was 10 times greater for the African American women (42.2%) than for the white women (4.2%).
- The 2000-2004 NHANES provided the most recent data on the vitamin D nutritional status of the U.S..
- Generally, younger people had higher serum 25(OH)D levels than older people;
- males had higher levels than females; and
- non-Hispanic whites had higher levels than Mexican Americans,
- who in turn had higher levels than non-Hispanic blacks.
- Depending on the population group,
- 1-9% had serum 25(OH)D levels <11 ng/mL ,
- 8-36% had levels <20 ng/mL, and
- the majority (50-78%) had levels <30 ng/mL .
- Among adults in the United Kingdom, nationally representative data collected between 1992 and 2001 show that
- 5-20% in most age groups on average had serum 25(OH)D levels <10 ng/ml;
- the prevalence of deficiency was greater (range 20-40%) for older people >65 years of age in residential care homes and among women >85 years.
- Among all adults, 20-60% had levels ≤20 ng/ml and
- 90% had levels ≤32 ng/ml.
