Serum 25-hydroxyvitamin D concentration of Indigenous-Fijian and Fijian-Indian women.
BACKGROUND
Serum 25-hydroxyvitamin D (25OHD) concentrations are lower in Pacific people compared to Caucasians living in New Zealand. However, there are no data on the 25OHD concentrations of Pacific people living in the Pacific Islands.


OBJECTIVE
To assess the vitamin D status of indigenous and Indian Fijian women living in Fiji by measuring 25OHD concentrations.


METHODS
25OHD concentrations in a national sample of 511 Fijian women (15-44 y).


RESULTS
The mean 25OHD concentration of Fijian women was 76 nmol/L (95% CI: 73, 78). 25OHD was lower in Fijian Indian [70 (66, 74) nmol/L; n=205] women compared to indigenous Fijians [80 (76, 84) nmol/L; n=306] (p<0.0001). The mean 25OHD was higher in rural [77 (74, 80) nmol/L; n=392] than urban [70 (65, 76) nmol/L; n=119] women (p<0.0001). Body mass index (BMI) and age were not predictors of 25OHD concentrations. Of Fijian females, 3%, 11%, and 56% had 25OHD concentrations indicative of 25OHD insufficiency using cut-offs of < or =37.5, < or =50 and < or =80 nmol/L, respectively.


CONCLUSIONS
Mean 25OHD in Fijian women was generally adequate and exceed concentrations reported in Pacific females living in New Zealand.
