Objective  Because vitamin D synthesis is lower in a heavily pigmented skin than in a lighter skin, the relative contribution of determinants to the vitamin D concentration might differ between ethnic groups. The aim of this study was to assess the prevalence of vitamin D deficiency and the relative contribution of vitamin D consumption and exposure to sunlight to the vitamin D concentration in a multiethnic population. 
Vitamin D Status in South Asian Populations – Risks and Opportunities

TLDR
It is concluded that vitamin D deficiency is highly prevalent among South Asian populations and global efforts are needed to overcome hypovitaminosis in the region.
Diet, sun, and lifestyle as determinants of vitamin D status
TLDR
A combination of sunlight exposure, nutrition, food fortification, and supplements is desirable to obtain sufficient vitamin D status in the population of most countries throughout the year.

A Narrative Review of The Role of Foods as Dietary Sources of Vitamin D of Ethnic Minority Populations with Darker Skin: The Underestimated Challenge
TLDR
Future strategies to increase dietary vitamin D intake by food fortification or biofortification needs to be explored, not only for the majority population but more specifically for ethnic minority populations who are generally of lower vitamin D status.
Associations of Serum Vitamin D Concentrations with Dietary Patterns in US Children
TLDR
Serum 25(OH)D concentrations were associated with Prudent dietary pattern but not with HFLV dietary pattern in US children and adolescents, and should be encouraged to consume more vitamin D fortified foods.
Association between serum 25-hidroxyvitamin D concentrations and ultraviolet index in Portuguese older adults: a cross-sectional study
TLDR
In this sample with high vitamin D deficiency frequency, the UVI was a predictor of 25(OH)D levels but the direction of the association varied according to the blood collection period.
Effect of Food and Vitamin D Supplements on the Serum 25(OH)D3 Concentration in Children during Winter Months
TLDR
In the absence of vitamin D synthesis by sunlight, vitamin D obtained from food has a significant influence on the serum 25(OH)D3 concentration in children, which means the authors should pay more attention to food as a natural source ofitamin D.

Hypovitaminosis D in a Sunny Country: Relation to Lifestyle and Bone Markers
TLDR
In the absence of information regarding time spent outdoors, the results show that hypovitaminosis D is common among young Lebanese people and is related mostly to low vitamin D intake, which should emphasize the need for more vitamin D in the population.
Vitamin D deficiency in Tunisia
TLDR
Dietary enrichment or supplementation by vitamin D and a more outdoor lifestyle, especially for older people, should be seriously considered as a way to reduce this deficiency in Tunisia.

TLDR
It has been more than 3 decades since the first assay assessing circulating 25-hydroxyvitamin D in human subjects was performed and led to the definition of "normal" nutritional vitamin D status, i.e., vitamin D sufficiency, and current dietary recommendations for adults are not sufficient to maintain circulating 25(OH)D levels at or above this level, especially in pregnancy and lactation.
Decreased bioavailability of vitamin D in obesity.
TLDR
Obese subjects had significantly lower basal 25-hydroxyvitamin D concentrations and higher parathyroid hormone concentrations than did age-matched control subjects and the incremental increase in vitamin D(3) was 57% lower in obese than in nonobese subjects.

OBJECTIVE In small case-control studies, obesity was associated with worse vitamin D status. Our aim was to assess the association of adiposity (anthropometric measures as well as dual energy x-ray

TLDR
There were significant changes in serum 25-OHD level from the pre- to the post-menopausal women with a positive correlation between vitamin D intake and serum at the 25- OHD level and multiple regression analysis revealed that the effects of aging could largely be accounted for.
Estimates of optimal vitamin D status
TLDR
Based on the available evidence, it is believed that if older men and women maintain serum levels of 25(OH)D that are higher than the consensus median threshold of 75 nmol/l, they will be at lower risk of fracture.

TLDR
Fortification of milk and other foods with vitamin D in the United States and Sweden has led to a better nutritional state with respect to vitamin D than in the Netherlands, therefore the dairy industry should be allowed to add vitamin D to dairy products to prevent fractures.

TLDR
Vitamin D3 is recommended in housebound elderly, and it may be cost-effective in hip fracture prevention in selected risk groups, and vitamin D3 supplementation may decrease the incidence of hip and other peripheral fractures in nursing home residents.

TLDR
Vitamin D deficiency has a high prevalence in Tehran and supplemental dietary intake seems essential in order to avoid complications of vitamin D deficiency.
