Nutrition assessment of vitamin A and vitamin D in northeast Chinese population based-on SPE/UPLC/PDA

Vitamin D deficiency and hyperparathyroidism in relation to ethnicity: a cross-sectional survey in healthy adults

A global representation of vitamin D status in healthy populations
TLDR
This study provides an overview of 25(OH)D levels around the globe and reveals large gaps in information in children and adolescents and smaller but important gaps in adults, as well as examining the existing heterogeneities in vitamin D status and identifying research gaps.
Vitamin D Status of Inuit Preschoolers Reflects Season and Vitamin D Intake 1 , 2
TLDR
Analysis of Inuit preschoolers living in 16 Arctic communities and participating in the 2007–2008 Nunavut Child Inuit Health Survey found that children who met or exceeded the adequate intake, those who consumed 2 or more milk servings, and those who lived in households without crowding had a better vitamin D status than those who did not.
A systematic review of vitamin D status in populations worldwide
TLDR
Examination of patterns of 25-hydroxyvitamin D levels worldwide and differences by age, sex and region suggested that newborns and institutionalised elderly from several regions worldwide appeared to be at a generally higher risk of exhibiting lower 25(OH)D values.
Vitamin D insufficiency in a sunny environment: a demographic and seasonal analysis.
TLDR
The results suggest that hypovitaminosis D is common across all ages, genders and seasons in Israel, a country characterized by a sunny Mediterranean climate.
The prevalence of hypovitaminosis D among US adults: data from the NHANES III.
TLDR
Serum levels of 25(OH) D3 are below the recommended levels for a large portion of the general adult population and in most minorities, and need exists for a critical review and probable revision of current recommendations for adult vitamin D intake to maintain adequate levels.
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.
Vitamin D status of older South Africans.
TLDR
The prevalence of suboptimal vitamin D status was high in older coloured' South Africans who had not sustained a fracture, and the interpretation of the data, with regard to bone health, is limited by the cross-sectional design of the study.
Vitamin D status in healthy postmenopausal Iranian women

Findings indicate that 25(OH) D levels in postmenopausal women of north-west Iran are low, and studies to elucidate and assess the dietary intake of vitamin D in elderly women of this region can be of further benefit.
