Vitamin D deficiency is common in non-Western immigrant groups living in Western countries. A comparison of vitamin D status in individuals who have emigrated and individuals who remain in their country of origin is needed in order to provide information about the effect of moving to northern latitudes. A total of 196 participants aged 30–60 years in a cross-sectional population-based study in Kandy, Sri Lanka (latitude 7° north) and 242 Sri Lankans aged 31–60 years participating in a cross…

Variation of circulating 25-Hydroxyvitamin D levels with life style in a cohort group in Sri Lanka
TLDR
It is demonstrated that there was no statistically significant correlation between the serum vitamin D with age, serum calcium or total proteins, and the majority of participants who had exposure to the sunlight more than 30 mins/day had sufficient level of vitamin D and less than 30 min/day exposure had deficiency ofitamin D.
Low serum vitamin D among community-dwelling healthy women in Sri Lanka
TLDR
Vitamin D insufficiency/deficiency is prevalent among healthy young and middle-aged women in this study group selected from southern Sri Lanka and the accompanying rise of PTH indicates the biological significance of low vitamin D level.
Maternal Vitamin D Status and Its Effect on Vitamin D Levels in Early Infancy in a Tertiary Care Centre in Sri Lanka
TLDR
Investigation in a state sector tertiary care centre in Sri Lanka found the presence of Vitamin D deficiency/insufficiency is higher in infants compared to pregnant/lactating mothers and low maternal 25(OH)D during pregnancy was a risk factor for deficiency in infants.
Seasonal variance of 25-(OH) vitamin D in the general population of Estonia, a Northern European country
TLDR
Vitamin D insufficiency is highly prevalent throughout the year in a population without vitamin D dairy fortification living at the latitude of 59°N, a North-European country where dairy products are not fortified with vitamin D.
Vitamin D deficiency in western dwelling South Asian populations: an unrecognised epidemic
  • A. Darling

    Proceedings of the Nutrition Society
  • 2020
TLDR
It is concluded that vitamin D deficiency is epidemic in South Asians living in western countries and there is a clear need for urgent public health action.
Vitamin D status in recently arrived immigrants from Africa and Asia: a cross-sectional study from Norway of children, adolescents and adults
TLDR
The majority of recently settled immigrant groups from the Middle East, South Asia and Africa had 25(OH)D <50 nmol/L, in contrast to East Asians, and female adolescents from these regions had the lowest levels of 25( OH)D.
SUNLIGHT EXPOSURE AND SERUM VITAMIN D STATUS AMONG COMMUNITY DWELLING HEALTHY WOMEN IN SRI LANKA
TLDR
Assessment of the prevalence of vitamin D deficiency and its associations with diet and sunlight in premenopausal women in Sri Lanka found higher vit-D level is associated with sufficient duration of sun exposure and dairy, non-dairy food intake.
Differences in the dietary requirement for vitamin D among Caucasian and East African women at Northern latitude
TLDR
Evidence is added that ethnic differences in the dietary requirement for vitamin D do exist and that dose–response vitamin D intervention studies are required in at-risk target populations specified by ethnicity.
Vitamin D status of refugees arriving in Canada
TLDR
Most refugees had lower-than-desirable vitamin D levels compared with the general Canadian population and female refugees between the ages of 12 and 19 years old had lower mean values than male refugees in the same age group did.
Vitamin D deficiency was common in all patients at a Swedish primary care centre, but more so in patients born outside of Europe
TLDR
Lower levels of vitamin D and the prevalence ofitamin D deficiency were more common in patients born outside Europe compared to patients born in Europe.

Prevalence and predictors of vitamin D deficiency in five immigrant groups living in Oslo, Norway: the Oslo Immigrant Health Study
TLDR
There is widespread vitamin D deficiency in both men and women born in Turkey, Sri Lanka, Iran, Pakistan and Vietnam residing in Oslo, and it is higher in men born in Pakistan and lower in those born in Vietnam compared to the other ethnic groups.

Prevalence and significance of low 25-hydroxyvitamin D concentrations in healthy subjects in Delhi.
TLDR
Healthy subjects with low 25(OH)D concentrations are at risk of bone mineral metabolic imbalance when exposed to factors that strain bone mineral homeostasis.
Vitamin D metabolism is altered in Asian Indians in the southern United States: a clinical research center study.
TLDR
In Asian Indians serum vitamin D and 25(OH)D are markedly reduced, altered vitamin D metabolism is only partially reversed by 25( OH)D3, and 25-24-hydroxylase activity in cultured skin fibroblasts is markedly increased, Thus, Asian Indians residing in the U.S. are at risk for developing vitamin D deficiency, rickets, and osteomalacia.

TLDR
The findings show that vitamin D deficiency is common in urban north Indian hospital staff, and the possible reasons include inadequate sunlight exposure and skin pigmentation in Indians.
Comparative study of bone mineral density, calcium, and vitamin D status in the Gujarati and white populations of Leicester
TLDR
The present study is the first of its kind to note a low BMD in Gujarati subjects of South Asian origin compared with their white counterparts, living in Leicester and confirms the presence of low serum vitamin D levels in Gujaratis.
