Sun exposure, ultraviolet (UV) irradiance and serum 25 hydroxycholecalciferol (25OHD) in pregnant women in rural North India
نویسندگان
چکیده
Methods The measurements of UVB radiation energy were obtained using UV spectrometer at different times of the day between 9 am and 4 pm, in different seasons. The instrument was calibrated to denote 13 microWatt/ cm2 of irradiance per mVolt of deflection. Measurements were taken at our institution (situated in the countryside), at crowded inner city areas and the villages where our subjects resided. The clothing, outdoor activity pattern, and dietary calcium intake were prospectively documented. Serum 25OHD was measured by radioimmunoassay (Diasorin, Stillwater, MN).

Ultraviolet B sunlight exposure is a primary source of vitamin D. There have been reports of low vitamin D status amongst the Malaysian population despite it being a tropical country. This study was conducted to determine the influence of sun exposure on 25(OH)D concentrations in urban and rural women in Malaysia and factors predicting 25(OH)D concentrations. Women aged above 45 years were recr...
متن کاملHigh prevalence of vitamin D deficiency among pregnant women and their newborns in northern India.
BACKGROUND Vitamin D deficiency is prevalent in India, a finding that is unexpected in a tropical country with abundant sunshine. Vitamin D deficiency during pregnancy has important implications for the newborn and infant. There are few data from India about the prevalence of hypovitaminosis D in pregnancy and in the newborn. OBJECTIVE Our aim was to determine the prevalence of osteomalacia a...

Vitamin D is a fat soluble vitamin that has mainly two types D2 (ergocalciferol) and D3 (cholecalcifererol). While vitamin D can be obtained from dietary sources (D2 isoform) the biggest contribution to an individual’s circulating levels of vitamin D, in most countries, is through endogenous production in the skin following exposure to ultraviolet(UV)-B radiation from the sun. Exposure to UV-B ...
