vitamin d is essential for growth and vitamin d deficiency is important issue in adolescent girls as they have a limited rapid growth period .this cross sectional study was done on 167 female students in secondary guidance school in 2006. growth parameters, taking supplementary vitamin d, using sunscreen creams and the type of housing and their avoidance from exposure to sunlight was recorded. ...

conclusions the vitamin d levels of children aged more than 2 years are lower than those of children aged less than 2 years. thus, prescribing vitamin d-containing supplements in children older than 2 years may be beneficial. results the final study consisted of 286 children, 140 males and 146 females, with a mean age of 4.46 ± 2.82 yr. of these, 218 (76.22%) children, with a mean age of 5.09 ±...

persistence of benthiocarb in soil as affected by uv and sunlight exposure was studied. treated soil was placed in petri plate, brought to field capacity moisture and then exposed to uv and sunlight. residues of benthiocarb in soil dissipated with half lives of 2.10, 11.85 and 43.63 days under uv, sunlight and dark condition, respectively. soil samples kept under dark showed the slowest dissipa...

Background: Some studies on Multiple Sclerosis (MS) have suggested that adequate vitamin D intake can modulate the course of MS and decreases its incidence. However, there are limited studies with conflicting findings on the relation between MS severity, its course, and vitamin D intake.  Objectives: The current study aimed to compare vitamin D intake and sunlight exposure between MS phenotype...

Background and Objectives: Evidence indicate relationships between the sunlight exposure, vitamin D status and non-melanoma skin cancer (NMSC) risk. Vitamin D receptor (VDR) polymorphisms have been linked to metabolic changes in insulin resistance and various cancers. The purpose of this study is to investigate relationships between the sunlight exposure and the NMSC risk. Furthermore, relation...

BACKGROUND Vitamin D is an important factor in human health. Yet, vitamin D deficiency is very common. We aimed to confirm serum 25-hydroxyvitamin D (25OHD) concentration change after sunlight exposure and to elucidate the relationship between the amount of sunlight exposure and serum 25OHD level change by ambulatory lux meter and sunlight exposure questionnaire. METHODS Twenty healthy young ...

This paper discusses the improvement of the statistical model that was developed in [6] by adding a new weather variable called sunshine. We also took into account other weather factors such as ambient temperature, humidity, wind speed, and sky cover as well as time factors such as the day of the week and the hour of the day. We developed a statistical model that describes the electric power de...

BACKGROUND Sunlight exposure is responsible for a large number of dermatological diseases. OBJECTIVE We estimated the prevalence of sunlight exposure and its associated factors in adults from southern Brazil in a cross-sectional, population-based study. METHODS We investigated a representative sample of individuals aged ≥ 20 years (n=3,136). Sunlight exposure and its associated factors were...

BACKGROUND Prostate cancer (PCa) is the leading cause of cancer in men in many developed countries, but no modifiable risk factors have been identified. A handful of analytical studies have suggested a possible etiological role for sunlight exposure. We report here on the association between leisure-time sunlight exposure during adulthood and PCa risk in the context of a population-based case-c...
