Background Neonatal sepsis is a critical condition caused by a generalized bacterial infection in the first month of life. The present study aimed to investigate the relationship between serum vitamin D levels and neonatal sepsis. Materials and Methods: A search of online databases (Medl...

Background. Vitamin D deficiency is widespread throughout the world. Several reports have incriminated vitamin D deficiency as the cause of rickets, osteomalacia, and other chronic diseases. Recent studies have suggested a possible link between deficiency of 25-hydroxyvitamin D and dyslipidemia. Aim. To investigate the association between 25-hydroxyvitamin D deficiency and dyslipidemia in India...

BACKGROUND The role of dairy calcium intake and serum vitamin D concentrations in weight loss is controversial. OBJECTIVE The objective was to assess the association of dairy calcium intake and serum vitamin D with weight loss. DESIGN We analyzed data from participants in the 2-y Dietary Intervention Randomized Controlled Trial (DIRECT) [n = 322; mean body mass index (BMI; in kg/m²): 31; me...

OBJECTIVE To evaluate the prevalence of inadequate vitamin D status and its relationship with associated factors in 91 elderly hypertensive patients in João Pessoa, PB/BR. MATERIALS AND METHODS In a cross-sectional study, levels of 25-hydroxyvitamin D of 91 elderly patients were compared with biochemical, anthropometric, and dietary data, type of skin, exposure to sunlight, and blood pressure...

OBJECTIVES To determine the effect of modifiable dietary intake variables (current vitamin D supplementation and daily cow's milk intake) on 25-hydroxyvitamin D level in early childhood and to evaluate the relationship between these modifiable dietary factors and other largely nonmodifiable determinants of vitamin D status including skin pigmentation and season. DESIGN Cross-sectional study. SE...

The demand for analysis of 25-hydroxyvitamin D has increased dramatically throughout the world over the past decade. As a consequence, a number of new automated assays have been introduced for 25-hydroxyvitamin D measurement. Automated assays have shown variable ability to meet the technical challenges associated with 25-hydroxyvitamin D measurement. Assays are able to meet performance goals fo...

BACKGROUND In cross-sectional studies, low serum levels of 25-hydroxyvitamin D are associated with higher prevalence of cardiovascular risk factors and disease. This study aimed to determine whether endogenous 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D levels are related to all-cause and cardiovascular mortality. METHODS Prospective cohort study of 3258 consecutive male and female patien...

PURPOSE More time outdoors is associated with a lesser risk of myopia, but the underlying mechanism is unclear. We tested the hypothesis that 25-hydroxyvitamin D (vitamin D) mediates the protective effects of time outdoors against myopia. METHODS We analyzed data for children participating in the Avon Longitudinal Study of Parents and Children (ALSPAC) population-based birth cohort: noncyclop...

The increasing breast, colorectal and prostate cancer mortality rates found with increasinglatitude by ecological studies in the USA and in Europe has been equated to lower vitamin D statuswith increasing latitude. We examined in Western, Northern and Southern Europe the associationbetween latitude of residence and serum 25-hydroxyvitamin D levels. We performed a systematicsearc...

OBJECTIVE Serum 25-hydroxyvitamin D is produced by the exposure of the skin to sunlight. Therefore athletes who train indoors, such as dancers, are vulnerable to vitamin D deficiency. The purpose of the study was to evaluate the serum 25-hydroxyvitamin D status in UK professional dancers during periods of reduced and increased sunlight exposure (i.e., winter vs. summer), and to assess the impac...
