25-hydroxy Vitamin D levels of 106 maternal blood samples and cord blood levels of their newborns were studied. Maternal mean (SD) vitamin D level was 16.3 (10.3) ng/mL, and mean (SD) cord blood level was 12.8 (8.5) ng/mL. Seventy-five (70.7% mothers (70.7%) and 88 (83%) newborns had hypovitaminosis- D. Seventy (93.3%) newborns of mothers with hypovitaminosis-D had low vitamin D levels. There w...

OBJECTIVE To investigate vitamin D levels in patients with non-specific musculoskeletal pain, headache, and fatigue. DESIGN A cross-sectional descriptive study. SETTING A health center in Oslo, Norway, with a multi-ethnic population. SUBJECTS A total of 572 patients referred by a general practitioner (GP) for an examination of hypovitaminosis D who reported musculoskeletal pain, headache,...

BACKGROUND A high hypovitaminosis D prevalence has repeatedly been reported in Middle Eastern countries. Previous data regarding the vitamin D status of young women in Saudi Arabia and the related hypovitaminosis D risk factors are scarce, so this research assessed hypovitaminosis D prevalence and its risk factors among apparently healthy female university students in Tabuk, Saudi Arabia. MET...

OBJECTIVES Determine the prevalence and identify predictors of hypovitaminosis D in patients with type 2 diabetes mellitus (T2DM); 2) correlate vitamin D levels with variables indicative of glycemic control and cardiovascular risk. RESEARCH DESIGN AND METHODS We conducted a cross-sectional study with consecutive patients treated at a University Hospital's Endocrinology outpatient clinic locat...

This study investigated the factors associated with hypovitaminosis D, in a cohort of 405 prevalent patients with chronic kidney disease (CKD) stages 2-4, living in Italy and followed-up in tertiary care. The effect of cholecalciferol 10,000 IU once-a-week for 12 months was evaluated in a subgroup of 100 consecutive patients with hypovitaminosis D. Vitamin D deficiency was observed in 269 patie...

Background: Crohn disease (CD) and vitamin D deficiency are associated with decreased bone mineralization. Objective: We examined the prevalence of and risk factors for hypovitaminosis D in children, adolescents, and young adults with CD. Design: Growth, clinical characteristics, vitamin D intake ( g/d), and bone mineral density (g/cm2) were measured in a cross-sectional study of 112 subjects (...

Background: Numerous studies have been conducted to evaluate the frequency of hypovitaminosis D in patients with fibromyalgia syndrome (FMS) and its association with FMS symptoms. This study aimed at assessing the effect of hypovitaminosis D on the symptoms and quality of life of patients with fibromyalgia. Methods: A total of 74 FMS patients with hypovitaminosis D were randomly assigned into ...

There is a high prevalence of hypovitaminosis D in patients with back pain regardless of whether or not they require surgical intervention. Furthermore, the risk of hypovitaminosis D is not limited to individuals with traditional clinical risk factors. Vitamin D plays an essential role in bone formation, maintenance, and remodeling, as well as muscle function. Published data indicate that hypov...

background: sunlight is the main source of vitamin d; therefore, environmental factors might have an important role in the high prevalence of hypovitaminosis d in children. this study aimed to assess the vitamin d status according to the climate of the living area in a nationally representative sample of iranian adolescents. material and methods: this nationwide cross-sectional survey was perfo...

Vitamin D may have an important role in pain perception. Inadequate vitamin D levels are associated with suboptimal recovery after surgery. However, the effects of hypovitaminosis D on postoperative pain-related outcomes and its impact on health-related quality of life after surgery are not well understood. The objective of this study was to determine the effects of hypovitaminosis D on postope...
