Anemia and vitamin D deficiency are conditions that both result in significant morbidity and increase with age. The potential relationship between them remains poorly understood, particularly in the elderly. We used the Third National Health and Nutrition Examination Survey to examine the association of vitamin D deficiency with anemia subtypes in persons aged ≥ 60 years. Vitamin D deficiency w...

Background and Objectives: The polycystic ovary syndrome (PCOS) is one of the most common diseases diagnosed in women of childbearing age which is associated with increased risk of metabolic complications, including cardiovascular disease. Increasing C-reactive protein (CRP) as an inflammatory factor is common in these patients. In addition, vitamin D deficiency is quite common among females wi...

UNLABELLED Chronic liver disease (CLD) and several related extrahepatic manifestations such as hepatic osteodystrophy are associated with deficiency of vitamin D, which has therefore been suggested as therapeutic target. Vitamin D undergoes hepatic 25-hydroxylation, rendering the liver critical to the metabolic activation of this vitamin. Vitamin D deficiency is highly prevalent in CLD patients...

BACKGROUND Vitamin D deficiency has been associated with acute stroke and other cardiovascular diseases in the developed world. Low 25-hydroxyvitamin D (25OHD) has been described in some populations in Sub-Saharan Africa (SSA) in spite of adequate sunshine all year round. There is no information on the magnitude of vitamin D deficiency among patients with stroke and other cardiovascular disease...

Vitamin B12 deficiency is common among the elderly. Elderly people are particularly at risk of vitamin B12 deficiency because of the high prevalence of atrophic gastritis-associated food-cobalamin (vitamin B12) malabsorption, and the increasing prevalence of pernicious anaemia with advancing age. The deficiency most often goes unrecognised because the clinical manifestations are highly variable...

  Background : There is no data available regarding vitamin D status among patients with hip fractures in Iran. This study aimed to determine whether postmenopausal women with low trauma hip fractures have lower vitamin D levels comparing to the control group.   Materials and Methods: Vitamin D (25-OHD) level and the prevalence of hypovitaminosis D among 73 postmenopausal women wit...

It is well documented that a large percentage of the general population is either vitamin D insufficient or deficient. Vitamin D deficiency adversely affects bone health. More recently, it has been reported that vitamin D is an important component in immune function and glycemic control Substantial data exist that demonstrate an association between vitamin D insufficiency/deficiency and mortali...

BACKGROUND Vitamin D deficiency is prevailing in Saudi Arabia. Recent national data indicated an inverse association between vitamin D status and coronary heart disease (CHD), which increases concerns about vitamin D deficiency as a serious public health problem. Therefore, the current study aimed to investigate whether knowledge, attitudes and behaviors related to vitamin D contribute to the p...

background and objective: there has been a resurgence of nutritional rickets in children in many developing countries. furthermore, vitamin d deficiency is one of the major health problems and unexpectedly has a high prevalence in sunny countries (e.g. middle east). in order to find out the association between vitamin d deficiencies in mothers and their neonates, we designed this study. methods...

OBJECTIVES The aim of this study was to assess 25-hydroxyvitamin D (vitamin D) status in an HIV-infected adult population and to define HIV- and antiretroviral-related factors associated with vitamin D deficiency. METHODS Using data from a prospective cohort of HIV-infected adult patients followed in five French centres (Dat'AIDS cohort), we evaluated the prevalence of vitamin D deficiency/in...
