Vitamin D deficiency is common in adolescents worldwide, and the list of reported detrimental health effects associated with this deficiency continues to grow [1]. Even subclinical deficiency during adolescence may affect bone acquisition, potentially reducing peak bone mass and increasing the risk of osteoporosis in later life. Current evidence suggests that giving vitamin D supplements to ado...

BACKGROUND Osteoporosis is a serious global health problem for the future, that is why improving diagnostic methods and prevention of this disease could be helpful. OBJECTIVES To assess the effects of calcium supplementations combined with Vitamin D on bone mineral density (BMD) and bone mineral content (BMC) in a representative sample of peri- and post-menopausal women in a double-blind, a r...

Background: Ageing of population worldwide will be responsible for a major increase of the incidence of osteoporosis in elderly. For the individual, osteoporotic fractures result in great disability as well as loss of quality of life and also represent an enormous burden for healthcare systems. This study was conducted to determine the prevalence of osteoporosis and it's association with serum ...

This study purposed to investigate the relationship between physical activity level and bone mineral density (BMD) in the elderly of Amirkola in northern Iran. This cross-sectional study was part of a proposal to assess the situation of the elderly in Amirkola (AHAP) (Amirkola Health and Ageing Project) conducted on 1113 elderly individuals (616 males and 497 females) in Amirkola city. Physic...

OBJECTIVE To determine the prevalence, reasons, source of information of vitamin-mineral supplement uses, and their relationship with selected demographic and lifestyle characteristics among Jordan University students. METHODS A cross-sectional survey was carried out at Jordan University, Amman, Jordan from March to September 2005. The survey included 1,187 students aged 17-28 years. A multis...

OBJECTIVE Parathyroid hormone (PTH) and vitamin D are the most important hormones regulating calcium metabolism. In primary hyperparathyroidism (PHPT) excessive amounts of PTH are produced. Bone turnover is enhanced, leading to reduced bone mineral density and elevated levels of serum calcium. The aim of this study was to investigate relations between serum levels of 25-hydroxyvitamin D (25(OH)...

Cardiovascular disease (CVD) and vitamin D deficiency are extremely prevalent worldwide (Holick 2007; World Health Organization 2011). The potential link between vitamin D deficiency and CVD-related death in both healthy and diseased populations is a growing area of translational research. Historically, the traditional role of vitamin D in maintaining calcium homeostasis and mineral metabolism ...

  Background: The main purpose of this study was to determine the relationship between serum vitamin D and the status of bone mineral density in patients with low-energy hip and distal radius fracture. Methods: This retrospective case-control study was performed between January 2013 and January 2014. Participants aged 55 years or older were divided to case group including 85 patients with lo...
