OBJECTIVES To evaluate vitamin D status in internationally adopted children at first medical evaluation in Italy and to identify possible risk factors for hypovitaminosis D in this population. METHODS 25-hydroxyvitamin D [25(OH)D] levels were analyzed in internationally adopted children consecutively recruited at one Italian Center between 2010 and 2014 as part of the first screening protocol...

CONTEXT Hypovitaminosis D has been implicated as a possible risk factor for the development of cardiovascular disease. High-sensitivity C-reactive protein (hs-CRP) has been one of the most extensively studied biomarkers for cardiovascular inflammation as an indicator of disease and event risk, independent of traditional risk factors. To date, it is unclear if correction of hypovitaminosis D lea...

BACKGROUND This study aims to assess the relationship of serum Mg and vitamin D levels in a nationally-representative sample of Iranian adolescents. METHODS The study participants consisted of 330 students, aged range from 10 to 18 years, consisting of an equal number of individuals with and without hypovitaminosis D. The correlation between serum 25 hydroxy vitamin D (25(OH) D) and magnesium...

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 ( micro g/d), and bone mineral density (g/cm(2)) were measured in a cross-sectional study of 112 s...

BACKGROUND Back pain is a major public health problem due to its high frequency, to the resulting activity constraint, and the need for surgery in many cases. Back pain is more frequent in women than men, mainly in postmenopausal women. High prevalence of hypovitaminosis D has been detected in postmenopausal women, and it is associated with decreased bone mass, sarcopenia, vertebral fractures, ...

BACKGROUND Pregnant women form one of the high risk groups facing hypovitaminosis D. Low level of vitamin D will affect directly or indirectly both mother and fetus. Screening vitamin D in the first trimester of pregnancy is important to determine the necessary preventive action. Therefore, this study was aimed to determine the prevalence of hypovitaminosis D and its risk factors among pregnant...
