Purpose As the vitamin D status of Algerian postmenopausal women was poorly described, this cross-sectional study investigated the prevalence of low vitamin D status in a sample population. Secondarily, predictive factors of this hypovitaminosis D were explored. Methods All the 336 selected women ≥ 45 years from Douera were interviewed to get anthropometric and lifestyle data, reproductive an...

CONTEXT Hypovitaminosis D appears to be on the rise in young children, with implications for skeletal and overall health. OBJECTIVE The objective of the study was to compare the safety and efficacy of vitamin D2 daily, vitamin D2 weekly, and vitamin D3 daily, combined with supplemental calcium, in raising serum 25-hydroxyvitamin D [25(OH)D] and lowering PTH concentrations. DESIGN This was a...

In this study, we investigated the distribution of vitamin D and its association with carotid atherosclerotic plaque (CP) in Chinese type 2 diabetic (T2D) patients. We performed a cross-sectional study in 210 T2D and 94 age- and gender-matched nondiabetic patients during winter months, by determining serum 25-hydroxyvitamin D (25(OH)D) levels in both diabetic and nondiabetic controls. We carrie...

OBJECTIVE To describe 25-hydroxy vitamin D (25-OH-D) levels and examine associations between 25-OH-D levels and insulin resistance (IR), metabolic syndrome (MS), and glucose intolerance in Arab Americans. RESEARCH DESIGN AND METHODS Serum 25-OH-D levels were measured in a representative, cross-sectional sample of 542 Arab Americans with IR (46%), MS (33%), and glucose intolerance (42%). RES...

Purpose: In this retrospective study we tried to outline the relationship between the ionized calcium (iCa) and secondary hyperparathyroidism (SHPTH) in patients with hypovitaminosis D. Methods: The records of 101 outpatients patients with hypovitaminosis D (25(OH)D < 30 ng /ml) who were also assayed for ionized calcium (iCa), total calcium (tCa) and PTH are presented. They were divided into tw...
