Association of Glycosylated Hemoglobin Levels With Vitamin D Status

Association of Glycosylated Hemoglobin Levels With Vitamin D Status

Background The discovery of vitamin D is one of medicine's great achievements. Despite all the positive evidence emerging about the beneficial effect of vitamin D, we still find many are vitamin D deficient. The purposes of this study were to examine the association between serum 25-hydroxyvitamin D (25(OH)D) and glycosylated hemoglobin (HbA1c) levels, to test the hypothesis that lower 25(OH)D ...

Association of vitamin D level with alopecia areata

Background: Alopecia areata (AA) is an autoimmune disorder ofhair follicles. We aimed to find the association between VitaminD level and AA.Method: Eligible AA patients and controls were enrolled inthis case-control study and serum samples were assessed for25-hydroxy vitamin D (25-(OH)-D3). The ...

Vitamin D Status and Its Association with Attention Deficit Hyperactivity Disorder (ADHD) in Children

Association of vitamin D status with serum androgen levels in men.

OBJECTIVE Studies in rodents indicate a role of vitamin D in male reproduction, but the relationship between vitamin D and androgen levels in men is largely unexplored. We aimed to investigate the association of 25-hydroxyvitamin D [25(OH)D] levels with testosterone, free androgen index (FAI) and SHBG. Moreover, we examined whether androgen levels show a similar seasonal variation to 25(OH)D. ...

Association of glycosylated hemoglobin (HbA1c) levels with Iinsulin resistance in obese children.

OBJECTIVES We investigated the relationship between insulin resistance reflected by homeostasis model assessment (HOMA-IR) index and serum HbA1c levels of obese children. MATERIAL AND METHODS This study included 70 obese and 60 normal weight healthy children between the ages of 3 and 15. Anthropometric measures and biochemical tests (fasting glucose, fasting insulin, HbA1c) were performed on ...
