Comparison of 25-hydroxyvitamin D and Calcium Levels between Polycystic Ovarian Syndrome and Normal Women

Background Given the relationship of vitamin D deficiency with insulin resistance syndrome as the component of polycystic ovary syndrome (PCOS), the main aim of this study was to compare serum level of 25- hydroxyvitamin D [25(OH)D] between PCOS patients and normal individuals. MaterialsAndMethods A cross sectional study was conducted to compare 25(OH)D level between117 normal and 125 untreated...

Comparison of 25-hydroxyvitamin D and Calcium Levels between Preeclampsia and Normal Pregnant Women and Birth Outcomes

Introduction The main aim of this study was to compare serum level of 25- hydroxyl vitamin D [25(OH) D] between women with preeclampsia and normal individuals and birth outcomes. Material and Methods This cross sectional study was conducted on 650 normal primigravida women in their first 24–28 weeks of pregnancy. After 3 months of follow-up, serum levels of 25(OH) D and calcium were measured...

Serum 25-hydroxyvitamin D (25-OH-D) in obese adolescents.

BACKGROUND There is increasing evidence that vitamin D deficiency is common and has been associated with several non-bone related outcomes, including insulin resistance, type 2 diabetes and cardiovascular disease. The influences of gender, puberty, and adiposity on serum hydroxyvitamin D (25-OH-D) levels and the relationship between 25-OH-D and insulin resistance in obese children were studied....

25-Hydroxyvitamin D, cholesterol, and ultraviolet irradiation.

Vitamin D deficiency may have implications for cardiovascular health. The purpose of this study was to determine the relationship of 25-hydroxyvitamin D (25[OH]D) to cholesterol and lipoprotein particles and to determine whether increasing 25(OH)D through ultraviolet (UV) irradiation impacted on these parameters in healthy young men and women. This was a randomized trial of 51 adults exposed to...
