association may have been confounded by different anthropometric variables that were ...

The relationship between obesity and serum 1, 25-dihydroxy vitamin D concentrations in healthy adults

SJ Parikh, M Edelman, GI Uwaifo… - The Journal of …, 2004 - press.endocrine.org
Several previous reports of small cohorts have found significantly higher serum 1, 25-
dihydroxy vitamin D (1, 25-vit D) in obese compared with nonobese whites. Based on these
reports and on recent in vitro studies of adipocytes which suggest that administration of 1, ...

Adequacy of vitamin D replacement in severe deficiency is dependent on body mass index

P Lee, JR Greenfield, MJ Seibel, JA Eisman… - The American journal of …, 2009 - Elsevier
BACKGROUND: Obesity is associated with hypovitaminosis D. Whether body mass index
(BMI) determines the replacement dose of vitamin D to achieve sufficiency is unclear.
OBJECTIVE: To determine the relationship between BMI and serum 25-OH vitamin D ...

adults could have important clinical implications. Few studies relating vitamin D deficiency ...

Body fat content and 25-hydroxyvitamin D levels in healthy women

S Arunabh, S Pollack, J Yeh… - The Journal of Clinical …, 2003 - press.endocrine.org
Obesity is associated with alterations in the vitamin D endocrine system. Lower levels of
serum 25-hydroxyvitamin D (25-OHD) in morbidly obese individuals may be secondary to an
alteration in tissue distribution resulting from an increase in adipose mass. Therefore, ...

Vitamin D status and parathyroid hormone in obese children before and after weight loss

T Reinehr, G de Sousa, U Alexy, M Kersting… - European Journal of …, 2007 - EFES
Objective: The roles of vitamin D and parathyroid hormone (PTH) are discussed
controversially in obesity, and studies of these hormones in obese children are limited.
Therefore, we studied the relationships between PTH, 1, 25-dihydroxy-vitamin D (1, 25- ...

Seasonal variation of 1, 25-dihydroxyvitamin D and its association with body mass index and age

J Moan, Z Lagunova, FA Lindberg… - The Journal of steroid …, 2009 - Elsevier
Under most normal conditions the serum level of 1, 25-dihydroxyvitamin D is constant
throughout the year, due to tight biochemical regulation. In contrast to this, the level of 25-
hydroxyvitamin D is variable through the year, being largest in late summer, due to ...

Serum 1, 25-dihydroxy vitamin D is inversely associated with body mass index

S Konradsen, H Ag, F Lindberg, S Hexeberg… - European journal of …, 2008 - Springer
Abstract Background Based on in vitro studies, it has been hypothesized that 1, 25-
dihydroxy vitamin D (1, 25-vit D) may promote weight gain in humans, but previous studies
have demonstrated conflicting results regarding the association between serum 1, 25-vit D ...
