Association of 25-hydroxyvitamin D with sex hormones and body composition in Chinese older adults.

ABSTRACT:

Background

Evidence from several studies suggests that vitamin D deficiency is associated with reduced testosterone levels. However, evidence regarding the relationships between serum 25-hydroxyvitamin D [25-(OH)D] and sex hormones remains inconsistent.

Methods
