BONE MINERAL DENSITY AND SERUM CALCIUM AND PARATHYROID HORMONE LEVELS IN ATHLETIC WOMEN

Abstract

Objective: This study aims to investigate the relationship between serum levels of thyroid stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4), and bone mineral density (BMD) in postmenopausal women, with an emphasis on those who are athletically active. The objective is to understand how these hormonal levels correlate with BMD specifically in athletic women. Methods In this study, 100 female participants aged 45 to 72 years with 2 years of natural menopause were selected. Dual energy X-ray absorptiometry (DEXA) was used to scan the regular bone mineral density of the lumbar spine (L1-L4), femoral neck, Ward's triangle and greater trochanter. According to the level of bone mineral density T, the subjects were divided into normal group (T value ≧-1.0), low bone mass group (T value ≦-2.5) and osteoporosis group (T value ≦-2.5). The TSH, T3 and T4 of 3 groups were compared. Result Compared with normal women, low bone mass and osteoporosis population, the conclusions are as follows: compared with normal women, postmenopausal TSH level is positively correlated with bone mineral density, and low TSH level is more likely to develop osteoporosis; while women with higher TSH level show higher bone mineral density (BMD), and there is a certain correlation between the two. Conclusion Postmenopausal women, especially those with low body weight and low TSH level, are more likely to be an early indicator of osteoporosis prevention and treatment.
