Association between lipid profiles and osteoporosis in postmenopausal women: a meta-analysis

OBJECTIVE: To investigate the relationship between blood lipid profiles and osteoporosis in postmenopausal women.

MATERIALS AND METHODS: A comprehensive search of the literature related to lipid profiles and postmenopausal osteoporosis was conducted in Wanfang Database, CNKI, PubMed (1950-2015) and EMBASE (1974-2015). Appropriate studies were selected according to pre-defined exclusion criteria, and the levels of high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), triglycerides (TG) and total cholesterol (TC) were compared between osteoporosis and normal density groups. Statistical analysis was performed using RevMan5.3.

RESULTS: Ten published articles were selected for meta-analysis. The results showed that the levels of HDL, LDL, TC were higher in the osteoporosis group than the normal density group, whereas the levels of TG were lower in the osteoporosis group (HDL: MD = 2.63, 95% CI: 0.43 to 4.84, p = 0.02; LDL: MD = 9.67, 95% CI: -0.10 to 19.44, p = 0.0532; TG: MD = -0.42, 95% CI: -17.52 to 16.67, p = 0.96; TC: MD = 14.82, 95% CI: 2.84 to 26.80, p = 0.02). There was no statistical difference in LDL and TG.

CONCLUSIONS: The serum levels of HDL and TC are higher in postmenopausal osteoporosis patients, and may thus be potentially useful indicators to reflect the process of osteoporosis in these women. More research is needed to determine the relationship between LDL, TG and postmenopausal osteoporosis.
