BackgroundBlood lipid profiles have been suggested to be a risk factor for osteoporosis. However, the association between lipid profiles and bone mineral density (BMD) is still unclear. This study aimed to evaluate an association between blood lipid profiles and BMD through both a cross-sectional and a longitudinal study.MethodsStudy subjects were 958 postmenopausal Korean women who have repeatedly undertaken laboratory tests and BMD measurements at lumbar spine and femur neck with an interval of 7.1 years. The associations between lipid profiles and BMD were examined using Spearman correlation analysis with an adjustment for age, smoking, alcohol drinking, physical activity, body mass index, and follow-up duration.ResultsLumbar spine BMD was not associated with total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HLD-C) regardless of when the measurement was performed. In an analysis using data measured at the beginning of the study, femur neck BMD was not associated with TC and LDL-C. However, femur neck BMD showed weak but significantly positive correlation with HDL-C (correlation coefficient, 0.077; 95% confidence interval, 0.005 to 0.149). When the analysis was repeated with data measured at the end of the follow-up, there was no significant correlation between femur neck BMD and any lipid profile. In addition, change in femur neck BMD during follow-up was not associated with the change in lipid profiles.ConclusionAlthough further study with a consideration of calcium intake and osteoporosis medication seems necessary, this study found no association between serum lipid profiles and BMD in postmenopausal Korean women.

“…Calcium intake was lower in the hypercholesterolemia group, but not in the high-Lp(a) group, probably due to the decrease in dairy foods secondary to low-fat diet [7,21,22] and it is suggested that the restriction in calcium intake due to low-fat diet may be responsible for low bone mass [21]. In a casecontrol study comparing 311 postmenopausal women with hypercholesterolemia following a low-fat diet with low dairy calcium intake (<214 mg/day) with 622 healthy postmenopausal women with high dairy calcium intake (>857 mg/day), the prevalence of lumbar osteoporosis was higher in the, hypercholesterolemia group (42.1% vs. 22.3%) suggesting the authors that the restriction in calcium intake due to the low-fat diet may have been responsible for low bone mass [21].…”

“…In the early nineties it was reported that osteoporotic Czech women with and without vertebral fractures had higher serum cholesterol concentration than age-matched normal controls, suggesting a possible association between atherosclerosis and osteoporosis [6]. A more recent study found that the LDLc/HDLc ratio was negatively associated with BMD in postmenopausal women without risk factors for cardiovascular disease and osteoporosis [7]. In a recent longitudinal study in postmenopausal women aged 50-75 years, those with the largest increases in serum cholesterol showed the greatest decreases in spine BMD independently of the change in the body mass index [8].…”

Epidemiological studies have reported that women with osteoporosis present an increased risk of cardiovascular events and that lipid lowering therapy (statins) could be associated with a decreased risk of fracture. We investigated whether women with atherogenic lipid profile have lower lumbar and femoral bone mineral density (BMD) and higher prevalence of osteopenia than those with normal lipid levels. The study included 52 overweight early postmenopausal women, with no history of hormone replacement therapy, or any current or past pathology or treatment that could alter bone or lipid metabolism. Atherogenic lipid profile or hyperlipidemia was defined as hypercholesterolemia (> or = 240 mg/dl) or high low-density lipoprotein cholesterol (high-LDLc > or = 160 mg/dl) or high lipoprotein (a) [high-Lp (a) > or =25 mg/dl], and low-BMD as t-score <-1 SD at lumbar o femoral site. The results show that women with hyperlipidemia had lower mean-adjusted BMD (mean+/-SEM) at lumbar (0.865+/-0.020 vs. 0.958+/-0.028 g/cm2, p = 0.007) and femoral neck (0.712+/-0.015 vs. 0.796+/-0.021, p = 0.004 g/cm2) than those with normal lipid levels. Hypercholesterolemia group had higher prevalence of low-BMD at lumbar spine (82.6% vs. 55.2%, p = 0.04, OR: 3.8; 95% CI: 1.04-14.2) and femoral neck (65.2% vs. 37.9%, p = 0.05, OR: 3.1; 95% CI: 0.98-9.6). The high-LDLc group had also higher prevalence low-BMD at femoral neck (75% vs. 39%, p = 0.01, OR: 4.7; 95% CI: 1.26-17.5), and the high-Lp (a) group at lumbar spine (87% vs. 51.7% p = 0.007, OR: 6.2; 95% CI: 1.5-25.6). Women with hyperlipidemia had higher prevalence of low BMD at lumbar spine (81.8% vs. 42.1%, p = 0.003, OR: 6.2; 95% CI: 1.7-22) and femoral neck (60.6% vs. 31.6%, p = 0.04, OR: 3.3; 95% CI: 1.01-11.0). In conclusion, early postmenopausal women with atherogenic lipid profile, defined as cholesterol > or =240 mg/dl or LDLc > or = 160 mg/dl or Lp(a) > or = 25 mg/dl have lower lumbar and femoral BMD and have an increased risk of osteopenia than those with normal lipid profile, suggesting that hyperlipidemia could be associated with osteoporosis and bone status should be evaluated in women with hyperlipidemia.

A number of recent findings seem to indicate that fat and bone metabolism are strictly connected. We investigated the relationship between lipid profile and bone mineral density (BMD) in 236 either pre- or postmenopausal women, aged 35-81 years, attending our osteoporosis center ("clinic group"). In order to verify the consistency of the results, 265 men and 481 women aged 68-75, participating in a population-based epidemiological investigation ("community cohort"), were also studied. Lumbar spine, femoral neck, total hip and total body BMD, total body fat, % fat mass and lean mass were measured using dual energy X-ray absorptiometry (DXA). In the clinic group, lumbar spine and hip BMD Z score values were both strongly related to all measured serum lipids: the relationship was negative for HDL cholesterol ( P < 0.05) and Apo A lipoprotein ( P < 0.000) and positive for LDL cholesterol ( P < 0.05), Apo B lipoprotein ( P < 0.001) and triglycerides ( P < 0.05). When BMD values were adjusted for body weight and BMI, most relationships remained statistically significant. In the community cohort, total body and hip BMD values were strongly related in both men and women to age, body weight, height, BMI, fat mass, lean mass, % fat mass. Total body and hip BMD were significantly related to serum lipids in both women and men. The relationship was negative for HDL cholesterol and positive for total cholesterol, triglycerides and LDL cholesterol. Most of these relationships (triglycerides, HDL cholesterol, LDL/HDL cholesterol ratio in women, and all measured lipids in men) remained statistically significant ( P values ranging from 0.000 to 0.03) when the BMD values were adjusted also for anthropometric measures (body weight, height, fat mass). This study demonstrates for the first time that the lipid profile is strictly related to bone mass in both men and women. The interpretation of this association remains hypothetical but it might open new perspectives for understanding the mechanisms controlling bone metabolism.
