Serum carotenoid concentrations in postmenopausal women with and without osteoporosis1
Carotenoid (µmol/L) |
Osteoporosis n = 27 |
Control n = 26 |
---|---|---|
Lutein | 0.62 ± 0.31 | 0.49 ± 0.41 |
Zeaxanthin | 0.10 ± 0.11 | 0.06 ± 0.04 |
β-Cryptoxanthin | 0.27 ± 0.18 | 0.43 ± 0.362 |
Lycopene | 1.22 ± 1.21 | 1.97 ± 1.013 |
α-Carotene | 0.36 ± 0.34 | 0.27 ± 0.22 |
β-Carotene | 1.55 ± 1.15 | 1.10 ± 1.11 |
Values presented are means ± SD. Using multiple linear regression, the model was adjusted for age because of the large age range in the sample and BMI because of significant differences between groups.
Using Student’s t-test, β-cryptoxanthin concentration is higher in the control group (p = 0.04); however, after adjusted for BMI and age, group difference is no longer significant in the regression analysis.
Lycopene concentrations are significantly higher in the control group as compared with the osteoporosis group (p = 0.03) after adjusting for age and BMI.
