2004 SEP 2 - (NewsRx.com & NewsRx.net) -- Menopausal variations in cholesterol are influenced by apolipoprotein E genotype, researchers report.
"During menopause, a sharp increase in cholesterol concentration occurs with an unexplained wide variation in change. Possibly, this is attributable to genetic variation," wrote A.E. Hak and colleagues, Erasmus MC.
They explored this by "prospectively [studying] the effect of the apolipoprotein E (APOE) genotype on the change in cholesterol level with menopause among 116 Dutch women."
"Women with the APOE3E3 genotype were regarded as the reference category and changes were adjusted for age at baseline, years of follow-up, years since menopause, and body mass index. At baseline, the women were on average 50.4 years," the researchers said.
They reported, "After 5.9 years of follow-up, the women were on average 4.3 years (SD 1.5 years) postmenopausal. The mean increase in cholesterol with menopause in women with the APOE3E3 genotype was 0.67 mmol/L (95% CI, 0.61-0.72 mmol/L). In women with the APOE2E3 genotype the increase in cholesterol was 0.44 mmol/L (Cl, 0.32-0.56 mmol/L). The increase in cholesterol in women with the APOE3E4 genotype did not differ from ...
