High Low-Density Lipoprotein Cholesterol Levels and Early-Onset Vasomotor Symptoms

Higher serum levels of low-density lipoprotein cholesterol are positively related to the risk of early-onset vasomotor symptoms in premenopausal women.

The predominant symptoms evident during the menopausal transition are vasomotor symptoms, including night sweats and hot flashes. Long-lasting and severe vasomotor symptoms tend to be associated with obesity, adverse cholesterol levels, high blood pressure, and other cardiovascular disease risk factors.

This study investigated the association between a greater risk of early-onset vasomotor symptoms and adverse lipid profiles in premenopausal women. The findings were published in the journal Scientific Reports.

Characteristics of the Study Population

Out of 2450 vasomotor symptom-free premenopausal women at baseline, 1243 women experienced early-onset vasomotor symptoms during the follow-up period. The mean age and body mass index (BMI) of the study participants were 44.6 ± 2.3 years and 22.3 ± 3.0 kg/m2, respectively.

Early-Onset Vasomotor Symptoms and Lipid Profiles

The incidence rate of early-onset vasomotor symptoms in premenopausal women at baseline was 11.1 per 100 person-years. There was a significant association between higher LDL cholesterol levels and increased early-onset vasomotor symptom risk. However, triglycerides, total cholesterol, and high-density lipoprotein (HDL) cholesterol were not significantly related to incident vasomotor symptoms.

Moderate or Severe Vasomotor Symptoms and Lipid Profiles

The sensitivity analysis results indicated a significant association between an increased moderate/severe vasomotor symptom risk and LDL cholesterol levels in premenopausal women. On the contrary, the association between other moderate/severe vasomotor symptoms and other lipids was insignificant.
