Blood pressure around the menopause: a population study

Area of Science:

• Cardiovascular Health
• Menopause Research
• Public Health

Background:

• Hypertension is a significant cardiovascular risk factor, particularly in postmenopausal women.
• Existing research on menopause's impact on blood pressure yields inconsistent findings.
• This study investigates menopause's effect on blood pressure within a representative population.

Purpose of the Study:

• To determine the influence of menopause on blood pressure levels.
• To clarify the relationship between menopausal status and hypertension prevalence.
• To differentiate the effects of hormonal changes versus other factors on blood pressure.

Main Methods:

• A population-based sample of 908 women aged 45-54 years was randomly selected.
• Menopause was defined using self-reported menstrual history, follicle-stimulating hormone levels, or both.
• Blood pressure, BMI, and other cardiovascular risk factors were assessed.

Main Results:

• No significant differences in systolic or diastolic blood pressure were observed across menopausal groups.
• The prevalence of hypertension and its odds ratio did not vary by menopausal status.
• Body mass index (BMI) showed the strongest correlation with blood pressure, surpassing age and other factors.

Conclusions:

• The increase in blood pressure around menopause is primarily attributed to rising BMI.
• Ovarian failure itself does not appear to be a direct cause of elevated blood pressure.
• Weight management may be crucial for controlling blood pressure in women during menopausal transition.
