Women experiencing premature menopause, whether natural or surgical, have lower bone mineral density (BMD) in early post-menopausal years. Surgical menopause may offer bone protection later in life compared to normal menopause.

Area of Science:

  • Bone health and metabolic disorders
  • Endocrinology and women's health

Background:

  • Menopause significantly impacts bone mineral density (BMD).
  • Different types of menopause (normal, surgical premature, natural premature) may have varying effects on bone health.
  • Understanding these differences is crucial for targeted osteoporosis prevention and management.

Purpose of the Study:

  • To investigate the influence of the timing and type of menopause on bone mineral density (BMD) across different age groups.
  • To compare BMD levels in women with normal menopause (NMP), surgical premature menopause (SUMP), and early natural premature menopause (EMP).

Main Methods:

  • A cross-sectional study involving 514 women with no history of hormonal substitution.
  • Categorization into normal menopause (NMP), surgical premature menopause (SUMP), and early natural premature menopause (EMP) groups.

  • Bone mineral density (BMD) measurement at the lumbar spine (L2-L4) and proximal femur using DEXA scan.

    • Main Results:

    • Women with premature menopause (EMP) showed significantly lower vertebral BMD compared to normal menopause (NMP) between ages 45-55.
    • Premature natural menopause (EMP) group had a higher prevalence of osteoporosis at the vertebral BMD compared to NMP and SUMP groups.
    • Surgical menopause (SUMP) women exhibited higher BMD than NMP women after age 55, particularly in mixed bone sites.

    Conclusions:

    • Both natural and surgical premature menopause are associated with reduced trabecular bone BMD in specific age segments compared to normal menopause.
    • Surgical menopause may confer a BMD advantage over normal menopause in later post-menopausal years (after 60).
    • The type and timing of menopause significantly influence long-term bone health trajectories.
