Osteoporosis affects 22.8% of Italian women and 14.5% of men over 60, increasing fracture risk. Muscle mass and body fat, influenced by hormones like leptin, play key roles in bone health and osteoporosis development.

Area of Science:

  • Gerontology
  • Orthopedics
  • Endocrinology

Background:

  • Osteoporosis is a significant health issue in Italy, particularly among the elderly.
  • Sarcopenia, characterized by muscle mass and strength reduction, is linked to aging and increases fracture risk.
  • Bone health is influenced by muscle strength, body composition, and hormonal factors.

Purpose of the Study:

  • To investigate the prevalence of osteoporosis in Italy.
  • To explore the relationship between sarcopenia, muscle strength, and bone health.
  • To examine the role of body fat mass and leptin in osteoporosis.

Main Methods:

  • Analysis of epidemiological data on osteoporosis prevalence in Italian adults aged 60 and over.
  • Assessment of the association between muscle mass, strength, and bone parameters.

  • Evaluation of the correlation between body fat, leptin levels, and bone mineral density.

    • Main Results:

    • Osteoporosis prevalence is 22.8% in women and 14.5% in men aged 60+.
    • Sarcopenia is more prevalent in women and is associated with increased fracture risk.
    • Higher body fat mass shows a protective effect against osteoporosis, mediated by hormonal and mechanical factors, including leptin.

    Conclusions:

    • Osteoporosis is highly prevalent in older Italians, with significant gender disparities.
    • Muscle strength and body composition are critical determinants of bone quality and fracture risk.
    • Leptin and body fat play a complex role in bone metabolism, potentially offering a protective effect against osteoporosis.
