Core Viewpoint - Osteoporosis is a significant health issue, particularly among the elderly, affecting quality of life and life expectancy, with the theme for World Osteoporosis Day being "Healthy Weight, Strong Bones" [1] Group 1: Osteoporosis Overview - Osteoporosis is characterized by a decrease in bone density, leading to fragile bones that are more susceptible to fractures [1][3] - The process of bone loss is often unnoticed until a fracture occurs, with hip fractures being particularly dangerous for the elderly [5] Group 2: Epidemiology - The prevalence of osteoporosis in China is 19.2% among individuals over 50 years old, rising to 32.0% for those over 65, with a stark gender disparity: 10.7% in men versus 51.6% in women [7] - Among women over 50, approximately one in three is affected by osteoporosis, and this ratio increases to over 50% by age 65 [9] Group 3: Weight and Bone Health - Both underweight (BMI < 18.5) and obesity (BMI > 35) can negatively impact bone health, increasing the risk of fractures [11][15] - Underweight individuals may suffer from nutrient deficiencies that weaken bone strength, while obesity can lead to chronic inflammation and increased fall risk [11][13] Group 4: Lifestyle Factors - Young people are increasingly at risk for osteoporosis due to lifestyle choices, such as excessive sun protection leading to vitamin D deficiency and high consumption of coffee and alcohol [18] - Common misconceptions include the belief that osteoporosis is untreatable or an inevitable part of aging, whereas it can be prevented and treated effectively [20] Group 5: Prevention Strategies - Experts recommend four key strategies for preventing osteoporosis: regular sun exposure, balanced nutrition rich in calcium, weight-bearing exercises, and avoiding harmful habits like smoking and excessive alcohol consumption [22]
