Osteoporosis is a bone disease where bone density and mass decrease, or bone structure changes, making bones weaker and more likely to fracture. ¹ With advancing age, the bone density normally decreases. However, in some people, it decreases faster. If bone density declines below a certain level, it is called osteoporosis. ² Osteoporosis is the leading cause of fractures in postmenopausal women and older men. ¹ Due to effective family planning policies since the 1960s, Singapore, a multi-ethnic country in Southeast Asia, has one of the fastest-ageing populations in Asia. ³ The proportion of citizens aged 65 and above increased from 9.9% in 2009 to 16.0% in 2019 and is projected to reach about 23.7% by 2030.⁴ In Singapore, the prevalence of osteoporosis ranges from 9.3% to 19.4% among postmenopausal women. The condition has a 0.7% prevalence among men aged 50 and older. ^5,6 In a population-based Singaporean study in 2020, researchers found that the risk level for starting osteoporosis treatment rises with age, from a 2.96% chance of a major fracture at age 50 to 32% at age 90. They also noted that 7% of the 29,323 women had previously experienced a fragile bone fracture. ⁷
