Understanding the Statistics: How Common Is Osteoporosis?
Data from the Centers for Disease Control and Prevention (CDC) from 2017–2018 revealed that the age-adjusted prevalence of osteoporosis among adults aged 50 and over was 12.6%. This statistic represents millions of individuals whose daily lives are impacted by a condition that often goes undetected until a fracture occurs. Beyond the diagnosed cases, millions more are at increased risk due to low bone mass, a precursor to osteoporosis. The numbers highlight not only the scale of the problem but also the critical need for awareness, diagnosis, and intervention strategies.
Prevalence by Demographics
Osteoporosis does not affect all Americans equally. The risk factors and prevalence rates vary significantly across different demographic groups, particularly by gender, age, and race/ethnicity.
Gender Disparities
In the U.S., women are disproportionately affected by osteoporosis. In the 2017–2018 survey, the age-adjusted prevalence was 19.6% for women compared to just 4.4% for men aged 50 and over. Postmenopausal women face a heightened risk, primarily due to a sharp decline in estrogen levels, a hormone vital for maintaining bone density. While often perceived as a 'woman's disease,' osteoporosis in men is a serious and growing concern, with an estimated 2 million American men over 50 affected. A man over 50 is more likely to break a bone due to osteoporosis than to get prostate cancer, highlighting the often-underestimated risk in males.
Age and Race/Ethnicity Trends
Age is another critical factor influencing osteoporosis prevalence. Unsurprisingly, rates increase with age. The 2017–2018 CDC data shows that among adults 50 and over, prevalence was significantly higher in the 65+ age group (17.7%) compared to the 50–64 age group (8.4%). Racial and ethnic background also plays a role, with non-Hispanic white and Asian women having the highest risk for developing osteoporosis. However, men and women of all races and ethnic groups can develop the disease and are at risk for fracture.
Comparison of Osteoporosis & Low Bone Mass Prevalence (Adults 50+, 2017–2018)
| Demographic | Osteoporosis Prevalence | Low Bone Mass Prevalence |
|---|---|---|
| Total Adults 50+ | 12.6% | 43.1% |
| Women 50+ | 19.6% | 51.5% |
| Men 50+ | 4.4% | 33.5% |
| Women 65+ | 27.1% | 52.9% |
| Men 65+ | 5.7% | 40.7% |

The Alarming Rate of Undiagnosed Cases
One of the most significant challenges in addressing osteoporosis in the U.S. is the high rate of undiagnosed cases. A recent time trend analysis, using NHANES data from 2005–2018, found that nearly 70% of individuals with osteoporosis went undiagnosed. This means millions of people are living with a heightened risk of fractures without proper treatment or management. The study noted that undiagnosed rates were particularly high among men and younger adults (50–59) with the condition, indicating a major public health gap. Early diagnosis is critical because osteoporosis is treatable, and timely intervention can help prevent serious fractures and related complications.
The Economic and Health Burden
Beyond the individual's suffering, osteoporosis places a heavy financial and societal burden on the U.S. healthcare system. Fractures, especially hip fractures, are a leading cause of long-term disability, loss of independence, and even increased mortality, particularly in the first year after the injury. The costs associated with osteoporotic fractures are staggering. Estimates suggest that by 2025, osteoporosis could be responsible for three million fractures, leading to approximately $25.3 billion in costs. These costs include not only direct medical expenses but also indirect costs from lost productivity and caregiver burden.
Mitigating Risk and Preventing Fractures
While some risk factors, such as age, gender, and family history, are unchangeable, many can be managed. A multi-pronged approach combining lifestyle modifications, proper nutrition, and medical treatment can significantly reduce the risk of osteoporosis and related fractures. Key strategies include:
- Diet: Consuming adequate amounts of calcium and vitamin D is fundamental for strong bones. Dietary sources like dairy products, leafy greens, and fortified foods are important, as are supplements if needed.
- Exercise: Regular weight-bearing exercise (e.g., walking, dancing, jogging) and resistance training helps build and maintain bone density. Balance exercises, such as Tai Chi, can also reduce fall risk.
- Lifestyle: Avoiding smoking and limiting excessive alcohol intake are crucial for maintaining bone health.
- Fall Prevention: For individuals with weakened bones, preventing falls is paramount. This can involve making simple home modifications like adding grab bars, improving lighting, and removing trip hazards.
- Medication: For those at high risk or already diagnosed, prescription medications can help slow bone loss or even rebuild bone density. A doctor can determine the best course of treatment. The U.S. Preventive Services Task Force also provides up-to-date screening guidelines to help identify at-risk individuals.

Conclusion
Osteoporosis is a widespread and increasing health threat in the United States, particularly among older adults. With millions already living with the condition, and even more at risk, the need for increased public awareness, early diagnosis, and effective management is more critical than ever. The statistics reveal clear disparities among populations, emphasizing the importance of targeted preventative care. By understanding the prevalence and risk factors, individuals and healthcare professionals can work together to promote better bone health and reduce the devastating impact of fragility fractures on seniors across the country.
