Understanding Osteoporosis Prevalence in Iran
The phenomenon of population aging is accelerating globally, and Iran is no exception. With this demographic shift comes an increase in age-related chronic diseases, including osteoporosis, which poses a significant challenge to the country's healthcare system. Osteoporosis is a disease characterized by reduced bone mass and structural deterioration, which weakens bones and raises the risk of fractures. Given the serious complications associated with osteoporotic fractures, understanding the prevalence and its contributing factors is essential for effective public health planning and interventions. Data from multiple studies, including systematic reviews and meta-analyses, provide a comprehensive picture of the high burden of this disease among Iran's elderly population.
Overall Prevalence in Iran's Elderly Population
Recent meta-analyses combining data from various studies have provided the most reliable estimates of osteoporosis prevalence in Iran's aging population. A comprehensive meta-analysis published in 2022 found that the pooled prevalence of osteoporosis among Iranians over 60 years of age was approximately 34%. This research, which included 30 studies with a large sample size, also revealed a higher prevalence of osteopenia (low bone density) at 47%. The findings highlight that nearly one-third of the elderly population already suffers from osteoporosis, while nearly half are at an increased risk due to low bone density.
Gender and Regional Variations
The prevalence of osteoporosis is not uniform across the population and shows significant differences based on gender and location. While women typically face a higher risk globally due to hormonal changes, particularly after menopause, some studies in Iran present complex regional data.
- Gender Disparities: A 2023 meta-analysis focusing on Iranians aged 50 and older found a higher prevalence in women (38%) compared to men (25%). However, other studies provide differing gender-specific figures, with some reporting higher prevalence in men over 60 (41%) than women (34%) in that age group, based on analysis from the same 2022 meta-analysis mentioned earlier. These conflicting results indicate regional variations or differences in methodology and reference values used across studies.
- Regional Differences: Studies have shown considerable variation across different cities and provinces of Iran. For example, a 2021 study of the elderly in the Bushehr region reported age-standardized osteoporosis prevalence of 62.7% in women and 24.6% in men. These disparities underscore the need for local-level data to inform targeted public health interventions.
| Area of Measurement | Women (%) | Men (%) |
|---|---|---|
| Total Osteoporosis (≥50) | 38% | 25% |
| Spinal Osteoporosis (≥50) | 29% | 16% |
| Femoral Neck Osteoporosis (≥50) | 19% | 19% |

Key Risk Factors for Osteoporosis
Beyond gender and age, several modifiable and non-modifiable factors contribute to the high prevalence of osteoporosis in Iran's elderly population. Addressing these factors is crucial for effective prevention and management strategies.
- Dietary Deficiencies: The per capita consumption of dairy products in Iran is significantly lower than the global standard, and vitamin D deficiency is common. These deficiencies are major risk factors for low bone density and osteoporosis.
- Lifestyle Choices: Studies have identified a correlation between osteoporosis and certain lifestyle habits. Low levels of physical activity, sedentary lifestyles, and smoking are significant contributing factors.
- Comorbidities and Health Conditions: Several chronic illnesses and health-related factors increase the risk of osteoporosis. These include a history of bone fractures, renal or liver diseases, hyperthyroidism, and diabetes (though diabetes can sometimes act as a protective factor for certain sites).
- Other Factors: Other important risk factors include opioid use, low BMI, and certain ethnic backgrounds, such as Kurdish ethnicity in one study. For women, a higher number of pregnancies (parity) and longer periods of breastfeeding have also been identified as risk factors.
Health and Economic Consequences
The high prevalence of osteoporosis among the elderly in Iran leads to significant health and economic burdens. The primary clinical consequence is an increased risk of bone fractures, which can lead to severe complications, disability, reduced quality of life, and even increased mortality. Economically, the cost of treating osteoporotic fractures is substantial and is projected to rise dramatically with the country's aging population. These costs include hospitalization, surgery, and long-term care.
- Increased Fracture Incidence: The most immediate and dangerous consequence of osteoporosis is the increased risk of fractures, especially hip fractures, which have a high mortality rate and can lead to long-term disability.
- Impaired Quality of Life: Osteoporosis and related fractures can severely impact an elderly person's quality of life, leading to chronic pain, reduced mobility, and a higher chance of psychological issues like depression.
- Economic Burden: With an aging population and high prevalence of osteoporosis, the healthcare costs associated with treatment, particularly for fractures, place a significant financial strain on the health system and families.
Strategies for Prevention and Policy Implications
Addressing the growing challenge of osteoporosis in Iran's elderly population requires a multi-pronged approach involving both public policy and individual behavior changes. Health policymakers and stakeholders must consider evidence-based interventions to manage and mitigate this public health issue. A crucial starting point for effective planning and intervention is accurate epidemiological data, as highlighted by the research published in BMC Geriatrics in 2025.
Preventative Measures
- Nutritional Enhancement: Promote higher intake of calcium and vitamin D through diet and supplementation. Fortifying dairy products is a simple, effective measure to address widespread dietary deficiencies.
- Promote Physical Activity: Encourage regular, weight-bearing exercise among all age groups, but especially the elderly, to improve bone density and strength.
- Screening and Early Detection: Implement nationwide screening programs for osteoporosis and osteopenia to identify at-risk individuals early. This allows for timely intervention before a fracture occurs.
- Public Awareness Campaigns: Educate the public on the risk factors for osteoporosis and the importance of preventive measures. Raising awareness about the disease can lead to lifestyle changes that benefit long-term bone health.
- Targeted Interventions: Design and implement specific interventions for high-risk groups, such as postmenopausal women or individuals with low BMI or comorbidities.
Policy Recommendations
- National Strategy on Aging: Develop a national strategy on aging that prioritizes healthy aging, including dedicated resources and services for geriatric care.
- Resource Allocation: Increase budget allocation for geriatric care and research, focusing on preventative strategies and effective resource management.
- Integrated Care Models: Establish integrated care models that coordinate services for the elderly, improving access and continuity of care for chronic conditions like osteoporosis.
- Insurance Coverage: Expand insurance coverage to include long-term care and home care services for the elderly, reducing the financial burden on patients and families.
Conclusion
Osteoporosis is a widespread and serious health concern among the elderly population of Iran, with prevalence rates reaching approximately one-third of those aged over 60, and almost half experiencing low bone density. This high prevalence is influenced by a combination of demographic trends, genetic predispositions, and modifiable lifestyle factors such as poor nutrition and low physical activity. Given the rising incidence and associated high costs, both in terms of patient quality of life and healthcare expenditures, a concerted public health response is imperative. By implementing targeted strategies focused on nutrition, exercise, early screening, and improved healthcare policy, Iran can mitigate the growing impact of osteoporosis and ensure a healthier future for its aging population.
