Primary Care Engagement and Osteoporosis Fracture Risk: Findings from a Community Health Fair Screening Initiative
This study demonstrates that community health fair screenings in South Florida effectively identify a high-risk, medically complex population for osteoporosis, revealing that while lifestyle factors have minimal impact on fracture risk predictions, medical history and regular primary care engagement are the strongest determinants of FRAX scores.

Osteoporosis is a silent weakening of the skeleton, a condition where bones lose their density and become fragile, much like old wood that has lost its strength. It is a chronic disease that affects millions of people, particularly as they age, turning everyday movements into potential hazards for broken bones. The consequences of these breaks, especially in the hip, can be devastating, leading to long-term disability and a loss of independence. Because the disease often shows no symptoms until a fracture occurs, doctors rely on tools to estimate a person's risk before a break happens. One such tool, developed by the World Health Organization, calculates the probability of a major bone break over the next decade based on a person's age, sex, weight, and medical history, such as whether they have smoked, drink alcohol, or have previously broken a bone. This calculation helps determine who needs treatment, but it usually requires a visit to a primary care doctor. For many people, especially those in underserved communities, regular access to a doctor is limited, leaving a gap in who gets screened and who does not.
Researchers set out to explore whether community health fairs could bridge this gap. These events, held in neighborhoods across South Florida, offer a low-barrier way to reach people who might not otherwise seek medical advice. A team of medical students and faculty from Florida International University organized a screening initiative at these fairs, inviting adults aged 45 and older to answer a survey about their health habits and medical history. The goal was not just to calculate fracture risk for these individuals, but to understand how their connection to a regular doctor influenced that risk. The team asked participants how often they saw a primary care provider, what they ate, whether they took supplements, and if they had a history of conditions like cancer or arthritis. They then used the standard risk calculator to estimate each person's chance of a major fracture or a hip fracture in the next ten years.
The results revealed a surprising pattern regarding how often people saw their doctors. The researchers found that participants who reported seeing a primary care provider every few months had significantly higher calculated fracture risks than those who did not see a doctor regularly. At first glance, this might seem counterintuitive, as one might expect that frequent medical care would lead to better health and lower risk. However, the data suggests a different reality: people with more complex medical needs, such as a history of cancer, prior fractures, or other chronic conditions, are the ones who naturally seek out more frequent medical attention. In this group, the high risk was driven by these existing medical histories rather than a failure of care. The study showed that a person's medical history, including a past diagnosis of osteoporosis, a previous fracture, or a history of cancer, was the strongest factor in predicting future fracture risk. These medical factors explained a large portion of the variation in risk scores, far outweighing lifestyle choices.
In contrast, the study found that daily habits and lifestyle factors did not independently predict fracture risk in this specific group. The researchers looked closely at diet, including whether people ate meat or vegetables, and whether they took vitamins like calcium or vitamin D. They also examined smoking and alcohol consumption. None of these lifestyle variables showed a significant link to the calculated fracture risk when analyzed on their own. This does not mean that diet and exercise are unimportant for bone health in general, but rather that in this snapshot of a community health fair, the weight of a person's medical history was the dominant force. For instance, having a history of gastritis was unexpectedly linked to lower risk scores in the statistical models, though the researchers noted this might be a statistical quirk rather than a true protective effect, and they cautioned against interpreting it as a medical benefit.
The study also highlighted a critical gap in care. The group of participants who did not see a primary care provider regularly had the lowest calculated fracture risk scores. The researchers suggest this might not mean these individuals are actually healthy, but rather that their risks are hidden. Without regular visits to a doctor, these individuals may have undiagnosed osteoporosis, unrecorded past fractures, or unmanaged conditions that would normally raise their risk score. Because the risk calculator relies on information that is often only documented during medical visits, people without a regular doctor may appear to be low-risk when they are actually high-risk. This finding underscores the value of community health fairs as a place to identify high-risk individuals who are already engaged with the healthcare system, while also pointing out that those without regular care might be the most underserved and hardest to reach.
Ultimately, the research suggests that community screenings are effective at identifying people with complex medical needs who are already in the system, but they also reveal the limitations of self-reported data for those outside the system. The medical students who conducted the screenings reported feeling more confident in their ability to assess risk and counsel patients after the experience, finding the process valuable for their training. The study concludes that while lifestyle factors are important, the history of a patient's medical conditions is the primary driver of fracture risk in this population. It serves as a reminder that for those without regular access to a primary care provider, their true risk of breaking a bone may be underestimated, and that community-based initiatives play a vital role in bringing these hidden risks to light.
