Health fair referrals shown to help improve blood pressure among low-income immigrants
UCLA researchers sought to compare how two different approaches to providing follow-up care to health fair participants impacted blood-pressure control.
The study looked at data on 100 middle-aged men and women from low-income immigrant communities in Los Angeles who had their blood pressure checked at a health fair. Some were assigned to a community nurse who held office hours at a church, provided patients with in-person counseling on lifestyle modification, and helped them make doctors appointments. Others were assigned to research assistants who aided them solely by phone in scheduling appointments with physicians. One-quarter of the participants had not been previously diagnosed with hypertension.
The researchers found that while patients in both groups showed improvement in systolic blood pressure, those in the phone-assisted group had twice the improvement (an average 14±15 mm drop) of those in the nurse group (an average 7±15 mm drop). While it is unclear what caused the more pronounced short-term improvement in the phone-assisted group, researchers suspect these participants saw a physician sooner and had more adjustments to their medications within the four-month study period.
Assisting health fair participants with making an appointment to see a doctor led to a significant improvement in blood pressure. Health fairs can play a role in identifying people with treatable chronic conditions in low-income immigrant communities and can provide an opportunity to connect people with medical care.
