Large-Scale, Community-Wide Preventive Initiative Dramatically Impacts CV Risk Profile
A population-wide community and clinical prevention program involving 10,000 adults meaningfully reduced the cardiovascular (CV) risk profile among a substantial portion of the population as indicated by those participating in screenings. Findings also indicate the level of improvements differ by gender for specific cardiovascular risk factors. The results will be presented March 25 at the 61st annual American College of Cardiology (ACC) scientific session.
Hearts Beat Back: The Heart of New Ulm Project (HONU) is a demonstration project aimed at reducing heart attacks and coronary heart disease in the rural Minnesota community of New Ulm. The project is a collaborative partnership of Allina Hospitals & Clinics, the Minneapolis Heart Institute Foundation, New Ulm Medical Center and the community of New Ulm. The 10-year goal is reduction of acute heart attacks, or myocardial infarctions, and the five-year goal is to reduce modifiable heart disease risk factors at a community level. These short-term outcomes provide evidence that the program is having a positive impact on the health at a population level.
"Due to the single medical center in the community, all residents are connected to a common set of providers and common electronic health record, which is uniquely helpful in providing a comprehensive understanding of risk levels that can be communicated back to the residents and medical providers to close the loop of the patient care continuum," said study co-investigator Jackie Boucher, MS, vice president of education at the Minneapolis Heart Institute Foundation.
For the residents of the New Ulm zip code, free heart health screenings were offered to any adult first in 2009 when the program began and again in 2011. Screenings were held in a variety of locations, including worksites, the local hospital (New Ulm Medical Center), churches and other community spaces. Those participating in both years of the free screenings comprised the study group, which included 1,766 adults. Mean age of re-screening cohort in 2011 was 55.5.
During the screenings, study participants completed a questionnaire and biometric measures (i.e., blood pressure, height, weight, waist circumference and fasting blood draw). The screening tool included questions on various lifestyle behaviors, including smoking, physical activity level, number of daily fruit and vegetable servings, stress level, alcohol consumption and medication adherence. After the screening, high-risk individuals were targeted for more aggressive treatment with direct phone calls to provide behavioral lifestyle change counseling, medication initiation and scheduling of follow-up visits with primary care providers at the New Ulm Medical Center.
The researchers found that people returning for screening in 2011 were more likely to be female (64 percent of the returnees in 2011 were women), less likely to be smokers (6.3 percent in 2011 vs. 5.3 percent in 2009), be obese (35.6 percent in 2009 vs. 36 percent in 2011) or have diabetes (23.2 percent in 2011 vs. 26.6.
Reductions were found in smoking, stress levels, hypertension, hyperlipidemia, fasting glucose and high-sensitivity C-reactive protein (hs-CRP) across genders, as well as an increase in optimal weekly exercise.
Gender-specific differences also were revealed, as women had larger decreases in stress levels and larger increases in fruit and vegetable consumption compared with men, and men were more likely to start blood pressure medications. Also, hs-CRP decreases were more pronounced in women than men despite similar changes in aspirin use and non-significant gender differences in cholesterol medication use. The study authors hypothesize that this may be related to increased exercise and reduced stress levels.
"In general, the behavioral change initiatives are having a greater impact on the female population of this widespread preventive program," said Knickelbine. "We will continue to monitor the entire population within New Ulm, and provide feedback to both individuals and the community."
