Health education intervention may promote healthier lifestyle in underserved communities
A unique study conducted in a multi-ethnic, underserved community in New York City shows if young adults are properly taught about heart healthy behaviors and strictly adhere to specific interventions, they may see significant benefits to their cardiovascular health when compared to those who do not have any health education intervention, according to Mount Sinai researchers. Their findings also suggest that showing young adults ultrasound images of plaque in their arteries can provide helpful information to improve their cardiovascular health and their future lifestyle.
The study is part of an ambitious, multinational effort to intervene early in the lives of children so they can form a lifetime of heart healthy habits. These new results come after a highly successful intervention involving more than 500 preschoolers at 15 head start schools in the Harlem section of Manhattan, an urban area that is socioeconomically disadvantaged-;a situation commonly linked to higher rates of obesity, heart disease, and other health issues. It showed students who went through a specialized health curriculum significantly improved their attitudes and behaviors about a healthy lifestyle, including diet, exercise and heart health.
Researchers focused on caretakers of preschool students in those same Harlem schools (parents, family members, teachers and school staff). Valentin Fuster, MD, PhD, Director of Mount Sinai Heart and Physician-in-Chief of The Mount Sinai Hospital, created and led the trial, called the FAMILIA Project at Mount Sinai Heart. Results were published in the November 11 issue of the Journal of the American College of Cardiology and will be presented on November 17 during the American Heart Association's Scientific Sessions 2019.
The FAMILIA team enrolled 635 preschool caregivers in 15 different Head Start schools in Harlem (average age 38 years old, 83 percent female, 57 percent Hispanic/Latino and 31 percent African-American). Harlem's population is predominantly African American and Hispanic/Latino-;groups that experience a higher risk of cardiovascular disease. One control group and two different intervention groups went through the program for approximately a 12-month period. Before the intervention began, researchers gave the adults an individualized health assessment that included measurements of weight, blood pressure, body mass index, lipid profile, and blood glucose. Caregivers also had vascular ultrasounds to determine if they had plaque in their arteries and received printed photos of those scans, along with handouts on heart health, controlling weight, and portion control.
All participants answered a comprehensive questionnaire before the study began to measure their knowledge, attitudes, and habits about their health. Questions addressed their nutrition, physical activity, tobacco use, alcohol consumption, if they have conditions such as heart disease or diabetes and a family history of health problems.
One intervention group went through an "Intensive Individual Intervention Program" (IIIP), where they had one-on-one counseling sessions with a trained lifestyle coach and followed a manual created by the FAMILIA team. Monthly coaching session topics included health and heart disease, eating habits, shopping for healthy food on a budget, cooking healthy, exercise, and stress management. Caregivers also got an activity-monitoring device to wear for tracking physical activity and provide motivation for exercise.
The other intervention group went through "Peer-to-Peer Program Intervention" (PPPI) where they went to monthly peer-led support group sessions. During each session, they followed a curriculum designed by the FAMILIA Team that focused on health and heart disease, eating habits, shopping for healthy food on a budget, cooking healthy, exercise, being active as a family and stress management.
Adults in the control group did not have a structured program. Instead, they received "Family Newsletters" (also handed out to intervention groups) that talked about diet and exercise and provided activities and at-home routines to follow with their children.
Researchers analyzed all participants 12 months after the study began and gave them the same health assessment with a vascular ultrasound. the validated Fuster-BEWAT Score (B-blood pressure, E-exercise, W-weight, A-Alimentation, T- Tobacco) to measure results. The overall BEWAT score ranges from zero (poor health) to 15 (ideal cardiovascular health). Baseline for participants was 9.3.
Results show caregivers who participated and strictly adhered to at least 50 percent of the curriculum had a greater and statistically significant change in their BEWAT Score compared to caregivers who went through less than half of it. Adults with high adherence improved scores by approximately 0.30 points from baseline at 12 months compared to low adherence caregivers. This data leads researchers to conclude that closely following lifestyle interventions may greatly improve health outcomes.
Another important finding was that caregivers in the intervention groups with evidence of atherosclerosis in vascular ultrasounds going into the study had the strongest results and most improvement following the intervention. Seeing pictures of their plaque and understanding what the images showed significantly boosted the interventional effects. Additionally, caretakers with a lower baseline score who had atherosclerosis at the start of the study benefitted the most from the intervention. Researchers conclude if caretakers learn they may have heart issues early on, early intervention could prevent them from having future cardiac events like heart attack and stroke.
At 12 months, both the control and intervention groups improved their BEWAT scores by an average of .20 points (modest change) from the baseline score of 9.3, mainly driven by higher exercise and blood pressure scores.
The FAMILIA team then evaluated participants again at 24 months, one year after stopping the intervention, but did not perform ultrasounds. Researchers observed caregivers with atherosclerosis at baseline and those who strongly participated in the intervention maintained healthier habits and had slightly higher BEWAT scores when compared to other caregivers in the interventional and control groups. They also found overall lack of intervention for the year led to similar BEWAT scores among plaque-free caregivers in the interventional and control groups.
FAMILIA follows other successful interventions in children and caregivers led by Dr. Fuster in Colombia and Spain, but FAMILIA is unique in being the first time the health promotion curriculum was family-based and implemented in a multi-ethnic, underprivileged urban population. Dr. Fuster and his team plan to expand the program across the five boroughs of New York City. This ambitious project will also evaluate how family socioeconomic status and teachers' characteristics may affect the implementation and the efficacy of school-based health promotion programs.
