BACKGROUND: US immigrants often have escalating cardiovascular risk. Barriers to optimal physical activity and diet have a significant role in this risk accumulation.
METHODS: We developed a physical activity and nutrition intervention with immigrant and refugee families through a community-based participatory research approach. Work groups of community members and health scientists developed an intervention manual with 12 content modules that were based on social-learning theory. Family health promoters from the participating communities (Hispanic, Somali, Sudanese) were trained to deliver the intervention through 12 home visits during the first 6 months and up to 12 phone calls during the second 6 months. The intervention was tested through a randomized community-based trial with a delayed-intervention control group, with measurements at baseline, 6, 12, and 24 months. Primary measurements included accelerometer-based assessment of physical activity and 24-hour dietary recall. Secondary measures included biometrics and theory-based instruments.
RESULTS: One hundred fifty-one individuals (81 adolescents, 70 adults; 44 families) were randomized. At baseline, mean (SD) time spent in moderate-to-vigorous physical activity was 64.7 (30.2) minutes/day for adolescents and 43.1 (35.4) minutes/day for adults. Moderate dietary quality was observed in both age groups. Biometric measures showed that 45.7% of adolescents and 80.0% of adults were overweight or obese. Moderate levels of self-efficacy and social support were reported for physical activity and nutrition.
DISCUSSION: Processes and products from this program are relevant to other communities aiming to reduce cardiovascular risk and negative health behaviors among immigrants and refugees.
TRIAL REGISTRATION: This trial was registered at Clinicaltrials.gov (NCT01952808).
