Abstract
Purpose:
To evaluate a healthy eating and physical activity intervention for immigrant families, derived through community-based participatory research.
Design:
The Healthy Immigrant Families study was a randomized controlled trial with delayed intervention control group, with families as the randomization unit.
Setting:
US Midwest city.
Participants:
Participants were recruited by community partners from Hispanic, Somali, and Sudanese immigrant communities.
Intervention:
Family health promoters from participating communities delivered 6 healthy eating modules, 4 physical activity modules, and 2 modules synthesizing information in 12 home visits (60-90 minutes) within the first 6 months. Up to 12 follow-up phone calls to each participant occurred within the second 6 months.
Measures:
Primary measures were dietary quality measured with weekday 24-hour recall and reported as Healthy Eating Index score (0-100) and physical activity measured with accelerometers (14 wear days) at baseline, 6, 12, and 24 months.
Results:
In total, 151 persons (81 adolescents and 70 adults; 44 families) were randomly assigned. At 12 months, significant improvement occurred in Healthy Eating Index scores for adults in the intervention group compared with controls (change, +8.6 vs −4.4; P < .01) and persisted at 24 months (+7.4 from baseline; P < .01). No differences were observed for adolescents and no significant differences occurred between groups for physical activity.
Conclusion:
This intervention produced sustained dietary quality improvement among adults but not among adolescents. Program outcomes are relevant to communities working to decrease cardiovascular risk among immigrant populations.
