RESUMEN
BACKGROUND: The rates of obesity among immigrant populations within the USA rise with increasing duration of residency. The aims of this study were to examine weight self-perception and body image discrepancy within a large community sample of Hispanic and Somali predominantly immigrant adults. METHODS: Utilizing a community-based participatory research (CBPR) approach to collect survey data from a sample of adults who self-identified as Hispanic, Latino, or Somali in Southeast Minnesota. Correlations among actual body mass index (BMI), perceived weight category, and perceived body size were assessed with Spearman rank correlation coefficients. Associations of weight loss intentions with actual BMI, perceived weight category, perceived body size, and body image discrepancy were assessed using Kruskal-Wallis nonparametric tests. RESULTS: A total of 1256 adults completed the survey and biometric measurements (610 Hispanic, 646 Somali); 81% (457) and 50% (328) had a BMI in the overweight or obese category in the Hispanic and Somali cohorts, respectively. Among participants with a BMI of > 25, more participants reported a perceived body size that was overweight or obese than a perceived weight category that was in the overweight or obese category (79% vs. 48%, p = < 0.0001). Body image discrepancy, but not actual BMI, was associated with weight loss intentions for both groups. Perceived body size and perceived weight category were associated with weight loss intentions for Hispanic participants only. CONCLUSIONS: Perceived body size is a more accurate self-report proxy of BMI-defined weight status compared with the perceived weight category among Hispanic and Somali immigrant groups. Body image discrepancy may be more predictive of weight loss intentions than actual BMI.
RESUMEN
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.
